Electrical male connector - has contact pins provided with transverse bores into which insulating block mould material penetrates to prevent pin rotation

摘要

The electrical male connector has one or more brass contact pins (2) moulded into a block (1) of rigid or semi-rigid insulating material such as rubber or plastic. The pins are cylindrical and at one end have respective holes in which connector cables are clamped by screws (4) coaxial with the pins. Rotation of the screws can cause rotation of the oins and this is prevented by provision of one or more transverse bores (6) in the pins into which the block material penetrates during moulding. Alternatively, blind bores interconnected by a surface acid groove may be provided to secure the pins against axial and turning movements. The former may be restricted in addition by block collars moulded about reduced dia. portions of the pins projecting from the block.
