Abstract: The invention is directed to an electrical connector (2) for electrically connecting contact surfaces (74) of a daughter board (18) to contact areas (46) of mother board (34). The connector (2) has contacts (36) positioned therein, the connector (2) having posts (38) which extend from the connector (2) and make electrical engagement with contact areas (46) of the mother board (34). The daughter board (18) is then inserted into the connector (2) under reduced or zero insertion force conditions and rotated to its operating position. As this rotation occurs, contact projections (60, 72) of the contacts (36) engage the contact surfaces (74) of the daughter board (18). The rotation is translated into a positive wiping action between the contact projections (60, 72) and the contact surfaces (74), thereby ensuring that a positive electrical connection is effected. The resilient nature of the contacts (36) ensures that this wiping action occurs under normal force conditions. The configuration and characteristics, i.

Abstract: The invention relates to an automatic machine for shaping spectacle lenses, especially those in shatterproof material, with a bevel that serves to hold the lens in the frame. Lenses are copied from a pattern by three cutters which correspond to the three types of conventional bevel in current use; a positioning device stations the lens opposite the cutter giving the requisite bevel. Further devices adjust the position of the bevel in relation to the outer edge of the lens, and ensure that it follows the curvature of the individual lens while remaining at the right distance from the edge. The machine is a copier, and as such, utilizes a tracing mechanism for reproduction from the pattern lens; cam control is adopted for scaling the size of the copied lens up or down in relation to the pattern.

Abstract: A dry cell accommodating device includes a dry cell chamber, a cover and a dry cell holder. When a plurality of larger dry cells, for instance, size "AA" dry cells are accommodated, they are fitted into the interior of the dry cell chamber without any necessity for the dry cell holder. When a plurality of smaller dry cells, for instance, size "AAA" dry cells are accommodated, they are first held by means of the dry cell holder and the latter is then fitted into the dry cell chamber together with the dry cells. The device is provided with a mechanism for inhibiting an occurrence of incorrect fitting of the dry cell holder. The mechanism comprises a plurality of projections on the bottom of the dry cell chamber and a plurality of recesses formed at the lower part of the dry cell holder to be fitted over the projections when the dry cell holder is oriented in the correct direction. Further, the device is provided with another mechanism for inhibiting incorrect fitting of smaller dry cells.

The set of contact elements may include elements (367, 368) which form a switch (421).

Abstract: An interplane connector assembly for permitting in situ replacement of dual beam compliant contacts that are damaged or non-functional is provided. The interplane connector includes a support for receiving therein at least one row of dual beam compliant contacts and a cover. The cover is adapted to be releasably secured to the support and includes projecting stops that are displaced through a space between dual beams of the contact and received in an opening in the support that is disposed in alignment with the space between the dual beams so that the contact cannot be displaced from the support during insertion of the contact into a circuit board but yet so the contact can be removed and replaced when the cover is removed from the support.

Spring latch members (70) may be removable from plug connector modules (22) for repair.

Abstract: Aligning device for a current carrying connector of protective gas bag impact installations having a helical conductor arranged with several concentric windings within a fixedly mounted housing surrounding a core. The core is fastened to a steering spindle and rotates with the steering wheel. A first end of the helical strip terminates in terminals associated with the housing. The second end terminals are associated with the core. The core is equipped with a bore and the housing with a locking recess. The housing and the core may be immobilized in relation to each other using locking means having a clip pin insertable into the bore of the core and a locking projection fitting into the locking recess. The locking means may exhibit a ring surrounding the steering spindle and resting on the core or a pot surrounding a steering spindle. The locking recess and locking projection have respective widths which allow a slight rotational clearance between the core and the housing.

Abstract: Connector device having rod-like male and female contact sections of the same shapes to contact each other while they are arranged substantially parallel to each other. Contact section guide walls opposing each other are formed in the connector body. Rod-like contact sections are provided between the opposing guide walls. The proximal end of each contact section is fixed to the connector body and the distal end thereof is free to be elastically deformed. A contact projection is formed on the distal end of the rod-like contact section. An inclined portion is formed between the contact projection and a fixing section at the proximal end of the contact section.

Abstract: An electrical connector for a flat cable comprising a base housing (30) accommodating electrical contacts (50) and a cover housing (10) which is arranged to slide vertically with respect to the base housing. The cover housing and the base housing have grooves (11a, 11b) which mate with guide projections (31a, 31b) to guide the relative movement between the housings. The cover housing at a first position enables a part of a flat cable (1) to be positioned in an opening (45) of the base housing and upon movement of the cover housing to a second position, a projection (14) of the cover housing presses exposed conductors of the flat cable in engagement with the contacts. The cover housing can be maintained at its first position by a first locking means (31a) and at its second position by a second locking means (16, 37).

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.

Abstract: A distributor housing for communication cables in which the connecting unit for the individual wires is permanently integrated into a base component of the housing and the individual wires are first introduced into a positioning means in the contacting process. To form the connection, the pivotable top component of the housing, which has projection aligned with the various contact elements, is pivoted to a closed position to press the individual wires into their contact element.

Abstract: The contact elements of the plug connector are engaged into chambers of an insulating strip by means of a conductor terminal component which has cutting and clamping contact edges. The chambers are only open towards a flat side of the strip, so that a conductor can be pressed into the contacting slots of the cutting and clamping contact points from the open side of the chambers. This allows an uncomplicated, orderly connection of the conductor to the contact elements after the connection of the contact elements to the insulating strips. A plurality of such strips can then be inserted into a housing and combined with the latter to form a multi-row, e.g. three or four row, plug connector.
