Waterproof connector

Claim 2

A waterproof connector, comprising: a rubber plug having a fixing portion for sealingly receiving and fixing a wire therein, a slidable portion slidable against said fixing portion in an axial direction of said rubber plug, an end terminal plug provided on said slidable portion and receiving the wire therein, and an expansion/contraction portion allowing for said slidable portion to slide in the axial direction of said rubber plug; a metal terminal stackingly fixing a core wire of the wire and said fixing portion, said metal terminal having a engaging hole; a connector housing having a lance engagable with said engaging hole of said metal terminal, and a terminal storage chamber having a rear opening for receiving said metal terminal, the rear opening of said terminal storage chamber being sealed by said end terminal plug; wherein said end terminal plug is formed in an umbrella shape with an outer peripheral surface that provides a tapered surface gradually reduced in diameter in a forward direction from a diameter greater than the diameter of said rear opening of said connector housing.

Claim 3

A waterproof connector according to claim 1, wherein said expansion/contraction portion of said rubber plug has a bellows shape and is arranged between said fixing portion and said slidable portion of said rubber plug.

Claim 4

A waterproof connector, comprising: a rubber plug stackingly fixable to a leading end portion of a wire to be inserted into a terminal storage chamber formed in a connector housing by a metal terminal engageable with a lance provided in the terminal storage chamber and stackingly fixable to the wire by the metal terminal, the rubber plug including an end terminal plug having a diameter greater than the diameter of a rear opening of the terminal storage chamber, wherein said rubber plug further includes an expansion and contraction portion capable of expanding and contracting in an axial direction of said rubber plug.

Claim 5

A waterproof connector, comprising: a rubber plug stackingly fixable to a leading end portion of a wire to be inserted into a terminal storage chamber formed in a connector housing by a metal terminal engageable with a lance provided in the terminal storage chamber and stackingly fixable to the wire by the metal terminal, the rubber plug including an end terminal plug having a diameter greater than the diameter of a rear opening of the terminal storage chamber, wherein said rubber plug further includes an expansion and contraction portion capable of expanding and contracting in an axial direction of said rubber plug.

Claim 6

A waterproof connector, comprising: a plurality of terminals, each terminal receiving a corresponding wire; a plurality of rubber plugs provided on a rear portion of each terminal, each rubber plug sealing the corresponding wire; a housing including, a plurality of terminal storage chambers, each terminal storage chamber storing a corresponding terminal, and housing side hold portions, each housing side hold portion projected in a rear opening of a corresponding terminal storage chamber, each housing side hold portion holding the corresponding wire in part; and a retainer removably mounted to a rear portion of said housing, said retainer including, wire insertion grooves, each groove cut in a direction perpendicular to a draw-out direction of each wire to be drawn out through a corresponding rubber plug from the corresponding terminal storage chamber and into which each wire can be inserted, and retainer side hold portions, each retainer side hold portion projected from the edge portion of the corresponding wire insertion groove, each retainer side hold portion holding the corresponding wire in part, wherein each housing side hold portion holds a part of an outer peripheral edge of the corresponding wire, and each retainer side hold portion holds a remainder of the outer peripheral edge.

Claim 7

A waterproof connector, comprising: a plurality of terminals, each terminal receiving a corresponding wire; a plurality of rubber plugs provided on a rear portion of each terminal, each rubber plug sealing the corresponding wire; a housing including, a plurality of terminal storage chambers, each terminal storage chamber storing a corresponding terminal, and housing side hold portions, each housing side hold portion projected in a rear opening of a corresponding terminal storage chamber, each housing side hold portion holding the corresponding wire in part; and a retainer removably mounted to a rear portion of said housing, said retainer including, wire insertion grooves, each groove cut in a direction perpendicular to a draw-out direction of each wire to be drawn out through a corresponding rubber plug from the corresponding terminal storage chamber and into which each wire can be inserted, and retainer side hold portions, each retainer side hold portion projected from the edge portion of the corresponding wire insertion groove, each retainer side hold portion holding the corresponding wire in part, wherein each housing side hold portion holds a part of an outer peripheral edge of the corresponding wire, and each retainer side hold portion holds a remainder of the outer peripheral edge.

Claim 8

A waterproof connector, comprising: a housing including a plurality of terminal storage chambers, each terminal storage chamber storing a terminal, and a retainer removably mounted to a rear portion of the housing and including wire insertion grooves which are cut formed in a direction perpendicular to a draw-out direction of a wire to be drawn out through a corresponding sealing rubber plug from each terminal storage chamber and into which the wire can be inserted, wherein retainer side hold portions for holding part of the outer peripheral edge of the wire are projectingly provided in an edge portion of each wire insertion groove and, housing side hold portions projectingly provided in a rear opening of each terminal storage chamber for holding the outer peripheral edge of the wire not held by said retainer side hold portions.

Claim 9

A waterproof connector, comprising: a housing including a plurality of terminal storage chambers, each terminal storage chamber storing a terminal, and a retainer removably mounted to a rear portion of the housing and including wire insertion grooves which are cut formed in a direction perpendicular to a draw-out direction of a wire to be drawn out through a corresponding sealing rubber plug from each terminal storage chamber and into which the wire can be inserted, wherein retainer side hold portions for holding part of the outer peripheral edge of the wire are projectingly provided in an edge portion of each wire insertion groove and, housing side hold portions projectingly provided in a rear opening of each terminal storage chamber for holding the outer peripheral edge of the wire not held by said retainer side hold portions.

Claim 10

A waterproof connector according to claim 4, wherein each rubber plug includes a fixing portion for sealingly receiving and fixing the corresponding wire therein, a slidable portion slidable against said fixing portion in an axial direction of said rubber plug, and an expansion/contraction portion allowing for said slidable portion to slide in the axial direction of said rubber plug, wherein each terminal stackingly fix a core wire of the corresponding wire and said fixing portion, each terminal having a engaging hole.

Claim 11

A waterproof connector according to claim 6, further comprising a connector housing including a plurality of lances, each lance engaging the engaging hole of each terminal.
