An electronic wireless locking system comprising an external assembly and an internal assembly disposable on respective sides of a door or drawer. The external assembly includes a cover housing, a knob having a shaft, a card/credential reader, a status indicator, a wireless communication capability, a wire harness and a jump port plug. The internal assembly comprises a rotation link matable with the external shaft, a latch bolt, a circuit board and controller, and a locking mechanism including a rack and pinion gear set linking the rotation link with the latch bolt. A blocker inhibits the latch bolt from unlocking until authorized to rotate 90°, permitting the latch bolt to be withdrawn from a strike plate by manual rotation of the knob. An optional mechanical key override feature may also be provided. The system may further include a preload sensor and a device locked sensor.

1. An electronic lock system for securely locking a door or drawer, comprising: an external assembly mountable to an external surface of said door or drawer; andan internal assembly mountable to an internal surface within said door or drawer and electrically connectable to said external assembly,wherein said external assembly includes a first circuit board, a rotatable actuator and attached shaft,wherein said internal assembly includes a motor assembly, a second circuit board, a locking mechanism including a latch bolt and a latch bolt sleeve supportive of and operatively connected to said latch bolt wherein said latch bolt is movable relative to said latch bolt sleeve, a rotatable link for receiving said shaft and operatively connected to said latch bolt sleeve, and a blocker operatively connected to said motor assembly and rotatable by said motor assembly between a blocking position wherein said latch bolt sleeve is blocked from movement and a non-blocking position wherein said latch bolt sleeve is not blocked from said movement. 2. A system in accordance with claim 1 wherein said internal assembly further includes an actuator rotation switch, wherein said actuator rotation switch and said motor assembly are operatively connected to said second circuit board. 3. A system in accordance with claim 1 further comprising a card/credential reader and an antenna connected to said first circuit board. 4. A system in accordance with claim 1 further comprising an attachment between said external assembly and said internal assembly, wherein said external assembly may be positioned at any of a plurality of rotational orientations with respect to said internal assembly. 5. A system in accordance with claim 1 further comprising: a strike plate associated with said internal assembly, wherein said strike plate includes a magnet; anda magnetically sensitive switch disposed in said latch bolt that provides a signal to said second circuit board indicative of a correct locking position of said latch bolt with respect to said strike plate. 6. A system in accordance with claim 5 wherein said magnetically sensitive switch is a reed switch. 7. A system in accordance with claim 1 wherein a rack and pinion gear set connects said rotatable link to said latch bolt sleeve. 8. A system in accordance with claim 7 further comprising a connecting arm operatively connecting said latch bolt sleeve to said latch bolt. 9. A system in accordance with claim 1 wherein said blocker is capable of rotation through about 90° between said blocking position and said non-blocking position. 10. A system in accordance with claim 9 further comprising a mechanical key override feature comprising a cam lock rotatable by a key, wherein said cam lock is configured to move said latch bolt relative to said latch bolt sleeve when said latch bolt sleeve is blocked from said movement. 11. A system in accordance with claim 10 wherein said latch bolt and said latch bolt sleeve move telescopically in a coordinated manner such that said latch bolt and said latch bolt sleeve move together or said latch bolt moves independently of said latch bolt sleeve, thereby permitting unlocking of said latch bolt by said mechanical key override feature. 12. A system in accordance with claim 1 further comprising a switch contactable by said latch bolt sleeve and movable by said latch bolt sleeve between a first switch position and a second switch position wherein, when said switch is in said second switch position, a signal is sent by said switch indicative of a preload on said rotatable actuator, and movement of said blocker said motor assembly is deferred until said preload is removed, and wherein, when said switch is in said first position, movement of said blocker by said motor assembly is not deferred. 13. A system in accordance with claim 1 wherein said internal assembly includes a battery for powering said motor assembly. 14. A system in accordance with claim 13 wherein said external assembly further comprises a port for attaching an external power source to power said motor assembly. 15. A system in accordance with claim 1 wherein said system is configured to transmit encrypted communications between said external assembly and said internal assembly.
