Description

Technical Field

[0001] The present application relates to the technical field of electrical connectors, and in particular to a female electrical connector, and more particularly to a USB Type-C right-angle receptacle connector. Background Art

[0002] This section provides background information related to the present application but this information does not necessarily constitute prior art.

[0003] With the rapid development of industrial technology, USB Type-C connectors are widely used in various electronic devices such as mobile phones, smart watches, tablet computers, photographic equipment, game consoles, routers, electric pens, electronic cigarettes, portable monitoring instruments, etc. Electronic devices are usually equipped with USB Type-C female connectors, and electronic devices are connected to USB male connectors through USB female connectors to realize charging of electronic devices or data exchange with other electronic devices. In the USB Type-C right-angle female connector, the mating direction Y of the female connector and the male connector is usually roughly at right angles to the installation direction of the female connector and the printed circuit board (PCB) assembly.

[0004] The USB Type-C female connector in the related art is provided with a terminal assembly, a main shell arranged on the outside of the terminal assembly, and an outer shell sleeved on the outside of the terminal assembly and the main shell. When the user uses a large force to insert the plug-in portion of the male connector into the traditional USB Type-C female socket, various problems may occur, such as excessive insertion of the plug-in portion of the male connector, resulting in poor contact between the female connector and the male connector, causing the terminal assembly to be misaligned relative to the outer shell, etc. In the related art, the distal end of the outer shell of the female connector is usually provided with a plurality of extensions, a part of which extends in the vertical direction to contact / abut with a part of the accommodating part (insulating rubber core) of the terminal assembly for accommodating the conductive element, so as to limit the movement of the terminal assembly relative to the outer shell, thereby ensuring the relatively accurate positioning of the terminal assembly and the outer shell. However, such a design is likely to occupy the space required for the terminal assembly, thereby greatly reducing the space available at the distal end of the terminal assembly.

[0005] In the related art, after the USB Type-C female connector is assembled into an electronic device, there may be a gap between the female connector and the mounting portion of the housing of the electronic device. Water or dust entering from the socket of the USB Type-C female connector can easily enter the interior of the electronic device from the gap between the main housing and the mounting portion of the electronic device, causing an internal short circuit in the electronic device and poor safety performance. Therefore, the waterproof function of the female connector of the electronic device (such as the USB Type-C charging port) becomes very important. If the electronic device is charged when water vapor enters the inside of the charging port, the electronic device is likely to be burned, and in severe cases, it may cause an explosion, thereby threatening the life safety of the user. The electronic device structure of the related art cannot meet the high requirements of the waterproof function or the waterproof effect is poor, so it is necessary to improve the sealing structure of the electrical connector in order to improve the waterproof performance of the electronic device.

[0006] Therefore, there is an urgent need for a female connector that is more compact in structure, easy to operate and has higher waterproof performance. Summary of the invention

[0007] This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.

[0008] In view of the problems existing in the above conventional technologies, there is a need to improve the relevant female connector to overcome or alleviate all or at least part of the above technical problems.

[0009] The present application provides a female connector for an electronic device, the female connector comprising: a terminal assembly, the terminal assembly comprising a plurality of conductive elements and a containing component for containing the conductive elements, the containing component and the conductive elements being formed as an integral piece; an inner shell, the inner shell being sleeved on at least a portion of an outer side of the containing component; a main shell, the main shell being attached to the outer sides of the inner shell and the terminal assembly; an outer shell, the outer shell being attached to the outer side of the main shell, the proximal end of the main shell extending beyond the proximal end of the outer shell in the mating direction of the female connector and the corresponding male connector; and a first seal, the first seal being attached to the outer side wall of the main shell extending beyond the proximal end of the outer shell, the containing component comprising a first connecting portion connected to the inner shell, the first connecting portion being arranged adjacent to the distal end of the main shell and comprising a concave portion, the inner shell comprising a stop portion engaged with the concave portion, the stop portion being formed as an integral piece with the inner shell.

[0010] According to the female connector for electronic equipment provided by the present application, the stop portion and the inner housing are formed as an integral piece, and the stop portion of the inner housing is engaged with the concave portion of the receiving component of the terminal assembly. When the female connector and the corresponding male connector are mated with each other, the stop portion of the inner housing is engaged with the concave portion of the terminal assembly so that the position of the inner housing relative to the receiving component (such as the insulating rubber core) of the terminal assembly is fixed, thereby effectively preventing the inner housing from shifting relative to the terminal assembly in the mating direction, and preventing the inner housing of the female connector from being misplaced or unexpectedly shifted relative to the terminal assembly due to frequent plugging and unplugging of the plug-in portion of the male connector. For example, when the user uses a large force to insert the plug-in portion of the male connector into the female connector, the terminal assembly can be effectively prevented from separating from the inner housing and coming out from the distal side. In addition, since the inner shell according to the present application includes a stop portion formed as an integral piece with the inner shell, in other words, the stop portion is a part of the inner shell, the inner shell itself is used to firmly attach the inner shell to the terminal assembly, and there is no need to provide additional attachment components, thereby reducing the number of components of the female connector, simplifying the manufacturing process, and making the structure compact while also improving the durability of the female connector, thereby improving the contact stability and connection reliability between the male connector and the female connector.

In addition, the same figure numbers are used in the various drawings to represent the same components. In addition, the terms "first", "second", etc. are only for the purpose of convenience of description and are not to be understood as indicating or implying relative importance or relative order.

[0056] It should also be noted that, for the sake of clarity, not all features of the actual specific implementation are described and shown in the specification and drawings, and in order to avoid unnecessary details obscuring the technical solution that the present application focuses on, only the device structure closely related to the technical solution of the present application is described and shown in the drawings and the specification, while other details that are not closely related to the technical content of the present application and are known to those skilled in the art are omitted.

[0057] Next, an exemplary embodiment of the female connector according to the present application will be described in detail with reference to the accompanying drawings. For clarity and conciseness of the description, the mating direction Y, horizontal direction X and vertical direction Y are marked in the figure. The mating direction Y, horizontal direction X and vertical direction Y are perpendicular to each other. The mating direction Y generally refers to the connection direction between the female connector and the corresponding male connector, that is, the mating direction of the female connector and the corresponding male connector. The horizontal direction X generally refers to the width direction of the female connector. The vertical direction Y generally refers to the height direction of the female connector.

[0058] It should be understood that the terms "vertical", "horizontal", "inside", "outside", "front", "back", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0059] According to the female connector for electronic equipment in an exemplary embodiment of the present application, Figure 1 and Figure 2As shown, the female connector 1 includes: a terminal assembly 10, which includes a plurality of conductive elements 13 and a receiving part 11 for receiving the conductive elements 13, the receiving part 11 and the conductive elements 13 being formed as an integral piece; an inner shell 20, the inner shell 20 being sleeved on at least a portion of the outer side of the receiving part 11; a main shell 30, the main shell 30 being attached to the outer sides of the inner shell 20 and the terminal assembly 10; an outer shell 40, the outer shell 40 being attached to the outer side of the main shell 30, the proximal end of the main shell 30 extending beyond the proximal end of the outer shell 40 in the mating direction Y of the female connector and the corresponding male connector; and a first seal 50, the first seal 50 being attached to the outer side wall of the main shell 30 extending beyond the proximal end of the outer shell 40.

[0060] like Figures 3 to 5 As shown, the accommodating part 11 includes a first connecting portion 110 connected to the inner shell 20, the first connecting portion 110 is arranged to be adjacent to the distal end of the main shell 30 and includes a concave portion, the inner shell 20 includes a stop portion engaged with the concave portion, and the stop portion is formed as an integral piece with the inner shell 20.

[0061] According to the female connector of the exemplary embodiment of the present application, when the female connector and the corresponding male connector are mated with each other, the plug-in portion of the male connector contacts the proximal end surface of the inner housing, and the proximal end surface of the inner housing limits the plug-in portion of the male connector, so that the insertion depth of the plug-in portion can be accurately controlled to avoid over-insertion or under-insertion. The stopper of the inner housing 20 engages with the first connecting portion 110 of the accommodating component 11 (e.g., insulating rubber core) of the terminal assembly 10, so that the inner housing is fixed relative to the accommodating component of the terminal assembly, thereby effectively preventing the inner housing from shifting relative to the terminal assembly along the mating direction Y. In addition, since the inner housing according to the present application includes a stopper formed as an integral part with the inner housing, in other words, the stopper is a part of the inner housing, and there is no need to set an additional attachment component for attaching the inner housing to the terminal assembly, which reduces the number of components of the female connector, simplifies the manufacturing process, and makes the structure compact while also improving the durability of the female connector, thereby improving the contact stability and connection reliability between the male connector and the female connector.

[0062] In addition, by providing the first sealing member 50, a seal is formed between the main shell and the mounting portion of the electronic device, thereby effectively preventing water or dust from entering through the socket of the USB Type-C female connector from entering the interior of the electronic device, avoiding internal short circuits in the electronic device, and improving safety performance.

[0063] It is understood that the expression "proximal end" used in the description of the present application refers to the end of the female connector facing the male connector when the female connector is connected to the corresponding male connector, and the expression "distal end" refers to the end of the female connector facing away from the male connector when the female connector is connected to the corresponding male connector. In other words, the "proximal end" and the "distal end" respectively indicate the opposite ends of the female connector in the mating direction. In addition, the expression "inside" used in the description of the present application refers to the inner side of the inner shell of the female connector.

[0064] In some exemplary embodiments, the stopper can be bent toward the inner side of the inner housing 20 in the assembled state of the female connector to engage with the concave portion of the first connecting portion. In some examples, the inner housing can be bent and deformed, for example, the inner housing can be made of metal.

[0065] In some exemplary embodiments, the inner shell 20 includes a plurality of stop portions, which are arranged on the first side wall 23 and / or on the second side wall 25 of the inner shell 20, and the first side wall 23 is opposite to the second side wall 25 in the vertical direction Z perpendicular to the mating direction Y.

[0066] In some exemplary embodiments, the stopper is formed as an overhanging sheet, for example, the overhanging sheet is a sheet cut from the inner shell 20. Optionally, the slit forming the overhanging sheet is cut from the distal edge of the inner shell 20. Figure 2 and Figure 7 As shown, the overhanging sheet portion includes a first overhanging sheet portion 22 and a second overhanging sheet portion 24 disposed on the first side wall 23 of the inner shell 20, and the first connecting portion 110 includes a first concave portion 111 matched with the first overhanging sheet portion 22 and a second concave portion 113 matched with the second overhanging sheet portion 24, and the first concave portion 111 and the second concave portion 113 are open toward the inner shell 20 in the vertical direction Z. In some examples, the first concave portion 111 and the second concave portion 113 are disposed near the distal edge of the first connecting portion 110.

[0067] In some exemplary embodiments, Fig. 9 and Fig.10 As shown, Fig. 9 FIG. 1 shows a cross-sectional schematic diagram of the first connecting portion 110 and the inner housing 20 when they are not assembled. Fig.10The schematic cross-sectional view of the first connection part 110 and the inner shell 20 in the assembled state is shown.

[0068] In some optional embodiments, such as Fig.10 As shown, the first and second overhanging sheet portions 22 and 24 arranged on the first side wall 23 and the third and fourth overhanging sheet portions 26 and 28 arranged on the second side wall 25 are mirror images about a plane passing through the horizontal center axis B of the inner shell 20 along the horizontal direction X.

[0069] The first free end of the first overhanging sheet portion 22 and the second free end of the second overhanging sheet portion 24 extend toward the inside of the inner housing 20 when the inner housing 20 is assembled with the first connecting portion 110, and are respectively accommodated in the first concave portion 111 and the second concave portion 113. In some examples, the first free end of the first overhanging sheet portion 22 and the second free end of the second overhanging sheet portion 24 are opposite to each other in the horizontal direction X. The length of the first overhanging sheet portion 22 in the horizontal direction is set to be smaller than the length of the first concave portion 111 in the horizontal direction, and the length of the second overhanging sheet portion 24 in the horizontal direction is set to be smaller than the length of the second concave portion 113 in the horizontal direction.

[0070] In some examples, the dimension of the first overhanging sheet portion 22 in the mating direction Y is set to be smaller than the dimension of the inner housing 20 in the mating direction Y. Optionally, the dimension of the first overhanging sheet portion 22 in the mating direction Y is half of the dimension of the inner housing 20 in the mating direction Y.

[0071] In some exemplary embodiments, Fig.10 As shown, the first overhanging sheet portion 22 and the second overhanging sheet portion 24 are mirror images about a plane passing through the vertical center axis A of the inner shell 20 along the vertical direction Z. It should be understood that the number, size, position and arrangement of the overhanging sheet portions and the concave portions are not limited to the specific embodiments shown in the figure, and can be adjusted according to actual conditions.
