[0035] Please refer to Figure 1-Figure 5 The socket 100 provided in the embodiment of the utility model can solve the above-mentioned problem, which will be described in detail below.

[0036] The socket 100 includes a circuit board 110 and a socket module 120 . The circuit board 110 is provided with a positioning slot 111 . The output end 121 of the socket module 120 is embedded in the positioning slot 111 and is electrically connected to the circuit board 110 .

[0037] The socket 100 can be provided with a positioning groove 111 for embedding the output end 121 of the socket module 120 without bending, thereby simplifying the installation steps; and the circuit board 110 can be installed first, and then the output end 121 of the socket module 120 can be installed into the positioning groove 111, thereby avoiding damage to the circuit board 110 due to positioning errors of the socket module 120.

[0038] refer to Figure 1 and Figure 3 The plug module 120 includes a plug kit 125, an inner bracket 126 and a switch 127. The inner bracket 126 is used to fix the plug kit 125. The plug kit 125 extends from the side of the circuit board 110 to form an output end 121. The plug kit 125 extends from the side of the circuit board 110 to form an input end 122. The input end 122 is plugged in with the switch 127 to achieve electrical connection.

[0039] Specifically, the output end 121 is connected to the positioning groove 111 by soldering. Soldering is a welding method that utilizes a low-melting-point metal solder to be heated and melted, and then penetrates into and fills the positioning groove 111 .

[0040] In this embodiment, the number of positioning grooves 111 is two, which are respectively used to electrically connect to the two output terminals 121; of course, in other embodiments of the utility model, the number of positioning grooves 111 can also be one, three, four, etc., and the corresponding number of output terminals 121 can also be one, three, four, and there is no limitation on the specific number of positioning grooves 111 and output terminals 121.

[0041] refer to Figure 1 and Figure 5 In order to further improve the connection stability, the output end 121 may be formed with an anti-slip groove 123 , and the opening direction of the anti-slip groove 123 is set at an angle to the opening direction of the positioning groove 111 .

[0042] Specifically, the opening of the anti-slip groove 123 faces one of the board surfaces of the circuit board 110, that is, the opening of the anti-slip groove 123 and the opening of the positioning groove 111 are perpendicular to each other; of course, the opening of the anti-slip groove 123 and the opening of the positioning groove 111 can also be made at an angle of 60°, 70°, 80°, 100°, 110° and 120°, etc., and the specific angle between the two is not limited.

[0043] refer to Figure 3 and Figure 5A limiting groove 128 is provided on the switch member 127, and a protrusion 124 is formed on the input end 122. The protrusion 124 is accommodated in the limiting groove 128 and is electrically connected to the switch member 127. By providing matching protrusions 124 and limiting grooves 128, the connection stability of the input end 122 can be further improved, and the protrusion 124 is placed in the limiting groove 128 from the height direction, which can prevent the protrusion 124 and the limiting groove 128 from being easily separated.

[0044] During operation, the switch 127 is used to control the on / off of the signal of the input terminal 122 under the action of an external force. Furthermore, in order to facilitate the subsequent matching of soft wires, the input terminal 122 may be provided with a connection hole.

[0045] In this embodiment, the connection hole is a circular hole; in other embodiments of the present invention, the connection hole may also be a rectangle, a triangle, a prism or other shapes, and the specific shape is not limited.

[0046] refer to Figure 3 The socket 100 further includes an interface female socket 140 , which is disposed on the circuit board 110 and electrically connected to the circuit board 110 .

[0047] In this embodiment, in order to improve the convenience of use, the number of interface sockets 140 can be multiple, and the multiple interface sockets 140 are of different types, specifically including a MicroUSB interface, a USB Type C interface, a Lightning interface, a Mini USB interface, etc.

[0048] refer to Figure 1 and Figure 2 The socket 100 also includes a shell 150, which includes a lower shell 1501 and an upper cover 1502. The lower shell 1501 is surrounded by a receiving cavity, and the circuit board 110 and the socket module 120 are both fixed in the receiving cavity. The circuit board 110 and the upper cover 1502 are arranged in parallel, and the socket module 120 is located on one side of the extension direction of the circuit board 110.

[0049] Specifically, in order to improve the convenience of disassembly and assembly, the lower shell 1501 and the upper cover 1502 can be detachably connected 1.

[0050] In addition, a first support portion 151 can be symmetrically arranged on the inner wall of the lower shell 1501, the first support portion 151 abuts against the bottom surface of the circuit board 110, and a positioning buckle 153 is arranged on the side of the first support portion 151 close to the upper cover 1502, and the positioning buckle 153 abuts against the top surface of the circuit board 110.

[0051] During the assembly process of the circuit board 110, the positioning buckle 153 can be squeezed first, and then the bottom surface of the circuit board 110 is brought into contact with the first support portion 151. The positioning buckle 153 is then reset and abutted against the top surface of the circuit board 110, thereby preventing the circuit board 110 from easily detaching from the first support portion 151.

[0052] In this embodiment, two sets of mutually parallel first support portions 151 are disposed at intervals on the inner side wall of the lower housing 1501 , and the first support portions 151 are perpendicular to the upper cover 1502 .

[0053] Of course, in other embodiments of the present invention, the number of the first support parts 151 can also be one, three, five, etc., and the specific number is not limited.

[0054] Referring to the figure, in order to facilitate the connection between the lower shell 1501 and the upper cover 1502, a mounting plate 156 can be provided on the side of the first support portion 151 close to the upper cover 1502. The mounting plate 156 is spaced apart from the inner wall of the lower shell 1501 and forms a card slot. A card hole is provided on the mounting plate 156. The lower end of the upper cover 1502 is provided with a card buckle 157 extending toward the lower shell 1501. The card buckle 157 slides with the card slot and snaps into place with the card hole.

[0055] refer to Figure 2 A first limiting portion 152 is protruded from the side wall of the lower housing 1501 , and the first limiting portion 152 is used to abut against the edge of the circuit board 110 .

[0056] Specifically, the first support portion 151 and the first limiting portion 152 are both convex rib-shaped, and the two cooperate to achieve the fixing effect on the circuit board 110. In addition, compared with the prior art, when fixing the circuit board 110, no fixing frame is required, thereby reducing the number of parts of the socket 100, preventing the components in the housing 150 from being arranged too densely, and thus helping to improve the heat dissipation performance of the circuit board 110.

[0057] When the circuit board 110 is placed in the lower shell 1501, the circuit board 110 can be supported by contacting the first support portion 151, and the circuit board 110 can be limited by cooperating with the first limiting portion 152; in the process of laying the circuit board 110 flat, the positioning buckle 153 will be squeezed, causing the positioning buckle 153 to deform. When the circuit board 110 is laid flat, the positioning buckle 153 will reset under the action of elastic potential energy, and then fasten the top surface of the circuit board 110, thereby realizing pre-positioning of the circuit board 110 and preventing the circuit board 110 from being tilted when the plug module 120 is subsequently assembled.

[0058] At the same time, in order to further improve the position stability of the circuit board 110, a third support portion 158 extending toward the lower shell 1501 may be provided at the lower end of the upper cover 1502. The third support portion 158 corresponds to the first support portion 151. The third support portion 158 is used to abut against the top surface of the circuit board 110 after the upper cover 1502 and the lower shell 1501 are fixed.

[0059] In this embodiment, the third support portion 158 is in the shape of a convex rib. It should be noted that, in order to improve the support stability, the number of the first support portion 151 and the third support portion 158 can be multiple, so as to support multiple positions on the board surface of the circuit board 110 respectively.

[0060] refer to Figure 2 The side wall of the lower shell 1501 is convexly provided with a second supporting portion 154 and a second limiting portion 155 , the second supporting portion 154 is used to support the interface female socket 140 , and the second limiting portion 155 is used to abut against two sides of the interface female socket 140 .

[0061] In order to facilitate cooperation with the interface socket 140, the lower shell 1501 is provided with a plurality of through holes, each of which matches each interface socket 140. The second support portion 154 is located at the lower side of the through hole to support the interface socket 140, and the second limiting portion 155 is located on the left and right sides of the through hole to support the interface socket 140.

[0062] Furthermore, an isolation member 159 is disposed in the lower housing 1501 . The isolation member 159 is located between the circuit board 110 and the socket module 120 and abuts against one side of the circuit board 110 .

[0063] In this embodiment, the isolation member 159 is in the shape of a convex rib and is perpendicular to the inner bottom wall of the lower housing 1501 to facilitate demoulding. The number of the isolation member 159 is one.

[0064] In summary, the socket 100 provided in the embodiment of the present invention has at least the following advantages:

[0065] (1) A positioning groove 111 can be formed on the circuit board 110 to embed the output end 121 of the plug module 120 without bending, thereby simplifying the installation steps; and the circuit board 110 can be installed first, and then the output end 121 can be installed into the positioning groove 111, thereby avoiding damage to the circuit board 110 due to positioning errors of the plug module 120.

[0066] (2) By forming an anti-slip groove 123 at the output end 121 of the socket module 120 and limiting the angle between the opening of the anti-slip groove 123 and the opening of the positioning groove 111, the connection between the output end 121 and the soldering position can be made tighter, thereby improving the relative position stability of the circuit board 110 and the socket module 120.

[0067] (3) The first support portion 151, the first limiting portion 152 and the positioning buckle 153 can be used to pre-position the circuit board 110, so that the circuit board 110 can be installed before the socket module 120, and there is no need to set a fixing frame to fix the circuit board 110, which also improves the heat dissipation performance of the circuit board 110.

[0068] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
