An LED holder

Abstract

This invention proposes an LED bracket, including a support plate and a height limiting plate. The support plate and the height limiting plate are integrally structured and mounted on top of a PCBA. The support plate has a strip-shaped structure, and multiple sets of guide holes are sequentially formed along its length on its upper surface. These guide holes are circular holes that extend along the Z-axis of the support plate. Each set of guide holes consists of two adjacent holes along the Y-axis, and the spacing between these two holes corresponds to the spacing between the two pins of the LED. Multiple height limiting plates are spaced apart on the lower surface of the support plate. A positioning post is fixed to the bottom of each height limiting plate, extending perpendicular to the support plate. This structure ensures that the LEDs maintain a consistent mounting height on the printed circuit board, are neatly arranged, and are stably positioned. It is particularly suitable for the fixed installation of multiple LEDs in a low-voltage battery management system, ensuring overall assembly accuracy and reliability.

Description

Technical Field

[0001] This utility model relates to the field of LED technology, and in particular to an LED bracket. Background Technology

[0002] As a highly efficient and energy-saving light source, LEDs have been widely used in lighting, display, and signal indication. During the packaging and assembly of LED devices, it is typically necessary to precisely insert the LED leads into the solder holes on the printed circuit board (PCBA) and maintain a stable height position to ensure consistent soldering quality and optical performance.

[0003] Existing LED soldering methods often rely solely on simple hole positions for lead guidance, which can easily lead to misaligned leads and poor solder joints due to inaccurate guidance or improper positioning. Furthermore, inconsistent lead exposure heights on the PCBA after soldering can affect the overall assembly's flatness and reliability, and even the LED's luminous effect. Some LED support structures use individual height-limiting posts on the PCBA to restrict the LED's installation height. While cylindrical height-limiting posts can ensure LED lead insertion depth and reduce lead exposure to some extent, their discrete support structure typically only affects individual LEDs, lacking overall lateral connection and constraint between multiple LEDs. Moreover, when there are many LEDs densely distributed, congestion between the height-limiting posts can cause LEDs to tilt and become misaligned, posing a risk of tipping over during soldering and resulting in a high solder joint defect rate.

[0004] Especially in low-voltage battery management systems (BMS), multiple LEDs are often required to display various functions such as power status, operating status, and fault indication. Due to the large number and dense distribution of LEDs, without proper fixing and height control design, it is easy to cause problems such as inconsistent soldering heights and uneven arrangement. This not only affects the overall assembly quality of the circuit board but may also lead to unstable signal display and reduce the reliability of the BMS. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an LED bracket suitable for fixing multiple LEDs in a low-voltage battery management system (BMS), so that the LED pins can be kept neatly arranged and the welding height is uniform during the insertion and soldering process, thereby improving the PCBA assembly quality and the reliability of the LED indicator function.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: an LED bracket, including a support plate and a height limiting plate, wherein the support plate and the height limiting plate are integrally structured and disposed above the PCBA. The support plate has a strip-shaped structure, and multiple sets of guide holes are sequentially opened on the upper surface of the support plate along the length direction. The guide holes are circular holes that are arranged through the support plate along the Z-axis direction. Each set of guide holes consists of two adjacent holes along the Y-axis, and the distance between the two holes corresponds to the distance between the two pins of the LED. Multiple height limiting plates are arranged at intervals on the lower surface of the support plate. A positioning post is fixed at the bottom of each height limiting plate, and the positioning post extends in a direction perpendicular to the support plate.

[0007] Furthermore, the outer diameter of the positioning post matches the positioning hole on the PCBA.

[0008] Furthermore, the height of the height limiting plate is consistent with the height above the LED pins after they are soldered onto the PCBA.

[0009] Furthermore, each set of guide holes corresponds to a solder hole on the PCBA.

[0010] Furthermore, there are three height restriction plates.

[0011] The beneficial effects of this utility model are:

[0012] (1) This utility model can improve the guiding accuracy of LED pins. Through reasonable guiding design, it can effectively prevent LED pins from being skewed or offset during insertion, and ensure that the pins can be smoothly inserted into the soldering holes of PCBA, thereby reducing defects such as poor soldering and off-center soldering.

[0013] (2) This utility model can ensure the consistency of LED welding height. By adding a height limit design to the bracket structure, the exposed height of the LED remains uniform after the PCBA welding is completed, ensuring the overall flatness of the circuit board and the consistency of subsequent assembly.

[0014] (3) This utility model can improve the neatness of multiple LED arrangement. In view of the characteristics of a large number of LEDs and dense distribution in the low-voltage battery management system, the bracket can make each LED position neatly arranged, avoiding unevenness caused by installation error, thereby improving the appearance and assembly quality of the overall circuit board.

[0015] (4) This utility model can enhance the reliability of BMS signal indication. By improving the LED fixing method and welding consistency, it can effectively reduce the display instability caused by height differences or misalignment, so that power status, working status and fault indication signals can be output clearly and reliably, thereby improving the system's reliability.

[0020] The present invention will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] like Figure 1 As shown, this utility model provides an LED bracket, which includes a support plate 1, a height limiting plate 2, and a positioning column 21.

[0022] like Figure 1 and Figure 2 As shown, the support plate 1 has a strip-shaped structure, is disposed above the PCBA3, and is integrally formed with the height limiting plate 2. Multiple sets of guide holes 11 are sequentially formed on the upper surface of the support plate 1 along the X-axis. The guide holes 11 are circular holes and are arranged through the support plate 1 along the Z-axis. Each set of guide holes 11 consists of two adjacent holes along the Y-axis, and the spacing between these two holes corresponds to the spacing between the two pins of the LED4, ensuring that the two pins of the LED4 can sequentially pass through the guide holes 11 at the corresponding positions.

[0023] Three height-limiting plates 2 are arranged at intervals on the lower surface of the support plate 1. Each height-limiting plate 2 has a fixed positioning post 21 at its bottom. The height of each height-limiting plate 2 is the same as the height above the LED 4 pins after soldering them onto the PCBA3. The positioning post 21 extends perpendicular to the support plate 1. The outer diameter of the positioning post 21 matches the positioning hole 31 on the PCBA3 to achieve stable positioning of the LED bracket and the PCBA3.

[0024] like Figure 2The diagram shows the assembly schematic of the LED bracket of this utility model. During assembly, the LED bracket is first aligned with the PCBA3, with the positioning pins 21 inserted into the positioning holes 31 on the PCBA3, ensuring the support plate 1 is parallel to the PCBA3. At this time, the guide holes 11 on the support plate 1 correspond to the soldering holes 32 on the PCBA3. Subsequently, multiple LEDs 4 are installed one by one, their leads passing through the guide holes 11 on the support plate 1 and extending into the soldering holes 32 of the PCBA3.

[0025] like Figure 3 The diagram shows the assembled LED bracket of this utility model. After assembly, the LEDs 4 are evenly arranged above the support plate 1, with their leads extending through the guide holes 11 into the soldering holes 32 of the PCBA3. The height of the height limiting plate 2 is consistent with the required allowance for the LED leads after soldering on the PCBA3, thus ensuring a precise and uniform installation height of the LEDs 4 on the PCBA3. Finally, after the soldering process, the LEDs 4 and PCBA3 achieve a firm electrical connection.

[0026] In summary, the LED bracket of this utility model, through the cooperation of the support plate 1, the height limiting plate 2 and the positioning column 21, realizes the overall structural design of support, limiting and positioning, which can ensure the consistency and stability of the installation position of multiple LED lights 4 on PCBA 3.

All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
