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.

An inventive cable fitting (1) for high voltage cables, comprises a rigid core insulator (5) with a central duct suitable to receive a high voltage cable conductor. An elastomeric stress relief element (8) is cast around and thereby attached to a first part of the rigid core insulator (5). The stress relief element (8) comprises an insulating volume (9) made of elastomeric material, a field deflector (11) and a shield electrode (10). The stress relief element (8) is arranged so that it can receive a high voltage cable.

A connecting apparatus comprising a holding member and a conductive member. The holding member has holding portions. The conductive member has a plurality of held portions, a plurality of contact portions, a plurality of extending portions and a plurality of coupling portions. Each of the extending portions extends rearward in a front-rear direction from one of the held portions and protrudes rearward in the front-rear direction beyond the holding portion. The extending portions are positioned apart from each other in a right-left direction. The coupling portions are positioned apart from each other in the right-left direction. The coupling portions are positioned rearward of the extending portions in the front-rear direction. Each of the coupling portions couples two of the extending portions with each other. Two of the held portions, which are adjacent to each other in the right-left direction, are coupled with the two extending portions, respectively.

A connector manufacturing method includes: a first insertion process of inserting a conductor held by a housing through an annular seal member; a second insertion process of inserting the conductor through an annular portion of a support member; a pushing-in process of pushing the seal member into a gap between an inner circumferential surface of a recess in the housing and the conductor by pressing the seal member using the annular portion; and an engagement process of making the annular portion support the seal member at a predetermined position by engaging the support member and the housing, wherein the predetermined position is a position before a bottom portion of the recess.

A sensor apparatus for wellbore applications includes an electrical conductor extending within an armored tubular jacket to protect the electrical conductor. The electrical conductor is isolated from wellbore fluids when the sensor is placed in a wellhead flange by redundant seals such that the tubular jacket around the conductor does not provide a leak path to the surrounding subsea or surface environment. To isolate the electrical conductor, a connector housing may be provided that establishes a glass-metal seal or a PEEK-metal seal with the electrical conductor. The connector housing may be welded or otherwise sealed to a Christmas tree flange that connects to the wellhead flange. The welds and seals of the sensor apparatus may be proof tested to ensure their effectiveness before the Christmas tree flange is installed in the subsea or surface environment.

A vehicle charge port assembly includes a housing having a port configured to couple to a charge-station coupler. The port includes a plurality of terminals and a back cover attached to a back side of the housing and defining openings that receive the terminals. The port further includes wires, each joined to one of the terminals, and seals each encircling one of the wires and disposed in a corresponding one of the openings.

Apparatus and methods for inserting and retention testing an electrically conductive contact in an electrical connector. The method includes the following steps: manually partially inserting the contact into a hole formed inside the electrical connector; inserting the contact further into the hole by pushing the contact along an axis using an insertion tip that is aligned with the axis and that displaces in a first direction along the axis during inserting; and after inserting the contact further into the hole, testing retention of the contact inside the electrical connector by pushing the contact along the axis using a test probe that is aligned with the axis and that displaces in a second direction opposite to the first direction during retention testing. The force exerted by the test probe on the contact is less than a specified contact retention force. The method further includes generating an alert signal if the test probe displaces along the axis in the second direction by more than a specified distance during retention testing.

A connector housing for an electrical connector includes a receiving portion arranged inside a cavity of the connector housing. The receiving portion is adapted to receive an electrical contact terminal. The receiving portion further comprises at least one latching nose adapted to block a release movement of the electrical contact terminal upon insertion of the electrical contact terminal into the connector housing. The connector housing comprises a reinforcement element made of a material different than the material of the connector housing. Said reinforcement element is arranged on a surface of the connector housing and adapted to reinforce at least a part of the connector housing in a region around the at least one latching nose. The present disclosure further relates to a connector assembly for an electrical connector.

A protective device for electrical conduits including a body having a lower opening for engaging with a first conduit and a central cavity for receiving conductors extending from the first conduit to a second conduit, a top member having an upper opening for engaging with the second conduit, and a coupler slidably engaged around the body, the coupler slidable between an open position distal to the top member and a closed position attached to the top member.
