Description

Technical Field

[0001] The utility model belongs to the field of board-to-board connectors, and in particular relates to a board-to-board connector. Background Art

[0002] Board-to-board connectors have the strongest transmission capabilities among all current connector product types and are mainly used in power systems, communication networks, financial manufacturing, elevators, industrial automation, medical equipment, office equipment, home appliances, military manufacturing and other industries.

[0003] The prior art has specially developed some board-to-board connectors. For example, the Chinese patent with the announcement number "CN220895889U" discloses "a board-to-board connector". Through the setting of a fixing component, during the connection process between the connector socket and the connector plug, the elastic action of the limit spring makes the card block close to the inside of the card slot, thereby fixing the connector plug inside the connector socket. The structure is simple, the installation is quick and convenient, and its installation efficiency is improved.

[0004] Although the fixing component is set, during the connection process between the connector socket and the connector plug, the limit spring makes the card block close to the inside of the card slot, fixing the connector plug inside the connector socket, which has a simple structure, quick and convenient installation, and improves its installation efficiency, but in actual use, the connector plug will be scratched and fallen off if the staff is not careful, and the connector plug cannot be effectively fixed. It can only achieve the effect of clamping the connector plug, but cannot effectively fix the connector plug. When the connector plug is connected to the connector socket, there is no effective guiding structure. When the staff connects the connector plug to the connector socket, it may get stuck, resulting in the sleeve rod being unable to effectively connect with the plug pin. At this time, the plug pin will be deformed. When the plug pin is connected to the sleeve rod, there is no protection and sealing structure at the connection port. After long-term removal and insertion, a large amount of dust will accumulate inside the sleeve rod. In this way, when the plug pin is slidably connected inside the sleeve rod, an unstable connection will occur. Utility Model Content
