Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a cordless telephone that establishes an electrical connection between the telephone main body and the connecting device by placing the telephone main body on the connecting device.

[Conventional technology]

A cordless telephone consists of a telephone main body and a connecting device. When not in use, the telephone main body is placed on the connecting device and electrically connected, and a charging current is supplied from the connecting device to the telephone main body. When the telephone is used, the telephone main body is separated from the connecting device, and wireless transmission and reception is performed between them. FIG. 6 shows a perspective view of a conventional cordless telephone. In the figure, the connecting device 1 and the telephone main body 4 are in a separated state. The connecting device 1 is provided with a plurality of contact terminals 3, and the telephone body 4 is also provided with contact terminals 5 at corresponding positions.
The telephone main body 4 is placed on the telephone mounting surface 2 of the connecting device 1. The telephone main body 4 is fixed by its own weight, and the contact terminal 3 on the connecting device 1 side and the contact terminal 5 on the telephone main body 4 side come into contact, and the connecting device 1 and the telephone main body 4 are electrically connected.

[Problem that the idea aims to solve]

In the above-mentioned conventional cordless telephone, the contact terminal 3 of the connecting device 2 remains exposed when the telephone main body 4 is in use, and therefore dirt and dust are likely to adhere thereto. Furthermore, since the telephone main body 4 is fixed only by its own weight, there are disadvantages in that poor connections are likely to occur and the sense of stability is poor. The present invention was developed to solve the above-mentioned problems, and provides a cordless telephone that can stably fix the telephone body to the connecting device and also ensure the electrical connection between the connecting device and the telephone body. The purpose is to

[Means to solve the problem]

A connection mechanism for a cordless telephone according to the present invention, which has been developed to solve the above problems, will be explained using FIGS. 1 to 3, which correspond to embodiments. As shown in these figures, the cordless telephone of the present invention connects the contact terminal 5 on the telephone body 4 side to the connector 1 by placing the telephone body 4 on the connector 1.
In a cordless telephone that is connected to the contact terminal 3 on the side, the connecting device 1 has the connecting device 1 covering the contact terminal 3.
A slide plate 7 and a sliding guide claw 9 that can be slid along
The telephone main body 4 is provided with a pressing portion 12 that contacts and presses the slide plate 7, and an engaging claw 14 that can engage with the sliding guide claw 9.

[Effect]

In the above cordless telephone, when the telephone body 4 is removed from the connecting device 1, the contact terminal 3 of the connecting device 1 is covered with the slide plate 7. Connector 1
When the telephone main body 4 is placed on the terminal and the telephone main body 4 is slid along the connecting device 1, the engaging claw 14 engages with the sliding guide claw 9, thereby fixing the telephone main body 4 to the connecting device 1. do. During sliding, the slide plate 7 covering the contact terminals 3 of the connecting device 1 is pushed by the pressing member 12 of the telephone main body 4 and slides. Therefore, the contact terminal 3 is exposed, and the contact terminal 5 of the telephone main body 4 slides and comes into contact therewith. Therefore, the telephone main body 4 and the connecting device 1 are electrically connected.

【Example】

Examples of the present invention will be described in detail below. 1 to 5 show the main parts of an embodiment of a cordless telephone to which the present invention is applied. FIG. 1 shows a front view of the connecting device 1 facing the telephone main body. In the figure, reference numeral 9 denotes a pair of sliding guide claws provided at the upper end and center of the surface 2 of the connecting device 1 on which the telephone main body is placed. 10
is a backing plate erected between the sliding guide claws 9 at a lower height than the sliding guide claws 9. Reference numeral 7 denotes a slide plate that slides on the mounting surface 2, and has a protruding piece 8 that protrudes upward at the center tip. The slide plate 7 is the fourth
As shown in the cross-sectional view of the figure, it is urged upward by a spring 11. This slide plate 7 covers the contact terminals 3, and is configured so that the contact terminals 3 are exposed when sliding downward. FIG. 2 shows a front view of the telephone body 4 facing the connector. In the figure, reference numeral 14 denotes a pair of engaging claws provided at the upper end and at the center.
The engaging claws 14 are provided to protrude inwardly from both ends of the recess 15 of the telephone body 4, and are designed to engage with the sliding guide claws 9 of the connector 1, as shown in FIG. 3 (lower cross-sectional view). It is composed of 5 is the phone body 4
A plurality of contact terminals 12 are recessed portions for pressing the slide plate 7 of the connecting device 1. In the recess 12,
The protruding piece 8 of the slide plate 7 engages. The operation of the connection mechanism of the cordless telephone configured as described above will be explained. When the telephone body 4 is removed from the connector 1, the slide plate 7 covers the contact terminal 3, as shown in FIG. When the telephone body 4 is placed on the connector 1 from this state, the protruding piece 8 of the slide plate 7 is inserted into the recess 12 of the telephone body 4, as shown in FIG. At the same time, the sliding guide pawl 9 of the connecting device 1 also enters the recess 15 of the telephone body 4, and the telephone body 4 comes into contact with the mounting surface 2 of the connecting device 1. Here, connector 1
The telephone main body 4 is slid along the mounting surface 2 in the direction shown by the arrow. Then, the upper surface of the pressing recess 12 hits the protruding piece 8 of the slide plate 7, and the spring 1
The slide plate 7 is moved downward against the biasing force of the slide plate 7. Next, the telephone main body 4 hits the backing plate 10, and the engaging claw 14 engages with the sliding guide claw 9 of the connector 1. When the telephone main body 4 is completely slid downward, the slide plate 7 moves below the contact terminal 3 and the contact terminal 3 is exposed, as shown in FIG. Then, the contact terminal 5 of the telephone main body 4 comes into contact with the contact terminal 3. The engaging pawl 14 of the telephone main body 4 completely engages with the sliding guide pawl 9 of the connector 1. When removing the telephone main body 4 from the connector 1, by sliding the telephone main body 4 upward, the contact terminal 5 is separated from the contact terminal 3, and the spring 11 causes the sliding plate 7 to slide upward, and the contact terminal 3 slides. Covered by plate 7.

[Effect of the idea]

As explained above, in the cordless telephone to which the present invention is applied, the contact terminal of the connecting device is covered with a sliding plate when the main body of the phone is removed from the connecting device, so that dirt and dust do not get on the connecting contact terminal. Adhesion can be prevented.
Furthermore, by engaging the claws of the telephone body with the claws provided on the connector, the telephone body can be stably fixed to the connector. Therefore, the connecting device can be used while leaning against the cordless telephone, making it easier to use the cordless telephone. Furthermore, when fixing a cordless phone, the contact terminals are exposed by sliding the slide plate that covers the contact terminals of the connection device, and the contact terminals are brought into contact with the contact terminals on the phone body, allowing electrical connections to be made. reliability can be improved.
