A holding and contacting device is disclosed. In an embodiment a holding and contacting device includes a cage defining a cable path through the cage and a spring element protruding into the cable path and configured to apply a clamping force onto a cable placed along the cable path, wherein the spring element and the cage comprise a metal.

A communication device includes a mechanical frame, which is configured to be inserted into a multi-channel Small Form-Factor Pluggable (SFP) receptacle that is compliant with a first SFP standard and to receive inside the frame an SFP connector that is compliant with a second SFP standard, which is different from the first SFP standard. First electrical terminals, held by the mechanical frame, are configured to mate with respective first pins of the SFP receptacle, and second electrical terminals, electrically coupled within the mechanical frame to the first electrical terminals, are configured to mate with respective second pins of the SFP connector. A heat sink is mounted on the mechanical frame and configured to make a positive contact with the SFP connector when the SFP connector is inserted into the mechanical frame and to be contained completely within the SFP receptacle when the mechanical frame is inserted into the SFP receptacle.

A contact insert of a spring force connection clamp having at least one retaining frame and at least one clamp spring that is mounted in the retaining frame, wherein a spring insert that functions so as to increase the clamping force of the clamp spring is arranged at least within a region that is encompassed by a spring bow of the clamp spring, wherein the spring insert is configured as one piece with the retaining frame. A spring force connection clamp having at least one contact insert of this type is also provided.

The terminal block includes a movable operation feeling generating member (60) which generates an operation feeling according insertion of a conductor portion into an accommodating portion (12) from a first opening portion (111), and a first protruding portion (63) disposed in the accommodating portion to be capable of coming into contact with the movable operation feeling generating member being rotated by the insertion of the conductor portion into the accommodating portion from the first opening portion after the conductor portion and a terminal electrode portion (20) are changed from the non-connected state to the connected state. The movable operation feeling generating member includes a first contact portion (61) capable of coming into contact with the conductor portion inserted into the accommodating portion, and a second contact portion (62) which has a second protruding portion (70) generating the operation feeling by coming into contact with the first protruding portion (63).
