Optical contact unit and optical plug
First Claim
1. An optical contact unit which constructs an elastic contact at which a ferrule A connected to the end part of an optical fiber is faced and mechanically couples on another ferrule B placed at the front side of the ferrule A, comprising:
- said ferrule A;
a ferrule holder which holds said ferrule A and the back end part to which said optical fiber of said ferrule A is connected;
an elastic member which gives said ferrule holder elasticity to translate in the optical axis direction of said optical fiber and holds said ferrule holder;
a tubular main body comprising at least said ferrule holder and said elastic member; and
a tubular cable adaptor which is inserted to the back opening part of said main body and is penetrated by said optical fiber, wherein said main body comprises a first small diameter part which has a first contact plane extending approximately vertical from the internal surface of said main body toward inside, said cable adaptor comprises a large diameter part which has a second contact plane extending approximately vertical from the external surface of said cable adaptor toward outside, a maximum radius of said large diameter part is larger than a minimum radius of said first small diameter part, said large diameter part is installed at the front side of said first small diameter part, and said second contact plane contacts to said first contact plane.

Abstract
A ferrule holder 110 and a coil spring 120 are comprised in a main body 130 formed in an approximately tube shape. A cable adaptor 140 comprising a front opening part 142 at a large diameter part 141 is inserted from a back opening part 133 into the main body 130 having slits S2 and S3. A first small diameter part 131 of the main body 130 fits with the large diameter part 141 of the cable adaptor 140 and prevents the cable adaptor 140 from translating in the z-axis direction. And the second small diameter part 132 of the main body 130 controls transfer of the ferrule holder 110 in the z-axis direction. At the forward part of the large diameter 141, a taper part which helps to insert the cable adaptor 140 is formed around the circuit of the optical axis. Each slit formed at the back opening part 133 also helps to insert the cable adaptor 140.
