An electrical connector includes: a conductive terminal including: a connector-side connecting part; a substrate-side connecting part; and an L-shaped bent part therebetween; a housing including: a terminal-holding hole holding the conductive terminal between the connector-side connecting part and the bent part; and an opening capable of exposing the substrate-side connecting part. The opening is used for connecting a circuit substrate. An alignment member is attached toward the substrate-side connecting part of the conductive terminal so as to close the opening. The alignment member is engaged with the housing in a state where the substrate-side connecting part projects from a through hole for inserting the conductive terminal therein. The engaging unit preventing the substrate-side connecting part of the conductive terminal from moving to the bent part, is provided between the conductive terminal and the through hole.

Electrical connector

A seal used for an electric connector having a part protruding outwardly through a first opening formed at a wall of a casing, the seal filling a space formed between an outer surface of the part and an inner surface of the first opening, includes a flat portion formed with a second opening having an inner edge entirely or partially identical in shape with an inner edge of the first opening, the flat portion lying on the wall such that the second opening overlaps the first opening, and a packing portion extending from the flat portion, and making close contact with both the outer surface of the part and the inner surface of the first opening.

Seal having a packing portion extending from a flat portion with a step

An electric connector includes a first housing including a guide shaft and a second housing including a guide hole into which the guide shaft is inserted. The guide shaft includes a main body, and a projection radially projecting from the main body, the guide hole being formed at an inner surface thereof with a groove into which the projection is fit. The projection and the groove are formed such that a first imaginary line intersects with a second imaginary line, the first imaginary line being defined by extending a contact plane at which the projection and the groove make contact with each other when the first housing rotates relative to the second housing, towards a center of the main body. The second imaginary line is defined as a line bisecting a top surface of the projection and extending towards a center of the main body.

Mating coaxial connectors having anti-rotational features

A casing in which an electric connector is housed, including a floor, and at least one wall standing perpendicularly to the floor, wherein the wall is formed with an opening, when a part of the electric connector projects outwardly through the opening, a seal formed around the part makes close contact with an inner edge of the opening, the casing further including a pair of guide paths allowing the electric connector at opposite ends thereof located in a first direction to slide towards the opening from inside of the casing on a first surface with which the electric connector makes contact at a lower surface thereof, the first direction being defined as a length-wise direction of the wall.

Casing having guide paths for an electrical connector

An electric connector includes a housing to be fit into a second electric connector, a lock arm resiliently deforming when the lock arm makes contact with an engagement part of the second electric connector, and thereafter, returning back to its original position, when the electric connector and the second electric connector are coupled to each other, a first detection terminal for detecting whether the electric connector and the second electric connector are electrically connected to each other, and a unit for assisting the lock arm to return back to the original position, the lock arm, the first detection terminal, and the unit being arranged in the housing, the detection terminal including a first portion to be fixed relative to the lock arm, and a second portion to make contact with a second detection terminal of the second electric connector.

Electric connector and detection terminal included therein

A casing in which an electric connector is housed, including a floor, and a wall standing perpendicular to the floor, the wall being formed with an opening, when a part of the electric connector projects outwardly through the opening, a seal formed around the part making close contact with an inner edge of the opening, the casing further including a first positioning unit for positioning the electric connector relative to the opening in a first direction defined as a length-wise direction of the wall, and a second positioning unit for positioning the electric connector relative to the opening in a height-wise direction of the wall.
