RU1781749C - Socket with protective contact - Google Patents

Abstract

Usage: in the electrical industry, in particular as a household outlet. SUMMARY OF THE INVENTION: a plug socket comprises plug sockets, fittings with a groove between the plug sockets for receiving a protective contact bracket. The fittings are made detachable, and the groove along the length on both sides has undercuts. The width of the groove is equal to the width of the protective element, 2 il.

Description

The invention relates to the electrical industry, in particular to household outlets. In the USSR, plug sockets with a protective volume are made of various designs. The protective contact is attached to the housing of the socket with screws, which complicates their assembly.

An object of the invention is to provide a socket outlet with an earthing contact, which is technologically advanced to manufacture and easy to assemble.

A well-known socket with grounding, containing a pair of spring coded contact sockets and a grounded spring contact socket. All slots are inserted inside a recess formed within the housing.

Contacts are formed on both end portions of the sockets for connection to the contact pin. Contacts are formed on the grounded spring contact socket for connection to a grounded contact pin and a pair of terminals located opposite each other. When installing the sockets in the recess of the housing, the terminals are inserted 8

respective recesses and are secured with clamps.

The disadvantage of such a socket is that the device is characterized by a complex design of the housing, contact sockets. These parts are not technologically advanced to manufacture.

The closest technical solution to the same problem with regard to the achieved positive effect and technical essence is a socket with a protective contact containing a base, in which there are open compartments in the insertion direction for accepting the Stack of jack sockets and a connecting terminal and also a recess between the plugs sockets, which are provided with a hole in the middle for receiving a bracket with protective contacts. The bracket with protective contacts is held on both sides relative to its middle by two V-clamps that enclose the intermediate jumper of the bracket with protective contacts

The disadvantage of such a socket is that the socket has many structural parts for attaching a bracket with a grounding

contact to the base, which increases the complexity of manufacturing the outlet.

The purpose of the invention is to simplify the design and reduce the complexity of manufacturing a socket with a grounding contact.

This goal is achieved by the fact that in the outlet, including the plug sockets, the fittings with a groove between the plug sockets for receiving the protective contact bracket, the fittings are axially detachable, perpendicular to the groove, and provided with a ring for fixing the two halves of the fittings, while the groove is along the length of both sides are made with undercuts, the width of the groove with undercuts being equal to the width of the bracket.

Compared with the closest similar solution, the claimed technical solution has the following distinctive features: the reinforcement is split along the axis, perpendicular to the groove and provided with a ring for fixing the halves of the reinforcement, the groove along the entire length on both sides is made with undercuts, the groove width with undercuts equal to the width of the bracket.

When implementing the invention, the design of the outlet is simplified and the manufacturing time is reduced due to detachable reinforcement along the axis perpendicular to the groove having an undercuts and rings along the entire length of both sides, allowing grounding contact to be established in the outlet groove and assembly of the outlet without the use of co-tools and devices , which makes the assembly of the outlet simple and technological.

The authors conducted an additional search for distinctive essential features.

Sockets are known which include split fittings and having rings for attaching two halves of the fittings.

However, all of these socket outlets do not have an earthing contact in their design, having the fittings made only for the convenience of installing the socket, the socket in the proposed socket is perpendicular to the groove in order to install the bracket of the earthing contact in its undercut. Also, the ring provided in the construction of the socket, used to connect the two halves of the valve, has a thread on the inner surface, i.e. the two halves are joined by screwing the ring.

In the proposed design, the connection of two reinforcing elements is carried out using a ring that is tensioned

two halves all the way. This connection provides a secure fit at the lowest cost when comparing a threaded ring.

In the known design of the socket, the connection of the two halves of the reinforcement is made using a half ring made of spring material. The manufacture of such a ring is more difficult than in the proposed embodiment.

Figure 1 in a section along the axis of the plug sockets; Fig. 2 shows a socket outlet in section along the axis of the bracket of the grounding contact.

5, the socket consists of a housing 1 directed to the reinforcement 2 with a stop 3 in the connecting part 4, consisting of two halves, in the sockets 5 of which there are contact elements 6 mounted on the studs 7 of one of the halves, the reinforcement is perpendicular to the line of the connector both halves of the groove 8 with undercuts 9, with the grounding contact 10 installed in them, made in the form

5 staples. For fixing the two halves of the reinforcement 2, a ring 11 is provided in the connecting part 4.

The portable outlet is assembled as follows.

0 In one of the halves of the reinforcement 2, the contact elements 6 are put on the studs 7, in the undercut 9 of the groove 8 located in one half of the reinforcement, half of the grounding contact 10 is inserted. Then on

5 of the stud 7, a second half of the reinforcement 2 is worn, with the second half of the grounding contact 10 entering the undercut 9 of the groove 8 of this half of the reinforcement.

Compared to the prototype of the invention

A portable socket has the following advantages: it provides ease of assembly of the socket without the use of tools and fixtures; it provides the manufacture of socket parts in automatic and semi-automatic modes.
