Description

Technical Field

[0001] This utility model relates to the field of automotive wiring components technology, specifically to an automotive high-voltage electrical connection harness with a spare connector. Background Technology

[0002] Utility model patent CN215934008U discloses a high-voltage electrical connection harness structure for automobiles with a spare connector. The structure includes a main harness, with first insulating connectors fixedly installed at both ends of the main harness. A first insulating plug housing is fixedly installed on each of the first insulating connectors. Secondary harnesses are electrically connected to the wires at both ends of the main harness. A second insulating connector is fixedly installed at the end of each secondary harness away from the main harness, and a second insulating plug housing is fixedly installed on the second insulating connector. An anti-detachment component is provided between the end wire of the secondary harness connecting to the main harness and the main harness. The anti-detachment component includes an anti-detachment rubber block fixedly installed between the main harness and the secondary harness. The anti-detachment rubber block effectively limits the connection between the main and auxiliary wire harnesses, preventing the auxiliary wire harness from tearing from the main harness. Insulating wire loops are located at both ends of the anti-detachment rubber block, one inside the auxiliary wire harness and the other inside the main wire harness. These insulating wire loops limit the anti-detachment rubber block, ensuring it is unlikely to fall off. An insulating protrusion is provided between the insulating wire loop and the anti-detachment rubber block, increasing the contact area and making the structure of the insulating wire loop fixed to the anti-detachment rubber block more secure and stable. Multiple built-in pull rods arranged linearly and at equal intervals are provided between the two insulating wire harness rings. The built-in pull rods pass through the insulating protrusion and the anti-detachment rubber block. The built-in pull rods limit the distance between the two insulating wire harness rings, further ensuring that the two insulating wire harness rings are not prone to outward separation, and making the connection between the secondary wire harness and the main wire harness more secure and stable.

[0003] The above-mentioned patents have the following shortcomings:

[0004] As shown in Figure 6 of the instruction manual, when the first connector 3 is damaged but the first branch line 11 is not damaged, and the second connector 4 is not damaged but the second branch line 12 is damaged, the second connector 4 can be installed on the first branch line 11 and it can be used normally. However, in the above embodiment, the connectors cannot be disassembled and replaced, so the use is limited. Utility Model Content

[0005] In view of the problems existing in a current automotive high-voltage electrical connection harness with a spare connector, this utility model is proposed.

However, in the above embodiment, the connector cannot be disassembled and replaced, so its use is limited.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Example 1:

[0026] This utility model provides an automotive high-voltage electrical connection harness with a spare connector. Please refer to [link / reference]. Figure 1-3 The system includes a wire harness body 1. One end of the wire harness body 1 has a first branch line 11 and a second branch line 12, and the other end of the wire harness body 1 has a third branch line 13 and a fourth branch line 14. The ends of the first branch line 11, the second branch line 12, the third branch line 13 and the fourth branch line 14 are electrically connected to connectors 2. Each of the four connectors 2 is detachably connected to the same first connector 3, second connector 4, third connector 5 and sixth connector 6. The second connector 4 and the connectors 2 are fixed together by bolts. The connection method between the first connector 3, the third connector 5 and the sixth connector 6 and the connectors 2 is the same as the connection method between the second connector 4 and the connectors 2.

[0027] The second connector 4 has a mating pin 21 and a terminal block 44. One end of the terminal block 44 is fixedly connected to a pin 42. The second connector 4 has a pin slot 41, and the pin 42 is located in the pin slot 41.

[0028] The terminal 44 is a hollow structure with one end open. An arc-shaped clamping spring 441 is welded on the inner wall of the terminal 44. The arc-shaped clamping spring 441 is used to elastically clamp the connecting pin 21.

[0029] The second connector 4 has a mounting groove 43 communicating with the pin slot 41. The terminal block 44 is fixedly installed in the mounting groove 43. The second connector 4 also has a through hole 45 communicating with the mounting groove 43 and an insertion groove 46 communicating with the mounting groove 43. When the connector 2 is inserted into the insertion groove 46, the connecting pin 21 passes through the through hole 45 and is inserted into the terminal block 44. As can be seen from the above, the first connector 3, the second connector 4, the third connector 5 and the sixth connector 6 can all be detached from the connector 2. At this time, the positions of the first connector 3, the second connector 4, the third connector 5 and the sixth connector 6 can be changed.

[0030] In practical use:

[0031] When the first connector 3 is damaged but the first branch line 11 is not damaged, and the second connector 4 is not damaged but the second branch line 12 is damaged, the second connector 4 can be installed on the first branch line 11 and then it can be used normally.

[0032] When the first connector 3 is undamaged but the first branch line 11 is damaged, and the second connector 4 is damaged but the second branch line 12 is undamaged, the first connector 3 can be installed onto the second branch line 12 for normal use.

[0033] When the third connector 5 is damaged but the third branch line 13 is not damaged, and the fourth connector 6 is not damaged but the fourth branch line 14 is damaged, the fourth connector 6 can be installed on the third branch line 13 and it can be used normally.

[0034] When the third connector 5 is undamaged but the third branch line 13 is damaged, and the fourth connector 6 is damaged but the fourth branch line 14 is undamaged, then the third connector 5 can be installed onto the fourth branch line 14 for normal use.

[0035] Example 2:

[0036] See attached document Figure 4-5 Unlike Embodiment 1, the second connector 4 has a disassembly hole 48, and the outer wall of the connector 2 has an integral elastic locking block 23; at this time, the disassembly and assembly of the first connector 3, the second connector 4, the third connector 5 and the sixth connector 6 with the connector 2 are more convenient.

[0037] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
