Abstract

A connecting and latching mechanism in an electronic apparatus is activated by a portion of the housing of a complementary electronic device as it is inserted for interconnection and charging. Varying sizes of devices can be accommodated. Three rotatable elements, two pawls and a connector arm, are mounted on a single base plate. One pawl keeps the connector arm from being damaged before device insertion and helps position the device upon insertion. A connector block on the connector arm is rotated into position for contacting the terminals of the device by a second portion of the device housing. When the connector block is in full contact with the terminals, the connector arm is latched by another pawl. A lock must be deactivated by key or manually operated button to release the latching pawl, the connector arm and the inserted device. Rotatable charging contacts provide scouring motion at the contact points and also accommodate devices of varying lengths.

Claims

1. A connector arrangement for an electronic apparatus having means for receiving an inserted electronic device, the arrangement comprising in combination:

an arm member rotatably mounted and biased into a first position in the apparatus and including contact means, positioning means for positioning the inserted device relative to the contact means, and first and second shoulder portions, the first shoulder portion engaging a projecting portion of the inserted device, as the device is inserted, for causing rotation of the arm member into a second position, said rotation bringing the positioning means and, subsequently, the contact means into engagement with mating contact portions of the inserted device;

enabling means having a first position for preventing rotation of the arm member, and movable by insertion of the electronic device to a second position wherein the arm member is able to rotate, the enabling means being biased into said first position; and

latching means having a projecting portion for engaging the second shoulder portion of the arm member for releasably retaining the arm member in the second position.

2. A connector arrangement according to claim 1 and further including a support member mounted within the apparatus, and wherein the arm member, enabling means and latching means are mounted on the support member.

3. A connector arrangement according to claim 1 and wherein the arm member comprises a lever and wherein the distance from the axis of rotation of the arm member to the first shoulder portion forms a first lever arm portion and the distance from the axis of rotation to the contact means forms a second lever arm portion, the second lever arm portion being longer than the first lever arm portion.

4. A connector arrangement in accordance with claim 1 and further including locking means mounted on the apparatus for releasing the latching means from a latched condition.

5. A connector arrangement in accordance with claim 1 and wherein the enabling means is rotatably mounted on the support member.

6. A connector arrangement in accordance with claim 5 and wherein the enabling means has first and second extended portions, the first portion being engaged and moved from the first position by a portion of the inserted device, the second portion being simultaneously moved from the first portion, thereby allowing the arm member to rotate.

7. A connector arrangement in accordance with claim 1 and wherein the enabling means and the latching means are rotatably mounted.

8. A connector arrangement for an electronic apparatus having means for receiving an inserted electronic device, the arrangement comprising in combination:

first contact means for connecting operating circuitry of the inserted device to operating circuitry of the apparatus, the contact means providing a locking function for the device within the apparatus;

second contact means for connecting charging circuitry of the inserted device to a corresponding charging current source in the apparatus; and

means for biasing an inserted device against an inner portion of the apparatus.

9. A connector arrangement in accordance with claim 8 and wherein the first contact means includes fixedly retained contacts on a rotatably mounted arm member, means for retaining the arm member in a first inoperative position when no device is inserted into the apparatus, and for enabling rotation of the arm member to a second operative position upon device insertion.

10. A connector arrangement in accordance with claim 9 and further including latching means for retaining the arm member in the second position and means for releasing the latching means.

11. A connector arrangement in accordance with claim 10 and further including key means for enabling the releasing means.

12. A connector arrangement for an electronic apparatus having means for receiving an inserted electronic device, the arrangement comprising in combination:

contact means rotatably mounted within the apparatus in the path of the device for mating with contact means on the first inserted surface of the inserted device, the contact means of the apparatus being biased into a position substantially perpendicular to the contact means of the device, as the device is being inserted and the inward movement of the device contacts against the apparatus contacts causing rotation of the apparatus contact means for causing scraping motion by the apparatus contacts on the device contacts.
