Technical Field
[0001] This utility model relates to the field of high-density board-to-board connector technology, specifically a high-efficiency moisture-proof high-density board-to-board connector. Background Technology
[0002] High-density, moisture-resistant board-to-board connectors are indispensable components in modern electronic devices. Their high-density design, moisture resistance, and reliable electrical and mechanical properties enable them to maintain stable connections in complex environments. Through proper selection and design, these connectors can meet the high-performance requirements of fields such as communications, automotive electronics, industrial automation, and medical devices, ensuring the stable operation of electronic equipment.
[0003] Currently available high-efficiency moisture-proof high-density board-to-board connectors are difficult to remove due to their tight connection. If a person lacks patience and uses force to remove them, the connection between the socket and the high-density board body may break, causing the device to become unusable later.
[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a high-efficiency, moisture-proof, high-density board-to-board connector. Utility Model Content

The ejection assembly, used to facilitate plug removal, is installed on the upper and lower sides of the plug. The ejection assembly includes a pressure plate, a slider, a return spring, and a push rod. The bottom left side of the pressure plate is slidably connected to a slider, and the left end of the slider is vertically provided with a return spring. The push rod is inserted inside the return spring and is slidably connected to the left side of the plug.

[0011] Preferably, the top end of the fastening screw is threadedly connected to the bottom of the socket, and a sealing gasket is fixedly installed on the right side of the socket, and the overall shape of the sealing gasket is set in a "hui" character structure.
[0012] Compared with the prior art, the beneficial effects of the present utility model are: the high-efficiency moisture-proof high-density board-to-board connector can not only reduce the difficulty of disconnection, but also reduce the detachment at the connection between the socket and the high-density board main body, and improve the connection stability.
[0013] 1. Through the setting of the pushing component in the present utility model, by pressing the pressing plate, the pressing plate moves downward, and the inclined surface at the bottom of the pressing plate pushes the slider with the same inclined surface to continuously move to the left, and applies a thrust to the ejector rod arranged inside the return spring, so that the ejector rod converts the force to push the socket into the auxiliary force for the plug to move to the right, facilitating the user to remove the plug more labor-savingly, so as to achieve the purpose of reducing the difficulty of disconnection.

[0021] 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.
[0022] like Figures 1-3 As shown, a high-efficiency moisture-proof high-density board to board connector includes a high-density board body 1 and an ejection assembly 5. The top right side of the high-density board body 1 is electrically connected to a pin 2, and the end of the pin 2 is electrically connected to a socket 3. The right end of the socket 3 is connected to a plug 4. The ejection assembly 5, which is used to improve the removal of the plug 4, is installed on the upper and lower sides of the plug 4. The ejection assembly 5 includes a pressure plate 501, a slider 502, a return spring 503, and a push rod 504. The slider 502 is slidably connected to the bottom left side of the pressure plate 501, and the return spring 503 is vertically arranged at the left end of the slider 502. The push rod 504 is inserted inside the return spring 503, and the push rod 504 is slidably connected to the left side of the plug 4.
[0023] By adopting the above technical solution, pressing the pressure plate 501 causes it to move downwards, and the inclined surface at the bottom of the pressure plate 501 pushes the slider 502, which has the same inclined surface, to move continuously to the left. This applies a pushing force to the push rod 504 inside the reset spring 503, so that the push rod 504 converts the force pushing the socket 3 into an auxiliary force that moves the plug 4, making it easier for the user to remove the plug 4 with less effort and improving ease of use.
[0024] like Figures 1-4 As shown, the front and rear ends of the plug 4 are symmetrically provided with slots 6, and spring blocks 7 are engaged inside the slots 6.
[0025] By adopting the above technical solution, the spring block 7 can be quickly and easily connected with the slot 6.
[0026] Furthermore, a flip plate 8 is slidably connected to the outer wall of the spring block 7, and the left end of the flip plate 8 is rotatably connected to the socket 3.
[0027] By adopting the above technical solution, the flip plate 8 reduces the interference of the spring clip 7 on the plug 4 when it unfolds.
[0028] Furthermore, a top plate 9 is provided at the bottom right of the high-density board main body 1, and a soft rubber pad 10 is laid on the top left of the top plate 9.
[0029] By adopting the above technical solution, the soft rubber pad 10 increases the friction force in the contact area between the top plate 9 and the bottom of the high-density board main body 1.
[0030] Furthermore, threaded holes 11 are symmetrically opened at the front and back of the top right of the top plate 9, and fastening screws 12 are threadedly connected to the inner walls of the threaded holes 11.
[0031] By adopting the above technical solution, the fastening screws 12 control the clamping force of the top plate 9 and the socket 3 on the high-density board main body 1.
[0032] Furthermore, the top end of the fastening screw 12 is threadedly connected to the bottom of the socket 3, and a sealing pad 13 is fixedly installed on the right side of the socket 3, and the overall shape of the sealing pad 13 is set in a "return" shape structure.
[0033] By adopting the above technical solution, the sealing pad 13 reduces the entry of water vapor through the socket 3 and the plug 4, improving the waterproof performance.
[0034] Working principle: When using this high-efficiency moisture-proof high-density board board-to-board connector, first, when the fastening screw 12 passes through the threaded hole 11 and is threadedly connected to the socket 3, rotate the fastening screw 12, so that the fastening screw 12 continuously screws into the bottom of the socket 3. While the fastening screw 12 rotates, it pulls the top plate 9 upward, and makes the top plate 9 and the soft rubber pad 10 provided on its top continuously exert an extrusion force on the connection part of the high-density board main body 1, and makes the socket 3 tightly fixed at the right end of the high-density board main body 1. When the socket 3 and the plug 4 need to be separated, the pressing plate 501 can be pressed, so that the pressing plate 501 moves downward, and the inclined plane provided at the bottom of the pressing plate 501 pushes the slider 502 with the same inclined plane to continuously move to the left, and applies a thrust to the ejector rod 504 provided inside the return spring 503, so that the ejector rod 504 converts the force to push the socket 3 into an auxiliary force for the plug 4 to move to the right, facilitating the user to remove the plug 4 more labor-saving. This is the working principle of this high-efficiency moisture-proof high-density board board-to-board connector.
