    • A noise suppressing connector comprises a shielding casing, first and second contact pins to be connected to external circuits, and a filter including at least one capacitor and a coil wound about a core made of a ferromagnetic material. An insulative housing is enclosed by the casing, and this insulative housing has a partition defining a bore with the inner wall of the housing. The first contact pin passes through the partition to project into the bore, while the filter is disposed in the bore to be connected between the first and second contact pins. At least one conductive plate is disposed in the bore and is connected to the casing for effectively shielding the filter and for serving as a ground circuit. The space in the bore may be filled with a suitable insulative material. The number of capacitors and coils may be increased to constitute a desired filter, such as a low-pass, high-pass or band-pass filter. With this provision noises which tend to pass through the connector are blocked, while induction and radiation of interfering waves and spurious waves are effectively prevented.
    • 噪声抑制连接器包括屏蔽壳体,要连接到外部电路的第一和第二接触引脚,以及包括至少一个电容器和缠绕在由铁磁材料制成的芯体上的线圈的滤波器。 绝缘壳体由壳体封闭,并且该绝缘壳体具有限定具有壳体的内壁的孔的隔板。 第一接触销穿过隔板突出到孔中,而过滤器设置在孔中以连接在第一和第二接触销之间。 至少一个导电板设置在孔中并且连接到壳体以有效地屏蔽过滤器并用作接地电路。 孔中的空间可以用合适的绝缘材料填充。 可以增加电容器和线圈的数量以构成期望的滤波器,例如低通,高通或带通滤波器。 通过这种设置,阻止了通过连接器的噪声,同时有效地防止了干扰波和杂散波的感应和辐射。
