Description

Technical Field

[0001] The utility model relates to the technical field of LEDs, in particular to a bracket with positive and negative stretching and bending functions. Background Art

[0002] With the increasing development and maturity of LED technology, LEDs have become a new type of light source and are widely used in various fields. The LED bracket is the base of the LED lamp bead before it is packaged. On the basis of the LED bracket, the chip is fixed, the positive and negative electrodes are soldered, and then the encapsulation adhesive is used to form the whole package. To achieve a more concentrated lighting effect, a focusing bracket with a cup is often used.

[0003] However, the pads inside existing brackets are often stretched in only one direction, which makes them easy to shake inside the bracket. Moreover, the pads are all located on the same plane, and there is no barrier in the middle of the chip, which makes internal short circuits prone to occur. At the same time, connecting the chip and the pads requires more gold wire. Utility Model Content

[0004] The purpose of the utility model is to provide a bracket with two-way stretching and bending, and the pad structure of the positive and negative stretching makes the pad more stable in the bracket and not easy to shake. In addition, by arranging short pads and long pads of different heights inside and cooperating with divided small cups and large cups, the chip is separated to prevent internal short circuit. At the same time, the gold wire connecting the chip and the pad can be saved, thereby solving the problems raised by the above technical background.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a bracket with two-way stretching and bending, comprising: a bracket body, a reflective cup is opened at the top of the bracket body, and multiple conductive terminals are set at the bottom ends of both sides of the bracket body, the top of the conductive terminal is connected to the connecting bracket through forward stretching, and the connecting bracket penetrates the bracket body, the top of the connecting bracket is connected to a short welding pad, and multiple short welding pads are evenly arranged on both sides of the bottom end of the reflective cup, a short welding pad on one side of the bracket body is connected to a long welding pad through reverse stretching, and the long welding pad is arranged in the middle of the bottom end of the reflective cup, a partition is set in the reflective cup, and two partition cups are opened in the middle of the partition.

[0006] Preferably, the mouth of the reflective cup is located at the top of the bracket body, and the reflective cup has a trumpet-shaped structure.

[0007] Preferably, an identification groove is provided at a corner of the top end of the bracket body.

[0008] Preferably, a plurality of terminal grooves are evenly formed on both sides of the bottom end of the bracket body, and conductive terminals are snapped into the terminal grooves.

[0009] Preferably, limiting grooves are provided on the outer sides of the short pads on both sides of the bracket body and on both sides of the long pads.

[0010] Preferably, a plurality of pad grooves are provided on both sides of the barrier, and short pads are snapped into the pad grooves.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] Connect the short pad, the connection bracket and the conductive terminal by positive stretching, and connect the short pad and the long pad by reverse stretching, so that the position of the pad is more stable;

[0013] A barrier cup is opened in the middle of the barrier to divide the long pad so that the chip with the long pad is placed in two barrier cups respectively. This can separate the chips mounted on the long pad to prevent internal short circuits and save pads and gold wires connecting the chips.

[0014] The bracket with two positive and negative stretching bends makes the pad more stable in the bracket and less likely to shake through the positive and negative stretching pad structure. In addition, by setting short pads and long pads of different heights inside and combining them with divided small cups and large cups, the chip is separated to prevent internal short circuits, while saving gold wires connecting the chip and the pad.
