Description
Technical field
The present invention relates to a kind of circuit breaker movable conductor syndeton.
Background technology
Contact of breaker is to carry out circuit breaker to realize the key that supply line cut-offs, and the connected mode of existing circuit breaker and leading-out terminal is normally coupled together both the connecting plate of contact root and leading-out terminal realize (as shown in Figure 1) in loop by the mode of welding by the copper litz wire of soft state.Because the connecting plate of breaker outgoing line end is fixed, and contact of breaker is to need motion, and both must connect with the medium of soft state just can not affect the contact motion.
Although yet said structure can realize that loop connects, but because copper litz wire is that the copper wire tiny by diameter worked out, combine and can leave gap between rear copper wire, and weld has lump, and the copper wire that diameter is tiny extremely easily causes a little appearance broken string, can affect circuit breaker when serious and cause phase fault or cause electric accident.
On the other hand, because the field of employment of circuit breaker is more and more wider, the product of miniaturisation high-performance more and more is subject to market favor, and the connected mode of using copper litz wire to connect contact and connecting plate can cause the circuit breaker volume can be larger.
Summary of the invention
In order to overcome in existing contact of breaker and connecting plate connected mode, adopt the appearance broken string that easily causes because the copper litz wire diameter is tiny existed to cause that short circuit, electric accident and this connected mode make the volume of circuit breaker own very much not be easy for the shortcoming of miniaturization product, the invention provides a kind of circuit breaker small volume, production process reduces, contact of breaker is connected with connecting plate and does not affect again the circuit breaker movable conductor syndeton of the connected mode of contact of breaker rotation.
The technical solution used in the present invention is:
Circuit breaker movable conductor syndeton, it is characterized in that: comprise touch spring, left touch spring supporter, gear shaft, left connecting plate, locking spring, left-hand rotation moving contact, right connecting plate, locking spring lid, contact rotation axis, right touch spring supporter, rotating shaft and right-hand rotation moving contact, described gear shaft is also fixed riveted joint with described left-hand rotation moving contact and right-hand rotation moving contact respectively through the rotational axis hole be arranged on left touch spring supporter and right touch spring supporter respectively, and rotatable between the two after riveted joint, described left-hand rotation moving contact and right-hand rotation moving contact are symmetrical arranged, and the left-hand rotation moving contact is close in the notch inboard on described left connecting plate, and the right-hand rotation moving contact is close in the notch inboard on described right connecting plate, the outside of described left and right connecting plate is connected with described locking spring one end, the other end of described locking spring is provided with described locking spring lid, and described left and right connecting plate and the described large I that turns left and right the contact resistance between contact are adjusted by the moment size of described locking spring, described rotating shaft is provided with rotation axis " U " shape notch, described contact rotation axis covers through the locking spring in left side successively, the locking spring in left side, left connecting plate, the left-hand rotation moving contact, left touch spring supporter, right touch spring supporter, the right-hand rotation moving contact, right connecting plate, the locking spring on right side and the locking spring on right side lid and its two ends, left and right are connected with described rotating shaft respectively and are arranged in described rotation axis " U " shape notch, be provided with described touch spring between described rotating shaft and left touch spring supporter and between described rotating shaft and right touch spring supporter.

Further, be provided with axis hole on the described centre that turns left and right the left and right sides of the afterbody of contact, described left and right connecting plate, described locking spring lid and described left and right touch spring supporter and axis hole described above is concentric circles, pass for described contact rotation axis.
Further, the described axis hole that turns left and right the afterbody of contact arranges with one heart, but by described contact rotation axis by above-mentioned both connect and independently movings, guarantee the effective contact area of contact.
Beneficial effect of the present invention is embodied in:
1, this circuit breaker provided by the invention rotates the hard conductor connection of contact, owing to having adopted, connecting plate is connected by the mode of locking spring with the rotation contact, and contact resistance can be adjusted by the moment size of locking spring, therefore has good electric conductivity.And after adopting hard conductor to connect, the electric conductor coupling part takes up room and can obviously dwindle, and do not worry having the disconnected burst phenomenon of copper litz wire and cause phase fault or puncture.
2, this circuit breaker provided by the invention rotates the hard conductor connection of contact, owing to rotating contact and connecting plate, adopt two of left and right to connect separately, and touch spring and touch spring supporter also support separately a side and rotate contact, in the situation that contact-making surface is not that about very parallel can the assurance, two contacts have an even contact point, guarantee the reliability of product.
