Description

Technical Field

[0001] This utility model mainly relates to the field of alloy torque universal terminal technology, specifically an alloy torque universal terminal. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections, and are classified as connectors in industry. With increasing industrial automation and more stringent and precise industrial control requirements, the use of terminal blocks is gradually rising. With the development of the electronics industry, the application range and types of terminal blocks are also expanding. Alloy torque universal terminal blocks are suitable for connecting various round, semi-circular, and sector-shaped wires and power cables in power distribution equipment. However, the existing alloy torque universal terminal block design is unreasonable. The pad can easily rotate within the terminal body's wiring hole, and the conductor lacks a limiting support device at the outer end. When the outer end of the conductor shakes, the wire harness inside the terminal can easily shake, leading to unreliable connection between the alloy torque universal terminal block and the conductor, resulting in poor wire harness contact and affecting its use.

[0023] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0024] like Figure 1-6 As shown, the universal alloy torque terminal of this utility model includes a connecting tube 1, a connecting plate 2 fixedly installed at one end of the connecting tube 1, and a mounting hole 3 opened on the top surface of the connecting plate 2, through which the connecting plate 2 can be installed on the power distribution device;

[0025] Two fastening screws 4 are threaded onto the connecting pipe 1 and are distributed on the left and right sides. The two fastening screws 4 are spaced apart front and back. A first trapezoidal groove 5 is opened on the inner wall of the bottom surface of the connecting pipe 1. A first trapezoidal slider 6 is slidably installed in the first trapezoidal groove 5. An arc-shaped pad 7 is installed on the first trapezoidal slider 6. The two fastening screws 4 can limit and fix different positions at both ends of the top side of the wire harness, ensuring the stability of the wire harness.

[0026] Limiting devices are installed on the inner walls of both sides of the connecting pipe 1, and a support and fixing component is installed at the other end of the connecting pipe 1.

[0027] Specifically, the limiting device includes a second trapezoidal slider 8, which is slidably installed in a second trapezoidal groove 9 opened on the inner wall of the connecting pipe 1. An arc-shaped plate 10 is installed on one side of the second trapezoidal slider 8, and an arc-shaped clamping plate 12 is installed on the arc-shaped plate 10 through an elastic telescopic rod 11. The second trapezoidal slider 8 is slidably installed in the second trapezoidal groove 9, and with the elastic force of the elastic telescopic rod 11, it can drive the arc-shaped clamping plate 12 to limit and fix both sides of the wire harness, thereby ensuring the stability of the wire harness in the connecting pipe 1.

[0028] Specifically, the elastic telescopic rod 11 includes a sleeve 13, within which a connecting block 15 is installed via a spring 14. A connecting rod 16 is installed on one side of the connecting block 15, and the connecting rod 16 can slide along the sleeve 13. Under the elastic force of the spring 14, the connecting block 15 and the connecting rod 16 can slide left and right along the sleeve 13, thereby enabling the arc-shaped clamp 12 to limit and fix both sides of the wire harness.

[0029] Specifically, the support and fixing assembly includes a support sleeve 17. One end of the support sleeve 17 has an internal thread, and the other end of the connecting pipe 1 is fitted with an annular plate 18, which has an external thread. The support sleeve 17 is threadedly connected to the annular plate 18. Two vertically distributed adjusting screws 19 are threadedly mounted on the support sleeve 17, and an arc-shaped support plate 20 is rotatably mounted at the bottom of each adjusting screw 19. The threaded connection between the support sleeve 17 and the annular plate 18 facilitates the installation and removal of the support sleeve 17. Rotating the adjusting screws 19 moves the arc-shaped support plate 20, thereby clamping and limiting the outer end of the wire harness, reducing the shaking of the outer end of the wire harness.

[0030] Specifically, curved rubber pads are installed on the inner surface of the curved support plate 20. The rubber pads prevent the curved support plate 20 from directly contacting the wire harness.

[0031] Specifically, a friction limiting block 21 is installed on the top surface of the arc-shaped pad 7. The friction limiting block 21 can limit the wire harness and ensure the stability of the wire harness on the arc-shaped pad 7.

[0032] Specifically, there are two mounting holes 3. The presence of two mounting holes 3 increases the stability of the connecting plate 2 during installation.

[0033] Working principle:

[0034] When using this device, first, the wire harness connection end is passed through the support sleeve 17 and inserted into the connecting tube 1. Under the elastic force of the elastic telescopic rod 11, the arc-shaped clamps 20 on both sides contact the two sides of the wire harness and limit and fix the two sides of the wire harness. Then, the fastening bolt 4 is turned by the wrench to make the fastening bolt 4 contact the wire harness. With the cooperation of the arc-shaped pad 7, the wire harness is fixed and limited, thereby fixing the wire harness connection end in the connecting tube 1. Then, the adjusting screw 19 is turned to move the adjusting bolt 19 towards the wire harness. The movement of the adjusting bolt 19 can drive the arc-shaped support plate 20 to move towards the wire harness, thereby making the arc-shaped support plate 20 contact the wire harness and clamp and limit the support of the outer end of the wire harness, thereby reducing the shaking of the outer end of the wire harness and ensuring the stability of the wire harness connection end in the connecting tube 1.

[0035] This invention utilizes two fastening screws and an arc-shaped pad to quickly fix the cable, eliminating the need for clamping tools, saving connection time, and improving connection efficiency. Simultaneously, the limiting device can limit and fix both sides of the cable harness, improving its stability within the connecting tube 1 and enhancing connection stability. Furthermore, the supporting and fixing components can support and fix the outer end of the cable harness, reducing its shaking within the connecting tube 1, further improving connection stability and ensuring effective cable connection.
