Description

Technical Field

[0001] This utility model relates to the field of board-to-board connector technology, specifically a multi-layer stacked board-to-board connector. Background Technology

[0002] As electronic devices continue to evolve towards thinner, lighter, and more multifunctional designs, board-to-board connectors, as key components for achieving electrical connections between circuit boards, are of paramount importance in terms of performance and structural design. Traditional single-layer board-to-board connectors can no longer meet the ever-increasing demands. On the one hand, with the increasing integration of electronic devices, the number of lines that need to be connected on the circuit board has increased dramatically. For example, in high-end smartphones, when the motherboard is connected to the circuit boards of various functional modules, the limited number of pins of a single-layer connector cannot achieve stable connection of numerous signal lines, resulting in obstructed signal transmission and affecting the overall performance of the device.

[0003] On the other hand, in terms of spatial layout, traditional connectors occupy a large space, which becomes a major obstacle for electronic devices that pursue thinness and lightness. For example, wearable devices have extremely compact internal spaces, and traditional connectors cannot fit into their small internal spaces, limiting the miniaturization design of the products. In addition, in terms of high-speed signal transmission, single-layer connectors have weak anti-interference capabilities, and signals are easily affected by external electromagnetic interference during transmission, resulting in signal distortion, attenuation and other problems, which cannot meet the requirements of emerging technologies such as 5G communication and high-speed data transmission. To address this, we propose a multi-layer stacked board-to-board connector. Utility Model Content

Connecting and fixing bolt 3: The connecting and fixing bolt 3 is a standard part, consisting of a screw and a head. The screw has threads and is used to mate with the threaded holes 11 on the side and the threaded holes of the bottom connecting boss 14 for tightening. The head is generally hexagonal, which is convenient to operate with tools such as wrenches to achieve a tight connection between the top cover plate 2 and the external support frame 1. Bottom connecting boss 14: Bottom connecting boss 14 is a columnar structure at the bottom of the top cover plate 2, which is evenly distributed. Threaded holes are machined on its side, which are concentrically corresponding to the threaded holes 11 on the side of the top of the outer support frame 1. The material is the same as that of the top cover plate 2 to ensure the overall structural strength and help to fix the top cover. Side threaded holes 11: The side threaded holes 11 are evenly distributed on the top of the outer support frame 1 and match the threaded holes of the bottom connecting boss 14. Its pitch and hole diameter are precise, ensuring that the connecting fixing bolts 3 can be screwed in smoothly, so that the top cover plate 2 is installed firmly and the overall structure of the connector is compact. Internal guide support sleeve 10: The internal guide support sleeve 10 is a hollow cylinder and is located between the bottom plates 6 of the adjacent board-to-board connector. It is made of plastic or metal, with a smooth inner wall. It can slide on the internal guide rod 12 and its two ends are connected to different bottom plates respectively.

They are generally made of metal, with a smooth surface and high diameter accuracy. The board-to-board connector base plate 6 slides on the rod to achieve precise guidance and positioning during the installation process. Bottom buffer support plate 5: The bottom buffer support plate 5 is flat and is usually made of elastic materials such as rubber and silicone. It covers the bottom surface of the inner side of the outer support frame 1 and is fixed to the bottom plate 6 of the board-to-board connector. Its elasticity can buffer the vibration and impact from the bottom and protect the internal structure of the connector. Top sliding fixing plate 8: The top sliding fixing plate 8 is a rectangular flat plate, mostly made of metal or high-strength plastic. Its bottom surface is connected to the bottom plate 6 of the board-to-board connector, and its four sides can slide inside the outer support frame 1. By cooperating with the top buffer spring 9, it can buffer external forces in the top direction and protect the connector. Top buffer spring 9: The top buffer spring 9 is a helical metal spring, which is evenly distributed between the top cover plate 2 and the top sliding fixed plate 8. The spring coefficient is carefully designed to effectively buffer the vibration and impact on the top and prevent the internal connection of the connector from becoming loose or damaged. Side anti-interference baffle 4: The side anti-interference baffle 4 is mostly made of metal, such as copper and aluminum, which has good conductivity and electromagnetic shielding performance. It is in the form of a sheet and is symmetrically fixed on the inner side of the outer support frame 1. Its function is to block external electromagnetic interference, ensure stable signal transmission of board-to-board connectors, and reduce signal distortion. Working Principle: When this multi-layer stacked board-to-board connector is in operation, a stable mounting structure is first constructed through the external support frame 1 and the internal guide mounting components. The external support frame 1 provides basic support for the entire connector. The internal guide rod 12 and the internal guide support sleeve 10 cooperate to ensure that the board-to-board connector base plate 6 can be accurately and quickly installed in place, achieving precise positioning. In terms of electrical connection, the side connection pins 7 and side connectors 13 on the board-to-board connector base plate 6 play a crucial role. When different circuit boards need to be connected, the side connection pins 7 are inserted into the corresponding slots, and the side connectors 13 are used to connect to other interface components, realizing the electrical connection between multiple circuit boards. Due to the multi-layer stacked structure, the number of board-to-board connector base plates 6 is increased, thus allowing for the connection of more lines and meeting the needs of electronic devices for transmitting a large number of signals. For example, in high-end smartphones, it can ensure the connection between the motherboard and numerous functional module circuit boards. For stable signal transmission, the internal buffer and anti-interference components work together to ensure protection and stability. The bottom buffer support plate 5, the top buffer spring 9, and the top sliding fixing plate 8 together form a buffer system. When the connector is subjected to vibration or impact, the bottom buffer support plate 5 can reduce the impact force from the bottom, while the top buffer spring 9 buffers the external force from the top, protecting the internal structure of the connector and preventing the connection from becoming loose or damaged due to external forces. The side anti-interference baffle 4 is installed on the side of the board-to-board connector and can effectively block external electromagnetic interference. In scenarios such as 5G communication and high-speed data transmission, it ensures the stability of signal transmission and reduces signal distortion and attenuation. At the same time, the entire connector is encapsulated and fixed by the top cover fixing component. The connecting fixing bolts 3 tightly connect the top cover plate 2 to the external support frame 1 to ensure the stability of the internal structure of the connector and prevent problems such as loosening of components during use, ensuring that the connector can work stably for a long time.
