Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a pin header 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] A connector is generally considered to be a component attached to a cable or installed on an instrument. As a component for electrically connecting or separating a transmission line, it is a mechatronics product. Simply put, it mainly acts as a bridge. 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 is inconvenient to assemble. Summary of the invention

[0005] The purpose of the present invention is to solve the above technical problems and provide a new type of pin header connector which is easy to assemble and dissipate heat. The male end component is seamlessly butted and fastened to the female end component through a rotary locking assembly, so that the connection is more secure, and the conductive pins in the connector will not be pulled out when external force is applied, thereby improving the reliability of the connector; the rotary locking buckle is inserted into the locking cylindrical hole in the middle of the male end shell, and the rotary locking buckle can be rotated in the locking cylindrical hole, and a limiting groove is provided on the top of the rotary locking buckle, and the rotary limiting buckle is embedded in the limiting groove on the top of the rotary locking buckle, so that the male end component and the female end component are electrically connected, and the male end component and the female end component are prevented from being loose or loose when plugging and unplugging, thereby reducing stress concentration at the connection. This structure is more secure, more stable, easy to assemble, and has a good heat dissipation effect.
