Abstract: This invention relates to electrical connectors and more particularly to electric connectors for propagation of a relatively large number of signals between electrical circuits and at very high velocities. The number of signals which can be propagated is quite large in relation to the size of the connectors of the invention and at the same time, the signals can be transmitted at very high velocity and with minimal interference between the signals propagated or from external signal sources. The connectors are also advantageous in that the electrical characteristics of the propagation paths are uniform and they can be readily matched to the characteristics of the circuits which are interconnected so as to minimize standing wave phenomena. The invention also facilitates connection to a plurality of circuit board circuits while providing substantially complete separation of signals propagated to and from the circuits.

Abstract: A low light loss expanded beam fiber optic connection is provided comprising lensed optical connector pins. Each connector pin employs a cylindrical housing in which a fiber end is precisely located along a longitudinal axis in precisely spaced relationship with an adjacent ball lens. The center of the ball lens is coaxial with the longitudinal axis of the optical fiber core and is maintained in such precisely spaced relationship by means of a spacer engaging the ball lens and the fiber end on opposed surfaces. As a result of the precise relationship, light emanating from a fiber end is disposed at the focal point of the adjacent ball lens for transmission to an adjacent, axially aligned lensed optical connector pin of similar construction.

Abstract: An electrical connector including a first box element and a second box element, each box element receiving an electrical contact and the other box element when one of the box elements is inverted head-to-tail upside down with respect to the other box element. Each element includes male and female portions. The male portion includes a locking lug having an elastic portion and a stiff rounded portion. The female portion includes a joggle. The joggle of each element is adapted to engage the locking lug of the other element during assembly of the first and second elements along an insertion axis. When this occurs the joggle will climb up the stiff rounded portion of the locking lug thereby displacing the first and second elements in opposite directions perpendicular to the insertion axis. Further displacement along the insertion axis displaces the joggle into contact with the elastic portion which bends, so as to displace the two elements closer to each other perpendicular to the insertion axis.

Each compartment includes an aperture to receive an electrical contact device, a locking device for engaging the electrical contact device to lock the contact device in the compartment, and a lug having a portion that is sufficiently steep to prevent the electrical contact device from passing over this portion of the lug when the electrical contact device is inserted into the compartment in a position different from a normal insertion position. Also provided is a barrier which consists of a ramp connected to the steep portion of the lug. In the normal insertion position the electrical contact device passes over the ramp and lug to be locked in the compartment, whereas in a position different from this normal insertion position the electrical contact device abuts the steep portion of the lug and cannot fully enter the compartment or engage the locking device.
