Description

Technical Field

[0001] This utility model relates to the field of PCB boards, and more particularly to a PCB board for LED lighting fixtures. Background Technology

[0002] The PCB board of an LED lamp is a circuit board used to install and connect LED chips. Its core function is to provide electrical connection, heat dissipation support and mechanical fixation to ensure that the LED emits light efficiently and stably.

[0003] Utility model CN202907330U discloses a PCB circuit board for LED lighting fixtures. The key technical points are: a copper foil structure, consisting of a first heat-dissipating copper foil, a second heat-dissipating copper foil, and a control copper foil, is designed on the circuit board in an I-shape or other shapes. This utility model utilizes more copper foil in contact with air or other heat dissipation media, significantly increasing the heat dissipation area and greatly improving the heat dissipation effect. This effectively reduces the temperature difference between the chip junction temperature and the lighting fixture heat sink. Even when the lighting fixture heat sink temperature is high, the junction temperature of the LED chip remains within a reasonable range, thus reducing the amount of heat dissipation material required. The improved heat dissipation capacity facilitates the miniaturization of heat dissipation devices, thereby saving costs. If an aluminum substrate is used, it not only improves the heat dissipation capacity to the air but also enhances the heat dissipation capacity of the LED chip to the aluminum plate below.

[0004] Regarding the above-mentioned issues, the following technical defects were found: Before use, the PCB circuit board needs to be connected to the LED bulb with wires. However, the wire layout of the PCB board of traditional LED lamps is messy and the wires are easy to get tangled. Therefore, it is inconvenient for personnel to inspect the wires of the PCB circuit board, which affects the reliability of the circuit.

[0005] Therefore, it is necessary to provide a PCB board for LED lighting fixtures to solve the problems of messy wire layout, easy tangling, and inconvenient maintenance. Utility Model Content

The connecting plate drives the limiting strip to squeeze the wires, thereby fixing the wires firmly and preventing the wires from shaking and causing unstable connection with the PCB circuit board, thus improving the connection stability between the wires and the PCB circuit board.

[0011] Preferably, a guide rod is slidably passed through the surface of the connecting plate, and the upper end of the guide rod is fixedly connected to the lower surface of the wire harness plate.

[0012] The effect achieved by the above components is that when the lead screw rotates to drive the connecting plate to move, the guide rod can guide the movement of the connecting plate, thereby preventing the connecting plate from rotating and deviating during the movement process.

[0013] Preferably, a rubber pad is fixedly connected to the inner wall of the limiting cloth strip, and the rubber pad abuts against the arc surface of the wire.

[0014] The effect achieved by the above components is that the rubber pad can increase the friction inside the limiting strip, thereby improving the limiting effect of the limiting strip on the wire.

[0015] Preferably, a knob is fixedly connected to the lower end of the lead screw, and the knob has a number of anti-slip textures evenly distributed on its arc surface.

[0016] The effect achieved by the above components is that the operator can rotate the knob with the help of the anti-slip texture, and the knob drives the lead screw to rotate, thus achieving the effect of convenient control of the lead screw rotation.

[0017] Preferably, a plurality of connecting ropes are fixedly connected to the upper surface of the cable tray, and an elastic sleeve is fixedly connected to one end of the rope away from the cable tray.

[0018] The effect achieved by the above components is that after the wires are bound with the limiting cloth strips, the elastic sleeves can be used to tie the wires with the same direction together, thereby making the arrangement of the wires more orderly.

[0019] Preferably, the PCB circuit board has a side impact pad fixedly connected to it, and the impact pad is a silicone pad.

[0020] The effect achieved by the above components is as follows: by setting silicone anti-collision pads on the side of the above PCB circuit board, the silicone pads have good elasticity, are resistant to high and low temperatures, and are insulating and short-circuit resistant, which can effectively absorb impact and protect the PCB edges from mechanical damage.

By providing silicone anti-collision pads 5 on the side of the PCB circuit board 1, the silicone pads have good elasticity, are resistant to high and low temperatures, and provide insulation and short-circuit protection, effectively absorbing impacts and protecting the PCB edges from mechanical damage.

[0031] Among them, a wire harness assembly 3 is provided on one side of the PCB circuit board 1.

[0032] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The cable harness assembly 3 includes two mounting rods 301. One end of each mounting rod 301 is fixedly connected to one side of the PCB circuit board 1. A cable harness plate 302 is fixedly connected to the ends of the two mounting rods 301 away from the PCB circuit board 1. Several cable harness cavities 303 are formed on the upper surface of the cable harness plate 302. Several limiting rings 304 are fixedly connected to the upper surface of the cable harness plate 302 at positions corresponding to the cable harness cavities 303. The limiting rings 304 have a U-shaped cross-section. The wires 4 are located within the space formed by the limiting rings 304 and the cable harness cavities 303. By setting up the cable harness assembly 3, the wires 4 connected to the PCB circuit board 1 can be neatly arranged, preventing the wires 4 from becoming tangled, facilitating the maintenance of the wires 4, and thus improving circuit reliability.

[0033] A limiting strip 305 is slidably inserted through the inner wall of the cable bundle cavity 303. The limiting strip 305 has a "U" shaped cross-section and is sleeved over the outside of the wire 4. A connecting plate 306 is fixedly connected to the lower surface of the limiting strip 305. A lead screw 307 is threaded through the surface of the connecting plate 306, and the upper end of the lead screw 307 is fixedly connected to the lower surface of the cable bundle plate 302. When the wire 4 on the PCB circuit board 1 passes through the space formed by the limiting ring 304 and the cable bundle cavity 303, the lead screw 307 is rotated to drive the connecting plate 306, causing the connecting plate 306 to move away from the cable bundle plate 302. The connecting plate 306 drives the limiting strip 305 to compress the wire 4, thereby fixing the wire 4 firmly and preventing the wire 4 from shaking and causing unstable connection with the PCB circuit board 1, thus improving the connection stability between the wire 4 and the PCB circuit board 1. A guide rod 308 is slidably inserted through the surface of the connecting plate 306, and the upper end of the guide rod 308 is fixedly connected to the lower surface of the cable tray 302. When the lead screw 307 rotates to drive the connecting plate 306 to move, the guide rod 308 can guide the movement of the connecting plate 306, thereby preventing rotational deviation during the movement of the connecting plate 306. A rubber pad 310 is fixedly connected to the inner wall of the limiting strip 305, and the rubber pad 310 abuts against the arc surface of the wire 4. The rubber pad 310 can increase the friction inside the limiting strip 305, thereby improving the limiting effect of the limiting strip 305 on the wire 4. A knob 309 is fixedly connected to the lower end of the lead screw 307, and the arc surface of the knob 309 is evenly provided with several anti-slip textures. Personnel can rotate the knob 309 with the help of the anti-slip textures, and the knob 309 drives the lead screw 307 to rotate, achieving the effect of conveniently controlling the rotation of the lead screw 307.

[0034] Several connecting ropes 311 are fixedly connected to the upper surface of the cable management plate 302, with elastic sleeves 312 fixedly connected to one end away from the cable management plate 302. After the wires 4 are bound with the limiting cloth strip 305, the elastic sleeves 312 can be used to bundle the wires 4 with the same direction together, thereby making the arrangement of the wires 4 more orderly. The connecting ropes 311 can prevent the elastic sleeves 312 from being lost.

[0035] The working principle of the PCB board for LED lamps provided by this utility model is as follows: When in use, the PCB board 1 is connected to the LED bulb via wires 4. When the wire harness assembly 3 is needed to position the wires 4, several wires 4 of the PCB board 1 are sequentially passed through the space formed by the limiting ring 304 and the wire harness cavity 303, so that the wires 4 are neatly arranged and avoid tangling during use. After the wires 4 on the PCB board 1 pass through the space formed by the limiting ring 304 and the wire harness cavity 303, the knob 309 is rotated with the help of the anti-slip texture. The knob 309 drives the lead screw 307 to rotate, and the lead screw 307 drives the connecting plate 306, causing the connecting plate 306 to move away from the wire harness plate 302. The connecting plate 306 drives the limiting strip. 305. The limiting strip 305 drives the rubber pad 310 to compress the wire 4, thereby fixing the wire 4 firmly and preventing it from shaking and causing unstable connection with the PCB circuit board 1. This improves the connection stability between the wire 4 and the PCB circuit board 1. When the lead screw 307 rotates to drive the connecting plate 306 to move, the guide rod 308 can guide the movement of the connecting plate 306, thereby preventing rotational deviation during the movement of the connecting plate 306. The rubber pad 310 can increase the internal friction of the limiting strip 305, thereby improving the limiting effect of the limiting strip 305 on the wire 4. After using the limiting strip 305 to bind the wire 4, the elastic sleeve 312 can be used to tie the wires 4 with the same direction together, thereby making the arrangement of the wires 4 more orderly.
