Abstract

PURPOSE:To attach firmly a holding tool or the like with an easy work without screws by providing a projecting part in an attaching body of the holding tool which holds a degaussing coil of a television receiver and providing a recessed part, which has the diameter reduced toward the bottom part and to which a bar-shaped body is press-fitted, in the center part of this projecting part in the axial direction. CONSTITUTION:An attaching body 10 consisting of plastics is provided with the projecting part, and a recessed part 11 having a circular section which has the diameter increased slightly toward the open end is provided in the center part of this projecting part in the axial direction, and crossing cut grooves 12 are provided across the recessed part 11 to form four elastic holding pieces 13. In this constitution, individual holding pieces 13 are opened by the taper shape of the recessed part 11 when a bar-shaped body 16 is inserted to the recessed part 11. Then, individual projecting pieces 17 and 18 are inserted into cut grooves 12. Thus, a holding tool 14 is fixed between holding pieces 13. The tool 14 is fixed more firmly according as the tool 14 is pressed in.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for fixing a holder for holding a degaussing coil in, for example, a television receiver to a mounting body.

Structure of the conventional example and its problems As shown in Fig. 1, the conventional degaussing coil is held by wrapping and holding the coil 2 around a holding piece 1 made of a band-shaped metal body covered with an insulating tape. , "This holding piece 1 can be fixed to a boss 3 integrally provided on a mounting body (not shown) with screws 4, or the coil can be fixed with a holder 5 made of a resin molded product as shown in FIG. At the same time, the holder 5 was fixed to the boss 3 with screws 4 to secure the coil 2 to the mounting body.

However, in both methods, fixation to the mounting body is performed using screws, and each method has the disadvantage of poor workability.

OBJECTS OF THE INVENTION The present invention has been made to eliminate such conventional inconveniences, and it is an object of the present invention to provide a mounting device that can firmly mount a holder or the like with simple work without using screws.

Structure of the Invention In the present invention, a cylindrical rod-like body is provided protrudingly from an object to be attached such as a holder, and a first and second projecting piece and a joint portion with the rod-like body are formed on the outer peripheral surface of this rod-like body. The third type has a tapered surface whose width becomes wider as the width becomes narrowest. A fourth projecting piece is provided, and on the other hand, a projecting part is provided on the mounting body, and a recess is provided in the center of the projecting part, the diameter of which decreases in the axial direction toward the bottom, into which the rod-shaped body is press-fitted; Cut grooves into which the first to fourth projecting pieces are inserted and twisted are provided so as to cross the recessed portion.

Therefore, the holder etc. can be easily attached by simply inserting the rod-shaped body and the protruding piece into the recess and the groove.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 to 6.

FIG. 3 shows the overall structure, and FIGS. 4 and 6 show the main parts. In the figure, the mounting body 10 made of plastic or resin is provided with a protrusion, and in the axial direction of the center of the protrusion,
A recess 11 with a circular cross section whose diameter increases slightly toward the opening end is provided, and a cross-shaped cut groove 12 is provided across the recess 11 to form four elastic holding pieces 13. ing.

On the other hand, reference numeral 14 denotes a holder, which includes a holder 15 that can house and hold the coil 2, a rod-shaped body 16 integrally protruding from the lower surface of the holder 15, and a holder 16 protruding from the outer peripheral surface of the rod-shaped body 16 in opposite directions. A pair of protruding pieces 17°17 and this protruding piece 17. '1
A pair of protrusions 18 provided at positions rotated 90 degrees from 7,
Consists of 18. Here, the pair of protrusions 18, 18 are wedge-shaped, as shown in detail in FIG. On the other hand, the plate thickness of the other protruding pieces 17, 17 is constant throughout.

In the above configuration, as the base rod-shaped body 16 is inserted into the recess 11 as shown in FIG. 6, each holding piece 13 expands due to the tapered shape of the four parts 11.

Then, each protruding piece 17', 18 enters the cut groove 12.

At this time, as the rod-shaped body 16 is press-fitted, each retainer 1
3 widens, but since the protrusions 18, 18 have tapered surfaces 19, the end surfaces of each holding piece 13 come into pressure contact with the tapered surfaces 19 of the protrusions 18, 18. Thereby, the holder 14 is fixed between the respective holding pieces 130. This fixation becomes firmer and stronger as the holder 14 is pushed in.

Effects of the Invention As is clear from the embodiments, according to the present invention, the holder can be attached by simply pushing the holder between the holding pieces, resulting in extremely high workability.
