Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tuner device used in television receivers and the like.

In a tuner device using a variable capacitance diode as a tuning element, the open part of the tuner housing 1 is covered with a cover 2 as shown in FIG.
In general, a plurality of protrusions 3, 4 are formed on the tuner housing 1 by extrusion, and the engaging pieces 5, 6 of the cover 2 are engaged with the protrusions 3, 4.

FIGS. 2 and 3 show the engagement structure, in which the engagement piece 5 of the cover 2 is bent toward the housing 1 so as to engage with the protrusion 3 and abuts against the housing wall; Furthermore, it has a folded shape that separates it from there.

In such a structure, the engaging piece 5 can be inserted and engaged elastically, but since folding is required, dimension A in FIG. 2 needs to be increased to some extent. However, when this is applied to the surface 1a where the terminal 7 is present, there are restrictions due to the terminal 7, and the dimension A cannot be made large, so the folding of the engaging piece 5 must be made as small as possible. , this has the disadvantage that the engagement force becomes weak.

The present invention proposes a new and effective tuner device that is devised to avoid such drawbacks.

The present invention will be explained below according to embodiments shown in the drawings.

In FIG. 4, the terminal surface 1a of tuner housing 1
A cut-and-raised piece 8 is provided in the horizontal direction at the end of the cover 2. Correspondingly, nine of the engaging pieces 6 and 9 of the cover 2 are made short and small, and their tips are shaped like the housing as shown in FIG. It is made to face the body wall. The engagement between the cut and raised piece 8 and the engagement piece 9 is realized in a state as shown in FIG. In addition, it is possible to make do with the engagement means provided on the side of the casing 1 by using conventional extrusion protrusions 3 instead of the cut-and-raised pieces 8, but the protrusion dimension B
[See FIG. 2] There is a limit to the engagement, and good engagement cannot be expected in combination with the engagement piece 9.

In FIG. 4, the cover 2 is only shown in the case where it is attached to the upper open part of the tuner case 1, but a similar structure is used in the case of a tuner case that also has an open part at the bottom. It goes without saying that the cover 2, 2' should also be installed on the lower side, and FIG. 5 shows an example in which the covers 2, 2' are mounted on the upper and lower sides in this manner. Note that 8' is a lower cut-and-raised piece, and 9' is a corresponding engagement piece.

As explained above, the present invention has the effect of realizing firm cover engagement with a simple structure, and also provides a suitable effect in a relatively narrow space.
