Here, Fig. 1 is an end view of an ultrasonic welding case according to an embodiment of the present invention, Fig. 2a is an end view showing the state at the start of ultrasonic welding, and Fig. 2b is the case before ultrasonic welding. FIG. 3A is an enlarged end view of the contact portion between the main body and the cap, FIG. 3A is an end view showing the state after ultrasonic welding, and FIG. 3B is an enlarged end view of the welded portion. Note that the present invention is not limited to the embodiments shown in the figures.

第１図において、超音波溶着ケース１は、熱可
塑性樹脂製ケース本体２と、熱可塑性樹脂製キヤ
ツプ３とからなつている。 In FIG. 1, an ultrasonic welding case 1 consists of a case body 2 made of thermoplastic resin and a cap 3 made of thermoplastic resin.

ケース本体２の側壁の上面２aと内面２bとが作
るコーナは、半径ｒで丸めた面２cとなつている。 The corner formed by the upper surface 2 a and the inner surface 2 b of the side wall of the case body 2 is a rounded surface 2 c with a radius r.

一方、上記上面２aに対応するキヤツプ３の下
面３aと、上記内面２bに対応するキヤツプ３の側
面３bとが作るコーナは、下面３aと角度θをなす
傾斜した面３cとなつている。 On the other hand, the corner formed by the lower surface 3a of the cap 3 corresponding to the upper surface 2a and the side surface 3b of the cap 3 corresponding to the inner surface 2b forms an inclined surface 3c which forms an angle θ with the lower surface 3a.

を生じている。 As shown in Figure 2a, when the electronic component P is housed in the case body 2 and the cap 3 is attached, the rounded surface 2c of the case body 2 and the inclined surface 3a of the cap 3 come into contact. . FIG. 2b shows an enlarged view of this abutting part, with gaps 5 and 6 on both sides of the abutting part between the rounded surface 2c and the inclined surface 3c .

定位置に保持する働きをする。 The bottom platform portion 3d of the cap 3 contributes to the positioning of the cap 3 with respect to the case body 2, and prevents displacement when ultrasonic vibration is applied. It also functions to press and hold the electronic component P housed in the case body 2 in a predetermined position.

され、外部にははみ出してこない。 As shown in FIG. 2a, when the horn H of the ultrasonic welder is pressed onto the cap 3, sliding friction is generated between the rounded surface 2c and the inclined surface 3c , which generates heat and melts. Due to sliding friction, the amount of heat generated is large and the melting area expands. Most of the melted resin is used to fill the gaps 5 and 6, and does not leak out.

かくして、第３図ａに示すように、ケース本体

がない。 Thus, as shown in FIG. 3a, the case body 2 and the cap 3 are welded together, and the welding strength and sealing properties are high and no burrs are produced.

り強固なものとなつている。 Figure 3b shows an enlarged view of the welded area.
Since only a small amount of melted resin enters between the upper surface 2 a of the side wall of the case body 2 and the lower surface 3 a of the cap 3 corresponding to the upper surface 2 a , dimensional accuracy after welding can be improved. Further, since the molten resin is also filled between the inner surface 2b of the case body 2 and the corresponding side surface 3b of the cap 3, the welding between the two becomes stronger.

きる。 According to the present invention, in an ultrasonic welding case in which a thermoplastic resin cap is attached to a thermoplastic resin case body and the two are ultrasonically welded at the abutting portion,
An ultrasonic welding case is provided, which is characterized in that the case body side of the abutting part of the two has a rounded surface, and the cap side has an inclined surface. Since the resin does not protrude, ultrasonic welding can be performed with excellent aesthetics. Also,
Can be welded over a wide area, improving welding strength and sealing performance.
