Background technology
Along with the widespread use of consumer, also more and more higher to the security requirement of consumer, consumer has the plug of access civil power usually, in use, plug does not access civil power often polarity, and therefore, consumer plug does not just become extremely important by polarity restriction.In the prior art, the dipole inversion function of test consumer, the method usually adopted directly is transferred to from socket by plug, then plug turned polarity and reinsert socket, test.There is following problem in this test mode: one, dials and insert very loaded down with trivial details, because the dipole inversion test of consumer often needs to exchange repeatedly, this with regard to the plug needing tester and carry out repeatedly is; One, poor stability, owing to there will be abnormal problem after the exchange of some consumer polarity, such as, generate heat, burn, even explode, and therefore, just there is larger security risk when dialling plug; Three, because the polarity test of consumer often needs more than one piece consumer to test simultaneously, therefore, dial the test mode of the slotting formula reverse of polarity, be difficult to the synchronism detection of more than one piece consumer.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of socket test bench with polarity reversing switch is provided, this socket test bench can make the polarity test process operation of consumer convenient, fast, and test process security is high, the synchronism detection of more than one piece consumer can be completed.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of socket test bench with polarity reversing switch, comprise insulation box body, insulation box body is provided with power input plug, polarity reversing switch, on-off switch and at least two power output sockets; First electrode of described power input plug, after the first fuse, is electrically connected with the first moving contact of polarity reversing switch, and the second electrode of described power input plug, after the second fuse, is electrically connected with the second moving contact of polarity reversing switch; First stationary contact and the 4th stationary contact of described polarity reversing switch are electrically connected, and the first stationary contact and the 4th stationary contact are after on-off switch, are electrically connected with the first electrode of power output socket; Second stationary contact and the 3rd stationary contact of described polarity reversing switch are electrically connected, and the second stationary contact and the 3rd stationary contact are after on-off switch, are electrically connected with the second electrode of power output socket; First moving contact and the second moving contact phase interlock of described polarity reversing switch, the first moving contact and the first stationary contact, the corresponding cooperation of the second stationary contact, the second moving contact and the 3rd stationary contact, the corresponding cooperation of the 4th stationary contact.
Described first fuse and the second fuse are rewirable fuse, and these two rewirable fuses are from being screwed into outside insulation box body to the circuit of insulation box body.
Described insulation box body comprises upper casing and lower casing, and this upper casing and lower casing are screwed connection.
Described insulation box body is provided with eight power output sockets.
The beneficial effects of the utility model are: one, the utility model, by pressing polarity reversing switch, can realize the polarity of electrode conversion of power output socket, operation is very easy, quick; Two, the utility model is provided with the first fuse, the second fuse and on-off switch, decreases the abnormal problem occurred in test to greatest extent, thus makes security very high, tests more reliable; Three, the utility model, is provided with at least two power output sockets, and thus once can complete the synchronism detection of more than one piece consumer, test result is more accurate.
