Description

TECHNICAL FIELD

[0001] The utility model relates to the field of connector, concretely relates to a miniaturized high temperature corrosion -resistant sealed connector socket. BACKGROUND

[0002] The aircraft engine is the core power device of the aircraft and is praised as the "heart" of the aircraft. The connector is an essential component of the aircraft engine, and with the continuous development of the aviation field, the use conditions are gradually harsh. The connector must have comprehensive characteristics such as high strength, temperature resistance, corrosion resistance, and sealing. Considering the weight limit of the aircraft, the connector also needs to have the characteristics of miniaturization and light weight. This special working environment poses extremely harsh challenges to the design, processing and manufacturing capacity of the connector. For example Figure 1 The conventional connector shown in the drawing is difficult to have all the characteristics while ensuring reliability, so that the connector for the aircraft engine is limited. INNOVATION CONTENT

[0003] The utility model aims at improving the structure of the existing connector, and realizes the miniaturization, high strength, temperature resistance, corrosion resistance, sealing and other comprehensive characteristics of the connector through improvement.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A miniaturized high temperature corrosion -resistant sealed connector socket, including casing, pin and the mounting plate of fixed pin, the casing, pin, mounting plate three are encapsulated integrated molding.

[0006] In the above technical scheme, the mounting plate is a ceramic insulator, and the pin and the ceramic insulator are integrally encapsulated and formed.

[0007] In the above technical scheme, the mounting plate is a ceramic insulator, and the ceramic insulator and the casing are integrally encapsulated and formed.

[0008] In the above technical scheme, the pin surface is smooth, and the pin directly contacts the mounting plate.

[0009] In the above technical scheme, no other structure is arranged between the pin and the mounting plate.

[0010] In the above technical scheme, the casing is provided with a sealing groove, and the sealing groove is provided with a sealing element.

[0011] In summary, due to the adoption of the above technical scheme, the utility model has the beneficial effects that:

[0012] This solution utilizes a ceramic sealing process to seal and connect the pin core, ceramic insulation board, and shell into a single unit. Ceramic possesses excellent insulation and high-temperature resistance, effectively ensuring electrical insulation between pin cores and between the pin core and the shell, while also withstanding temperature shocks of 300℃ or even higher. The shell is made of stainless steel, meeting strength and corrosion resistance requirements under extreme conditions. The ceramic-sealed pin core forms a socket assembly, creating an effective seal between the pin core and the ceramic, and between the ceramic and the shell, capable of withstanding hydrostatic pressures exceeding 10MPa, meeting the product's sealing requirements. The pin core, ceramic insulator, and shell are fixed in position using a sealing mold, eliminating the need for additional assembly positioning structures during assembly, maximizing the simplification of the three components' design and reducing processing requirements. This reduction in connector size enables miniaturization and weight reduction. Attached Figure Description

[0018] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0019] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0020] like Figure 2 and Figure 3 As shown, the socket in this embodiment includes a housing 4, and a mounting plate 2 made of ceramic insulator is disposed inside the housing 4. A pin 1 is disposed inside the mounting plate 2.

[0021] In this embodiment, the mounting plate 2 and the pin 1 of the ceramic insulator are integrally formed, directly encapsulating them as one unit. This eliminates the need for additional positioning and locking structures between the pin 1 and the mounting plate 2, allowing the pin 1 to be designed with a smooth surface for direct contact with the ceramic insulator. Consequently, the mounting plate 2 possesses excellent insulation and corrosion resistance, and can withstand temperature shocks of 300°C or even higher.

[0022] In this embodiment, the mounting plate 2 of the ceramic insulator and the housing 4 are integrally sealed and formed. The housing 4 is made of stainless steel. The socket assembly is formed by encapsulating the pin 1 with the ceramic insulator. This can achieve an effective seal between the housing 4, the mounting plate 2, and the pin 1, and can withstand hydrostatic pressure of more than 10MPa.

[0023] When assembling the three parts, housing 4, mounting plate 2, and pin 1, there is no need to design an assembly positioning structure. This simplifies the design structure of the three parts to the greatest extent, reduces the processing requirements of the parts, and reduces the size of the connector, thus enabling the connector to be miniaturized and lightweight.

[0024] like Figure 3 As shown, the socket is installed on the housing 7. A groove is provided on the end face of the socket housing 4, and a sealing ring 3 is provided in the groove. The housing 4 is fixed to the housing 7 by screws 6. The insulating oil 5 inside the housing 7 cannot flow out of the socket through the ceramic insulator, and the insulating oil 5 cannot corrode the ceramic insulator, thus achieving corrosion resistance and insulation performance under high temperature environment.

[0025] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
