Abstract

The utility model relates to an anti-loosening mechanism of an electric connector socket, comprising an insurance hook assembly (3) and a draw hook assembly (4). The insurance hook assembly (3) is connected with a draw hook connecting shaft (11) in the draw hook assembly (4) through an insurance hook (6) in the insurance hook assembly (3). The utility model has the advantages of simple structure, convenient operation and safe and reliable connection. When a connector plug is plugged in a socket, the anti-loosening mechanism on the connector socket locks a rocker so as to ensure that the plug and the socket can not loosen during the use process of the connector.

Description

The electric connector socket escapement

Technical field

The utility model is a kind of escapement that is used on the electric connector socket, belongs to technical field of electric connectors.

Background technology

At present, the transferring electric power of using always on the railway and the electric connector of signal are realized locking function by rocker arm body, thisly cross the dead point by rocker arm body and reach the connector of locking effect in actual mechanical process, not locked phenomenon after misoperation may take place causing connector to plug together, thereby the contact that causes connector is unreliable even get loose, and causes big accident and loss.

Summary of the invention

The purpose of this utility model is intended to overcome prior art in actual mechanical process, not locked phenomenon after meeting generation misoperation causes connector to plug together, cause the unreliable even defective such as get loose of the contact of connector, propose a kind ofly to plug together when putting in place when connector plug and socket, pin rocking arm by the escapement on the socket, guarantee the electric connector socket escapement that plugs and sockets does not get loose in the connector use.

Technical solution of the present utility model: it is characterized in that forming by auxiliary catch assembly and drag hook assembly.Wherein auxiliary catch in the auxiliary catch assembly and the drag hook connecting axle in the drag hook assembly join.

Advantage of the present utility model: simple in structure, easy and simple to handle, attachment security is reliable.When connector plug and socket plug together when putting in place, pin rocking arm by the escapement on the connector body, guarantee that plugs and sockets does not get loose in the connector use.

Embodiment

The contrast accompanying drawing, its structure is made up of auxiliary catch assembly 3 and drag hook assembly 4, and wherein the drag hook connecting axle 11 in auxiliary catch in the auxiliary catch assembly 36 and the drag hook assembly 4 joins.

Described auxiliary catch assembly 3 comprises big connecting plate 10, auxiliary catch 6, auxiliary catch alignment pin 7, auxiliary catch rotating shaft 8 and torsion spring 9, square auxiliary catch 6 wherein is installed in the auxiliary catch rotating shaft 8, torsion spring 9 is installed in the auxiliary catch rotating shaft 8, one end of its torsion spring 9 is fixed on the big connecting plate 10, and the other end is close to the side of square auxiliary catch 6.Auxiliary catch 6 lower ends be 40 ° of inclined-planes and with auxiliary catch lower surface external arc rounding off.Determine the final position of auxiliary catch 6 at the insure installed inside auxiliary catch alignment pin 7 of hook 6 of big connecting plate 10.

Described drag hook assembly 4 comprises drag hook connecting axle 11, drag hook 12, and wherein drag hook connecting axle 11 is installed on the drag hook 12.When connector plug 2 and connector body 1 plug together put in place after, auxiliary catch 6 hooks drag hook connecting axle 11 automatically, thereby pins Rocker arm 5.

When connector plug is connected with socket, rotating the simultaneously big connecting plate 10 rotation drive drag hooks 12 of Rocker arm 5 axially moves along guide rod 13, the roundlet side face of the drag hook connecting axle 11 on the drag hook 12 is close on the auxiliary catch that 40 ° of inclined-planes slide and the active force that overcomes torsion spring 9 enters the auxiliary catch concave surface, and auxiliary catch 6 pins drag hook connecting axle 11.When need are thrown off connector plug and socket, on auxiliary catch 6, apply certain active force along direction shown in Figure 2, after auxiliary catch 6 turned an angle, drag hook connecting axle 11 got final product release, upwards rotated Rocker arm 5, and this moment, plug can separate from socket.

Claims
