The housing 1 having a shield structure shown in FIG. 1 has a shield structure in which a sheet metal chassis 2 on which a high-frequency device (not shown) is mounted is covered with a cover 3 to block external radiation noise. Chassis 2
Is provided with a bottom plate 2a and a flanged side plate 2b, and the top opening is covered by attaching a cover 3 having a top plate 3a and a side plate 3b. The flange portion 2c connected to the upper edge of the side plate 2b of the chassis 2 supports the vicinity of the side edge of the top plate 3a of the cover 3, and the vicinity of the lower end of the side plate 3b falling from the side edge. A predetermined position is fixed to the side plate 2b on the chassis 2 side by a fixing screw 4. In the case of this example, a seat portion for receiving the screw head is recessed so that the screw head of the fixing screw 4 does not protrude from the side plate portion 2b, and the depth of the recess is set between the opposing surfaces of the side plate portions 2b and 3b. A gap is formed.

定維持が困難である等の課題を抱えるものであった。In the above-mentioned conventional shield structure housing 1, a seat portion for the fixing screw 4 and a top plate 3a received by the flange portion 2c serve as an electrical connection between the chassis 2 and the cover 3, and the flange portion 2c This gives the impression that the top plate 3a in contact with the surface greatly contributes to securing the conduction area. However, in actuality, the conduction effect as imagined cannot be obtained due to the limitation of the processing accuracy of the cover 3 itself and the distortion of the cover 3 caused at the time of assembling. 2 and the cover 3 are close to a point contact, and it is difficult to stably maintain the shielding effect.

The lower edge portion is fixed to the flange portion 2c, and the upper surface portion supported by the lower edge portion pushes up the top plate portion 3a from below with elasticity. That is, the conductive spring washer 6 is provided between the flange 2c of the chassis 2 and the top plate 3a of the cover 3 and functions as a conductive material.

の課題を抱えるものであった。The above-mentioned conventional shield-structured housing 5 requires that a conductive material such as a conductive spring washer 6 or conductive rubber be interposed between the chassis 2 and the cover 3. In addition to the work of screwing in, a work of inserting a conductive material is required, and the number of steps of the entire assembling work is increased, so that there is a problem that it cannot be easily manufactured.
Further, the conductive material such as the conductive spring washer 6 and the conductive rubber may be seen through a heat radiating hole (not shown) provided in the cover 3 or the chassis 2, and the fixing screw 4 whose head appears to be exposed. Similar to the above, there were problems such that the more the places used, the more easily the aesthetic appearance was spoiled.

る。The cover 13 is provided on the bottom plate 1 of the chassis 12.
It comprises a top plate 13a that covers 2a, and a pair of left and right side plates 13b that are bent at substantially right angles on both sides of the top plate 13a and fall. The chassis 1 is provided on the side plate 13b.
The cut-and-raised portions 16 for making electrical contact with the chassis 2 are formed in rows at regular intervals, and the chassis 1 is provided at two lower ends.
The tongue portion 17 that engages with the second engagement hole 15 is curved and provided. The cut and raised portion 16 is formed by being cut and raised so as to protrude inward from the side plate portion 13b when the cover 13 is formed by a mold, and is curved in a semi-cylindrical shape as shown in FIG. I have. The tongue 17 is formed by bending a part of an elastic piece defined between two parallel cuts extending from the end of the side plate 13b into a U-shape. A lock hole 17a is formed in the lock hole 17a. 4 indicates the shape of the lower end portion of the elastic piece before the tongue portion 15 is curvedly formed, and the elastic piece before the molding extends below the lower edge of the chassis 12. In addition, the heat radiation holes 18 which form a line at equal intervals are also formed in the side plate 13 b of the chassis 13, and communicate with the heat radiation holes 15 on the chassis 12 side after assembly to form a heat radiation path.

して導通状態すなわちシールド状態となる。When assembling the cover 13 to the chassis 12, first, the top plate 13a of the cover 13 is held directly above the bottom plate 12a of the chassis 12 so as to face the lower surface, and the lower cover 13 is attached while maintaining the posture. . In this case, the cover 13 slides down the inner surface of the side plate 13 b along the outer surface of the side plate 12 b of the chassis 12. When the lowering of the cover 13 approaches the lowering limit, the tongue 17 enters the engaging hole 15, and the claw 15 of the engaging hole 15 is inserted into the locking hole 17 a of the tongue 17.
a locks. Thus, the assembly of the cover 13 to the chassis 12 is completed, and the shield structure housing 11 is completed. In the completed shield structure housing 11, the cut-and-raised portion 16 of the cover 13 comes into contact with the side plate portion 12b of the chassis 12, and the chassis 12 and the cover 13 are electrically connected to each other to be in a conductive state, that is, a shield state.

れる。Further, since the tongue 17 is elastically connected to the cover 13 because of its molded shape, the side plate 13b of the cover 13 is moved to the side plate 12b of the chassis 12 at the time of engagement with the engagement hole 15. It is biased in the approaching direction. On the other hand, the cut-and-raised portion 16 projecting inward from the side plate portion 13b of the cover 13 abuts against the side plate portion 12b of the chassis 12 with resiliency, so that the cover 13 is firmly secured to the chassis 12 without play. Assembled in That is, although the fixing screw 4 and the like are not used at all, the strength of assembling the cover 13 with respect to the chassis 12 can be sufficiently ensured.
The electrical continuity between 3 and chassis 12 is stably maintained.

For a box-shaped chassis having a bottom plate and a side plate, and at least a part of the top surface is open, a cover having a top plate and a side plate is covered with the top surface opening of the chassis and the side plates of each other are connected to each other. When assembling them in such a manner that the claws are left on the inner peripheral edge, the tongues that are curved and project from the side wall of the cover to the inner wall are engaged with the engagement holes formed in the side wall of the chassis. The tongue is locked in the locking hole of the tongue so that the tongue does not come off the tongue, and the cut-and-raised portion formed on the side wall of the cover is formed on the inner wall side. And the cover and the chassis are electrically connected to each other. For this reason, the cover can be assembled to the chassis only by engaging the tongue of the cover with the engagement hole of the chassis, and since no fixing screws or springs are required, the assembly is very easy and the appearance is improved. The cut-and-raised part elastically abuts the outer wall of the side plate of the chassis without compromising the aesthetic appearance, so that the cover and the chassis can be securely electrically connected to each other, and the two are conductive. Excellent effects such as stabilization of the shield effect maintained by being in the state are exhibited.
