Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to a circuit board and an electronic equipment. Background Art

[0002] In the related art, patch nuts are welded on the circuit board to fix the circuit board. However, since the patch nuts are only welded to the surface of the circuit board, the connection force between the circuit board and the patch nuts is low, and the connector is easily detached, resulting in low reliability of circuit board fixation. Summary of the invention

[0003] The present application aims to provide a circuit board and an electronic device, which can solve one of the technical problems in the related art that the connection strength between the connecting parts on the circuit board and the circuit board substrate is low and easy to fall off.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In a first aspect, the present application provides a circuit board, comprising:

[0006] substrate;

[0007] A cover plate, arranged on the base plate;

[0008] The connecting member includes a connecting portion, the connecting member is fixed to the cover plate, and the connecting portion of the connecting member is away from the base plate and exposed to the outside of the cover plate.

[0009] In a second aspect, the present application provides an electronic device, including:

[0010] A circuit board as provided in the first aspect.

[0011] In an embodiment of the present application, the circuit board includes a substrate, a cover plate and a connector, wherein the cover plate is disposed on the substrate and connected to the substrate, the cover plate directly fixes or assists in fixing the connector, and the connecting portion of the connector is exposed outside the cover plate, thereby facilitating the connection between the connector and the external structural member.

[0012] Among them, the connection between the substrate and the connector utilizes a cover plate to increase the connecting force of the connector. Since the material of the substrate and the volume of the connector determine that the connection strength between the substrate and the connector is relatively low, while the cover plate is not affected by the material, therefore, whether the cover plate is connected and fixed to the connector alone so that the substrate and the connector are indirectly connected, or the cover plate and the substrate are connected and fixed to the connector together, the connection strength between the substrate and the cover plate as a whole and the connector can be increased, thereby improving the reliability of fixing the circuit board, and there is no need to open holes in the circuit board, which facilitates the wiring of the circuit board.

[0031] Combine the following Figures 1 to 10 A circuit board 100 and an electronic device according to an embodiment of the present application are described.

[0032] like Figures 1 to 7 As shown, a circuit board 100 according to an embodiment of the present application includes: a substrate 110; a cover plate 120, which is disposed on the substrate 110; and a connector 130, wherein the connector 130 includes a connecting portion 132, the connector 130 is fixed to the cover plate 120, and the connecting portion 132 of the connector 130 is away from the substrate 110 and exposed to the outside of the cover plate 120. Specifically, the connector 130 is described below by taking a patch nut as an example, and of course the connector 130 may also be a button, a dial wheel, a lever or other components.

[0033] In the embodiment of the present application, the circuit board 100 includes a substrate 110, a cover plate 120 and a connector 130, wherein the cover plate 120 is covered on the substrate 110 and connected to the substrate 110, the cover plate 120 directly fixes or assists in fixing the connector 130, and the connecting portion 132 of the connector 130 is exposed outside the cover plate 120, thereby facilitating the connection between the connector 130 and the external structural member. Direct fixing can be understood as the fixing of the connector 130 and the cover plate 120 by welding, bonding, clamping, plugging or other components, and assisting in fixing can be understood as the fixing of the cover plate 120 directly to the substrate 110, and the connecting force between the cover plate 120 and the substrate 110 and the entire cover plate 120 is improved through the direct or indirect connection between the cover plate 120 and the connector 130, thereby playing the role of assisting in fixing, and of course, the connector 130 can be directly fixed to both the cover plate 120 and the substrate 110.

[0034] Among them, the connection between the substrate 110 and the connector 130 uses the cover plate 120 to increase the connecting force of the connector 130. Since the material of the substrate 110 and the volume of the connector 130 determine that the connection strength between the substrate 110 and the connector 130 is relatively low, while the cover plate 120 is not affected by the material, therefore, whether the cover plate 120 is connected to the connector 130 alone, so that the substrate 110 and the connector 130 are indirectly connected, or the cover plate 120 and the substrate 110 are connected to the connector 130 together, the connection strength between the substrate 110 and the cover plate 120 as a whole and the connector 130 can be increased, that is, the connection in the related art in which the connector is subjected to force alone is improved to the connection 130 and the cover plate 120 being subjected to force together, thereby improving the reliability of fixing the circuit board 100, and there is no need to open holes on the circuit board 100, which facilitates the wiring of the circuit board 100.

[0035] Specifically, the cover plate 120 may be other functional structures that are additionally used on the connector 130 to increase the reliability of the connector 130 , or the cover plate 120 is only used to increase the reliability of the connector 130 .

[0036] The connection between the cover plate 120 and the base plate 110 may be welding or bonding, etc. In addition, the cover plate may be made of metal.

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, as a possible implementation, the peripheral side of the connecting member 130 includes a limiting structure, and the peripheral side of the cover plate 120 and the connecting member 130 are adapted. Specifically, the peripheral side of the connecting member 130 has a limiting structure, and the peripheral side of the cover plate 120 and the connecting member 130 fit together, thereby limiting the movement of the connecting member 130 in one direction or two directions, thereby further reducing the possibility of the connecting member 130 falling off.

[0038] Among them, the cover plate 120 can form a groove, which is matched with the peripheral side of the connector 130, and the peripheral side of the connector 130 is embedded in the groove to achieve the restriction of the connector 130. Or the cover plate 120 can form a socket, the edge of the socket is matched with the peripheral side of the connector 130, and the peripheral side of the connector 130 is embedded in the socket to achieve the restriction of the connector 130. In addition, the peripheral side of the connector 130 can form other non-circular shapes, such as: ellipse, triangle, quadrilateral, pentagon and other polygons, a combination of arcs and straight lines or other special-shaped structures. Furthermore, the peripheral side walls of other non-circular shapes on the connector 130 can play a role of limiting, reducing the risk of the connector 130 rotating and moving along the substrate 110.

[0039] Specifically, the example of the connection member 130 being able to move in the X, Y and Z directions relative to the substrate 110 is used for explanation. The X, Y and Z directions form a coordinate system, the Z direction is a direction perpendicular to the substrate 110, and the X and Y directions are directions parallel to the substrate 110. Thus, the upper limit structure of the connection member 130 and the cover plate 120 cooperate to limit the movement of the connection member 130 in at least one of the X and Y directions.

[0040] When the cover plate 120 is provided with a through hole 124 and the connector 130 is inserted through the through hole 124, the peripheral side of the connector 130 is limited by the cover plate 120, and the movement of the connector 130 in the X direction and the Y direction can be limited. Based on the cooperation between the limiting structure and the cover plate 120, the possibility of the connector 130 rotating and the possibility of the connector 130 being separated can be reduced.

[0041] like Figures 5 to 10 As shown, as a possible implementation, the connector 130 also includes: a head 134 connected to the substrate 110, the connecting portion 132 is located on the side of the head 134 away from the substrate 110, the cover 120 includes a through hole 124, the connecting portion 132 is passed through the through hole 124, and the cover 120 is pressed onto the head 134. Specifically, the connector 130 includes a head 134 and a connecting portion 132, the head 134 is arranged on one side of the connecting portion 132, the head 134 faces the substrate 110 and is connected to the substrate, and the head 134 protrudes from the connecting portion 132 from the peripheral side of the connecting portion 132, and the connecting portion 132 can pass through the cover plate 120 through the through hole 124 arranged on the cover plate 120. Since the head 134 protrudes from the peripheral side of the connecting portion 132, the head 134 is pressed and covered by the cover plate 120, and the cover plate 120 and the substrate 110 sandwich the head 134 in the middle, thereby reducing the risk of the connector 130 moving in a direction perpendicular to the substrate 110, increasing the connection strength between the substrate 110 and the cover plate 120 as a whole and the connector 130, and reducing the risk of the connector 130 falling off.

[0042] Among them, the peripheral side of at least one of the connecting part 132 and the head 134 has a limiting structure, and the through hole 124 and the limiting structure are adapted to each other, so that the connecting member 130 can be restricted in multiple directions, so that the connecting member 130 can maintain a posture as much as possible, reducing the risk of the connecting member 130 falling off.

[0043] Specifically, since the connector 130 passes through the through hole 124, the cover 120 can fully restrict the movement of the connector 130 along the X and Y directions. Moreover, since the cover 120 is also pressed on the head 134, the movement of the connector 130 in the Z direction can also be restricted.

[0044] like Figure 5 , Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, as a possible implementation, the cover plate 120 further includes: a limiting groove 122, which is located on the side of the cover plate 120 facing the substrate 110, the head 134 is embedded in the limiting groove 122, and the portion of the cover plate 120 located on the periphery of the limiting groove 122 is connected to the substrate 110. Specifically, the limiting groove 122 is provided on the cover plate 120, and the opening of the limiting groove 122 faces the substrate 110, so that the head 134 can be embedded in the limiting groove 122, wherein the through hole 124 is provided at the bottom of the limiting groove 122, the connecting portion 132 can be penetrated through the through hole 124 opened on the bottom of the limiting groove 122, and the portion of the cover plate 120 located on the periphery of the opening of the limiting groove 122 is connected to the substrate 110, so that the head 134 of the connecting member 130 is completely restricted by the substrate 110 and the cover plate 120, further increasing the restricting capacity of the connecting member 130 and further reducing the risk of the connecting member 130 falling off.

[0045] like Figures 5 to 7 As shown, as a possible implementation, the limiting structure is matched with the limiting groove 122. Specifically, the peripheral side of the head 134 has a limiting structure, and the peripheral side of the limiting groove 122 is matched with the limiting structure, so that the connecting member 130 can be restricted in multiple directions, so that the connecting member 130 can maintain a posture as much as possible, reducing the risk of the connecting member 130 falling off.

[0046] Specifically, the circumference of the head 134 is a non-circular shape, and after the head 134 is embedded in the limiting groove 122 , the connecting member 130 cannot rotate or move in the limiting groove 122 , thereby improving the limiting effect on the connecting member 130 .

[0047] Specifically, the limiting groove 122 can fully limit the movement of the connecting member 130 along the X direction and the Y direction, and because the bottom plate of the limiting groove 122 is also pressed on the head 134, the movement of the connecting member 130 in the Z direction can also be limited.

[0048] like Figure 6 and Figure 8 As shown, as a possible implementation, the connection portion 132 includes a screw hole 136, and the cover plate 120 is pressed on the peripheral side of the screw hole 136. Specifically, the connection portion 132 is provided with a screw hole 136, and the cover plate 120 is pressed on the peripheral side of the screw hole 136, so that the entire connection member 130 is pressed and covered by the cover plate 120, and the cover plate 120 and the substrate 110 sandwich the connection member 130 in the middle, thereby reducing the risk of the connection member 130 moving in a direction perpendicular to the substrate 110, increasing the connection strength between the substrate 110 and the cover plate 120 as a whole, and the connection member 130, and reducing the risk of the connection member 130 falling off.

[0049] like Figures 4 to 7 As shown, as a possible implementation, the connector 130 is fixedly connected to at least one of the cover plate 120 and the base plate 110. Specifically, the connector 130 can be fixedly connected to the cover plate 120, or fixedly connected to the base plate 110, or fixedly connected to both the cover plate 120 and the base plate 110.

[0050] For example, the side of the connector 130 facing the substrate 110 is connected to the cover plate 120 through the second connector 144; the side of the connector 130 facing the substrate 110 is connected to the substrate 110 through the first connector 142; the head 134 of the connector 130 is connected to the substrate 110 through the first connector 142, and the connecting portion 132 of the connector 130 is connected to the cover plate 120 through the second connector 144; the side of the connector 130 facing the substrate 110 is connected to the substrate 110 through The first connecting material 142 is connected, the side of the head 134 of the connecting piece 130 facing away from the cover plate 120 is connected to the cover plate 120 through the second connecting material 144; the side of the head 134 of the connecting piece 130 facing toward the substrate 110 is connected to the substrate 110 through the first connecting material 142, the side of the head 134 of the connecting piece 130 facing away from the cover plate 120 is connected to the cover plate 120 through the second connecting material 144, and the connecting portion 132 of the connecting piece 130 is connected to the cover plate 120 through the second connecting material 144.

[0051] The first connecting material 142 and / or the second connecting material 144 may be a solder or an adhesive.

[0052] like Figure 6 and Fig.10As shown, as a possible implementation, the cover plate 120 includes a multi-layer structure, the multi-layer structure is distributed from close to the substrate 110 to far away from the substrate 110, and the connecting member 130 is fixed to the multi-layer structure.

[0053] Specifically, the edge of the cover plate 120 is bent to form a multi-layer structure, and the layer of the multi-layer interface close to the substrate 110 is the first section 1282, and the side away from the substrate 110 is the second section 1284. The first section 1282 and the second section 1284 are connected by the third section 1286, wherein the area of ​​the first section 1282 is smaller than the area of ​​the second section 1284, and the third section 1286 determines the distance between the first section 1282 and the second section 1284.

[0054] Furthermore, a limiting groove 122 and a through hole 124 are formed on the side of the first section 1282 facing the substrate 110, and the head 134 of the connector 130 is disposed in the limiting groove 122, and the connecting portion 132 passes through the through hole 124 and abuts against the second section 1284. The second section 1284 is provided with an avoidance hole 126, so that the screw 230 can pass through the avoidance hole 126 on the second section 1284 and connect with the connector 130. Thus, a double limit is formed on the connector 130, and the reliability of the connector 130 is further improved.

[0055] Specifically, the limiting groove 122 can fully limit the movement of the connecting member 130 along the X direction and the Y direction, and because the bottom wall of the limiting groove 122 is also pressed on the head 134, the second section 1284 of the cover 120 is also pressed on the connecting portion 132, thereby enhancing the limiting effect on the movement of the connecting member 130 in the Z direction.

[0056] like Figure 1 and Figure 2 As shown, as a possible implementation, the circuit board 100 further includes: a shielding cover, which is disposed on the substrate 110, and the cover plate 120 and the shielding cover are an integrated structure; and / or a reinforcement plate, which is disposed on the substrate 110, and the cover plate 120 and the reinforcement plate are an integrated structure.

[0057] Specifically, the circuit board 100 includes a shielding cover, which is usually made of metal and is used to prevent the circuit board 100 from being interfered by external signals. The shielding cover and the cover plate 120 are set as an integrated structure, which can improve the reliability of the connector 130 on the basis of the original structure of the circuit board 100. In addition, there is usually a large connection area between the shielding cover and the substrate 110, which can increase the stability of the cover plate 120. The cover plate 120 can be a part extending from the shielding cover.

[0058] The circuit board 100 includes a reinforcing plate, which is usually made of metal and is used to improve the strength of the circuit board 100. The reinforcing plate and the cover plate 120 are then set as an integrated structure, which can improve the reliability of the connector 130 on the basis of the original structure of the circuit board 100. In addition, there is usually a large connection area between the reinforcing plate and the base plate 110, which can increase the stability of the cover plate 120. The cover plate 120 can be a part extending from the reinforcing plate.

[0059] The circuit board 100 includes a shielding cover and a reinforcing plate. The cover plate 120 , the shielding cover and the reinforcing plate are an integrated structure.

[0060] like Figure 2 As shown in FIG. 1 , as a possible implementation, a plurality of cover plates 120 are connected to a connector 130. Specifically, a connector 130 can be connected to a plurality of cover plates 120, and the plurality of cover plates 120 can be arranged in a stacked manner or in different regions, that is, different cover plates 120 are connected to different parts of the connector 130.

[0061] The plurality of cover plates 120 may be integrated with different shielding covers, or may be integrated with different reinforcing plates, or may be integrated with different shielding covers and reinforcing plates.

[0062] Specifically, the two cover plates 120 may form different sides of the through hole 124 , and may also form different side walls of the limiting groove 122 .

[0063] like Figure 4 As shown, as a possible implementation, the cover plate 120 is arranged between the connector 130 and the substrate 110, and then the cover plate 120 can be welded or bonded to the substrate 110 through the first connecting material 142, and the connector 130 and the cover plate 120 are welded or bonded through the second connecting material 144. Specifically, a laser welding process can be used between the connector 130 and the cover plate 120, and then laser welding can improve the connection strength of the two components, that is, improve the connection strength between the connector 130 and the cover plate 120. However, due to material limitations, the substrate 110 cannot adopt such a high-strength connection method, and then the risk of the connector 130 falling off is reduced by directly connecting the connector 130 and the cover plate 120.

[0064] like Figure 5As shown, as a possible implementation, a limiting groove 122 and a through hole 124 are provided on the cover plate 120, the connecting portion 132 of the connector 130 is passed through the through hole 124, and the head 134 is embedded in the limiting groove 122, and the side of the head 134 facing the substrate 110 is connected to the substrate 110 through the first connecting material 142, and the cover plate 120 on the peripheral side of the opening of the limiting groove 122 is also connected to the substrate 110 through the first connecting material 142, thereby limiting the connector 130 through the cover body and the connection between the substrate 110 and the connector 130, and the connection strength between the cover plate 120 and the substrate 110 as a whole and the connector 130 is improved, thereby reducing the risk of the connector 130 falling off.

[0065] like Figure 6 As shown, as a possible implementation, the cover plate 120 is bent into a two-layer structure, and a limiting groove 122 and a through hole 124 are provided on a layer close to the substrate 110, the connecting portion 132 of the connector 130 is passed through the through hole 124, and the head 134 is embedded in the limiting groove 122, and the side of the head 134 facing the substrate 110 is connected to the substrate 110 through the first connecting material 142, and the cover plate 120 on the peripheral side of the opening of the limiting groove 122 is also connected to the substrate 110 through the first connecting material 142, and the side of the connecting portion 132 facing away from the substrate 110 is connected to a layer of the cover plate 120 away from the substrate 110 through the second connecting material 144, thereby limiting the connector 130 through the cover body, and the connection between the substrate 110, the cover plate 120 and the connector 130 is jointly improved, and the risk of the connector 130 falling off is reduced.

[0066] like Figure 7 As shown, as a possible implementation, a limiting groove 122 and a through hole 124 are provided on the cover plate 120, the connecting portion 132 of the connector 130 is passed through the through hole 124, and the head 134 is embedded in the limiting groove 122, and the side of the head 134 facing the substrate 110 is connected to the substrate 110 through the first connecting material 142, the cover plate 120 on the peripheral side of the opening of the limiting groove 122 is also connected to the substrate 110 through the first connecting material 142, and the side of the head 134 facing away from the substrate 110 is connected to the bottom wall of the limiting groove 122 through the second connecting material 144, thereby limiting the connector 130 through the cover body, and the connection between the substrate 110, the cover plate 120 and the connector 130 is jointly improved, and the connection strength between the cover plate 120 and the substrate 110 as a whole and the connector 130 is reduced, thereby reducing the risk of the connector 130 falling off.
