Further, the crocodile clip includes the first jig arm and the second jig arm of switching, and the end of the first jig arm is set There is the inserted sheet towards the extension of the second jig arm direction.
Further, the end of first jig arm protrudes from the end of the second jig arm, first jig arm and the second folder Under the mutual clamped condition of arm, the inserted sheet is located at the outside of the second jig arm.
Further, the inserted sheet is provided with the escape groove for the screw rod that electric screw is connect described in correspondence.
Further, first jig arm is provided with the limited block relative with inserted sheet, it is described connect electric screw nut it is spacing Between inserted sheet and limited block.
Further, the conductor wire group includes the copper cash being embedded in vasculum.
Further, the vasculum side is provided with the interface to match with the joint of the stress_responsive genes, the copper cash One end extend to the interface.
Further, the other end of the copper cash connects the crocodile clip by cable.
Further, the cable includes cable core and the tension insulating barrier being coated on outside cable core, and the cable core and tension are exhausted Traction-resistant fibre layer is provided between edge layer.
Further, the bottom of the vasculum is provided with magnet.
Beneficial effects of the present invention:
The stress_responsive genes instrument of the present invention, add vasculum and carry out transition, vasculum one end connection stress_responsive genes instrument, adopt The header other end connects electrical terminals by crocodile clip, reduces the length of wire, so as to reduce the heavy burden of crocodile clip, enhancing connection Stabilization, reduce security risk;And vasculum can prevent conductor wire group from mutually winding, often connecting a stress_responsive genes instrument can save 5-10 minutes are saved, lift the reliability of wiring.
The present invention these features and advantage will be detailed in following embodiment, accompanying drawing exposure.
【Brief description of the drawings】
The present invention is described further below in conjunction with the accompanying drawings:
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 another scheme of installation of crocodile clip in invention.
【Embodiment】
The technical scheme of the embodiment of the present invention is explained and illustrated with reference to the accompanying drawing of the embodiment of the present invention, but under It is only the preferred embodiments of the present invention to state embodiment, and not all.Based on the embodiment in embodiment, people in the art Member obtains other embodiments on the premise of creative work is not made, and belongs to protection scope of the present invention.
With reference to figure 1, a kind of shown stress_responsive genes instrument, including stress_responsive genes instrument, stress_responsive genes instrument are connected by vasculum 1 Electric screw is connect, is provided with some conductor wire groups in vasculum 1 side by side, conductor wire group one end connects stress_responsive genes instrument, and conductor wire group is another One end connects electric screw by crocodile clip.The reliability of wiring is lifted by the setting, reduces security risk.
With reference to figure 2, crocodile clip includes the first jig arm 31 and the second jig arm 32, and the end of the first jig arm 31 in the present invention Provided with the inserted sheet 33 extended towards the direction of the second jig arm 32, when crocodile clip connects electric screw 4, inserted sheet 33 can be pressed on and connect electric spiral shell Between the nut and installation pedestal 5 of nail 4, or it is pressed between packing ring 6 and installation pedestal 5, then by the first jig arm 31 and second Jig arm 32 clamps and connects electric screw 4, difficult for drop-off so as to which crocodile clip be securely fixed with connecing electric screw 4.
The end of wherein the first jig arm 31 protrudes from the end of the second jig arm 32, and the first jig arm 31 and the second jig arm 32 are mutual Under clamped condition, inserted sheet 33 is located at the outside of the second jig arm 32.Inserted sheet 33 will not be to the second jig arm 32 rotation produce interference, the One jig arm 31 and the second jig arm 32, which relative can clamp, connects electric screw 4.
The escape groove 331 of the corresponding screw rod 41 for connecing electric screw is provided with inserted sheet 33, therefore inserted sheet 33 may pass through and connect electric spiral shell The screw rod 41 of nail, the area being pressed between the nut for connecing electric screw 4 and installation pedestal 5 can increase so that compress relatively reliable.
With reference to figure 3, crocodile clip from connect electric screw 4 it is laterally-clamped when, inserted sheet 33 can not extend into the nut for connecing electric screw 4 Between installation pedestal 5, therefore the limited block 34 relative with inserted sheet 33, the first jig arm 31 and second are provided with the first jig arm 31 The clamping plate 35 of jig arm 32 is located at the both sides of limited block 34, and the opposite face of clamping plate 35 sets clip tooth, connect electric screw 4 nut it is spacing Between inserted sheet 33 and limited block 34.The clip tooth of clamping plate 35 provides normal pressure and screw is engaged, then coordinates the He of inserted sheet 33 Spacing, the fixation of limited block 34, the movement and rotation of crocodile clip can be effectively limited, ensure the stability of installation, be not easy Come off.
Preferably, conductor wire group includes the copper cash 21 being embedded in vasculum 1.The side of vasculum 1 is provided with and stress_responsive genes The interface 11 that matches of joint, one end of copper cash 21 extends to interface 11, and the other end of copper cash 21 extends to the another of vasculum 1 Side, and crocodile clip is connected by cable 22.Under the structure, avoid producing interference between adjacent conductor wire group, formed overall Chunk, it is easy for installation.
Due to crocodile clip and electric mode connects for screw stabilization is connect, external force, which surprisingly pulls down, may cause cable 22 to damage, therefore this The cable 22 of invention includes cable core and the tension insulating barrier being coated on outside cable core, is also provided between cable core and tension insulating barrier Traction-resistant fibre layer.To strengthen its tensile capacity, extend service life.
Slim magnet can be provided with the bottom of vasculum, on the ironware of firm absorption in the work environment;Replace or It is to be provided with the plastic cement projection corresponding with the arrangement of conductor wire group side by side in the bottom of vasculum, plastic cement projection can play anti-skidding With the effect of damping, and cable can be wrapped in plastic cement projection, avoid mutually winding between a plurality of cable.
