Description

Technical Field

[0001] This utility model relates to the field of wiring technology, and in particular to a single-piece terminal block. Background Technology

[0002] In the field of electrical connections, single-piece terminal blocks are a commonly used basic electrical component, widely used in the internal circuit connections of various electrical equipment, and in household and industrial electrical wiring. Their main function is to achieve a reliable connection between wires and other electrical components. Traditionally, single-piece terminal blocks mostly use screws to connect wires. During operation, a tool (such as a screwdriver) is needed to loosen the screws, strip the wire core, insert it into the terminal block, and then tighten the screws to apply pressure to the core to ensure the stability of the electrical connection. When it is necessary to remove the wire, the screws must be loosened again before the wire can be pulled out.

[0003] However, with the continuous development of modern electrical systems and the increasing demands for efficiency in electrical installation and maintenance, this traditional screw-fixing and disassembly method has revealed many shortcomings. From an operational efficiency perspective, whether installing or removing wires, tools are needed to tighten or loosen screws each time, a cumbersome and time-consuming process. This is especially true in situations requiring frequent circuit adjustments, equipment maintenance, or temporary electrical system setups, such as temporarily arranging circuits for numerous lighting devices at exhibitions or regularly maintaining and replacing wires on automated production lines. In these cases, the time spent on installing and removing wires using traditional single-piece terminal blocks can severely impact overall work progress, leading to increased labor costs and low work efficiency. Utility Model Content

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a technical solution: a single-piece terminal block, including a housing 1, on which are provided a first insertion hole 2, a second insertion hole 3, a first button slot 10 and a second button slot 11. A first button 4 and a second button 5 are provided inside the first button slot 10 and the second button slot 11. A first spring 8 and a second spring 9 are provided inside the housing 1. The right end of the first spring 8 is located directly below the first insertion hole 2, and the left end of the second spring 9 is located directly below the second insertion hole 2. The bottom end of the first button 4 abuts against the first spring 8, and the bottom end of the second button 5 abuts against the second spring 9. The first spring 8 and the second spring 9 are both made of copper, and the housing 1 is made of a high-temperature resistant insulating material.

[0021] In this embodiment, by setting a button and spring structure, when it is necessary to connect or disconnect the wire, simply press the corresponding button with a tool. This fixing method enables quick clamping or loosening of the wire, eliminating the need for traditional screw tightening and avoiding the impact on the overall work progress caused by the time spent on wire installation and removal, thus reducing labor costs. Springs 8 and 9 are made of copper, which has good conductivity, ensuring that the current can pass through the terminal block stably and smoothly when the wire is connected, ensuring high-quality electrical connection and meeting the electrical connection performance requirements of various electrical equipment internal circuit connections, household and industrial electrical wiring scenarios. The outer shell 1 is made of high-temperature resistant insulating material, so that even in high-temperature environments or when heat is generated by electrical use, the outer shell 1 will not be damaged or deformed due to high temperatures. At the same time, its insulation performance can prevent users from accidentally touching the internal conductive parts and causing electric shock, thus improving the safety of the entire terminal block.

[0022] Example 2: As Figure 4 As shown, the pressing surfaces of button 1 4 and button 2 5 are respectively provided with groove 1 6 and groove 2 7, and the surfaces of spring 1 8 and spring 2 9 are both tin-plated.

[0023] In this embodiment, by creating grooves 6 and 7 on the pressing surfaces of button 4 and button 5, the flathead screwdriver can be limited when it is pressed against button 4 and button 5 to prevent slippage. The surfaces of spring 8 and spring 9 are tin-plated, which forms a protective film on the surface of the spring, effectively preventing oxidation and extending the service life of the spring.

[0024] The working principle of this embodiment is as follows: When this single-piece terminal block is in operation, it mainly relies on the cooperation between the button and the spring to connect and disconnect the wire. When it is necessary to insert a wire for connection, for example, to insert the wire into the insertion hole 2, the button 4 is pressed by inserting a flat-head screwdriver into the groove 6 on the button 4. After the button 4 is subjected to force, it will slide inward inside the button groove 10 and press the spring 8 that is in contact with it. The spring 8 deforms under the pressure of the button 4. The end of the spring 8, which was originally located directly below the insertion hole 2, will be displaced, thus making room. At this time, the core wire of the wire is inserted through the insertion hole 2. Then the button 4 is released, and the spring 8 returns to its initial position by its own elastic restoring force. The spring 8 firmly presses down on the inserted wire core, ensuring the stability of the electrical connection between the wire and the terminal block through the elastic pressure of the spring. Similarly, when inserting the wire into the socket 3, pressing button 5 causes the spring 9 to deform, creating space for the wire to be inserted into the socket 3. After inserting the wire, releasing button 5 allows the spring 9 to return to its original shape and press down on the wire core, achieving a reliable electrical connection. When it is necessary to remove the wire, simply press the corresponding button again to deform the spring and release the pressure on the wire core, allowing the wire to be easily pulled out. The entire process does not require the use of tools or cumbersome operations such as screwing, making it convenient and efficient. This working principle enables quick and reliable connection and disconnection between the wire and the terminal block.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
