Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive wiring harness fixing technology, specifically an automotive wiring harness fixing device. Background Technology
[0002] Automotive wiring harnesses are the main network of automotive circuits. Without wiring harnesses, there would be no automotive circuits. A wiring harness refers to a device made of copper-stamped contact terminals that are crimped with wires and cables, and then covered with a plastic-molded insulator.
[0003] A search revealed a Chinese patent document disclosing an electric vehicle wiring harness fixing device [Application No.: CN202420660308.8]. This electric vehicle wiring harness fixing device includes a clamping ring for fixing the wiring harness and a first connecting plate disposed at one end of the clamping ring, and a second connecting plate disposed at the other end of the clamping ring; wherein, in a ring-shaped state, the first connecting plate and the second connecting plate are parallel vertically, and a limiting pad is provided on the inner side of the first connecting plate, the limiting pad penetrating the second connecting plate.
[0004] The device disclosed in the patent can limit and fix multiple wire harnesses when in use. However, when the device covers multiple automotive wire harnesses, there are gaps between adjacent automotive wire harnesses and they rub against each other. The gaps between multiple automotive wire harnesses provide space for the movement of the automotive wire harnesses, which affects the stability of the device when fixing the automotive wire harnesses. Furthermore, the friction between adjacent wire harnesses can easily damage the external insulation of the wire harnesses. Utility Model Content
[0005] The purpose of this invention is to provide an automotive wiring harness fixing device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an automotive wiring harness fixing device, comprising an outer frame, and further comprising:
[0007] An arc-shaped frame is detachably connected to the inside of the outer frame. Several clamping blocks are fixedly connected to the inner wall of the arc-shaped frame, and a sealing mechanism is detachably connected to the surface of the clamping blocks.
[0008] A horizontal plate is fixedly connected to the surface of the outer frame. A limiting mechanism is installed on the top of the horizontal plate. A fixing plate is fixedly connected to the surface of the outer frame. An extension plate is fixedly connected to the surface of the fixing plate. Both the surface of the horizontal plate and the extension plate are provided with slots.
[0009] Preferably, the inner wall of the outer frame is provided with a hook and loop surface, and the surface of the arc-shaped frame is provided with a hook and loop hook surface, wherein the hook and loop surface is in contact with the hook and loop hook surface.
[0010] Preferably, the clamping blocks are made of sponge, and there is a gap between two adjacent clamping blocks.
[0011] Preferably, the sealing mechanism includes a sealing rod, a collar, a ring, and an auxiliary ring. The surface of the sealing rod is in contact with the surface of the clamping block. The collar is fixedly sleeved on one side of the surface of the sealing rod, and the ring is fixedly sleeved on the other side of the surface of the sealing rod. The auxiliary ring is detachably connected to the surface of the sealing rod, and the surface of the ring is in contact with both the inner wall of the auxiliary ring and the surface of the auxiliary ring.
[0012] Preferably, the limiting mechanism includes a back plate, an inclined plate, a connecting plate, and a limiting strip. The back plate is fixedly connected to the surface of the outer frame, the inclined plate is fixedly connected to the surface of the back plate, the connecting plate is fixedly connected to the top of the horizontal plate, the limiting strip is fixedly connected to the surface of the connecting plate, and the surface of the limiting strip is in contact with the surface of the inclined plate.
[0013] Preferably, protective strips are fixedly connected to the surfaces of both the outer frame and the cross plate, and the surfaces of the protective strips are all designed with an arc shape.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] In use, this invention can limit the movement of multiple automotive wiring harnesses by the squeezing of the clamping blocks. The sealing mechanism in this device can restrict the movement range of the automotive wiring harnesses, thereby reducing the possibility of mutual contact and friction between the wiring harnesses. In addition, after the automotive wiring harnesses are fixed, the device can initially limit the position of the outer frame through the limiting mechanism, so as to prepare for the subsequent installation of this device on the vehicle frame surface.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-5 As shown, an automotive wiring harness fixing device includes an outer frame 1. The inner wall of the outer frame 1 is provided with a Velcro surface 3. An arc-shaped frame 2 is detachably connected inside the outer frame 1. The surface of the arc-shaped frame 2 is provided with a Velcro hook surface. The Velcro surface 3 contacts the Velcro hook surface, and the engagement of the Velcro surface 3 and the Velcro hook surface ensures the stability of the arc-shaped frame 2 installed inside the outer frame 1. The arc-shaped frame 2 can be removed by the operator, allowing the device to fix thicker automotive wiring harnesses. Several clamping blocks 4 are fixedly connected to the inner wall of the arc-shaped frame 2. The clamping blocks 4 are made of sponge, and gaps are provided between adjacent clamping blocks 4. The wiring harness passes through the gap, and the clamping blocks 4 on both sides of the gap squeeze the wiring harness to limit its position. The surface of the clamping block 4 is detachably connected to a sealing mechanism 5. The sealing mechanism 5 can cover the surface of the clamping block 4 so that the wiring harness can be stably placed in the gap. A horizontal plate 7 is fixedly connected to the surface of the outer frame 1. A limiting mechanism 6 is installed on the top of the horizontal plate 7. A fixing plate 8 is fixedly connected to the surface of the outer frame 1. An extension plate 9 is fixedly connected to the surface of the fixing plate 8. The surfaces of the horizontal plate 7 and the extension plate 9 are both slotted. The operator first passes the bolt through the slot, and then installs the device on the surface of the vehicle frame by the cooperation of the bolt and nut.
[0024] The sealing mechanism 5 includes a sealing rod 51, a collar 52, a ring 53, and an auxiliary ring 54. The surface of the sealing rod 51 is in contact with the surface of the clamping block 4. The collar 52 is fixedly fitted on one side of the surface of the sealing rod 51, and the ring 53 is fixedly fitted on the other side of the surface of the sealing rod 51. The auxiliary ring 54 is detachably connected to the surface of the sealing rod 51. The surface of the ring 53 is in contact with the inner wall of the auxiliary ring 54 and the surface of the auxiliary ring 54. After the operator places the automotive wiring harness in the gap, the sealing rod 51 can be passed through the surface of the clamping block 4. Then, the operator passes the auxiliary ring 54 through the other end of the sealing rod 51. The collar 53 passing through the auxiliary ring 54 can restrict the position of the auxiliary ring 54. In this way, the position of the sealing rod 51 is reinforced by the cooperation of the collar 52 and the auxiliary ring 54, so that the gap can be blocked by the sealing rod 51. This can increase the stability of the automotive wiring harness placed in the gap. The material of the ring 53 is silicone.
[0025] The limiting mechanism 6 includes a back plate 61, an inclined plate 62, a connecting plate 63, and a limiting strip 64. The back plate 61 is fixedly connected to the surface of the outer frame 1, the inclined plate 62 is fixedly connected to the surface of the back plate 61, the connecting plate 63 is fixedly connected to the top of the horizontal plate 7, and the limiting strip 64 is fixedly connected to the surface of the connecting plate 63. The surface of the limiting strip 64 is in contact with the surface of the inclined plate 62. Through the cooperation between the limiting strip 64 and the connecting plate 63, the position between the inclined plate 62 and the back plate 61 can be reinforced, thereby initially limiting the state of the outer frame 1. Subsequently, the device can be installed by the workers using bolts and nuts. The cooperation of bolts and nuts can further increase the stability of the state and position of the outer frame 1.
[0026] Protective strips 10 are fixedly connected to the surfaces of the outer frame 1 and the cross plate 7. The surfaces of the protective strips 10 are all arc-shaped and make soft contact with the surface of the automotive wiring harness, thus protecting the surface of the automotive wiring harness.
[0027] Working principle: When fixing a single wire harness, the operator passes the automotive wire harness through the outer frame 1 and then squeezes the outer frame 1. At this time, the limiting strip 64 and the connecting plate 63 cooperate to restrict the state of the outer frame 1. The inner wall of the outer frame 1 is in contact with the surface of the wire harness. The outer frame 1 is fitted onto the surface of the wire harness. The operator passes the bolt through the slot and engages with the nut to connect and fix the device to the vehicle frame.
[0028] When fixing multiple thin automotive wiring harnesses, the operator can first install the arc frame 2 inside the outer frame 1 by using the hook and loop sides of the Velcro to cooperate with the hook and loop sides 3. Then, the operator can pass the automotive wiring harness through the gap on the surface of the clamping block 4 so that the position of the automotive wiring harness can be restricted by the compression of two adjacent clamping blocks 4. Then, the operator passes the sealing rod 51 through the surface of the clamping block 4 and fixes the position of the sealing rod 51 by cooperating with the auxiliary ring 54 and the collar 53. Accordingly, the gap on the surface of the clamping block 4 can be blocked by the sealing mechanism 5. The operator presses the outer frame 1 and initially restricts the state of the outer frame 1 by the limiting mechanism 6. Then, the operator can use bolts and nuts to install this device on the surface of the vehicle frame. The use of bolts and nuts is a mature existing technology and is well known to those skilled in the art, so it will not be described in detail here.
