Guiding device for installing printed plate on electronic device, and guiding method of the same

Abstract

The invention discloses a guiding device for installing a printed plate on an electronic device, and a guiding method of the same. The guiding device is a guide pin, the guide pin is a cylinder divided into two parts, cross section areas of the two parts are different, and a bigger end is installed on a fixed structure; the top of the part with smaller cross section area on the guide pin is conic so as to be convenient to install, and the periphery of the part with smaller cross section area is provided with a knurl so as to be convenient for manual operation; and the end of the part with bigger cross section area of the guide pin is provided with a screw thread. For the guiding device with above special structures, before a contact pin enters into a socket, the fit clearance between an installation hole of the printed plate and the front end of the guide pin is larger, so that the printed plate can be conveniently moved; when the contact pin is close to a socket jack, the fit clearance is very small, thus, accurate location is realized, and the location of the contact pin and the socket jack is transformed into the location of the jack and the guide pin, so that damage on plug-in units caused by mistakes and inaccurate alignment is avoided, and work efficiency is improved.

Description

technical field [0001] The invention relates to a guiding device, in particular to a guiding device and a guiding method for installing printed boards on electronic equipment. Background technique [0002] At present, most of the electronic devices are multi-layer board space layout, and the electrical connection between the boards is mostly connected by plug-in plug-in. This kind of plug-in connection is widely used in electronic equipment. [0003] However, the pin-to-pin spacing on this type of pin is relatively small, generally 2 mm, so the precision requirements for straight insertion are high. This kind of plug-in is used between boards, and the operator cannot see the position of the plug-in during assembly, and it is in a state of blind installation. This kind of insertion method requires that the center of the pins should be aligned before entering the socket hole. At this time, the operator can only refer to the structural features next to it, such as fixing hole...

Problems solved by technology

However, this kind of rough reference assembly cannot meet the requirements of assembly accuracy. It is often found that the mounting hole is deviated or the side is not aligned when it is assembled to the mounting surface, so it is judged that the pins and socket holes are deviated, and the pins need to be pulled out and reassembled. Causes low work efficiency and wastes manpower and material resources
