Description

a connector

technical field

The utility model relates to a connector, in particular to a connector with an anti-pulling device, which can produce a hooking effect when plugged with another connector to prevent accidental disengagement.

Background technique

When the computer signal lines are connected, the connectors at the plug ends of the signal lines are mated with each other. Meanwhile, in order to prevent the mating ends of the connectors from being disengaged improperly, an anti-pullout device is provided on the connectors, so that the two connectors can produce a buckling effect when they are mated. For example, the structural improvement of the hook body of the electrical connector announced by my country Announcement No. 433618 is disclosed. The connector disclosed in said patent has a hook body to resist pulling out. The hook body is introduced into the dovetail groove of the connector housing to be connected with the connector. In addition, a metal cover is fixed on the housing to prevent the hook body from falling off from the side.

The main purpose of the metal cover in the aforementioned patent is to protect the function of the housing and prevent the hook body from falling off from the side. However, in view of the metal cover arrangement structure, the metal cover can prevent the hook body from detaching from the front. However, the hook body can move in the dovetail groove, so that the positioning effect is poor, and the position deviation is prone to occur.
