[0034] The present utility model provides a female end of a charging connector, which can be applied to various electronic products such as speakers, Bluetooth headsets, electric toothbrushes, etc. This specification only takes a speaker as an example for illustration.

[0035] Please refer to Figures 1 to 3 , Figure 1 which is a schematic structure of an embodiment of the female end of the charging connector provided by the present utility model Figure 1 , Figure 2 which is a cross-section of a partial structure of an embodiment of the female end of the charging connector provided by the present utility model Figure 1 , Figure 3 which is a cross-section of a partial structure of an embodiment of the female end of the charging connector provided by the present utility model Figure 2 。

[0036] In an embodiment of the present utility model, the female end of the charging connector is used to dock with the male end of the charging connector. The female end of the charging connector includes:

[0037] A bracket 100, and a glue injection groove 110 for filling an adhesive is provided on the side of the bracket 100 facing away from the male end of the charging connector;

[0038] Terminal assembly 200, one end of the terminal assembly 200 passes through the bracket 100 to dock with the male charging connector, and the other end of the terminal assembly 200 passes through the glue injection groove 110 and extends in a direction away from the male charging connector; and

[0039] Colloid structure 300, the adhesive is filled in the glue injection groove 110 to form the colloid structure 300, and the terminal assembly 200 is fixed to the bracket 100 through the colloid structure 300.

[0040] The female charging connector in the technical solution of the present utility model includes a bracket 100, a terminal assembly 200 and a colloid assembly. A glue injection groove 110 is provided on the bracket 100. When the terminal assembly 200 passes through the bracket 100, it passes through the glue injection groove 110. The glue injection groove 110 is used to fill the adhesive. After the adhesive solidifies, it forms a colloid structure 300 to connect the terminal assembly 200 and the bracket 100 into one body, and the fixation is firm. The terminal assembly 200 and the bracket 100 are fixed by injecting glue to form the colloid structure 300. The assembly process is simple. Compared with directly injecting the terminal assembly 200 into the bracket 100, the precision requirement for the terminal assembly 200 is lower, and the manufacturing cost is reduced; in addition, since the glue injection groove 110 is provided on the side of the bracket 100 facing away from the male charging connector, the solidified colloid structure 300 is located on the side of the bracket 100 facing away from the male charging connector, and the adhesive is not easily stained on the side of the bracket 100 facing the male charging connector. Therefore, the colloid structure 300 is prevented from affecting the contact conduction between the terminal assembly 200 and the male charging connector, thereby reducing the possibility of poor contact between the female end and the male end.

[0041] In an embodiment, the terminal assembly 200 includes at least one of a first terminal 210, a second terminal 220, and a third terminal 230. One assembly groove 120 is provided on the side of the bracket 100 facing the male charging connector corresponding to each terminal, and each assembly groove 120 communicates with the glue injection groove 110.

[0042] Refer to Figure 2 、 Figure 4 and Figure 5, in an embodiment of the present utility model, the terminal assembly 200 includes at least one of a first terminal 210, a second terminal 220, and a third terminal 230. One of the first terminal 210, the second terminal 220, and the third terminal 230 is a signal terminal, and the other two are a positive terminal and a negative terminal respectively. The terminal assembly 200 may include only one or two of the first terminal 210, the second terminal 220, and the third terminal 230. Multiple charging connector female ends including different terminals are provided on the speaker device to achieve the charging function. For example: three charging connector female ends are provided on the speaker device. The terminal assembly 200 of one charging connector female end is the first terminal 210, the terminal assembly 200 of another charging connector female end is the second terminal 220, and the terminal of the other charging connector female end is the third terminal 230. The terminal assembly 200 may also include all of the first terminal 210, the second terminal 220, and the third terminal 230, and the speaker device can achieve the charging function through one charging connector female end. Of course, multiple first terminals 210, second terminals 220, and third terminals 230 may also be provided. For example: the terminal assembly 200 of the charging connector female end includes one first terminal 210, two second terminals 220, and two third terminals 230, a total of five terminals. One first terminal 210 serves as the signal terminal, the two second terminals 220 together serve as the positive terminal, and the two third terminals 230 together serve as the negative terminal.

[0043] Refer to Figure 5 and Figure 6, in the embodiment of the present utility model, the bracket 100 is provided with an assembly groove 120 corresponding to each terminal. First, the terminal is installed in the corresponding assembly groove 120, and then an adhesive is filled into the glue injection groove 110 to form a colloid structure 300. On the one hand, the provision of the assembly groove 120 facilitates the positioning of each terminal of the terminal assembly 200 on the bracket 100, thereby improving the assembly efficiency of the terminal assembly 200 and the bracket 100; on the other hand, the terminal installed in the assembly groove 120 is not prone to movement, which is beneficial to improving the filling effect of the adhesive, so that the solidified colloid structure 300 firmly fixes each terminal to the bracket 100, thereby ensuring the stability of the terminal assembly 200 and further reducing the possibility of poor contact between the female end of the charging connector and the male end of the charging connector. Specifically, a first assembly groove 121 is provided on one side of the bracket 100 facing the male end of the charging connector corresponding to the first terminal 210. One end of the first terminal 210 passes through the first assembly groove 121, and the other end of the first terminal 210 passes through the colloid structure 300 and extends in a direction away from the male end of the charging connector; a second assembly groove 122 is provided on one side of the bracket 100 facing the male end of the charging connector corresponding to the second terminal 220. One end of the second terminal 220 passes through the second assembly groove 122, and the other end of the second terminal 220 passes through the colloid structure 300 and extends in a direction away from the male end of the charging connector; a third assembly groove 123 is provided on one side of the bracket 100 facing the male end of the charging connector corresponding to the third terminal 230. One end of the third terminal 230 passes through the third assembly groove 123, and the other end of the third terminal 230 passes through the colloid structure 300 and extends in a direction away from the male end of the charging connector.

[0044] In one embodiment, the glue injection groove 110 includes a glue injection sub-groove 111 and a plurality of glue injection holes 112 communicating with the glue injection sub-groove 111. Each assembly groove 120 corresponds to at least one communicating glue injection hole 112.

[0045] Refer to Figures 3 to 5, in an embodiment of the present utility model, the glue injection groove 110 includes a glue injection sub-groove 111 and a plurality of glue injection holes 112. Each assembly groove 120 communicates with the glue injection sub-groove 111 through at least one glue injection hole 112. That is to say, each assembly groove 120 can communicate with the glue injection sub-groove 111 through one glue injection hole 112 or through a plurality of glue injection holes 112. Among them, the first terminal 210, the second terminal 220, and the third terminal 230 all pass through the colloid structure 300 in the glue injection sub-groove 111, so that the first terminal 210, the second terminal 220, the third terminal 230, and the colloid structure 300 form an integral structure, improving the stability and firmness of the terminal assembly 200 on the bracket 100. When each assembly groove 120 communicates with the glue injection sub-groove 111 through a plurality of glue injection holes 112, the terminals in the assembly groove 120 are simultaneously connected to the colloid structures 300 in the corresponding plurality of glue injection holes 112, increasing the connection area between the colloid structure 300 and the terminals, thereby increasing the connection strength between the terminal assembly 200 and the colloid structure 300 and reducing the possibility of the terminal assembly 200 moving or falling off. Specifically in this embodiment, the glue injection hole 112 connecting the first assembly groove 121 and the glue injection sub-groove 111 is the first glue injection hole 1121, and the first terminal 210 is disposed through the first glue injection hole 1121; the glue injection hole 112 connecting the second assembly groove 122 and the glue injection sub-groove 111 is the second glue injection hole 1122, and there are two second glue injection holes 1122. The first pin portion 222 of the second terminal 220 passes through one of the second glue injection holes 1122, and the first reinforcing portion 223 of the second terminal 220 penetrates into the interior of the other second glue injection hole 1122; the glue injection hole 112 connecting the third assembly groove 123 and the glue injection sub-groove 111 is the third glue injection hole 1123, and there are two third glue injection holes 1123. The second pin portion 232 of the third terminal 230 passes through one of the third glue injection holes 1123, and the second reinforcing portion 233 of the third terminal 230 penetrates into the interior of the other third glue injection hole 1123.

[0047] Referring to Figure 3 and Figure 4 , in an embodiment of the present utility model, a glue blocking protrusion 130 is provided around the periphery of the glue injection sub-groove 111. The glue blocking protrusion 130 limits the flow range of the adhesive, prevents the adhesive from overflowing to unnecessary areas, and keeps the appearance of the product clean.

[0048] In an embodiment, a step structure 212 is provided on the outer peripheral wall of the first terminal 210; and / or,

[0049] One end of the first terminal 210 away from the assembly groove 120 is provided with a first wiring hole 211.

[0050] Referring to Figure 6 , in an embodiment of the present utility model, the first terminal 210 is cylindrical, and a stepped structure 212 is provided on the outer peripheral wall of the first terminal 210, such that the diameter of the part of the first terminal 210 located inside the first assembly groove 121 is greater than the diameter of the part of the first terminal 210 located inside the glue injection groove 110. When the first terminal 210 passes through the assembly groove 120 and the glue injection groove 110, the stepped structure 212 plays a limiting role, which not only improves the assembly efficiency but also improves the positioning accuracy of the first terminal 210 on the bracket 100.

[0051] Referring to Figure 2 , in an embodiment of the present utility model, one end of the first terminal 210 away from the assembly groove 120 is provided with a first wiring hole 211, which facilitates the connection of the first wire 410 of the cable assembly 400 and improves the connection strength between the first terminal 210 and the cable assembly 400, thereby improving the conduction stability of the female end of the charging connector. Specifically, the first wiring hole 211 extends along the axial direction of the first terminal 210, with a simple structure and easy processing. After the first wire 410 is inserted into the first wiring hole 211, it is fixed by welding, and the assembly is convenient.

[0055] Referring to Figure 2 and Figure 6 , in an embodiment of the present utility model, the second terminal 220 includes a first docking portion 221 and a first pin portion 222. The first docking portion 221 is used for docking with the male end of the charging connector, and the first pin portion 222 is used for connecting the cable assembly 400. The first docking portion 221 is annularly arranged, increasing the docking area between the second terminal 220 and the male end of the charging connector, and further reducing the possibility of poor contact between the female end of the charging connector and the male end of the charging connector.

[0056] In one embodiment, the second terminal 220 further includes a first strengthening portion 223. One end of the first strengthening portion 223 is connected to the first docking portion 221 and is spaced from the first pin portion 222, and the other end of the first strengthening portion 223 penetrates into the colloid structure 300; and / or,
