Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the prior art, as shown in fig. 1, a spot welding copper sheet is generally used for realizing conduction of a terminal shell, and a spot welding spot needs a large area, which is not beneficial to reducing the volume of the terminal shell, and a spot welding process is complex, which results in high cost, and is not beneficial to reducing production cost.

In view of the above, referring to fig. 2 to fig. 4, the present invention provides a terminal housing conduction structure, including: the shell 1 is provided with a blind hole 3 at a conduction part 2 of the shell 1; with blind hole 3 complex copper post 5, this copper post 5 includes the screens structure 51 that sets up along the circumference of copper post 5 to when copper post 5 assembles with blind hole 3, screens structure 51 cooperates with blind hole 3 in order to fix copper post 5.

Above-mentioned terminal housing conduction structure, 2 the position that switches on at casing 1 sets up blind hole 3, and utilize screens structure 51 and the cooperation of blind hole 3 along self circumference setting, when copper post 5 assembles with blind hole 3, utilize the press to press copper post 5 to impress copper post 5 in blind hole 3, it is crowded tightly to interfere through screens structure 51 between copper post 5 and the blind hole 3, because the material of casing 1 is the alloy, copper post 5's fixed effect has not only been guaranteed, and the effect that switches on has been guaranteed. In addition, in the prior art, when the copper sheet is subjected to spot welding, the design size of the copper sheet is generally 3.2 x 2.2mm, the diameter of the blind hole 3 in the application is about 1.5mm, the occupied space is much smaller than that in the prior art, the purpose of reducing the volume of a terminal can be well achieved, meanwhile, the purpose of conducting is achieved through the copper column 5, the cost is also reduced compared with a spot welding process, and the operation is easier compared with a complex process of spot welding, and the product yield is also improved.
