Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, and more specifically, to a novel power-on plug-in device for PCBA boards. Background Technology

[0002] PCBA, also known as Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and provides the connection for their circuitry. Because it is manufactured using electronic printing technology, it is called a "printed" circuit board. PCBA boards generally undergo packaging and testing before leaving the factory. Only those that pass the tests are released for use. During the coupling production process, the PCBA board needs to be powered on to ensure the optical chips on it function properly. However, current technology typically involves manually holding the PCBA board during insertion and removal. This can easily damage the gold wires and chips on the board, causing circuit interruptions or chip damage. Furthermore, the strong bond between the PCBA board and the socket means that holding the edge of the board during insertion and removal can easily cut the hand. The strong bond also requires wiggling the PCBA board from side to side to remove it, which can damage the gold fingers. Additionally, current devices do not effectively control the position of the PCBA board during insertion and removal, allowing it to potentially pop out of its mounting position and damage the gold fingers. For example, a power-on device disclosed in patent application number CN202321817894.4 abuts against one straight edge of a PCBA board. During insertion and removal, the PCBA board is prone to shaking and deformation, which can easily damage the gold fingers of the PCBA board. Summary of the Invention

[0003] One object of this invention is to solve at least the aforementioned problems and / or defects, and to provide at least the advantages described below.

[0004] To achieve these objectives and other advantages of the present invention, a novel power-on plug-in device for a PCBA board is provided, comprising: a power-on board, a socket port disposed at one end of the power-on board and connected to the PCBA board, and a limiting component for fixing the PCBA board is slidably disposed at the other end of the power-on board, the limiting component comprising: a base slidably disposed on the power-on board, the base having an installation position adapted to the shape of the PCBA board;

[0005] The base has limiting members on both sides to fix the position of the PCBA board. The front end of the limiting member has an arc-shaped protrusion that matches the side groove of the PCBA board. The arc-shaped protrusion has L-shaped limiting parts on both sides to limit the vertical position of the PCBA board. The end of the mounting position away from the socket is provided with a stop.

[0006] Preferably, the limiting member includes: a limiting block passing through the side wall of the base, and a stop plate is provided on the end face of the limiting block away from the PCBA board;

[0007] The arc-shaped protrusion and the L-shaped limiting part are both located on the other end face of the limiting block.

[0008] Preferably, the front end face of the extension of the L-shaped limiting part is configured as a guide slope.

[0009] Preferably, a spring is provided between the stop plate and the base, and a protruding stop block is provided on the lower surface of the limiting block;

[0010] The base and the stop block have a sliding groove on their contact surface, and the stop plate and the spring have an installation groove for the spring to be installed on their contact surface.

[0011] Preferably, the power supply plate is provided with a guide boss, and the base is provided with a guide groove that cooperates with the guide boss.

[0012] This utility model has at least the following beneficial effects: By tightly fitting the arc-shaped protrusion at the front end of the limiting part with the groove on the side of the PCBA board, the position of the PCBA board can be limited. At the same time, the L-shaped limiting part limits the vertical position of the PCBA board, preventing the PCBA board from jumping during insertion and removal, which could damage the gold fingers.

[0020] like Figure 1The present invention discloses a novel power-on plug-in device for a PCBA board, comprising: a power-on board 1, a socket 2 disposed at one end of the power-on board 1 and connected to a PCBA board 3, and a limiting component 4 for fixing and mounting the PCBA board 3 slidably disposed at the other end of the power-on board 1, the limiting component 4 comprising: a base 41 slidably disposed on the power-on board 1, the base 41 having an mounting position 43 adapted to the shape of the PCBA board 3;

[0021] The base 41 has two side walls with limiting members 42 for fixing the position of the PCBA board 3. The front end of the limiting member 42 has an arc-shaped protrusion 423 that matches the side groove of the PCBA board 3. The arc-shaped protrusion 423 has L-shaped limiting parts 424 on both sides to limit the vertical position of the PCBA board 3. The mounting position 43 has a stop part 431 at the end away from the socket port 2.

[0022] Working principle:

[0023] The mounting position 43 on the base 41 is adapted to the shape of the PCBA board 3, allowing the PCBA board 3 to be placed stably within the mounting position 43. A stop 431 at one end of the mounting position 43 restricts movement of the PCBA board 3 during the connection process. Next, the limiting member 42 is moved so that the arc-shaped protrusion 423 on the front end of the limiting member 42 contacts the groove on the side of the PCBA board 3, achieving a tight fit and precise horizontal positioning of the PCBA board 3. Simultaneously, the L-shaped limiting parts 424 on both sides of the arc-shaped protrusion 423 hold the PCBA board 3 in place, limiting its vertical position and ensuring that the PCBA board 3 does not shift vertically. Then, the base 41 is pushed to move along the direction of the socket 2 on the power supply board 1.

[0024] As PCBA board 3 continues to move towards socket 2, the gold fingers of PCBA board 3 are inserted into socket 2. At this point, PCBA board 3 and socket 2 are accurately connected, completing the installation and power-on process of the power-on / plug-out device.

[0025] When it is necessary to disassemble PCBA board 3, slide the base 41 in the opposite direction to separate PCBA board 3 from socket 2, and then remove PCBA board 3 from the mounting position 43 of base 41 to complete the disassembly operation. This utility model can realize the position limitation of PCBA board 3 by the tight cooperation between the arc-shaped protrusion 423 at the front end of the limiting member 42 and the side groove of PCBA board 3. At the same time, the L-shaped limiting part limits the vertical position of PCBA board 3 to prevent PCBA board 3 from jumping during insertion and removal, which would cause damage to the gold fingers.

[0026] In the above technical solution, the limiting member 42 includes: a limiting block 421 passing through the side wall of the base 41, and a stop plate 422 is provided on the side end face of the limiting block 421 away from the PCBA board 3; wherein, the arc-shaped protrusion 423 and the L-shaped limiting part 424 are both provided on the other side end face of the limiting block 421. With this technical solution, the limiting block 421 is installed on the side wall of the base 41. Before installing the PCBA board 3, the position of the limiting block 421 is adjusted so that the arc-shaped protrusion 423 and the L-shaped limiting part 424 on the limiting block 421 will not slide out of the through hole 46 on the side wall of the base 41, thus not affecting the installation of the PCBA board 3. After the PCBA board 3 is installed, the stop plates 422 on both sides are manually pinched to move the limiting block 421 toward the PCBA board 3. The arc-shaped protrusion 423 and the L-shaped limiting part 424 limit and fix the PCBA board 3. When it is necessary to disassemble the PCBA board 3, the limiting block 421 can be moved by pulling the stop plate 422, which can easily and quickly release the limiting and fixing of the PCBA board 3.

[0027] In the above technical solution, the front end face of the extended end of the L-shaped limiting part 424 is configured as a guide slope. This slope design avoids direct pressure from the L-shaped limiting part 424 on the edge of the PCBA board 3, reducing damage to the PCBA board 3 caused by rigid collisions.

[0028] In the above technical solution, a spring 44 is provided between the stop plate 422 and the base 41, and a protruding stop block 425 is provided on the lower surface of the limiting block 421.

[0029] In this design, a sliding groove 45 is provided on the contact surface between the base 41 and the stop block 425, and an installation groove 4221 for installing the spring 44 is provided on the contact surface between the stop plate 422 and the spring 44. An installation hole 48 for the spring 44 to extend into is provided on the side wall. With this technical solution, the spring 44 is installed between the stop plate 422 and the base 41. The stop plate 422 is provided with an installation groove 4221 for the spring 44 to be embedded, ensuring that the spring 44 is installed firmly and in a precise position. The sliding groove 45 on the contact surface between the base 41 and the stop block 425 provides a guiding path for the sliding of the stop block 425. When the PCBA board 3 is not installed, the spring 44 is in an unstressed state, and the limiting block 421 is located in the through hole 46 on the side wall of the base 41. When the PCBA board 3 is installed, the stop plates 422 on both sides are pinched, causing the spring 44 to deform under force. The limiting block 421 extends out from the through hole 46, and the arc-shaped protrusion 423 extends into the side groove of the PCBA board 3. At the same time, the L-shaped limiting part 424 is located above the PCBA board 3, limiting its position. After the power-on test is completed, the stop plate 422 is released. Under the action of the spring 44, the stop plate 422 is pushed, which in turn drives the stop block 425 to slide in the opposite direction in the slide groove 45, so that the limiting block 421 returns to the initial position or a new equilibrium position, completing one working cycle. The slide groove 45 is not connected to the side wall of the base 41. With the cooperation of the stop block 425, it limits the movement position of the limiting block 421.

[0030] In the above technical solution, the power supply board 1 is provided with a guide boss 11, and the base 41 is provided with a guide groove 5 that cooperates with the guide boss 11. Using this technical solution, the base 41 can be quickly slid through the cooperation of the guide groove 5 and the guide boss 11, enabling rapid insertion and removal of the PCBA board 3 from the socket port 2.

[0031] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
