Abstract
A contact pin subassembly including a plurality of contact pins, a contact pin holder which holds the contact pins and which is provided with a plurality of insulation ring portions in which the associated contact pins are slidably fitted, and springs which are held in the contact pin holder to bias the contact pins outward from the insulation ring portions. The contact pins subassembly may be combined into an assembly with a camera body, a lens, or some other subassembly of a device or instrument which requires contact pins, by mounting to the respective subassembly.
Claims18
A contact pin subassembly comprising:
- a plurality of contact pins;
- a self contained, insulative contact pin holder which holds said contact pins and which is provided with a plurality of insulation ring portions within which the associated contact pins are slidably fitted;
- springs which are held in said contact pin holder to bias said contact pins outwardly from said insulation ring portions;
- and,
- an electrical circuit board provided on the contact pin holder to electrically connect the contact pins through the springs;
- wherein said subassembly is capable of being independently assembled, the springs are inserted between the contact pins held by the contact pin holder, and the circuit board to bias the contact pins against the circuit board, the contact pin holder includes a shaft portion projecting toward the circuit board and the circuit board has an insertion hold which has a diameter larger than the shaft portion, so that the shaft portion can be loosely fitted in the insertion hole, and the shaft portion is provided with a threaded hole in which a set screw is screwed through the insertion hole.
