[0045] In the following, the present application will be described in detail.

[0046] The existing circuit board level power supply is usually powered from a dedicated power supply layer, but when the circuit board is large in size and the power consumption of the components on the circuit board is unevenly distributed, it is necessary to design separate power supply for the local area with high power consumption demand. Usually, the number or thickness of internal wiring layers of the circuit board is increased to achieve this. This results in an increase in the overall number of layers of the circuit board and an increase in the thickness of the board, making the manufacturing of the circuit board more difficult and the manufacturing cost of the circuit board high.

[0047] The inventors of the present application have found through research that by installing a conductive mounting seat on the circuit board and connecting the conductive part to the conductive mounting seat through plug-in connection, the conductive part is electrically connected to the circuit board. The current of the circuit board can be conducted to other positions of the circuit board or to other components through the conductive mounting seat and the conductive part, which helps to reduce the circuits in the circuit board, simplify the design and processing difficulty of the circuit board, and thus reduce the manufacturing cost of the circuit board. Moreover, the plug-in connection can eliminate welding, making the processing process simpler, thereby effectively reducing the processing difficulty and saving the processing cost, and having good processing cost efficiency.

[0048] Based on such design concept, the inventors of the present application have designed a circuit board assembly, which comprises a circuit board, at least two conductive mounting seats and at least one conductive part. The conductive mounting seat is connected to the circuit board, and each conductive mounting seat forms a first conductive plug-in structure. The conductive part comprises a conductive main body part and at least two second conductive plug-in structures connected to the conductive main body part, and each first conductive plug-in structure is plugged with at least one second conductive plug-in structure.

[0049] The design installs the conductive mounting seat on the circuit board, the conductive mounting seat is electrically connected with the circuit board, the second conductive plug-in structure of the conductive part is plugged with the first conductive plug-in structure of the conductive mounting seat, so that the conductive part is electrically connected with the conductive mounting seat, therefore, the current of the circuit board can conduct current to other positions of the circuit board or conduct current to other components through the conductive mounting seat and the conductive main body part, which is beneficial to reduce the circuit in the circuit board, simplify the design and processing difficulty of the circuit board. And, the plug-in mode can save welding, so that the processing technology is simpler, thereby effectively reducing the processing difficulty and saving the processing cost, and having good processing cost benefit. In addition, the welding process is saved, which can reduce the risk of damage to the components of the circuit board caused by high-temperature welding. And, due to the setting of the conductive mounting seat, the conductive part is indirectly connected with the circuit board, which reduces the probability of wear of the circuit board caused by the plug-in of the conductive part, and is beneficial to prolong the service life of the circuit board.

[0050] The technical solutions described in the embodiments of the application are applicable to any electronic device that needs to use a circuit board, for example, a smart phone, a tablet computer, a smart hand, a television, a sound, a game machine, a robot driving board, a motor control board, etc.

[0053] A first aspect of the present application provides a circuit board assembly, such as Figures 1 to 3 As shown, the circuit board assembly comprises a circuit board 1, at least two electrically conductive mounting seats 2 connected to the circuit board 1, and at least one electrically conductive piece 3, the electrically conductive mounting seat 2 is formed with a first electrically conductive plug-in structure 21, the electrically conductive piece 3 comprises an electrically conductive main body part 31 and at least two second electrically conductive plug-in structures 32 connected to the electrically conductive main body part 31, and each first electrically conductive plug-in structure 21 is plugged with at least one second electrically conductive plug-in structure 32.

[0054] For example, the second electrically conductive plug-in structure 32 of the electrically conductive piece 3 is plugged into the electrically conductive mounting seat 2 along the thickness direction of the circuit board 1, and the electrically conductive main body part 31 is located on one side of the circuit board 1 along the thickness direction, and the side of the circuit board 1 facing the electrically conductive main body part 31 is provided with a component 6.

[0055] The circuit board 1 (PCB) can be referred to as a printed wiring board or a printed circuit board, and its core function is to realize component connection and signal transmission through the combination of an insulating substrate and a conductive circuit. The circuit board 1 comprises a substrate layer, a conductive layer and a protective layer.

[0056] The electrically conductive mounting seat 2 is a mechanical component connected to the circuit board 1 and electrically connected to the conductive layer of the circuit board 1. The electrically conductive mounting seat 2 can be connected to the circuit board 1 by plugging, welding or screwing, etc. The electrically conductive mounting seat 2 has a first electrically conductive plug-in structure 21, which is plugged with the second electrically conductive plug-in structure 32 of the electrically conductive piece 3, realizing the mutual plugging of the electrically conductive mounting seat 2 and the electrically conductive piece 3, fixing the position of the electrically conductive piece 3, and realizing the electrical connection between the electrically conductive piece 3 and the circuit board 1. The material of the electrically conductive mounting seat 2 can be, but is not limited to, copper, copper alloy, aluminum alloy, copper-steel composite structure, etc.

[0057] The electrically conductive piece 3 is a mechanical component with electrical conductivity. The second electrically conductive plug-in structure 32 of the electrically conductive piece 3 can be plugged with the first electrically conductive plug-in structure 21 of the electrically conductive mounting seat 2, so that the electrically conductive piece 3 is installed on the circuit board 1 through the electrically conductive mounting seat 2, and the electrically conductive piece 3 is electrically connected with the electrically conductive mounting seat 2, so that the electrically conductive piece 3 is electrically connected with the circuit board 1, and the current of the circuit board 1 can be conducted to other positions of the circuit board 1 or other components through the electrically conductive mounting seat 2 and the electrically conductive piece 3. For example, the electrically conductive main body part 31 of the electrically conductive piece 3 is in a long strip structure, which can be a flat long strip structure or a long strip structure with a circular cross section. The material of the electrically conductive piece 3 can be, but is not limited to, copper, copper alloy, aluminum alloy, copper-steel composite structure, etc.

[0058] It can be understood that the conductive part 3 is inserted into the conductive mounting seat 2 installed on the circuit board 1 by means of insertion, so that the conductive part 3 can be inserted into the conductive mounting seat 2 after the operation of welding the components 6 on the circuit board 1 is completed, and the installation of the conductive part 3 on the circuit board 1 is realized.

[0059] It should be noted that in the case of one or more conductive parts 3, all second conductive insertion structures 32 of the same conductive part 3 can be inserted into the conductive mounting seat 2 connected to the circuit board 1; in the case of multiple conductive parts 3, part of the second conductive insertion structures 32 of the same conductive part 3 can be inserted into the conductive mounting seat 2 connected to the circuit board 1, and the remaining second conductive insertion structures 32 are connected to another conductive part 3; and multiple second conductive insertion structures 32 of part of the conductive parts 3 can be connected to other different conductive parts 3, respectively.

[0060] In the embodiments of the present application, the conductive mounting seat 2 is installed on the circuit board 1, the conductive mounting seat 2 is electrically connected to the circuit board 1, the second conductive insertion structure 32 of the conductive part 3 is inserted into the first conductive insertion structure 21 of the conductive mounting seat 2, so that the conductive part 3 is electrically connected to the conductive mounting seat 2, and thus the current of the circuit board 1 can be conducted to other positions of the circuit board 1 or other components through the conductive mounting seat 2 and the conductive main body 31, which is beneficial to reduce the circuit in the circuit board 1 and simplify the design and processing difficulty of the circuit board 1. Moreover, the insertion mode can save the welding, so that the processing technology is simpler, thereby effectively reducing the processing difficulty and saving the processing cost, and having good processing cost benefit. In addition, the welding process is saved, which can reduce the risk of damage to the components 6 of the circuit board 1 caused by high-temperature welding of the conductive part 3. Moreover, due to the arrangement of the conductive mounting seat 2, the conductive part 3 is indirectly connected to the circuit board 1, which reduces the probability of wear of the circuit board 1 caused by the insertion of the conductive part 3, and is beneficial to prolong the service life of the circuit board 1.

[0061] It should be noted that the conductive mounting seat 2 can be connected to the circuit board 1 after the components 6 are welded on the circuit board 1, for example, in the case that the conductive mounting seat 2 is connected to the circuit board 1 by means of insertion without heating, the conductive mounting seat 2 can be connected to the circuit board 1 after the components 6 are welded. The conductive mounting seat 2 can also be connected to the circuit board 1 before the components 6 are welded on the circuit board 1, for example, in the case that the conductive mounting seat 2 is connected to the circuit board 1 by means of welding, the conductive mounting seat 2 is welded on the circuit board 1 before the components 6 are welded, which can reduce the damage to the components 6 caused by welding of the conductive mounting seat 2.

[0062] In some embodiments of the present application, as Figure 3 and Figure 4As shown, one of the first and second conductive plug structures 21 and 32 is a plug groove 21a, and the other is a plug protrusion 32a which is plugged with the plug groove 21a.

[0063] As shown, the first conductive plug structure 21 is the plug groove 21a, and the second conductive plug structure 32 is the plug protrusion 32a which is plugged with the plug groove 21a. Figure 3 Figure 4 As shown, the first conductive plug structure 21 is the plug groove 21a, and the second conductive plug structure 32 is the plug protrusion 32a which is plugged with the plug groove 21a.

[0064] As shown, the first conductive plug structure 21 is the plug groove 21a, and the second conductive plug structure 32 is the plug protrusion 32a which is plugged with the plug groove 21a.

[0065] In this way, the first and second conductive plug structures 21 and 32 are plugged and connected with each other, the connection operation of the conductive member 3 and the conductive mounting seat 2 is simplified, the connection difficulty is reduced, and the manufacturing cost is lowered.

[0066] As shown, the first conductive plug structure 21 is the plug groove 21a, and the second conductive plug structure 32 is the plug protrusion 32a which is plugged with the plug groove 21a.

[0067] In some embodiments of the present application, the plug protrusion 32a and the plug groove 21a are in interference fit.

[0068] It can be understood that the fit of the plug protrusion 32a and the plug groove 21a is not limited to interference fit. Alternatively, the plug protrusion 32a and the plug groove 21a are in clearance fit or transition fit, the clearance is controlled in a relatively small range, and the relative position of the two can be fixed.

[0069] In some embodiments of the present application, as shown, the surface of the plug protrusion 32a which contacts the plug groove 21a and / or the surface of the plug groove 21a which contacts the plug protrusion 32a is provided with a first conductive plating layer 51. Figure 4

[0070] As shown, the first conductive plug structure 21 is the plug groove 21a, and the second conductive plug structure 32 is the plug protrusion 32a which is plugged with the plug groove 21a.

[0071] ​​For example, at least part of the region of the entire surface of the insertion protrusion 32a that contacts the insertion slot 21a is provided with a first conductive plating layer 51.

[0072] For example, at least part of the region of the entire slot wall of the insertion slot 21a that contacts the insertion protrusion 32a is provided with a first conductive plating layer 51.

[0073] For example, the first conductive plating layer 51 includes at least one of a gold plating layer, a silver plating layer, and a nickel plating layer.

[0074] By plating the contact region between the insertion protrusion 32a and the insertion slot 21a, the contact impedance can be reduced, the electrical conductivity can be improved, and the electrical reliability of the circuit board assembly can be improved.

[0075] It can be understood that the present application is not limited to both the insertion protrusion 32a and the insertion slot 21a being provided with the first conductive plating layer 51. The insertion protrusion 32a and the insertion slot 21a can also not be provided with the first conductive plating layer 51. One of the insertion protrusion 32a and the insertion slot 21a can be provided with the first conductive plating layer 51, and the other can not be provided with the first conductive plating layer 51.

[0076] In some embodiments of the present application, as shown in Figure 5 and Figure 6 The first conductive insertion structure 21 is the insertion slot 21a, the second conductive insertion structure 32 is the insertion protrusion 32a that is inserted into the insertion slot 21a, each conductive mounting seat 2 is formed with a protruding portion 22 on the side opposite to the insertion slot 21a, the circuit board 1 is formed with a mounting hole 11, and the protruding portion 22 is inserted into the mounting hole 11.

[0077] For example, part of each conductive mounting seat 2 is deformed to protrude toward the side on which the circuit board 1 is arranged, the protruding portion 22 is formed on the side toward the circuit board 1, and the insertion slot 21a is formed on the side away from the circuit board 1.

[0078] For example, the cross section of the outer contour of the protruding portion 22 can be, but is not limited to, a circle, an ellipse, a polygon, or other regular or irregular shapes. Correspondingly, the cross section of the mounting hole 11 can be, but is not limited to, a circle, an ellipse, a polygon, or other regular or irregular shapes. The cross section is a cross section perpendicular to the thickness direction of the circuit board 1. It can be understood that the cross sections of different positions of the outer contour of the protruding portion 22 can be the same or different. The cross sections of different positions of the mounting hole 11 can be the same or different. As long as the protruding portion 22 and the mounting hole 11 are matched and can limit the relative positions of the two after being inserted, the specific shapes of the two are not limited herein.

[0079] Thus, the back side of the insertion slot 21a forms the protruding portion 22, which not only enables the electrically-conductive mounting seat 2 to be connected to the circuit board 1 through the protruding portion 22 and the mounting hole 11, but also facilitates reducing the volume of the electrically-conductive mounting seat 2 and saving space. The electrically-conductive mounting seat 2 is connected to the circuit board 1 through insertion, which enables the contact area between the electrically-conductive mounting seat 2 and the circuit board 1 to be relatively large, thereby improving the reliability of mechanical connection and electrical connection. In addition, the electrically-conductive mounting seat 2 is connected to the circuit board 1 through insertion, which enables the electrically-conductive mounting seat 2 to be installed after the components 6 are welded, and then the electrically-conductive member 3 is inserted and mounted. Thus, the installation operation is further simplified, and the damage to the components 6 is further reduced.

[0080] It can be understood that the connection mode of the electrically-conductive mounting seat 2 and the circuit board 1 is not limited to insertion, but can also be bolt connection, welding, etc., which is not specifically limited herein.

[0081] In some embodiments of the present application, as shown in Figure 5 and Figure 6 The electrically-conductive mounting seat 2 further includes an abutting portion 23 surrounding the protruding portion 22, and the abutting portion 23 abuts against the surface of the circuit board 1 facing the electrically-conductive body portion 31.

[0082] It should be noted that part of the electrically-conductive mounting seat 2 protrudes and deforms toward the side provided with the circuit board 1, and the protruding portion 22 is formed on the side facing the circuit board 1, and the insertion slot 21a is formed on the side away from the circuit board 1, and the remaining part of the electrically-conductive mounting seat 2 forms the abutting portion 23 surrounding the protruding portion 22.

[0083] For example, the electrically-conductive mounting seat 2 is made of a plate material through a stamping process.

[0084] Through the arrangement of the abutting portion 23, the contact area between the electrically-conductive mounting seat 2 and the circuit board 1 is improved, and the connection reliability of the electrically-conductive mounting seat 2 and the circuit board 1 is improved.

[0085] In some embodiments of the present application, as shown in Figure 7 The circuit board assembly further includes a spacer 4, which is detachably sleeved on the outer periphery of the insertion protrusion 32a and abuts between the abutting portion 23 and the electrically-conductive body portion 31.

[0086] Thus, by arranging the spacer 4 between the abutting portion 23 and the electrically-conductive body portion 31, the spacing between the electrically-conductive body portion 31 and the circuit board 1 can be changed, so that the side of the circuit board 1 facing the electrically-conductive body portion 31 can be provided with components 6 of different sizes, thereby improving the application range of the electrically-conductive member 3.

[0087] For example, the plurality of spacers 4 are provided, and all the spacers 4 have at least two different thicknesses. At least one of the spacers 4 is selected to be sleeved on the insertion protrusion 32a, so that the conductive main body 31 is adjusted to be located at a plurality of positions with different distances from the circuit board 1 to adapt to different use scenarios.

[0088] In some embodiments of the present application, the protrusion 22 is in interference fit with the mounting hole 11.

[0089] It can be understood that the fit between the protrusion 22 and the mounting hole 11 is not limited to interference fit. Alternatively, the insertion protrusion 32a and the insertion groove 21a are in clearance fit or transition fit, and the clearance is controlled in a relatively small range, which can fix the relative positions of the two, and is not limited here.

[0090] In some embodiments of the present application, as shown in Figure 6 The surface of the protrusion 22 in contact with the mounting hole 11 and / or the surface of the mounting hole 11 in contact with the protrusion 22 is provided with a second conductive plating layer 52.

[0091] For example, at least part of the surface of the protrusion 22 in contact with the mounting hole 11 is provided with the second conductive plating layer 52.

[0092] For example, at least part of the surface of the protrusion 22 in contact with the mounting hole 11 is provided with the second conductive plating layer 52.

[0093] For example, at least part of the surface of the protrusion 22 in contact with the mounting hole 11 is provided with the second conductive plating layer 52.

[0094] For example, the second conductive plating layer 52 includes at least one of a gold plating layer, a silver plating layer, and a nickel plating layer.

[0095] By plating the contact part between the protrusion 22 and the mounting hole 11, the contact resistance can be reduced, the electrical conductivity can be improved, and the electrical reliability of the circuit board assembly can be improved.

[0096] In some embodiments of the present application, the conductive main body 31 and the insertion protrusion 32a are formed in an integral structure.

[0097] In this way, the connection reliability of the conductive main body 31 and the insertion protrusion 32a is improved, the conductive resistance is reduced, the electrical conductivity is improved, and the manufacturing efficiency of the conductive member 3 is high.

[0098] It can be understood that the conductive main body 31 and the insertion protrusion 32a are not limited to the integral structure, but can also be connected by welding, etc. Herein, no specific limitation is made.

[0099] In some embodiments of the present application, the difference between the size of the protrusion 22 and the size of the mounting hole 11 in any direction perpendicular to the thickness direction of the circuit board 1 is greater than or equal to 0.2 mm and less than or equal to 0.5 mm.

[0100] For example, the outer circumferential surface of the protrusion 22 and the hole wall of the mounting hole 11 are both circular in cross section, and the difference between the diameter of the outer circumferential surface of the protrusion 22 and the diameter of the hole wall of the mounting hole 11 is greater than or equal to 0.2 mm and less than or equal to 0.5 mm.

[0101] For example, the difference between the size of the protrusion 22 and the size of the mounting hole 11 in any direction perpendicular to the thickness direction of the circuit board 1 can be, but is not limited to, 0.2 mm, 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm, 0.25 mm, 0.26 mm, 0.27 mm, 0.28 mm, 0.29 mm, 0.3 mm, 0.31 mm, 0.32 mm, 0.33 mm, 0.34 mm, 0.35 mm, 0.36 mm, 0.37 mm, 0.38 mm, 0.39 mm, 0.4 mm, 0.41 mm, 0.42 mm, 0.43 mm, 0.44 mm, 0.45 mm, 0.46 mm, 0.47 mm, 0.48 mm, 0.49 mm, 0.5 mm.

[0102] In this way, the protrusion 22 and the mounting hole 11 are in interference fit, and the two can be firmly inserted together, and it is also not easy to insert the protrusion 22 into the mounting hole 11 due to the difference being too large, thereby improving the smoothness of the insertion operation.

[0103] In some embodiments of the present application, as shown in Figure 2 and Figure 3 the conductive main body portion 31 is in a flat structure, and the thickness direction of the conductive main body portion 31 is consistent with the thickness direction of the circuit board 1.

[0104] It can be understood that the flat structure refers to a structure with a thickness much smaller than its length and width dimensions, including a plate-like or sheet-like structure. The conductive main body portion 31 is in a flat structure, and the thickness direction of the conductive main body portion 31 is consistent with the thickness direction of the circuit board 1, i.e., the conductive main body portion 31 is parallel to the circuit board 1.

[0105] For example, as shown in Figure 2 and Figure 3 the conductive main body portion 31 is in a flat strip structure, and each end of the strip structure along its length direction is provided with an insertion protrusion 32a. The insertion protrusions 32a are provided on the same side of the conductive main body portion 31 along its thickness direction.

[0106] Thus, by arranging the conductive main body 31 to be parallel to the circuit board 1, the influence of the conductive main body 31 on the heat dissipation air duct is reduced, and the heat dissipation effect is improved.

[0107] In some embodiments of the present application, as shown in Figures 8 to 10 The conductive member 3 is provided with two or more conductive members 3, and the conductive main body 31 of at least one conductive member 3 is formed with a plurality of third conductive plug-in structures 311 arranged at intervals, and each third conductive plug-in structure 311 of the conductive member 3 can be plugged into any second conductive plug-in structure 32 of another conductive member 3.

[0108] For example, the conductive main body 31 is a flat long strip structure, and the long strip structure is provided with a plurality of third conductive plug-in structures 311 arranged at intervals along the length direction.

[0109] For example, the second conductive plug-in structure 32 is a plug-in protrusion 32a, and the third conductive plug-in structure 311 is a plug-in hole 311a, and the plug-in protrusion 32a can be plugged into the plug-in hole 311a.

[0110] For example, the second conductive plug-in structure 32 is a plug-in slot 21a, and the third conductive plug-in structure 311 is a protruding structure, and the protruding structure can be plugged into the plug-in slot 21a.

[0111] Thus, a plurality of conductive members 3 can be connected to facilitate the use of a plurality of conductive members 3 for power supply topology of the circuit board 1, and a variety of different conductive structures can be flexibly formed.

[0112] It can be understood that the number of conductive members 3 is not limited to two or more, but can also be one.

[0113] In embodiments of the present application, the plurality of means two or more.

[0114] In some embodiments of the present application, as shown in Figure 8 The third conductive plug-in structure 311 is a plug-in hole 311a, and the second conductive plug-in structure 32 is a plug-in protrusion 32a matched with the third conductive plug-in structure 311.

[0115] Thus, the structure of the conductive member 3 is simple, the manufacturing cost is low, and the connection operation between the conductive members 3 is convenient, and the connection reliability is high.

[0116] For example, the size of each conductive member 3 is the same, that is, the shape of the conductive member 3 and the size in each direction are the same.

[0117] For example, the size of at least two conductive members 3 is different, that is, the shape of the conductive member 3 or the size in at least one direction is different.

[0118] For example, the spacing between adjacent insertion holes 311a is set to be the same.

[0119] For example, the spacing between adjacent insertion holes 311a is set to be different.

[0120] For example, such as Figure 9 As shown, there are four or more conductive elements 3. Each conductive element 3 has a plug-in protrusion 32a at both ends. The conductive body 31 of the conductive element 3 has multiple plug-in holes 311a. The two plug-in protrusions 32a of the first conductive element 3 are respectively plugged into the two conductive mounting bases 2 on the circuit board 1. One plug-in protrusion 32a of the second conductive element 3 is plugged into one plug-in hole 311a of the first conductive element 3. One plug-in protrusion 32a of the third conductive element 3 is plugged into one plug-in hole 311a of the second conductive element 3. One plug-in protrusion 32a of the fourth conductive element 3 is plugged into another plug-in hole 311a of the second conductive element 3. The other plug-in protrusion 32a of the second, third, and fourth conductive elements 3 can be plugged into the conductive mounting bases 2 on the circuit board 1 or into the plug-in holes 311a of other conductive elements 3. In this way, various different conductive structures can be formed. The specific structure formed can be determined according to the connection requirements and is not specifically limited here.

[0121] For example, such as Figure 10 As shown, there are three or more conductive elements 3. Each conductive element 3 has a plugging protrusion 32a at both ends. At least one conductive element 3 has a conductive body 31 with multiple plugging holes 311a. The first conductive element 3 has multiple plugging holes 311a. Two plugging protrusions 32a of the first conductive element 3 are respectively plugged into two conductive mounting bases 2 on the circuit board 1. One plugging protrusion 32a of the second conductive element 3 is plugged into one plugging hole 311a of the first conductive element 3. One plugging protrusion 32a of the third conductive element 3 is plugged into another plugging hole 311a of the first conductive element 3. The other plugging protrusions 32a of the second and third conductive elements 3 can be plugged into the conductive mounting bases 2 on the circuit board 1 or into the plugging holes 311a of other conductive elements 3. In this way, various different conductive structures can be formed. The specific structure formed can be determined according to the connection requirements and is not specifically limited here.

[0122] In some embodiments of this application, the conductive element 3 includes two second conductive plug-in structures 32, and at least a portion of the third conductive plug-in structure 311 is arranged between the two second conductive plug-in structures 32.

[0123] Exemplarily, the two second conductive plug structures 32 are respectively arranged at opposite ends of the conductive main body 31 along the length direction thereof, and all the third conductive plug structures 311 are arranged between the two second conductive plug structures 32 along the length direction of the conductive main body 31.

[0124] In this way, the connection between the conductive members 3 can be made in a larger range, and the current conduction can be realized in a longer distance.

[0125] In some embodiments of the present application, as shown in Figure 11 and Figure 12 The conductive main body 31 comprises a first part 312 and a second part 313, the first part 312 has a sliding cavity 3121 extending along the first direction, the first part 312 is provided with the second conductive plug structure 32 at one end along the first direction, the other end of the sliding cavity 3121 along the first direction is formed with an opening, one end of the second part 313 is movably inserted into the sliding cavity 3121 along the first direction through the opening, and the other end of the second part 313 is provided with the second conductive plug structure 32.

[0126] Exemplarily, the first part 312 and the plug protrusion 32a connected thereto are formed in an integral molding structure. Alternatively, the first part 312 and the plug protrusion 32a connected thereto are connected by welding.

[0127] Exemplarily, the second part 313 and the plug protrusion 32a connected thereto are formed in an integral molding structure. Alternatively, the second part 313 and the plug protrusion 32a connected thereto are connected by welding.

[0128] In this way, by inserting or extracting the second part 313 into or out of the sliding cavity 3121 along the first direction, the size of the conductive main body 31 along the first direction can be adjusted, so that the distance between the second conductive plug structures 32 at opposite ends of the conductive main body 31 can be adjusted, and the distance of current transmission can be adjusted, so as to expand the application scenarios of the conductive member 3.

[0129] It can be understood that the conductive main body 31 is not limited to the structure with adjustable length, but can also be a structure with fixed size.

[0130] In some embodiments of the present application, as shown in Figure 11 The cavity wall of the sliding cavity 3121 is provided with an elastic clamping piece 3124, the second part 313 is provided with a plurality of clamping grooves 3132 distributed at intervals along the first direction, and the elastic clamping piece 3124 is clamped with one of the clamping grooves 3132.

[0131] Exemplarily, the elastic clamping piece 3124 is a metal spring piece.

[0132] After the first part 312 is moved to a suitable position along the first direction, the relative position of the first part 312 and the second part 313 is fixed by the clamping of the elastic clamping part 3124 and the clamping groove 3132, the length of the conductive main part 31 is locked, the distance of the current transmission is adjusted, and the application scenarios of the conductive part 3 are expanded.

[0133] In some embodiments of the present application, as shown in Figure 13 One of the cavity wall of the sliding cavity 3121 and the outer peripheral surface of the second part 313 is provided with an elastic protrusion 3122, and the other is in elastic abutment with the elastic protrusion 3122.

[0134] Exemplarily, the elastic protrusion 3122 is a metal spring.

[0135] Exemplarily, the sliding cavity 3121 and the second part 313 are provided with a third conductive plating layer 53 at the part where the elastic protrusion 3122 contacts.

[0136] Through the provision of the elastic protrusion 3122, the cavity wall of the sliding cavity 3121 and the outer peripheral surface of the second part 313 are tightly fitted, the contact is good, the contact impedance is reduced, and the electrical conductivity is improved.

[0137] In some embodiments of the present application, as shown in Figure 13 One of the cavity wall of the sliding cavity 3121 and the outer peripheral surface of the second part 313 is provided with a sliding groove 3123 extending along the first direction, and the other is provided with a sliding protrusion 3131 extending along the first direction, and the sliding protrusion 3131 is slidingly fitted in the sliding groove 3123.

[0138] Exemplarily, the sliding protrusion 3131 is provided with one, two, three or more, and correspondingly, the sliding groove 3123 is provided with one, two, three or more.

[0139] Exemplarily, the surface of the sliding protrusion 3131 and the groove wall of the sliding groove 3123 are both provided with a third conductive plating layer 53.

[0140] In this way, through the cooperation of the sliding protrusion 3131 and the sliding groove 3123, the sliding connection of the first part 312 and the second part 313 along the first direction is realized, the stability of the connection of the two is improved. Moreover, the cooperation of the sliding protrusion 3131 and the sliding groove 3123 also increases the contact area between the first part 312 and the second part 313, reduces the contact impedance, and reduces the impedance of the entire conductive part 3.

[0141] In some embodiments of the present application, as shown in Figure 13 At least part of the cavity wall of the sliding cavity 3121 and at least part of the outer peripheral surface of the second part 313 are in contact, and at least one of the surfaces in contact is provided with a third conductive plating layer 53.

[0142] For example, the third conductive plating layer 53 includes at least one of a gold plating layer, a silver plating layer, and a nickel plating layer.

[0143] By plating the contact position between the cavity wall of the sliding cavity 3121 and the outer circumferential surface of the second part 313, the contact impedance can be reduced, the electrical conductivity can be improved, and the electrical reliability of the circuit board assembly can be improved.

[0144] Of course, it can be understood that the cavity wall of the sliding cavity 3121 and the outer circumferential surface of the second part 313 are not limited to this. The contact surfaces of the cavity wall of the sliding cavity 3121 and the second part 313 can also be free of the third conductive plating layer 53.

[0145] In some embodiments of the present application, as shown in Figure 13 One of the two cavity walls of the sliding cavity 3121 opposite in the thickness direction of the first part 312 is formed with an elastic protrusion 3122, and the other is formed with a sliding protrusion 3131. The elastic protrusion 3122 elastically abuts against one surface of the second part 313, and the sliding protrusion 3131 is in sliding cooperation with a sliding groove 3123 provided on the other surface of the second part 313.

[0146] In this way, the opposite sides of the second part 313 in the thickness direction thereof are in contact with the sliding cavity 3121, improving the stability of the sliding connection between the first part 312 and the second part 313, increasing the contact area, improving the reliability of the electrical connection, and improving the electrical conductivity.

[0147] The second aspect of the present application provides a circuit board conductive accessory, as shown in Figures 1 to 3 The circuit board conductive accessory includes at least two conductive mounting seats 2 and at least one conductive piece 3. The conductive mounting seat 2 is used for connection to the circuit board 1. Each conductive mounting seat 2 is formed with a first conductive plug-in structure 21. The conductive piece 3 includes a conductive main body part 31 and at least two second conductive plug-in structures 32 connected to the conductive main body part 31. Each first conductive plug-in structure 21 is in plug-in cooperation with at least one second conductive plug-in structure 32.

[0148] The second conductive plug structure 32 of the conductive part 3 is plugged with the first conductive plug structure 21 of the conductive mounting base 2, so that the conductive part 3 is electrically connected with the conductive mounting base 2, thus the current of the circuit board 1 can be conducted to other positions of the circuit board 1 or other components through the conductive mounting base 2 and the conductive main body part 31, which is beneficial to reduce the circuit of the circuit board 1 and simplify the design and processing difficulty of the circuit board 1. Moreover, the plug-in mode can save welding, so that the processing technology is simpler, thereby effectively reducing the processing difficulty and saving the processing cost, which has good processing cost benefit. In addition, the welding process is saved, which can reduce the risk of damage to the components 6 of the circuit board 1 caused by high-temperature welding. Moreover, due to the arrangement of the conductive mounting base 2, the conductive part 3 is indirectly connected with the circuit board 1, compared with the direct plug-in mode of the conductive part 3 and the circuit board 1, the indirect connection reduces the probability of wear of the conductive part 3 on the circuit board 1, which is beneficial to prolong the service life of the circuit board 1.

[0149] In some embodiments of the present application, as shown in Figures 4 to 6 The circuit board 1 is formed with a mounting hole 11, the first conductive plug structure is a plug-in slot 21a, the second conductive plug structure 32 is a plug-in protrusion 32a plugged with the plug-in slot 21a, and each conductive mounting base 2 is formed with a protruding part 22 on the side opposite to the plug-in slot 21a, which is plugged with the mounting hole 11.

[0150] For example, part of each conductive mounting base 2 is deformed to protrude towards the side of the circuit board 1, and a protruding part 22 is formed on the side towards the circuit board 1, and a plug-in slot 21a as the first conductive plug structure 21 is formed on the side away from the circuit board 1.

[0151] In this way, the conductive part 3 can be plugged with the plug-in slot 21a of the conductive mounting base 2 through the plug-in protrusion 32a of the conductive part 3, realizing the connection of the conductive part 3 and the conductive mounting base 2, thereby realizing the indirect connection of the conductive part 3 and the circuit board 1, and the current of the circuit board 1 can be conducted to other positions of the circuit board 1 or other components through the conductive part 3, which is beneficial to reduce the circuit of the circuit board 1 and simplify the design and processing difficulty of the circuit board 1.

[0152] In some embodiments of the present application, as shown in Figures 8 to 10 The conductive part 3 is provided with two or more conductive main body parts 31, and at least one conductive main body part 31 is formed with a plurality of plug-in holes 311a arranged at intervals, and each plug-in hole 311a of the conductive part 3 can be plugged with any plug-in protrusion 32a of another conductive part 3.

[0153] In this way, the plurality of conductive members 3 can be connected to facilitate the power supply topology of the circuit board 1 using the plurality of conductive members 3, and various different conductive structures can be flexibly formed. The conductive member 3 has a simple structure, low manufacturing cost, and the connection operation between the conductive members 3 is convenient and has high connection reliability.

[0154] In some embodiments of the present application, the conductive body part 31 includes a first part 312 and a second part 313. The first part 312 has a sliding cavity 3121 extending in the first direction. The first part 312 is provided with a second conductive plug-in structure 32 at one end in the first direction. The other end of the sliding cavity 3121 in the first direction is formed with an opening. One end of the second part 313 movably extends into the sliding cavity 3121 in the first direction through the opening. The other end of the second part 313 is provided with a second conductive plug-in structure 32. The cavity wall of the sliding cavity 3121 is provided with an elastic clamping member 3124. The second part 313 is provided with a plurality of clamping grooves 3132 spaced apart in the first direction. The elastic clamping member 3124 is clamped with one of the clamping grooves 3132.

[0155] In some embodiments of the present application, the conductive member 3 is made of copper material. The cross-sectional area of the conductive body part 31 of the conductive member 3 is greater than or equal to 0.1 mm 2 and less than or equal to 100 mm 2 .

[0156] It can be understood that the cross section of the conductive body part 31 is perpendicular to the length direction of the conductive body part 31.

[0157] For example, the cross-sectional area of the conductive body part 31 of the conductive member 3 can be, but is not limited to, 0.1 mm 2 , 1 mm 2 , 2 mm 2 , 3 mm 2 , 4 mm 2 , 5 mm 2 , 6 mm 2 , 7 mm 2 , 8 mm 2 , 9 mm 2 , 10 mm 2 , 20 mm 2 , 30 mm 2 , 40 mm 2 , 50 mm 2 , 60 mm 2 , 70 mm 2 , 80 mm 2 , 90 mm 2 , 100 mm 2 .

[0158] In some embodiments of this application, the conductive element 3 is made of copper, and the cross-sectional area of ​​the conductive main body 31 of the conductive element 3 is greater than or equal to 10 mm². 2 and less than or equal to 100 mm 2 .

[0159] In this way, the cross-sectional area of ​​the conductive body 31 is large enough to have a high current-carrying capacity, which can meet the demand for high current and reduce energy loss. Furthermore, the cross-sectional area of ​​the conductive body 31 is not too large, which would cause problems such as large space occupation and material waste.

[0160] In some embodiments of this application, the outer surface of the conductive body portion 31 of the conductive element 3 is covered with an insulating layer.

[0161] For example, the insulating layer can be formed by coating with insulating varnish. The insulating layer can be an insulating sleeve fitted over the conductive body 31. The insulating layer can be an insulating material such as alumina or ceramic deposited on a copper surface by an electroplating process.

[0162] In this way, the risk of current leakage or short circuit caused by accidental contact between conductive component 3 and other conductive parts is reduced, and external factors such as moisture, dust, and chemical corrosion are resisted, thus extending the service life of conductive component 3.

[0163] In some embodiments of this application, the portion of the protrusion 22 of the conductive mounting base 2 that contacts the mounting hole 11 of the circuit board 1 has a dimension along the thickness direction of the circuit board 1 that is greater than or equal to 1.6 mm and less than or equal to 10 mm.

[0164] For example, the dimensions of the contact portion between the protrusion 22 of the conductive mounting base 2 and the mounting hole 11 of the circuit board 1 along the thickness direction of the circuit board 1 can be, but are not limited to, 1.6mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, and 10mm.

[0165] As a specific example, the outer peripheral surface of the protrusion 22 of the conductive mounting base 2 is provided with a gold plating layer, and the coefficient of friction between the gold plating layer and the material FR-4 (Flame-Retardant 4) of the hole wall of the mounting hole 11 of the circuit board 1 is... The elastic modulus of the substrate layer (material FR-4) of circuit board 1 is greater than or equal to 0.3 μm and less than or equal to 0.4 μm. The pressure is greater than or equal to 15 GPa and less than or equal to 20 GPa. The outer peripheral surface of the protrusion 22 of the conductive mounting base 2 and the cross-section of the hole wall of the mounting hole 11 are both circular. The difference between the diameter of the outer peripheral surface of the protrusion 22 and the diameter of the hole wall of the mounting hole 11 is... The thickness is greater than or equal to 0.2 mm and less than or equal to 0.5 mm. The crimping force between the conductive mounting base 2 and the circuit board 1 is F, and the formula for calculating F is: ,in, is the contact area, wherein is the dimension of the contact part between the protrusion 22 of the conductive mounting seat 2 and the mounting hole 11 of the circuit board 1 along the thickness direction of the circuit board 1, is the contact pressure, According to the above three formulas, it can be derived that wherein, is greater than or equal to 0.3 μm and less than or equal to 0.4 μm; is greater than or equal to 15 GPa and less than or equal to 20 GPa; is greater than or equal to 0.2 mm and less than or equal to 0.5 mm; is greater than or equal to 1.6 mm and less than or equal to 10 mm, thus, = 0.3 * 15 * 0.2 * 1.6 4.5 N, the crimping force F directly reflects the firmness of the clamping of the conductive mounting seat 2 and the circuit board 1, and the crimping force of the two is large enough to meet the demand of the insertion strength of the conductive mounting seat 2 on the circuit board 1.

[0166] The third aspect of the present application provides an electronic device, which comprises the circuit board assembly of the first aspect.

[0167] Since the processing cost of the circuit board assembly of the first aspect is low, and the risk of damage to the components 6 of the circuit board 1 is low, the processing cost of the electronic device comprising the circuit board assembly is low, and the risk of damage to the components 6 of the circuit board 1 is low.
