Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
Embodiment one: a kind of tramcar groove-shape rail Special grounding wire clip 1 of the groove-shape rail 3 for connecting insulated conductor 2 and tramcar, comprise earthing clamp body 11, magnetic means, insulated conductor 2 is fixedly connected with earthing clamp body 11 by coupling assembling.
Earthing clamp body 11 has the profile with the mating shapes of the groove on groove-shape rail 3.Concrete, groove-shape rail 3 offers groove, and the cross section of this groove takes the shape of the letter U, and the cell wall that two of groove are relative is plane, and bottom land is then arc-shaped curved surface.Usually, the width of its notch is slightly larger than the width of bottom land.So, earthing clamp body 11 also has the side matched with the cell wall of groove and bottom land, at the notch place of groove, earthing clamp body 11 has a upper surface 13 to connect the two ends of its side, and at the other two ends place of side, be provided with two side end faces 14 being approximately perpendicular to side and upper surface 13, thus form the profile of earthing clamp body 11 by above-mentioned side, upper surface 13 and two side end faces 14.Therefore, this earthing clamp body 11 can put into the groove also perfect cooperation with it of groove-shape rail 3, and now, the side of earthing clamp body 11 contacts with the cell wall of groove and bottom land and forms a contact-making surface, be referred to as joint face 12, the cross section of the joint face 12 of this earthing clamp body 11 is also U-shaped.
Magnetic means is arranged in the inside of earthing clamp body 11, and it can be opened or close.When this magnetic means is opened, it can make whole joint face 12 that earthing clamp body 11 contacts with groove cell wall and bottom land or the part joint face 12 that contacts with cell wall or the bottom land of groove produce magnetic force.Magnetic means has the switch knob 15 that controller opens or cuts out, and this switch knob 15 can be arranged on a side end face 14 of earthing clamp body 11.Switch knob 15 has two gears, and a corresponding magnetic means is opened, and another is corresponding magnetic means closedown then.Magnetic means can be controlled to different gears by by-pass cock handle 15.
Insulated conductor 2 is connected to by coupling assembling on the upper surface 13 of earthing clamp body 11, thus realizes being fixedly connected with of insulated conductor 2 and earthing clamp body 11.Coupling assembling comprises terminal block 16, card line plate 17 and connector 18.Terminal block 16 comprises the fixed part in tabular be fixedly connected with the upper surface 13 of earthing clamp body 11, the wire connecting portion in tabular being connected with card line plate 17 and insulated conductor 2, and fixed part is connected in obtuse angle with wire connecting portion.Fixed part is connected on the upper surface 13 of earthing clamp body 11 by several bolts.Card line plate 17 is fixedly connected on the connecting portion of terminal block 16, forms the space that can clamp insulated conductor 2 between the connecting portion of card line plate 17 and terminal block 16, is also fixedly connected by bolt between terminal block 16 and card line plate 17.The end of insulated conductor 2 extends to the middle part of the connecting portion of terminal block 16 through the space terminal block 16 and card line plate 17, and is fixedly connected on terminal block 16 by connector 18 herein.Here, connector 18 adopts bolt, and the end of insulated conductor 2 is provided with the flat adapter sleeve 4 in local, and the plat part of adapter sleeve 4 has screw, and connector 18 is namely in the plat part time insulated conductor 2 of adapter sleeve 4 and the connection of connecting plate.
The switch knob 15 dozens of above-mentioned Special grounding wire clip 1 is at OFF gear (closedown gear), and the side of earthing clamp body 11 does not have magnetic attraction.During installation, earthing clamp body 11 is put into the U-shaped groove of U-lag shaped steel rail 3 by operating personnel along the cell wall of groove, then by switch knob 15 dozens at ON gear (unlatching gear), now, the joint face all or in part 12 of earthing clamp body 11 will produce magnetic attraction, earthing clamp is tightly adsorbed in U-shaped groove.During dismounting, again beat at OFF gear by the switch knob 15 of earthing clamp body 11 side, earthing clamp body 11 loses magnetic force, and earthing clamp can easily take out by groove by operating personnel.
Above-mentioned Special grounding wire clip 1 is mainly for the profile feature of U-shaped rail; the degree easy to use of binding operation personnel; with the planning that the aspects such as the degree of protection to groove-shape rail 3 surface are carried out in all directions; adopt the mode of passive magnetic switch; utilize the plane of U-shaped rail U-type groove both sides inwall as contact-making surface; by rotating switch on earthing clamp as locking (dismounting) handle, operating aspect, simply.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection range of the present utility model.
