Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connector with a filter used as a noise filter for high frequencies.

[0002]

[Prior art]

 In this kind of electronic equipment, the filter circuit is usually composed of resistors and capacitors, and such electronic parts were externally connected to the terminal part of the output end of the noise filter using a solder.

In this case, there is a problem that the work is complicated because individual electronic components such as resistors and capacitors are soldered and connected one by one.

In addition, it is preferable to connect the pins to a position as close as possible to the pin terminal, but in actuality, when the legs of the electronic component are entwined with the pin terminal for connection, the electronic component is slightly separated from the pin terminal. When it is located at such a position and is separated from the pin terminal in this way, the inductance becomes large, and there is a problem that it is difficult to obtain desired characteristics as a noise filter due to the influence.

The present invention has been proposed in view of the above points, and an object of the invention is to provide a connector with a filter in which electronic components are built in advance and which has a small inductance and is not affected by the influence. It is in.

[0006]

[Means for Solving the Problems]

 The present invention achieves the above object by preliminarily connecting the electronic component 3 forming the filter circuit to the root of each pin terminal 2 and molding the resin component 4 in the mold.

[0007]

In the present invention, as described above, the electronic parts 3 forming a filter circuit such as an inductor (coil) or a resistor or a capacitor are connected to the base of the pin terminal 2 in advance, and the electronic part 3 is molded with the resin 4. Then, the filter-equipped connector 5 is manufactured integrally. Then, it suffices to insert the pin terminal 2 of the connector 5 with a filter into the pin terminal insertion portion of the output end of the power supply device, thereby improving workability.

Further, since the electronic component 3 is connected to the root of the pin terminal 2 and is not located at a position apart from the pin terminal 2, the inductance can be reduced and the electronic component 3 is not affected by it.

When the electronic component 3 is connected to the substrate 1, the workability is good, that is, the electronic component 3 is easy to attach and can be surely connected.

When the electronic component 3 and the substrate 1 are molded with the resin 4, the moisture resistance is improved and the attachment / detachment can be easily performed, and the workability of attachment / detachment and the durability of the product are good.

【Example】

 FIG. 1 shows an embodiment of the present invention. In the figure, 1 is a plate-shaped substrate, 2 is a pin terminal implanted through the substrate 1, and 3 is an electronic device such as a capacitor which is connected between a predetermined pair of pin terminals 2 and constitutes a filter circuit. It is a part. Since this electronic component 3 is mounted on the substrate 1, it is connected between the roots of the pin terminals 2 so that the workability of the connection is good and the inductance does not increase. Reference numeral 4 denotes a molding resin such as epoxy resin. The base portion of the substrate 1, the electronic component 3, and each pin terminal 2 is molded by the resin 4 and integrally molded, and the end portion of the pin terminal 2 is molded. A connector 5 is formed which is provided so as to project from the sleeve body and has a filter circuit built therein.

FIG. 2 shows another embodiment of the present invention. In this example, pin terminals 2 are planted on the front and back of the substrate 1, a capacitor C is connected between predetermined pin terminals 2, and an inductor L is connected between one pin terminal 2 and another pin terminal 2. Alternatively, the resistor R is connected, and these electronic components 3 form a filter circuit. The other structure is the same as that of the above-mentioned embodiment.

The connection points of the electronic component 3 are not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention. It is also possible to place the pin terminal 2 and the electronic component 3 in the mold without using the substrate 1 and inject the resin 4 and mold them to manufacture a connector with a filter. In this case, The number of parts can be reduced.

[Effect of device]

 As described above, according to the present invention, the electronic parts 3 constituting the filter circuit are pre-connected to the roots of the pin terminals 2 and molded by the resin 4, and the electronic parts are retrofitted to the pin terminals. The workability is good because it does not exist, and since the electronic parts are connected to the root of the pin terminal, the influence of the inductance can be reduced.
