However, this fiber strand 115 is not supported at all near its tip. Therefore, in the plug 5, the optical fiber is held in a cantilevered state so that the fiber strand 115 near its tip can move somewhat.
- the tip of the optical fiber disposed there that is, the end surface 114 of the fiber filament 113, reaches near the middle of the alignment member 74, so Unlike the fiber strand 115 which can move, the fiber strand 113 of the jack can not float.
- the end faces 114 and 116 of the fiber strands 113 of the jack 3 and the fiber strands 115 of the plug 5 are butted and connected to each other in the alignment member 74. However, it is the same as the plug 5 in that when the jack 3 is assembled, it reaches the same position as the tip position of the end face 114 force of the fiber strand 113, the inner frame 61.
- These shielding members 83 and 85 are slidably attached to the protective members 73 and 75, respectively, in a direction intersecting with the longitudinal direction of the jack and the plug.

It is done. When no force is applied to the shielding members 83, 85, these shielding members 83, 85 are in the closed position as shown in a) of FIG.
- the fiber 11 is disposed at a position that substantially shields light emitted from the ends of the strands 113 and 115.
- these shielding members 83, 85 abut each other in the adapter 2 and collide with each other, they are slid against each other by the interaction of the panel panel 82 while the inclined surfaces 81 are in sliding contact with each other.
- the shielding member 83, 85 blocks light from an open position as shown in b) or c), that is, light emitted from the tip of the fiber wires 113, 115 from a closed position as shown in a) of FIG. Move to a position where As a result, the jack 3 and the plug 5 are optically connected.
- the plug 5 and the jack 3 will only be optically connected when they are abutted against each other and collided, preventing the light leakage effect on the eye can do.
- the shielding members 83 and 85 can prevent the inflow of dust, and can also reduce connection loss.
- the shielding member preferably has a substantially triangular cross-section that protrudes at least on the butt side in the longitudinal direction of the jack 3 and the plug 5.
- the inclined surfaces 81 should be complementary to each other as shown in FIG.
- the angle of inclination may be, for example, about 40 degrees.
- the shape of the shielding member is sufficient as long as it shields the light from the optical fiber 11, and the other portions have any shape.
- the thickness 80 (FIG. 7) of the shielding member may be thinner or not better than that shown, in other words, the shielding member may have a larger opening.
- the interaction between the plug shielding member 85 and the jack shielding member 83 will be described in more detail.
- the action of the force exerted by one on the other can be considered in two directions, ie, the longitudinal direction and the cross direction of this longitudinal direction.
- the latter force causes the jack and plug shields 83 and 85 to open as shown in b) and c) from the open position as shown in a) of FIG. Moved to position.
- the action by the former force is somewhat different between the jack and the plug.
- the protective member 73 to which the shielding member 83 is attached is provided in a state of slightly protruding from the inner frame 61 ', and can be moved relative to the inner frame 61' Since the former force does not, the shield member 83 of the jack is only pressed to the plug 5 side by this longitudinal force.
- the protective member 75 attached with the shielding member 85 is provided so as to be slid to the inside of the inner frame 61, so the shielding member 85 of the plug 5 The longitudinal force is inserted into the inside of the inner frame 61 of the plug together with a part of the protection member 73 while colliding with the shield member 83 of the jack.
- the plug protection member 75 moves inside the inner frame 61 of the plug.
- the inner frame 61 of the plug and the inner frame 61 'of the jack are the same, and therefore the same size, it is possible that the jack protection member 73 is inserted into the inner frame 61 of the plug. Only the part that protrudes from the jack's inner frame 61 '.
- the jacks 3 and the plugs 5 will be brought close to each other until their leading edges 62, 62 'of their inner frames 61, 61' collide. This state is shown in c) of FIG.
- the fiber strand 115 of the plug is provided on the protective member 73 of the jack. It is inserted into the alignment member 74. Since part of the fiber strand 113 of the jack is accommodated in advance in the alignment member 74, the end face of the fiber strand 115 is inserted by inserting the fiber strand 115 of the plug into the alignment member 74. The end faces of the fiber strands 113 are butted and butted and connected.
- an inclination is made such that it converges toward the fiber strand 113 of the jack 3 from the receiving side of the fiber strand 115 of the plug.
- a guide surface 76 may be provided.
- both shielding members can be accommodated inside one of the inner frames. Can be shared, and the device can be miniaturized.
- the longitudinal force causes the plug shielding member 85 to be inserted into the interior of the inner frame 61 or the protection member 75 to move inside the inner frame 61 in the cross direction. Only after it has been moved by the force from the closed position to the open position. Because, before the shield member 85 of the plug is moved from the closed position to the open position, a portion 86 of the back surface of the shield member 85 is the edge of the wedge inlet of the inner frame 61 in the cross direction with the longitudinal direction of the plug. It projects to the outside of the frame and collides with this edge 62 to serve as a stop for the inward movement of the inner frame 61. Thus, the shield member 85 prevents movement of the protection member 75 in its closed position and permits its movement in its open position.
- the protective member 75 is not slid inside the inner frame 61, so the optical fiber 115 is not accidentally damaged. Longitudinal direction for the same reason
- the force of the force causes the jack's shielding member 83 and part of the protection member 73 to be inserted into the plug's inner frame 61 only after the force in the cross direction has been moved from the closed position to the open position.
- the adapter 2 be attached to the board, panel or the like by soldering or the like before the jack 3 or the plug 5 is connected thereto.
- the adapter is not particularly provided with an alignment member for aligning the optical fiber, and according to such an attachment sequence, heat and vibration at the time of soldering to a substrate or the like can be obtained.
- the alignment member can not be misaligned due to an electric field, in other words, the effect of reducing the stress at the connecting portion of the fiber can be obtained.
- mounting is also easy.
- removal of jacks and plugs from the adapter is easy. Note that you may attach the jack or plug to this adapter first, or attach them at the same time.
- an optical connector using an adapter is illustrated, but the present invention is applicable to an optical connector not using an adapter.
