Problems solved by technology

For plugs and sockets with limit pins, the limit pins can correct them when there is a small deviation in the insertion; but for plugs and sockets without limit pins, it is easy to cause misalignment of the pins and sockets during the insertion, which affects Signal transmission, in severe cases, it will cause the pins to break

Embodiment Construction

[0020] Electronic equipment often uses plugs and sockets to realize signal transmission between two printed boards. See figure 1 . The structural unit where the plug socket is located can be simplified as a sub-board combination and a motherboard combination.

[0021] For sub-board composition see figure 2 , consists of a sub-board frame, a sub-board printed board, and a sub-board plug. The daughterboard plug is soldered to the daughterboard printed board, and then fixed together on the daughterboard frame.

[0022] Motherboard composition see image 3 , consists of a left side board, a right side board, a bottom board, a motherboard printed board, and a motherboard socket. The left panel, the right panel and the bottom panel together form a structural frame. The motherboard socket is welded on the motherboard printed board, and then fixed together on the bottom plate.

[0023] Daughter board combination via Figure 4 Insert it from the grooves on the left side board a...

Abstract

The invention discloses a structure design method for improving plug and socket plugging precision and belongs to the structure design field. For the problem of misplacement of a plug and a socket which are fixedly arranged on different printed boards during mutual plugging, three measures of daughter printed board limitation, mother printed board limitation, and daughter board frame and bottom board limitation are provided. Through the comprehensive application of the three measures, installation precision of the plug and socket without limitation pins is ensured, thereby preventing the problems of poor contact due to misplacement of the plug and the socket or breaking of contact pins due to press and the like, and improving design quality of electronic equipment.

Description

technical field [0001] The invention relates to a plug and socket without a limit pin, in particular to a plug and socket respectively fixed on different printed boards, which uses a structural design method to improve the mating precision of the plug and socket, and belongs to the field of structural design. Background technique [0002] In the electrical connection of engineering applications, plugs and sockets are common signal transmission methods. Generally, when transmitting signals between two printed boards, using a plug and socket saves space and improves efficiency compared to welding wires. For plugs and sockets with limit pins, the limit pins can correct them when there is a small deviation in the insertion; but for plugs and sockets without limit pins, it is easy to cause misalignment of the pins and sockets during the insertion, which affects In severe cases, the signal transmission will cause the pins to break. Contents of the invention [0003] The presen...
