Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a pin-row high-current connector which is convenient for assembly and heat dissipation. Background Art

[0002] A type of connector originated from the military industry and is widely used in navigation, aerospace, electricity and other fields. The aviation plug is electrically connected after being plugged into the plug hole with wiring terminals on the aviation socket through a number of plug conductive pins. However, since the plug ends of most plugs and sockets are currently round or regular square, and there are many plug conductive pins, it takes too long to distinguish the correct direction of the socket and plug by human eyes before plugging them together. In addition, it is often necessary to use multiple connector components of the same appearance in a device, which makes it easy to plug in the wrong plug when plugging in, and the increased production cost is also high.

[0003] Connectors generally refer to electrical connectors, that is, devices that connect two active devices, transmit current or signals, and the male and female ends can transmit information or current after contact. Among them, connectors play the role of connection and conduction. Different manufacturers have different requirements for energy storage connectors. In general, they develop towards miniaturization and easy operation. Among connectors, elbow plug-in type is the representative, which can solve the problem of small space and easy operation.

[0004] Connectors are usually used as components for electrical connection or separation of transmission lines. They are mechatronics products. Simply put, they mainly play a bridging role. Connectors can be divided into plug-in connectors and threaded connectors according to the connection method. The male and female ends of current connectors are easily disconnected or loose when plugged in and out, which affects people's normal use of connectors. The connector connection has poor stability, poor heat dissipation, and inconvenient assembly.

[0005] In addition to meeting general performance requirements, electrical connectors must also have good contact, reliable operation, and easy maintenance. Whether they work reliably or not directly affects the normal operation of the circuit and involves the safety of the entire equipment. Existing signal pin header and high-current connectors for industrial equipment can basically meet daily use needs, but there are still some shortcomings that need to be improved. Most of the existing pin header and high-current connectors on the market that are easy to assemble and dissipate heat are connected to external connection lines through threads. However, during long-term use, once the connecting cable is accidentally touched by the outside world, it is very likely to cause the connection to loosen, resulting in poor contact of the equipment.

[0006] The existing connector connection methods mainly use bolts to lock the plug and socket or rely on a locking structure to lock the plug and socket after the plug and socket are plugged in. The bolt connection method can firmly and securely lock the plug and socket together after the bolts are locked, but the plug and socket are completely locked and cannot be rotated, and the bolts need to be unscrewed for disassembly and maintenance, which is very complicated to operate; the method of locking the plug and socket by relying on a locking structure after the plug and socket are plugged in is simpler in disassembly and assembly than the bolt connection, but it still requires laborious pressing of the locking structure to achieve the disassembly and assembly effect of the plug and socket, and the locking structure is complicated and costly to install during the production process, which is not conducive to improving production efficiency. Summary of the invention

[0007] The purpose of the present invention is to solve the above technical problems and provide a new type of pin-row high-current connector which is easy to assemble and dissipate heat.
