Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and particularly to a high-speed communication connector for electrical connection. Background Art

[0002] An electrical connector system is used to connect circuits, where generally male contact terminals cooperate with female contact terminals. In the electrical connection of a keyboard, each key on the keyboard circuit board is configured with a plug-in electrical connector, that is, there is a corresponding plug-in electrical connector below each key for electrical connection with the key position button of the key. The key position button of the key consists of a pressing switch and an elastic key component, and the pressing switch is the component that forms an electrical connection with the plug-in electrical connector. When assembling the keyboard circuit board, the pressing switch is installed on the keyboard circuit board by plugging to form an electrical connection. For example, for the keyboard key with the patent number CN213815915U, its pin 210 is plugged into the plug-in electrical connector on the keyboard circuit board to form an electrical connection.

[0003] Currently, the plug-in electrical connectors on the keyboard circuit board basically do not have sealing performance and have poor rust prevention function. That is, its insertion port is directly in communication with the external air, and the pins of the key position button of the key are directly inserted to form an electrical connection. Under the influence of humid weather, water vapor is likely to enter the interior. Since a certain temperature will be generated when connected and energized with the pins, after long-term use, the conductive sheets and pins inside the plug-in electrical connector are prone to rust, resulting in abnormal electrical connection between the pins and the conductive sheets, that is, poor contact, causing the key position button of the key to sometimes malfunction, which is not conducive to the normal use of the keyboard.

[0004] Therefore, it is necessary to propose a high-speed communication connector for electrical connection to improve the electrical connection sealing performance of the electrical connector, and further improve the rust prevention effect of the electrical connector, so as to maintain a long-term electrical connection effect. Summary of the Invention

[0005] In order to solve the above problems, the present invention proposes a high-speed communication connector for electrical connection to improve the electrical connection sealing performance of the electrical connector, and further improve the rust prevention effect of the electrical connector, so as to maintain a long-term electrical connection effect.

[0012] Further, the sealing and rust-proof assembly includes an insulating block and a zinc block. One end of the insulating block is fixedly connected to the middle of the connection terminal piece. The other end of the insulating block forms a sealing connection with one side of the embedded convex shell. The zinc block is embedded in the insulating block and forms a conductive contact with the connection terminal piece. The zinc block faces the inside of the embedded convex shell.

[0013] Furthermore, a connecting plate and an insertion groove are provided in the middle of the connection terminal component. The connecting plate is located on one side of the insertion groove.

[0031] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0032] Please refer to Figures 1-6, the present invention provides a high-speed communication connector for electrical connection, including an insulating housing 1, a sealing tightening cover 2, and a plugging terminal assembly 3. The insulating housing 1 is convexly provided with embedding convex shells 11. There are two embedding convex shells 11, which are respectively located at both ends of the insulating housing 1. There are also two sealing tightening covers 2 and two plugging terminal assemblies 3. The two sealing tightening covers 2 and the two plugging terminal assemblies 3 respectively correspond to the two embedding convex shells 11 one by one. The sealing tightening cover 2 is fixedly and sealingly connected to the embedding convex shell 11. The sealing tightening cover 2 is provided with an elastic tightening part 21, and the elastic tightening part 21 is electrically connected to the embedding convex shell 11. One side of the insulating housing 1 is provided with a side slot 12 extending into the embedding convex shell 11. One end of the plugging terminal assembly 3 is inserted into the embedding convex shell 11 through the side slot 12 and forms a sealing connection with one side of the embedding convex shell 11. The other end of the plugging terminal assembly 3 is fixedly connected to the inner wall of the side slot 12. After the pins of the external components penetrate through the elastic tightening part 21 and are inserted into the embedding convex shell 11 and form a contact electrical connection with the plugging terminal assembly 3, the elastic tightening part 21 can tighten and wrap the side wall of the pins of the external components, so that the internal space of the embedding convex shell 11 is sealed.

[0033] In this embodiment, the insulating housing 1 serves as a fixed structure for the sealing tightening cover 2 and the plugging terminal assembly 3. During assembly, the sealing tightening cover 2 is fixedly connected to the embedding convex shell 11. The sealing tightening cover 2 can be fixedly connected to the embedding convex shell 11 by means of clamping or by means of press riveting. One end of the plugging terminal assembly 3 is received in the embedding convex shell 11 and forms a sealing connection with one side of the embedding convex shell 11. The elastic tightening part 21 provided on the sealing tightening cover 2 is soft and has small holes. The elastic tightening part 21 can tighten and wrap the outer peripheral side of the inserted pin 4. Before the pins of the external components are inserted into the embedding convex shell 11, the elastic tightening part 21 can still be electrically connected to the external air, that is, the elastic tightening part 21 has a small hole that can elastically contract. This small hole is used to guide the insertion of the pins 4 of the external components. After the pins 4 of the external components penetrate through the elastic tightening part 21 and are inserted into the embedding convex shell 11 and form a contact electrical connection with the plugging terminal assembly 3, the pins of the external components stay. The elastic tightening part 21 can tighten and wrap the side wall of the pins 4 of the external components, so that the internal space of the embedding convex shell 11 is sealed. At this time, the internal space of the embedding convex shell 11 is not electrically connected to the external air, and water vapor cannot enter the inside of the embedding convex shell 11. In this way, the rust prevention effect of the plugging terminal assembly 3 and the inserted pins is improved;

[0034] In summary, the high-speed communication connector for electrical connection of the present invention can effectively improve the electrical connection sealing performance of the electrical connector, and further improve the rust prevention effect of the electrical connector, so as to maintain a long-term electrical connection effect.

[0035] In this embodiment, the elastic tightening portion 21 includes an annular frame 211, a first annular elastic diaphragm 212, a second annular elastic diaphragm 213, and a rubber ring 214. Both the first annular elastic diaphragm 212 and the second annular elastic diaphragm 213 are made of rubber material. The outer ring of the first annular elastic diaphragm 212 is fixedly connected to the upper surface of the annular frame 211, and the inner ring of the first annular elastic diaphragm 212 is fixedly connected to the upper surface of the outer ring of the rubber ring 214. The outer ring of the second annular elastic diaphragm 213 is fixedly connected to the lower surface of the annular frame 211, and the inner ring of the second annular elastic diaphragm 213 is fixedly connected to the lower surface of the outer ring of the rubber ring 214. The rubber ring 214 is located in the middle area of the annular frame 211. The sealing tightening cover 2 further includes a cover body 215, and the cover body 215 is fixedly connected to the top of the embedded convex shell 11. The outer ring of the annular frame 211 is fixedly connected to the cover body 215. When assembling the first annular elastic diaphragm 212, the second annular elastic diaphragm 213, and the rubber ring 214, the inner ring of the first annular elastic diaphragm 212 is bonded to the rubber ring 214 through an adhesive, and the inner ring of the second annular elastic diaphragm 213 is also bonded to the rubber ring 214 through an adhesive. The outer ring of the first annular elastic diaphragm 212 is fixedly connected to the upper surface of the annular frame 211 through an adhesive and hot pressing, and the outer ring of the second annular elastic diaphragm 213 is fixedly connected to the lower surface of the annular frame 211 through an adhesive and hot pressing, so that the elastic tightening portion 21 forms a hollow structure. When the lead 4 of an external component is inserted into the embedded convex shell 11, the lead 4 passes through the central small hole of the rubber ring 214, stretching the rubber ring 214. The first annular elastic diaphragm 212 and the second annular elastic diaphragm 213 will adaptively contract as the rubber ring 214 expands, and the process of the rubber ring 214 being stretched is also the process of the rubber ring 214 tightening and wrapping the lead 4.

[0036] In this embodiment, the first annular elastic diaphragm 212 has a conical ring surface structure and is recessed in the direction of the embedded convex shell 11. The recessed shape of the first annular elastic diaphragm 212 can facilitate the distinction between the front and back sides of the sealing tightening cover 2 for easy assembly. At the same time, the recessed direction of the first annular elastic diaphragm 212 is beneficial to guiding the lead 4 of an external component to slide onto the rubber ring 214 and pass through the rubber ring 214 when inserted, avoiding puncturing the first annular elastic diaphragm 212.

[0037] In this embodiment, an avoidance groove 111 is provided at the top of the embedded convex shell 11. The center of the rubber ring 214 is communicated with the avoidance groove 111. The avoidance groove 111 is used to provide a channel for the lead of an external component to insert into the embedded convex shell 11. The size of the avoidance groove 111 is larger than the cross-sectional size of the lead 4 of an external component to facilitate the insertion of various leads 4.

[0038] In this embodiment, the plug-in terminal assembly 3 includes a connection terminal member 31 and a sealing and rust-proof assembly 32. The connection terminal member 31 is made of copper alloy. One end of the sealing and rust-proof assembly 32 is fixedly connected to the middle of the connection terminal member 31 to form an electrical contact. The sealing and rust-proof assembly 32 can prevent rust on the connection terminal member 31 in the form of a primary battery, further improving the rust-proof effect of the plug-in terminal assembly 3. One end of the connection terminal member 31 is received in the embedded convex shell 11, and the sealing and rust-proof assembly 32 forms a sealed connection with one side of the embedded convex shell 11. The other end of the connection terminal member 31 is fixedly connected to the inner wall of the side slot 12. The connection terminal member 31 is used for making contact electrical connection with the pin 4 of an external component. When assembling the plug-in terminal assembly 3, the sealing and rust-proof assembly 32 needs to be assembled with the connection terminal member 31 first. When installing the plug-in terminal assembly 3 on the insulating housing 1, the plug-in terminal assembly 3 is inserted from the side slot 12, so that the sealing and rust-proof assembly 32 forms a sealed connection with one side of the embedded convex shell 11, and one end of the connection terminal member 31 can be received in the embedded convex shell 11 in a sealed manner.

[0039] In this embodiment, the sealing and rust-proof assembly 32 includes an insulating block 321 and a zinc block 322. One end of the insulating block 321 is fixedly connected to the middle of the connection terminal member 31, and the other end of the insulating block 321 forms a sealed connection with one side of the embedded convex shell 11. The zinc block 322 is embedded in the insulating block 321 and forms an electrical contact with the connection terminal member 31, and the zinc block 322 faces into the embedded convex shell 11. The insulating block 321 is made of a plastic material. When manufacturing the sealing and rust-proof assembly 32, the zinc block 322 needs to be embedded in the insulating block 321 first. When assembling the sealing and rust-proof assembly 32 with the connection terminal member 31, the sealing and rust-proof assembly 32 is directly fixed to the middle of the connection terminal member 31. After the fixation is completed, the zinc block 322 will contact the connection terminal member 31. After the sealing and rust-proof assembly 32 is installed in the embedded convex shell 11, the insulating block 321 will block one side of the embedded convex shell 11, preventing air from entering the interior from one side of the embedded convex shell 11. During the conductive use of the connection terminal member 31, there will still be a little air inside the embedded convex shell 11, and the zinc block 322 will form a primary battery reaction with the connection terminal member 31 to ensure that the connection terminal member 31 will not be corroded by the little air inside.

[0040] In this embodiment, a connecting plate 311 and an insertion slot 312 are provided in the middle of the connecting terminal member 31. The connecting plate 311 is located on one side of the insertion slot 312. One end of the insulating block 321 is inserted into the insertion slot 312. A first installation slot 3211 and a second installation slot 3212 are provided in the insulating block 321. The first installation slot 3211 communicates with the second installation slot 3212, and the second installation slot 3212 communicates with the inside of the embedded convex shell 11. The connecting plate 311 is received in the first installation slot 3211, and the zinc block 322 is received in the second installation slot 3212 and forms an electrical contact with the connecting plate 311. In order to facilitate the installation of the insulating block 321, the connecting plate 311 and the insertion slot 312 are provided in the middle of the connecting terminal member 31. The connecting plate 311 is vertically upward with respect to the insertion slot 312. When installing the insulating block 321, the first installation slot 3211 can be directly aligned with the connecting plate 311 and then inserted, so that the connecting plate 311 is fixed in the first installation slot 3211. At the same time, a clamping portion 3213 is provided at one end of the insulating block 321. The clamping portion 3213 penetrates through the insertion slot 312, which improves the stability of the installation of the insulating block 321 and the connecting terminal member 31. In order to facilitate the installation of the zinc block 322, the second installation slot 3212 is provided in the insulating block 321. The zinc block 322 needs to be first embedded into the second installation slot 3212. After the insulating block 321 is installed through the first installation slot 3211 and the connecting plate 311, the zinc block 322 also comes into contact with the connecting plate 311. In order to ensure the contact stability between the zinc block 322 and the connecting plate 311, a clamping slot 3111 is provided on the connecting plate 311. Two elastic contact plates 3221 are provided at one end of the zinc block 322. The two elastic contact plates 3221 are symmetrically arranged. When the zinc block 322 is processed, a single groove is cut at one end of the zinc block 322 by laser cutting to form two elastic contact plates 3221. The two elastic contact plates 3221 are both received in the clamping slot 3111 and abut against the inner wall of the clamping slot 3111 to ensure that the zinc block 322 and the connecting plate 311 can be in stable contact.

[0041] In this embodiment, an embedding side groove 112 is provided on one side of the embedding convex shell 11. One side of the insulating block 321 is received in the embedding side groove 112 and is tightly connected to the groove wall of the embedding side groove 112. The other side of the insulating block 321 is joined to the outer side of the embedding convex shell 11 in the same shape. When the plug-in terminal assembly 3 is installed in the embedding convex shell 11, one side of the insulating block 321 is inserted into the embedding side groove 112 to block the internal space of the embedding convex shell 11, preventing external air from entering the embedding convex shell 11. After one side of the insulating block 321 is inserted into the embedding side groove 112, in order to enable the embedding convex shell 11 to be smoothly inserted into the installation groove of the keyboard circuit board, the other side of the insulating block 321 is joined to the outer side of the embedding convex shell 11 in the same shape. For example, if the embedding convex shell 11 is a cylindrical structure, the other side of the insulating block 321 is an arc-shaped structure with the same diameter as the cylindrical structure.

[0042] In this embodiment, a conductive clamping end 313 is provided at one end of the connection terminal member 31. The conductive clamping end 313 is received in the embedding convex shell 11. The conductive clamping end 313 includes two elastic clamping arc pieces 3131 which are symmetrically arranged. A plurality of spaced elastic clamping strips 31311 are provided on both of the two elastic clamping arc pieces 3131, and the plurality of spaced elastic clamping strips 31311 are arranged in sequence along the elastic clamping arc piece 3131. The conductive clamping end 313 relies on the two elastic clamping arc pieces 3131 to clamp the inserted pin 4 to form a contact-type electrical connection. A clamping groove is provided between the two elastic clamping arc pieces 3131, and the width of the clamping groove is smaller than the width of the inserted pin 4. The pin widths of different external components vary. To ensure that the inserted pin 4 can be clamped over a larger area, a plurality of spaced elastic clamping strips 31311 are provided on the elastic clamping arc piece 3131. After the pin 4 is inserted, the adjacent spaced elastic clamping strips 31311 around the pin 4 can all contact the pin 4, that is, one pin 4 is clamped by a plurality of spaced elastic clamping strips 31311 together, forming a tendency to wrap around the pin 4. Compared with a single conductive sheet, when the single conductive sheet clamps the pin 4, it is a single linear contact, while the arrangement of the plurality of spaced elastic clamping strips 31311 can conduct electricity through a plurality of linear contacts, improving the reliability of the conductive contact.

[0043] In this embodiment, one end of the connection terminal member 31 is provided with a soldering end plate 314. The soldering end plate 314 is arranged in an L shape, and a plurality of solder infiltration holes 3141 are provided on the soldering end plate 314. The soldering end plate 314 is used for soldering with the soldering end of the keyboard circuit board 5. When the present invention is installed on the keyboard circuit board 5, the embedding convex shell 11 is aligned with the through groove 51 of the keyboard circuit board 5. Then, after the embedding convex shell 11 is embedded into the through groove 51, the soldering end plate 314 is soldered to the soldering end of the keyboard circuit board 5. After soldering, the present invention is fixedly connected to the keyboard circuit board 5 and forms an electrical connection with the keyboard circuit board 5. The arrangement of the plurality of solder infiltration holes 3141 enables the soldering end plate 314 to be quickly penetrated by solder, facilitating rapid soldering.

[0044] Of course, the present invention can also have many other embodiments. Based on this embodiment, other embodiments obtained by those of ordinary skill in the art without any creative work belong to the scope protected by the present invention.
