Description
Technical field
The utility model relates to a kind of Equipotential connector, particularly relates to a kind of high voltage converter control cables screen Equipotential connector.
Background technology
High voltage converter realizes energy-conservation object by regulating motor speed, be mainly used in electric power, mining industry, the blower fan in the fields such as cement, the transmission of pump class controls, along with the fast development of power electronics industry, the volume of high voltage converter is more and more less, power density improves gradually, equipment internal induction magnetic field intensity is also in enhancing, low-voltage is carried in equipment, the cable of the analog signals of small area analysis produces common mode disturbances, and affect the operation of power electronic device and system, the most effective means of this common mode disturbances is suppressed to be adopt shielded type cable and do equipotential link to screen, but it is large but to there is volume in Equipotential connector conventional at present, operating difficulties, the problems such as shield effectiveness is bad.
Summary of the invention
The utility model provides the Equipotential connector that a kind of volume is little, simple to operate, shield effectiveness is good, be mainly used in as high in high voltage converter constant power density, signal is various and the equipment that High-frequency Interference is large, raising equipment dependability and stability while enhance productivity.
In order to achieve the above object, the utility model realizes by the following technical solutions:
High voltage converter control cables screen Equipotential connector, comprises framework, tie down screw and locking shell fragment, and described tie down screw afterbody is connected with locking shell fragment through the screwed hole of frame roof, offers confession equipotential connection and run in the slotted eye passed through below framework.
Described locking shell fragment is riveted on tie down screw, can relatively rotate between the two.
Knob place, described tie down screw top outer round surface annular knurl, axle head plane establishes cross recess.
Described locking shell fragment is the elastomer of a steel plate roll-forming, and itself and cable contact surface are circular arc.
Compared with prior art, the beneficial effects of the utility model are:
1) volume is little, simple to operate, shield effectiveness is good;
2) can manually or electric locking, reliable lock, large with cable shield contact area, improve shield effectiveness and then improve system works stability;
3) install, dismantle flexibly and easily, can put according to any direction, as inversion, vertically-arranged etc., be applicable to the equipment such as the high high voltage converter of power density;
4) can be closed or open for the equipotential connection slotted eye passed through that runs in, be applicable to fixed installation respectively or interim and scrap build is installed and used.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1, it is using state schematic diagram of the present utility model, the utility model high voltage converter control cables screen Equipotential connector, comprise framework 3, tie down screw 1 and locking shell fragment 2, described tie down screw 1 afterbody is connected with locking shell fragment 2 through the screwed hole at framework 3 top, offers confession equipotential connection and run in 5 slotted eyes passed through 31 below framework 3.
Described locking shell fragment 2 is riveted on tie down screw 1, can relatively rotate between the two.
Knob place, described tie down screw 1 top outer round surface annular knurl 11, axle head plane establishes cross recess 12.Knob place outer round surface annular knurl 11 can play anti-skidding effect, uses when being applicable to manual locking.Cross recess 12 in axle head plane uses when being applicable to electric tool locking.
Described locking shell fragment 2 is the elastomer of a steel plate roll-forming, and itself and cable 4 contact surface are circular arc.Locking shell fragment 2 compresses cable 4 screen and forms good contact, has locking effect to tie down screw 1 simultaneously, makes it can not loosen when shaking.
Framework 3 is the U-shaped structure that steel plate pressing and bending is made, and can play the effect that carrying cable and equipotential connection run in.
Following examples are implemented under premised on technical solutions of the utility model, give detailed execution mode and concrete operating process, but protection range of the present utility model are not limited to following embodiment.In following embodiment, method therefor is conventional method if no special instructions.
[embodiment 1]
Seeing Fig. 2, is the scheme of installation of the present embodiment.Run in 5 slotted eyes passed through 31 for closed slotted eye for equipotential connection below framework 3, and be applicable to fixed mounting means, once mounting can be many cables and provides equipotential link, convenient and swift.
During installation, first according to 1. direction equipotential connection run in and 5 to penetrate in slotted eye 31, then penetrate cable 4 according to 2. direction, rotate tie down screw 1 and make locking shell fragment 2 compress cable 4 screen.
[embodiment 2]
Seeing Fig. 3, is the scheme of installation of the present embodiment.Run in 5 slotted eyes passed through 31 for open slotted eye for equipotential connection below framework 3, and be applicable to portable mounting means, namely device context transforms use temporarily or forever, and need not dismantle any equipment can directly install.
During installation, first according to 1. direction, the slotted eye 31 below framework 3 is sleeved on equipotential connection at opening part and runs on 5, then penetrate cable 4 according to 2. direction, rotate tie down screw 1 and make locking shell fragment 2 compress cable 4 screen.
