Detailed Description

In order that those skilled in the art will better understand the present utility model, a technical solution in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.

As shown in fig. 1-4, the multi-pin collecting and inserting electric connector comprises an inserting plate 1 and inserting pins 7, wherein side plates 2 are arranged on the periphery of the upper surface of the inserting plate 1, and a pouring cavity 3 for pouring sealing glue 4 is formed by the side plates 2;

the inserting plate 1 is provided with a plurality of inserting holes 5, the upper end of the inserting hole 5 is provided with an outward-expansion inserting hole 6, and the outward-expansion inserting hole 6 can avoid the problem that the inserting pin cannot be smoothly inserted into the inserting hole 5 when the inserting pin 7 is slightly inclined; the jack 5 is respectively provided with a contact pin 7, the contact pin 7 is used for being connected with the circuit board 12, the lower section of the contact pin 7 is provided with a clamping groove 8, and when the contact pin 7 is welded with the circuit board 12, soldering tin can flow into the clamping groove 8, so that the connection between the contact pin 7 and the circuit board 12 is firmer.

Further, supporting legs 9 are uniformly arranged on the periphery of the lower surface of the inserting plate 1, and the height of each supporting leg 9 is smaller than the height of the lower end of each inserting pin 7 protruding out of the inserting plate 1.

Further, the pins 7 are subjected to surface tinning treatment, and the pins 7 subjected to tinning treatment are convenient to weld with the circuit board 12.

Further, the upper and lower ends of the pin 7 are respectively provided with a taper plug 10, and the taper plugs 10 are convenient to be inserted into the jack 5 and the link holes on the circuit board 12.
