The connector includes an inner housing, an outer housing, a locking mechanism for locking, a spring member that pushes back the inner housing during half fitting, and a pushback regulating position that regulates a pushback position. The pushback regulating portion includes a claw portion, a stepped portion against which the claw portion abuts, and a sliding load portion that makes a sliding friction force between the inner housing and the outer housing at a predetermined timing before abutting to be larger than the sliding friction force before the predetermined timing.

The present disclosure provides a card tray, a card tray plug-in device, and a terminal. The card tray may include a first supporting portion and a second supporting portion connected with the first supporting portion. The first and the second supporting portions may both be configured for placing data cards, and configured on a same side of the card tray along a thickness direction of the card tray. The card tray may include an electrical connection portion, a data card supported on the first supporting portion and/or another data card supported on the second supporting portion may electrically connect with a card holder of a terminal through the electrical connection portion.

In the connector, a female beak of a female housing includes a climbing surface formed on an end part at a removing direction side, and a tip end projection that protrudes in a removing direction from an end part at an upper direction side of the climbing surface. A male beak of a male housing includes a climbed surface formed on an end part at an inserting direction side, and that comes into contact with the climbing surface in a fitting direction. After connection of a male terminal housed in the male housing with a female terminal housed in the female housing is started, a tip end projection faces the male beak in a vertical direction. After the tip end projection faces the male beak, the climbing surface comes into contact with the climbed surface.

A connection module and a connector structure are provided. The connector structure includes a connection module and a joint module. The connection module includes a first joint unit, a connection unit having one end detachably connected to the first joint unit and the other end having fasteners, and a limit unit sleeved on the connection unit. The outer edge of each of the fasteners protrudes outward to form a top abutment portion. The joint module includes a second joint unit and a guide unit detachably connected to the second joint unit and having a joint portion. The guide unit is a hollow structure. The connection module is detachably connected to the joint portion through the connection unit to connect with the joint module. The fasteners are movably abutted against the joint portion through the top abutment portions. The limit unit is abutted against the joint portion.

A pluggable optical module may include a housing enclosing one or more optical components and one or more electrical components. The pluggable optical module may include a slider to move along an exterior wall of the housing in association with latching or unlatching the pluggable optical module. The pluggable optical module may include an electromagnetic interference (EMI) shield arranged in a gap between the slider and the exterior wall of the housing such that the EMI shield contacts the slider and the exterior wall of the housing. The EMI shield reduce EMI radiation passing through the gap.

An electrical connector includes a first member, a second member, and a sleeve connected to the first member. The sleeve may connect with a first component. The second member may connect with a second component. The first member may include a flange. The first portion of the sleeve may be disposed substantially at a first axial side of the flange. A second portion of the sleeve may be disposed substantially at a second axial side. The first and second members may include corresponding latching portions configured to selectively connect the first member with the second member and restrict relative axial movement between the first member and the second member. The latching portion of the second member may include a latching spring, and the latching portion of the first member may include a latching spring groove. When latched, the latching spring may be at least partially in the latching spring groove.

A holding frame for a plug-type connector is intended to have good heat resistance and a high level of mechanical robustness and, when installed in a metallic plug-type connector housing, enable protective grounding while at the same time being convenient to use, in particular during the replacement of individual modules. To this end, it is proposed to manufacture the holding frame at least partially from spring-elastic sheet metal. For this purpose, the holding frame can have a basic portion and a deformation portion, which are formed from different materials. The basic portion is used for fixing an accommodated module in a plane. The deformation portion can assume an insertion state and a holding state, wherein the insertion state permits insertion of at least one module into the holding frame in a direction transverse to the plane and an accommodated module is fixed in the holding state.

A female connector includes a female terminal and a female side insulation member. The female terminal includes a tubular-shaped female side connection body having a female side space portion therein into which the male side connection body is fitted in an inserting manner on a same cylinder axis. The female side insulation member includes a finger touch prevention body inserted into a first space portion of the outer tubular body and a male side space portion of the male side connection body. The finger touch prevention body is projected more than a tip end surface of the female side connection body. An insulating annular body projected more than the tip end surface of the female side connection body on a same cylinder axis is provided outside the female side space portion in a direction orthogonal to a cylinder axis direction of the female side connection body.
