Description

[Detailed description of the invention] [Industrial application field] This invention is intended for use when installing a recording microphone for a remote control of a digital audio tape recorder called a DAT, for example, at the attachment point of an object to which the microphone is to be fastened. The present invention relates to a fastening device.

[Problems to be solved by conventional techniques and ideas]

Conventionally, comparative electronic devices had a protruding screw piece, and the object to be fastened was screwed onto this screw piece, so the object to be fastened was subject to vibrations from the outside due to repeated use of the electronic device. , a phenomenon often occurred in which they naturally relaxed and did not function efficiently.
Therefore, a technical problem arises that must be solved in order to overcome this defect.

[Means for solving problems]

This idea was proposed in view of the above-mentioned problems, and includes a screw piece protruding from one end of a case containing an electronic component, and a threaded piece in the middle of the screw piece. A recess is provided to interrupt the continuity of the parts, so that a C-ring can be fitted into the recess.
It is an object of the present invention to provide a fastening device for electronic equipment, characterized in that a ring nut is fastened to the screw piece, the C ring is fitted on the outside of the ring nut, and a body to be fastened is screwed on the outside of the C ring. It is something to do.

[Effect]

A double nut method is adopted in which multiple nuts are used to secure the object to be fastened to a screw piece that protrudes from one end of the case containing the electronic component, and approximately the middle part of the screw piece is used to secure the object to be fastened. is provided with a recessed portion that interrupts the thread continuity of the threaded piece. Therefore, first, when fastening the ring nut to the threaded piece, the ring nut is screwed into the threaded part at the inner part of the threaded piece from the recessed part. Then, C
Fit the ring. In such a case, the C-ring will lock onto the outer surface of the threaded ring nut. The object to be fastened, on which the ring nut is to be pressed against the outer surface of the C-ring, is screwed onto the threaded portion of the threaded piece on the outer side of the recessed portion. Therefore, the ring nut is locked to the C-ring, and the ring nut is restrained from rotating in the direction of the object to be fastened by the C-ring, and the object to be fastened is fixed at a fixed position. The object to be fastened does not loosen, and functions such as a recording microphone can be efficiently performed.

〔Example〕

An embodiment of this invention will be described below in detail with reference to the accompanying drawings. 1 is the DAT remote control. This remote control 1 is formed by joining together two halves of cases 1a and 1a to house various electronic components, and therefore a protrusion protrudes from one end of the joined cases 1a and 1a. The provided screw pieces 2, 2 are provided in two protruding shapes corresponding to the cases 1a, 1a, respectively, and are joined together. Thus, the joined screw pieces 2, 2
A recess 4 for fitting the C-ring 3 is provided approximately in the middle of the recess 4 . Therefore, the continuation of the threaded portions of the threaded pieces 2, 2 is interrupted by the recessed portion 4. Further, the depth of the recess 4 should not be particularly limited, but when the C ring 3 is fitted into the recess 4, the outer peripheral edge of the C ring 3 should be able to engage with the recess 5b. . 5 is a ring nut. This ring nut 5 has a threaded portion 5a on its inner surface so as to be screwed onto the threaded pieces 2, 2, and is screwed into the threaded portion at the inner part from the recess 4 of the threaded pieces 2, 2. . Furthermore, a fastened body 6 is screwed into the external male threaded part from the recessed part 4 of the threaded pieces 2, 2.
will be established. This fastened body 6 has a threaded portion 6a protruding from its tip, to which a microphone (not shown) is fastened to perform a recording operation. Further, the body 6 to be fastened is formed in the shape of a cap nut, and has a female screw portion provided on its inner surface to be screwed into the male screw portion of the screw pieces 2, 2.

In addition, the symbols 7, 7, . . . in the figure indicate operation buttons for switches.

One embodiment of this invention has the configuration described above, so cases 1a and 1a are joined together, and this case 1
Screw the ring nut 5 into the threaded pieces 2, 2 which protrude from one end of a, 1a and are to be joined, and then tighten the ring nut 5 from the recess 4 of the threaded pieces 2, 2 to the inner male threaded part. That's what I do. At this time, the outer surface of the ring nut 5 faces the upper surface of the inner part of the recess 4, and the C ring 3 is elastically deformed and fitted into the recess 4. Further, in order for the ring nut 5 to come into pressure contact with the outer surface of the C-ring 3, the fastened body 6 is screwed into the ends of the screw pieces 2, 2, and is then brought into pressure contact with the outer surface of the ring nut 5. .

In this way, the ring nut 5 and the fastened body 6 screwed onto the screw pieces 2, 2 are pressed together with the C-ring 3 fitted into the recess 4 of the screw pieces 2, 2 interposed therebetween. It is. Moreover, the ring nut 5 does not move toward the object to be fastened by the C-ring 3, and the object to be fastened is fixed to the screw piece 2, so that functions such as a recording microphone can be operated efficiently.

[Effect of idea]

In this invention, as described in detail in the above-mentioned embodiment, for example, the object to be fastened to which the recording microphone of a DAT remote control is attached is fastened to a screw piece protruding from one end of the case of the remote control. First, a ring nut is screwed onto the screw piece, and this ring nut is locked with the C-ring, so that the rotational moment in the direction of the object to be fastened is eliminated. It becomes almost semi-fixed, and the functions of microphones etc. that are connected to it are not obstructed.
