A connector includes a housing and a connector position assurance device positioned in a temporary caught position on the housing when the connector is not mated with a mating connector. The connector position assurance device is allowed to slide to a caught position in front of the temporary caught position in a mating direction when the connector is completely mated with the mating connector. The connector position assurance device assures that the connectors are completely mated in the caught position. The connector position assurance device has a pressed-back portion abutted by the mating connector during mating and pressed back relative to the housing if the connector position assurance device is positioned in the caught position when the connector starts to mate with the mating connector, positioning the connector position assurance device in the temporary caught position at a complete mating of the connector with the mating connector.

A power-source connector includes a power-source terminal and a housing that supports the power-source terminal. The housing includes at least two adjoining insertion ports, each partitioned by a partitioning member and through any of which an electrically conductive member is inserted, and a housing space, connected to the insertion ports. The power-source terminal includes a contact portion, disposed in the housing space and being contactable with the electrically conductive member inserted through any of the at least two adjoining insertion ports. The contact portion is disposed so as to extend across the at least two adjoining insertion ports.

A railcar power connector includes a connector body defining a central opening configured to receive a portion of a cable, and a spring member having a protrusion moveable relative to the connector body between a locked position where the protrusion is configured to be secured to a mating connector and a released position where the protrusion is configured to be released from a corresponding recess of a mating connector. The protrusion moveable from the locked position to the released position upon a predetermined axial force applied to the spring member.

A plug connector has a housing, a locking spring, and a catch spring. The locking spring is connected to the housing and has a locking position and an open position. The catch spring is connected to the housing, and has a compressed position when the locking spring is in the open position and a rest position only when the locking spring is in the open position.

A small, low-profile plug connector for use with electronic devices provides a latching member with a pair of hooks that engage mating holes in a guide frame, and which can be easily disengaged from the guide frame or opposing connector or housing. The connector includes an elongated actuator interposed between the connector housing and latching member and the actuator terminates in a cylindrical cam member that is captured in a recess on the connector housing such that rearward movement of the actuator imparts a raising action to the latching member.

An auto-positioning structure for an upper cover of a network plug includes a base having an upper end and a rear end and an upper cover having an end pivoted to the upper end and assembled with the base to form a main body. A front portion of a network cable is inserted into the main body. A circuit board cooperates with a piercing terminal seat and a press plate to assemble with the network cable. A releasing spring sheet is disposed on the upper cover, and a front base is disposed on the base and corresponding to the releasing spring sheet. An unlock spring sheet is disposed on the front base and facing the releasing spring sheet, wherein the releasing spring sheet pushes the unlock spring sheet when the upper cover is lifted, and the upper cover is positioned when it reaches a predetermined angle.

A connector includes a first connector portion having a first contact point extending in a fitting direction and a second connector portion having a curved surface capable of inverting between a convex surface and a concave surface and a second contact point extending from the curved surface, the second contact point moving between a non-contacting position and a contacting position through inversion of the curved surface between the convex surface and the concave surface, the first connector portion being aligned with the second connector portion, with the second contact point being located at the non-contacting position, and the curved surface of the second connector portion being inverted so that the second contact point is switched to the contacting position, whereby the second contact point comes into contact with the first contact point to establish electrical connection between the first connector portion and the second connector portion.

A connector includes a first housing, a second housing and a fitting assuring member. The second housing includes a first locking protrusion portion having a first slope. The fitting assuring member includes a first assuring locking portion that gets over the first locking protrusion portion to be thereby locked to the first locking protrusion portion when the first housing and the second housing are fitted to each other. The first assuring locking portion begins to slide on the first slope before completion of the fitting, and stays on the first slope until the completion of the fitting.
