Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire harness routing detection devices, and particularly relates to a wire harness detector. Background Art
[0002] Many devices are required for the production of wire harnesses, and different devices have different functions. Most of these devices require wires to be routed. During the routing process, if the wires become knotted, the production of the wire harness cannot proceed, and the device has to stop running immediately. Therefore, it is very necessary to promptly detect the knotted cables and the knotting positions and output signals to the device to interrupt the device.
[0003] However, one point that needs to be considered is that during the routing process, when the device detects that the cable is knotted, it is necessary to promptly block the knotted position. However, due to the inertia of the device, the cable often directly passes through the detector, resulting in damage to the detector or the wire.
[0004] Therefore, the applicant adds a damping function on the basis of the original design to reduce the impact load caused by inertia, so as to achieve the effect of protecting the wire harness. Content of the Utility Model
[0005] Therefore, the utility model provides a wire harness detector to solve the problem of wire damage caused by the impact load due to low inertia in the prior art.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] The utility model discloses a wire harness detector, comprising:
[0008] A guide block, with a sensitive resistor installed at the bottom, and a sleeve is movably inserted through the axis of the guide block, and the wire harness is adapted to pass through the sleeve;
[0009] A damping spring, sleeved on the sleeve, and one end of the damping spring is connected to the sleeve and the other end is connected to the guide block;
[0010] A limit fastener, screwed and installed at the end of the guide block and adapted to abut against the sleeve to prevent the sleeve from disengaging from the guide block.
[0011] Further, the guide block includes:
[0012] A damping hole, with the damping spring arranged inside, and the damping hole is arranged at the axis of the block;
[0013] A guide hole, with the end coaxially arranged and communicating with the damping hole, and there is a detection position in the radial direction of the guide hole, and a sensitive resistor is installed in the detection position.
[0014] Further, the sleeve includes a tube body, a retaining ring and a wire routing hole. The tube body is movably inserted into the guiding hole. A retaining ring is integrally provided at the end of the tube body, and the retaining ring is adapted to move within the damping hole.
[0015] The wire routing hole is located on the axis of the tube body and penetrates through the retaining ring.
[0016] Further, a rotary spiral groove is provided on the outer side of the tube body;
[0017] A number of limit pins are circumferentially provided in the guiding hole;
[0018] Wherein, when the tube body expands and contracts, the limit pins are adapted to slide relative to the rotary spiral groove and drive the telescopic tube body to rotate.
[0019] Further, the sensitive resistor is a photoresistor or a force-sensitive resistor.
[0020] Further, the guiding block and the sleeve are made of plastic and are integrally formed by an injection molding process.
[0021] Further, a chamfer is provided at the outer edge of the wire routing hole.
[0022] The present utility model has the following advantages:
[0023] The wire harness detector disclosed by the present utility model can be connected to a wire harness device as a limit switch. Since the knotted wire cannot pass through the sleeve and can only drive the sleeve to move, during the movement of the sleeve, the sensitive resistor is triggered to interrupt the operation of the device. Due to the elastic action of the damping spring, the impact energy caused by the inertia generated by the sudden stop of the device can be effectively absorbed, thereby protecting the cable and the wire harness detector. Moreover, this device also has the advantages of being easy to produce and having a low cost, which is conducive to mass production and popularization in society. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following specific embodiments illustrate the implementation manners of the present utility model. Those familiar with this technology can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0033] Please refer to Figures 1 - 5 together. The present utility model discloses a wire harness detector, which is connected to the PLC of the control device and is used to detect the position where the wire is knotted and send a digital input signal to interrupt the operation of the device to the PLC. The main structure includes a guide block 1, a sensitive resistor 2, a sleeve 3, and a damping spring 4. Among them, the sensitive resistor 2 refers to a resistor whose device characteristics are sensitive to the effects of temperature, humidity, light, gas, magnetic field, pressure, etc., and the sensitive resistor 2 is connected in series to the PLC. When the sleeve 3 moves to trigger the sensitive resistor 2, the resistance value of the sensitive resistor 2 changes, then a digital input signal can be sent to the PLC and the operation of the device can be interrupted.
[0034] In this embodiment, as Figure 1 , the sensitive resistor 2 is installed at the bottom of the guide block 1, and a sleeve 3 is movably inserted through the axis of the guide block 1. The axis position of the sleeve 3 is suitable for passing through the wire harness and can prevent the knotted cable from passing through. In addition, a limit fastener 5 is screwed and installed at the end of the guide block 1, and the end of the limit fastener 5 can abut against the sleeve 3 to prevent the sleeve 3 from disengaging from the guide block 1. Specifically, a damping spring 4 is sleeved on the sleeve 3. One end of the damping spring 4 is connected to the sleeve 3 and the other end is connected to the guide block 1. Thus, the elastic force of the damping spring 4 can produce a damping effect on the sleeve 3, and then relieve the impact load generated by the wire harness on the sleeve 3 due to inertia, and avoid damage or breakage of the wire harness.
[0035] In some embodiments, as Figure 3 , the guide block 1 includes a damping hole 11 and a guide hole 13. The damping spring 4 is arranged in the damping hole 11, and the damping hole 11 is arranged at the axis of the block body 12. The retaining ring 32 of the sleeve 3 slides along the damping hole 11, and the retaining ring 32 abuts against one end of the damping spring 4, while the other end of the damping spring 4 abuts against the guide hole 13. The tube body 31 of the sleeve 3 is slidably inserted into the guide hole 13. Thus, by squeezing the damping spring 4 through the retaining ring 32, the impact load can be fully absorbed and a good protection effect can be achieved.
[0036] In this embodiment, as Figure 3 and Figure 5 , the guide hole 13 is coaxially arranged and communicated with the damping hole 11, and there is a detection position 14 in the radial direction of the guide hole 13. The sensitive resistor 2 is installed in the detection position 14. Among them, the sensitive resistor 2 is preferably a photoresistor or a force-sensitive resistor. When the tube body 31 passes through the guide hole 13, the sensitive resistor 2 can be squeezed or covered, so that the resistance value of the sensitive resistor 2 changes, and then a switching value of the control device is issued.
[0037] In some embodiments, as Figure 4 , the sleeve 3 includes a tube body 31, a retaining ring 32 and a wire routing hole 33. A retaining ring 32 is integrally arranged at the end of the guide hole 13, and the retaining ring 32 is suitable for moving in the damping hole 11. In addition, a wire routing hole 33 is arranged at the axis of the tube body 31, and the wire routing hole 33 penetrates through the retaining ring 32 to guide the wire harness through the sleeve 3. And a chamfer 8 is arranged on the outer edge of the wire routing hole 33, which can avoid scratching when the wire speed passes through the wire routing hole 33 and can also reduce the wear of the tube body 31.
[0038] In this embodiment, the guide block 1 and the sleeve 3 are made of plastic material and are integrally formed by an injection molding process, which can reduce the product cost and facilitate mass production.
[0039] In a specific implementation disclosed in the present utility model, as Figure 2And Figure 4 , a rotary spiral groove 6 is arranged on the outer side of the pipe body 31, and a plurality of limiting pins 7 are circumferentially arranged on the inner circumference of the guiding hole 13. The end part of the limiting pin 7 is embedded into the rotary spiral groove 6. Specifically, when the pipe body 31 expands and contracts, the limiting pin 7 is adapted to slide relatively along the rotary spiral groove 6 and drive the telescopic pipe body 31 to rotate. Thus, the pipe body 31 can perform a screwing-in or screwing-out movement, thereby increasing the total displacement stroke of the pipe body 31 and improving the damping effect generated by the pipe body 31.
[0040] On the basis of this embodiment, both ends of the damping spring 4 can be fixedly connected to the retaining ring 32 and the guiding block 1 respectively through hot melt adhesive. When the pipe body 31 performs a screwing-in movement, the inner diameter of the damping spring 4 narrows and winds around the pipe body 31, thereby generating frictional force with the surface of the pipe body 31, thus further preventing structural damage caused by extreme stress.
[0041] Although the present utility model has been described in detail above with general descriptions and specific embodiments, on the basis of the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
