Abstract

An electrical connector includes a housing (1) defining a mating cavity (13) in a mating face thereof; terminals (2) loaded in the housing and each having a contact portion (21) exposed in the mating cavity; a shutter (4) covering the mating cavity and capable of sinking into the mating cavity to expose the contact portions of the terminals; and an elastic means (3) disposed between the shutter and the housing and provided with a elongated shaft member (33) aslant extending into the mating cavity to support the shutter. The shaft member is capable of rotating to a state substantially flatly lying between the housing and the shutter by pressure of the sinking shutter and will urge the sunk shutter to return to cover the mating cavity.

Claims

1. An electrical connector comprising:

a housing defining a mating cavity;

a plurality of terminals loaded in the housing and each having a contact portion exposed in the mating cavity;

a shutter covering the mating cavity in a first position thereof relative to the housing and being sinkable into the mating cavity to a second position to expose the contact portions of the terminals; and

an elastic means urging the shutter from the second position to the first position, the elastic means provided with an elongated shaft member aslant extending into the mating cavity to support the shutter in the first position, the shaft member sandwiched between the shutter and the housing while the shutter is at the second position.

2. The electrical connector as described in claim 1, further comprising a shell attached to a periphery of the housing, the shell having a bar for securing the shutter in the first position to prevent the shutter from jumping out of the mating cavity.

3. The electrical connector as described in claim 1, wherein the housing defines a guiding channel with an entry thereof sealed by the shell and the shutter is formed with a guiding ears moving back-and-forth in the guiding channel.

4. The electrical connector as described in claim 1, wherein the shaft member has a free end to slide on the shutter while the shutter sinking and the shaft member rotating.

5. The electrical connector as described in claim 4, wherein the shutter has a securing portion to hold the free end of the shaft member against from sliding while the shutter is in the first position.

6. The electrical connector as described in claim 1, wherein the elastic means is disposed in the mating cavity.

7. The electrical connector as described in claim 1, wherein the shaft member extends from a middle of a coil spring.

8. The electrical connector as described in claim 1, wherein the mating cavity has at least a tongue protruding from a bottom thereof, and the shutter defines a passageway for the tongue to pass through while the shutter sinking.

9. An electrical connector comprising:

an insulative housing defining an elongated receiving cavity with at least one mating tongue extending therein;

a plurality of contacts disposed on at least on surface of said mating tongue;

a shutter assembled to the housing and movable back and forth in said receiving cavity along a mating direction, said shutter defining an elongated slot dimensioned compliant wit a cross-section of said mating tongue; and

a resilient device urging said shutter toward a mating face of the housing to shield the receiving cavity when no complementary connector is mated;

wherein

said resilient device defines a deflectable member essentially swinging around a pivotal axis which extends in a horizontal direction parallel to the mating face while perpendicular to the mating direction, and wherein

said deflectable member abuts against a back face of the shutter in a parallel relation when said shutter is fully pushed to a final position in the receiving cavity.

10. The connector as claimed in claim 9, further including a guidance device on the shutter for assurance of no tilting of the shutter during back-and-forth movement along said mating direction.

11. The connector as claimed in claim 10, further including a complementary guidance device on the housing for interengaging the guidance device.

12. An electrical connector comprising:

an insulative housing defining an elongated receiving cavity with at least one mating tongue extending therein;

a shutter comprising a back face assembled to the housing and movable back and forth in said receiving cavity along a mating direction, said shutter defining an elongated slot dimensioned compliant with a cross-section of said mating tongue; and

a resilient device comprising a coil spring extending in a horizontal direction parallel to the mating face while perpendicular to the mating direction, a retaining leg extending from the coil spring and abutting on a bottom face of the receiving cavity, and a supporting member swingably extending from the coil spring and angularly disposed between the shutter and the bottom face of the receiving cavity for supporting the shutter toward a mating face of the housing to shield the receiving cavity when no complementary connector is mated.

13. The connector as claimed in claim 12, wherein the supporting member has a free end capable of sliding against the back face of the shutter.

14. The connector as claimed in claim 12, wherein the supporting member abuts against the back face of the shutter in a parallel relation when said shutter is fully pushed to a final position in the receiving cavity.

15. The connector as claimed in claim 12, wherein a the receiving cavity defines a room for fitly receiving the coil spring portion of the resilient device.
