A high-stability miniature circuit breaker has a pivotal shaft having a first section, a second section and a shoulder. The diameter of the second section is larger than the first section. The shoulder diameter is larger than the second section. A pivoting lever on the first section limits the axial position of a protruding mesa relative to the shaft by contact fit between the mesa and a thrust surface on the second section. A pivoting latch is on the second section. A first end face fits to a support surface on the shoulder. A second end face fits to the protruding mesa at the other end. The latch controls a drive rod and the lever. A connecting rod separates from the latch when latch hasps are separated and the latch separates from the drive rod which slides along a groove of the lever.

Minitype breaker with high stability

A circuit breaker includes a housing, wiring boards and terminals disposed within the housing, wherein the terminal comprises a screw, a press board and a wire trap provided with a incoming line hole and a wiring space; the screw passes through a threaded hole on the top end face of the wire trap to contact the press board which is able to lift up and down and is embedded in the wire trap; the wiring board traverses the wire trap, and divides the wiring space of the wire trap into two independent wiring spaces; a first line hole is provided on the housing at a position above the screw of the terminal; and the press board and the wire trap perform a relative displacement with the wiring board under the action of the screw, to compress the two independent wiring spaces so as to realize the connection between wires. In the circuit breaker, with the wiring board as a boundary, the wiring space of the wire trap is divided into two independent wiring spaces, realizing a hybrid junction of commonly used wires while realizing the hybrid junction wiring function of single-strand wires with different diameter.

A handle locking device for a modularized terminal electric appliance is presented. A housing base thereof can be assembled onto any outer side surface of the housing of an appliance through a connection mechanism. There are a horizontal pivoting door and a vertical pivoting door which can be unfolded or folded inside a door hole on a sliding member of the locking mechanism. When unfolded, the horizontal pivoting door mates with an appliance handle to block the reverse motion of the handle, and the vertical pivoting door and the horizontal pivoting door can mate to block the reverse motion of the unfolded horizontal pivoting door. The horizontal pivoting door is pivotally connected to the sliding member through a horizontal pivoting, and the vertical pivoting door is pivotally connected to the sliding member through a vertical pivoting. A padlock is provided with a lock ring which can penetrate the interconnected door hole from a padlock hole and the lock ring can mate with the vertical pivoting door to block the reverse motion of the unfolded vertical pivoting door. The locking mechanism is connected and mounted with the housing base through a moving pair and can only perform up/down sliding along the direction of an assembly reference line B parallel to the appliance height direction Y, the locking mechanism is defined to slide merely between the locking and unlocking positions thereof, and adjustable height position of the locking device under the two states of handle locking and unlocking is realized by way of the shift of the sliding member.
