Endoscope electronics assembly
View Patent ↗A method for assembling an endoscope that includes an imaging subassembly inside an insertion tube having distal and proximal ends. The method includes coupling the imaging subassembly to a plurality of wires, which have respective first and second ends, by fixing the first ends of the wires to the imaging subassembly. A connector is coupled to the wires by fixing the second ends of the wires to the connector. After coupling the imaging subassembly and the connector to the wires, the imaging subassembly is installed in the insertion tube by passing the connector through the insertion tube from the distal end of the insertion tube to the proximal end. After passing the connector through the insertion tube, the connector is inserted in a receptacle.
1. A method for assembling an endoscope that includes an imaging subassembly inside an insertion tube having distal and proximal ends, the method comprising:
coupling the imaging subassembly to a plurality of wires, which have respective first and second ends, by fixing the first ends of the wires to the imaging subassembly;
coupling a connector to the wires by fixing the second ends of the wires to the connector;
after coupling the imaging subassembly and the connector to the wires, installing the imaging subassembly in the insertion tube by passing the connector through the insertion tube from the distal end of the insertion tube to the proximal end; and
after passing the connector through the insertion tube, inserting the connector in a receptacle.
2. The method according to claim 1 , and comprising testing the imaging subassembly by receiving signals from the connector after coupling the imaging subassembly and the connector to the wires and before installing the imaging subassembly in the insertion tube.
3. The method according to claim 1 , wherein inserting the connector in the receptacle comprises coupling the imaging subassembly to convey signals to a processing subassembly via the wires.
4. The method according to claim 1 , wherein the connector has an axis and comprises a first array of conductive elements disposed along the axis, and wherein coupling the connector to the wires comprises connecting the wires to the conductive elements.
5. The method according to claim 4 , wherein the receptacle comprises a second array of conductive pads, and wherein coupling the connector to the receptacle comprises aligning the first and second arrays, and exerting a pressure on at least one of the connector and the receptacle so as to engender an electrical contact between the conductive elements and the conductive pads.
6. The method according to claim 5 , wherein coupling the connector to the receptacle comprises inserting between the first and second arrays an elastomeric material comprising alternating conductive and non-conductive layers so that the electrical contact is formed through the elastomeric material.
7. The method according to claim 4 , wherein the connector comprises a dielectric substrate, and wherein the conductive elements are formed from a layer of conductive material that is disposed on the dielectric substrate.
8. The method according to claim 4 , wherein while passing the connector through the insertion tube, the axis of the connector is approximately parallel to the wires.
