Abstract

PURPOSE:To obtain stable electric connection between a handset and a cradle by devising the handset and the cradle such that 1st and 2nd connector themselves connecting electrically the handset and the cradle are fitted together to hold the handset onto the cradle. CONSTITUTION:When the handset 10 is mounted onto the cradle 11, a latching part is fitted to a recessed part at a reception section 15 and the tip part 21 of a connector 18 is fitted to the recessed part 32 of a connector 14, then the handset 10 is fitted tightly by the cradle 11. The tip part 21 of the connector 18 is shaped as a taper toward its tip and the tip part 21 is fitted accurately to the recessed part 32 of the connector 14. Thus, both the connectors 14, 18 are connected electrically surely. In this case, since both the connectors 14, 18 are positioned relatively by themselves, a problem such that the relative position of both the connectors is dislocated forcibly due to the dislocation of the latch is not generated.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a wireless telephone such as a car telephone.

(Conventional technology) FIG. 7 shows a conventional car phone.

In the figure, 1 is a handset, and 2 is a cradle on which the handset 1 is placed. A connector 3 is provided on the bottom surface of the handset 1, and a connector 4 is provided on the top surface of the cradle 2. When the handset 1 is placed in a predetermined position on the cradle 2, the connectors 3 and 4 are electrically connected, and the handset 1 is charged. Further, in the case of a car phone, it is necessary to firmly hold the handset 1 in the cradle 2 so that the handset 1 does not fall off during photographing.

Therefore, there is a recess (
(not shown) is provided with a latch part 7 that fits into the recessed part in the receiving part 6 of the cradle 1 that receives the transmitting/receiving part 5, and when the handset 1 is placed on the cradle 2, this latch part 7 fits into the recessed part. By fitting the handset 1 into the cradle 2, the handset 1 is held in the cradle 2. Note that the lock by the latch portion 7 is released by pressing the push button 8.

However, in the above structure, the relative positions of the connector 3 and the connector 4 are regulated by the fitting between the recess and the latch part 7, so that the connector 3 and the connector 4 may Misalignment occurred between the two, making it difficult to establish stable electrical contact between the two.

(Problems to be Solved by the Invention) As described above, in conventional wireless telephones, poor contact occurs between the connectors that electrically connect the handset and the cradle due to looseness of the latch that holds the handset in the cradle. There was a case.

The present invention has been made in view of these conventional drawbacks, and when the handset is held in the cradle,
It is an object of the present invention to provide a radio telephone in which both connectors can be reliably connected and a stable electrical connection can be obtained between the two.

[Structure of the Invention] (Means for Solving the Problems) In the radio telephone of the present invention, the handset is provided with the first connector, and the cradle is provided with the first connector of the handset placed at a predetermined position on the cradle. A second connector is provided which is electrically connected to the first connector and fitted into the first connector to hold the handset in the cradle.

(Function) According to the above configuration, the first and second connectors for electrically connecting the handset and the cradle are fitted together to establish a mechanical connection between the handset and the cradle. Therefore, the relative positions of both connectors are not affected by other parts such as conventional latch portions and recesses, and the electrical connection by both connectors is ensured.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 to 6.

FIG. 2 is a perspective view of the car telephone, in which 10 is a handset and 11 is a cradle on which the handset 10 is placed. Transmitter 13 of this handset 10
A female connector 14 is provided on the side surface, and a recess (not shown) similar to the conventional example is provided on the side surface of the receiver section 15. Further, a male connector 18 that is electrically connected to the connector 14 is provided in the receiving part 16 corresponding to the talking part 13 of the cradle 11, and the receiving part 19 corresponding to the talking part 15 has the recessed part. A conventional latch portion (not shown) is provided which mates with the conventional latch portion (not shown).

As shown in FIG. 3, the housing 20 of the male connector 18 has a tapered tip 21, and a plurality of grooves 24 for inserting the contacts 23 from the tip 21 to the base 22. has been done. As shown in FIG. 4, the contactor 23 is attached to the housing 20 by being inserted into the housing 20 from the tip end 21 side. Furthermore, as shown in FIG.
6 is prominently displayed.

As shown in FIG. 5, the housing 30 of the female connector 14 has a front surface 31 formed with a recess 32 that fits into the tip 21.
A plurality of grooves 36 for inserting the contacts 35 are formed from the part to the back surface part 34. Also, this groove 36
A pin 37 is provided so as to penetrate through it. and,
The negative end of the contact 35 is attached to this pin 37 as shown in FIG.
The other end is inserted into the hole 38 and attached to the housing 30. This connector 14
As shown in the figure, when the handset 10 is placed on the cradle 11, the tip 21 of the connector 18 is inserted into the recess 32.
are provided on the handset 10 at a position where they can be fitted (therefore, a position where the contacts 18 and 35 are connected).

In the telephone configured as above, the handset 10
When placed on the cradle 11, the latch part fits into the recess on the receiving part 15 side, and the tip 21 of the connector 18 fits into the recess 32 of the connector 14 on the sending part 13 side (the first ), the handset 10 is held firmly in the cradle 11. Further, the tip end 21 of the connector 18 has a tapered shape, and the tip end 21 fits accurately into the recess 32 of the connector 14. Therefore, both connectors 14 and 18 are electrically connected reliably. In this case, since the relative positions of the two connectors 14 and 18 are determined by themselves, the relative positions of the two connectors 3 and 4 are forcibly shifted due to the displacement of the latch portion 7, etc., as in the conventional case. This problem does not arise. The connector 18 and the latch are unlocked by pressing the push button 8, as in the prior art. In this example, only two sets of latch parts and one set of recesses in the conventional example are replaced with connectors 14 and 18, but instead of using the conventional latch parts and recesses, for example, two sets of recesses are replaced. Handset 10 may be held in cradle 11 using connectors 14,18.

[Effects of the Invention] As explained above, in the wireless telephone of the present invention, the first and second terminals electrically connect the handset and the cradle.
Since the connectors themselves fit together to hold the handset in the cradle, the relative position of both connectors will not be affected by misalignment of other parts, etc.
A stable electrical connection between the handset and the cradle can be obtained.
