Connector with locking mechanism and connector device
Prior-art connectors require burdensome operations that involve connecting the male screws of the threaded retaining members mounted on an overmolded connector unit to the internal threads provided in a counterpart connector and tightening the screws by turning in order to prevent connector disengagement. In addition, repeatedly attaching and detaching the connector may create a problem by increasing the burden of such operations. The present invention provides a connector and a connector device that allows for easy attachment to and detachment from a counterpart connector by providing a locking mechanism that automatically locks upon connection to a counterpart connector and that permits unlocking by depressing buttons in a connector that includes a connector unit provided in a distal end section of a cable and a housing that holds said connector unit inside and is equipped with a locking mechanism for locking to a counterpart connector.
1. A connector, comprising:
a connector unit comprising a raised mating portion; and
a housing that holds the connector unit and is equipped with locking members, the housing comprising a first housing case, a second housing case, and housing position regulating portions disposed on the first housing and the second housing case, wherein
the raised mating portion is exposed by the housing in a central section in a direction of mating,
the housing comprising raised engaging portions that project in the direction of mating so as to sandwich the raised mating portion on opposite sides thereof,
the locking members comprising locking pawls at the distal ends and operative locking portions at the rear ends,
the raised engaging portions have the locking pawls exposed thereon,
a gap is provided between the connector unit and the inner walls of the housing facing the connector unit, and
the connector unit is configured to float within the housing by virtue of the gap.
2. The connector according to claim 1 , wherein
the gap is provided around the periphery of the connector unit held in the housing and
the connector unit can move in any direction within a motion range defined by the gap.
3. The connector according to claim 1 , wherein
the locking pawls are exposed on the lateral faces of the raised engaging portions facing the raised mating portion of the connector unit and
the locking pawls protrude in the direction of the raised mating portion.
4. The connector according to claim 1 , wherein
the locking pawls are exposed on the lateral faces opposite to the lateral faces of the raised engaging portions facing the raised mating portion of the connector unit and
the locking pawls protrude in the direction opposite to the direction of the raised mating portion.
5. The connector according to claim 1 , wherein
the distal ends of the raised engaging portions and the distal end of the raised mating portion are substantially aligned in the direction of mating.
6. The connector according to claim 1 , wherein
the operative locking portions are exposed on the lateral faces of the housing and
the locking pawls move in the width direction in response to depression of the operative locking portions.
7. The connector according to claim 1 , wherein
the connector unit comprises unit position regulating portions,
and
the position of the connector unit within the housing is regulated by virtue of engagement of the unit position regulating portions with the housing position regulating portions.
8. The connector according to claim 1 , wherein
the locking members are disposed within the housing on opposite sides of the connector unit in the width direction.
9. The connector according to claim 1 , wherein
the locking members comprises resilient spring strips,
the spring strips abut the inner walls of the housing, and, upon connection to a counterpart connector, automatically enter a locked state and maintain said state by virtue of the resilience of the spring strips.
10. The connector according to claim 1 , wherein the connector unit conforms to the USB (Universal Serial Bus) Type-C Standard.
11. A system comprising:
a connector, comprising:
a connector unit comprising a raised mating portion; and
a housing that holds the connector unit and is equipped with locking members, the housing comprising a first housing case, a second housing case, and housing position regulating portions disposed on the first housing case and the second housing case, wherein
the raised mating portion is exposed by the housing in a central section in a direction of mating,
the housing comprising raised engaging portions that project in the direction of mating so as to sandwich the raised mating portion on opposite sides thereof,
the locking members comprising locking pawls at the distal ends and operative locking portions at the rear ends,
the raised engaging portions have the locking pawls exposed thereon,
a gap is provided between the connector unit and the inner walls of the housing facing the connector unit, and
the connector unit is configured to float within the housing by virtue of the gap and a counterpart connector connected to the connector, the counterpart connector comprising:
a connector main body portion that has a recessed mating portion for mating with the raised mating portion;
a counterpart housing that is a separate component from the counterpart connector and has recessed engagement portions for receiving the raised engaging portions, and
the recessed engagement portions are equipped with locking apertures adapted to engage the locking pawls exposed on the raised engaging portions.
