Wherein: 1. the socket comprises a supporting plate, a base plate, a lifting rod, a plug hole, a cushion block, a side plate, a connecting rod, a screw, a guide pin, a pick-and-place groove, a base plate, a reset bolt, a reset spring and a plug-in PCB, and a socket PCB.

Detailed Description

The utility model will be further described with reference to the accompanying drawings and specific examples.

The auxiliary pulling device for the inter-board connector shown in fig. 1 to 6 comprises a supporting plate 1, a base plate 2 and a pulling rod 3, wherein a groove for placing a PCB 14 with a plug is formed in the supporting plate, a plug hole 4 matched with the PCB with the plug is formed in the groove, a plurality of cushion blocks 5 are arranged at the edge of the groove, the pulling rod comprises two side plates 6 and a connecting rod 7 in a Z-shaped structure, one ends of the two side plates 6 are connected through the connecting rod 7, the middle of the two side plates is rotatably connected to the side face of the base plate 2, the other ends of the two side plates extend into the lower surface of the supporting plate 1, threaded holes are formed in the base plate 2, the positions of the threaded holes correspond to the positions of through holes in a PCB with a socket, the PCB with the socket are fixedly connected with the base plate 2 through screws 8, guide pins 9 are arranged on the base plate 2, and guide pin holes matched with the guide pins 9 are formed in the supporting plate 1.

In the above technical solution, the supporting plate 1 is provided with a picking and placing groove 10, and the picking and placing groove 10 is disposed near the plug hole 4. The picking and placing groove 10 can be used for placing fingers when picking and placing the PCB with the plug, so that the problem that the gap between the PCB with the plug and the groove is too small to be conveniently taken out is avoided.

In the above technical solution, one side of the plug hole 4 is provided with a strip-shaped backing plate 11, and the side surface of the backing plate 11 is provided with a reinforcing rib. The pad 11 and the cushion block 5 are used for evenly spreading the force applied to the PCB 14 with the plug, and the PCB 14 with the plug is not damaged in the process of pulling out.
