Embodiment 1

[0030] see Figure 1-4 As shown, a titanium alloy sealed connector includes a titanium alloy shell 1 made of TC4 titanium alloy, a first glass blank 3 made of BH-G / K glass, a second glass blank 5 and a third glass blank The blank 203 and the inner housing 201 made of Kovar alloy, the first contact pin 4 and the second contact pin 202, the inner housing 201, the second contact pin 202 and the third glass blank 203 are assembled into a joint assembly 2, the second The second pin 202 is installed inside the inner shell 201, the third glass blank 203 is installed between the second pin 202 and the inner shell 201, and the inner center of the titanium alloy shell 1 is provided with a number of uniformly distributed first sinks. hole 101 and the second counterbore 102, the joint assembly 2 is located inside the first counterbore 101, the first glass blank 3 is arranged between the joint assembly 2 and the first counterbore 101, and the first pin 4 is located in the second counterbor...

Embodiment 2

[0034] The titanium alloy sealed connector with the structure of Example 1 is manufactured according to the following steps:

[0035]Step S1, using clear water as the grinding liquid, and polishing the inner surfaces of the first counterbore 101 and the second counterbore 102 with aluminum oxide waterproof sandpaper, so that the inner surfaces of the first counterbore 101 and the second counterbore 102 are rough The thickness is 1.6 μm, and then electrochemically polish the titanium alloy shell 1 as a whole, and use nitrogen gas to dry it for later use; put the inner shell 201, the first pin 4 and the second pin 202 at 1000°C, hydrogen Purify in the atmosphere for 1h, then at 550℃, N 2 / 2%H 2 Oxidation treatment in O binary atmosphere for 5 minutes, cooled for later use;

[0036] Step S2: All the titanium alloy casing 1, the inner casing 201, the first pin 4, the second pin 202, the first glass blank 3, the second glass blank 5, and the third glass blank 203 processed in ste...

Embodiment 3

[0041] The titanium alloy sealed connector with the structure of Example 1 is manufactured according to the following steps:

[0042] Step S1, using clear water as the grinding liquid, and polishing the inner surfaces of the first counterbore 101 and the second counterbore 102 with aluminum oxide waterproof sandpaper, so that the inner surfaces of the first counterbore 101 and the second counterbore 102 are rough The thickness is 0.8 μm, and then electrochemically polish the titanium alloy shell 1 as a whole, and use nitrogen gas to dry it for later use; put the inner shell 201, the first pin 4 and the second pin 202 at 1000°C, hydrogen Purify in the atmosphere for 1h, then at 550℃, N 2 / 2%H 2 Oxidation treatment in a binary atmosphere for 8 minutes, cooled for later use;

Abstract

The invention relates to a titanium alloy hermetically sealed connector and a production process thereof, and belongs to the technical field of hermetically sealed connectors. The titanium alloy hermetically sealed connector comprises a titanium alloy shell, a joint assembly and a first pin, wherein a first counter bore and a second counter bore are formed in the center of the interior of the titanium alloy shell, the joint assembly is located in the first counter bore, a first glass blank is arranged between the joint assembly and the first counter bore, the first contact pin is located in the second counter bore, and a second glass blank is arranged between the first contact pin and the second counter bore. The production process comprises the steps of S1, part pretreatment, S2, part cleaning, S3, die filling and sintering, and S4, bonding and detection. Compared with a straight-through hole in an existing product, the first counter bore and the second counter bore are formed, so that the contact area between the glass blank and the titanium alloy shell can be increased, and the sealing reliability is improved; and a bonding layer is formed through electrifying heat preservation treatment before detection, further tight connection of the glass blank and the titanium alloy shell is achieved, and the sealing effect of the titanium alloy hermetically sealed connector is improved.

Description

technical field [0001] The invention belongs to the technical field of sealed connectors, and in particular relates to a titanium alloy sealed connector and a production process thereof. Background technique [0002] Titanium and its alloys have good mechanical properties, as well as excellent oxidation resistance and corrosion resistance; glass materials have the advantages of good optical transparency, high hardness, high thermal stability and good electrical insulation. Glass and titanium alloys The connectors made by connecting have been widely used in technical fields such as micro-electromechanical systems and aerospace engineering; and in the field of connectors, the housing of the connector with the best sealing performance and the contacts set in the inner hole of the housing are through Sintered glass is sealed together, but the current sealing effect of titanium alloy glass sealing technology is not good, and it cannot meet the airtightness requirements under high...
