BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plug device for an electric device, and more particularly, to a plug device for rotating a plug assembly on one surface of a main body case of the electric device such that a tip end of a plug blade projects forward of the case. The present invention relates to a plug device for an electric device which is attached by mounting.

[0002]

2. Description of the Related Art As a plug device of this kind of electric equipment,
As described in Japanese Utility Model Laid-Open Publication No. 2-31074, two openings for accommodating a plug assembly and operation buttons are provided on the front surface of a rear case constituting a main body case containing a secondary battery. The plug assembly is attached to the main body of the plug assembly by rotatingly biasing the plug assembly in a direction protruding forward of the rear case, and a plug blade that comes into contact with the contact piece of the secondary battery connection plug when the plug assembly rotates. In addition to the above, the operation button urged by the urging member to another opening of the rear case is formed by forming an engagement concave portion for locking the plug assembly after rotation with the claw portion of the contact support plate in the main body case. The operation button is provided by attaching so that it does not fall off from the rear case, and by providing an engagement projection on the upper part of the operation button that comes into contact with the lower end face of the plug body but releases the contact with the plug body when pressed. Press There is to automatically project the plug assembly in one-touch operation.

[0003]

By the way, in the above case, the plug blade and the plug assembly housed in the case are resiliently contacted or engaged with the contact points and claws of the connection plug. Is provided. Therefore, when the operation button is pressed to cause the plug assembly to protrude, these contacts and claws act as a resistance to the rotation of the plug assembly, and the plug assembly may not be smoothly protruded. In particular, in order to improve the electrical connection between the contact point and the plug blade and the support of the plug assembly by the claw portion, respectively,
When the elastic force is increased, the plug assembly becomes more difficult to protrude smoothly.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a plug device for electric equipment in which a plug assembly can rotate smoothly and a plug blade can be easily protruded.

[0005]

According to the present invention, there is provided a plug device for an electric device, wherein a plug assembly having a plug body provided with a plug blade is provided on one surface of a main body case. An electrical contact that elastically contacts the rear end side of the plug blade when the plug blade protrudes, and is elastically engaged with the plug main body. A holding member for holding the plug blade in a protruding state, and a first position in contact with the plug assembly so as to hold the plug blade in a position to be stored in the main body case; An operating member operable at a second position for releasing the contact and retracting the electrical contact and the holding member in a direction away from the plug assembly is provided.

[0006]

According to the present invention, the operating member is moved from the first position to the second position.
When operated to the position, the contact with the plug assembly is released,
The plug assembly is rotated by the rotation urging force applied thereto, and the plug blade projects forward of the main body case. At this time,
The electrical contact and the holding member are retracted in a direction away from the plug assembly, and they come into contact or contact with each other when the plug assembly rotates, and act as a resistance to the rotation of the plug assembly. Absent.

1 and 2 are a perspective view and a longitudinal sectional view, respectively, showing an embodiment of the present invention. 1 is a main body case, 2 is a plug storage recess provided at the upper part on the back side of the main case 1, and 3 is a plug assembly rotatably arranged in the plug storage recess 2. The plug assembly 3 includes a plug body 3a and a pair of plug blades 3b provided on the plug body 3a. Plug blade 3b
Is provided so that the rear end side thereof slightly penetrates the plug body 3a. Also, on the back side of the plug body 3a,
An engagement recess 4 is provided between the plug blades 3b.

Reference numeral 5 denotes a spring body which is provided at an end of the plug main body 3a and biases the tip of the plug blade 3b in a direction protruding forward on the back side of the main body case 1, and 6 is disposed in the main body case 1. When the plug blade 3b protrudes, the plug blade 3b
Is an electrical contact that elastically makes electrical contact with the rear end side, and is made of a conductive elastic body. Reference numeral 7 denotes a printed circuit board that supports one end of the electrical contact 6, and reference numeral 8 denotes a state provided at a position behind the plug main body 3a, in which the plug main body 3a rotates and the plug blade 3b protrudes (the state indicated by a two-dot chain line in FIG. 2). The holding member elastically engages with the engaging recess 4 of the plug body 3a and holds the plug blade 3b in a protruding state.

Further, reference numeral 9 denotes an operating body which is disposed below the plug housing recess 2 so as to be vertically movable. Specifically, the operating body 9 holds the plug blade 3b in the first position (the first position where the upper end contacts the rear end side of the plug blade 3b so as to hold the plug blade 3b in the position where the plug blade 3b is stored in the plug storage recess 2 of the main body case 1). Upper position)
And releases the contact with the plug blade 3b, contacts the lower contact of the electrical contact 6 and the holding member 8, and retracts them in the direction away from the plug assembly 3 (the direction indicated by the arrow in FIG. 2). It can be operated to a second position (lower position).
Reference numeral 10 denotes a spring that urges the operating body 9 upward to always keep the operating body 9 at the first position.

In such a configuration, when the plug blade 3b is stored in the plug storage recess 2, the upper end of the operating body 9 located at the first position by the urging force of the spring 10 causes the plug blade 3
b abuts on the back side of the rear end side. Therefore, the plug body 3
“a” is not rotated by the rotation urging force of the spring body 5, and the plug blade 3 b maintains the state stored in the plug storage recess 2.

Next, when the operating body 9 is moved to the second position (downward position), the contact between the operating body 9 and the plug blade 3b is released. Accordingly, the plug main body 3 a is rotated by the rotational urging force applied by the spring body 5, and the plug blade 3 b projects from the main body case 1. At this time, the electrical contact 6 and the holding member 8 are retracted in a direction away from the plug assembly 3 (a direction indicated by an arrow in FIG. 2), and these contact or abut on the plug body 3a and the plug blade 3b. do not do. Therefore, the plug main body 3a rotates smoothly. Then, the holding member 8 is engaged with the engaging concave portion 4 of the plug main body 3a, and the plug blade 3b is securely held in a protruding state.

[0012]

According to the present invention, a plug device for an electric device according to the present invention rotates a plug assembly having a plug body provided with a plug blade on one surface of a main body case in a direction in which a tip side of the plug blade projects forward of the case. An electrical contact that elastically contacts the rear end side of the plug blade when the plug blade is protruded into the main body case; and the plug blade protrudes by being elastically engaged with the plug main body. And a first position for contacting the plug assembly so as to hold the plug blade in a position for storing the plug blade in the main body case, and release the contact with the plug assembly. And an operating member operable at a second position for retracting the electrical contact and the holding member in a direction away from the plug assembly, so that the plug body can be smoothly rotated, and the plug can be easily plugged. It can be projected.
