Abstract: A plug includes a plurality of plug contacts arranged in a row and a plug housing. The plurality of plug contacts each include first bending portion and the like. The first bending portions and the like are aligned in a direction where the plurality of plug contacts are arranged. The receptacle includes second metal parts and a receptacle housing. When the plug and the receptacle are mated, the plurality of plug contacts of the plug are brought into contact with the plurality of respective second metal parts of the receptacle. When the plug contacts are brought into contact with the respective second metal parts, each of the second metal parts exerts a resistance force against pull-out of the plug from the receptacle. An auxiliary metal fitting exerts a resistance force with different magnitude from the magnitude of the receptacle contact.

Abstract: A plug connector 1 includes a plug-side housing 5 and plug-side power supply contact 5A which is held by the plug-side housing 5 and in which a power supply current flows, the plug-side power supply contact 5A comprises at least a pair of integrally formed spring contact portions 15A and 15B each having a bent-plate shape, and the pair of contact portions 15A and 15B are provided so that their flat surfaces face each other.

Abstract: A connector comprises a contact and a housing. The contact has a fixed portion, a contact portion, a spring portion and a held portion. The spring portion supports the contact portion. The held portion is located between the fixed portion and the support portion. The housing has a sidewall portion and a bottom portion. The sidewall portion is located outward of the spring portion in a predetermined direction and holds the held portion. The bottom portion is located under the spring portion in a vertical direction perpendicular to the predetermined direction. The housing has a gap between a lower surface of the spring portion and the bottom portion. The bottom portion and the sidewall portion hide the contact except the held portion both when the connector is seen from below along the vertical direction and when the connector is seen from the outside along the predetermined direction.

Abstract: A connector includes a plurality of contacts, a housing made of a predetermined material and a reinforcement member. The housing holds the contacts. The housing includes a bottom portion extending in a longitudinal direction of the connector. The reinforcement member is, at least in part, embedded in the bottom portion of the housing via insert-molding. The reinforcement member has a rib portion extending in the longitudinal direction. The rib portion has a reversed U- or V-shape cross-section and is filled with the predetermined material of the housing.

Abstract: A connector is mountable on a circuit board and mateable with a mating connector along a mating direction. The connector comprises a contact, a housing, an enclosing portion and a coupling portion. The housing holds the contact. The enclosing portion encloses an outer circumference of the housing in a plane perpendicular to the mating direction. The coupling portion directly or indirectly couples the enclosing portion with the housing so as to allow the enclosing portion to move along the mating direction relative to the housing.

Abstract: In a cooling device that includes a cooling roller that comprises a hollow tubular member and a cooling medium transport unit for transporting a cooling liquid to the inside of the cooling roller and contacts a sheet-like member to cool down the paper, a turbulence generating unit that generates turbulence in a cooling liquid is disposed near an inner wall of the outer tube.

Abstract: Provided is a connector having a locking mechanism that can ensure both the joining strength between a housing and a locking portion and the locking strength and that can cope with pitch narrowing and miniaturization. A plug connector comprises a plug-side housing, plug-side contacts provided to the plug-side housing and adapted to be electrically connected to a receptacle connector, and plug-side locking portions provided to the plug-side housing and adapted to maintain a connected state of the plug connector and the receptacle connector. The plug-side locking portions each comprise a locking plate having a flat plate-like shape and provided so that the normal direction of the plane of the flat plate is oriented in a locking direction with the receptacle connector, and retaining portions provided to the locking plate and formed so as to be integrated with the plug-side housing.

Abstract: Disclosed is a cooling device that includes a cooling part that is movably provided between a first position and a second position different from the first position with respect to an image forming apparatus main body and cools a periphery thereof with a cooling medium to be supplied; a cooling medium supply part that is provided in the image forming apparatus main body and cools and supplies the cooling medium to the cooling part; and a connecting member that connects the cooling part to the cooling medium supply part to circulate the cooling medium between the cooling part and the cooling medium supply part; wherein the connecting member is configured to include a flexible member and spirally provided with a moving direction of the cooling part as an axis center.

Abstract: A cooling device is disclosed. The cooling device includes a cooling section which is moveably provided with respect to an image forming device body between a first location and a second location, the second location being different from the first location, and which cools surroundings with a cooling medium to be supplied; a cooling medium supply section which is provided at the image forming device body and which cools the cooling medium to supply the cooled cooling medium to the cooling section; and a connecting member which connects the cooling section and the cooling medium supply section to circulate the cooling medium between the cooling section and the cooling medium supply section, wherein the connecting member includes a flexible member and is supported by a guiding member which guides an operation of tracking the connecting member in conjunction with movement of the cooling section.

Abstract: Provided is a technique of reducing a force required to couple a receptacle connector and a plug connector. A receptacle assistant fitting of the receptacle connector includes a cantilevered lock beam having a deflection part extending in a direction substantially parallel to a connector mounting surface of a receptacle side substrate and in the outside of a receptacle housing. A plug assistant fitting of the plug connector includes an engagement part that pushes aside the free end of the lock beam and rides over the free end of the lock beam so as to be engaged with the free end of the lock beam when the plug connector and the receptacle connector are coupled to each other.

Abstract: A cooling device includes a cooling roller having a dual tube structure including an inner tube disposed inside an outer tube, an outside flow passage and an inside flow passage in which a cooling medium flows, and an opening that allows the outside flow passage to communicate with the inside flow passage, a cooling medium transport unit, and a rotating tube joint unit mounted to one end side of the cooling roller. One end of the outer tube is coaxially rotatably fitted to a first fitting section of the rotating tube joint unit. One end of the inner tube is coaxially fitted into and rotatably or fixedly supported to a second fitting section of the rotating tube joint unit, and the other end is coaxially fitted into and rotatably or fixedly supported to a fitting section on the other end of the outer tube.
