Earthed telescopic meshed-type civil electrical connecting device as well as plug and socket thereof

Abstract

The invention provides an earthed telescopic meshed-type civil electrical connecting device as well as a plug and a socket thereof. The earthed telescopically-meshed civil electrical connecting device is particularly suitable for wired or wireless plugs, fixed or movable sockets, interconnecting couplers, appliance couplers and the like used for the indoor or outdoor. The earthed telescopically-meshed civil electrical connecting device comprises a rotary springback meshed-type electrical connecting plug and a rotary spirngback meshed-type electrical connecting socket, wherein the rotary springback meshed-type electrical connecting plug is provided with a metal contact A and the like, the rotary spirngback meshed-type electrical connecting socket is provided with a metal contact B and the like, and the metal contact A and the metal contact B are electrically connected through mutually meshing under the action of an earthed telescopic spring mechanism. The earthed telescopic meshed-type civil electrical connecting device has the advantages of wide application range, simple structure, simplicity and convenience in operation, reliable connection performance and capability of ensuring that earthed metal contacts are firstly connected, and then a firing line and a zero line are connected when the connecting device is spliced every time, ensuring that the firing line and the zero line are firstly disconnected, and then the earthed metal contacts are disconnected when the connecting device is pulled out, ensuring that the firing line and the zero line are uniform and reliable in contact pressure, ensuring safety and preventing accidental electric shock.

Description

technical field [0001] The invention relates to a grounding telescopic engaging type civil electrical connection device and its plug and socket, which are mainly suitable for indoor and outdoor civil plugs with or without wires and fixed or mobile plugs with a rated voltage not exceeding 250V. receptacle and interconnection couplers, appliance couplers, etc. Background technique [0002] At present, the common civilian plug sockets and couplers are directly plugged in, that is, plug in—power on, pull out—power off; the plug of the electrical appliance is directly inserted into the jack of the socket with the power supply or directly In the coupler with power supply, the purpose of using electricity is achieved. This kind of plug socket or coupler is relatively simple and convenient, but it cannot guarantee synchronous insertion, resulting in frequent "arcing", damage to electrical appliances, and even electrical accidents; this kind of plug socket or coupler grounding is un...

AI Technical Summary

Problems solved by technology

[0003]In order to overcome the disadvantages of existing civilian plug sockets and couplers such as unsafe, dangerous, unreliable grounding, high failure rate, and poor reliability, it is especially necessary to eliminate The hidden dangers of "the ground wire, the live wire, and the neutral wire are connected at the same time and separated at the same time". At the same time, it is necessary to ensure uniform contact pressure and high contact reliability. A reliable connection between the grounding metal contacts is proposed. The effective stretching and meshing of the type elastic mechanism can reliably ensure that the grounding metal contacts are connected first when the connecting device is plugged in each time, and then the live wire and the neutral wire are connected again. The final separation between the grounding metal contacts has simple structure, convenient use, uniform contact pressure, safety and reliability, and low cost. The connection of the grounding wire is completed by the expansion and contraction of the grounding metal body. A kind of grounding telescopic engagement type civil electrical connection device and its plug and socket which are connected with the grounding metal contact B and connected reliably, so as to make up for the current shortage
