Came up with some connectors in a style I'm not familiar with, and cannot find a reference that shows how they should be assembled.
These are a "clamp" style connector for RG8/LMR400 size cables. I've put together plenty of clamp style connectors, but none with this type of components. Here are the parts, but unknown if this is the correct order of assembly or direction: 
Center pin is captivated in that white insulator. I think I have it figured out (the parts order in the photo), but it's bugging me that I can't find a reference to be sure. Arfcom can answer any question, right? |

Arfcom can answer any question, right? I can't even tell if it's UHF or N, so I'm no help at all! How does the center attach to the conductor? It's UHF, center pin just solders on. I'm trying to figure out how the clamping part for the shield is supposed to work. |

Is it anything like any of these?
Specifically like on page 39. http://www.arrl.org/files/file/Technology/tis/info/pdf/9105034.pdf |

Gamma, I think the hat shaped clamp turns the other way so as to compress the gasket.
Or maybe the braid solders to the hat shaped bushing? IDK, I'd have to try to put one together. I know,  the braid fans out past the smaller ID washer and is clamped against the 'hat'.

The orientation of the "hat" is correct, cut back the outer jacket, fan out the braid and press the "hat' down the center dielectric with the small diamater end going under the braid. |

The braid gets folded back over the 'hat' shaped insert so that it contacts the outer housing. All the parts are oriented correctly in the picture. |

All the parts are oriented correctly in the picture. The braid won't fit through the "hat". Center insulator will though. I think that washer goes over the braid, the braid is folded back and then the "hat" slides over the insulator down into the cable and the folded over braid gets clamped between the washer and the hat. |

Something similar: http://www.eyou.com.au/upload_files/How_assemble_clamp_N.pdf |

That's essentially what I had envisioned, except that my connector has an additional washer which I was figuring went on the front side of the rubber washer. |

That's what it looks like to me, and usually I see metal-metal contact clamps rather than metal-nonmetal clamps so I'd say the washers go in that order. Your dielectric and inner conductor should fit nicely inside the hat-shaped piece and a braided outer conductor would slip over it. Of course the tighter the fit between the dielectric and the less you perturb the outer conductor the smaller discontinuity you'll have so everything should be pretty snug. |

That's what it looks like to me. I don't know what the second washer is for, but it looks like exactly this. Your dielectric and inner conductor should fit nicely inside the hat-shaped piece and a braided outer conductor would slip over it. Of course the tighter the fit between the dielectric and the less you perturb the outer conductor the smaller discontinuity you'll have so everything should be pretty snug. Is that red piece an elastic or maybe soft plastic? I'd imagine it serves to retain the connector screw clamp. The red piece is a rubber material, it gets squished and forms a weather seal once the connector is assembled. |
