Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a connector device having a signal processing function.

[Prior Art] An example of a conventional connector device is shown in FIG.

The connector device 51 comprises a connector C and a housing H, to which a cable L is connected.

The housing H is formed of resin in such a shape that the connector C can be attached and the wiring side portion of the connector C can be covered.

Each terminal of the wiring side portion of the connector C is soldered to each core wire of the cable L, and this portion is covered and protected by the housing H.

FIG. 8 shows an example of the use of the above-mentioned connector device 51, which is an RS for connecting a data terminal (DTE) and a line termination device (DCE).
Used for 232C cable.

[Problems to be Solved by the Invention] The conventional connector device 51 is used together with a cable such as an RS232C cable when connecting different devices such as DTE and DCE to each other. It is necessary to check the electrical specifications, mechanical specifications, and also the logical specifications of the signal system, and match them.
It was complicated. Further, since the cable serves as an antenna and radiates noise radio waves, there is a drawback that other electronic devices are adversely affected.

Further, although it has only a simple function of "connection", its size is relatively large, and there is a problem that the space utilization efficiency is low.

Therefore, the purpose of this invention is to eliminate the complexity of using a cable and to eliminate the drawback of noise radio wave emission.
An object of the present invention is to provide a connector device which has a built-in signal processing function and improves space utilization efficiency.

[Means for Solving the Problems] A connector device according to the present invention comprises a connector for connecting to another device, a circuit module including a circuit for processing a signal transmitted through the connector, and the connector wiring side portion. A housing for covering the connector, the connector mounting contact portion having a shape to which the connector can be attached and the terminal can be brought into close contact, and the circuit module holding contact portion having a shape to accommodate and hold the circuit module and to be brought into close contact with the terminal And a housing formed with a wiring pattern for connecting a portion that can be in close contact with the terminal of the connector and a portion that can be in close contact with the terminal of the circuit module. It is a thing.

[Operation] In the connector device of the present invention, the circuit module is housed and held in the housing, and a wiring pattern is formed on the housing itself to connect the terminal of the connector and the terminal of the circuit module. Therefore, it is not necessary to carry out internal wiring with wires, and it is possible to make the size extremely small and to reduce the number of manufacturing steps. Moreover, since it has a signal processing function by itself, it eliminates the need for conventional cables,
No complication or noise emission problem. Further, since the function is enhanced, the space is used more efficiently.

[Embodiment] Hereinafter, the present invention will be described in more detail with reference to an embodiment shown in the drawings. The invention is not limited to this.

A connector device 1 with a built-in signal processing function of one embodiment of the present invention shown in FIG. 1 is a 25-pin D-SUB connector C and modular jacks J1 and J2, a CPU module board B1, a modem module board B2 and a line interface module board. It is equipped with B3 and a housing H.

The housing H covers the wiring side portion of the 25-pin D-SUB connector C, and the 25-pin D-SUB connector C
And a connector mounting contact portion Ha having a shape capable of being closely attached to the terminal. Further, it has a connector mounting contact portion Hb having a shape capable of mounting the modular jacks J1 and J2 and being in close contact with the terminals thereof. Also, CPU
The module board B1, the modem module board B2, and the line interface module board B3 are housed and held, and the circuit module holding contact portions Hc, Hd, and Hd are shaped so as to be in contact with their terminals. Further, the connector mounting close parts Ha, Hb and the circuit module holding close parts Hc, Hd, H
A wiring pattern P for connecting with d is formed.

As shown in Fig. 2, the structure of the connector mounting contact portion Ha is
There are through holes h through which each terminal of the 25-pin D-SUB connector C passes, and wiring patterns P are provided in these through holes h.
Has a structure that is guided respectively.

The structure of the connector mounting close part Hb is
It is similar to the structure of.

As shown in FIG. 3 (a), the structure of the circuit module holding contact portion Hc has a groove m into which the CPU module board B1 is fitted, and the conductor of the wiring pattern P wraps around the groove m. ing. As shown in FIG. 3B, when the CPU module board B1 is fitted into the groove m, the wiring pattern P comes into contact with the conductor Q of the board B1 and is electrically connected.

As shown in FIG. 4 (a), the structure of the circuit module holding contact portion Hd has a slot u into which the modem module board B2 and the line interface module board B3 are inserted, and the conductor of the wiring pattern P is inserted into the slot u. It has a structure that wraps around. As shown in FIG.
After inserting B1 and B2 into the slot u, solder between the board B1 and B2 and the tapered portion t of the slot u (F in the figure),
Both will be connected.

The wiring pattern P in the housing H can be formed by two-color molding (or two-shot molding). That is, as shown in FIGS. 3 and 4, first, a catalytic resin is injection-molded to form a catalytic resin portion H1, and then a non-catalytic resin is overlaid and injection-molded to form a non-catalyst. The conductive resin portion H2 is formed, and a conductor layer is further formed on the surface of the catalytic resin portion H1 by electroless plating to form the wiring pattern P.

FIG. 5 is a side view of the connector device 1 described above, in which the speaker S is also incorporated.
