Abstract

The utility model relates to an indication-roll type general power-supply plug for wiring, composed of an insulation shell, conducting wire and plug pieces. The plug pieces are provided with a gear which can adjust the included angle between the two plug pieces. A terminal box is arranged in the insulation shell. A roller is arranged in the terminal box, and a metal sheet and a connector of the conducting wire can be compressed and connected together by the roller. A circuit connected with an indicator light and a resistor in series is connected between the two plug pieces in parallel. The utility model can be used on a two-foot socket and a three-foot socket universally with convenient connection. The condition of the power supply in the circuit can be judged immediately.

Description

Indication-roll type wiring universal electric power plug

Indication-roll type wiring universal electric power plug belongs to a kind of attaching plug that is used in combination with common socket.

There are three big problems in present attaching plug: first wiring is very because of difficulty; The second, two-pin plug and three-pin socket can't be general; The 3rd, the back that plugs in is if power supply is undesired, and can't determine the end immediately is that power supply does not have electricity or the circuit or the electrical appliance of plug back have problem.

The purpose of this utility model is to provide a kind of wiring very convenient, and a plug can be general on bipod socket and three-pin socket, can indicate the indication-roll type wiring universal electric power plug whether electricity is arranged on the socket again.

The utility model is made up of insulation shell, lead, plug blades etc., it is characterized in that: the pitch wheel and the driven gear of the angle that can regulate two plug blades are housed respectively on two plug blades, realize a plug general purpose on bipod socket and three-pin socket; Insulation shell at plug is built-in with terminal box, has tightly to be crimped on together roller to sheet metal and terminal in terminal box, realizes convenient for wiring purpose; Between two plug blades and connect one by indicator light and circuit after resistance is connected in series, the back that plugs in just can be judged the power supply situation of circuit immediately.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Accompanying drawing 1 is the vertical view after the utility model removes a half of insulation shell;

Accompanying drawing 2 is A-A face cutaway views;

Accompanying drawing 3 is B-B face cutaway views.

In the accompanying drawings, [10] are plug blades, and pitch wheel [8] and driven gear [9] are housed respectively on two plug blades [10].Gear [8] both can be as accompanying drawing 1 protrudes from the side of insulation shell [2], also can be as accompanying drawing [3] from wide protrusion of insulation shell [2].Transmitting gear [8], driven gear [9] also will rotate thereupon, and two gears will drive two plug blades [10] and all rotate, thereby adjust the angle between two plug blades [10], realize a plug general purpose on bipod socket and three-pin socket.Two terminal boxes [4] are arranged in insulation shell [2], and there is socket [3] at the two ends of terminal box [4] bottom, go up in terminal box [4] to also have roller axial trough [5], and roller [6] is arranged in terminal box [4], and the axle that cooperates with roller axial trough [5] is arranged on roller [6].One end of sheet metal [7] is connected with plug blades [10], and the other end inserts in the terminal box [4] from socket [3], and scroll wheel [6] tightly is pressed in the joint that inserts the lead [1] in the terminal box [4] on the sheet metal [7] and has just connected.Tighter in order to allow the joint of lead [1] contact with sheet metal [7], the wheel that is preferably in roller [6] is along some anti-slop serrations of last work, and simultaneously, one that allows roller axial trough [5] guiding line [1] enter has a tiny inclination angle.In order in time to judge the power supply situation in the circuit, between two sheet metals [7] or plug blades [10], be connected to indicator light [12] and resistance [11].Indicator light [12] preferably places within the indication socket [13] so that observe.After plugging in, indicator light [12] brightness is normal, illustrates that power supply is normal; Brightness is not enough, and account for voltage is on the low side; Do not work, then illustrating on the socket does not have.

The utility model has the advantages that: the first, can be general on bipod socket and three-pin socket, the second, wiring is very convenient, The 3rd, can immediately judge the power supply situation in the circuit.
