An plug connector for electrical and mechanical connection to a mating plug connector has an outer conductor contact element and an inner conductor contact element. The inner conductor contact element has an inner-conductor-side contact region and the outer conductor contact element has an outer-conductor-side contact region. An inner-conductor-side contact plane is spanned by contact points of the inner-conductor-side contact region to contact a corresponding contact point of an inner conductor mating contact element. An outer-conductor-side contact plane is defined by contact points to contact a corresponding contact point of an outer conductor mating contact element. The inner-conductor-side contact plane and the outer-conductor-side contact plane are spaced apart in such a way that, in a plugged state of the plug connector and the mating plug connector, compensation of an electrical signal reflected in the inner-conductor-side contact plane by an electrical signal reflected in outer-conductor-side contact plane is attainable.

A connector including a shield case including a first shell and a second shell, a body housed in the shield case, and a terminal held by the body. The first shell includes a connecting portion of tuboid shape extending in a first direction, and a cover extending in the first direction contiguously from the connecting portion. The second shell is a separate member from the first shell and attached to the cover. The second shell and the cover constitute a composite tube extending in a second direction, which is orthogonal to the first direction, or in an oblique direction, which includes components of the first and second directions. The terminal includes a first portion, which extends in the first direction and is disposed inside the connecting portion, and a second portion, which extends in the second direction or the oblique direction and is disposed inside the composite tube.

A coaxial connector with an F female end shield is configured to restrict RF ingress.

An electrical connector includes contact pins, insulating housings for containing the contact pins therein and metallic outer contacts for respectively covering the housings. Each of the contact pins includes a horizontally extending portion, a contact portion, a connection portion, a downwardly extending portion and a press-fitting shoulder extending from a side portion of a base end portion of the horizontally extending portion in a width direction thereof. A width of the press-fitting shoulder of each of the contact pins decreases from a base side toward a tip side.

An example contact head includes coaxial contacts configured for transmission of radio frequency (RF) signals or digital signals between a test system and a device under test (DUT). Each of the coaxial contacts is configured to target a specific impedance. Each of the coaxial contacts includes a coaxial structure having an open-curve shape. The coaxial structure includes a spring material that bends in response to applied force and that returns to the open-curve shape absent the applied force. The coaxial structure includes a center conductor terminating in a contact pin and a return conductor separated by a dielectric from the center conductor. At least part of the center conductor and the return conductor include an electrically-conductive material. Flexible contacts on the coaxial contact include the electrically-conductive material.

A connector includes: an internal contact disposed at an inner position in a radial direction; an external contact disposed at an outer position in the radial direction; and an insulator disposed between the internal and external contacts. At least one of the internal and external contacts includes, on one side in the axial direction, a mating part to be mated with a corresponding counterpart contact at a predetermined radial contact pressure. The insulator includes a first insulator part exposed to the one side in the axial direction, and a second insulator part disposed on the other side in the axial direction relative to the first insulator part. The first insulator part is made of an elastic material capable of being easily deformed elastically in the radial direction as compared to the second insulator part.

A connector includes a female terminal module and a male terminal module that is to be coupled to the female terminal module.
