Provided is a connector unit which can prevent damage to respective parts during rotation of a lever member. A fitting portion of a female outer housing fits with a to-be-fitted portion of a male outer housing, wherein timing of the fitting is after timing of insertion of a guide projection into a guide groove and timing of releasing of a restriction arm by a release projection. Fitting of the fitting portion with the to-be-fitted portion allows an operator to feel a change in force required for operation during moving the male outer housing and the female outer housing toward each other. By rotating the lever member after the operator felt the change in the force, damage to the guide projection and the restriction arm and such can be prevented.

An electrical connector includes a connector housing configured to receive a corresponding mating connector, a cable guide cover attached to the connector housing, and a mate assist system for assisting in mating to the corresponding mating connector. The mate assist system includes a lever moveable to assembly, open, and closed positions. The lever includes gear means connected with a slider in the connector housing. The lever moves the slider to a first, second, and third position. The lever is releasable and attachable to the connector housing only in the assembly position. The cable guide cover is attachable to the connector housing only when the lever is in the closed position. The slider has a releasing means cooperating with a releasing means of the corresponding mating connector to unblock the slider while mating and enabling movement of the lever to the closed position, thereby moving the slider to the third position.

A connector includes a first housing, a second housing, a mate assist slider, and a cam gear. The first-housing has a first outer surface. The second housing is configured to mate with the first housing, and the second housing includes a pin extending from a second outer surface. The connector also includes a mate assist slider moveable from an unmated position to a mated position. The connector also includes a cam gear mounted to the first outer surface. The cam gear moves in response to a movement of the mate-assist-slider from the unmated position to the mated position. The cam gear has a cam slot with an inertial detent. A vibratory feedback is provided to an assembler indicative of a properly positioned connector housing when the pin is moved past the inertial detent.

A lever-type connector has a male housing (10) including a bottom wall (11) formed with through hole (23, 24) and a receptacle (12) extending forward from an outer periphery of the bottom wall (11). A female housing (30) is capable of fitting into the receptacle (12). A lever (33) is mounted on the female housing (30) and connects the male and female housings (10, 30) by being rotated from an initial position to a connection position. An arm (36) of the lever (33) is between an outer surface of the female housing (30) and an inner surface of the receptacle (12). First and second closing portions (40, 41) are on the arm (36) and are configured to close a clearance between an upper opening (13) of the receptacle (12) and the lever (33) by being above the through holes (23, 24) with the lever (33) at the connection position.

A plug connector comprises a first plug, a second plug, and a securing device configured to mechanically secure the first plug to the second plug. The second plug has a receptacle with a ramp surface and a locking surface. The securing device has a lever pivotably mounted on the first plug. The lever pivotably bears a connecting element which has a securing cam on a free end of the connecting element. The receptacle of the second plug receives the securing cam and the ramp surface of the receptacle cooperates with the free end of the connecting element to forcibly guide the securing cam behind the locking surface of the receptacle when the first plug and the second plug are plugged together.

A circuit board is adapted for inserting an expansion card with an electrical contact part, a non-electrical convex part, and a positioning part. The circuit board includes a board body, a slot, a release structure, and a transmission mechanism. The slot is disposed on the board body and includes a socket, a connecting end, and an outer surface. The socket is adapted for the electrical contact part to be inserted. The release structure is movably disposed at the connecting end and includes a limiting part. The transmission mechanism is disposed in the socket, adjacent to the connecting end, or adjacent to the outer surface. The transmission mechanism includes a driving member and a linking member. The driving member is adapted for contacting the electrical contact part, the non-electrical convex part, or the positioning part. The linking member is disposed between the driving member and the release structure.

A wire cover (30) can be mounted to a connector body (C) in any one of a first direction and a second direction opposite to the first direction with respect to a wire drawing port (31). A first mark (M1) and a second mark (M2) having different appearance from each other are provided in the wire cover (30). A first identification mark (S1) is provided on one of both side surfaces of the connector body (C) and a second identification mark (S2) is provided on the other side surface. When the wire cover (30) is mounted in the first direction, the first mark (M1) and the first identification mark (S1) are disposed close to each other. When the wire cover (30) is mounted in the second direction, the second mark (M2) and the second identification mark (S2) are close to each other.

A connector includes a first housing, a second housing, a mate assist slider, and a cam gear. The first-housing has a first outer surface. The second housing is configured to mate with the first housing, and the second housing includes a pin extending from a second outer surface. The connector also includes a mate assist slider moveable from an unmated position to a mated position. The connector also includes a cam gear mounted to the first outer surface. The cam gear moves in response to a movement of the mate-assist-slider from the unmated position to the mated position. The cam gear has a cam slot with an inertial detent. A vibratory feedback is provided to an assembler indicative of a properly positioned connector housing when the pin is moved past the inertial detent.

A connector 10 includes a connector body 20, a lever 90 rotatably supported on the connector body 20 and configured to properly connect the connector body 20 and a mating connector body 120 at a connection position, a detector portion 60 separate from the connector body 20 and to be fit to a mating detector portion 160 when the lever 90 is at the connection position, and a detection-side sealing portion 80 to be liquid-tightly arranged between the detector portion 60 and the mating detector portion 160. The detector portion 60 and the lever 90 include movement converting portions for converting a rotational movement of the lever 90 into a linear movement of the detector portion 60 with respect to the mating detector portion 120 by contacting each other.
