The invention relates to a waterproof grommet having a first member ( ) and a second member ( ). The first member ( ) has a first sealing part ( ) formed on the inner surface of a through-hole ( ) through which an electrical wire connected to a contact is passed. The first sealing part ( ) adheres tightly to the electrical wire. The second member ( ) has a second sealing part ( ) formed on the outer surface of the through-holes ( ) that adheres tightly to the connector housing ( ). The first member ( ) is formed from an elastic material that has a lower hardness than that of the second member ( ). As a result, splitting of the inner surface of the through-holes ( ) is prevented without causing any deterioration of the waterproof properties of the joint between the connector housing and the waterproof grommet.

Waterproof grommet

The present invention provides a relatively compact electrical connector which is equipped with a resilient latching mechanism ( ) on one side of a housing ( ), and which accommodates a plurality of different types of electrical contacts inside the housing. The housing ( ) of the electrical connector ( ) has relatively-small first cavities ( ) which accommodate electrical contacts ( ) that have contact lances ( ), and relatively-large second cavities ( ) which have housing lances ( ) used to latch electrical contacts ( ). Mold-release apertures ( ) used to form the housing lances ( ) are located inside rigid walls ( ) that protect the resilient latching arm ( ) from both sides and mold-release apertures ( ) used to form latching shoulders ( ) are located in another side of the housing opposite the one side of the housing.
