Description

Technical Field

[0001] The utility model relates to the technical field of wiring terminals, in particular to a copper wiring terminal. Background Art

[0002] The terminal block is an accessory product used to achieve electrical connection. The terminal block is used to facilitate the connection of wires.

[0003] For example, the copper-pressed terminal block with authorization announcement number "CN205609761U" has a welded gap in the terminal tube, which allows the tube to maintain strong structural strength. Therefore, the side walls of the terminal tube will not be staggered during wiring, preventing the side edges of the plate from protruding from the outer wall of the terminal tube and causing scratches to workers. Furthermore, when the terminal tube is radially deformed under pressure, the contact area between the inner wall of the terminal tube and the cable will not be affected, ensuring a secure connection. However, when installing the terminal block, the wires often become twisted because the terminal block and the wires cannot rotate, which is very unsightly and poses a safety hazard. When connecting wires, the wire stripping length is often too long, resulting in part of the conductor not being covered by the terminal tube, posing a safety hazard. Utility Model Content

The second wiring tube 6 is crimped by a special crimping pliers, and the excessively long portion of the stripped wire can be crimped and covered, thereby ensuring the safe and reliable connection between the copper terminal and the wire and avoiding safety hazards. A second through-hole 7 is provided on the upper surface of the second wiring tube 6, the lower end of the first wiring tube 5 passes through the second through-hole 7, and a wire is provided inside the second wiring tube 6. The wire includes an insulating layer 8 and a conductor 9, and the upper end of the conductor 9 extends into the interior of the first wiring tube 5.

[0020] A first latching edge 10 is integrally formed at the lower end of the first hollow column 2. The outer diameter of the lower end of the first latching edge 10 is larger than the diameter of the inner wall of the first through hole 4. The provision of the first latching edge 10 prevents the first hollow column 2 from separating from the second hollow column 3. A second latching edge 11 is integrally formed at the lower end of the first wiring tube 5. The outer diameter of the lower end of the second latching edge 11 is larger than the diameter of the inner wall of the second through hole 7.

[0021] The inner wall of the second wiring tube 6 is provided with a plurality of anti-skid protrusions 12. The plurality of anti-skid protrusions 12 make the connection between the second wiring tube 6 and the insulating layer 8 more secure.

[0022] First extrusion holes 13 are provided on the lower portion of the first hollow column 2 and on both sides of the first clamping edge 10. The two first extrusion holes 13 facilitate crimping of the first hollow column 2 and the first clamping edge 10. Second extrusion holes 14 are provided on both sides of the second hollow column 3. Third extrusion holes 15 are provided on the lower portion of the first wiring barrel 5 and on both sides of the second clamping edge 11. The two third extrusion holes 15 facilitate crimping of the first wiring barrel 5 and the second clamping edge 11.

[0023] The second wiring tube 6 is provided with fourth extrusion holes 16 on both sides thereof. The two fourth extrusion holes 16 are provided to facilitate crimping of the second wiring tube 6.

[0024] A plurality of first reinforcing ribs 17 are annularly arranged on the surface of the second hollow column 3, a plurality of second reinforcing ribs 18 are annularly arranged on the surface of the first wiring tube 5, and a plurality of third reinforcing ribs 19 are annularly arranged on the surface of the second wiring tube 6. The first reinforcing ribs 17, second reinforcing ribs 18, and third reinforcing ribs 19 respectively reinforce the second hollow column 3, first wiring tube 5, and second wiring tube 6, ensuring that they are not damaged when crimped with specialized crimping pliers.

[0025] Working principle: first, strip off the insulation layer 8 of the wire to an appropriate size to expose the conductor 9, then extend the exposed conductor 9 into the first wiring tube 5, crimp it with a special crimping pliers, and then crimp the second wiring tube 6. The excessively long conductor 9 can be crimped and covered to ensure that the wire is reliably connected to the copper terminal; the set connecting terminal 1 is connected by rotating through the first hollow column 2 and the second hollow column 3. When the connecting terminal 1 is rotated to the appropriate position, the first hollow column 2 and the second hollow column 3 are crimped by a special crimping pliers to fix the first hollow column 2 and the second hollow column 3 firmly. Since the wire installed on the first wiring tube 5 and the connecting terminal 1 rotate with each other, the wire will not be twisted when the connecting terminal 1 is fixed. It is very beautiful and there is no safety hazard.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
