た構造である。2. Description of the Related Art FIG. 4 shows a conventional rubber plug mounting type terminal fitting 21. This terminal fitting 21 is of a type that has an electric contact portion 23 on the front side of a substrate 22, and a rubber plug 25 and an electric wire 26 are caulked simultaneously on a rear wire connecting portion 24. Several different size electric wires 26

Since the standard of the bottom wall Gb of the insulator crimping piece 24b is fixed and the electric wires 26 1 , 26 2 , 26 3 of different sizes are used, the crimping height of each crimping piece 24a, 24b varies depending on the size. For example, if the standard electric wire for the terminal fitting 21 is the electric wire 26 2 , and 1/2 of the crimp height is h, the small electric wire 26 1 has a low value of h 1 and the large electric wire 26 1.
At 3 , it becomes as high as h 3 . As a result, the center line (axis) of the terminal fitting 21 and the center of the rubber plug 25 do not coincide.

Therefore, the center of the rubber stopper 25 is displaced. Therefore, the pressing force on the upper surface and the lower surface of the inner wall of the housing portion of the rubber plug 25 becomes uneven, and the electric wire 26
A uniform sealing property cannot be obtained against the runout.

る。In order to achieve the above-mentioned object, according to the present invention, as described in claim 1, one of the substrates is connected with an electric contact portion for a mating terminal fitting, and the other of the substrates is connected. In a waterproof connector terminal fitting in which an electric wire connecting portion for an electric wire externally inserted with a rubber plug having a large-diameter sealing portion and a small-diameter terminal connecting tubular portion is formed, the electric wire connecting portion stands up from the substrate in a wing shape. A structure including a pair of conductor crimping pieces connected to each other and a pair of sandwiching pieces for standing up and standing from the substrate through a punched portion to the terminal connecting tube portion is adopted. As described in claims 2 and 3, the pair of sandwiching pieces are erected from the substrate so as to face each other or stagger each other.

れでもよい。According to the first aspect of the present invention, the connection structure between the terminal fitting and the rubber plug has a pair of pinching pieces, that is, a pair not having a fixed wall, in which a small-diameter terminal connecting tube portion of the rubber plug is formed through a punched portion. It is fixed by sandwiching it from the side with the sandwiching piece. Therefore, the center of the rubber stopper can be aligned with the axis of the terminal fitting by adjusting the holding position of the rubber stopper according to the size of the electric wire. As a result, when the terminal fitting with the rubber plug is inserted into the terminal accommodating chamber, the sealing portion of the rubber plug uniformly elastically contacts the entire inner wall of the rubber plug accommodating portion, so that uniform sealing performance can be obtained. If the pair of holding pieces are not directly connected to each other through the punching portion of the substrate, the pair of holding pieces may be in contact with each other.
As described above, the structure may be opposed to each other or the structure may be staggered.
