Description

Technical Field

[0002] Wafer connector usually refers to the connector base (chip holder) connector, which is generally assembled from metal parts and plastic parts. Unlike hoses that only have plastic parts (some have iron shells), it is assembled from wires and terminals. Wafer connectors consist of fixed-end electrical connectors, namely female contacts (referred to as sockets), and free-end electrical connectors, namely male contacts (referred to as plugs). Its function is to block or isolate the communication bridge between circuits, so that current can flow, so that the circuit can achieve the desired effect and ensure the normal operation of the circuit. Wafer connectors are an important part of electronic equipment and are widely used in electrical, server, computer and other fields.

[0003] It is not well used in scenarios with huge amounts of data to be transmitted. Such scenarios often require higher transmission rates and more channels to meet the data interconnection within the device. Traditional wafer connectors have disadvantages such as excessive transmission loss and excessive internal wiring density.

[0050] In another embodiment, the pin widths of the two plug signal differential pins 132 are equal, and the spacing between the two plug signal differential pins 132 and the plug grounding plate 133 is equal, so that the impedance of signal transmission on the plug signal differential pins 132 is equal, effectively improving the signal transmission rate.

[0051] In another embodiment, the pin width of the plug signal differential pin is 0.36 mm, and the spacing between the plug signal differential pin and the plug grounding plate is 0.45 mm.

[0052] In one embodiment, see Figure 3 The plug signal pin fitting 13 further includes an interference spring piece 1331 connected to the plug grounding plate 133 , and the interference spring piece 1331 is connected to the inner wall of the first mounting through hole 121 by interference fit.

Specifically, one end of the interference spring piece 1331 is connected to the plug grounding piece 133, and the other end of the interference spring piece 1331 is arranged away from the plug grounding piece 133, so that the interference spring piece 1331 is protruded on the plug grounding piece 133, so that the end of the interference spring piece 1331 away from the plug grounding piece 133 abuts against the inner wall of the first mounting through hole 121, realizing the interference connection between the interference spring piece 1331 and the inner wall of the first mounting through hole 121, and then forming an interference fit between the plug grounding piece 133 and the plug base 10a, effectively improving the connection stability between the plug grounding piece 133 and the plug base 10a, thereby improving the reliability of the plug signal pin fitting 13 on the plug base 10a.

[0053] In one embodiment, see Figure 3 , the number of the first mounting through hole 121 and the plug signal pin fitting 13 are both multiple, each of the plug signal pin fitting 13 is arranged in one of the first mounting through holes 121, wherein the multiple first mounting through holes 121 are parallel to each other and arranged in a staggered manner.

[0063] In this embodiment, the two plug signal differential pins 132 are adjacent to each other, and the plug signal differential pins 132 are also adjacent to the plug grounding plate 133, so that the spacing between the two plug signal differential pins 132 and the spacing between the plug signal differential pins 132 and the plug grounding plate 133 are small, which is convenient for weakening the coupling between the two plug signal differential pins 132, thereby reducing the signal crosstalk between the two plug signal differential pins 132, and effectively improving the reliability and signal transmission rate of signal transmission; corresponding mounting through holes are provided on the plug base 10a and the socket base 20a. When the plug base 10a and the socket base 20a are combined and connected, the plug signal differential pins 132 and the socket signal differential pins 232 can be connected through their respective tails, and the plug grounding plate 133 and the socket grounding plate 233 can be connected, so that the pins and the grounding plates are precisely contacted with each other, which effectively improves the reliability of use.

The hook 237 is an extension of the second mounting base 234, and the material of the hook 237 is the same as that of the second mounting base 234, both of which are plastic. By injection molding the card 2331, the hook 237 is formed on the card 2331, so that the elasticity and strength of the hook 237 are improved. The hook 237 corresponds to the disassembly groove 222. When the second mounting base 234 is installed in the second mounting through hole 221, the hook 237 is clamped in the disassembly groove 222. When the socket signal pin fitting 23 needs to be disassembled, it is only necessary to separate the hook 237 in the disassembly groove 222 from the second mounting base 234 through the second mounting through hole 221. Specifically, the disassembly groove 222 is formed with a positioning step on the inner wall of the second mounting through hole 221.

In this embodiment, the piercing groove 2333 is located on the socket grounding plate 233, and the piercing groove 2333 corresponds to the positioning groove 235 on the second mounting base 234. Specifically, when the socket grounding plate 233 and the second mounting base 234 are injection molded, the positioning groove 235 is injection molded with the inner wall of the piercing groove 2333 as the reference surface, so as to form the positioning groove 235 at the position of the piercing groove 2333, so that the positioning groove 235 is based on the piercing groove 2333 to form a mounting positioning groove for the socket wiring 25. Among them, the slot width of the positioning slot 235 is equal to the slot width of the puncture slot 2333, and the slot width of the puncture slot 2333 is less than or equal to the width of the socket wiring 25.

In this embodiment, the wiring welding spring 2332 is located between the socket grounding plate 233 and the socket wiring 25, and the wiring welding spring 2332 serves as an extension of the socket grounding plate 233. Specifically, the wiring welding spring 2332 and the socket grounding plate 233 are made of the same metal material, which facilitates the electrical connection between the wiring welding spring 2332 and the socket grounding plate 233. The wiring welding spring 2332 is welded to the copper foil layer of the socket wiring 25. For example, the position where the wiring welding spring 2332 is welded to the socket wiring 25 is the bare copper on the copper foil layer of the socket wiring 25. The wiring welding spring 2332 not only supports the socket wiring 25 to lift the socket wiring 25 to a position aligned with the socket signal differential pin 232, but also can achieve electrical connection with the copper foil layer of the socket wiring 25, thereby facilitating the reliable transmission of the ground signal between the socket wiring 25 and the socket grounding plate 233.

In this embodiment, the window hole 2334 is located on the socket grounding plate 233, and the window hole 2334 also corresponds to the welding surface 2311 of the socket signal differential pin 232, so that the impedances on the two socket signal differential pins 232 corresponding to the window hole 2334 are consistent, which effectively improves the transmission rate of differential signals.

The dielectric layer 252 is wrapped around the core wire 251, and plays the role of insulation and electromagnetic isolation. For example, the dielectric layer 252 is an isolation layer formed by weaving tin foil or copper wire and non-woven fabric. The copper foil layer 253 is wrapped on the dielectric layer 252. The copper foil layer 253 serves as a transmission layer for the ground signal of the socket wiring 25.

Part of the sheath 254 is sheathed on the copper foil layer 253, that is, the sheath 254 partially overlaps with the copper foil layer 253, so that part of the copper foil layer 253 is exposed, so as to facilitate the formation of a bare copper part for welding with the wiring welding spring 2332, thereby facilitating the electrical connection between the copper foil layer 253 and the socket grounding plate 233.
