Embodiment Construction

[0019] Examples of flameproof short-circuit electrical connectors, such as Figure 2-5 As shown, including housing parts and contact parts.

[0020] The housing part includes an outer shell part 11 , a front insulator 12 , a rear insulator 13 and a pressure plate 14 . In this embodiment, the outer casing 11 is a rectangular metal piece, which has two mounting holes through the front and rear and a connecting hole between the two mounting holes, wherein the connecting hole is a counterbore with a small front and a large rear, and a connecting hole at the rear. The insulator 13 has a sleeve portion corresponding to the above-mentioned mounting hole and a plate-shaped stop portion located at the rear end of the sleeve portion, and the sleeve portion is inserted into the corresponding mounting hole. The rear end of the front insulator 12 is provided with a concave stop. Correspondingly, the rear insulator 13 is provided with a convex stop corresponding to the concave stop. The fr...

Abstract

The invention relates to the field of electrical connectors, in particular to a fireproof short-circuit electrical connector. The electrical connector comprises a shell component, more than two contact components are assembled in the shell component, each contact component comprises a contactor and a tail contact assembled in the shell component in tandem, a floating spring is mounted at the rear end of each contactor, each contactor in the initial state is in open-circuit with the corresponding tail contact, and shifting blocks used for shifting the contactors rearwards to enable the contactors to retract into corresponding mounting holes are further arranged on the shell component. When an aircraft is launched, each contactor and the corresponding tail contact are in open circuit, and short circuit of corresponding equipment cannot be caused; when the aircraft is assembled, the shifting blocks are shifted to enable the contactors to retract into the shell component so as to prevent the contactors from being damaged; after the aircraft is assembled, the shifting blocks are released. Thus, by the fireproof short-circuit electrical connector, the problem that contactors of an existing short-circuit electrical connector are in short circuit accidentally easily and damaged by the aircraft easily is solved.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a fireproof short-circuit electrical connector. Background technique [0002] With the continuous integration and modularization of electrical equipment, electrical connectors have been more and more widely used in communications, electric power, aerospace and other fields. In most cases, electrical connectors are used to connect and disconnect circuits. However, in some special occasions, the electrical connector is also required to have some other functions, such as the launcher of an aircraft powered by fuel combustion, and the electrical connector used requires that the contacts between the contacts be connected to the aircraft after they are plugged into the aircraft. The electrical connectors that rely on the mutual short circuit between the contacts are generally called short-circuit electrical connectors to provide detection signals to the aircraft.
