Description

Technical Field

[0001] The present application belongs to the technical field of electrical connectors, and in particular, relates to an electrical connection structure between circuit boards and an electronic atomization device. Background Art

[0002] The common electrical connection between circuit boards generally adopts a pin header connection structure, which connects the electrical connection parts of two circuit boards together by welding. However, since the spacing between the pin headers is relatively close, especially on small circuit boards, the spacing between the pin headers is even smaller, which makes it easy to cause the undesirable phenomenon of bridging during welding, thereby increasing the difficulty of welding and production costs.

[0003] It can be seen that the electrical connection structure used between circuit boards in the prior art still has many defects, which is a technical problem that electrical device manufacturers urgently need to solve. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide an electrical connection structure between circuit boards and an electronic atomization device to solve the technical problem that the electrical connection structure between circuit boards in the prior art is prone to bridging when welding, resulting in poor connection.

[0005] To achieve the above purpose, the technical solution adopted in this application is:

[0006] In a first aspect, an embodiment of the present application provides an electrical connection structure between circuit boards, including a first circuit board and a second circuit board, wherein the electrical connection structure includes:

[0007] An elastic sheet, wherein the elastic sheet has a buckling portion formed by bending;

[0008] A connector, arranged on the first circuit board, the connector is provided with a pin header and mounting grooves on both sides of the connector, the elastic sheet is detachably arranged in the mounting groove, and the extending end of the elastic sheet extends from the connector and is mounted on the first circuit board;

[0009] The second circuit board has a conductive component and slots on both sides of the conductive component, and the slots have buckle grooves for buckling the buckle parts on the elastic sheet; the conductive component is used to connect with the pin header on the connector, the elastic sheet is inserted into the slots, and the buckle parts are buckled with the buckle grooves.

[0010] The beneficial effect of the electrical connection structure provided by the present application is that: compared with the prior art, the electrical connection structure of the present application has a connector on the connection end of one circuit board, and the connector has a pin header and an elastic sheet for snap-on connection; a conductive component for connecting with the pin header and slots on both sides of the conductive component are provided on the connection end of the other circuit board. When the two circuit boards are connected, the connector is used to realize the plug-in installation connection, so that the pin header and the conductive component are plugged into each other, and at the same time, the elastic sheet is plugged into the slot on the side of the conductive component, so that the buckle part on the elastic sheet can be buckled with the buckle groove in the slot, thereby replacing the welding method, so that the two circuit boards can realize the plug-in installation connection, thereby improving the installation efficiency and convenience.

[0011] The electrical connection structure provided by the embodiment of the present application has a simple structure, and the connector can be set on the circuit board through the patch process, which is conducive to reducing the cost of using the welding process, thereby reducing the difficulty of production and the welding defect rate. For the elastic sheet on the connector, on the one hand, the elastic sheet serves as a snap-on member connected to another circuit board, so that the circuit boards can be connected through plug-in connection, thereby achieving rapid assembly and improving production efficiency; it is convenient to disassemble during rework and maintenance, reducing scrap and saving costs. On the other hand, the elastic sheet also serves as a positioning member to fix the connector on the circuit board, so that the connector is positioned on the end of the circuit board, which is convenient for interconnection with another circuit board as an electrical connector. Since there is no need to use welding or set a screw fixing structure, it is particularly conducive to installing such a connector on a small circuit board, effectively reducing the difficulty of processing and production costs.

[0012] As for the fixing structure between the connector and the first circuit board, a fixing hole corresponding to the position of the elastic sheet is provided on the first circuit board, and the extending end of the elastic sheet extends from the connector and is plugged into the fixing hole of the first circuit board. In this way, the connection method between the elastic sheet and the first circuit board is more concise and easy to implement, and the connector is effectively positioned on the first circuit board.

[0013] The structure on the connector is improved, and both sides of the connector also have slots extending from the installation slot to the outside. When the first circuit board is connected to the second circuit board, the board surface of the second circuit board adjacent to the slot is inserted into the slot at the same time. In this way, when the two boards are connected, the board surface of the second circuit board located on both sides of the slot can be plugged into the slot, and the board surface of the second circuit board is clamped and fixed by the slots on both sides of the connector, effectively improving the connection stability between the first circuit board and the second circuit board.

[0014] In one embodiment, the connector is further provided with a first chamfer located on the slotted notch, so that the slotted notch is guided and expanded, which is beneficial for installation alignment and further improves the assembly efficiency between the two circuit boards.

[0015] The structure of the elastic sheet is improved, the elastic sheet includes a frame and a buckling portion located on the frame, one side of the frame has an extended end of the elastic sheet; a through hole connected to the mounting groove is provided on the side of the connector away from the pin row, the extended end of the elastic sheet extends out from the through hole and is used to be fixed on the first circuit board.

[0016] In one embodiment, the connector is further provided with a limiting portion located in the installation groove, and the limiting portion is used to limit the insertion stroke of the frame. In this way, the elastic sheet is installed and positioned on the connector. After the elastic sheet is installed in place in the installation groove, only the extended end of the elastic sheet extends from the perforation on the back of the connector to connect with the first circuit board. In addition, after the elastic sheet is installed in place, the buckle portion on the elastic sheet can be matched with the buckle slot position in the slot on the second circuit board, which is conducive to ensuring the position matching accuracy of the snap connection.

[0017] In one embodiment, the buckling portion is disposed in the frame opening of the frame body, and the buckling portion includes a long rib extending in the first direction, and the two ends of the long rib are respectively connected to the frame body, and the long rib has an arched portion for buckling. On the one hand, the buckling portion on the elastic sheet has the characteristic of elastically contracting under pressure, which is conducive to the ability to recover in the slot of the second circuit board and buckle and fix with the buckle groove in the slot. On the other hand, the shape of the arched portion on the long rib is conducive to two-way operation, which can enable the buckling portion to buckle with the buckle groove smoothly when the two boards are connected, and can also allow the buckling portion to detach from the buckle groove to release the buckle when the two boards are separated.

[0018] An improvement is made to the electrical connection structure, wherein the connector is provided with more than two groups of the pins, and a buckle block is located between two adjacent groups of the pins; the second circuit board is provided with a plurality of the conductive components having the same number as the pin groups, and a buckle hole for buckling with the buckle block is provided between two adjacent conductive components. In this way, in order to solve the problem of unstable connection due to lack of connection structure in the middle of the connector after "capacity increase", a buckle block is provided between two adjacent groups of the pins in the connector of this embodiment, so as to buckle with the buckle hole added on the second circuit board after "capacity increase", thereby improving the connection stability between the two boards and effectively ensuring the electrical connection stability between each pin and each conductive component.

[0019] In one embodiment, the connector is provided with a marking hole, which penetrates between two adjacent groups of the pin headers and is arranged to avoid the buckle block. In this way, the marking hole is used to remind the operator that the position corresponds to the interval between the two groups of pin headers, so as to serve as a positioning mark during installation, thereby improving the accuracy of the installation operation.

[0020] Another improvement is made to the electrical connection structure. The connector is provided with more than two groups of the pins, and the installation slots are located on both sides of each group of the pins, and the elastic sheet is installed on each of the installation slots, and there is also a through slot connected to the installation slot between two adjacent groups of the pins; the second circuit board is provided with a plurality of the conductive parts with the same number as the groups of the pins, and a plurality of the slots with the same number as the elastic sheets and the buckle slots located in each of the slots; wherein, there is an outwardly extending plug-in portion between adjacent conductive parts, and the plug-in portion is used to insert into the through slot on the connector. In this way, in order to solve the problem that the middle part of the connector after "capacity increase" lacks a connection structure and is prone to unstable connection, on the connector of this embodiment, a through slot is set between the two groups of pins, so that elastic sheets can be installed on both sides of each group of pins on the connector, so as to connect with the connection end of the second circuit board after "capacity increase", effectively improving the connection stability between the two boards, and improving the operability of plug-in connection between the two boards.

[0021] In one embodiment, the connector is further provided with a second chamfer located on the notch of the through slot, so that the notch of the through slot is guided and expanded, which is beneficial for the installation and alignment operation, so that the plug-in part on the second circuit board can slide into the through slot along the expansion of the through slot and be smoothly plugged into place, effectively eliminating the impact of the installation operation caused by the dimensional tolerance, thereby improving the smoothness of the connection operation of the two boards and improving the assembly efficiency.

[0022] In the second aspect, the embodiment of the present application also provides an electronic atomization device, including an atomizer, a power supply component, and an electrical connection structure between the circuit boards, the power supply component including a battery, the battery abuts against the atomizer and is connected to the second circuit board; a control panel is provided on the first circuit board, the first circuit board is vertically connected to one side of the second circuit board through the connector, and the side of the first circuit board facing away from the control panel abuts against the battery. In this way, the various components in the electronic atomization device are compactly arranged, which is conducive to reducing the occupied space and reducing the overall volume.

[0052] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0053] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0054] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0055] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0056] The traditional electrical connection between circuit boards generally adopts a pin header connection structure, which connects the electrical connection parts of two circuit boards together by welding. However, since the spacing between the pin headers is relatively close, especially on small circuit boards, the spacing between the pin headers is even smaller, which leads to the undesirable phenomenon of solder joints during welding.

[0057] In the related art, there is a method of directly connecting two circuit boards by welding wires. However, when there are many wire harnesses, the circuit board occupies a large area, and the space utilization rate on the board is low. At the same time, the welding workload is also increased, the cost is high, the defect rate is also high, and it is not convenient for repair and rework.

[0058] In addition, there is another method of connection using FPC flexible cables. This connection method requires connectors to be installed on each circuit board, which increases costs and makes automated production difficult to achieve.

[0059] Therefore, the applicant has painstakingly studied and designed a new type of electrical connection structure between boards, breaking the inherent thinking of industry professionals (the inherent thinking is that the traditional electrical connection structure between boards can only be achieved by welding pin headers or wire harnesses, or by using FPC soft cables instead of pin headers to achieve mutual connection), and creatively proposed a new type of electrical connection structure between circuit boards and an electronic atomization device using the electrical connection structure, and improved the electrical connection structure between circuit boards. When implementing the connection between boards, a plug-in connection can be made through a connector, and the connection and fixation of the two boards can be achieved by using the snap-on structure on the connector. Quick connection or separation can be achieved without auxiliary tools and welding processing, effectively improving production efficiency and reducing production and maintenance costs, and solving the technical problem that the traditional electrical connection structure between circuit boards is prone to bridging when welding, resulting in poor connection. It is now described in detail.

[0060] Please also read Figure 1 , Figure 2 and Figure 3 The electrical connection structure 100 of the present application is provided on the first circuit board 1 and the second circuit board 2 , and the electrical connection structure 100 at least includes a connector 3 and an elastic sheet 4 arranged on the connector 3 .

[0061] It should be noted that the first circuit board 1 and the second circuit board 2 are not specifically distinguished. For the purpose of explanation, as an example, the embodiment of the present application sets the connector 3 on the first circuit board 1. In other embodiments, the connector 3 can also be set on the second circuit board 2, and the features on the first circuit board 1 are changed accordingly.

[0062] Please also read Figure 3 , Figure 4 and Figure 5 The connector 3 can be preferably arranged on the first circuit board 1 in the form of a patch. The connector 3 is provided with a pin header 31 and mounting grooves 32 located on both sides of the connector 3, and the elastic sheet 4 is detachably arranged in the mounting groove 32. The shape of the mounting groove 32 is preferably matched with the elastic sheet 4, so that the elastic sheet 4 can slide into the mounting groove 32.

[0063] The elastic sheet 4 has a bent buckling portion 41, and the extended end 40 of the elastic sheet 4 extends from the mounting groove 32 of the connector 3 and is used to be mounted on the first circuit board 1. In this way, the elastic sheet 4 can be used as a positioning member of the connector 3, and the connector 3 is fixed on the first circuit board 1 by the elastic sheet 4.

[0064] Please also read Figure 2 , Figure 4 and Figure 6The second circuit board 2 has a conductive component 21 and slots 22 located on both sides of the conductive component 21. The conductive component 21 can preferably be a conductive contact, a "gold finger", etc. arranged on the second circuit board 2. The conductive component 21 is used to connect with the pin row 31 on the connector 3. The slots 22 on both sides of the conductive component 21 have buckle grooves 23 for buckling with the buckle parts 41 on the elastic sheet 4.

[0065] In this way, when the first circuit board 1 and the second circuit board 2 are connected to each other, the first circuit board 1 is connected to the conductive component 21 on the second circuit board 2 using the connector 3, and the elastic sheet 4 is simultaneously inserted into the slot 22, so that the buckling portion 41 on the elastic sheet 4 is buckled and fixed with the buckling groove 23.

[0066] Compared with the prior art, the electrical connection structure 100 between circuit boards provided in the embodiment of the present application is provided with a connector 3 on the connection end of one circuit board, and the connector 3 has a pin header 31 and an elastic sheet 4 for snap-on connection; and a conductive component 21 for connecting with the pin header 31 and slots 22 located on both sides of the conductive component 21 are provided on the connection end of the other circuit board. When the two circuit boards are connected, the connector 3 is used to realize plug-in installation connection, so that the pin header 31 and the conductive component 21 are plugged into each other, and at the same time, the elastic sheet 4 is plugged into the slot 22 on the side of the conductive component 21, so that the buckle part 41 on the elastic sheet 4 can be buckled with the buckle groove 23 in the slot 22, thereby replacing the welding method, so that the plug-in installation connection can be realized between the two circuit boards, thereby improving the installation efficiency and convenience.

[0067] It can be seen that the electrical connection structure 100 provided in the embodiment of the present application has a simple structure, and the connector 3 can be set on the circuit board through the patch process, which is conducive to reducing the cost of using the welding process, thereby reducing the difficulty of production and the welding defect rate. For the elastic sheet 4 on the connector 3, on the one hand, the elastic sheet 4 serves as a snap-fitting member connected to another circuit board, so that the circuit boards can be connected through plug-in connection, thereby achieving rapid assembly and improving production efficiency; it is convenient to disassemble during rework and maintenance, reducing scrap and saving costs. On the other hand, the elastic sheet 4 also serves as a positioning member to fix the connector 3 on the circuit board, so that the connector 3 is positioned on the end of the circuit board, which is convenient for being connected to another circuit board as an electrical connector. Since there is no need to use welding or set a screw fixing structure, it is particularly conducive to installing such a connector 3 on a small circuit board, effectively reducing the difficulty of processing and production costs.

[0068] For the fixing structure between the connector 3 and the first circuit board 1, in one embodiment of the present application, please refer to Figure 4 , Figure 5 and Figure 7A fixing hole 11 corresponding to the position of the elastic sheet 4 is opened on the first circuit board 1 , and the extending end 40 of the elastic sheet 4 extends out from the mounting groove 32 of the connector 3 and is plugged into the fixing hole 11 of the first circuit board 1 .

[0069] In this way, the elastic sheet 4 is fixed to the connector 3 through the mounting groove 32 on the connector 3, and at the same time, the extension end 40 thereof is extended and plugged into the fixing hole 11 of the first circuit board 1, thereby positioning the connector 3 on the first circuit board 1. The connection method between the elastic sheet 4 and the first circuit board 1 is made simpler and easier to implement. It can be seen that the elastic sheet 4 not only plays a snap-fit ​​role when the first circuit board 1 is connected to the second circuit board 2, but also plays a positioning role in connecting the connector 3 to the first circuit board 1. Especially on a small circuit board, after the connector 3 is fixed to the circuit board by a patch type, the elastic sheet is used as a positioning member to position the connector 3 at the end of the circuit board, which is conducive to assembly and connection with another circuit board, thereby reducing the difficulty of assembly and the production and maintenance costs.

[0070] For the structure on the connector 3, in one embodiment of the present application, please refer to Figure 4 , Figure 5 and Figure 8 The two sides of the connector 3 also have slots 33 extending from the mounting slot 32 to the outside, the elastic sheet 4 is accommodated in the mounting slot 32, and the buckle portion 41 on the elastic sheet 4 can extend into the slot 33.

[0071] Thus, when the first circuit board 1 is connected to the second circuit board 2, the elastic sheet 4 is inserted into the slot 22 of the second circuit board 2, and the buckling portion 41 on the elastic sheet 4 can be smoothly buckled with the buckling groove 23 in the slot 22. At the same time, the board surface M on both sides of the slot 22 of the second circuit board 2 can be plugged into the slot 33, and the board surface M of the second circuit board 2 is clamped and fixed by the slots 33 on both sides of the connector 3, which effectively improves the connection stability between the first circuit board 1 and the second circuit board 2.

[0072] Preferably, the slots 33 on both sides of the connector 3 may be linear slots, so that the second circuit board 2 can be vertically connected to the first circuit board 1 .

[0073] Based on the above, in one embodiment of the present application, please refer to Figure 4 The connector 3 is also provided with a first chamfer 331 located on the notch of the slot 33. It can be understood that the first chamfer 331 is provided on the insertion port of the slot 33 for inserting the board surface M of the second circuit board 2, so that the notch for insertion on the slot 33 is guided and expanded. This is conducive to installation alignment, so that the board surface M of the second circuit board 2 located on the side of the slot 22 can slide smoothly into the slot 33 along the expansion of the slot 33, thereby improving the assembly efficiency between the two circuit boards.

[0074] For the structure of the elastic sheet 4, in one embodiment of the present application, please refer to Fig. 9 and Fig.10 The elastic sheet 4 includes a frame 42 and a buckle portion 41 on the frame 42. In this embodiment, the frame 42 is preferably a rectangular frame, which is convenient for orientation operation. One side of the frame 42 has an extension end 40 extending outward.

[0075] A through hole 34 communicating with the mounting groove 32 is provided on the side of the connector 3 facing away from the pin header 31 . The extending end 40 of the elastic sheet 4 extends out of the through hole 34 and is used to be fixed on the first circuit board 1 .

[0076] In this way, the elastic sheet 4 is detachably arranged on the connector 3, and the snap-on portion 41 on the elastic sheet 4 is used to snap and fix on the second circuit board 2. At the same time, the elastic sheet 4 also serves as a positioning member for the connector 3 and the first circuit board 1. The extended end 40 of the elastic sheet 4 is plugged and fixed on the first circuit board 1, so that the connector 3 is positioned on the end of the first circuit board 1, which is convenient for connection with the second circuit board 2.

[0077] In this embodiment, please refer to Fig. 9 , Fig.10 and Fig.11 The connector 3 is also provided with a limit portion 321 located in the mounting groove 32, and the limit portion 321 is used to limit the insertion stroke of the frame 42. The width of the extension end 40 of the elastic sheet 4 is smaller than the width of the frame 42, so that the elastic sheet 4 is inserted into the mounting groove 32 of the connector 3 until the frame 42 of the elastic sheet 4 stops against the limit portion 321. At this time, the extension end 40 of the elastic sheet 4 can extend from the through hole 34 of the connector 3 to be fixed on the second circuit board 2.

[0078] In this way, the elastic sheet 4 is installed and positioned on the connector 3 . After the elastic sheet 4 is installed in place in the installation groove 32 , only the extended end 40 of the elastic sheet 4 extends out from the through hole 34 at the back of the connector 3 to connect with the first circuit board 1 .

[0079] In addition, after the elastic sheet 4 is installed in place, the buckle portion 41 on the elastic sheet 4 can be matched with the buckle groove 23 in the slot 22 on the second circuit board 2, which is conducive to ensuring the position matching accuracy of the snap connection.

[0080] In order to ensure that the buckle portion 41 on the elastic sheet 4 has a deformation effect, the structure on the elastic sheet 4 is further improved. In one embodiment of the present application, please refer to Fig.11The buckle connection part 41 of the elastic sheet 4 is arranged in the frame opening 43 of the frame body 42, and the buckle connection part 41 includes a long rib 411 extending in the first direction F, where the "first direction F" can be understood as the direction in which the elastic sheet 4 is inserted into the slot 22. The two ends of the long rib 411 are respectively connected to the frame body 42, and the frame opening 43 has a movable gap 431 located on both sides of the long rib 411 for the long rib 411 to move, and the middle part of the long rib 411 has an arched part 412 for buckling.

[0081] In this way, the buckle portion 41 on the elastic sheet 4 has the characteristic of elastically contracting under pressure, which is conducive to restoring in the slot 22 of the second circuit board 2 and buckling and fixing with the buckle groove 23 in the slot 22 when the two boards are connected. The shape of the arched portion 412 on the long rib 411 is conducive to two-way operation, which can not only enable the buckle portion 41 to buckle with the buckle groove 23 smoothly when the two boards are connected, but also enable the buckle portion 41 to detach from the buckle groove 23 to release the buckle when the two boards are separated.

[0082] In practical applications, in order to increase the specifications of the pin header 31, the number of the pin headers 31 is generally increased, resulting in changes in the electrical connection structure 100 between the two boards. The inventors found that when the number of the pin headers 31 increases, the width of the connector 3 needs to be increased, resulting in a decrease in the connection stability of the middle area of ​​the connector 3, affecting the electrical contact stability between the pin header 31 and the conductive component 21. Therefore, it is necessary to improve the connector 3 after "capacitance increase" and the connection terminal structure on the second circuit board 2.

[0083] In one embodiment of the present application, please refer to Fig.12 and Fig.13 The connector 3 is provided with more than two groups of pin headers 31 , and a buckle block 35 located between two adjacent groups of pin headers 31 .

[0084] The second circuit board 2 is provided with a plurality of conductive components 21 having the same number as the number of the pin headers 31 , and a buckle hole 24 for buckling with the buckle block 35 is provided between two adjacent conductive components 21 .

[0085] In this embodiment, the connector 3 has two groups of pin headers 31, and a protruding buckle block 35 is provided on the spacing area between the two groups of pin headers 31; correspondingly, the second circuit board 2 is provided with two conductive components 21, and the positions of the two conductive components 21 correspond one-to-one to the two groups of pin headers 31 on the connector 3, and a buckle hole 24 is opened at the connecting portion between the two conductive components 21.

[0086] In this way, in order to solve the problem of unstable connection due to lack of connection structure in the middle of the “increased” connector 3, a buckle block 35 is provided between two adjacent groups of pin headers 31 on the connector 3 of the present embodiment, so as to buckle with the buckle holes 24 added on the “increased” second circuit board 2, thereby improving the connection stability between the two boards and effectively ensuring the electrical connection stability between each pin header 31 and each conductive component 21.

[0087] Preferably, in this embodiment, please refer to Fig.14 The connector 3 is provided with an identification hole 36 , which penetrates between two adjacent groups of pin headers 31 , and the identification hole 36 is arranged to avoid the buckle block 35 .

[0088] On the one hand, the identification hole 36 is used to remind the operator that this position corresponds to the interval between the two groups of pin headers 31, so as to serve as an alignment mark when connecting the two boards, thereby improving the accuracy of the installation operation.

[0089] On the other hand, the identification hole 36 can also be used as a processing hole for adding the buckle block 35 in the connector 3, so that the buckle block 35 on the connector 3 can be easily processed and formed.

[0090] Another improvement is made to the connector 3 and the connection end structure on the second circuit board 2 after the "capacity increase". In another embodiment of the present application, please refer to Fig.15 and Fig.16 The connector 3 is provided with more than two groups of pin headers 31 and mounting grooves 32 located on both sides of each group of pin headers 31. An elastic sheet 4 is installed on each mounting groove 32. There is also a through groove 37 between two adjacent groups of pin headers 31, and the through groove 37 is connected to the two adjacent mounting grooves 32 respectively.

[0091] The second circuit board 2 is provided with a plurality of conductive components 21 having the same number as the groups of the pin headers 31, and a plurality of slots 22 having the same number as the elastic sheet 4 and buckle slots 23 located in each slot 22. Among them, an outwardly extending plug-in portion 25 is provided between adjacent conductive components 21, and the plug-in portion 25 is used to be inserted into the through slot 37 on the connector 3.

[0092] In this embodiment, two groups of pin headers 31 are provided in one connector 3. The two groups of pin headers 31 are provided in two separated spaces on the connector 3. Both sides of each group of pin headers 31 are provided with mounting grooves 32 for mounting elastic sheets 4. The space between the two groups of pin headers 31 is provided with a through groove 37 connected to two adjacent mounting grooves 32, so that the buckle 41 on the elastic sheet 4 provided in the two mounting grooves 32 can extend into the through groove 37. Fig.17 and Fig.18As shown, the extension ends 40 of the elastic sheets 4 on both sides of each group of pin headers 31 can extend from the back of the connector 3 and be used to be plugged into the fixing holes 11 of the first circuit board 1 to position the connector 3 .

[0093] In conjunction with Fig.15 As shown, two conductive components 21 are provided on the second circuit board 2, and the positions of the two conductive components 21 correspond to the two groups of pin headers 31 on the connector 3. A plug-in portion 25 is provided between the two conductive components 21, and the plug-in portion 25 is used to be plugged in with the through slot 37 on the connector 3. Both sides of the plug-in portion 25 are provided with slots 22 located at the sides of the two conductive components 21, and buckle slots 23 located in the slots 22, so that the elastic sheets 4 at the corresponding positions on the connector 3 can be plugged in with the slots 22 respectively, and at the same time, the buckle portion 41 on the elastic sheet 4 is buckled with the buckle slot 23, so as to ensure the connection and fixing effect.

[0094] The connection structure in this embodiment is conducive to the use of connectors 3 with larger "capacity increase" specifications (i.e., connectors 3 that need to add a large number of pin headers 31). In order to solve the problem of unstable connection due to the lack of connection structure in the middle of the "capacity increase" connector 3, a through groove 37 is set between the two groups of pin headers 31 on the connector 3 of this embodiment, so that elastic sheets 4 can be installed on both sides of each group of pin headers 31 on the connector 3, so as to connect with the connection end of the second circuit board 2 after the "capacity increase", effectively improving the connection stability between the two boards and improving the plug-in connection operability between the two boards.

[0095] In practical applications, dimensional tolerances are unavoidable in production, especially in the small connector 3 in the embodiment of the present application. The negative impact of such dimensional tolerances is easily magnified, resulting in difficulty in accurately aligning the connector 3 with the second circuit board 2 after a through groove 37 is added to the middle of the connector 3; or, due to tolerances after alignment, the plug-in portion 25 cannot be smoothly inserted into the through groove 37, resulting in the inability to connect the two boards.

[0096] Here, for the above situation, in this embodiment, please refer to Fig.16 The connector 3 is preferably provided with a second chamfer 371 on the notch of the through slot 37, so that the notch of the through slot 37 is expanded and guided. This is beneficial for the installation and alignment operation, so that the plug-in portion 25 on the second circuit board 2 can slide into the through slot 37 along the expansion of the through slot 37 and be smoothly inserted into place, effectively eliminating the installation operation influence caused by the dimensional tolerance, thereby improving the smoothness of the connection operation of the two boards and improving the assembly efficiency.

[0097] In another embodiment of the present application, please refer to Fig.19 and Fig. 20The embodiment of the present application also provides an electronic atomization device, which includes an atomizer 5, a power supply component and an electrical connection structure 100 between the circuit boards provided in the embodiment of the present application.

[0098] The atomizer 5 may include a liquid storage tank and an atomization core located in the liquid storage tank, so that it can realize the function of atomizing the aerosol matrix in the liquid storage tank.

[0099] In this embodiment, the first circuit board 1 can preferably be used as the main control board of the electronic atomization device. A control panel 12 is provided on the first circuit board 1. The control panel 12 is exposed on the body of the electronic atomization device for human operation to control the electronic atomization device.

[0100] The second circuit board 2 can preferably be used as a sub-control board on the electronic atomization device for controlling the function of the atomizer 5. The second circuit board 2 is preferably arranged horizontally on the electronic atomization device.

[0101] The power supply assembly includes a battery 6, which is adjacent to the atomizer 5 and connected to the second circuit board 2. The first circuit board 1 is vertically connected to one side of the second circuit board 2 through the connector 3, and the side of the first circuit board 1 facing away from the control panel 12 is against the battery 6.

[0102] In this way, the various components in the electronic atomization device can be arranged compactly, which is beneficial to reducing the occupied space and the overall volume.

[0103] It should be noted that the electrical connection structure 100 between circuit boards provided in the embodiment of the present application can also be used in other electrical equipment to achieve electrical connection between two circuit boards. In particular, between two small circuit boards inside a small electrical equipment, the electrical connection structure 100 provided in the embodiment of the present application can be used to achieve electrical connection between the two boards, thereby solving the defects of the traditional pin header 31 welding or the FPC soft row replacement method, effectively improving production efficiency and reducing production and maintenance costs.

[0104] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
