This will not only affect the normal transmission of the signal, but also reduce the overall reliability of the connector, and thus affect the operating efficiency and safety of the entire system.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1 -Attached Figure 4 , the technical solutions in the embodiments of the present application are clearly and completely described. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0028] The inventor of the present application has found that the existing board-to-board connector is prone to unstable contact in high-frequency signal transmission and high-vibration environments. Therefore, the present application mainly adopts the following scheme: comprising a plug assembly 1 and a socket assembly 2 that are plugged into each other, the plug assembly 1 comprising a first insulating component 11 and a plurality of first terminal components 12 fixed in the first insulating component 11, the socket assembly 2 comprising a second insulating component 21 and a plurality of second terminal components 22 fixed in the second insulating component 21; when the plug assembly 1 and the socket assembly 2 are plugged into each other, the plurality of first terminal components 12 and the plurality of second terminal components 22 contact each other through at least two contact points, thereby achieving the effect of significantly improving the connection stability and reliability. The present application is further described in detail below.

[0029] Embodiment 1: The present application provides a board-to-board stable connector, referring to Figure 1 and Figure 2 , including a plug assembly 1 and a socket assembly 2 that are plugged into each other. The plug assembly 1 includes a first insulating component 11 and a plurality of first terminal components 12 fixed in the first insulating component 11, and the socket assembly 2 includes a second insulating component 21 and a plurality of second terminal components 22 fixed in the second insulating component 21. When the plug assembly 1 and the socket assembly 2 are plugged into each other, the plurality of first terminal components 12 and the plurality of second terminal components 22 contact each other through at least two contact points.

[0030] like Figure 2 , Figure 3 and Figure 4As shown, the first terminal component 12 of the embodiment of the present application includes a first board connection end 121 and a socket connection end 122, the first board connection end 121 is used to connect the circuit board, and the socket connection end 122 is used to connect the socket assembly 2. For example, the first board connection end 121 can be a welding pin or a buckle structure, and the socket connection end 122 can be a needle-shaped or sheet-shaped structure. The second terminal component 22 includes a second board connection end 221 and a plug connection end 222, the second board connection end 221 is used to connect the circuit board, and the plug connection end 222 is used to connect the plug assembly 1. Similarly, the second board connection end 221 can also be a welding pin or a buckle structure, and the plug connection end 222 can be a needle-shaped or sheet-shaped structure.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the socket connection end 122 of the first terminal component 12 of the embodiment of the present application includes a first bend 1221 and a first inclined portion 1222, and the plug connection end 222 of the second terminal component 22 includes a second bend 2221 and a second inclined portion 2222. The first bend 1221 and the second inclined portion 2222 contact to form a first contact point 31, and the second bend 2221 and the first inclined portion 1222 contact to form a second contact point 32. This dual contact point design can significantly improve the stability and reliability of the connection in high-frequency signal transmission and high-vibration environments. Specifically, the contact area between the first bend 1221 and the second inclined portion 2222 is large, which can effectively disperse the contact pressure and reduce local stress concentration; and the contact angle between the second bend 2221 and the first inclined portion 1222 is reasonably designed to ensure that a good contact state can be maintained even under slight vibrations.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, the thickness of the socket connection end 122 of the first terminal component 12 of the embodiment of the present application is greater than the thickness of the first board connection end 121, and the thickness of the plug connection end 222 of the second terminal component 22 is greater than the thickness of the second board connection end 221. This design allows the plug connection end 222 and the socket connection end 122 to have higher rigidity, so that they are not easily deformed during the plug-in and pull-out process, ensuring the contact stability after long-term use. In addition, the thickened plug connection end 222 can better withstand the plug-in and pull-out force and extend the service life. The thicker plug connection end 222 and the socket connection end 122 can better resist the elastic force caused by vibration and reduce the terminal separation phenomenon caused by vibration. The thinner first board connection end 121 and the second board connection end 221 can further disperse the elastic force, thereby improving the reliability of the connector and the stability of signal transmission.

[0033] like Figure 2As shown, the first insulating component 11 of the embodiment of the present application has a first receiving groove 111 extending therethrough, the socket connection end 122 of the first terminal component 12 is received in the first receiving groove 111, and the first board connection end 121 of the first terminal component 12 extends from the top of the first receiving groove 111. Such a design is not only convenient for assembly, but also can effectively prevent the first terminal component 12 from loosening during the plugging and unplugging process. The first insulating component 11 is provided with a receiving cavity 112 near the second insulating component 21, and the receiving cavity 112 is connected to the first receiving groove 111, and the receiving cavity 112 is used to receive the socket connection end 122 of the first terminal component 12 and the plug connection end 222 of the second terminal component 22. The presence of the receiving cavity 112 makes the plug assembly 1 and the socket assembly 2 more stable during plugging and unplugging, avoiding damage caused by collision.

[0034] like Figure 2 As shown, the second insulating component 21 of the embodiment of the present application has a second receiving groove 211 extending therethrough, the plug connection end 222 of the second terminal component 22 is received in the second receiving groove 211, and the second board connection end 221 of the second terminal component 22 extends from the bottom of the second receiving groove 211. This design makes the positioning of the second terminal component 22 more accurate and reduces assembly errors. The second insulating component 21 has a third receiving groove 212 at both ends, the width of the third receiving groove 212 is smaller than the width of the second receiving groove 211, and a part of the second board connection end 221 of the second terminal component 22 is fixed in the third receiving groove 212. In this way, the fixing strength of the second terminal component 22 can be further increased, so that it is not easy to fall off when subjected to external force.

[0035] like Figure 2 As shown, the second insulating component 21 of the embodiment of the present application is provided with an insertion cavity 213 near the first insulating component 11, and the insertion cavity 213 is used to insert the first insulating component 11. The design of the insertion cavity 213 makes the plug assembly 1 and the socket assembly 2 more smoothly when docking, and also increases the sealing of the plug-in connection, preventing dust and moisture from entering the interior and affecting the connection performance.

[0036] The implementation principle of this embodiment is: through the design of double contact points, the contact stability and reliability of the board-to-board connector in high-frequency signal transmission and high-vibration environments are significantly improved. The contact surface of the first bend 1221 and the second inclined portion 2222 is large, which can effectively disperse the contact pressure; the angle design of the second bend 2221 and the first inclined portion 1222 is reasonable, and can maintain good contact under slight vibrations. The thickened plug connection end 222 enhances rigidity, has strong deformation resistance, and has a longer service life. The internal structural design of the first insulating component 11 and the second insulating component 21 enables accurate positioning of each part, easy assembly, and has good dust and water resistance, which improves the reliability and durability of the connector as a whole.

[0037] Embodiment 2: The present embodiment is different from the above embodiment in that the socket connection end 122 of the first terminal component 12 further includes a reinforcing rib, which is located between the first bending portion 1221 and the first inclined portion 1222, so as to enhance the structural strength of the entire socket connection end 122. The plug connection end 222 of the second terminal component 22 further includes a guide protrusion, which is located between the second bending portion 2221 and the second inclined portion 2222, so as to facilitate rapid alignment of the plug assembly 1 and the socket assembly 2 during plugging.

[0038] In the specific implementation process, the reinforcing ribs can be protrusions of circular, square or other geometric shapes, and their height and width can be adjusted according to actual needs. The presence of the reinforcing ribs makes it difficult for the first terminal component 12 to bend and deform during the plugging and unplugging process, especially in the case of frequent plugging and unplugging, and it can still maintain a stable contact state. The guide protrusion can be conical, rectangular or other shapes suitable for guiding, and its length and diameter also need to be selected according to actual conditions. The function of the guide protrusion is to play a guiding role when the plug assembly 1 and the socket assembly 2 are plugged in, so that the plugging process is smoother and the possibility of misalignment is reduced.

[0039] The implementation principle of this embodiment is as follows: by adding reinforcing ribs and guide protrusions, the structural strength and plug-in accuracy of the board-to-board connector are further improved. The presence of the reinforcing ribs makes the first terminal component 12 more robust during the plug-in and pull-out process, reducing fatigue damage caused by repeated plug-in and pull-out. The design of the guide protrusion makes it easier to align the plug assembly 1 and the socket assembly 2 during plug-in, reducing the risk of misoperation and improving the user experience. Overall, these improvement measures not only improve the physical performance of the connector, but also greatly improve the user experience.

[0040] Embodiment 3: The difference between this embodiment and the above-mentioned embodiment is that the outer surfaces of the first insulating component 11 and the second insulating component 21 are both provided with anti-slip patterns to increase the grip and friction. The front end of the first insulating component 11 is provided with an indicator mark, which is used to show the correct plugging direction. The rear end of the second insulating component 21 is provided with a locking mechanism, which can automatically lock after the plug assembly 1 is fully inserted into the socket assembly 2 to prevent accidental disengagement.

[0041] In the specific implementation process, the anti-slip pattern can be uneven lines, grids or other texture patterns, the purpose of which is to increase the friction between the fingers and the insulating parts, so that users can plug and unplug the connector more easily. The indicator mark can be an arrow, text or other easily recognizable mark to help users correctly insert the plug assembly 1 into the socket assembly 2 to avoid damage caused by reverse plugging. The locking mechanism can be a button-type, knob-type or other form of locking device. Its working principle is that after the plug assembly 1 is fully inserted into the socket assembly 2, self-locking is achieved through mechanical action, and the plug assembly 1 can only be pulled out in the unlocked state.

[0042] The implementation principle of this embodiment is as follows: by providing anti-slip patterns, indicator marks and locking mechanisms on the outer surface, the operation convenience and safety of the board-to-board connector are further improved. The anti-slip patterns increase the grip, making it easier for users to plug and unplug. The indicator marks help users operate correctly and avoid incorrect plugging. The locking mechanism ensures that the connector will not be detached due to unexpected vibrations during use, thereby improving the stability of the connection. These improvements enable the connector to perform well in various complex environments and meet higher-level usage requirements.

[0043] Embodiment 4: The difference between this embodiment and the above embodiment is that the materials of the first insulating component 11 and the second insulating component 21 are high-performance engineering plastics, such as polycarbonate (PC), nylon (PA) or polyoxymethylene (POM). The materials of the first terminal component 12 and the second terminal component 22 are copper alloy or stainless steel to improve the conductivity and corrosion resistance. The inner and outer surfaces of the first insulating component 11 and the second insulating component 21 are coated with a protective coating, which has the functions of anti-static, anti-oxidation and wear resistance.

[0044] Specifically, high-performance engineering plastics have high mechanical strength, heat resistance and chemical resistance, and are suitable for a variety of harsh environments. For example, polycarbonate has excellent impact strength and transparency, and is suitable as a material for visible parts; nylon has excellent toughness and wear resistance, and is suitable for applications that require frequent plugging and unplugging; polyoxymethylene has extremely high hardness and low friction coefficient, and is suitable for making precision parts. Copper alloys have good electrical conductivity and processing properties, and are often used as electrical connectors; stainless steel has excellent corrosion resistance and high temperature stability, and is suitable for applications that require long-term exposure to humid or acidic and alkaline environments.

[0045] In the specific implementation process, the protective coating can be made of nanomaterials, silicone resins or fluorocarbon coatings, and its thickness is generally in the range of several microns to tens of microns. The main function of the protective coating is to prevent static electricity accumulation, delay oxidation reactions and reduce wear, thereby extending the service life of the connector. Specifically, the anti-static coating can effectively release static charges and prevent data loss or equipment failure caused by electrostatic discharge; the antioxidant coating can prevent oxygen and other harmful substances from reacting with the substrate and maintain the original properties of the material; the wear-resistant coating can resist friction loss during long-term use and maintain the good appearance and performance of the connector.

[0046] The implementation principle of this embodiment is: through the selection of materials and surface treatment, the performance and durability of the board-to-board connector are comprehensively improved. The combination of high-performance engineering plastics and copper alloy / stainless steel not only ensures the mechanical strength and conductivity of the connector, but also has good corrosion resistance and high temperature stability. The addition of protective coating further enhances the anti-static, anti-oxidation and wear resistance of the connector, so that it still performs well under various harsh working conditions. In short, the optimized design of these materials and technologies has significantly improved the overall quality and service life of the connector, meeting the higher requirements of modern electronic equipment for connectors.

[0047] Embodiment 5: The difference between this embodiment and the above-mentioned embodiment is that: the sides of the first insulating component 11 and the second insulating component 21 are provided with heat dissipation holes, and the layout and size of the heat dissipation holes are optimized to improve the heat dissipation efficiency. A temperature sensor is provided at the contact point of the first terminal component 12 and the second terminal component 22, and the temperature sensor can send real-time temperature data to the monitoring system in a wireless manner. A thermal pad is provided inside the first insulating component 11 and the second insulating component 21, and the thermal pad is used to quickly conduct heat to the housing to accelerate the heat dissipation process.

[0048] In the specific implementation process, the heat dissipation holes can be arranged in a linear, mesh or other arrangement, and their number and size need to be determined according to the actual heating situation. The optimized heat dissipation holes can not only effectively discharge the heat generated inside, but also introduce cold air from the outside to form natural convection and accelerate the cooling speed. The temperature sensor can be a thermistor, an infrared thermometer or a semiconductor temperature sensor, which are characterized by fast response speed and high measurement accuracy. The real-time monitoring function of the temperature sensor allows the user to understand the working status of the connector at any time, take cooling measures in time, and avoid safety accidents caused by overheating. The thermal pad can be made of graphene, aluminum foil or other high-efficiency thermal conductive materials, and its thickness and density can be adjusted according to actual needs. The presence of the thermal pad allows the heat to be quickly transferred from the contact point to the outer shell, and then dissipated back into the air through the heat dissipation holes, forming an efficient heat dissipation path.

[0049] The implementation principle of this embodiment is: by adding heat dissipation holes, temperature sensors and thermal pads, the heat dissipation capacity and safety performance of the board-to-board connector are greatly improved. The design of the heat dissipation holes makes full use of the principle of natural convection to improve the efficiency of heat exchange; the real-time monitoring function of the temperature sensor provides users with important operating parameters, which is convenient for early warning and prevention of potential risks; the effective heat transfer of the thermal pad ensures the rapid transfer of heat and reduces the temperature of the contact point. In summary, these improvement measures not only solve the problem of insufficient heat dissipation in traditional connectors, but also enhance the overall stability and safety of the system, and are particularly suitable for high-power, high-frequency electronic devices.

[0050] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
