However, in the above-mentioned waterproof connector 31, the electric wire has a sealing property of the through hole 3.
Since it is performed by the ring-shaped projecting portion provided in 9, it is necessary to lengthen the through hole 39 to increase the number of projecting portions in order to further improve the sealing performance. However, in the configuration in which the through hole 39 is elongated, the housing 32 of the waterproof connector 31 is
Has the problem of becoming large. Further, since the ring-shaped projecting portion has a cylindrical shape, there is a problem that when a flat wire other than the round wire is used, a gap is created, which lacks versatility. Furthermore, in order to improve the sealing property, it is necessary to reduce the diameter of the ring-shaped protruding portion,
When the diameter is small, there is a problem that the insertability of the electric wire deteriorates, workability at the time of assembling decreases, and the diameter of the electric wire to be used is limited.

Next, as shown in FIG. 4, in the step of press-fitting the seal member 4 into the housing 2, the surface of the seal member 4 is press-fitted from the open end of the housing 2. Since the seal member 4 is made of an elastic member, the upper and lower ends of the housing 2 in the figure can be elastically deformed. next,
The pressing plate 21 of the protective plate 5 is inserted into the insertion groove 18, and the seal member 4 and the protective plate 5 are fitted together. Here, the seal member 4
A tilt angle θ is formed between a line connecting the center portion P in the vertical direction in the figure and the end surface of the housing 2 and the inner side surface of the unfolded protective plate 5.

Next, as shown in FIG. 5, the upper and lower end portions of the protective plate 5 are bent so as to cover the outside of the housing 2, and then the locking projections 25 are fitted into the locking grooves 11 to end the protective plate 5. Is locked to the locking claw 12. Therefore, the protection plate 5 is bent along the taper surface of the rear end surface of the housing 2 having the inclination angle θ, and is not separated from the housing 2 unless the end of the protection plate 5 is removed from the locking claw 12. .
Therefore, if it becomes necessary to remove it for maintenance, it can be easily removed.

That is, since the protective plate 5 is in contact with the seal member 4, when the upper and lower end portions are locked to the housing 2, the protective plate 5 is deformed into a gentle arc by the action of the deformation groove 23. Then, the upper and lower ends of the protective plate 5 are pressed against the rear end surface of the housing 2 to the extent that the locking projection 25 can be locked in the locking groove 11, and are bent in the hinge groove 24. Therefore, the protective plate 5 is bent in a substantially U-shape in the vertical direction in the figure in a state of being in close contact with the rear end surface of the housing 2 around the position P.

What should be noted here is that the pressing plates 21a and 21c at the upper and lower ends in the figure incline inward in response to the bending of the protective plate 5. That is, the pressing plate 21b corresponding to the position P remains horizontal, but the upper and lower end portions of the protective plate 5 are largely bent, so that the pressing plates 21a and 21c at the upper and lower ends are inclined in correspondence with the bending. Become. Then, the upper pressing member 19a is strongly pressed against the electric wire 3a by the inclination of the upper pressing plate 21a, and elastically presses against the surface of the electric wire 3a by the interaction with the middle pressing member 19b.
Therefore, the sealing property of the electric wire 3a is improved and the infiltration of water or the like can be surely prevented.

Needless to say, the waterproof connector of the present invention is not limited to the above-mentioned embodiment, and, for example, in a waterproof connector 1A having a one-pole vertical electric wire pole as shown in FIG. It is feasible. That is, after bending the upper and lower ends of the protection plate 5A so as to cover the outside of the housing 2A, the locking projections 25 are fitted into the locking grooves, and the ends of the protection plate 5A are locked by the locking claws 12. Therefore, when the protective plate 5A is bent along the rear end surface of the housing 2A by providing a taper surface on at least one rear end surface (upper side in the drawing) of the housing 2A as shown in the drawing, the upper pressing plate 21a is Incline inward. Due to the inclination of the pressing plate 21a, the upper pressing member 19a is strongly pressed against the electric wire 3, and the surface of the electric wire 3 is elastically pressed by the interaction with the lower pressing member 19b. Therefore,
Similar to the above-described embodiment, the sealing property of the electric wire 3 is improved and the infiltration of water or the like can be surely prevented.

As described above, the waterproof connector according to the present invention accommodates the connection terminal connected to the end of the electric wire,
A housing provided with a taper surface inclined from the central portion of the rear end surface on the wire pull-out side toward the end direction, a seal member provided with a pressing member for pressing the electric wire, and a state in which the seal member is press-fitted into the housing. And a protection plate provided with a plurality of pressing plates that are inserted into the insertion groove formed in the pressing member and that tilt the pressing member to press the electric wire.

Therefore, since the seal member is configured to be pressed against the electric wire side in accordance with the deformation of the protective plate to improve the electric wire sealability, the electric sealability can be improved regardless of the outer diameter and shape of the electric wire. This improves the versatility of the waterproof connector. Further, since the pressing member is pressed against the electric wire after the electric wire is wired and the protective plate is inserted into the seal member,
At the time of wiring, the wiring work of the electric wire is easy, and both the assembling work of the waterproof connector and the wiring work of the electric wire are facilitated, and the working efficiency can be remarkably improved.
