Problems solved by technology

Although this type of connector realizes the pull-off separation of the electrical interface, the spring claws of the locking sleeve open and the threaded sleeve is displaced due to pull-off, which cannot be reset. It is used once and has a small scope of application.

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] figure 1 As shown, a pull-off electrical connector based on the aviation auxiliary fuel tank system includes a cable cover shell 1, a shielding sleeve 2, a shielding layer 3, an O-ring 4, a seat shell 5, a hole core assembly 6, and a head shell 7 , needle core assembly 8, clamp 10, threaded inner sleeve 11, connecting nut 12, wave ring 13, circular ratchet bar 14, ratchet wheel 15, pull hoop 16, stainless steel pull rope 17, heat shrinkable sleeve 18 and hollow tube 19 . The needle core assembly 8 and the hole core assembly 6 are inserted into each other and are respectively arranged in the head shell 7 and the seat shell 5. One end of the head shell 7 is inserted into one end of the seat shell 5 correspondingly, and one end of the head shell 7 is connected to the other end. The connecting nut 12 and the pull hoop 16 are sequentially slidably s...

Abstract

A pull-off electrical connector based on an aviation auxiliary fuel tank system. The pull-off electrical connector comprises a head shell (7), a seat shell (5), a hole core assembly (6) and a pin core assembly (8), wherein the pin core assembly (8) and the hole core assembly (6) are inserted into each other, and are respectively arranged in the head shell (7) and the seat shell (5); and one end of the head shell (7) is correspondingly plugged in one end of the seat shell (5), and an external auxiliary fuel tank is rapidly stripped from a fuselage by elastically restraining the connection between the head shell (7) and the seat shell (5). By cooperating with a connecting mechanism of an elastic reset electrical connector and a design of reducing weight and resisting elctromagnetic interference using a composite material, the present invention has a compact and stable overall structure, is secure and reliable in pull-off separation and is suitable for a fuel system with an aviation auxiliary fuel tank.

Description

technical field [0001] The invention relates to an electrical connector, in particular to a pull-off electrical connector based on an aviation auxiliary fuel tank system. Background technique [0002] Modern aviation technology is changing with each passing day. Lightweight, anti-electromagnetic environment, stealth, flight safety, etc. have become the research directions of current aviation technology development. The auxiliary fuel tank fuel system is one of the subsystems with the largest dead weight in the aircraft, and it also plays a vital role in the flight distance and combat radius. The traditional auxiliary fuel tank and its auxiliary electrical interface are generally made of stainless steel due to the consideration of stress intensity, and the dead weight and radar wave reflection surface are relatively large. In addition, most of the auxiliary fuel tanks are thrown away using electric detonation separation technology, which will cause great damage to the electr...
