Abstract

Various connection interfaces are disclosed. In some embodiments, the connection interface includes a receptacle and a connector. The receptacle can be configured to be positioned in the wall of an electrical device. The receptacle can comprise a first set of electrical contacts and a channel. The connector can be configured to be matingly engaged with the receptacle in an engaged state and to be separated from the receptacle in a disengaged state. The connector can comprise a second set of electrical contacts. Some embodiments are configured such that angled surfaces of the channel and boss interact as the connector is moved into engagement with the receptacle. This can guide the connector into the receptacle such that the first and second sets of electrical contacts are in electrical communication with each other.

Claims

1. A connection interface comprising:

a receptacle configured to be positioned in a wall of an electrical device, the receptacle comprising;

a first set of electrical contacts; and

a channel comprising a first angled surface, the first angled surface being at a non-parallel and non-perpendicular angle with respect to a longitudinal axis of the connection interface; and

a connector configured to be matingly engaged with the receptacle in an engaged state and to be separated from the receptacle in a disengaged state, the connector comprising;

a second set of electrical contacts; and

a boss comprising a second angled surface, the second angled surface being at a non-parallel and non-perpendicular angle with respect to the longitudinal axis of the connection interface, wherein the boss projects longitudinally beyond, and extends around to circumscribe, the second set of electrical contacts;

wherein the first and second angled surfaces are configured to interact as the connector is moved into engagement with the receptacle, thereby guiding the connector into the receptacle such that the first and second sets of electrical contacts are in electrical communication with each other; and

wherein the first and second angled surfaces are at an angle, relative to the longitudinal axis, of about 45°

to about 60°

.

2. The connection interface of claim 1, wherein the receptacle and connector are configured to engage together in at least a first relative orientation and a second relative orientation.

3. The connection interface of claim 2, wherein, from the first relative orientation, the second relative orientation is achieved by rotating the connector about the longitudinal axis by approximately 180°

.

4. The connection interface of claim 1, wherein in the engaged state, the boss of the connector is received in the channel of the receptacle.

5. The connection interface of claim 1, wherein the connector further comprises a magnetic element configured to attract the receptacle.

6. The connection interface of claim 1, wherein the connector further comprises a gland configured to seal against the wall of the electrical device.

7. The connection interface of claim 6, wherein the gland is positioned on an outer peripheral wall of the connector.

8. The connection interface of claim 6, wherein the gland is configured to seal against a generally cylindrical surface.

9. The connection interface of claim 6, wherein the gland is configured to provide sealing around substantially an entirety of a periphery of the connection interface between the connector and the receptacle.

10. The connection interface of claim 1, wherein the first and second angled surfaces are at an angle, relative to the longitudinal axis, of approximately 60°

.

11. The connection interface of claim 1, wherein the receptacle comprises a first parallel surface that is substantially parallel to the longitudinal axis, wherein the receptacle comprises a second parallel surface that is substantially parallel to the longitudinal axis, and wherein the first and second parallel surfaces are configured to interact to inhibit lateral movement of the connector relative to the receptacle with the engagement of the connector to the receptacle.

12. The connection interface of claim 11, wherein the receptacle comprises a first perpendicular surface that is substantially perpendicular to the longitudinal axis, the first perpendicular surface connecting the first angled and parallel surfaces of the receptacle, wherein the receptacle comprises a second perpendicular surface that is substantially perpendicular to the longitudinal axis, the second perpendicular surface connecting the second angled and parallel surfaces of the connector, and wherein the first and second perpendicular surfaces are configured to be in contact with the engagement of the connector to the receptacle.

13. A receptacle configured to be positioned in a wall of an electrical device, the receptacle comprising:

a first set of electrical contacts; and

a channel comprising a first angled surface, the first angled surface being at an acute angle with respect to a coupling axis of the receptacle, wherein the channel surrounds the first set of electrical contacts;

the receptacle configured to removably engage with a connector along the coupling axis, the connector comprising a second set of electrical contacts and a boss having a second angled surface; and

the first angled surface of the receptacle being configured to interface with the second angled surface of the connector as the connector is moved into engagement with the receptacle, thereby guiding the connector into the receptacle such that the first and second sets of electrical contacts are in electrical communication with each other,
