Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sealing bases, and more specifically, the utility model relates to an anti-blocking glass encapsulation sealing base. Background Art
[0002] The glass encapsulation sealing base is a packaging technology that uses glass materials to isolate electronic components from the external environment. The glass encapsulation sealing base is mainly applied in the fields of electronics, optical communication, and new energy, etc., and is a key component for protecting and extending the product life. Its manufacturing involves high-precision and technology-intensive processes, including the matching sealing and sintering of metal components, etc., and plays an irreplaceable role in protecting key electronic and optoelectronic components. With the continuous progress of technology and the diversification of market demands, the glass encapsulation technology is also constantly evolving to meet more complex and stringent application conditions.
[0003] After the sealing base is filled with oil, it is necessary to maintain a good sealing state to prevent leakage. The existing sealing bases usually use a single plug for dynamic sealing, and the structure is relatively simple. However, after long-term sealing by the plug, the surface is likely to become smooth, thereby reducing the sealing effect and shortening the sealing duration of the sealing base. Summary of the Utility Model
[0004] In order to overcome the deficiencies of the prior art, the utility model provides an anti-blocking glass encapsulation sealing base, which has the advantage of more precise operation.
[0005] To achieve the above object, the utility model provides the following technical solution: an anti-blocking glass encapsulation sealing base, comprising: a base body, a first seal and a second seal; first chambers and second chambers are respectively formed on both sides of the base body, an oil filling hole is formed inside the first chamber, the oil filling hole penetrates through the base body, and one end of the oil filling hole away from the first chamber extends into the second chamber. A connecting piece is arranged at one end of the oil filling hole close to the first chamber, a plug is connected inside the connecting piece, the plug extends into the oil filling hole, a glass insulator is arranged inside the base body, and a lead is arranged inside the glass insulator; both the first seal and the second seal are arranged in the oil filling hole, an elastic member is connected between the first seal and the second seal, grooves are formed on the inner walls of both the first seal and the second seal, gaskets are arranged inside the grooves, the plug is arranged inside the first seal and the second seal, the gaskets are respectively in contact with the plug, and one end of the plug close to the second chamber is engaged with the second seal.
[0006] As a preferred technical solution of the present utility model, the connecting member is of an annular plate structure, threads are processed on the inner wall of the connecting member and the outer wall of the plug, and a pull ring is connected to one end of the plug away from the oil filling hole; this improves the connection stability between the plug and the oil filling hole and facilitates people to take the plug.
[0007] As a preferred technical solution of the present utility model, through holes are provided on both the first sealing member and the second sealing member, and the plug is arranged inside the through holes; this enriches the structure inside the oil filling hole and enhances the sealing performance.
[0008] As a preferred technical solution of the present utility model, a diversion member is fixed to one end of the second sealing member away from the elastic member, and the diversion member extends into the second chamber; this prevents oil from splashing onto the inner wall of the oil filling hole during oil injection.
[0009] As a preferred technical solution of the present utility model, a support member is fixed to the inner wall of the first chamber. The cross-section of one end of the support member close to the lead is "U"-shaped, and the lead is in contact with one end of the support member; this prevents the lead from collapsing.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: By arranging the first sealing member and the second sealing member in the oil filling hole, the structure inside the oil filling hole can be enriched, making the sealing structures closer to each other. A diversion member is arranged on one side of the second sealing member, and the elastic member arranged between the first sealing member and the second sealing member can control the distance between the second sealing member and the first sealing member. When the plug is not connected to the oil filling hole, it is convenient for people to align the oil injection device with the diversion member, which can guide people to directly inject oil into the second chamber during oil injection, preventing it from splashing onto the inner wall of the oil filling hole, keeping the side of the plug dry, preventing the sealing effect from being reduced after the plug comes into contact with oil, increasing the sealing structure inside the oil filling hole, and improving the sealing performance of the base body through multiple cooperations.

[0018] Among them, the connecting piece 3 is of an annular plate structure, threads are processed on the inner wall of the connecting piece 3 and the outer wall of the plug 4, and a pull ring 6 is connected to one end of the plug 4 away from the oil filling hole 8; improving the connection stability between the plug 4 and the oil filling hole 8 and facilitating people to take the plug 4.
[0019] Among them, through holes are opened on both the first seal 9 and the second seal 10, and the plug 4 is arranged inside the through holes; filling the structure inside the oil filling hole 8 and enhancing the sealing performance.
[0020] Wherein, a flow guide member 14 is fixed to one end of the second seal member 10 away from the elastic member 12, and the flow guide member 14 extends into the second chamber 15; this prevents oil from spilling onto the inner wall of the oil filling hole 8 when injecting oil.
