【Example】

Embodiments of the present invention will be described below with reference to the drawings. Figure 1 shows an example of the present invention. show. The main body 1 of the wireless telephone is, for example, a rectangular parallelepiped case, and a part of it has A notch 6 is formed to accommodate the battery unit 10. One of the notches 6 A guide groove 7 formed in the pair of outer walls of the battery unit 10 is formed in the pair of inner walls. Projections 8A and 8B are formed corresponding to A and 7B. Furthermore, the flat surface facing the notch 6 is Protruding from the surface are receiving terminals 3 and 4 that are connected to the internal wireless circuit and receive power. It is provided. A horizontally long bar piece 7 is provided below the receiving terminals 3 and 4. . The receiving terminals 3 and 4 protrude further toward the notch 6 than the bar piece 7. On the other hand, the battery One side of the unit 10, when the battery unit 10 is attached to the notch 6. A supply terminal connected to the internal battery is located opposite the supply terminals 3 and 4. 11 and 12 are buried. A rectangular window 13 is formed in the supply terminals 11 and 12. It is. A movable mask plate 14 is embedded in the window 13, and is biased by a spring, for example. 2 and the battery unit 10 is removed, as shown in Figure 2. The supply terminals 11 and 12 are covered as shown in FIG. A rod is attached to the upper end of the movable mask plate 14. A shaped protrusion 15 is provided, and by holding this protrusion 15 and applying downward force, Supply terminals 11 and 12 can be exposed.

0010 It has the main body 1 and the battery unit 10 configured as above, and the window 13 is connected to the receiving terminal. Insert the battery unit 10 from below the notch 6 so as to face 3 and 4. Ru. As a result, the protrusions 8A, 8B and the guide grooves 7A, 7B fit together, and the battery - Unit 10 can be slid upwards. Place battery unit 10 upwards. When it is slid, the protruding piece 15 comes into contact with the rod piece 7, and the movable mask plate 14 is pushed down and the supply end The terminals 11 and 12 are exposed, and the supply terminals 11 and 12 and the reception terminals 3 and 4 are brought into contact and wireless connection is established. Power is supplied to the circuit.

[0011] Note that the direction in which the battery unit is inserted in this example is just an example, and may be inserted horizontally, etc. It may also be inserted from there. In addition, a means for biasing the movable mask plate 14 and a movable mask plate 14 are also provided. The means of movement when opening the board can also be realized using magnets, etc. that do not affect the circuit. Ru.

0012 Another embodiment of the present invention will be described with reference to FIGS. 3 and 4. The main body in this example The shape is almost the same as that shown in FIG. 1, but the notch 6 is provided with protrusions 8A and 8B. Although not shown, there are protrusions on some of the protrusions 8A and 8B, for example. Correspondingly, recesses are formed in part of the guide grooves 7A and 7B of the battery unit 10A. , the battery unit 10A can be fitted by pushing it in the direction of arrow A in Figure 3. Ru. In addition, supply terminals 11 and 12 of the battery unit 10A are buried in an exposed state. , does not have a window or other structure. On the other hand, the receiving terminals 3 and 4 are provided protruding from the notch 6. I'm being kicked. The rod piece 11 as shown in FIG. 1 is not provided. However, below the notch 6 A protruding piece 5 is formed in the part, and a battery unit 10A is attached to the notch part 6. A hole 16 is formed at the position of the battery unit 10A corresponding to the protruding piece 5. A normally open switch 17 that is pressed and closed by the protruding piece 5 is provided inside. always The open switch 17 is provided in the power supply path where the battery 20 and the supply terminals 11 and 12 are connected. It is being

[0013] The battery unit 10A configured in this way is powered by the normally open switch 17. Since the supply path is cut off, no voltage is applied to supply terminals 11 and 12, causing a short circuit. There is no risk of contact. On the other hand, as shown in Figure 3, mark the battery unit 10A with the arrow When pushed in the direction of A and attached to the notch 6 of the main body 1, the supply end will open as shown in FIG. The terminals 11 and 12 contact the receiving terminals 3 and 4, and the protrusion 5 passes through the hole 16 to the normally open switch. The switch 17 is closed by pressing the switch 17. This eliminates the voltage from battery 20. applied to line circuit 2. Note that in this example, the normally open switch was closed by pushing it with a protrusion, but the normally open switch The opening may also be closed by other means, such as by a magnet.

[0014] As explained above, according to the present invention, the battery unit is attached to the main body. When not in use, the supply terminal is covered by the movable mask part or the normally open switch is closed. The opening may also be closed by other means, such as by a magnet.

[0015]

[Effect of the idea]
