  • Structure of electrical connecting device
    Patent number: 4468075
    Abstract: An electrical connecting device where electrical terminals are connected between two connector units by inserting the first connector unit into an insertion mouth of the second connector unit. Moreover, the electrical terminals of both units come into pressure contact by inserting the first connector unit into the second connector unit and then rotating the first connector unit in the direction almost at a right angle to the inserting direction. Such a structure is highly adaptable to an electrical connecting device where the first connector unit comprises a magnetic bubble memory unit, while the second connector unit comprises a holder unit for accommodating the bubble memory unit. This device realizes a stable and reliable electrical connection between both units with an excellent operability for insertion.
