[0002] A connector is a device or interface used to connect, disconnect, and transmit signals and power. It usually consists of two or more connector plugs and corresponding connector sockets. Connectors can be used in a variety of devices and scenarios, such as electronic devices, computer networks, communication equipment, automobiles, aerospace, etc. They may have different sizes, shapes, pin counts, and transmission characteristics in different applications to meet different needs. In short, the connector is an important electronic component used to realize signal and power transmission between devices, with the functions of connection and disconnection, signal transmission, and power transmission. It plays a key role in various applications.

In addition, the voltage tolerance of current connectors is generally at the level of hundreds of volts to thousands of volts. At higher voltage levels, they may burn out (insulation between connecting pins is insufficient, and arc discharge will occur due to excessive voltage). Serious safety accidents may occur.

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0038] Example 1

[0039] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0040] Please refer to Figures 1 to 3 As shown, an embodiment of the utility model provides a high-pressure resistant airtight connector, which includes: an insulating mounting plate 2 made of ceramic material, on which at least one mounting hole 4 is provided, and a pin 1 is passed through the mounting hole 4, and both ends of the pin 1 protrude from the two ends of the insulating mounting plate 2; the mounting hole 4 includes an annular groove 5 formed around the pin 1 at both ends; the annular groove 5 has a metallized surface not higher than the notch; one end of the pin 1 is used to be plugged into the jack component 3; the pin 1 is filled with solder at least in the annular groove 5 connected to one end of the jack component 3, and the filled solder does not exceed the metallized surface, wherein the melting point of the solder is not less than 300°C.

[0041] In the above embodiment, by adopting the insulating mounting plate 2 and the pin 1 structure made of ceramic material, the performance deficiency and potential safety hazard of the traditional connector under high-voltage environment can be effectively solved; specifically, the insulating mounting plate 2 made of ceramic material has high insulation performance, can effectively isolate high-voltage current, and reduce the occurrence of arc discharge; compared with plastic packaging, the ceramic material can better withstand the requirements of high temperature and high voltage environment, and provides more reliable insulation protection. Secondly, the two ends of the connector pin 1 protrude from the two ends of the insulating mounting plate 2, and an annular groove 2 is provided in the mounting hole; the high-pressure airtight connector structure forms an airtight connection between the pin 1 and the insulating material, effectively preventing leakage and breakdown under high-voltage conditions; in addition, one end of the pin 1 is also filled with solder, which further enhances the stability and sealing of the connection.

[0042] The ceramic insulating mounting plate 2 and the airtight connection structure enable the connector to withstand higher voltages and improve the voltage resistance performance. Compared with traditional connectors, it can handle higher voltage levels and avoid failures and safety accidents caused by arc discharge. In addition, the ceramic material has good thermal conductivity, and its thermal conductivity coefficient is 14-25W·m -1 ·K -1 , which is equivalent to 5 to 10 times the thermal conductivity of ordinary heat dissipation silicone grease, can effectively dissipate heat and reduce the impact of heat generation on the connector, so that the connector can better maintain stability and reliability during long-term use; by filling solder in the annular groove 5 and metallizing the surface of the annular groove 5, the solder can be better and more stably attached to the surface of the annular groove 5, so that the connector has better stability and sealing, can effectively prevent gas and liquid leakage, and reduce contact resistance, thereby improving connection reliability.

[0043] Example 2

[0044] The embodiment of the utility model provides a high-pressure resistant air-tight connector, wherein the insulating mounting plate 2 is made of A95 ceramic material, wherein the A95 ceramic material is 95% alumina ceramic (aluminum oxide).

[0045] It should be noted that A95 ceramic material is a high-purity alumina ceramic material. The bending strength, compressive strength and tensile strength of A95 ceramic material are very high, far exceeding other materials such as plastics and metals. Because A95 ceramic material has the characteristics of very high hardness, it can show excellent wear resistance in high-speed movement or friction environments. More importantly, A95 ceramic material has very high high temperature resistance and can operate stably for a long time in high temperature environments without being affected by problems such as thermal expansion, so that high-pressure air-tight connectors can work to support high temperatures caused by high voltages. A95 ceramic material has good insulation properties and can effectively isolate current to avoid safety issues such as electric shock. Because it can resist the erosion of chemical substances such as acids and alkalis and is not easily affected by chemical corrosion, it can be used in application scenarios in harsh environments.

[0046] In one embodiment of the present application, the pin 1 is made of copper alloy and has a gold-plated layer on the surface, wherein the gold-plated layer is gold element and has a thickness of 1.27 μm; for example, the diameter of the pin 1 is 1 mm-2 mm, and the insulating mounting plate 2 is about 7 mm made of A95 ceramic material, and the distance between the mounting holes 4 is set to 3 mm-6 mm, so that the high-voltage airtight connector can support a withstand voltage value of up to 50,000 volts.

[0047] In one embodiment of the present application, two fixing through holes 6 are provided on the outer edge of the insulating mounting plate 2 made of ceramic material, which are used to fix the high-pressure airtight connector to the target for easy installation and use.

[0048] In one embodiment of the present application, refer to Fig.12 As shown, one outer corner of the insulating mounting plate 2 is missing, and the missing corner can be used to prevent mistakes and identify orientation, especially when the connector is directional, to prevent plugging errors.

[0049] Example 3

[0050] The utility model embodiment provides a high pressure resistant airtight connector, referring to Figures 9 to 12 As shown, the insulating mounting plate 2 is provided with 12 mounting holes 4 arranged in two rows, and each mounting hole is provided with a pin 1, wherein the above-mentioned high-pressure resistant air-tight connector can be customized according to the user with different numbers of pins 1, which can be from 2 to 10 pins or 12 pins and other types.

[0051] In one embodiment of the present application, refer to Figures 4 to 7As shown, the jack assembly 3 includes: a connecting needle 31 and a sheath 32; the connecting needle 31 includes a first end 311, a middle end 312 and a second end 313 connected in sequence; the second end 313 has at least two spring pieces, wherein the pin 1 is inserted into the space formed between the spring pieces; the sheath 32 is covered on the outside of the second end 313.

[0052] Through the above structure, the design of adding the sheath 32 can better protect the structure of the connecting pin 31, and effectively prevent the connecting pin 31 from being damaged by external impact or wear; the use of a spring-type design at the second end 313 of the connecting pin 31 can make the pin 1 inserted in the space formed between the springs, thereby increasing the contact area between the pin 1 and the connecting pin 31, improving the stability of the connection, and can also effectively fix the pin 1 to prevent the pin 1 from loosening or losing connection due to factors such as vibration, thereby improving the reliability of the connection; the sheath 32 can reduce the loss of the connecting pin 31 during long-term use, thereby extending the service life of the jack assembly 3.

[0053] In one embodiment of the present application, refer to Figure 8 As shown, the insertion pin 1 includes a needle tail 11, a protrusion 12 and a needle head 13 which are integrally arranged; the diameter of the protrusion 12 is larger than the diameters of the needle tail 11 and the needle head 13; and the needle tail 11 is located in the mounting hole 4.

[0054] The protrusion 12 set between the needle head 13 and the needle tail 11 plays a limiting role when the needle head 13 is inserted into the socket assembly 3, preventing damage to the pin 1 and the socket assembly 3 due to excessive insertion, and effectively protecting the pin 1 and the socket assembly 3.
