The portion 81 is a rectangular tubular cover portion 82 that is provided in front of the terminal holding portion 81 and that is fitted to the female housing 20.

The terminal holding portion 81 is formed with a plurality of through holes extending in the front-rear direction Terminal mounting hole 83 (see Fig. 6). The plurality of terminal mounting holes 83 correspond to the apertures 21 disposed in the lower side 2 of the apertures 21 of the female housing 20, and are formed on the lower side portion of the terminal holding portion 81. The terminal attachment holes 83 are arranged at a constant pitch in the width direction of the male case 80, and are arranged in two stages in the vertical direction.

Each of the terminal attachment holes 83 penetrates the center (axial center) of the columnar convex portion 84 which is individually provided in front of the terminal holding portion 81 (hereinafter referred to as a fitting surface 88). A guide portion 85 for guiding the front end of the male terminal metal member 70 is provided at the end portion of each of the terminal mounting holes 83. The male terminal metal fitting 70 is held toward the respective terminal mounting holes 83 from the rear.

In a state in which the rear portion of the holding portion 81 protrudes rearward, the male terminal metal member 70 is held by each of the terminal mounting holes 83. The connection portion 71 of the male terminal metal member 70 to the female terminal metal member 10 is arranged side by side in the width direction on the lower side portion of the fitting surface 88 and is divided into two stages in the vertical direction. Among the male terminal metal members 70, the portions projecting rearward from the rear of the terminal holding portion 81 are bent downward at a slight right angle and connected to the circuit board P, respectively. In the following, the portion of the male terminal metal member 70 that includes the connection portion 71 with the female terminal metal member 10 and extends in the front-rear direction is referred to as a horizontal portion 73, and a portion that is lowered toward the circuit board P is referred to as a hanging portion 74.

The length dimension of the lowermost portion of the male terminal metal member 70 (hereinafter referred to as the first male terminal metal member 70F) is longer than the length of the upper portion (hereinafter referred to as the second male terminal metal member 70S). smaller. That is, the length of the horizontal portion 73 of the first male terminal metal member 70F is made smaller than that of the second male terminal. The length of the horizontal portion 73 of the metal member 70S is smaller, and the connection position of the circuit board P is shifted forward and backward by the first male terminal metal member 70F and the second male terminal metal member 70S. Moreover, the length dimension of the hanging portion 74 of the first male terminal metal fitting 70F is made smaller than the length dimension of the hanging portion 74 of the second male terminal metal fitting 70S, and the first male terminal metal fitting 70F and the second male terminal metal fitting are made smaller. The 70S is disposed such that the connection portion 71 of the female terminal metal member 10 is shifted upward and downward.

Among the terminal holding portions 81, the uppermost portion corresponding to the idle hole 21V of the mother casing 20 is provided with an elongated pore portion 87 (see FIG. 6) in which the rear end portion is closed by the closing portion 86. The pore portion 87 has substantially the same shape as the portion of the terminal attachment hole 83 from which the guide portion 85 is removed.

The blocking portion 86 is formed in a portion corresponding to the guiding portion 85, and the guiding portion 85 has the same dimension as the front-rear direction. Further, the closing portion 86 and the terminal mounting hole 83 allow the mold to be a kit structure, whereby it can be selectively formed. That is, in each of the models, the position and number of the idle apertures 21V are different, and the setting method of the kit can be easily changed.

Next, the action and effect of the embodiment constructed as described above will be described.

The waterproof connector of this embodiment has a female housing 20 provided with a plurality of apertures 21 which are fixed to the end portion of the electric wire W and which can be inserted from the rear, and a part of the apertures 21 are not inserted into the female terminal metal member 10. And make it 21V for the idle aperture. In the mother casing 20, a through hole 41 penetrating in the front-rear direction at a position corresponding to the hole 21 is provided at a position on the rear side of the hole 21, and the circumferential surface of the through hole 41 can be densely combined on the outer circumference of the electric wire W. Liquid dense The waterproof rubber pin 40 is attached to the back side of the waterproof rubber pin 40 with the rear bracket 50 attached thereto. Further, a portion of the rear bracket 50 corresponding to the other aperture 21 of the non-idle aperture 21V is provided with a terminal introduction port 53 through which the female terminal metal member 10 can be guided forward, and a portion of the rear bracket 50 corresponding to the idle aperture 21V is provided. The closing portion 57 is closed, and a pressing seal portion 59 is provided on the front surface of the rear bracket 50, and the pressing seal portion 59 presses a portion surrounding the periphery of each of the through holes 41 in the rear surface of the waterproof rubber plug 40.

According to this configuration, the through hole 41 corresponding to the idle hole 21V among the waterproof rubber plugs 40 is blocked by the closing portion 57 of the rear bracket 50, and since the pressing portion 59 is pressed by the rear bracket 50 to seal the periphery, it is not necessary to The dummy aperture 21V is placed in the dummy plug, so that the increase in the manufacturing cost can be suppressed even if the number of the idle pores 21V is increased. Further, in addition to the uppermost aperture 21, if one of the other apertures 21 is to be an idle aperture 21V, the mold kit can be changed to form the closed portion 57, and only the components of the other apertures 21 can be prepared. bolt. Thereby, an increase in cost can be suppressed as compared with a case where all of the idle pores 21V require a dummy plug.

Further, the waterproof connector has a male housing 80 that is mounted on the circuit board P and that can be fitted to the female housing 20. The male housing 80 is provided with a plurality of male terminal metal members 70, and a male terminal metal member 70. The connection portion 71 with the female terminal metal member 10 is provided in two stages in the vertical direction on the fitting surface 88, and the portion on the opposite side to the connection portion 71 of the female terminal metal member 10 is respectively received from the terminal holding portion 81. The rear side is bent downward to be slightly bent at a right angle and connected to the circuit board P. Further, the plurality of apertures 21 provided in the female housing 20 are disposed corresponding to the male terminal metal member 70 and divided into a plurality of sections in the up and down direction. And The aperture 21 located at the uppermost portion among the plurality of apertures 21 is an idle aperture 21V, and the closed portion 57 is disposed corresponding to the uppermost idle aperture 21V.

According to this configuration, if the male terminal metal member having the longest dimension required for the male housing can be omitted, the male terminal metal member having the longest horizontal portion and the longest vertical portion at the uppermost portion of the male housing can be omitted. Efficiently reduce the cost of materials.

Further, the pressing seal portion 59 is provided with a rib 61 that surrounds each of the through holes 41 and is fitted into the rear surface of the waterproof rubber plug 40. According to this configuration, in the rear surface of the waterproof rubber stopper 40, the rib 61 is fitted and adhered to the periphery of each of the through holes 41, so that the liquid can be more reliably prevented from being inserted into the through hole 41 which is left unused.
