A multi-point long-pin connector that is convenient to disassemble and assemble and disassemble method thereof

Abstract

The invention relates to a multi-point long-pin connector which is convenient for disassembly and assembly and a disassembly method thereof, comprising a plurality of connector units and lifting screws, wherein among any adjacent upper and lower connector units, the upper The pin part exposed under the printed board in the unit cooperates with the jack part welded above the printed board in the lower connector unit. Two guide pins are arranged on the shell of the upper connector unit, and the lower connector unit There are two guide holes matched with the guide pins on the housing. In addition, there are threaded holes on the four corners of the upper connector unit housing. When the upper and lower connector units are separated, the lifting screws are inserted into the threaded holes. In the middle, and make the end of the pulling screw withstand the concave surface of the lower connector unit housing, the present invention adds guiding structural elements in the structural design to ensure the precise positioning of the connector during assembly, greatly improving the manufacturability of assembly, and even Realize blind insertion, and realize reliable, stable, efficient and low-cost equipment assembly.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment structure design, and relates to a multi-point long-pin connector which is convenient for disassembly and assembly and a disassembly method thereof. Background technique [0002] Due to the requirement of small size and multiple functions for electronic equipment in some fields at present. Therefore, some electronic devices are designed by stacking multiple circuit boards. In order to realize the electrical connection between adjacent circuit boards, in-line multi-point long-pin connectors are often used. In the past, the assembly of this kind of equipment was generally carried out by visual inspection, and the mating of the connectors was realized by visual inspection and hand feeling. Because the operating space was too small, the visual inspection was not enough, and blind insertion was actually formed. See Figure 5 , there will inevitably be positioning errors, and it is difficu...

Problems solved by technology

In the past, the assembly of this kind of equipment was generally carried out by visual inspection, and the mating of the connectors was realized by visual inspection and hand feeling. Because the operating space was too small, the visual inspection was not enough, and blind insertion was actually formed. See Figure 5 , there will inevitably be positioning errors, and it is difficult to achieve accurate alignment of the pins and sockets by visual inspection, which will cause damage to the pins, affect electrical performance, and even cause damage to the pins or even burn out the circuit; when disassembled, It is to insert the special tool between the corresponding bosses on the outside of the two housings where the circuit board is installed, see Image 6 , tilt the shell open, and then pull out the two connectors by hand

Sometimes the pins are deformed, damaged, or even scrapped due to eccentric force

At the same time, in the process of prying the shell, the special tool will damage the paint film on the outer surface of the product, affecting the appearance and anti-corrosion effect of the shell
