The three connector parts include: a charging connector part 6 for charging the built-in battery; a data signal connector part 8 for connecting the portable phone 2 with a personal computer or the like via a communication cable; and a headset connection The receiver portion 10, to which the terminals of a headset can be connected. In the connector 4 of the present embodiment, the three connector parts 6 , 8 , and 10 are integrally provided in a resin molded body 14 , and this resin molded body 14 is mounted in the cellular phone 2 .

As shown in FIG. 4, the connector 4 of this embodiment is attached to the end of the mobile phone main body, and the key 3 of the mobile phone 2 is provided on this mobile phone main body. The contacts of the connector 4 are exposed, and the connector 4 is connected to a circuit board mounted in the main body of the cellular phone.

Next, the structure of the connector 4 of the present embodiment will be described. As shown in Figure 1, the terminals 16, 18 and 20 have respective contact portions 12, the contact portions 12 are used to respectively connect with the contacts on the mounting circuit board (not shown), and the terminals 16, 18 and 20 are connected with It is installed on the upper surface of the connector 4 in a protruding manner. The contact terminal 16 is connected with the charging connector part 6 , while the contact terminal 18 is connected with the data signal connector part 8 , and the contact terminal 20 is connected with the headset connector part 10 . Each of the contact terminals 16, 18 and 20 is formed by punching out a sheet of an appropriate shape from a thin metal plate, bending it, and then subjecting it to a plating process to provide the contact terminals 16, 18 of such a shape. Or 20 , the contact terminal elastically protrudes from the upper surface of the connector 4 . The contact portion 12 at the end of each contact terminal is bent into a generally semicircular shape.

As shown in FIG. 1B, in one end face of the resin molded body 14 perpendicular to its upper surface, insertion openings 9, 11, and 13 are formed, and the contact terminals 16, 18, and 20 protrude from the upper surface, and external plugs can be inserted. and sockets are respectively inserted into these insertion openings to be electrically connected with the connector portions 6, 8 and 10, respectively. In the resin molded body 14 , the contact terminals 16 , 18 , and 20 are connected to their respective joint contacts, and these contacts are exposed in the insertion ports 9 , 11 , and 13 . The end face of the connector 4 shown in FIG. 1B has such a shape and size that the connector portions 6, 8, and 10 are disposed on the end face, and that the end face is disposed within the end face of the portable telephone 2. In the connector 4 of the present embodiment, the data signal connector portion 8 is arranged between the charging connector portion 6 and the headset connector portion 10 .

The data signal connector portion 8 of the connector 4 of the present embodiment includes data signal terminals 24 provided in the insertion opening 11 and connected to the contact terminals 18 respectively. The data signal terminal 24 is surrounded or surrounded by a metal tube 22 provided in the insertion port 11 , the metal tube 22 having a generally square tube cross-sectional shape, and thus, the data signal terminal 24 is electrically shielded by the metal tube 22 . A metal pipe 22 is arranged in the resin molded body 14 , and is connected with a common terminal 26 of the charging connector 6 via a crimped contact metal piece 28 for the purpose of grounding. Regarding the connection between the metal tube 22 and the common terminal 26, as shown in FIGS. 2 and 3, the elastic pressure contact portion 28a of the crimping contact metal piece 28 is in elastic contact with the side surface of the extension portion 22a of the metal tube 22 to thereby be electrically connected thereto. . Regarding the connection between the crimping contact metal piece 28 and the common terminal 26, the insertion piece portion 28b of the crimping contact metal piece 28 is fitted into the clamping portion 26a of the common terminal 26 so as to be in crimping contact therewith.

In the connector 4 of this embodiment for the cellular phone 2, in the resin molded body 14 of the integral structure, the charging connector part 6, the headset connector part 10 and the data signal connector are arranged in this way. portion 8 such that the data signal connector portion 8 is arranged between the charging connector portion 6 and the headset 10 . Therefore, the connector 4 is interchangeable in external shape with existing connectors, and the data signal connector portion 8 can be added without changing the appearance, external shape and volume of the existing portable phone. Therefore, the space efficiency is improved, and a compact design can be realized, and furthermore, since the connector portions are integrally formed with each other, the assembly efficiency of the portable telephone 2 is improved.

The metal tube 22, the crimping contact metal piece 28, and the common terminal 26 of the connector 4 are connected together only by making them crimped to each other, so that soldering and the like are unnecessary, so that the assembly efficiency of the connector 4 is high. Furthermore, the elastic press-contact portion 28a of the press-contact metal piece 28 for press-contacting with the metal pipe 22 is formed in a convex shape so that it comes into press-contact with the metal pipe 22 reliably. Therefore, the metal tube 22 reliably shields the data signal terminal 24, so that data communication can be performed without being affected by noise. Furthermore, the grounding of the metal tube 22 is achieved by using both the common terminal 26 of the charging connector part 6 and the metal tube 22 , so that a compact design of the connector 4 can be achieved.

The connector of the present invention for a portable phone is not limited to the above-mentioned embodiments, and the data signal connector part does not always need to be provided between the charging connector part and the headset connector part, but only needs to be placed between the charging connector part and the headset connector part.
