Abstract

PROBLEM TO BE SOLVED: To provide a shielded box for measuring a portable telephone that can be manufactured easily and has a better shielding performance than a conventional one. SOLUTION: A shielded box consists of a box body 1 where a portable telephone 11 is placed in an electromagnetically shielded room 10 and a lid body 2 that is connected to the box body 1 so that it can be opened and closed freely. Channels 1A and 1B are provided around the electromagnetically shielded room 10 and a shielded wire 3 of an elastic body is buried. The shielded wire 3 of the elastic body is buried in a channel 2C of the lid body 2. When the lid body 2 is closed, each of projection parts 2A and 2B of the lid body 2 is brought into contact with the shielded wire 3 and a projection part 1C of the box body 1 is brought into contact with the shielded wire 3 of the channel 2C. The sheathing of the box body 1 and the lid body 2 can be formed in one piece by a light metal body, so that it can be manufactured easily. With the box body 1 being closed with the lid body 2, the projection part 2A orthogonally crosses a projection part 1D and the projection part 2B orthogonally crosses the projection part 1C, thus improving a shielding performance.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a shield box for measuring a mobile phone according to the present invention. In addition,
1, the description of the same reference numerals as in FIG. 3 is omitted.

In FIG. 1, 1 is a box, 2 is a lid, and 3 is a shield wire. The box 1 and the lid 2 constitute a shield box.

The box 1 is provided with an electromagnetic shielding room 10 whose upper surface is open. The electromagnetic shielding room 10 has a box shape as shown in the figure, and has a sufficient volume for easily mounting the mobile phone 11. The lid 2 is connected to the box 1 so as to be openable and closable.

A hook 4A is attached to the outside front of the box 1. A stopper 5A is attached to the front outside of the lid 2, and a handle 5B is attached to the outside upper surface of the lid 2.

The portable telephone 11 is mounted in the electromagnetic shielding room 10, the handle 5B is grasped, the lid 2 is closed, and the hook 4A is engaged with the stopper 5A.

An elastic shield wire 3 is buried in a groove 2C formed by the projection 2A and the projection 2B of the lid 2. In FIG. 2, the protrusion 1C formed by the groove 1A and the groove 1B is arranged to face the groove 2C.

When the cover 2 of FIG. 2 is closed, the convex portions 2A and 2B of the cover 2
It contacts the shield wire 3 of B. Also, the convex portion 1C of the box 1
Contacts the shield wire 3 in the groove 2 </ b> C of the lid 2.

According to the present invention, the performance of the shield is ensured by the lid and the box being closely adhered by the elastic shield wire. In addition, the exterior of the box 1 and the lid 2 can be integrally formed of a lightweight metal body, which facilitates manufacture.

As shown in FIG. 2, when the lid 2 is closed in the box 1, the convex portion 1D formed by the electromagnetic shielding chamber 10 and the groove 1A and the convex portion 2A of the lid 2 are They are crossing. Furthermore, the convex portion 2B of the lid 2 and the convex portion 1C of the box 1 intersect.

That is, as is apparent from FIG. 2, the groove is provided in triple, the convex portion is provided in triple, and the groove and the convex portion have a closed structure in which the groove and the convex portion cross each other, so that the performance of the shield is improved as compared with the conventional case. .

[0023]

According to the present invention, there is provided a shield box comprising a box on which a mobile phone is placed in an electromagnetic shielding room, and a lid which is openably and closably coupled to the box. Providing a first groove, providing a second groove on the outer periphery of the first groove,
An elastic shield wire is buried in the first groove and the second groove, and the first convex portion and the second convex portion are formed on the cover so as to face the first groove and the second groove, respectively. Then, an elastic shield wire is buried in the third groove formed by the first protrusion and the second protrusion, and the third protrusion formed by the first groove and the second groove is formed. It faces the third groove.

Then, when the lid is closed, each of the first convex portion and the second convex portion comes into contact with the shield wire of the first groove and the second groove, and the third convex portion becomes the third convex portion. Since the shield wire is in contact with the shield wire of the groove, a shield box that is lightweight and easy to manufacture can be provided without lowering the performance of the shield.

Further, a fourth convex portion is formed by the electromagnetic shielding chamber and the first groove. When the lid is closed in the box, the first convex portion and the fourth convex portion intersect, and the fourth convex portion intersects. Since the second convex portion and the third convex portion intersect, there is an effect that the performance of the shield is improved as compared with the related art.
