Detailed description of the invention
With specific embodiment, protection contact of the present utility model performeter is made the most below in conjunction with the accompanying drawings
Describe, but not as to restriction of the present utility model.
As depicted in figs. 1 and 2, this utility model provides a kind of protection contact performeter, including battery 1, relay
Device, display lamp 2 and binding post, the positive pole of battery 1 is connected conducting with relay coil 4, relay include relay coil 4 with
Normally opened contact 5, relay coil 4 and normally opened contact 5 relay in series self-holding circuit, when normally opened contact 5 closed action
After, relay self-holding circuit keeps path.
Display lamp 2 is arranged at relay self-holding circuit for indicating loop break-make, when relay self-holding circuit is logical
Lu Shi, shinny after display lamp 2 is charged.
Binding post includes internal current conductor and the external insulation being made of copper, overall in cylindrical structural.Terminals
Son constitutes monitoring circuit with battery 1 and relay coil 4, and it includes the first binding post 8 being connected respectively with protection contact 10
With the second binding post 9, when protection contact 10 closes, monitoring circuit conduction band motor type relay action is so that relay self-sustaining is returned
Road turns on.When after the closed action of protection contact 10, with the first binding post 8 and the second binding post 9 protecting contact 10 to be connected
Being turned on by monitoring circuit, battery 1 powers to relay coil 4, and after relay coil 4 is charged, produced magnetic force drives normally opened touching
Point 5 Guan Bi, display lamp 2 is charged shinny, even if after protection contact 10 returns (disconnection), relay coil 4 is by normally opened contact 5
Can keep charged, thus constitute relay self-holding circuit, display lamp 2 continues shinny.
It is provided with one by compressing switch 6 in monitoring circuit, by arranging spring by compressing switch in 6, it is possible to realize pressure and press
Compressing switch after 6, it can recover to rebound automatically.Depressing by compressing switch after 6, relay coil 4 dead electricity, normally opened contact 5 disconnects, all
Loop is no longer turned on, and display lamp 2 goes out.By compress switch 6 automatically rebound after, protection contact performeter reverts to original state,
Such that it is able to monitor next time.Wherein, 6 it is made up of plastic material by compressing switch.
Being additionally provided with a current-limiting resistance 7 in relay self-holding circuit, current-limiting resistance 7 is connected with display lamp 2, prevents instruction
Lamp 2 burns out in the case of electric current is excessive.
Battery 1, relay and current-limiting resistance 7 are arranged in housing 3, and housing 3 is square box shape.Open on the one side of housing 3
Being provided with hole, battery 1 puts into housing 3 by hole, and battery cover 11 is connected to cover battery 1 by the way of hinged and leads to housing 3
The hole crossed.Binding post, display lamp 2 and 6 be arranged on the another side of housing 3 by compressing switch, binding post passes through test wire
Being connected with protection contact 10, the internal current conductor of binding post matches with the plug of test wire；Bright by viewing lamp 2
Go out situation, the action situation of protection contact 10 can be monitored；By pressure by compressing switch 6, can recover to protect contact action prison
The original state of visual organ, thus monitor next time.
Above example is only exemplary embodiment of the present utility model, is not used in restriction this utility model, and this practicality is new
The protection domain of type is defined by the claims.Those skilled in the art can be at essence of the present utility model and protection domain
In, this utility model is made various amendment or equivalent, this amendment or equivalent also should be regarded as in this practicality new
In the protection domain of type.
