Description

Technical Field

[0001] The utility model relates to the field of connector sealing structures, in particular to a high-pressure resistant glass sealing connector structure. Background Art

[0002] As one of the key components for transmitting current or signals, the size of the connector is generally affected by the size or structure of the supporting components and cannot be made too large. For applications with high power transmission, the distance between the lead and the shell of the ordinary structure of the glass insulator is limited and cannot carry too high a voltage. In a high-humidity environment, the voltage resistance and insulation strength will decrease, causing breakdown, damaging the connector or causing damage to the equipment. Utility Model Content

[0003] The utility model provides a high-pressure resistant glass sealing connector structure, which can solve the problems pointed out in the background technology.

[0004] A high-voltage resistant glass sealed connector structure comprises a glass insulator, an isolating piece sintered on the glass insulator, and a lead wire, wherein the isolating piece separates the glass insulator into two parts, an inner ring and an outer ring, and the lead wire is located in the inner ring part.

[0005] Preferably, the isolation element is a hollow cylindrical structure.

[0006] Preferably, at least one end of the isolation member exceeds the plane where the end surface of the glass insulator is located.

[0007] Preferably, the isolating element is made of ceramic.

[0008] Preferably, the length of the spacer extending beyond the glass insulator is at least 1 mm.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] Compared with the prior art, the utility model sintered a spacer in the middle of the glass insulator, and the upper and lower ends of the spacer were higher than the glass sealing plane, so that the glass insulator was divided into two parts, the inner ring and the outer ring. The spacer played a role in increasing the creepage distance, and could increase the voltage resistance of the connector by 2 to 3 times without increasing or slightly increasing the glass sealing distance; at the same time, it could resist short circuits caused by the environment or pollution, and effectively protect the connector and the equipment. This technology can greatly improve the performance and reliability of the product, extend the service life, and protect the safety of equipment use. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0016] like Figure 1 As shown, the distance between the lead 3 and the housing 4 of the glass-sealed connector in the prior art is small, and breakdown is prone to occur under high voltage conditions. Due to the size limitation of the installation holes of the existing supporting components, it is impossible to increase the creepage distance by increasing the area of ​​the glass insulator. Based on this, the following glass-sealed ceramic isolation wall technology has been developed;

[0017] like Figure 2 As shown, a high-pressure resistant glass sealed connector structure provided by an embodiment of the utility model comprises a glass insulator 1, an isolating member 2 sintered on the glass insulator 1, and a lead 3;

[0018] Preferably, the isolator 2 of this embodiment is a hollow cylindrical structure made of ceramic material (specifically, a cylindrical structure, a square cylindrical structure or a polygonal cylindrical structure can be selected according to actual conditions), which separates the glass insulator 1 into an inner ring and an outer ring, and the lead 3 is located in the inner ring part;

[0019] At least one end of the spacer 2 exceeds the plane where the end surface of the glass insulator 1 is located. Figure 2 As shown, in this embodiment, both ends of the best effect are beyond the plane where the end surface of the glass insulator 1 is located;

[0020] Specifically, the length of the isolating member 2 exceeding the glass insulator 1 is at least 1 mm, or the total length of the isolating member 2 is at least 1.1 times the thickness of the glass insulator. In specific use, technicians in this field can make a choice based on actual conditions, but should choose the smaller of the two methods mentioned above. Of course, the overall length of the isolation room 2 cannot be infinitely long, and a suitable length should be selected based on the actual installation space.

[0021] The isolator 2 serves to increase the creepage distance, and can improve the voltage resistance performance of the connector by 2 to 3 times without increasing or slightly increasing the glass sealing distance (area of ​​the glass insulator 1); at the same time, it can resist short circuits caused by the environment or pollution, and effectively protect the connector and equipment; this technology can greatly improve the performance and reliability of the product, extend its service life, and protect the safety of equipment use.

[0022] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit and basic features of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim involved.

[0023] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
