Latch mechanism for a header
| Details |
Inventors: Layser, Steven M.;
Assignee: AMP Incorporated (Harrisburg, PA)
Primary Examiner: Pirlot; David L.
Assistant Examiner:
Attorney, Agent or Firm:
A latch mechanism (4) of an electrical header (1) comprises, a lever member (5) pivotally mounted on an end of the header (1) and being adapted for close spacing from a similar lever member (5) of a second electrical header (1), the lever member (5) being adapted to nest against an exterior of the similar lever member (5), and an actuation arm (10) pivotal with the lever member (5) to overlap the similar lever member (5), a reinforcing rib extending beside the arm (10), and a gripping surface (11) along the arm (10). |

DETAILED DESCRIPTION With reference to the drawings, an electrical header 1 comprises a housing 2, electrical terminal pins 15 in the housing 2, and the housing 2 being adapted for receiving an electrical device 3, such as, an electrical connector disclosed in U.
S.
Pat.
No.
4,178,051, or such as, a circuit card, not shown.
Further details of the header 1 are disclosed, for example, in U.
S.
Pat.
No.
4,178,051.
A latch mechanism 4 of the electrical header 1 includes a lever member 5 pivotally mounted by a pivot pin 6 on an end 7 of the header 1.
The pin 6 provides a pivot for the latch mechanism 4.
Opposite ends 7 of the header 1 are provided with a pivotally mounted latch mechanism 4, although the description herein describes one latch mechanism 4 at one end 7.
A latching arm 8 is on the lever member 5 with a shoulder 9 adapted to engage an electrical device 3 mated to the header 1.
An actuation arm 10 is on the lever member 5.
The actuation arm 10 projects from the lever member 5, and is adapted to receive the application of a force to pivot the latching arm 8 in a direction outwardly of the header 1 to disengage the shoulder 9 of the latching arm 8 from the electrical device 3.
A gripping surface 11 is on the actuation arm 10 to facilitate a firm grip when a person's finger applies a force to the gripping surface 11 to pivot the lever member 5 and the latching arm 8 in a direction outwardly of the header 1 to disengage the latching arm 8 from the electrical device 3.
When the latching arm 8 is thus disengaged, the electrical device 3 can be removed from the header 1.
In one type of header 1, the electrical device 3 is ejected by an eject lever 12 attached to the lever member 5.
The eject lever 12 extends outwardly from the pivot pin 6 and is adapted to be engaged by an electrical device 3 inserted into the header 1.
The eject lever 12 is on the lever member 5.
Pivoting of the lever member 5 in a direction outwardly of the header 1 will pivot the eject lever 12.
The eject lever 12 when pivoted will urge against the electrical device 3, and will lift the electrical device 3 and, thereby, eject the electrical device 3
