Embodiment
To shown in Figure 3, a kind of jointing clamp of electric meter comprises lower plate 1, first train wheel bridge 2 and second train wheel bridge 3, and a securing member 4 like Fig. 1.First train wheel bridge 2 and second train wheel bridge 3 are located in the lower plate 1, are used for fixing to connect backbone 5 and service wire 6.
First train wheel bridge, 2 left ends are provided with an open slot 21, cooperate clamping backbone 5 with the bend of lower plate 1 left end; The left end of the right-hand member and second train wheel bridge 3 is hinged.In the present embodiment, this first train wheel bridge 2 is a mother tuber, and second train wheel bridge 3 carries out hinged for public piece.
Second train wheel bridge 3 is a public piece, and left end is that the right-hand member of a face of cylinder and first train wheel bridge 2 is hinged, and right-hand member is that the right-hand member of a face of cylinder and lower plate 1 is hinged.In order to fix the relative rotation angle of this second train wheel bridge 3 and lower plate 1, the middle part of this second train wheel bridge 3 (between the left and right hinged place) also is provided with first fin 31 along the front and rear direction extension.After this second train wheel bridge 3 relatively rotates certain angle with lower plate 1, promptly blocked and can't carry out step rotation by this first fin 31, make this second train wheel bridge 3 only can rotate within the specific limits with lower plate 1, conveniently install and use.
See also Fig. 3, the side of this second train wheel bridge 3 also is provided with a skewed slot 32, and skewed slot 32, and is communicated with said wire through-hole 11 to upper right extension from the right-hand member of second train wheel bridge, 3 bottom surfaces.Because wire through-hole 11 has two, so this skewed slot 32 also should be two mutually.Also be provided with the groove 33 that is communicated with this skewed slot 32 in the bottom surface of this second train wheel bridge 3, service wire 6 passes among skewed slot 31 these grooves 32 of back arrival from wire through-hole 11.Sidewall end face between the groove 32 also is provided with some protruding teeth 34.Lower plate 1 medial surface also is provided with second fin with these protruding tooth 34 corresponding positions, and this second fin is indenting with this protruding tooth 34 and is provided with.Second fin comprises the left fin 12 and right fin 13 that is arranged at these protruding tooth 34 left and right sides respectively.Left side fin 12 is provided with some first stripeds that extend along fore-and-aft direction, prevents the landing of service wire 6.Right fin 13 is that a cross section is the pawl shape that is tilted to the left, and when can prevent the landing of service wire 6, can also prevent that second train wheel bridge 3 from deviating from from lower plate 1.
Securing member 4 comprises a screw bolt and nut, and bolt passes this first train wheel bridge 2, second train wheel bridge 3 and lower plate 1 in first train wheel bridge 2 and second train wheel bridge, 3 hinged places, and first train wheel bridge 2, second train wheel bridge 3 and lower plate 1 are fastenedly connected.The bottom surface of lower plate 1 is provided with a slotted hole along the left and right directions extension, and bolt passes from this slotted hole.
Above-mentioned binding clip also comprises an insulating coating, and insulating coating holds this binding clip.
During use, earlier first train wheel bridge 2 and second train wheel bridge 3 are carried out hingedly, the right-hand member with second train wheel bridge 3 and lower plate 1 carries out hinged then; With first train wheel bridge 2 and second train wheel bridge 3 lift make itself and lower plate 1 form certain angle after, insert service wire 6 and backbone 5, then first train wheel bridge 2 and second train wheel bridge 3 are pressed among the lower plate 1, nut screwing clamping is got final product.
With respect to prior art, the lead that the utility model can directly differ line bigger easily connects, and not only is connected firmly, and can cause damage to lead; Secondly, be arranged at the anglec of rotation that first fin on second train wheel bridge can limit second train wheel bridge, make things convenient for wiring, make the installation and removal of the described jointing clamp of electric meter of the utility model become simple more, efficient.
More than describe the preferred embodiment of the utility model in detail, the ordinary skill that should be appreciated that this area need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technical staff in the art according to the utility model design on the prior art basis through logic analysis, reasoning perhaps according to the available technical scheme of limited experiment, all should be among determined protection range by these claims.
