Description

Technical Field

[0001] This utility model relates to a 40-pin terminal socket. Background Technology

[0002] Terminal sockets are a type of electronic connector, typically used for connections between circuit boards. According to Sogou Encyclopedia, a socket terminal is part of a male / female socket and is used in conjunction with a plug terminal. In use, the wire is crimped and inserted into the other part, which is usually soldered to the PCB board.

[0003] When using terminal sockets, a sealing ring needs to be added to ensure the sealing of the terminal socket and prevent liquid from entering the interior. However, most existing sealing rings adopt a single-layer design, which has only one sealing surface. Therefore, it is less effective in resisting pressure or preventing leakage. When using terminal sockets, the single-layer sealing ring design may not be able to prevent external liquid from entering, which poses certain safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a 40-pin terminal socket that enhances the socket's sealing performance and ensures safe use.

[0005] The technical solution to achieve the purpose of this utility model is as follows: This utility model has a socket body; the socket body includes a shell and terminals, a frame is provided on one side of the shell, and multiple through holes are provided inside the frame for terminals to be inserted through the shell. Multiple terminals are provided and are arranged one-to-one with each through hole. Multiple limiting members are also provided and are arranged one-to-one with each terminal. After each terminal is inserted into the corresponding through hole, it forms an insertion limit in the corresponding through hole under the action of the corresponding limiting member. After each terminal is inserted into the corresponding through hole, one end of each terminal is located in the frame and one end of each terminal extends out of the shell and is arranged on the opposite side of the frame. A double-layer sealing ring is also provided, which can be inserted into the frame and seals the inner wall of the frame. The double-layer sealing ring has multiple through holes corresponding to each through hole and allowing terminals to pass through. A first protruding ring and a second protruding ring are provided on the outer side of the double-layer sealing ring and on the inner wall of each through hole. The first protruding ring and the second protruding ring are arranged closely along the extension direction of the through hole, and a sealing space is formed between the first protruding ring and the second protruding ring for sealing the intruding liquid.

[0006] Furthermore, the limiting component includes a sleeve and multiple elastic cards arranged circumferentially around the axis of the sleeve and fixedly mounted on the upper side wall of the sleeve. The end of each elastic card facing the frame is fixedly mounted on the sleeve, and the end of each elastic card away from the frame extends away from the sleeve. The terminal is provided with a mounting ring groove on a section inside the through hole, into which the sleeve can be fitted. The sleeve is detachably mounted in the mounting ring groove. The hole wall of the through hole is provided with a limiting ring groove that corresponds to the mounting groove and can form a snap-fit ​​limiting engagement with the end of each elastic card away from the frame. The terminal forms an insertion limiting engagement in the through hole through the snap-fit ​​limiting engagement between the limiting ring groove and the elastic card.

[0007] Furthermore, the side wall of the sleeve is provided with an open through groove extending along the extension direction of the sleeve. The sleeve can be deformed through the through groove. The sleeve itself has metallic elasticity. After the sleeve is deformed, it returns to the undeformed state through its own metallic elasticity. The sleeve can be detachably fitted into the mounting ring groove through deformation and its own metallic elasticity.

[0008] Furthermore, the outer casing is provided with multiple mounting slots, each containing an insert nut. One end of the insert nut faces the side of the outer casing with the frame, and the other end faces the opposite side of the outer casing to the frame. A waterproof gasket is also provided on the side of the outer casing with the frame. The waterproof gasket has clearance spaces that correspond one-to-one with each mounting slot and frame. The waterproof gasket is installed on the side of the outer casing with the frame by clearance spaces.

[0009] Furthermore, the outer shell has multiple weight-reducing grooves on the side facing away from the frame to reduce its weight.

The first protruding ring and the second protruding ring are arranged closely in sequence along the extension direction of the perforation. A sealing space is formed between the first protruding ring and the second protruding ring to seal the intruding liquid. The double-layer sealing ring seals the inner wall of the frame and the space between the terminal and the perforation at the same time through the setting of the first protruding ring and the second protruding ring, thereby strengthening the sealing effect, reducing the probability of liquid immersion in the inner wall of the socket, and extending the use effect.

[0011] (2) The limiting component of this utility model includes a sleeve and multiple elastic cards arranged circumferentially around the axis of the sleeve and fixedly mounted on the upper side wall of the sleeve. The end of each elastic card facing the frame is fixedly mounted on the sleeve, and the end of each elastic card away from the frame extends away from the sleeve. The wall of the through hole is provided with a limiting ring groove that corresponds to the mounting groove and can form a snap-fit ​​limiting cooperation with the end of each elastic card away from the frame. The terminal forms an insertion limiting in the through hole through the snap-fit ​​limiting cooperation between the limiting ring groove and the elastic card. Through the snap-fit ​​limiting cooperation between the limiting ring groove and the elastic card, the terminal can be quickly installed in the through hole, which is convenient, fast and efficient.

[0012] (3) The sleeve of this utility model has an open through groove on the side wall that extends along the extension direction of the sleeve. The sleeve can be deformed through the through groove. The sleeve itself has metal elasticity. After the sleeve is deformed, it recovers to the undeformed state through its own metal elasticity.
