Description

Technical Field

[0001] This utility model relates to the technical field of automotive air conditioning wiring harnesses, and in particular to a modular automotive air conditioning wiring harness quick-installation structure. Background Technology

[0002] Automotive wiring harnesses are the main network of a car's electrical system; without wiring harnesses, there would be no automotive electrical system. A wiring harness is an assembly consisting of copper contact terminals crimped to wires and cables, then covered with a plastic insulator or an outer metal shell, and bundled together to form a circuit connection. There are many types of automotive wiring harnesses, and the automotive air conditioning wiring harness is one of them. Automotive air conditioning wiring harnesses are generally fixedly arranged on the car's air conditioning housing.

[0003] In existing technology, automotive air conditioning wiring harnesses mainly consist of a main connector and several branch connectors. The branch connectors are relatively small and are therefore secured primarily by plastic clips. Disassembly is achieved by pressing the plastic clips. The main connector, however, is larger than the branch connectors. After inserting the main connector into the corresponding position, it has a central fastening screw. Because the connection between the connector and the interface is only a clip, it is prone to detachment due to road bumps. Therefore, existing technology uses a central fastening screw for fixation. However, after the components are manufactured and assembled in the vehicle, the internal space is limited. Therefore, if a problem occurs with the air conditioning wiring and requires repair and disconnection, removing the screw becomes inconvenient, hindering the repair and maintenance of the air conditioning wiring. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a modular automotive air conditioning wiring harness quick installation structure in order to solve the technical problems mentioned in the background.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A modular automotive air conditioning wiring harness quick-installation structure includes a main line and branch lines. The end of the main line connector is connected to a positioning block. A groove is provided on the top side of the positioning block. Two terminals are connected to the center of the top side of the groove. The end of the main line is connected to the terminals. A locking element is provided in the gap in the middle of the main line head.

[0007] The locking component includes a concave hole, a toothed rod, a positioning screw, and a toothed ring. The concave hole is located at the center of the inner bottom sidewall of the groove and between the two terminals. The toothed rod is slidably installed in the concave hole, and its top end extends upward to the outside of the groove. The positioning screw is fixedly installed on the top of the toothed rod. The toothed ring is located between the two terminals and is rotatably installed on the top side of the inner sidewall of the groove. A driving component is provided on the top of the toothed ring.

[0008] In a preferred embodiment, the present invention can be further configured such that: the driving component includes a winding rod, the winding rod is fixedly installed on the top side of the toothed ring, a steel wire is wound on the winding rod, the steel wire passes through the side of the groove and extends to the side of the positioning block corresponding to the side of the positioning block, and a limiting member is provided on the outside of the positioning block at the end of the steel wire.

[0009] In a preferred embodiment, the present invention can be further configured as follows: the limiting member includes a limiting block, the limiting block is fixedly installed on the side of the limiting block, a positioning post is connected to the top side of the limiting block, a limiting groove is opened on the outer periphery of the positioning post, a limiting ring is connected to the end of the steel wire, the limiting ring is sleeved on the positioning post, and the inner periphery of the limiting ring is inserted into the limiting groove.

[0010] In a preferred embodiment, the present invention can be further configured such that two rotating wheels are rotatably mounted on the side of the positioning block, and the outer periphery of the rotating wheels is in contact with the steel wire.

[0011] In a preferred embodiment, the present invention can be further configured such that: a narrow hole is provided on the bottom sidewall of the groove, a torsion spring is connected to the bottom sidewall of the narrow hole, and the top end of the torsion spring is connected to the toothed ring.

[0012] In a preferred embodiment, the present invention can be further configured such that a baffle is connected to the inner wall of the groove, and the inner circumferential side of the baffle is in contact with the wiring terminal.

[0013] In summary, this utility model has at least one of the following beneficial technical effects:

[0014] 1. This modular automotive air conditioning wiring harness quick-installation structure allows for quick installation and removal of the wiring harness. When using it, the positioning block and terminal block at the end of the main wire are inserted into the terminal wiring hole on the vehicle. Pulling the steel wire causes the positioning screw to rotate, achieving a quick locking and limiting effect. Simultaneously, during disassembly, the limiting ring at the end of the steel wire is released, achieving automatic unlocking. This allows for quick installation and one-click removal of the automotive air conditioning wiring harness, avoiding the impact of limited installation space on disassembly.

[0015] 2. This modular automotive air conditioning wiring harness quick-installation structure, after the steel wire is pulled, will drive the toothed rod to rotate through the toothed ring, thereby quickly driving the positioning screw to connect with the screw hole in the terminal wiring hole, achieving the effect of quick installation;

[0016] 3. This modular automotive air conditioning wiring harness quick-installation structure features a limiting block for installing a positioning post. After the steel wire is pulled out, the positioning screw will connect with the screw hole in the terminal wiring hole. At this point, the steel wire has been pulled out. Then, the steel wire is pulled around the outer periphery of the positioning block to the positioning post, and then the limiting ring is placed on the positioning post, with the inner periphery of the positioning ring inserted into the limiting groove. This achieves the effect of limiting the ring and the steel wire, preventing the steel wire from retracting due to external vibration, which would affect the installation of the automotive air conditioning wiring harness.

[0017] 4. In this modular automotive air conditioning wiring harness quick-installation structure, the outer periphery of the two rotating wheels is in contact with the steel wire, so that the steel wire can be in contact with the rotating wheels when it is pulled out, avoiding the increase in steel wire wear when the steel wire rubs against the positioning block, thereby reducing the service life of the steel wire itself;

[0018] 5. The modular automotive air conditioning wiring harness quick-installation structure has a baffle that limits the sidewall of the terminal wiring hole, preventing the sidewall of the terminal wiring hole from contacting the steel wire, which would affect the extraction of the steel wire. At the same time, it increases the friction on the steel wire, thereby affecting the service life of the steel wire. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0026] Reference Figures 1-4 The modular automotive air conditioning wiring harness quick installation structure disclosed in this utility model includes a main line 1 and a branch line 2. The end of the connector of the main line 1 is connected to a positioning block 3. A groove 4 is provided on the top side of the positioning block 3. Two terminals 5 are connected to the middle of the top side of the groove 4. The end of the main line 1 is connected to the terminals 5. A locking piece 6 is provided in the gap in the middle of the head of the main line 1.

[0027] The locking component 6 includes a concave hole 7, a toothed rod 8, a positioning screw 9, and a toothed ring 10. The concave hole 7 is located at the center of the inner bottom sidewall of the groove 4 and is situated between the two terminals 5. The toothed rod 8 is slidably mounted within the concave hole 7, with its top end extending upward to the outer side of the groove 4. The positioning screw 9 is fixedly mounted on the top of the toothed rod 8. The toothed ring 10 is positioned between the two terminals 5 and is rotatably mounted on the top side of the inner sidewall of the groove 4. A driving component 11 is provided on the top of the toothed ring 10.

[0028] In this embodiment, during use, the positioning block 3 at the end of the main line 1 is inserted into the corresponding connector, and the gap between the terminal 5 and the inner wall of the groove 4 is engaged with the side wall of the terminal wiring hole at the connector. Then, the drive member 11 is pulled, and the drive member 11 drives the toothed ring 10 to rotate. When the toothed ring 10 rotates, it will drive the toothed rod 8 to rotate. The toothed rod 8 will drive the positioning screw 9 to rotate. When the positioning screw 9 rotates, it will gradually insert into the screw hole in the terminal wiring hole, thereby achieving the effect of fixing.

[0029] The toothed ring 10 drives the positioning screw 9 to rotate, and when the positioning screw 9 is threadedly connected to the screw hole in the terminal wiring hole, the positioning screw 9 gradually moves towards the terminal wiring hole, while the toothed rod 8 slides while rotating in the concave hole 7.

[0030] Therefore, when the gear ring 10 rotates, it drives the gear rod 8 to rotate. At the same time, the rotation of the gear rod 8 causes the positioning screw rod 9 to be threadedly connected to the pre-set screw hole in the terminal wiring hole, and the gear rod 8 will also be pulled out. In addition, the pre-set screw hole and the positioning screw rod 9 are threadedly connected to achieve the effect of fixing the positioning block 3, thereby achieving the effect of quick installation of the automotive air conditioning wiring harness.

[0031] In a further preferred embodiment of this utility model, such as Figure 2-4 As shown, the driving component 11 includes a winding rod 12, which is fixedly installed on the top side of the toothed ring 10. A steel wire 13 is wound on the winding rod 12. The steel wire 13 passes through the side of the groove 4 and extends to the side of the positioning block 3. A limiting member 14 is provided on the outside of the positioning block 3 at the end of the steel wire 13.

[0032] In this embodiment, a steel wire 13 is sleeved on the winding rod 12. One end of the steel wire 13 is connected to the winding rod 12, and the other end extends out of the outer side of the positioning block 3. Thus, when the steel wire 13 is pulled, the winding rod 12 will be rotated. When the winding rod 12 rotates, the toothed ring 10 will be rotated.

[0033] Therefore, after the steel wire 13 is pulled, it will drive the toothed rod 8 to rotate through the toothed ring 10, which will then quickly drive the positioning screw 9 to connect with the screw hole in the terminal wiring hole, thus achieving the effect of rapid installation.

[0034] In a further preferred embodiment of this utility model, such as Figure 2-4 As shown, the limiting member 14 includes a limiting block 15, the limiting block 15 is fixedly installed on the side of the limiting block 15, the top side of the limiting block 15 is connected to a positioning post 16, the outer peripheral side of the positioning post 16 is provided with a limiting groove 17, the end of the steel wire 13 is connected to a limiting ring 18, the limiting ring 18 is sleeved on the positioning post 16, and the inner peripheral side of the limiting ring 18 is inserted into the limiting groove 17.

[0035] In this embodiment, the limiting block 15 is used to install the positioning post 16. After the steel wire 13 is pulled out, the positioning screw 9 will be threadedly connected to the screw hole in the terminal wiring hole. At this time, the steel wire 13 has been pulled out. Then, the steel wire 13 is pulled around the outer periphery of the positioning block 3 to the positioning post 16. Then, the limiting ring 18 is put on the positioning post 16, and the inner periphery of the positioning ring is inserted into the limiting groove 17, thereby achieving the effect of the limiting ring 18 and the steel wire 13, preventing the steel wire 13 from retracting due to external vibration, which would affect the installation of the automotive air conditioning wiring harness.

[0036] In a further preferred embodiment of this utility model, such as Figure 2-4As shown, two rotating wheels 19 are rotatably mounted on the side of the positioning block 3, and the outer periphery of the rotating wheels 19 is in contact with the steel wire 13.

[0037] In this embodiment, the outer periphery of the two rotating wheels 19 is in contact with the steel wire 13, so that the steel wire 13 can be in contact with the rotating wheels 19 when it is pulled out, thus avoiding the increase of wear on the steel wire 13 when it rubs against the positioning block 3, thereby reducing the service life of the steel wire 13.

[0038] In a further preferred embodiment of this utility model, such as Figure 2-4 As shown, a narrow hole 20 is provided on the bottom sidewall of the groove 4, and a torsion spring 21 is connected to the bottom sidewall of the narrow hole 20. The top end of the torsion spring 21 is connected to the toothed ring 10.

[0039] In this embodiment, the narrow hole 20 is used to install the torsion spring 21. The top of the torsion spring 21 is connected to the toothed ring 10. Therefore, when the toothed ring 10 rotates, it will drive the torsion spring 21 to rotate, so that the torsion spring 21 is subjected to a certain stress. If it is necessary to disassemble the car air conditioning wiring harness, the limiting ring 18 at the end of the steel wire 13 is removed from the positioning post 16. The reaction force applied by the torsion spring 21 will drive the toothed ring 10 to reverse, thereby driving the winding to rotate, so that the steel wire 13 is retracted. At the same time, it will also drive the toothed rod 8 to rotate, thereby driving the positioning screw 9 to rotate, so that the positioning screw 9 can be taken out from the screw hole in the terminal wiring hole, thereby enabling the car wiring harness to be quickly removed.

[0040] In a further preferred embodiment of this utility model, such as Figure 2 As shown, a baffle 22 is connected to the inner wall of the groove 4, and the inner circumference of the baffle 22 is in contact with the terminal 5.

[0041] In this embodiment, the baffle 22 is provided to limit the side wall of the terminal wiring hole, so as to prevent the side wall of the terminal wiring hole from contacting the steel wire 13, thereby affecting the steel wire 13 from being pulled out. At the same time, it increases the friction force on the steel wire 13, which in turn affects the service life of the steel wire 13.

[0042] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
