Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, specifically a self-locking double stud terminal block. Background Technology

[0002] Terminal blocks play a crucial role in the connection of electrical equipment. However, traditional terminal blocks have several drawbacks in practical use. Based on existing terminal block products on the market, ordinary terminal blocks may loosen wires due to vibration or external pulling, affecting the stability of the electrical connection and potentially causing poor contact, overheating, and other safety hazards. This deficiency is particularly pronounced in industrial equipment and power transmission lines where high reliability of electrical connections is required. Furthermore, the installation and removal of traditional terminal blocks are cumbersome, requiring multiple tightening and loosening of screws with tools, reducing work efficiency. Therefore, a self-locking double-stud terminal block is needed to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a self-locking double stud terminal block to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-locking double-stud terminal block, comprising a terminal body, two terminals, a self-locking mechanism, and a connector. The terminal body has an internal cavity to accommodate the terminals and parts of the self-locking mechanism. The two terminals are respectively disposed on both sides of the terminal body, each terminal comprising a column and a nut at the top of the column. The column has a threaded hole for connecting to a wire.

[0005] The self-locking mechanism includes a locking block, a spring, and a button. The locking block is disposed within a cavity of the terminal body and can slide within the cavity. One end of the locking block has a locking tooth that matches the threaded hole of the terminal post. When the locking block slides, the locking tooth can engage or disengage with the thread in the threaded hole of the terminal post. One end of the spring is connected to the locking block, and the other end is fixed to the inner wall of the terminal body, providing elastic force to the locking block in the direction of the terminal post. The button is disposed on the surface of the terminal body and connected to the locking block. Pressing the button controls the sliding of the locking block.

[0006] The connector is located at the bottom of the terminal body and is used to fix the terminal to the guide rail. The connector has a slot that matches the guide rail, and the slot has anti-slip protrusions to increase the friction between the connector and the guide rail, ensuring that the terminal is installed securely.

[0007] Preferably, the surface of the terminal block is provided with an insulating layer, which is made of rubber material, to effectively prevent short circuits between the terminals and improve the safety of the electrical connection.

[0008] Preferably, the surface of the button is provided with anti-slip texture to facilitate the operator to press the button and improve the convenience of operation.

[0009] Preferably, a guide groove and a guide block are provided between the locking block and the terminal body cavity. The guide groove is provided on the inner wall of the terminal body cavity, and the guide block is provided on the side of the locking block. The guide groove and the guide block cooperate with each other to ensure the stability of the locking block during the sliding process and prevent the locking block from shifting.

[0010] Compared with the prior art, this utility model provides a self-locking double stud terminal block, which has the following advantages:

[0011] 1. By setting a self-locking mechanism, after the wire is connected to the terminal block, the locking teeth can engage with the threads in the threaded hole of the terminal block to prevent the wire from loosening, which greatly improves the stability of the electrical connection and reduces the safety hazards caused by loose wires.

[0012] 2. The self-locking mechanism's button operation is convenient, requiring no additional tools. Locking and unlocking can be achieved simply by pressing the button, simplifying the wiring and disconnection process and improving work efficiency.

[0013] 3. The insulating layer on the surface of the terminal block can effectively prevent short circuits. The anti-slip protrusions on the connector and the guide structure of the locking block improve the stability of the terminal installation and the stability of the locking block sliding, respectively, further enhancing the performance and reliability of the product.

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.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Example:

[0023] Please see Figure 1-4This utility model provides a technical solution: a self-locking double stud terminal block, including a terminal body 1, two terminals 2, a self-locking mechanism 3, and a connecting seat 4. The terminal body 1 has an internal cavity. The two terminals 2 are respectively disposed on both sides of the terminal body 1. Each terminal 2 includes a column 21 and a nut 22 located at the top of the column 21. The column 21 has a threaded hole inside. The self-locking mechanism 3 includes a locking block 31, a spring 32, and a button 33. The locking block 31 is disposed within the cavity of the terminal body 1 and is slidable. One end of the locking block 31 has a locking tooth 311 that matches the threaded hole of the terminal 2. One end of the spring 32 is connected to the locking block 31. One end is fixed to the inner wall of the terminal body 1. The button 33 is disposed on the surface of the terminal body 1 and connected to the locking block 31. The connecting seat 4 is disposed at the bottom of the terminal body 1. The connecting seat 4 is provided with a slot 41 adapted to the guide rail. The slot 41 is provided with an anti-slip protrusion 411. The surface of the post 21 of the terminal 2 is provided with an insulating layer 5. The insulating layer 5 is made of rubber material. The surface of the button 33 is provided with anti-slip texture 331. A guide groove 6 and a guide block 61 are provided between the locking block 31 and the cavity of the terminal body 1. The guide groove 6 is disposed on the inner wall of the cavity of the terminal body 1. The guide block 61 is disposed on the side of the locking block 31. The guide groove 6 and the guide block 61 cooperate with each other.

[0024] Working principle: When connecting the wire, pressing button 33 pushes locking block 31 backward against the elastic force of spring 32, at which point the locking teeth 311 disengage from the threaded hole of terminal 2. After inserting the wire into the threaded hole of terminal 2, releasing button 33 causes the locking block 31 to move forward, and the locking teeth 311 re-engage with the threads in the threaded hole of terminal 2, thus locking the wire. Connector 4 is mounted on guide rail via slot 41, and anti-slip protrusion 411 increases friction with guide rail, ensuring stable terminal installation. Insulation layer 5 on the surface of terminal 2 prevents short circuits between terminal 2, and guide groove 6 and guide block 61 ensure that locking block 31 remains stable during sliding.
