An external electronic device having and as an external connection terminal portion, wherein the case body 1 is formed in a substantially H-shaped cross section by forming a cord winding cylinder 6 in a central portion thereof.
The movable plug portion 2 has two stop positions and is movably mounted on one of the protruding walls 7, and the cord winding cylinder 6 is attached to the movable plug portion 2 at any stop position.
It is achieved by providing an external electronic device that is provided above the cord winding body 6 and has a pressing piece 8 that presses down the drawn cord 4 wound around the cord winding body 6.

[Action]

Based on the above configuration, the external electronic device of the present invention is configured by mounting the movable plug portion 2 on the case main body 1 having the cord winding cylinder 6, and when not in use, the pull-out cord 4 is provided with the cord winding barrel 6. It is wound and stored. The movable plug portion 2 having two stop positions and movably attached to the case body 1 is provided with a pressing piece 8 projecting therefrom, and is drawn out by the cord winding body 6 and stored. Prevent rewinding of 4.

【Example】

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 to 4 show an embodiment of the present invention, in which 1 is a case main body, 2 is a movable plug part mounted on the case main body 1, 4 is a withdrawal cord withdrawn from the case main body 1, Reference numeral 9 is a plug as a device connecting portion 5 attached to the tip of the pullout cord 4. The case body 1 is formed in a substantially H-shape in a side view by forming projecting walls 7, 7 at both ends of a cord winding body 6 provided in the central portion, and is drawn out from the inner wall surface of one projecting wall 7. The cord 4 is pulled out, and when the cord 4 is not used, the withdrawal cord 4 can be wound around the cord winding cylinder 6 and stored. In addition, on the inner wall surface of the protruding wall 7, a locking hole 12 for locking a locking piece 11 described later is provided, and
The other protruding wall 7 arranged to face the protruding wall 7 includes:
A U-shaped notch 13 for pivotally mounting the movable plug portion 2 is formed. Further, a pair of plug holding notches 14 and 14 are provided in the pair of projecting walls 7 so as to face each other and to be recessed.
Thus, both ends of the plug 9 can be sandwiched and held (see FIG. 2). On the inner wall surface of the U-shaped notch 13, as shown in FIG.
A hinge hole 18 in which 16 and the lower lead-out portion 17 are formed is opened facing each other, and the movable plug portion 2 is supported by inserting the hinge protrusion 19 into the hinge hole 18. further,
A connector 21 to be connected to a connector 21 of the movable plug portion 2 described later is mounted on the bottom wall portion of the U-shaped notch 13 and is connected to the outlet plug-in terminal 3 of the movable plug portion 2 via the connector 21. It is connected to the internal circuit. On the other hand, as shown in FIG. 6, the movable plug portion 2 is formed in a substantially L-shape in a side view with a pressing piece 8 protruding from the side of the main body portion holding the outlet plug-in terminal 3. A connector 21 to be connected to the connector 21 of the case body 1 described above is provided in a portion orthogonal to the outlet insertion terminal holding surface 22 of the above, and an oval hinge projection 19 is formed on both side walls of the lower end portion. . The pressing piece 8 is the cord winding body 6 of the case body 1 described above.
Is formed so as to have a protruding length substantially the same as the longitudinal dimension of the holding piece 23 in the holding hole 23 having an opening facing the free end.
Is attached so that it can move back and forth. This locking piece 11 has a spring 24.
Is urged by the pressing piece 8 in a direction projecting from the pressing piece 8, and an operating element 26 exposed from an operation opening 25 formed on the upper surface of the pressing piece 8 is fixed to the upper surface of the locking piece 11. The locking piece 11 can be completely stored in the holding hole 23 by operating the operator 26. Next, a method of using the external electronic device according to this embodiment will be described with reference to FIGS. 7 to 10. FIG. 7 shows that after the withdrawal cord 4 is wound around the cord winding cylinder 6 of the case body 1 to store the external electronic device,
This figure shows a state in which the plug 9 is press-fitted and retained in the plug retaining notch 14, and the movable plug portion 2 in the use state of the external electronic device and the state shown in this figure has the outlet plug-in terminal 3 on the case body 1 side. It is held at a position projecting from one side, and the connectors 21 are connected to each other so that the internal circuit and the outlet plug-in terminal 3 are electrically connected to each other, and the hinge protrusion 19 of the movable plug portion 2 is provided.
Fits into the side pull-out portion 16 of the hinge hole 18 to form the stop position of the movable plug portion 2 (see FIG. 7 (a)). When the movable plug portion 2 is pulled in the direction of the arrow in FIG. 7 (a) from this state, the hinge protrusion 19 moves to the side while releasing the fitting with the side pullout portion 16, and the hinge hole 18 Round part
It collides with 15 and stops (see FIGS. 8 (a) and 8 (b)).
After that, when the outlet plug-in terminal 3 is rotated about 90 degrees in the direction of the arrow in FIG. 8 (a), the hinge protrusion 19 rotates within the perfect circle portion 15 of the hinge hole 18 and the pressing piece 8 is pressed.
The tip of the locking piece 11 that protrudes from the protruding wall 7 of the case body 1
After it comes into contact with the housing, it is housed in the holding hole 23 (Fig. 9 (a)).
reference). Next, when the pressing piece 8 is pushed in the direction of the arrow in FIG. 9 (a), the hinge protrusion 19 of the movable plug portion 2
Is guided by the lower drawer portion 17 of the hinge hole 18 and descends,
It abuts against the bottom wall surface of the lower drawer portion 17 and stops (see FIG. 10 (b)). In this state, since the opening of the pressing piece 8 faces the locking hole 12 of the protruding wall 7, the locking piece 11
Enters the locking hole 12 and blocks the upward movement of the movable plug portion 2. As a result, the pull-out cord 4 is pressed by the pressing piece 8 and rewinding is prevented. As described above, in order to put the withdrawal cord 4 around the cord winding cylinder 6 into a use state from the state of being stored, first, the operator 26 of the pressing piece 8 is moved in the arrow direction in FIG. 10 (a). After moving and releasing the lock between the lock piece 11 and the lock hole 12, the outlet plug-in terminal 3
It suffices to move the case to a position protruding from the case body 1. In the above description, the case where the movable outlet portion 2 is positioned by using the fitting state of the hinge protrusion 19 and the hinge hole 18 has been shown, but various other mechanisms can be used. is there.

[Effect of device]

As is apparent from the above description, according to the external electronic device of the present invention, the withdrawal cord can be reliably stored and the storability can be improved.
