  The waterproof connector C is provided with a seal plate 50 that seals between the housings 10 and 30 when fitted. The seal plate 50 is formed separately from the male housing 10 and the female housing 30, and is mounted and held in advance on the male facing surface 16 of the male housing 10 before the two housings 10 and 30 are fitted together. ing.

  The seal plate 50 is formed of a synthetic resin material (for example, polypropylene or polybutylene terephthalate) that is harder than rubber. Although the seal plate 50 is harder than rubber, the seal plate 50 has enough elasticity to contact the housings 10 and 30 and seal between them.

  The seal plate 50 includes a seal main body 51 having a substantially square plate shape along the male facing surface 16 and a pair of seal walls 52 and 53 protruding from the seal main body 51 in the fitting direction of the housings 10 and 30. I have. Of the pair of seal walls 52, 53, the seal wall protruding toward the male housing 10 is referred to as a male side seal wall 52, and the seal wall protruding toward the female housing 30 is referred to as a female side seal wall 53.

  The seal body 51 is a plate having a size that covers almost the entire surface of the male facing surface 16 (the rear end surface of the hood portion 12) of the male housing 10. A pair of circular through holes 54 are formed side by side at the center of the seal body 51. The tab 22 of the male terminal 20 can pass through the through hole 54 and protrude forward of the seal body 51. The male side seal wall 52 has a cylindrical shape protruding from the hole edge of the through hole 54 to the rear side in the fitting direction, and the female side seal wall 53 protrudes from the hole edge of the through hole 54 to the front side in the fitting direction. It has a cylindrical shape.

Similarly, the through hole 54 is smaller than the opening size (maximum opening size) at the front end of the second guide surface 17 and larger than the opening size (minimum opening size) at the rear end of the second guide surface 17. Have dimensions.

  The seal walls 52 and 53 are formed symmetrically about the seal body 51. Further, the inner peripheral surfaces of the seal walls 52 and 53 are configured to be flush with the inner peripheral surface of the through hole 54 and extend in the fitting direction. On the other hand, the outer peripheral surfaces of the seal walls 52 and 53 are formed in a tapered shape that approaches the axial center side of the through hole 54 as the distance from the seal body 51 increases. Further, when the seal plate 50 is sandwiched between the opposing surfaces 16 and 35, the outer peripheral surface of the male side seal wall 52 contacts the first guide surface 36 over the entire periphery, and the female side seal wall 53 The outer peripheral surface is in contact with the second guide surface 17 over the entire periphery. As a result, the space between the female housing 30 and the seal plate 50 is sealed, and the space between the male housing 10 and the seal plate 50 is sealed. Therefore, the space spanning the male cavity 13, the male insertion hole 15, the through hole 54, the female insertion hole 34, and the female cavity 32 is a water-stopped space.

  As shown in FIG. 4, a plurality of holding ribs 55 are formed on the outer periphery of the seal body 51. These holding ribs 55 are arranged on four sides, two on each side, and are arranged at substantially equal intervals on the outer periphery of the seal body 51. Therefore, when the seal plate 50 is mounted inside the hood portion 12, each holding rib 55 comes into contact with the inner peripheral surface of the hood portion 12, so that the seal plate 50 can be held inside the hood portion 12.

  Next, an example of a method for fitting the male housing 10 and the female housing 30 will be described. First, as shown in FIG. 1, the seal plate 50 is mounted inside the hood portion 12 of the male housing 10 prior to the fitting of the housings 10 and 30. When the seal plate 50 is pushed into the hood portion 12, the seal plate 50 moves within the hood portion 12 while maintaining its shape as a single unit, and the male side seal wall 52 eventually becomes the second as shown in FIG. It abuts on the guide surface 17. Further, the holding ribs 55 are in contact with the inner peripheral surface of the hood portion 12 at substantially equal intervals. Thus, the mounting of the seal plate 50 on the male housing 10 is completed. At this time, the through holes 54 and 54 of the seal body 51 are arranged coaxially with the male insertion holes 15 and 15, and the male side seal wall 52 contacts the second guide surface 17 over the entire circumference. It will be in contact.

  Next, when the female housing 30 is pushed into the hood portion 12 of the male housing 10, the first guide surface 36 comes into contact with the female-side seal wall 53, and both the housings 10 and 30 are brought into a normal fitting state. At the same time that each terminal 20, 40 is in a normal connection state, the lock arm 37 that has been bent and deformed so as to get over the lock receiving portion 18 in the middle of the fitting, gets over the lock receiving portion 18 and is elastically restored. 30 is locked in a proper fitting state.

  In a properly fitted state of both housings 10, 30, the female-side seal wall 53 contacts the first guide surface 36 over the entire periphery, and the male-side seal wall 52 extends over the entire periphery of the second guide surface 17. It comes into contact. In this way, in the normal fitting state of both the housings 10 and 30, the space between the male housing 10 and the seal plate 50 and the space between the seal plate 50 and the female housing 30 are sealed, so that the space between both the housings 10 and 30 is sealed. Is done.

  As described above, in the present embodiment, the seal plate 50 made of a synthetic resin harder than rubber is used to seal between the housings 10 and 30, so that the positional deviation and deformation of the seal plate 50 can be eliminated. It is possible to prevent a decrease in waterproofness due to the displacement or deformation of the seal member. Thereby, between both the housings 10 and 30 can be sealed reliably. In addition, since the seal plate 50 can be held in the hood portion 12 in advance, it is easy to fit the housings 10 and 30 together. Further, since the seal walls 52 and 53 of the seal plate 50 are brought into contact with the guide surfaces 17 and 36 to sandwich the seal plate 50, the seal body 51 is brought into contact with the opposing surfaces 16 and 35. Sealing can be performed with a stronger contact pressure than when the sealing plate 50 is sandwiched.
