Description

Technical Field

[0001] The utility model relates to the field of a lead frame of a light emitting diode, in particular to a lead frame of a light emitting diode. Background Art

[0002] LED lead frames are usually made of materials with good electrical conductivity, such as metals or alloys. Common materials include silver, copper, gold, etc., to ensure good electrical conductivity and corrosion resistance. Structure: LED lead frames usually present a planar structure, including two or more wires for connecting the positive and negative poles of the LED chip. The design and arrangement of the lead frame can vary according to the packaging form and installation requirements of the LED chip. Manufacturing process: The manufacture of LED lead frames usually adopts precision metal processing technology, including cutting, stamping, bending and other steps to ensure the precise size and good electrical conductivity of the wire. Welding: The connection between the LED lead frame and the LED chip is usually completed by welding. Solder or other welding materials are used to connect the lead frame to the metal lead of the LED chip to achieve electrical connection. Thermal management: In some high-power LED applications, the design of the LED lead frame also takes into account thermal management factors. By optimizing the structure and materials of the lead frame, the heat dissipation performance of the LED chip is improved to ensure the stable operation of the LED.

[0003] Some existing light emitting diode lead frames can usually falsely raise the lead through a simple hanging mechanism, which also makes the lead no longer messily placed as before and makes the lead more neat.

[0004] However, the hanging mechanism cannot well fix the interface between the wire and the light-emitting diode, and it does not have the function of sealing the bracket mechanism and combining multiple bracket mechanisms. This makes the operation more troublesome when more diodes are needed. Therefore, a wire rack for light-emitting diodes is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a lead frame for light emitting diodes, aiming to improve the problems in the prior art that the interface between the wire and the light emitting diode cannot be fixed, the sealing degree of the entire lead frame is insufficient, and multiple lead frames cannot be combined.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: the lead frame of the light-emitting diode includes a glass cover, the bottom end of the glass cover is fixedly connected to a glass base, a rubber ring is arranged on the inner side of the glass base, a fixing plate is fixedly connected to the inner side of the rubber ring, the fixing plate and the glass base are threadedly connected by screws, and a plurality of wire racking mechanisms are evenly and equidistantly arranged on the fixing plate.

[0007] The glass cover and rubber ring ensure the sealing of the device. The purpose of the glass base is to fix the glass on the fixing plate to ensure the stability of the device. The fixing plate is connected to the glass base through threads to fix the glass. There are rubber rings on the inside of the glass base and the outside of the fixing plate. The glass base is threadedly connected to the rubber ring through screws to ensure that it can be disassembled for easy replacement and maintenance. The wiring mechanism is fixed on the fixing plate to ensure the stability of the wiring mechanism and reduce the vibration at the interface between the wire and the diode.

[0008] As a further description of the above technical solution: a lower base plate is provided at the bottom end of the wiring mechanism, wire entry and exit holes are provided at both ends of the lower base plate, a wire management groove is fixedly connected to the middle part of the upper end of the lower base plate, a plurality of wire holes are provided on both sides of the wire management groove, a partition plate is fixedly connected to the middle part of the upper end of the wire management groove, and rubber sealing rings are provided on the wire entry and exit holes.

[0009] The lower base plate may be provided with wire entry and exit holes, which ensure that the wires can enter and be led out of the lower base plate. The wire management groove ensures that the wires can be placed inside, and the wire holes ensure that the wires can enter the groove. The rubber sealing ring can ensure the sealing of the device, and the sealing can delay corrosion at the interface between the wires and the diode. The partition can isolate the wires on both sides to ensure their neatness.

[0010] As a further description of the above technical solution: the wire rack mechanism includes a wire rack drum, an upper portion of one side of the wire rack drum is threadedly connected with a screw, and one end of the screw is fixedly connected with a rubber pad.

[0011] The diameter of the wire drum is smaller than that of the lower wire drum. Tightening the screws can squeeze it downward to fix the interface between the wire and the light-emitting diode to ensure that they will not separate from each other due to severe shaking. The rubber pad can ensure that the interface is not damaged by direct contact with the screws.

[0012] As a further description of the above technical solution: a line fixing position is fixedly connected to an upper portion of one side of the wire rack, and a line distribution plate is fixedly connected to a middle portion of one end of the line fixing position.

[0013] The wire fixing position ensures that the extrusion of the screw is effective on the interface between the wire and the light-emitting diode, and the distribution board can separate the positive and negative poles without affecting each other.

[0014] As a further description of the above technical solution: a sliding plate is fixedly connected to the lower middle side of both ends of the wire drum, and a lower wire drum is slidably connected to both sides of the sliding plate, and sliding grooves are provided on both sides of the lower wire drum.

[0015] The slide can ensure that the wire drum can slide smoothly on the lower wire drum without relative rotation, thereby ensuring that the light emitting diode can be stably connected to the wire.

[0016] As a further description of the above technical solution: a notch is provided on one side of the bottom end of the lower wire drum, and a middle side of the lower wire drum is fixedly connected to a fixing plate.

[0017] The notch can ensure that the wire can be led out and enter the wire management slot through the wire hole. One side of the middle part of the lower wire drum is fixedly connected to the fixing plate to ensure the stability of the device.

[0018] As a further description of the above technical solution: the outer wall of the wire drum is slidably connected to the inner wall of the lower wire drum, and the notch is opposite to the wire hole.

[0019] The outer wall of the wire drum is slidably connected to the inner wall of the lower wire drum, which ensures that the wire drum can be removed to pass the wire first and then fill the lower wire drum.

[0020] The utility model has the following beneficial effects:

[0021] 1. In the utility model, the glass cover, the rubber ring, and the rubber sealing ring structure are closely attached to each other, so that the sealing performance of the device is good, and the aging effect of the interface between the wire and the light-emitting diode is delayed.

[0022] 2. In the utility model, with the cooperation of the screws, wire drum, rubber pads and wire fixing positions in the wire-hanging mechanism, after the wires and light-emitting diodes are connected, the interfaces will not be separated from each other due to severe shaking, so as to solve the accidents caused by the separation of the interfaces.

[0023] 3. In the utility model, the cooperation of the bottom plate, the rubber sealing ring and the wire management trough ensures that the device can be spliced, which solves the problem that the device cannot splice the wire rack when multiple light-emitting diodes are required to work, and solves the problem that the previous device cannot meet the needs of multiple light-emitting diodes working and cannot splice the wire rack.
