A connection arrangement (4, 4′) of two components (1, 2) according to the invention has a curved surface portion having a contact point on at least one of these components. The curved surface portion can extend over the entire surface of a groove, for example. The other component has a taper. When assembling the two components before a force is applied, a line connection is created from the 2-contact point connection and when force is applied, the line connection changes through plastic deformation into a strip connection, on the basis of which the two components (1, 2) hold together.

A device is for fixing equipment to an end of the inner surface of a tube. The device has an elongated body, a ring adapted to surround and slide along a segment of the elongated body, and at least two flaps rotatable on the ring. Each hole in the elongated body is adapted for bearing a bolt aligned with the longitude of the elongated body. The ring has at least two threaded bores designed to mate with the threads of the bolts so that the position of the ring on the elongated body is controllable by applying torque to the bolts; and the flaps are positioned homogenously around the ring. The elongated body has at least one portion adapted to guide the flaps so that the flaps radially open against the inner surface of the tube.

A hub mounted grease cap having a sleeve with an inner end and an outer end. The outer end has an outer end surface that is opposite the inner end. The sleeve encloses a bore that extends through the sleeve. The inner end has an outer diameter that may be a press fit or threaded connection to a hub into which it is installed. An end plug has an end wall and an aperture through the end wall. There is a shaft that extends through the aperture in the end wall of the end plug. A wedge block is connected to the shaft. A seal has a portion that is located between the end wall of the end plug and the wedge block. The seal expands radially outward against the bore of the sleeve when the wedge block is drawn toward the end wall.

A quick connect assembly having a male terminal with a plurality of circumferentially arrayed and elongated beams including forward-most arcuate projecting and outer diameter defining portions. A female terminal has a housing exhibiting an inner diameter inlet communicating with an interior arcuate and expanded extending recess which matches a profile defined by the outer diameter beam portions. A forwardly spring biased plug is displaceably supported within the female terminal housing and includes a forward most projecting snout portion which, upon installation of the male to female terminals, the projecting snout portion of the plug seats between the male beams, preventing unintended collapse and remove of the male beams from within the female housing.

A mounting device for an elongate member, comprising: an elongate housing having an elongate axis; an internal passageway passing through the elongate housing parallel to the elongate axis; an elongate sleeve located within the internal passageway and being configured for longitudinal movement along the passageway; a plurality of ball-receiving recesses in the wall of the internal passageway, each recess having a ball-guiding surface inclined to the longitudinal axis; a plurality of apertures in the sleeve; a ball located in each of the ball-receiving recesses and engaged with a respective aperture in the sleeve, the balls and the apertures being configured to allow the balls to project partially through the apertures but to prevent balls from passing through; biasing means configured to bias the sleeve in a direction to urge the balls to project radially inwardly through their respective apertures in the sleeve and into the internal passageway.

A refrigerant-channel branching component for connecting a connection pipe connected to an outdoor unit with a connection pipe directed toward a plurality of indoor units, the refrigerant-channel branching component includes: an inlet portion; and outlet portions. At least one of the plurality of outlet portions includes: a reference space into which a reference connection pipe with a predetermined outside diameter is inserted; a first space that is adjacent to the reference space and has an inside diameter greater than an inside diameter of the reference connection pipe; and a second space that is adjacent to the first space and has an inside diameter greater than the inside diameter of the first space.

A joint exhibits high tensile strength. The joint includes a solid rod having a slit or opening into which a wedge is inserted. The rod and wedge are inserted into a fitting. Only a small amount of adhesive material is applied between the fitting and the rod. The adhesive material may be blended with non-adhesive, non-compressible “beads” that have a preferred diameter in order to insure that the desired adhesive thickness is achieved between the fitting and the rod. The internal surface of the fitting has a contour which continuously and nonlinearly varies with distance along the fitting. The wedge has a dimension having a similar contour. The shape of the contour can be described by a polynomial of order two or higher. The joint can be used to construct a sucker rod for an oil well, or it can be used in other applications. The joint can support high tensile loads, over long distances, while occupying a very narrow tubing bore.

A first embodiment of a torque tube coupler may include an outer body that includes a first abutting surface and a second abutting surface adjacent to the first abutting surface. Set screws may be inserted into one or more channels of the first abutting surface. Tightening the set screws may force the abutting surfaces away from each other and the outer body to press against an inner surface of a torque tube. Another embodiment of the torque tube coupler may include a central ring sized based on a size of a torque tube. The torque tube coupler may also include a set of fingers that extend away from a first side of the central ring and are shaped to flex radially outward. The torque tube coupler may include a core disposed within the set of fingers that, when drawn towards the central ring, causes the fingers to flex radially outwards.

A drop wire clamp to secure a cable that comprise an outer shell and an inner wedge. The outer shell having a first wall, a second wall, and a shell base to couple the first wall with the second wall. The shell base further defines a shell channel. The inner wedge is receivable in the outer shell and movable between a first position and a second position within the outer shell. The inner wedge has a wedge base defining a wedge channel, wherein the shell channel aligns with the wedge channel in the second position to form a containment structure to house a cable therein. The containment structure includes a length dimension and a width dimension, wherein the length dimension is greater than the width dimension and the length dimension extends in a same direction as the first wall and second wall of the outer shell.

A tension rod has an outer shaft slidably receiving an inner shaft. A tension mechanism includes a partially threaded rod with a threaded portion. A first end extends from the threaded portion and is adapted for fixing to an inner surface of the inner shaft; a second end has a tapered body with a greater transverse dimension closer to the second end. A wedge has a slot and an inner surface in facing sliding engagement with the tapered body between a nut threadedly engaged with the threaded portion and the second end. The nut is rotationally fixed to the outer shaft. Upon relative rotation of the inner and outer shafts, the nut moves along the threaded portion toward the second end, the wedge abutting and moving with the nut. The wedge contacts the tapered body, expands radially, and contacts the inner surface of the outer shaft, locking the shafts together.
