Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a back cover of an electric device and has an opening formed in a back wall.

[0002]

[Prior Art]

 Many cords, such as power cords, amplifier cords, and connection cords, are led out from the back of electrical equipment such as audio equipment and video equipment, and these cords are easy to cross and are unsightly. Therefore, as shown in FIG. 11, it is known to mount a back cover 102 on the back surface of the electric device 101 to prevent the cord 103 from being crossed.

[0003]

[Problems to be solved by the device]

 However, in the conventional back cover 102, since the cord 103 cannot be positioned, the cross-link cannot be completely eliminated, and the cord 103 is forcibly bent, which may cause disconnection or disconnection of the connector 104. Since the cord 103 is completely covered by the back cover 102, there is a problem that wiring mistakes and connection failure of the cord 103 cannot be confirmed unless the back cover 102 is removed. Therefore, an object of the present invention is to provide a back cover that solves the problems of the above conventional means.

[0004]

[Means for Solving the Problems]

 For this reason, the present invention has an opening 2 formed in the back wall 1b of the back cover 1.

[0005]

[Action]

 According to the above configuration, by exposing a part of the cord 4 from the opening 2, it is possible to position the cord 4 so as not to cause crosstalk. Also, by bending the cord 4 largely and exposing it in a curved shape in the opening 2, it is possible to prevent disconnection of the cord 4 and disconnection of the connector 3, and to confirm wiring mistakes and connection failure of the cord 4 from the opening 2. it can.

【Example】

 (Embodiment 1) Next, an embodiment of the present invention will be described with reference to the drawings. In FIG. 1, 10 is an electric device, and a back cover 1 is attached to the back surface thereof. The back cover 1 is composed of a horizontal upper wall 1a and a vertical back wall 1b, and a plurality of vertical length openings 2 are formed in the back wall 1b. Reference numeral 3 denotes a connector, which is mounted on the back surface of the electric device 10. The cord 4 led out of the connector 3 is largely bent and exposed from the opening 2. In this case, if the width of the aperture 2 is made substantially equal to the outer size of the cord 4, the cord 4 can be locked by a slight deformation of the cord 4 or the bending of the periphery of the aperture 2.

By thus locking the cord 4 in the opening 2, the cord 4 can be positioned and cross-linking can be prevented. Further, since the cord 4 can be greatly bent by forming the opening portion 2, it is possible to prevent the cord 4 from being unduly stressed and the cord 4 from breaking or the connector 3 from falling off. Further, since the inside can be seen through the opening 2, wiring mistakes and connection failures can be easily confirmed from the outside, and the opening 2 also serves as an escape hole for heat generated by the electric device 10.

Example 2 FIGS. 3 (a), 3 (b) and 3 (c) show a means for forming an opening. In FIG. 3 (a), 6 is a plate on which the product name of the code 4 (for example, AMP amplifier) is entered. The plate 6 has a locking claw 7, and the plate 6 is engaged with the opening 2 to close it during storage or transportation. When the back cover 1 is attached to the back surface of the electric device 10, the plate 6 is removed from the opening 2 and attached to the opening 8 formed near the opening 2.

In FIG. 3B, the opening 2 is closed by a cover plate 11. The cover body 11 is joined to the edge of the opening 2 by a strip 12. Therefore, when the back cover 1 is attached to the electric device 10, the strip 12 is cut off from the opening 2.

In FIG. 3C, the opening 2 has a tongue piece 13. When the cord 4 is thin, the cord 4 may be locked to the tongue piece 13. Further, when the tongue piece 13 is unnecessary, the tongue piece 13 may be cut off or may be bent inward of the back cover 1 as shown in the drawing.

Third Embodiment In FIGS. 4 and 5, the back cover 11 includes an upper wall 11a, a back wall 11b, and a lower wall 11c. The back wall 11b is provided with a plurality of vertically elongated openings 12, and the lower wall 11c is provided with an opening 19. Reference numeral 13 is a connector, and its cord 14 is led out from the opening 19. In FIG. 6, reference numeral 15 is a stopper for preventing the back cover 11 from falling off, which is an electrically insulating rod body 15a having stoppers 15b and screw portions 15c at the front and rear ends, and a screw portion. It is composed of a washer 15d screwed to 15c and a nut 15e.

As shown in FIG. 5, the rod 15a is inserted into the opening 12, the tip 15f thereof is inserted into the unnecessary connector 16 on the electric device 10 side, and the back wall 11b is fixed by the washer 15d and the nut 15e. Attach to. Thus, the opening 12 of the back wall 11b can be used as a mounting means for the stopper 15. In this case, since the opening 12 is a long hole, the stopper 15 can be mounted at any height according to the height of the connector 16 as shown in FIG.

FIG. 7 shows another embodiment of the stopper 17. This stopper 17 has the same structure as the stopper 15 described above, except that the rod-shaped 17a is formed of a conductive metal, and a hole 17g as a mounting portion of the connector 13 is formed on the rear end surface thereof. There is. 17b is a stopper, 17c is a threaded portion, 17d is a washer, and 17e is a nut.

The stopper 17 is attached to the back wall 11b of the back cover 11 in the same manner as the stopper 15 described above, and the connector 17 is attached to the hole 17g on the rear end surface of the screw portion 17c protruding outward from the back wall 11b. By inserting the pin 18 protruding from the connector 13, the connector 16 and the connector 13 are electrically connected via the stopper 17. This stopper 17 is useful when cords are connected to all the connectors 16 of the electric device 10 and there is no vacant connector 16.

Fourth Embodiment In FIGS. 9 and 10, the back cover 21 is composed of a bellows-like expandable side wall 21 a and a back wall 21 b, and the back wall 21 b has openings 22 arranged in a matrix. A plurality of them are formed. A stopper 23 includes a rod 23a, an engaging claw 23b provided at the tip thereof, a screw portion 23c provided at the rear portion thereof, and a nut 23d screwed to the screw portion 23. , The engaging claw 23e attached to the nut 23d.

As shown in FIG. 10, the back cover 21 is attached to the back surface of the electric device 10 by the stoppers 23. The back cover 21 is attached to the back surface of the electric device 10 according to the clearance between the back surface of the electric device 10 and the wall in the room. The depth L of the back cover 21 can be adjusted by screwing 23. Reference numeral 24 is a connector, and 25 is a cord.
