1,038,520. Two-part couplings. AMP Inc. May 31, 1965 [June 8, 1964], No. 23002/65. Addition to 1,029,907. Heading H2E. A socket contact comprising two axially aligned spaced tubular portions 31 connected solely by spring contacts 30 extending helically about the axis of the tubular portions, as described in the parent Specification, is mounted in a housing 20 which has an aperture at the top in alignment with the openings at both ends of the socket contact and a wall 36 at the bottom which is pushed out when a pin is inserted so that the pin can pass completely through the contact and the housing. The wall 36 is present so that when the housing is dip soldered into position in a printed circuit board 10 the solder does not enter inside the housing. The wall 36 may be held to the housing 20 by a weakened portion 35 running all round the wall 36 or only partially round the wall so that the wall is not punched completely out by insertion of the pin but merely hinges on the unweakened side. In an alternative construction the wall 36 tapers to the middle where there is a pin-point aperture to form a starting point for opening up the wall (Fig. 5, not shown). A plurality of printed circuit panels may be stacked and the same pin member passed through a series of aligned socket members. |
