A switch terminal to prevent wire damage

Abstract

This utility model belongs to the field of switch terminal technology and discloses a switch terminal that prevents wire damage. It includes a switch terminal body, a mounting plate detachably mounted on the bottom of the switch terminal body, a fixing seat fixedly connected to the bottom surface of the mounting plate, and two opposing wire-passing grooves on the front of the fixing seat. A wire-blocking plate is fixedly connected to the inner wall of each of the two wire-passing grooves. This utility model allows the wire to be pressed and pushed into the wire-passing groove, making the wire U-shaped and passing through the bottom of the wire-blocking plate. Then, by moving an L-shaped insert downwards, the L-shaped insert squeezes and limits the wire in the wire-passing groove, thus securing the wire firmly between the wire-passing groove and the wire-blocking plate. When the wire is accidentally pulled, the wire-blocking plate and the wire-passing groove disperse the pulling force, preventing the pulling force from acting directly on the terminal, thereby solving the problem of pulling damage between the wire and the terminal of the switch terminal body.

Description

Technical Field

[0001] This utility model belongs to the field of switch terminal technology, specifically a switch terminal that prevents damage to wires. Background Technology

[0002] Switch terminals are designed for use with various miniature circuit breakers, residual current circuit breakers, air switches, etc., and are used for wiring in complete sets of electrical control and distribution equipment and modular terminal electrical boxes.

[0003] A search revealed that patent CN222826324U discloses an overload protection switch terminal, including a housing with a mounting mechanism. A piston seat is fixedly mounted on the inner left side of the housing, and a piston chamber is formed within the piston seat. Hydraulic oil is contained within the piston chamber, and a pushing mechanism is also provided within the piston chamber. A terminal is located on the left side of the housing. This application has the following advantages and effects: By incorporating a pushing mechanism, the hydraulic oil, when heated and expanded, pushes the piston plate and push rod to the right, thereby separating the moving contact from the stationary contact and cutting off the circuit, achieving the purpose of overload protection. Furthermore, the inclusion of a spring allows the spring to pull the push rod and piston plate to the left, restoring the moving contact to contact the stationary contact again and restoring the circuit to its conductive state. This enables the switch terminal to be automatically energized, facilitating its use.

[0004] Analysis of the above technical solutions reveals that, since the wire is directly connected to the terminal block of the switch, the connection point is easily damaged when the wire is accidentally pulled, making it difficult to guarantee the tightness of the connection between the wire and the terminal block. Therefore, we provide a switch terminal that prevents wire damage to solve the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a switch terminal that prevents damage to wires.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a switch terminal for preventing wire damage, comprising a switch terminal body, a mounting plate detachably disposed at the bottom of the switch terminal body, a fixing seat fixedly connected to the bottom surface of the mounting plate, two opposing wire-passing grooves opened on the front side of the fixing seat, a wire-blocking plate fixedly connected to the inner wall of each of the two wire-passing grooves, and a positioning mechanism for limiting the wires provided in each of the two wire-passing grooves.

[0007] Preferably, the positioning mechanism includes a mounting groove, which is formed on the inner top wall of the wire-passing groove and extends to the front of the fixing seat. An L-shaped insert rod is slidably disposed in the mounting groove, and the bottom end of the L-shaped insert rod is inclined.

[0008] Preferably, both sides of the L-shaped insert are provided with anti-slip rods arranged at equal intervals, and the anti-slip rods are in contact with the inner wall of the mounting groove.

[0009] Preferably, both ends of the mounting plate are detachably connected to the bottom surface of the switch terminal body by screws.

[0010] Preferably, the mounting plate has a clearance groove that matches the wiring terminal at the bottom of the switch terminal body, and the fixing seat is fitted onto the wiring terminal at the bottom of the switch terminal body through the clearance groove.

[0011] Preferably, the inner walls of the two threading grooves and one side of the wire-blocking plate are all fixedly connected with anti-slip strips arranged at equal intervals.

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

[0013] This invention, through the coordinated arrangement of a mounting plate, a fixing base, a wire-passing groove, a wire-blocking plate, and a positioning mechanism, can press and push the wire into the wire-passing groove, making the wire in the groove U-shaped and passing through the bottom of the wire-blocking plate. Then, by moving the L-shaped plug downwards, the L-shaped plug squeezes and limits the wire in the wire-passing groove, thus securing the wire firmly between the wire-passing groove and the wire-blocking plate. When the wire is accidentally pulled, the wire-blocking plate and the wire-passing groove will disperse the pulling force, preventing the pulling force from acting directly on the terminal. This solves the problem of pulling damage between the wire and the terminal of the switch body, making operation easier and more convenient. Moreover, the device has a simple structure and is easy to assemble and disassemble. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] like Figure 1-4 As shown, this embodiment proposes a switch terminal to prevent wire damage, including a switch terminal body 1. A mounting plate 2 is detachably provided on the bottom of the switch terminal body 1. The mounting plate 2 can be easily assembled on the bottom of the switch terminal body 1. A fixing seat 3 is fixedly connected to the bottom surface of the mounting plate 2. The fixing seat 3 is located between two terminals at the bottom of the switch terminal body 1. Two opposing wire-passing grooves 4 are opened on the front of the fixing seat 3. A wire-blocking plate 6 is fixedly connected to the inner wall of each of the two wire-passing grooves 4. A positioning mechanism for limiting the wire is provided in each of the two wire-passing grooves 4. With the above structure, when the wire is connected to the terminal at the bottom of the switch terminal body 1, it can be passed into the wire-passing groove 4 and placed inside the wire-blocking plate 6, so that the part of the wire in the wire-passing groove 4 is U-shaped, thereby effectively preventing the wire from being pulled at will and avoiding damage between the wire and the terminal. Finally, the positioning mechanism tightly limits the wire in the wire-passing groove 4, preventing the wire from sliding out of the wire-passing groove 4 at will.

[0021] like Figures 1 to 4 As shown, the positioning mechanism includes a mounting groove 7, which is formed on the inner top wall of the wire threading groove 4 and extends to the front of the fixing seat 3. An L-shaped plug 8 is slidably disposed in the mounting groove 7, and the bottom end of the L-shaped plug 8 is beveled. With the above structure, when the wire is passed between the wire threading groove 4 and the wire stop plate 6, the L-shaped plug 8 can be pushed down so that the L-shaped plug 8 can squeeze and limit the wire in the wire threading groove 4, thereby preventing the wire between the wire threading groove 4 and the wire stop plate 6 from accidentally slipping out. In addition, the length of the L-shaped plug 8 is less than the length of the mounting groove 7, so the L-shaped plug 8 can be easily pulled out of the mounting groove 7 for replacement.

[0022] like Figure 4 As shown, anti-slip rods 10 are arranged at equal intervals on both sides of the L-shaped plug 8, and the anti-slip rods 10 are in contact with the inner wall of the mounting groove 7. The anti-slip rods 10 ensure that the L-shaped plug 8 will not slide freely in the mounting groove 7, and increase the contact friction between the L-shaped plug 8 and the mounting groove 7, so as to ensure the positioning effect of the L-shaped plug 8 on the wire in the wire groove 4.

[0023] like Figure 2As shown, the two ends of the mounting plate 2 are detachably connected to the bottom surface of the switch terminal body 1 by screws, which can easily fix the mounting plate 2 to the bottom surface of the switch terminal body 1 without affecting the normal connection of the wires. When this component is damaged, it can be easily removed and replaced.

[0024] like Figures 2 to 4 As shown, the mounting plate 2 has a relief groove 9 that matches the wiring terminal at the bottom of the switch terminal body 1, and the fixing seat 3 is fitted onto the wiring terminal at the bottom of the switch terminal body 1 through the relief groove 9. With the relief groove 9, the mounting plate 2 can be properly fixed at the bottom of the switch terminal body 1, and it also has a limiting effect on the mounting plate 2 to prevent the mounting plate 2 from sliding at the bottom of the switch terminal body 1.

[0025] like Figures 1 to 4 As shown, anti-slip strips 5 are fixedly connected to the inner walls of the two wire grooves 4 and one side of the wire baffle 6 at equal intervals. The anti-slip strips 5 enhance the contact friction between the wire grooves 4 and the wire baffle 6, thereby preventing the wire from being easily pulled downwards. In addition, the anti-slip strips 5 are shaped like barbs pointing upwards. In order to avoid the anti-slip strips 5 damaging the wire sheath, the anti-slip strips 5 can be made of rubber.

[0026] The working principle and usage process of this utility model are as follows: Connect the wire to the terminal block at the bottom of the switch terminal body 1, then press and push the wire into the wire groove 4, so that the wire in the wire groove 4 is U-shaped and passes through the bottom of the wire stop plate 6. Then, move the L-shaped plug 8 downwards, so that the L-shaped plug 8 squeezes and limits the wire in the wire groove 4, so that the wire can be firmly fixed between the wire groove 4 and the wire stop plate 6, which solves the problem of pulling damage between the wire and the terminal block of the switch terminal body 1, and makes the operation easier and more convenient.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0028] 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.
