[0001] The invention relates to the technical field of electronic components, and in particular discloses a dual-use, detachable connector structure for new energy vehicles. Background Art

[0002] With the rapid development of new energy vehicle technology, the electrical system in vehicles has become more and more complex. As important components of the electrical system, PCB boards (printed circuit boards) and electronic components usually assume control and drive functions. However, in actual applications, due to the influence of the external environment and the aging of components, the maintenance and replacement of PCB boards and electronic components has become a common demand.

[0003] Traditionally, PCBs and electronic components are connected by welding or fixed connections. Although these connection methods can provide stable electrical connections, they are inconvenient when repairs or component replacements are required. First, welding or fixed connections usually require professional tools for disassembly and assembly, resulting in long maintenance time and low efficiency. Second, since these connection methods are often not reusable, they are prone to damage to PCBs or electronic components during disassembly and assembly, increasing maintenance costs. Summary of the invention

[0004] In order to overcome the shortcomings and deficiencies in the prior art, an object of the present invention is to provide a connector structure that realizes easy assembly and disassembly connection between a PCB board and electronic components, thereby reducing the time for repairing and replacing components.

The present invention sets a second terminal and a first terminal, wherein the first terminal is electrically connected to the second terminal via its clamping portion, the first terminal is connected to an external PCB board, and the second terminal is connected to an external electronic component.

The external electronic components pass through the external PCB board through the clearance opening. This design allows the external electronic components or the PCB board to be disassembled separately, further improving the convenience of the connector. At the same time, the C-shaped structure enhances the stability of the connection, and also provides flexible disassembly options, which is conducive to the maintenance and replacement of electronic components.

[0007] Furthermore, the clamping portion includes an elastic arm, one end of the elastic arm is connected to the connecting portion, and the other end of the elastic arm is bent toward the second terminal to form a contact portion, and the contact portion is used to contact and conduct the second terminal. The elastic arm is provided with two groups, and the two groups of elastic arms are respectively arranged on the first plate portion and the second plate portion, and the two groups of elastic arms cooperate to clamp and contact the second terminal.

[0011] Furthermore, the support plates are provided in two groups, and the two groups of support plates are respectively located at two ends of the connection portion that are far away from each other.

This process uses larger components, such as DIP packaged integrated circuits, which need to be connected to the circuit board through sockets.

[0013] Furthermore, the connecting portion is provided with a support arm bent outward from the connecting portion, and two groups of support arms are provided, and the two groups of support arms are respectively arranged at the free ends of the first plate portion and the second plate portion.

At the same time, the C-shaped structure enhances the stability of the connection and provides flexible disassembly options, which is conducive to the maintenance and replacement of electronic components.

[0017] Selecting the elastic arm with appropriate thickness can provide the best elasticity and strength, ensuring that it can maintain its elasticity and durability after long-term use, while ensuring a certain sense of insertion;

[0018] After the connecting part is set into a C-shaped structure, one side of the opening lacks support and has low stability. The two support arms extend to both sides respectively, and the connecting part forms a tripod structure, which increases the overall rigidity of the connector and further prevents the connector from deforming during use, so that the connector can still maintain its shape and function under harsh conditions.
