Circuit board header and assembly

Claim 2

A header for protecting an array of pins fixed in a circuit board comprising an insulating housing moulded from plastics material with a portion defining a cavity for receiving a connector adapted to mate with the pins which cavity has a base wall opposite a connector admitting mouth, the base wall being provided with an array of apertures, a plurality of mounting legs integrally formed with the cavity defining portion and having resilient latching portions at free ends for receipt in apertures in the circuit board to mount the header one one side of the circuit board with the pins . extending through respective apertures into the cavity, characterised in that, the legs (21) are provided with longitudinally extending passageways (27) constituting sockets for receiving mounting legs (22) of another, similar, header (13) when mounted on the other side of the circuit board (9) with the pins (8) extending through respective apertures.

Claim 3

A header assembly for protecting an array of pins fixed in a circuit board to upstand from opposite sides of the board comprising first and second headers each comprising an insulating housing moulded from plastics material with a portion defining a cavity for receiving a connector adapted to mate with the pins which cavity has a base wall opposite a connector admitting mouth, the base wall being provided with an array of apertures, a plurality of mounting legs integrally formed with the cavity defining portion and having resilient latching portions at free ends for receipt in apertures in the circuit board to mount the header on one side of the circuit board with the pins extending through respective apertures into the cavity, characterised in that, the mounting legs (21) of the first header (12) are provided with longitudinally extending passageways (27) constituting sockets and the mounting legs (22) of the second header (13) are received in the sockets (27) to mount the second header (13) on the other side of the circuit board (9) with the pins (8) extending through respective apertures.

Claim 4

A header assembly for protecting an array of pins fixed in a circuit board to upstand from opposite sides of the board comprising first and second headers each comprising an insulating housing moulded from plastics material with a portion defining a cavity for receiving a connector adapted to mate with the pins which cavity has a base wall opposite a connector admitting mouth, the base wall being provided with an array of apertures, a plurality of mounting legs integrally formed with the cavity defining portion and having resilient latching portions at free ends for receipt in apertures in the circuit board to mount the header on one side of the circuit board with the pins extending through respective apertures into the cavity, characterised in that, the mounting legs (21) of the first header (12) are provided with longitudinally extending passageways (27) constituting sockets and the mounting legs (22) of the second header (13) are received in the sockets (27) to mount the second header (13) on the other side of the circuit board (9) with the pins (8) extending through respective apertures.

Claim 5

A header assembly according to claim 2, characterised in that, the base wall (18) of the second header is spaced apart from the circuit board (9) by engagement of the mounting legs (22) in the sockets (27).

Claim 6

A header assembly according to claim 1 or claim 2, characterised in that, the mounting legs (21,22) are bifurcated at their free ends.

Claim 7

A header assembly according to any one of claims 2 to 4, characterised in that, latching apertures (30) are provided in the cavity walls of each header (12,13).
