A contact includes a cantilever beam and a protection tab. The cantilever beam extends from a beam connected end to a beam free end along an insertion direction. The protection tab extends from a tab connected end to a tab free end in a direction opposite to the insertion direction. The tab free end is positioned adjacent to the beam free end.

A connector includes an insulator, a plurality of pairs of terminals provided on the insulator, and a resistance element. The plurality of pairs of terminals include at least one pair of cable terminals electrically connected with a cable and at least one pair of vacant terminals that are unused. The resistance element is electrically connected between each pair of vacant terminals.

A shield connector is provided with a housing including a module accommodation chamber and a terminal module to be inserted into the module accommodation chamber from behind the housing. The terminal module is formed such that an inner conductor is surrounded by a dielectric and the dielectric is surrounded by an outer conductor. The outer conductor includes a projecting portion projecting from a position rearward of a front end of the outer conductor on an outer surface of the outer conductor. An inner wall surface constituting the module accommodation chamber has a facing inner surface facing the outer surface formed with the projecting portion. The facing inner surface is formed with a projection-like backlash eliminating portion. The projecting portion is arranged behind the backlash eliminating portion with the terminal module inserted in the module accommodation chamber.

A connector connection structure includes: a first connector; a second connector electrically connected to the first connector; a unit to which the first connector is ground-connected; and a seal member sealing a gap between the first connector and the unit. The unit has a hole portion that includes a first portion and a second portion having a diameter smaller than a diameter of the first portion. The first connector includes shield shell provided with a contact portion having a contact part that is to abut an inner peripheral surface. A radius of the first portion is larger than a distance from a central axis of an electric wire of the first connector to a contact part in a neutral state. A core wire of the electric wire is electrically connected to a terminal portion of the second connector via a terminal portion of the first connector.

The invention relates to a plug-in connector, substantially consisting of an insulating body and at least one contact element which is mounted directly in the insulating body, wherein the insulating body directly forms the plug-in connector housing of the plug-in connector. The plug-in connector is of particularly simple construction and can therefore be manufactured quickly. In addition, the plug-in connector is of very robust design and suitable for industrial use, in particular in harsh environments.

A plug arrangement having a plug and a cable that is connected thereto and includes at least one inner conductor and an outer conductor surrounding the inner conductor(s); an axial terminal section of the outer conductor is electrically connected to a sleeve portion of an outer conductor housing of the plug, said sleeve portion surrounding the outer conductor; a crimp point comprising a radial constriction of the sleeve portion is located between the axial terminal section of the outer conductor and the axial end of the inner conductor in the longitudinal direction (L) of the cable.

A terminal module disclosed by this specification is provided with a shielded cable including two coated wires, a conductive shield portion for covering outer peripheries of the two coated wires and a sheath portion for covering an outer periphery of the shield portion, inner conductors to be connected to the coated wires, an insulating terminal accommodating member for accommodating end parts of the coated wires together with the inner conductors, and an outer conductor for accommodating the terminal accommodating member. An axis center β of a shield-side pull-out portion for pulling out the coated wires in the shield portion is radially shifted with respect to axis centers α of inner conductor-side pull-out portions for pulling out the coated wires in the inner conductors. A wire insertion path into which linking portions are insertable is formed in a lower wall of the terminal accommodating member.
