Insulation cover plate extends to after having buckle closure be dielectrically separated from parts between two conductive components, and this isolated part makes to lead
Connected components is irremovable to turning on the position of two conductive components, and insulation cover plate offers with to test terminals relative
Resigning hole.
Further, described insulation crust both sides are respectively arranged with the first fastener of evagination, described insulation cover plate
Bottom, two ends is respectively arranged with the second fastener can being fastened on the first fastener, described insulation cover plate by first,
The second detachable buckle closure of fastener is at described insulation crust top.
Further, described insulation cover plate two ends are respectively arranged with operating handle, by executing two operating handles
Add power in opposite directions and make described insulation cover plate deformation, so that described first, second fastener is mutually disengaged.
Further, the gap between described isolated part and described two conductive components matches.
Further, described second fastener has the hook portion that can hook described first fastener.
Further, described insulation cover plate, isolated part, the second fastener and operating handle integrated injection molding.
Further, described calibrating terminal is the cylindric through hole that one end is connected with described conductive component.
This utility model realizes also by techniques below scheme:
A kind of prototype version terminal, two conductive components including insulation crust, being disposed in insulation crust,
Can conducting with disconnect connecting assembly, being separately positioned on the upside of two conductive components of movement between two conductive components
Test terminals, also include protective cover as above.
This utility model has the advantages that
1, between the isolated part of this utility model protective cover can be inserted between prototype version terminal two conductive component
In gap, stop that the assembly that connects of prototype version terminal moves, the test loop at thorough open test type terminal place,
Avoid the phenomenon that secondary lateral primary side reverse charge occurs in process of the test.
2, the protective cover that this test is novel can fully wrapped around live prototype version terminal exposed metal part,
Eliminate the hidden danger that testing crew gets an electric shock in wiring accidentally.
3, all parts integrated injection moldings of this utility model protective cover, by applying in opposite directions operating handle
Power make insulation cover plate deformation so that the second fastener opens, install or dismantle the most very convenient.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described in further details.
Fig. 1 is the structural representation of existing prototype version terminal.
Fig. 2 is the structural representation of this utility model protective cover.
Fig. 3 is the schematic top plan view of this utility model protective cover.
Fig. 4 is the use state diagram of this utility model protective cover.
Detailed description of the invention
As it is shown in figure 1, existing prototype version terminal include insulation crust 1, be disposed in insulation crust 1 two
Conductive component 2, can conducting with disconnect connecting assembly 3, being separately positioned on two of movement between two conductive components
Test terminals 4, the first fastener 5 of evagination on the upside of conductive component 2, test terminals 4 are one end and conduction
The cylindric through hole that parts 2 connect, connects the conductive component 2 on assembly 3 and the right when disconnecting, two conductive components 2
Disconnecting, connect assembly 3 and can move right to the conductive component 2 with the right and contact, now two conductive components 2 turn on.
As shown in Figures 2 to 4, include can the buckle closure insulation cover plate at insulation crust 1 top for protective cover of the present utility model
6, insulation cover plate 6 extends to the isolated part 7 of the insulation between two conductive components 2, this isolation after having buckle closure
Gap between parts 7 and two conductive components 2 matches, and makes to connect assembly 3 irremovable to conducting two conductive parts
The position of part, insulation cover plate 6 offers the resigning hole 8 relative with testing terminals 4, can pass through at the trial
P-wire is connected by resigning hole 8 with test terminals 4, and bottom, insulation cover plate 6 two ends is respectively arranged with and can be fastened on
The second fastener 9 on first fastener 5, insulation cover plate 6 is existed by the first detachable buckle closure of fastener the 5, second fastener 9
Insulation crust 1 top, the second fastener 9 has the hook portion 91 that can hook the first fastener 5, and insulation cover plate 6 two ends are divided
Not being provided with operating handle 10, making insulation cover plate 6 deformation by operating handle 10 being applied power in opposite directions, thus
