Abstract

The utility model discloses a power socket which is composed of a power contact point with more than one phase and an indicator, wherein, a socket contact point is composed of a static contact piece, a movable contact piece, a supporting screw and a supporting spring. When a plug is not inserted in the socket or the plug is partially inserted in the socket, the jack at the upper part of the contact point of a socket box is uncharged. When the plug is completely inserted in the bottom of the socket, the power is conducted.

Description

Power supply socket

The utility model is a kind of supply socket, is applicable to the supply socket that each electric appliances is required.

The existing used supply socket of each electric appliances is that two power contacts more than extremely are being set on the pedestal of socket, for electrical equipment the function of energized is only arranged, and can not show whether switch on.The conducting of power supply with by controlling by hand switch; When socket did not use, the Metal Contact sheet was still charged, did not fill out slightly just to produce and got an electric shock; The supply socket technology of present charged source indicating device, its complex structure needs to use the transformer transformation, and electric appliance load power is had specific scope restriction.

The purpose of this utility model is that design is a kind of without the transformer transformation, without hand switch control power supply by and conducting, the emergency power supply socket that constitutes by contact chip and power indicator.

The utility model is by the supply socket that single-phase above power contact and indicating device constitute is set.Wherein by static contact 1, the conducting that movable contact spring 2, supporting screw 3, support spring 4 constitute power contacts with end; Static contact 1 bottom is partially submerged into the socket box bottom, and an end that is  shape is drilled with screw, above power firestreak lead head is fastened on screw; Movable contact spring 2 planes are provided with live wire and patch sheet 5, hole 6, hole 7 are placed on supporting screw 3 and support spring 4 upper ends, it is high in order to the distance of regulating between movable contact spring 2 and the contact, static contact 1 upper surface that nut 8 is screwed into supporting screw 3 upper ends, when plug does not insert socket or insertion portion, because movable contact spring 2 does not contact with the contact, it is not charged to patch sheet 5, and socket box internal plug seat top is not charged to making; When plug inserts movable contact spring 2 is contacted with contact 8, patch sheet 5 conductings, power supply is conducting; Be connected in series a neon bulb 9 and current-limiting resistance R between zero line and movable contact spring 2, neon bulb 9 is as the conducting and the disconnection of indicator for displaying power supply, the zero line conductor wire end and patch sheet with copper sheet and screw at the socket box inner bottom part.

The utility model is on the small-sized single-phase double wire system porous socket box of the universal standard, and single-phase above power contact and power indicator are set, and it makes simple, uses this supply socket safe and convenient.

Implement the utility model and can with the small-sized single-phase double wire system porous socket shell box of GB, be provided with copper sheet punching out one-tenth static contact 1 and movable contact spring 2 as shown in Figure 3 in the box according to shown in Figure 1; Supporting screw 3 is with thin copper pipe, puts support spring 4 at thin copper pipe shell simultaneously, adopts glow discharge not have dynamic neon bulb according to the neon lamp between serial connection zero line shown in Figure 2 and the movable contact spring 2, and resistance R is selected

W small-power resistance.

Claims

1. supply socket that constitutes by power contact more than single-phase and indicating device, it is characterized in that static contact 1 one ends that copper sheet is made are  shape, the bottom is partially submerged into the socket box bottom, power firestreak lead head is fixed tightly on the screw of  shape end with screw, on movable contact spring 2 planes live wire is set and patches sheet 5, hole 6 on the movable contact spring 2, hole 7 is placed on supporting screw 3 and support spring 4 upper ends respectively, nut 8 is screwed into supporting screw 3 upper ends in order to regulating distance between movable contact spring 2 and the contact, static contact 1 upper surface, and indicating device and resistance string are connected on movable contact spring 2 and are fixed on having between the zero line that patches sheet bottom the socket box.
