[0002] LED lights are widely used, and the light source component is the core component of LEDs. The light source component generally includes a bracket and an integrated light source module. The bracket is fixed with power terminals, which are generally connected to the light source module in two ways. Currently, the main method is soldering, which is relatively complex to assemble and has low assembly efficiency. Another method is to use spring contacts, but this method requires inserting the spring contacts into the bracket first, and there is a risk of loosening at the connection point. Loosening can sometimes cause poor contact, and the reliability needs to be further improved. Utility Model Content

[0003] To overcome the shortcomings and problems of the existing technology, this utility model provides a light source assembly with pre-embedded terminals. The contact piece is pre-embedded in the bracket, which does not require additional assembly and will not loosen, thus ensuring high reliability. It also has a positioning detection hole to facilitate the positioning of the contact piece assembly and to detect the power supply status of the contact piece assembly without disassembly.

[0004] This utility model is achieved through the following technical solution:

[0005] A light source assembly with pre-embedded terminals includes a bracket.

Detailed Implementation

[0018] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-5 As shown, a light source assembly with a pre-embedded terminal includes a bracket 1. The bottom surface of the bracket 1 is provided with a mounting groove 11 for mounting an integrated light source module 3. A through hole 12 for light to pass through is provided in the middle of the mounting groove 11, and the light emitted by the integrated light source module 3 is diffused out through the through hole 12.

[0020] An electrical contact assembly 2 is embedded inside the bracket 1. The electrical contact assembly 2 has an electrical terminal 201 exposed in the mounting groove 11 and a connecting portion 202 exposed on the outer surface of the bracket 1. An integrated light source module 3 is housed within the mounting groove 11. The integrated light source module 3 has electrical contacts 31 that conduct electricity to the electrical terminals 201. The connecting portion 202 is used to connect a power source. The electrical terminals 201 and the electrical contacts 31 conduct electricity, allowing the power source to be electrically connected to the integrated light source module 3. The integrated light source module 3 includes a circuit board, on which an LED light source is packaged. The electrical contact assembly 2 includes two conductive contact pieces 21, which are integrally injection molded with the bracket 1. Each conductive contact piece 21 has an electrical terminal 201, and each terminal extends out of the bracket 1 at one end to form a connecting portion 202. The two connecting portions 202 are used to connect the positive and negative terminals of the power source, respectively. The electrical terminal 201 is cone-shaped and protrudes from the surface of the conductive piece 21. This structure makes the contact between the electrical terminal 201 and the electrical contact 31 more reliable. The mounting groove 11 is square, with the hole 12 located at the center of the mounting groove 11, and the two electrical terminals 201 are arranged at opposite corners of the mounting groove 11.

[0021] The mounting groove 11 has a latch assembly 4 on its side for fixing the integrated light source module 3. The latch assembly 4 can stably fix the integrated light source module 3 in the mounting groove 11, so that the electrical contact 31 and the electrical terminal 21 can reliably make contact and conduct electricity. The latch assembly 4 includes a fixing latch 41 and a plug-in latch 42. The fixing latch 41 is located on one side of the mounting groove 11. The mounting groove 11 has a plug-in groove 13 on the side opposite to the fixing latch 41. The plug-in latch 42 is plugged into and fixed in the plug-in groove 13. The fixing latch 41 and the plug-in latch 42 abut against the opposite two sides of the integrated light source module 3, thereby fixing the integrated light source module 3. The plug-in buckle 42 is provided with a protrusion 421 with a tapered surface. A strip hole 422 is provided on one side of the protrusion 421. The shape of the protrusion 421 can prevent the integrated light source module 3 from loosening. The strip hole 422 can increase the elasticity of the protrusion 421, so that the protrusion 421 has better elasticity when it abuts against the side of the integrated light source module 3.

[0022] The bracket 1 has several positioning detection holes 14 on both sides, each extending from the surface of the bracket 1 to the contact plate group 2. Each of the two conductive plates 21 has several corresponding positioning detection holes 14, distributed on both sides of the bracket 1. During injection molding, the positioning detection holes 14 are used to position the conductive plates 21, and later, the energization status of the contact plate group 2 can also be detected through the positioning detection holes 14.

[0023] The working process of this utility model is as follows: When producing the bracket 1, the two conductive plates 21 are embedded in the bracket 1 and integrally injection molded. During injection molding, the conductive plates 21 are positioned through the positioning detection hole 14. During assembly, the integrated light source module 3 is placed into the mounting groove 11 and pressed tightly. The power terminal 201 contacts the power contact 31. Then, the plug-in buckle 42 is inserted into the plug-in slot 13, thereby fixing the integrated light source module 3. At this time, the light source assembly is assembled, which is quick, convenient and highly reliable. In later use, there is no need to disassemble it. The power supply status of the conductive plates 21 can be detected through the positioning detection hole 14.

[0024] The above embodiments are preferred implementations of this utility model and are not intended to limit this utility model. Any obvious substitutions are within the protection scope of this utility model without departing from its inventive concept.
