Shielding Braid for an Assembled RJ Connector

A shielding braid can be subsequently mounted onto an assembled RJ connector, e.g. a RJ 45 connector. Normally the shielding braid is mounted on the cable before the actual assembly of the connector starts. The following describes a shielding member and a method to mount the shielding member without having to put the shielding member on the cable before the actual assembly of the connector.

Picture 1 shows an assembled RJ45 connector and picture 2 displays the shielding braid of this connector as single part as it is used now.

Picture 2: Shielding Braid as single part

The shielding braid contains a metal braid and a metal snapping construction in order to make an electrical interconnection with the connector. The shielded braid is formed out of two parts, e.g. two symmetrical parts.

The shielding member and the method described herein below enables one to mount the shielding member during the last assembly step.

In the following, three embodiments will be described:

Embodiment 1:

Picture 3 shows the symmetrical single part of a shielding member. A housing made out of plastic, can be made with a simple mould construction and a metal spring is made of sheet metal. Picture 4 shows the assembled shielding braid. The snap-fit device will secure a tight mechanical interaction with the cable. The metal spring inside the plastic housing will be compliant enough to overcome different diameters of different cables. The metal spring outside the plastic housing will snap on the metallic flap of the connector and make an electrical interconnection.

The strain relief will be obtained by means of a cable tie. The position of the cable tie can be seen in picture 5. The mechanical fixation of the metal spring into the housing can be made for example by using barb elements on the metal spring which will grab into the plastic housing, hot melt or insert moulding, etc.
