[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] Specific implementation method 1: Figure 1-5 As shown, this embodiment describes an insulating terminal for wiring harness installation, comprising a metal tube 1, an insulating layer 2, a fixing device 3, a connecting piece 4 and a side baffle 6; two side baffles 6 are fixedly connected to the inner wall of one end of the metal tube 1, and a slideway 5 is provided between the two side baffles 6; the side of the metal tube 1 provided with the side baffle 6 is also fixedly connected to the connecting piece 4; the outer side of the metal tube 1 is provided with an insulating layer 2;

[0020] The fixing device 3 includes a slider 32 that is slidably matched with the slideway 5; one end of the slider 32 is fixedly connected to a slide plate 31, and the other end of the slider 32 is provided with a rectangular hole, in which a telescopic rod 34 that is slidably matched with the slider 31 is provided; both the free end and the fixed end of the telescopic rod 34 are provided with a mounting groove that is perpendicular to the center line of the telescopic rod 34, and a connecting block 33 is provided in the mounting groove; one end of the connecting block 33 is slidably matched with the arc-shaped sliding groove 7 on the corresponding side baffle 6, and the other end of the connecting block 33 is fixedly connected to a clamping plate 35. The fixing device 3 moves downward, driving the clamping plate 35 to move, thereby clamping the wiring harness.

[0021] The cross section of the connecting block 33 is arc-shaped. When the connecting block 33 slides in the arc-shaped slide groove 7, the connecting block 33 can change its angle along the setting direction of the arc-shaped slide groove 7, thereby driving the angle of the clamping plate 35 to change, so as to clamp the wire.

[0022] The cross section of the mounting groove is circular so that the connection block 33 is not blocked by the inner wall of the mounting groove when the angle changes.

[0023] The clamping plates 35 are configured to be sawtooth-shaped, and as the fixing device 3 moves downward, the two clamping plates 35 engage with each other.

[0024] The centers of the arcuate grooves 7 on the two side baffles 6 coincide with each other, and the center of the arcuate groove 7 is located above the center of the cross section of the metal tube 1. When the connecting block 33 moves along the arcuate groove 7, the gap between the clamping plate 35 and the metal tube 1 is gradually reduced, which is convenient for clamping the wire.

[0025] The sliding piece 31 and the connecting piece 4 are both provided with connecting holes for the bolts of the connecting terminals to pass through.

[0026] The fixing device 3 is conductive.

[0027] The thickness of the two clamping plates 35 decreases linearly from the opposite ends to the other end.

[0028] A method for using an insulating terminal for wiring harness installation, the method comprising the following steps:

[0029] Step 1: Insert the wire harness into the metal tube 1;

[0030] Step 2: Move the slide 31 and the connecting piece 4 to the location of the wiring terminal;

[0031] Step 3: Pass the bolts on the terminal block through the connecting holes on the slide 31 and the connecting piece 4, and tighten the bolts;

[0032] Step 4: Driven by the bolt, the slide 31 moves downward, driving the clamping plate 35 to clamp the wire harness.

[0033] The working principle of the present invention is as follows: when using the device, the wiring harness is inserted into the metal tube 1, and then the device is moved to the position of the wiring terminal on the electrical equipment, and the bolt passing through the upper end of the wiring terminal is passed through the connecting holes on the slide plate 31 and the connecting plate 4, and the bolt is tightened. In the process of tightening the bolt, the bolt moves downward, and the bolt drives the slide plate 31 to move downward, and then drives the telescopic rod 34 to move downward along the slideway 5 through the slider 32, and the telescopic rod 34 drives the connecting block 33 to move downward relative to the side baffle 6. Since one end of the connecting block 33 is slidably matched with the arc slide groove 7, during the downward movement, the connecting block 33 slides along the arc slide groove 7, and then drives the connecting block 33 to deviate along the setting direction angle of the arc slide groove 7, so that the connecting block 33 drives the clamping plate 35 connected thereto to move together, and then the two clamping plates 35 press the wiring harness, so that the wiring harness is close to the inner wall of the metal tube 1, and the installation is completed. The wire can be fixed by the bolt on the wiring terminal, which simplifies the installation steps and improves the installation efficiency.

[0034] At the same time, because the distance between the two clamping plates 35 decreases linearly when fixing the wire in the present invention, wires with different diameters can also be fixed, and the application range is wide.

[0035] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other forms of assembly without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations within the meaning and range of equivalents of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
