Detailed Description

The embodiments of the utility model will be further described with reference to the accompanying drawings in which:

as shown in the figure, the electric connection structure of the circuit breaker comprises a shell 1, a rotating base 2 rotatably installed in the shell 1, a contact pin installation base 3 in transmission fit with the rotating base 2 and a circuit board 4 fixedly arranged in the shell 1, wherein a contact pin 31 is arranged on the contact pin installation base 3, a socket corresponding to the contact pin 31 is arranged on the circuit board 4, and the rotating base 2 has a first state that the contact pin 31 is driven to extend out of the shell 1 when rotating clockwise and a second state that the contact pin 31 is driven to retract into the shell 1 when rotating anticlockwise; according to the technical scheme, the rotating seat is rotated, when the rotating seat rotates clockwise, the contact pin extends forwards, and otherwise, the contact pin retracts backwards; when the structure is applied to a working environment in which a plurality of circuit breaker modules are connected with each other, the contact pin can extend out and be inserted into the socket of the front circuit breaker only by clockwise rotating the rotating seat, so that effective electric connection is realized, otherwise, the contact pin retracts into the circuit breaker to break the electric connection, and the circuit breaker is in an initial position;

The roating seat 2 by the center plate 21, with the concentric knob dish 22 that sets up of center plate 21 and with the eccentric disc 23 of the eccentric setting of center plate 21 constitute, the knob dish 22 sets up at the 21 upper surfaces of center plate and stretches out shell 1, eccentric disc 23 sets up at the 21 lower surface of center plate, the knob dish sets up a word groove, can rotate through a word screwdriver, the knob dish rotates, drives the center plate and rotates, drives the eccentric center that coils the center plate moreover and rotates.

The socket sets up side by side and has preceding socket 42 and back socket 43 of jack 41 including the front and back, preceding socket is the electricity with the back socket and is connected on the circuit board, and when the shell was stretched out to the contact pin front end, the contact pin rear end was extracted from the jack of back socket, but the contact pin rear end still in the socket in the front, just so can guarantee the electricity of each circuit breaker and connect, is equipped with two sockets on the circuit breaker module, can realize the electricity of circuit breaker module and be connected, just can realize the connection and the control of a plurality of functional module.

The quantity of shell 1 is a plurality of and hugs closely side by side in proper order, roating seat 2 clockwise rotation drives back socket 43 in the preceding shell 1 is inserted to contact pin 31, 2 anticlockwise rotations drives contact pin 31 extracts from the back socket 43 in the preceding shell 1.

The contact pin mount pad 3 is equipped with the rolling groove 32 with eccentric disc 23 roll complex in the position that lies in contact pin 31 top, the rolling groove is waist shape hole, the contact pin mount pad is only front and back linear motion in the shell, and it is through setting up the rolling groove that is waist type hole, removes the displacement volume that removes about with the eccentric disc, only keeps the displacement volume of seesaw.
