A method of oblique spherical polishing of an optical connector by which a desired contact surface angle on an axis of the optical connector is obtained easily and securely without requiring additional processing. In order to form a dome of a radius R, which is oblique with the contact surface angle .theta.', at the end surface of the optical connector 20, which has ferrule 22 of which a tip 24 is beveled, the tip of the optical connector 20 is polished by tilting it with the angle .theta. which fulfills the relation

Optical connector and polishing method of its end surface

This invention offers a connector for base boards and a method for connecting base boards which is of low profile and produces highly reliable electrical connections due to the fact that it does not generate pressure applied perpendicularly to the base boards which may result in their warping. Connectors for base boards 10, 10' consist of the primary and secondary connectors 20a, 20b having L-shaped contacts 50 which are attached, preferably using the SMT method, to the lands 61, 62 formed on the matching surfaces of the base boards 60a, 60b. A longitudinal groove 41 is made in the primary connector housing 40a, and contacting sections 52, 52 of the contacts 50a of the primary connector 20a and contacts 50b of the secondary connector 20b, which is inserted in the groove 41, are connected by means of an elastic connecting component 30.
