Technical Field

[0001] This utility model relates to the field of wire harness product technology, and specifically to a rainproof wire harness for outdoor lighting fixtures. Background Technology

[0002] Authorization announcement number CN213656617U discloses an intelligent anti-glare LED downlight. This intelligent anti-glare LED downlight includes a lamp body. An LED circuit board is fixedly connected to the middle of the top wall of the lamp body. Reflective paper is fixedly connected to the inner wall of the lamp body. A diffuser plate is fixedly connected to the lower surface of the LED circuit board. A silicone sleeve is provided on the top wall of the lamp body. A fixing through hole is formed on the outer surface of the silicone sleeve, and a fixing screw is disposed inside the fixing through hole. An iron sheet is fixedly connected to the lower surface of the silicone sleeve by the fixing screw. A threaded hole is formed on the lower surface of the lamp body, and a screw is threaded into the threaded hole. A male wire is fixedly connected to the top of the lamp body. A power plug is fixedly connected to the end of the male wire away from the lamp body. A wire clip is fixedly connected to the outer surface of the male wire, and the male wire is fixedly connected to the lamp body through the wire clip.

[0003] However, the wire clamp needs to be locked to the top of the lamp body with screws, and the wire clamp is used to hold and fix the male wire to the lamp body, thus fixing the male wire to the lamp body. However, the clamping force between the wire clamp and the male wire is limited. When the male wire is subjected to a large tensile force, the male wire may detach from the wire clamp, causing the male wire to break from the lamp body and affecting normal electrical conductivity. In addition, there is no waterproof structure designed between the male wire and the lamp body. If the above-mentioned intelligent anti-glare LED downlight is used outdoors, there is a possibility of water ingress between its male wire and the lamp body, affecting the normal use of the product.

[0004] In view of the above, the inventors propose the following technical solution. Summary of the Invention

The bracket has several second through holes beside the first through holes. The wiring harness body includes multiple parallel wires, an integrally formed plastic base fixed to the lower part of the wires, and a plug disposed at the upper end of the wires and forming an electrical connection. The lower ends also extend beyond the lower end face of the plastic base; the plastic base is inserted and fixed in the limiting slot of the support base, and the lower end of the wire passes through the first wire hole from top to bottom, then bends to fit the lower end of the bracket, then bends from bottom to top and passes through the second wire hole to be exposed at the upper end of the bracket; the bracket is also provided with a waterproof rubber pad, the insulation layer of the lower end of the wire passes through the third wire hole on the waterproof rubber pad and forms a sealed contact, and the conductor of the lower end of the wire protrudes from bottom to top and is exposed beyond the upper end face of the waterproof rubber pad, so as to pass through and solder to the pads of the PCB board of the outdoor lighting fixture.

[0007] Furthermore, in the above technical solution, the distance between two adjacent second threading holes is less than the distance between two adjacent first threading holes.

[0008] Furthermore, in the above technical solution, the bracket is also provided with a recessed groove, which passes through the first wire hole, the second wire hole and the limiting slot; the waterproof gasket is disposed in the recessed groove.

[0009] Furthermore, in the above technical solution, the waterproof pad is formed by injecting waterproof adhesive into the settling tank and then curing it. The waterproof pad also partially integrates into and fills the gap between the lower end of the wire and the second wire hole, and the waterproof pad wraps around the insulation layer of the wire to form the third wire hole; or, the waterproof pad is a rubber pad with self-adhesive backing. The rubber pad is embedded in the settling tank and then fixed to the bottom of the settling tank by its backing adhesive, and the diameter of the third wire hole is smaller than the outer diameter of the insulation layer of the wire, so that the insulation layer of the wire and the third wire hole form an interference fit and are tightly fastened.

[0011] Furthermore, in the above technical solution, the plastic base is integrally molded from soft rubber and is fastened to the limiting slot of the support base by an interference fit.

[0012] Furthermore, in the above technical solution, the upper end of the plastic base is also provided with a net tail, which wraps around the insulation layer of all wires to enhance the flexibility of the wires.

[0013] Furthermore, in the above technical solution, the plug includes a plastic shell and a plurality of terminals inserted and fixed inside the plastic shell.

This utility model uses a bracket to fix the outdoor lamp, which enhances the stability of the fixed assembly with the outdoor lamp. The main body of the wire harness is fixed to the limiting slot of the support base through the plastic seat at the lower part of the wire, forming a primary fixation. The lower end of the wire passes through the first wire hole from top to bottom, then bends to fit the lower end of the bracket, and then bends from bottom to top and passes through the second wire hole to be exposed at the upper end of the bracket. In this way, the wire itself passes through the first and second wire holes and bends relative to the bracket, thereby achieving the purpose of secondary fixation. Finally, the conductor at the lower end of the wire is used to pass through and solder to the pads of the PCB board of the outdoor lamp, thereby achieving the purpose of tertiary fixation. This results in extremely strong tensile strength, which ensures that the main body of the wire harness forms a stable assembly with the bracket and the outdoor lamp, making it less likely to fall off, ensuring product quality, and enabling the wire to form a stable electrical conduction with the PCB board of the outdoor lamp, ensuring the normal use of the lamp and helping to improve the service life of the lamp.

[0017] 2. The bracket is also provided with a waterproof rubber pad. The insulation layer at the lower end of the wire passes through the third wire hole on the waterproof rubber pad and forms a sealed contact. The conductor at the lower end of the wire protrudes from bottom to top and is exposed outside the upper surface of the waterproof rubber pad. This can achieve waterproof performance and ensure the normal use of the lamp. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0020] See Figure 1-5 As shown, an outdoor lighting fixture rainproof wiring harness includes: a bracket 1 and a wiring harness body 300, the wiring harness body 300 including a wire 3, a plastic base 4 and a plug 5.

[0021] The bracket 1 is used to fix outdoor lighting fixtures. It is provided with a support base 2, which has a limiting slot 21. The bottom of the limiting slot 21 has several first wire-passing holes 22 that penetrate the lower end face of the support base 2. The bracket 1 has several second wire-passing holes 11 on the side of the first wire-passing holes 22. The wire harness body 300 includes multiple parallel wires 3, a plastic base 4 integrally formed and fixed to the lower part of the wires 3, and a plug 5 disposed on the upper end of the wires 3 and forming an electrical connection. The lower ends of the wires 3 also extend beyond the lower end face of the plastic base 4. The plastic base 4 is inserted and fixed in the limiting slot 21 of the support base 2, and the lower end of the wire 3 passes through the first wire hole 22 from top to bottom and is bent to fit the lower end of the bracket 1, and then bends from bottom to top and passes through the second wire hole 11 to be exposed on the upper end of the bracket 1; the bracket 1 is also provided with a waterproof rubber pad 6, the insulation layer 31 of the lower end of the wire 3 passes through the third wire hole 61 on the waterproof rubber pad 6 and forms a sealed contact, and the conductor 32 of the lower end of the wire 3 protrudes from bottom to top and is exposed outside the upper end surface of the waterproof rubber pad 6, so as to pass through and solder to the pads of the PCB board of the outdoor lamp. In other words, this utility model uses a bracket 1 to fix the outdoor light fixture, which enhances the stability of the fixed assembly with the outdoor light fixture. The main body 300 of the wire harness is inserted and fixed to the limiting slot 21 of the support base 2 through the plastic seat 4 at the lower part of the wire 3, forming a one-time fixation. The lower end of the wire 3 passes through the first wire hole 22 from top to bottom, then bends to fit against the lower end of the bracket 1, and then bends from bottom to top and passes through the second wire hole 11 to be exposed at the upper end of the bracket 1. In this way, the wire 3 passes through the first wire hole 22 and the second wire hole 11 respectively. The bracket 1 is bent to achieve secondary fixation. Finally, the conductor 32 at the lower end of the wire 3 is threaded and soldered to the pads of the PCB board of the outdoor lighting fixture, thus achieving tertiary fixation and providing strong tensile strength. This ensures a stable assembly between the wire harness body 300, the bracket 1, and the outdoor lighting fixture, preventing detachment and guaranteeing product quality. It also ensures stable electrical conductivity between the wire 3 and the PCB board of the outdoor lighting fixture, guaranteeing normal operation and extending the lifespan of the lighting fixture. Furthermore, the bracket 1 is equipped with a waterproof gasket 6. The insulation layer 31 at the lower end of the wire 3 passes through the third through-hole 61 on the waterproof gasket 6, forming a sealed contact. The conductor 32 at the lower end of the wire 3 protrudes upwards and is exposed on the upper surface of the waterproof gasket 6, achieving waterproof performance and ensuring normal operation of the lighting fixture.

[0022] Since the plastic base 4 at the lower part of the wire 3 is inserted and fixed in the limiting slot 21 of the support base 2, it is convenient to pass the wire 3 through the first wire hole 22. As a result, the gap between two adjacent first wire holes 22 is set to be small, or even the two adjacent first wire holes 22 are connected to each other so as to be the same as the gap between two adjacent wires 3. In this embodiment, the two adjacent wires 3 are connected so that there is no gap between them, so that the first wire hole 22 can be installed along the part of the lower end of the wire 3 that just extends out of the plastic base 4, without having to branch the two adjacent wires 3, thus ensuring product quality.

[0023] The distance between two adjacent second wire holes 11 is smaller than the distance between two adjacent first wire holes 22. As a result, when the wire 3 passes through the second wire hole 11, the distance between the two adjacent wires 3 needs to be increased before passing through the second wire hole 11. This can increase the tensile strength and also make it easier for the outdoor lamp to be installed on the bracket 1. The PCB board of the outdoor lamp can be immediately placed on the conductor 32 under the wire 3, making the installation more convenient and efficient.

[0024] The bracket 1 is also provided with a recessed groove 12, which passes through the first wire hole 22, the second wire hole 11 and the limiting slot 21; the waterproof rubber pad 6 is disposed in the recessed groove 12, which enables the waterproof rubber pad 6 to be stably installed on the bracket 1.

[0025] The waterproof gasket 6 can be installed in the settling tank 12 in the following two ways: The first method: The waterproof pad 6 is formed by injecting waterproof adhesive into the settling tank 12 and then curing it. The waterproof pad 6 is also partially integrated into and fills the gap between the lower end of the wire 3 and the second wire hole 11. The waterproof pad 6 wraps the insulation layer 31 of the wire 3 to form the third wire hole 61.

[0026] The second method: The waterproof pad 6 is a self-adhesive rubber pad. After the rubber pad is embedded in the sink 12, it is fixed to the bottom of the sink 12 by its back adhesive. The diameter of the third wire hole 61 is smaller than the outer diameter of the insulation layer 31 of the wire 3, so that the insulation layer 31 of the wire 3 and the third wire hole 61 form an interference fit and are tightly fastened.

[0027] Regardless of the method, it can form a sealed assembly between the waterproof gasket 6 and the wire 3, and can make the wire 3 more stably installed on the bracket 1, and can improve the sealing performance.

[0028] The limiting slot 21 is an open slot that extends through the upper surface and an outer side of the support base 2. This design ensures the plastic base 4 is properly inserted into the limiting slot 21, achieving an interference fit for secure fastening. The plastic base 4 is integrally molded from soft rubber and is secured to the limiting slot 21 of the support base 2 via an interference fit, resulting in more stable assembly. Furthermore, because the plastic base 4 is fixedly inserted into the limiting slot 21, the support base 2 can stably limit its position, preventing it from falling off during wire swaying and improving product quality.

[0029] The bracket 1 is made of aluminum, and the support base 2 is integrally formed on the bracket. The overall structure is stable and strong, and it can also be stably assembled with the outdoor lamp to stably support and position the outdoor lamp. The bracket 1 is provided with at least two circular fixing holes 13 and at least two oval adjusting holes 14. The first screw passes through the circular fixing hole 13 and is screwed to the outer shell of the outdoor lamp. The second screw passes through the circular fixing hole 13 and is screwed to the outer shell of the outdoor lamp.

[0030] The upper end of the plastic base 4 is also provided with a net tail 41, which wraps around the insulation layer 31 of all wires 3 to enhance the flexibility of the wires, thereby preventing the wires 3 from breaking due to swaying or pulling, and improving the service life of the product.

[0031] The plug 5 includes a plastic shell 51 and a plurality of terminals inserted and fixed inside the plastic shell 51. The plastic shell 51 is provided with a fourth wire hole 511 through which the power supply wire 3 passes. A silicone sleeve 7 is fitted on the wire 3 to form a sealed assembly. The silicone sleeve 7 is embedded in the wire hole and forms a sealed assembly with the inner wall of the fourth wire hole 511, which can further improve the waterproof performance and achieve the effect of preventing rain.

[0032] Specifically, the silicone sleeve 7 has a central hole 71 through which the power supply wire 3 passes. The diameter of the central hole 71 is smaller than the outer diameter of the wire 3, so that the insulation layer 31 of the wire 3 and the central hole 71 form an interference fit and are fastened together to achieve a sealed assembly effect, which has a better waterproof effect. At the same time, it can increase the friction, so that the wire 3 can be installed more stably in the fourth wire hole 511 of the plastic shell 51. The lower end of the central hole 71 has a flared guide opening 72, which facilitates the wire 3 to pass through the central hole 71 of the silicone sleeve 7 and improves the assembly efficiency.

[0033] The lower end of the silicone sleeve 7 is provided with several spaced sealing protrusions 73. These sealing protrusions 73 are pressed and sealed against the inner wall of the fourth wire hole 511, resulting in better waterproofing and increased friction. This allows the wire 3 to be installed more stably in the fourth wire hole 511 of the plastic shell 51. The upper end of the silicone sleeve 7 is provided with a buckle 74, which engages with the buckle groove on the inner wall of the fourth wire hole 511 to prevent detachment, thereby ensuring that the wire 3 is installed more stably in the fourth wire hole 511 of the plastic shell 51.

[0034] In summary, this utility model uses a bracket 1 to fix the outdoor light fixture, which enhances the stability of the fixed assembly with the outdoor light fixture. The main body 300 of the wire harness is inserted and fixed to the limiting slot 21 of the support base 2 through the plastic seat 4 at the lower part of the wire 3, forming a one-time fixation. The lower end of the wire 3 passes through the first wire hole 22 from top to bottom, then bends to fit against the lower end of the bracket 1, and then bends from bottom to top and passes through the second wire hole 11 to be exposed at the upper end of the bracket 1. In this way, the wire 3 passes through the first wire hole 22 and the second wire hole 11 respectively. The bracket 1 is bent to achieve secondary fixation. Finally, the conductor 32 at the lower end of the wire 3 is threaded and soldered to the pads of the PCB board of the outdoor lighting fixture, thus achieving tertiary fixation and providing strong tensile strength. This ensures a stable assembly between the wire harness body 300, the bracket 1, and the outdoor lighting fixture, preventing detachment and guaranteeing product quality. It also ensures stable electrical conductivity between the wire 3 and the PCB board of the outdoor lighting fixture, guaranteeing normal operation and extending the lifespan of the lighting fixture. Furthermore, the bracket 1 is equipped with a waterproof gasket 6. The insulation layer 31 at the lower end of the wire 3 passes through the third through-hole 61 on the waterproof gasket 6, forming a sealed contact. The conductor 32 at the lower end of the wire 3 protrudes upwards and is exposed on the upper surface of the waterproof gasket 6, achieving waterproof performance and ensuring normal operation of the lighting fixture.
