Technical Field

[0001] The utility model relates to the technical field of connector connection, in particular to an aircraft buckle with waterproof function. Background Art

[0002] Connectors, also known as connectors, plugs and sockets, generally refer to electrical connectors. That is, devices that connect two active devices to transmit current or signals. They are widely used in military systems such as aviation, aerospace, and national defense.

[0003] The JST connector is a common electronic connector used to connect electronic devices and circuit boards. It has the characteristics of miniaturization, high reliability, and easy operation. The JST connector is widely used in computers, consumer electronics, automobiles, industrial equipment and other fields. It can be used to connect various devices such as LCD screens, batteries, cameras, sensors, etc. The JST connector is generally composed of a plastic shell and a connecting piece. When connected, it is directly plugged in. The connection structure is not stable enough and is easy to fall off or have poor contact. At present, most JST connectors are connected and fixed to sheet metal parts by cable ties. The connector is tied and fixed to the sheet metal part, but the cable tie fixing method makes it difficult to accurately locate the connector installation position, and the connector installation firmness is poor.

[0004] The Chinese utility model patent with the patent number of 202021977657.0 discloses an aircraft buckle for fixing the JAE connector, including an elastic plug, a baffle and a connector. The elastic plug is a plug rod with the bottom end connected to the middle of the V-shaped plug buckle. The cavity between the inner wall of the plug buckle and the plug rod constitutes an extrusion deformation cavity. The top of the plug rod is connected to the baffle. The connector is located on the other side of the baffle. The connector is provided with a slot for connecting with the JAE connector. It is only necessary to open a round hole on the fixed plate, and the elastic plug connector is pressed into it, and the JAE connector is connected to the connector. In assembling lithium-ion batteries, it is only necessary to open a round hole on the fixed plate. The operation is convenient and quick, and the JAE connector can also be disassembled. However, the aircraft buckle of the above structure cannot achieve effective closure of the sheet metal hole, does not have a waterproof function, and the connection firmness and vibration buffering function between the aircraft buckle and the sheet metal part still need to be further improved.
