A banana-shaped cage adapted for use as an intervertebral fusion cage, wherein the leading direction of the nose of the banana cage is substantially in-line with the angle of the inserter shaft that inserts the cage into the disc space. It has been found that insertion of this cage requires lower insertion forces than the conventional cage whose leading direction substantially follows the arc of the banana curve.

A high temperature electrical connector suitable for use in a high temperature gas sensor. The electrical connector incorporates a ceramic connector body having a pair of opposing ceramic body portions which each house a plurality of conductive terminals. The body portions are in pivoting engagement and fixed in a connector body retainer which also enables their pivoting, hinged movement. The pivoting engagement permits the ceramic body portions and terminals to hinge open to receive a gas sensor with a low insertion force and a hinge closed to provide the desired contact force. The ceramic body portions may also include a taper section in a pivot portion with a taper angle that may be varied to control the pivoting, hinged movement of the electrical connector.

A socket connector for connecting a bulbous terminal or ball wherein the female element grips the terminal with resilient prongs with end tips at low insertion force but positive contact is maintained and wherein attempted withdrawal is normally inhibited by increasing force applied to the post by the female element in response to the withdrawal force. The female element comprises a tube of resilient conductive material that has been sliced or helically partitioned into opposing prongs of a width that decreases with axial distance from the end of the connector so as to allow the prongs of the connector to grip around the ball-like bulbous terminal and mechanically retain the terminal within the connector. The tubular element of the connector may be made by forming prongs in one or both ends of a tube by cuts of a width that increases with distance from the end of the tube.

A socket connector for connecting a post or ball wherein the female element grips the post with resilient prongs with end tips at low insertion force but positive contact is maintained and wherein attempted withdrawal is normally inhibited by increasing force applied to the post by the female element in response to the withdrawal force. The female element comprises a tube of resilient conductive material that has been sliced or helically partitioned into opposing helical prongs so as to allow the prongs of the connector to spirally open around the post or ball-like bump and mechanically grip the post or bump as the post or bump is inserted along the longitudinal axis of the tube. The tubular element may be made by forming helical prongs in the end of a tube in helical cuts from about a mid section to one end of the tube.

When an insertion force of a rotary tool 340 has searched, it is made clearly that the force at the insertion initial time is large and when a friction stir joining is an ordinary operation time, the force becomes small. According, it is preferable to make small the insertion force at the insertion initial time. To members 20, 30 to be subjected to a joining at a position where the friction stir joining starts a hole 50 is opened, and this hole 50 after the rotary tool 340 has inserted, since a move of the rotary tool 340 is made to begin, a lowering of the insertion force can be attained.

A low-insertion force electrical connector for implantable medical devices. The electrical contact includes a housing with a pair of opposing sidewalls each with center openings oriented generally concentrically around a center axis. The housing also includes a recess with a recess diameter. An inner coil is located in the recess with a coil axis generally co-linear with the center axis of the center openings. The inner coil includes an outer diameter less than the recess diameter, and an inner diameter greater than a center opening diameter. An outer coil is threaded onto the inner coil to form a generally toroidal-shape. The outer coil has an outer diameter less than the recess diameter, and an inner diameter less than the center opening diameter. The outer coil is radially expanded within the recess in response to engagement with contact rings on the implantable medical device, such that the outer diameter of the outer coil is at least equal to the recess diameter.

A probe having a flexible, small diameter fiber sheathed in a small diameter flexible tube comprising the distal tip of the probe. The small diameters of the fiber and tube allow the fiber to be bent in a tighter radius along essentially the entire length of the exposed portion of the fiber, with low tube bending forces during insertion, providing a compact design which eliminates the need for a straight distal portion. The small diameter tube also allows a greater wall thickness outer cannula to be used, thereby increasing instrument rigidity. This compact, rigid design with low insertion forces allows the fiber greater access to the internal posterior structures of the eye, while providing increased instrument rigidity for manipulation of the eye, as well as low insertion forces.

A ball socket for connection with a ball stud resists accidental pull-out of the ball stud. The ball socket achieves relatively low insertion force but relatively high pull-out force resistance.

A method for producing scalable, low cost, reliable, compliant, low profile, low insertion force, high-density, separable and reconnectable interposer for high speed, high performance electronic circuitry and semiconductors. The method can be used to make, for example, electrical connections from components such as a Printed Circuit Board (PCB) to another PCB, MPU, NPU, or other semiconductor device. A normalized working range for an array of elastic contacts of the interposer can be about 0.2 to 1.0. A reversible normalized working range is maintained through multiple connections and reconnections using a highly elastic material for the contact arms. In one aspect, a first electrical component having a first array pitch can be connected to a second electrical component having a second array pitch.

In some embodiments, the present invention provides an independently tightening collet surrounding each socket for each of a plurality of corresponding high-electrical-power prongs, wherein the collet is loosened for normal (low-insertion-force) insertion and withdrawal of the plug from the outlet. Once the plug is inserted, the collet is tightened, providing a high-contact force to lower the contact resistance and to help keep the plug from coming unplugged. In some embodiments, the plug is not “locked”, in that a tension force pulling on the plug will overcome the contact force at a point before the plug or outlet is damaged, and the plug is allowed to come unplugged. In some embodiments, engaging the collet will also provide a wiping or sliding motion between the prong and socket for each connection, thus wiping at least some dirt or corrosion away and providing a lower-resistance better electrical contact.
