Abstract

PURPOSE:To obtain a coupling force having high reliability, and also, to prevent a clamper from falling off suddenly, by attaching a cover for covering at least a part of the rear end part of a housing, to the outside of the housing for pressing and fixing an optical fiber coupling member. CONSTITUTION:As for a housing 10, one end the vertical axis direction is opened, the upper face is provided with an elastic pressure piece 11 for pressing elastically an optical fiber coupling member 1, and to the outside of its rear end part 12, a cover 20 is attached. In the rear end face of the cover 20, a flat surface 21 on which a clamper 6 abuts at the time of coupling an optical connector is formed, and in its upper and lower parts, a step difference part 22 is formed. In such a way, the clamper 6 contacts at one point of this surface 21 and a clamp force works in the vertical direction to the surface 21, namely, in the direction parallel to the optical axis direction of the optical connector and an ideal coupling force is obtained, and since the step difference part 22 is formed, the clamper 6 is prevented from falling off suddenly.

10) The rear end (12) has a flat surface (2) on the outside.
By attaching the cover (20) formed with 1),
The clamper (6) contacts this point (2I) at one point and the surface (
21), that is, in a direction square to the optical axis direction of the optical connector, an ideal coupling force can be obtained. Furthermore, by forming protruding step portions (22) at both ends of the rear end flat surface (21),
Even if the clamper (6) in contact with the flat surface (21) shifts in the vertical direction, the stepped portion (22) limits the shift position of the clamper (6) and prevents the clamper (6) from accidentally moving. It is possible to prevent it from falling off.

In addition, in the optical connector of the present invention, the cover (20) is attached to the outside of the housing (10), so the height of the connector at the mounting section is approximately 1 mm.
) is higher than the height by the thickness of the cover (20). Therefore, as shown in FIG. 3, when the optical connectors are butted together inside the square sleeve (5),
Because the inner dimensions of the square sleeve (5) are smaller than the maximum height of the optical connector, the square sleeve (5) is a cover.
It is possible to abut the end and define the insertion amount of the optical connector into the square sleeve (5).

Furthermore, as shown in FIG.
), part of the bending force acting on the fixed plate (4) from the outside also acts on the housing (10), but in this case, the cover (20) is attached to the housing (10). As a result, the elastic pressing force of the cover (20) acts on the housing (10), and acts as a resistance force against the bending force acting on the optical fiber core fixing plate (4), The durability of the entire housing (10) against bending can be improved.
