SHV Jacks (Female) Guide: Types, Structure, and Uses Explained
What Are SHV Jacks (Female)?
SHV Jack Connectors (Female) are Safe High Voltage coaxial connectors designed for high-voltage signal connections with a recessed contact and insulated structure to reduce exposure to energized conductors. They use a bayonet coupling mechanism for secure locking and are not compatible with BNC or MHV connector types. Tyclon’s SHV jack connectors support rated alternating current voltage up to 3.5 kV, high insulation resistance, and low contact resistance, making them suitable for measurement, research, and high-voltage equipment applications.
Although SHV connectors share visual similarities with BNC interfaces, they are intentionally not mechanically compatible. Tyclon’s SHV jack connectors are manufactured with Japanese precision to support stable impedance characteristics and dependable electrical performance in high-voltage systems.
Mating of SHV Connectors
SHV jacks are designed with a recessed insulator and a bayonet coupling mechanism.
- After insertion, a slight twist securely locks the connector in place.
- The locked state can be confirmed by tactile feedback.
- The design helps prevent incomplete or improper mating.
SHV jacks are intended for use exclusively with SHV plugs (male).
They are not compatible with BNC or MHV plugs.
SHV Jacks (Female) by Type
SHV jack connectors feature a female interface for safe high-voltage connections and are typically mounted to panels or equipment housings. In the Tyclon SHV connector series, jack configurations are available in straight designs, engineered to provide secure mating, stable electrical performance, and dependable operation in high-voltage RF applications.
Trivia: Jacks vs. Receptacles
SHV Plugs and Jacks are engineered for specific coaxial cable types (e.g., RG-58/U) to ensure reliable insulation and operational safety under high voltage.
In contrast, Receptacles are primarily designed for panel-mounted applications. They provide flexibility for internal wiring, as they can be connected to various high-voltage wires provided the conductor diameter is compatible with the center contact for soldering.
However, since a receptacle does not secure the cable’s outer jacket (sheath), its mechanical retention is limited. For this reason, receptacles are most commonly used for internal wiring within an enclosure or chassis where the cable is protected from external stress.
To minimize the risk of accidental contact with energized parts, SHV receptacles standardly feature a female interface, ensuring that high-voltage contacts remain recessed. Additionally, we offer plug receptacles with a male interface for applications that require this configuration.
SHV Jacks (Female) Cable Installation Guide
SHV jacks (female) are used for safe high-voltage cable termination and are installed at the end of a coaxial cable for connection to an SHV plug (male). To ensure stable electrical performance and a high level of safety, Tyclon SHV jack connectors specify soldering for the center contact and mechanical tightening of the connector body.
1. Connection of the Center Contact and the Conductor
The cable inner conductor (core wire) is soldered to the center contact using an appropriate temperature-controlled soldering iron and suitable solder. This method provides consistent electrical contact, maintains controlled impedance, and ensures reliable insulation for high-voltage operation. Avoid overheating the dielectric or creating cold joints; after soldering, inspect the joint for full wetting and alignment.
2. Connection of the Connector Body and the Outer Shield
The connector body is secured by tightening the main body with a wrench to the specified torque. Ensure that the cable’s outer shield (braid) and jacket are correctly seated according to the connector design so the shield achieves full circumferential contact with the designated clamping or contact surfaces inside the connector. Proper mechanical tightening provides effective grounding, robust mechanical strength, and long-term reliability under high-voltage conditions. Use a calibrated torque tool and avoid over-tightening.
3. Cable Compatibility Check
SHV jacks must be selected according to the specified cable type and diameter. Using an incompatible cable may result in degraded electrical performance or compromised safety. For detailed information on compatible cables, materials, plating, and attachment specifications, please refer to the Material / Plating / Attachment section on each product page.
