A pin contact for an electrical connector is disclosed having a contact body and a pin. The contact body is formed from a metal sheet and has a mating end, a pin receiving space and an offset wall. The pin receiving space extends inward from the mating end. The offset wall has at least one welding region, and an outer surface facing away from the welding region and accessible from the outside. The pin is positioned in the pin receiving space and projects out of the mating end. The pin is welded to the welding region.

A shielded connection line for a magnetic resonance tomography system includes a signal conductor, a shield for the signal conductor, and a plug-in connector. The plug-in connector has a large number of connection contacts that are arranged in a two-dimensional matrix and are electrically insulated from each other in the plug-in connector. The signal conductor is in galvanic contact with a first connection contact, and three second connection contacts adjacent to the first connection contact and surrounding the first connection contact are galvanically connected to the shield.

A connector includes a female-side connector and a male-side connector including an inner engagement portion and an outer engagement member or portion. The outer engagement member or portion has: an outer engagement member or portion body covering the female-side engagement portion from outside when the male-side connector is inserted into the female-side connector; and has a holder that, when the male-side connector is inserted into the female-side connector, covers the screw thread on the female-side engagement portion from outside, and fills a gap between the female-side engagement portion and the outer engagement member or portion body. The holder is disposed on an end portion side of the male-side connector from the inner engagement portion in a longitudinal direction of the male-side connector, and disposed so as to pinch the female-side engagement portion in cooperation with the inner engagement portion when the male-side connector is inserted into the female-side connector.

An abutting portion is provided as a portion of an edge portion of an upper wall portion, and abuts against an edge portion of a first side wall portion when the upper wall portion bends toward the inside of a tubular wall portion. The projection portion projects from the upper wall portion, and restricts insertion of the tubular wall portion toward the back of the housing by abutting against the housing when the tubular wall portion is inserted into the housing in an orientation different from a predetermined insertion orientation. The engaging portion is configured to be able to engage with an engaged portion provided on an inner side of the housing. The engaging portion is provided on the tubular wall portion at a position that shifted from or separated from the projection portion in the longitudinal direction of the tubular wall portion.

Spring-loaded contacts having an improved reliability. One example may provide spring-loaded contacts having a reduced likelihood of entanglement between a spring and a plunger. For example, a piston may be placed between a plunger and a spring. The piston may have a head portion that is wider than the diameter of the spring and located between the spring and the plunger to isolate the spring and the plunger. In these and other examples, an additional object, such as a sphere, may be placed between the plunger and spring. In another example, two additional objects, such as two spheres, may be placed between a plunger and piston.

A connector component is disclosed. The connector may include an electrically-conductive clamp element configured to clamp a contact element to a surface element. The surface element may be electrically-conductive and may be inserted into the clamp element using a recess in a lateral edge of the surface element to provide additional surface area for an electrical connection. The clamp element may be a lamella contact. The surface element may be at least one contact blade. The clamp element may include two laterally-spaced clamp elements. The connector component may also include a contact element that is inserted into the two clamp elements.

A connection structure of terminals according to the present invention includes an elastically-deformable first connector, to which a motor wire is electrically connected, an elastically-deformable second connector, to which a driving circuit wire is electrically connected, and a conductive portion, which electrically connects the first connector with the second connector. The first connector and the second connector are joined to the respective end surfaces of the conductive portion. The first connector is elastically deformed to hold the motor wire with its own restoring force. The second connector is elastically deformed to hold the driving circuit wire with its own restoring force.
