Embodiment Construction

[0011] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0012] The present invention is a high-temperature-resistant small-diameter insulating adapter, comprising an adapter housing 1, a jewel bearing 2, and an adapter sleeve 3; the adapter housing 1 and the adapter sleeve 3 are fixed by glass sintering, The adapter shell 1 and the adapter sleeve 3 are made of iron-cobalt-nickel glass-sealed alloy material, which has a small coefficient of thermal expansion and can effectively avoid cracking of the glass sintered part caused by temperature changes. The outer casing of the transfer sleeve 3 is covered with a high-temperature resistant insulating fiber sleeve 4 to ensure the insulation requirements of the circuit.

[0013] The grade of the iron-cobalt-nickel glass sealing alloy material is 4J29, and the implementation standard is YB / T5231-2006.

[0014] The brand name of the high temper...

Abstract

The invention belongs to the airplane electric connection design technology, and relates to a high-temperature-resistant small-diameter insulating adapter. The high-temperature-resistant small-diameter insulating adapter comprises an adapter shell (1), a jewel bearing (2) and an adapter sleeve (3); the adapter shell (1) and the adapter sleeve (3) are sintered and fixed by glass; the adapter shell(1) and the adapter sleeve (3) adopt an iron-cobalt-nickel glass packaged alloy material; the exterior of the adapter sleeve (3) is sleeved with a high-temperature-resistant insulating fiber sleeve (4), so that the insulating requirement of a circuit can be ensured; and one end of the adapter sleeve (3) is connected with internal wires in an armored heater (6) in a crimped form while the other endis connected with an inner core of an external wire (5) in a crimped form so as to achieve circuit connection.

Description

technical field [0001] The invention belongs to the aircraft electrical connection design technology, and relates to a high-temperature-resistant small-diameter insulating adapter. Background technique [0002] In the heating circuit of products such as pressure receptors and angle of attack sensors, the adapter connecting the armored heater to its power supply circuit is one of the important structures in the heating circuit, which affects the realization of the product heating function and working reliability . [0003] At present, the adapter generally adopts a glue-sealed structure. The special epoxy adhesive used has a maximum temperature resistance of 200°C, and can work at a temperature of 100°C for a long time, but cannot withstand high temperatures above 300°C. At the same time, the adapters with rubber-sealed structures have problems such as aging and cracking during long-term use, which affects product reliability and life. [0004] The development of new produc...
