[0021] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0022] like Figure 1-Figure 4 As shown, a novel local plating jig for micro-pitch connector pins provided in the present embodiment comprises a main frame 1, on which a plurality of groups of mounting holes 2 are evenly arranged, through which the pins enter the main frame 1, and a stabilizing component 3 is installed in each group of mounting holes 2, wherein the stabilizing component 3 comprises a stabilizing frame 301 located in the middle of the mounting holes 2, the stabilizing frame 301 can clamp and stabilize the pins, a guide rod 302 is installed at the lower outer side of the stabilizing frame 301, the guide rod 302 can guide and limit the movement of the stabilizing frame 301, the guide rod 302 is a telescopic structure, and a telescopic spring 303 is installed at the outer side of the guide rod 302, the reaction force generated by the contraction of the telescopic spring 303 acts in the stabilizing frame 301, the pins are clamped and fastened by the stabilizing frame 301, and the two ends of the telescopic spring 303 are respectively fixedly connected to the main frame 1 and the stabilizing frame 301, each group of stabilizing frames 301 is a symmetrical detachable structure, and the cross-section of the stabilizing frame 301 is a funnel-shaped structure.

[0023] like Figure 1-Figure 3 As shown, the mounting hole 2 passes through the main frame 1 , and the stabilizing component 3 and the mounting hole 2 are located at the same axis, so that the pin can enter the stabilizing component 3 when entering the mounting hole 2 .

[0024] like Figure 1-Figure 3 As shown, a middle plate 4 is installed at the bottom of the main frame 1, and empty slots are opened on the middle plate 4 corresponding to the mounting holes 2, and limiting pads 5 are installed in each group of empty slots to facilitate the bottom end of the pin to enter the middle plate 4 through the mounting hole 2, and the pin is limited by the limiting pads 5 in the middle plate 4.

[0025] like Figure 1-Figure 3 As shown, a bottom plate 6 is fixed below the middle plate 4 , and through holes 7 are provided on the bottom plate 6 corresponding to the limit pads 5 , so that the bottom end of the pin can pass through the through holes 7 and penetrate the bottom plate 6 .

[0026] like Figure 1-Figure 3 As shown, the inner diameter of the limiting pad 5 is smaller than the inner diameter of the mounting hole 2, and the inner diameter of the through hole 7 is the same as the inner diameter of the limiting pad 5, thereby ensuring the verticality of the installation of the pin and preventing the pin from tilting.
