Description
Technical Field
[0001] This application relates to the field of PCBA board technology, and more specifically, to a splicing PCBA board. Background Technology
[0002] PCBA board is short for Printed Circuit Board Assembly, which is a circuit board with soldered electronic components. It includes a PCB board, which is usually a green rigid board (there are also flexible boards). The board has copper foil etched to form conductors and electronic components, including resistors, capacitors, chips, diodes, transistors, etc.
[0003] PCBA boards fix scattered electronic components onto a unified board and achieve electrical connections between components through internal wires, replacing traditional manual wiring. The combination of different components gives PCBA boards specific functions and achieves different effects.
[0004] In existing integrated PCBA boards, when a fault occurs, the faulty area may only involve a low-cost component (such as a resistor or capacitor). However, since it cannot be replaced individually, the cost of purchasing the entire PCBA board must be borne. Especially when the board integrates high-value chips, the cost can increase several times or even dozens of times. At the same time, additional labor costs for overall disassembly, resoldering, and debugging are also required. In view of this, we propose a spliced PCBA board. Summary of the Invention

[0015] 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.
[0016] Reference Figures 1-5 This application discloses a splicing PCBA board, including an outer sleeve 1, a PCBA body 2, pins on all four sides of the end face of the PCBA body 2, a rubber pad 3, and a graphene heat dissipation coating 4. The inner side of the outer sleeve 1 is L-shaped with two sides respectively provided with recessed terminals 5 or protruding terminals 6. Both the recessed terminals 5 and the protruding terminals 6 are electrically connected to the pins. The outer sides of the outer sleeve 1 are provided with plugging and unplugging mechanisms, and the recessed terminals 5 and the protruding terminals 6 are electrically connected.
[0017] When multiple PCBA boards need to be spliced, the protruding terminal 6 on the outer sleeve 1 of one PCBA board is aligned with the concave terminal 5 on the outer sleeve 1 of another PCBA board. Through physical docking, the protruding terminal 6 is embedded into the concave terminal 5, completing the initial mechanical splicing. Since both the concave terminal 5 and the protruding terminal 6 are electrically connected to the pins of the PCBA body 2, and electrical conduction can be achieved between the concave terminal 5 and the protruding terminal 6, after the protruding terminal 6 is embedded into the concave terminal 5, the pins of the two PCBA boards form an electrical connection path through the concave terminal 5 and the protruding terminal 6, ensuring that electrical signals can be transmitted and interacted between multiple PCBA boards. At the same time, through physical docking, the insertion and removal mechanism connects the outer sleeves 1 of the two PCBA boards, achieving a stable fixation after the PCBA boards are spliced, preventing the spliced PCBA boards from loosening or separating due to external forces such as vibration and collision during use, thus improving structural stability.
[0018] Reference Figure 4 and Figure 5 The insertion and removal mechanism includes a slot 11, which is symmetrically opened on the outside of the outer sleeve 1. The slot 11 has symmetrically opened telescopic grooves 12 on the inside of the slot 11. A spring 13 is fixedly installed on the inside of the telescopic groove 12. A ball 14 is fixedly installed at the end of the spring 13. The ball 14 is slidably installed on the inside of the insertion groove 16. The insertion groove 16 is opened on the outside of the insertion block 15. The insertion block 15 is slidably installed on the inside of the slot 11. The insertion block 15 is fixedly installed on the outside of the outer sleeve 1. The outer side of the insertion block 15 has symmetrically opened inclined surfaces.
[0019] When splicing two PCBA boards, insert block 15 is aligned with slot 11 and inserted. Since insert block 15 has a beveled outer surface, initially, the beveled surface contacts ball bearing 14 and exerts a squeezing force on the ball bearing 14, causing it to move into the telescopic groove 12. Simultaneously, spring 13 is compressed. As insert block 15 continues to be inserted, when the insertion groove 16 on insert block 15 moves to the position corresponding to ball bearing 14, spring 13 returns to its original deformation, pushing ball bearing 14 into the insertion groove 16, thus limiting the insertion block 15. Once the insertion operation is complete, when it is necessary to separate the PCBA board, a pulling force is applied in the opposite direction. The pulling force acts on the insert block 15, causing the inner wall of the embedding groove 16 to squeeze the ball 14, pressing the ball 14 into the telescopic groove 12 again. At this time, the insert block 15 can be smoothly pulled out from the slot 11, realizing the separation of the two PCBA boards. Through the cooperation of the spring 13 and the ball 14, the spliced PCBA board is prevented from loosening or separating due to external forces such as vibration and collision during use, thus improving the structural stability.
[0020] Reference Figure 2 and Figure 3 The rubber pad 3 and the graphene heat dissipation coating 4 form a group to wrap and protect the PCBA body 2. The outer sleeve 1 has a heat dissipation groove 17 on the outside, which is located above the rubber pad 3.
[0021] The rubber pad 3 has good elasticity and cushioning performance. Wrapped around the outside of the PCBA body 2, it can effectively absorb external impact and vibration energy, preventing damage to the PCBA body 2 and components on the board due to external collisions and vibrations. At the same time, the PCBA body 2 generates heat during operation. The graphene heat dissipation coating 4 has extremely high thermal conductivity. Wrapped around the outside of the PCBA body 2, it can quickly conduct the heat generated by the PCBA body 2 to the outside. Together with the heat dissipation slot 17, it can achieve efficient heat dissipation, preventing the PCBA body 2 from degrading in performance, shortening its lifespan, or even burning out due to excessive temperature.
[0022] In summary, the working principle and usage process of this utility model are as follows: When multiple PCBA boards need to be spliced, the protruding terminal 6 on the outer sleeve 1 of one PCBA board is aligned with the concave terminal 5 on the outer sleeve 1 of another PCBA board. Through physical mating, the protruding terminal 6 is embedded into the concave terminal 5, completing the initial mechanical splicing. Since both the concave terminal 5 and the protruding terminal 6 are electrically connected to the pins of the PCBA body 2, and electrical conductivity can be achieved between them, when the protruding terminal 6 is embedded into the concave terminal 5, the pins of the two PCBA boards form an electrical connection path through the concave terminal 5 and the protruding terminal 6, ensuring that electrical signals can be transmitted between the multiple PCBA boards. During the physical docking process, the insertion and removal mechanism connects the two PCBA boards via the external sleeve 1, achieving a stable fixation of the PCBA boards after splicing. This prevents the spliced PCBA boards from loosening or separating due to external forces such as vibration and collision during use, thus improving structural stability. When splicing two PCBA boards, the insertion block 15 is aligned with the slot 11 and inserted. Since the outer side of the insertion block 15 has a bevel, initially, the bevel contacts the ball bearing 14 and exerts a squeezing force on the ball bearing 14, causing the ball bearing 14 to move into the telescopic groove 12. At the same time, the spring 13 is compressed. As the insertion block 15 continues to be inserted, when the insertion block 15... When the insert groove 16 moves to the position corresponding to the ball 14, the spring 13 returns to its original deformation, pushing the ball 14 into the inner side of the insert groove 16, thus limiting and fixing the insert block 15, completing the insertion operation. When it is necessary to separate the PCBA board, a pulling force is applied in the opposite direction. The pulling force acts on the insert block 15, causing the inner wall of the insert groove 16 to squeeze the ball 14, pressing the ball 14 into the telescopic groove 12 again. At this time, the insert block 15 can be smoothly pulled out from the slot 11, realizing the separation of the two PCBA boards. Through the cooperation of the spring 13 and the ball 14, the spliced PCBA board is prevented from being damaged by external forces such as vibration and collision during use. Loosening or separating enhances structural stability. The rubber pad 3 has good elasticity and cushioning performance. Wrapped around the outside of the PCBA body 2, it can effectively absorb external impact and vibration energy, preventing damage to the PCBA body 2 and components on the board due to external collisions and vibrations. At the same time, the PCBA body 2 generates heat during operation. The graphene heat dissipation coating 4 has extremely high thermal conductivity. Wrapped around the outside of the PCBA body 2, it can quickly conduct the heat generated by the PCBA body 2 to the outside. Together with the heat dissipation groove 17, it can achieve efficient heat dissipation, preventing the PCBA body 2 from degrading in performance, shortening its lifespan, or even burning out due to excessive temperature.
