Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and particularly to a quick plug - and - unplug high - current connector applied to 600A. Background Art

[0002] One type of connector originated from the military industry and is widely used in fields such as navigation, aerospace, and electric power. The aviation plug is electrically connected after being inserted into the insertion holes with wiring terminals on the aviation socket through several plug conductive pins. However, since most of the insertion ends of current plugs and sockets are circular or regular square, and there are many plug conductive pins, it takes too long to insert after first distinguishing the correct directions of the socket and the plug by the human eye. In addition, in a device, it is often the case that multiple connector components with the same appearance need to be used. Then, it is easy to insert the plug wrongly when plugging, and the increased production cost is also relatively high.

[0003] A connector generally refers to an electrical connector, that is, a device connecting two active devices, transmitting current or signals. The male end and the female end can transmit information or current after contact, and it is also called a connector. Among them, the connector plays the role of connection and conduction. Different manufacturers have different requirements for energy - storage connectors, and generally tend to develop towards miniaturization and convenient operation. The elbow plug - in type is representative among connectors, which can solve the problems of small space and convenient operation.

[0004] A connector is usually used as an element for electrical connection or separation of transmission lines. It belongs to mechatronic products. Simply speaking, it mainly plays a bridging role. Connectors can be divided into plug - and - unplug connectors and threaded connectors according to the connection method. At present, the male end and the female end of the connector are prone to disconnection or looseness when being plugged and unplugged, and are also prone to relaxation, thus affecting the normal use of the connector by people. The stability performance of the connector connection is poor, the heat dissipation effect is poor, and the assembly is not convenient.

[0005] In addition to meeting general performance requirements, a particularly important requirement for an electrical connector is that it must have good contact, reliable operation, and convenient maintenance. Whether its operation is reliable directly affects the normal operation of the circuit and involves the safety of the entire device. The existing signal pin high - current connectors for industrial equipment can basically meet the daily use requirements, but there are still some deficiencies that need to be improved. Most of the existing pin high - current connectors that are convenient for assembly and heat dissipation on the market are connected to the external connection line through threads. However, during long - term use, once the connected cable is accidentally touched by the outside, it is very likely to cause loosening at the connection, resulting in poor contact of the device.

[0006] The connection methods of existing connectors mainly rely on bolt tightening of the plug and socket or the plug and socket are inserted into each other and then locked by a locking structure. In the case of bolt connection, after the bolts are tightened, the plug and socket can be firmly locked together. However, the plug and socket are completely locked and cannot be rotated, and disassembly, installation, and maintenance all require unscrewing the bolts, making the operation very complex. In the method of inserting the plug and socket into each other and then relying on the locking structure to lock the plug and socket, it is more convenient for disassembly and installation compared to bolt connection. However, it still requires pressing the lock with effort to achieve the disassembly and installation effect of the plug and socket. Moreover, the lock-type structure is relatively complicated to install and costly during the production process, which is not conducive to improving production efficiency.

[0007] Existing plug-and-play connectors generally achieve fixed plugging through the friction force between the plug and the socket. When unplugging, hold the plug and pull it out forcefully. After long-term use of this type of connector, the friction force between the plug and the socket will gradually decrease, resulting in poor connection stability, easy occurrence of open circuit, and it is laborious to plug and unplug, and the terminals are easily damaged. To improve the plugging stability of the plug-and-play connector, currently, an elastic snap structure is provided on the side walls of the plug and socket of the plug-and-play connector. When the plug and the socket are plugged, the elastic snap structures on the side walls of the plug and the socket are automatically snap-connected, improving the connection stability between the plug and the socket. However, before unplugging the plug of this type of connector, it is necessary to first release the snap connection of the elastic snap structures on the side walls of the plug and the socket, and then the plug can be pulled outwards, which is not convenient to use and time-consuming.

[0008] Chinese patent CN116581604A discloses a quick plug-in connector, including a socket and a plug, wherein the plug is provided with a plug-in hole, and the plug-in head on the socket can be plugged into the plug-in hole of the plug, and also includes a lock and a lock handle, wherein a lock slideway cross-connected with the plug-in hole is provided on the side wall of the plug, and the lock can be slidably inserted into the lock slideway, and one end of the lock can slide into the plug-in hole and prevent the plug-in head in the plug-in hole from sliding toward the opening direction of the plug-in hole, and a lock handle slideway is also provided on the side wall of the plug, and the lock handle slideway is connected with the lock slideway, and a lock handle can be slidably inserted in the lock handle slideway for a set distance, one end of the lock handle is fixedly connected to the lock, and the other end of the lock handle extends outward from the side wall of the plug, and a reset elastic structure is also provided in the lock slideway or the lock handle slideway, and the reset elastic structure The structure provides an elastic holding force to the lock buckle or the lock buckle handle so that the lock buckle has a tendency to slide toward the plug-in hole. The present invention provides a lock buckle slideway cross-connected with the plug-in hole on the side wall of the plug, and a lock buckle handle slideway connected with the lock buckle slideway is provided on the side wall of the plug. When unplugging the plug, the lock buckle handle in the lock buckle handle slideway can be pressed by fingers to drive the lock buckle to slide in the lock buckle slideway to unlock the plug and the socket. This structure unlocks the plug and the socket while holding the plug, and then the plug can be directly unplugged out, thereby realizing rapid unplugging of the plug from the socket and avoiding the step-by-step unlocking and unplugging of the plug, which can be completed in one action. When the plug is inserted into the socket, the lock buckle will automatically buckle and lock with the plug without additional operation. The present invention has a simple structure and is easy to operate. It can realize rapid plugging and separation of the plug and the socket, and is easy and quick to operate.
