Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plug-in type electric wire connector.

[0002]

2. Description of the Related Art Conventionally, a wire connecting device such as a plug is constructed by protruding a metal blade from an insulating case, and inserting this blade into the insertion hole of another corresponding connecting device. The blades are brought into contact with each other so that the electric wires can be connected. When pulling out the wire connection tool, hold down the other connection tool with one hand and pull the wire connection tool with another hand, but the handicapped person with weak hand, the sick person or the elderly with weak strength are required. However, it was difficult to pull out the above-mentioned conventional electric wire connector.

Therefore, as a plug-in type electric wire connector which can be pulled out with one hand, as shown in FIG. 5, a receiving blade is embedded inside an insulator a, and a corner b of the insulator a is sandwiched and crossed. A pair of insertion holes c, c are formed along the fan shape extending between the two surfaces, and the rear end reaches the internal blade, and a protrusion is formed in the lower part between the insertion holes c, c on the surface of the insulator a. An outlet provided with d is proposed.

In this device, when the plug blade of the plug is inserted into the insertion holes c, c on the side surface where the projection d is formed, the socket blade of the outlet and the plug blade of the plug are brought into contact with each other, and the insulator portion of the plug is removed. When pinched and rotated so as to press it against the protrusion d of the outlet, the protrusion d is pressed by the plug to prevent the outlet from rising, and the plug blade of the plug rotates along the insertion holes c, c. The plug is pulled out from the insulator a through the other side surface that intersects the side surface on which the protrusion d is formed, and is pulled out. Therefore, it is possible to easily remove the plug from the outlet by rotating the plug with one hand, but since the inner edges of the insertion holes c, c of the outlet are formed along a relatively long arc, the plug can be inserted. If the position is deviated, the blade may not come into contact with the blade inside the outlet or may come into contact at an incomplete position.

DISCLOSURE OF THE INVENTION The present invention provides an electric wire connector which can be easily pulled out only by operating one hand and which can surely bring the contact into contact with the contact of another corresponding connector. The purpose is to do.

[0006]

The electric wire connector of the present invention comprises:
In order to achieve the above object, a contact is rotatably provided at one end of the grip, and a protrusion is provided so as to project to the side of one end of the grip in the direction of rotation of the contact. The protrusion may project from both sides of one end of the grip.
Three or more contacts may be provided.

[0007]

When the grip of the wire connector inserted in the insertion hole of another connector is turned to the side where the protrusion is projected, the tip of the protrusion serves as a fulcrum of the lever. While pressing the connecting tool, the one end of the grip portion moves away from the other connecting tool. As a result, the contact is rotated with respect to the gripping portion and is withdrawn from the insertion hole that maintains the posture in which it intersects at right angles with the insertion surface of the other connection tool.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, an electric wire connector 1 includes a grip portion 2 made of an insulating material, and a pair of contacts 3 rotatably protruding from one end surface of the grip portion 2. Equipped with. The grip portion 2 has a flat shape in which one end is wide and the other end is narrow, and is configured by assembling one side member and the other side member that are divided into two in the thickness direction. Further, a cavity portion 4 having an opening on one end face side is formed inside one end portion of the grip portion 2, and an electric wire insertion passage 5 reaching the cavity portion 4 from the other end portion is formed. Further, on one side surface in the thickness direction of one end of the grip portion 2, a projection 6 having a smoothly curved tip is provided integrally so as to project laterally.

The contacts 3 and 3 are formed in an appropriate shape such as a pin shape or a blade shape, and are embedded in parallel with a widthwise interval so that the tips of the contacts 3 and 3 protrude from the rotating base 7 made of an insulating material. Has been done. The rotation base 7 is formed in a cylindrical shape whose diameter and width are slightly smaller than those of the hollow portion 4 of the grip portion 2.

The rotating base 7 is inserted into the hollow portion 4 of the grip portion 2 and is pivotally mounted in its thickness direction via its central axis. As a result, the contacts 3,3
Is projecting from one end surface of the grip portion 2 through the opening of the cavity 4 and is rotatable in the thickness direction. The protrusion 6 provided on one side surface of the grip portion 2 rotates the contactor 3. It will be projected along the direction. Furthermore, the end of the electric wire 8 inserted into the electric wire insertion path 5 from the other end of the grip portion 2 is connected to the contacts 3 and 3.

The wire connector 1 is used as follows. In FIG. 2, the other connector 9 corresponding to the wire connector 1 is a general outlet, and the wire connector 1 and the other connector 9
Is a contactor 3,3 like a normal plug and outlet
Is inserted into an insertion hole (not shown) of another connecting tool 9 to be connected.

When disconnecting the wire connector 1 from the other connector 9, as shown in FIG. 3, when the grip portion 2 is picked up and pivoted along the arrow A toward the protrusion 6, the protrusion 6 is removed. The tip serves as a fulcrum of the lever and presses the other connecting tool 9 downward in the figure,
The grip portion 2 is inclined and one end surface of the grip portion 2 is lifted above the other connecting tool 9. However, since the contacts 3 and 3 can be rotated with respect to the grip portion 2, even if the grip portion 2 is tilted, the contacts 3 and 3 maintain the posture of intersecting at right angles with the insertion surface of the other connecting tool 9, As one end surface of the grip portion 2 separates from the other connecting tool 9, it slides in the direction of arrow B along the insertion hole, and finally the wire connecting tool 1 is pulled out from the other connecting tool 9.

FIG. 4 shows another embodiment, in which the projections 6a are projected from both side surfaces of the grip portion 2a in the thickness direction. With this configuration, the wire connector 1a can be pulled out from the other connector regardless of which side of the grip 2a in the thickness direction is rotated. The number of the contacts 3 is not limited to two as shown in the figure, and three or more contacts 3 may be provided in one row or a plurality of rows.

[0014]

According to the first aspect of the present invention, when the gripping portion is picked up and pivoted to the side where the projecting portion is projected, the tip of the projecting portion serves as a fulcrum of the lever and the electric wire connector is inserted. At the same time as pressing the connecting device in the direction opposite to the pulling direction, the contactor can be smoothly pulled out while maintaining the posture of intersecting the insertion surface of the other connecting device at a right angle. Since there is no need to hold the hand by hand and the force required to pull it out is weak, even a physically handicapped person who is only able to use one hand or an elderly person or a sick person with weak strength can easily pull it out from another connecting device. In addition, since it is not necessary to make the insertion hole of other connecting device a special shape, when connecting the electric wire connecting device to the other connecting device, there is a possibility that the contacts will not be contacted or the contact will be incomplete. Absent.

According to the second aspect, it is possible to pull out the grip portion even if the grip portion is turned to any side along the turning direction of the contact.
