Abstract

PURPOSE:To facilitate the attaching/detaching operations of a battery pack and to improve the water proof property of the battery pack by providing a receptacle containing a projection having a rail to be engaged with a guide rail and a rubber ring set on the front edge face of the projection to the battery pack side mechanism. CONSTITUTION:The projecting part 28 of an inside end part of a guided projection 22 of a battery pack 12 is coincident with the distance (l) between a guide rail 15 of a radio equipment main body 10 and the front edge of a 1st bottom surface 14. Then a pack side connection mechanism 13 is put into the front edge side of a main body side connection mechanism 11 so that the inside end part 15a of the rail 15 of the mechanism 11 is fitted into a space S. Thus a pair of terminals 16 are set into the holes 29 of a receptacle 23 and connected electrically to an inside terminal. Then the outer circumference of the receptacle 23 is covered with the inner circumference of a sleeve 17 and the entering of rainwater can be prevented by a rubber ring 24. In such a constitution, the pack 12 can be easily attached to and detached from the main body 10 and the waterproof property is improved at a terminal part.

[0002]

2. Description of the Related Art In a portable radio device of a type in which a battery pack containing a battery for a power source is attached / detached, it is necessary to secure the attaching / detaching operability of the battery pack and the waterproofness of the electrode portion. Proposals have been made.

5 (a) and 5 (b) are a side view and a front view showing an example of a structure for attaching / detaching a battery pack in a conventional portable wireless device, and FIG. 5 (b) is a bottom view of the portable wireless device main body 1. Such an inverted T-shaped guide protrusion 3 is provided, and positive and negative terminals 4 are provided on the bottom surface of the guide protrusion 3. On the upper surface of the battery pack 2 which is attached to and detached from the bottom surface of the portable wireless device body 1, there is provided a reverse L-shaped guided rail 5 that matches the outer shape of the guide protrusion 3 on the bottom surface of the wireless device body 1 and its bottom surface. An electrode 6 that can be connected to the terminal 4 on the bottom surface of the wireless device main body is arranged in the. A lock hole 7 is formed at the end of the upper surface of the battery pack 2, and a lock piece 8 that can be fitted into the lock hole 7 is provided at the end of the bottom surface of the wireless device body 1 by a spring (not shown) in the protruding direction. Support in a biased state. The wireless device main body 1 and the battery pack 2 are connected by inserting the guided rail 5 into the guide protrusion 3 as shown in FIG.
The end portion 5a of the guided rail 5 is the stopper portion 1 on the main body 1 side.
The connection is completed by fitting the lock piece 8 into the lock hole 7 when it comes into contact with a.

This conventional attaching / detaching structure has an advantage in that the battery pack can be easily attached / detached and is unlikely to fall off even if the lock is released. However, since the waterproof structure of the terminal portion connected to the electrode on the battery pack side is not sufficient, problems such as electric contact due to infiltration of rainwater are likely to occur. Also, the guide protrusion 3
Since it is difficult to integrally manufacture the wireless device main body 1 and the wireless device main body 1, the guide protrusion 3 is a separate component, resulting in an increase in assembly man-hours due to an increase in the number of components.
