ELECTRICAL CONNECTION DEVICE WITH SPRING CONNECTION MEMBER WITH SMALL-SIZED ACTUATOR AND MULTIPOLAR CONNECTOR WITH CONTACT OF MULTIPLE SPRINGS

摘要

PROBLEM TO BE SOLVED: To provide a small-sized electrical connection device comprising a spring-type connection member including an actuator.SOLUTION: An electrical connection device 10 comprises an insulator 20 including parallel sheets 23 in a length direction. Each of the sheets accommodates a connection member 30 including a spring terminal 31 and an actuator pin 40 having a cam shape opposing a spring 32, and a spring terminal is opened/closed by sliding the actuator pin into the corresponding sheet. The spring is ring-shaped while including a curved lower part 34. A rear upward part 35 can be engaged with an upper part 36 including a slot 37 for accepting a cam-shaped protrusion of the actuator pin and at least one electrical conductor. In the actuator pin, a hollow sheet is provided which is partitioned by two lateral walls. In the state where the spring is warped outwards at a maximum, namely, in the state where the spring terminal is closed and there is no content, the hollow sheet accepts the upward leg 35 of the ring-shaped spring.
