Description

[Detailed Description of the Invention] The present invention relates to a support for detachably attaching a speaker to a wall or the like.

Currently, for example, various buildings such as department stores and stations are equipped with broadcasting systems for broadcasting guidance and the like, and speakers are installed at the end of the system in each room and other places.

Conventional speakers have the disadvantage that both wiring work and speaker mounting work must be done in order to mount the speaker on a wall or the like, making the mounting process complicated and inconvenient.

Therefore, in order to eliminate the above-mentioned drawbacks, a protrusion is provided on the outlet body that is attached to a wall, etc., a plurality of insertion grooves are provided in the upper part of the protrusion, and the electrode holder is connected to the terminal in each insertion groove. The loudspeaker has a fitting hole on the back or side surface thereof, a plurality of hanging electrode terminals are provided in the fitting hole, and a plurality of hanging electrode terminals are provided below the electrode terminals of the fitting hole. A loudspeaker support comprising a connector having a lower space into which a protrusion can be fitted, the outlet and the connector being removably connected, and the electrode holder being capable of connecting a terminal and an electrode terminal. is proposed.

However, in this proposed loudspeaker support, as shown in FIGS. 7 to 9, the insertion direction S of the connector b attached to the loudspeaker a is parallel to the wall surface d on which the electrical outlet C is attached. If it is, it may not be possible to connect connector B and outlet C, or damage may occur due to excessive force being applied when connecting and disconnecting.

That is, in the case of Fig. 7, the outlet C is located below the protrusion e on the wall d, making it difficult to install, and in the case of Fig. 8, the outlet C is located within the recess f on the wall d. Therefore, it is difficult to install, and in the case of FIG. 9, the head of the screw g for attaching the electrical outlet lc protrudes, making it difficult to install.

In view of this, the object of the present invention is to provide a support that can easily connect an outlet and a connector even if the wall to which the loudspeaker is attached has unevenness, and that can also reliably support the loudspeaker. shall be.

EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention will be explained about an Example based on drawing.

In FIGS. 1 to 6, 1 is a connector attached to the rear panel A of the loudspeaker, and 11 is an outlet attached to the wall B.

The connector 1 and the outlet 11 constitute a loudspeaker support.

The connector 1 and the electrical outlet 11 are detachably connected, and the attachment/detachment direction S thereof is oblique to the wall B and the back plate A which is substantially parallel to the wall B.

Reference numeral 2 denotes a connector body made of synthetic resin, which is composed of a fitting recess 3 and a mounting piece 4 extending from the recess 3 in the left-right direction, and the mounting piece 4 can be attached to the back plate A of the loudspeaker with screws or the like.

Reference numeral 5 denotes a sliding surface formed on the bottom surface of the fitting recess 3, which regulates the insertion direction S of the connector 1 when the connector 1 and the outlet 11 are connected.

In addition, the upper surface of the fitting recess 3 is attached to the mounting piece 4 (back plate A of the loudspeaker).
) is orthogonal to

Reference numeral 6 denotes a knife-type electrode terminal, which includes a lead wire connecting terminal piece 6a, a mounting piece 6b, and a terminal piece 6C connected in this order.

When the electrode terminal 6 is attached to the connector body 2 with the screw 21, there is a gap approximately equal to the thickness of the protrusion 13 between the sliding surface 5 of the fitting recess 3 and the terminal piece 6C. , the terminal piece 6C is positioned substantially parallel to the sliding surface 5.

Further, a retaining hole 6d for positioning is bored in the terminal piece 6C.

Reference numeral 12 denotes an outlet main body made of synthetic resin, consisting of a protrusion 13 and a mounting portion 14 extending in the vertical direction of the protrusion 13;
The mounting portion 14 is attached to the wall B by screws or the like.

Reference numeral 15 denotes a guide surface formed on the front surface of the protrusion 13, which protrudes forward as it goes upward.

Reference numeral 16 indicates insertion holes (three in the drawing) formed in the L surface 18 of the protrusion 13, and a terminal 17 for the electrode holder is provided inside the insertion holes.

Further, the upper surface 18 of the protrusion 13 is perpendicular to the mounting portion 14 (wall B).

The terminal 17 of the electrode holder has a curved part 17a and a mounting part 17b.
and a locking portion 17C, and the attachment portion 17b is attached to the screw seat 19 of the outlet main body 12 with a screw 21.

17d is a projection formed on the curved portion 17a;
It is in contact with the guide surface 15 of.

The locking portion 17C is engaged with the engaging portion 20 of the outlet main body 12.

Next, the method for attaching the support will be described. First, the connector 1 (loudspeaker) is positioned diagonally above and in front of the outlet 11 attached to the wall B.

Next, insert the tip of the electrode terminal 6 (terminal piece 5c) into the insertion hole 1.
6, and press down in that state.

Then, the insertion direction S is regulated by the guide surface 15 of the protrusion 13 and the sliding surface 5 of the fitting recess 3, that is, the insertion direction is obliquely formed, and the outlet 11 and the connector 1 are connected. are fitted.

The connector 1 has a curved portion 17 in the retaining hole 6d of the terminal piece 6C.
It is inserted into the outlet 11 until the protrusion 17d of a is engaged, and both 6d and 17d are engaged, and the upper surface 5 of the fitting recess 3 comes into contact with the upper surface of the protrusion 13, and the outlet 11 and the connector 1 are connected.
The installation is completed.

Therefore, the connector 1 attached to the rear panel A of the loudspeaker
If it is connected to the outlet 11 attached to the wall body B, electrical connection can be made with one touch, and sufficient support strength can be obtained just by this connection.

In the above embodiment, the sliding surface 5 of the fitting recess 3 and the guide surface 15 of the protrusion 3 are curved surfaces, but they may be flat surfaces.

As described above, the present invention forms a guide surface on the protrusion of the outlet and a sliding surface on the fitting recess of the connector, making it possible to connect the connector to the outlet from an oblique direction. ) has excellent practical effects in that even if there are irregularities in the wall or the like to which the device is attached, the connection between the outlet and the connector can be made and the support can be performed reliably.
