Description
Technical Field
[0001] This utility model relates to the field of main circuit connector technology, specifically a novel main circuit connector. Background Technology
[0002] Main circuit connectors are a technology used for connecting and plugging main circuits. They can be used in various electronic devices, circuit boards, and systems for connecting power supplies, signal transmissions, and other functions. Main circuit connectors typically consist of a socket and a plug. The socket is usually soldered onto the circuit board, while the plug connects to the electronic device or component. Connecting the circuit by inserting the plug into the socket facilitates debugging, maintenance, and replacement. Main circuit connectors play a crucial role in the design and manufacture of electronic devices. However, in existing technologies, high-current connectors present a trade-off between insertion / removal force and conductivity during device use. Excessive pressure leads to difficulty in insertion and removal, and traditional solutions that increase conductive points raise costs and insertion / removal resistance. Therefore, improvements are needed. Utility Model Content
[0003] The purpose of this utility model is to provide a new type of main circuit connector, which solves the problem that when the device is in use, there is a contradiction between the insertion and extraction force and the conductivity of the high current connector. Excessive pressure will lead to difficulty in insertion and extraction, and the traditional solution will increase the cost and insertion and extraction resistance by adding conductive points.

[0010] The beneficial effects of this utility model are as follows:
[0011] 1. This utility model designs components such as clamping blocks, connecting sleeves, spring steel sheets, connecting plates, connecting parts, and fixing plates. It uses spring steel sheets with different coefficients of thermal expansion. At room temperature, the pressure is moderate, making insertion and removal easy. After being energized and heated, the contact pressure automatically increases due to the difference in material expansion, thereby reducing the temperature rise. The key is to achieve low-cost and highly reliable adaptive adjustment by customizing differentiated spring steel sheet materials and optimizing the bonding process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-4 A novel main circuit connector includes a housing 1, a clamping block 2 inside the housing 1, a connecting sleeve 3 outside the clamping block 2, a spring steel sheet 4 outside the clamping block 2, a spring steel sheet 4 inside the connecting sleeve 3, a connecting plate 5 in contact with the clamping block 2, the connecting plate 5 in contact with the housing 1, a connecting piece 6 outside the connecting plate 5, a fixing plate 7 fixedly connected to the upper end of the housing 1, two screws 8 inside the fixing plate 7, the two screws 8 being symmetrically distributed inside the fixing plate 7, the screws 8 being designed to connect to the fixing plate 7, a rotating block 9 fixedly connected to the screw 8, the rotating block 9 in contact with the fixing plate 7, and a limit mechanism 10 on the fixing plate 7.
[0020] Please see Figure 4 The limiting mechanism 10 includes an annular groove 101. The rotating block 9 has an annular groove 101 inside. A slider 102 is slidably connected inside the annular groove 101. A connecting seat 103 is fixedly connected to the outside of the fixed plate 7. A sliding plate 104 is slidably connected inside the connecting seat 103. A moving plate 105 is fixedly connected to the sliding plate 104. The moving plate 105 contacts the connecting seat 103. By designing the moving plate 105, the sliding plate 104 can be moved. A spring 106 is provided inside the connecting seat 103. One end of the spring 106 is fixedly connected to the sliding plate 104, and the other end of the spring 106 is fixedly connected to the connecting seat 103. By designing the spring 106, the sliding plate 104 has an elastic force.
[0021] Please see Figure 4 The connecting seat 103 has a sliding groove 107 inside, and a guide block 108 is slidably connected inside the sliding groove 107. An elastic block 109 is engaged inside the guide block 108. The elastic block 109 is fixedly connected to the connecting seat 103. By designing the elastic block 109, the guide block 108 can be limited. The guide block 108 is fixedly connected to the slider 102. The rotating block 9 is in contact with the connecting seat 103. The connecting seat 103 is slidably connected to the slider 102. A sliding plate 104 is fixedly connected to the outside of the slider 102. By pulling the slider 102 to a designated position, the rotating block 9, the screw 8 and the annular groove 101 are installed on the fixed plate 7 at the designated position. Then the slider 102 is moved into the annular groove 101, thereby limiting the screw 8 and other components and preventing the screw 8 on the device from loosening after long-term use.
[0022] The specific implementation process of this utility model is as follows: Before using the device, pull the movable plate 105 to move it away from the slider 102. The movement of the movable plate 105 drives the sliding plate 104 to move, and the movement of the sliding plate 104 drives the slider 102 to move. At the same time as the sliding plate 104 moves, the spring 106 is compressed. The movement of the slider 102 drives the guide block 108 to move. The guide block 108 moves and separates from the elastic locking block 109. After the slider 102 and other components move to the designated position, the rotating block 9 moves towards the fixed plate 7. The rotating block 9 moves... The moving plate 105 moves the annular groove 101 and the screw 8. The screw 8 and other components move and are installed in the designated position in the fixed plate 7. Then the moving plate 105 is released, and the elastic force of the spring 106 pushes the sliding plate 104 to move. The movement of the sliding plate 104 drives the slider 102 and other components to move. The movement of the slider 102 drives the guide block 108 to move. After the slider 102 moves into the annular groove 101, the guide block 108 and the elastic locking block 109 form a locking, thereby limiting the screw 8 and other components and preventing the screw 8 on the device from loosening after long-term use.
[0023] When the device is in use, spring steel sheets 4 with different coefficients of thermal expansion are used. At room temperature, the pressure is moderate and easy to insert and remove. After being powered on and heated, the contact pressure automatically increases due to the difference in material expansion, thereby reducing the temperature rise. The key is to achieve low-cost and highly reliable adaptive adjustment by customizing differentiated spring steel sheet 4 materials and optimizing the bonding process.
