A connector for high-speed transmission includes a housing, a column of contacts and a metal member in the contacts. The housing includes an opening portion to be fitted into an external communication partner. The contact has a contact portion in contact with the communication partner, a first linear portion extending rearward from a rear end of the contact portion, a second linear portion bent and extending from a rear end of the first linear portion and a terminal portion soldered to an external substrate. The metal member shorts the contact for ground and is bent so as to avoid contacts other than the contact for ground. The metal member has a bent portion bent in a U-shape across the contacts other than the contact for ground, and is connected to the first and/or the second linear portion of the contact for ground.

Connector for high-speed transmission

A connector set is provided that includes a first connector, a first cap to be attached to the first connector when the first connector is reflow-mounted on a first external substrate, a second connector, and a second cap to be attached to the second connector when the second connector is reflow-mounted on a second external substrate formed of a material with a smaller thermal expansion coefficient than that of the first external substrate. The second cap is formed of a material with a smaller thermal expansion coefficient than that of the first cap.

Connector set and cap

A connector set is disclosed that includes a plurality of connectors and a cap to be attached to the plurality of connectors when the plurality of connectors are reflow-mounted on an external substrate. Each one end portion of the connectors and the cap is provided with a fitted portion and a fitting portion to be fitted in the fitted portion. The fitted portion is provided with an opening portion for moving the fitting portion so as to absorb thermal expansion from one end portion side to the other end portion side due to temperature conversion of reflow.

Connector set and connector

A connector is provided that includes a plurality of socket type connectors to be mounted on a first substrate and a plurality of plug type connectors to be mounted on a second substrate, thereby electrically connecting the first substrate and the second substrate. The socket type connector includes a housing with a slot and a plurality of contacts arranged in the slot. The plug type connector includes a housing with a header to be fitted in the slot, and a plurality of contacts arranged in the header. The housing of the socket type connector and the housing of the plug type connector has a rotationally asymmetrical shape as viewed from a fitting direction.

Connector and connector set

According to an embodiment of the present disclosure, a connector for high-speed transmission to be fitted with an external counterpart connector includes a housing and a plurality of terminals. The housing has at least one or more slots. The plurality of terminals includes ground terminals and signal terminals are arranged in the slot along a first direction orthogonal to a fitting direction of the connector. Partition walls are provided between adjacent terminals in the slot, and a height of the partition walls between the ground terminals and the signal terminals in the fitting direction is lower than a height of other partition walls in the fitting direction.

A length of a protection wall, which is greater than a length of projection of a connecting end portion of a plug connector from opening end portions of an upper case as well as a lower case of an optical module, is set to be smaller than an interval between a contact surface of each of lower stopper pieces of a receptacle cage to come into contact with an end surface of a side wall as well as an end surface of an end surface of the lower case and an opening end surface of a slot of a host connector.

Transceiver module assembly having stopper positioning

When an optical module is inserted into a compartment of a receptacle cage in a state where a heatsink is detached from the receptacle cage, a tip end portion of a protection wall portion of the optical module comes into contact with end portions of guide pieces of a guide plate even if the optical module is inserted with the protection wall portion being lifted up, and the tip end portion of the protection wall portion is thereby pushed down and guided to a clearance below the guide pieces.

Receptacle assembly and transceiver module assembly

In a receptacle assembly, a module is guided by a guide rail and held inside an opening of a printed wiring board when a plug connector of the module is connected to a host connector. The receptacle assembly includes a guide member provided on the periphery of the opening of the wiring board and configured to form a module accommodation portion to detachably accommodate the module comprising a module board and to guide the module, a connector unit provided on the wiring board and configured to electrically connect the module board of the module to the wiring board, a first EMI gasket sealing a gap between a lower end portion of a connector cover covering the connector unit and the wiring board, and a second EMI gasket sealing a gap between a connecting end portion of the module and the periphery of an opening of the connector unit.
