Connector

摘要

A connector (F) includes a first terminal accommodating chamber (11), a rear end part of which defines a seal tower (12) projecting from a rear (10R) of a housing (10). A rubber plug (16) is fit on a first wire (15) and liquid-tightly contacts an inner surface of the first terminal accommodating chamber (11). Second wires (20) are drawn out from second terminal accommodating chambers (17). A one-piece rubber plug (30) covers the rear (10R) of the housing (10) and the second wires (20) and the seal tower (12) penetrate the one-piece rubber plug (30). Lock towers (21) project back from the rear (10R) of the housing (10) and penetrate the one-piece rubber plug (30). A rear holder (40) covers the one-piece rubber plug (30) from behind. Receiving portions (46) are formed in the rear holder (40) and lock to locking portions (23) of the lock towers (21).

主权项

1. A connector, comprising:
a housing; a first terminal accommodating chamber formed in the housing, a rear end part thereof serving as a tubular seal tower projecting backward from a rear surface of the housing; a first terminal fitting inserted in the first terminal accommodating chamber; a first wire connected to the first terminal fitting and drawn out backward from the housing; an individual rubber plug externally fitted on the first wire and to be liquid-tightly held in close contact with an inner peripheral surface of the first terminal accommodating chamber; a plurality of second terminal accommodating chambers formed in the housing; a plurality of second terminal fittings inserted in the plurality of second terminal accommodating chambers; a plurality of second wires connected to the plurality of second terminal fittings and drawn out to outside from the rear surface of the housing; a one-piece rubber plug mounted in the housing to cover an entire area of the rear surface of the housing; a plurality of seal holes formed in the one-piece rubber plug, the plurality of second wires liquid-tightly penetrating through the seal holes; a through hole formed in the one-piece rubber plug, the seal tower penetrating through the through hole; a lock tower projecting backward from the rear surface of the housing, penetrating through the one-piece rubber plug and formed with a locking portion on a projecting end part; a rear holder arranged to cover the one-piece rubber plug from behind; a receiving portion formed in the rear holder and configured to lock the rear holder in a state assembled with the housing by being locked to the locking portion; a seal formed on an outer periphery of the one-piece rubber plug and being liquid-tightly held in close contact with an inner periphery of a mating connector; and the rear holder being cantilevered forward and including a peripheral wall surrounding an outer peripheral surface of the housing and an outer peripheral surface of the one-peace rubber plug.
