Description

Technical Field

[0001] This application relates to a connector assembly, and more particularly to a connector assembly in which the female connector and the male connector have asymmetrical mating structures, such as insertion slots and insertion portions, so that the female connector and the male connector can be stably and correctly mated. Background Technology

[0002] A connector is a general term for all connecting components and accessories used in the transmission of electronic signals and power. Its main function is to establish and maintain connections between circuits. It is responsible not only for transmitting power but also for transmitting data. It is an important component in any modern electronic system. From mobile phones and computers to large industrial machinery, everything relies on connectors to complete its basic functions.

[0003] Generally, different electronic devices commonly use a structure of male and female connectors to transmit electrical signals or power through mutual plugging. Since these connectors need to withstand vibrations during the operation of electronic devices, stresses during plugging and unplugging, or offset collisions during installation, the alignment accuracy during plugging and the structural stability after plugging become one of the key factors affecting the connection reliability and service life of the connector.

[0004] Furthermore, as electronic systems evolve towards modularity, high density, and multi-interface integration, a single connector often needs to have multiple terminals with different functions or interfaces. Therefore, without an effective foolproof mechanism, users are prone to errors during assembly or maintenance, such as incorrect insertion direction, incorrect insertion position, or incorrect interface type. This can lead to poor electrical contact, signal interference, or even module damage. These problems are particularly pronounced with the trend towards thinner and lighter electronic devices. Therefore, ensuring a stable connection between connectors within a limited space and achieving foolproof protection and interface identification through physical structure is a major issue discussed in this application. Utility Model Content

[0005] In order to stand out in the highly competitive market, the creator, with years of professional experience in the design, processing and manufacturing of various power or signal connectors, and adhering to the spirit of continuous improvement, has finally developed a connector assembly with an asymmetrical connection structure, as well as its female and male connectors, after a long period of research and experimentation. It is hoped that the advent of this application will gain market favor.

[0006] The purpose of this application is to provide a female connector with an asymmetrical connection structure, comprising a female base, multiple first female terminals, and multiple second female terminals. The female base has a insertion slot that can be divided into a first insertion space and a second insertion space along the vertical axis, wherein the maximum widths of the first insertion space and the second insertion space are different along the horizontal axis.

Multiple second male terminals are assembled into the male base, with one end respectively disposed in the second plug portion and the other end extending beyond the male base. Thus, by providing first and second plug portions with different widths in the male base, the insertion direction can be effectively guided, preventing incorrect or reverse insertion, achieving a foolproof structural design, and improving the distinguishability of the different terminal placement areas, thereby enhancing overall connection reliability and assembly efficiency.

[0015] Optionally, the mating surface of the first plug portion is provided with a plurality of first terminal slots, each first terminal slot being used to accommodate one end portion of each first male terminal; the mating surface of the second plug portion is provided with a plurality of second terminal slots, each second terminal slot being used to accommodate one end portion of each second male terminal.

[0042] This application discloses a connector assembly with an asymmetrical joint structure, including its female and male connectors. To facilitate the explanation of the component features and relative positional relationships, the spatial configuration of the assembly is defined in the following description based on three mutually orthogonal axes: the horizontal axis (X-axis), the depth axis (Y-axis), and the vertical axis (Z-axis). Specifically, the horizontal axis (X-axis) refers to the left-right extension direction. Figure 1A The upper left corner is used as the left side direction of the component. Figure 1A The lower right of the component is used as the right side direction; the depth axis (Y-axis) refers to the forward and backward extension direction, where, Figure 1A The lower left corner serves as the front direction of the component. Figure 1A The upper right of the axis is considered the rear direction of the component; the vertical axis (Z-axis) refers to the vertical extension direction. Figure 1A The area above is considered the top (top) side of the component. Figure 1A The area below is used as the bottom (bottom) side direction of the component.

[0043] Please see Figures 1A to 1C As shown, in one embodiment, the connector group C includes a female connector 1 and a male connector 2. The female connector 1 can be connected to one transmission carrier, and the male connector 2 can be connected to another transmission carrier. When the female connector 1 and the male connector 2 are plugged into each other, power and / or signal transmission between the two transmission carriers can be realized. Furthermore, depending on product requirements, the two transmission carriers can be of the same or different types, and can be circuit boards or transmission lines, etc.

[0044] The structure and features of the female connector 1 will be described first here. Please refer to [link / reference]. Figure 2As shown, in this embodiment, the female connector 1 includes a female base 11, multiple first female terminals 13, and multiple second female terminals 15. The female base 11 has a insertion slot 12, which can be divided into a first insertion space 121 and a second insertion space 122 along the vertical axis (Z-axis). The first insertion space 121 is located above the second insertion space 122, and the maximum widths of the first insertion space 121 and the second insertion space 122 along the horizontal axis (X-axis) are different. Figure 3 As shown, the maximum width of the first insertion space 121 is greater than the maximum width of the second insertion space 122. Furthermore, in this embodiment, the first insertion space 121 can be divided into a main insertion area 1211 and four foolproof areas 1213. The main insertion area 1211 is primarily used to configure the distribution area of ​​multiple first female terminals 13 and serves as the main area for insertion with the male connector 2. Each foolproof area 1213 is used to configure a corresponding foolproof structure for the male connector 2 to restrict the insertion direction of the male connector 2.

[0045] Please refer to the above. Figures 1A to 3 As shown, in this embodiment, each of the error-proof areas 1213 is respectively disposed at the corner position of the main insertion area 1211 and extended outward relative to the main insertion area 1211. Thus, through the aforementioned arrangement of the main insertion area 1211 and the error-proof areas 1213, in addition to improving the guidance of the insertion direction and the accuracy of error prevention, space is preserved in the main insertion area 1211, avoiding interference with the arrangement of multiple first female terminals 13, achieving design compatibility such as error prevention and high-density terminal configuration. However, according to actual needs, in other embodiments of this application, the first insertion space 121 can be provided with one or more arbitrary numbers of error-proof areas 1213, or even without error-proof areas 1213, to suit various types of connector products.

[0046] Additionally, please refer to Figures 1A to 2As shown, each of the first female terminals 13 can be assembled onto the female base 11, with one end (e.g., the front end) accommodated in the first insertion space 121, and the other end (e.g., the rear end) extending out of the female base 11. In this embodiment, the section of the first female terminal 13 outside the female base 11 is L-shaped, so that its other end eventually extends downward, but this is not a limitation. In other embodiments of this application, the other section of the first female terminal 13 can extend only in a straight line backward to flexibly adapt to various types of connector products. Furthermore, each of the second female terminals 15 can also be assembled onto the female base 11, with one end accommodated in the second insertion space 122, and the other end extending out of the female base 11. In this embodiment, the section of the second female terminal 15 outside the female base 11 is L-shaped, so that its other end eventually extends downward, but this is not a limitation. In other embodiments of this application, the other segment of the second female terminal 15 may also extend only in a straight line backward. Furthermore, in this embodiment, the first female terminal 13 and the second female terminal 15 correspond to electrical interfaces for different purposes. Specifically, the first female terminal 13 serves as a power terminal to transmit power, and the second female terminal 15 serves as a signal terminal to transmit data signals, but this is not a limitation.

[0047] Furthermore, please refer to Figure 4 As shown, the male connector 2 includes a male base 21, multiple first male terminals 23, and multiple second male terminals 25. The male base 21 has a connector body 22 that mates with the connector slot 12. It can be divided into a first connector portion 221 and a second connector portion 222 along the vertical axis (Z-axis). The first connector portion 221 is located above the second connector portion 222, and the maximum widths of the first connector portion 221 and the second connector portion 222 are different along the horizontal axis. Figure 5 As shown, the maximum width of the first plug-in portion 221 is greater than the maximum width of the second plug-in portion 222. Furthermore, in this embodiment, the first plug-in portion 221 can be divided into a main plug-in block 2211 and four foolproof blocks 2213. The main plug-in block 2211 is mainly used to configure the distribution area of ​​multiple first male terminals 23, serving as the main area for plugging with the female connector 1. Each foolproof block 2213 is used to configure a corresponding foolproof structure (such as a foolproof area 1213) for the female connector 1, ensuring that the male connector 2 maintains the correct insertion direction.

[0048] Please refer to the above. Figures 1A to 5As shown, in this embodiment, each of the anti-misalignment blocks 2213 is located at the corner of the main connector block 2211 and extends outward relative to the main connector block 2211. When the male connector 2 is plugged into the female connector 1, the main connector block 2211 can extend into the main connector area 1211, and each of the anti-misalignment blocks 2213 can extend into its corresponding anti-misalignment area 1213. The second connector portion 222 can then extend into the second connector space 122, ensuring a stable connection between the male connector 2 and the female connector 1. Furthermore, by placing the anti-misalignment blocks 2213 at the corner of the main connector block 2211, space is preserved in the main connector block 2211, preventing any interference with the arrangement of the multiple first male terminals 23. However, depending on actual needs, in other embodiments of this application, the first plug portion 221 can be provided with one or more arbitrary numbers of anti-fooling blocks 2213, or even without anti-fooling blocks 2213, to be suitable for various types of connector products.

[0049] Please also refer to Figures 1A to 1C , Figures 4 to 5 As shown, each of the first male terminals 23 can be assembled onto the male base 21, with one end (e.g., the rear end) located in the first plug-in portion 221 and the other end (e.g., the front end) extending out of the male base 21. In this embodiment, the mating surface of the first plug-in portion 221 is recessed with a plurality of first terminal slots 2210. Each first terminal slot 2210 is used to accommodate one end portion of each of the first male terminals 23 and allows one end portion of the first female terminal 13 of the female connector 1 to extend into it, so that the first male terminal 23 and the first female terminal 13 are electrically connected to each other to transmit power or signals. Furthermore, each of the second male terminals 25 can also be assembled onto the male base 21, with one end located in the second insertion portion 222 and the other end extending out of the male base 21. In this embodiment, the mating surface of the second insertion portion 222 is recessed with a plurality of second terminal slots 2220. Each second terminal slot 2220 is used to accommodate one end portion of each of the second male terminals 25 and allows one end portion of the second female terminal 15 of the female connector 1 to extend into it, so that the second male terminal 25 and the second female terminal 15 are electrically connected to each other to transmit power or signals. In addition, the overall configuration of the first male terminal 23 and the second male terminal 25 can be in various shapes such as L-shape and I-shape according to actual needs, and they can correspond to electrical interfaces for different purposes. Specifically, the first male terminal 23 is used as a power terminal to transmit power, and the second male terminal 25 is used as a signal terminal to transmit data signals, but this is not a limitation.

[0050] For those who would like to make a special mention here, please refer to [the relevant source]. Figures 1A to 5As shown, the term "one end portion" in this application refers to the structural portion included at one end of a component (such as a terminal). This may include the terminal region of that end, or it may encompass an extended region adjacent to that end. For example, if the first male terminal 23 is used to electrically connect to the first female terminal 13, then the portion of the male terminal 23 that contacts the first female terminal 13 is considered one end portion of the first male terminal 23. In other words, while the term "one end portion" in this application is semantically centered on "end," it is not limited to the endpoint or tip, but may also include functional extension sections adjacent to that end (such as structures that contact or insert with mating components) to reasonably cover the physical range in which it functions.

[0051] Furthermore, please refer to Figures 6 to 8 As shown, when the female connector 1 and the male connector 2 are plugged in, in order to ensure accurate alignment and effectively distinguish the terminal areas of different electrical interfaces, the first plugging space 121 and the second plugging space 122 have different main lengths along the depth axis (Y-axis). In this embodiment, as shown... Figure 6 As shown, the first insertion space 121 has a longer (deeper) main length (but is not limited to) compared to the second insertion space 122; similarly, in order to match each other, as Figure 7 As shown, the first insertion portion 221 and the second insertion portion 222 have different principal lengths along the depth axis. Thus, by varying these principal lengths, the terminal areas of different electrical interfaces (e.g., power, signal, etc.) can be effectively distinguished, guiding correct alignment and effectively preventing incorrect insertion or misconnection to different electrical interfaces. It should be specifically noted that the "principal length" referred to in this description refers to the length of the insertion space / insertion portion along the depth axis, extending from the mating surface to each terminal (first / second female terminals 13, 15, first / second male terminals 23, 25) to achieve insertion and electrical connection. It typically does not include sections not designed for insertion, such as the channel in the female base 11 used to accommodate the other end portion of the first / second female terminals 13, 15, and the section in the male base 21 used to house the other end portion of the first / second male terminals 23, 25, etc., which are not included in the aforementioned "principal length".

[0052] In addition, please refer to Figures 1A to 8As shown, in order to improve the positioning stability and identification of the female connector 1 and the male connector 2 during insertion, the connector group C can also be provided with subsequent foolproof features (but not limited thereto). In this embodiment, the inner wall of the top surface of the main insertion area 1211 of the female connector 1 is provided with a plurality of protrusions 1212A, and at least two protrusions 1212A have different configurations from each other; the outer wall of the top surface of the main insertion block 2211 of the male connector 2 is provided with a plurality of grooves 2212A, and at least two grooves 2212A have different configurations from each other; when the female connector 1 and the male connector 2 are inserted, the position of each protrusion 1212A can correspond to each groove 2212A, and they extend into and are accommodated in the corresponding grooves 2212A respectively. Furthermore, when the first / second insertion spaces 121, 122 and the first / second insertion portions 221, 222 have different lengths, the inner wall of the bottom surface of the main insertion area 1211 can also be provided with multiple protrusions 1212B, and the outer wall of the bottom surface of the main insertion block 2211 can be recessed with multiple grooves 2212B, and each of the protrusions 1212B can be accommodated in the corresponding groove 2212B, so as to improve the foolproof effect and increase the insertion stability.

[0053] Continuing from the above, in another embodiment, please refer to Figures 9 to 10 As shown, multiple first female terminals 13 can be arranged in two columns, and each column contains multiple first female terminals 13. The first insertion space 121 is provided with a fitting groove 1214 corresponding to the position between the two columns. Multiple first male terminals 23 can also be arranged in two columns, and each column contains multiple first male terminals 23. The first insertion part 221 is provided with a fitting protrusion 2214 corresponding to the position between the two columns. When the female connector 1 and the male connector 2 are inserted, the position of the fitting protrusion 2214 can correspond to the fitting groove 1214 and can extend into and be accommodated in the fitting groove 1214, thereby improving the foolproof effect and increasing the insertion stability.

[0054] The above description is merely a preferred and feasible embodiment of this application and does not limit the scope of protection of the claims of this application. Therefore, any equivalent changes that can be conceived by those skilled in the art based on the technical content disclosed in this application without creative effort should be included within the scope of protection of the claims of this application.
