Abstract

Hollow cylindrically shaped conductive (e.g., BeCu) retention clips 1 (Fig. 1), having inwardly disposed opposing spring tabs 2, are molded in a plastic pinless header, i.e., a protective shroud 3 (Fig. 2) to simplify assembly of the shroud 3 onto the input/output (I/O) pins (not shown), extending outwardly from a printed circuit (PC) board (not shown) or the like. By way of example, shroud 3 has ten pin openings 4, which are configured in a 5 x 2 rectangular array. For the sake of clarity, only two of its corresponding ten clips 1 are shown in Fig. 2. In operation, the open end associated with the lower face 5 of shroud 3 is positioned over the compatible array of I/O pins (not shown) which are to be protected by shroud 3 and are located on the PC board (not shown).

Self-Retaining I/O Pin Shroud

Hollow cylindrically shaped conductive (e.g., BeCu) retention clips 1 (Fig. 1), having inwardly disposed opposing spring tabs 2, are molded in a plastic pinless header, i.e., a protective shroud 3 (Fig. 2) to simplify assembly of the shroud 3 onto the input/output (I/O) pins (not shown), extending outwardly from a printed circuit (PC) board (not shown) or the like. By way of example, shroud 3 has ten pin openings 4, which are configured in a 5 x 2 rectangular array. For the sake of clarity, only two of its corresponding ten clips 1 are shown in Fig. 2. In operation, the open end associated with the lower face 5 of shroud 3 is positioned over the compatible array of I/O pins (not shown) which are to be protected by shroud 3 and are located on the PC board (not shown). As the shroud 3 is being downwardly installed, each I/O pin (not shown) enters its associated aligned respective opening 4 and passes through the central opening of the particular clip 1 that is molded in the respective opening 4. With face 5 in contact with the surface (not shown) of the board (not shown) header 3 is retained assembled,
i.e., held to the board by the resultant locking action of the tab springs 2 against the I/O pins (not shown) mounted to the board. As such, the assembly is ready to receive the compatible female receptacle (not shown) which is plugged into the I/O pins (not shown) through the upper open end associated with the upper face 6 of shroud 3,...
