ABSTRACT:
To permit economical attachment of a socket end to the press of a lamp, the socket is made of a deformable synthetic plastic material, for example Teflon PFA, the socket having concentric cylindrical surfaces and being of cup shape, and the lamp press having rectangular cross section, the socket being heated to softening temperature and the lamp press to melting temperature of the socket material and then inserted into the cup-shaped socket to permit instantaneous melting andflowing of the socket material around the edges of the rectangular press, and thus seat the socket on the press end. The socket is preferably preheated in a metal mold block, and the press by a flame directed towards the end press of the lamp from a side remote from that of the electrical connection to the lead-through of the press.
