Abstract

The application is directed to various connector and sensor assemblies. In some embodiments, the connector and sensor assembly comprises a connector and a sensor assembly. The connector can have an opening that has a first surface and second surface that are opposite each other. The connector can have a plurality of retractable electrical connectors that extend from the first surface and a lock structure that is located on the second surface. The sensor assembly is comprised of a body portion and a proximal end. The proximal end has a top side and a bottom side. The top side includes a plurality of electrical contacts that is configured to interact with the plurality of retractable electrical connectors. The bottom side includes a key structure that is configured to interact with the lock structure in the connector.

Claims

1. An assembly comprising:

a connector comprising;

an opening with a first surface and a second surface, wherein the first surface and second surface are opposite each other, and wherein the second surface includes a proximal portion and distal portion that are connected by an angled ramp,

a plurality of retractable electrical connectors extending from the first surface, and

a lock structure located on the second surface; and

a sensor assembly comprising;

a body portion, and

a proximal end including a top side and a bottom side,

wherein the top side comprises a plurality of electrical contacts and the bottom side comprises a key structure configured to fit into the lock structure of the connector, and

wherein the proximal end is configured to be removably inserted into the opening of the connector.

2. The connector and sensor assembly of claim 1 wherein the plurality of retractable electrical connectors are pogo pins.

3. The connector and sensor assembly of claim 1 wherein the plurality retractable electrical connectors are in a staggered configuration.

4. The connector and sensor assembly of claim 1 wherein the plurality of electrical contacts on the sensor assembly are in a staggered configuration.

5. The connector and sensor assembly of claim 1 wherein the connector includes a first color indicator and the sensor assembly include a second color indicator, wherein the first color indicator and second color indicator are the same colors.

6. The connector and sensor assembly of claim 1 further including a first tapered surface on a proximal end of the connector and a second tapered surface on the proximal end of the sensor assembly, and wherein the first tapered surface tapers into the opening of the connector and the second tapered surface tapers outward.

7. The connector and sensor assembly of claim 6 wherein the tapered surface of the connector is configured to interact with the tapered surface of the sensory assembly.

8. The connector and sensor assembly of claim 7 wherein the tapered surface of the sensor assembly is configured to raise each of the plurality of retractable electrical connectors as the sensor assembly is inserted into the opening of the connector, wherein the tapered surface is configured to reduce the wear of the plurality of electrical contacts on the surface of the sensor assembly.

9. The connector and sensor assembly of claim 1 wherein the plurality of electrical contacts includes an electrical contact that serves as a grounding line.

10. The connector and sensor assembly of claim 9, wherein any of the plurality of retractable electrical connectors contacts the grounding line first before contacting any of the remaining plurality of electrical contacts.

11. The connector and sensor assembly of claim 1 wherein the lock structure includes a first detent and the key structure includes a second detent, wherein the first detent and second detent are configured to interact and provide a tactile feedback to the user.

12. The connector and sensor assembly of claim 1 wherein the lock structure is configured to only accept the key structure of the corresponding sensor assembly.

13. The connector and sensor assembly of claim 1 wherein the key structure is a plurality of indentations located on either side of the proximal end of the sensor assembly that can be secured by the lock structure of the connector.
