Description

Technical Field

[0001] The utility model relates to the technology of connector field, in particular to a miniature waterproof magnetic board-end connector. Background Art

[0002] Connectors are also called connectors. In China, they are also called joints and sockets, and generally refer to electrical connectors. That is, a device that connects two active devices to transmit current or signals. The male end and the female end can transmit information or current after contact, and are also called connectors; the basic performance of connectors can be divided into three categories: mechanical performance, electrical performance, and environmental performance. Another important mechanical performance is the mechanical life of the connector. It is based on one insertion and one removal as a cycle, and whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and removal cycle is used as the basis for judgment. Among them, the board-end connector is also a type of connector.

[0003] When assembling existing board-side connectors, in order to meet the waterproof performance requirements, a sealing gasket structure is generally added, which makes the overall structure of the board-side connector more complicated and the assembly process more troublesome. In addition, the sealing gasket is easily damaged after long-term use, thereby affecting its waterproof performance and further affecting the overall service life of the connector. Therefore, it is necessary to make further improvements to the existing board-side connector structure. Utility Model Content
