Abstract

The utility model relates to a three hole sockets, its technical scheme is: two groups of contact pieces except the grounding contact piece in the three groups of metal contact pieces are bent, and the convex surfaces of the two contact pieces in each group are opposite. The shape of the jack is matched with the shape of each group of contact pieces, so that the two-pole plug and the three-pole plug can be inserted into the jack and are in good contact. The utility model discloses compare with current three hole sockets, not only can insert the tripolar plug, can also insert the two-stage plug, convenient and practical.

Description

Socket

The utility model relates to a kind of socket.

Three-hole socket in the existing lighting circuit, in its three groups of Metal Contact sheets, the shape of two winding contacts except that the ground connection contact chip lacks perfection, can only inject the sheet metal of three-terminal polarized plus plug, but insert the sheet metal that does not advance the two poles of the earth plug, on the panel except that earth jack two jacks also be so, this just makes Three-hole socket have a defective: can only insert three-terminal polarized plus plug, but can not insert the two poles of the earth plug.

The purpose of this invention is to provide and a kind ofly can insert three-terminal polarized plus plug, can insert the Three-hole socket of the two poles of the earth plug again.

The technical scheme of its solution is: every contact chip of two groups of sheet metals all is bending, the convex surface of two contact chips of every group is relative, the shape of the shape of two jacks and two winding contacts adapts, and the two poles of the earth plug and three-terminal polarized plus plug can both be inserted, and contact is good.

The present invention compares with existing Three-hole socket, not only can insert three-terminal polarized plus plug, can also insert the two poles of the earth plug, and is convenient and practical.

Fig. 1 is the panel of existing Three-hole socket, and Fig. 2 is the Metal Contact sheet of existing Three-hole socket, and Fig. 3 is a panel of the present invention, and Fig. 4 is the Metal Contact sheet of invention.

Realize that best way of the present invention is:

1, execute example (1), camber is done in every contact of two winding contacts, the convex surface of two contact chips of every group is relative, and the shape of the shape of jack and Metal Contact sheet adapts, and three-terminal polarized plus plug and the two poles of the earth plug can both be inserted.

2, execute example (2), every contact chip of two winding contacts is made meander-like, the convex surface of contact chip is relative, and the shape of the shape of jack and Metal Contact sheet adapts, and three-terminal polarized plus plug and the two poles of the earth plug can both be inserted.

Claims

The utility model belongs to a kind of Three-hole socket, it is characterized in that: two groups of Metal Contact sheets have flexure plane, and the convex surface of two Metal Contact sheets of every group is relative; There is the shape with the Metal Contact sheet to adapt, is convenient to the jack that the two poles of the earth plug and three-terminal polarized plus plug insert.
