An assembly includes a first member having an inner surface and a second member having an outer surface. One of the two members has greater rigidity than the other member and at least one groove. The rigid member is partially received within the less rigid member and a coupling mechanism provides radially inward pressure to generate a seal between the inner surface of the first member and the outer surface of the second member. The groove includes an opening and a base each having a predetermined width. The predetermined width of the opening is generally less than the predetermined width of the base. The more rigid member may comprise an insert with a surrounding sleeve wherein the sleeve includes the grooves.

Hose and tube assembly

A coupling assembly includes a female member having a bore and a male member capable of being received in the bore of the female member. A trigger assembly is disposed between the male and female members and includes an actuator, housing, and biasing member. The male member includes an engagement mechanism to engage the trigger assembly and facilitate axial movement of the actuator. Axial movement of the actuator induces expansion of the biasing member and the engagement of the actuator and the male member. Accordingly, the male member is urged or propelled into the bore of the female member upon expansion of the biasing member. To disconnect, the male and female members are utilized to return the trigger assembly to an inactivated position.

Coupling assembly

The preferred field assembly includes a field shell of generally T-shaped radial cross-section and molded of powdered metal, a plastic bobbin for supporting a multiple turn winding, and a plastic bobbin ring which covers part of the field shell and which helps hold the bobbin in assembled relation with the field shell. The bobbin is formed with a terminal block for supporting electrical leads which extend along grooves in the outboard face of one flange of the bobbin and which, together with the end portions of the winding, extend into potting cavities in the outboard face of the bobbin flange. The bobbin ring includes a cap which interfits with the terminal block to retain the leads. Various embodiments of field shells, bobbins and bobbin rings are disclosed.

Field assembly for an electromagnet

An apparatus for precisely winding a coil of wire, either free standing or on a bobbin, includes a servo motor for rotating a spool and a wire feeding mechanism for guiding the wire onto the rotating spool. The wire feeding mechanism is mounted on a ball screw shaft connected to a stepper motor. Thus, rotation of the ball screw shaft by the stepper motor causes axial movement of the wire feeding mechanism. A wire feed angle sensor is provided on the wire feeding mechanism for generating a signal which is representative of the load angle at which the wire is wound upon the spool. A control system, such as a microprocessor or a programmable controller, is responsive to the load angle signal for controlling the operation of the stepper motor and, thus, the position of the wire feeding mechanism relative to the point of winding on the spool. As a result, a constant load angle is maintained throughout the winding process. A wire diameter sensor also generates signals to the control system. The control system is responsive to the wire diameter signal for determining the number of windings which can be made on each layer of the spool. In an alternate embodiment, the control system determines the position of a movable flange in accordance with the diameter of the wire to provide a predetermined number of windings per layer.

Apparatus for precisely winding a coil of wire

A mold locator is adapted to support and position a wound electromagnetic coil within a mold for encapsulation of the coil by dielectric media. In one preferred form, the locator includes an annular central body having arms extending radially from the central body. In addition to having a pair of stiffening ribs extending along the sides thereof, each arm incorporates a channel for carrying a wire lead. The central body is annular in shape and defines an interior wall having a plurality of radially extending detents adapted to make point contacts with a centering arbor in the mold. Similarly, each radially extending arm of the mold locator incorporates at least one detent adapted to make a point contact with the floor or bottom of the mold cavity. Collectively, the detents operate to limit surface contact between the locator and the internal surfaces of the mold.
