Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1-Figure 3, the utility model discloses a kind of contact wire splice, for connecting two contact wires 8.This contact wire splice comprises the first clamping element 1 and the second clamping element 2, and the first clamping element 1 in the present embodiment and the second clamping element 2 are bar shaped clamping plate, and beryllium-bronze material that is high by tensile strength, rub resistance is made; The side that first clamping element 1 is relative with the second clamping element 2 is formed respectively for coordinating the holding part of clamping contact wire 8 and for coordinating the location division fixing the first clamping element 1 and the second clamping element 2 relative position.First clamping element 1 is connected to apply gripping power to the contact wire 8 be held in holding part with the second clamping element 2 by bolt 5, and this location division and holding part lay respectively at the both sides of bolt 5; For ensureing that contact wire 8 is clamping stable, the quantity of bolt 5 is multiple, and be crisscross arranged along the length direction of the first clamping element 1 and the second clamping element 2 is positive and negative, the plurality of bolt 5 is preferably arranged near contact wire 8 place, makes that the thrust of two clamping elements is as much as possible to be acted on contact wire 8.In addition, between each bolt 5 and each clamping element, be also provided with Wedged retaining washer, be connected firmly between each bolt 5 and each clamping element for auxiliary.Wherein, the holding part of the first clamping element 1 and the second clamping element 2 is corresponding is respectively provided with for clamping and prevent the disconnecting prevention structure of contact wire 8 slippage simultaneously.
Further, as Fig. 2, shown in Fig. 3 and Fig. 4, this disconnecting prevention structure comprises the strip bulge arranged along the first clamping element 1 and the second clamping element 2 length direction, and the multiple chisel teeths 7 be located on this strip bulge, the plurality of chisel teeth 7 is arranged along the length direction of strip bulge, and two sections of mirror image are formed along strip bulge length direction, shown in concrete composition graphs 2 and Fig. 3, in the present embodiment, the plurality of chisel teeth 7 with the middle part of strip bulge for basic point formed left and right two sections, an all clamping contact wire 8 between two sections of chisel teeths 7 corresponding to the first clamping element 1 and the second clamping element 2 position, for preventing two reverse mobile slippages of contact wire 8, about this, the stub end of two sections of chisel teeths 7 is oppositely arranged, namely with in the middle part of strip bulge for basic point, the stub end of two chisel teeths 7 of positional symmetry is oppositely arranged, .Preferably, the location division of the first clamping element 1 is the location division of the protuberance arranged along its length 3, second clamping element 2 is with protuberance 3 respective outer side edges and the equal recess 4 of length.When the first clamping element 1 and the second clamping element 2 coordinate clamped contact line 8, two location divisions are engaged mutually, two clamping elements are located mutually up and down, simultaneously can compensate contact wire 8 own dimensions error and cause the position deviation of two clamping elements because of fastening deformation, without the need to more as in the prior art by adding equalizing conductor to ensure the locating effect of the first clamping element 1 and the second clamping element.
As shown in Figure 2 and Figure 4, first clamping element 1 is provided with fin 6 along its length away from a side of contact wire 8, the cross-sectional plane of this fin 6 is fan-shaped with the clip slot 9 forming two bar shapeds between the first clamping element 1, make conveniently to be connected with suspension clamp, without the need to suspension clamp again with wire clamp beyond anatomical connectivity, convenience and high-efficiency.
In order to clamping fastener contact wire 8, the two holding part opposite side part that is not provided with disconnecting prevention structure that can be more firm is the curved surface with contact wire 8 form fit.In addition, in order to ensure that wire clamp is in the junction transitions smooth of new and old contact wire 8, unlikely pantograph of injuring, the outer rim of two holding parts is curved to enable two joints (specifically see Fig. 1) of the coated new and old contact wire 8 in the middle part of two holding parts, facilitates pantograph steadily to slip over wire clamp.
Above embodiment is only exemplary embodiment of the present utility model, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can in essence of the present utility model and protection domain, and make various amendment or equivalent replacement to the utility model, this amendment or equivalent replacement also should be considered as dropping in protection domain of the present utility model.
