Ficha de crimpagem para conector fêmea SMA coaxial DELOCK 91785 para RG-174/RG-316 com tubo termorretrátil

DELOCK 91785 is an SMA female crimp connector designed for terminating RG-174 and RG-316 coaxial cables. The connector offers a compact SMA female interface for RF signal connections and is supplied with a heat-shrink sleeve to provide strain relief and environmental protection. It is intended for creating or repairing small-diameter coaxial assemblies where stable electrical contact and a low-profile RF connection are required.

Advantages

The crimp attachment method ensures a mechanically secure and electrically consistent connection, reducing the risk of intermittent contact compared with solder-only terminations. The included heat-shrink sleeve improves mechanical strain relief at the cable exit and provides additional protection against moisture and abrasion. The compact SMA female geometry supports common RF test and measurement setups and fits in tight spaces typical of communication devices and instrumentation.

Key specifications

How to use

Strip the RG-174 or RG-316 cable according to the connector’s required conductor, dielectric, and braid lengths. Slide the heat-shrink sleeve and the ferrule onto the cable, insert the prepared cable into the connector body so that the center conductor seats in the contact and the braid is captured under the ferrule. Crimp the ferrule with a suitable crimp tool sized for the connector and cable. Inspect the mechanical and electrical connection and apply heat to the heat-shrink sleeve to secure strain relief and finish the assembly.

Recommendations

Use the correct crimp die for the specified cable to achieve reliable mechanical and RF performance. Verify continuity and return loss where applicable after assembly. Do not overstrip the dielectric or deform the center conductor; follow standard coaxial assembly practices to maintain impedance and minimize signal reflections.
