Technical Field

[0001] This application relates to the field of signal connection, and in particular to an immersion liquid-cooled through-type signal connector. Background Technology

[0002] With the development of communication equipment, the operating speed of electronic devices continues to increase, and the heat generated increases dramatically. Heat dissipation has gradually become a key factor restricting further improvement of equipment performance and stable operation. Immersion liquid cooling technology has emerged as an efficient heat dissipation solution. By directly immersing electronic devices in coolant, it utilizes the high specific heat capacity and good thermal conductivity of coolant to quickly remove the heat generated by the equipment, which helps to reduce energy consumption.

[0003] In immersion liquid cooling systems, connectors are needed to connect cables in order to enable signal transmission between electronic devices. There are several traditional connection methods: one is to connect the cable directly to the device's plug-in hole and transmit the signal through a simple plug-and-play operation; another is to fix it with a slot or elastic clip. The connector is equipped with a slot to insert the cable into the slot, or an elastic clip is used to hold the cable in place.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Example 1 Reference Figures 1 to 3This application discloses an immersion liquid-cooled signal through-type connector, comprising: The housing 1 has several through-holes 13 in its middle section. The upper end of the housing 1 has an annular upper flange 11, and the lower end has an annular lower flange 12. The upper flange 11 surrounds the through-holes 13 to form a first sealing region 3; the lower flange 12 surrounds the through-holes 13 to form a second sealing region 4. The first sealing region 3 and the second sealing region 4 are filled with encapsulating filler 8 to isolate and limit the cable 7 connected to the terminal block 2. Terminal 2, a plurality of terminal 2 are inserted into and fixed in wiring hole 13, and the upper end and lower end of terminal 2 protrude from wiring hole 13.

[0031] Specifically, refer to Figures 1 to 3 The upper end of the housing 1 is provided with an upper flange 11, which surrounds the upper insertion hole 21 to form a first sealing area 3. The upper flange 11 is generally integrally formed with the housing 1 and is made of the same material as the housing 1, usually plastic or metal. The height of the upper flange 11 is moderate, which can effectively surround the upper insertion hole 21 without taking up too much space. The edges of the upper flange 11 can be chamfered to avoid scratching the operator. The first sealing area 3 is filled with glue after the cable 7 is connected. The glue can be epoxy resin, which has good sealing and corrosion resistance. The lower end of the housing 1 is provided with a lower flange 12, which surrounds the lower insertion hole 22. Inside, a second sealing area 4 is formed; the structure and function of the lower flange 12 are similar to those of the upper flange 11, also serving to seal, isolate the cable 7, and provide protection; the lower flange 12 and the upper flange 11 are arranged opposite to each other to ensure the sealing performance of the connector; the second sealing area 4 is also filled with glue after the cable 7 is connected to further enhance the sealing effect; in addition, the glue filled in the first sealing area 3 and the second sealing area 4 can effectively fix the position of the cable 7 and prevent the cable 7 from interfering in the liquid and affecting signal transmission; symmetrical reinforcing ribs 142 are arranged on the side wall of the housing 1, which can enhance the structural strength of the connector.

[0032] Reference Figures 2 to 4Terminal blocks 2 are evenly distributed throughout the middle of the housing 1 to achieve orderly connection of multiple cables 7. Terminal blocks 2 are usually made of metal materials, such as copper alloy, which have good conductivity. Terminal blocks 2 can also be made of aluminum alloy, which is lightweight and has a certain conductivity. Cables 7 are connected to the upper insertion hole 21 and the lower insertion hole 22 of terminal blocks 2 to transmit signals. The inner walls of the upper insertion hole 21 and the lower insertion hole 22 of terminal blocks 2 are usually smoothed to reduce wear on the cables 7. The housing 1 has a wiring hole 13 in the middle that is adapted to the terminal 2. The inner wall of the wiring hole 13 is smooth, which facilitates the insertion of the terminal 2. The wiring hole 13 is adapted to the terminal 2 to ensure the stability of the connection. The terminal 2 is fitted with a snap-fit ​​23 in the middle to prevent the terminal 2 from falling off. The snap-fit ​​23 is a circular tubular structure. The snap-fit ​​23 is generally made of plastic and has a certain degree of elasticity. The snap-fit ​​23 can also be made of rubber, which has better elasticity. The housing 1 is provided with a first sealing gasket 5 and a second sealing gasket 6. The first sealing gasket 5 is located at the root of the first sealing area 3 and is used to seal the gap between the terminal 2 and the housing 1. The first sealing gasket 5 is usually made of rubber and has good elasticity and sealing performance. The first sealing gasket 5 can also be made of silicone, which has good high and low temperature resistance. The first sealing gasket 5 has a positioning protrusion 51 on its side wall, and the upper flange portion 11 has a positioning groove 111 on its side wall that matches the positioning protrusion 51. The positioning protrusion 51 and the positioning groove 111 can ensure that the first sealing gasket 5 is accurately installed. The second sealing gasket 6 is located on the upper surface of the housing 1 and is used to seal the gap between the housing 1 and the carrier 9. The structure and material of the second sealing gasket 6 are similar to those of the first sealing gasket 5, and it also plays a sealing role. The size of the second sealing gasket 6 is designed according to the contact area between the housing 1 and the immersion box.

[0033] Reference Figures 4 to 5 The side wall of the wiring hole 13 is provided with a positioning protrusion 131 that limits the installation position of the wiring terminal 2; the wiring terminal 2 is provided with a positioning shoulder 25 that matches the positioning protrusion 131; a snap-fit ​​member 23 for preventing the wiring terminal 2 from falling off is sleeved in the middle of the wiring terminal 2, and the side wall of the wiring terminal 2 is provided with a receiving groove 24 for installing the snap-fit ​​member 23. The depth and width of the receiving groove 24 match the snap-fit ​​member 23, and the snap-fit ​​member 23 can be firmly sleeved in the receiving groove 24.

[0034] Reference Figures 4 to 5The snap-fit ​​component 23 has a circular tubular structure with an elastic opening groove 232 on its side wall. The snap-fit ​​component 23 has an elastic clip 231 circumferentially positioned to abut against the positioning protrusion ring 131. The positioning protrusion ring 131 is located between the elastic clip 231 and the positioning shoulder 25. The elastic clip 231 can be triangular, rectangular, or other shapes, effectively securing the terminal 2. The side wall of the wiring hole 13 has a positioning protrusion ring 131 that abuts against the elastic clip 231. The positioning protrusion ring 131 further secures the terminal 2, preventing it from moving up and down. The snap-fit ​​component 23 has an elastic opening groove 232 on its side wall, which facilitates the installation and removal of the snap-fit ​​component 23. The elastic opening groove 232 can be rectangular. During installation and removal, the elastic opening groove 232 undergoes elastic deformation, allowing the snap-fit ​​component 23 to snap onto the terminal 2.

[0035] Reference Figures 4 to 5 The encapsulation filler 8 can be made of silicone, which has good elasticity and sealing performance and can adapt to different temperature changes; or it can be made of epoxy resin, which has high hardness and corrosion resistance. After the encapsulation filler 8 is filled in the sealing area, it can tightly wrap the connection part between the connecting wire and the terminal 2, prevent coolant from entering, and restrict the movement of the connecting wire, ensuring the stability of the connection and effectively reducing the risk of interference of the cable 7 in the liquid and affecting signal transmission.

[0036] The implementation principle of this embodiment is as follows: the immersion liquid-cooled signal through connector uses the encapsulation filler 8 to fix the cable 7 individually, avoiding multiple cables 7 from sharing the channel. In conjunction with the first sealing area 3 and the second sealing area 4, it prevents the cables 7 from tangling and interfering with each other in the liquid-cooled environment. The first sealing gasket 5 and the second sealing gasket 6 seal the connector, further improving the sealing effect of the connector.
