Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment as required without making a contribution, but all the embodiments are protected by the patent law within the scope of the claims of the present invention.

The present embodiment relates to a plug convenient to assemble, as shown in fig. 1 and 2, including: an insulating housing 1 and two contact terminals 2. Because one side of the plug is provided with one limiting strip, two strip-shaped grooves 3 are formed in the two opposite side faces of the insulating shell 1 for realizing blind insertion with the socket. And an assembly hole 4 for the insertion of the contact terminal 2 is formed in the insulating shell 1.

Upper portion is provided with stopper 5 in 4 inner walls of pilot hole, and stopper 5 is cyclic annular, and stopper 5 and 1 integrated into one piece of insulating casing. A positioning block 6 is arranged between the wiring end 11 of the contact terminal 2 and the limiting block 5, and the positioning block 6 is used for abutting against the limiting block 5 to position the inserting position of the contact terminal 2. An elastic limiting structure is arranged between the matched terminal connecting end 12 of the contact terminal 2 and the limiting block 5, the elastic limiting structure moves relative to the contact terminal 2 under the action of the limiting block 5 so that the contact terminal 2 is inserted into the assembling hole 4 and resets under the action of self restoring force, and the end part of the elastic limiting structure is abutted against the limiting block 5 and matched with the positioning block 6 to limit the position of the contact terminal 2. The elastic limiting structure is an elastic sheet 7 with one end fixedly assembled on the contact terminal 2. Preferably, two spring pieces 7 are arranged and symmetrically arranged on two sides of the contact terminal 2.

As shown in fig. 3 and 6, the contact terminal 2 has a U-shaped cross section. The counterpart terminal connection end 12 of the contact terminal 2 comprises: the two elastic contact pieces 8 are bent towards the direction of the paired terminals to form a paired terminal accommodating cavity 9, the two elastic contact pieces 8 extend towards the opposite direction to form a horn-shaped socket 10 convenient for the butt joint of the paired terminals, and the mutual close positions of the two elastic contact pieces 8 are provided with protruding parts which are formed by the bending positions of the elastic contact pieces 8 and sunken towards the direction of the paired terminals.
