Abstract

In an optoelectrical connector including two connectors to be interconnected, each having at least one optical connection part and at least two electrical connection parts, the electrical connection parts of one of the connectors are pins and the electrical connection parts of the other connector are spring contacts. The connector having the spring contacts includes, before the spring contacts, positioning holes in which the pins are to be inserted. The tips of the pins come into contact with the spring contacts to make electrical connection. The bases of the pins fit in the positioning holes to perform positioning for optical connection. The optoelectrical connector can be smaller, lighter, and thinner.
