Description

Technical Field

[0001] This utility model relates to the field of electronic and electrical technology, and in particular to a novel terminal block. Background Technology

[0002] A terminal block is a metal plate encased in insulating plastic. It has holes at both ends for inserting wires and screws for tightening or loosening. It facilitates wire connection without soldering or winding, allowing for easy disconnection or connection, and is suitable for interconnecting large numbers of wires. However, terminal blocks are typically installed using screws, which heavily relies on manual tightening force. Insufficient force can lead to increased contact resistance and overheating, while excessive force can damage the screws or terminals. Prolonged vibration can also cause loosening. Furthermore, when wiring a large number of wires, each terminal block needs to be screwed on individually, which is time-consuming and labor-intensive. Later maintenance or wire replacement requires disassembly, especially on densely packed terminal blocks where space is limited, further reducing efficiency. When a single terminal fails, a small screwdriver is needed to pry open the clips on both sides of the terminal before removing it, which is cumbersome and impacts overall efficiency.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example: This example provides a novel terminal block, see [link to example]. Figure 1-4 The system includes a base 1 that serves as a support. The base 1 is a support seat that integrates multiple terminals in a linear arrangement. The outer side of the base 1 is wrapped with an insulating sleeve 4. The insulating sleeve 4 is made of flexible insulating material, which can prevent the base 1 from being damaged due to accidental bumps. The insulating sleeve 4 also wraps around both ends of the metal mounting plate 301, so that the metal mounting plate 301 will not fall off the base 1. The base 1 is provided with two sets of symmetrical terminals. The terminals include clamping members 2 and sliding members 3. The clamping members 2 facilitate the installation or removal of wires, and the sliding members 3 facilitate the replacement of terminals. The sliding members 3 include a metal mounting plate 301, which is set on the base 1. The metal mounting plate 301 is rectangular. The clamping members 2 include a metal clamping plate 201, which is set on the base 1. The metal clamping plate 201 is Z-shaped. The clamping component 2 also includes a serpentine spring 204, which is horizontally positioned between the metal clamping plate 201 and the metal mounting plate 301. It is used to provide sufficient clamping force to the metal clamping plate 201 and the metal mounting plate 301 to ensure that the metal clamping plate 201 can be firmly attached to the metal mounting plate 301. The serpentine spring 204 has a long strip structure that can match the width of the metal clamping plate 201 and the metal mounting plate 301 to ensure that the clamping force is evenly distributed. It can be easily pried open and provides sufficient clamping force. It will not fail due to excessive deformation, nor will it be difficult to use due to excessive elasticity. The two ends of the metal clamping plate 201 are located on different horizontal planes. The bottom surface of the lower end of the metal clamping plate 201 contacts the top surface of the metal mounting plate 301. The clamping member 2 also includes a pair of first protrusions 202. The pair of first protrusions 202 are fixedly disposed on the bottom surface of the upper end of the metal clamping plate 201. A connecting shaft 203 is inserted through the pair of first protrusions 202. A serpentine spring 204 is sleeved on the connecting shaft 203, and the two extended ends of the serpentine spring 204 abut against the bottom surface of the metal clamping plate 201 and the top surface of the metal mounting plate 301, respectively. When it is necessary to clamp the wire, the serpentine spring 204 releases elastic potential energy under the action of elastic restoring force, generating a reverse pulling or pushing force on the metal clamping plate 201 and the metal mounting plate 301, so that the wire can be clamped by the metal clamping plate 201 and the metal mounting plate 301. The top surface of the lower end of the metal clamping plate 201 is fixedly provided with a fixing plate 205, which is inverted U-shaped. The fixing plate 205 makes it easier for the metal clamping plate 201 to be lifted. This novel terminal block, through the inclusion of a clamping element 2, facilitates the inspection or replacement of wires. The serpentine spring 204 ensures a uniform distribution of clamping force between the metal clamping plate 201 and the metal mounting plate 301, allowing for easy opening while providing sufficient clamping force. It avoids failure due to excessive deformation or excessive elasticity that would cause strain. No screws are required for installation; simply lifting and loosening the fixing plate 205 allows for easy inspection or replacement of wires, significantly improving work efficiency.

[0016] In the specific implementation process, such as Figure 1 , Figure 3 and Figure 4 As shown, the sliding member 3 also includes two sets of symmetrically arranged slots 303 on the base 1. Each set of slots 303 has multiple slots, and the number of slots 303 is equal to that of the metal mounting plates 301. The multiple slots 303 are arranged in a horizontal array. Each metal mounting plate 301 is set in the corresponding slot 303. Protrusions 302 are fixed on both sides of the metal mounting plate 301. Sliding grooves are opened on the inner walls of both sides of the slot 303. The protrusions 302 slide in the corresponding sliding grooves, so that the metal mounting plate 301 can slide on the base 1, which is convenient for pulling out and putting in, thereby facilitating the replacement of the terminals. A pair of second protruding plates 304 are fixedly provided on the top surface of the metal mounting plate 301. The second protruding plates 304 are coaxially arranged with the first protruding plate 202. The two ends of the connecting shaft 203 pass through the first protruding plate 202 and are rotatably connected to the second protruding plates 304. The second protruding plates 304 can restrict the position of the connecting shaft 203, so that the connecting shaft 203 can only rotate along the axis of the second protruding plate 304, thereby preventing the clamping surfaces of the metal clamping plate 201 and the metal mounting plate 301 from shifting. The novel terminal block of this utility model, by setting a sliding member 3, realizes the function of easy replacement of the terminal. Under the action of the protrusion 302, the metal mounting plate 301 can be pulled out from the base 1, thereby allowing the terminal to be replaced, which is convenient for workers to use and significantly improves the efficiency of use.

[0017] Specifically, the working principle and operation method of this utility model are as follows: In specific operations, the procedures are as follows; Step 1: When installing the wire, lift the fixing plate 205 upwards, causing the lower end of the metal clamping plate 201 to move upwards. This causes the upper end of the metal clamping plate 201 and the metal mounting plate 301 to exert a squeezing force on the serpentine spring 204, creating a gap between the contact surfaces of the metal clamping plate 201 and the metal mounting plate 301. Place the wire into the gap between the metal clamping plate 201 and the metal mounting plate 301. Release the fixing plate 205. Under the action of the elastic restoring force, the serpentine spring 204 releases its elastic potential energy, generating a reverse pulling or pushing force on the metal clamping plate 201 and the metal mounting plate 301, causing the wire to be clamped by the metal clamping plate 201 and the metal mounting plate 301. Step 2: When a terminal malfunctions and needs to be replaced, remove the insulating sleeve 4 from the base 1 and pull the fixing plate 205 outward. Since the first protrusion 202 and the second protrusion 304 are both connected to the connecting shaft 203, when the fixing plate 205 moves the metal clamping plate 201 outward, the metal mounting plate 301 moves with the metal clamping plate 201. Under the action of the protrusion 302, the metal mounting plate 301 can be pulled out from the base 1. After replacing the terminal, repeat the above steps to insert the metal mounting plate 301 into the base 1.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this solution, "multiple" means two or more, unless otherwise explicitly specified.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
