DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for electrically connecting electrical equipment and a connection structure between the electrical equipment main body and the electrical equipment split by the connector.

[0002]

2. Description of the Related Art Heretofore, in a separately movable electronic device such as a wireless telephone main unit of a cordless wireless telephone handset and a transmission / reception unit, electrical connection is made via a flexible substrate. Was.

[0003]

However, in the connection structure using a flexible substrate, it is difficult to assemble the wireless telephone main body and the transmission / reception section as finished products.
The integration is performed manually, which has been a bottleneck in the automation of assembly. In addition, since the flexible substrate is easily damaged, a protective structure is required, and the structure must be invisible from the outside. Therefore, there has been a problem that the entire circuit board becomes large and the design is extremely disadvantageous.

Accordingly, an object of the present invention is to provide a small and compact connector capable of electrically connecting mutually movable electric devices. It is another object of the present invention to provide a connection structure between the electric device main body and the electric device split body by a connector capable of compactly connecting the electric device main body and the electric device split body rotatably connected to each other.

[0005]

SUMMARY OF THE INVENTION For this purpose, the present invention provides a hollow holder, a hollow first pin slidably inserted in one end of the hollow holder in an axial direction thereof, and a hollow holder. A second pin slidably inserted in the axial direction from the end side into the inside of the first pin;
The connector is constituted by a spring that repels the pin in the axial direction.

[0006]

According to the above construction, by inserting the second pin into the inside of the first pin, the overall length is reduced, and the first pin is inserted.
Both the pin and the second pin are slidable connectors with double terminals, and a waterproof structure can be provided by a waterproof ring.

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings. 1, 2, and 3 are cross-sectional views of a connector according to an embodiment of the present invention, FIG. 4 is an exploded perspective view of the wireless telephone handset, and FIG. FIG. In FIG. 1, reference numeral 1 denotes a hollow holder made of synthetic resin or the like, and a hollow first pin 2 is provided at one end thereof.
Are slidably inserted in the axial direction. A second pin 3 is inserted from the other end side, and the tip of the second pin 3 is inserted inside the first pin 2 so as to be slidable in the axial direction. A spring 4 is housed inside the first pin 2, and a second force is generated by the spring force.
The pin 3 is repelled upward.

The upper end of the first pin 2 has an enlarged portion 5, and a projection 6 is provided on the inner surface of the lower end of the hollow holder 1. 1 prevents the pin 2 from coming off. A large diameter portion 7 is formed near the lower end of the second pin 3, and the upper end of the first pin 2 is bent inward to form a bent portion 8. This large diameter part 7
The bent portion 8 serves as a stopper for the second pin 3.
A cap 9 is attached to the upper end of the hollow holder 1, and a waterproof ring 10 is provided inside the cap 9. The inner peripheral surface of the waterproof ring 10 has a second pin 3
, And the outer peripheral surface of the waterproof ring 10 abuts the inner peripheral surface of the hollow holder 1, and seals to prevent external water from entering the inside of the hollow holder 1.

FIG. 2 shows a case where an external force P acts on the tip of the second pin 3. In this case, the second pin 3 descends while compressing the spring 4. FIG. 3 shows the first
3 shows a case where an external force F also acts on the pin 2 of FIG. In this case, the first pin 2 also rises while compressing the spring 4. Further, in this case, the reaction force against the external forces P and F is uniformly distributed as (P + F) / 2 to the first pin 2 and the second pin 3 by the spring 4, so that the stress balance is good. Also, in FIG.
C, the distance between the upper surface of the first pin 2 and the waterproof ring 10 is D, the stroke of the first pin 2 is H, and the stroke of the second pin 3 is G in FIG. In this case, the first pin 2 and the waterproof ring 10 are attached to the electric device so that H <D and G + H <C.
Does not collide, nor does the first pin 2 and the second pin 3 collide, so that these components can be prevented from being damaged. In addition, since the second pin 3 is configured to slide inside the first pin 2, a connector having a small and compact double-terminal structure can be obtained.

Next, an example of use of the connector will be described with reference to FIGS. In FIG. 4, reference numeral 11 denotes a cordless wireless telephone main body, and a connecting portion 12 is provided at one end thereof in a groove shape. In this connecting part 12,
The connector is mounted with the second pin 3 protruding upward. In FIG. 5, a wiring board 13 is provided inside the wireless telephone main body 11, and the first pins 2 are in contact with the terminals 14 of the wiring board 13. An E-ring 15 for waterproofing is provided on the outer periphery of the hollow holder 1. 16 is a waterproof packing, and 17 is a cover part.

Reference numeral 20 denotes a drum-shaped contact portion, which has a shaft 21 made of a spring rod, and two ring-shaped terminals 22 are formed on the peripheral surface thereof. Reference numeral 23 denotes a transmission / reception unit. The contact section 20 is attached to an end of the transmission / reception section 23. In FIG. 5, the upper end of the second pin 3 elastically contacts the terminal 22 with the contact part 20 attached, and in this state, the contact part 20 is integrated with the transmitter / receiver unit 23 in the wireless telephone main body 11.
, And a contact structure with reliable contact can be realized.
In addition, since the play and shaping error during rotation of the transmission / reception unit 23 can be absorbed by the spring force of the spring 4, the transmission / reception unit 23 can be smoothly rotated.

[0012]

As described above, according to the present invention, it is possible to realize a connector having both terminals which is small, compact and excellent in waterproofness. Also, according to this connector, it is possible to easily connect and assemble the electric device main body and the electric device splitter, thereby reducing costs, and also ensuring the electrical connection, and further improving reliability. A high waterproof structure can also be used.
