Technical Field

[0001] The present invention relates to the technical field related to multi-core wire harness connectors, and in particular to an automatic centering guide mechanism for a multi-core wire harness connector and a use method thereof. Background Art

[0002] A multi-core wire harness connector is a device used to connect multiple wires or cables. It is mainly composed of multiple bundles of wire cores and connecting connectors. It plays an important role in various industries, providing reliable electrical connections and signal transmission for equipment and systems, and realizing efficient interaction of data and power.

[0003] The current multi-core wiring harness connector has limited docking space when the wiring harness needs to be installed in a small space inside a car. This leads to limited docking space for the connector and may also cause the wiring harness to be misplugged, which reduces the installation convenience of the multi-core wiring harness connector. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an automatic centering guide mechanism for a multi-core wire harness connector.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A multi-core wiring harness connector automatic centering guide mechanism includes a mounting plate, the upper surface of the mounting plate is fixedly connected to a horizontal plate, the outer wall of the horizontal plate is fixedly connected to a bracket, the surface of the bracket is rotatably connected to a knob via a bearing, the lower end of the knob is fixedly connected to a cam, the outer wall of the cam contacts two square rods, the surfaces of the two square rods are respectively fixedly connected to the two ends of a spring, a sliding groove is provided on the surface of the horizontal plate, the sliding groove is slidably connected to the two square rods, and the protruding parts at the lower ends of the two square rods are respectively fixedly connected to the corresponding guide plates.

[0006] Preferably, the inner surfaces of the two guide plates are processed into an inclined shape.

[0007] Preferably, the outer wall of the mounting plate is fixedly connected to the multi-core wiring harness connector.

[0008] Preferably, the bracket is threadedly connected to the locking bolt, and the surface of the locking bolt is tightly pressed against the knob.

[0009] Preferably, the lower end of the knob is rotatably connected to the transverse plate via a bearing.

[0010] Preferably, two mounting holes are processed on the surface of the mounting plate.

[0011] Preferably, the protruding parts of the two square rods are movable through the transverse plate via sliding grooves.

[0012] A centering and guiding method based on an automatic centering and guiding mechanism of a multi-core wiring harness connector comprises the following steps: S1. Place the multi-core wire harness to be connected between two guide plates (10); S2. Release the locked state of the knob (5): Loosen or remove the locking bolt (7) threadedly connected to the bracket (4) so ​​that the knob (5) can rotate freely; S3. Turning the knob (5) drives the cam (6) to rotate, and using the outer contour of the cam (6) to push the two square rods (8) to slide toward each other along the slide groove (9) of the horizontal plate (3), while compressing the spring (11) connecting the two square rods (8); S4. The two guide plates (10) are driven to move synchronously toward the center by the protruding portion at the lower end of the square rod (8) until the inclined inner surface thereof clamps the wire harness and realizes automatic centering; when the inclined inner surface of the guide plate (10) contacts the wire harness, the wire harness slides along the inclined surface to the center position and gathers; S5. Tighten the locking bolt (7) against the knob (5) to fix the rotation angle of the cam (6) to lock the position of the guide plate (10); S6. Insert the aligned wire harness into the multi-core wire harness connector (1) to complete the plugging operation.

[0013] In step S3, the spring (11) continuously applies pressure to the square rod (8) directed toward the cam (6), ensuring that the square rod (8) always maintains contact with the outer wall of the cam (6); the sliding direction of the square rod (8) is constrained by the trajectory of the slide groove (9), so that the guide plate (10) can only move in the horizontal direction.

[0014] The beneficial effects of the present invention are: 1. Through the provided mounting plate, cross plate, bracket, knob, cam, square rod, guide plate and spring, when the multi-core wiring harness connector needs to be centered, the operator first places the wiring harness between the two guide plates, and then the operator removes the locking bolt and turns the knob, which drives the cam to rotate. Due to the spring, the two square rods are always close to the cam. When the cam rotates, the two square rods drive the guide plates below to approach each other. After the two guide plates center the wiring harness, the operator stops turning the knob and fixes it with the locking bolt, thereby fixing the angle of the cam to prevent the guide plates from moving. The above method can make the wiring harness centered at the multi-core wiring harness connector, thereby facilitating the operator to plug and unplug the wiring harness, thereby improving the installation convenience of the multi-core wiring harness connector. 2. By setting the guide plate, since the surface of the guide plate is set obliquely, the wire harness gradually gathers toward the middle when the guide plate comes into contact, which improves the working effect of the centering guide mechanism.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1, reference Figures 1 to 5The cam 6 is fixedly connected to the upper end of the cam 6 and the lower end of the cam 6 is fixedly connected to the lower end of the cam 6. The cam 6 drives the cam 6 to rotate. The outer wall of the cam 6 contacts the two square rods 8, and the cam 6 drives the two square rods 8 to move. The surfaces of the two square rods 8 are respectively fixedly connected to the two ends of the spring 11. The spring 11 makes the two square rods 8 always close to the cam 6. The surface of the cross plate 3 is provided with a slide groove 9, which is slidably connected to the two square rods 8. The square rod 8 moves on the slide groove 9. The protruding parts of the lower ends of the two square rods 8 are respectively fixedly connected to the corresponding guide plates 10, and the square rod 8 drives the guide plate 10 to move. When the multi-core wiring harness connector 1 needs to be centered, the operator first places the wiring harness between the two guide plates 10, then the operator removes the locking bolt 7, and then turns the knob 5, which drives the cam 6 to rotate. Due to the spring 11, the two square rods 8 are always close to the cam 6. When the cam 6 rotates, the two square rods 8 will drive the guide plates 10 below to approach each other. When the two guide plates 10 center the wiring harness, the operator stops turning the knob 5 and fixes it with the locking bolt 7, thereby fixing the angle of the cam 6 to prevent the guide plates 10 from moving. The above method can make the wiring harness centered at the multi-core wiring harness connector 1, thereby facilitating the operator to plug and unplug the wiring harness, thereby improving the installation convenience of the multi-core wiring harness connector 1.

[0019] In this embodiment, the inner surfaces of the two guide plates 10 are processed into an inclined shape. The inclined setting allows the wiring harness to be centered and gathered more quickly. The outer wall of the mounting plate 2 is fixedly connected to the multi-core wiring harness connector 1, and the bracket 4 is threadedly connected to the locking bolt 7. The surface of the locking bolt 7 is tightly pressed against the knob 5. The locking bolt 7 locks the angle of the knob 5 to prevent the knob 5 from driving the cam 6 to change its angle. The lower end of the knob 5 is rotatably connected to the cross plate 3 through a bearing, and the knob 5 rotates on the cross plate 3. Two mounting holes 12 are processed on the surface of the mounting plate 2. The mounting holes 12 facilitate the operator to install the mounting plate 2 to the desired position. The protruding parts of the two square rods 8 are movable through the cross plate 3 through the slide groove 9.

[0020] The working principle of this embodiment: when in use, the operator first places the wiring harness between the two guide plates 10, then the operator removes the locking bolt 7, and then turns the knob 5, the knob 5 drives the cam 6 to rotate, and the spring 11 makes the two square rods 8 always close to the cam 6. When the cam 6 rotates, the two square rods 8 will drive the guide plates 10 below to approach each other. At the same time, since the protruding part of the square rod 8 is stuck in the slide groove 9, the square rod 8 can only move along the slide groove 9 when it moves. When the two guide plates 10 center the wiring harness, the operator stops turning the knob 5 and fixes it with the locking bolt 7, thereby fixing the angle of the cam 6 to prevent the guide plate 10 from moving. At the same time, due to the inclined processing of the guide plate 10, the wiring harness can be centered and gathered more quickly when it contacts the guide plate 10, which facilitates the operator to plug and unplug the wiring harness connector.

[0021] The present invention also relates to a centering and guiding method based on an automatic centering and guiding mechanism of a multi-core wiring harness connector, comprising the following steps: S1. The multi-core wiring harness to be connected is placed between the two guide plates 10; S2. Release the locked state of the knob 5: Loosen or remove the locking bolt 7 threadedly connected to the bracket 4 so that the knob 5 can rotate freely; S3. Turning the knob 5 drives the cam 6 to rotate, using the outer contour of the cam 6 to push the two square rods 8 along the chute 9 of the horizontal plate 3 to slide toward each other, while compressing the spring 11 connecting the two square rods 8; S4. The protrusions at the lower ends of the square rods 8 drive the two guide plates 10 to move synchronously toward the center until their inclined inner surfaces grip the harness and achieve automatic centering. When the inclined inner surfaces of the guide plates 10 come into contact with the harness, the harness slides along the inclined surfaces to the center and converges. S5. Tighten the locking bolt 7 against the knob 5, fixing the rotation angle of the cam 6 to lock the position of the guide plate 10; S6. Insert the aligned wire harness into multi-core wire harness connector 1 to complete the plugging operation.

[0022] In step S3, the spring 11 continuously applies pressure to the square rod 8 directed toward the cam 6, ensuring that the square rod 8 always maintains contact with the outer wall of the cam 6; the sliding direction of the square rod 8 is constrained by the trajectory of the slide groove 9, so that the guide plate 10 can only move in the horizontal direction.

[0023] This alignment guide method has the following advantages: Improve centering accuracy: The cam is rotated by the knob, and the outer contour of the cam is used to push the square rods to slide toward each other along the slide groove. At the same time, the spring is compressed, thereby driving the guide plate to move synchronously toward the center. The movement process is stable and controllable, and the wire harness can be accurately adjusted to the center position to achieve high-precision centering, effectively avoiding the deviation problem when the wire harness is plugged in, and improving the connection reliability of the multi-core wire harness connector.

[0024] Easy to operate: Simply place the wire harness between the guide plates, unlock the knob, and turn it to automatically complete the centering process. No complicated operations and adjustments are required, which greatly reduces the operator's operating difficulty and workload, improves work efficiency, and makes it easy to center and connect multi-core wire harness connectors even in a confined space.

[0025] Strong adaptability: The inclined inner surface design of the guide plate enables the wire harness to automatically slide along the inclined surface to the center position when it contacts the guide plate. It is suitable for wire harnesses of different diameters and shapes, has strong versatility and adaptability, and can meet the centering requirements of various multi-core wire harness connectors.

[0026] High stability: The spring continuously applies pressure to the square rod pointing to the cam, ensuring that the square rod always maintains close contact with the outer wall of the cam, ensuring the stability and reliability of the transmission, and enabling the guide plate to move and position stably during the centering process without loosening or offsetting, thereby ensuring the stability of the centering effect.

[0027] Reliable locking: By tightening the locking bolt against the knob, the rotation angle of the cam can be fixed, thereby firmly locking the position of the guide plate to prevent the guide plate from moving or loosening during the plug-in process, ensuring the stable maintenance of the centering state of the wire harness and providing reliable protection for the plug-in of the multi-core wire harness connector.

[0028] Improve installation efficiency: The entire centering and guiding process is fast and efficient, and the centering and plugging operations of the wire harness can be completed in a short time, effectively shortening the installation time of multi-core wire harness connectors and improving production efficiency.

[0029] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
