供を目的とする。lO is an optical fiber. In the example shown in Fig. 2, a reference rk14t is formed on the adapter l, and positioning is performed by pushing out the reference rk14t in the direction of the arrow M with a lug 2t spring 5 against this reference Ji114. In the case of the example shown in Fig. 9.82, strict dimensional smoothness is required for the horizontal machining, which is disadvantageous in terms of cost. The object of the invention was made in view of the above-mentioned drawbacks of the prior art, and is to provide a simple structure that does not require high dimensional accuracy in machining, and that allows books to be joined to be accurately aligned and opposed to each other. The purpose is to provide an optical multi-connector adapter that can.

A plurality of original fibers 20 are buried in the plug 12 to be coupled with their end surfaces exposed. The adapter 11 into which the two plugs 12 are inserted has semi-cylindrical parallel surfaces 19 formed on both sides of the plug 12. Then, the next inner ring 17 that guides the reference surface 19 of the e-near 2 group \2 is formed on each 114 II circular surface. Such an adapter 11 may be integrally formed by bending a plate spring material as shown in FIG. Alternatively, as shown in FIG. 6, the plate spring 18 of the adapter 11 may be formed by integral molding or cutting of a metal material or plastic.
When the adapter 110 is not attached, it has a curved shape.

Therefore, both plugs can be precisely aligned and aligned along the seven guide surfaces with a simple structure and without requiring high precision in machining. In addition, as shown in Figure @8, leaf springs can be installed above and below 5. When installing and removing the plug, press the leaf spring from above and below to widen the gap between both guide grooves
It is possible to eliminate frictional resistance.
