Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a rectangular connector for connecting to a PCB. Background Technology

[0002] In electronic devices, PCBs (Printed Circuit Boards) are essential basic components. Various electronic components need to be electrically connected to PCBs through connectors to achieve functions such as signal transmission and power supply. Rectangular connectors are widely used in PCB connection scenarios due to their advantages such as reliable connection and the ability to integrate a large number of contacts.

[0003] However, existing rectangular connectors used for PCB connections still have the following problems: First, the connection flexibility is poor, making it difficult to adapt to the complex spatial layout inside the equipment. When the equipment has a certain relative movement or the installation space is irregular, traditional rigid rectangular connectors are prone to connection interference, loosening, or even damage. Second, the stability after connection is insufficient. Under operating conditions such as vibration generated by the equipment, the connection between the connector and the PCB board is prone to loosening, affecting the reliability of the electrical connection, and thus leading to problems such as abnormal signal transmission and unstable power supply. Third, the heat dissipation performance needs to be improved. During operation, the connector generates heat due to the current passing through it. If the heat cannot be dissipated in time, long-term accumulation can easily affect the performance and service life of the connector and surrounding electronic components. Utility Model Content

When the equipment has relative movement or the installation space is irregular, it can effectively avoid connection interference, loosening, or even damage, greatly improving the flexibility of the connection.

[0018] 2. In this utility model, through the design of the connecting end assembly, the threaded female connector and the threaded male connector cooperate to achieve preliminary positioning. The combination of the connecting screw and the spring provides elastic pre-tightening force to offset the risk of loosening caused by vibration. At the same time, the slot and the corresponding snap-fit ​​structure of the PCB board cooperate to achieve physical limiting. This ensures the stability of the connection in many ways and effectively avoids problems such as loose connection and abnormal signal transmission caused by vibration.

[0019] 3. In this utility model, the auxiliary heat sink and the auxiliary heat dissipation guide hole are used together.

[0028] Please see Figures 1-4 In this embodiment of the present invention, a rectangular connector for connecting to a PCB includes a telescopic connection component 1 and a connection end component 2.

[0029] The telescopic connection assembly 1 includes an elastic spiral 11, a threaded connection female seat 12, and a threaded connection interface 13. The two ends of the elastic spiral 11 are connected to the threaded connection female seat 12, and the threaded connection female seat 12 is provided with the threaded connection interface 13. The elastic spiral 11 is made of TPU, an insulating material with elastic recovery capability, which can realize flexible extension and retraction of the connection length.

[0030] The connecting end assembly 2 includes a threaded connecting male seat 21, a threaded connecting contact head 22, a notch 23, a screw mounting hole 24, a connecting screw 25, a spring 26, an auxiliary heat sink 27, an auxiliary heat dissipation guide hole 28, an anti-slip rubber block 29, a rectangular connecting head 210, a slot 211, and a connector contact 212. The threaded connecting contact head 22 is located above the threaded connecting male seat 21 and is adapted to the threaded connecting interface 13. The notch 23 is opened at the four corners of the top of the threaded connecting male seat 21. The screw mounting hole 24 is opened on the inner bottom wall of the notch 23. The connecting screw 25 and the spring 26 are correspondingly arranged with the screw mounting hole 24. The spring 26 is fitted on the outside of the connecting screw 25. The connecting screw 25 passes through the corresponding screw mounting hole 24 to tighten the rectangular connecting head 210 after connection. The spring 26 can provide elastic preload to counteract vibration and other factors. To mitigate the risk of loosening, auxiliary heat sinks 27, made of copper, are fixedly connected to both ends of the threaded connector 21 in an array. Auxiliary heat dissipation guide holes 28 are arrayed between the upper and lower side walls of the threaded connector 21 for heat dissipation, working in conjunction with the auxiliary heat sinks 27 to accelerate heat dissipation. Anti-slip rubber blocks 29 are made of rubber and have anti-slip toothed grooves on the outside. They are fixedly connected to the front and rear ends of the threaded connector 21 by adhesive bonding, providing anti-slip properties and facilitating handheld or installation operations. A rectangular connector 210 is located at the center of the bottom end of the threaded connector 21.

Connector contacts 212 are arrayed inside the rectangular connector 210 and are made of a metal with excellent conductivity for electrical connection with the PCB board.

[0031] The working principle of this utility model is as follows: When connecting to the PCB board, the overall length of the connector is first adjusted by utilizing the elasticity of the elastic spiral 11 to fit the internal space of the equipment. The threaded contact head 22 on the threaded male connector 21 is then engaged with the threaded interface 13 of the threaded female connector 12 to achieve preliminary mechanical and electrical connection positioning. Next, the connecting screw 25 passes through the screw mounting hole 24, and with the elastic preload provided by the spring 26, the connection between the rectangular connector 210 and the PCB board is tightened. At the same time, the spring 26 can counteract the loosening caused by equipment vibration. To mitigate dynamic risks, the slot 211 on the rectangular connector 210 engages with the corresponding snap-fit ​​structure on the PCB board, further achieving physical limiting and ensuring connection stability. The connector contact 212 contacts the PCB board to achieve electrical connection for signal transmission or power supply. During connector operation, the auxiliary heat sink 27 and auxiliary heat dissipation guide hole 28 work together. The auxiliary heat sink 27 dissipates heat through the high thermal conductivity of copper, while the auxiliary heat dissipation guide hole 28 accelerates airflow and dissipates heat in a timely manner, ensuring the thermal stability of the connector. The anti-slip rubber block 29 facilitates hand operation by installers and improves assembly convenience.
