Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more particularly to a wire harness and a lighting fixture thereof. Background Technology

[0002] Currently, the most common method for securing and organizing cables in the industry is using cable ties. Traditional cable ties (usually made of plastics such as nylon) use a ratchet on the body and a self-locking mechanism at the head to create a one-way lock once tightened, making them impossible to loosen directly. While this method offers advantages such as low cost and secure binding, it also has a significant drawback: it is extremely difficult to disassemble and is generally considered a disposable product.

[0003] When it's necessary to maintain the wiring harness, replace a cable, or adjust its layout, users often have no choice but to use scissors, blades, or other tools to cut the cable ties. This destructive disassembly method has several drawbacks: 1. When using sharp tools for cutting, especially in confined spaces or poorly lit environments, it is easy to scratch the cable insulation layer or even damage the wire core, which may cause personal injury to the operator. It is inconvenient to operate and poses safety hazards. 2. Each adjustment requires new cable ties, and the old cable ties that are cut are discarded, resulting in material waste and environmental pollution.

[0004] 3. Cut cable ties are completely ineffective and cannot be reused. For equipment that needs to be opened and closed frequently for maintenance (such as server racks, experimental instrument platforms, etc.), repeatedly binding new cable ties greatly increases maintenance costs and time costs. Summary of the Invention

[0005] To solve one of the above-mentioned technical problems, this invention provides a reusable snap-on wire harness that can be manually locked or unlocked without tools, and a lighting fixture that uses the wire harness to organize cables.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A wire harness includes a wire harness tube with a semi-enclosed structure. The wire harness tube has an opening along its length. A wire harness strip is movably disposed at one edge of the opening, and a locking protrusion is disposed at the other edge of the opening. The free end of the wire harness strip is sequentially connected to a first connecting block and a second connecting block. The first connecting block has a first connecting end and a second connecting end. The first connecting block is connected to the wire harness strip through the first connecting end, and the first connecting block is connected to the second connecting block through the second connecting end. The second connecting block extends to both sides in the width direction of the second connecting end, and the second connecting block is divided into a fastening part and a linkage part with the second connecting end as the dividing line. The fastening part and the first connecting block form a locking groove. By operating the linkage part, the locking groove and the locking protrusion are fastened together. After fastening, the wire harness tube and the wire harness strip form a closed loop wire harness hole.

[0007] Further defined, the card protrusion is provided with limiting posts on both sides, and a limiting groove adapted to the width of the first connecting block is formed between the two limiting posts.

[0008] Further defined, the protrusion has an inclined surface that slopes outward from top to bottom, and the inclined surface allows the first connecting block to slide on its surface to guide the slot to engage with the protrusion.

[0009] Further defined, the bottom of the protrusion is a flat portion, and after fastening, the first connecting block can abut against the flat portion.

[0010] Further specified, the inner side of the cable tie is provided with a soft pad.

[0011] Further defined, the wire harness tube is curved in an arc shape along its length.

[0012] A lamp includes a base, on which a support arm is fixedly mounted. The support arm is rotatably connected to a head via a pivot assembly. The pivot assembly has a first through hole. The back of the head is provided with a heat sink assembly consisting of several heat sink fins. The heat sink fins have notches at the same positions to form a groove. The back of the head is also provided with a second through hole. Multiple power cables inside the base pass sequentially through the interior of the support arm, the first through hole, the groove, the cable harness, and the second through hole before entering the interior of the head.

[0013] Further defined, the back of the head is provided with a fan shroud, and multiple fans for cooling the heat sink assembly are fixedly installed inside the fan shroud.

[0014] By adopting the above technical solution, the present invention has at least the following beneficial effects: When fastening, the operator can pry the linkage part down to engage the cable tie's slot and protrusion. When unfastening, the operator pry the linkage part up again to disengage the cable tie's slot and protrusion. The cable tie harness of this product can be reused, reducing resource waste and saving costs. No tools are needed; locking and unlocking can be completed manually, greatly increasing the product's ease of use. Attached Figure Description

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] In the description of this invention, it should be understood that the terms "center," "middle," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0018] As attached Figure 1 and attached Figure 2 As shown, a wire harness includes a wire harness tube 1 with a semi-enclosed structure. The wire harness tube 1 has an opening 2 along its length. It can be understood that the opening 2 is formed by cutting a section of tubular body in half from the head end to the tail end along its length, so as to facilitate the insertion of the power cord into the tube for tight bundling.

[0019] A cable tie 3 is movably disposed on one edge of the opening 2, and a locking protrusion 4 is disposed on the other edge of the opening 2. The free end of the cable tie 3 is sequentially connected to a first connecting block 5 and a second connecting block 6. The first connecting block 5 has a first connecting end and a second connecting end. The first connecting block 5 is connected to the cable tie 3 through the first connecting end, and the first connecting block 5 is connected to the second connecting block 6 through the second connecting end. The second connecting block 6 extends to both sides in the width direction of the second connecting end, and the second connecting block 6 is divided into a fastening part 61 and a linkage part 62 with the second connecting end as the dividing line. The fastening part 61 and the first connecting block 5 form a locking groove 63. By operating the linkage part 62, the locking groove 63 and the locking protrusion 4 are fastened together. After fastening, the cable harness tube 1 and the cable tie 3 form a closed loop cable hole 10.

[0020] Preferably, two cable ties 3 are provided, respectively located near both ends of the cable harness tube 1, to enhance the tightness of the power cord and reduce the risk of loosening. When fastening, the operator can pry the linkage part 62 down to engage the slot 63 of the cable ties 3 with the protrusion 4. When unfastening, the operator prys the linkage part 62 up again to disengage the slot 63 of the cable ties 3 from the protrusion 4. The cable harness of this product is reusable, reducing resource waste and saving costs; locking and unlocking can be completed manually without the need for tools, greatly increasing the product's ease of use.

[0021] In some embodiments, limiting posts 7 are provided on both sides of the buckle 4, and a limiting groove 70 adapted to the width of the first connecting block 5 is formed between the two limiting posts 7. After fastening, the limiting posts 7 can limit the movement of the cable tie 3 in the length direction of the cable tie tube 1, increase the constraint on the degree of freedom of the cable tie 3 in multiple directional dimensions, and reduce the risk of loosening or disengagement.

[0022] In some embodiments, the latching protrusion 4 is provided with an inclined surface 41 that slopes outward from top to bottom. The inclined surface 41 allows the first connecting block 5 to slide on its surface to guide the latching groove 63 to easily engage with the latching protrusion 4, thereby improving the engagement efficiency. The bottom of the latching protrusion 4 is a flat portion 42. After engagement, the first connecting block 5 can abut against the flat portion 42, thereby increasing the stability of the engagement.

[0023] In some embodiments, a soft pad 30 is provided on the inner side of the cable tie 3. The pad 30 can effectively protect the power cord and reduce wear on the power cord caused by excessive tightening.

[0024] In some embodiments, the wire harness tube 1 is curved in an arc shape along its length. This shape of the wire harness tube 1 is suitable for cable layouts at corners, reducing the risk of breakage caused by excessive bending of the power cord.

[0025] As attached Figure 3As shown, a lighting fixture includes a base 81, on which a support arm 82 is fixedly mounted. The support arm 82 is rotatably connected to a head 83 via a pivot assembly 80. The pivot assembly 80 has a first through hole 801. A heat sink assembly 84, composed of several heat sink fins, is provided on the back of the head 83. The heat sink fins have notches at the same positions to form a recessed groove 840. A second through hole 830 is also provided on the back of the head 83. Multiple power cables inside the base 81 pass sequentially through the interior of the support arm 82, the first through hole 801, the recessed groove 840, the cable harness, and the second through hole 830 before entering the interior of the head 83. The cable harness of this product is used to organize the cable layout of the lighting fixture, optimizing space and improving appearance. It also effectively prevents tripping hazards, equipment detachment and damage, and cable wear and breakage caused by scattered or tangled cables, thereby improving safety and extending the lifespan of the equipment.

[0026] A fan cover 85 is provided on the back of the head 83, and a plurality of fans 86 are fixedly installed inside the fan cover 85 to dissipate heat from the heat sink assembly 84, thereby improving the heat dissipation efficiency of the lamp.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various equivalent changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
