Abstract

The utility model relates to a power source connector, which is a micro safety power-supply socket and a plug. The socket is characterized in that polygonal socket holes are distributed on a socket plate molded in one time. A cylinder electrode openly sawed is respectively fixed in the holes. The plug matched with the electrode is characterized in that the electrode is a polygonal non-metal sleeve. Power cords fixed on a conical copper electrode openly sawed, the plug and the socket in the sleeve can be exchanged optionally. The plug and the socket are matched and closely combined. The utility model has the advantages of safe and convenient operation, small volume, material saving, money saving, etc.

Description

Miniature safety power source plug socket and plug

The utility model relates to power connector, specifically a kind of miniature safety power source plug socket and plug.

In daily life, the most generally the power connector of Shi Yonging is the plug that exposes of removable box-like socket and electrode up and down, and its weak point is, will take lid apart during the socket thread-changing, formality is loaded down with trivial details, and the exposed electrode of plug is longer, and when not pulling up fully with the hand-lifting plug sometimes, finger is run into the electrode copper sheet and got an electric shock, danger close, in addition, use socket for a long time, the other spring of copper sheet fluffs the plugs and sockets loose contact is opened circuit in the hole.As inserting two simultaneously more than the plug, also easily loose contact and opening circuit.

The purpose of this utility model is to avoiding above-mentioned weak point of the prior art to provide a kind of volume little, safe and convenient to use, economic and lasting miniature safety power source plug socket and plug.

The purpose of this utility model can reach by following measure:

A kind of miniature safety power source plug socket, form by dismountable socket 1 and socket aperture 2, its special character is, be distributed with polygonal socket hole 2 on the socket 1 of single injection-molded, the hole internal fixation has crown saw open form electrode 3, and the jack 6 of power line through the socket side screws with the metallic screw 5 that has Bakelite Cover and cooperate.

The design feature of miniature safety powr supply plug is, can be fixed with circular cone in the nonmetal sleeve 8 of polygon and cut type copper electrode 9, and electric wire stretches into through plug body 7 lower ends and be fixing by terminal screw 10.

Accompanying drawing and description of drawings:

Accompanying drawing 1 is miniature safety power source plug socket contour structures schematic diagram.

Accompanying drawing 2 is that miniature safety power source plug socket A-A is to cross-sectional view.

Accompanying drawing 3 is a pentagon socket aperture structure enlarged drawing (section).

Accompanying drawing 4 is the miniature safety powr supply plug structural representation of two-phase.

Accompanying drawing 5 is a circular hole plug electrode structural representation in the pentagon plastic cement.

Accompanying drawing 6 is miniature safety powr supply plug internal structure schematic diagram.

Among the figure: 1-socket, 2-pentagon socket aperture, 3-crown saw open form copper electrode, 4-external fixation screw, the metallic screw of 5-band Bakelite Cover, 6-power line jack, 7-plug body, circular hole sleeve in the 8-pentagon plastic cement, the 9-circular cone cuts the type copper electrode, 10-terminal screw, 11-plug-in power pack line jack, the 12-electrode wires, the 13-copper sheet.

The utility model is described further below in conjunction with accompanying drawing embodiment:

As shown in Figures 1 and 2, miniature safety power source plug socket contour structures and A-A are to cross-sectional view, socket 1 is the plastic part of single injection-molded, be distributed with the pentagon socket aperture 2 that to accept three-phase and two phase electricity on the plate face of socket 1, as shown in Figure 3, be injected with crown saw open form copper electrode 3 in the pentagon socket aperture 2, each tube bottom is joined by copper sheet 13 and joins with power line, metallic screw 5 with two on the socket 1 band Bakelite Covers is tightened, and contact firmly.Need not loam cake be opened during the transposing power line, because the peg loam cake is a bakelite, so thread-changing can not got an electric shock safe ready again.

Be the contour structures schematic diagram of the miniature safety powr supply plug of two-phase electrode as shown in Figure 4, be injected with circular hole sleeve 8 in two pentagon plastic cement among the figure on the plug body 7, in it as shown in Figure 5, circular cone is installed cuts type copper electrode 9, the gap width that copper electrode cuts is 1 millimeter, can insert power line in the power line jack 11 of plug body 7 afterbodys and electrode wires 12 is joined, tighten fixing by terminal screw 10.

During use, in the pentagon socket aperture 2 on the 8 insertion sockets 1 of circular hole sleeve in the pentagon plastic cement on the plug body, itself all have elasticity because crown saw open form copper electrode 3 and circular cone cut after the shape fastener cuts, thereby contact with each other closely, outage can not come off.Circular hole sleeve 8 cuts type copper electrode 9 parcel with circular cone when extracting this plug because in the pentagon plastic cement, even thereby in the unplugg process hand contact plug electrode can not get an electric shock yet, this plug, socket only need parbuckle screw when changing power line.

The utility model has following advantage compared to existing technology:

1, the Miniature safety supply socket is combined with plug closely, and is safe and convenient to use.

2, this plugs and sockets is single injection-molded spare, and it is little to save the part volumes such as spring, Save raw material, comparing production cost with plug, the socket of existing same function will descend At least 50%.

Claims
