Abstract

The utility model relates to an adjustable general plug for a single-phase power supply. The base position connected with the bolt of the phase wire and the bolt of the earth is respectively provided with an arc slot extending to the direction of the bolt connected with the earth wire and a straight slot extending to the direction of center. The bolt connected with the phase line can move along the arc slot around the vertical axis positioned on the base. The bolt connected with the earth wire can be bent by 90 DEG around the movable pin positioned on the inner side of the base, and is buried in the straight slot. The utility model has the advantages of novel and reasonable design. The utility model is a universal plug which can be inserted into both a three-pole socket and a double-pole socket. One object realizes two purposes, taking convenience to people to use electric appliance and eliminating the accident threat caused by unreasonable plug use.

Description

The adjustable common pin of single phase poaer supply

The utility model includes the electric apparatus connector of current-carrying pin, sheet or similar contact, relates in particular to the adjustable common pin of a kind of single phase poaer supply.

Single-phase no ground pin has only two latches, claim two-wire plug again, and single-phasely there is ground pin that three latches are arranged, claim three-terminal polarized plus plug again, above-mentioned two class plugs respectively with single-phase two utmost points, three pole sockets are matched and can not exchange adapted, and two-wire plug is inserted three pole sockets by force, insert two pole sockets behind the latch of the earth connection that perhaps three-terminal polarized plus plug fractureed by force, all may destroy connector assembly, cause and use electrification.

The purpose of this utility model is to remedy the deficiencies in the prior art to propose the adjustable common pin of a kind of single phase poaer supply.

The purpose of this utility model is achieved by the following technical programs.

The adjustable common pin of this single phase poaer supply, comprise the insulation crust of forming by the lid and bottom seat, place the interior end of shell to be provided with three flat latches of terminal screw, and wire clipping component, it is characterized in that being provided with an arc groove that extends towards the latch direction of earth connection at the base position of the latch of phase-connecting wire, the latch of phase-connecting wire can move along the arc groove around the vertical shaft that places base, when this latch is positioned at the top of arc groove, form 60 ° of angles with the latch of connecting to neutral line, and spacing meets the national standard of three-terminal polarized plus plug, and when being positioned at the terminal of arc groove, parallel with the latch of connecting to neutral line, and spacing meets the national standard of two-wire plug, also be provided with one at the base position of the latch of earth connection and extend 90 ° the straight trough of going for a stroll towards center position, the latch of earth connection can be around 90 ° of the removable pin bendings that places the base inboard, and imbed in the straight trough.

The utility model is novel, and is reasonable in design, its essence is existing single phase poaer supply is made improvements with the three-terminal polarized plus plug structure.The latch of connecting to neutral line is not changed, it still is Fixed latches, the latch of phase-connecting wire makes mobile latch into, the latch of earth connection is selected latch instead, thereby, it is become a kind ofly both can insert three pole sockets, can insert the universal plug of two pole sockets again, realize dual-use material, offer convenience, especially can eliminate the accident potential that unreasonable use attaching plug brings for people use electrical equipment.

Accompanying drawing is a structural representation of the present utility model.

The contrast accompanying drawing is also made an explanation to the utility model in conjunction with the embodiments below.

The adjustable common pin of the single phase poaer supply of embodiment, comprise the insulation crust of forming by lid and bottom seat 1 (base 1 only draws in the accompanying drawing), place the interior end of shell to be respectively equipped with terminal screw 5,6, three flat latches 2 of 7,3,4, and wire clipping component (also not drawing in the accompanying drawing), be provided with an arc groove 10 that extends towards latch 4 directions of earth connection at the base position of the latch 3 of phase-connecting wire, the latch 3 of phase-connecting wire can move along arc groove 10 around the vertical shaft that places base 1, when latch 3 is positioned at the top of arc groove 10, it is position shown in the accompanying drawing, form 60 ° of angles with the latch 2 of connecting to neutral line, and spacing meets the national standard of three-terminal polarized plus plug, and when being positioned at the terminal of arc groove 10, parallel with latch 2, and spacing meets the national standard of two-wire plug, also be provided with a straight trough 9 that extends towards center position at the base position of the latch 4 of earth connection, the latch 4 of earth connection can be around 90 ° of the removable pin bendings that places base 1 inboard, and imbed in the straight trough 9, and the latch 4 of earth connection is installed on the plug housing 8.

With 90 ° of latch 4 bendings of earth connection, and imbed in the straight trough 9, the latch 3 with phase-connecting wire moves to the terminal position along arc groove 10 again, and present embodiment promptly becomes two-wire plug, can with two pole socket adapteds.And with latch 4 straightening of earth connection, and the latch 3 of phase-connecting wire moved to the position, top along arc groove 10, present embodiment promptly becomes three-terminal polarized plus plug, can with three pole socket adapteds.

Claims
