Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a charger holder for a mobile wireless phone.

[0002]

[Prior Art]

 Conventionally, as this type of charger holder, those shown in FIGS. 6 and 7 are known. That is, the battery charger holder 1 has the respective insertion openings 10 and 15 for charging both the mobile wireless telephone 2 equipped with the dedicated battery pack and the dedicated battery pack unit 3 simultaneously or only one of them. ing. The lock spring 19 which is made of plastic integrally with the charger holder 1 and has an elastic force has a projecting tip, which is fitted into the recess 35 provided in the battery pack unit 3 and is taken along the line AA in FIG. In FIG. 7, which is a cross-sectional view, the battery pack unit 3 is held by being pressed from both sides as indicated by two arrows D and D'on the left and right. Therefore, the single battery pack 3 is prevented from being easily detached from the charger holder 1 even if there is vibration. The lock spring 19 and the recess 35 are connected to each other to maintain the electrical contact between the electrode plate 38 and the movable electrode 40, which will be described later.

A movable electrode 40, which is biased by a spring elastic force, is in electrical contact with both electrode plates 38 of the dedicated battery pack unit 3. Further, a pair of the movable electrodes 40 is similarly provided not only for charging the dedicated battery pack unit 3 but also for charging the dedicated battery pack mounted on the mobile radio telephone 2.

[0004]

[Problems to be solved by the device]

 In the above-described conventional technique, the dedicated battery charger holder 1 has the independent openings 10 and 15 for the mobile wireless telephone 2 and the battery pack unit 3, respectively, so that the outer dimensions of the holder 1 are large. Since the movable electrode 40 is provided for both the mobile radio telephone 2 and the battery pack 3 alone, not only the number of parts is increased, but also the electric circuit is complicated and there is a problem in maintaining reliability. In addition, since the holder 1 has a complicated structure, the resin molding die structure is complicated, which causes various problems such as an increase in cost.

[0005]

[Means for Solving the Problems]

 The present invention aims to solve the above-mentioned problems of the prior art, and in order to achieve the purpose, a dedicated battery pack is provided in a holder for charging a dedicated battery pack provided in a mobile wireless telephone. It is characterized in that it can be charged when it is attached to a mobile wireless phone or when it is used as a dedicated battery pack by inserting it from a single insertion opening.

[0006]

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5, members that are the same as or equivalent to the members shown in FIGS. 6 and 7 showing the prior art are designated by the same reference numerals, and detailed description thereof will be omitted.

FIG. 1 shows an embodiment in which the dedicated battery pack 3 A is attached to the mobile radio telephone 2. The charger holder 1A has a shape to accommodate the lower portion of the mobile phone radio 2, and is made of, for example, a plastic material. An opening 10A having an area equal to that of the bottom of the wireless telephone 2 is provided in the upper portion of the holder 1A to receive the insertion of the wireless telephone 2. The electrical contact between the pair of electrode plates 38 provided on the dedicated battery pack 3A and the movable electrode 40 provided on the charger holder 1A is the same as that described with reference to FIGS. The description is omitted.

A lock spring 19A having a structure similar to that of the lock spring 19 described in FIG. 6 is provided on both side surfaces of the holder 1A, and a tip end portion 19B thereof has a projection shape and is provided on the dedicated battery pack 3A. The battery pack 3A is fitted in the recessed portion 35 so as to elastically hold the battery pack 3A as shown in FIG. 2, and also has the function of maintaining the electrical contact between the electrode plate 38 and the movable electrode 40 described above. . This electrical contact can be effectively maintained against vibration and shock. Reference numeral 70 is a lead wire connected to the movable electrode 40.

As shown in FIGS. 2 and 4, the charger holder 1A is provided with a reverse insertion preventing rail 60 on at least one side surface thereof, and a rail groove 36 provided in the dedicated battery pack 3A. Configured to mate. The fitting of the rail 60 and the rail groove 36 prevents the portable radio telephone 2 from being inserted upside down, that is, the electrode plate 38 being connected to the movable electrode 40 in the opposite polarity. obtain.

Further, as shown in FIGS. 1, 3, 4, and 5, the charger holder 1A is provided with a pair of elastic pressing springs 50 on both sides thereof integrally with the holder 1A. Since the pressing springs 50 are provided symmetrically, when the wireless telephone 2 is inserted, as shown in FIG. 3, the tip of the pressing spring 50 is pushed leftward and rightward as shown by an arrow B to be spread. The wireless telephone 2 is pressed and held almost vertically. Since the tip of the pressing spring 50 is curved inward, the contact side surface of the wireless telephone 2 can be prevented from being damaged when the wireless telephone 2 is inserted into the holder 1A and pressed.

As shown in FIGS. 4 and 5, when the dedicated battery pack 3 A is separated from the wireless telephone 2 and charged by itself, the pressing spring 50 does not have the wireless telephone 2 to be pressed. The above-mentioned pressing action is not exerted, and as shown in FIGS. 5A and 5B, the dedicated battery pack 3A comes into contact with both ends of the surface H of the dedicated battery pack 3A, and the dedicated battery pack 3A within the opening 10A is As shown by the arrow C in (b), it works to prevent the vehicle from falling forward.

[0012]

[Effect of the device]

 As described above, according to the present invention, the holder for the charger is provided with only a single insertion opening, so that it can be used even in the case of a portable wireless telephone equipped with a dedicated battery pack or a dedicated battery pack alone. However, since the prescribed charging operation can be performed, not only the shape of the holder for the charger becomes smaller, but also the number of movable contacts can be reduced compared to the conventional example, which allows the number of partial points to be reduced and the assembly time to be reduced. It is possible to achieve remarkable effects in various practical applications.
