Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement in a charging terminal for a cordless telephone device.

[Prior Art] A cordless telephone device includes a cordless telephone in which a charging terminal is exposed on the peripheral surface of a mouthpiece, and an opening in which the terminal is provided in a part of the peripheral wall of a mouthpiece fitting recess. A stand that has a charging terminal protruding from the wall and connected to a power source via a power connector (if this stand is equipped with a telephone function, wireless function, etc.,
Generally, it is called a base phone, and a handset-type cordless phone is called a handset. ). A cordless telephone has a built-in rechargeable battery, and this built-in battery is placed in a charging state when the charging terminal and the terminal portion come into contact with each other when the telephone is placed on a stand. In conventional cordless telephone devices, the structure of the charging terminal is a leaf spring type or a plunger type. In the former case, the charging terminal board is made of an elastic plate material, and one end of the terminal board is fixed to the inner wall of the stand, and the other end of the terminal board is bent into a substantially square shape, and this bent part is inserted through the opening into the mouthpiece. It is made to protrude into the fitting recess. The advantages of this leaf spring type are that it is inexpensive, and that it has a so-called self-cleaning effect on the terminal surface because the surface of the bent part slides into contact with the surface of the charging terminal of the phone due to elastic deformation. On the other hand, there was a problem in that the terminal board was deformed when the telephone was strongly pressed onto the stand, resulting in frequent failures in contact between the controls. In addition, the plunger type has a plunger terminal built into the sealing case that is given a protruding habit by a spring, and the tip of the plunger terminal usually protrudes from the opening of the mounting base into the mouthpiece fitting recess. ing. This plunger type terminal structure has the advantage that the terminal is never deformed by external force, and the contact pressure between the terminals can be adjusted by appropriately changing the tension of the spring. On the other hand, since the plunger terminal simply moves in a straight line by protruding and retracting from the opening, there is no self-cleaning effect on the terminal surface, and there are disadvantages such as high cost.

[Problem that the invention aims to solve]

The charging terminal structure of a cordless telephone device is simple and inexpensive, the terminal part does not deform even when external force is applied, and the contact between the terminals is maintained well, and the terminal surface has a self-cleaning function. However, a charging terminal structure equipped with all such functions has not yet been provided.

[Means to solve the problem]

In view of the above, the present invention provides an engagement support piece and a spring retaining piece integrally with the opening on the inner wall of the placing stand in correspondence with the opening provided in the peripheral wall of the mouthpiece fitting recess of the placing stand, and also provides a metal plate. to form a terminal member having an engagement hole, a spring hooking part, a soldering part, and a terminal part, and the terminal member is assembled by aligning the engagement support piece and the engagement hole with the terminal part facing the opening. After the two engaging parts are engaged with each other, a spring is stretched between the two engaging parts.

[Effect]

According to the charging terminal structure according to the present invention configured as described above, the structure of the mounting stand and the terminal member is extremely simple, and the terminal part is moved from the opening by the acting force of the spring stretched between both the latching parts. When the cordless telephone is placed on the stand, the terminal member, which is rotatably assembled to the engagement support piece so as to have a protruding tendency, rotates against the acting force of the spring. As a result, the terminal portion is held in contact with the charging terminal piece of the telephone while sliding on the surface thereof, so that it also has a self-cleaning effect.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in the drawings.

The cordless telephone device shown as an example is composed of a handset-type cordless telephone 1 and a stand 10, and a pair of charging terminals 3 are provided on a part of the circumferential surface of the mouthpiece 2 of the telephone 1. (see Figure 3), and the stand 10 is a long box-shaped Atsupa case 11.
and a lower case 12.
A fitting recess 13 into which the mouthpiece 2 of the cordless telephone 1 is fitted is provided on one side of the Atsupah case 11, and a peripheral wall 14 constituting this fitting recess is provided with a fitting recess 13 corresponding to the charging terminal 3. A pair of openings 15 are provided. Corresponding to this opening 15, a hook-shaped engagement holding piece 16 and a spring hooking piece 17 are each integrally formed on the outer surface of the peripheral wall of the upper case 11 (which becomes the inner wall of the stand 10 when combined with the lower case 12). is formed. In addition, in FIG. 1, hook-shaped protrusions 18 formed on the center and both sides of the outer wall of the upper case 11 engage with the engaging portions 19 provided on the inner wall of the lower case 12 to integrate both cases. This is an engaging piece.

A terminal member 20, the details of which are shown in FIG. 4, is assembled to the engagement and holding piece 16. The terminal member 20 formed of a metal plate has an engagement hole 21 formed by punching out the center part in a U-shape, and a spring hook part formed by bending the remaining tongue piece into a crank shape. 22
and a terminal part 24 in which a soldering part 23 is formed protruding from one side edge and a protrusion protruding from the lower edge is bent into a U-shape so as to protrude on the opposite side from the spring hooking part. The upper edge portion 25 is slightly bent toward the opposite side from the terminal portion. Of course terminal part 2
The width dimension of the opening 4 is slightly smaller than the opening dimension of the opening 15, and a dowel 26 is formed on the surface, and the hole dimension of the engagement hole 21 is slightly smaller than the opening dimension of the opening 15.
It is said that the cross-sectional dimension is slightly larger than that of . Further, although not shown, a power supply connection terminal is incorporated in the mounting base 10, and a lead wire extended from this terminal is connected to the soldering portion 23. The shape and arrangement of this soldering part can be changed as appropriate.

As shown in FIGS. 2 and 3, the terminal member 2
0, the terminal part 24 is made to face the opening 15, the engagement hole 21 is engaged with the engagement holding piece 16, and then the tension spring 30 engaged with the catch part 22 and the catch part 17 is It is combined with the upper case 11 through it. This allows the upper part to engage with the holding piece 1.
The terminal member 20 rotatably supported by the spring 30 is biased clockwise in FIG. It is exposed protrudingly inside.

As shown in FIG. 3, when the cordless telephone 1 is placed on the stand 10, the weight of the telephone causes the terminal member 20 to rebound about the engaging and holding piece 16 as a fulcrum against the force of the spring 30. Rotate clockwise. Of course, in the placed state, the terminal portion 24 of the terminal member 20 contacts the charging terminal piece 3 of the telephone, but as the terminal member 20 rotates, the surface of the terminal piece slightly slides into contact with the inside of the opening 15. Since the terminal piece 3 and the terminal portion 24 are retracted, a self-cleaning action is performed between the terminal piece 3 and the terminal portion 24. Note that by appropriately adjusting the tension of the spring 30, changes in the weight specifications of the cordless telephone 1 can be easily accommodated.

[Effects of the invention] As explained in detail above, according to the invention,
Although the number of springs increases compared to the conventional leaf spring type, the terminal member made of a metal plate does not deform even if some external force is applied, making it suitable for charging cordless phones. The contact state with the terminal piece is always maintained stably, and
It also has a self-cleaning effect on the surface of the terminal, and has an extremely large practical effect.
