Abstract: A system for conductively charging a motor vehicle includes a charging device and a receiving device. The charging device has an electrical contacting unit and a lifting device operable, for axially moving the contacting unit between retracted and extended positions. The receiving device has a receiving chamber for receiving the contacting element inserted therein when the contacting element is moved to an extended position. The contacting unit has a cylindrical or truncated cone body and includes an electrical contact ring extending around a lateral surface of the body of the contacting element. The receiving device includes a radially position-able electrical contact element along the receiving chamber. When the contact element is in one radial position while the contacting unit is inserted into the receiving chamber the contact element electrically contacts the contact ring and mechanically fixes the contacting unit to the receiving device inside the receiving chamber.

Abstract: An electrical plug connector includes a housing and a plug contact. The housing includes a housing body and a housing part which together form the housing with a receiving chamber therein. The housing body and the housing part are movable relative to one another perpendicularly to a plug-in direction and can be stably fixed to one another in a pre-locking position and in an end-locking position. The plug contact is connected to an electrical connection line and has a detent spring. The plug contact is inserted along the plug-in direction into the receiving chamber. The housing part has a locking arm having a detent protrusion. The detent spring engages the detent protrusion after the plug contact is inserted into the receiving chamber in the pre-locking position. The locking arm fixes the plug contact in the receiving chamber in a form-fit manner in the end-locking position.

Abstract: A charging system for charging an electric vehicle at a charging station includes a charge module at the charging station and a charge module at the vehicle. The charge modules include electric contact elements which can be interconnected together. The charging system includes an automatic positioning device configured to move the charging station charge module relative to the vehicle charge module to align and join the charge modules together. The charging system includes an automatic feed device configured to enable the contact elements of the charging station charge module to connect to the contact elements of the vehicle charge module when the charge modules are joined together. The contact elements of the charge modules are configured such that the contact elements can connect to each other without overriding a contact force.

Abstract: A contact element for connecting to a cable having a braided shield includes a spring contact sleeve and a crimp sleeve. The spring contact sleeve has an annular ring and spring contacts arranged circumferentially on one end of the annular ring. The spring contact sleeve and the crimp sleeve form an enclosed hollow cavity between one another when the crimp sleeve is joined to the annular ring. The hollow cavity is configured to fully receive therein an exposed portion of the braided shield provided for connection of the contact element to the cable.

Abstract: A block fitting for an air conditioning system includes a male block portion and a female block portion. The male block portion has a first annular pilot. The female block portion has a first annular collar that receives the first annular pilot of the male block portion. The first aperture of the male block portion and the first aperture of the female block portion are substantially concentrically aligned. A first seal structure is disposed between the first annular pilot of the male block portion and the first annular collar of the female block portion. A fastener engages the male block portion with the female block portion to form a substantially fluid tight seal. One of the of the male block portion and the female block portion has a stabilizing heel formed adjacent a side surface thereof. The stabilizing heel militates against transverse dynamic loading of the seal structure in operation.

Abstract: A crimp fitting for a hose member including a nipple and a socket coupled thereto. The nipple has an outer surface provided with a plurality of axially extending reverse angled first barbs and a plurality of axially extending forward angled second barbs alternatingly formed thereon. The first barbs are configured to engage an inner surface of a hose member to increase a sealing engagement between the nipple and the hose member, and the second barbs are configured to engage the inner surface of the hose member to militate against a disengagement of the nipple from the hose member.

Abstract: The method produces a reshaped glass-ceramic article by forced reshaping of a flat green glass part during a ceramicizing process with temporarily lowered viscosity due to crystallization heat. To perform the forced reshaping economically the forced reshaping takes place in a continuous oven for ceramicizing and in an oven section in which the viscosity of the green glass part is temporarily lowered as a result of crystallization heat. An apparatus for performing the process is provided in the continuous oven including different active reshaping devices and/or a hollow mold. The method produces glass-ceramic articles with undamaged surfaces corresponding to surfaces produced during the making of the green glass part (smooth or structured, e.g. knobbed).
