Flashcards: BNC Crimp Connector Assembly — 30 cards

For which cable is the Telegärtner G1 BNC male connector designed?

RG-58C/U cable with 4.95 mm outer diameter.

What is the characteristic impedance of the Telegärtner G1 BNC male connector?

50 Ω.

How many pieces make up the connector?

Three pieces.

Name one piece of the connector.

BNC male body.

What does crimp/crimp termination do?

Crimps both the centre pin and the braid ferrule without soldering.

Is soldering used in crimp/crimp termination?

No, soldering is not used.

Under which die reference is the connector specified?

100025879.

What instruction specifies the connector?

T00100A0200 (A0205).

What is the compatible cable type with 4.95 mm diameter and 50 Ω impedance?

RG-58C/U cable.

Which cables are included in the compatibility group with RG-58C/U?

YR23092, LMR-195, and RG-58.

What tool is preferred for cable preparation?

A three-blade adjustable coax stripper.

What type of die is required for crimping?

An XM-type die with reference 100025879.

What are the sizes of the HEX cavities in the crimping die?

1.72 mm and 5.41 mm.

What tools are required for inspection?

A magnifier and a multimeter.

What does the multimeter verify during inspection?

That continuity between conductor and braid is open.

What is the total strip length from jacket end to conductor tip?

18 mm

From which point is the dielectric length measured?

From the conductor tip

What is the dielectric length measured from the conductor tip?

10 mm

How long must the centre conductor be exposed?

5 mm

To which cables does the 7 mm stripping value apply?

Double-foil cables only

Why does the 7 mm stripping value not apply to RG-58C/U?

Because it has a single braid, not an outer foil

Why must the specified strip lengths be followed exactly?

They govern the 50 Ω impedance match and return loss

What is the first step in the assembly sequence?

Sliding on the ferrule.

What must be done after stripping the jacket in assembly?

Folding back the braid.

What is the final step in the assembly sequence?

Crimping the ferrule.

How must the centre conductor be positioned after crimping?

Flush with the centre-pin tip.

What is forbidden after ferrule crimping regarding braid strands?

No braid strand may protrude.

Why must no braid strand touch the conductor?

Because a short circuit corrupts the Acoustic Emission signal.

Why must the braid crimp be uniform?

To prevent noise and false hits in Acoustic Emission measurements.

What checks are done before commissioning for reproducible tests?

Verify conductor continuity, shield isolation, and cable length.
