An optical element 30 is inserted into a cover 40, and then the cover 40 is mounted onto a housing 10. At this moment, the upper ends of lateral contacts 20a and 20c, which are provided in the housing, enter lateral clearance slots 52a, which are provided in the cover, while the upper end of a central contact 20b enters a central clearance slot 53a. At the same time, the lateral leads 33a and 33c of the optical element are pressed down by a front bottom 52 of a groove, which is provided in the cover, into the slits 22 of the contacts 20a and 20c while the central lead 33b of the optical element is pressed down by a rear bottom 53 of the groove into the slit 22 of the contact 20b. In this construction of an optical connector, the leads are not bent, so they can be made relatively short. In this way, the axial length of the optical connector can be made relatively short to realize a miniaturization. |

DETAILED DESCRIPTION It is an object of the present invention to provide an optical connector which does not require any bending of the leads of an optical element.
Another object of the present invention is to provide an optical connector which has a relatively short axial length.
Another object of the present invention is to provide an optical connector which is relatively small and compact as a whole.
An optical connector according to the present invention comprises an optical element, a housing which includes a contact, and a cover.
The optical element, which is formed in a cylindrical figure, includes a light-capturing/emitting surface on one face thereof and an axially extending element lead on the other face in its axial direction.
The housing includes a base portion and an optical fiber receptacle.
The base portion further includes an element receptor portion, which is formed opening upward and rearward on an upper side of the base portion, to accommodate and retain the optical element.
The optical fiber receptacle, which is formed in front of the element receptor portion, is to accept and retain a ferrule that is attached to an end of an optical fiber.
The contact, which is provided in the housing, passes vertically through the base portion in rear of the element receptor portion, and the contact includes at the upper end thereof a lead connector portion, with which the element lead of the optical element is brought into contact, and at the lower end thereof a contact lead portion, which is used for connection to a circuit board, etc.
The cover includes an element holder portion to accommodate and retain the optical element, and it is mountable on the housing, covering the base portion.
Preferably, the lead connector portion is formed in a "U" figure with a slit, into which the element lead is press-fit.
When the optical element, while being oriented such that the light-capturing/emitting surface faces the optical fiber receptacle and the lead extends straight rearward, is mounted into the element receptor portion, the element lead is brought into contact with the lead connector portion of the contact
