Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises components such as a cassette deck unit, an FM tuner/timer unit, an amplifier/equalizer unit, and a digital player unit, which are interconnected and connected to a power source. The present invention relates to a unit-type stereo Hi-Fi device that is connected to a remote connection unit such as a unit or a speaker unit.

In known stereo Hi-Fi devices, the various components form individually energized units, which are arranged left and right and/or above and below, and are connected to each other by connection lines, and also by connections separated from them. connected to the unit.

A disadvantage of this known device is that the wiring of the device cannot be done by an amateur. Moreover, this wiring must be rearranged when the device is expanded by attaching one or more other units. Therefore, an object of the present invention is to provide a system that allows anyone, even an amateur, to assemble a device, and in which connection between the necessary components and a remote connection unit can be completed simply by assembling the components into the device. The purpose of the present invention is to provide a stereo Hi-Fi device of the same type.

This problem is solved as follows.

That is, the components are integrally formed into shallow, flat, rectangular assembled units of equal height and length and capable of being fixed adjacently on at least one lateral coupling rail; Connections between the connecting elements of the assembled unit and with the connecting unit are made via the connecting rail. When assembling the device,
The user simply has to place the components, which are formed as assembled units, on the coupling rail. By pre-wiring the coupling rails and the connecting elements, the wiring of the device is almost completely arranged in advance, thereby eliminating the possibility of erroneous connections. According to an embodiment of the invention, the rear side of the assembled unit is provided with a lateral insertion groove for the restrictive insertion of the coupling rail.

This allows the assembled unit to be placed on a flat installation surface,
Can be mounted on a flat wall. The electrical connection between the assembly unit and the coupling rail is made, for example, as follows.

That is, the assembly unit and the coupling rail are interconnected by plugs and sockets as connecting elements. In this case, the plug is arranged in the groove of the assembly unit and the socket is embedded in the coupling rail so as not to affect the integral fitting of the coupling rail into the insertion groove of the assembly unit. The assembled units fitted together in this manner constitute one unit together with the connecting rails. To make the unit easier to handle, another embodiment includes a
the height and length are equal to the height and length of the assembled unit;
Attach a gripping edge with a gripping recess formed on the outside. The mechanical retention of the assembled unit on the coupling rail is improved by embodiments of the invention in the following manner.

That is, a hole for the fixing member is additionally provided in the coupling rail, and an insertion hole for the fixing member is provided in the insertion groove of the assembly unit, so that the assembly unit and the coupling rail are mechanically connected. do. This fixing member may be a screw, a bayonet, or the like. The addition of several assembly units to the device is also facilitated by the invention.

That is, the combined rail is assembled from partial rails,
In this case, multi-pole plugs and multi-pole sockets provided on the end faces of the partial rails are used to terminate the connection lines. It should be noted that when constructing the ends of the device, consideration must be given to the treatment of plugs and sockets as well as the connecting wires.

The number of connecting wires depends on the total number of connecting wires required between two or more assembled units and on the number of connecting wires led from the assembled units to the connecting units. The mechanical connection between the partial rails is improved according to an embodiment of the invention as follows.

That is, guide members such as a guide rod and a guide hole are provided in the connecting region of the partial line and are fitted together so that the guide rod is locked in the guide hole. For locking, a simple method is to use a set screw or the like. According to a further embodiment, the mechanical and electrical connections between the assembly unit and the coupling rail can also be made as follows.

That is, by using an assembly unit with two insertion grooves and two coupling rails, one coupling rail performs the mechanical connection between the assembly unit and the coupling rail, and the other coupling rail connects the multipole plug and socket together. This is used to make electrical connections between assembled units and with connected units.
In this way, it is possible to provide a plug device with a sufficient number of poles even if the width of the coupling rail and assembly unit is narrow. According to yet another embodiment, the number of poles of the plug device can be increased as follows.

That is, by using an assembly unit with two fitting grooves and two coupling rails, the electrical connection between the assembly units is made via one coupling rail, and the connection between the assembly unit and the connection unit is made by using the other coupling rail. Further, the mechanical connection between the assembled units is provided via one or both coupling rails. This configuration allows electrical connections to be made through both coupling rails. The arrangement of the assembly units on the combined rails is such that the width of the assembly units is equal, the multi-pole plugs of the assembly units are placed in equal positions in the grooves, the length of the partial rails is matched to the width of the assembly unit, and the width of the assembly units is made equal. The arrangement of the sockets in the rail can be freely selected by matching the arrangement of the plugs in the assembly unit.

In this case, too, the electrical connections run over the entire length of the combined rail (integral or composite of partial rails), depending on the type of multi-core busbar. Even when the assembled unit and the plugs and sockets of the combined rail or partial rail are arranged in different ways, the wiring of the assembled unit can be reliably and automatically done just by assembling the device.

Due to the shallow and flat design of the assembly unit, the entire device can also be mounted on a wall.

For this purpose, holes for wall mounting can be additionally provided in the connecting rail or partial rail. Next, embodiments of the present invention will be described in detail using schematic drawings.

FIG. 1 shows the stereo Hi-Fi device of the present invention, which consists of four assembly units and two undivided coupling rails.
The figure is a diagram schematically showing the connection between the assembly unit and the connecting rail,
FIG. 3 shows an embodiment for a coupled line formed by joining partial rails.

Figure 1 shows four shallow, flat, rectangular assembly units 1.
0.1 to 10.4 are shown.

The height, width and length of these assembly units are equal to each other, and on the back side two transverse insertion grooves 27.2 are provided for the restrictive insertion of the two coupling rails 20. The assembly unit 10.1 has a tape insertion opening 12, a digital display surface 11 and various adjustment devices 13, 15, 19.
This is a case deck unit equipped with the following. The assembly unit 10.2 is an FM tuner/timer unit and comprises, in addition to adjustment devices 15, 19 and a digital display surface 11, a keyboard 14 and a key row 18.

The assembly unit 10.3 is an amplifier/equalizer unit and comprises adjustment devices 13, 14, 15, 16 and a digital display surface 11. The assembly unit 10.4 is a digital player unit and comprises a disk insert 17, adjustment devices 13, 14, 15, 19 and a digital display surface 11. A gripping part 30 is attached to each end of both coupling rails 20, which gripping part is adapted in height and length to that of the assembled unit and has a gripping recess 31 formed on the outside.

4 are fixed in parallel on the coupling rail 20, which is fitted in a constraining manner into the insertion groove 27.2 of the assembly unit.

A connecting element is provided in the area of the insertion groove 27.2, so that the assembly unit is electrically connected to the coupling rail 20. The coupling rail 20 essentially has a multi-core busbar which runs over the entire length of the coupling rail. In this way, the assembled units are connected to each other and to the connecting units by connecting lines 34 led out from the coupling rail 20.
This connection is formed upon attachment of the connecting member to the assembly unit. The number of connection lines is determined by the number required for connections between assembly units and for leading to further connection lines.
This connection line may be routed via one of the two coupling rails 20. It is equally important to ensure that the assembly units 10.1-10.4 are held sufficiently firmly on the coupling rails. As shown in the diagram in FIG.

The partial rail 20.2 is inserted integrally into the insertion groove 27.4 of the assembly unit 10.4 and is not visible. A plug 26.4, which is attached to the assembly unit 10.4 in the insertion groove 27.4, is inserted into the socket 21.2. The socket 21.2 is provided in the partial rail 20.2. Since the partial rails can be formed into a uniform shape, the plugs 26.4 need only be placed equally in all assembled units 10.1 to 10.4.
The arrangement when assembling into a device can be freely selected. A gripper 30 is attached to the free end of the combined rail consisting of partial rails 20.1 and 20.2. This gripping part can be simply screwed onto the coupling rail 20 or the partial rails 20.1 and 20.2, as can be seen from the illustrated coupling position 32. A recessed space is formed on the outside of the grip portion 30, and a handle recess 31 is formed. Third
