Description

Technical Field

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

[0002] A connector is an electronic component used for the transmission and exchange of current or signals between devices in an electronic system. As a node, it transmits current or signals between electronic products, components, devices, and subsystems, either independently or in conjunction with cables, while maintaining signal distortion and energy loss between systems. It is a fundamental component essential for the electrical connections of the entire circuit system. High-current connectors are used in applications such as power tools and electric vehicle charging interfaces, where connectors require advantages such as fast connection, high reliability, and adaptability to complex environments. In the power control equipment industry, terminals are accessories mounted on PCBs in control cabinets to achieve electrical connections. Terminals are used to facilitate wire connections; they are metal pieces encased in insulating plastic with holes at both ends for wire insertion and screws for tightening or loosening. They can be used to connect wires and can be disconnected at any time.

[0003] A search revealed a high-voltage, high-current connector disclosed in Chinese patent publication number CN106654727A.

[0004] However, the aforementioned patented devices have shortcomings in use: traditional high-current connectors have simple structures and functions, and the devices have dedicated terminals inside, which can cause assembly orientation problems during assembly. The terminals are inconvenient to use, reducing the work efficiency of operators and providing insufficient protection against electric shock for users.

[0005] To address these issues, we have introduced a safe and convenient high-current connector structure. Utility Model Content

[0006] The purpose of this utility model is to provide a vital sign detection device with emergency rescue function, so as to solve the problems mentioned in the background art, such as the simple structure and function of traditional high current connectors, the existence of special terminals inside the device, the assembly direction problem during assembly, the inconvenience of using the terminals, the reduction of the work efficiency of operators, and the insufficient protection against electric shock for users.

[0007] To address the aforementioned problems, this utility model provides a high-current connector structure.

[0008] The objective of this utility model can be achieved through the following technical solution: A high-current connector includes a terminal body shell, a terminal cover plate, a long conductive plate, a short conductive plate, a wire clamping frame, a wire clamping block, a wire clamping screw, and two sets of screws. The long or short conductive plate, together with the wire clamping frame, the wire clamping block, the wire clamping screw, and the two sets of screws, can form a metal assembly. The wire clamping frame has a wire frame groove structure for placing the clamping block boss structure, and the wire clamping frame also has a threaded hole structure for assembling the wire clamping screw. This assembled metal assembly controls the wire clamping block in the wire clamping frame by tightening and loosening the wire clamping screw. The size of the wiring hole structure formed by the long or short conductive plate determines whether the wire is tightened or loosened. The long and short conductive plates each have their own screw holes, which can be engaged with two sets of screws. By locking or releasing the two sets of screws onto the long or short conductive plate, the screw pad structure can tighten or loosen the wire. The terminal body housing has a wiring cavity structure that can hold the long or short conductive plate, the wire clamping block, the wire clamping frame, the wire clamping screw, and the metal assembly composed of the two sets of screws. The terminal cover can be accessed through the terminal... The main body shell's boss structure and the terminal cover plate's groove structure engage tightly with the terminal main body shell. The terminal cover plate has screw operating holes, with the wire clamping screws positioned below the surface of these holes to effectively prevent electric shock during use. The terminal main body shell has two sets of screw slots. When the metal component is inserted into the wiring cavity on the terminal main body shell, either the long or short guide plate screw hole structure will engage with one of the two sets of screw slots. Users can directly use the two sets of screws to lock into place. The product features a foolproof design. The terminal body housing has a structure with wing A and wing B, while the terminal cover has a structure with wing slot A and wing slot B. During product assembly, wing A can only be engaged with wing slot A, and wing B can only be engaged with wing slot B. This ensures the correct orientation when the terminal cover and terminal body housing are mated. Furthermore, the terminal cover has a boss structure, allowing customers to use a fixture to secure the product through this boss structure for easier operation. These features make using this high-current connector safer and more convenient than with ordinary products.

[0009] Furthermore, the long or short conductive plate, together with the wire clamping frame, wire clamping block, wire clamping screw, and two sets of screws, can form a metal assembly. The wire clamping frame has a wire frame groove structure for placing the clamping block boss structure, and the wire clamping frame also has a threaded hole structure for assembling the wire clamping screw. This assembled metal assembly controls the size of the wiring hole structure formed by the wire clamping block and the long or short conductive plate in the wire clamping frame by tightening and loosening the wire clamping screw, thereby achieving the purpose of locking or loosening the wire. The long and short conductive plates respectively have long guide plate screw hole structures and short guide plate screw hole structures, which can be locked with the two sets of screws. By locking and unlocking the two sets of screws with the long or short conductive plates, the two sets of screw pad structures can press or loosen the wire.

[0010] Furthermore, the terminal body shell has a wiring cavity structure that can accommodate a long or short conductive plate, a wire pressing block, a wire pressing frame, a wire pressing screw, and a metal assembly consisting of two sets of screws. The terminal cover can be tightly fitted to the terminal body shell through the engagement of the boss structure and the groove structure of the terminal cover. The terminal cover has a screw operating hole structure, with the wire pressing screw lower than the surface of the wire pressing screw hole structure, which can effectively prevent the risk of electric shock to the user during use. The terminal body shell has two sets of screw slot structures. When the metal assembly is placed into the wiring cavity structure on the terminal body shell, the long or short conductive plate screw hole structure will be in the two sets of screw slot structures, and people can directly use the two sets of screws to lock the long or short conductive plate screw holes.

[0011] Furthermore, to ensure the product has a foolproof design, the terminal body housing has a wing a and a wing b structure, while the terminal cover has a wing groove a and a wing groove b structure. During product assembly, wing a can only be engaged with wing groove a, and wing b can only be engaged with wing groove b. This ensures the orientation of the terminal cover and the terminal body housing during mating. The terminal cover also has a boss structure, allowing customers to use a fixture to secure the product via this boss structure for easier operation. These structural features make using this high-current connector safer and more convenient than with typical products.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model discloses a high-current connector. The device has dedicated terminals inside. The terminal cover can be tightly fitted to the terminal body shell through a boss structure and a groove structure. The terminal cover also has screw holes with the wire clamping screws recessed below the surface of the screw holes, effectively preventing the risk of electric shock during use. Furthermore, the boss structure on the terminal cover allows customers to use a fixture to secure the product, facilitating operation. These features make using this high-current connector safer and more convenient than with conventional products, and the fixture-assisted securing mechanism improves the device's efficiency.
