1. A wind turbine blade, comprising:
- an upper shell member having a spar cap configured on an internal face thereof;
a lower shell member having a spar cap configured on an internal face thereof;
a shear web extending between said spar caps along a longitudinal length of said blade, said shear web having opposite transverse ends;
a connection assembly between at least one of said transverse ends of said shear web and a respective said spar cap, said connection assembly further comprising;
a spacer member configured on said spar cap, said spacer member having a transverse engagement face; and
a male/female engagement interface between said transverse end of said shear web and said spacer member defined by a male member within a female recess;
wherein said male/female engagement interface comprises an axial extension length to accommodate for shear web length variances; and
a transverse width engagement section between said transverse end of said shear web and said transverse engagement face of said spacer member on each opposite side of said male/female engagement interface.

Abstract
A wind turbine blade has upper and lower shell members with a respective spar cap configured on an internal face of the shell members. A shear web extends between the spar caps along a longitudinal length of the blade. A connection assembly is configured between the transverse ends of the shear web and the spar caps. The connection assembly includes a spacer member configured on the spar cap. A male/female engagement interface is defined between transverse end of the shear web and the spacer member, and includes an axial extension length to accommodate for variances in shear web length.
