Description

Technical Field

[0001] This utility model relates to the field of electrical installation technology, and more specifically, to an electrical installation protection wiring harness device. Background Technology

[0002] During the installation and operation of electrical equipment, wire harnesses, as the core carrier of power and signal transmission, directly affect the overall performance of the equipment due to their safety and stability. However, in practical applications, wire harnesses often face interference from multiple environmental and mechanical factors, such as dust erosion in industrial workshops, moisture penetration in humid environments, material aging caused by alternating high and low temperatures, and friction, pulling, or entanglement caused by equipment vibration. These factors not only accelerate the wear and cracking of the wire harness insulation layer but may also cause safety hazards such as short circuits and leakage, and in severe cases, even lead to major accidents such as equipment shutdown and fires. Therefore, effective protection and management of wire harnesses has become a critical requirement in the field of electrical installation.

[0003] In the prior art, there are many types of devices for wire harness protection, including wire harness sleeves such as heat shrink sleeves, nylon cloth sleeves, silicone sleeves, and PTFE sleeves; as well as wire harness fixing groove devices, nylon Velcro sleeves, wire harness protection boxes, and wire harness shrinking structures (upper / lower sleeves) with protective features. Among these, the wire harness shrinking structure (upper / lower sleeves) with protective features, such as the one disclosed in patent number CN202422146782.1, describes a structure where "the wire harness is fitted inside the upper and lower guide tubes, and the upper and lower sleeves protect the wire harness, preventing direct contact between the wire harness and the outside environment, thereby improving the service life of the wire harness; by rotating the upper sleeve, the upper and lower guide tubes are misaligned, and excess wire harness is stored inside the upper and lower sleeves, ensuring cleanliness around the terminals."

[0004] The wire harness retraction structure with protective features disclosed in the aforementioned patent is convenient for storing a small amount of excess wire harness. However, if the wire harness is too long, it is easy for it to accumulate mess inside the sleeve, which increases the risk of friction and wear. In view of this, we propose an electrical installation protection wire harness device. Utility Model Content

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] Please see Figures 1-5The present invention provides a technical solution including a wire box A1 and a wire box B8. The wire box A1 can cooperate with the wire box B8. The long ends of the wire box A1 and the wire box B8 are provided with sliding grooves 3. The sliding grooves 3 of the wire box A1 and the sliding grooves 3 of the wire box B8 are symmetrical and staggered. The wire box A1 and the wire box B8 are fixed with ratchet strips 2 on both sides.

[0034] In another embodiment of the present invention, preferably, several wire grooves 9 are provided on both sides of the short ends of wire box A1 and wire box B8, and a flexible sheet 10 is bonded inside the wire grooves 9.

[0035] Junction box A1 and junction box B8 are preferably made of flame-retardant materials such as ABS, which have excellent insulation and impact resistance. The two are detachable by means of a snap-fit ​​structure on the side or mounting plate and bolts (forming a complete protective cavity when closed).

[0036] Both sides of the long ends of junction boxes A1 and B8 are provided with strip grooves 3. The width of the strip grooves 3 is adapted to the sliding parts of the pullers (pullers A4 and pullers B5), and is symmetrical and staggered. That is, the grooves 3 of junction box A1 and B8 are symmetrically distributed along the connecting surface of junction box A1 and junction box B8, and a certain amount of misalignment is set to ensure that when pullers A4 and pullers B5 slide, the comb teeth 4012 structure can form an interlocking fit to avoid motion interference.

[0037] Several wire grooves 9 are provided on both sides of the short end of the junction box (i.e., the end face perpendicular to the long end). A flexible sheet 10 is bonded to the inner wall of the wire groove 9. It has good elasticity and wear resistance. When the wire harness passes through, the flexible sheet 10 can fit tightly against the surface of the wire harness, which not only seals the gap between the wire groove 9 and the wire harness (preventing dust and moisture from entering), but also buffers the friction between the wire harness and the edge of the wire groove 9 when the wire harness vibrates, thus avoiding wear of the insulation layer.

[0038] The puller A4 slides within the groove 3 of the wire box A1 and includes a comb A401;

[0039] In another embodiment of the present invention, preferably, there are a plurality of combs A401 arranged in parallel to each other, and end strips A402 are provided at both ends of the combs A401.

[0040] The puller B5 slides in the groove 3 of the wire box B8 and includes a comb B501 symmetrically arranged with the comb A401. There are several combs B501 arranged in parallel to each other, and end strips B502 are provided at both ends of the comb B501.

[0041] In another embodiment of the present invention, preferably, the structure of comb B501 is the same as that of comb A401, both including comb bar 4011, and a plurality of comb teeth 4012 are fixed in a straight line equidistant array on the outer side wall of comb bar 4011.

[0042] The puller A4 is slidably connected to the groove 3 of the junction box A1, and the puller B5 is slidably connected to the groove 3 of the junction box B8. The two are symmetrical and compatible.

[0043] Comb A401 and comb B501 have the same structure. Each group contains several parallel comb bars 4011. The outer wall of the comb bar 4011 has several comb teeth 4012 arranged equidistantly along the length direction. The gap between the comb teeth 4012 is aligned with the wire groove 9 and allows the wire to be protected to pass through. The comb teeth 4012 of comb A401 and comb B501 correspond one-to-one (that is, the comb teeth 4012 of comb A401 are directly opposite the comb bars 4011 of comb B501), ensuring that the wire bundle can be parallel to each other when passing through, and avoiding tangling.

[0044] End bar A402 and end bar B502 are preferably rectangular frame structures.

[0045] The elastic ratchet 6 has several sets and is respectively installed at both ends of the cable puller A4 and the cable puller B5, and can cooperate with the ratchet 2.

[0046] In another embodiment of the present invention, preferably, the elastic pawl member 6 includes a guide assembly 601 installed at both ends of the end bar A402 and the end bar B502, a spring 602 is sleeved on the outer wall of the guide assembly 601, and a pawl body 603 is installed at the end of the guide assembly 601.

[0047] Each set of elastic pawls 6 contains two (installed at both ends of end bar A402 and end bar B502 respectively), and consists of a guide assembly 601 (the guide assembly 601 may include a guide sleeve and a guide post slidably connected in the guide sleeve), a spring 602, and a pawl body 603 (the tooth shape is adapted to the pawl).

[0048] Both junction boxes A1 and B8 have ratchet bars 2 on their long outer side walls. When the pawl body 603 engages with the ratchet bar 2, the spring 602 is in a slightly compressed state, providing continuous preload to ensure reliable positioning. When the cable pullers (cable pullers A4 and B5) are pushed to slide along the slide groove 3, the pawl body 603 slides unidirectionally along the tooth surface of the ratchet bar 2. If the retracted length needs to be adjusted, pressing the pawl body 603 to compress the spring 602 will disengage the engagement and allow for reverse sliding.

[0049] The spiral protective sleeve 7 is installed inside the wire box B8 and includes the spiral sleeve body 701.

[0050] In another embodiment of the present invention, preferably, a hook and loop fastener B702 is installed at the end of the spiral sleeve body 701, and a hook and loop fastener A11 is detachably connected to the outer wall of the hook and loop fastener B702. The hook and loop fastener A11 is installed at the corresponding position of the wire groove 9 inside the wire box B8.

[0051] The spiral protective sleeve 7 is located inside the junction box B8. The main body is the spiral sleeve body 701, which has good flexibility and bending resistance.

[0052] The end of the spiral sleeve body 701 is fixed with a Velcro B702 (hook side), and the inside of the wire box B8 is fitted with a Velcro A11 (rough side) corresponding to the wire groove 9 to ensure that the spiral sleeve is stably fixed. When the wire harness passes through the wire groove 9, the spiral sleeve body 701 can wrap the exposed wire harness and disperse the bending stress through the spiral structure to reduce the fatigue damage caused by repeated bending of the wire harness.

[0053] Working principle: This embodiment provides an electrical installation protection wiring harness device. When in use,

[0054] When the length of the wire harness to be protected is long or needs to be arranged, first separate wire box A1 and wire box B8. Pass the wire harness through the wire groove 9 of wire box A1 (or wire box B8) in sequence (the flexible sheet 10 is adapted to the diameter of the wire harness for sealing). Wrap the spiral protective sleeve 7 around the wire harness one by one and pass it through the gap of the comb teeth 4012 of comb A401 and comb B501 one by one. Use Velcro A11 and Velcro B702 to stick the spiral protective sleeve 7 into the wire box A1. Then close the wire box. At this time, the wire harness is evenly clamped between the two sets of comb teeth 4012 (comb A401 and comb B501), achieving a preliminary orderly arrangement.

[0055] Push the cable puller A4 and cable puller B5 to slide along the slide groove 3 (due to the misaligned design of the slide groove 3, the relative distance between comb A401 and comb B501 gradually increases), and the excess cable bundle forms several parallel wavy lines under the guidance of the comb teeth 4012. When the storage length reaches the required level, the elastic pawl 6 automatically engages with the ratchet 2 for positioning. At this time, the cable bundle is inside the cable box, providing excellent dustproof, moistureproof, and impact-proof effects.

[0056] To inspect the wiring harness, simply separate junction box A1 and junction box B8, press the elastic ratchet 6 to release the positioning, and slide the puller (puller A4, puller B5) in the opposite direction to release the wiring harness. If you need to change the wiring harness specification, simply replace the spiral protective sleeve 7 with the corresponding diameter (the Velcro connection allows for quick disassembly and assembly), making it highly adaptable.

[0057] Cable pullers A4 and B5 are slidably connected inside cable boxes A1 and B8, respectively. The combs A401 of cable puller A4 and B501 of cable puller B5 are parallel and staggered. The long cable bundle to be protected is passed through the combs B501 of comb A401. By adjusting the relative distance between the combs B501 of comb A401, a long cable bundle can be stored. The cable bundle is separated by comb teeth 4012, and the cable bundles are parallel to each other, making it difficult for them to pile up, become messy and tangled. The cable bundle has a good anti-pilling effect. It is also equipped with a spiral protective sleeve 7. When it is difficult to pass the cable bundle to be protected, cable boxes A1 and B8 can be separated to quickly wrap the cable bundle to be protected.

[0058] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
