Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to electrical equipment, and more specifically, to an improvement of a terminal board for connecting external equipment that is attached to the back cover of an electrical equipment such as a cassette tape recorder.

Generally, in audio equipment such as a cassette tape recorder, various circuit boards, tape drive mechanisms, etc. are attached to a chassis that is inserted into a cabinet, and then the assembly is installed inside the cabinet. However, according to this method, in addition to requiring a chassis, it is also necessary to form mounting legs on the chassis or the board side, which does not make the work complicated and is not favorable in terms of cost.

This idea was created in view of the above-mentioned drawbacks of the conventional technology, and focused on a terminal board for connecting external equipment that is screwed onto the back cover of the cabinet. By providing a holding means, the purpose is to improve the workability of assembly/disassembly, etc., and to reduce costs.

Hereinafter, embodiments of this invention will be described with reference to the accompanying drawings.

FIG. 1 shows an example of an assembly of various interior boards using this terminal board 1 for connecting external equipment.
According to this, the terminal board 1 is provided with, for example, a record player connection connector 2, a grounding connector 3, etc. in a known manner, but in this embodiment, for example, two circuit boards 4, 5 are also provided. and a holding means for holding the support substrate 6 of the cassette tape drive mechanism. That is, this terminal plate is made of a metal plate that has been punched into a predetermined shape using a suitable processing machine such as a press machine and then bent, and has an L on one side for holding the circuit board 4 horizontally.
A side plate 8 having a flange 7 bent into a letter shape is provided in series. In this case, the circuit board 4 is screwed to the flange 7 via a heat sink 9 provided at its rear end, and on the other hand,
The bottom of the side plate 8 is a leg 12 which is supported on the bottom wall 11 of the cabinet 10 shown in FIG. Further, a notch 13 is provided approximately at the center of the upper side of the terminal board 1, and a claw piece 14 for holding the circuit board 5 in a vertical position is formed in this notch 13 by bending. ing. moreover,
The terminal plate 1 has a holding portion 15 in its lower portion for holding the support substrate 6 of the cassette tape drive mechanism. In this example, holding part 1
5 is formed in a concave shape, and a support substrate 6 is screwed to this portion. In this way, the circuit boards 4, 5, the support board 6 of the cassette tape drive mechanism, etc. are attached to the terminal board 1 as a substitute for the conventional chassis. The other end of .about.6 is held by the front panel 16. For example, since the circuit board 4 is provided with a rotary switch 17 for adjusting volume and balance, it is firmly attached to the front panel 16 via the switch 17. Further, the other circuit board 5 and support board 6 are similarly fixed to the front panel 16 via appropriate operating members.

Therefore, this terminal board 1, each internal board 4~
6, and front panel 16 may be set into cabinet 10, illustrated in FIG. 2, as one rigid assembly. Then, a predetermined portion of the front panel 16 is screwed to the front opening of the cabinet 10 using decorative screws or the like, and the back cover 18 of the cabinet 10 is placed on the back cover 1.
By screwing 8 and the terminal plate 1 together, the assembly is firmly fixed within the cabinet 10. Note that a female screw hole 19 for screwing the back cover 18 is provided in advance on the terminal board 1.

As is clear from the above description of the embodiment, according to this invention, the terminal board 1 for connecting external equipment has
Since it has the function of a conventional chassis that holds various internal circuit boards, it is easy to assemble and disassemble, and can significantly reduce costs, giving it great practical value.
