[0079] The "parallel" / "vertical" and similar expressions used in the present invention include an absolute parallel / vertical relationship and a roughly parallel / vertical relationship (for example, a relationship that differs from absolute parallel / vertical by -5° to +5°), which can have the same effect.

[0080] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present invention and are not intended to limit the present invention.

[0081] like Figures 1 to 9 As shown, the board-end connector according to the utility model may include a connector body 110 and an adapter connector 120. The adapter connector 120 may include a plate body 121 and a tube body 122. The tube body 122 is connected to the plate body 121. The plate body 121 may include a mounting hole 121c that is arranged along the first direction D1. The tube body 122 extends along the first direction D1 and protrudes from the plate body 121. The plate body 121 has a first connection portion. The first connection portion is suitable for connecting to the mounting panel 130 of the electronic device 100 when the adapter connector 120 is installed to the electronic device 100. The tube body 122 has a second connection portion. The second connection portion is suitable for connecting to the connector body 110. In the installed state, the position of the adapter connector 120 in the first direction D1 can be limited by the cooperation of the plate body 121 and the mounting panel 130, and the assembly gap between the connector body 110 and the mounting panel 130 is shielded by the plate body 121. The tube body 122 is suitable for passing through the through hole 130a of the mounting panel 130. The tube body 122 is sleeved on the outside of the connector body 110 to at least partially fill the gap between the connector body 110 and the through hole 130a. In a plane perpendicular to the first direction D1, the outer periphery of the orthographic projection of the plate body 121 is located outside the tube body 122.

[0082] According to the board-end connector of the utility model, by providing the adapter connector 120, when installed to the electronic device 100, the board body 121 connected to the mounting panel 130 is used to eliminate the assembly tolerance of the connector body 110 relative to the mounting panel 130 in the first direction D1, and the tube body 122 sleeved on the outside of the connector body 110 is used to absorb the assembly tolerance of the connector body 110 between the first direction D1 and the via 130a. By adopting the above technical means, the assembly tolerance between the connector body 110 and the mounting panel 130 when installed on the circuit board 140 can be effectively absorbed, thereby improving the sealing performance. Moreover, the utility model has a simple structure, is easy to manufacture and use, and is conducive to reducing costs.

[0083] See also Figures 1 to 7In addition, the board-end connector may further include a first sealing ring 112. The first sealing ring 112 is sleeved on the outside of the connector body 110. And the first sealing ring 112 is sealed between the outer circumference of the connector body 110 and the inner circumference of the tube body 122. By adding the first sealing ring 112 between the outer circumference of the connector body 110 and the inner circumference of the tube body 122 of the adapter connector 120, the sealing performance of the outer circumference of the connector body 110 and the inner circumference of the tube body 122 of the adapter connector 120 can be improved, thereby preventing foreign objects such as dust and water from the outside from passing through the gap between the outer circumference of the connector body 110 and the tube body 122.

[0084] See also Figure 1 , Figure 3 , Figure 5 as well as Figure 7 Further, at least one of the connector body 110 and the tube body 122 includes a first positioning groove 111a. A portion of the first sealing ring 112 is accommodated in the first positioning groove 111a. The remaining portion of the first sealing ring 112 protrudes from the first positioning groove 111a in a direction perpendicular to the first direction D1 to be pressed and fitted between the connector body 110 and the tube body 122. By providing the first positioning groove 111a to accommodate the first sealing ring 112, the first sealing ring 112 can be limited in the first direction D1.

[0085] exist Figure 1 , Figure 3 , Figure 5 as well as Figure 7 In the example shown, a first positioning groove 111a is provided on the outer circumference of the connector body 110. The first sealing ring 112 is sleeved on the outer circumference of the connector body 110 and is located in the first positioning groove 111a. During the installation process, the first sealing ring 112 is first assembled on the connector body 110, and then the connector body 110 with the first sealing ring 112 is inserted into the through hole 130a of the installation panel 130.

[0086] See also Figures 1 to 4 For example, the connector body 110 may include a connector body 111 and an assisting protrusion 111b. The connector body 111 has a first electrical terminal and a second electrical terminal spaced apart along a first direction D1. The first electrical terminal is plugged into the line end connector 160. The second electrical terminal is suitable for being connected to a circuit board 140 located inside the electronic device 100. The assisting protrusion 111b is protrudingly disposed on the outer surface of the connector body 111 along a direction intersecting the first direction D1. The assisting protrusion 111b is closer to the first electrical terminal than the second electrical terminal along the first direction D1. The assisting protrusion 111b is suitable for being inserted into the guide hole 161a of the assisting pull rod 161 of the line end connector 160 to assist in plugging the line end connector 160 into the first electrical terminal.

[0087] See also Figures 1 to 5 ,as well as Fig. 9 , wherein the wire end connector 160 includes a power-assisting rod 161. The power-assisting rod 161 can rotate to an initial position and an end position relative to the body of the wire end connector 160 around the rotation axis AX. The power-assisting rod 161 includes a hand-held portion and a working portion. The hand-held portion and the working portion are located on both sides of the rotation axis AX. The hand-held portion is suitable for being hand-operated by a user. The working portion includes a guide hole 161a. The guide hole 161a is arranged around the rotation axis AX. The guide hole 161a has a first end 161b and a second end 161c spaced apart in a circumferential direction. The distance between the first end 161b of the guide hole 161a and the rotation axis AX is greater than the distance between the second end 161c and the rotation axis AX. The first end 161b of the guide hole 161a is arranged to penetrate in a direction perpendicular to the rotation axis AX so as to be suitable for the power-assisting protrusion 111b to enter the guide hole 161a. In the process of inserting the wire end connector 160 into the connector body 110 with the assist rod 161 in the initial position, the first end 161b of the guide hole 161a is arranged corresponding to the assist protrusion 111b along the first direction D1. When the assist protrusion 111b just enters the first end 161b of the guide hole 161a, the wire end connector 160 and the connector body 110 have not yet been inserted into place. At this time, the assist rod 161 is rotated to the end position around the rotation axis AX by operating the handheld part, so that the second end 161c of the guide hole 161a gradually approaches the assist protrusion 111b. In this process, the distance between the assist protrusion 111b and the rotation axis AX gradually decreases. When the assist rod 161 rotates to the end position, the distance between the assist protrusion 111b and the rotation axis AX is the smallest, and at this time the wire end connector 160 and the connector body 110 are inserted into place. By providing the assist protrusion 111b to cooperate with the guide hole 161a of the assist rod 161, the convenience of the insertion operation of the line end connector 160 into the connector body 110 can be increased in application scenarios where the insertion resistance between the line end connector 160 and the connector body 110 is relatively large, thereby enabling corresponding operations to be performed more labor-savingly and improving the operator's operating experience.

[0088] See also Figure 1 and Figure 8In addition, the board-side connector may further include a dust cover 123. The dust cover 123 is openably connected to the adapter connector 120. The dust cover 123 has an open state and a closed state. The dust cover 123 in the open state can open the mounting hole 121c so that the line end connector 160 can be plugged into the connector body 110. The dust cover 123 in the closed state completely covers the mounting hole 121c to prevent foreign matter such as dust and water from entering the mounting hole 121c when the connector body 110 is not connected to the line end connector 160. In this way, the electrical terminals of the connector body 110 can be better protected and the service life of the connector body 110 can be extended. The function of the dust cover 123 is to prevent dust, water and other foreign objects from entering the mounting hole 121c during pre-sales and after-sales maintenance, disassembly, transportation and assembly by covering the mounting hole 121c of the adapter connector 120 with the dust cover 123, thereby preventing problems such as short circuit and burning caused by docking of the connector body 110 and the line end connector 160.

[0089] For example, the dust cover 123 may be detachably connected to the adapter connector 120 .

[0090] Another example Figure 1 and Figure 8 As shown, the dust cover 123 can also be pivotally connected to the adapter connector 120. The dust cover 123 here can be made into an integral part with the adapter connector 120, or can be connected to the adapter connector 120 through a transition connection structure such as a rope.

[0091] See also Figure 1 and Figure 8 Furthermore, the dust cover 123 may include a protruding structure 123a. The protruding structure 123a may block the mounting hole 121c of the adapter connector 120 when the dust cover 123 is in the covered state.

[0092] See also Figures 1 to 9The utility model also provides an electronic device 100. The electronic device 100 here may be a battery pack. The electronic device 100 may include a mounting panel 130, a circuit board 140 and the above-mentioned board-end connector. The mounting panel 130 may include a via 130a. In the application scenario where the electronic device 100 is a battery pack, the mounting panel 130 may be understood as a part of the battery pack, and the mounting panel 130 may be a part of the housing of the battery pack, or may be another component independent of the housing of the battery pack. The circuit board 140 is arranged corresponding to the via 130a along the first direction D1. The circuit board 140 is fixedly arranged relative to the mounting panel 130 along the first direction D1, the second direction D2 and the third direction D3. The first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other. The connector body 110 is penetrated by the via 130a. The tube body 122 of the adapter connector 120 is sleeved on the outside of the connector body 110. The plate body 121 of the adapter connector 120 is located on one side of the mounting panel 130 along the first direction D1 and is connected to the mounting panel 130. In the plane perpendicular to the first direction D1, the orthographic projection of the hole wall of the through hole 130a is located outside the orthographic projection of the outer peripheral surface of the tube body 122, and the orthographic projection of the plate body 121 completely covers the gap between the orthographic projection of the tube body 122 and the orthographic projection of the through hole 130a. That is, the aperture of the through hole 130a is larger than the outer diameter of the tube body 122. The radial outer dimension of the plate body 121 is larger than the aperture of the through hole 130a. In this way, it is ensured that the plate body 121 can absorb the assembly tolerance of the tube body 122 and the through hole 130a, and then the assembly tolerance of the connector body 110 and the mounting panel 130 at the through hole 130a is eliminated through the adapter connector 120.

[0093] According to the electronic device 100 of the present invention, by applying the above-mentioned board-end connector, the tolerance of the assembly of the connector body 110 on the mounting panel 130 can be effectively absorbed, thereby improving the sealing performance of the electronic device 100.

[0094] See also Figures 1 to 5 In addition, the electronic device 100 may further include a second sealing ring 125. The second sealing ring 125 is concentrically disposed on the outer side of the tube body 122. The second sealing ring 125 is sealed and connected between the plate body 121 and the mounting panel 130. The second sealing ring 125 can further improve the sealing performance of the gap between the plate body 121 and the mounting panel 130 in the first direction D1.

[0095] Continue reading Figures 1 to 5 For example, in a plane perpendicular to the first direction D1, the orthographic projection of the second sealing ring 125 is at least partially located outside the orthographic projection of the via hole 130a. This ensures the effectiveness of the sealing of the second sealing ring 125 between the board body 121 and the mounting panel 130.

[0096] See also Figures 1 to 5 For example, at least one of the plate body 121 and the mounting panel 130 may include a second positioning groove 121e. A portion of the second sealing ring 125 is accommodated in the second positioning groove 121e. The remaining portion of the second sealing ring 125 is located outside the second positioning groove 121e along the first direction D1, so as to be pressed and fitted between the plate body 121 and the mounting panel 130, thereby sealing the gap between the plate body 121 and the mounting panel 130.

[0097] exist Figures 1 to 5 In the example shown, the second positioning groove 121 e is provided on a surface of the plate body 121 adapted to face the mounting panel 130 .

[0098] In other examples not shown, if the plate body 121 is a plastic component, the second sealing component and the plate body 121 can be manufactured as an integral component.

[0099] See also Figures 1 to 8 In addition, the plate body 121 may further include a connection hole 121d extending through the first direction D1. The electronic device 100 may further include a fastening bolt 133 and a fastening nut 134. The fastening bolt 133 is connected to the mounting panel 130 and protrudes from the outer surface of the mounting panel 130 along the first direction D1. The fastening bolt 133 is adapted to be inserted into the connection hole 121d. The fastening bolt 133 is located on a side of the plate body 121 away from the mounting panel 130. And the fastening nut 134 is screwed to the fastening bolt 133 to fasten the adapter connector 120 to the mounting panel 130. Among them, the hole diameter of the connection hole 121d is larger than the outer diameter of the fastening bolt 133. By setting the hole diameter of the connecting hole 121d to be larger than the outer diameter of the fastening bolt 133, it is convenient to adjust the position of the adapter connector 120 in a direction perpendicular to the first direction D1 after the fastening bolt 133 is inserted into the connecting hole 121d, so that the adapter connector 120 can better adapt to the position of the connector body 110 in the through hole 130a, thereby ensuring that the assembly tolerance of the connector body 110 relative to the mounting panel 130 can be absorbed.

[0100] Continue reading Figures 1 to 8 For example, the plate body 121 may include two groups of connection holes 121d. The two groups of connection holes 121d are arranged at intervals along a direction perpendicular to the first direction D1. The electronic device 100 may include two groups of fastening bolts 133 and two groups of fastening nuts 134. The two groups of fastening bolts 133 correspond one to one with the two groups of connection holes 121d. By providing two groups of connection holes 121d and two groups of fastening bolts 133, after the adapter connector 120 is fastened to the mounting panel 130 by the cooperation of the fastening bolts 133 and the fastening nuts 134, the adapter connector 120 can be effectively prevented from deflecting relative to the mounting panel 130, which also helps to enhance the firmness of the connection between the adapter connector 120 and the mounting panel 130.

[0101] exist Figures 1 to 8 In the example shown, the plate body 121 includes two connection holes 121 d. The electronic device 100 includes two fastening bolts 133 and two fastening nuts 134.

[0102] Continue reading Figures 1 to 8 In order to ensure that the second sealing member can achieve reliable sealing, in a plane perpendicular to the first direction D1, the orthographic projection of the connecting hole 121d is located outside the orthographic projection of the second sealing member.

[0103] See also Figures 1 to 8 For example, the mounting panel 130 may include a mounting plate 131 and a reinforcing plate 132. The mounting plate 131 may include a first through hole 131a. The reinforcing plate 132 is located on one side of the mounting plate 131 along the first direction D1. The reinforcing plate 132 is fixed to the mounting plate 131. The reinforcing plate 132 may include a second through hole 132a. The second through hole 132a is arranged corresponding to the first through hole 131a and constitutes the through hole 130a. Among them, the fastening bolt 133 is fixedly connected to the reinforcing plate 132. By providing the reinforcing plate 132, it is possible to choose to first fix the fastening bolt 133 to the reinforcing plate 132, and then fix the reinforcing plate 132 to the mounting plate 131. This can improve the convenience and flexibility of production and manufacturing. Moreover, the strength of the connection structure between the fastening bolt 133 and the mounting panel 130 can also be improved.

[0104] See also Figures 1 to 8 , further, the fastening bolt 133 is welded to the reinforcing plate 132. It can also be welded to the mounting plate 131. The mounting plate 131 and the reinforcing plate 132 can be connected by stir friction welding to achieve a seal between the mounting plate 131 and the reinforcing plate 132. The reinforcing plate 132 is provided with an assembly hole. The fastening bolt 133 is inserted into the assembly hole, and the fastening bolt 133 is fixed to the reinforcing plate 132 by welding or other methods. The reinforcing plate 132 and the mounting plate 131 can be fixedly connected by an assembly method such as friction welding.

[0105] In other examples not shown, the mounting panel 130 may only have the mounting plate 131 , that is, the reinforcing plate 132 may not be provided.

[0106] See also Figures 1 to 5For example, the adapter connector 120 can be a plastic part. The electronic device 100 can also include a support member 124. The support member 124 is an annular member. The support member 124 is connected to the connection hole 121d. The support member 124 is located between the mounting panel 130 and the fastening nut 134. The inner diameter of the support member 124 is larger than the outer diameter of the fastening bolt 133. And the inner diameter of the support member 124 is smaller than the outer diameter of the fastening nut 134. Here, on the basis that the fastening bolt 133 and the fastening nut 134 can fasten the adapter connector 120 to the mounting panel 130, a part of the fastening force is borne by adding the support member 124 to prevent the adapter connector 120 from being squeezed and damaged by the fastening nut 134.

[0107] In some other embodiments, the adapter connector 120 may also be a relatively strong component such as a metal component.

[0108] Compared with the related art, the electronic device 100 of the present invention has the following beneficial effects:

[0109] (1) The connector body 110 is directly soldered on the circuit board 140 as a plug-in. The connector body 110 is small in size and replaces the traditional flexible cable connection method. The processing technology is simple and the cost is low.

[0110] (2) The line end connector 160 is directly assembled with the connector body 110 and has no mandatory association with the transition connector 120. When used in a relatively dry environment, the transition connector 120 can be eliminated to reduce costs.

[0111] (3) The connector body 110 is assembled with the adapter connector 120. The adapter connector 120 absorbs the assembly errors between the circuit board 140 and the through hole 130a of the mounting panel 130 along the first direction D1, the second direction D2 and the third direction D3, thereby solving the sealing problem between the connector body 110 and the mounting panel 130 caused by the assembly errors.

[0112] (4) The connector body 110 may be provided with a dust cover 123. The dust cover 123 is fixedly connected to the adapter connector 120 to prevent loss. During the transportation and maintenance of the electronic device 100, when the line end connector 160 and the connector body 110 are separated, the dust cover 123 can effectively prevent water accumulation in the connector body 110.

[0113] (5) The second electrical end of the connector body 110 is welded to the circuit board 140, and the electrical connection is reliable.

[0114] See also Figures 1 to 9 , the following is a detailed description of an assembly method of the electronic equipment of the utility model:

[0115] 1. Assembly of the connector body 110

[0116] Process 1: The connector body 110 has a first sealing ring 112 at the board end, which can be a rubber and plastic injection molding, or a first positioning groove can be opened for assembly. The connector body 111, the first electrical terminal and the second electrical terminal of the connector body 110 are molded by injection molding, which can meet the design sealing. If the sealing level needs to be increased, a glue groove can be designed between the electrical terminal of the connector body 110 and the plastic shell of the connector body 110, and the glue filling method can be considered to enhance the sealing.

[0117] Process 2: The connector body 110 is directly inserted into the corresponding assembly hole of the circuit board 140, wherein the connector body 110 may have a positioning column (not shown). The positioning column can be fixed to the through hole of the circuit board 140 by screws. By providing the positioning column, the insertion force of the line end connector 160 along the first direction D1 can be withstood, and the stress of the electrical terminals of the circuit board 140 and the connector body 110 can be reduced. After the connector body 110 and the circuit board 140 are plugged in, they can be welded by wave soldering or other welding methods to form an electrical connection between the connector body 110 and the circuit board 140.

[0118] Step 3: After the circuit board 140 and the connector body 110 are assembled, the circuit board 140 is fixed to the base in the housing of the electronic device 100 .

[0119] Process 4: The reinforcing plate 132 and the mounting plate 131 can be formed by stamping processes. First, the reinforcing plate 132 is welded with the fastening bolts 133, and then the reinforcing plate 132 and the mounting plate 131 are welded by friction stir welding. The first through hole 131a of the mounting plate 131 and the second through hole 132a of the reinforcing plate 132 should be aligned.

[0120] Step 5: Assemble the mounting panel 130 in the box mentioned in step 3 along the first direction D1. At this time, the gap between the outer peripheral surface of the connector body 110 and the through hole 130a of the mounting panel 130 is large enough, for example, larger than the tolerance of the circuit board 140 and the mounting panel 130 in the second direction D2 and / or the third direction D3. Taking the adapter connector 120 with the plate body 121 on top and the tube body 122 on the bottom as an example, the first sealing ring 112 can be lower than the mounting panel 130 in the first direction D1. It should be noted that the first sealing ring 112 here can also be higher than the mounting panel 130, but when assembling the mounting panel 130, the first sealing ring 112 needs to be additionally protected to prevent the mounting panel 130 from cutting the sealing ring.

[0121] Step 6: Assemble the adapter connector 120, the second sealing ring 125 and the dust cover 123. The adapter connector 120 can be provided with the second sealing ring 125, for example, it can be formed by injection molding of rubber and plastic. The adapter connector 120 can also be provided with a second positioning groove to assemble the second sealing ring 125. The dust cover 123 and the adapter connector 120 can be formed by injection molding as a whole, or can be a snap-on structure, and the dust cover 123 and the adapter connector 120 are fixedly connected together before leaving the factory.

[0122] Step 7: Assemble the adapter connector 120. Assemble the adapter connector 120 to the through hole 130a of the mounting panel 130 along the first direction D1. The tube body portion 122 of the adapter connector 120 and the outer peripheral surface of the connector body 110 are positioned in a radial direction perpendicular to the first direction D1. The tube body portion 122 of the adapter connector 120 and the outer peripheral surface of the connector body 110 form a seal by the first sealing ring 112. It should be noted that the first sealing ring 112 on the outer peripheral surface of the connector body 110 can also be formed at the same position of the tube body portion 122 of the adapter connector 120 by integral injection molding.

[0123] Step 8: Installation is completed. At this time, a gap is reserved between the end surface of the connector body 110 that is closer to the tube body 122 than the plate body 121 along the first direction D1 and the circuit board 140 to prevent interference between the connector body 110 and the soldering pins on the circuit board 140 .

[0124] Among them, the gap between the outer peripheral surface of the adapter connector 120 and the through hole 130a of the mounting panel 130 is large enough, for example, not less than the tolerance of the circuit board 140 and the mounting panel 130 in the second direction D2 and / or the third direction D3. The gap between the lower end surface of the adapter connector 120 and the first sealing ring 112 in the first direction D1 is large enough, for example, not less than the tolerance of the circuit board 140 and the mounting panel 130 in the first direction D1. In this way, the end surface of the tube body 122 away from the plate body 121 and the first sealing ring 112 can be prevented from being misaligned along the first direction D1, thereby preventing the seal from failing. The gap between the tube body 122 of the adapter connector 120 and the first sealing ring 112 is large enough, for example, not less than the tolerance of the circuit board 140 and the mounting panel 130 in the first direction D1, thereby preventing the seal from failing. Another seal is formed between the adapter connector 120 and the mounting panel 130 by the second sealing ring 125. A sufficient gap is maintained between the second sealing ring 125 and the inner surface of the through hole 130a of the mounting panel 130, for example, the gap is not less than the tolerance of the circuit board 140 and the mounting panel 130 in the second direction D2 and / or the third direction D3, so as to prevent sealing failure. The mounting hole 121c of the adapter connector 120 is a through hole. The gap between the through hole and the fastening bolt 133 is large enough, for example, not less than the tolerance of the circuit board 140 and the mounting panel 130 in the second direction D2 and / or the third direction D3, so as to reserve sufficient installation space for the second sealing ring 125.

[0125] 2. Assembly of line end connector 160

[0126] The wire end connector 160 is assembled with the connector body 110. The housing of the wire end connector 160 is provided with a power rod 161 and a rotating shaft 162. The axis of the rotating shaft 162 constitutes the above-mentioned rotation axis AX.

[0127] The assist lever 161 is engaged with the assist protrusion 111b of the connector body 110. The user rotates the assist lever 161 between the initial position and the end position by operating the hand-held portion of the assist lever 161.

[0128] The mounting hole 121c of the adapter connector 120 includes a first groove. The first groove is used to accommodate the power-assisting protrusion 111b and part of the power-assisting rod 161. The power-assisting rod 161 rotates around the axis of the rotating shaft 162, thereby pulling the power-assisting protrusion 111b of the connector body 110 to couple the line end connector 160 and the connector body 110 into place. During the rotation of the power-assisting rod 161, a sufficient gap is maintained between the outer contour surface of the power-assisting rod 161 and the adapter connector 120. That is, the rotation trajectory of the power-assisting rod 161 from the initial position to the end position is spaced apart from the adapter connector 120. The gap between the rotation trajectory of the power-assisting rod 161 and the adapter connector 120 in the first direction D1 is not less than the tolerance of the circuit board 140 and the mounting panel 130 in the first direction D1.

[0129] During the coupling process between the line end connector 160 and the connector body 110, when the power-assisting rod 161 and the power-assisting protrusion 111b are in contact and subjected to force, the electrical terminal of the line end connector 160 can be inserted into the electrical terminal of the connector body 110 for a certain length. In this way, it can be ensured that the line end connector 160 will not cause the connector body 110 or the pin of the line end connector 160 to be deformed under the cooperation of the power-assisting rod 161 and the power-assisting protrusion 111b. The sealing structure between the line end connector 160 and the connector body 110 is not shown in the figure, and the structure can adopt a conventional sealing structure.
