Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of harness processing, in particular to a harness pipe penetrating guide jig. BACKGROUND

[0002] The harness is the main body in the automobile circuit, which is formed by connecting terminals and cable crimping, and usually multiple harnesses are bundled to form the components of the circuit. In order to make the harness on the automobile more concise and provide protection for the harness, the multiple harnesses are usually penetrated through the pipe. The corrugated pipe can be arbitrarily bent, has good ductility and elasticity, and is usually used as a pipe for penetrating the harness. However, because the inner wall of the corrugated pipe is a corrugated structure, and the harness itself is also easy to bend, the harness still bends during the pipe penetrating process and cannot be directly penetrated through the corrugated pipe. The corrugated inner wall of the corrugated pipe also becomes an obstacle for the movement of the connecting terminal, resulting in difficulty in simultaneously penetrating multiple harnesses through the pipe, thereby reducing the pipe penetrating operation efficiency. CONTENT OF THE UTILITY MODEL

[0003] Therefore, it is necessary to provide a harness pipe penetrating guide jig, and the specific technical scheme is as follows.

[0011] Further, the clamping body is made of rubber material.

[0012] Further, the convex ring is aligned with the concave ring, so that the central surface of the convex ring is coplanar with the central surface of the concave ring.

[0013] Further, the length of the inner tube is greater than the length of the outer tube, so that one end of the inner tube abuts against the guide head and the other end extends to the outside of the outer tube.

[0034] Embodiment

[0035] The present embodiment provides a harness 5 pipe penetrating guide jig, referring to Figure 1 and Figure 2 , comprising an inner tube 1, an outer tube 2 and a guide head 3. Referring to Figure 3 , a convex ring 11 is arranged on the inner wall of the inner tube 1, and the inner diameter of the convex ring 11 is smaller than the inner diameter of the inner tube 1. A lock type structure is formed at the position of the convex ring 11. The connecting terminal 51 of the harness 5 is generally a plastic part, which is relatively hard and will not deform, and the size of the connecting terminal 51 is much larger than that of the harness 5. When multiple harnesses 5 are placed in the inner tube 1, the convex ring 11 limits the connecting terminal 51, so as to avoid the separation of the harness 5 from the inner tube 1 as much as possible during the pipe penetrating process.

[0036] Referring to Figure 1 , the outer tube 2 is rotatably sleeved on the outer tube 1. Referring to Figure 2 , a first opening 12 extending along the axis direction is arranged on the side wall of the inner tube 1, and a second opening 21 extending along the axis direction is arranged on the side wall of the outer tube 2. By relatively rotating the inner tube 1 and the outer tube 2, the first opening 12 and the second opening 21 can be aligned or staggered. When the harness 5 is taken out or placed in the guide jig, the inner tube 1 and the outer tube 2 are rotated to align the first opening 12 and the second opening 21, so that the guide jig forms an open type, and the harness 5 can be quickly placed in the inner tube 1 through the first opening 12 and the second opening 21. Before the pipe penetrating process, the inner tube 1 and the outer tube 2 are relatively rotated to stagger the first opening 12 and the second opening 21, so that the guide jig forms a closed type, thereby avoiding the separation of the harness 5 from the guide jig during the pipe penetrating process.

[0037] Specifically, with continued reference to Figure 1 As shown in the figure, the guide head 3 includes a first end and a second end, and the outer diameter of the guide head 3 gradually decreases from the first end to the second end. The second end of the guide head 3 is connected with the end of the outer tube 2. When threading the tube, the guide tool is inserted into the corrugated tube under the guidance of the guide head 3.

[0038] The guide tool for threading the wire harness 5 provided by the embodiment can switch the guide tool into an open type and a closed type by switching the relative positions of the first opening 12 and the second opening 21 by relatively rotating the inner tube 1 and the outer tube 2, can take and place the wire harness 5 in the open type, and can perform the threading operation in the closed type. By threading the guide tool through the corrugated tube, multiple wire harnesses 5 can be guided to thread the tube at the same time, and the guide tool can pass through the corrugated tube more smoothly, the threading operation is more convenient and labor-saving, and the efficiency of the threading operation is greatly improved.

[0039] Specifically, with reference to Figure 3 As shown in the figure, the outer wall of the inner tube 1 is provided with a concave ring 13, the inner wall of the outer tube 2 is formed with an arc-shaped protrusion 43, and the arc-shaped protrusion 43 is rotatably clamped in the concave ring 13. By clamping the arc-shaped protrusion 43 and the concave ring 13, the inner tube 1 and the outer tube 2 can be limited in the axial direction, so as to avoid separation of the inner tube 1 and the outer tube 2 during the threading process.

[0040] Specifically, the outer tube 2 is provided with a clamping groove 22, the clamping groove 22 is provided with a plug-in block 4, and the arc-shaped protrusion 43 is located on one side surface of the plug-in block 4. When assembling the inner tube 1 and the outer tube 2, the inner tube 1 is first threaded into the outer tube 2 from the end of the outer tube 2, so that the clamping groove 22 is aligned with the concave ring 13; then the plug-in block 4 is inserted into the clamping groove 22, so that the arc-shaped protrusion 43 enters the concave ring 13 to limit the inner tube 1 and the outer tube 2. The above structure facilitates the assembly of the inner tube 1 and the outer tube 2, reduces the production difficulty of the guide tool, thereby reducing the cost, and is simple and practical.

[0041] Specifically, the clamping groove 22 comprises a sunk head 23 and a clamping part 24 connected with the sunk head 23; the insertion block 4 comprises an end head 41 and a clamping body 42 connected with the end head 41; the end head 41 is located in the sunk head 23, and the clamping body 42 is clamped in the clamping part 24; the arc-shaped protrusion 43 is located on the side of the clamping body 42 away from the end head 41. The cross-sectional area of the sunk head 23 is larger than that of the clamping part 24, and the cross-sectional area of the end head 41 is larger than that of the clamping body 42, so as to limit the insertion depth of the arc-shaped protrusion 43 and avoid the exposure of the end head 41 to the outer wall of the outer tube 2 to affect the pipe penetrating. By clamping the clamping body 42 in the clamping part 24, the relative fixation between the insertion block 4 and the outer tube 2 is realized. In this embodiment, the clamping body 42 is made of rubber material, so as to realize the clamping of the clamping body 42 in the clamping part 24. Correspondingly, the entire insertion block 4 can also be made of rubber material.

[0042] Specifically, the convex ring 11 is aligned with the concave ring 13, so that the central surface of the convex ring 11 is coplanar with the central surface of the concave ring 13. In this embodiment, the inner tube 1 and the outer tube 2 can be metal pipes, so that the concave ring 13, the convex ring 11, the clamping groove 22 and other structures are easy to process.

[0043] Specifically, the length of the inner tube 1 is greater than that of the outer tube 2, so that one end of the inner tube 1 abuts against the guide head 3, and the other end extends to the outside of the outer tube 2. During the pipe penetrating process, the operator can hold the inner tube 1 and the outer tube 2 with hands at the same time, so as to reduce or avoid the relative rotation of the inner tube 1 and the outer tube 2, thereby avoiding the alignment of the first opening 12 and the second opening 21.

[0044] Specifically, the surface of the outer tube 2 is smooth, which facilitates the direct penetration of the guide tool through the corrugated pipe, and saves time and labor.

[0045] Specifically, the first opening 12 penetrates the inner tube 1 along the axial direction; and the second opening 21 penetrates the outer tube 2 along the axial direction.

[0046] Pipe penetrating process:

[0047] The inner tube 1 and the outer tube 2 are rotated to align the first opening 12 with the second opening 21, the plurality of wire harnesses 5 are placed in the inner tube 1 through the first opening 12 and the second opening 21, and the connection terminals 51 are located in the area where the convex ring 11 and the guide head 3 are located, and the connection terminals 51 are simply limited by the convex ring 11 when the plurality of wire harnesses 5 are placed in the inner tube 1; then the inner tube 1 and the outer tube 2 are relatively rotated to misalign the first opening 12 with the second opening 21, the through slot is rotated by 180° to make the first opening 12 as far away from the second opening 21 as possible; the guide tool is inserted into the corrugated tube by using the guide head 3, and the guide tool is pulled out from the other end; finally, the inner tube 1 and the outer tube 2 are relatively rotated again to align the first opening 12 with the second opening 21, so that the wire harnesses 5 are taken out from the guide tool.

[0048] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.

[0049] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
