Abstract: A plug connector mounted on a board and that mates with a receptacle connector includes at least three signal contacts and two power contacts each including a contact portion that contacts the receptacle connector and a block that holds the signal contacts and the power contacts. The block includes a body and a fitting portion that protrudes away from the body and is inserted into a fitting port of the receptacle connector, and the signal contacts and the power contacts are disposed alternately in a row along an arrangement direction and symmetrically about a line that passes through a center position of the plug connector and is orthogonal to the arrangement direction when viewed from a fitting direction to the receptacle connector.

Abstract: A receptacle connector 20 includes a housing 200 in which a recess 203 for housing a plug connector 30 is formed on a side opposite to a surface mounted on a substrate of the housing, a required number of contacts 220 arranged between end portions of the housing 200, and reinforcement metal fittings 230 each of which is provided on one of the end portions of the housing 200. The reinforcement metal fitting 230 has a cantilever resilient piece 235 that extends in the arrangement direction of the contacts 220, and a contact piece 236 that extends from a free end portion of the cantilever resilient piece 235 and comes into contact with the plug connector 30 when the receptacle connector 20 and the plug connector 30 are fitted to each other.

Abstract: An electric connector includes a plug connector 30 and a receptacle connector 20. The receptacle connector 20 has a first housing 200 having first and second recess fitting parts 203a, 203b, and a required number of first contacts 220. The first and second recess fitting parts 203a, 203b have different shapes. The receptacle connector 20 has a first cover 240 that is made of metal and covers a part of a peripheral wall 202 of the first housing 200 that defines the first recess fitting part 203a, and a second cover 260 that is made of metal and covers a part of the peripheral wall 202 that defines the second recess fitting part 203b.

Abstract: An electrical connector that maintains connection stability and enables easy removal so as not to cause any damage during removal with a reduced size and reduced profile. At the time of removal of two connectors, when an operation portion of a locking member of the receptacle connector is pushed inward in the longitudinal pitch direction, a locking piece pushes and spreads an engagement portion of an engagement member outward widthwise, and simultaneously a protrusion portion is also moved outward widthwise, whereby the aforementioned lapped state is released and unlocked, enabling removal. When the operation portion is released, the locking piece is pushed inward widthwise by resiliency of the engagement portion, and the protrusion portion is returned to the initial position corresponding to the position in which the protrusion portion is lapped with a step portion when viewed from the fitting direction at the time of completion of fitting.

Abstract: The invention provides an electrical connector with a structure that maintains connection stability and enables easy removal so as not to cause any damage during removal while the size is reduced (particularly, in a widthwise pitch direction) and the profile is reduced. At the time of removal of two connectors 20 and 40, when an operation portion 601 of a locking member 60 of the receptacle connector 40 is pushed inward in the longitudinal pitch direction, a locking piece 602 of the locking member 60 pushes and spreads an engagement portion 502 of an engagement member 50 outward in the widthwise direction, and simultaneously a protrusion portion 501 is also moved outward in the widthwise direction, whereby the aforementioned lapped state is released and unlocked, enabling removal.
