DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In actual use of an existing safety and compression-resistant automobile wiring harness, even if the clamping force and friction between the clamping block and the clamping slot are increased by the anti-skid pad, during the driving of the car, due to vibration and bumps, the clamping block and the clamping slot between the already clamped left protection block and the right protection block may become slightly loose. This looseness may gradually accumulate under continuous vibration, and may eventually cause the clamping block to slip out of the clamping slot, so that the left protection block and the right protection block are no longer tightly fixed, affecting the protection of the connection between the wiring harness body and the connector. Therefore, a more reliable clamping structure is used to protect the connection between the wiring harness body and the connector.

[0033] Embodiment 1:

[0034] like Figures 1 to 5 The utility model provides a safe and pressure-resistant automobile wiring harness.

[0035] Specifically, by Figure 1-2 A safe and pressure-resistant automotive wiring harness is provided, comprising a wiring harness body 1, a first clamping block 4, a second clamping block 5, a connector 3 and a clamping structure 2, wherein the clamping structure 2 is located between the first clamping block 4 and the second clamping block 5 and connects the first clamping block 4 with the second clamping block 5, and the clamping structure 2 comprises a connecting frame 201 installed on the top of the second clamping block 5, the inner wall of the connecting frame 201 is connected to a connecting rod 202, the outer wall of the connecting rod 202 is rotatably connected to a Z-shaped clamping block 203, the top of the Z-shaped clamping block 203 is connected to a connecting block 204, and the inner bottom wall of the connecting frame 201 is installed with a plurality of Coil spring 205, the top of the coil spring 205 is connected to the bottom of the Z-shaped block 203, a pressing block 206 is arranged inside the connecting frame 201, and a plurality of telescopic springs 207 are installed on the inner bottom wall of the connecting frame 201, the top of the telescopic spring 207 is connected to the bottom of the pressing block 206, the pressing block 206 is located below one end of the Z-shaped block 203, a clamping block 208 is installed at the bottom of the first clamping block 4, the clamping block 208 is provided with a clamping groove 209 which is clamped with the Z-shaped block 203, and the bottom end of the clamping block 208 corresponds to the top of the pressing block 206.

[0036] When the connection between the wiring harness body 1 and the connector 3 is located between the first clamping block 4 and the second clamping block 5, the first clamping block 4 is rotated to make one end of the first clamping block 4 close to the connecting frame 201. When the clamping block 208 enters the interior of the connecting frame 201, one end of the clamping block 208 will contact the pressing block 206 and squeeze the pressing block 206 toward the bottom end of the connecting frame 201. At the same time, the telescopic spring 207 will shrink due to the squeezing of the pressing block 206. When the arc-shaped end of the Z-shaped clamping block 203 is clamped into the inside of the clamping groove 209, the clamping block 208 can be clamped by the Z-shaped clamping block 203 to prevent the clamping block 208 from being easily moved out of the connecting frame 201. When one end of the Z-shaped clamping block 203 clamps the clamping block 208, the wiring harness body 1 has been firmly fixed between the first clamping block 4 and the second clamping block 5.

[0037] When it is necessary to separate the first clamping block 4 from the second clamping block 5, it is only necessary to press the connecting block 204 downward to rotate the Z-shaped block 203 along the outer wall of the connecting rod 202. When one end of the Z-shaped block 203 moves downward, the end of the Z-shaped block 203 located inside the slot 209 will move upward. Because the top of one end of the Z-shaped block 203 is arc-shaped, it can easily slide out of the slot 209 when the arc-shaped end of the Z-shaped block 203 moves upward. After one end of the Z-shaped block 203 releases the fixation of the clamping block 208, the clamping block 208 can be moved out from the inside of the connecting frame 201. At the same time, the telescopic spring 207 bounces the pressing block 206 back to its original position, facilitating the next entry of the clamping block 208.

[0038] Further:

[0039] like Figure 2 and Figure 4 It is shown that a connecting plate 10 is installed on the top of the connecting block 204, and the connecting plate 10 is located above the connecting frame 201. Square sliding grooves 11 for the connecting plate 10 to slide up and down are opened on both sides of the connecting frame 201, and the square sliding grooves 11 are located below the connecting plate 10.

[0040] The connecting plate 10 is used to increase the contact area of ​​the top of the connecting block 204, so that when the connecting block 204 needs to be pressed, the operator can press the connecting block 204 to move downward without putting his hand into the connecting frame 201. Because the connecting plate 10 itself is relatively long, when the connecting plate 10 is pressed to move downward, the connecting plate 10 will contact the top of the connecting frame 201, thereby causing the connecting plate 10 to be unable to move downward. The square slide groove 11 provides space for the connecting plate 10 to move downward, so that the connecting plate 10 can move downward with the connecting block 204.

[0041] Embodiment 2:

[0042] Further:

[0043] like Figure 3 It is shown that the outer wall of the wiring harness body 1 is connected to a mica glass fiber high temperature resistant layer 18 , the outer wall of the mica glass fiber high temperature resistant layer 18 is connected to a glass fiber pressure resistant layer 17 , and the outer wall of the glass fiber pressure resistant layer 17 is connected to an insulating tape 16 .

[0044] The mica glass fiber high temperature resistant layer 18 is a material with excellent high temperature stability, which can protect the wiring harness body 1 in a high temperature environment and prevent the wiring harness body 1 from being damaged or its performance deteriorated. The glass fiber pressure-resistant layer 17 provides pressure-resistant protection and is a high-strength and wear-resistant material. Therefore, it can enhance the pressure resistance of the wiring harness body 1 and prevent the wiring harness body 1 from being damaged when it is subjected to external pressure. The insulating tape 16 is the outermost layer, and its main function is to provide electrical insulation and mechanical protection. The insulating tape 16 can effectively prevent current leakage and ensure the safe use of the wiring harness body 1. At the same time, the insulating tape 16 can also provide a certain mechanical strength to protect the insulating tape 16 from daily wear and damage.

[0045] Further:

[0046] like Figure 1 It is shown that the first clamping block 4 and the second clamping block 5 are both provided with a V-shaped groove 6, the two V-shaped grooves 6 correspond to each other, the wiring harness body 1 is located between the two V-shaped grooves 6, the first clamping block 4 and the second clamping block 5 are located at the connection between the wiring harness body 1 and the connector 3, the inner wall of the V-shaped groove 6 is integrally formed with rubber anti-slip particles, the rubber anti-slip particles are against the outer wall of the insulating tape 16, and the wiring harness body 1 is located inside the V-shaped groove 6.

[0047] The V-shaped groove 6 provides space for the wiring harness body 1, so that the first clamping block 4 and the second clamping block 5 can wrap the connection between the wiring harness body 1 and the connector 3 through the V-shaped groove 6 when fixing the connection between the wiring harness body 1 and the connector 3. Because the rubber anti-slip particles are relatively soft, the rubber anti-slip particles can increase the friction between the V-shaped groove 6 and the insulating tape 16 without damaging the surface of the insulating tape 16. The insulating tape 16 is located at the outermost layer of the wiring harness body 1, so the outer wall of the insulating tape 16 will be in direct contact with the rubber anti-slip particles.

[0048] Further:

[0049] Specifically, Figure 1 It is shown that a connecting ring 8 is sleeved on the outer wall of the insulating tape 16, and a clamping ring 7 and a circular protrusion 9 are installed on the outer wall of the connecting ring 8. The clamping ring 7 is clamped with the circular protrusion 9, and the material of the clamping ring 7 is elastic material.

[0050] The circular protrusion 9 and the clamping ring 7 are respectively fixed on both sides of the wiring harness body 1 through the connecting ring 8. In order to avoid multiple wiring harness bodies 1 from being mixed together and difficult to distinguish, the circular protrusion 9 on one side of one wiring harness body 1 is aligned with the clamping ring 7 on the other side of the wiring harness body 1, and the circular protrusion 9 is inserted into the inside of the clamping ring 7. At this time, the two adjacent wiring harness bodies 1 can be connected together. In this way, multiple wiring harness bodies 1 can be connected together in turn, so that the multiple wiring harness bodies 1 can be arranged more neatly and are easy to distinguish.

[0051] Further:

[0052] like Figure 1 and Figure 5 It is shown that a mounting block 12 is installed at the bottom of the first clamping block 4, a fixing frame 13 is installed at the top of the second clamping block 5, a rotating rod 14 is inserted into the fixing frame 13, the mounting block 12 is rotatably connected to the outer wall of the rotating rod 14, and the mounting block 12 is located inside the fixing frame 13.

[0053] One end of the first clamping block 4 is connected to a rotating rod 14 at one end of the second clamping block 5 through a mounting block 12. The fixing frame 13 is used to fix the position of the rotating rod 14. The rotating connection between the mounting block 12 and the rotating rod 14 allows the first clamping block 4 to rotate around the rotating rod 14 to prevent the first clamping block 4 from detaching from the top of the second clamping block 5.

[0054] Further:

[0055] like Figure 5 It is shown that both ends of the rotating rod 14 extend to the outside of the fixing frame 13, and the outer wall of the rotating rod 14 is integrally formed with a thread line, the thread line is located outside the fixing frame 13, the thread line is threadedly connected with a nut 15, and the nut 15 is against the outer wall of the fixing frame 13.

[0056] Part of the areas at both ends of the rotating rod 14 are located outside the fixing frame 13, and the threads on the outer walls of these areas allow the nuts 15 to be screwed on them. The two nuts 15 are screwed to tighten the nuts 15 against the outer wall of the fixing frame 13, so as to prevent the rotating rod 14 from rotating along the mounting block 12 when the mounting block 12 rotates along the outer wall of the rotating rod 14, thereby preventing the rotating rod 14 from sliding out of the fixing frame 13.

[0057] Working principle:

[0058] When the connection between the wiring harness body 1 and the connector 3 is located between the first clamping block 4 and the second clamping block 5, the first clamping block 4 is rotated to make one end of the first clamping block 4 close to the connecting frame 201. When the clamping block 208 enters the interior of the connecting frame 201, one end of the clamping block 208 will contact the pressing block 206 and squeeze the pressing block 206 toward the bottom end of the connecting frame 201. At the same time, the telescopic spring 207 will shrink due to the squeezing of the pressing block 206. When the arc-shaped end of the Z-shaped clamping block 203 is clamped into the inside of the clamping groove 209, the clamping block 208 can be clamped by the Z-shaped clamping block 203 to prevent the clamping block 208 from being easily moved out of the connecting frame 201. When one end of the Z-shaped clamping block 203 clamps the clamping block 208, the wiring harness body 1 has been firmly fixed between the first clamping block 4 and the second clamping block 5.

[0059] When it is necessary to separate the first clamping block 4 from the second clamping block 5, it is only necessary to press the connecting block 204 downward to rotate the Z-shaped block 203 along the outer wall of the connecting rod 202. When one end of the Z-shaped block 203 moves downward, the end of the Z-shaped block 203 located inside the slot 209 will move upward. Because the top of one end of the Z-shaped block 203 is arc-shaped, it can easily slide out of the slot 209 when the arc-shaped end of the Z-shaped block 203 moves upward. After one end of the Z-shaped block 203 releases the fixation of the clamping block 208, the clamping block 208 can be moved out from the inside of the connecting frame 201. At the same time, the telescopic spring 207 bounces the pressing block 206 back to its original position, facilitating the next entry of the clamping block 208.

[0060] The mica glass fiber high temperature resistant layer 18 is a material with excellent high temperature stability, which can protect the wiring harness body 1 in a high temperature environment and prevent the wiring harness body 1 from being damaged or its performance deteriorated. The glass fiber pressure-resistant layer 17 provides pressure-resistant protection and is a high-strength and wear-resistant material. Therefore, it can enhance the pressure resistance of the wiring harness body 1 and prevent the wiring harness body 1 from being damaged when it is subjected to external pressure. The insulating tape 16 is the outermost layer, and its main function is to provide electrical insulation and mechanical protection. The insulating tape 16 can effectively prevent current leakage and ensure the safe use of the wiring harness body 1. At the same time, the insulating tape 16 can also provide a certain mechanical strength to protect the insulating tape 16 from daily wear and damage.

[0061] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
