Abstract

(57) [Summary] [Structure] In an electronic device case, a divided case 3 having a concave groove 7 around the entire circumference of an engaging part, a rubber annular packing 11 having a metal plate 12 inside, and a packing 11 are used. A split housing 2 having an abutting portion 10 that presses the entire circumference of the engaging portion is provided. Insert the packing 11 into the concave groove 7 of the housing 3,
A feature is that the casing 2 is press-fitted into the casing 3. [Effect] It is possible to use a rubber packing made of a soft material that enhances the waterproof effect, and the installation work can be made easier without losing the shape of the packing.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention makes the housing of radio receivers, tape recorders, telephones, etc. waterproof (completely waterproof). It is applied to various electronic devices that require complete waterproofing, drip-proofing, and moisture-proofing.

0002

[Conventional technology]

Conventionally, commonly used electronic devices that require waterproofing have a divided housing. For example, a ring-shaped rubber gasket may be installed over one of the engaging parts of the front housing and the rear housing. the other housing part is inserted, and the gap between the two housing parts is eliminated and sealed. .

0003

[Problem that the idea aims to solve]

Current electronic device housings are becoming smaller and thinner, and due to the diversification of uses, they are becoming more sophisticated. High waterproofness is required. Therefore, the packing and the packing engagement part of the case are complicated. In addition, the annular packing is made of soft material to improve airtightness and is easy to install. This is worsening the efficiency of the industry.

0004

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention has been developed to solve the above-mentioned problems by providing a A divided housing A having a concave groove, and a metal plate inside and having approximately the same shape as the concave groove. Press the formed rubber annular packing and the rubber annular packing around the entire circumference of the engagement part. The rubber annular packing is attached to the housing A. The housing B is inserted into the concave groove of the housing A, and the housing B is press-fitted to the housing A. .

[0005]

[Effect]

Since the electronic device casing according to the present invention has the above-mentioned configuration, it can be miniaturized and The installation process involves inserting the annular packing all the way into the concave groove of the thin housing engagement part. It becomes easier. You can also choose a soft material for the rubber packing. It became so.

【Example】

Embodiments of the electronic device casing according to the present invention will be described below based on the drawings. As shown in FIG. 1, a housing 1 for a radio receiver, tape recorder, telephone, etc. For example, it is composed of a front housing part 2 and a back housing part 3 molded from ABS resin. The two housing parts 2 and 3 are fitted together.

[0007] Figure 2 is an exploded view of the housing 1, and Figure 3 is the housing at cross-section A and cross-section B in Figure 2. 1 is a schematic cross-sectional view of 1, and the case engaging part 4 of the rear case part 3 is covered from the inside over the entire circumference. The ribs 5 and 6 are integrally molded, and the ribs 5 and 6 form a concave groove 7 as shown in FIG. Ru. As shown in FIG. The joint rib 9 and the contact portion 10 are integrally molded.

[0008] The rubber annular packing 11 shown in FIG. 2 is inserted into the concave groove 7. In this case, it is molded from synthetic rubber, as shown in the cross-sectional view of FIG. 5 at the section C in FIG. At the same time, the metal plate 12 is insert-molded.

[0009] The rubber annular packing 11 has an oval cross section, and the lateral dimension (n) is The horizontal dimension (m) is approximately equal to the horizontal dimension of the concave groove 7 of the surface housing part 3, and the vertical dimension (m) is the concave groove 7. It is molded to be slightly larger than the vertical dimension.

0010 The metal plate 12 insert-molded into the rubber annular packing 11 is arranged around the entire circumference. The packing 11 may be inserted across the entire length or only partially in the longitudinal direction of the packing 11. Accordingly, deformation of the packing 11 can be prevented. Furthermore, the shape of the metal plate 12 is It is not limited to a plate shape, but may be a thin wire.

[0011] The front housing section 2 and the rear housing section 3 are engaged with each other via a rubber annular packing 11. In order to Insert the rubber annular packing 11, which has the same shape as the concave groove 7 and maintains its shape, and After that, by engaging the case engaging part 8 of the front case part 2 with the case engaging part 4, Then, the packing 11 slightly protruding from the concave groove 7 is pressed uniformly over the entire circumference by the contact part 10. The engaging rib 9 is pressed against the side surface of the rib 6 and is fitted. before if necessary By screwing the front housing part 2 and the back housing part 3, the mechanical strength of the fitting is increased. Of course, it is possible to do so.

0012

[Effect of the idea]

Since the electronic device casing according to the present invention has the above-mentioned configuration, it has an improved waterproof effect. Rubber packing made of soft material can be used, and it can be removed without changing the shape of the packing. The attachment work can be made easier.
