[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a modular connector used for telephones, computers, and the like, and more particularly to a connector having a chip connector mounted on a plug-side connector.

[0002]

2. Description of the Related Art FIGS. 15 to 19 show a conventional receptacle 8.
20 to 25 show an example of a conventional plug 9 connected to the receptacle.

As can be best seen from FIGS. 15 to 19, and in particular from FIG.
The receptacle contact 81 loaded therein extends rearward from the mating surface of the plug, and is formed obliquely such that the closer the contact portion 81a extends in the extension direction of the receptacle contact 81, the closer to the plug at the time of mating. This is a modular connector used in recent years with a lock that connects the board 85 and the cable. Since it is used by general users, it can be moved in a relatively large fitting direction in the locked state at the time of fitting. This is because the fitting and the locking can be performed even with a simple fitting operation.

On the other hand, as shown in FIGS. 20 to 25, a plug 9 is provided on an upper surface of an insulator 90 in a groove 9 in a longitudinal direction.
1 are formed at a predetermined pitch interval. These grooves 9
1, a plug contact 93 is loaded in the groove 91.
Is formed so that a space is left in the upper part. In such a configuration, when the receptacle 8 and the plug 9 are fitted and connected, the receptacle contacts 81 are pressed by the plug contacts 93 while being aligned in the pitch direction while being regulated by the grooves 91, so that the receptacle 8 and the plug 9 are electrically connected. Connecting. In the figure, reference numeral 95 denotes a lock lever at the time of fitting connection with the receptacle 8.

In recent years, when there are a plurality of types of devices connected to the opposite side of the plug of the cable, only the connector is fitted and connected, and the device connected to the receptacle is determined. The electronic identification is performed.

[0006]

However, when identification is performed in the device on the receptacle side as described above, an identification circuit is provided in the device on the receptacle side, and the device on the plug side and the identification circuit on the receptacle side are further connected. Must be connected. For this reason, the core for the identification circuit must be separately provided in the cable, and the number of cores increases by that much, and the diameter of the cable must be increased, and the cost of manufacturing the cable increases. Have.

[0007] In order to prevent such a cable from having a large diameter, there is a connector in which a chip component for identification is mounted on a connector. However, in the case of a conventional connector on which chip components are mounted, the contacts must be soldered to a substrate on which chip resistors are mounted. That is, when the chip component and the contact are directly connected, the configuration is simplified by arranging the pitch direction of the electrode and the contact of the chip component in the same direction. However, since chip components are large in the direction of the electrodes, there has been a problem that the size of the connector has to be necessarily increased.

The technical problem of the present invention is to reduce the size of a connector having a function of identifying a connected device without increasing the number of cores of a cable in view of the problem of the conventional technology, and to reduce the manufacturing cost. An object of the present invention is to provide a connector with an inexpensive chip component.

[0009]

[0011]

[0012]

According to the present invention having the above-described structure, the electrode of the chip component such as a resistor mounted on the plug can be connected to the corresponding contact of the receptacle when the receptacle is connected to the plug. This makes it possible to identify the type of device on the receptacle side by changing the characteristic value (resistance value) of the chip component for each type of device connected to the opposite side of the cable plug.

The above-mentioned chip component is generally in the shape of a rectangular parallelepiped, is manufactured so as to be soldered to a substrate by surface mounting technology, and is so small that it is difficult to hold it by hand so as to take up space. is there. However, in consideration of good handling and direct connection to contacts, a relatively large chip component is selected.

Further, the spring portions of the pair of plug contacts which are in conductive contact with the chip component are configured to be displaced in the pitch direction of the connector, and the chip contact portions of these plug contacts are perpendicular to the pitch direction and the fitting direction. If the contacts are arranged at predetermined intervals in the pitch direction, the longitudinal direction of the electrodes will be the direction of mating and unmating of the connector, so that the displacement of the contacts will be large. acceptable.

Further, when the chip component has a rectangular parallelepiped shape,
If the electrode pitch direction, which is the long side, is perpendicular to the connector pitch direction, it is possible to prevent the size of the connector from becoming extremely large due to the mounting of chip components.
