Abstract
An operating mechanism for a plugboard system to connect and disconnect electrical terminals of a front bay with respective electrical terminals of a rear bay comprises hanger plates and sliding cam plates mounted on a rear frame, the cam plates having profiled cam slots and L-shaped slots therein. An operating member is pivotally mounted into the rear frame and includes rollers which are disposed in the L-shaped slots so that when the operating member is moved from one position to another position, the rollers move along the L-shaped slots causing the cam plates to move along the rear frame which causes the cam slots to linearly move support members on a front frame thereby connecting or disconnecting the electrical terminals.
Claims12
An operating mechanism for a plugboard system or the like to connect and disconnect electrical terminals of a front bay with respective electrical terminals of a rear bay, comprising:
- a rear bay comprising a rear frame in which a rear panel having rows of electrical terminals is mounted;
- hanger plates mounted onto opposite side members of the rear frame in alignment with each other and including guide slots therein, the hanger plates serving to receive in the guide slots thereof support members extending outwardly from side members of a front frame of the front bay;
- sliding cam plates mounted on the rear frame and being movable along the hanger plates and having spaced profiled cam slots therein, the cam slots having entrance sections, angled sections and straight sections, the entrance sections extending parallel to the guide slots, the straight sections being disposed generally normal to the entrance sections and the angled sections extending between the entrance sections and the straight sections;
- and
- an operating member mounted onto the rear frame to move said cam plates in unison relative to said hanger plates between an inoperative position and an operative position, said operating member including a shaft extending through L-shaped openings in the cam plates, arms secured to said shaft and having bearing means thereon which are disposed in respective L-shaped openings, said bearing means being movable in said L-shaped openings when said shaft is moved by operation of said operating member to move the cam plates between said inoperative and said operative positions, so that with the support members positioned in the respective guide slots of the hanger plates and moved into said entrance sections of the cam slots, the sliding cam plates move along the side members of the rear frame causing the angled sections and the straight sections of the cam slots to move the support members along the guide slots in a straight inward direction thereby electrically connecting the respective electrical terminals of the front and rear bays together.
An operating mechanism for positioning a first panel member in operative relationship with a second panel member so that associated mating electrical terminals in the first and second panel members can be electrically connected or disconnected when the panel members are moved relative to each other, comprising:
- a rear frame in which the second panel member is mounted and having side members;
- hanger plates mounted on the side members opposite and in alignment with each other and having straight guide slots therealong;
- sliding cam plates mounted on respective side members extending adjacent to said hanger plates and having spaced profiled cam slots including entrance sections, angled sections and straight sections, said entrance sections in one position of the cam plates register with respective guide slots of said hanger plates, said straight sections being substantially normal relative to said entrance sections and said angled sections extending between said entrance sections and said straight sections;
- a front frame in which the first panel member is mounted, supporting members on side sections of the front frame, said supporting members adapted to be positioned in respective guide slots of said hanger plates;
- and
- operating means on said rear frame to move said cam plates in unison relative to said hanger plates between an inoperative position and an operative position, said operating means including a shaft extending through L-shaped openings in said cam plates, arm means secured to said shaft and having bearing means on said arm means which are disposed in respective L-shaped openings, said bearing means being movable in said L-shaped openings when said shaft is moved to move the cam plates between the inoperative position and the operative position, so that with said cam plates in their inoperative position and when the supporting members of the front frame are in their respective guide slots of said hanger plates and moved into said entrance sections of said cam slots, movement of said cam plates under the action of said operating means to said operative position causes said angled sections and straight sections of said cam slots to move said supporting members along said guide slots in a straight inward direction thereby electrically connecting the electrical terminals of the first panel member with respective electrical terminals of the second panel member.
