[0002] In the prior art, due to the large number of electronic components in the automobile and the complex electronic circuit of the automobile, the storage battery for supplying power to the electronic components is generally connected to the automobile body by negative pole grounding, that is, the positive pole of the storage battery is connected to the electronic components through a wire harness, and the negative pole of the storage battery is connected to the automobile body. The automobile body is generally made of metal material and has conductivity itself. The electronic components are installed on the automobile body, thereby forming a loop from the positive pole of the storage battery to the wire harness, the electronic components, the automobile body, and finally to the negative pole of the storage battery. This arrangement can reduce the amount of wire harness used, reduce the complexity of the circuit, and protect the automobile body from corrosion. In the current technical solution, the negative pole of the storage battery is directly connected to the automobile body through the wire harness. However, in order to ensure safety, the electronic components need to be set to an open circuit state during installation. At this time, the wire harness needs to be separated from the automobile body. However, during the installation process of the electronic components, the wire harness may be accidentally touched and come into contact with the automobile body, causing the low-voltage circuit to close, which has a negative impact on the electronic components and poses a safety hazard.

[0023] The technical scheme of the present utility model will be further specifically described below through specific embodiments and in combination with the drawings:

[0024] Embodiment 1

[0025] As Figure 1The negative electrode wire harness body connecting device shown, including the connecting seat 1 for fixing on the vehicle body, wire harness 2 and ground bolt 3, one end of the wire harness 2 is used for connecting with the negative electrode of the battery, the other end of the wire harness 2 is installed on the connecting seat 1 and connected with it, the wire harness 2 is provided with the first mounting hole 21, the connecting seat 1 is provided with the second mounting hole 11, the ground bolt 3 passes through the first mounting hole 21, the second mounting hole 11 and is used for connecting with the vehicle body, the connecting seat 1 is of insulating material structure. The wire harness 2 is used for connecting the negative electrode of the battery and the vehicle body, the connecting seat 1 is used for containing the wire harness 2, the connecting seat 1 is fixed on the vehicle body, after the wire harness 2 is installed on the connecting seat 1, it is also fixed on the vehicle body, so that the position of the wire harness 2 is determined, avoiding the wire harness 2 position changing caused by accidentally touching the wire harness 2. The connecting seat 1 is of insulating material structure, the current cannot pass through the connecting seat 1, the connecting seat 1 is located between the wire harness 2 and the vehicle body, which separates the wire harness 2 and the vehicle body, so that the wire harness 2 cannot directly contact with the vehicle body to form a loop. The end of the wire harness 2 connected with the connecting seat 1 is provided with the first mounting hole 21, the connecting seat 1 is provided with the second mounting hole 11, the ground bolt 3 passes through the first mounting hole 21 and the second mounting hole 11 in sequence and is connected with the vehicle body. The ground bolt 3 is of metal material structure and has conductivity. After the ground bolt 3 passes through the first mounting hole 21 and the second mounting hole 11 and is connected with the vehicle body, the ground bolt 3 is in contact with the wire harness 2 and the vehicle body at the same time, so that the wire harness 2 and the vehicle body are connected to form a continuous loop, the current on the vehicle body can flow to the wire harness 2 through the ground bolt 3, and finally flows back to the negative electrode of the battery to form a complete loop, providing power for the operation of each electronic element. When it is necessary to install or dismount the electronic element, the ground bolt 3 only needs to be pulled out of the first mounting hole 21 and the second mounting hole 11, the wire harness 2 and the vehicle body will be disconnected, resulting in the original circuit being disconnected, so as to ensure that the electronic element will not have current passing through during the installation process on the vehicle body, and will not be adversely affected by the accidental connection of the circuit during the installation process, and the safety hidden danger caused by the accidental connection of the circuit is avoided. When the electronic element is installed, the ground bolt 3 is passed through the first mounting hole 21 and the second mounting hole 11 again and connected with the vehicle body, the loop of the wire harness 2 and the vehicle body is reconnected, and the electronic element can work normally.

[0026] As Figure 2As shown, the connecting seat 1 includes a bottom plate 12 for fixedly mounting on the vehicle body, the second mounting hole 11 is arranged on the bottom plate 12, the upper surface of the bottom plate 12 abuts against the wire harness 2, and the edges of the bottom plate 12 extend upward to form side plates 13, and the side plate 13 on one side is provided with a notch 14 for the wire harness 2 to pass through. The bottom plate 12 in the connecting seat 1 is fixedly mounted on the vehicle body, on the one hand, to fix the position of the connecting seat 1, and on the other hand, the upper surface of the bottom plate 12 abuts against the wire harness 2 to isolate the wire harness 2 from the vehicle body. The edges of the bottom plate 12 extend upward to form side plates 13, so that the connecting seat 1 forms a semi-enclosed structure, and the wire harness 2 is arranged in the semi-enclosed structure, on the one hand, to isolate the wire harness 2 from the outside to a certain extent, thereby protecting the wire harness 2. On the other hand, the semi-enclosed space limits the position of the wire harness, and only when the wire harness 2 is subjected to a force towards the upper side of the connecting seat 1 can the wire harness 2 be removed from the semi-enclosed structure. Since the wire harness 2 is blocked by the structure of the vehicle body below, it is difficult for other objects to extend into the lower side of the wire harness 2 to remove the wire harness 2 from the semi-enclosed space, thereby ensuring the stability of the position of the wire harness 2 and preventing the wire harness 2 from falling off the connecting seat 1, thereby achieving the function of installing the wire harness 2. The side plate 13 on one side is provided with a notch 14 for placing the wire harness 2, and the notch 14 leaves a space for placing the wire harness 2.

[0027] As shown in Figure 2 The inner side of the side plate 13 on both sides of the notch 14 is provided with a clamping groove 15, and the end of the wire harness 2 connected with the connecting seat 1 is provided with a clamping block 22, and the clamping block 22 is clamped with the clamping groove 15. The clamping groove 22 plays a role in assisting to determine the position of the wire harness 2. When the clamping block 22 on the wire harness 2 is fixed with the clamping groove 15, the position of the clamping block 22 in the horizontal direction is limited in the clamping groove 15, thereby limiting the movement of the position of the wire harness 2, and playing a role in determining the position of the wire harness 2 and preventing the wire harness 2 from moving or rotating in the connecting seat 1. At the same time, after the clamping block 22 is clamped with the clamping groove 15, there is a friction force between the clamping block 22 and the clamping groove 15, which limits the movement of the clamping block 22 in the clamping groove 15, thereby limiting the upward movement of the wire harness 2 out of the connecting seat 1.

[0028] Embodiment 2

[0029] This embodiment is similar to the above-mentioned embodiment 1, and the difference lies in that, as shown in Figure 3 The bottom surface of the bottom plate 12 is provided with a buckle 16 for inserting into the process hole on the vehicle body. The buckle 16 can use the process hole originally existing on the vehicle body to firmly fix the bottom plate 12 on the vehicle body, thereby ensuring the stable installation of the connecting seat 1.

[0030] As shown in Figure 3As shown, the snap fastener 16 is made of an elastic material and includes a connector 161 and a snap-fit ​​component 162. The two ends of the connector are connected to the base plate 12 and the snap-fit ​​component, respectively. The snap-fit ​​component 162 is a cone-shaped structure with a cross-sectional area decreasing towards the distance from the connector 161. The cross-sectional area of ​​the snap-fit ​​component 162 near the connector 161 is larger than the area of ​​the bodywork hole, while the cross-sectional area of ​​the connector 161 is smaller than the area of ​​the bodywork hole. The snap fastener 16 is made of an elastic material, allowing it to undergo a certain degree of recoverable deformation. The snap fastener 16 includes a snap-fit ​​component 162 and a connector 161, wherein the snap-fit ​​component 162 is used to snap onto the body, and the connector 161 is used to connect the snap-fit ​​component 162 to the base plate 12. The snap-fit ​​component 162 is a cone-shaped structure with a cross-sectional area decreasing away from the connector 161. When installing the connector 1, the snap-fit ​​162 is aligned with the process hole on the vehicle body, and then a force is applied to the connector 1 in the direction of the vehicle body. Under the push of the force, the snap-fit ​​162 inserts into the process hole of the vehicle body. The end of the snap-fit ​​component 162 with the smaller cross-sectional area enters the process hole first, and then, under the action of the force, the snap-fit ​​component 162 continues to insert into the process hole. As the cross-sectional area of ​​the snap-fit ​​component 162 increases, the contact with the process hole becomes increasingly tighter, thus requiring a greater force to push the connector 1. At this point, the portion of the snap-fit ​​component 162 already inserted into the process hole restricts the position of the snap-fit ​​component 162, preventing it from sliding out of the process hole under the action of the force. Under the action of the force and the process hole, the snap-fit ​​component 162 undergoes a certain degree of deformation to smoothly pass through the process hole. Once the snap-fit ​​162 has completely passed through the process hole, it is no longer restricted by the process hole, and the snap-fit ​​162, which had originally deformed, returns to its original shape. At this point, the cross-sectional area of ​​the snap-fit ​​162 near the connector 161 is larger than the area of ​​the body process hole, preventing the snap-fit ​​162 from passing through the process hole, thus achieving the snap-fit ​​between the buckle 16 and the body process hole. The cross-sectional area of ​​the connector 161 is smaller than the area of ​​the body process hole, allowing the connector 161 to pass through the body process hole without obstruction, connecting the base plate 12 and the snap-fit ​​162.

[0031] like Figure 3 As shown, at least two clips 16 are provided. A single clip 16 is insufficient to secure the connector 1, and the connector 1 may still rotate around a single clip. Therefore, at least two clips 16 are required to ensure that the connector 1 does not rotate.

[0033] This embodiment is similar to Embodiment 1 above, except that, as Figure 1As shown in the figure, the wire harness 2 comprises a wire harness body 23, the wire harness body 23 is provided with a first mounting head 24 near one end of the connecting seat 1, the first mounting hole 21 is opened on the first mounting head 24, the clamping block 22 is arranged on both sides of the first mounting head 24, the other end of the wire harness body 23 is provided with a second mounting head 25, and the second mounting head 25 is connected with the negative electrode of the storage battery. The wire harness body 23 is a rod-shaped structure for connecting the storage battery and the vehicle body. The wire harness body 23 is provided with the first mounting head 24 and the second mounting head 25 at both ends respectively, wherein the first mounting head 24 is used for connecting with the connecting seat 1, and the second mounting head 25 is used for connecting with the negative electrode of the storage battery.

[0035] As shown in the figure, Figure 1 The outer wall surface of the wire harness body 23 is wrapped with rubber, and the rubber is an insulating material structure. The rubber has a protective effect on the wire harness body 23, and can avoid the wire harness body 23 from being accidentally contacted with the outside world to cause electric leakage or short circuit and produce safety hazards.

[0036] As shown in the figure, Figure 1 The outer peripheral surface of the grounding bolt 3 is a threaded surface, and the grounding bolt 3 is threadedly connected with the process hole of the vehicle body. The grounding bolt 3 is connected with the vehicle body through threads, and the threaded connection is stable and convenient to disassemble and assemble, and only needs to be rotated in different directions to install and disassemble.
