Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a female connector and a male connector. Background Technology

[0002] An electrical connector is a type of motor system that provides a separable interface for connecting two secondary electronic systems. It bridges two conductors in a circuit, allowing current or signals to flow from one conductor to the other. It is a fundamental component for achieving electrical connections and signal transmission.

[0003] Electrical connectors generally include power connectors (equipped with live, neutral, and ground terminals for power supply) and signal connectors (equipped with signal terminals for signal transmission). Currently, power connectors and signal connectors are usually used separately. This means that when a device needs both power supply and signal transmission, installation space for both power connectors and signal connectors must be provided simultaneously. This results in electrical connectors occupying excessive space in the device, affecting the device's wiring planning and design. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a female connector and a male connector, which have the functions of power transmission and signal transmission, and reduce the space occupied on the equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A female connector includes a female base, on which a live wire terminal block, a neutral wire terminal block, and a ground wire terminal block are provided. The live wire terminal block and the neutral wire terminal block are located below the ground wire terminal block. The bottom of the ground wire terminal block extends to both sides to form a first extension plate and a second extension plate. The first extension plate is located above the live wire terminal block, and the second extension plate is located above the neutral wire terminal block.

[0007] The female end base is also provided with two signal terminals, namely a first signal terminal and a second signal terminal. The first signal terminal is located above the first extension plate, and the second signal terminal is located above the second extension plate.

[0008] The upper two sides of the ground terminal extend upward to form a first side plate and a second side plate; a gap is formed between the signal terminal and the ground terminal block.

[0009] The sidewall of the first signal terminal is connected to the first side plate, and the sidewall of the second signal terminal is connected to the second side plate; the first signal terminal is connected to the first extension plate, and the second signal terminal is connected to the second extension plate.

[0010] The length of the signal terminal in the insertion direction is less than the length of the ground terminal block, the live terminal block, and the neutral terminal block in the insertion direction; the upper end surfaces of the first extension plate and the second extension plate are recessed to form a first guide groove and a second guide groove, respectively.

[0011] The live wire terminal block and the neutral wire terminal block are of the same length in the insertion direction and are shorter than the length of the ground wire terminal block in the insertion direction. The neutral wire terminal block has a neutral wire terminal side plate on the side near the live wire terminal block, and the neutral wire terminal side plate is connected to the ground wire terminal block. The live wire terminal block has a live wire terminal side plate on the side near the neutral wire terminal block, and the live wire terminal side plate is connected to the ground wire terminal block. A gap is formed between the live wire terminal side plate and the neutral wire terminal side plate. The live wire terminal block has a guide groove on the side facing the neutral wire terminal block, and the neutral wire terminal block also has a guide groove on the side facing the live wire terminal block.

[0012] The female end base is also provided with a first annular outer wall, and the live wire terminal block, neutral wire terminal block, ground wire terminal block and two signal terminals are all located inside the first annular outer wall.

[0013] A male connector includes a male base with an insulating body. The insulating body, in conjunction with the male base, forms a live wire terminal cavity, a neutral wire terminal cavity, and a ground wire terminal cavity. The ground wire terminal cavity is located above the neutral wire terminal cavity and the live wire terminal cavity. A live wire conductive terminal is provided inside the live wire terminal cavity, a neutral wire conductive terminal is provided inside the neutral wire terminal cavity, and a ground wire conductive terminal and two signal mating terminals are provided inside the ground wire cavity, with the two signal mating terminals located on both sides of the ground wire conductive terminal.

[0014] The two signal docking terminals are a first signal docking terminal and a second signal docking terminal, respectively. The first signal docking terminal is located above the live wire receiving cavity, and the second signal docking terminal is located above the neutral wire receiving cavity.

[0015] The insulating body includes a second annular outer wall and a live wire terminal fixing plate and a neutral wire terminal fixing plate connected within the second annular outer wall; the live wire terminal fixing plate is disposed between the live wire terminal receiving cavity and the ground wire terminal receiving cavity, and the live wire conductive terminal is installed on the lower end face of the live wire terminal fixing plate; the neutral wire terminal fixing plate is located between the neutral wire terminal receiving cavity and the ground wire terminal receiving cavity, and the neutral wire conductive terminal is installed on the lower end face of the neutral wire terminal fixing plate; the ground wire conductive terminal is installed on the inner side of the second annular outer wall, and the signal docking terminal is connected to the annular outer wall.

[0016] The insulating body also includes an isolation plate connected to the second annular outer wall. The isolation plate is located between the live wire terminal receiving cavity and the neutral wire terminal receiving cavity, and guide blocks are provided on both sides of the isolation plate.

Furthermore, this utility model extends the ground wire terminal block on both sides to form a first extension plate and a second extension plate, and then places the two signal terminals above the first and second extension plates respectively. The first and second extension plates respectively isolate the communication space between the live wire terminal block, neutral wire terminal block, and ground wire terminal block, preventing arcing during hot-plugging of the female connector and avoiding the two signal terminals being affected by arcing, effectively ensuring normal signal transmission from the signal terminals.

[0018] In addition, this invention places the signal mating terminal in the ground terminal cavity of the male connector, so that the male connector can simultaneously perform the functions of power transmission and signal transmission.

[0019] In summary, this utility model enables the connector to perform both power transmission and signal transmission functions through structural design, thereby reducing the space occupied on the equipment. Attached Figure Description

[0043] To further explain the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] In the description of the embodiments of this application, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this application is usually placed in when in use, or the orientation or positional relationship that is commonly understood by those skilled in the art. It is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0045] Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

[0046] In the following embodiments, board connector 100 is a female connector, and corresponding ground base 110 corresponds to a female base; wire connector 200 is a male connector, and wire base 210 is a male base, which can be interchanged when needed.

[0047] like Figure 1-4 As shown, this utility model discloses a board-end connector 100, which includes a board-end base 110. The board-end base 110 is provided with a live wire terminal block 11, a neutral wire terminal block 12, a ground wire terminal block 13, and two signal terminals. The live wire terminal block 11 and the neutral wire terminal block 12 are located below the ground wire terminal block 13. The bottom of the ground wire terminal block 13 extends to both sides to form a first extension plate 131 and a second extension plate 132. The first extension plate 131 is located above the live wire terminal block 11, and the second extension plate 132 is located above the neutral wire terminal block 12. The two signal terminals are a first signal terminal 141 and a second signal terminal 142. The first signal terminal 141 is located above the first extension plate 131, and the second signal terminal 142 is located above the second extension plate 132.

[0048] This invention integrates the live wire terminal block 11, neutral wire terminal block 12, ground wire terminal block 13, and signal terminals into the same board-end base 110, enabling the board-end connector 100 to simultaneously perform power transmission and signal transmission functions, thus reducing the space occupied by the connector on the device. Furthermore, this invention extends the ground wire terminal block 13 on both sides to form a first extension plate 131 and a second extension plate 132, and then positions the two signal terminals above the first extension plate 131 and the second extension plate 132, respectively. The first extension plate 131 and the second extension plate 132 respectively isolate the communication space between the live wire terminal block 11, the neutral wire terminal block 12, and the ground wire terminal block 13, preventing arcing during hot-plugging of the board-end connector 100 and avoiding the two signal terminals from being affected by arcing, effectively ensuring normal signal transmission.

[0049] To better prevent signal terminals from being affected by electric arcs, this invention features a first side plate 133 and a second side plate 134 extending upwards from the upper sides of the ground terminal. A first gap 135 is formed between the first signal terminal 141 and the ground terminal block 13, and a second gap 136 is formed between the second signal terminal 142 and the ground terminal block 13. The first side plate 133, the second side plate 134, and the first and second gaps 135 and 136 isolate the signal terminal from the ground connection terminal. The length of the signal terminal in the insertion direction is less than the length of the ground terminal block 13 in the insertion direction. The upper surfaces of the first extension plate 131 and the second extension plate 132 are recessed to form a first guide groove 1311 and a second guide groove 1321, respectively. Furthermore, the length of the signal terminal in the insertion direction is less than the length of the live wire terminal block 11, the neutral wire terminal block 12, and the ground wire terminal block 13 in the insertion direction. That is, the distance between the front end face of the signal terminal and the board base 110 is less than the distance between the front end face of the live wire terminal block 11, the neutral wire terminal block 12, and the ground wire terminal block 13 and the board base 110.

[0050] The side wall of the first signal terminal 141 is connected to the first side plate 133, and the side wall of the second signal terminal 142 is connected to the second side plate 134; the first signal terminal 141 is connected to the first extension plate 131, and the second signal terminal 142 is connected to the second extension plate 132.

[0051] The upper end surfaces of the first extension plate 131 and the second extension plate 132 are recessed to form a first guide groove 1311 and a second guide groove 1321, respectively. The first guide groove 1311 and the second guide groove 1321 can guide the signal mating terminals of the end plate connector, facilitating the alignment and connection of the two.

[0052] The live wire terminal block 11 and the neutral wire terminal block 12 are of the same length in the insertion direction and are flush with each other on the insertion surface. The lengths of the live wire terminal block 11 and the neutral wire terminal block 12 in the insertion direction are less than or equal to the lengths of the ground wire terminal block 13 in the insertion direction. The neutral wire terminal block 12 has a neutral wire terminal side plate 121 on the side near the live wire terminal block 11, which is connected to the ground wire terminal block 13. The live wire terminal block 11 has a live wire terminal side plate 111 on the side near the neutral wire terminal block 12, which is connected to the ground wire terminal block 13. A third gap 123 is formed between the live wire terminal side plate 111 and the neutral wire terminal side plate 121. The arrangement of the live wire terminal side plate 111, the neutral wire terminal side plate 121, and the third gap 123 can effectively isolate the neutral wire terminal block 12 and the live wire terminal block 11. To facilitate better connection between the board-end connector 100 and the wire-end connector 200, the live wire terminal block 11 is provided with a first guide groove 112 on the side facing the neutral wire terminal block 12, and the neutral wire terminal block 12 is also provided with a second guide groove 122 on the side facing the live wire terminal block 11.

[0053] The length of the signal terminal is less than the length of the neutral / live wire terminal block and less than the length of the grounding terminal block. This arrangement ensures that when the wire-end connector and the board-end connector are inserted, the neutral wire terminal block 12 and the live wire terminal block 11 contact first (the system is not powered at this time), and the signal terminal contacts last. The system is powered on only after the host receives the command. When disconnecting, the signal terminal disconnects first, controlling the host to disconnect the power supply, and then the neutral and live wire terminal blocks of the power supply separate. This last-contact-first-disconnect setting of the signal terminal indirectly achieves the function of safe disconnection while energized, preventing arcing caused by hot-plugging or unplugging the connector.

[0054] In the embodiment, the plate end base 110 is also provided with a first annular outer wall 15, and the live wire terminal block 11, the neutral wire terminal block 12, the ground wire terminal block 13 and the two signal terminals are all provided in the first annular outer wall 15.

[0055] like Figure 5-8 As shown, based on the same inventive concept, this utility model also discloses a wire terminal connector 200, including a wire terminal base 210. An insulating body 21 is provided on the wire terminal base 210. The insulating body 21, together with the wire terminal base 210, forms a live wire terminal receiving cavity 22, a neutral wire terminal receiving cavity 23, and a ground wire terminal receiving cavity 24. The ground wire terminal receiving cavity 24 is located above the neutral wire terminal receiving cavity 23 and the live wire terminal receiving cavity 22. A live wire conductive terminal 221 is provided inside the live wire terminal receiving cavity 22, a neutral wire conductive terminal 231 is provided inside the neutral wire terminal receiving cavity 23, and a ground wire conductive terminal 241 and two signal mating terminals are provided inside the ground wire receiving cavity. The two signal mating terminals are located on both sides of the ground wire conductive terminal 241.

[0056] Specifically, the two signal docking terminals are a first signal docking terminal 251 and a second signal docking terminal 252, with the first signal docking terminal 251 located above the live wire receiving cavity and the second signal docking terminal 252 located above the neutral wire receiving cavity.

[0057] The insulating body 21 includes a second annular outer wall 211 and a live wire terminal fixing plate 212, a neutral wire terminal fixing plate 213, and an isolation plate 214 connected within the second annular outer wall 211. The live wire terminal fixing plate 212 is located between the live wire terminal receiving cavity 22 and the ground wire terminal receiving cavity 24, and the live wire conductive terminal 221 is mounted on the lower end face of the live wire terminal fixing plate 212. The neutral wire terminal fixing plate 213 is located between the neutral wire terminal receiving cavity 23 and the ground wire terminal receiving cavity 24, and the neutral wire conductive terminal 231 is mounted on the lower end face of the neutral wire terminal fixing plate 213. The ground wire conductive terminal 241 is mounted on the inner side of the second annular outer wall 211. Two signal mating terminals are symmetrically arranged on both sides of the ground wire conductive terminal 241 and connected to the annular outer wall. The two signal mating terminals are located below the ground wire conductive terminal 241, and the length of the signal mating terminals in the insertion direction is less than the length of the ground wire conductive terminal 241 in the insertion direction. The isolation plate 214 is located between the live wire terminal receiving cavity 22 and the neutral wire terminal receiving cavity 23, and the isolation plate 214 is provided with a first guide block 2141 and a second guide block 2142 on both sides, which cooperate with the first guide groove 112 and the second guide groove 122 of the board end connector 100.

[0058] This utility model discloses an electrical connector, including the aforementioned board-end connector 100 and wire-end connector 200. When the board-end connector 100 and the wire-end connector 200 are plugged in, the live wire terminal 11, neutral wire terminal 12, and ground wire terminal 13 of the board-end connector 100 are respectively inserted into the live wire terminal receiving cavity 22, neutral wire terminal receiving cavity 23, and ground wire terminal receiving cavity 24 of the wire-end connector 200, and mate with the live wire conductive terminal 221, neutral wire conductor terminal, and ground wire conductive terminal 241. Simultaneously, the first signal terminal 141 and the second signal terminal 142 of the board-end connector 100 are also inserted into the ground wire terminal receiving cavity 24, and connect with the first signal mating terminal 251 and the second signal mating terminal 252 in the ground wire terminal receiving cavity 24.

[0059] In summary, this invention integrates the live wire terminal block 11, neutral wire terminal block 12, ground wire terminal block 13, and signal terminals into the same board-end base 110, enabling the board-end connector 100 to simultaneously perform power transmission and signal transmission functions.
