DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A waterproof connector 100 according to an embodiment of the present invention is a receptacle connector type connector that is coupled with a plug connector (not shown). That is, the waterproof connector 100 according to the present embodiment is a female connector having a space in which a plug connector (not shown) is inserted.

The waterproof connector 100 according to the present embodiment includes outer housings 110 and 120, an inner housing 130 coupled to a rear end of the outer housings 110 and 120, A cable 150 connected to the terminal 140 and an over mold housing 160 surrounding a rear end portion of the outer housings 110 and 120.

The outer housings 110 and 120 are formed in a multi-stage structure including a body 110 and an extension 120 formed at a rear end of the body 110. A first engagement space 112 is formed in the body 110 to receive a plug connector (not shown). A second engagement space 122 is formed in the extension 120 to receive the inner housing 130. . At this time, the first engagement space 112 and the second engagement space 122 are separated into separate spaces by the rear surface of the body 110.

A fixing groove 114 for fixing the outer housings 110 and 120 to a mold (not shown) is formed on the lower surface of the body 110 when the overmold housing 160 is formed. When the fixing grooves 114 are used, the outer housings 110 and 120 are fixed to the mold, so that the shape and dimensions of the overmolded housing 160 can be uniformly formed.

A sealing jaw 124 is formed around the front end side of the extension 120 and a locking hole 126 is formed behind the sealing jaw 124. The sealing jaw 124 is for preventing foreign matter including moisture from flowing between the extension 120 and the overmolded housing 160 and has a ring shape protruding along the periphery of the extension 120. The latching hole 126 prevents the inner housing 130 mounted in the second engagement space 122 from being separated from the inner housing 130. The latching hole 126 has a shape corresponding to the latching protrusion 135 formed on the inner housing 130, (135) can be inserted and fixed.

Although not shown in the drawing, a guide groove (not shown) for guiding the engagement of the inner housing 130 is formed in the extension 120. When the inner housing 130 is engaged, the guide protrusion 136 moves along the guide groove (not shown) and guides the coupling direction.

The inner housing 130 is formed in a rectangular parallelepiped shape insertable into the second engagement space 122. A mounting hole 131 in which the terminal 140 is installed is formed in the inner housing 130. The mounting hole 131 is formed to penetrate the inner housing 130 in the front-rear direction. In this embodiment, the mounting holes 131 are illustrated as a pair in which the mounting holes 131 are arranged in parallel. However, the mounting holes 131 are not necessarily limited to the same number as the necessary number of terminals.
