Circular connector assembly
View Patent ↗A temporary locking projection for mounting the engaging ring at a reference position for assembly, and a detecting locking projection positioned forward of the temporary locking projection in a rotating direction of the engaging ring are provided on an outer periphery of the male connector housing and projected outward in a radial direction thereof. A temporary locking wall extending in an axial direction of the engaging ring for engaging with the temporary locking projection, and a resilient locking arm having a locking hook at an inner distal end surface are provided on an outer surface of the engaging ring. The locking hook is engaged with the detecting locking projection. A contact surface for contacting the resilient locking arm is provided at a projecting end of the detecting locking projection. A step having a contact surface for contacting the contact surface of the detecting locking projection is provided on the resilient locking arm.
1. A circular connector assembly comprising:
a rotatable engaging ring arranged in between male and female connectors for moving the connectors in a direction of engaging the connectors with each other;
a detector being provided on an outer surface of one of the male and female connectors on which the engaging ring is mounted, for detecting a fitting state of the connectors and preventing the engaging ring from rotating in a reverse direction; and
a resilient locking arm being provided to form a free end on the engaging ring, extending in a rotating direction of the engaging ring for engaging with the detector,
wherein the resilient locking arm intersects with a support projecting from an outer peripheral wall of the engaging ring,
wherein a locking part and an unlocking part are provided integrally on both sides of the locking arm respectively.
2. The circular connector assembly as claimed in claim 1 , further comprising:
a temporary locking projection provided on an outer peripheral wall of one of the male and female connectors on which the engaging ring is mounted; and
a temporary locking wall provided on the engaging ring to be engaged with the temporary locking projection for locking the engaging ring at a reference position for assembly.
3. The circular connector assembly as claimed in claim 1 , further comprising:
protecting walls provided on the engaging ring at both sides of the resilient locking arm in a circumferential direction of the engaging ring; and
a coupling wall provided on the engaging ring along the resilient locking arm in the circumferential direction of the engaging ring for coupling the protecting walls, wherein the protecting and coupling walls are taller than the resilient locking arm projecting from the engaging ring.
4. The circular connector assembly as claimed in claim 1 , wherein the detector is a locking projection having a contact surface for contacting the resilient locking arm, wherein the resilient locking arm includes a step having a contact surface for contacting the contact surface of the locking projection.
5. A circular connector assembly comprising:
a rotatable engaging ring arranged in between male and female connectors for moving the connectors in a direction of engaging the connectors with each other;
a detector being provided on an outer surface of one of the male and female connectors on which the engaging ring is mounted, for detecting a fitting state of the connectors and preventing the engaging ring from rotating in a reverse direction; and
a resilient locking arm being provided to form a free end on the engaging ring, extending in a rotating direction of the engaging ring for engaging with the detector,
wherein the detector is a locking projection having a contact surface for contacting the resilient locking arm,
wherein the resilient locking arm includes a step having a contact surface for contacting the contact surface of the locking projection,
wherein a slope is provided on a rear of the detector in a rotating direction of the engaging ring,
wherein a locking surface is provided on a front side of the detector in a rotating direction of the engaging ring,
wherein a locking hook, to be passed over the slope and locked on the locking surface of the detector, is projected inwardly from the resilient locking arm.
6. The circular connector assembly as claimed in claim 5 , wherein when the engaging ring is rotated in a reverse direction, the locking hook of the resilient locking arm so contacts the locking surface of the detector as to be drawn inwardly in a radial direction of the engaging ring.
