Description

Technical Field

[0001] This invention relates to the field of spring-loaded wire breakage detectors, and in particular to a waterproof protection and fixing device for the circuit of a spring-loaded wire breakage detector and its usage method. Background Technology

[0002] As a pre-processing equipment for doubling twisters, the main function of a yarn doubling machine is to combine two or more strands of yarn into one strand for easier doubling. During yarn doubling, situations such as yarn breakage or the end of the winding process are inevitable. To avoid problems like single yarns or missing strands during production, a yarn detector is used for inspection; the term "yarn breakage detector" is simply "yarn detector."

[0003] According to Chinese Patent No. CN215713637U, a wire probe is disclosed, including a wire probe housing, one end of which is an open end. A wire probe detection end is provided on the side of the wire probe housing away from the open end. Limiting components are provided on opposite inner walls of the wire probe housing. Each limiting component includes two parallel limiting strips and a number of balance blocks. A PCB board is provided inside the wire probe housing. The two sides of the PCB board are respectively located between the two limiting strips on the inner walls of the two sides of the wire probe housing. A baffle plate is provided on the end of the PCB board near the open end. The side wall of the baffle plate away from the open end abuts against the balance blocks. A wire is provided on the PCB board. A wire hole is opened on the baffle plate. The end of the wire away from the PCB board passes through the wire hole and is located outside the wire probe housing. An adhesive block is provided on the side of the wire probe housing near the open end. As can be seen from the above structure, the circuit part of this texturing yarn breakage detector cannot achieve effective waterproof protection. In the high humidity, oil mist, and daily cleaning environment of the texturing workshop, water vapor and oil can easily penetrate into the interior through cable joints and wire gaps, causing the insulation layer of the circuit to become damp and age, and the terminals to rust and oxidize. This will not only cause faults such as detection signal drift, false alarms, and missed yarn breakage detection, resulting in waste yarn and batches of defective products in texturing production, but also easily cause short circuits, leakage and arcing problems. This will shorten the service life of the detector and supporting control components, greatly increase the frequency of equipment maintenance and operation and maintenance costs, and also pose safety hazards such as electric shock to operators and fire in the workshop. It is difficult to adapt to the complex production environment of the textile workshop with its humid and oily conditions, and the equipment has poor operational stability. Summary of the Invention

[0004] In order to overcome the above-mentioned technical deficiencies, the present invention provides a waterproof protection and fixing device for the circuit of a spring-loaded broken wire detector and its usage method, thereby solving the problems mentioned in the background art.

[0005] This invention discloses a waterproof protection and fixing device for a spring-loaded broken wire detector circuit, comprising a wire detector housing, a wire body at one end of the wire detector housing, and a plug body connected to the other end of the wire body. A protective component is disposed between the plug body and the wire detector housing. The protective component includes a wire fixing seat, one end of which is connected to the wire detector housing, and the other end of which is fixedly connected to a protective base layer. Multiple protective frames are disposed inside the protective base layer, and an installation component is fixedly connected to the other end of the protective base layer. The protective component is interlocked with the plug body through the installation component. The protective base layer includes a protective inner layer disposed outside the protective frames, and a waterproof outer layer is fixedly connected to the outside of the protective inner layer. The protective inner layer is a nylon material layer, and the waterproof outer layer is a polyethylene film layer.

[0006] The installation assembly includes a mounting base, one end of which is fixedly connected to the plug body, and the other end of which is provided with a plug slot. A plug frame is fixedly connected to the end of the protective base layer, and the plug frame and the plug slot are plugged into each other.

[0007] Both sides of the insertion slot are provided with snap-fit ​​holes, and both sides of the insertion frame are provided with grooves. A snap-fit ​​spring is fixedly connected inside the groove, and a snap-fit ​​connector is fixedly connected to the other end of the snap-fit ​​spring. The snap-fit ​​connector and the snap-fit ​​hole snap-fit ​​into each other.

[0008] A connecting sliding hole is provided on the outer wall of the groove. A connecting rod is fixedly connected to the snap connector. An operating plate is fixedly connected to the other end of the connecting rod. The connecting rod extends to the outside of the connecting sliding hole. The operating plate is located outside the plug frame. The connecting rod and the connecting sliding hole are slidably connected to each other.

[0009] The mounting base has a hidden groove on its outer side, and a connecting through hole is provided inside the hidden groove. A connecting screw is inserted into the connecting through hole, and the mounting base is fixedly connected to the plug body by the connecting screw.

[0010] The protective base layer has threaded holes at both ends, and the plug-in frame and the wire fixing seat also have threaded holes at their ends. The internal threads of the threaded holes are connected to fixing studs, which are used to fix the plug-in frame and the wire fixing seat to both ends of the protective base layer.

[0011] The outer side of the wire fixing seat is inserted into the wire probe housing. The wire probe housing has a positioning socket, and the wire fixing seat has a positioning protrusion. The positioning protrusion on the wire fixing seat is engaged with the positioning socket on the wire probe housing.

[0012] The present invention also provides a method for using a waterproof protection fixing device for a spring-loaded broken wire detector circuit, comprising the following steps: Step 1, Pre-installation and positioning: Insert the wire body into the wire fixing seat, align the positioning protrusion of the wire fixing seat with the positioning socket of the probe housing, and insert it to make the probe housing and the wire fixing seat limit connection; Align the two ends of the protective base layer with the threaded holes of the wire fixing seat and the plug frame respectively, and insert the fixing studs to lock the three together; Fit the mounting base tightly against the inside of the plug body, and lock it in place by passing the connecting screw through the connecting through hole in the hidden groove; Step 2: Snap-fit ​​sealing for use: Align the plug frame with the plug slot and push it inwards. The side wall of the plug slot presses against the snap-fit ​​connector, compressing the snap-fit ​​spring and retracting it into the groove. After insertion, the snap-fit ​​connector pops out and snaps into the snap-fit ​​hole to lock in place. The protective component seals and wraps the connection between the wire body and the plug body. Connect to the texturing machine for normal operation. During operation, the nylon protective inner layer buffers vibration, is wear-resistant and bend-resistant, and the polyethylene film waterproof outer layer prevents moisture, oil, and dust from entering the gaps in the wiring. Step 3, Inspection and Disassembly: Pull the operating panels on both sides simultaneously. The connecting rod will move along the connecting slide hole to drive the clamp connector to compress the clamp spring and disengage from the clamp hole. Pull out the plug frame to separate the protective component from the plug body. Loosen the fixing screws to disassemble the protective base layer, wire fixing seat, and plug frame. Inspect the circuit. After the inspection is completed, repeat Step 1 and Step 2 to reassemble and use.

[0013] The present invention provides a waterproof protection and fixing device for a texturing wire breakage detector circuit and its usage method. The protective component of the wire detector limits and fixes the wire body through the wire fixing seat inside the wire detector housing. Combined with the protective base layer with multiple embedded protective skeletons, it provides all-round support and protection for the wire body, effectively resisting equipment vibration and external pulling force, and preventing wire bending and breakage, and loosening of wiring. The protective base layer adopts a composite structure of nylon protective inner layer and polyethylene film waterproof outer layer. The inner layer is tough, wear-resistant and flexurally resistant, and can protect the wire body from wear. The outer layer is waterproof and seepage-proof, and can effectively block the intrusion of water vapor, oil and dust in the texturing workshop. At the same time, the protective base layer is fixed to the plug body by the end mounting component, realizing the sealing protection at the connection between the housing and the plug. This design eliminates poor contact and short-circuit faults in the wiring, significantly improving the stability and lifespan of the wire probe wiring connection and ensuring continuous and accurate wire breakage detection. During assembly, the plug frame at the end of the protective base is aligned with the plug slot on the plug mounting base and inserted. During insertion, the clamping spring is compressed and retracted into the groove under the external force of the clamping connector. After insertion, the clamping connector pops out under the elastic force of the clamping spring and snaps into the clamping hole, achieving quick snap-fit ​​fixation between the plug frame and the mounting base. This ensures that the protective components are firmly connected to the plug body, preventing the protective structure from loosening or shifting due to equipment vibration, and ensuring the sealing and integrity of the wiring protection. At the same time, it is easy to disassemble and assemble, facilitating subsequent wiring maintenance and component replacement, and effectively improving the assembly efficiency and connection reliability of the wiring harness protection structure.

Detailed Implementation

[0015] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0016] Example 1:

[0017] like Figures 1-4 As shown, this invention discloses a waterproof protection and fixing device for a spring-loaded broken wire detector circuit, including a wire detector housing 1. One end of the wire detector housing 1 is provided with a wire body 2, and the other end of the wire body 2 is fixedly connected to a plug body 3. A protective component 5 is provided between the wire detector housing 1 and the plug body 3. The protective component 5 includes a wire fixing seat 51. One end of the wire fixing seat 51 is connected to the wire detector housing 1, and the other end of the wire fixing seat 51 is fixedly connected to a protective base layer 53. Multiple protective frames 52 are provided inside the protective base layer 53. The other end of the protective base layer 53 is fixedly connected to an installation component 4. The protective component 5 is interlocked with the plug body 3 through the installation component 4. The protective base layer 53 includes a protective inner layer 531 provided outside the protective frames 52. A waterproof outer layer 532 is fixedly connected to the outside of the protective inner layer 531. The protective inner layer 531 is a nylon material layer, and the waterproof outer layer 532 is a polyethylene film layer.

[0018] refer to Figures 1-3 The mounting component 4 includes a mounting base 41. One end of the mounting base 41 is fixedly connected to the plug body 3, and the other end of the mounting base 41 has a plug groove 42. Both sides of the plug groove 42 have snap-fit ​​holes 43. A plug frame 44 is fixedly connected to the outer side of the protective base layer 53. The plug frame 44 and the plug groove 42 are plugged into each other. Both sides of the plug frame 44 have grooves 45. A snap-fit ​​spring 46 is fixedly connected inside the groove 45. The other end of the snap-fit ​​spring 46 is fixedly connected to a snap-fit ​​connector 47. The snap-fit ​​connector 47 is snapped into the snap-fit ​​hole 43. During assembly, the plug frame 44 at the end of the protective base layer 53 is aligned with the plug groove 42 on the plug mounting base 41 and inserted. During the insertion process, the snap-fit ​​connector 47 is squeezed and compressed by the groove wall, causing the snap-fit ​​spring 46 to retract into the groove 45. After being inserted into place, the snap-fit ​​connector 47 pops out under the elastic force of the snap-fit ​​spring 46 and snaps into the snap-fit ​​hole 43, realizing the quick snap-fit ​​fixation between the plug frame 44 and the mounting base 41.

[0019] refer to Figure 3 A connecting sliding hole 48 is provided on the outer side wall of the groove 45. A connecting rod 49 is fixedly connected to the outer side of the snap-fit ​​connector 47. An operating plate 50 is fixedly connected to the other end of the connecting rod 49. The connecting rod 49 and the connecting sliding hole 48 are slidably connected to each other. The connecting rod 49 extends to the outside of the plug frame 44. When inspecting and disassembling the protective component 5, the outer operating plate 50 is pulled, and the connecting rod 49 slides inward along the connecting sliding hole 48, which drives the snap-fit ​​connector 47 to compress the spring and retract into the groove 45, releasing the locking engagement between the snap-fit ​​connector 47 and the snap-fit ​​hole 43. The plug frame 44 can then be pulled out from the plug slot 42, realizing the rapid separation of the protective component 5 from the plug body 3.

[0020] refer to Figure 3 The mounting base 41 has a hidden groove 8 on its outer side and a connecting through hole 9 inside the hidden groove 8. A connecting screw is inserted into the connecting through hole 9. The mounting base 41 is fixedly connected to the plug body 3 by the connecting screw. During assembly, the mounting base 41 is placed in the preset position of the plug body 3, so that the connecting through hole 9 in the hidden groove 8 is aligned with the threaded hole of the plug body 3, and the connecting screw is inserted and tightened to firmly fix the mounting base 41 on the plug body 3.

[0021] refer to Figure 3 The protective base layer 53 has threaded holes 10 at both ends. The plug-in frame 44 and the wire fixing seat 51 also have threaded holes 10. The internal threads of the threaded holes 10 are connected to fixing studs 11, and the fixing studs 11 are threadedly connected to the threaded holes 10. During assembly, the two ends of the protective base layer 53 are aligned with the installation positions of the wire fixing seat 51 and the plug-in frame 44, so that the threaded holes 10 on the protective base layer 53 are aligned with the threaded holes 10 at the two locations. The fixing studs 11 are screwed in to lock the three together. This allows the protective base layer 53 to be stably mounted on the outside of the wire body 2, preventing the protective base layer 53 from shifting or falling off due to long-term vibration of the equipment. This ensures the protective structure's support and protection effect on the cable, improves the overall connection strength, prevents the protective structure from loosening and failing, and is easy to disassemble and assemble, facilitating the inspection and replacement of parts.

[0022] refer to Figure 2 The outer side of the wire fixing seat 51 is inserted into the wire probe housing 1. The outer side of the wire probe housing 1 is provided with a positioning socket 7, and the outer surface of the wire fixing seat 51 is provided with a positioning protrusion 6. The positioning socket 7 of the wire probe housing 1 and the positioning protrusion 6 of the wire fixing seat 51 are inserted into each other. During installation, the positioning protrusion 6 of the wire fixing seat 51 is aligned with the positioning socket 7 of the wire probe housing 1 and inserted. The bidirectional insertion achieves precise positioning of the wire fixing seat 51, preventing the fixing seat from rotating circumferentially or sliding axially when the equipment is vibrating. This ensures that the cable is positioned stably, avoids loosening of the wiring position due to force, and also allows the protective component 5 to be precisely aligned and assembled with the housing, improving the installation accuracy and connection reliability of the overall structure.

[0023] Usage and advantages: During installation, first insert the wire fixing seat 51 into the positioning socket 7 of the wire probe housing 1 to achieve bidirectional limiting. Then, use the fixing studs 11 to lock the two ends of the protective base layer 53 between the wire fixing seat 51 and the plug frame 44. The protective frame 52 is wrapped with a protective base layer 53 composed of a nylon protective inner layer 531 and a polyethylene waterproof outer layer 532, which provides protection against bending, wear and water for the wire body 2. The mounting seat 41 is fixed to the plug body 3 with a hidden connecting screw. After the plug frame 44 is inserted into the plug slot 42, it is locked by the snap connector 47 and the snap spring 46. When maintenance is required, the operating plate 50 can be pulled to unlock and disassemble. The whole structure can effectively resist water and gasoline pollution in the texturing workshop and vibration of equipment operation, avoid line wear, water ingress and short circuit, ensure stable wire probe line connection, facilitate disassembly and maintenance, and greatly extend the service life of the wire break detector.
