On be formed with any mounting groove unit；Mounting groove unit includes multiple for fixing the mounting groove of cable to be installed, the installation
Slot is arranged in parallel and inner surface is in circular arc planar；The center of adjacent fitting grooves is located at two sides away from the diameter for being less than cable to be installed
Mounting groove meet: cable to be installed be more than half be partially submerged into the mounting groove, and the opening width of mounting groove be less than to
The diameter of cable is installed.
Since cable to be installed can be partially embedded therein by the mounting groove of mounting groove unit two sides more than half, refer to
Fig. 4, from the cross section of mounting groove, the center of circle 12 of cable to be installed is located at the inside of mounting groove both ends line, and mounting groove
Opening width be less than the diameter of cable to be installed, and then ensure that cable to be installed is reliably fixed on the mounting groove of two sides
In.On this basis, the center of cable to be installed is and then adjacent away from the diameter for being less than cable to be installed in the adjacent mounting groove
Cable to be installed in mounting groove squeezes mutually, so that all cable installations to be installed are reliable.Especially when mounting groove is three
When above, then the cable to be installed in the mounting groove of two sides squeezes intermediate cable to be installed, and then guarantees intermediate line to be installed
The installation of cable is reliable.Cable can be prevented sagging by this kind of coil brace and deviated, guarantee electric energy efficiency of transmission.
Wherein, in conjunction with Fig. 4, what the mounting groove of two sides respectively referred to generation is the mounting groove of upside and the mounting groove of downside.
Referring again to Fig. 4: being mounted between intermediate cable to be installed and the cable to be installed for being mounted on two sides and be
It is full of cooperation.In cable installation session to be installed, the cable to be installed of lower two sides is installed first, is clamped in mounting groove,
Then the cable to be installed for installing middle position, by the interference fit jam-packed with upper and lower two sides cable to be installed in intermediate peace
In tankage.
According to one embodiment of present invention, the opening direction of the mounting groove court of two sides towards opposite side tilt namely Fig. 4 on
The installation channel opening of side is tilted towards downside direction, and the mounting groove opening direction of downside is tilted towards upper side direction.And then two sides
Mounting groove can apply a power namely upside inwards to cable to be installed therein mounting groove can give it is therein wait pacify
One downward power of wiring cable, and downside mounting groove can give one upward power of cable to be installed therein, and then can make
Cable to be installed is reliably mounted in the mounting groove.
According to one embodiment of present invention, rack body 9 includes upper bracket and lower bracket, is divided in upper bracket and lower bracket
It is not formed with mounting groove unit, cable to be installed is the first section and the second section of transmitting coil 1, the mounting groove on upper bracket
Unit is for fixing the first section, and the mounting groove unit on lower bracket is for fixing the second section, the first section and the second section
In parallel.
One of embodiment according to the present invention, provides contactless power supply system transmitting terminal, including arbitrarily organizes above-mentioned non-
It contacts power supply system and emits end unit.
Wherein, when the quantity of contactless power supply system transmitting end unit is multiple groups, adjacent contactless power supply system transmitting
The flow direction of the transmitting coil 1 of end unit on the contrary, can reduce the external electromagnetism spoke of contactless power supply system transmitting terminal in turn
Penetrate emission level.
One of embodiment according to the present invention provides a kind of vehicle, especially rail vehicle, including above-mentioned non-contact
Power supply system transmitting terminal.
The above embodiments are only used to illustrate the present invention, rather than limitation of the present invention.Although referring to embodiment to this hair
It is bright to be described in detail, those skilled in the art should understand that, to technical solution of the present invention carry out it is various combination,
