摘要:
A coupling device serves for the contact-free transmission of data signals between signal conductors of two signal lines with the aid of a coupling structure. At least one signal conductor is a signal core of a signal cable. Coupling portions of the two signal conductors are positioned parallel in relation to one another in a defined way with the aid of the coupling structure. At least a first signal conductor preferably being free from galvanically connected coupling elements lies in a coupling aid. The contact-free coupling dispenses with connecting additional coupling elements at the ends to a signal cable in an electrically conducting manner. By obviating the need for special connector fabrication, this achieves the effect of simplifying assembly and at the same time also improving data transmission reliability, since faults that occur for example in a crimping or soldering process are ruled out.

Apparatus and method for a radially attachable RF trap attached from a side to a shielded RF cable. In some embodiments, the RF trap creates a high impedance on the outer shield of the RF cable at a frequency of RF signals carried on at least one inner conductor of the cable. In some embodiments, an RF-trap apparatus for blocking stray signals on a shielded RF cable that has a peripheral shield conductor and a inner conductor for carrying RF signals includes: a case; an LC circuit having a resonance frequency equal to RF signals carried on the inner conductor; projections that pierce and connect the LC circuit to the shield conductor; and an attachment device that holds the case to the cable with the LC circuit electrically connected to the shield conductor of the shielded RF cable.

An electrical connector system for communication or power transfer between a two connectors in which the first of the two connectors may be inserted into a receptacle of a second connector in order to align a coil within the first connector with a coil within the second connector to promote inductive communication between the first and second connector. In many embodiments, at least one of the two coils may also be used as a spring, providing a mechanical force. The mechanical force may assist in joining or separating the connectors. For example, the spring coil may be used in conjunction with a push-push mechanism to retain the first connector within the second connector and to eject the first connector when the connectors should be separated.
