Locking and unlocking mechanism of cable connector and method for locking and unlocking
First Claim
1. A locking and unlocking mechanism for locking and unlocking a connector, comprising a cable holding member for holding an end of a cable and a lock release member slidably attached to the outside of the cable holding member, to a housing for receiving said connector and for conducting the cable;
- wherein, at the time of inserting the connector, a pushing operation of the lock release member allows connection of the lock release member to the housing by setting the lock release member at a set position by engaging of an engaging pawl provided with one of the cable holding member or the lock release member with an engaging portion provided with the other one of the cable holding member and the lock release member by pushing up an elastic beam portion provided in one of the cable holding member and the lock release member by means of an inclined plane provided with the other one of the cable holding member and the lock release member, wherein pushing up of the elastic beam portion causes the storage of elastic energy;
at the time of extracting the connector, the connector is released from the housing by sliding the lock release member in a releasing direction for pushing up the elastic beam portion by a protrusion; and
the lock and unlock mechanism configured to enable the stored elastic energy to automatically move the lock release mechanism to the set position and to the reset position at the time of inserting and extracting the connector.

Abstract
A locking and unlocking mechanism of a cable connector, consisting of a connector and a housing, and a method for locking and unlocking the cable connector capable of providing a reliable connection of a cable even when a cable connecting operation is carried out by holding the cable. The connector is unlocked from the housing by sliding the lock release mechanism from the set position to the release position when the connector is fitted in the housing. At the time of connecting the cable, when the cable holding member is inserted into the housing while holding the cable, the elastic beam portion of the housing is pushed to open by the protrusion of the lock release member, and the engaging hole formed in the elastic beam portion is engaged with the engaging pawl of the cable holding member, and the connector is installed into the housing by moving the lock release member to the set position by the elastic energy of the lock release member from the elastic deformation caused by being pushed by the cable holding member.

1. A locking and unlocking mechanism for locking and unlocking a connector, comprising a cable holding member for holding an end of a cable and a lock release member slidably attached to the outside of the cable holding member, to a housing for receiving said connector and for conducting the cable;
-
wherein, at the time of inserting the connector, a pushing operation of the lock release member allows connection of the lock release member to the housing by setting the lock release member at a set position by engaging of an engaging pawl provided with one of the cable holding member or the lock release member with an engaging portion provided with the other one of the cable holding member and the lock release member by pushing up an elastic beam portion provided in one of the cable holding member and the lock release member by means of an inclined plane provided with the other one of the cable holding member and the lock release member, wherein pushing up of the elastic beam portion causes the storage of elastic energy;
at the time of extracting the connector, the connector is released from the housing by sliding the lock release member in a releasing direction for pushing up the elastic beam portion by a protrusion; and
the lock and unlock mechanism configured to enable the stored elastic energy to automatically move the lock release mechanism to the set position and to the reset position at the time of inserting and extracting the connector. - View Dependent Claims (3, 8)

2. A locking and unlocking mechanism for locking and unlocking a connector, comprising a cable holding member for holding an end of a cable and a lock release member slidably attached to the outside of the cable holding member, to a housing for receiving said connector and for conducting the cable;
-
wherein the lock and unlock mechanism comprises;
in the connector, an engaging pawl provided in the cable holding member;
in the connector, a protrusion on a beam portion extended from the lock release member extending towards the housing;
in the housing, an engaging portion provided in an elastic beam portion, in which one side is opened for receiving said beam portion, provided with the engaging portion for engaging with said engaging pawl and a notch portion for receiving said protrusion;
wherein, when the connector is inserted, the lock release member is moved to a set position where the protrusion of the lock release mechanism is received by the notch portion in the elastic beam portion, and when the connector is extracted, the lock release mechanism is moved to the reset position with respect to the cable holding member;
wherein, the connector is connected to the housing by adjusting the engaging pawl of the lock release mechanism of the connector to the engaging portion of the housing by pushing up the elastic beam portion of the housing by means of the protrusion of the lock release mechanism of the connector, thereby storing elastic energy, and by moving the lock release member to the set position automatically using the elastic energy stored in the elastic beam portion. - View Dependent Claims (4)

5. A locking and unlocking mechanism for locking and unlocking a connector, comprising a cable holding member for holding an end of a cable and a lock release member slidably attached to the outside of the cable holding member, to a housing for receiving said connector and for conducting the cable;
-
wherein the lock and unlock mechanism comprises;
in the connector, an engaging pawl provided in the cable holding member;
in the connector, a protrusion on a beam portion extended from the lock release member extending towards the housing;
in the housing, an engaging portion provided in an elastic beam portion, in which one side is opened for receiving said beam portion, provided with the engaging portion for engaging with said engaging pawl and a notch for receiving said protrusion as well as a guide portion for guiding the distal end of the beam portion; and
the lock and release member, after the connector is extracted, for moving the lock release member to a set position where a top end of the beam portion is made flat, and when the connector is extracted, the connector is separated from the housing by releasing the engagement between the engaging pawl with the engaging portion by pushing up the elastic beam portion of the housing by bending the beam portion and thereby storing elastic energy, and by moving the lock release member to the reset position automatically using the elastic energy stored in the beam portion. - View Dependent Claims (6, 7)

9. A method for locking and unlocking a cable connector comprising a connector for holding an end of a cable and an elastically deformable lock release member slidably attached to the outside of the cable holding member and a housing comprising an elastic beam portion for receiving said connector and conducting the cable, the cable connector being unlocked by sliding the lock release member of the connector fitted in the housing from the set position to the release position,
wherein the method comprises: -
fitting the connector into the housing, at the time of inserting the connector, by the steps of;
inserting the cable holding member into the housing, pushing up the elastic beam portion by a part of the lock release member, engaging the engaging portion of the elastic beam portion with the engaging pawl of the cable holding member, and by moving the lock release member to the set position by the elastic energy of the elastically deformed lock release member caused by being pushed by the cable holding member; and
disconnecting the connector from the housing, at the time of extracting the connector, by the steps of;
extracting the lock release member, pushing up the elastic beam portion for releasing the engagement between the engaging portion of the elastic beam portion and the engaging pawl of the cable holding member and moving the lock release member to the reset position by the elastic energy of the lock release member caused by the elastic deformation after the connector is extracted.
