Abstract

So called cable retention features are often incorporated into printed circuit boards (PCB). These features ensure that an electric cable is held at a designated position on the PCB. Therefore, it eases assembly and protects the cable from any damage when forces are applied. Current solutions require the cables to be twisted into a retaining slot on each side of a “T”-shaped retention feature (see figure 1). This “T”-shaped retention feature is quite fragile and therefore easily broken. In consequence, brand new, populated and tested printed circuit boards are often thrown away because of missing or broken retention features. Furthermore, the outer heat shrink sleeve of a cable can be damaged easily due to sharp edges in the retention feature itself. Nowadays, there is no satisfactory solution ensuring that all PCBs exiting an assembly-line are unbroken.

Cable Retainer for Electric Cable

Idea: Glynn Roalf, UK-Congleton

So called cable retention features are often incorporated into printed circuit boards (PCB). These features ensure that an electric cable is held at a designated position on the PCB. Therefore, it eases assembly and protects the cable from any damage when forces are applied.

Current solutions require the cables to be twisted into a retaining slot on each side of a "T"-shaped retention feature (see figure 1). This "T"-shaped retention feature is quite fragile and therefore easily broken. In consequence, brand new, populated and tested printed circuit boards are often thrown away because of missing or broken retention features. Furthermore, the outer heat shrink sleeve of a cable can be damaged easily due to sharp edges in the retention feature itself. Nowadays, there is no satisfactory solution ensuring that all PCBs exiting an assembly-line are unbroken.

A novel solution to the problem mentioned above is presented in the following. A new design of a PCB retention feature is proposed, which is low curved in shape and robust enough to withstand assembly without breaking (see figure 2). The cut-out shape is capable of retaining and locking an electric cable on both sides without damaging its outer sleeve. The proposed retention feature also allows for a certain degree of feed-through aft...
