Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, specifically to an improved structure of a terminal block. Background Technology

[0002] Currently, existing terminal blocks typically use screw clamping. When using traditional terminal blocks, the fastening screws must first be loosened to create a gap between the terminal block and the wire harness before inserting the wire harness and tightening the screws to clamp the wire harness and prevent it from falling out.

[0003] However, this process has many drawbacks. When the wire harness is made of a single, relatively thick copper wire, the copper wire is soft, and the tightening screw can easily damage it during tightening. This damage manifests as mechanical damage to the copper wire, making it brittle, or leaving obvious screw marks at the tightened area, with the cross-section changing from cylindrical to square, and the cross-sectional area changing significantly. If the wire harness is made of multiple strands of copper wire, the tightening screw can loosen the copper wires during tightening. Moreover, to better secure the wire harness, workers often bend it before installing it inside the wiring section, which is not only cumbersome but also introduces uncontrollable factors.

[0004] Therefore, an improved structure for the terminal block is proposed. Utility Model Content

By adopting different structural designs for the fastening components and using different connection methods with the base, the installation and removal of the wire can be achieved by clamping or loosening it.

[0020] The technical solutions of the present utility model will now be described with reference to the accompanying drawings of the embodiments. The embodiments described below 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 skilled in the art without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides an improved structure for a wiring terminal, the technical solution of which is as follows:

[0022] An improved structure of a terminal block includes a fastening component 1, the upper end of which is threadedly connected to a nut 2. The upper end of the fastening component 1 has a threaded structure. A pressing block is installed below the nut 2, and a base 6 is installed below the pressing block. The fastening component 1 passes through the pressing block and connects to the base 6. A clamping block 4 moves in the middle part of the fastening component 1. A spring 5 is installed on the part of the fastening component 1 that passes through the clamping block 4 and connects to the base 6. One end of the spring 5 is located below the clamping block 4, and the other end of the spring 5 is located above the base 6. The clamping block 4 is inverted "U" shaped. Wire grooves 41 are provided on both sides of the clamping block 4. Wire holes 61 are provided on the lower part of the base 6. The bottom edge of the base 6 extends to both sides, and arc-shaped grooves 62 are provided on the two extended sides. The arc-shaped grooves 62 match the wire grooves 41 on both sides of the clamping block 4, and the center lines of the arc-shaped grooves 62 and the wire grooves 41 on both sides of the clamping block 4 coincide. A washer 3 is installed between the nut 2 and the clamping block 4, which makes the fixation between the nut 2 and the clamping block 4 more secure. It also prevents the fastening component 1 from loosening in a vibrating environment and plays a buffering role during the tightening process.

[0023] During installation, first connect the upper end of the base 6 to the lower end of the fastening component 1. Then, insert the wire into the through hole formed by the wire groove 41 and the wire hole 61. At this time, due to the elastic force of the spring 5, the clamping block 4 can be pressed upwards on the fastening component 1. To prevent the clamping block 4 from shaking on the fastening component 1, tighten the nut 2 on the fastening component 1. The spring force of the spring 5 will press the clamping block 4, fixing the clamping block 4 in the middle position of the fastening component 1. At the same time, to make the fixation between the nut 2 and the clamping block 4 more secure, a washer 3 is installed on the fastening component 1 between the nut 2 and the clamping block 4. This also prevents the fastening component 1 from loosening in a vibrating environment and provides a buffering effect during tightening. As the nut 2 is tightened, the area of ​​the through hole formed by the wire groove 41 and the wire hole becomes smaller and smaller, thereby achieving the effect of firmly clamping the wire. Similarly, during the disassembly process, when the nut 2 is loosened in the reverse direction, the spring 5 is gradually recovering as the compressive force on the spring 5 decreases, causing the clamping block 4 to move upwards. This makes the area of ​​the through hole formed by the wire groove 41 and the wire hole 61 larger and larger, allowing the wire groove 41 to move away from the wire hole 61. At this time, the wire can be quickly pulled out from the through hole formed by the wire groove 41 and the wire hole 61.

[0024] The spring 5 is directly fitted onto the fastening component 1 between the clamping block 4 and the base 6, which can prevent the spring 5 from bending and at the same time limit the clamping block 4.

[0025] This design effectively avoids the problem of wire harness damage during the tightening process, ensuring that the wires are not squeezed, deformed, or mechanically damaged during clamping, thus guaranteeing the integrity and reliability of the wires. It also effectively avoids the problem of loose wire connections, ensuring the stability and reliability of electrical connections. Even in environments with vibration or movement, it can maintain good electrical performance and eliminate safety hazards caused by loose connections. At the same time, this structure can also achieve repeated recycling and quick disassembly and installation of wires. The wire hole 61 in this structure can also be used to connect wires of different sizes and thicknesses, protecting wires of different thicknesses.

[0026] Reference Figure 2 The fastening component 1 can be a single-ended threaded rod 11. During installation, the single-ended threaded rod 11 passes through the middle of the clamping block 4 and is fixedly connected to the upper end of the base 6. The clamping block 4 moves in the middle part of the single-ended threaded rod 11. The wire is inserted into the through hole formed by the wire groove 41 and the wire hole 61. At this time, due to the elastic force of the spring 5, the clamping block 4 can be pressed upward on the single-ended threaded rod 11. In order to prevent the clamping block 4 from shaking on the single-ended threaded rod 11, the nut 2 on the single-ended threaded rod 11 is tightened. The clamping block 4 is pressed by the elastic force of the spring 5, which can fix the clamping block 4 in the middle position of the single-ended threaded rod 11. At the same time, in order to make the fixation between the nut 2 and the clamping block 4 more secure, a washer 3 is installed on the single-ended threaded rod 11 between the nut 2 and the clamping block 4. It also serves to prevent the single-ended threaded rod 11 from loosening in the vibrating environment and to buffer during the tightening process. As nut 2 is tightened, the area of ​​the through hole formed by the wire groove 41 and the through hole 61 becomes smaller and smaller, thus achieving the effect of firmly clamping the wire. Similarly, during disassembly, when nut 2 is loosened in the reverse direction, the compressive force on spring 5 decreases, and spring 5 slowly recovers, causing the clamping block 4 to gradually move upward, making the area of ​​the through hole formed by the wire groove 41 and the through hole 61 larger and larger, causing the wire groove 41 to move away from the through hole 61. At this time, the wire can be quickly pulled out from the through hole formed by the wire groove 41 and the through hole 61.

[0027] Example 1

[0028] As another embodiment of this utility model, refer to Figures 3-4The fastening component 1 can be a double-ended bolt 12. When the rotation direction of the threads at both ends of the double-ended bolt 12 is the same, the double-ended bolt 12 is first passed through the middle of the clamping block 4. The clamping block 4 moves in the middle part of the double-ended bolt 12. Then, the base 6 is installed at the lower end of the double-ended bolt 12 through the rotation direction of the threads. The wire is inserted into the through hole formed by the wire groove 41 and the wire hole 61. At this time, due to the elastic force of the spring 5, the clamping block 4 can be pressed upward on the double-ended bolt 12. In order to prevent the clamping block 4 from shaking on the double-ended bolt 12, the nut 2 is rotated and tightened along the direction of the upper thread that is the same as the thread direction of the lower end of the double-ended bolt 12. The clamping block 4 is also pressed by the elastic force of the spring 5, which can fix the clamping block 4 in the middle position of the double-ended bolt 12. As the nut 2 is tightened, the area of ​​the through hole formed by the wire groove 41 and the through hole becomes smaller and smaller, thereby achieving the effect of firmly clamping the wire. Similarly, during the disassembly process, when the nut 2 is loosened in the reverse direction, the spring 5 is gradually recovering as the compressive force on the spring 5 decreases, causing the clamping block 4 to move upwards. This makes the area of ​​the through hole formed by the wire groove 41 and the wire hole 61 larger and larger, allowing the wire groove 41 to move away from the wire hole 61. At this time, the wire can be quickly pulled out from the through hole formed by the wire groove 41 and the wire hole 61.

[0029] When the threads at the upper and lower ends of the double-ended bolt 12 rotate in opposite directions, first pass the double-ended bolt 12 through the middle of the clamping block 4. Then, install the base 6 onto the lower end of the double-ended bolt 12 according to the rotation direction of the threads. Tighten the nut 2 by rotating it along the direction of the upper thread, which is opposite to the direction of the thread at the lower end of the double-ended bolt 12. As the nut 2 is tightened, the area of ​​the through hole formed by the wire groove 41 and the through hole 61 becomes smaller and smaller, thus achieving the effect of firmly clamping the wire. Similarly, during disassembly, when the nut 2 is loosened in the opposite direction, the area of ​​the through hole formed by the wire groove 41 and the through hole 61 becomes larger and larger, causing the wire groove 41 to move away from the through hole 61. At this time, the wire can be quickly pulled out from the through hole formed by the wire groove 41 and the through hole 61.

[0030] The threads at the upper and lower ends of the double-ended bolt 12 can rotate in the same direction or in opposite directions. When the threads at the upper and lower ends rotate in the same direction, the base 6 and the nut 2 rotate clockwise or counterclockwise at both ends of the double-ended bolt 12 to clamp or loosen the wire for disassembly and installation. When the threads at the upper and lower ends rotate in opposite directions, the base 6 and the nut 2 rotate in opposite directions at both ends of the double-ended bolt 12 to clamp or loosen the wire for disassembly and installation.

[0031] Working principle: By adopting different structural designs for the fastening component 1 and using different connection methods with the base 6, the wire can be clamped or loosened for installation and removal. This effectively avoids the problem of wire harness damage during the fastening process, ensuring that the wire is not squeezed, deformed, or mechanically damaged during clamping, thus guaranteeing the integrity and reliability of the wire. It also effectively avoids the problem of loose wire connections, ensuring the stability and reliability of the electrical connection. Even in environments with vibration or movement, it can maintain good electrical performance and eliminate safety hazards caused by loose connections. At the same time, this structure can also achieve repeated recycling and quick installation and removal of wires. The wire hole 61 in this structure can also be used to connect wires of different sizes and thicknesses, protecting wires of different thicknesses.
