Waterproof connector
View Patent ↗The present invention is to provide a waterproof connector having an adjusted spacing between terminals or electrical wires for achieving an effective waterproof. The electrical wires received in a terminal receiving portion of an outer housing are guided to a wire seal fit portion, while the electrical wires are pressed with wire holders (displacement limit portions). The electrical wires are then passed through a holder (spacing adjusting portion), a seal member, and another holder (lead-out portion) of a wire seal in the wire seal fit portion. The wire seal is fitted into the wire seal fit portion for achieving waterproof of the waterproof connector. The electrical wires guided out of the lead-out portion have an equal spacing therebetween by expansion of the spacings between the electrical wires or displacements thereof. The equal spacing ensures insertion of the seal member and provides the effective waterproof.
1. A waterproof connector comprising:
an outer housing including a terminal receiving portion and a wire seal fit portion, wherein
the terminal receiving portion includes a plurality of terminal receiving chambers, and the terminal receiving chambers receive a plurality of terminals connected with electrical wires having a first spacing; and
the wire seal fit portion includes a wire seal, the wire seal including
a lead-out portion for guiding outside the electrical wires having a second spacing,
a seal member, formed of a seal upper portion, seal lower portion and seal middle portions which form insertion holes through which the electric wires pass, disposed between the terminal receiving portion and the lead-out portion for allowing the plurality of the electrical wires to pass therethrough, and
a spacing adjusting portion disposed between the terminal receiving chambers and the seal member, the spacing adjusting portion having insertion portions arranged to adjust the first spacing of the electric wires to said second spacing.
2. The waterproof connector as claimed in claim 1 , wherein the spacing adjusting portion adjusts at least two different adjacent first spacings of the electrical wires to the second spacing, which is larger than the narrowest spacing among the at least two different spacings.
3. The waterproof connector as claimed in claim 1 , wherein the terminal receiving portion includes an inner housing having a plurality of inner plates piled-up on each other, each inner plate having the plurality of the terminal receiving chambers disposed in parallel, and each inner plate has a displacement limit portion at an outer surface of a rear end portion thereof for limiting displacement of the electrical wires disposed below to a prescribed quantity.
4. The waterproof connector as claimed in claim 1 , wherein the outer housing has a packing at a rear end portion of the terminal receiving portion, the packing abutting on a front end of an outer circumference portion of the wire seal fit portion for keeping water-tight between the waterproof connector and a mating connector.
5. The waterproof connector as claimed in claim 1 , wherein the spacing adjusting portion includes a plurality of spacing adjusting plates piled-up on each other.
6. The waterproof connector as claimed in claim 5 , wherein the plurality of the spacing adjusting plates are integral with a seal member.
