[0002] As a core component in electronic devices that enables electrical connections and signal transmission, connectors' performance and reliability directly affect the stable operation of the entire electronic system.
[0003] Traditional connectors, such as male-female mating connectors, consist of a housing and end plates. The end plates are installed inside the housing and are fixed inside the housing by a metal pin structure.
[0004] However, this structure has a short creepage distance during CQC certification, which can easily lead to leakage problems and pose a safety hazard, resulting in failure to pass CQC certification.
[0005] Therefore, improvements are needed. Utility Model Content
[0006] The technical problem solved by this utility model is to address the deficiencies in the prior art by providing a novel connector to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A novel connector, comprising: a female connector, wherein hook-shaped portions extending outwards are provided on both sides of the female connector; the female connector includes a female housing and a female end strip disposed within the female housing; one or more female protrusions are provided on the inner wall of the female housing, the female protrusions and the female housing being an integral structure, and the female end strip being provided with a first hole for fixing and engaging with the female protrusions; a male connector, wherein hooks are provided on both sides of the male connector for engaging with the hook-shaped portions; at least a portion of the middle part of the hook is connected to the male connector so that the hook can rotate relative to the side wall of the male connector; the male connector includes a male housing and a male end strip disposed within the male housing; one or more male protrusions are provided on the inner wall of the male housing, the male protrusions and the male housing being an integral structure, and the male end strip being provided with a second hole for fixing and engaging with the male protrusions; wherein the female connector and the male connector are made of plastic.
[0008] Furthermore, the female housing is provided with a first stop on one side of the female end row connecting wire; the first stop protrudes from the outline of the opening of the female housing and is used to block and limit the female end row.
[0009] Furthermore, the inner wall of the mother shell is provided with one or more first limiting grooves at the position of the mother end row, and the mother end row is provided with a first protrusion that cooperates with the first limiting groove; when the first limiting groove is placed inside the mother shell, the first protrusion is placed inside the first limiting groove.
[0010] Furthermore, the inner wall of the mother shell is provided with one or more first limiting posts, and the side wall of the mother end row is provided with a first vertical groove that cooperates with the first limiting post. When the mother end row is placed inside the mother shell, the first limiting post cooperates with the first vertical groove.
[0011] Furthermore, the mother housing includes a first housing and a second housing disposed below the first housing, the first housing and the second housing being assembled by a snap-fit structure.
[0012] Furthermore, the male housing has a second stop on one side of the male terminal block connecting wire; the second stop protrudes from the inner wall of the male housing and is used to block and limit the male terminal block.
[0013] Furthermore, the inner wall of the male housing is provided with one or more second limiting grooves at the position of the male end row, and the female end row is provided with a second protrusion that cooperates with the second limiting groove; when the second limiting groove is placed inside the female housing, the second protrusion is placed inside the second limiting groove.
[0014] Furthermore, the inner sidewall of the male housing is provided with one or more second limiting posts, and the sidewall of the male end bar is provided with a second vertical groove that cooperates with the second limiting posts. When the male end bar is placed inside the male housing, the second limiting posts cooperate with the second vertical groove.
[0015] Furthermore, the male housing includes a third housing and a fourth housing disposed below the third housing, the third housing and the fourth housing being assembled by a snap-fit structure.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] Optimized structural design: The female and male connectors are made of plastic, with female and male protrusions integrally molded on them. These protrusions secure the female and male end bars respectively. This one-piece structure replaces traditional metal pins, simplifying the number of parts, reducing assembly steps, avoiding the short-circuit risk associated with metal pins, and further increasing the effective insulation distance. This effectively increases the creepage distance and clearance between critical components, fundamentally reducing the risk of leakage and eliminating safety hazards.
[0018] Multiple limiting structures: Utilizing first and second retaining edges on both the female and male housings, axial blocking is achieved at the wire connection side to prevent the terminal block from dislodging. Limiting grooves and protrusions provide radial horizontal limiting, preventing the terminal block from moving left, right, or forward and backward. Limiting posts and vertical grooves provide radial vertical limiting. This multi-layered, multi-angle fixing scheme ensures the terminal block's position within the housing is absolutely precise and secure, effectively preventing loosening even under vibration or frequent insertion / removal conditions, guaranteeing the long-term stability of the electrical connection.

[0030] In view of the technical problems described in the background art, such as Figure 1-8A novel connector is provided, comprising: a female connector 1, wherein hook-shaped portions 2 extending outwards are provided on both sides of the female connector 1; the female connector 1 includes a female housing 3 and a female end row 4 disposed within the female housing 3; one or more female protrusions 5 are provided on the inner wall of the female housing 3, the female protrusions 5 and the female housing 3 are integrally formed, and the female end row 4 is provided with first holes 6 for fixing and engaging with the female protrusions 5; and a male connector 7, wherein hooks 8 engaging with the hook-shaped portions 2 are provided on both sides of the male connector 7; At least a portion of the middle part of the hook 8 is connected to the male connector 7 so that the hook 8 can rotate relative to the side wall of the male connector 7; the male connector 7 includes a male housing 9 and a male end block 10 disposed within the male housing 9; the inner wall of the male housing 9 is provided with one or more male protrusions 11, the male protrusions 11 and the male housing 9 are integrally formed, and the male end block 10 is provided with a second hole 12 that cooperates with and is fixed to the male protrusions 11; wherein, the female connector 1 and the male connector 7 are made of plastic.
[0031] The novel connector provided by this utility model mainly consists of two parts: a female connector 1 and a male connector 7. Both the female connector 1 and the male connector 7 are made of plastic. This material choice not only reduces costs but also provides good insulation performance, which helps to improve the safety of the connector.
[0032] The female connector 1 and the male connector 7 are detachable. Specifically, hook-shaped portions 2 are provided on both sides of the female connector 1, and corresponding latches 8 are provided on both sides of the male connector 7. The latches 8 and the male connector 7 are integrally formed, with the middle of the latch 8 connected to the male connector 7, giving the latch 8 a certain degree of elasticity. When the male connector 7 and the female connector 1 are inserted and connected, the latches 8 can be hooked on the hook-shaped portions 2 to prevent the male connector 7 from detaching from the female connector 1. When it is necessary to separate the male connector 7 from the female connector 1, external force is applied to the latches 8, causing the latches 8 to disengage from the hook-shaped portions 2, thereby achieving separation.
[0033] The female connector 1 includes a female housing 3 and a female end block 4. The inner wall of the female housing 3 has one or more female protrusions 5, and the female protrusions 5 and the female housing 3 are integrally injection molded. Preferably, the female protrusions 5 are respectively located on the upper and lower inner walls of the female housing 3, and the number of female protrusions 5 can be designed according to the corresponding first hole 6. This integral molding design replaces the traditional metal pins, simplifies the number of parts, reduces assembly steps, and avoids the short circuit risk that may be caused by metal pins. The female end block 4 has a first hole 6 that cooperates with and is fixed to the female protrusions 5. Through the cooperation between the female protrusions 5 and the first hole 6, the female end block 4 is firmly fixed inside the female housing 3.
[0034] The male connector 7 includes a male housing 9 and a male end block 10. One or more male protrusions 11 are provided on the inner wall of the male housing 9, and the male protrusions 11 and the male housing 9 are integrally formed. Preferably, the male protrusions 11 are respectively provided on the upper and lower inner walls of the male housing 9, and the number of male protrusions 11 can be designed according to the second hole position 12. This integrally formed design replaces the traditional metal pin, simplifies the number of parts, reduces assembly steps, and avoids the short circuit risk that may be caused by metal pins.
[0035] like Figure 5-6 As shown, the female housing 3 has a first retaining edge 13 on the side of the female terminal block 4 connected to the wire; the first retaining edge 13 protrudes from the outline of the opening of the female housing 3, and the first retaining edge 13 is used to block and limit the female terminal block 4. The main function of the first retaining edge 13 is to block and limit the female terminal block 4, preventing the female terminal block 4 from coming out of the female housing 3 when the wire is connected, and ensuring the stability of the connection.
[0036] The inner wall of the mother shell 3 is provided with one or more first limiting grooves 14 at the position of the mother end row 4, and the mother end row 4 is provided with a first protrusion 15 that cooperates with the first limiting groove 14; when the first limiting groove 14 is placed inside the mother shell 3, the first protrusion 15 is placed inside the first limiting groove 14.
[0037] The number of first limiting grooves 14 is the same as the number of first protrusions 15 on the female end strip 4. The first protrusions 15 are protruding from the end face of the female end strip 4, and the first limiting grooves 14 are recessed into the inner wall of the female housing 3. The first limiting grooves 14 match the contour of the female end strip 4. When the female end strip 4 is placed inside the female housing 3, the first protrusions 15 are embedded in the first limiting grooves 14. This structure provides radial horizontal limiting, preventing the female end strip 4 from moving left or right or back and forth, and improving the stability of installation.
[0038] The inner wall of the mother shell 3 is provided with one or more first limiting posts 16, and the side wall of the mother end row 4 is provided with a first vertical groove 17 that cooperates with the first limiting post 16. When the mother end row 4 is placed inside the mother shell 3, the first limiting post 16 cooperates with the first vertical groove 17.
[0039] Specifically, first limiting posts 16 are provided on the front and rear side walls of the mother shell 3. The number of first limiting posts 16 is the same as the number of first vertical grooves 17. When the mother end row 4 is placed inside the mother shell 3, the first limiting posts 16 cooperate with the first vertical grooves 17 to provide radial vertical limiting, further ensuring that the mother end row 4 is accurately and firmly positioned inside the mother shell 3.
[0040] like Figure 7-8As shown, the mother shell 3 includes a first shell 18 and a second shell 19 disposed below the first shell 18. The first shell 18 and the second shell 19 are assembled by a snap-fit structure.

The second retaining edge 20 protrudes from the inner wall of the male housing 9 and its function is to block and limit the male terminal block 10, preventing the male terminal block 10 from coming out of the male housing 9 when the wire is connected.
[0043] The inner wall of the male housing 9 is provided with one or more second limiting grooves 21 at the position of the male end row 10, and the female end row 4 is provided with a second protrusion 22 that cooperates with the second limiting groove 21; when the second limiting groove 21 is placed inside the female housing 3, the second protrusion 22 is placed inside the second limiting groove 21.
[0044] The number of second limiting grooves 21 is the same as the number of second protrusions 22 on the male end block 10. The second protrusions 22 are protruding from the end face of the male end block 10, and the second limiting grooves 21 are recessed into the inner wall of the male housing 9. The second limiting grooves 21 match the contour of the male end block 10. When the male end block 10 is placed inside the male housing 9, the second protrusions 22 are embedded in the second limiting grooves 21. This structure provides radial horizontal limiting, preventing the male end block 10 from moving left or right or back and forth, and improving the stability of the installation.
[0045] The male housing 9 has one or more second limiting posts 23 on its inner sidewall, and the male end bar 10 has a second vertical groove 24 on its sidewall that cooperates with the second limiting post 23. When the male end bar 10 is placed inside the male housing 9, the second limiting post 23 cooperates with the second vertical groove 24.
[0046] Specifically, second limiting posts 23 are provided on the front and rear side walls of the male housing 9. The number of second limiting posts 23 is the same as the number of second vertical grooves 24. When the male end strip 10 is placed inside the male housing 9, the second limiting posts 23 cooperate with the second vertical grooves 24 to provide radial vertical limiting, further ensuring that the position of the male end strip 10 inside the male housing 9 is accurate and firm.
[0047] Preferably, the male housing 9 includes a third housing 25 and a fourth housing 26 disposed below the third housing 25, wherein the third housing 25 and the fourth housing 26 are assembled by a snap-fit structure.
[0048] The third housing 25 and the fourth housing 26 are assembled using a snap-fit structure. This assembly method facilitates the assembly and disassembly of the connector, makes it easy for the male terminal block 10 to be installed and embedded in the male housing 9, and also ensures the structural strength of the male housing 9.
[0049] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
