DELOCK SMB plug 91786 for crimping RG-174 and RG-316 with heat-shrink tubing

DELOCK SMB plug 91786 for crimping RG-174 and RG-316 with heat-shrink tubing is a crimp-style SMB connector kit engineered for terminating small-diameter coaxial cables. The kit contains the connector body, crimp ferrule and insulating parts with heat-shrink tubing to provide reliable electrical contact, mechanical strain relief and moisture-resistant insulation. It is suited for on-site cable termination, repair and small RF link installations where a compact SMB interface is required.

Advantages

The crimp design ensures a consistent mechanical and electrical connection without soldering, reducing assembly time and supporting repeatable results. Heat-shrink tubing included in the kit improves environmental protection and secures the cable-to-connector transition against mechanical stress. The compact SMB form factor provides a small footprint for use in tight spaces while maintaining proper impedance matching for RF signals on RG-174 and RG-316 cables.

How to use

Prepare the coaxial cable by stripping the outer jacket, dielectric and exposing the center conductor following the connector manufacturer’s recommended strip dimensions. Slide the heat-shrink tubing and crimp ferrule onto the cable, insert the cable into the connector body ensuring the center conductor seats in the pin and the braid makes good contact with the outer contact. Crimp the ferrule with an appropriately sized crimp tool for the selected cable type, verify mechanical retention and electrical continuity, then apply heat to the tubing to shrink and secure the insulation and strain relief. Inspect the assembled connector for proper seating and ensure the assembled SMB plug mates smoothly with the intended socket.

Recommendations

Use the correct crimp die sized for RG-174 or RG-316 to achieve a reliable connection; verify continuity and return loss where applicable. Avoid excessive heat when shrinking to prevent damage to dielectric materials. For repeated or critical RF installations, test the assembled connection with a suitable RF tester to confirm signal integrity.
