[0020] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not limiting of the scope of protection of this utility model.
[0021] Please see Figure 1-4This utility model provides a technical solution: a metal terminal for fixing wires in a transformer, comprising a terminal body 1, which serves to conduct electricity; a connecting post 2 is fixedly installed at the bottom of the terminal body 1, which is used to install corresponding components; a cavity is opened inside the connecting post 2; a fixing rod 3 is installed at the front end of one side of the connecting post 2, which is used to press rollers 4; pressure rollers 4 are fixedly installed at the top and bottom of the rear surface of the fixing rod 3, which can press the wires; a movable groove 5 is opened at the middle of the front surface of the connecting post 2, which facilitates the lateral movement of pins 8; limit grooves 6 are opened at the top and bottom of the movable groove 5, which are used to engage with pins 8; a connecting groove 7 is opened at the middle of the front surface of the fixing rod 3, which facilitates the vertical movement of pins 8; two pins 8 are installed at the middle of the connecting groove 7, which serve to engage and limit.
[0022] Furthermore, the front surface of the terminal body 1 is provided with a mounting groove 9, which is an integral design with the terminal body 1. The mounting groove 9 facilitates the installation of the terminal body 1.
[0023] Furthermore, a through groove 10 is provided at the bottom of the connecting post 2. The through groove 10 and the connecting post 2 are integrated into one piece. The through groove 10 facilitates the entry of wires into the interior of the connecting post 2.
[0024] Furthermore, a rubber ring 11 is fitted on the outer surface of the pressure roller 4, wherein the rubber ring 11 can increase the friction between the pressure roller 4 and the wire.
[0025] Furthermore, the number of limiting grooves 6 is several, and each pair of limiting grooves 6 is designed to be equidistant from each other. The limiting grooves 6 are used to cooperate with the pins 8.
[0026] Furthermore, the front end of the pin 8 extends into the interior of the movable groove 5 and is movably connected to the movable groove 5. The two pins 8 are in contact with each other, and the pins 8 can play a role in locking and limiting.
[0027] Furthermore, each of the two pins 8 has a clamping spring 12 fixedly installed on its opposite side. The opposite sides of the two clamping springs 12 are fixedly connected to the inner wall of the connecting groove 7. The clamping spring 12 can drive the pins 8 to reset.
[0028] Working principle: When using this device, the user inserts the wire into the connecting post 2 through the through groove 10. Then, the user pulls the pin 8 to move it in the connecting groove 7. The movement of the pin 8 drives the fixed rod 3 to move, and the movement of the fixed rod 3 drives the pressure roller 4 to move and press against the wire. Then, the user locks the two pins 8 in the corresponding limiting grooves 6 for limiting. At the same time, the clamping spring 12 will apply a pulling force to the traction pin 8, making the pin 8 more stable, thereby completing the fixing of the wire.
[0029] Based on the above work process, we can conclude that:
[0030] The transformer uses hardware terminals that can fix the wires. By setting up pressure rollers 4, pins 8, limiting grooves 6 and fixing rods 3, the device adopts a snap-fit fixing design when in use. This allows users to fix the wires simply by pulling and snapping, bringing convenience to users, improving the practicality of the device and meeting the user's needs.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
