Abstract

A lamp socket and panel mount assembly for a printed circuit board includes a lamp socket having a bulb opening at one end thereof with terminal means therein for electrical connection to a bulb and with the terminal means including radially outwardly directed tab portions for electrical connection to leads of a printed circuit board when the housing is supported on a mounting panel; the housing includes locator and stop surfaces thereon to permit insertion thereof from either side of the printed circuit board and mounting panel into a fixed axial relationship with the panel wherein rotation of the housing with respect to the panel electrically connects the tab portions to circuit board leads and positions locator and stop surfaces on the housing to secure it and a flexible printed circuit board to the mounting panel.

Claims

1. A printed circuit bulb socket and panel mounting assembly for connecting a bulb socket to a circuit board from either side of the board comprising:

a mounting board having a circular opening with radially outer guide slots defining arcuately located index surfaces thereon, a socket housing having an outer surface for insertion through said circular opening, a first pair of locater means on said housing extending axially at only one end thereof, a second pair of locater means on the housing extending axially at only the opposite end thereof, stop surfaces formed on said first pair of axial locater means, stop surfaces formed on said second pair of axial locater means, said first pair of locater means being located in axially guided engagement with the index surfaces when said housing is inserted from one side of the board, said stop surfaces on said second pairs of locater means being engageable with the board to limit axial insertion of the housing from the one side of the board and to locate the housing for rotation with respect to the board to a locked position where the board is held between said first and second pairs of locater means, said second pair of locater means being locatable in alignment with said guide slots for axially guided insertion of the housing from the opposite side of the board with said stop surfaces on said first pair of locater means locating the housing for rotation into the aforesaid locked position with the board held between said first and second pair of locater means, terminals on said housing located in electrical contact with said board when said housing is in its rotatably locked position, said first and second pair of locater means and the stop surfaces thereon preventing movement of the housing totally through said hole upon insertion of the housing from opposite sides thereof.

2. A printed circuit bulb socket and panel mounting assembly for connecting a bulb socket to a circuit board from either side of the board comprising:

a mounting board having a circular opening with radially outer guide slots defining arcuately located index surfaces thereon, a socket housing having an outer surface for insertion through said circular opening, a first pair of locater lugs on said housing extending axially at only one end thereof, a second pair of locater lugs on the housing extending axially at only the opposite end thereof, a pair of longitudinal ribs on said housing at a point arcuately spaced from said second pair of locater lugs, stop surfaces formed on said first pair of axial locater lugs, stop surfaces formed on said second pair of axial locater lugs, said first pair of locater lugs located in axially guide engagement with the index surfaces when said housing is inserted from one side of the board, said stop surfaces on said second pairs of locater lugs being engageable with the board to limit axial insertion of the housing from the one side of the board and to locate the housing for rotation with respect to the board to a locked position where the board is held between said first and second pairs of locater lugs, said second pair of locater lugs and said longitudinal ribs being locatable in alignment with said guide slots for axially guided insertion of the housing from the opposite side of the board with said stop surfaces on said first pair of locater lugs locating the housing for rotation into the aforesaid locked position with the board held between said first and second pair of lugs, terminals on said housing located in electrical contact with said board when said housing is in its rotatably locked position, said first and second pair of locater lugs and the stop surfaces thereon preventing movement of the housing totally through said hole upon insertion of the housing from opposite sides thereof.

3. A printed circuit bulb socket and panel mounting assembly for connecting a bulb socket to a circuit board from either side of the board comprising:

A mounting board having a circular opening with radially outer guide slots defining arcuately located index surfaces thereon, a socket housing having an outer surface for insertion through said circular opening, a first pair of axial locater lug means on said housing extending axially at only one end thereof, a second separate pair of axial locater lug means on the housing extending axially at only the opposite end thereof and including a rib segment, stop surfaces formed on said first pair of axial locater lug means, stop surfaces formed on said second pair of axial locater lug means, said first pair of locater lug means located in axially guided engagement with the index surfaces when said housing is inserted from one side of the board, said stop surfaces on said second pairs of locater lug means being engageable with the board to limit axial insertion of the housing from the one side of the board, said first pair of lug means having inclined surfaces thereon engageable with said index surfaces to draw the stop surfaces on the second pair of lug means with respect to the board upon rotation of said socket housing, coacting surfaces on said rib segments and said index surfaces positioning said socket housing at a locked position where the board is held between said first and second pairs of locater lug means, said second pair of locater lug means being locatable in alignment with said guide slots for axially guided insertion of the housing from the opposite side of the board with said stop surfaces on said first pair of locater lug means locating the housing for rotation into the aforesaid locked position with the board held between said first and second pair of lug means, terminals on said housing including ear portions supported on said stop surfaces formed on said second pair of axial locater lug means to be located in electrical contact with said board when said housing is in its locked position, said first and second pair of locater lug means and the stop surfaces thereon preventing movement of the housing totally through said hole upon insertion of the housing from opposite sides thereof.
