[0002] In the existing electronic devices, the fixing and charging PIN functions of the PCBA (Printed Circuit Board Assembly) are designed as two independent parts. That is, for the charging PIN function, after the charging PIN is welded to the elastic piece for conduction, the elastic piece contacts the PCBA to achieve conduction / charging; while the PCBA is fixed by separately provided screws and nuts.
[0003] The existing structure with the charging and fixing functions designed separately has the following disadvantages: one is that the number of components is large, resulting in the production cost not being able to be further reduced; the other is that it makes the internal space of the product complex, which is not conducive to saving the internal space and the development of the product towards thin and light.
[0004] Therefore, it is necessary to provide a conductive connection component with both charging PIN function and fixing function, and an electronic device with the conductive connection component to solve the above problems. Summary of the Utility Model

[0010] Preferably, the conductive connection assembly further includes a conductive gasket, one end of the conductive gasket is electrically connected to the circuit board, and the other end of the conductive gasket is electrically connected to the first pressing portion or the second pressing portion.
[0011] Preferably, the conductive gasket includes a first fixing portion and a second fixing portion in a bent shape. One of the first fixing portion and the second fixing portion is welded to the circuit board to achieve electrical connection, and the other of the first fixing portion and the second fixing portion is electrically connected to the first pressing portion or the second pressing portion.
[0012] Preferably, a rib is provided between the first pressing portion and the housing or between the second pressing portion and the housing. The first pressing portion or the second pressing portion squeezes the rib to achieve sealing. The method of achieving sealing by setting the rib is applicable to the case where the waterproof level is relatively low, but the waterproof rubber ring can be omitted, thereby saving the cost of the waterproof rubber ring.
[0013] Preferably, the conductive connection assembly further includes a waterproof ring. The waterproof ring is sleeved on the first locking portion or the second locking portion. The waterproof ring is squeezed between the first pressing portion and the housing or between the second pressing portion and the housing to achieve sealing. Setting the waterproof ring can achieve a better sealing effect, so it is applicable to the case where the waterproof level is relatively high.
[0014] Correspondingly, the present invention further provides an electronic device, which includes a housing, a circuit board installed in the housing, and the conductive connection assembly as described above, and the circuit board is fixed and the charging PIN function is realized through the conductive connection assembly.
[0015] Preferably, a first abutting portion is provided on the housing; the conductive member further includes a first pressing portion provided at one end of the first locking portion, and the connecting member further includes a second pressing portion provided at one end of the second locking portion; the first pressing portion or the second pressing portion abuts against the first abutting portion, and a rib is provided between the first pressing portion and the first abutting portion or between the second pressing portion and the first abutting portion.

Therefore, when fixing the circuit board, the conductive member or the connecting member is passed through the housing and the circuit board, and is fixed by locking and connecting the first locking portion and the second locking portion, and at the same time, the conductive member is directly electrically connected to the circuit board or the conductive member is electrically connected to the circuit board through the connecting member, thereby enabling the conductive member to realize the charging PIN function. Through the setting of the conductive member in this application, the conductive member and the connecting member cooperate to not only realize the fixation of the circuit board but also realize the charging PIN function of the conductive member. Compared with the prior art in which the charging PIN realizes conduction through elastic sheet welding and the fixation is realized through screwing of screws and nuts, this application combines the charging PIN and nut functions into one, thereby omitting the screws, saving the assembly cost; at the same time, it saves the space in the housing for installing screw posts, and this part of the space can be used for other layouts, thus saving the internal space and being beneficial to the development of the product towards thinness and lightness.

[0029] Now, embodiments of the present utility model will be described with reference to the accompanying drawings, where like reference numerals represent like elements. It should be noted that the orientation descriptions involved in the present utility model, such as up, down, left, right, front, back, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the technical solutions of the present application and / or simplifying the description, rather than indicating or implying 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 construed as a limitation to the present application. The first, second, etc. described are only used to distinguish technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.
[0030] Combined with Figures 1-9 As shown, the conductive connection component 100 provided by the present utility model is mainly used to fix the circuit board 200 to the housing 300 and simultaneously implement the function of the charging PIN. Among them, the circuit board 200 may be a PCB (Printed circuit board) board, or a PCBA (Printed Circuit Board Assembly) board, etc., or other components that need to achieve conductive connection, and no specific limitation is made thereto in the present utility model.
[0031] Continue to combine with Figures 1-9As shown, the present utility model further provides an electronic device 1, which includes a conductive connection component 100, a circuit board 200, and a housing 300. Among them, the circuit board 200 is installed on the housing 300. As for the specific shape of the housing 300, it is not limited and is correspondingly set according to different electronic devices 1 and different parts of the electronic device 1. The conductive connection component 100 fixes the circuit board 200 on the housing 300. At the same time, the conductive connection component 100 constitutes the charging PIN of the circuit board 200. That is to say, the conductive connection component 100 realizes the fixation of the circuit board 200 and the function of the charging PIN at the same time. The structure of the conductive connection component 100 will be described in detail below with reference to the accompanying drawings.
[0032] Combined with Figures 2-9 As shown, in the present utility model, the conductive connection component 100 includes a conductive member 110 and a connecting member 120. Among them, the conductive member 110 includes a first locking portion 111. The connecting member 120 includes a second locking portion 121 that can be locked and matched with the first locking portion 111. When the circuit board 200 is installed on the housing 300, the conductive member 110 or / and the connecting member 120 penetrate through the housing 300 and the circuit board 200, and are fixedly connected by locking the first locking portion 111 and the second locking portion 121, so as to fix the housing 300 and the circuit board 200. At the same time, the conductive member 110 is directly in contact with the circuit board 200 to achieve electrical connection, or the connecting member 120 is electrically connected to the circuit board 200, and the conductive member 110 is electrically connected to the circuit board 200 through the connecting member 120. In this application, the first locking portion 111 is provided on the conductive member 110, so that the conductive member 110 can be locked and matched with the connecting member 120. That is, the conductive member 110 realizes the functions of fixation and conduction at the same time. Compared with the prior art in which the charging PIN is electrically connected to the circuit board through a spring piece and fixed by screwing a screw and a nut, the structure of this application omits the screw post, thereby reducing the number of fixing parts and saving the assembly cost.
[0033] Continue to combine Figures 2-9As shown, in the present utility model, the conductive member 110 further includes a first pressing portion 112, and the first locking portion 111 protrudes from the first pressing portion 112. Correspondingly, the connecting member 120 further includes a second pressing portion 122, and the second locking portion 121 protrudes from the first pressing portion 112. In this way, the first locking portion 111 or the second locking portion 121 passes through the housing 300 and the circuit board 200. When the first locking portion 111 and the second locking portion 121 are locked and connected, the first pressing portion 112 and the second pressing portion 122 respectively press against the housing 300 and the circuit board 200. More specifically, if the first pressing portion 112 presses against the circuit board 200, the conductive member 110 directly contacts the circuit board 200 to achieve electrical connection; if the second pressing portion 122 presses against the circuit board 200, the connecting member 120 directly contacts the circuit board 200 and is electrically connected, and the conductive member 110 achieves electrical connection with the circuit board 200 through the connecting member 120.
[0034] Combined with Figure 2 、 Figure 6 As shown, in the present utility model, a first connection hole 310 is formed on the housing 300, and a second connection hole 210 is formed on the circuit board 200. Combined with Figure 5 、 Figure 9 As shown, after the circuit board 200 is assembled on the housing 300, the second connection hole 210 thereon is opposite to the first connection hole 310. The first locking portion 111 or the second locking portion 121 sequentially passes through the first connection hole 310 and the second connection hole 210, and then the first locking portion 111 and the second locking portion 121 are locked, so that the first pressing portion 112 and the second pressing portion 122 respectively press against the housing 300 and the circuit board 200.
[0035] Combined with Figure 5 、 Figure 9 As shown, in a specific embodiment, the first locking portion 111 of the conductive member 110 sequentially passes through the housing 300 and the circuit board 200, so that the first pressing portion 112 presses against the housing 300. The second locking portion 121 of the connecting member 120 passes through the circuit board 200 and is then locked and connected to the first locking portion 111, and the second pressing portion 122 presses against the circuit board 200 and is electrically connected to the circuit board 200. Therefore, conduction is achieved between the first locking portion 111 and the second locking portion 121 through locking connection, that is Figure 5 、 Figure 9 the conduction position A shown in
[0036] More preferably, the end of the first locking portion 111 can also contact the circuit board 200 to achieve conduction, that is, the end of the first locking portion 111 presses against the circuit board 200 and is electrically connected to the circuit board 200, as Figure 5 , Figure 9 The conduction position B shown. At this time, conduction is achieved between the conductive member 110 and the circuit board 200 when passing through the two conduction positions A and B, thereby strengthening the electrical connection effect between the conductive member 110 and the circuit board 200, and strengthening the conductive stability between the charging PIN and the circuit board 200.
[0037] Continuing to combine Figures 4-5 , Figures 8-9 shown, in an embodiment of the present invention, the conductive member 110 and the connecting member 120 are threadedly connected to achieve locking. Specifically, one of the first locking portion 111 and the second locking portion 121 is provided with a threaded hole, and the other of the first locking portion 111 and the second locking portion 121 is provided with an external thread. The first locking portion 111 and the second locking portion 121 are locked by threaded connection, which not only facilitates the processing of the conductive member 110 and the connecting member 120, but also facilitates the locking connection between the two.
[0038] In a specific embodiment, a threaded hole is provided in the first locking portion 111, and an external thread is provided on the outside of the second locking portion 121. The second locking portion 121 can be tightened into the threaded hole on the first locking portion 111 to achieve fixation. Therefore, conduction is achieved between the first locking portion 111 and the second locking portion 121 through threaded engagement, that is, conduction is achieved between the conductive member 110 and the connecting member 120 through threaded engagement.
[0039] It is understandable that the connection between the conductive member 110 and the connecting member 120 is not limited to threaded connection. For example, in other embodiments, the conductive member 110 and the connecting member 120 can also be directly fastened and matched or locked in other ways.
[0040] Continuing to combine Figures 4-5 , Figures 8-9 shown, in an embodiment of the present invention, the conductive connection assembly 100 further includes a conductive gasket 130. One end of the conductive gasket 130 is electrically connected to the circuit board 200, and the other end of the conductive gasket 130 is electrically connected to the first pressing portion 112 or the second pressing portion 122.
[0041] In a specific embodiment, the conductive gasket 130 includes a bent first fixing portion 131 and a second fixing portion 132. One of the first fixing portion 131 and the second fixing portion 132 is welded to the circuit board 200 to achieve electrical connection, and the other of the first fixing portion 131 and the second fixing portion 132 abuts against the first pressing portion 112 or the second pressing portion 122. The electrical connection and conduction are achieved through the conductive gasket 130, which can make the installation between the circuit board 200 and the housing 300 more flexible.
[0042] In this specific embodiment, the second fixing portion 132 has a plate-like structure, and a through hole is formed in the second fixing portion 132. A vertical connecting portion 133 protrudes from the edge of the second fixing portion 132. The upper end of the vertical connecting portion 133 is connected to the bent first fixing portion 131. That is to say, the first fixing portion 131 protrudes outward relative to the outer edge of the second fixing portion 132, so that the first fixing portion 131 and the second fixing portion 132 are in a stepped shape. When connecting, the second fixing portion 132 is arranged below the second connecting hole 210 of the connecting member 120, and the first fixing portion 131 is welded to the circuit board 200 to achieve electrical connection. At this time, the through hole on the second fixing portion 132 is communicated with the second connecting hole 210, as Figure 5 、 Figure 9 shown. Then, the second locking portion 121 of the connecting member 120 passes through the through hole on the second fixing portion 132 and is locked to the first locking portion 111. At this time, the second locking portion 121 presses against the second fixing portion 132 to achieve electrical connection with the circuit board 200. Therefore, the conductive member 110 is conducted to the circuit board 200 through the connecting member 120 and the conductive gasket 130.
[0043] Continuing to combine Figures 4-5 、 Figures 8-9 shown, in this specific embodiment, the outer diameter of the through hole on the second fixing portion 132 is smaller than the outer diameter of the first locking portion 111. In this way, the first locking portion 111 of the conductive member 110 sequentially passes through the first connecting hole 310 on the housing 300 and the second connecting hole 210 on the circuit board 200, and then the end portion of the first locking portion 111 abuts against the second fixing portion 132. At this time, the first locking portion 111 contacts the conductive gasket 130 to form a conduction position B, as Figure 5 、 Figure 9 shown. That is, the conductive member 110 is conducted to the circuit board 200 through the conductive gasket 130. At the same time, a conduction position A is formed between the first locking portion 111 and the second locking portion 121 by screw engagement. That is, the conductive member 110 is conducted to the circuit board 200 through the connecting member 120 and the conductive gasket 130. The two conduction positions A and B enhance the conductive stability between the conductive member 110 and the circuit board 200.
[0044] Next, combining with Figures 2-3 、Figure 5 As shown, in an embodiment of the present utility model, ribs are provided between the first pressing portion 112 and the housing 300 or between the second pressing portion 122 and the housing 300. The first pressing portion 112 or the second pressing portion 122 presses the ribs to achieve sealing, thereby realizing the waterproof function of the conductive member 110.
[0045] In a specific embodiment, the ribs 320 are integrally formed on the housing 300 and are arranged around the first connection hole 310. Specifically, a first abutting portion 311 is provided in the first connection hole 310, and the ribs 320 protrude from the first abutting portion 311, as Figure 5 shown. When the conductive member 110 is installed, its first locking portion 111 passes through the first connection hole 310, so that the first pressing portion 112 abuts against the first abutting portion 311. After the conductive member 110 is locked, the ribs 320 are pressed between the first pressing portion 112 and the first abutting portion 311 to form a sealing ring. The method of realizing sealing by setting the ribs 320 is applicable to the case where the waterproof level is relatively low. For example, when the waterproof level is between IPX2 - IPX5, this structural setting can be adopted, and this method can save the cost of the waterproof rubber ring.
[0046] As shown below in conjunction with Figures 6-9 In another embodiment of the present utility model, the conductive connection assembly 100 further includes a waterproof ring 140. The waterproof ring 140 is sleeved on the first locking portion 111 or the second locking portion 121, and after the first locking portion 111 or the second locking portion 121 is locked, the waterproof ring 140 is pressed between the first pressing portion 112 and the housing 300 or between the second pressing portion 122 and the housing 300 to achieve sealing. Setting the waterproof ring 140 can achieve a better waterproof effect, so it is applicable to products with higher waterproof level requirements. For example, when the waterproof level is between IPX6 - 5ATM, the structure of the waterproof ring 140 can be adopted.
[0047] In a specific embodiment, a second abutting portion 312 is further provided in the first connection hole 310 of the housing 300, and the second abutting portion 312 and the first abutting portion 311 are in a stepped shape, as Figure 9 shown. The waterproof ring 140 is sleeved outside the first locking portion 111 of the conductive member 110. After the first locking portion 111 of the conductive member 110 passes through the first connection hole 310, the waterproof ring 140 abuts against the second abutting portion 312. After the first locking portion 111 and the second locking portion 121 are locked, the first pressing portion 112 of the conductive member 110 abuts against the first abutting portion 311. At the same time, the first pressing portion 112 presses the waterproof ring 140, thereby pressing the waterproof ring 140 between the first pressing portion 112 and the second abutting portion 312, as Figure 9as shown, so as to achieve a good sealing effect.
[0048] Understandably, in this embodiment, a rib can be further provided between the first pressing portion 112 and the first abutting portion 311. Through the double sealing of the rib and the waterproof ring 140, a higher level of waterproof effect can be achieved.
[0049] Combined Figure 2 、 Figures 5-6 、 Figure 9 As shown, the conductive connection assembly 100 further includes a gasket 150. The gasket 150 is disposed between the conductive gasket 130 and the conductive member 110. The gasket 150 is a conventional structure in the art and will not be described in detail.
[0050] In summary, due to the conductive connection assembly 100 of the present utility model, a first locking portion 111 is provided on the conductive member 110, and the second locking portion 121 of the connecting member 120 is set to be a structure capable of locking and cooperating with the first locking portion 111. Therefore, when fixing the circuit board 200, the conductive member 110 or the connecting member 120 is passed through the housing 300 and the circuit board 200, and is fixedly connected by locking the first locking portion 111 and the second locking portion 121. At the same time, the conductive member 110 is directly electrically connected to the circuit board 200 or the conductive member 110 is electrically connected to the circuit board 200 through the connecting member 120, thereby enabling the conductive member 110 to achieve the charging PIN function. Through the setting of the conductive member 110 in this application, the conductive member 110 and the connecting member 120 cooperate to not only fix the circuit board 200, but also achieve the charging PIN function of the conductive member 110. Compared with the prior art in which the charging PIN realizes conduction through elastic sheet welding and fixation is achieved through screwing of screws and nuts, this application combines the charging PIN and nut functions into one, thereby omitting the screws, thus saving assembly costs; at the same time, the space for installing screw posts in the housing 300 is saved, and this part of the space can be used for other layouts, thereby saving internal space and being beneficial to the development of the product towards thinness and lightness.
[0051] Correspondingly, the electronic device 1 having the conductive connection assembly 100 also has the above technical effects.
[0052] The above-disclosed are only the preferred embodiments of the present utility model, and of course, the scope of rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present utility model still fall within the scope covered by the present utility model.
