Abstract

The present disclosure introduces methods and apparatus for connecting first and second downhole components. A first interface of a first subassembly is coupled to a first component. The first subassembly includes a first connector. A second interface of a second subassembly is coupled to a second component. The second subassembly includes a body and a second connector extendable from the body. The second connector remains communicably connected to the second interface by a conductor extendable from and retractable into the body, including when the second connector is extended away from the body and coupled to the first connector.

First claim

What is claimed is:

1. An apparatus, comprising:
a first interface and a first connector disposed at opposing ends of a first body, wherein the first interface is operable to detachably couple with a first downhole tool conveyable within a wellbore extending into a subterranean formation, and wherein a first conductor extends between the first interface and the first connector within the first body;
a second interface and a second connector disposed at opposing ends of a second body, wherein the second interface is operable to detachably couple with a second downhole tool, wherein a second conductor retractable into the second body extends between the second interface and the second connector, and wherein the second connector is operable to extend away from the second body and detachably couple with the first connector; and
a biasing member operable to urge the second connector towards a retracted position adjacent the second body.

2. The apparatus of claim 1 wherein at least a portion of the second conductor is armored.

3. The apparatus of claim 1 wherein the second conductor comprises a coiled portion having an extendable length.

4. The apparatus of claim 1 wherein the second connector detachably couples to the second body when retracted.

5. The apparatus of claim 4 wherein the detachable coupling of the second connector with the second body is magnetic.

6. The apparatus of claim 1 further comprising a spacer disposed between the first interface and the first connector.

7. The apparatus of claim 6 wherein the spacer sets a predetermined axial separation between the first interface and the first connector.

8. The apparatus of claim 7 wherein the spacer is one of a plurality of spacers collectively disposed between the first interface and the first connector.

9. An apparatus, comprising:
a first interface operable to mechanically and communicably couple with a first downhole electronic component;
a first connector communicably connected to the first interface;
a second interface extending from a body and operable to mechanically and communicably couple with a second downhole electronic component;
a second connector;
a conductor extending within the body and communicably connecting the second interface with the second connector, wherein the second connector is extendable away from the body to mechanically and communicably couple with the first connector, and wherein the conductor extends from and retracts into the body in response to relative axial movement of the second connector and the body; and
a biasing member urging the second connector towards a retracted position adjacent the body.

10. The apparatus of claim 9 wherein the conductor extends from and retracts towards the body in response to relative axial movement of the first and second downhole electronic components when the first and second connectors are coupled.

11. The apparatus of claim 9 further comprising the first and second downhole electronic components.

12. The apparatus of claim 9 wherein the body is a second body, the conductor is a second conductor, and the apparatus further comprises:
a first body extending between the first interface and the first connector; and
a first conductor extending within the first body and communicably connecting the first interface with the first connector.

13. The apparatus of claim 9 wherein the conductor comprises an axially extendable coiled portion.

14. The apparatus of claim 9 further comprising a downhole tool string conveyable within a wellbore extending into a subterranean formation, wherein the downhole tool string comprises a plurality of downhole electronic components, and wherein the plurality of downhole electronic components includes the first and second downhole electronic components.

15. An apparatus, comprising:
a first interface and a first connector disposed at opposing ends of a first body, wherein the first interface is operable to detachably couple with a first downhole tool conveyable within a wellbore extending into a subterranean formation, and wherein a first conductor extends between the first interface and the first connector within the first body;
a second interface and a second connector disposed at opposing ends of a second body, wherein the second interface is operable to detachably couple with a second downhole tool, wherein a second conductor retractable into the second body extends between the second interface and the second connector, and wherein the second connector is operable to extend away from the second body and detachably couple with the first connector; and
wherein the second connector detachably couples to the second body when retracted.

16. The apparatus of claim 15 wherein the detachable coupling of the second connector with the second body is magnetic.
