In addition, a spare rechargeable battery is always being charged or fully charged in the battery compartment 16 of the base unit 13, and the rechargeable battery 3 of the slave unit 1 is inserted into the battery compartment 14. When you don't have time to charge the battery, replace it with a spare rechargeable battery. Note that 17 is a battery cover on the main unit side.

Problems to be Solved by the Invention However, in the cordless telephone configured as described above, when inserting the handset into the handset housing of the base unit, the handset must be inserted in the opposite direction as shown in FIG. If the charging terminals of the base unit and slave unit do not contact each other and the unit does not charge, or if the battery cover is not properly attached (not shown), the slave unit may not be placed in the slave unit compartment. There was a problem that even if the battery was inserted, it would not charge and people would mistake it for a malfunction.

Means for Solving the Problems In order to solve the above problems, the electrical equipment of the present invention is provided with protrusions on one side of the battery cover and on the part of the equipment body that faces the battery cover when the equipment body is installed in the handle. The other side is provided with a groove that engages with the protrusion, and the groove and the protrusion are configured to engage only when the battery cover is attached to a predetermined position with respect to the battery storage portion.

When inserting the operating device main body into the storage portion of the charger, the battery cover must be properly attached and the device main body must be inserted in the correct direction with respect to the charger.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings, taking a foldable cordless telephone as an example.

FIG. 1 is a diagram showing a state in which a handset of a cordless telephone according to an embodiment of the present invention is folded.

Figure 2 is a side view of the handset shown in Figure 1, Figure 3 is a back view of the handset shown in Figure 1, Figure 4 is a perspective view of the parent unit, and Figure 5 shows the handset inserted into the parent unit. A perspective view showing the state, and FIG. 6 is a cross-sectional view of the state shown in FIG. In the figures, the same parts as in the conventional example are given the same numbers and their explanations are omitted.

Reference numeral 18 denotes a battery cover, and a groove 19 that widens toward the end is formed on its surface. Reference numeral 20 denotes a protrusion formed on the side surface of the child device housing section 14 of the parent device 13 so as to widen toward the end, and is configured to engage with the groove 19 of the battery cover 18 . Reference numeral 21 denotes a battery cover of a battery storage section provided on the base unit side for charging a spare battery, and is the same as the battery cover 18 described above.

Furthermore, the battery covers 18 and 21 have a structure, for example, a bayonet structure, in which they are fixed by being rotated relative to the battery storage portions of the child device and the parent device.

The operation of the cordless telephone of this embodiment configured as described above will be explained below.

First, when installing the rechargeable battery 3 in the handset in order to replace the rechargeable battery with a spare rechargeable battery, etc., insert the rechargeable battery 3 into the battery compartment 2 of the handset, Cover the lid 18 and rotate the battery lid 18.

Then, the battery storage section 2 and the battery i18 are locked by the bayonet structure described above. In this locked state, the groove 19 of the battery cover 18 is formed in advance so that the wider side of the groove is on the insertion side into the parent unit. When the handset 1 is inserted into the handset accommodating portion 14 of the base unit 13 in this locked state, the groove 19 advances while guiding the protrusion 20 and the two are engaged, as shown in FIG. Here, if the battery cover 18 is not attached correctly, the groove 19 of the battery cover 18 will not fit well with the protrusion 20 of the slave unit housing part 14, and the slave unit will not be able to be inserted. Furthermore, when attempting to insert the handset into the handset housing with the handset reversed left and right, the protrusion 20 comes into contact with the bottom or side surface of the handset, making it impossible to insert the handset. Therefore, the user can recognize that the battery cover 18 is not attached correctly or that the handset is inserted in the wrong direction. In addition, even if the battery M18 is installed at a position slightly shifted from the normal lock position, the groove 19 of the battery cover 18 is configured to have a wide groove width on the side where it is inserted into the base unit, so the tip of the projection 20 (this As mentioned above, the width of the protrusion at the tip is narrower than that at the rear (
Since the battery M18 is easily guided into the groove 19 and advances, any slight mounting misalignment of the battery M18 can be corrected to the correct mounting position as the handset advances, which is very convenient. . Furthermore, if the coins are configured to be able to fit into the groove 19 of the battery cover 18, the battery cover can be easily attached.

In this embodiment, a groove 19 is provided in the battery cover 18 of the handset 1,
Although the protrusion 20 is provided in the handset housing 14 of the base unit 13, a protrusion may be provided on the battery cover and a groove may be provided in the handset housing 14 to engage with the projection. In this case, the protrusion on the battery cover should be narrower at the end so that the width on the side where it is inserted into the base unit is narrower, and the groove in the child unit housing should also be narrower at the end so that the width on the entrance side is wider. The above-mentioned effects can be achieved if the film is formed in a large size.

Effects of the Invention As described above, the present invention has a device body that uses a rechargeable battery as a power source and is constructed so that the rechargeable battery can be replaced, and a groove or protrusion is provided on the battery cover of the rechargeable battery. A charger equipped with a storage part into which the main body of the device can be attached is provided with a protrusion or groove that engages with the groove or protrusion, and the battery cover is attached at a predetermined position with respect to the battery storage part. Since the groove and the protrusion are configured so that they only engage with each other, when inserting the main body of the device into the storage section provided on the charger, the battery cover must be placed almost completely in its normal position. It also prevents the device from being inserted in the wrong direction, and prevents the problem of the device's rechargeable battery not being charged even though the device is inserted into the charger compartment. The effects are significant.
