[0011] Optionally, the surface of the protrusion is provided with a drag-reducing layer to reduce frictional resistance.

[0012] Optionally, the drag-reducing layer is constructed as a chromium layer.

[0013] Optionally, the wire harness clip separation tool further includes an elastic element, the two ends of which are respectively connected to the first handle portion and the second handle portion, and the elastic element is configured to compress when the first handle portion and the second handle portion are brought close to each other.

[0014] Optionally, the elastic element is constructed as a spring.

[0015] Optionally, the wire harness clip separation tool further includes a rotating shaft, the first connecting part is provided with a first through hole, the second connecting part is provided with a second through hole corresponding to the first through hole, and the rotating shaft is rotatably inserted into the first through hole and the second through hole.

[0016] Optionally, both the first handle portion and the second handle portion are provided with an anti-slip layer.

[0017] According to the above technical solution, the wire harness clip separation tool includes a first clamp arm and a second clamp arm. The first clamp arm includes a first handle portion, a first clamp head, and a first connecting portion disposed between the first handle portion and the first clamp head.

Detailed Implementation

[0026] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0027] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to the inner and outer contours of the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0028] The inventors discovered that the engine's high-pressure fuel rail harness 30 is mounted on a snap-fit ​​mounting bracket 20 via a snap-fit ​​mechanism. The snap-fit ​​mounting bracket 20 is mounted on the engine's bracket, allowing the high-pressure fuel rail harness 30 to be removed when disassembling the high-pressure fuel rail. Figures 2 to 4 As shown, the high-pressure oil rail harness 30 includes a harness body 31 (wherein, attached...) Figures 2 to 4The diagram shows a portion of the wire harness body 31 (specifically, the connector portion) and a wire harness clip 32 mounted on the wire harness body 31. The clip 32 includes a slot 322 and a limiting portion 321. The clip mounting bracket 20 includes a first mounting portion 21, a second mounting portion 23, and a third connecting portion 22 connecting the first mounting portion 21 and the second mounting portion 23. The first mounting portion 21, the third connecting portion 22, and the second mounting portion 23 are C-shaped. The first mounting part 21, the second mounting part 23, and the third connecting part 22 can all be constructed as plates. The second mounting part 23 is provided with a limiting hole 231. The first mounting part 21 can be mounted on the engine bracket. The second mounting part 23 passes through the slot 322 of the wire harness clip 32. The limiting part 321 of the wire harness clip 32 is inserted into the limiting hole 231, so that the wire harness clip 32 is mounted on the second mounting part 23, that is, the high-pressure oil rail wire harness 30 can be mounted on the second mounting part 23. When disassembling the high-pressure oil rail wire harness 30, the limiting part 321 needs to be pulled out from the limiting hole 231, and then the wire harness clip 32 is slid to make the second mounting part 23 disengage from the slot 322, thereby removing the high-pressure oil rail wire harness 30 from the clip mounting bracket 20. When the limiting part 321 of the wire harness clip 32 is pulled out from the limiting hole 231 of the second mounting part 23, the traditional disassembly method is to directly use your hands or use a screwdriver or needle-nose pliers to pry it, which is not easy to operate, has low operating efficiency, and is also easy to damage the wire harness clip 32.

[0029] In order to at least partially solve the above-mentioned technical problems, such as Figures 1 to 2As shown, this disclosure provides a wire harness clip separation tool 10, including a first clamp arm 11 and a second clamp arm 12. The first clamp arm 11 includes a first handle portion 111, a first clamp head 113, and a first connecting portion 112 disposed between the first handle portion 111 and the first clamp head 113. The first clamp head 113 is further provided with a positioning portion 114 for positioning and engaging with a clip mounting bracket 20. The second clamp arm 12 includes a second handle portion 121, a second clamp head 123, and a second connecting portion 123 disposed between the second handle portion 121 and the second clamp head 123. 2, wherein the first connecting part 112 is hinged to the second connecting part 122 so that the first clamp arm 11 and the second clamp arm 12 can rotate relative to each other. When the first handle part 111 and the second handle part 121 approach each other, the first clamp head 113 and the second clamp head 123 can move away from each other through the relative rotation between the first clamp arm 11 and the second clamp arm 12. When the first handle part 111 and the second handle part 121 move away from each other, the first clamp head 113 and the second clamp head 123 can approach each other through the relative rotation between the first clamp arm 11 and the second clamp arm 12. When the wire harness clip 32 is separated from the clip mounting bracket 20 using the wire harness clip separation tool 10, the positioning part 114 provided on the first clamp head 113 can be positioned and engaged with the clip mounting bracket 20, which can be used to position the wire harness clip separation tool 10. Force can be applied to the first handle part 111 and the second handle part 121 to separate the first clamp head 113 and the second clamp head 123 from each other. The protrusion 124 provided on the side of the second clamp head 123 opposite to the first clamp head 113 can be inserted into the limiting hole 231 of the clip mounting bracket 20, and the limiting part 321 inserted into the limiting hole 231 of the clip mounting bracket 20 is pushed out, so as to facilitate the separation between the wire harness clip 32 and the clip mounting bracket 20. By using the wire harness clip separation tool 10, the problem of damage caused when disassembling the wire harness clip 32 can be reduced, and the disassembly efficiency can be improved.

[0030] In the above embodiments, by using the wire harness clip separation tool 10 to disassemble the wire harness clip 32, the direct contact between the clip mounting bracket 20 and the wire harness clip 32 by hand is avoided, which can improve the safety of operation to a certain extent.

[0031] It should be understood that in the above-described embodiments, the positioning part 114 provided on the first clamp head 113 mentioned above can be positioned and engaged with the snap-fit ​​mounting bracket 20, and can be used to position the wire harness snap-fit ​​separating tool 10. This does not mean that the wire harness snap-fit ​​separating tool 10 is restricted and cannot move after the positioning part 114 of the wire harness snap-fit ​​separating tool 10 is positioned and engaged with the snap-fit ​​mounting bracket 20. Rather, through the positioning engagement between the positioning part 114 and the snap-fit ​​mounting bracket 20, the movement of the wire harness snap-fit ​​separating tool 10 can be restricted within a certain range, thereby making it easier for the protrusion 124 of the wire harness separating tool to be inserted into the limiting hole 231 of the snap-fit ​​mounting bracket 20.

[0032] In some embodiments, the positioning part 114 is located at the end of the first clamp head 113 away from the first connecting part 112. The positioning part 114 is configured as a U-shaped snap-fit ​​structure 1140, which is used to snap onto the snap-fit ​​mounting bracket 20 for positioning the wire harness snap-fit ​​separation tool 10.

[0033] In the above embodiment, the U-shaped snap-fit ​​structure 1140 can be inserted into the plate-shaped third connecting part 22 of the snap-fit ​​mounting bracket 20. The U-shaped snap-fit ​​structure 1140 can be adapted to the third connecting part 22 of the snap-fit ​​mounting bracket 20 so that when the U-shaped snap-fit ​​structure 1140 is snapped into the third connecting part 22 of the snap-fit ​​mounting bracket 20, it can better achieve the positioning of the wire harness snap-fit ​​separation tool 10, and thus more accurately insert the protrusion 124 into the limiting hole 231 of the snap-fit ​​mounting bracket 20.

[0034] In some implementations, such as Figure 1 and Figure 2 As shown, the U-shaped snap-fit ​​structure 1140 is provided with a U-shaped opening 1141. When using the wire harness snap-fit ​​separation tool 10, the third connecting part 22 of the snap-fit ​​mounting bracket 20 can be inserted into the opening 1141 so that the U-shaped snap-fit ​​structure 1140 snaps into the third connecting part 22.

[0035] In the above embodiment, the opening 1141 can be adapted to the third connecting part 22, such that when the opening 1141 is fitted onto the third connecting part 22, the third connecting part 22 can be precisely engaged in the opening 1141. Of course, the engagement form between the opening 1141 and the third connecting part 22 is not limited to this.

[0036] Furthermore, it should be noted that the positioning part 114 can be constructed in other shapes depending on the shape of the third connecting part 22 of the snap-fit ​​mounting bracket 20. For example, when the third connecting part 22 is constructed as a triangular prism, the positioning part 114 can also be constructed as a V-shape that fits the triangular prism; there is no limitation here.

[0037] In some embodiments, the protrusion 124 provided on the second clamp head 123 extends away from the first clamp head 113, so that when the positioning part 114 of the wire harness buckle separating tool 10 is positioned and engaged with the buckle mounting bracket 20 and the first clamp head 113 and the second clamp head 123 are separated from each other to push the limiting part 321 of the wire harness buckle 32 out of the limiting hole 231, it is easier for the protrusion 124 to be inserted into the limiting hole 231 of the buckle mounting bracket 20.

[0038] In some embodiments, the protrusion 124 can be configured in any suitable form. For example, the protrusion 124 can be configured as a push rod 1240 for insertion into the limiting hole 231 of the snap-fit ​​mounting bracket 20. The push rod 1240 can be inserted into the limiting hole 231 of the snap-fit ​​mounting bracket 20 and push out the limiting portion 321 of the wire harness snap 32 from the limiting hole 231. The limiting portion 321 of the wire harness snap 32 can be configured in any shape that can fit the limiting hole 231. For example, the limiting portion 321 of the wire harness snap 32 can be configured as a cylinder.

[0039] Furthermore, it should be understood that the positioning part 114 can also be configured in any form that fits the limiting hole 231, such that the protrusion 124 can be inserted into the limiting hole 231 and the limiting part 321 can be pushed out of the limiting hole 231. There is no limitation here.

[0040] It should be understood that the harness clip separation tool 10 can be adapted to the disassembly of harness clips 32 of different models of high-pressure oil rail harnesses 30 by configuring the positioning part 114 and the protrusion 124 in different forms.

[0041] In some embodiments, the surface of the protrusion 124 may be provided with a drag-reducing layer to reduce frictional resistance, thereby reducing the friction between the protrusion 124 and the inner wall of the limiting hole 231 when the protrusion 124 is inserted into the limiting hole 231 of the snap-fit ​​mounting bracket 20, making it easier for the protrusion 124 to be inserted into the limiting hole 231.

[0042] In the above embodiments, the drag-reducing layer can be constructed in any suitable form. For example, the drag-reducing layer can be constructed as a chromium layer.

[0043] In some implementations, such as Figure 1 and Figure 2As shown, the wire harness clip release tool 10 also includes an elastic element 14. The two ends of the elastic element 14 are respectively connected to the first handle portion 111 and the second handle portion 121. The elastic element 14 is configured to compress when the first handle portion 111 and the second handle portion 121 are brought close together, so that when the first handle portion 111 and the second handle portion 121 are brought close together, the elastic element 14 can provide a spring force to either the first handle portion 111 or the second handle portion 121 away from the other, so as to facilitate the reset of the first handle portion 111 and the second handle portion 121 after they are brought close together.

[0044] In the above embodiment, in normal operation, the first handle portion 111 and the second handle portion 121 of the wire harness clip release tool 10 can be separated from each other, while the first clamp head 113 and the second clamp head 123 can be close to each other and fit together. When force is applied to the first handle portion 111 and the second handle portion 121 to bring them closer together, the first clamp head 113 and the second clamp head 123 move away from each other. At this time, the elastic member 14 is compressed. When the force is stopped and the first handle portion 111 and the second handle portion 121 are released, the first handle portion 111 and the second handle portion 121 separate from each other and reset under the action of the elastic member 14, thereby restoring the wire harness clip release tool 10 to normal operation.

[0045] In some embodiments, the elastic element 14 can be constructed in any suitable form. For example, as... Figure 1 and Figure 2 As shown, the elastic element 14 can be constructed as a spring 140. The spring 140 is disposed between the first handle portion 111 and the second handle portion 121. The two ends of the spring 140 are respectively connected to the first handle portion 111 and the second handle portion 121. When the first handle portion 111 and the second handle portion 121 approach each other, the spring 140 is compressed.

[0046] In some embodiments, the wire harness clip separation tool 10 further includes a rotating shaft 13, a first connecting part 112 is provided with a first through hole 115, and a second connecting part 122 is provided with a second through hole 125 corresponding to the first through hole 115. The rotating shaft 13 is rotatably inserted into the first through hole 115 and the second through hole 125 so that the first connecting part 112 and the second connecting part 122 are hinged, thereby allowing the first clamp arm 11 and the second clamp arm 12 to rotate relative to each other.

[0047] In some implementations, such as Figure 1 and Figure 2As shown, the rotating shaft 13 includes a shaft body 131 and limiting platforms 132 provided at both ends of the shaft body 131. The shaft body 131 is rotatably inserted into the first through hole 115 and the second through hole 125. One of the limiting protrusions provided at both ends of the shaft body 131 is located on the side of the first connecting part 112 away from the second connecting part 122, and the other is located on the side of the second connecting part 122 away from the first connecting part 112, so as to prevent the first connecting part 112 and the second connecting part 122 from being dislodged from the rotating shaft 13, thereby ensuring the normal use of the wire harness buckle separation tool 10.

[0048] In some embodiments, the first handle portion 111 and the second handle portion 121 are provided with anti-slip layers to facilitate gripping. The anti-slip layers can be constructed in any suitable form. For example, the anti-slip layer can be constructed as an anti-slip rubber layer, an anti-slip plastic layer, etc., and there is no limitation herein.

[0049] The following is in conjunction with the appendix Figures 1 to 4 An exemplary procedure for using the wire harness separating tool is described. First, the positioning part 114 of the wire harness clip separating tool 10, which has a U-shaped snap-fit ​​structure 1140 on the first clamp head 113, is snapped into the third connecting part 22 of the clip mounting bracket 20 for positioning the wire harness clip separating tool 10. Then, the operator can apply force to the first handle part 111 and the second handle part 121 to bring them closer together. Simultaneously, the first clamp head 113 and the second clamp head 121 move closer together. As the first clamp head 113 and the second clamp head 123 move away from each other, the position of the second clamp head 123 can be adjusted so that the push rod 1240 provided on the side of the second handle part 121 away from the first handle part 111 is inserted into the limiting hole 231 on the second mounting part 23 of the snap-fit ​​mounting bracket 20. Then the limiting part 321 of the wire harness snap-fit ​​32 is pushed out of the limiting hole 231, and then the wire harness snap-fit ​​32 is slid out of the second mounting part 23 of the snap-fit ​​mounting bracket 20 to remove the high-pressure oil rail wire harness from the snap-fit ​​mounting bracket 20.

However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0051] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction.
