Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Example 1:

referring to fig. 1 to 6, the present invention discloses a wiring structure, which includes a plug 1 and a socket 2 for receiving and fixing the plug 1; the receptacle 2 has a plug receptacle 20, a locking element engaging member being provided in the plug receptacle 20;

the plug 1 comprises a front head part 10 which is slidably inserted into a plug jack 20 of the socket 2 and a main body part 11 which is connected with the front head part 10, wherein a knob 3 is rotatably arranged on the main body part 11, a convex wall 30 which extends into the plug jack 20 is arranged on the knob 3, and a locking element is arranged on the convex wall 30;

when the plug 1 is inserted into the receptacle 2, the locking member engaging piece is engaged by the locking member so that it is fixed, and the locking member engaging piece can be separated by rotating the knob 3 so that the fixed state of the plug 1 and the receptacle 2 is released.

Wherein, an elastic part 4 which can push the knob to rotate in the circumferential direction is also arranged on the main body part 11, and the elastic part 4 pushes the knob 3 to enable the locking element to be in an engagement position with the locking element engagement piece. Specifically, the elastic member 4 is a coil spring, and an annular groove 110 that receives the coil spring is provided on the main body portion 11. The elastic part 4 is arranged to enable the elastic part 4 to exert pushing force to enable the locking element on the plug to be maintained in the locking element joint after the plug is inserted into the socket, and at the moment, when the plug receives large external force, the fixed state of the plug and the socket cannot be easily released due to elastic pushing of the elastic part 4.

The knob 3 includes a sleeve member 31, and a button 32 for applying a manual force is protruded on a surface of the sleeve member 31. The surface of the button 32 has a first concave arc surface, and the side of the sleeve part opposite to the button 32 is provided with a second concave arc surface concave towards the button 32. When the structure is operated, a user can conveniently clamp two fingers on the first cambered surface and the second cambered surface and apply the pushing force of the rotary knob 3.

The protruding wall 30 has a notch 33, and two ribs 12 are disposed at intervals in the circumferential direction of the front end portion 10, and the ribs 12 are located in the notch 33. The rotation angle of the knob 3 can be limited by the cooperation of the rib 12 and the groove wall of the notch groove 33, and the elastic member can be prevented from being damaged when the rotation angle is too large.

As a specific example of a locking element and a locking element engaging member, the locking element is provided as a protrusion protruding towards the protrusion wall and the corresponding locking element engaging member is a groove matching the shape of the protrusion. Of course, the locking element and the locking element engaging member in the present application may also be configured as an existing common locking structure, and it only needs to be satisfied that the above-mentioned locking mechanism can achieve locking and unlocking when the knob is rotated, and the specific types of the locking element and the locking element engaging member that may be used are not described in detail in the present application.

Example 2:

in this embodiment, a ring of convex rings 21 is provided on the end surface of the plug insertion hole 20, as compared with embodiment 1. The convex ring 21 enables the lower end face of the knob 3 to be in contact with the end face of the convex ring 21 when the knob 3 is rotated, and abrasion caused by direct contact friction between the lower end face of the knob 3 and the end face of the socket can be avoided.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
