Wire seal having a body with a projection insertable into a contact insertion passageway
View Patent ↗A waterproof connector is provided with a connector housing and a wire seal. The connector housing includes a plurality of first contact insertion passageways. The wire seal includes a wire seal body and at least one projection. The wire seal body includes a plurality of second contact insertion passageways disposed at positions corresponding to the plurality of first contact insertion passageways and receive a plurality of contacts pressed tightly against edges of inner perimeters of the plurality of second contact insertion passageways to seal the plurality of second contact insertion passageways when the contacts are inserted through the plurality of second contact insertion passageways. The at least one projection extends from the wire seal body and is disposed along positions corresponding to any of the plurality of first contact insertion passageways. The plurality of second contact insertion passageways are insertable through the first contact insertion passageway.
1. A wire seal received in a connector housing having a plurality of first contact insertion passageways, the wire seal comprising:
a wire seal body having a plurality of second contact insertion passageways disposed at positions corresponding to the plurality of first contact insertion passageways and receiving contacts that are pressed tightly against edges of inner perimeters of the plurality of second contact insertion passageways to seal the plurality of second contact insertion passageways when the contacts are inserted through the plurality of second contact insertion passageways; and
at least one projection extending from the wire seal body and disposed at a position corresponding to at least one of the plurality of first contact insertion passageways and insertable into the at least one of the plurality of first contact insertion passageways wherein the at least projection is inserted into the at least one of the plurality of first contact insertion passageways which is left as hollow space without a contact inserted therein.
2. The wire seal according to claim 1 , further comprising a plurality of ridges disposed on an inner surface of each of the plurality of second contact insertion passageways.
3. The wire seal according to claim 2 , wherein the plurality of ridges are configured to closely adhere to an outer surface of each of the wires inserted through the plurality of second contact insertion passageways.
4. A waterproof connector, comprising:
a connector housing having a plurality of first contact insertion passageways; and
a wire seal having:
a wire seal body having a plurality of second contact insertion passageways disposed at positions corresponding to the plurality of first contact insertion passageways and receiving a plurality of contacts that are pressed tightly against edges of inner perimeters of the plurality of second contact insertion passageways to seal the plurality of second contact insertion passageways when the plurality of contacts are inserted through the plurality of second contact insertion passageways; and
at least one projection extending from the wire seal body and disposed at a position corresponding to at least one of the plurality of first contact insertion passageways and insertable into the at least one of the plurality of first contact insertion passageways wherein the at least projection is inserted into the at least one of the plurality of first contact insertion passageways which is left as hollow space without a contact inserted therein.
5. The waterproof connector according to claim 4 , wherein the connector housing includes a contact insertion face through which the plurality of contacts are inserted and the at least one projection is high enough to be seen from the contact insertion face when the wire seal is inserted into the connector housing.
6. The waterproof connector according to claim 5 , wherein the at least one projection extends through the at least one of the plurality of first contact insertion passageways and beyond the contact insertion face.
7. The wire seal according to claim 4 , further comprising a plurality of ridges disposed on an inner surface of each of the plurality of second contact insertion passageways.
8. The wire seal according to claim 7 , wherein the plurality of ridges are configured to closely adhere to an outer surface of each of the wires inserted through the plurality of second contact insertion passageways.
