Description

Self-locking anti-drop electric connector assembly

Technical field

The utility model relates to electric connector technology, particularly relates to a kind of technology of self-locking anti-drop electric connector assembly.

Background technology

Existing numerous standard electrical plug, socket are all fairly simple, and after plug insertion socket, easy accidental, makes electric equipment accident power-off.

Summary of the invention

For the defect existed in above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of plug of avoiding from the self-locking anti-drop electric connector assembly of accidental socket.

In order to solve the problems of the technologies described above, a kind of self-locking anti-drop electric connector assembly provided by the utility model, comprise plug and socket, it is characterized in that: the outer peripheral face of described plug has the radial boss protruded, and on described socket, symmetry is fixed with two grabs;

Described grab comprises being fixed on socket has the flexible neck of hook, and the fastener be fixed on the neck of hook, the installation position of two grabs matches with plug, after making plug insertion socket, the neck of hook of two grabs lays respectively at the both sides of plug, and the fastener of two grabs compresses the boss of plug outer peripheral face respectively along plug direction of insertion.

The self-locking anti-drop electric connector assembly that the utility model provides, by being fixed on socket having coordinating of flexible grab and the step on plug, can be automatically locked on socket by plug, plug can be avoided from accidental socket.

Embodiment

Illustrate below in conjunction with accompanying drawing and embodiment of the present utility model is described in further detail; but the present embodiment is not limited to the utility model; every employing analog structure of the present utility model and similar change thereof; protection range of the present utility model all should be listed in, the pause mark in the utility model all represent and relation.

As shown in Figure 1-Figure 3, a kind of self-locking anti-drop electric connector assembly that the utility model first embodiment provides, comprise plug 1 and socket 2, it is characterized in that: the outer peripheral face of described plug 1 has the radial boss 11 protruded, and on described socket 2, symmetry is fixed with each grab 3 around;

Described grab 3 comprises being fixed on socket 2 has the flexible neck of hook 31, and the fastener 32 be fixed on the neck of hook 31, the installation position of two grabs 3 matches with plug 1, after making plug 1 insert socket 2, the neck of hook 32 of two grabs lays respectively at the left and right sides of plug 1, and the fastener 32 of two grabs compresses the boss 11 of plug outer peripheral face respectively along plug direction of insertion.

The principle of the utility model first embodiment is as follows:

When plug 1 is inserted socket 2, the fastener 32 of plug 1 meeting ejection two grabs, make the neck of hook 32 outwards elastic deformation of two grabs, after the fastener 32 of two grabs is by ejection to the position of not interfering plug plug, plug 1 can insert socket 2 smoothly, after plug 1 inserts socket 2, two grabs can return back to initial condition under elastic reaction, the fastener 32 of two grabs also returns back to initial position thereupon, thus compress the boss 11 of plug outer peripheral face along plug direction of insertion, thus plug latch is fixed on socket 2;

When needing plug 1 to pull away socket 2, the fastener 32 of artificial force ejection two grabs, make the neck of hook 32 outwards elastic deformation of two grabs, after the fastener 32 of two grabs is by ejection to the position of not interfering plug plug, first plug 1 is pulled up from socket 2, fastener 32, two grabs unclamping two grabs again can return back to initial condition under elastic reaction.

As shown in Figure 4, the difference of the utility model second embodiment and the first embodiment is: the both sides, front and back being fixed on socket 202 of two grab 203 symmetries in the second embodiment.
