Description of the Related Art Conventionally, a general configuration known as a waterproof connector is such that a terminal fitting is fixed to the end of an electric wire, and a rubber plug having a plurality of folds on the outer periphery is arranged behind the terminal fitting and caulked and fixed by the terminal fitting. Like that. Then, as the terminal fitting is inserted into the terminal accommodating chamber of the housing, the folds of the rubber plugs are brought into close contact with the peripheral wall of the terminal accommodating chamber to seal between the electric wire and the peripheral wall.

のを提案した。In such a structure, if the rear end face of the rubber plug and the rear opening edge of the terminal accommodating chamber are not flush when the terminal fitting is mounted on the housing, a recess is formed. Although water accumulates and does not immediately flood, the vibration of the electric wire may cause a gap between the fold and the peripheral wall of the terminal accommodating chamber, and the accumulated water may be flooded. Therefore, the applicant of the present application, in the earlier application, at the rear end of the rubber stopper,
A terminal plug for closing the rear opening edge of the terminal receiving chamber is proposed.

傘状をなしている。This will be described with reference to FIGS. 4 and 5. The rubber stopper 31 has a substantially cylindrical shape, and has two flange-shaped folds 32 formed at the center in the axial direction, and a terminal accommodating chamber at the rear end. Is formed with a terminal plug 33 for closing the open end. The terminal plug 33 has an umbrella shape that expands outward and outward.

The exposed core wire 36 is fixed by caulking the wire barrel 38 of the terminal fitting 37, and the distal end of the coating of the rubber plug 31 and the electric wire 35 is fixed by caulking the insulation barrel 39. When the electric wire with the rubber plug 31 attached thereto is inserted into the terminal accommodating chamber 42 as described above, the lance 43 provided on the bottom surface of the terminal accommodating chamber 42 fits into the locking hole 44 formed in the terminal fitting 37. And locked. Thus, the fold 32 of the rubber stopper 31 is
When the terminal plug 33 closes the rear opening edge 42a of the terminal accommodating chamber 42 while being in close contact with the peripheral wall of the second housing 2, a reliable sealing function is exhibited.

構成部品の寸法誤差によることも考えられる。In such a structure, the terminal fitting 37 is locked, and the terminal plug 33 of the rubber plug 31 is closed.
In order to simultaneously fill the closing of the rear opening edge 42a of the terminal accommodating chamber 42, the locking hole 44 of the terminal fitting 37 and the terminal plug 33 of the rubber plug 31 are managed so as to be always at a constant interval. It is necessary to be. However, it is conventionally known that there is a variation in the dimensional management. The cause is that the terminal fittings first extend in the length direction when the wire barrel 38 is swaged. In this case, the distance between the locking hole 44 and the terminal plug 33 is increased. Another cause is that when the insulation barrel 39 is swaged, the rubber stopper 3 is set at the time of setting.
It is conceivable that there is a positional deviation from the normal position with respect to No. 1 or a dimensional error of each component.

う。When the distance between the locking hole 44 and the terminal plug 33 increases due to the above reasons, even if the terminal fitting 37 is inserted into the terminal accommodating chamber 42 and locked by the lance 43, the figure is not changed. As shown in FIG. 5, the terminal plug 33 of the rubber plug 31 does not reach the rear opening edge 42a of the terminal accommodating chamber 42, and the terminal plug 33 is brought into a non-contact state, thereby impairing the sealing function of the terminal plug 33.

を有する。As a means for achieving the above object, the present invention relates to a connector housing having a lance formed at a distal end of a wire inserted into a terminal receiving chamber. A terminal fitting to be locked is swaged and fixed, and a sealing rubber plug which is swaged and fixed by the terminal fitting is fitted to the electric wire, and the rubber stopper closes a rear opening edge of the terminal accommodating chamber. In a waterproof connector having a terminal plug formed therein, the rubber plug includes:
In order to adjust the distance between the position where the lance is locked in the terminal fitting and the position where the terminal plug comes into contact with the rear opening edge of the terminal accommodating chamber, an expandable / contractible portion that can expand and contract in the axial direction is formed. It has a feature in the configuration that is described.

係止が可能になる。The operation of the present invention is as follows. The distance between the locking position of the terminal fitting with the lance and the position of the terminal plug in contact with the rear opening edge of the terminal accommodating chamber is longer than normal because the rubber plug is fixed behind the normal position. When the terminal fitting is locked by the lance, the terminal plug may not be able to close the terminal fitting. At this time, by pushing the rubber stopper while contracting the elastic part provided in the rubber stopper,
The terminal plug can be closed by contacting the rear opening edge of the terminal receiving chamber. Conversely, if the distance between the locking position of the terminal fitting with the lance and the position of the terminal plug in contact with the rear opening edge of the terminal receiving chamber is shorter than normal, the terminal plug may be located at the rear opening edge of the terminal receiving chamber. There is a case where the lance cannot be locked to the terminal fitting in a state where the lance is in contact with the terminal. At this time, when the electric wire is held and pushed in, the terminal fitting is further pushed into the terminal accommodating chamber while the expansion and contraction portion of the rubber stopper is extended, so that the lance can be locked.

を向上させることができる。According to the present invention, the locking position of the lance in the terminal fitting and the abutment position of the terminal plug with the rear opening edge of the terminal accommodating chamber due to the mounting position of the rubber plug varying in the longitudinal direction. Even if there is an error in the distance between the rubber stopper and the expansion and contraction portion provided on the rubber stopper, it is possible to absorb the error while appropriately expanding and contracting, and the terminal stopper seals the rear opening edge of the terminal accommodating chamber, The locking of the terminal fitting by the lance can be reliably performed. In addition, the fact that the displacement of the mounting position of the rubber stopper is allowed means that the work of caulking the terminal fittings and the work of fitting the rubber stopper to the electric wire do not require high precision, so the work is simpler. As a result, work efficiency can be improved.
