[0002] A wiring harness is a group of metal wires and cables tied together to carry signals and power connections between devices.

[0003] After the wire harness is produced and formed, it needs to be integrated and bundled. In the existing technology, most of the integration and bundling are done manually. During the integration and bundling process, it is necessary to manually clamp the wire harness into a whole, which is time-consuming, labor-intensive and has low production efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is: the utility model provides a novel wire clamp for a wire harness to solve the problem that manual clamping of the wire harness is time-consuming and labor-intensive and has low production efficiency.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a new type of wire clamp for a wire harness, comprising a frame, a first clamp installed on the frame, a second clamp movably installed on the frame, and a third clamp movably installed on the frame, the third clamp is located between the first clamp and the second clamp, the third clamp is provided with a first clamping surface on both sides in the longitudinal direction, the first clamp and the second clamp are provided with a second clamping surface facing the side of the third clamp, and the first clamping surface and the second clamping surface form a clamping space for clamping the wire harness;

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0024] The length direction of the wire clamp is the longitudinal direction.

[0025] Example

[0026] like Figure 1-5 As shown, a new type of wire clamp for a wire harness comprises a frame 1, a first clamp 4 installed on the frame 1, a second clamp 3 movably installed on the frame 1, and a third clamp 2 movably installed on the frame 1, wherein the third clamp 2 is located between the first clamp 4 and the second clamp 3, and first clamping surfaces are arranged on both longitudinal sides of the third clamp 2, and second clamping surfaces are arranged on the sides of the first clamp 4 and the second clamp 3 facing the third clamp 2, and the first clamping surface and the second clamping surface form a clamping space for clamping the wire harness; wherein, anti-slip protrusions 11 are arranged on both longitudinal sides of the third clamp 2, and anti-slip grooves 12 adapted to the anti-slip protrusions 11 are arranged on the sides of the first clamp 4 and the second clamp 3 facing the third clamp 2.

[0027] Specifically, the second clamps 3 move toward the direction of the first clamps 4, and during the movement, the third clamps 2 can be driven to move toward the direction of the first clamps 4, so that the first clamping surface and the second clamping surface between the second clamps 3 and the third clamps 2 and the first clamping surface and the second clamping surface between the third clamps 2 and the first clamps 4 gradually enclose a clamping space to fix the internal wiring harness. After the multiple wiring harnesses are fixed, they can be integrated and bundled. Since the wiring harness is clamped by the first clamp 4, the second clamp 3 and the third clamp 2, no manual clamping is required, which saves time and effort and has high production efficiency. When the second clamps 3 and the third clamps 2 move toward the direction of the first clamp 4, in order to prevent the wiring harness from escaping from the clamping space, an anti-slip protrusion 11 is provided to limit the wiring harness to prevent the wiring harness from escaping, and an anti-slip groove 12 adapted to the anti-slip protrusion 11 is provided, so that in the process of the first clamping surface and the second clamping surface enclosing the clamping space, the anti-slip protrusion 11 can be inserted into the anti-slip groove 12 to avoid interference with the formation of the clamping space.

[0028] Furthermore, the frame 1 is provided with a longitudinal slide rail 9, and the second clamp 3 and the third clamp 2 are provided with a slide groove 10 adapted to the longitudinal slide rail 9, and the movement direction of the second clamp 3 and the third clamp 2 is limited by the cooperation between the rail 9 and the slide groove 10;

[0029] A screw rod 5 is rotatably arranged in the frame 1, and the second clamp 3 is screwed to the screw rod 5. The second clamp 3 is restricted by the slide rail 9 and cannot rotate. In the process of rotating the screw rod 5, since the screw rod 5 is screwed to the second clamp 3, the second clamp 3 moves back and forth longitudinally along the slide groove 10 to form or open the clamping space. The third clamp 2 moves under the push of the second clamp 3. Preferably, the screw rod 5 is connected to a motor, and the motor drives the screw rod 5 to rotate to complete the clamping.

[0030] Furthermore, the third clamp 2 is provided with a clamp, and a long nut 13 is provided on the inner side of the clamp. The long nut 13 is screwed to the screw rod 5. In order to increase production efficiency, the third clamp 2 is fixed to the long nut 13 through the clamp. In the process of forming the clamping space, the third clamp 2 and the second clamp 3 move toward the first clamp 4 at the same time, and two clamping spaces are generated quickly. After the clamping space between the third clamp 2 and the first clamp 4 is formed, the clamp can be loosened. In addition, by providing the clamp and the long nut 13, only the clamping space between the third clamp 2 and the first clamp 4 can be used, so that the wire clamp can meet more work requirements. The longitudinal length of the long nut 13 is greater than the longitudinal length of the clamp. By fixing the clamp to different positions on the long nut 13, the position of the third clamp 2 can be fine-tuned to adapt to different working conditions.

[0031] Further, the clamp includes a C-shaped ring 16, a first fixed end 15 provided at one open end of the C-shaped ring 16, and a second fixed end 14 provided at the other open end of the C-shaped ring 16. The first fixed end 15 is threaded with a locking screw 6, and the locking screw 6 is rotatably connected to the second fixed end 14. The outer side of the C-shaped ring 16 is provided with a connecting piece 17, and the connecting piece 17 is connected to the third clamp 2. The C-shaped ring 16 is connected to the third clamp 2 through the connecting piece 17 and cannot rotate. At this time, the locking screw 6 is screwed, so that the first fixed end 15 and the second fixed end 14 of the C-shaped ring 16 move away from or close to each other, thereby achieving the tightening and loosening of the clamp.

[0032] Furthermore, the inner side of the C-shaped ring 16 is provided with anti-slip grooves; the anti-slip grooves are used to increase the clamping force during clamping. The end of the screw 5 is provided with a through hole 18; the through hole 18 is connected to an external screwing part, and the difficulty of screwing is reduced through a lever.

[0033] And / or, a locking nut 7 is threadedly connected to the outer side of the screw rod 5. The locking nut 7 locks the screw rod 5 through the friction between the locking nut 7 and the frame body 1 to prevent the screw rod 5 from loosening.

[0034] Furthermore, the first clamping surface and the second clamping surface are provided with anti-skid teeth 8, and the cross-sectional shape of the anti-skid teeth 8 is one of trapezoidal, triangular, and arc-shaped. The first clamping surface and the second clamping surface increase the contact area with the wire harness through the anti-skid teeth 8, so as to facilitate tightening the wire harness.

[0035] The above-mentioned technical features can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
