FSV / FSD Pre-Insulating Convex Fork Terminal
YOCL ELECTRIC FSV / FSD Pre-Insulating Convex Fork Terminal combines two crimp styles in one series: FSV single-crimp and FSD double-crimp. Copper fork contacts with PVC sleeves are listed in red, blue and yellow groups for 0.5–6 mm² conductors.
- 29 paired specification rows with both FSV and FSD model codes.
- Select by conductor range, bolt-hole diameter and fork width.
- Model-level B, F and L dimensions and group-level A, E, D1 and D2 dimensions are provided.
Overview
YOCL ELECTRIC FSV / FSD Pre-Insulating Convex Fork Terminal combines FSV single-crimp and FSD double-crimp insulated fork styles in one product series. The copper open-fork contact is intended for a compatible bolted terminal, while the PVC sleeve covers the conductor-side connection. The catalog lists 29 paired size rows across red, blue and yellow groups for 0.5–6 mm² conductors.
Features
- Two crimp styles: FSV is the single-crimp version and FSD is the double-crimp version, listed side by side for each size row.
- Convex fork contact: the open fork is shaped for a suitable bolt or stud connection.
- Copper and PVC construction: the catalog identifies copper terminal material and a PVC insulating sleeve.
- Three colour groups: red, blue and yellow identify different conductor ranges and maximum current values.
- Size-specific fit: metric bolt-hole diameter, US bolt designation and B, F and L dimensions are listed for each paired model row.

Dimension
The table and source drawings label the fork and barrel dimensions B, F, L, A, E, D1 and D2. The source also gives a metric bolt-hole diameter d2 and a separate US bolt designation. All numeric dimension values are millimeters.

A, E, D1 and D2 apply by colour group as shown above. The source prints FSV 1.25-3.5 and FSD 1.25-3.5 twice with the same hole diameter but different B widths (5.7 and 6.4 mm); both specification rows are preserved.
Selection Guide
Choose the conductor range and FSV or FSD crimp style, then match the bolt or stud to the hole diameter d2. Check B, F and L for fork fit and installation space. For the duplicated 1.25-3.5 codes, state the required B width when requesting a quotation.
