Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a remote control light receiving section that can be used in television receivers and the like.

Conventional technology Recent years. With the shift to electronic channel selection, the demand for remote control transmitters that can be operated at hand has increased, and these devices have come to occupy a significant proportion of television receivers.

Hereinafter, an example of a remote control light receiving section that receives light emitted from the conventional remote control transmitter described above will be described with reference to the drawings.

Figure 6 is a perspective view of a conventional remote control light receiving section;
FIG. 8 is a perspective view of the shield case body, FIG. 8 is a perspective view of the shield case lid, FIG. 9 is a perspective view of the printed board, and FIG. 10 is a cross-sectional view.

In FIGS. 6 to 9, 16 is a front molded product, and a cut-out portion 1 protrudes from the shield case body 17.
8 fits into the hole 19 of the front molded product 16, thereby fixing the two. Reference numeral 20 denotes a lid of the shield case body, in which a convex dowel 22 protruding inward from the lid 20 is fitted into a hole 21 of the shield case body 17, and in order to securely fix the shield case body 1.
7 and the lid 20 are soldered 23.
Reference numeral 24 denotes a printed board, and the printed board 24 is scissor-fitted with a protrusion 25 provided at the bottom of the main body 17, and a notch 26 of the printed board 24 is inserted into the rear protrusion 29 to prevent rearward escape. Fix it. 27 attached to the printed board 24 is a connection coupler, and 28 is a light receiving diode.

10 is a sectional view, 20 is a lid, 17 is a shield case body, 25 is a protrusion protruding from the shield body 17, 24 is a printed board inserted into the protrusion 25, and 22 is a hole in the shield case body 17. 21 and is a convex dowel that protrudes from the lid 20.

Problems to be solved by the invention However, with the above configuration, a shield case body and a lid are required, and the holes and dowels alone are not stable enough to fix the lid to the shield case body, and soldering is required. The problem was that it required attachment.

The present invention solves the above problems by providing a slit hole in the shield case body, integrating the lid with the shield case body, and fitting the projection protruding from the shield case body with the hole in the lid. To easily fix a case body and a lid as one body, and to provide the case at low cost.

Means for Solving the Problems In order to solve the above problems, the remote control light receiving section of the present invention is made by bending a thin plate into a box shape so that the bottom is open, and integrating the bottom and one side. A shield case that has a slit hole in a joint on a side surface, a protrusion on a side surface opposing the side surface, and a hole that fits with the protrusion on the bottom; and a print housed in the shield case. The shield case has a plate, and the printed board is held between a plurality of upper parts of the printed boards provided inside the shield case and a plurality of legs provided at the bottom.

Function The present invention uses the above-described configuration to hold the printed circuit board inside the box-shaped shield case from the front.
Several protrusions are provided from the left and right sides, and the upper part of the printed board rests against the upper part.

To attach it to the lower part, provide a bent part on the bottom lid and fix it at the end surface. To prevent the printed board from moving, use the front part to apply it in the forward direction, and the rear part to apply it in the backward direction.

Further, the lid is fixed by fitting a protrusion protruding from the left side surface into a hole in the rising portion of the lid.

Then, the claws protruding from the panel or the like are fitted into the holes in the front molded product and fixed.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a remote control light receiving section in an embodiment of the present invention. In FIG. 1, 1 is a shield case main body, 2 is a front molded product, and 3 is a printed board.

Figure 2 shows the box-shaped shield case body 1.
4 is a light-receiving part square hole, and 5 is a support for the upper part of the printed board 3, which protrudes toward the inside of the shield case main body 1 from the front, left and right wall surfaces. 6 is a cut-and-raised part for attaching the front molded product 2; 7 is a bottom part that is integrated with the shield case body 1; a square hole 9 is provided in the rising part 8 of this bottom part 7; Protrusion 1
It is bent to fit and fixed at 0. 11
Reference numeral 12 denotes a leg that serves as a rest for the lower part of the printed board 3, and a leg 12 that also serves as a soldering part that requires electrical connection with the lower part of the printed board 3.

Figure 3 shows the printed board 3 on the shield case body 1.
FIG. 2 is a perspective view of the shield case body 1 being inserted from below and the bottom portion 7 integrally formed with the shield case body 1 being bent.

Several slit holes 13 are provided at the joint between the shield case body 1 and the bottom part 7, and key wires are inserted inside to make it easier to bend. When the printed board 3 is inserted, a rest 5 on the upper part of the printed board serves as a rest, and when the bottom part 7 is bent, the legs 11 and 12 serve as a rest on the lower part, sandwiching the printed board 3, and its movement is eliminated. To escape to the rear, electrical connection is required at the legs 12, so soldering is performed. 14 is a coupler for connection. FIG. 4 is a sectional view showing a state in which the main body 1 is formed into a box shape, and a hole 9 in a rising portion 8 of the bottom portion 7 is fitted and fixed to a protrusion 10 protruding from the main body 1. FIG. 5 shows a state in which the light receiving section is fitted and fixed by the panel claw 15 extending from the panel.

Effects of the invention As described above, according to the invention, the bottom part is formed integrally with the shield case body, and after inserting the printed board, the bottom part can be easily bent and fitted. Since it is integrated, there is no problem and it can be provided at low cost.

Conventionally, the shield case body and lid were constructed separately, and soldering was required to ensure that they fit together and were securely attached to the shield surface, and the number of parts was large, which was a factor in increasing costs. Since the present invention can solve the above problems, it has great practical effects.
