A header assembly includes an insulating block having a given thickness and a plurality of pin-receiving passages therethrough. A plurality of terminal pins are received in the passages and project from the insulator block for insertion into holes in a printed circuit board and for solder connection to circuit traces on the circuit board. The terminal pins are interference-fit in the passages in the insulator block to allow the block to be slid off the pins after soldering to the printed circuit board. The area of the inference-fit between the terminal pins and the pin-receiving passages is less than the thickness of the insulator block to reduce the amount of force required to slide the block off of the pins while affording the block to be of a substantial thickness. The pin-receiving passages are provided with chamfered mouths to facilitate insertion of terminal pins into the passages. A flange projects outwardly from the top of the insulator block to facilitate gripping the block and sliding the block off the terminal pins.

A slip-off header assembly for temporarily retaining terminals pins in a predetermined array therein until said pins are secured to a printed circuit board, said header assembly including an insulator block having a given generally uniform thickness and a plurality of pin-receiving passages therethrough, a plurality of terminal pins received in the passages and having end portions projecting from the insulator block for insertion into holes in a printed circuit board and for solder connection to circuit traces on the board, the terminal pins being interference-fit in the passages in the insulator block to allow the block to be slid off the pins after soldering to the printed circuit board, wherein the improvement comprises said given thickness of said insulator block being sufficient so that said block is relatively stiff to maintain the end portions of the terminal pins in said predetermined array and the length of the interference-fit between the terminal pins and the pin-receiving passages being equal to or less than one half the thickness of the insulator block to reduce the amount of force required to slide the block off the pins while affording the block to be of a substantial thickness.
