Abstract

PROBLEM TO BE SOLVED: To reduce the number of part items and to sufficiently reduce the thickness of a device by providing an insulating body with a coaxial terminal for coaxial cable, surrounding a connection part and the coaxial terminal, electrically continuing an external contact to a shell, and forming the external contact of the coaxial terminal of an extended part of a part of the shell.

A coaxial contact of a coaxial terminal 5 and a center contact are connected to each other, so that external conductive pieces 9a, 9b of an external contact and a contact piece of the external contact are connected to each other in the coaxial terminal 5. At the same time, a lock claw of a lock arm is locked with a claw engagement hole of a shell 6, so as to lock the engagement of the compound connector 1 and the connector plug. A connection part of the center contact with the coaxial contact is shielded by the external conductive piece 9a and the shell 6.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for, for example, an interface of a portable telephone or the like. The present invention relates to a composite connector and a connector plug having thinned portions and a joint structure thereof.

[0002]

2. Description of the Related Art For example, in an interface for transmitting and receiving an electric signal between a portable telephone and a notebook personal computer, a connector for a low-frequency signal and a coaxial connector for a high-frequency signal are used together. It is known that the coaxial connector is provided as an independent type and provided near a connector for a low frequency signal.

[0003]

However, devices that emphasize portability are increasingly required to be lighter and thinner. Therefore, if the coaxial connector is a stand-alone type including a central contact for transmitting a signal and an external contact (also referred to as an external conductor) that surrounds and shields the periphery of the central connector, the coaxial connector is directly mounted on the device. There is a problem that a sufficient thickness cannot be achieved.

When a low-frequency signal connector and a high-frequency signal coaxial connector are integrally formed to form a composite connector, both connectors have a shield on the entire outer periphery of an insulator (housing) for supporting contacts. Is provided, and there is also a disadvantage that the shells having the same function are overlapped and the number of parts increases.

[0005]

The gist of the present invention for solving the above-mentioned problems of the composite connector according to the present invention is as follows: an insulator having a joint to be joined to a mating connector; and a front end facing the joint. A plurality of contacts disposed on the insulator, a coaxial terminal for a coaxial cable provided adjacent to the insulator near the joint, and a shell surrounding the joint and the coaxial terminal, An external contact for shielding in the coaxial terminal is electrically connected to the shell. Further, the external contact of the coaxial terminal includes a part of a shell extended.

[0006] The gist of the connector plug according to the present invention is that an insulator having a joint to be joined to a mating connector, and a front end facing the joint, and a rear end connected to a cable, are arranged on the insulator. A plurality of contacts, a shell surrounding the insulator, and a juxtaposition near the junction.
A composite connector having at least an external contact for shielding and a coaxial terminal for a coaxial cable including a center contact, wherein the external contact of the coaxial terminal includes:
It is a part of the periphery of the center contact and arranged substantially in line with the joint. In addition, the gist of the joint structure between the composite connector and the connector plug of the present invention is that a shell surrounding one of the insulators in the joint structure between the composite connector and the connector plug having the signal and coaxial joints on the insulator. Is extended to the joining portion to form a locking arm, a locking portion is formed at the distal end portion, and a locking release portion is formed on the way to the distal end portion. That is to say.

According to the composite connector of the present invention, when the low-frequency signal connector and the high-frequency signal coaxial connector are provided side by side on a single insulator and integrated, the external contacts of the coaxial connector (external contacts) The conductor) can be integrated with the low-frequency signal shell, so that the number of parts can be reduced and the connector can be made thin. Further, the shield performance of the coaxial connector is improved by being double shielded by the outer conductor and the low-frequency signal shell in the coaxial connector.

According to the connector plug of the present invention, since the external contact of the coaxial terminal does not surround the entire outer periphery of the center contact but only surrounds a part thereof, the entire plug can be made thin. Further, in the joining structure, the locking arm that locks when the connector plug is fitted and joined to the composite connector is easily unlocked by the unlocking portion.
