Abstract

PURPOSE: To reduce the number of part items, and to facilitate assembling by integrally providing a wedge-like projection, which is formed of the inclined surface and the end surface, in a casing. CONSTITUTION: A resin casing 1 for holding an inlet part 2 is integrally provided with a fitting recessed part 3, in which an inlet part 2 in the holding condition is fitted, and a wedge-like projection 9, which is formed of the inclined surface 7 to be pushed by the inlet part 2 when the inlet part 2 is moved so as to be fitted in the recessed part 3 and the end surface 8 for hindering the movement of the inlet part 2 in the opposite direction in the condition that this inlet part 2 is moved to the holding position. Movement of the inlet part 2 in the opposite direction is hindered in the condition that the inlet part 2 is moved to the holding position by moving the inlet part 2 so as to be fitted in the recessed part 3, and the inlet part 2 is held in this condition.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holding structure for holding an AC power supply current inlet component in a resin casing such as a VTR.

[0002]

2. Description of the Related Art Generally, a structure shown in FIG. 2 is known as a structure for holding an AC power supply current inlet component in a casing such as a VTR (video tape recorder). In FIG. 2, (a) is an exploded perspective view before assembly, and (b) is a perspective view showing an assembled state. Reference numeral 1 is a resin case, and the vicinity of a portion related to the present invention is shown. The housing 1 holds the inlet part 2 while holding the inlet part 2.
Is provided with a fitting recess 3 into which is fitted and an opening 4 into which a connector (not shown) to be connected to the component 2 is inserted while the component 2 is held. Reference numeral 5 is a printed circuit board fixed to the inlet component 2, and 6 is a resin holder. When assembling the inlet component 2 into the housing 1, after fitting the component 2 having the substrate 5 into the fitting recess 3 as shown in FIG. 2B, the holder 6 is inserted into the fitting recess 3. Then, the hook portion of the holder 6 is fitted into the fitting groove (not shown) on the inner wall surface of the fitting recess 3.
In this state, the inlet component 2 is stopped by the holder 6 in the housing 1 and held in this state.

[0003]

The prior art requires a holder for stopping the inlet component as described above. Therefore, there are problems that the number of parts for holding is increased and assembly is complicated. In view of the above, it is an object of the present invention to provide an AC power supply current inlet component holding structure having a small number of components and easy to assemble.

[0004]

An AC power supply current inlet component holding structure of the present invention for solving the above problems and achieving the above object is provided in a resin casing of the electric device for holding the inlet components. , A fitting concave portion to which the inlet component in the holding state is fitted, a slope face pressed by this component when the inlet component is moved to fit the inlet component in the concave portion, and the component It is characterized in that it is provided with a wedge-shaped projection having an end face for preventing the component from moving in the opposite direction in the state of being moved to the holding position.

[0005]

In the AC power supply current inlet component holding structure of the present invention configured as described above, by moving the inlet component toward the fitting recess of the casing, the inlet component presses the protrusion. It is fitted in the fitting pushing portion, and in this fitted state, the end face of the projection prevents the inlet part from moving in the opposite direction, and is held in this state.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an AC power supply current inlet component holding structure for a VTR showing an embodiment of the present invention, and the same reference numerals as those in FIG. The resin casing 1 for holding the inlet component 2 has a fitting recess 3 into which the inlet component 2 in a held state is fitted, and the inlet 3 for fitting the inlet component 2 into the recess 3. A wedge-shaped projection composed of a slope 7 that is pressed by the component 2 when the component 2 is moved and an end surface 8 that prevents the component 2 from moving in the opposite direction when the component 2 is moved to the holding position. 9 and 9 are provided integrally. In the AC power supply current inlet component holding structure configured as described above, only the inlet component 2 is moved in order to fit the inlet component 2 into the recess 3 and the component is moved to the holding position. The movement of 2 in the opposite direction is blocked by the end face 8 and held in this state.

[0007]

As described above, according to the present invention, unlike the conventional one, the holder is not required, so that the number of parts is reduced and the assembling is facilitated.
