An optical connector is constituted of a connector housing, a shielding case, and optical elements. The shielding case is split into a case main body section and a heatsink mechanism section, both joined together to constitute housing recesses. While the case main body section and the heatsink mechanism section are joined together, element main body sections are held between them. A non-joint plane of the heatsink mechanism section is housed in a case housing recess of the connector housing in an outwardly exposed state. A corrugated heatsink fin section is formed in the non-joint plane. The housing recesses into which the element main body sections are to be housed are partitioned from each other.

Holding structures for optical elements of an optical connector

Optical connector with a surface mounted shield

An optical connector according to this invention includes a connector housing having a casing receiving recess formed therein, a metal shield casing for receiving an element body portion of an optical element therein, and a metal shield cover for covering the connector housing. The metal shield casing is received and held in the casing receiving recess. The metal shield casing and the metal shield cover are thermally connected to each other being in mutual contact; the side surface of the metal shield casing is exposed to the exterior of the connector housing to be in surface-to-surface contact with the metal shield cover and therefore heat, generated by the optical element, is transferred to the metal shield cover from the metal shield casing and is easily radiated from the metal shield cover to the exterior. The metal shield casing and the metal shield cover may be formed integrally to constitute a shield member.

Optical connector with electromagnetic noise shielding and heat radiating properties

In an optical connector, element body portions of optical elements are fittingly received respectively in receiving recesses formed in a connector housing, and lead terminals of each optical element project outwardly from the receiving recess. The connector housing is made of a metal material, and ground contact surfaces for being held in surface-to-surface contact with a grounding circuit is formed on and projects from a lower surface of the connector housing beyond which the lead terminals project outwardly, and an insulating portion made of an insulating material is formed at a peripheral edge portion of an opening of each receiving recess over an entire periphery thereof.

Optical connector

An optical coupling connector portion, including ferrule portions, is provided at a widthwise central portion of a connector housing having a shape flattened in a direction of the width thereof. Female connection terminal portions, serving as electrical connection terminals, are provided in a distributed manner at widthwise opposite side portions of the connector housings disposed outwardly respectively of opposite sides of the optical coupling connector portion. An optical coupling connector portion, including ferrule receiving portions for respectively receiving the ferrule portions, is provided at a widthwise central portion of a second connector housing. Male connection terminal portions, serving as electrical connection terminal portions, are provided in a distributed manner at widthwise opposite side portions of the connector housing in corresponding relation to the female connection terminal portions.

Connector device and connector

In a state where an optical connector is mounted and fixed to a circuit board, a grounding piece formed on a shield case is pressed against a grounding wiring pattern formed on the circuit board by a fixing piece formed on a connector housing. A spring piece is formed by cutting and raising a part of the grounding piece into a strip-like shape while remaining another part to be uncut, and then bending the raised part into a substantially V-like shape. In the state where the optical connector is mounted and fixed to the circuit board, the spring piece is interposed between the fixing piece and the circuit board while being elastically deformed to be flattened.

Optical connector and shield case

In an optical connector device configured by a combination of an element-side optical connector which accommodates an optical element D, and a fiber-side optical connector which holds an optical fiber, an element accommodating housing member of the optical connector and a fiber holding housing member of the optical connector are formed by an electrically conductive resin. In a state where the optical connectors and are connected to each other, the fiber holding housing member is electrically connected to the element accommodating housing member

Optical connector device and optical connector

An optical connector is housed in a connector housing member while an optical element is housed in a shield case . The optical connector includes a connector housing member which is made of resin and has a case storage recess capable of housing the shield case , and a metal heatsink which is attached to the connector housing member so as to close a rear opening of the case storage recess . The heatsink section comes into contact with the shield case and is fitted into a rear opening of the case storage recess while being exposed to the outside.

Optical connector and shield connector therefor

In an optical connector, a shield casing having element body portions of optical elements received therein, is received in a connector housing member in such a manner that this shield casing can be contacted with a packaging surface of a packaging board Q.
