Description

Technical Field

[0001] The utility model relates to the field of LED brackets, in particular to a high-density LED bracket. Background Art

[0002] For the existing LED bracket structure, during stamping design, a certain width of connecting ribs need to be reserved for the connection between the pad and the guide rail on the LED bracket. After the LED bracket is injection molded, the connecting ribs are cut off to separate the pad and the guide rail, and then the pad is bent to form a single LED bracket. The setting of the connecting ribs not only takes up space, which is not conducive to the compact arrangement of the LED bracket, but also can only be treated as waste after the connecting ribs are cut off, which is wasteful and not conducive to cost reduction. With the increasing maturity of chipless cutting technology, it is necessary to develop a high-density LED bracket that can be used with chipless cutting technology to reduce the waste rate in the LED bracket manufacturing process to solve the above problems.

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] like Figure 1 As shown, an existing LED bracket structure is provided between two groups of plastic brackets 02 in a group of cavity areas 03, and a longitudinal guide rail 05 is provided. The longitudinal guide rail 05 is connected to the pads on both sides through connecting ribs 06. When punching and cutting the pads, the entire connecting rib 06 needs to be removed. The LED bracket at the side position also needs to remove the connecting rib 06 to separate the pads from the substrate frame 11. The scrap rate is relatively high, and because the pads are separated by the connecting ribs 06 and the longitudinal guide rail 05, the arrangement density of the LED bracket is very low.

[0020] like Figure 2As shown, the design provides a high-density LED bracket, including a metal substrate 01 and a plastic bracket 02, the metal substrate 01 includes an integrally arranged substrate frame 11, a left solder pad 12, a right solder pad 13 and a cut-off rib 14, the substrate frame 11 is provided with a plurality of groups of cavity areas 03 arranged in a matrix, the left solder pad 12 and the right solder pad 13 are alternately arranged in a plurality of groups in the horizontal direction in a group of cavity areas 03, the plastic bracket 02 is fixed to the right end of the left solder pad 12 and the left end of the right solder pad 13, the left end of the leftmost group of left solder pads 12 is connected to the substrate frame 11, the right end of the rightmost group of right solder pads 13 is connected to the substrate frame 11, the right end of the adjacent right solder pad 13 is connected to the left end of the left solder pad 12 and the connection position is the cut-off portion 04, and the cut-off portion 04 is connected to the substrate frame 11 through the longitudinally arranged cut-off rib 14.

[0021] By directly connecting the left pad 12 and the right pad 13 of two adjacent groups of LED brackets, the previous method of setting a guide rail and a connecting rib 06 in the middle is abolished, and the cutting rib 14 is used to connect with the cutting part 04 from the longitudinal direction, so that the arrangement density of the LED bracket is higher. When cutting, the chip-free cutting technology can be directly used to cut the cutting rib 14 and cut the cutting part 04 along the cutting line 07, which greatly reduces the waste of cutting. For the LED bracket at the edge position, it is cut along the cutting line 07 without generating waste. The advantage of this design is that it can not only improve the arrangement density of the LED bracket, but also reduce the waste rate and manufacturing cost.

[0022] In a group of cavity areas 03, the left pads 12 and the right pads 13 are arranged in two rows along the longitudinal direction, and the cutting parts 04 are arranged in two rows. The metal substrate 01 also includes a middle rib 15, and the upper and lower ends of the middle rib 15 are respectively connected to the two rows of cutting parts 04. The middle rib 15 makes the positions of the pads on the upper and lower sides more stable, and the cutting accuracy is higher during the cutting process.

[0023] The cut rib 14 can be connected to both the left end of the left pad 12 and the right end of the right pad 13, that is, the cutting line 07 and the cut rib 14 are at the same longitudinal position. The cut rib 14 can also be connected to the left end of the left pad 12 alone, or to the right end of the right pad 13 alone.

[0024] like Figures 2 to 4 As shown, within a group of cavity areas 03, the plastic brackets 02, the left solder pads 12 and the right solder pads 13 can be arranged in two, three or four groups, or even more, in the horizontal direction to further improve the arrangement density of the LED brackets.

[0025] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
