Description

Technical Field

[0001] This utility model relates to the field of high-current connector technology, specifically a novel high-voltage high-current connector. Background Technology

[0002] High-current connectors are specialized electrical components designed for the high-power transmission requirements of industrial equipment. Their core function is to achieve stable transmission of high currents from 200A to 600A. High-current connectors are widely used in fields such as communication equipment. In outdoor lighting fixtures, high-current connectors ensure the normal operation of high voltage and high current.

[0003] A Chinese utility model patent with authorization announcement number CN205921119U discloses a high-current connector, including a metal outer jacket, a metal claw sleeve located inside the metal outer jacket, and an elastic element. The inner surface of the metal outer jacket has a first inclined surface; the outer surface of the metal claw sleeve has a second inclined surface that pushes against the first inclined surface; the inner surface of the metal claw sleeve forms a clamping channel; the elastic element connects the metal claw sleeve and the metal outer jacket and can drive the metal claw sleeve to slide. The sliding metal claw sleeve, under the pushing action of the first inclined surface against the second inclined surface, narrows the entrance to the clamping channel. This utility model, through the metal outer jacket, the metal claw sleeve located inside the metal outer jacket, and the elastic element located inside the metal outer jacket, can improve current carrying capacity and adapt to use in high-current applications.

[0004] Currently, traditional high-current connectors have the following problems:

[0005] After the male and female plugs inside the current connector are connected, traditional current connectors are mostly made of metal stamping, that is: the male pin is machined from high-conductivity copper, the female body is machined from high-conductivity copper, the spring is stamped, and the gasket is stamped. The contact between the male pin and the inner wall of the female sleeve is high voltage and high current, which leads to high joint resistance and heat generation, making it difficult to ensure the normal operation and safe operation of equipment and cables. Utility Model Content

[0006] The purpose of this invention is to provide a novel high-voltage, high-current connector to solve the problems mentioned in the background section.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0008] This utility model provides a novel high-voltage, high-current connector, comprising a plug; a socket connected to the plug; a spring contact structure disposed on the outside of the plug and located inside the socket; and a gasket structure connected to the inside of the spring contact structure and located on the outside of the bottom of the plug.

[0009] The spring structure has two pairs of inwardly extending interlocking protrusions inside, and the inner side of the interlocking protrusions abuts against and presses against a plug.

[0010] Preferably, the cross-sectional area of ​​the top of the plug is larger than the cross-sectional area of ​​the bottom of the plug, an internal thread groove is provided on the inner side of the top of the plug, and an insertion opening is provided on the bottom side of the top of the plug.

[0011] Preferably, the outer side of the bottom of the spring structure is provided with a plurality of protruding balls, the protruding balls extending into the reserved groove in the inner wall of the socket, and the cross-sectional area formed by the plurality of interlocking protrusions in the middle part of the spring structure is smaller than the cross-sectional area of ​​the upper and lower sides of the spring structure.

[0012] Preferably, a vertical groove is provided on one side of the inner wall of the spring sheet structure, and multiple interlocking protrusions located on the upper and lower sides inside the spring sheet structure are staggered, and one side of the root of the spring sheet structure is spherical.

[0013] Preferably, the cross-sectional area of ​​the bottom side of the gasket structure is larger than the cross-sectional area of ​​the top side of the gasket structure, the top side of the gasket structure extends into the interior of the spring structure, and the bottom side of the gasket structure is located at the bottom of the socket.

[0014] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0015] To address the shortcomings of existing technologies, a B-TO-B board-to-board connector is needed that offers high electrical conductivity, simple and reliable connection, moderate to small size, and stable male-female connection.

[0016] This novel high-voltage, high-current connector, with its simple structure and ease of installation, facilitates user connection and disassembly. Furthermore, during the insertion of the plug and socket within the connector, the multiple inwardly recessed protrusions, staggered on the upper and lower sides of the spring-loaded protrusions, ensure stability and secure positioning of the plug. This prevents displacement and wobbling of the plug due to the squeezing and pushing forces generated during PCB assembly, thus guaranteeing a secure plug-socket connection.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] Please see Figures 1-5 A novel high-voltage, high-current connector includes a plug 10; a socket 20 connected to the plug 10; a spring-loaded structure 30 disposed on the outside of the plug 10 and located on the inside of the socket 20; and a gasket structure 40 connected on the inside of the spring-loaded structure 30 and located on the outside of the bottom of the plug 10. The spring-loaded structure 30 has two pairs of inwardly extending mating protrusions 301 inside, and the plug 10 is pressed against the inside of the mating protrusions 301.

[0028] In practical use, the above solution first installs the two PCB boards on the outer top of the plug 10 and the outer side of the socket 20, respectively. Then, the plug 10 is fixed in place using the spring contact structure 30 and the gasket structure 40, positioning it inside the socket 20. This completes the installation of the high-voltage, high-current connector and the PCB board, offering a simple structure and ease of installation. It facilitates connection and disassembly for users and can adapt to various electrical equipment and cable connection needs. The design of the mating head 301 ensures more stable and secure positioning of the plug 10 during installation, preventing displacement of the plug 10 from affecting conductivity during actual use.

[0029] Preferably, the product structure is a board-to-board connection, B-TO-B structure.

[0030] Preferably, the plug 10 is made of high-conductivity copper and is made entirely using an electroplating silver process.

[0031] Preferably, the socket 20 is made of high-conductivity copper and is made entirely using an electroplating silver process.

[0032] Preferably, the spring structure 30 is made of high-conductivity copper and the whole is made of gold-plated 30U.

[0033] By using special high-conductivity copper materials, the impedance and temperature rise of the plug 10, socket 20 and spring structure 30 can be effectively reduced. At the same time, it has strong corrosion resistance and can be used in harsh environments.

[0034] For details, please refer to the following: Figure 2 The cross-sectional area of ​​the top of the plug 10 is larger than the cross-sectional area of ​​the bottom of the plug 10. An internal thread groove 101 is provided on the inner side of the top of the plug 10, and an insertion opening 102 is provided on the bottom side of the top of the plug 10.

[0035] The novel high-voltage, high-current connector of this utility model, through the design of the insertion port 102, can conveniently and firmly install and position the assembled PCB board. At the same time, the internal thread groove 101 can be used to install a threaded positioning rod through a threaded connection, further ensuring the installation and positioning of the PCB board with a small contact area.

[0036] For details, please refer to the following: Figure 3 , Figure 4 and Figure 5 The outer side of the bottom of the spring structure 30 is provided with several protruding balls 302, which extend into the reserved groove on the inner wall of the socket 20. The cross-sectional area formed by the multiple mating protrusions 301 in the middle part of the spring structure 30 is smaller than the cross-sectional area of ​​the upper and lower sides of the spring structure 30.

[0037] In this design, a vertical groove 303 is provided on one side of the inner wall of the spring sheet structure 30, and multiple interlocking protrusions 301 located on the upper and lower sides inside the spring sheet structure 30 are staggered, and one side of the root of the spring sheet structure 30 is spherical.

[0038] The novel high-voltage, high-current connector of this utility model, through the design of the concave structure in the middle of the spring structure 30, not only facilitates the insertion of the plug 10 through the spring structure 30, but also ensures the stability and firmness of the spring structure 30 during installation and positioning. After positioning and fixing, the plug 10 is not easy to shift or shake.

[0039] For details, please refer to the following: Figure 3 The cross-sectional area of ​​the bottom side of the gasket structure 40 is larger than the cross-sectional area of ​​the top side of the gasket structure 40. The top side of the gasket structure 40 extends into the interior of the spring sheet structure 30, and the bottom side of the gasket structure 40 is located at the bottom of the socket 20.

[0040] This novel high-voltage, high-current connector uses a gasket structure 40 to seal and support the connection between the spring structure 30 and the socket 20, further ensuring the stability of the spring structure 30 after it is installed inside the socket 20. This prevents the spring structure 30 from shifting or shaking when the plug 10 is installed, thus ensuring the secure connection between the spring structure 30 and the plug 10.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
