Molex makes a line of connectors for similar applications called BMI (Blind Mate Interface). They have a self aligning feature that is perfect for this. Here are a few examples. 3 is probably the best IMO. Link 1 Link 2 Link 3 |

I recall Ken Layton pointing out that Molex connectors had a limited life span, so they were probably not the best option for connectors that would be frequently cycled. While I can't find Ken's post, I do note the following from Marvin3M, which reinforces what Franco says (and may be his source for the 25 use life cycle): --- Quote ---The style of Panduit and Molex connectors used in pinball generally have a 25 "cycle" life span (a "cycle" is one removal and re-installation of a connector). And frankly, after as few as five cycles, there could be problems because of the high vibration pinball environment, the reduced terminal pin tension, and the age of many games. --- End quote --- http://marvin3m.com/connect/index.htm#worn :cheers: EDIT: Other posts since I start writing this, but I think it still holds to the point ... EDIT2: I've been looking at the BMI spec, but can't seem to find a reference to cycle life span (other than "high"). |

What is a 'solder cup'? Not sure I've see that or know what it is? --- End quote --- Soldering wires into a DB connector is the easiest thing you can do. You slide the wire into a little tube and fill it with solder. |

As you know, many people refer to the plugs commonly found in arcade cabs as molex plugs. I have a Molex catalog that is 1 1/2" thick, 90% of it is their connector lines. I am sure the reason he said that they were not meant to be cycled over and over is due to the lack of a strain relief system. Without it, the wires would break near the crimp rather soon from the constant pulling. |
