Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more specifically to the technical field of a magnetic attraction test connector. Background Art

[0002] All electronic devices are inseparable from the PCB board. From small electronic watches, calculators, and general-purpose computers to large computers, communication electronic devices, and military weapon systems, as long as there are electronic components such as integrated circuits, the electrical interconnection between them uses the PCB board. In addition to fixing various small parts, it provides mechanical support for the fixed assembly of various electronic components such as integrated circuits, realizes the wiring and electrical connection or electrical insulation between various electronic components such as integrated circuits, and provides the required electrical characteristics, such as characteristic impedance, etc. At the same time, it provides a solder mask pattern for automatic soldering; it provides identification characters and graphics for component insertion, inspection, and repair. As electronic devices become more and more complex, more and more parts are needed, and the circuits and parts on the PCB board are becoming more and more dense.

[0003] There are various connectors on the PCB board for the debugging interface of the PCB board. The following technologies are disclosed in the existing patents:

[0004] The patent with the publication number CN112448192A and the patent name "Electrical Connector and Its Assembly" discloses the following content: It includes an electrical connector and a cover plate. The electrical connector includes an insulating body and conductive terminals. The cover plate is buckled on the insulating body. The cover plate has two first side walls, and the insulating body has a first side surface; the insulating body is provided with a pair of buckling ports formed by inward depression from its first side surface. The first side wall is provided with an operating part and a pair of buckling arms. The operating part includes a depressed part and a lifting part located above the depressed part. The buckling arm includes an elastic arm formed by splitting from the first side wall and a buckling head protruding downward at the end of the elastic arm. The buckling head is received and buckled in the buckling port. The operating part and the buckling arm do not protrude laterally from the corresponding first side surface of the insulating body. Such a setting can effectively reduce the waste of space on the PCB board and improve the space utilization rate of the PCB board. Not only can the volume of the electronic device be reduced, but also the PCB board can have various designs to improve the performance of the electronic device.

[0005] The above-mentioned patent and traditional connectors need to weld the socket of the corresponding model on the PCB board surface, and then connect to the outside through the plug corresponding to the socket for debugging. This method requires welding the corresponding socket on each PCB board, which brings problems such as increased product cost and non-reusable socket materials. Summary of the Utility Model
