JP2003151377A - Connector, multi-cable provided with connector and attaching method for tag - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a connector with a tag housed in a heat contraction tube and provide a multi-cable attached with an inexpensive tag not obstructing work and never falling off. SOLUTION: A transparent heat contraction tube 22b is used as the heat contraction tube arranged in a rear end side of a connector body 22a, and the tag 22c is arranged in its interior. Falling off of the tag is prevented by contracting the transparent heat contraction tube by heat. Each cable can be easily discriminated by using the connector in connection of the multi-cable such as a twin cable.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector and a multi-cable provided with the connector, and more particularly to a connector and a multi-cable provided with the connector that allow easy identification of the cable.

2. Description of the Related Art Currently, in the United States, digital radio broadcasting (frequency, about 2.3G) using artificial satellites (broadcasting satellites) is used.
Hz) is about to start. Development of a digital radio receiver for receiving this digital radio broadcast is under way.

There are two types of digital radio receivers. One is to directly receive the radio waves transmitted from artificial satellites (hereinafter also referred to as "satellite waves"), and the other is to receive the radio waves received by the ground station that received the radio waves from the artificial satellites. It receives radio waves that are shifted in frequency and broadcast (hereinafter also referred to as "terrestrial waves").

A digital radio receiver of the type that directly receives satellite waves is supposed to be mounted on a mobile body such as an automobile. However, since satellite waves are easily affected by the weather, it is desirable that the digital radio receiver mounted on the mobile body can receive not only satellite waves but also terrestrial waves. However, satellite waves are circularly polarized waves, while terrestrial waves are linearly polarized waves. Therefore, in order to receive both satellite waves and terrestrial waves, dedicated receiving antennas are required.

When two receiving antennas for satellite waves and terrestrial waves are mounted on a mobile body, these are often installed in one place for various reasons. Further, the received signals received by these two receiving antennas are both sent to the same receiver body and demodulated. For this reason, conventionally, when a digital radio receiver of this kind is mounted on a moving body, in order to connect the antenna device including two antennas and an amplifier connected to these and the receiver body,
A twin cable is used in which two cables are integrated so as to be parallel to each other.

FIG. 1 shows a conventional twin cable 10. The twin cable 10 shown in FIG. 1 includes two cables (coaxial cables) 11 integrated so as to be parallel to each other.
And a connector 12 connected and fixed to one end of each.

Further, the twin cable 10 is provided with a scooping bush 13 attached at a position spaced apart from the connector 12 and the other end portion for fixing the twin cable 10 to an antenna device (antenna). And a cable bushing 14 attached in the vicinity.

The connector 12 is a receiver body (not shown).
A connector body 12a that fits into another connector (input terminal) provided in the connector, and a heat-shrinkable tube 12b that is combined with the connector body 12a to reinforce the mechanical strength between the connector body 12a and the cable 11. Have

When the connector 12 is fitted into the connector on the receiver main body side, it is necessary to supply the reception signals received by the two antennas for satellite wave and terrestrial wave to the corresponding input terminals. In other words, it is necessary to be able to easily determine which cable is for satellite waves and which cable is for terrestrial waves.

As one method for enabling such discrimination,
There is a method to change the shape of the connector. However, this method causes an increase in the number of parts and an increase in cost. Therefore, conventionally, a method of attaching the tag 15 to each cable 11 has been adopted as a method of further suppressing an increase in cost.

[0011]

Although the conventional cable identification method of attaching a tag to a cable is inexpensive, the attached tag sticks out to the side and is used at the time of shipping or attaching work. Not only is it a hindrance, but it also has the problem that it becomes dirty and indistinguishable, or it falls into pieces.

The present invention provides a connector for accommodating a tag in a heat-shrinkable tube, and thus provides a multi-cable with a tag attached, which is inexpensive, does not interfere with work, and does not fall off. To aim.
