突起部を有する構成としている。In order to achieve the above object, the present invention provides an outer circumferential wall of one of the male and female connector housings, a rising rear wall provided along the outer circumferential wall, and a rising rear wall extending from the tip of the rising rear wall to the outer circumferential wall. A void space formed by a waterproof wall provided opposite to the space has packing therein,
The other connector housing has a sleeve portion that fits into the cavity, and in a waterproof connector in which the male and female connector housings are hermetically fitted through the packing, the packing is connected to an inner wall of the cavity and the housing portion. The main body portion is pressed into contact between the main body portion and the protrusion portion is pressed against the rising rear wall and the tip of the sleeve portion.
以下に本発明の実施例を図を用いて説明する。 Embodiments of the present invention will be described below with reference to the drawings.

体部の先端２ｄに圧接され得るように形成されている。An annular packing 4 is fixedly installed in a cavity 3 formed in the male connector housing 1, and the annular packing 4 has a shape as shown in the perspective view of FIG. 3(a). That is, the end surface 4d of the packing is extended to form a protrusion 4h which is an annular collar. As shown in FIG. 2, this protrusion 4h is formed so that it can be pressed against the rising rear wall of the male connector housing 1 and the tip 2d of the sleeve portion of the female connector housing 2 when mated.

生じなくなるので、接続不良を生じることもない。At this time, the protrusion 4h of the packing 4 is sandwiched between the tip 2d of the sleeve 2a and the rising rear wall lb, so that once the connector housings 1 and 2 are fitted and locked, they will move in the fitting direction. It becomes impossible to slide. Therefore, the terminal fittings will not slide against each other, and the terminal fittings will not wear out, so that connection failures will not occur.

不要となり、作業能率が向上する。A locking projection 4f is formed on the packing 4, and a through hole 1g is formed in the rising rear wall 1b, into which the locking projection 4f is inserted. The length of the locking projection 4f is longer than the thickness of the rising rear wall 1b, and after passing through the through hole 1g, it is heated and deformed using a trowel or the like to form the head 4g. By doing so, there is an advantage that the packing 4 is firmly fixed in the cavity 3, and at the same time, it becomes possible to easily confirm from the outside that the packing 4 is fixed. By the way, this locking protrusion 4r has a third
As shown in Figure 2), a head 4g may be formed in advance so that the head 4g of the locking protrusion rises and protrudes to the opposite side of the rear wall. In this case, there is no need to heat and deform the material using a trowel or the like, improving work efficiency.

できる。According to the present invention, in the waterproof connector, the waterproof packing has a raised rear wall forming the bottom of the cavity and a protrusion that is pressed against the tip of the sleeve. Therefore, it is possible to elastically prevent the male and female connector housings from sliding in the fitting direction after they are fitted, and thereby it is also possible to suppress the sliding of the terminal fittings provided in the connector housing.
そのため、端子金具の摩耗による接続不良を防止できる
という格別の効果がある。Therefore, there is a special effect in that poor connection due to wear of the terminal fittings can be prevented.
