Technical Field

[0001] The utility model belongs to the technical field of shielding rings, and in particular relates to a shielding ring installation and clamping device. Background Art

[0002] The shielding ring is an indispensable part of the new energy high-voltage wire harness. The inner and outer rings of the shielding ring need to be assembled into a whole on the wire. At present, the installation of the inner and outer rings of the shielding ring is usually clamped with tweezers, and the alignment of the inner and outer rings is achieved by the operator's visual inspection. It is difficult to align accurately, the operation is inconvenient, the efficiency is low, and it is easy to cause damage to the shielding ring; some use semi-automatic or fully automatic machines for installation, but it will cause the wiring harness manufacturing cost to be too high.

[0003] A utility model patent with announcement number CN213462853U, published on June 15, 2021, discloses a "convex crimp shielding ring fixing structure" comprising a shielding inner ring, a shielding shell, a shielding outer ring, and a cable. The shielding inner ring is sleeved onto the outer sheath of the cable, the cable's shielding braid is wrapped around the outer surface of the shielding inner ring, the shielding shell is sleeved onto the cable's shielding braid, and the shielding outer ring is fixedly sleeved onto the crimping area of the shielding shell. The shielding outer ring, shielding shell, shielding inner ring, and cable are crimped and fixed by crimping tooling. This convex crimp shielding ring fixing structure cannot solve the above-mentioned technical problems. Utility Model Content

[0018] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0019] like Figure 1 and Figure 2 As shown, the shielding ring mounting clamping device includes a first handle 1 and a second handle 2, which are hinged. The ends of the first handle 1 and the second handle 2 are provided with connecting blocks 3, and the connecting blocks 3 are provided with clamping claws 4.

[0020] The shielding ring installation and clamping device is handheld and the spacing of the clamping jaws 4 is controlled by the operating handle to achieve the installation of the inner and outer rings of the shielding ring. Compared with clamping with tweezers, the operating range is easy to control, the operating action is more convenient, there is no direct contact with the shielding ring, the probability of damage to the shielding ring is low, which is conducive to reducing product losses. Compared with the use of automatic machines, the cost is lower, the manufacturing materials are simple, and it is also easy to manufacture according to the shielding ring model.

[0021] like Figure 2As shown, the clamping jaw 4 includes a clamping jaw arm 5, which is symmetrically arranged. An opening 6 is provided between one end of the clamping jaw arm 5, and the other end of the clamping jaw arm 5 is hinged in the connecting block 3. The provision of the opening 6 can facilitate the wire to directly enter the clamping jaw 4 in a radial direction, eliminating the step of axial insertion of the wire and improving the convenience of assembly. The two clamping jaw arms 5 are hingedly connected, and the size of the opening 6 is variable, so as to adapt to the clamping of wires of various sizes. In order to make the size of the opening 6 within a reasonable range, a second spring 9 is provided between the clamping jaw arms 5. For other ways to adjust the size of the opening 6: an operating lever can be provided on the connecting block 3, so that the operating lever cooperates with one or both of the clamping jaw arms 5 through a gear rack, and the size of the opening 6 between the two clamping jaw arms 5 is controlled by rotating the operating lever to facilitate the entry of the wire.

[0022] like Figure 1 As shown, the two clamping jaws 4 are arranged in parallel. The inner ring and outer ring of the shielding ring are installed axially on the conductor. When the conductor is in an aligned position after being clamped, the parallel clamping jaws 4 can ensure that the inner ring and outer ring of the shielding ring are accurately aligned, ensuring that the shielding ring is installed in place.

[0023] like Figure 1 and Figure 2 As shown, a first spring 8 is provided between the first handle 1 and the second handle 2; a second spring 9 is provided between the clamping arms 5. The first spring 8 is used to reset the handles and simultaneously maintain a parallel position between the two clamping jaws 4. To prevent the openings 6 of the two clamping jaws 5 from being too large or too small, a second spring 9 is provided to maintain a reasonable distance between the openings 6 under normal conditions. When clamping a wire, the second spring 9 stretches to secure the wire securely, preventing it from slipping out of the opening 6.

[0024] like Figure 2 As shown, the clamping arm 5 has an arc-shaped structure, and the end of the clamping arm 5 is provided with a guide surface 7. To facilitate the entry of the wire through the opening 6, the guide surface 7 is provided so that the spacing of the opening 6 gradually decreases from the outside to the inside, and it smoothly transitions with the clamping arm 5, adapting to the cylindrical shape of the wire, so that the process of guiding the wire into the clamping jaw 4 is smooth, and no large movement will cause damage to the shielding ring.

[0025] like Figure 2 As shown, a spacer 10 is provided on one side of the second spring 9. To prevent the second spring 9 from contacting and damaging the inner and outer rings of the shielding ring, a spacer 10 is provided between the mounting area of the inner and outer rings of the shielding ring and the second spring 9. The spacer 10 is made of an elastic belt and has a certain elastic effect to adapt to the opening and closing action of the clamping arm 5.

[0026] like Figure 2 As shown, the handle end is provided with a rounded corner 11. The rounded corner 11 makes the handle end transition smoothly to prevent injury to the operator's hand.

[0027] The operating method of the shielding ring installation and clamping device is as follows: install the inner and outer rings of the shielding ring on the wire, control the distance between the two to a certain extent to avoid direct contact, the operator holds the operating handle to expand the distance between the two jaws 4, and inserts the two ends of the wire into the jaws 4 from the opening 6 to ensure that the wire is stably clamped and in a collimated posture. The operator gradually stops applying force to the handle, and the two handles are reset under the action of the first spring 8, thereby driving the distance between the two jaws 4 to gradually decrease until it returns to a parallel state. In this process, the inner and outer rings of the shielding ring are pushed by the two jaws 4 respectively, gradually approach and complete the assembly on the wire, and then the wire can be removed from the opening 6, and the jaws 4 are reset under the action of the second spring 9, and then the subsequent installation process can be carried out.

[0028] The shielding ring installation clamping device stably clamps the wire by setting the clamping jaws 4 to keep the guide in alignment. The installation of the inner and outer rings of the shielding ring is achieved by adjusting the distance between a pair of clamping jaws 4. Compared with traditional technologies, the convenience of operation is improved, the probability of damage to the shielding ring is reduced, the work efficiency is effectively improved, and the manufacturing cost of the wire harness is reduced. The shielding ring installation clamping device also has the advantages of simple structure and easy manufacturing.
