Description
Technical field
The present invention relates to low-voltage electrical switch technical field, more particularly to a kind of sound contact structure and rotary switch.
Background technology
Rotary switch may include multiple layers, and every layer includes a running contact and multiple stationary contacts, many for switching simultaneously
Individual electric current.Electrical rotary switch is mainly used in switching direct current.Spark can be also produced when alternating current is cut off in electric current non-zero.
Spark generates the explosion like heat plasma cloud of usually corrosivity and conduction, and plasma cloud or spark plume are so as to damage
Neighbouring object and/or generation cause short circuit, and spark and its influence increase with the increase of power switched.
At present, the sound contact structure of every layer of rotary switch for electrical equipment generally comprises shell, and the middle part of shell includes one
Space for installing running contact component, the surrounding in the space is uniformly distributed the installation position for being provided with four stationary contacts；Wherein,
Running contact component includes current-carrying part and insulated part, and current-carrying part is symmetrical arranged and is located along the same line, and conductive part divides it
It is outward insulated part, on four installation positions of shell, selects one group of diagonal installation position for setting to be respectively mounted stationary contact, stationary contact
Point includes the contact portion for being contacted with running contact and the coupling part for connecting wire, two contact portion skew symmetries
It is located along the same line.When running contact component turns to two current-carrying parts to be in contact with two contact portions respectively, rotation
Turn contact to be connected with stationary contact.
But, conventional sound contact structure has the following disadvantages：
1st, in order to improve security, reduce object near electric arc or electric spark damage, cause the situations such as short circuit, on housing
The arc quenching plate of metal is installed, electric arc or electric spark can be absorbed/cool down by arc quenching plate, generally, arc quenching plate is installed outside
On position between the installation position of shell and running contact component.But, because two stationary contacts are diagonal setting, therefore, housing
On have been provided with can not being set again at the installation position of stationary contact arc quenching plate (the contact portion influence of stationary contact), only two are not pacified
Arc quenching plate can be installed at the installation position for filling stationary contact.This kind of mounting means, can cause arc quenching plate to absorb running contact component
Electric arc or electric spark produced by one rotation direction, for example, the absorbable running contact component of arc quenching plate is rotationally clockwise
When the electric arc or electric spark that produce, electric arc or electric spark can be applied on arc quenching plate in tangential direction, and then absorbed by arc quenching plate/
Cooling, but, when running contact component is rotated counterclockwise, electric arc or electric spark because the absorption/cooling without arc quenching plate, then
It is applied directly on housing, the potential safety hazard for existing in such cases is larger, does not have the protection of arc quenching plate, electric arc can ablation sound
Contact and plastic casing and substantially reduce the service life of rotary switch；
2nd, two stationary contact diagonally opposing corners are set, and the same diagonally opposing corner of contact portion of corresponding two stationary contacts is set, this kind of
Set-up mode can cause contact portion nearer near housing side, and when using, the probability of contact arc or electric spark is higher, equally
There is potential safety hazard, influence the service life of rotary switch；
3rd, in the sandwich construction of rotary switch, generally, one layer of stationary contact is that the diagonally opposing corner in a direction sets
Put, two in next Rotating fields stationary contact is then set using the diagonally opposing corner in another direction.Using this kind of mounting means easily
There is the situation of assembly defect, cause running contact to be contacted with stationary contact, and waste time and energy, and then cause rotary switch not
Can normally use.
