Description

Technical Field

[0001] This invention relates to a rivet-free interlocking wire clamping structure. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections. They bridge gaps in circuits or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. They are widely used in lighting, elevator control, instrumentation, and power supplies. The wire clamping structure, used to mate with wires in a terminal block assembly, is a key component, serving to connect and fix the wires and transmit current and signals.

[0003] In existing technologies, most wire clamping structures use rivets to fix the conductor and clamping spring together. The drawback of this structure is that it requires a specially sized rivet, which must be pre-assembled into the mounting holes for the conductor and clamping spring, and then riveted using tooling. This greatly increases the product cost and labor time, reducing market competitiveness. Summary of the Invention

[0004] The purpose of this invention is to provide a riveting-free interlocking wire clamping structure that enables quick and secure assembly, avoiding the traditional riveting process.

[0005] The above-mentioned objective of the present invention is achieved by the following solution:

[0006] A rivet-free interlocking wire clamping structure includes a clamping spring (100) and a conductor (200). The clamping spring (100) has a U-shaped long through groove (103) at its bottom and a limiting groove (101) and (102) symmetrically opened on its two sides. The clamping spring (100) has a suitable arc bending acute angle (104) and two suitable arc bending obtuse angles (105) and (106). One end of the conductor (200) is provided with two S-shaped bends (240) and (250) for connection with the fitting; the other end of the conductor (200) is provided with an upward 90° short side bend (210) at the front, and two limiting steps (203) and (204) are symmetrically opened on both sides of the root of the short side bend (210) for matching and connecting with the limiting groove (101) of the clamping spring (100); at the rear, there is an upward 90° long side bend (220) and a 90° transverse bend (230); two limiting steps (201) and (202) are symmetrically opened on both sides of the root of the long side bend (220) for matching and connecting with the limiting groove (102) of the clamping spring (100); a limiting boss (205) is opened at a suitable position of the transverse bend (230) for limiting the top of the clamping spring (100).

[0007] The assembly method for the above-mentioned rivetless interlocking wire clamp structure is as follows:

[0008] Press the top of the clamping spring (100) downwards by about 1mm. Figure 2 Push the conductor (200) from back to front along the upper surface of its bottom, as shown, so that the two limiting grooves (101) and (102) at its bottom engage with the four limiting steps (201), (202), (203), and (204) of the conductor (200). Release the clamping spring (100), and its top engages with the limiting boss (205) in the transverse bend (230) of the conductor (200), completing the assembly. The assembled state is as follows. Figure 1 As shown, the clamping spring (100) and the conductor (200) rely on their interlocking structure to achieve positioning connection of the clamping spring (100) in the up, down, left, and right directions. No additional rivet connections are required, greatly reducing product costs and enhancing market competitiveness.

[0009] The working principle of the above-mentioned rivetless interlocking wire clamping structure is as follows:

[0010] Install this rivetless interlocking wire clamping structure into the plastic housing. Use a screwdriver to press the top left side of the clamping spring (100) to the appropriate position. Insert the wire between the conductor (200) and the clamping spring (100), and then release the screwdriver to complete the connection and fixation with the wire. This wire clamping structure provides a reliable connection with the wire, and the wire holding force (pull-out force) exceeds 60N, meeting international standard requirements.

[0011] The technical effects achieved by the rivet-free interlocking wire clamping structure of the present invention are as follows:

[0012] 1. The rivet-free interlocking wire clamping structure of the present invention solves the problem in the prior art where the wire clamping structure uses rivets to fix the conductor and the clamping spring. The drawback of this structure is that it requires a specially sized rivet, which is pre-assembled into the rivet mounting hole between the conductor and the clamping spring, and then riveted using tooling. This greatly increases the product cost and labor time, and reduces market competitiveness.

[0013] 2. The rivetless interlocking wire clamping structure of the present invention makes up for the shortcomings of the prior art. By adopting a new structure, the connection and fixation through the unique interlocking assembly structure of the clamping spring and the conductor greatly reduces the cost and labor time, and improves the competitiveness in the market.
