Locking clip pin extender

The subject shunt connector has an integral housing of rigid insulative material and a single terminal mounted therein. The housing defines a pair of parallel, spaced male or pin terminal receiving passages extending between front and rear faces, and a slot interconnecting portions of the passages. The terminal has a pair of parallel contact arms interconnected at opposite ends by cross bars and a tine intermediate the arms. The terminal is so mounted in the housing that it can engage a pin terminal inserted from either face of the connector without being damaged or dislodged.

Shunt

Magnetic card reader

A low insertion force, handfed card reader is disclosed comprising a housing having a profiled passageway therein opening to a frontal side. The passageway is defined by a top wall having an array of contacts mounted therein, and a bottom wall slanted downwardly from a backward end of the passageway toward the frontal opening. A tray is provided within the passageway having a like-slanted bottom surface which is positioned against the bottom wall of the passageway. An encoded card can be freely inserted into the passageway a distance onto the tray, and as the tray is slid backward along the bottom wall, the encoded card is thereby moved upwardly against the contacts. A profiled retention spring system is further provided and pressures the encoded card against the top surface of the passageway to maintain the card reader in its read-mode until subsequently released by the user.

Low insertion force card reader

The invention relates to a card reader and to a novel connector for a plurality of printed circuit boards. In the connector a plurality of dielectric laminates are bonded together with electrical contacts arranged in rows. Printed circuit boards are insertable within pockets formed by the laminates. The spring contacts engage edges of the printed circuit boards. Elastomeric strips are compressed internally in the pockets to bias the contacts into electrical engagement with the printed circuit boards without a need for soldering the contacts to the boards. In the card reader, a read head incorporates the described connector and is mounted for displacement toward and away from an apertured encoded card. Displacement of the read head is produced by rotation of a shaft on which are mounted eccentric cams. The read head is provided with follower blocks which engage the surface of the cams. Upon rotation of the cams the cam followers are required to shift and allow the desired displacement of the read head toward and away from the card being read.
