Electronic modular package having a printed circuit assembly

Claim 2

An electronic modular package having a printed circuit assembly comprising: a hard circuit board having first and second terminal blocks secured thereto adjacent the opposite ends thereof respectively, said first terminal block having a width less than that of the end portion of said circuit board to which it is secured, said second terminal block having a width greater than the width of said first terminal block and slightly greater than the maximum width of said circuit board. a rigid plastic, hollow elongated housing of generally rectangular cross section having a larger opening at one end and a smaller opening at an opposite end, said circuit board being disposed in said housing by sliding said circuit board with said first and second terminal blocks secured thereto into said housing through said larger opening first terminal block first until said first terminal block is disposed in said smaller opening and said second terminal block is disposed in said larger opening. latch means comprising cooperative portions of said first terminal block and portions of said housing adjacent said smaller aperture for securing said circuit boards within said housing, said latch means constituting the sole means preventing withdrawal of said circuit board whereby said circuit board is substantially isolated from forces associated with pushing a mating connector onto said first terminal block, and stop means comprising cooperative portions of said second terminal block and said housing adjacent said larger opening for limiting insertion of said circuit board into said housing, said stop means constituting the sole means limiting insertion of said circuit board into said housing whereby said circuit boaRd is substantially isolated from forces associated with pushing a mating connector onto said second terminal block.

Claim 3

An electronic modular package having a printed circuit assembly comprising: a hard circuit board having an electrical circuit printed on a top surface thereof and a plurality of electrical components located below said circuit board and secured thereto by tab terminals extending through said circuit board with protruding end portions soldered to said printed circuit, first and second terminal blocks secured to said circuit board adjacent the opposite ends thereof respectively, said first terminal block having a width less than that of the end portion of said circuit board to which it is secured, said second terminal block having a width greater than the width of said first terminal block and slightly greater than the maximum width of said circuit boards, a rigid plastic, hollow elongated housing of generally rectangular cross section having a larger opening at one end, a smaller opening at an opposite end, a ceiling with side rails and a generally planar floor uninterrupted by protrusions, said circuit board being disposed in said housing by sliding said circuit board with said first and second terminal blocks secured thereto into said housing through said larger opening first end first until said first terminal block is disposed in said smaller opening and said second terminal block is disposed in said larger opening, said first and second terminal blocks supporting said circuit board and spacing said plurality of electrical components secured thereto from said floor, said side rails overlying the longitudinal edge portions of said circuit board and being of sufficient height to prevent the protruding ends of said tab terminals from engaging said ceiling, latch means comprising interlocked ramped portions of said first terminal block and said housing adjacent said smaller aperture for securing said circuit board within said housing, said latch means constituting the sole means preventing withdrawal of said circuit board whereby said circuit board is substantially isolated from forces associated with pushing a mating connector onto said first terminal block, stop means comprising triangularly arranged cooperative portions of said second terminal block and said housing adjacent said larger opening for limiting insertion of said circuit board into said housing, said stop means constituting the sole means limiting insertion of said circuit board whereby said circuit board is substantially isolated from forces associated with pushing a mating connector onto said second terminal block, and means for mounting said housing on a support member, said means including an integral dome atop said housing and a deflectable latch arm forming an integral part of said dome.

Claim 4

An electronic modular package having a printed circuit assembly comprising: a hard circuit board having an electrical circuit printed on a top surface thereof and a plurality of electrical components located below said circuit board and secured thereto by tab terminals extending through said circuit board with protruding end portions soldered to said printed circuit, first and second terminal blocks secured to said circuit board adjacent the opposite ends thereof respectively, said first terminal block having a width less than that of the end portion of said circuit board to which it is secured, said second terminal block having a width greater than the width of said first terminal block and slightly greater than the maximum width of said circuit boards, a rigid plastic, hollow elongated housing of generally rectangular cross section having a larger opening at one end, a smaller opening at an opposite end, a ceiling with side rails and a generally planar floor uninterrupted by protrusions, said circuit board being disposed in said housing by sliding said circuit board with said first and second terminal blocks secured thereto into said housing through said larger opening first end first until said first terminal block is disposed in said smaller opening and said second terminal block is disposed in said larger opening, said first and second terminal blocks supporting said circuit board and spacing said plurality of electrical components secured thereto from said floor, said side rails overlying the longitudinal edge portions of said circuit board and being of sufficient height to prevent the protruding ends of said tab terminals from engaging said ceiling, latch means comprising interlocked ramped portions of said first terminal block and said housing adjacent said smaller aperture for securing said circuit board within said housing, said latch means constituting the sole means preventing withdrawal of said circuit board whereby said circuit board is substantially isolated from forces associated with pushing a mating connector onto said first terminal block, stop means comprising triangularly arranged cooperative portions of said second terminal block and said housing adjacent said larger opening for limiting insertion of said circuit board into said housing, said stop means constituting the sole means limiting insertion of said circuit board whereby said circuit board is substantially isolated from forces associated with pushing a mating connector onto said second terminal block, and means for mounting said housing on a support member, said means including an integral dome atop said housing and a deflectable latch arm forming an integral part of said dome.
