Junctor, and connect with external equipment by connector and pass to external equipment.
Preferably, each described electric signal transmission mechanism includes:
Conductive strips, described conductive strips one end connect the brush, and the other end connects the conductive component being arranged on connector,
It is connect by the conductive component with external equipment, so that the electric signal of brush is passed to external equipment；The conductive strips table
Face is additionally provided with felt pad, for being dielectrically separated to conductive strips.
Preferably, the conductive component is 2 bolts.2 bolts be separately connected one described in conductive strips, and by conductive strips
On signal pass to external equipment connected to it, so that the electric signal of brush is passed to external equipment.
Compared with prior art, beneficial effects of the present invention:
The brush connecting plate is connected by using elastic component, thus control connect with the brush connecting plate it is automatic right
Brush in middle mechanism keeps good with conducting ring and contacts, meanwhile, and brush was unlikely to by the pressure of elastic component
A large amount of abrasion is generated greatly, to increase the service life of brush, shorten maintenance time.Pass through the flexible of elastic component
Performance is eliminated to be vibrated caused by external impact force, makes the reliable contacts between brush and conducting ring, realizes brush assembly of electric oneself
Dynamic vibration damping；
Meanwhile in the automatic centering mechanism, brush connect the hinge arrangement to be formed using pin with fixed block, so that
Brush can be rotated around pin, reliably be contacted so that brush be made to remain under the pressure of elastic component with conducting ring, and connect
Contacting surface product is maximum, realizes automatic centering of the brush to conducting ring.
