要となる。In recent years, in various terminal devices and OA equipment, resin materials such as engineering plastics are often used for housings because of requirements for decorativeness, weight reduction, heat resistance and the like. Since it is desirable to use a transparent resin for the display part and a resin with high heat resistance for the other case parts, a method for joining resin cases that integrates and joins different resins with high strength is required. ..

Description of the Related Art When assembling a resin housing, a transparent resin such as an acrylic resin is used for a display portion having a built-in LCD and the like, and the other housing portion is thin-walled so that it has good moldability and high heat resistance. Resins such as polyether sulfone (PES) and polycarbonate (PC) are used to join them by ultrasonic welding or the like to form a resin casing. Further, a resin having high rigidity is used for a screw portion that requires screwing.

方法が必要とされる。When a housing is formed by using various kinds of resin materials as described above, there is a problem as to how to bond the respective resins. For example, in joining a transparent acrylic resin plate used for a display part and a PES casing, the heat deformation temperatures of the two are extremely different (acrylic resin: 100 ° C. or lower, PES: 200 ° C. or higher),
When the conventional ultrasonic welding method is adopted, there is a problem that only the acrylic resin is melted and a sufficient bonding strength cannot be obtained. Further, in a device that requires a shield layer on the entire inner surface of the housing, a joining method is required so that the shield layers can be completely connected between the upper and lower housings.

It is to provide a joining method.

一体化された樹脂中間体に超音波溶着により接合する。[MEANS FOR SOLVING THE PROBLEMS] A resin intermediate body having a heat deformation temperature intermediate between two kinds of resins having extremely different heat deformation temperatures to be joined to each other is integrally formed on one of the resins to be joined by double molding. Turn into. Then, the other resin is bonded to the integrated resin intermediate body by ultrasonic welding.

して接合不良となることを防止することができる。Since the resin intermediate body integrated with one resin has an intermediate heat distortion temperature of the two kinds of resins to be joined, the other resin to be joined with the resin intermediate body is ultrasonically welded. It can be melted at the same time, and high joint strength can be obtained. As a result, it is possible to prevent only the resin on one side to be joined from melting and resulting in a joining failure.

突起６ａが一体的に形成されている。Referring to FIG. 2, there is shown an enlarged sectional view of a portion A of FIG. 1, in which the casing 2 made of polyethersulfone has a thickness t of 1 mm or less. A resin intermediate 6 made of polycarbonate is integrated with the housing 2 by double molding. The heat deformation temperature of the polyether sulfone, which is the material of the housing 2, is 200 ° C. or higher, and the heat deformation temperature of the acrylic resin, which is the material of the display unit 4, is about 90 ° C., but the resin intermediate 6 is made of polycarbonate. Since it is formed, its heat distortion temperature is about 150 ° C. which is intermediate between the two. In order to facilitate joining by ultrasonic welding to the resin intermediate 6,
The protrusion 6a is integrally formed.

着することができる。As described above, when the resin intermediate body 6 is integrally molded with the housing 2 and the display portion 4 is ultrasonically welded to the resin intermediate body 6, the heat deformation temperature of the display portion 4 and the resin intermediate body 6 becomes extremely high. Since there is no difference, the protrusion 6a of the resin intermediate 6 and the joint portion of the display unit 4 are melted at the same time, and the display unit 4 can be firmly ultrasonically welded to the housing 2.
