Problems solved by technology

[0003] After investigating the existing separation and separation electrical connectors in China, for short-circuit proof plug connectors, there are already plug connectors with double-layer insulator components, which are used to adapt to sockets with double-layer insulator components; and for some There is no corresponding anti-short-circuit plug electrical connector for sockets with three-layer insulator components used in the occasion. After analysis, when the plug with double-layer insulator components is used to adapt the socket connector with three-layer insulator components , there are problems such as changes in axial dimensions,

Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0021] A short-circuit-proof separation plug connector with a three-layer insulator assembly is adopted, in which the front layer is the same size as the original plug to ensure interchangeable docking with the socket; the back layer is a welding wire layer for docking with user cables; the middle layer The movable layer follows the movement of the connecting mechanism, the pinholes of the three layers are connected when they are plugged in, and the pinholes of the three layers are disconnected when they are separated, so as to realize the function of preventing short circuit in the separated state.

[0022] Such as figure 1 Shown is a schematic diagram of the structure of the anti-short-circuit separation plug connector. It can be seen from the figure that a short-circuit-proof separation plug connector with a three-layer insulator assembly inc...

Abstract

The invention discloses a short-circuit-proof separable plug connector with a three-layer insulator assembly, and relates to the technical field of aerospace electrical connectors. The short circuit-proof separable plug connector comprises a nylon wire, a plug dust cover, a pin hole, a conductive rubber ring, a connecting rod, a plug cable cover, a connecting mechanism and a plug housing. The plugdust cover is fixedly mounted on one axial end of the plug housing. The plug cable cover is fixedly mounted on the other axial end of the plug housing. The connecting mechanism is fixedly mounted onthe axis of the plug cable cover and extends into the plug housing. The nylon wire is wound around the one axial end of the plug dust cover. The pin hole is arranged inside the plug housing and located under the connecting mechanism. The conductive rubber ring is fixedly mounted on the outer wall of a front surface layer. The short-circuit-proof separable plug connector in the invention meets thepurpose of adaptation to a socket electrical connector with a three-layer insulator assembly used in certain situations, and the plug connector has the function of preventing a short circuit after theelectrical connector is separated and the signal of the socket and plug is disconnected.

Description

technical field [0001] The invention relates to the technical field of aerospace electrical connectors, in particular to a short-circuit-proof separation plug connector with a three-layer insulator assembly. Background technique [0002] Separation and fall-off electrical connectors are widely used in the field of aerospace where electrical connections are required. In general, when the electrical connector is separated, since the signal has been disconnected, the plug connector does not need to be short-circuit proof, but in some special occasions, such as the plug connector end is connected to some precision instruments that still need to work , the plug electrical connector needs to have a short-circuit proof function after the header is separated. [0003] After investigating the existing separation and separation electrical connectors in China, for short-circuit proof plug connectors, there are already plug connectors with double-layer insulator components, which are u...
