Problems solved by technology

[0003] However, most known solutions suffer from the disadvantage that they are not robust enough to withstand vibrations and temperature changes in automotive applications
Furthermore, in many cases the connection between the shielded cable and the shield of the housing, for example, has too high a resistance
On the other hand, soldered connections make assembly more difficult and expensive

Embodiment Construction

[0035] figure 1A partially exploded view of FIG. 2 shows a connector for a shielded cable 100 according to a first embodiment of the present invention. The shielded electrical cable 100 includes a center conductor 102 separated from a surrounding shield braid 104 by an insulating layer 106 . The cable jacket 108 insulating the shielded cable 100 is removed, exposing the shield braid for contact by the shield termination structure 110 of the present invention.

[0036] The center conductor is electrically contacted by terminal 112 . However, the particular shape of the terminal 112 is not relevant to the shield termination structure of the present invention.

[0037] According to the invention, a shielding body 114 is provided, which is formed as a convoluted piece, for example from aluminum. In the connection region 116, the shield body 114 can be brought into contact with the shield braid 104 to connect the shield body 114 to the figure 1 The interface 118 is shown as a s...

Abstract

The present invention relates to shielded electrical cables and shielded electrical connectors to be affixed thereto, and in particular to the termination of the shielding braid provided at the electrical cable. According to the present invention, a shielding termination structure for engaging a shielding (104) of a shielded cable (100) having an insulated conductor (102) that is encompassed by said shielding is provided, said shielding termination structure (110) comprising: an electrically conductive shield body (114) for establishing an electrical connection between said shielding (104) and an electrically conductive interface (118), fixing means (126) for securing said shield body (114) at the interface (118); an electrically conductive spring element (120) that is arranged between said shield body (114) and the interface (118) for establishing the electric contact in a compressed state of the spring element (120).

Description

technical field [0001] The present invention relates to a shielded cable and a shielded electrical connector affixed to the shielded cable, and more particularly to a shielded braided termination provided on the cable. More specifically, the invention can be applied to sealed electrical connections, which are necessary, for example, for automotive applications. Background technique [0002] When terminating a shielded electrical cable, the shield braid of the cable is typically electrically coupled to an electrical connector or shielded component of an electronic device. One way to achieve this coupling is to attach the braid directly to the shield by welding or soldering. Another approach is to include a crimp ring that fits over the braid of the cable and can be crimped towards the braid of the cable to positively hold the braid. After crimping, the crimp ring must be connected to the connector shield. A radially expanding elastic element may be used to establish the co...
