[0038] Please refer to Figures 1 to 3 The embodiment of the application provides a mounting box assembly 100. The mounting box assembly 100 comprises a mounting box 10, an electrical terminal 30 and a sealing member 50. The mounting box 10 is provided with a reserved hole 11, and the electrical terminal 30 is mounted in the reserved hole 11. The sealing member 50 is located between the inner side wall 110 of the reserved hole 11 and the outer side wall 301 of the electrical terminal 30, and is sleeved on the outer side wall 301 of the electrical terminal 30. The sealing member 50 is used to seal the gap between the inner side wall 110 of the reserved hole 11 and the outer side wall 301 of the electrical terminal 30.

[0039] Specifically, the installation box 10 is a kind of housing for accommodating and protecting electrical components, including but not limited to the battery box of the earphone 1000 and the function box of the earphone 1000, etc. The material of the installation box 10 includes but is not limited to polypropylene (PP), acrylonitrile butadiene styrene (ABS), and polybutylene terephthalate (PBT), etc.

[0040] The installation box 10 is provided with a reserved hole 11, which communicates the inside and outside of the installation box 10. The cross-sectional shape of the reserved hole 11 can be circular, oval, triangular, quadrilateral, or other polygonal, etc., which is not limited here. In one example, the number of reserved holes 11 can be one, and the electrical connection terminals 30 are all installed in the reserved hole 11. In another example, the number of reserved holes 11 can be at least two, and one electrical connection terminal 30 is installed in each reserved hole 11, so as to increase the density of the electrical connection terminals 30 and improve the electrical connection stability of the installation box assembly 100. In other embodiments, the reserved hole 11 can also install elements such as indicator lights and keys.

[0041] The electrical connection terminal 30 is installed in the reserved hole 11, which is used to realize the electrical connection between the internal elements of the installation box 10 and the external elements of the installation box 10. The electrical connection terminal 30 can be one or more, and in this application, the electrical connection terminal 30 is four, and in other embodiments of this application, the electrical connection terminal 30 can be any other number. The material of the electrical connection terminal 30 can be a conductive material such as copper, aluminum alloy, or nickel, etc. When the electrical connection terminal 30 is more than one, the materials of the plurality of electrical connection terminals 30 can be different.

[0042] It can be understood that in some embodiments, there is a certain difference between the size of the reserved hole 11 and the electrical connection terminal 30, which is a reserved size during installation, so that the electrical connection terminal 30 can be installed in the reserved hole 11. Therefore, after the electrical connection terminal 30 is installed in the reserved hole 11, there is a certain gap between the inner side wall 110 of the reserved hole 11 and the outer side wall 301 of the electrical connection terminal 30.

[0043] The sealing member 50 is arranged between the reserved hole 11 and the electrical terminal 30, and is used to seal the gap between the inner side wall 110 of the reserved hole 11 and the outer side wall 301 of the electrical terminal 30, so as to avoid the fluid flowing into the mounting box 10 from the gap. The sealing member 50 can be made of rubber, silica gel, polypropylene or other materials. The sealing member 50 can be one or multiple, which is not limited in the present application. In the embodiments of the present application, the number of the sealing member 50 corresponds to the number of the electrical terminal 30 and the number of the reserved hole 11. The sealing member 50 can be separately formed and then sleeved on the electrical terminal 30, or can be sleeved on the outer side wall 301 of the electrical terminal 30 in the form of encapsulation, or can be directly formed on the outer side wall 301 of the electrical terminal 30 by a two-color injection molding process. At this time, the materials of the electrical terminal 30 and the sealing member 50 can be the same or different.

[0044] By arranging the sealing member 50 between the inner side wall 110 of the reserved hole 11 and the outer side wall 301 of the electrical terminal 30, the present application can seal the gap between the inner side wall 110 of the reserved hole 11 and the outer side wall 301 of the electrical terminal 30, prevent the fluid from flowing into the mounting box 10 from the gap, and improve the waterproof level of the mounting box 10. In addition, the sealing member 50 has low cost and does not occupy additional installation space.

[0045] Please refer to Figures 4 to 6 In some embodiments, the electrical terminal 30 and the inner side wall 110 of the reserved hole 11 jointly form a deformation space 70, and the deformation space 70 is used to accommodate the sealing member 50. The sealing member 50 abuts against the electrical terminal 30, and the sealing member 50 abuts against the inner side wall 110 of the reserved hole 11, so as to form at least three sealing surfaces.

[0046] Specifically, the deformation space 70 is located between the outer side wall 301 of the electrical terminal 30 and the inner side wall 110 of the reserved hole 11, that is, the space between the outer side wall 301 of the electrical terminal 30 and the inner side wall 110 of the reserved hole 11 can be used as the deformation space 70. The deformation space 70 can accommodate the sealing member 50, so that the sealing member 50 is not easy to roll off the electrical terminal 30 when the electrical terminal 30 is installed. That is, the space between the outer side wall 301 of the electrical terminal 30 and the inner side wall 110 of the reserved hole 11 for installing the sealing member 50 is the deformation space 70. For example, when the deformation space 70 is one, the deformation space 70 is located between the outer side wall 301 of the electrical terminal 30 and the inner side wall 110 of the reserved hole 11. After accommodating the sealing member 50, the sealing member 50 contacts other elements to form a sealing surface, so that the space between the outer side surface 103 of the mounting box 10 and the sealing member 50 in the reserved hole 11 is sealed. Figure 5In the embodiment, the space between the inner side wall of the first sub-hole 111 and the connecting portion 35, the space between the inner side wall of the second sub-hole 112 and the connecting portion 35, and the space between the sealing member 50 and the inner side surface 105 of the mounting box 10 are isolated, so as to achieve the waterproof effect and avoid the fluid flowing from the outer side surface 103 into the inner side surface 105 of the mounting box 10 and the interior of the mounting box 10 through the reserved hole 11.

[0047] The sealing member 50 is in contact with the power terminal 30 and the inner side wall 110 of the reserved hole 11, so as to form at least three sealing surfaces. Specifically, the sealing surfaces can include the surface where the sealing member 50 is in contact with the vertically extending portion of the power terminal 30, the surface where the sealing member 50 is in contact with the laterally extending portion of the outer side wall 301 of the power terminal 30, and the surface where the sealing member 50 is in contact with the inner side wall 110 of the reserved hole 11. Further, the sealing member 50 can be in contact with the portions of the outer side wall 301 of the power terminal 30 in different extending directions, so as to form multiple sealing surfaces, and the sealing member 50 can be in contact with the portions of the inner side wall 110 of the reserved hole 11 in different extending directions, so as to form multiple sealing surfaces. For example, in the installation direction S of the power terminal 30 into the reserved hole 11, the reserved hole 11 includes the first sub-hole 111, the second sub-hole 112, the third sub-hole 113 and the fourth sub-hole 114 in sequence. In an embodiment, the extending directions of the inner side wall of the second sub-hole 112 and the inner side wall of the third sub-hole 113 of the reserved hole 11 are different, so that the sealing member 50 can be in contact with the inner side wall 110 of the first sub-hole 111 to form a first sealing surface, the sealing member 50 can be in contact with the inner side wall 110 of the second sub-hole 112 to form a second sealing surface, and the sealing member 50 can be in contact with the inner side wall 110 of the third sub-hole 113 to form a third sealing surface. In this way, the first sealing surface, the second sealing surface and the third sealing surface are located in different planes, so as to avoid the fluid flowing into the interior of the mounting box 10 in different planes, thereby improving the waterproof effect.

[0048] Please refer to Figure 5 and Figure 7 In an embodiment, the inner side wall 110 of the reserved hole 11 is provided with a first groove 115. In another embodiment, the outer side wall 301 of the body portion 31 is provided with a second groove 311, and the deformation space 70 includes the first groove 115 and / or the second groove 311.

[0049] Specifically, in an embodiment, the first groove 115 includes one, and the first groove 115 can be arranged in one or more of the first sub-hole 111, the second sub-hole 112, the third sub-hole 113 and the fourth sub-hole 114 (for example Figure 6) In another embodiment, the first recess 115 can be multiple. The multiple first recesses 115 can be provided in one or more of the first sub-hole 111, the second sub-hole 112, the third sub-hole 113 and the fourth sub-hole 114. The inner side wall 110 of the reservation hole 11 is provided with the first recess 115, which can allow the reservation hole 11 to have different sizes in the installation direction S to adapt to different power terminals 30. The deformation space 70 includes the first recess 115, which can allow the sealing member 50 to be accommodated in the first recess 115, thereby increasing the contact area between the reservation hole 11 and the sealing member 50, thereby improving the sealing effect.

[0050] Specifically, in one embodiment, the second recess 311 includes one, and the second recess 311 can be provided in one or more of the connecting portion 35, the first sub-portion 313, the second sub-portion 315 and the engaging portion 33 (for example Figure 7 ) In another embodiment, the second recess 311 can be multiple. The multiple second recesses 311 can be provided in one or more of the connecting portion 35, the first sub-portion 313, the second sub-portion 315 and the engaging portion 33. The outer side wall 301 of the body portion 31 is provided with the second recess 311, which can allow the body portion 31 to have different sizes in the installation direction S to adapt to different power terminals 30. The deformation space 70 includes the second recess 311, which can allow the sealing member 50 to be accommodated in the second recess 311, thereby increasing the contact area between the body portion 31 and the sealing member 50, thereby improving the sealing effect.

[0051] The deformation space 70 can be provided in the first recess 115 and the second recess 311, thereby further improving the sealing effect of the installation box 10, and also improving the flexibility of layout and process.

[0052] Please refer to Figure 5 and Figure 6 In some embodiments, in the installation direction S of the power terminal 30 into the reservation hole 11, the reservation hole 11 includes the first sub-hole 111, the second sub-hole 112, the third sub-hole 113 and the fourth sub-hole 114 in sequence. The first sub-hole 111 is close to the outer side surface 103 of the installation box 10, and the fourth sub-hole 114 is close to the inner side surface 105 of the installation box 10. The power terminal 30 includes the body portion 31, the engaging portion 33 and the connecting portion 35, and the connecting portion 35 and the engaging portion 33 are respectively located at opposite ends of the body portion 31. The body portion 31 includes the first sub-portion 313 and the second sub-portion 315 in sequence. The first sub-portion 313 is connected with the connecting portion 35, and the second sub-portion 315 is connected with the engaging portion 33. The first sub-portion 313 is accommodated in the third sub-hole 113, and the deformation space 70 is formed between the first sub-portion 313 and the inner side wall 110 of the third sub-hole 113.

[0053] Specifically, the first sub-hole 111, the second sub-hole 112, the third sub-hole 113 and the fourth sub-hole 114 have no limitation on the size in the mounting direction S and the direction perpendicular to the mounting direction S. The diameter of the first sub-hole 111, the second sub-hole 112, the third sub-hole 113 and the fourth sub-hole 114 can or can not change in the mounting direction S. In the embodiment of the present application, the first sub-hole 111, the third sub-hole 113 and the fourth sub-hole 114 have no change in size in the mounting direction S, which makes it easy for the electrical terminal 30 to be molded. The size of the second sub-hole 112 gradually decreases along the mounting direction S, i.e., the size of the second sub-hole 112 at the joint with the first sub-hole 111 is greater than the size of the second sub-hole 112 at the joint with the third sub-hole 113, which makes it easy for the electrical terminal 30 to be mounted into the reserved hole 11.

[0054] In the mounting direction S, the connecting portion 35 is accommodated in the first sub-hole 111 and the second sub-hole 112, the first sub-portion 313 is accommodated in the third sub-hole 113, the second sub-portion 315 is accommodated in the fourth sub-hole 114, and the clamping portion 33 is clamped to the inner side 105 after passing through the reserved hole 11, so that the electrical terminal 30 can be mounted into the reserved hole 11.

[0055] In an embodiment, the first sub-portion 313 is accommodated in the third sub-hole 113 and forms a deformation space 70 between the inner side wall 110 of the third sub-hole 113 and the first sub-portion 313, and the sealing member 50 is accommodated in the deformation space 70, so that the fluid entering the gap between the inner side wall 110 of the first sub-hole 111 and the inner side wall 110 of the second sub-hole 112 and the outer side wall 301 of the connecting portion 35 can be blocked from entering the gap between the inner side wall 110 of the third sub-hole 113 and the outer side wall 301 of the body portion 31.

[0056] In other embodiments, at least one deformation space 70 can be formed between the inner side wall 110 of the reserved hole 11 and the outer side wall 301 of the electrical terminal 30. For example, the deformation space 70 can be formed between the connecting portion 35 and the inner side wall of the first sub-hole 111, the deformation space 70 can be formed between the connecting portion 35 and the inner side wall 110 of the second sub-hole 112, and the deformation space 70 can be formed between the second sub-portion 315 and the inner side wall 110 of the fourth sub-hole 114, and one sealing member 50 is arranged in each deformation space 70. In this way, the multiple sealing members 50 can block the fluid flowing into the reserved hole 11 multiple times, avoid the fluid entering the inside of the mounting box 10, and thus improve the waterproof level of the mounting box 10.

[0057] In some embodiments, the body portion 31, the engaging portion 33 and the connecting portion 35 are in one-piece structure, i.e., the body portion 31, the engaging portion 33 and the connecting portion 35 are in one integral structure, thereby being able to improve the bonding strength between the body portion 31, the engaging portion 33 and the connecting portion 35, preventing the body portion 31, the engaging portion 33 and the connecting portion 35 from being separated during the operation of the electrical terminal 30, and thereby ensuring the stability and reliability of the electrical terminal 30. In other embodiments, the body portion 31, the engaging portion 33 and the connecting portion 35 are in separate structure, i.e., the body portion 31, the engaging portion 33 and the connecting portion 35 are in at least two different structures. In one example, at least two of the body portion 31, the engaging portion 33 and the connecting portion 35 can be combined together by using a detachable connecting mode, which includes but is not limited to snap connection or threaded connection, etc. In another example, at least two of the body portion 31, the engaging portion 33 and the connecting portion 35 can be combined together by using a non-detachable connecting mode, which includes but is not limited to bonding or welding, etc.

[0058] In some embodiments, the first sub-portion 313 and the second sub-portion 315 are in one-piece structure, i.e., the first sub-portion 313 and the second sub-portion 315 are in one integral structure, thereby being able to improve the bonding strength between the first sub-portion 313 and the second sub-portion 315, preventing the first sub-portion 313 and the second sub-portion 315 from being separated during the operation of the body portion 31, and thereby ensuring the stability and reliability of the body portion 31. In other embodiments, the first sub-portion 313 and the second sub-portion 315 are in separate structure, i.e., the first sub-portion 313 and the second sub-portion 315 are in two different structures. In one example, the first sub-portion 313 and the second sub-portion 315 can be combined together by using a detachable connecting mode, which includes but is not limited to snap connection or threaded connection, etc. In another example, the first sub-portion 313 and the second sub-portion 315 can be combined together by using a non-detachable connecting mode, which includes but is not limited to bonding or welding, etc.

[0059] Referring to Figure 6 In some embodiments, the diameter of the first sub-portion 313 is the same as the diameter of the second sub-portion 315.

[0060] Specifically, the diameter of the first sub-portion 313 is the same as the diameter of the second sub-portion 315, which can facilitate the molding of the electrical terminal 30.

[0061] Referring to Figure 6 In some embodiments, the diameter of the first sub-portion 313 is smaller than the diameter of the second sub-portion 315.

[0062] Specifically, the second sub-portion 315 with a larger diameter can provide a good sealing effect, and can play a certain fluid interception effect after the fluid enters the third sub-hole 113 from the outer side 103 of the mounting box 10, so as to avoid the fluid flowing into the inside of the mounting box 10. In addition, the second sub-portion 315 with a larger diameter can increase the contact area between the second sub-portion 315 and the fourth sub-hole 114, and improve the better mounting strength.

[0063] Referring to Figure 5 and Figure 6 In some embodiments, the fourth sub-hole 114 is in interference fit with the second sub-portion 315.

In addition, the fourth sub-hole 114 is in interference fit with the second sub-portion 315, which can further close the gap between the inner side wall 110 of the fourth sub-hole 114 and the outer side wall 301 of the second sub-portion 315, so as to avoid the fluid flowing into the gap between the inner side wall 110 of the fourth sub-hole 114 and the outer side wall 301 of the second sub-portion 315, thereby improving the sealing effect between the fourth sub-hole 114 and the second sub-portion 315, and improving the overall waterproof effect of the mounting box assembly 100.

[0065] Referring to Figure 5 and Figure 7 In some embodiments, the power terminal 30 further comprises a protruding portion 37, which is arranged along the circumference of the outer side wall 301 of the body portion 31, and the protruding portion 37 is in one-piece structure with the body portion 31, and the protruding portion 37 is in interference fit with the inner side wall 110 of the reserved hole 11.

[0066] Specifically, the protruding portion 37 can be one or more, which is not limited in the present application. In some embodiments, the protruding portion 37 is in one-piece structure with the body portion 31, that is, the protruding portion 37 and the body portion 31 are in one integral structure, thereby improving the bonding strength between the protruding portion 37 and the body portion 31, preventing the protruding portion 37 and the body portion 31 from being separated during the operation of the power terminal 30, so as to ensure the stability and reliability of the operation of the power terminal 30. In other embodiments, the protruding portion 37 is in separate structure with the body portion 31, that is, the protruding portion 37 and the body portion 31 are two different structures. In one example, the protruding portion 37 and the body portion 31 can be combined together by a detachable connection mode, which includes but is not limited to a buckle connection or a threaded connection, etc. In another example, the protruding portion 37 and the body portion 31 can be combined together by a non-detachable connection mode, which includes but is not limited to bonding or welding, etc.

[0067] The protrusion 37 is in interference fit with the inner side wall 110 of the reserved hole 11, which can ensure that the protrusion 37 is tightly fitted with the inner side wall 110 of the reserved hole 11, and improve the connection stability of the protrusion 37 and the inner side wall 110 of the reserved hole 11. In addition, the protrusion 37 is in interference fit with the inner side wall 110 of the reserved hole 11, which can further seal the gap between the outer side wall 301 of the protrusion 37 and the inner side wall 110 of the reserved hole 11, thereby avoiding the flow of fluid into the gap between the outer side wall 301 of the protrusion 37 and the inner side wall 110 of the reserved hole 11, thereby improving the sealing effect between the body portion 31 and the reserved hole 11, and improving the waterproof effect of the entire mounting box assembly 100.

[0068] Referring to Figure 5 and Figure 6 In some embodiments, in the mounting direction of the power terminal 30 into the reserved hole 11, the inner side wall 110 of the reserved hole 11 includes a guide portion 1101, and the longitudinal section of the guide portion 1101 is in the shape of a trapezoid with the upper side being larger than the lower side. The longitudinal section of the engaging portion 33 is also in the shape of a trapezoid with the upper side being larger than the lower side, and the engaging portion 33 cooperates with the guide portion 1101.

[0069] Specifically, in the mounting direction S, the longitudinal sections (i.e., the sections obtained by cutting the guide portion 1101 and the engaging portion 33 perpendicularly to the mounting direction S) of the guide portion 1101 and the engaging portion 33 are in the shape of a trapezoid with the upper side being larger than the lower side. When the power terminal 30 is mounted, the engaging portion 33 cooperates with the shape of the guide portion 1101, and the guide portion 1101 provides a guiding effect, which facilitates the insertion of the engaging portion 33 into the reserved hole 11. In the mounting direction S, the guide portion 1101 can be arranged at any position, i.e., the inner side wall 110 of the first sub-hole 111, the second sub-hole 112, the third sub-hole 113, and the fourth sub-hole 114 can all be provided with the guide portion 1101. In an embodiment, the guide portion 1101 is the inner side wall 110 of the second sub-hole 112. In this way, the inner side wall 110 of the second sub-hole 112 has a guiding effect on the outer side wall 301 of the engaging portion 33, and the inner side wall 110 of the second sub-hole 112 facilitates the mounting of the power terminal 30 into the reserved hole 11 when the power terminal 30 is mounted into the reserved hole 11.

[0070] Referring to Figure 4 , Figure 5 and Figure 6 In some embodiments, the power terminal 30 extends into the mounting box 10 from the reserved hole 11, and the engaging portion 33 cooperates with the inner side surface 105 of the mounting box 10.

[0071] Specifically, the engaging portion 33 engages with the inner side surface 105 of the mounting box 10, so that the power terminal 30 can be firmly mounted on the mounting box 10, and the mounting strength is improved. In addition, when the power terminal 30 is subjected to external force in the direction opposite to the mounting direction S, the surface of the engaging portion 33 that engages with the inner side surface 105 of the mounting box 10 can provide a reaction force, so that the power terminal 30 is prevented from being pulled out of the reserved hole 11.

[0072] Referring to Figure 4 and Figure 5 In some embodiments, the mounting box assembly 100 further comprises a circuit board 80 and an electrical connecting piece 90.

[0073] Specifically, the electrical connecting piece 90 can electrically connect the power terminal 30 and the circuit board 80. The electrical connecting piece 90 can be one or multiple. One electrical connecting piece 90 can correspond to multiple power terminals 30, one electrical connecting piece 90 can correspond to one power terminal 30, or multiple electrical connecting pieces 90 can correspond to one power terminal 30. In the embodiments of the application, one electrical connecting piece 90 corresponds to one power terminal 30. The material of the electrical connecting piece 90 includes but is not limited to copper, aluminum, nickel, etc. The electrical connecting piece 90 electrically connects the power terminal 30 and the circuit board 80, so that the surface mount technology (SMT) is not used to electrically connect the power terminal 30 and the circuit board 80. In this way, the electrical connection between the power terminal 30 and the circuit board 80 is ensured to be stable, and the cost is saved.

[0074] Referring to Figure 4 and Figure 5 In some embodiments, the electrical connecting piece 90 comprises an electrically conductive body 91 and an electrically conductive spring piece 93. The electrically conductive body 91 is mounted on the circuit board 80, and the electrically conductive spring piece 93 extends from the electrically conductive body 91 in a direction away from the circuit board 80, then bends towards the circuit board 80 and forms a protruding portion 931. The protruding portion 931 abuts against the engaging portion 33 of the power terminal 30.

[0075] Specifically, in the embodiments of the present application, the conductive body 91 and the conductive spring 93 are in an integral structure, i.e., the conductive body 91 and the conductive spring 93 are in one whole structure, thereby being able to improve the bonding strength between the conductive body 91 and the conductive spring 93, preventing the conductive body 91 and the conductive spring 93 from being separated during the operation of the electrical connector 90, so as to ensure the stability and reliability of the operation of the electrical connector 90. In other embodiments, the conductive body 91 and the conductive spring 93 are in a split structure, i.e., the conductive body 91 and the conductive spring 93 are in two different structures. In one example, the conductive body 91 and the conductive spring 93 can be combined together by a detachable connection mode, including but not limited to a buckle connection or a threaded connection, etc. In another example, the conductive body 91 and the conductive spring 93 can be combined together by a non-detachable connection mode, including but not limited to adhesion or welding, etc. The conductive spring 93 is in abutment with the clamping portion 33 of the electrical terminal 30 and has a certain elasticity, i.e., the conductive spring 93 can be elastically deformed in the installation direction S to change the relative position of itself and the clamping portion 33, so as to adapt to the clamping portion 33 with different relative positions of the conductive spring 93, ensure the electrical connection with the electrical terminal 30, and thus make the connection of the electrical connector 90 and the electrical terminal 30 more stable.

[0076] Referring to Figure 4 and Figure 5 In some embodiments, the outer side surface 103 of the mounting box 10 is curved, the electrical terminals 30 are a plurality of, and the electrical connectors 90 are a plurality of. At least two electrical connectors 90 have different heights relative to the circuit board 80 at the contact positions of the corresponding electrical terminals 30, so that the outer side surfaces 303 of the plurality of electrical terminals 30 are flush.

[0077] Specifically, the outer side surface 103 of the mounting box 10 is curved, i.e., the outer side surface 103 of the mounting box 10 is non-planar, which can adapt the outer side surface 103 of the mounting box 10 to different environments, such as being able to adapt to the charging box 3000 with different external profiles. The outer side surfaces 303 of the plurality of electrical terminals 30 are flush, which can be well electrically connected with the charging terminals (not shown in the figure) on the charging box 3000. Further, the distances from the outer side surfaces 303 of the plurality of electrical terminals 30 to the outer side surface 103 of the mounting box 10 are the same, which can make the outer surface of the outer side surface 103 of the mounting box 10 flat, avoiding the electrical terminals 30 from protruding and being bumped.
