Abstract: The electric connector includes a housing to be fit into a second electric connector, and a cylindrical hollow terminal making contact with a projecting terminal arranged in the second electric connector when the projecting terminal is inserted into the cylindrical hollow terminal, the housing and the cylindrical hollow terminal being formed integrally with each other by an insertion-molding process, the cylindrical hollow terminal being formed with a structure for preventing molten resin from flowing into an area at which the cylindrical hollow terminal and the projecting terminal make contact with each other while the inserting-molding process is being carried out.

Abstract: A housing used for an electric connector, includes a terminal space into which an electric terminal is to be inserted, and a lance for preventing the electric terminal from being slipped out of the terminal space. The lance includes a flexible portion, and a protrusion extending from the flexible portion and engaging with the electric terminal. The lance defines an escape space in which the flexible portion can be bent in a direction in which the protrusion and the electric terminal are disengaged with each other. The flexible portion has a passage along which a jig can move and which extends in a direction in which the jig is inserted into the lance, and the jig is used for disengaging the protrusion and the electric terminal from each other.

Abstract: An electric connector includes a male connector and a female connector, the male connector including a cylindrical main portion, and a male contact terminal formed at the main portion. The female connector includes a hole into which the main portion is fit, and a female contact terminal formed at the hole for making electrical contact with the male contact terminal when the main portion is fit into the hole. One of the male connector and the female connector includes a guide shaft axially extending in a direction in which the male connector is fit into the female connector, and the other of the male connector and the female connector includes a guide hole for allowing the guide shaft to be inserted thereinto to guide the guide shaft in the direction.

Abstract: An electric connector includes a housing having an opening and a bottom. The housing has a recess formed at the bottom and at least one electric terminal projects through a bottom of the recess into the housing. A sealant layer composed of cured light-curing resin at least partially fills the recess.

Abstract: An electric connector includes a housing having an opening and a bottom, the housing being formed at the bottom with a recess, a terminal inserted into the housing through a bottom of the recess such that a top thereof is located in the housing, and a cured resin filled in the recess, the recess having an inclining inner sidewall.

Abstract: The electric connector includes a plurality of terminals each having a stepped portion recessed or raised in a direction intersecting a direction in which the terminals are inserted into a later-mentioned housing, a housing formed with an opening, the terminals being inserted into the housing, and a holder inserted into the housing through the opening and engaged to the stepped portions of the terminals to thereby fix the terminals in the housing, the holder including a front and a pair of sidewalls all of which are shaped to be engageable to the stepped portions of the terminals when the holder is inserted into the housing, and a pair of flexible portions resiliently deformable to move towards and away from each other.
