Further, described inserted sheet be provided with connect described in correspondence electric screw screw rod dodge groove.
Further, described the first jig arm is provided with the limited block relative with inserted sheet, described in to connect the nut of electric screw spacing between inserted sheet and limited block.
Further, described conductor wire group comprises the copper cash being embedded in vasculum.
Further, described vasculum one side is provided with the interface that the joint with the test of described harmonic wave matches, and one end of described copper cash extends to described interface.
Further, the other end of described copper cash connects described crocodile clip by cable.
Further, described cable comprises cable core and is coated on the tension insulation course outside cable core, between described cable core and tension insulation course, is provided with traction-resistant fibre layer.
Further, the bottom of described vasculum is provided with magnet.
Beneficial effect of the present invention:
Harmonic wave testing tool of the present invention, has increased vasculum and has carried out transition, and vasculum one end connects harmonic wave tester, the vasculum other end connects power connection end by crocodile clip, reduces the length of wire, thereby reduces the heavy burden of crocodile clip, strengthen connect stable, reduce security risk; And vasculum can prevent that conductor wire group is wound around mutually, harmonic wave tester of every connection can be saved 5-10 minute, promotes the reliability of wiring.
These features of the present invention and advantage will be below embodiment, accompanying drawing in detailed exposure.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is the structural representation of vasculum;
Fig. 2 is a kind of scheme of installation of crocodile clip in invention;
Fig. 3 is the another kind of scheme of installation of crocodile clip in invention.
[embodiment]
Accompanying drawing below in conjunction with the embodiment of the present invention is explained and illustrated the technical scheme of the embodiment of the present invention, but following embodiment is only the preferred embodiments of the present invention, not all.Embodiment based in embodiment, those skilled in the art are other embodiment that obtains under the prerequisite of not making creative work, all belongs to protection scope of the present invention.
With reference to figure 1, shown in a kind of harmonic wave testing tool, comprise harmonic wave tester, harmonic wave tester connects electric screw by vasculum 1, in vasculum 1, be provided with side by side some conductor wire groups, conductor wire group one end connects harmonic wave tester, and the conductor wire group other end is connected and connect electric screw by crocodile clip.By this, reliability that promotes wiring is set, reduces security risk.
With reference to figure 2, in the present invention, crocodile clip comprises the first jig arm 31 and the second jig arm 32, and the end of the first jig arm 31 is provided with the inserted sheet 33 extending towards the second jig arm 32 directions, when crocodile clip connects electric screw 4, inserted sheet 33 can be pressed between the nut and mounting base 5 that connects electric screw 4, or be pressed between packing ring 6 and mounting base 5, then clamp and connect electric screw 4 by the first jig arm 31 and the second jig arm 32, thereby crocodile clip is firmly fixed to difficult drop-off with connecing electric screw 4.
Wherein the end nipple of the first jig arm 31 is for the end of the second jig arm 32, and under the first jig arm 31 and the mutual clamped condition of the second jig arm 32, inserted sheet 33 is positioned at the outside of the second jig arm 32.Inserted sheet 33 can not produce and interfere the rotation of the second jig arm 32, and the first jig arm 31 can relatively clamp and connect electric screw 4 with the second jig arm 32.
On inserted sheet 33, be provided with correspondence connect electric screw screw rod 41 dodge groove 331, so inserted sheet 33 can be through the screw rod 41 that connects electric screw, is pressed on to connect the nut of electric screw 4 and the area between mounting base 5 can increase, and makes to compress more reliable.
With reference to figure 3, when crocodile clip clamps from connecing the side direction of electric screw 4, inserted sheet 33 cannot extend between the nut and mounting base 5 that connects electric screw 4, therefore in the first jig arm 31, be provided with the limited block 34 relative with inserted sheet 33, the clamping plate 35 of the first jig arm 31 and the second jig arm 32 are positioned at the both sides of limited block 34, the opposite face of clamping plate 35 arranges clip tooth, and the nut that connects electric screw 4 is spacing between inserted sheet 33 and limited block 34.The clip tooth of clamping plate 35 provides normal pressure to carry out interlock to screw, then coordinates spacing, the fixation of inserted sheet 33 and limited block 34, can effectively limit movement and the rotation of crocodile clip, guarantees the stability of installation, difficult drop-off.
Preferably, conductor wire group comprises the copper cash 21 being embedded in vasculum 1.Vasculum 1 one sides are provided with the interface 11 that the joint with harmonic wave test matches, and one end of copper cash 21 extends to interface 11, and copper cash 21 other ends extend to the opposite side of vasculum 1, and connect crocodile clips by cable 22.Under this structure, avoid producing and disturbing between adjacent conductor wire group, form whole chunk, easy for installation.
Due to crocodile clip with connect electric screw stable connection, under external force surprisingly pulls, may cause cable 22 to damage, therefore cable 22 of the present invention comprises cable core and is coated on the tension insulation course outside cable core, also between cable core and tension insulation course, is provided with traction-resistant fibre layer.To strengthen its resistance to tension, extend serviceable life.
Can be provided with in the bottom of vasculum slim magnet, on the firm ironware being adsorbed in working environment; That replace or in the bottom of vasculum, be provided with side by side the plastic cement projection corresponding with arranging of conductor wire group, plastic cement projection can play anti-skidding and effect damping, and cable can be wrapped in plastic cement projection, avoids being mutually wound around between many cables.
By above-described embodiment, object of the present invention is by fully effective having reached.The personage who is familiar with this technology should be understood that the content that the present invention includes but be not limited to accompanying drawing and describe in embodiment above.Any modification that does not depart from function and structure principle of the present invention all will be included in the scope of claims.
