[0033] Example

[0034] Please refer to Figure 1 and Figure 2A bidirectional conductive connector plug 1 includes a main body 11, and a first sealing member 12, a first conductive member 13, a second conductive member 14, and a second sealing member 15 are sequentially arranged along the length direction of the main body 11. The bidirectional conductive connector plug 1 has a simple and novel structure, and is different from the existing connector plug. The main body 11 of the bidirectional conductive connector is provided with a first sealing member 12 and a second sealing member 15 at intervals, and the first conductive member 13 and the second conductive member 14 for conducting electricity are both located between the first sealing member 12 and the second sealing member 15, so that the conductive contact area of ​​the bidirectional conductive connector plug 1 is all within the sealing area, and a bidirectional seal is achieved, thereby preventing foreign matter or liquid from entering the conductive contact area of ​​the bidirectional conductive connector plug 1 from the direction opposite to the insertion direction of the connector plug, which is beneficial to ensure the conductive stability of the connector assembly.

[0035] The first sealing member 12 is a sealing ring and / or the second sealing member 15 is a sealing ring.

[0036] In this embodiment, the end of the main body 11 away from the first sealing member 12 has a step portion 111, and the second sealing member 15 is a sealing ring, and the sealing ring abuts against the step surface of the step portion 111. It is easy to understand that when the two-way conductive connector plug 1 is matched with the two-way conductive connector socket 2, the second sealing member 15 does not penetrate into the inside of the two-way conductive connector socket 2; when the two-way conductive connector plug 1 is matched with the two-way conductive connector socket 2, the step portion 111 plays a limiting role, thereby avoiding the problem that the two-way conductive connector plug 1 is over-inserted so that the first conductive member 13 / the second conductive member 14 fails to reach the preset position. Of course, in some embodiments, it is also possible that the main body 11 does not have the step portion 111, and in this case, the second sealing member 15 can be selected as a sealing ring. In addition, on other main bodies 11 having the step portion 111, it is also acceptable to select a sealing ring as the second sealing member 15, and in this case, the second sealing member 15 can penetrate into the inside of the two-way conductive connector socket 2. That is to say, whether the main body 11 has the step portion 111 does not have a decisive influence on the selection of the second sealing member 15 .

[0037] Specifically, the first conductive member 13 includes a first contact portion 131 and a first extension portion 132 connected to each other, at least a portion of the first contact portion 131 is exposed to the main body 11, the first extension portion 132 is located in the main body 11, and one end of the first extension portion 132 away from the first contact portion 131 extends out of the main body 11 to form a first connecting portion 133. To improve the stability of the first conductive member 13, preferably, the first contact portion 131 has a plurality of first elastic contact protrusions 134. Of course, in actual products, it is also possible that the first contact portion 131 does not have the first elastic contact protrusion 134, that is, it is also possible that the first conductive member 13 cannot be deformed.

[0038] As a preferred embodiment, the first contact portion 131 is a ring structure or an open ring structure, and the main body 11 is provided with a first limiting groove for limiting the first contact portion 131, which can greatly improve the structural stability of the two-way conductive connector plug 1. It is easy to understand that in some specific products, the first limiting groove can provide a certain deformation margin for the first contact portion 131, so that after the first elastic contact protrusion 134 is pressed, the first contact portion 131 has enough space to deform.

[0039] Similarly, optionally, the second conductive member 14 includes a connected second contact portion 141 and a second extension portion 142, at least a portion of the second contact portion 141 is exposed to the main body 11, the second extension portion 142 is located in the main body 11, and one end of the second extension portion 142 away from the second contact portion 141 extends out of the main body 11 to form a second connecting portion 143. In order to improve the stability of conduction of the first conductive member 13, preferably, the second contact portion 141 has a plurality of second elastic contact protrusions 144.

[0040] The second contact portion 141 is a ring structure or an open ring structure, and the main body 11 is provided with a second limiting groove for limiting the second contact portion 141, which can greatly improve the structural stability of the bidirectional conductive connector plug 1.

[0041] It is easy to understand that the first connection part 133 / the second connection part 143 can be extended from the end surface of the main body 11, or can be extended from the outer wall surface of the main body 11, which can be determined according to actual needs.

[0042] In detail, the main body 11 includes a first structural member 112, a second structural member 113 and a third structural member 114 connected to form an integral structure, a partial area of ​​the first conductive member 13 is located at the boundary between the first structural member 112 and the second structural member 113, and a partial area of ​​the second conductive member 14 is located at the boundary between the second structural member 113 and the third structural member 114. In more detail, the first structural member 112 includes a first base 1121 and a first shaft 1122 connected to each other, the step portion 111 is provided on the first base 1121, the first connection portion 133 and the second connection portion 143 both extend out of the main body 11 from the first base 1121, the first connection portion 133 and the second connection portion 143 are used to electrically connect with external devices, the second structural member 113 is sleeved on the first shaft 1122, the third structural member 114 includes a second base 1131 and a second shaft 1132 connected to each other, the third structural member 114 is sleeved on the second shaft 1132, the first limiting groove is located at the boundary between the second base 1131 and the third structural member 114, and the second limiting groove is located at the boundary between the first base 1121 and the second base 1131. Designing the main body 11 as a combined structure composed of a plurality of structural members can facilitate the assembly of the bidirectional conductive connector plug 1.

[0043] Optionally, the first structural member 112, the second structural member 113 and the third structural member 114 are fixed by gluing with glue 16. In other embodiments, the first structural member 112, the second structural member 113 and the third structural member 114 may also be of other structural forms, which may be specifically designed according to actual needs.

[0044] Please refer to Figures 3 to 5 The present embodiment further provides a bidirectional conductive connector socket 2, which has a plug-in hole for inserting a connector plug, and includes a central terminal 21, and insulating sheets 22 are respectively provided on both sides of the central terminal 21, and an outer terminal 23 is provided on the side of the insulating sheet 22 away from the central terminal 21, and the insulating sheet 22 is used to insulate the central terminal 21 from the outer terminal 23, so as to avoid a short circuit between the two, and the plug-in hole passes through the central terminal 21, the two insulating sheets 22 and the two outer terminals 23. The insulating sheet 22 can be made of plastic.

[0045] The bidirectional conductive connector socket 2 has a simple and novel structure, has a bidirectional opening, can realize bidirectional insertion conduction, and can realize dual-path transmission of signals / electric energy. When one of the paths fails, the other path can be used, and the service life is longer; the overall structure is light and thin, and can be effectively adapted to lightweight wearable devices.

[0046] In order to prevent the connector plug from accidentally detaching from the two-way conductive connector socket 2 and causing disconnection from the two-way conductive connector socket 2, preferably, a clamping groove 211 is provided on the inner peripheral wall of the central terminal 21, and the clamping groove 211 is used to clamp the conductive part of the connector plug.

[0047] To facilitate the processing and manufacturing of the snap-in slot 211, optionally, the central terminal 21 includes a first terminal and a second terminal in contact, the first terminal is located on one side of the second terminal, and the snap-in slot 211 is located at the contact surface between the first terminal and the second terminal. In detail, the entire area of ​​the snap-in slot 211 is located on the first terminal; or, the entire area of ​​the snap-in slot 211 is located on the second terminal; or, a part of the area of ​​the snap-in slot 211 is located on the first terminal, and another part of the area of ​​the snap-in slot 211 is located on the second terminal. Of course, in other embodiments, it is also possible for the central terminal 21 to be an integral structure, which can be selected according to actual needs. In addition, in the actual production process, the first terminal and the second terminal can be welded together to form an integral central terminal 21.

[0048] The outer side of the external terminal 23 has a guide portion 231 for guiding the connector plug to be inserted into the plug-in hole, and the guide portion 231 is in an arc or inclined shape. The guide portion 231 can make it easier for the connector plug to be inserted into the plug-in hole, which is conducive to enhancing the user experience.

[0049] In order to improve the structural stability of the bidirectional conductive connector socket 2, the bidirectional conductive connector socket 2 also includes a fixed body 24, and the fixed body 24 is respectively fixedly connected to the central terminal 21 and the outer terminal 23. Preferably, the insulating sheet 22 is also fixedly connected to the fixed body 24. In the actual production process, the fixed body 24 can be fixedly connected to the central terminal 21, the outer terminal 23 and the insulating sheet 22 through an insert injection molding process.

[0050] In this embodiment, the fixed body 24 is in the shape of a ring frame as a whole, the central terminal 21 and the insulating sheet 22 are both located in the fixed body 24, and at least a portion of the outer terminal 23 is located in the fixed body 24. When only a portion of the outer terminal 23 is located in the fixed body 24, the production consumables of the fixed body 24 can be reduced, thereby reducing the manufacturing cost of the bidirectional conductive connector socket 2.

[0051] To prevent the external terminal 23 from accidentally detaching from the fixed body 24 , optionally, the outer periphery of the external terminal 23 has an embedded edge 232 , and the embedded edge 232 is embedded in the fixed body 24 . The presence of the embedded edge 232 can effectively improve the bonding strength between the external terminal 23 and the fixed body 24 .

[0052] Furthermore, a first positioning structure is provided on the insulating sheet 22, and a second positioning structure cooperating with the first positioning structure is provided on the central terminal 21. The cooperation between the first positioning structure and the second positioning structure can realize the precise positioning of the insulating sheet 22 and the central terminal 21, thereby facilitating subsequent assembly work. The first positioning structure can be a first positioning column or a first positioning hole; similarly, a third positioning structure is provided on the insulating sheet 22, and a fourth positioning structure cooperating with the third positioning structure is provided on the outer terminal 23. The cooperation between the third positioning structure and the fourth positioning structure can realize the precise positioning of the insulating sheet 22 and the outer terminal 23, thereby facilitating subsequent assembly work. The third positioning structure can be a second positioning column or a second positioning hole.

[0053] Please refer to Figure 6 and Figure 7 The present embodiment also provides a bidirectional conductive connector assembly, which includes a matching connector plug and the above-mentioned bidirectional conductive connector socket 2. Preferably, the connector plug is the above-mentioned bidirectional conductive connector plug 1. When the bidirectional conductive connector plug 1 is plugged and connected with the bidirectional conductive connector socket 2, the outer edge of the first sealing member 12 contacts the inner wall of one of the outer terminals 23 to achieve sealing, the second sealing member 15 contacts the other outer terminal 23 to achieve sealing, the first conductive member 13 contacts and conducts with the central terminal 21, and the second conductive member 14 contacts and conducts with the outer terminal 23 that contacts the second sealing member 15. It is easy to understand that it is also possible to select an existing unidirectional plug-in connector plug to cooperate with the bidirectional conductive connector socket 2, but bidirectional sealing cannot be achieved.

[0054] In actual use, it is preferred to set the external terminal 23 as a ground terminal, which can effectively improve the use safety of the two-way conductive connector assembly, or improve the signal leakage of the two-way conductive connector assembly.

[0055] In detail, when the bidirectional conductive connector plug 1 is plugged and connected with the bidirectional conductive connector socket 2, the first elastic contact protrusion 134 on the first conductive member 13 is snapped into the snap-in groove 211, thereby increasing the plug-in and pull-out force between the bidirectional conductive connector plug 1 and the bidirectional conductive connector socket 2, thereby reducing the risk of accidental separation of the bidirectional conductive connector plug 1 and the bidirectional conductive connector socket 2; the second elastic contact protrusion 144 on the second conductive member 14 presses against the external terminal 23 close to the second sealing member 15, thereby achieving stable conduction.

[0056] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
