Creature: receptacle connector type housing of insulating material with T-slots, in which the fixed electrical contacts, each consisting of two racks. One of the racks vyplnena as determined in the wide part of the groove and the other with a straight middle portion connecting the curved contact portion with the shank. Hours contact is not mechanically connected to one another. 2 C.p. f-crystals, 3 ill. The invention relates to electronic, electrical and electronics industry, and in particular to electrical connectors mounted on printed circuit boards.Known plug connector, consisting of two parts, one of which contains the pin, and the other case with a spring contact formed from multiple tselnovyazannymi elements representing two opposite sides of a coil, two shoulder connected by a connecting bridge, and the shank is designed for mounting and soldering it into the hole of the PCB .The drawbacks of such plug connectors are SL the arch of the housing for mounting the supporting rib protrusion for fixing the protruding surface of the spring contact, for example, by ultrasonic forging; limited technological capabilities, due to the fact that the connection pin is only possible on the one hand, a considerable amount of material on the contact element, as the contact has two opposite lateral orbits, two shoulder, connected by a long bridge; limited performance, due to the large size of the width of the contact due to the presence of the supporting rib protrusion for fixing the protruding surface of the spring contact.Also known plug connector consisting of a plug and socket . The outlet consists of a housing with a contact consisting of two opposite lateral turns, jumpers with limb for entering pin plug from the bottom of the contact and shank, one end of which has a protrusion for fixing the contact in the housing.The disadvantages of this electric connector is the limited operational characteristics caused by the large size of the width of the contact due to the presence of the limb for entering pin plug from the bottom of the contact; low wear resistance, due to the fact that the surface in contact with the pin, is formed watermusic surfaces of the contacts of the plug and socket; a significant flow of material into the contact sockets, as it has a complex shape and stamping ribbon produce large amounts of waste.The closest in technical essence to the invention is an electrical connector for vnutribruchnogo installation, consisting of a body, in the cavity of which is rigidly fixed electrical contact made in the form of two uprights connected by a bridge . One hour is rigidly fixed in the housing cavity and is made with a shank, and a jumper that connects the rack is bent so that the plane of the rack parallel. The narrow end of the rack bent from a wide stand at a certain angle.The disadvantages of this connector are the complexity of manufacturing electrical contact, which systembolagets of bronze ribbon on the scan, then the narrow part of the contacts, turn 180aboutto a wide stance, simultaneously tilting with a radius on the end for entry of the pin and bend the jumper to the formation of a semicircle for entering pin plug from the bottom of the contact; limited operational characteristics caused by the large size of the width of the contact due to the presence of the bent Perama for the possibility of breakdown between adjacent contacts; a significant flow of material into contact element due to the presence of the links connecting the two racks, and a low coefficient of use of the material, as it produces a lot of waste for stamping contacts from tape.The purpose of the invention is the enhanced operational capabilities by reducing the dimensions of the contact width and the reduction of material consumption for the manufacture of contact.This is achieved by the electrical connector containing receptacle body of insulating material with T-slots, each of which is mounted an electrical contact consisting of two pillars, one of which is made in the form determined in the wide part of the groove, and the other is made with a curved contact part that is installed in a narrow part of the groove, and a shank for mounting in a printed circuit Board, the second hour is made of a spring material with a straight middle part, passed through a hole in the casing and connecting the curved contact portion of the rack shaft. The curved part of the second rack can be performed flattened parallel to the width of the groove. Hour in the form of a strap can be performed with one-sided beveled ends. Racks do not have mechanicality operational capabilities by reducing the dimensions of the contact width and to reduce costs of material on the contacts. In the known device, the jumper connecting the two racks, curved and forms a semicircle for entering pin plug from the bottom of the contact, which increases the width of the contact, and limits the current load on the contacts because of the possibility of breakdown between adjacent contacts. In the proposed connector width of the contact is limited by the width of the body cavity. No jumper between racks of contact, the execution of one of the uprights of the wire spring material, and the other made in the form of strips, from any durable material (metal, durable plastic, and so on), can significantly reduce the cost of material for fabrication of the contact.Hour, made in the form of strips, protects from damage during repeated mating with the pins of the plug, the surface of the housing that allows the use of cheaper material for molding the housing and to increase the number of joints with pins in the plug.The curved part of the second rack is made of wire of spring material, if it is flattening parallel to the width of the groove, has great flexibility. Varying degrees of flattening the curved part allows you to adjust the degree of pressure to the terminal in the plug. Yes the hard joints with pin plugs without changing the material of the contact) is by giving different degrees of flattening the curved part of the rack. The size of the curve of the curved part and the degree of flattening are selected appropriate to ensure reliable contact with the terminal in the plug.Hour in the form of a strap can be performed with one-sided beveled ends, which facilitates insertion of the terminal in the plug in the contact hole, and also allows one of the known methods of attaching the rack - rolling beveled ends to the wall of the housing.
