Automotive electrical systems contain multiple electrical connections between the various electronic modules and/or sensors of the vehicle. An example of such electrical connection may be a connection between the oxygen sensor in the exhaust gases and the engine control unit (BUD). The oxygen sensor in the exhaust gases (hereinafter referred to simply oxygen sensor)installed in the exhaust system (EXHAUST gas) of the vehicle, measures the oxygen content in the exhaust gases of the internal combustion engine. The signal from the oxygen sensor comes in BUD, which changes the ratio between air and fuel supplied to the engine fuel mixture.

The oxygen sensors are installed in manufacturing plants, combined with the BUD of different kinds of connectors. The wires from the oxygen sensor end with end connector which may be the implementation is in the form of pin or socket contacts. The end connector of the oxygen sensor is connected with a respective end connector of the car, connected the wiring harness from the BUD. Both halves of the connector, usually made of plastic, provide waterproof mechanical and electrical connection wires.

Every car manufacturer uses to connect oxygen sensor with the car wiring harness specific set of connectors. Manufacturers of oxygen sensors that are installed at the manufacturing plant hire, must supply the sensors with connector compatible with the connector, which uses a car manufacturer. The necessity of combining connectors associated with the loss of time waiting for the delivery of the motor-car manufacturer of oxygen sensors with a corresponding connector and creates additional problems for after-sales maintenance and repair of vehicles (in particular, when replacing sensors).

Small repair shops and suppliers of spare parts for retail sale usually do not have large enough storage space and cannot store different oxygen sensors for cars of all models and brands. In the absence of stock required sensor must be ordered from the original equipment manufacturer (OEM), which is s not always have the desired sensor in stock and have to order it on their wholesale basis.

Summary of the invention

The present invention was based on the task to save the player from having to supply aftermarket car service replacement of electrical equipment with certain connectors.

Before a detailed description of one of the embodiments of the invention, it should be noted that the invention is not limited by the description of the various structural parts and their mutual location shown on the drawings. The invention covers other designs offered in it devices and other ways of its implementation and use. It should also be noted that in the description, the terms are only illustrative of the invention and should not be construed as limiting its scope. The terms "including" and "comprising" and its derivatives mean that part of a device or element along with other parts are all listed after these words and equivalent details.

Suppose the equipment variant embodiment of the invention

Figure 1 shows the basic connection of complete oxygen sensor 10 installed on the vehicle at the factory with the wiring harness to the electrical system of the vehicle. Complete oxygen sensor 10 contains the actual oxygen sensor 14 mounted in the EXHAUST system of the vehicle, conventionally indicated in the drawing position 15. The oxygen sensor 14 can not only into the exhaust pipe 15, but also to consolidate it through not shown in the drawing corresponding flange. The oxygen sensor 14 must be installed so that its front end was in the exhaust gas stream 16 (see arrows in figure 1). With the oxygen sensor 14 are connected by insulated wires 18 are located at the end of the end connector 22 of the sensor. The number of wires 18 can be different and depends on the type installed on the car of the oxygen sensor 14. Typically, the oxygen sensor has three or four wires 18. To protect the wires 18 from external influences their enclosed in a flexible sheath 24.

Complete oxygen sensor through the end connector 26 of the electrical system of the vehicle is electrically connected to not shown in the drawing, the engine control unit (BUD). BUD is connected with an end connector 26 isolated wires 30.

As noted above, when considering the pre is osilac the invention, every car manufacturer uses a specific automotive connector 26 and the connector 22 of the oxygen sensor. Suppliers of complete sensors 10 oxygen should, obviously, be included in the kit connector, which uses a car manufacturer. The connectors 22 and 26 provide mechanical and electrical connection of the oxygen sensor 14 with BUD, reliably protecting the connector from external influences during operation of the vehicle. Proposed in the present invention solutions in no way connected with the construction shown in figure 1 specific connectors 22 and 26 so in the description are not considered.

Figure 2-7 shows the proposed invention is a universal repair kit 34 with a new set on the car instead of a failed oxygen sensor, designed for the automotive aftermarket. Use the repair kit 34 allows you to replace your existing car failed complete oxygen sensor, installed at the factory car, regardless of the design of automotive connector 26 and the connector 22 of the sensor.

Shown in figure 3 repair kit 34 includes a sensor 38 oxygen United with him by the isolated wires 42 enclosed in a flexible sheath 44 (smfg). As noted above, the number of wires 42 may be different, however, most of the sensors have three or four wires. Unlike wires installed on the car complete gauge 10 wire oxygen sensor 42 repair kit does not end with the connector. Each wire 42 has a free end 46 (see Fig.7). The insulation of the wires 42 can reach the end 46 of the wire or it can be partially cut off, revealing the ends of the wires for subsequent splicing.

As part of repair kit 34 preferably having a valve 50 for splicing described below by way of the free ends 46 of the new sensor with the wires 18 are available on the vehicle sensor. In this embodiment, the valve 50 is designed for splicing wires, consists of four separate neovisnih connector 54 type POSI-LOCK. Such connectors 54 are protected by patents US 5228875, US 5695369, US 5868589 and other pending applications and are delivered by the company Swenco Product, poplar bluff, PCs Missouri. Figure 4 shows the interface 56 are connected by bonding wires. In principle, for splicing wires, you can use the armature 50 of any type, including various not shown in the drawings, the mechanical connectors. When using such mechanical connectors may be a need for any additional the part not shown in the drawings, components.

Part repair kit 34 also includes a two-part protective box 58 with the base 62 and the cover 66. Protective box 58, within which is located the junction 56 connected by bonding wires 18 and 42, protects the connection wires from external influences during operation of the vehicle. As shown in detail in figure 3-5 and 7-8, the base 62 of the box or casing 70 has an open end 74 with holes in which are placed the armature 50 and the sealing ring 118 and the end wall 78 with holes for the output wires. Inside the housing 70 made four isolated from each other holes 82, passing along its length from the open end 74 to the wall 78 with holes for the output wires. Each hole 82 has a first practically constant in the greater part of the length of the housing 70 diameter.

The end wall 78 of the case is made of the boss 86. As shown in figure 4, the lug 86 forms in the hole 82 of the flange, and therefore inside the bosses 86 holes 82 have a second diameter, somewhat smaller first diameter. More purpose bosses 86 and the holes of the second diameter are discussed below. In the end walls of the bosses 86 holes 90 for output wires connected to the corresponding holes 82 (see figure 5). The diameter of each of holes 90 is less than the first and second diameters of the holes 82. Across the holes 90 of the wire 18 or 42 out of the housing 62 to the outside.

On each side of the body 70 (62) near the end 74 with open holes are ledges 94. The tabs 94 are intended for fastening to the housing 70 (62) of the cover 66, as described in more detail below.

As shown in figure 4, the dimensions of the cover 66 correspond to the dimensions of the end face 74 of the housing 62 with the open ends of the holes. On two opposite sides of the cover 66 is located at an angle of 180° to each other, made two elastic locking tabs 98. The legs 98 has openings 102, which includes protrusions 94. When the cover 66 is clamped put on the housing 62, the inclined surfaces of the protrusions 94 are bent outward elastic locking tabs 98 and the tabs 94 are completely inside the hole 102 98 feet that snap over the tabs 94 and hold the housing and the cover in the assembled condition. On the other two sides of the cover 66 is made cutouts 106, which includes the remaining free two tabs 94 of the housing. This method of securing the cover 66 to the housing 62 by using tabs and tabs allows you to secure the cover on the housing, regardless of their relative position.

As shown in figure 4 and 6, the cover 66 also has a boss 110, an internal diameter which is essentially equal to the second diameter of the holes 82 and the inner diameter of the bosses 86 of the housing. More purpose bosses 110 are discussed below. In the end walls of the base 110 is made holes 114 for pickup is and wires, passing inside the base 110 and the cover 66. Preferably, the holes 114 through which the wires 18 and 42 pass through the cover 66, had the same diameter as the holes 90.

Protective box 58 is preferably made of plastic by injection molding, however, it can also produce and from any other appropriate material. The invention is not limited to the design of the protective box 58, shown in the drawings. Thus, in particular, box 58 can be performed with less, and with a large number of holes to connect the wires. In addition, for securing the cover 66 to the housing 62 can be used not shoulders, and legs, and is totally different device.

In the repair kit 34 includes multiple sealing rings 118, intended for the formation of a watertight seal around the junction 56 connected to each other with wires. Each sealing ring 118 has a front end face 122 and the rear end 126 and is performed on the outer surface of the annular projections. A through hole 130 (see figure 3) in the center of the ring 118 is intended for the passage through it of connected wires. As shown in figure 4, 7 and 8, the wire 18 or 42 is inserted into the hole 130 of the ring 118, which then pull on the wire 18 or 42 on a tight waterproof fit between the wire and the ring. The diameter of the front portion 122 of the ring with the em to the inner diameter of the bosses 86 or 110. On the rear side 126 of the ring made of several annular projections 134, which are tightly pressed against the walls of the hole 82 of the housing 70, forming a waterproof seal located in the housing 62 of the junction 56 interconnected wires.

The sealing ring 118 can be made of any elastic material, for example silicone. In the present embodiment, repair kit 34 has eight sealing rings 118, the actual number may be less or more depending on the number of connected wires 42. In addition, the rear portion 126 of the rings may have not three, but more or fewer annular projections 134. It is obvious that the sealing ring may have another structure.

Figure 4 shows two opposite pairs of sealing rings 118, which are located at opposite ends of the connector 54. It should be noted that in the proposed invention the team protective box between the sealing rings 118 and the ends of the connector 54 can leave gaps. In other words, the sealing ring 118 provide the necessary sealing of the holes 82, regardless of whether they pressed the ends of the connectors 54, or between them remain small gaps. This design of the sealing rings allows the use of different kinds designed for splicing wire is in the connection of the valve 50. It is obvious that the compression of the sealing rings 118 connectors 54 and extending in the radial direction can also ensure the necessary seal.

Below is a way to install on car universal repair kit 34 with an oxygen sensor, which replaces installed on the car and the failed sensor. First, cut the wires 18 connecting mounted on the vehicle, the oxygen sensor 14 with its end connector 22, remove the oxygen sensor 14 from the vehicle. To facilitate installation, repair kit 34 connected to the connector 22 of the wire 18 must have a sufficiently large length. Then, as shown in Fig.7, wire put on the box 58 and the o-ring 118. Next on the wire 18 is put on the housing 62, missing the cut ends of the wires through the holes 90. After that, the housing 62 shift by wire 18 to the end connector 22 of the sensor. Then wire 18 put four sealing rings 118, as shown in the drawing.

Next to the wires 42 connected to the newly installed sensor 38, put on the lid 66. The free ends 46 of the wires 42 are passed through corresponding holes 114 of the cover and slide the cover 66 to the sensor 38. Then wire 42 put four remaining sealing ring 118, as shown in the drawing. Obviously, chocobos 62 and the cover 66 can be swapped and wire 42 to put on the housing 62, and wire 18 to the cover 66. The sequence of the housing Assembly 62 and the cover 66 with wires can also be changed " on the reverse.

Then, as shown in Fig, the cut ends of the wires 18 and the free ends 46 of the wires spliced to each other using connectors 54 or any other intended for splicing wire armature 50. In addition, connect the wires at the interface 56 by welding or soldering. After connecting the wires in the junction 56 of the housing 62 and the cover 66 to move toward each other as indicated by arrows in Fig. When the movement of the body 62 and the cover 66 of the front sections 122 of the sealing rings 118 are inside the respective bosses 86 and 110, and the annular protrusions 134 are pressed against the surface of the respective holes 82 within housing 62. The body 62 and the cover 66 to move the latching legs 98 of the cover corresponding to the respective protrusions 94 of the housing. In the proposed repair kit joint 56 is electrically connected with each other by wires securely protected during vehicle operation from external influences by a protective box 58 and the o-rings 118. Proposed in the invention is a universal repair kit 34 installed on the car with the new sensor are shown in figure 2.

Regardless of the number of wires connected with the new sensor 38, installing it on the car is the same way. If n is the existence of the sensor three wire one hole 82 is empty. Because the holes 82 in the housing 70 are isolated from one another, the moisture that falls in an empty hole 82 through openings 90 and 114, can not penetrate into the other holes, which are the joints 56 three pairs of interconnected wires. It is obvious that the construction of the body 62 of the box 58 can be slightly changed by increasing or decreasing the number made holes 82. Such a change in the design of the housing 62 most likely will require a corresponding change to the design of the cover 66.

In the above description of the preferred variant of the invention, the proposed therein the connector used when replacing a car with a failing oxygen sensor in the exhaust gases, but it is clear that the solution proposed in the present invention can also be used to splice any electrical connections, protected from the weather. Thus, in particular, the present invention can be used for electrical connection of the products that you want to occasionally or periodically replaced. The present invention can also be used with success, and in the lengthening of the wires are exposed to corrosion under the influence of external conditions. The invention, for example, can be used to extend or replace the lighting wires, connect the shining vehicle with a trailer, especially for trailers with submerged connector, such as boats or other vessels.
