In order to make ammeter charged temporarily, all be to use two eradication edge leads to overlap in the past temporarily, a people holds lead overlap joint ammeter, and another people overlaps supply socket again, and this method is operated inconvenience and is had potential safety hazard.Use the insulated conductor of band plug to connect power supply afterwards, still had potential safety hazards such as electric shock, short circuit though can realize the one man operation.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of ammeter engaging means, uses simple, easy to operate, safety, can increase substantially work efficiency.
For this reason, the technical solution of the utility model is as follows:
A kind of ammeter engaging means, comprise housing and supply unit, travel switch and two contact electrodes of being installed on the described housing, described supply unit, described travel switch are connected with lead successively with described contact electrode, and described supply unit is used for described contact electrode is connected with external power source; Described travel switch is used for the switching of the described contact electrode of control; Described contact electrode is used for connecting described ammeter.
Described supply unit comprises plug, fuse and switch, and described fuse one end links to each other with described plug, and the other end links to each other with described switch, and the described switch other end connects described travel switch.Whether switch is used for control ammeter engaging means electricity, and then these ammeter engaging means are charged for Closing Switch during use, not then this ammeter engaging means outage of time spent cut-off switch.
Described ammeter engaging means also comprise the 1st, the 2nd pilot lamp, described the 1st, the 2nd pilot lamp is connected between described switch and the travel switch, when described switch closure and travel switch disconnection, described the 1st pilot lamp is lighted, when described switch and travel switch were closed simultaneously, the 2nd pilot lamp was lighted.
Distance between the described contact electrode is adjustable, and described housing is provided with the long lumbar hole of adjusting for described contact electrode position, and can fix described contact electrode.The ammeter engaging means that the contact electrode position is adjustable to provide the utility model are applicable to the ammeter of multiple different model.
Described plug is the earth leakage protective device plug, makes power connection safer.
Described the 1st, the 2nd pilot lamp is the LED lamp.
These ammeter engaging means are easy to operate, use safety, can connect ammeter quickly and easily, finish the modification of data in the ammeter.
Description of drawings
