3.1 modular connector
adapter used in lower limb prosthetic assembly
3.2 convex connector
connecting part of the modular adapter with an inverted pyramid
3.3 concave connector
receiving part of the modular adapter with a pyramid receiver
4 Geometrical aspects of mating connectors (adapters)
4.1 General
Concave: Pyramid receiver
Convex: Pyramid connector
If a modular connector is used as an adjustable connector between prosthetic components, weaknesses of the connection can occur if the contact area of the convex and concave surfaces does not establish the largest possible diameter.
5 Risk evaluation and testing
Components manufactured according to this document shall be in accordance with ISO 22523.
The samples constructed for testing to ISO 10328 and ISO 22675 using the modular systems shall be utilized with the dimensions of these interfaces.BS ISO 24562 pdf download.
