Description

Technical Field

[0001] The utility model belongs to the technical field of packaging, and in particular relates to an LED flat-leg bracket structure. Background Art

[0002] In the field of electronic equipment, substrates are important components that connect and support various electronic components. Their design and manufacturing technology has always been the focus of the industry.

[0003] Traditional substrate designs often focus only on basic electrical connection functions, while ignoring ease of use, stability, and reliability in practical applications. Pins are the primary way to connect the substrate to external circuits, and their design and layout directly affect the performance and stability of the entire electronic device. However, in traditional substrate designs, pins are often directly exposed to the outside and are easily interfered with and damaged by the external environment, thus affecting the stability of the electrical connection.

[0004] Therefore, in response to the above problems, the present invention proposes a new substrate design method. Utility Model Content

[0005] The purpose of the present invention is to provide an LED flat-leg bracket structure to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] An LED flat-leg bracket structure, comprising:

[0008] A substrate, wherein a pad is provided inside the substrate, pins are provided on both sides of the pad, and the pins extend to the outside of the substrate;

[0009] A cup body is provided on one side of the substrate. The substrate is smaller than the cup body. The pins are located below the cup body and do not contact the cup body and are flush with the bottom of the substrate.

[0010] Preferably, a cup cavity is provided through the interior of the cup body, and an inner groove is provided on the edge of the cup cavity.

[0011] Preferably, an IC chip and an LED chip are arranged on the pad.

[0012] Preferably, a stepped groove is provided at the end of the pin.

[0013] Preferably, the surface of the pin is covered with a metallized protective layer.

[0014] Preferably, a fool-proof mark is provided at the bottom of the substrate, and the fool-proof mark is at least one of a rounded corner / a right angle and a "T / ▲" shape.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The cup design can provide additional protection and packaging for the electronic components on the substrate. At the same time, the pins are located under the cup but do not touch it, ensuring that the connection between the pins and the external circuit is not disturbed. The flat bottom also makes it more convenient and flat to install.

[0017] (2) The provision of the stepped groove helps to improve the contact stability and firmness between the pin and the external connector, thereby improving the reliability of the electrical connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] A substrate 1 is provided with a pad 2 inside the substrate 1, and pins 4 are provided on both sides of the pad 2. The pins 4 extend to the outside of the substrate 1, and the number of pins 4 is four or six;

[0027] A cup body 3 is provided on one side of the substrate 1 . The substrate 1 is smaller than the cup body 3 . The pins 4 are located below the cup body 3 and do not contact the cup body 3 . The pins 4 are flush with the bottom of the substrate 1 .

[0028] In one embodiment of the present invention, a cup cavity 5 is formed through the interior of the cup body 3 , and an inner groove 6 is formed on the edge of the cup cavity 5 .

[0029] In one embodiment of the present invention, an IC chip 7 and an LED chip 8 are disposed on the pad 2 .

[0030] In one embodiment of the present invention, a stepped groove is provided at the end of the pin 4 .
