Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device for attaching and detaching two electrical devices.

Conventional configurations and their problems Portable VTRs and their mounting stands: When used outdoors, the VTR stands alone; when used indoors, it is equipped with a television receiver and an AC power supply. At the same time as engaging and fixing the VTR on the mounting table, making an electrical connection between the two,
There are electrical devices that are used integrally.

As an example of this type of conventional electrical equipment, FIG. 1 shows a portable VTR and its mounting stand.

Fig. 1 shows a mounting stand that incorporates a television channel and an AC power supply, and has a mounting surface 1a on the top surface on which a portable VTR 2 is placed, and guides on both sides of the mounting surface 1a. A frame 1b is provided,
After the portable VTR 2 is placed on the placement surface 1a, the two are engaged and fixed by sliding in the direction of the arrow.

In this engaged and fixed state, the connector 3 provided on the mounting table 1 side and the connector 4 on the VTR 2 side are simultaneously engaged, and the two are electrically connected.

However, with such a configuration, when the VTR 2 is inserted and engaged from diagonally above in a different direction as shown in FIG. 2, the male and female pins of the connectors 3 and 4 are engaged from the diagonal direction, and the 3
Otherwise, 4 was damaged.

Purpose of the Invention In order to solve these problems, the present invention prevents the connector from being connected unless the electrical device is slid in a predetermined direction relative to the main body, and prevents the connector from being damaged due to a large load being applied to it. The purpose of this invention is to provide an attachment/detachment device that is protected against

Structure of the Invention The main body is provided with a connector that is coupled to a connector provided on an electrical device, and the main body is provided with a stopper that prevents the connectors from being coupled to each other and is movably provided at a position where the handset is to be attached. This attachment/detachment device is provided with a release button on the main body that allows the stopper to be retracted only when the electric device is attached in a predetermined direction.

DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings, in which the present invention is applied to an attachment/detachment device for a portable VTR and a main body (mounting base) including a tuner.

As shown in FIG. 3, the portable VTR 5 is horizontally slid from the front to the rear (in the direction of the arrow) as in the conventional example, onto the main body 6 including the tuner.
A connector 7 of a VTR 5 and a connector 8 of a main body 6 are detachably connected. The above configuration is the same as the conventional one, but in the present invention, the connector 8 of the main body 6
A stopper 9 is attached near the. This deck stopper 9 is fixed on a slide plate 10, and this slide plate 10 is attached by a guide rib 10a so that it can slide in the insertion direction of the VTR 5, that is, in the front and back direction, and the stopper 9 is attached to the sliding surface 6a of the main body 6. Through hole 6b provided
more prominent. Further, the slide plate 10 has holes 17 and 18, which have a width l ₂ larger than the width l ₃ of the flange portion 11a of the release button 11, and are provided at regular intervals through which the flange portion 11a passes. The distance between the holes 17 and 18 is such that the front wall 9a of the deck stopper 9 is from the position of the rear surface of the deck 5 when the connectors 7 and 8 are securely connected.
Leave a gap up to the position of the rear surface of deck 5 when it is completely removed. Also, those two holes 1
7 and 18 are connected by a slit of width l ₁ through which the release button 11 can be moved. That is, the width _l1 is set larger than the width of the release button and smaller than the width _l3 of the collar portion 11a.

The release button 11 is passed through the slide plate 10 and the hole 12 of the main body 6 from below, and is pressed from below by a spring 14 whose one end is fixed to the lower surface of the main body 6 with a screw 13 or the like so that it can move up and down. Slide plate 10
One end 15a of the spring 15 is attached to one end, the other end 5b of the spring is fixed to the main body 6, and the slide plate 1
Pull 0 forward.

As shown in FIG. 4A, when the deck 5 is placed on the main body 6 in a predetermined horizontal orientation and slid backward, the release button 11 is pushed downward by the bottom surface of the deck 5. , hole 1 of slide plate 10
8, the collar portion 11a of the release button 11 is removed and the lock is released.

When the deck 5 is pushed in in this state, the deck stopper 9 hits the rear surface of the deck 5, and the deck 5
The connectors 7 and 8 of the deck 5 and the main body 6 are properly connected in a predetermined horizontal state. When the connectors 7 and 8 are completely connected, the collar portion 11a of the release button 11 fits into the hole 17 of the slide plate 10 and moves upward, as shown in FIG. 4B. Recess 1
Enter 6. Then, the slide plate 10 is locked again in this state, and the forward force by the spring 15 is no longer applied to the deck, making it difficult for the joint to come off. However, as shown in Figure 4C, deck 5
If you try to attach it from diagonally above instead of the prescribed horizontal direction, a gap will be created between the bottom surface of the deck 5 and the main body 6, and the release button 11 will not be pushed downward, so the collar part 11a of the release button 11 will be Since it remains in the hole 18 of the slide plate 10 and is locked, the slide plate 10 does not slide backward. Therefore, in this state, even if the deck 5 is pressed, the connectors 7 and 8 cannot be connected to each other. Therefore, since the deck 5 cannot be connected by any method of insertion other than in a predetermined horizontal position, the connector can be attached and detached without destroying it.

Although one embodiment of the present invention has been described above, in addition to the above example, a structure in which the slide plate 10 slides up and down is also conceivable. Further, as for the clock holes 17 and 18 of the release button 11 of the slide plate 10, if a lock device is provided in the connectors 7 and 8, only one hole 18 and a slit for sliding are required.

Effects of the Invention As described above, the present invention is provided with a release button on the main body that releases the stopper only when the cordless handset is installed in a predetermined mounting direction, making it possible to connect the connector only from the predetermined horizontal direction. This is extremely advantageous in practice as it can eliminate damage to the connector.
