Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a high-current connector. Background Technology

[0002] Electrical connectors, as key components in electrical and electronic systems, are responsible for establishing temporary or permanent connections between different circuit boards, cables, devices, or systems, ensuring reliable transmission of current or signals. Connectors are widely used in electronic and electrical equipment. With the rapid development and continuous optimization of my country's industry, the requirements for the stability and reliability of high-current transmission in automotive equipment are increasing. Especially for automotive and heavy-duty vehicles, their power supply equipment must not only meet the basic requirements of high-current transmission but also ensure the stability and high efficiency of power supply.

[0003] However, during high-current transmission, electrical connectors often face the challenge of rapidly increasing temperatures. This not only leads to a decline in electrical performance but can also cause uneven material expansion, poor thermal conductivity, and soldering problems, thereby affecting the stability and safety of the equipment. More seriously, high temperatures can accelerate the deterioration of connector performance and even cause catastrophic accidents such as ablation and melting.

[0004] Against this backdrop, the applicant, through in-depth research and practice, has successfully found an effective method to solve these problems. The technical solution described below was developed in response to this urgent need, aiming to overcome the shortcomings of existing technologies and provide a more reliable and efficient solution.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In this embodiment of the utility model, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0025] Reference example Figures 1 to 5 A high-current connector includes a socket 1 and a plug 2. The plug 2 is provided with a conductive terminal head 3. The socket 1 is provided with a conductive post 4 that accommodates the conductive terminal head 3 and abuts against it. The outer wall of the socket 1 and the plug 2 is provided with a heat-conducting plate 5. The outer wall of the heat-conducting plate 5 is provided with a plurality of equally spaced heat dissipation fins 51 evenly distributed along the circumferential direction. The inner wall of the heat-conducting plate 5 is provided with a plurality of raised heat-conducting parts 52. The conductive post 4 and the conductive terminal head 3 are connected to a terminal block 6. The terminal block 6 is provided with an extension 61. The two sides of the extension 61 are provided with a plurality of equally spaced heat-conducting grooves 62. The socket 1 and the plug 2 are filled with thermal grease and are tightly fitted with the extension 61 and the heat-conducting plate 5.

[0026] During current transmission, the heat generated by the connection between the conductive terminal 3 and the conductive post 4 is rapidly and efficiently conducted to the heat-conducting plate 5 through the thermal grease. The heat dissipation fins 51 on the heat-conducting plate 5 exchange heat effectively with the outside cold air, thereby controlling the operating temperature of the conductive terminal 3 and the conductive post 4. In addition, the design of the heat dissipation part and the heat-conducting groove 62 further increases the contact area with the thermal grease, significantly improving the heat conduction efficiency. Even in a sealed state, the above heat dissipation structure can ensure that the temperature rise of the conductive terminal 3 and the conductive post 4 is always maintained within the safe threshold. This heat dissipation structure effectively prevents the adverse effects of high temperature on the stability and safety of the equipment, slows down the deterioration process of the connector performance, and avoids serious accidents such as ablation and melting. Therefore, this technical solution significantly improves the stability and reliability of the product and ensures the safe operation of the equipment.

[0027] It is worth mentioning that the terminal block 6 is provided with a terminal block 63, the terminal block 63 is provided with a groove 64 that conforms to the surface of the cable, the groove 64 is provided with a number of anti-slip grooves 65, and at least one guide groove 66 is provided on both sides of the terminal block 63. The guide groove 66 is provided with a liftable pressure plate 7, and the other end of the pressure plate 7 is provided with a fastening screw 71, which abuts against the back of the terminal block 63. The anti-slip grooves 65 increase the friction between the groove 64 and the exposed part of the cable, thereby increasing the stability of the electrical connection. As the fastening screw 71 is gradually tightened, the pressure plate 7 and the groove 64 gradually approach each other, thereby pressing the exposed part of the cable into the groove 64.

[0028] It is worth mentioning that the extension 61 is provided at one end of the terminal 63. The extension 61 is located below the groove 64. The design structure of the extension 61 being lower than the groove 64 is to avoid interfering with the electrical connection between the exposed part of the cable and the groove 64.

[0029] It is worth mentioning that the back of the heat-conducting plate 5 is provided with a flange 53, which fits tightly against the inner wall of the socket 1 and the plug 2. The flange 53 is used to install and fix the heat-conducting plate 5 to the inner wall of the socket 1 and the plug 2 with screws. The heat-conducting part 52 is provided in the flange 53.

[0030] It is worth mentioning that the plug 2 has a raised part 21 that protrudes and covers the conductive terminal head 3. Since the high current is usually between 630A and 800A, the raised part 21 increases the creepage distance between adjacent conductive terminal heads 3, thereby increasing the electrical performance of the product.

[0031] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
