(57) Abstract:

The invention relates to electrical engineering, in particular to a device mounting contact elements and conclusions in the case of devices or apparatus. The attachment of the contact element consisting of narashima United contact pin and the connecting contact, includes a housing with a through hole and an additional locking element in the form of arcuate spring with a hole in the center that is installed in expansion between the housing and the horizontal plane of the connecting contact. The housing bore is made with a notch at one end, which is equipped with spring its convex part, and nests on the other end, in which are mounted the contact pin by means of its lateral protrusions. 1 C.p. f-crystals, 1 Il.

The invention relates to the field of electrical engineering and, in particular to a device mounting contact elements and conclusions in the body of the instrument or other apparatus.

The known attachment of the contact element that contains the split housing with two retaining tabs and slot in which is mounted a contact element [1] . The disadvantage of this site is its limited application, including the of conduct.

The closest to the technical essence and the achieved result is the attachment of a contact element used in the instrument plug EP 2000 [2]. In this device, the contact element is designed as a contact pin and the connecting contact is riveted together. Pin is for connecting an external cord through a contact socket of the instrument outlet, reinforcing the connecting cord of the electrical device, and connecting the contact for connecting the internal wiring of the device. This contact element is pressed in case of an instrument plug when it is pressed.

The disadvantage of such a control node is the high complexity of manufacture, a large number of marriage, used small capacity (mnogodelnosti) of the mold. In addition, it is not safe installation operation of the contact elements in an open heated mold.

The objective of the invention is to reduce the complexity of manufacturing the contact node, reduce scrap, and improve safety of manufacture by eliminating the process of pressing the contact element in the housing with its crimp.

This task is achieved by CTI body with a through hole, which has a contact pin is further provided with a locking element made in the form of arcuate spring with a hole in the center, established in expansion between the housing and the horizontal plane of the connecting contact and the housing bore is made with a notch at one end, which is equipped with spring convex part, and nests on the other side, which has a contact pin through its lateral protrusions. In addition, at the end of the contact pin is made an additional protrusion which, when the Assembly is placed in the hole of the horizontal plane of the connecting contact, and then produce rasklapanje, forming a single contact element.

This construction allows the Assembly process to strictly fix the connecting contact and the contact pin relative to each other and relative to the housing and by means of a spring to create a secure fastening. While the complexity of manufacturing the contact node is low, as is done by mechanical Assembly. When large production volumes are possible automation of the manufacturing process.

The drawing shows the attachment of the contact element is CA 2 is made with a recess 5 at one end and with the slots 6 - on the other end. Contact element 1 consists of narashima United contact pin 7 and the coupling pin 8, and pin 7 is made with lateral projections 9 and the end protrusion 10, and the connecting pin 8 is made of l-shaped, i.e. has a horizontal plane 11, which made the hole 12. Pin 7 is installed in the through-hole 3 of the housing 2 and is fixed on one side of the housing 2 by means of lateral projections 9, installed in slots 6 holes 3. On the other side of the housing 2 pin 7 is located in the hole of the spring 4 inserted in the recess 5 of the hole 3 based on its convex part of expansion between the housing 2 and the horizontal plane 11 of the connecting pin 8, while the end of the protrusion 10 of the contact pin 7 narashima fixed in the hole 12 a horizontal plane 11 of the connecting pin 8 by the fragment.

During the production of this contact of the first node in the hole 3 of the housing 2 set pin 7 and fix it by means of lateral projections 9, having them in the sockets 6 holes 3. On the other end of the contact pin 7 put the spring 4 and set it into the recess 5 of the hole 3 based on convex citom end of the protrusion 10 of the contact pin 7 into the hole 12 a horizontal plane 11 of the connecting pin 8. Then produce rasklapanje end of the protrusion 10 of the contact pin 7 in the hole of the connecting pin 8, forming a one-piece contact element 1.

Thus, the complexity of manufacturing, we offer the contact node is low, as is done mechanically. This ensures high reliability of the mounting of the contact element through the use of the locking spring and a number of indentations, projections, nests on the contact element and the housing.

The use of the proposed solutions for two or more contact elements allows to manufacture various instrument plug and bushing clamps for electrical devices and equipment that meet the requirements of the international IEC standards.

1. The attachment of the contact element consisting of narashima United contact pin and the connecting contact, comprising a housing with a through hole, characterized in that it further provided with a locking element made in the form of arcuate spring with a hole in the center that is installed in expansion between the housing and the horizontal plane of the connecting contact of the contact element.

2. Site under item 1, the convex part, and with nests on the other side, which has a contact pin of the contact element by means of its lateral protrusions.
