Surgical instrument with recessed contacts and electrically insulating barriers

A surgical instrument, comprising:

• (a) a body assembly;
• (b) a shaft assembly, wherein the shaft assembly is configured to releasably attach to and extend distally from the body assembly;
• (c) an end effector at a distal end of the shaft assembly, wherein the end effector is operable to treat tissue;
• (d) a first electrical connector coupled to one of the body assembly or the shaft assembly, wherein the first electrical connector includes:
• (i) a connector body, and
• (ii) a first electrical contact supported by the connector body, wherein the first electrical contact is movable relative to the connector body between a first position and a second position;
• and
• (e) a second electrical connector coupled to the other of the body assembly or the shaft assembly, wherein the second electrical connector includes a second electrical contact,
• wherein the first electrical contact is configured to move from the first position to the second position to thereby electrically couple with the second electrical contact in response to attachment of the shaft assembly to the body assembly.

A surgical instrument, comprising:

• (a) a body assembly;
• (b) a shaft assembly, wherein the shaft assembly is configured to releasably attach to and extend distally along a longitudinal axis from the body assembly;
• (c) an end effector at a distal end of the shaft assembly, wherein the end effector is operable to treat tissue;
• (d) a first electrical connector coupled to one of the body assembly or the shaft assembly, wherein the first electrical connector includes:
• (i) a first connector body, and
• (ii) a first electrical contact recessed within the first connector body;
• and
• (e) a second electrical connector coupled to the other of the body assembly or the shaft assembly, wherein the second electrical connector includes:
• (i) a second connector body, and
• (ii) a second electrical contact supported by the second connector body,
• wherein the first connector body is configured to receive the second electrical contact therein to enable the first and second electrical contacts to electrically couple together when the shaft assembly is attached to the body assembly,
• wherein the second electrical contact is movable relative to the second connector body from a first position to a second position in response to attachment of the shaft assembly to the body assembly, wherein the second electrical contact is configured to electrically couple with the first electrical contact in the second position.
