Description

Technical Field

[0001] This utility model relates to the field of diode technology, and in particular to a light-emitting diode assembly with adjustable pins. Background Technology

[0002] Light-emitting diodes (LEDs), as common photoelectric conversion devices, are widely used in lighting, displays, indicators, and many other fields. Traditional LED packaging structures typically consist of epoxy resin encapsulating the internal light-emitting chip and electrode connection structure, with two leads at the bottom for external electrical connections. However, in existing technologies, the two metal leads of LED components are mostly fixed structures, with non-adjustable mounting lengths and a lack of flexible adjustment capabilities.

[0003] In actual use and installation, if the pins are broken or deformed by force, they usually cannot be effectively repaired or replaced. Especially in some cases where there are specific requirements for pin length, fixed-length pins may not meet the installation requirements, thus causing the entire LED assembly to be scrapped. In addition, fixed pin structures have certain risks during transportation and assembly, and are easily damaged by external forces, affecting the electrical performance and service life of the device.

[0004] To address this issue, we propose a pin-adjustable LED assembly. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a light-emitting diode assembly with adjustable pins.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a light-emitting diode assembly with adjustable pins, comprising an epoxy resin shell, pins and spring cables, wherein a cathode block and an anode block are respectively disposed inside the epoxy resin shell, and a sliding cavity is formed inside the cathode block and the anode block;

[0007] The two pins are respectively telescopically mounted on the sliding cavity and connected to the cathode block and anode block via spring cables.

[0008] Preferably, a reflector bowl is fixedly disposed on the upper surface of the cathode block, and an LED chip is disposed inside the reflector bowl.

[0009] Preferably, a gold wire is fixedly disposed on the anode block, the other end of the gold wire is connected to the input end of the LED chip, and the output end of the LED chip is connected to the cathode block.

[0010] Preferably, a rubber seat is fixedly provided at the bottom of the inner wall of the sliding cavity, and the pin is slidably connected to the rubber seat.

[0011] Preferably, an upper plug is fixedly provided on the upper outer wall of the pin, and the outer wall of the upper plug is slidably connected to the inner wall of the sliding cavity. The upper plug is made of rubber.

[0012] Preferably, one end of the two spring cables is fixed to the top of the two pins, and the other end of the two spring cables is fixed to the cathode block and the anode block, respectively.

[0013] Preferably, the lower end of the pin has a mounting hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model features retractable and adjustable pins: by setting a sliding cavity structure inside the cathode block and anode block, the pins can retract and move within the sliding cavity, thereby flexibly adjusting the exposed length of the pins according to installation requirements and significantly improving assembly flexibility.

[0016] Increase sliding friction to prevent loosening and falling off: By providing a rubber upper plug on the pin and sliding it in conjunction with the inner wall of the sliding cavity, appropriate damping is formed during the adjustment process to prevent the pin from loosening or misaligning under non-human operation, thereby improving the stability of use;

[0017] Effective isolation of electrode contact enhances safety: A rubber seat structure is set at the bottom of the sliding cavity to keep the pins insulated sliding connection with the cathode block and anode block, avoiding accidental contact that could lead to short circuits or damage;

[0018] Flexible electrical connection: Spring cables are used to connect the pins and the electrode blocks. While ensuring conductivity, the movable pin structure adapts to the electrical connection, improving the overall shock resistance and reliability. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figures 1-4 As shown, the present invention proposes a light-emitting diode assembly with adjustable pins, including an epoxy resin shell 1, pins 2, mounting holes 3, cathode block 4, anode block 5, LED chip 6, reflector bowl 7, gold wire 8, spring cable 9, upper plug block 10, sliding cavity 11, and rubber seat 12.

[0027] The epoxy resin shell 1 is used to encapsulate the internal structure, and has good light transmission performance and structural protection function. The epoxy resin shell 1 is made of transparent material with high refractive index and low impurity content, and is formed in one step through injection molding process. This not only improves the uniformity of light emission, but also effectively suppresses color distortion.

[0028] Both the cathode block 4 and the anode block 5 are located inside the epoxy resin shell 1, and each of the cathode block 4 and the anode block 5 is provided with a sliding cavity 11. The axial dimension of the sliding cavity 11 matches the structural dimension of the pin 2 to ensure smooth sliding and avoid shaking or poor contact.

[0029] Example 2

[0030] like Figures 1-4 As shown, the present invention proposes a pin-adjustable light-emitting diode assembly, which, compared to Embodiment 1, further includes:

[0031] Two pins 2 are respectively set in the sliding cavity 11 by sliding and are slidably connected to the rubber seat 12. The rubber seat 12 is fixed at the bottom of the sliding cavity 11 to provide elastic support and damping effect, preventing the pins 2 from sliding freely or loosening. The rubber seat 12 is made of highly elastic insulating material, which has good recovery performance and stable contact pressure, and can maintain conductivity stability and structural compactness for a long time.

[0032] The upper end of pin 2 is fixedly connected to the upper plug 10. The upper plug 10 is made of rubber and fits tightly with the inner wall of the sliding cavity 11 to increase the sliding resistance, so that pin 2 can maintain the required position during the adjustment process and avoid displacement.

[0033] One end of each of the two spring cables 9 is fixed to the top of the two pins 2, and the other end is connected to the cathode block 4 and the anode block 5 respectively, forming a flexible electrical connection structure to ensure that the electrical conduction is not affected during the extension and retraction adjustment of the pins 2. The spring cables 9 are made of silver-plated copper core and have excellent electrical conductivity and tensile strength, ensuring that they can maintain stable conduction under long-term frequent stretching.

[0034] A reflector bowl 7 is installed on the upper surface of the cathode block 4. An LED chip 6 is set inside the reflector bowl 7 to focus the emitted light and improve the light efficiency. The input end of the LED chip 6 is connected to the anode block 5 through a gold wire 8, and the output end is electrically connected to the cathode block 4 to complete the light-emitting circuit. The inner wall of the reflector bowl 7 is treated with optical mirror aluminum plating, which can achieve efficient light reflection and significantly enhance the uniformity and directionality of light intensity distribution.

[0035] The lower end of pin 2 is provided with mounting hole 3, which facilitates quick connection and fixation of pin 2 with external circuits or structures, improves the assembly compatibility of components, and the mounting hole 3 can be adapted to other components by means of snap-fit, thread or welding to adapt to different installation scenarios.

[0036] This LED assembly has a reasonable structure. The adjustable length is achieved through the cooperation between pin 2 and sliding cavity 11, which solves the problem that pin 2 is not adjustable in traditional applications. At the same time, the rubber seat 12 and the upper plug 10 work together to effectively prevent pin 2 from shaking or slipping out due to external force, thus improving the stability and safety of the product in practical applications.

[0037] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
