Description

Technical Field

[0001] The present invention relates to the technical field of wire harness fixing, and more specifically, to a wire harness centralized fixing device. Background Art

[0002] The reinforcement treatment of the mating part between the conductive end of the wire harness and the terminal is a key link to ensure the stability and safety of electrical connections. Close contact reduces energy loss and avoids local overheating. Under long-term mechanical stress, reinforcement can extend the connection life. Stable contact reduces gap discharge and reduces the fire risk.

[0003] Currently, the reinforcement measure between the conductive end of the wire harness and the terminal is to set a crimping structure at the front end of the conductive end of the wire harness, which only provides ordinary reinforcement functions. It cannot provide real-time warning during wire harness pulling, and cannot give an alarm when the wire harness falls off. True reinforcement is to reduce the risk of wire harness falling off and have an alarm for falling off. The loosening and pulling of the wire harness are all incentives for wire harness falling off, and a monitoring structure needs to be designed for warning, so as to facilitate subsequent troubleshooting and repair. Therefore, we propose a wire harness centralized fixing device. Summary of the Invention

[0004] In view of the above technical problems in the related art, the present invention provides a wire harness centralized fixing device that can solve the above problems.

[0005] To achieve the above technical objectives, the technical solution of the present invention is realized as follows: A wire harness centralized fixing device includes a T-slot base, a U-shaped frame slidably arranged above the T-slot base. At the bottom of the inner wall of the U-shaped frame, an arc-shaped clamp seat A is fixedly arranged. At the top of the inner wall of the U-shaped frame, an arc-shaped clamp seat B is inlaid and slidably arranged. At the top of the U-shaped frame, a cover is fixedly arranged by bolts, and a screw rod is threadedly connected to the middle of the cover. At the bottom end of the outside of the U-shaped frame, a slider base that is inlaid and slidably matched with the T-slot base is fixedly arranged. Trigger rods are fixedly arranged on the front and rear end faces of the slider base. Covers are fixedly arranged at both the front and rear ends of the T-slot base by bolts. A pressing pressure sensor is fixedly arranged in the middle of the cover. A spring is fixedly arranged in the middle of the cover. The pressing pressure sensor is located at the center of the spring and does not contact the spring. The trigger rod is sleeved inside the spring. The pressing pressure sensor is electrically connected to an alarm controller through a data line.

[0006] Further, the arc-shaped clamp seat B and the arc-shaped clamp seat A are symmetrically arranged up and down, and rubber gasket rings are fixedly arranged at the central positions of the arc-shaped clamp seat B and the arc-shaped clamp seat A.

[0007] Further, a photoelectric proximity sensor is fixedly arranged in the middle of the arc-shaped clamp seat A, and the photoelectric proximity sensor is electrically connected to the alarm controller through a data line.

[0008] Further, the top of the photoelectric proximity sensor is 4 mm to 6 mm lower than the top plane of the rubber gasket ring of the arc-shaped clamp seat A.

[0009] Further, pin cylinders are fixedly arranged on both sides of the top of the screw rod, and a rotating semi-ring is hingedly arranged at the top of the screw rod. Both ends of the rotating semi-ring are hinged to the two pin cylinders through shaft pins.

[0010] Further, a rubber sleeve is fixedly arranged on the central surface of the top of the arc-shaped clamp seat B, and the bottom end of the screw rod is sleeved and assembled with the rubber sleeve.

[0011] Further, sliders are fixedly arranged at both ends of the arc-shaped clamp seat B, and sliding grooves for inlaying and matching with the sliders are vertically arranged on both sides of the inner wall of the U-shaped frame.

[0013] Further, one end of the spring is fixed to the surface of the cover plate, and the other end is in contact with the end face of the slider base.

[0014] The beneficial effects of the present invention: The screw rod of the device in this application pushes the arc-shaped clamp seat B close to the arc-shaped clamp seat A, thereby clamping and fixing one end of the wire harness. A photoelectric proximity sensor is set to monitor whether the wire harness is still on the arc-shaped clamp seat, realizing the function of falling-off alarm. When the wire harness receives a pulling force, the trigger rod continuously generates pressure on the pressing pressure sensor, realizing the function of pulling alarm.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art shall fall within the protection scope of the present invention.

[0020] As Figures 1-3 shown, according to the present invention, a wire harness centralized fixing device is disclosed, including a T-slot base 1, a U-shaped frame 3 slidably arranged above the T-slot base 1. An arc-shaped clamp seat A 7 is fixedly arranged at the bottom of the inner wall of the U-shaped frame 3, and an arc-shaped clamp seat B 6 is inlaid and slidably arranged at the top of the inner wall of the U-shaped frame 3. A cover 4 is fixedly arranged at the top end of the U-shaped frame 3 through bolts. A screw 5 is threadedly connected to the middle of the cover 4. A rubber sleeve is fixedly arranged on the central surface of the top of the arc-shaped clamp seat B 6, and the bottom end of the screw 5 is sleeved and assembled with the rubber sleeve; A slide block base 2 that is inlaid and slidably matched with the T-slot base 1 is fixedly arranged at the bottom end of the outside of the U-shaped frame 3. Trigger rods 13 are fixedly arranged on the front and rear end faces of the slide block base 2. Cover plates 10 are fixedly arranged at both the front and rear ends of the T-slot base 1 through bolts. A press-type pressure sensor 11 is fixedly arranged in the middle of the cover plate 10. A spring 12 is fixedly arranged in the middle of the cover plate 10. The press-type pressure sensor 11 is located at the center of the spring 12 and does not contact the spring 12. The trigger rod 13 is sleeved inside the spring 12; Sliding blocks 601 are fixedly arranged at both ends of the arc-shaped clamp seat B 6, and sliding grooves 301 that are inlaid and matched with the sliding blocks 601 are vertically opened on both sides of the inner wall of the U-shaped frame 3; The press-type pressure sensor 11 is electrically connected to the alarm controller through a data line; A photoelectric proximity sensor 9 is fixedly arranged in the middle of the arc-shaped clamp seat A 7, and the photoelectric proximity sensor 9 is electrically connected to the alarm controller through a data line.

[0021] Embodiment 1: The whole device is made of PC material, and the screw is a nylon screw. First, the arc-shaped clamp seat B 6 is installed, and then the cover 4 is covered and the cover 4 is fastened to the U-shaped frame 3 with nylon bolts. After the screw 5 is threadedly matched with the cover 4, the bottom end of the screw 5 is sleeved with the rubber sleeve at the top end of the arc-shaped clamp seat B 6. The sliding blocks 601 at both ends of the arc-shaped clamp seat B 6 are restricted in the sliding grooves 301, so as to realize rotating the screw 5, and the screw 5 pushes the arc-shaped clamp seat B 6 to vertically adjust the position; The slider base 2 is inserted into the T-shaped chute of the T-slot base 1. The trigger rods 13 at both ends of the slider base 2 are sleeved and cooperated with the springs 12. Finally, the cover plate 10 is fixed at the front and rear ends of the T-slot base 1. One end of the spring 12 is in close contact with the end face of the slider base 2. In the initial state, the spring 12 is in a compressed state, and the trigger rod 13 is 1 mm away from the pressing pressure sensor 11. The photoelectric proximity sensor 9 is used to monitor whether the wire harness is located on the arc clamp base A7. When the arc clamp base B6 cooperates with the arc clamp base A7 to clamp and restrain the wire harness end, at this time, the photoelectric proximity sensor 9 can monitor the wire harness, so that the alarm controller does not give an alarm. When the wire harness detaches from the arc clamp base A7, the photoelectric proximity sensor 9 cannot monitor the wire harness, and the alarm controller receives the electrical signal of the photoelectric proximity sensor 9, thereby running the set program to turn on the wire harness detachment alarm light for prompt. When the wire harness is pulled, the pulling force will be transmitted between the trigger rod 13 and the pressing pressure sensor 11. Thus, the pressing pressure sensor 11 will generate an electrical signal with a corresponding value. It is set that when the pulling force is greater than 10 N, the alarm controller processes the electrical signal of the pressing pressure sensor 11, thereby running the set program to turn on the wire harness pulling alarm light for prompt.

[0022] In the preferred technical solution, the arc clamp base B6 and the arc clamp base A7 are symmetrically arranged up and down. Rubber gasket rings 8 are fixedly arranged at the central positions of the arc clamp base B6 and the arc clamp base A7. The rubber gasket rings 8 can be in full contact and fit with the wire harness, which can not only protect the wire harness skin, but also improve the contact friction force and enhance the stability.

[0023] In the preferred technical solution, the top of the photoelectric proximity sensor 9 is 4 mm to 6 mm lower than the top plane of the rubber gasket ring 8 of the arc clamp base A7. The protruding rubber gasket ring 8 can protect the detection head of the photoelectric proximity sensor 9.

[0024] In the preferred technical solution, pin cylinders are fixedly arranged on both sides of the top of the screw rod 5. A rotating half-ring 501 is hinged to the top of the screw rod 5. Both ends of the rotating half-ring 501 are hinged to the two pin cylinders through shaft pins. When the rotating half-ring 501 is lifted to the vertical state, it is convenient to rotate the screw rod 5 through the rotating half-ring 501 without the aid of tools. When not in use, the rotating half-ring 501 fits on the top of the screw rod 5 and will not accidentally touch and rotate the screw rod 5.

[0025] In the preferred technical solution, both the front and rear ends of the slider base 2 protrude 15 mm to 20 mm more than the front and rear ends of the U-shaped frame 3. The overall length of the slider base 2 is larger than the length of the front and rear ends of the U-shaped frame 3, which can slightly improve the support of the slider base 2 for the U-shaped frame 3.

[0026] In a preferred technical solution, one end of the spring 12 is fixed to the surface of the cover plate 10, and the other end is in contact with the end face of the slider base 2. The spring 12 is in contact with the end faces of the cover plate 10 and the slider base 2, and can perform elastic reset when the slider base 2 moves slightly.

[0027] During specific use, pass the wire harness through the arc-shaped clamp seat B6 and the arc-shaped clamp seat A7. After connecting the conductive end of the wire harness to the terminal, reserve a wire harness buffer section for buffer pulling after the wire harness passes through the arc-shaped clamp seat A7, that is, bend a certain arc between the wire harness passing through the arc-shaped clamp seat A7 and the conductive end of the wire harness to avoid the direct influence of pulling the wire harness on the conductive end of the wire harness and the terminal. Rotate the screw 5, and the screw 5 pushes the arc-shaped clamp seat B6 to vertically adjust its position to press and clamp the wire harness skin. The photoelectric proximity sensor 9 can monitor the wire harness, and the alarm controller does not give an alarm. When the pulling force detected by the pressure sensor 11 is less than 10N, the alarm controller does not give an alarm. When the pulling force is greater than 10N, the alarm controller receives the electrical signal of the pressure sensor 11 and thus runs the set program to turn on the wire harness pulling alarm light for prompting. When the wire harness detaches from the arc-shaped clamp seat A7, the photoelectric proximity sensor 9 cannot monitor the wire harness, and the alarm controller receives the electrical signal of the photoelectric proximity sensor 9 and thus runs the set program to turn on the wire harness detachment alarm light for prompting.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
