Specifically, the column pitch L2 of the straight pin 106 ranges from 1.0 mm to 1.2 mm, and the row pitch L3 of the straight pin 106 ranges from 1.2 mm to 1.3 mm.
[0030] In the figure, the middle part of the straight connector 1 is hollowed out to form a straight cavity 102, and the two sides of the straight shell 101 extend outward to form a hole connection table 103, and the hole connection table 103 is provided with a sunken table 104 near one side of the curved connector 2, a multi-hole plug 105 is installed in the straight cavity 102, a plurality of straight pins 106 are equidistantly installed inside the multi-hole plug 105, a bolt 107 is installed in the hole connection table 103, and a detachable nut 108 is sleeved at the end of the bolt 107. Specifically, the straight connector 1 is designed as a free end accessory to realize the locking connection of the board-to-board connector. The straight connector is designed with a sunken table on the mating surface, which can facilitate the insertion and separation of the plug and the socket, and the depth L1 of the sunken table 104 ranges from 0.5mm to 0.7mm.
[0031] It should be noted that since the printed board hole size and contact distance of the straight connector are relatively small, the user's printed board wiring is limited. A polytetrafluoroethylene film is added to the product to play an insulating role between the shell and the printed board, facilitating the user's printed board wiring. At the same time, a rotation-preventing detachable nut is designed to fix the connector on the printed board, facilitating the user to weld the contact pin, and when the product is mated, the nut is removed. In the figure, an insulating film 109 is provided between the hole connection table 103 and the printed board 3, and a contact washer 110 and an open spring washer 111 are provided between the head of the bolt 107 and the printed board 3.

The outer end of the vertical pipe 209 is located inside the vertical cavity 202 and is used to connect the straight pin 106, and the inner end of the vertical pipe 209 is connected with the horizontal pin 208.
[0033] In actual application, due to the requirements of user's space, it is necessary to increase the width of the product, and after the product is widened, the contact will also be correspondingly lengthened, which has a great influence on the weight of the product. Widening the shell leads to an increase in the weight of the product, which exceeds the user's requirement that the weight of the connector should not exceed the standard, therefore, the widened part of the shell is designed to be hollow, specifically, the outer contour length L4 of the curved connector 2 ranges from 18mm to 24mm.
[0034] The structure can meet the requirements of printed board welding and can be used as a free end form by improving the shell shape and adding the nut, the sink, the weight reduction groove and the like, has the advantages of miniaturization and light weight, can meet the requirements of the miniaturization of the whole machine and users, and conforms to the development trend of modern weapons and equipment.
