Socket with a cover lock
A socket comprising a body having an opening in which a contact-holder is housed, a cover articulated to the body and movable between a closed position in which it closes said opening and an open position in which it is raised from said opening, a yoke articulated to the body and movable between a lowered position and a raised position, the yoke having two arms which, in the lowered position, are intended to cooperate with a shoulder of a plug to retain the plug inserted into the socket, and a latch member articulated to the yoke and movable with respect to the yoke between a locked position and an unlocked position, the latch member having at least one pawl which, in the locked position, engages a corresponding seat of the body and which, in the unlocked position, is disengaged from said seat, and a cover-lock element articulated to the body and movable between an engaged position and a disengaged position, wherein the latch member has at least one cam portion that cooperates with the cover-lock element for moving the cover-lock element from the engaged position to the disengaged position when the latch member moves from the locked position to the unlocked position.
1. A socket comprising:
a body having an opening in which a contact-holder is housed,
a cover articulated to the body and movable between a closed position in which it closes said opening and an open position in which it is raised from said opening,
a yoke articulated to the body and movable between a lowered position and a raised position, the yoke having two arms which, in the lowered position, are intended to cooperate with a shoulder of a plug to retain the plug engaged with the socket,
a latch member articulated to the yoke and movable relative to the yoke between a locked position and an unlocked position, the latch member having at least one pawl which, in the locked position, engages a corresponding seat of the body and which, in the unlocked position, is disengaged from said seat,
a cover-lock element articulated to the body and movable between an engaged position and a disengaged position, wherein the cover-lock element, in the engaged position, couples with the cover and locks the cover in the closed position, wherein the latch member has at least one cam portion that cooperates with the cover-lock element for moving the cover-lock element from the engaged position to the disengaged position when the latch member moves from the locked position to the unlocked position.
2. A socket according to claim 1 , wherein said latch member has two levers joined together by a transverse element, said levers having respective pressure zones, wherein said latch member rotates from the locked position to the unlocked position following a pressure on either one of said pressure zones.
3. A socket according to claim 2 , wherein each of said levers has a respective cam portion, said cam portions cooperating with lateral appendages of said cover-lock element.
4. A socket according to claim 2 , wherein each of said levers has a respective arm having a respective pawl.
5. A socket according to claim 1 , wherein said cover-lock element is elastically pushed toward said engaged position.
6. A socket according to claim 1 , wherein said cover-lock element is articulated to the body around a pin parallel to a pivot pin of the cover and located on an opposite side of said opening with respect to the pivot pin of the cover.
7. A socket according to claim 1 , wherein the cover-lock element is in the disengaged position when the cover is in the open position.
