(Prior Art and Problems Thereof) There is an electronic device such as an audio device in the related art in which tuners, amplifiers, cassette decks, compact disc players, and the like are stacked vertically to construct a system. And when such electronic devices are stacked, in order to mechanically connect and fix the electronic devices together, for example, as shown in Utility Model Publication No. 44628 of 1983, each electronic device stacked with a bracket is screwed. It was fixed.

However, according to the above-mentioned conventional example, a special fixing tool such as a bracket is required for connecting and fixing. Further, there is a drawback that it takes a long time to perform the connecting and fixing work.

Further, in the conventional electronic devices used in a connected state, noise is reduced by using a ground wire or the like.

However, the conventional example using the above-described ground wire or the like is not sufficient in the case where accurate operation cannot be guaranteed unless the noise level of the computer device is lowered, and for that purpose it is necessary to stabilize the impedance between the electronic devices equally. there were.

The object of the present invention is to solve the above-mentioned drawbacks by simply connecting and fixing electronic devices without the need for a special fixture, and connecting electronic devices that can stabilize the impedance between electronic devices equally and reduce noise sufficiently. It is to provide a fixing mechanism.

(Means for Solving the Problems) In order to solve the above problems, a plurality of electronic devices each having a chassis equipped with an electronic circuit and the like covered by an exterior panel are placed or juxtaposed to each other and mechanically connected and fixed. In the mechanism, a protrusion and a grounding metal fitting are provided at one end edge of each side wall surface of the chassis facing each other in the electronic device connecting direction, and the other end edge of each side wall surface corresponds to the position of the protrusion. A pivotable lever metal fitting with a shaft center is provided, and when the electronic equipment is placed or arranged side by side, the external lever panel of one of the electronic equipment serves as an electronic equipment connection fixing surface. The lever-equipped metal fittings are locked to the protrusions of the other electronic equipment via the lever-equipped lever fitting insertion / extraction holes provided at the position where the electronic equipment is connected and fixed. The electrical continuity of an electronic device that is contacted and connected and fixed shall be enhanced.

Further, when the electronic device A is assembled with a cap, the external panel 1a is attached to the chassis 3a and then inserted through a circular hole (not shown) provided in the external panel 1a to be fitted with the shaft 6a. When A is connected and fixed to or disconnected from the electronic device B, a coin or the like is inserted into the groove indicated by 13a and rotated in the clockwise or counterclockwise direction to rotate the hooked lever metal fitting 4a. The hooked lever metal fittings 4a are rotatably provided at the lower center of the left and right side surfaces of the chassis 3a respectively, and similarly, the hooked lever metal fitting 4a is also shown at the lower center of the left and right side surfaces of the chassis indicated by 3b of the electronic device B. The metal fitting is rotatably provided. When the electronic device is not connected and fixed, the fitting piece 11a of the lock spring 7a is fitted into the lock hole 16a of the chassis 3a so that the lever metal fitting 4a with hook is housed in the electronic equipment A. Is positioned and fixed in the electronic device A.

Further, 12b in FIG. 1 is a cap of the electronic device B and is an exterior panel 1
The tip surface is located in the same plane as b to eliminate the protrusion from the exterior panel 1b. Similarly, the tip of the cap 12a is located in the same plane as the exterior panel 1a.

Next, 14a is a protrusion integrally formed in the center of the upper left and right side surfaces of the chassis 3a. Further, the protrusion 14a is for locking the electronic device having a similar connecting and fixing mechanism on the upper part of the electronic device A when the electronic device having the same connecting and fixing mechanism is mounted and fixed, when the hooked lever metal fitting of the electronic device mounted on the upper part is rotated. is there.

When rotated, this time it is fitted into the lock hole 16a and positioned and fixed.

In addition, the direction in which the groove 13a of the cap 12a is cut and the lever metal fitting with hook
Since the levers of 4a are coupled in the same direction, the hooked lever metal fitting 4a is locked to the projection 14b of the electronic device B when viewed from the direction of the groove 13a even from the outside of the electronic device A. Whether or not B is connected can be determined at a glance. Further, the cap 12b of the electronic device B and the hooked lever metal fitting (not shown) are also coupled in the same manner as above. Looking at the groove 13b of the cap 12b in FIG. You can see that it is stored in B.

Next, 17a is an earth metal fitting and is screwed and fixed near the protrusions 14a provided on the left and right side surfaces of the chassis 3a. This earth metal fitting 17a is used when the hooked lever metal fitting is locked to the protrusion 14a.
An inwardly protruding contact piece shown at 18a is brought into contact with a hooked lever metal fitting to enhance conduction. In FIG. 1, the hooked lever metal fitting 4a of the electronic device A is the protrusion of the electronic device B.

When inserting a coin or the like into the groove 13a of the cap 12a and turning it clockwise, the hook lever metal fitting 4a protrudes from the hook lever metal fitting lower surface insertion hole of the exterior panel 1a through the hook lever metal fitting upper surface insertion hole of the exterior panel 1b. The electronic device A and the electronic device B are easily connected and fixed by being locked to 14b.

Further, when releasing the coupling and fixing, it is only necessary to turn the cap 12a counterclockwise and store the hooked lever metal fitting 4a in the electronic device A. When the components are connected and fixed, both the electronic device A and the electronic device B are electrically connected, so that the impedance between the devices is equal and stable. Therefore, noise can be sufficiently reduced and the reliability of the device can be improved.

Further, by providing the projections and the hooked lever metal fittings on the chassis of the electronic device A and the electronic device B respectively, it is possible to stack and fix other electronic devices having a similar connecting and fixing mechanism.

Further, in the present embodiment, the first electronic device A was placed on the second electronic device B and connected and fixed, but it is obvious that the same electronic structure can be connected and fixed even if the upper and lower parts are interchanged, and the same mechanism is used.
