Description

A car battery harness connection device Technical Field

[0001] This utility model relates to the field of automotive parts, and more specifically, to an automotive battery harness connection device. Background Technology

[0002] A battery sensor is typically installed on the negative terminal of a car battery, secured with an M10 nut. Therefore, when the vehicle is not in use for an extended period or when the negative terminal needs to be disconnected for repairs due to a malfunction, an appropriate wrench is required. However, some cars do not come equipped with a suitable wrench, making it extremely inconvenient for the owner to disconnect the negative battery terminal.

[0003] Existing technology discloses a connection and fixing structure for the positive and negative terminals of an automotive battery, including a fastening clamp, a connecting bolt, a limiting nut, a rivet shaft, and a switch wrench. The fastening clamp has a first connecting piece and a second connecting piece at its open end. One end of the connecting bolt passes through the first connecting piece and is connected to the rivet shaft. The other end of the connecting bolt passes through the second connecting piece and is connected to the limiting nut. One end of the switch wrench is movably connected to the rivet shaft. The switch wrench can rotate around the rivet shaft, causing deformation between the first and second connecting pieces, thereby allowing the fastening clamp to be tightened onto or detached from the battery terminals. The solution provided by this invention can effectively improve the efficiency of assembling and disassembling the positive and negative terminals of the battery, reduce the workload of workshop operators and customers, effectively eliminate the need for related electric and pneumatic tools, and reduce costs.

[0004] However, with this type of connection device, when the vehicle is moving, it will be affected by road conditions and bumps. Since the switch wrench is in a self-locking state, it is easy for the wrench to break out of the locked state under prolonged bumps, causing the wiring harness to fall off and affecting the use of the vehicle. Summary of the Invention

[0005] The purpose of this invention is to overcome the problem that the wrench in the existing battery harness connection structure is prone to disengaging from the locked state after long-term vibration, and to provide an automotive battery harness connection device that prevents the wrench from disengaging from the locked state and improves stability.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A car battery wiring harness connection device is provided, including a clamp, a wrench, a connector, a limiting member, an anti-disengagement member, and a fixing plate connected to the clamp. The clamp has an internal clamping opening for fixing the wiring harness. The open end of the clamp has a first connecting piece and a second connecting piece, both of which have through holes. The connector passes through the through holes. The wrench is rotatably connected to the connector. When the wrench is in the unlocked state, the wrench abuts against the first connecting piece, and the limiting member abuts against the second connecting piece. When the wrench is in the locked state, the wrench presses against the first connecting piece, and the limiting member presses against the second connecting piece. The anti-disengagement member is disposed on the wrench or the fixing plate. When the wrench is in the locked state, the anti-disengagement member is used to lock the wrench and the fixing plate.

[0008] This utility model discloses a car battery wiring harness connection device. The device is installed at the battery terminals. When connecting the wiring harness to the battery, the device is kept loose, and the wiring harness is inserted into the terminal. Then, the wrench can be turned. Under the action of the wrench and the limiting component, the first and second connecting pieces are compressed and deformed, and the entire clamp also deforms, causing the inner diameter of the clamp to shrink. When the wrench is turned to the locking position, it self-locks, and the clamp shrinks to its minimum, compressing the terminal and firmly fixing the wiring harness inside. This effectively improves the efficiency of assembling and disassembling the positive and negative battery wiring harnesses, reduces the workload of workshop operators and customers, effectively eliminates the need for related electric and pneumatic tools, and reduces costs. After the wrench is locked, a locking component can be used to connect the wrench and the fixing plate. In this way, when the vehicle experiences bumps during driving, the anti-detachment component can restrain the wrench, preventing it from disengaging from the locked state and causing the wiring harness to fall off, thus improving stability.

[0009] Furthermore, one end of the anti-detachment component is connected to the fixing plate, and the other end is detachably connected to the wrench. When the wrench is in the locked position, simply separate one end of the anti-detachment component from the wrench and then turn the wrench to release the locked state, making disassembly and assembly convenient.

[0010] Furthermore, the anti-detachment component is an elastic component, and the direction of the elastic force of the elastic component is perpendicular to the rotation axis of the wrench. By selecting an elastic component with moderate elasticity as the anti-detachment component, when disassembling the wire harness, it is not necessary to separate one end of the anti-detachment component from the elastic component. Since the human hand has relatively strong strength, it can overcome the elastic force of the elastic component to turn the wrench. When the wire harness is loosened and removed, the wrench is released, and the wrench can return to the locked state under the action of the elastic force. The same principle applies when installing the wire harness. The wrench is turned to insert the wire harness, and after the wire harness is inserted, the wrench is released to fix the wire harness, realizing automatic springback and improving convenience.

[0011] Furthermore, the fixed plate has a connecting portion, the wrench has a connecting groove, one end of the elastic element has an annular portion that is movably connected to the connecting portion, and the other end has a hook portion that engages with the inner wall of the connecting groove. The annular portion is movably connected to the connecting portion, which does not restrict the direction of the elastic force of the elastic element, ensuring that the direction of the elastic force of the elastic element can change with the rotation angle of the wrench. The hook portion can engage with the connecting groove, making disassembly and assembly more convenient.

[0012] Furthermore, the end of the wrench furthest from the axis of rotation is provided with a grip portion, and the grip portion is covered with an anti-slip sleeve. Both sides of the anti-slip sleeve have through grooves, the openings of which coincide with the openings of the connecting groove. The anti-slip sleeve enhances the wrench's anti-slip performance and prevents it from slipping out of the hand.

[0013] Furthermore, the end of the wrench connected to the clamp is provided with a cam portion. When the wrench is in the locked state, the distance from the contact point between the cam portion and the clamp to the rotation axis is greater than the distance from the contact point between the cam portion and the clamp to the rotation axis when the wrench is in the unlocked state. The cam portion has a smoother transition, making it easier to rotate the wrench. When rotated to the locked position, the first connecting piece undergoes a large deformation. When the force is stopped from being rotated, the first connecting piece returns to its original shape, which generates a reaction force on the cam portion, fixing the cam portion in place and achieving self-locking.

[0014] Furthermore, the wrench has a rotating groove perpendicular to the rotation axis, and one end of the connecting member is located within the rotating groove. Compared to having the connecting member located on one side of the cam portion, this arrangement makes the wrench rotation more stable and the force on the first connecting piece more even.

[0015] Furthermore, a rubber gasket is provided at the connection between the wrench and the clamp. The rubber gasket provides cushioning and reduces wear on the clamp.

[0016] Furthermore, the mounting plate is equipped with a sensor for detecting the battery voltage. The sensor can detect the battery voltage, is connected to the disassembly device, and is detachable and easy to replace.

[0017] Furthermore, the connector is provided with a threaded portion, and the limiting member is threadedly connected to the threaded portion. The threaded connection is easy to assemble and disassemble.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. When the wrench is in the locked position, the anti-disengagement component can restrain the wrench and prevent the wrench from disengaging due to bumps during vehicle operation, thereby preventing the wiring harness from coming loose and improving stability.

[0020] 2. Selecting elastic components with moderate elasticity as anti-slip components enables automatic rebound and improves convenience;

[0021] 3. The grip is fitted with an anti-slip sleeve to enhance the wrench's anti-slip performance and prevent it from slipping out of your hand. Attached Figure Description

[0029] Example 1

[0030] A car battery wiring harness connection device, as shown in Figures 1-3, includes a clamp 100, a wrench 200, a connector 300, a limiting member 400, an anti-detachment member 500, and a fixing plate 600 connected to the clamp 100. The clamp 100 has a circular clamping opening 110 inside for fixing the wiring harness. The open end of the clamp 100 has a first connecting piece 120 and a second connecting piece 130, both of which have through holes. One end of the connector 300 has a pivot hole 310, and the other end passes through the two through holes and connects to the limiting member 400. The wrench 200 has a rotating groove 260 radially along the pivot portion 210, and one end of the connector 300 is located within the rotating groove 260. The wrench 200 is connected to the pivot portion 210. In this embodiment, the pivot portion 210 is a rivet, which passes through the pivot hole 310 and connects to the connector 300. The rotating connection is 0. The rotating shaft 210 is riveted to the wrench 200. When the wrench 200 is in the unlocked state, the wrench 200 abuts against the first connecting piece 120, and the limiting member 400 abuts against the second connecting piece 130. When the wrench 200 is in the locked state, the wrench 200 presses against the first connecting piece 120, and the limiting member 400 presses against the second connecting piece 130. The anti-disengagement member 500 is an elastic member 510. In this embodiment, the elastic member 510 is a straight spring. The fixing plate 600 is provided with a connecting part 610. In this embodiment, the connecting part 610 is a connecting post formed between two openings. The wrench 200 is provided with a connecting groove 220. One end of the elastic member 510 is provided with an annular part 511 and is movably connected to the connecting part 610. The other end is provided with a hook part 512 and is engaged with the inner wall of the connecting groove 220. The elastic force direction of the elastic member 510 is perpendicular to the axis of the rotating shaft 210.

[0031] The working principle of this embodiment is as follows:

[0032] This utility model discloses a car battery wiring harness connection device, as shown in Figure 4. The device is installed at the battery terminal 900. When connecting the wiring harness to the battery, the device is kept loose, and the wiring harness is inserted into the terminal 900. Then, the wrench 200 is turned. Under the action of the wrench 200 and the limiting member 400, the first connecting piece 120 and the second connecting piece 130 are compressed and deformed. The entire clamp 100 also deforms, and the inner diameter of the clamp 110 contracts. When the wrench 200 is rotated to the locking position, it self-locks, and the clamp 110 contracts to its minimum, compressing the terminal 900 and firmly fixing the wiring harness within it. This effectively improves the efficiency of assembling and disassembling the positive and negative battery wiring harnesses, reducing workshop workload. This reduces the workload for operators and customers, effectively eliminating the need for related electric and pneumatic tools and lowering costs. After the wrench 200 is locked, the hook 512 at one end of the elastic element 510 can be fitted onto the inner wall of the connecting groove 220. When the vehicle experiences bumps during operation, the anti-disengagement element 500 can restrain the wrench 200, preventing it from disengaging from the locked state and causing the wire harness to fall off, thus improving stability. In addition, the anti-disengagement element 500 has another method of use. When disassembling the wire harness, it is not necessary to remove the hook 512. Simply pull the wrench 200 to widen the clamp 110, remove the wire harness, and then release the wrench 200. At this time, the wrench 200 will spring back under the pull of the spring. When inserting the wire harness, simply pull the wrench 200 open and then release it. The wrench 200 will spring back and clamp the wire harness.

[0033] The beneficial effects of this embodiment are as follows:

[0034] This connection device can effectively improve the efficiency of assembling and disassembling the positive and negative terminals of the battery, reduce the workload of workshop operators and customers, effectively eliminate the need for related electric and pneumatic tools, and reduce costs. When the wrench 200 is in the locked state, the anti-disengagement component 500 can restrain the wrench 200 to prevent the wrench 200 from disengaging from the locked state due to bumps during vehicle operation, thereby preventing the wiring harness from falling off and improving stability. The selection of an elastic component 510 with moderate elasticity as the anti-disengagement component 500 enables automatic rebound and improves convenience.

[0035] In addition, the anti-slip component 500 can also be fixed at one end to the wrench 200 and detachably connected to the fixing plate 600 at the other end. The anti-slip component 500 can also be a snap-fit ​​instead of an elastic component 510.

A grip portion 240 is provided at the end of the wrench 200 away from the rotation axis. An anti-slip sleeve 250 is fitted on the outside of the grip portion 240. Through grooves are provided on both sides of the anti-slip sleeve 250, and the groove openings of the through grooves coincide with the groove openings of the connecting groove 220.

[0038] The working principle of this embodiment is as follows:

[0039] The cam portion 230 has a smoother transition, making it easier to rotate the wrench 200. When rotated to the locking position, the first connecting piece 120 undergoes a large deformation. When the force is stopped from being turned, the first connecting piece 120 will generate a reaction force to return to its original shape, thus fixing the cam portion 230 in place and achieving self-locking. The anti-slip sleeve 250 can enhance the anti-slip performance of the wrench 200 and prevent it from slipping out of the hand.

[0040] The remaining working principles of this embodiment are the same as those of Embodiment 1.

[0041] In addition, the wrench 200 may not have a cam part 230, and the outer periphery of the wrench 200 may be polygonal, elliptical or other shapes.
