Through-type terminals are usually made of highly conductive metal materials such as copper or aluminum, which can withstand large currents and avoid power loss and heat generation caused by excessive resistance. There are various types of through-type terminals on the market, including terminals with different connection methods such as plug-in type, screw type, and quick wiring, to meet the wiring requirements in different environments. In power transmission and distribution systems, through-type terminals are widely used to connect various cables and wires to ensure the stable transmission of electricity. In industrial control systems, such terminals are often used to connect the circuits of devices such as sensors and actuators, which can not only ensure the accurate transmission of signals but also improve the safety, reliability, and stability of the devices;
[0003] During the actual use of the terminal, when inserting a wire into the terminal and locking and fixing the wire, the wire is relatively slippery and prone to relative movement with the terminal, making it difficult to install and fix the wire, resulting in wiring failure of the power terminals, wire terminals, and terminal device terminals in the circuit. Moreover, when installing multiple terminals, it is impossible to install and splice multiple terminals, reducing the flexibility of the terminal's use. In view of this, we propose a through-type terminal. Summary of the Utility Model

An installation post is fixedly connected to the upper surface of the terminal body. A groove is provided on the surface of the installation post, and a pre-tightening component is arranged inside the groove. An installation block is fixedly connected to the upper surface of the terminal body. A threaded groove is provided on the surface of the installation block, and a fastening member is arranged inside the threaded groove. Among them: the interiors of the installation post and the installation block are both cavities;
[0006] One side surface of the terminal body is fixedly connected with an installation plate. Limiting grooves are provided on both opposite side surfaces of the installation plate.

On the contrary, rotating the adjusting plate upward can make the pressing block disengage from the pre-tightening of the wire through the extrusion spring, realizing quick disassembly; the mounting plates and mounting frames installed on two adjacent terminal body cooperate. By pulling the horizontal block to make the limiting block disengage from the limiting groove and enter the inside of the limiting cylinder, the disassembly of the two terminal bodies can be realized.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0020] A through-type terminal is an electrical component used to connect electronic devices. It can connect the power terminals, wire terminals, and terminal device terminals in a circuit. Through-type terminal blocks are usually made of highly conductive metal materials such as copper or aluminum, which can withstand large currents and avoid power loss and heat generation caused by excessive resistance. There are various types of through-type terminal blocks on the market, including terminal blocks with different connection methods such as pluggable, screw-type, and quick connection, to meet the wiring requirements in different environments. In power transmission and distribution systems, through-type terminal blocks are widely used to connect various cables and wires to ensure the stable transmission of electricity. In industrial control systems, such terminal blocks are commonly used to connect the circuits of devices such as sensors and actuators, which can not only ensure the accurate transmission of signals but also improve the safety, reliability, and stability of the devices.
[0021] Please refer to Figures 1 - 3As shown in the figure, this embodiment provides a through-type terminal, including a terminal body 1. Considering that during the actual use of the terminal body 1, when inserting a wire into the terminal body 1 and locking and fixing the wire, the wire is relatively slippery and prone to relative movement with the terminal body 1, making it difficult to install and fix the wire, resulting in the failure of wiring of the power terminal, wire terminal, and terminal device terminal in the circuit. Moreover, when installing multiple terminals, it is impossible to install and splice multiple terminals, reducing the flexibility of using the terminal body 1. Therefore, specifically as follows: A placement groove 10 is formed on the surface of the terminal body 1, an installation post 11 is fixedly connected to the upper surface of the terminal body 1, a groove is formed on the surface of the installation post 11, and a pre-tightening assembly 2 is arranged inside the groove. An installation block 12 is fixedly connected to the upper surface of the terminal body 1, a threaded groove is formed on the surface of the installation block 12, and a fastener 3 is arranged inside the threaded groove. Among them: The interiors of both the installation post 11 and the installation block 12 are cavities;
[0022] One side surface of the terminal body 1 is fixedly connected to an installation plate 13, limiting grooves 131 are formed on both opposite side surfaces of the installation plate 13, the other side surface of the terminal body 1 is fixedly connected to an installation frame 14, limiting cylinders 140 are installed on both opposite surfaces of the installation frame 14, and a limiting mechanism 4 is installed inside the limiting cylinder 140. Among them: The limiting groove 131 is adapted to cooperate with the limiting mechanism 4.
[0023] The improvement of this embodiment lies in:
[0024] The pre-tightening assembly 2 first limits and pre-tightens the wire to prevent the wire from moving during subsequent fastening, resulting in wiring failure; the installation plates 13 and installation frames 14 of adjacent two terminal bodies 1 cooperate, and by controlling the limiting mechanism 4, the installation and disassembly of multiple terminal bodies 1 can be realized, improving the flexibility of using the terminal body 1.
[0025] Considering that during the actual use of the terminal block, when inserting a wire into the terminal block and locking and fixing the wire, the wire is relatively slippery and prone to relative movement with the terminal block body 1, making it difficult to install and fix the wire. Therefore, it is necessary to pre-tighten the wire first. Thus, the pre-tightening assembly 2 includes a support rod 20 and a pressing block 21. The support rod 20 consists of a cylindrical section and a flat section. An extrusion spring 201 is provided on the outer wall of the support rod 20. Among them: the top end of the extrusion spring 201 is fixedly connected to the inner top end of the mounting post 11, and the bottom end of the extrusion spring 201 is fixedly connected to the upper surface of the pressing block 21. A connecting rod 202 penetrates through the side wall of the top end of the support rod 20, and an adjusting plate 203 is hinged to the shaft side of the connecting rod 202. By rotating the adjusting plate 203 downward, the support rod 20 moves downward, so that the pressing block 21 connected to the support rod 20 presses down to limit the wire first, and the wire is pre-tightened and limited first to prevent the wire from moving during subsequent fastening of the wire, resulting in wiring failure. On the contrary, rotating the adjusting plate 203 upward can make the pressing block 21 disengage from the pre-tightening of the wire through the extrusion spring 201, realizing quick disassembly.
[0026] Secondly, the fastener 3 includes an adjusting rod 30. The adjusting rod 30 is set as a threaded rod structure and is in threaded cooperation with the threaded groove. A fixing block is installed on the lower surface of the adjusting rod 30. After pre-tightening the wire in advance, the fixing block is used to fix the wire by rotating the adjusting rod 30.
[0027] Considering the installation and disassembly of multiple terminal block bodies 1 to improve their flexibility, the limiting mechanism 4 includes a connecting shaft 40 and a limiting block 41. A return spring 402 is provided on the shaft side of the connecting shaft 40. Among them: the top end of the return spring 402 is fixedly connected to the inner top end of the limiting cylinder 140, and the bottom end of the return spring 402 is fixedly connected to the upper surface of the limiting block 41. A lying block 401 is fixedly connected to the top end of the connecting shaft 40. By pulling the lying block 401, the limiting block 41 is disengaged from the limiting groove 131 and enters the inner part of the limiting cylinder 140, and the disassembly of the two terminal block bodies 1 can be realized. On the contrary, releasing the lying block 401, the elasticity of the return spring 402 will pop the limiting block 41 into the inner part of the limiting groove 131 to limit its installation, and the installation and splicing of multiple terminals can be realized.
[0028] In order to adapt to wires of different sizes, shapes and sizes, the lower surface of the placement groove 10 is set to be arc-shaped, and an arc-shaped groove is formed on the surface of the pressing block 21. A number of rubber bumps 210 are arranged inside the arc-shaped groove to adapt to wires of different sizes, shapes and sizes and increase the friction force when the wire is inserted, thereby improving the connection stability.
[0029] Considering that it is necessary to pre-tighten and limit the wire first and then fix and wire the wire, the mounting block 12 is arranged behind the mounting post 11.
[0030] When the through-type terminal of the utility model is specifically used, the user inserts the wire into the interior of the placement groove 10 until it reaches the fastener 3. A number of rubber bumps 210 can increase the friction force when the wire is inserted. By rotating the adjusting plate 203 downward, the support rod 20 moves downward, so that the pressure block 21 connected to the support rod 20 presses down to limit and pre-tighten the wire first, avoiding wire movement during subsequent wire fastening and resulting in wiring failure. Then, rotate the adjusting rod 30 to fix the wire by the fixing block. On the contrary, rotating the adjusting plate 203 upward can make the pressure block 21 disengage from the pre-tightening of the wire by squeezing the spring 201, realizing the rapid disassembly of the wire; if you want to install and disassemble multiple terminal body 1, the mounting plates 13 and mounting brackets 14 installed on adjacent two terminal body 1 cooperate. By pulling the lying block 401, the limiting block 41 disengages from the limiting groove 131 and enters the interior of the limiting cylinder 140, then the disassembly of the two terminal body 1 can be realized. On the contrary, releasing the lying block 401, the elasticity of the reset spring 402 will spring the limiting block 41 into the interior of the limiting groove 131 to limit and install it, and the installation and splicing of multiple terminals can be realized, improving the flexibility of the use of the terminal body 1.
