Referring to FIG. 3 and FIG. 6, the capping unit 5 is used for providing the terminal 92. The cover unit 5 is disposed in the accommodating space 25 and covers the lead base 22, which can be pressed against the top ring groove unit 411 to force the bottom ring groove 421 of the seal ring 4 to be engaged with the convex portion. Rib 211. The capping unit 5 includes a first cap 51 and a second cap 52 covering the first cap 51. A bottom edge of the first cover 51 is inserted into the first ring groove 412 and has a plurality of terminal holes 511 corresponding to the lead-through holes 221. The bottom edge of the second cover 52 is inserted into the second ring groove 413 and has a terminal base 521 and four guide blocks 522. The terminal block 521 is provided for a plurality of terminals 92. The guide blocks 522 are formed in groups of two, which are respectively formed on two opposite sides of the second cover 52, and their positions correspond to the openings 244 of the surrounding wall 24.

Referring to FIG. 3 and FIG. 5, when installing, a wire 91 or a plurality of wires 91 are first penetrated from the wire grooves 231 of the housing 2 and are arranged in the wire holes 221 of the wire base 22. Next, the sealing ring 4 is placed in the accommodating space 25 and covers the guide. 线 座 22。 Line seat 22. Then, the first cover 51 is taken into the accommodating space 25, and the first cover 51 is placed on the lead base 22, and then the bottom edge is inserted into the first ring groove 412. As shown in FIGS. 3 and 7, next, the second cover 52 provided with a plurality of L-shaped terminals 92 is placed in the accommodation space 25, and each guide block 522 is placed in a corresponding one of the openings 244. in. See FIG. 6 and FIG. 8. Finally, the card member 3 is pushed, so that the guide blocks 522 are respectively guided by the guide chute 321, and the second cover 52 is forced to move toward the lead base 22. At this time, a baffle 523 inside the second cover 52 will abut against the first cover 51 and push it to displace in the same direction to be inserted into the second ring groove 413 and the first ring, respectively. In the groove 412, the bottom ring groove 421 of the seal ring 4 is forced to be engaged with the rib 211. It is worth mentioning that the bottom edge of the second cover 52 and the rib 211 are opposite to each other. Therefore, during installation, the second cover 52 and the rib 211 will gradually approach each other relatively, which can more effectively The effect of pinching the seal ring 4 and pressing the bottom ring groove 421 to be engaged with the rib 211 will be more significant, effectively improving its sealing performance.

Referring to FIG. 3, FIG. 7 and FIG. 8, when disassembling, as long as the card piece 3 is pulled out in the opposite direction, the guide blocks 522 will be respectively driven by the guide chute 321 to drive the second cover 52 Gradually away from the lead base 22. Continue to pull the card piece 3 until the guide grooves 321 communicate with the openings 244, respectively. At this time, the second cover 52 can be removed from the casing 2, and then the first cover is removed. 51, you can reconnect other wires 91. After mating, just follow the above installation steps.

Through the above description, the advantages of the present invention can be listed as follows:

1. The capping unit 5 can be pressed against the top ring groove unit 411 to force the bottom ring groove 421 of the sealing ring 4 to be engaged with the rib 211 to ensure the overall sealing performance.

2. The bottom edge of the second cover 52 and the rib 211 are opposite to each other. Therefore, during installation, the second cover 52 and the rib 211 will gradually approach each other relatively, which can more effectively pinch the seal. The effect of the ring 4 pressing the bottom ring groove 421 on the rib 211 will be more significant, effectively improving its sealing property.

Third, the present invention has three positions that can respectively press the sealing ring 4 to achieve the effect of sealing. The aforementioned positions are the bottom edges of the rib 211, the first cover 51, and the second cover 52, respectively. Thus, compared with the conventional design with only two closed positions, the waterproof effect of the present invention is obviously better.

4. The convex portions 414 are formed on the inner peripheral surface of the second ring groove 413, thereby increasing the strength of the joint with the second cover 52 and improving the sealing effect.

In summary, the capping unit 5 can be pressed against the top ring groove unit 411 to force the bottom ring groove 421 of the sealing ring 4 to be engaged with the rib 211 to ensure the overall sealing property. Therefore, It can really achieve the purpose of the invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited in this way, any simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the patent specification of the present invention are still Within the scope of the invention patent.
