Description

Technical Field

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

[0002] Terminal blocks play a crucial role in the installation of numerous electrical devices, circuit wiring, and various electrical connection scenarios, ensuring reliable connections between wires or between wires and electrical components. Traditionally, terminal blocks are mostly secured by screws. This requires using tools such as screwdrivers to strip the wire core, insert it into the terminal block, and then tighten the screw to apply pressure to the core, ensuring a stable electrical connection.

[0003] This traditional wiring method, relying on screw tightening, reveals numerous problems when faced with multi-threaded wiring requirements. First, it's inefficient; tightening the screws for each wire connection takes time, resulting in a very long overall time for a large number of connections, severely impacting project progress. Second, it demands a high level of skill from operators; improper screw tightening can lead to weak connections, resulting in loose connections, overheating, arcing, and other safety hazards, affecting the normal operation of the entire circuit system. Furthermore, the screw-tightening process is extremely cumbersome when frequent disconnection or rewiring is needed for circuit adjustments and maintenance, hindering rapid circuit maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-threaded terminal block, comprising a housing and a bottom cover, the housing and the bottom cover being fixedly connected, the top of the housing being provided with an upper insertion hole and a button, the bottom of the bottom cover being provided with a lower insertion hole, a spring sheet being provided inside the housing, the bottom end of the button abutting against the upper surface of the spring sheet, the right end of the spring sheet being located below the upper insertion hole, and a pressure plate being provided inside the lower insertion hole.

[0006] Preferably, there are two pressure plates, which are symmetrically distributed inside the lower insertion hole. The middle part of each pressure plate near the bottom is an arc-shaped protrusion, and the arc-shaped protrusions on the two pressure plates are opposite to each other.

[0007] Preferably, both the spring and the pressure plate are made of high-precision phosphor bronze.

[0008] Preferably, the outer shell and the bottom cover are made of the same material, and both are made of insulating plastic material.

[0019] 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.

[0020] 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.

[0021] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a technical solution: a multi-threaded terminal block, including a housing 1 and a bottom cover 2, the housing 1 and the bottom cover 2 are fixedly connected, the top of the housing 1 is provided with an upper insertion hole 3 and a button 5, the bottom of the bottom cover 2 is provided with a lower insertion hole 4, the inside of the housing 1 is provided with a spring piece 6, the bottom end of the button 5 abuts against the upper surface of the spring piece 6, the right end of the spring piece 6 is located below the upper insertion hole 3, the inside of the lower insertion hole 4 is provided with a pressure plate 7, there are two pressure plates 7, the two pressure plates 7 are symmetrically distributed inside the lower insertion hole 4, the middle part of the pressure plate 7 near the bottom end of the pressure plate 7 is an arc-shaped protrusion structure, and the arc-shaped protrusions on the two pressure plates 7 are opposite to each other, the spring piece 6 and the pressure plate 7 are both made of high-precision phosphor bronze, the housing 1 and the bottom cover 2 are made of the same material, and are both made of insulating plastic material, the pressing surface of the button 5 is provided with a groove.

[0022] In this embodiment, a spring piece 6 is provided inside the outer casing 1, with its right end located below the upper insertion hole 3. The bottom of the button 5 on the outer casing 1 contacts the upper surface of the spring piece 6. Symmetrical pressure plates 7 are provided inside the lower insertion hole 4. When installing the wire, pressing the button 5 controls the movement of the spring piece 6. After inserting the wire end into the upper insertion hole 3, releasing the button 5 quickly clamps the wire inserted into the upper insertion hole 3. When inserting the wire end into the lower insertion hole 4, the wire is clamped by the protrusions on the two pressure plates 7. This fixing method enables quick clamping or loosening of the wire, making the operation simple and fast, eliminating the traditional screw tightening method, and significantly improving wiring efficiency. The two symmetrically distributed pressure plates 7 form a specific clamping structure inside the lower insertion hole 4. When the wire is inserted into the lower insertion hole 4... The arc-shaped protrusion of the pressure plate 7 allows it to fit tightly against the surface of the wire, thereby increasing the clamping force and making the wire more securely fixed. The high-precision phosphor bronze material used for the spring plate 6 and pressure plate 7 utilizes the excellent conductivity of phosphor bronze to ensure smooth current transmission within the terminal block, reducing power loss. High-precision phosphor bronze also has good elasticity and corrosion resistance, allowing the spring plate 6 and pressure plate 7 to maintain stable elasticity during long-term use, preventing deformation and ensuring continuous clamping force on the wire, while also extending their service life. The outer shell 1 and bottom cover 2 are made of insulating plastic material, effectively preventing electric shock accidents and ensuring operator safety. The groove on the pressing surface of the button 5 provides a certain degree of anti-slip effect, effectively preventing operational errors caused by finger slippage in humid or oily environments, ensuring the normal use of the terminal block.

[0023] Example 2: As Figure 3 As shown, the surface of the outer shell 1 is provided with a slot 9, and a right-angled buckle 10 is fixedly connected to the bottom cover 2 at the position corresponding to the slot 9. The buckle 10 is locked inside the slot 9.

[0024] In this embodiment, the bottom cover 2 and the outer shell 1 can be connected by a snap-fit ​​10. This connection method facilitates installation and disassembly. When it is necessary to inspect, repair or replace parts of the internal structure, the operator only needs to use a tool to press the snap-fit ​​10 to disassemble the bottom cover 2, which further improves the convenience of use.

[0025] The working principle of this embodiment is as follows: During use, the operator first strips a certain length of the insulation from the wire to be connected, exposing the core wire. Then, the core wire is inserted into the upper insertion hole 3. At this time, the spring piece 6 is in its natural state, with its right end positioned below the upper insertion hole 3. Next, the operator presses the button 5. The bottom of the button 5 applies pressure to the upper surface of the spring piece 6, causing it to elastically deform and move downwards at its right end. The core wire is then inserted, and the button 5 is released. At this time, the right end of the spring piece 6 returns to its original position under its own elasticity and firmly presses against the inserted wire core wire, thus achieving a reliable connection between the wire and the internal conductive structure of the terminal block. Similarly, for wires that need to be connected from the bottom, the insulation is also stripped before insertion into the lower insertion hole 4. Two symmetrically arranged pressure plates 7 inside the lower insertion hole 4 have arc-shaped protrusions that interact with the surface of the wire during insertion. The contact surfaces are tightly closed, and the elasticity of the pressure plates 7 creates a clamping force on the wire, further securing it and ensuring that it will not easily shift during use, thus guaranteeing the stability of the connection. When it is necessary to disconnect the wire, the operator presses the button 5 again, causing the spring plate 6 to deform further, separating its right end from the wire core and releasing the clamping force on the wire. At this point, the operator can easily pull the wire out of the upper insertion hole 3. For the wire in the lower insertion hole 4, due to the elastic design of the pressure plates 7, only a little force is needed to pull the wire out. The arc-shaped protrusion structure of the pressure plates 7 will not excessively restrict the wire, facilitating wire disassembly. If it is necessary to separate the outer casing 1 from the bottom cover 2 for internal component maintenance, the operator only needs to use a tool to press the buckle 10 to disassemble the bottom cover 2, further improving the convenience of use.

[0026] 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.
