Description
Technical field
The present invention relates to universal switch technical fields, more particularly, to a kind of universal change-over switch with aviation plug.
Background technique
Universal change-over switch is composed of more contact heads.In the electrical apparatus, it is chiefly used in non-frequently connecting and disjunction
Circuit realizes changing-over power supply and load, can be used as circuit controling switch, test equipment switch, motor controling switch, can measure
Three-phase voltage and positive and negative rotation and the star delta starting etc. for controlling low capacity asynchronous motor are a kind of multi-gear type, control more times
The master control electrical apparatus on road.
Universal change-over switch is made of shaft, cam, contact shoe, positioning mechanism, Luo Gang and handle etc..Contact system is by counting
A moving contact being assembled in the intracorporal fixed contact pedestal of insulation shell and movable support is constituted.Moving contact is the touching of double breaking points dock
Bridge, in the shaft with handle, when handle turns to different stalls, shaft is rotated with it with cam, makes some contacts
It connects, other contacts disconnect, to realize the on/off function of circuit.Positioning mechanism uses idler wheel card ratchet structure, matches
Different locating parts is set, can get the switch of different stalls.
In control and measuring system, the conversion of circuit can be carried out using change-over switch.Such as electrical equipment power supply
Switch, the positive and negative rotation of motor is switched, and voltage, commutation of electric current etc. in circuit are measured.
Conversion handle is a kind of development of knife-like switch, and lower planes act when difference is knife-like switch operation, converts handle
It is then left and right plane movement, and the handle of multiple contact, multi gear position can be fabricated to.
In electric grid secondary system, universal change-over switch converts handle, bypass/this line passage generally as a distant place/on the spot
Switch handle, divide/close a floodgate switching handle, reclosing block/unlock switching handle to use.
With growth, the universal change-over switch component ageing of the operation time limit, handle rotation bite, contact contact are gradually appeared
Bad situation, it is often necessary to replace universal change-over switch, and universal change-over switch used at present directly from contact lug to
Terminal block, cable is more, and replacement is difficult, is primarily present following problems:
(1) since installation site narrow space, replacement step are complicated, line difficulty is disconnected, is more changed jobs time-consuming very long (at least
Need 1 hour), it needs to sequentially include the following steps: and 1) first fills in secondary measure list, record all terminals of universal change-over switch
Son number；2) universal change-over switch main body is removed from screen cabinet or terminal box, removes universal change-over switch wiring one by one；3) it will remove
Wiring be connected to new universal change-over switch one by one by secondary measure list, and universal change-over switch is installed to screen cabinet or terminal box
It is interior.
(2) replacement that has a power failure is needed, operations staff operates power failure, power transmission heavy workload, time-consuming very long (about needing 2 hours).
(3) power load is lost when having a power failure, economic loss is caused, influences customer electricity.
(4) cable for needing to disconnect is more, and operating personnel manually disconnects there are mis-wired, the unstable risk of wiring, may
It will cause switch malfunction, tripping.
Summary of the invention
The present invention is the existing technology for disconnecting line difficulty, replacement time-consuming when solving prior art replacement universal change-over switch
Defect provides a kind of universal change-over switch with aviation plug.
To realize the above goal of the invention, the technical solution adopted is that:
A kind of universal change-over switch with aviation plug, including universal change-over switch contact and aviation plug, the aviation
Plug includes the male connector and female of grafting, and universal change-over switch contact passes through the male terminal of secondary cable core wire and aviation plug
Securely connection.
When using universal change-over switch provided by the invention, the female terminal of aviation plug is made to pass through secondary cable first
Core wire is securely connected with terminal block terminal, and terminal block can be realized by the connection function of aviation plug and open with omnipotent conversion
Close being connected for contact.
Compared with prior art, the beneficial effects of the present invention are:
Universal change-over switch provided by the invention includes aviation plug, after installing and using, terminal block and omnipotent conversion
Switch is attached by the connection function of aviation plug, and when needing replacing universal change-over switch, only needing will be with aviation plug
The universal change-over switch integral replacing of male connector, does not need to disconnect secondary cable；The working time is effectively reduced, working efficiency is improved；
And the replacement that has a power failure is not needed, load loss can be effectively reduced, is increased economic efficiency, ensures society's electricity consumption, improves power supply reliability；
And aviation plug is designed using anti-mis-insertion, it is ensured that wiring is correct, prevents operating personnel's mis-wired risk.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the universal change-over switch with aviation plug.
Fig. 2 is the front schematic view of male connector.
Fig. 3 is the front schematic view of female.
Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；
Below in conjunction with drawings and examples, the present invention is further elaborated.
Embodiment 1
As shown in Figure 1, 2, 3, a kind of universal change-over switch with aviation plug, including universal change-over switch contact 1 and boat
Blind plug 2, the aviation plug 2 include the male connector 21 and female 22 of grafting, and universal change-over switch contact 1 passes through secondary cable core
Line is securely connect with 21 terminal of male connector of aviation plug 2.
When using universal change-over switch provided by the invention, first pass through 22 terminal of female of aviation plug 2 secondary
Cable core is securely connected with 3 terminal of terminal block, and terminal block 3 and ten thousand can be realized by the connection function of aviation plug 2
Energy change-over switch contact 1 is connected.
In the present embodiment, the universal change-over switch includes 8 contacts 1.
The present invention divides the line of universal change-over switch and terminal block 3 using aviation plug 2, in numerical order (1-1,2-
2,3-3,4-4,5-5,6-6,7-7,8-8) use secondary cable core wire by universal change-over switch contact 1 and 2 male connector 21 of aviation plug
Terminal securely connects, and similarly (1-1,2-2,3-3,4-4,5-5,6-6,7-7,8-8) will with secondary cable core wire in numerical order
3 terminal of terminal block is securely connect with 2 female of aviation plug, 22 terminal.
2 male connector 21 of aviation plug, female 22 are designed using anti-mis-insertion, effectively prevent mispluging wiring.Universal change-over switch goes out
