In embodiment of the present utility model, also the first Spring clip 21 can be arranged on together with the first rubber binding ring 22 in each first spliced eye 121, the first Spring clip 21 and the common locking of the first rubber binding ring 22 are inserted in the PT terminal in the first spliced eye 121.In the same manner, the second Spring clip 31 and the second rubber binding ring 32 also can together be arranged in each second spliced eye 131, the second Spring clip 31 and the common locking of the second rubber binding ring 32 are inserted in the testing terminal in the second spliced eye 131.
Preferably, for can clearly being distinguished, testing crew is inserted in each PT terminal and the ground wire of the first spliced eye 121, and/or clearly recognize the each testing terminal and the ground wire that are inserted in the second spliced eye 131, on jack box 10, be provided with the identification mark of easy each terminal of identification.In embodiment of the present utility model, identification mark comprises alphabetic flag.Can, only on corresponding each the first spliced eye 121 sides, aperture or only on corresponding the second spliced eye 131 sides, aperture, different alphabetic flags be set, to help testing crew to recognize different alternate circuit.Also can with each the second spliced eye 131 sides, aperture, the different alphabetic flag of word be set correspondingly on each the first spliced eye 121 sides, aperture, thereby help testing crew to recognize the alternate circuit of not allowing simultaneously.Identification mark also can comprise colour code or Digital ID, or mixes the above-mentioned mark of use.
In conjunction with shown in Figure 3, preferably, be provided with first in the same side of jack box 10 and renovate 122 and second and renovate 132, renovate 122 and second first and renovate 132 joint and be provided with and renovate mount pad 14.First renovates 122 and second renovates 132 and can overturn around renovating mount pad 14 respectively, renovates 122 second operations of renovating 132 folding thereby complete first.First renovate 122 be opened after, experimenter can clearly observe the situation of assigning that plugs the PT terminal in the first spliced eye 121, adjusts in time the position of assigning of PT terminal, PT terminal is inserted correct.Meanwhile, whether the front interior that testing crew also can clearly be observed jack box 10 has fallen into foreign material, clears up in time foreign material, and normally carrying out of guarantee test, keeps cleaning in jack box 10.Similarly, when second renovate 132 be opened after, testing crew can clearly be observed the situation of assigning of the testing terminal that plugs in the second spliced eye 131, adjusts in time the position of assigning of testing terminal, testing terminal is inserted correct.Whether the rear side inside that testing crew also can clearly be observed jack box 10 has fallen into foreign material, clears up in time foreign material.
The mistaken collision preventing mistake dismantling device of terminal of the present utility model, also can be applicable in the maintenance process of general home circuit circuit.
After the line wires of household electricity is removed, owing to there is no stationary device fixed placement, but be often optionally placed in somewhere, so there is the danger of getting an electric shock concerning maintenance personal, also likely cause short circuit.Apply the mistaken collision preventing mistake dismantling device of terminal of the present utility model, but maintenance personal can only insert the wire terminal of pulling down the installation that is not also able to do in time and is placed on the first spliced eye 121 or only inserts and be placed in the second spliced eye 131.By the time, while needing certain circuit is installed, testing crew is pulled down wire terminal again and is installed in the mistaken collision preventing mistake dismantling device of terminal.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
1, this device has solved the problem that causes short circuit because touch by mistake, thereby has avoided the generation of electric power accident, has protected electric power facility, has avoided the loss that causes because of electric power accident, has also protected power test personnel's safety simultaneously.Facilitate experimenter to differentiate each terminal, prevent that experimenter from reinstalling mistiming and tear terminal open, the object that this just really reaches mistaken collision preventing of the present utility model tears terminal open by mistake pulling down each terminal.
2, this device makes to be removed that terminal more stably assigns in the first spliced eye, testing terminal more stably assigns in the second spliced eye.
3, first renovate, second renovate arrange and facilitate experimenter in process of the test, to observe the situation that the terminal in jack box assigns, contacts and be convenient to experimenter to clear up in time the foreign material in jack box, testing crew just can be cleared up jack box inside easily, keeps mistaken collision preventing the cleaning of dismantling device by mistake of terminal.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
