[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] The same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] As shown in the figure, a short-circuit cap with a long service life includes a shell 1, the bottom of the shell 1 is recessed downward to form a groove, a connecting plate 2 is fixedly connected in the groove, the surface of the connecting plate 2 is recessed downward to form a first mounting groove and a second mounting groove, a first connector 3 is arranged in the first mounting groove, a second connector 4 is arranged in the second mounting groove, and an injection molding plate 5 is formed in the first mounting groove and the second mounting groove by injection molding.

[0022] By fixing the first connector 3 and the second connector 4 in the first installation groove and the second installation groove, the stability of the first connector 3 and the second connector 4 after installation is ensured, and the service life thereof is improved.

[0023] The first plug connector 3 includes a first bottom plate 6 placed at the bottom of the first mounting groove, a first through hole 7 is provided on the surface of the first bottom plate 6, and a first plug board 8 is provided on the surface of the first bottom plate 6 to extend vertically and extend from the surface of the injection molding plate 5. The second plug connector 4 includes a second bottom plate 9 placed at the bottom of the second mounting groove, a second through hole 10 is provided on the surface of the second bottom plate 9, and second plug boards 11 are provided on both sides of the surface of the second bottom plate 9 to extend vertically and extend from the surface of the injection molding plate 5. The first bottom plate 6 and the second bottom plate 9 are used to increase the contact area between the first bottom plate 6 and the injection molding plate 5, and further improve its stability after the injection molding is completed.

[0024] Two connecting columns 12 corresponding to the first through hole 7 and the second through hole 10 are arranged at the bottom of the groove, and screw holes 13 are arranged at the top of the connecting column 12. Through holes 14 corresponding to the two screw holes 13 are arranged at the bottom of the first installation groove and the second installation groove. Before the injection molding work, bolts are arranged in the first through hole 7 and the second through hole 10, and the first plug-in component 3 and the second plug-in component 4 are connected to other electronic components by electrical signals through bolts.
