Abstract

Ferrite elements are known to filter noise or unwanted disturbance signals out of signal lines. For this purpose ferrite elements are placed around the signal wires or around terminals in connectors that are known in the art. But the implementation of the ferrite elements sometimes requires elaborate construction of the connector housing furthermore some additional working steps are necessary to assemble the connector to the wire harness. An easy to assemble modular connector with a frequency noise attenuation and cheap to produce is desirable. The disclosed connector housing provides, beside means to hold the terminals, also a ferrite insertion space wherein a ferrite block is hold. The ferrite block has openings for passing through the signal wires. The wires are surrounded by the ferrite material when the connector is in use. Because the ferrite insertion space in the housing has a shape that allows the insertion of the ferrite element only in one position a wrong insertion is impossible. A first embodiment of the invention is shown in figure 1. Figure 1 shows a connector and a ferrite element with a rectangular shape. The ferrite element has a cut-out that corresponds with a rib in the ferrite insertion space. A second embodiment of the invention discloses a male header with a ferrite insertion space. The ferrite block has a shape that fits into the insertion space in the housing. When in the correct position, the ferrite block is hold by flexible arms. Figure 2 shows a ferrite element used in this embodiment. Figure 3a and 3b show an explosive view of a header. Figure 4a and 4b shows the ferrite assembly process into the connector. Figure 4c shows an assembled ferrite block in a cut view. Figure 4d and 4e shows a perspective view of an assembled header. A third embodiment shows a ferrite element that is hold in an additional housing (Figure 6a) that is attachable to the connector (figure 5). The ferrite element is made of two parts (Figure 6b). These embodiments can be used for connectors that are already integrated in a wired system (e.g. a car). Whereby the ferrite element and the additional housing is arranged around the signal wire. Figure 7 shows the ferrite assembly process into the additional housing.

Connector design with frequency noise attenuation effect

Background of the invention

Ferrite elements are known to filter noise or unwanted disturbance signals out of signal lines. For this purpose ferrite elements are placed around the signal wires or around terminals in connectors that are known in the art. But the implementation of the ferrite elements sometimes requires elaborate construction of the connector housing furthermore some additional working steps are necessary to assemble the connector to the wire harness. An easy to assemble modular connector with a frequency noise attenuation and cheap to produce is desirable.

Description of the invention

The disclosed connector housing provides, beside means to hold the terminals, also a ferrite insertion space wherein a ferrite block is hold. The ferrite block has openings for passing through the signal wires. The wires are surrounded by the ferrite material when the connector is in use. Because the ferrite insertion space in the housing has a shape that allows the insertion of the ferrite element only in one position a wrong insertion is impossible.

A first embodiment of the invention is shown in figure 1. Figure 1 shows a connector and a ferrite element with a rectangular shape. The ferrite element has a cut-out that corresponds with a rib in the ferrite insertion space.
