Abstract: A codable kink protection is formed such that this forms an interference-fit connection with a coding sleeve. The coding means are provided with a through slot, thus allowing the coding sleeve to be pushed over the cable and the flexible bush. The coding sleeve is made of an elastic colored plastic and is shaped essentially complementary to the kink protection housing, in order to achieve a form-fit connection therewith. This coding sleeve can be applied and removed without necessitating special tooling and is excellently visible from all viewing angles.

Abstract: A cable terminal contract assembly (3) encompasses two spaced apart tongues (4) with contact springs (7) exhibiting contact points (8), wherein the longitudinal edges of the tongues are intended for the insertable, positive meshing with guide grooves of one of the chambers of a multiple-connection strap. The tongues (4) exhibit wire connecting means at the free end, insulation-piercing connecting devices (5), and are connected on the inner end by a web (6) with a narrow width. The contact assembly is a through contact that is transformable into a separating contact by separating the web, or into a switching contact by inserting an isolating piece or via molding. The connection strap casing can be produced as a one-piece plastic body.

Abstract: With connectors of a plug connection for high-frequency data transmission via several twisted electrical conductor pairs in a cable, the conductors at the cable end are separated by undoing the twist and then connected via wire connection means to contacts. The individual conductors of the conductor pairs directly at the cable exit are in a set sequence and are guided parallel in two planes at a set distance from each other in a contact housing (11) of non-conducting material that can be installed in the contact plug, and they are preferably connected there to the relevant contacts (1′-8′) via an insulation displacing connecting device (9′) in an IDC contact element (9).

This ensures that the connection ends of optical waveguides which are readily manufactured as male connectors can be used directly for modular electric connector systems such as RJ 45 or RJ 11.

Housing components which hold the plugging and/or socket connectors are joined by an articulated joint. The plugging and/or socket connectors are connected by a band-shaped flexible printed conductor foil (20) with a number of parallel printed conductors, with printed conductor sections of the printed conductor foil providing direct plugged contacts of the plugging and/or socket connection.

Abstract: The contact set of a plug connector part such as a contact plug or a contact jack for high frequency data transmission over electric conductors comprises a row of contact points for connecting to corresponding contact points of the mating component of the plug or jack which are connected over conductors with insulation piercing connecting devices. At least adjacent conductors (1, 2) are arranged so they wrap around one another at a predetermined distance in their common plane between the insulation piercing connecting devices (11, 12) and the contact springs (21, 22) forming the contact points for compensation of the capacitive and inductive coupling.This avoids crossover and recrossing in different planes, but now a type of crossing is achieved in a plane common to all conductors. In addition, both the capacitive and the inductive coupling can be compensated effectively and equally beyond the 300 MHz range.

At least two insulation displacement contacts are located within the contact mount. Each displacement contact has an insulation displacer region formed on an end thereof. An arrangement is provided for gripping both an incoming wire and an extending wire inserted into the assembly. The arrangement is movable to press a selected wire into the respective insulation displacer region when the assembly means is pressed downward toward the contact mount, to form a disconnectable through-connection of the incoming and outgoing wires.

The slits for receiving wires are provided with lateral retaining projections arranged above one another. At least one retaining projection is located near the spot where the wires are inserted for the purpose of positioning the inserted wire, and the other retaining projection is located near a region of the insulation displacer for the purpose of fastening the wire which is pressed into the insulation displacer.

This trough can be bent towards the contact spike by stripping the cable with a cable binder.
