[0007] The positioning structure includes a groove, with grooves at both ends of the connecting handle. A movable sleeve is movably connected inside the groove, and a fixed cylinder is fixedly connected to one end inside the groove. Limiting blocks are fixedly connected to the same end on both sides of the fixed cylinder. Limiting grooves are formed on both sides inside the movable sleeve.

[0014] As a further technical solution of this utility model, the rubber sleeve is movably connected to the connecting line, and the rubber frame is movably connected to the connecting line.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the quick-plug modular automotive wiring harness not only achieves quick plugging and unplugging and prevents wire tangling, but also prevents damage at the wire connection points;

[0016] (1) By setting a connecting handle, connecting plate, movable sleeve, positioning block, groove, movable slot, anti-slip strip, spring, fixed cylinder, limit block and limit slot, when installing the wire harness, pressing the movable sleeve at both ends of the connecting handle drives the connecting plate to move. The connecting plate drives the positioning block to retract so that the connector can be inserted into the corresponding socket of the automotive system. After insertion, the movable sleeve is released and the movable sleeve pushes the connecting plate out under the push of the spring. The connecting plate drives the positioning block to insert into the slot set inside the socket, thereby positioning the connector through the connecting plate. When it is necessary to pull out, the movable sleeve at both ends of the connecting handle is pressed to drive the positioning block to disengage from the socket through the connecting plate. Then the connector can be pulled out quickly, realizing quick insertion and removal.

[0017] (2) By setting up a wire clamp sleeve, a plastic sheet, a wire clamping convex plate and a top groove, before installing the wire harness, multiple sets of connecting wires are fed into the wire clamp sleeve through the top groove. The multiple sets of wire clamping convex plates at both ends of the wire clamp sleeve can separate the multiple sets of connecting wires, so that the multiple sets of connecting wires are arranged side by side at equal intervals. In this way, after the wire harness is installed, the wire clamp sleeve can effectively prevent the connecting wires from getting tangled. Also, keeping the connecting wires at a certain distance can prevent the connecting wires from sticking together and affecting heat dissipation. Furthermore, the plastic sheet on one side of the wire clamp sleeve can keep the adjacent wire clamp sleeves at a distance to position the connecting wires as a whole, thus effectively preventing the connecting wires from getting tangled.

[0018] (3) By setting a fixed sleeve, a rubber sleeve, a slot and a rubber frame, a rubber frame is installed inside the fixed sleeve on one side of the wire harness connecting handle. The rubber frame fits against the outside of multiple sets of connecting wires to protect the connecting wires. The rubber sleeve on one side of the rubber frame can support each set of connecting wires respectively. The slots at both ends of the rubber sleeve can increase the degree of deformation, thereby further improving the protection effect on the connecting wires and preventing the connection between the connecting wires and the connecting handle from being damaged due to excessive folding angle. This achieves the goal of preventing the connection of the connecting wires from being damaged due to excessive bending angle. Attached Figure Description

[0024] 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.

[0025] Example: Please refer to Figure 1-4 A quick-plug modular automotive wiring harness includes a connecting wire 1, connecting handles 3 fixedly connected to both sides of the connecting wire 1, a connector 4 fixedly connected to one side of the connecting handle 3, the center line of the connecting handle 3 and the center line of the connector 4 being on the same horizontal plane, and a positioning structure for easy plugging and unplugging being provided inside the connecting handle 3.

[0026] The positioning structure includes a groove 13. Grooves 13 are provided at both ends of the connecting handle 3. A movable sleeve 11 is movably connected inside the groove 13. A fixed cylinder 19 is fixedly connected to one end inside the groove 13. Limiting blocks 20 are fixedly connected to the same end on both sides of the fixed cylinder 19. Limiting grooves 21 are provided on both sides inside the movable sleeve 11. A spring 18 is fixedly connected to one end inside the fixed cylinder 19. A connecting plate 5 is fixedly connected to one side of the movable sleeve 11. A positioning block 12 is fixedly connected to one side of one end of the connecting plate 5. A movable groove 14 is provided on the same side at both ends of the connecting handle 3. An anti-slip strip 15 is fixedly connected to one end of the movable sleeve 11.

[0027] The interior of the movable groove 14 is connected to the interior of the recess 13, and the fixed cylinder 19 is movably connected to the movable sleeve 11.

[0028] The limiting block 20 is slidably connected to the limiting groove 21, and the spring 18 is fixedly connected to the movable sleeve 11;

[0029] The connecting plate 5 is movably connected to the movable groove 14, and the center line of the movable sleeve 11 and the center line of the fixed sleeve 19 are on the same vertical plane.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, when installing the wiring harness, pressing the movable sleeves 11 at both ends of the connecting handle 3 causes the connecting plate 5 to move. The connecting plate 5 causes the positioning block 12 to retract so that the connector 4 can be inserted into the corresponding socket of the automotive system. After insertion, releasing the movable sleeves 11 pushes the connecting plate 5 out under the push of the spring 18. The connecting plate 5 causes the positioning block 12 to be inserted into the slot set inside the socket, thereby positioning the connector 4 through the connecting plate 5. When it is necessary to pull out, pressing the movable sleeves 11 at both ends of the connecting handle 3 causes the positioning block 12 to disengage from the socket through the connecting plate 5, and then the connector 4 can be quickly pulled out, realizing quick insertion and removal.

[0031] The external of the connecting wire 1 is movably connected to a wire fixing sleeve 2. The two ends of the wire fixing sleeve 2 are fixedly connected to wire fixing protrusions 16. The top of the wire fixing sleeve 2 is provided with a top groove 17. A plastic piece 8 is fixedly connected to the front end of one side of the wire fixing sleeve 2.

[0032] The wire fixing protrusion 16 is movably connected to the connecting wire 1, and the wire fixing protrusions 16 at both ends inside the wire fixing sleeve 2 are arranged at equal intervals.

[0033] Specifically, such as Figure 1 and Figure 3 As shown, before installing the wire harness, multiple sets of connecting wires 1 are fed into the wire clamp 2 through the top groove 17. Multiple sets of wire clamping protrusions 16 at both ends of the wire clamp 2 can separate the multiple sets of connecting wires 1, so that the multiple sets of connecting wires 1 are arranged side by side at equal intervals. In this way, after the wire harness is installed, the wire clamp 2 can effectively prevent the connecting wires 1 from getting tangled. The connection of the connecting wires 1 is also kept at a certain distance to prevent the connecting wires 1 from sticking together and affecting heat dissipation. In addition, the plastic piece 8 on one side of the wire clamp 2 can keep the adjacent wire clamps 2 at a distance to position the connecting wires 1 as a whole, which can effectively prevent the connecting wires 1 from getting tangled.

[0034] A fixed sleeve 6 is fixedly connected to one side of the connecting handle 3. A rubber frame 10 is fixedly connected inside the fixed sleeve 6. A rubber sleeve 7 is fixedly connected to one side of the rubber frame 10. The rubber sleeve 7 has slots 9 at both ends.

[0035] The rubber sleeve 7 is movably connected to the connecting line 1, and the rubber frame 10 is movably connected to the connecting line 1;

[0036] Specifically, such as Figure 1 As shown, a rubber frame 10 is installed inside the fixing sleeve 6 on one side of the wire harness connecting handle 3. The rubber frame 10 fits against the outside of multiple sets of connecting wires 1 to protect the connecting wires 1. The rubber sleeve 7 on one side of the rubber frame 10 can support each set of connecting wires 1. The slots 9 at both ends of the rubber sleeve 7 can increase the degree of deformation, thereby further improving the protection effect on the connecting wires 1 and preventing damage caused by excessive bending angle at the connection between the connecting wires 1 and the connecting handle 3. This achieves the goal of preventing damage caused by excessive bending angle at the connection of the connecting wires 1.

[0037] Working Principle: In use, multiple sets of connecting wires 1 are fed into the wire-fixing sleeve 2 through the top groove 17. Multiple sets of wire-fixing protrusions 16 at both ends of the wire-fixing sleeve 2 separate the multiple sets of connecting wires 1, allowing them to be arranged side-by-side at equal intervals. This effectively prevents the connecting wires 1 from tangling after installation, and the spacing between the connecting wires prevents them from sticking together and affecting heat dissipation. Furthermore, the plastic sheet 8 on one side of the wire-fixing sleeve 2 maintains the spacing between adjacent sleeves, positioning the connecting wires 1 as a whole. When installing the wire harness, pressing the movable sleeves 11 at both ends of the connecting handle 3 moves the connecting plate 5, causing the positioning block 12 to retract, facilitating the insertion of the connector 4 into the corresponding socket of the automotive system. After insertion, releasing the movable sleeves 11 triggers the spring 1... Driven by 8, the movable sleeve 11 pushes out the connecting plate 5. The connecting plate 5 drives the positioning block 12 to insert into the slot inside the socket, thereby positioning the connector 4 through the connecting plate 5. When it is necessary to pull out, the movable sleeve 11 at both ends of the connecting handle 3 is pressed, and the positioning block 12 is driven out of the socket by the connecting plate 5. Then the connector 4 can be pulled out quickly. A rubber frame 10 is installed inside the fixed sleeve 6 on one side of the wire harness connecting handle 3. The rubber frame 10 fits against the outside of multiple sets of connecting wires 1 to protect the connecting wires 1. The rubber sleeve 7 on one side of the rubber frame 10 can support each set of connecting wires 1 respectively. The slots 9 at both ends of the rubber sleeve 7 can increase the degree of deformation, thereby further improving the protection effect on the connecting wires 1 and preventing damage caused by excessive folding angle at the connection between the connecting wires 1 and the connecting handle 3.
