For realizing above-mentioned purpose; The connector with dust cap of the utility model adopts following technical scheme: a kind of connector with dust cap; Comprise housing, have the endoporus before and after connecting in the housing, the endoporus hole wall of said housing be provided be used for intermateable connector on the locking annular groove of the tapered end snap-fit that is provided with; The locking annular groove is the enlarging conical surface forward near the leading flank of the inserted terminal of connector and intermateable connector grafting; The endoporus leading portion that housing is used to hold intermateable connector is inserted with dust cap, and dust cap comprises the cylindrical body that the leading portion of outer peripheral face cooperates with the endoporus of housing, and the rear end of cylindrical body has the shutoff edge that cylindrical body is sealed up; The front end of the outer peripheral face of cylindrical body has the bulge loop with locking annular groove snap-fit; The trailing flank of bulge loop is the enlarging conical surface forward, and the outer peripheral face leading portion of cylindrical body has the inside axial groove of cutting of the front end face by cylindrical body that is divided into the plural elastic claw that overhangs forward, and axial groove is divided into plural lock dog with said bulge loop.
Rear side in elastic claw on the outer peripheral face of described cylindrical body is provided with the sealing ring that cooperates with housing seal.
The leading flank of the inserted terminal of pegging graft near connector and intermateable connector of said locking annular groove is the enlarging conical surface forward.
The following technical scheme of employing of the dust cap of the connector with dust cap of the utility model:
A kind of dust cap with connector of dust cap; The leading portion that comprises outer peripheral face is used for the cylindrical body that cooperates with the endoporus of the housing of connector; The rear end of cylindrical body has the shutoff edge that cylindrical body is sealed up; The front end of the outer peripheral face of cylindrical body has the bulge loop of the locking annular groove snap-fit on the housing inner peripheral surface that is used for connector; The trailing flank of bulge loop is the enlarging conical surface forward, and the outer peripheral face leading portion of cylindrical body has the inside axial groove of cutting of the front end face by cylindrical body that is divided into the plural elastic claw that overhangs forward, and axial groove is divided into plural lock dog with said bulge loop.
Be provided with in the rear side of elastic claw on the outer peripheral face of described cylindrical body and be used for the sealing ring that cooperates with the housing seal of connector.
The endoporus leading portion of the housing of the connector of the utility model is inserted with dust cap; The leading portion of the cylindrical body of dust cap has plural elastic claw; The locking annular groove snap-fit of lock dog on the front end of each elastic claw and connector shell; This only makes and to exist enough big axial force to make under the situation of elastic claw contraction; Dust cap just can be by taking off on the connector, and being connected between dust cap and the connector is reliable, even if use in having the environment of vibrations dust cap to take off on also can be by connector.
The dust cap of the utility model is to be plugged in the endoporus of housing of connector; And the dust cap of intermateable connector of the prior art is arranged on the periphery of the leading portion of intermateable connector; Simultaneously the leading portion of intermateable connector is plugged in the endoporus of housing of connector, and like this, dust cap can cooperate with the dust cap of intermateable connector; When plug and socket plug together; Dust cap can be plugged in the dust cap of intermateable connector, and two dust caps cooperate can prevent that dust or moisture from getting in the dust cap, thus the cleaning that keeps plug and socket.
