A connection for a feed line at a feed pump pumping fuel out of a fuel tank, includes a nonreturn valve disposed in a horizontal portion of a connection stub. The connection stub is held on the feed pump by a latching device. The connection permits a particularly compact configuration of the feed pump.

A connection of two components is disclosed that abut on the faces thereof. With this connection, it is possible to create a stable connection, particularly of flat components, with a high level of precision of the position with regard to one another and with a preferred accessibility in the space around the plane extending from the adjacent adjoining faces of the components. Both components each have a half borehole with encircling collars; a fastening device that extends through the complete b...

A connection device of a computer connector comprising a clip piece composed of a metal spring leaf and a press-button fixed onto said metal spring leaf, and an insertion socket in the shape of long sheet provided in the clip hole on the side of the shell of the connector stand wherein, in the central portion of the metal spring leaf of the clip piece, two corresponding protrusions in the form of "["-shape sheet is stamped in order that the clip piece will be inserted into the insertion socket i...

A connection bearing with a line connection comprises an annular bearing body with a through-opening which receives a bearing pin. The connection bearing has a receiving channel for receiving a line penetrating the connection bearing. The receiving channel is constructed at least up to the annular bearing body. Therefore, one end of the line can be grasped to hold it in a coaxial arrangement relative to the longitudinal axis of the connection bearing. The receiving channel in the bearing body fo...

The invention relates to a connection method and a connection arrangement. The solution employs an adapter fastener, which is intended for both an adapter connection and a circuit board connection, the adapter fastener being electrically conductive. The adapter fastener comprises a hole, which extends through the adapter fastener and to which a coaxial cable is fixed. The sheath of the coaxial cable is electrically connected to the adapter fastener and a male connection is formed at the adapter ...

A connection for flow of a fluid, comprising first and second bodies, female and male connection elements that are respectively pivoted on the first and second bodies and hollow and complementary such that the male connection element may be seated within the female connection element, and wherein an angle of pivoting of each of the male and female elements is limited relative to a median position thereof.

A connection nipple for providing fluid communication with the interior of the container, such as for example a blood bag or the like. The connection nipple comprises a hollow tubular member having a first end which is adapted to be sealingly inserted within the blood bag and a second open end disposed externally of the blood bag. A circumferential rib member is provided circumferentially about the hollow tubular member intermediate the first and second ends. The circumferential rib has a cross-...

An electric connector comprising two connector plates, each of said plates having opposite inner sides provided with toothed zones the teeth of which penetrate the insulation when clamping the connector plates toward each other. The clamping force is applied to the outer sides of the connector plates through plate springs at points located opposite the toothed zones.
