Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to electrical equipment with separate speaker boxes, such as cassette tape records with radio receivers and stereo equipment.

Conventional configurations and their problems In recent years, in electrical equipment such as cassette tape recorders with radio receivers and stereo equipment, the main body of the equipment housing the radio receiving circuit, stereo circuit, etc. and the speaker box housing the speakers have been separated. In recent years, it has become common to see devices in which these devices are formed and removably connected. However, in this type of conventional electrical equipment with separate speaker boxes, cords are used to electrically connect the main unit of the equipment and the speaker box, and it takes time and effort to connect and disconnect the cords, and the cord handling is extremely troublesome. I had a problem.

Purpose of the invention The present invention eliminates the above-mentioned conventional drawbacks, and provides an electrical device that can electrically connect the speaker box and the main body of the device at the same time as mechanically coupling the two. The purpose is to

Structure of the invention The electrical device of the invention has an engaging part provided on the side surface of the main body of the device and an engaging part provided on the side surface of the speaker box that are engaged with each other and are provided so as to be freely accessible from the side surface of the speaker box. The lock piece is configured such that the lock piece can be freely entered and exited from the side surface of the device body, and the lock piece is inserted into a through hole provided on the side surface of the device body and connected to both, and the connection terminal provided on the lock piece is The device is configured to be brought into contact with a connection terminal provided near a through hole in the device main body so as to supply an audio output signal from the device main body to the speaker on the speaker box side.

DESCRIPTION OF EMBODIMENTS FIGS. 1 to 3 show an embodiment of the present invention. In the figures, 1 is a device body consisting of a tape recorder with a radio receiver, and 2 is a device that can be attached or detached from both sides of the device body 1. It is a speaker box that can be freely installed.
As shown in FIG. 2, the device main body 1 has a plurality of engaging ribs 1-a integrally formed on the side surface of a cabinet constituting it, and also has a through hole 1-b. On the other hand, the speaker box 2 is the second
As shown in the figure, the side surface of the cabinet constituting the cabinet has an engaging groove 2-a into which the locking portions provided at both ends of the engaging rib 1-a are inserted, and the engaging groove 2-a is inserted into and exits from the side surface. It has a locking piece 3 that is flexible. The lock piece 3 is provided with a pair of connection terminals 4, 4. In addition, the above device body 1
As shown in FIG. 3, a printed wiring board 6 is housed in the cabinet constituting it, and a pair of connection terminals 5, 5 are provided in the printed wiring board 6 so as to correspond to the through holes 1-b. is installed. The printed wiring board 6 constitutes a radio receiving circuit or a telerecorder circuit, and the connecting terminals 5, 5 have spring contact pieces 5a, 5b facing each other so as to sandwich the lock piece 3, Electrical audio signals are taken out to the pair of connection terminals 5, 5.

Reference numeral 7 denotes a chassis installed inside the cabinet constituting the speaker box, and as shown in FIG. Connection terminal 10 for connecting with a cord
It has a mounting portion 7b. Then, insert the connecting terminals 4, 4 bent into a U-shape as shown in FIG.
The pair of connection terminals 4, 4 are attached by engaging them in the engagement holes 3a, 3a of the lock piece 3. Further, the lock piece 3 has a mounting hole 3b for a click coil spring 9, and a knob portion 3c. The speaker box 2 above is
First, the mounting hole 3 of the lock piece 3 with the connecting terminal 4 attached.
With the click coil spring 9 inserted into the coil spring 9 and the steel ball 8 disposed at the tip of the coil spring 9, the lock piece 3 is inserted into the groove 7a of the chassis 7.
Insert and install. Further, a connection terminal 10 is attached to the attachment portion 10 of the chassis 7. The chassis 7 prepared in this way is attached to the guide ribs 11 provided on the inner surface of the cabinet constituting the speaker box 2.
12 and tightening the screw 13 to the cabinet side, the connecting terminal 1 is inserted into each of the through holes 14 and 15 on the back side of the cabinet.
0. The lock piece 3 is assembled so that the knob portion 3c of the lock piece 3 protrudes and faces the through hole 16 in the side surface of the cabinet.

In an electrical device having such a configuration, the engagement groove 2-a provided on the side surface of the speaker box 2 is slid and fitted into the engagement rib 1-a provided on the side surface of the device main body 1. Knob portion 3c with lock piece 3 protruding from the back of the speaker box 2
By operating the lock piece 3 and fitting it into the through hole 1-b provided on the side surface of the device main body 1,
The device main body 1 and the speaker box 2 can be mechanically coupled. At this time, the lock piece 3 fitted in the through hole 1-b connects the pair of spring contact pieces 5a of the connection terminals 5, 5 provided in the device main body 1,
5b, the connection terminals 4, 4 sandwiched between the lock pieces 3 come into contact with the connection terminals 5, 5. Therefore, by coupling the connection terminals 4 and 5, the audio outputs of the radio receiving circuit and tape recorder circuit on the device main body 1 are electrically connected to the speaker in the speaker box 2.

Effects of the Invention As detailed above, according to the present invention, the engaging portion provided on the side surface of the device body and the engaging portion provided on the side surface of the speaker box are engaged with each other, and the engaging portion provided on the side surface of the speaker box is engaged with each other. A lock piece provided so as to be able to come in and out from the device body is inserted into a through hole provided on the side of the device body to connect the two to each other, and a connecting terminal provided on the lock piece is provided near the through hole in the device body. Since the configuration is such that the audio output signal from the device main body is supplied to the speaker in the speaker box by contacting the connection terminal, the electrical connection to the speaker in the speaker box is simultaneously made when the device main body and the speaker box are connected. connection can be made. In addition, compared to conventional systems that use cords to electrically connect the device and the speaker box, there is no need to attach or disconnect the cords, and the cord handling is also easier, making it easier to use. has advantages.
