Abstract: A host connector includes a connector insulator having a slot allowing detachable insertion of a plug connector of a module, a first contact terminal group including contact terminals arranged inside the connector insulator and each brought into contact with a contact pad on one side at a connection end of the plug connector, and a second contact terminal group including contact terminals each brought into contact with a contact pad on another side opposed to the aforementioned contact pad. The first contact terminal group includes grounding sub-contact terminals arranged inside slits of the connector insulator, grounding main contact terminals supporting the grounding sub-contact terminals, and signal contact terminals. Contact portions of each grounding main contact terminal and of each signal contact terminal having the same shape are arranged on a common straight line, and the signal contact terminals are disposed between the grounding main contact terminals.

Abstract: 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.

Abstract: 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.

Abstract: A liquid level indicating device includes a moving member which is arranged in a liquid tank storing a cooling liquid and moves vertically in conjunction with variation in a liquid level of the cooling liquid, a string member having one end portion connected to the moving member, the string member being configured to be bendable and non-extendable in a longitudinal direction, an indicator connected to the other end portion of the string member and which indicates a height position of the moving member as a remaining amount of the cooling liquid by operating in conjunction with movement of the moving member through the string member, and a tube member which is configured to be bendable and non-extendable in the longitudinal direction, has the string member passed therethrough, and connects the liquid tank and the indicator.

Abstract: 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.

Abstract: In a transceiver module, where one end of a module substrate is inserted and connected to a concave portion of a plug connector and when one end face of the module substrate is touched to the inner periphery face forming the concave portion, a projection portion formed at the periphery of the concave portion of the plug connector is fitted to a notch portion of the module substrate.

Abstract: A cable connector includes a connection end portion of a flexible board, in which a rectangular reinforcing plate molded of a conductive resin material is fixed to part of an upper surface of a ground plate. The connection end portion of the flexible board is electrically connected to a printed circuit board through the cable connector.

Abstract: An electrode portion of a module board to be disposed in a transceiver module is formed from a group of contact pads which are arrayed substantially in parallel to a long side of the module board, and the group of contact pads include a line of ground line pads formed at predetermined intervals from one end to the other end, and two lines of signal line pads formed in spaces between the ground line pads.

Abstract: A contact unit includes signal and power-supply contact terminals, a first blade in which the contact terminals are nipped and held, and a second blade. In each contact terminal formed of a conductive metal material by using the MEMS technique, for example, a tapered portion of a short-circuit piece and a tapered portion of another short-circuit piece come into contact with each other when a pressure at a predetermined value or higher is applied to a first contact and a second contact in a direction to come close to each other.
