[0041] The application will be further described in detail below with the aid of the drawings and examples.

[0042] Referring toFigures 1 to 5 The embodiment of the present application provides a high-conductivity contact sheet structure for an electric connector, which comprises an electric connector body 1, a connecting barrel 101 and a connecting head 102. The connecting barrel 101 is arranged on the surface of the electric connector body 1, and the connecting head 102 is matched with the connecting barrel 101. The connecting barrel 101 is internally provided with a spring assembly 8. The spring assembly 8 comprises a mounting groove 801 arranged on the inner wall of the connecting barrel 101. A damping spring 802 is fixedly arranged in the mounting groove 801. One end of the damping spring 802 is fixedly connected with a contact sheet assembly 7. When the connecting head 102 is inserted into the connecting barrel 101, the contact sheet assembly 7 first contacts the connecting head 102. With further insertion of the connecting head 102, the contact sheet assembly 7 is extruded, and the damping spring 802 is compressed. The damping spring 802 utilizes the elastic property thereof to generate a reverse force, tightly presses the contact sheet assembly 7 on the connecting head 102, and ensures good contact. When the equipment is subjected to vibration or impact, the damping spring 802 can absorb part of the energy, compensates for the possible displacement between the contact sheet assembly 7 and the connecting head 102 through the expansion and contraction of the damping spring 802, thereby keeping the relative stability of the contact force, preventing the increase of the contact resistance or the disconnection, greatly improving the reliability of the electric connector in the vibration and impact environment, and reducing the risk of circuit failure caused by poor contact.

[0043] With reference to Figure 2 In one aspect of the embodiment, the contact sheet assembly 7 comprises an insulating arc-shaped plate 701 fixedly connected to the surface of the connecting plate 803. The inner wall of the insulating arc-shaped plate 701 is fixedly arranged with a high-conductivity contact sheet 702. The insulating arc-shaped plate 701 plays a role of insulation and support, ensures the electrical isolation between the high-conductivity contact sheet 702 and other components, and tightly adheres to the contact surface of the connecting head 102 under the action of the spring assembly 8, thereby forming a low-resistance conductive path. When the electric current passes through, the high-conductivity contact sheet 702 can effectively transmit the electric current. The good conductivity of the high-conductivity contact sheet 702 reduces the energy loss and heating phenomenon in the process of electric current transmission. The excellent conductivity of the high-conductivity contact sheet 702 improves the transmission efficiency of the electric connector, reduces the contact resistance, and reduces the heating and energy loss. The design of the insulating arc-shaped plate 701 ensures the electrical safety and prevents the occurrence of faults such as short circuit. Meanwhile, the cooperation of the contact sheet assembly 7 and the spring assembly 8 enables the contact sheet assembly 7 to maintain stable contact performance under different working conditions, and further improves the reliability and stability of the electric connector.

[0044] With reference to Figure 4In one aspect of the embodiment, the side surface of the connecting cylinder 101 is provided with a positioning assembly 5, which comprises a positioning frame 501 fixedly connected to the side surface of the connecting cylinder 101, and a working block 502 fixedly connected to the side surface of the connecting head 102, and a positioning column 503 fixedly connected to the surface of the working block 502 and matched with the positioning frame 501.

[0045] One side of the positioning assembly 5 is provided with a connecting assembly 3, which comprises a connecting frame 301 fixedly connected to the side surface of the connecting cylinder 101, and a connecting block 302 fixedly connected to the side surface of the connecting head 102 and matched with the connecting frame 301.

[0046] The surface of the connecting cylinder 101 is provided with a sealing assembly 4, which comprises a sealing gasket 401 adhesively connected to one end of the connecting cylinder 101, and a sealing ring 402 adhesively connected to the surface of the connecting cylinder 101 and located at the connecting position of the electric connector body 1 and the connecting cylinder 101. In the process of inserting the connecting head 102 into the connecting cylinder 101, the positioning column 503 moves with the working block 502, and when the connecting head 102 is fully inserted, the positioning column 503 is accurately inserted into the corresponding position of the positioning frame 501. The cooperation between the positioning frame 501 and the positioning column 503 not only ensures the correct alignment of the connecting head 102 and the connecting cylinder 101, but also prevents the displacement of the connecting head 102 in the vertical direction to a certain extent, thereby ensuring the accuracy and stability of the connection. When the connecting head 102 is inserted into the connecting cylinder 101, the connecting block 302 enters the corresponding position of the connecting frame 301, and the connecting frame 301 and the connecting block 302 are matched in shape and size to form a tight mechanical connection, thereby restraining and fixing the position of the connecting head 102 in the connecting cylinder 101 and preventing the displacement of the connecting head 102 in the horizontal direction, thus ensuring the stability and accuracy of the connection. The sealing gasket 401 is adhesively connected to one end of the connecting cylinder 101, and when the connecting head 102 is inserted into the connecting cylinder 101, the sealing gasket 401 is pressed between the connecting head 102 and the connecting cylinder 101 to form the first sealing line, thereby preventing impurities such as dust and moisture from entering the electric connector from the connecting position. At the same time, the sealing ring 402 is adhesively connected to the connecting position of the connecting cylinder 101 and the electric connector body 1, which further prevents external impurities from entering from the gap, thereby providing comprehensive sealing protection for the electric connector.

[0047] Referring to Figure 5 In one aspect of the embodiment, the surface of the electric connector body 1 is provided with a heat conduction assembly 2, which comprises a heat conduction groove 201 formed in the surface of the electric connector body 1, and a plurality of heat dissipation fins 202 arranged in the heat conduction groove 201, one end of each heat dissipation fin 202 extending into the electric connector body 1.

[0048] The surface of the electric connector body 1 is provided with a heat dissipation assembly 6, which comprises a heat dissipation groove 601 opened on the surface of the electric connector body 1, and a dustproof screen 602 arranged in the heat dissipation groove 601. The heat dissipation groove 601 provides a channel for heat dissipation inside the electric connector body 1, and the heat can be dissipated to the surrounding environment by natural convection. The dustproof screen 602 is installed in the heat dissipation groove 601, which can prevent dust and other impurities from entering the electric connector body 1 through the heat dissipation groove 601, and will not significantly hinder the heat dissipation. The heat dissipation channel is unobstructed, and the heat generated by the electric connector body 1 during operation will be transferred to the heat dissipation fins 202 in the heat conduction groove 201. The heat dissipation fins 202 have a large surface area and can quickly dissipate heat to the surrounding environment. Since one end of the heat dissipation fins 202 extends into the electric connector body 1, it can more efficiently conduct heat from the inside and speed up the heat dissipation, thereby reducing the temperature of the electric connector body 1.

[0049] Working principle: In use, the connecting head 102 is inserted into the connecting barrel 101, the contact sheet assembly 7 first contacts the connecting head 102 and is pressed, causing the shock-absorbing damping spring 802 in the spring assembly 8 to compress, thereby tightly pressing the contact sheet assembly 7 on the connecting head 102, ensuring good electrical contact, and the spring can stabilize the contact force under vibration and impact. Then, during the insertion of the connecting head 102, the positioning column 503 of the positioning assembly 5 moves with the working block 502, and finally accurately inserts into the positioning frame 501, ensuring the vertical alignment and stability of the connecting head 102 and the connecting barrel 101. The connecting block 302 of the connecting assembly 3 enters the connecting frame 301, ensuring the horizontal connection stability, and then the sealing gasket 401 and the sealing ring 402 of the sealing assembly 4 form a sealing line at the connecting part and the connection part with the electric connector body 1 respectively, preventing dust and moisture from entering. After the electric connector body 1 generates heat during operation, the heat dissipation fins 202 of the heat conduction assembly 2 conduct and dissipate heat, the heat dissipation groove 601 of the heat dissipation assembly 6 provides a channel for heat dissipation, and the dustproof screen 602 prevents dust from entering, thereby ensuring the stable and efficient operation of the electric connector.
