Description

Technical Field

[0001] The utility model belongs to the technical field of wire harness positioning, and particularly relates to a wire harness positioning tooling. Background Technique

[0002] A wire harness is an integrated cable device formed by combining wires or cables together through processes such as binding, coating, sleeving, and shaping. It is widely used in fields such as automobiles, airplanes, household appliances, electronic devices, and industrial machinery to achieve the transmission of electrical signals or power.

[0003] When the front end of the wire harness is inserted into the cavity of the cylinder-piercing part, the tail is exposed outside the cavity. After pressing against the cavity, screws are screwed on both ends for fixation. Therefore, there are direction requirements. And there are dimensional requirements for the cylinder-piercing part from the two-end connectors on the wire harness. So the cylinder-piercing part needs to be moved and positioned. The cylinder-piercing part plays a sealing role. So the aperture of the wire-piercing hole is thinner than the wire diameter of the wire, resulting in difficulty in moving the cylinder-piercing part. It is necessary to pull the wires one by one, and the correct size cannot be completed at one time. It is necessary to repeat the measurement operation. Purely relying on manual visual inspection cannot ensure the correct size of the cylinder-piercing part from the two-end connectors, nor can it ensure that the front end of the cylinder-piercing part faces the small connector and the tail end faces the large connector. Therefore, in view of the above problems, it is of great significance to provide a wire harness positioning tooling according to the utility model. Summary of the Utility Model

[0004] The utility model provides a wire harness positioning tooling. This tooling can ensure the correctness of the insertion direction of the cylinder-piercing part. If the direction of the cylinder-piercing part is incorrect, it cannot be inserted into the second profiling groove. Since the distances between the first stop block, the second stop block, and the third stop block are fixed according to the customer requirements, it can ensure the consistency and accuracy of the total length of each wire harness part and the distances from the two-end connectors to the cylinder-piercing part. And the sizes of the wires exposed outside the first stop block, the second stop block, and the third stop block are also fixed, which can ensure the consistency and accuracy of the winding size; the first stop block, the second stop block, and the third stop block are all supported by support frames. The wire harness part is placed in the air on the tooling, making it more convenient and fast for employees to wind the tape; it occupies a small space, is convenient for employees to carry to each process, reduces the cost of purchasing special equipment for the company, improves the reliability of the product, greatly reduces the difficulty of employees' operation, and greatly improves the work efficiency. In summary, the problems in the background technique are solved.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] A wiring harness positioning tool of the present utility model includes a base and a wiring harness component. Above the base, a first stopper, a second stopper, and a third stopper are respectively arranged.

First covers and second covers are respectively installed on the tops of the first stopper and the third stopper, and first profiling grooves, second profiling grooves, and third profiling grooves are respectively formed on the top surfaces of the first stopper, the second stopper, and the third stopper. The wiring harness component includes a large connector, a small connector, a cylinder-piercing component, and an electric wire. The electric wire passes through the cylinder-piercing component, and its two ends are respectively connected to the large connector and the small connector, and first tape and second tape are respectively wound around the electric wire.

[0007] Further, the first profiling groove, the second profiling groove, and the third profiling groove respectively match the sizes of the large connector, the cylinder-piercing component, and the small connector.

[0008] Further, the number of the electric wires is 10, and the wire diameter is larger than the aperture of the cylinder-piercing component.

[0009] Further, the two ends of the electric wire are crimped with terminals and respectively inserted into the holes of the large connector and the small connector, and are connected to the large connector and the small connector through terminal locking hooks.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0025] In the description of the present utility model, it should be understood that the terms "relative", "one end", "inside", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc. indicating orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0026] Please refer to Figures 1-5 As shown, a wire harness positioning tooling of the present utility model includes a base 1 and a wire harness component. Above the base 1, a first stop block 2, a second stop block 3 and a third stop block 4 are respectively arranged. The bottoms of the first stop block 2, the second stop block 3 and the third stop block 4 are fixedly connected with support frames 5, and the bottoms of the support frames 5 are fixedly connected to the top of the base 1. The tops of the first stop block 2 and the third stop block 4 are respectively provided with a first cover plate 6 and a second cover plate 7. The first cover plate 6 and the second cover plate 7 are rotatably connected to the first stop block 2 and the third stop block 4, and the first cover plate 6 and the second cover plate 7 can respectively rotate around the tops of the first stop block 2 and the third stop block 4. First profiling grooves 8, second profiling grooves 9 and third profiling grooves 10 are respectively formed on the top surfaces of the first stop block 2, the second stop block 3 and the third stop block 4. The wire harness component includes a large connector 11, a small connector 12, a cylinder-piercing part 13 and a wire 14. The large connector 11 selects a 6189-7602 type sheath, the small connector 12 selects a 5051511200 type sheath. The wire 14 passes through the cylinder-piercing part 13, and its two ends are respectively connected to the large connector 11 and the small connector 12, and first tapes 15 and second tapes 16 are respectively wound on the wire 14.

[0027] Among them, the first profiling groove 8, the second profiling groove 9 and the third profiling groove 10 respectively match the sizes of the large connector 11, the cylinder-piercing part 13 and the small connector 12. The large connector 11, the cylinder-piercing part 13 and the small connector 12 can respectively be aligned and fitted in the first profiling groove 8, the second profiling groove 9 and the third profiling groove 10. By rotating the first cover plate 6 and the second cover plate 7, they can be respectively buckled on the large connector 11 and the small connector 12 to fix the large connector 11 and the small connector 12. When the direction of the cylinder-piercing part 13 is incorrect, the cylinder-piercing part 13 will not be able to be inserted into the second profiling groove 9.

[0028] Among them, the number of wires 14 is 10, and its wire diameter is larger than the aperture of the cylinder-piercing part 13, which can ensure the sealing performance of the cylinder-piercing part 13.

[0029] Among them, both ends of the wire 14 are crimped to terminals and respectively inserted into the holes of the large connector 11 and the small connector 12, and are connected to the large connector 11 and the small connector 12 through terminal locking hooks. The crimping in the wire harness is to apply pressure to a metal object by a machine, causing the metal object to deform and wrap around other objects to achieve the function of mutual connection. The terminal locking hook needs to hook the sheath cavity to ensure that the wire does not fall off.

[0030] Among them, the bottom surface of the base 1 is engraved with herringbone anti-slip patterns. When the base 1 is placed on a smooth contact surface, the anti-slip patterns can be used to increase the friction between the base 1 and the contact surface to play an anti-slip role, thereby effectively preventing the tooling from slipping and displacing during use and affecting the positioning of the wire harness.

[0031] The circuits, electronic components and chip modules involved in the present utility model are all prior arts and can be fully realized by those skilled in the art without further elaboration. The content protected by the present utility model also does not involve improvements to software and methods.

[0032] The standard parts used in the application documents can be purchased from the market. All the components in the application documents can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, welding, etc. that are mature in the prior art. The machines, parts and equipment all adopt conventional models in the prior art. The electrical components mentioned in this article are all electrically connected to the external main controller and 220V mains power, and the main controller can be a conventional known device such as an LED lamp body to play a control role.

[0033] The working principle of the present utility model is:

[0034] When the utility model is in use, the wire 14 in the wiring harness is passed through the cylinder member 13, and then the two ends of the wire 14 are crimped with the terminals and respectively inserted into the holes of the large connector 11 and the small connector 12, and connected with the large connector 11 and the small connector 12 through the terminal locking hook. The crimping in the wiring harness is to apply pressure to the metal object by a machine, so that the metal object is deformed and then wraps other objects to achieve the effect of mutual connection. The terminal locking hook needs to hook the sheath cavity to ensure that the wire does not fall off. Then the large connector 11 is inserted into the first profiling groove 8 at the top of the first stopper 2, and the first cover plate 6 is buckled, and then the cylinder member 13 is inserted into the second profiling groove 9 at the top of the second stopper 3 to ensure that the direction of the cylinder member 13 is correct. If the direction is wrong, the cylinder member 13 will not be able to be inserted into the second profiling groove 9. Subsequent employees only need to straighten the wire 14 from the right side, and there is no need to repeatedly pull and measure, thereby greatly improving efficiency. After the wire 14 is straightened, the small connector 12 is inserted into the top of the third stopper 4 The third profiling groove 10 of the part is inserted into the third profiling groove 10, and the second cover plate 7 is buckled. If the small connector 12 cannot reach the third profiling groove 10, that is, the size of the wiring harness is short and unqualified. If the small connector 12 exceeds the third profiling groove 10 after being straightened, it can also be inserted into the third profiling groove 10. The subsequent process of wrapping the second adhesive tape 16 can be adjusted. After that, the large connector 11, the small connector 12, and the cylinder member 13 are respectively fixed on the first stopper 2, the second stopper 3 and the third stopper 4, and the first cover plate 6 and the second cover plate 7 are buckled, The employee starts to wind the first tape 15 and the second tape 16 from the position close to the first stopper 2 and the third stopper 4, and winds them until they are close to the second stopper 3, that is, the wires 14 exposed outside the first stopper 2, the second stopper 3 and the third stopper 4 are fully wound with the first tape 15 and the second tape 16. After winding the first tape 15 and the second tape 16, the first cover plate 6 and the second cover plate 7 are opened, and the wiring harness component can be taken out. This tooling can ensure that the size of each wiring harness component is correct and can ensure the consistency of the wiring harness components.
