The utility model content
The technical problems to be solved in the utility model is, overcomes the deficiency of above-mentioned prior art, and a kind of ground wire-terminal connector that is used for the integrated ground system is provided, and it can omit above-mentioned lengthy and jumbled connected mode, directly ground wire is connected with earth terminal; And attachment security is reliable, and connection procedure has that cost is low, instrument is simple, easy to operate, advantage such as artifical influence factor is little, and it is little to connect the back contact resistance, can satisfy the grounding requirement of railway combined grounding system.
The ground wire-terminal connector that is used for the integrated ground system according to the utility model provides is used to connect earth terminal and Through ground wire, and this connector comprises: body; Wiring nose is located at an end of described body, is electrically connected with described earth terminal; Cable clamping interface is located at the other end of described body, is electrically connected with described Through ground wire.
Preferably, described body be shaped as L shaped.
Preferably, described Wiring nose is formed at the upper end of the perpendicular arm of described L shaped body, and described cable clamping interface is formed at the front end of the transverse arm of described L shaped body.
Preferably, the outward flange of described Wiring nose is an arc, and its middle part is formed with through hole.
Preferably, described through hole can pass for the bolt that cooperates with the endoporus of described earth terminal.
Preferably, described cable clamping interface is by constituting from the extended a pair of cable clamping interface wall that is parallel to each other of described body.
Preferably, described cable clamping interface wall end formed has the inclined-plane.
Preferably, described body and described Wiring nose and described cable clamping interface are integrally formed.
Compared with prior art, the ground wire-terminal connector that is used for the integrated ground system of the present utility model has following advantage:
At first, it directly is connected ground wire with earth terminal, can omit link lengthy and jumbled in the prior art, and fastening means is simple, easy to operate, thereby greatly reduces the cost input of railway, Line for Passenger Transportation project.
Secondly, connected mode is safe and reliable, greatly reduces because the influence that human factor causes the reliability of railway signal transmission system.
Once more, can save a large amount of continuing and joint, thereby make grounding resistance less, to realize the requirement of the Ministry of Railways ground connection system earth resistance.

Embodiment
Below in conjunction with accompanying drawing feature of the present utility model and technology contents are elaborated.
Referring to Fig. 2 A, 2B, according to ground wire-terminal connector that the utility model provides, be used to connect earth terminal and Through ground wire, it comprises body 2, Wiring nose 3 and cable clamping interface 4.Body 2 is made by electric conducting material, is preferably metal material, for example copper or stainless steel.Wiring nose 3 and cable clamping interface 4 lay respectively at the two ends of body 2, and shown in Fig. 3 A, 3B, the two is respectively applied for earth terminal 7 and Through ground wire 8 and is electrically connected.
In preferred embodiment of the present utility model, being shaped as of body 2 is L shaped, and itself and Wiring nose 3 and cable clamping interface 4 are integrally formed.The connector of this structure is not only easy to use, and is easy to processing, low production cost.
Shown in Fig. 2 A, 2B, Wiring nose 3 is formed at the upper end of the perpendicular arm of described L shaped body 2, and cable clamping interface 4 is formed at the front end of the transverse arm of described L shaped body 2.The outward flange of Wiring nose 3 is an arc, and its middle part is formed with through hole 9.The outward flange of arc helps eliminating stress concentrated.
Shown in Fig. 3 A, 3B, through hole 9 can be for the bolt 7 that cooperates with the endoporus of earth terminal 7 ' pass.Behind the bolt 7 ' pass through hole 9, cooperate with the inner hole thread of earth terminal 7, thereby this connector is connected with earth terminal 7.Usually, the slightly larger in diameter of through hole 9 is in the diameter of bore of earth terminal 7.In preferred embodiment of the present utility model, the diameter of through hole 9 is φ 16.5mm, and the diameter of bore of earth terminal 7 is M16, so the bolt 7 of M16 ' can pass through hole 9 to cooperate with the endoporus of earth terminal 7.If selecting internal thread for use is the earth terminal of other specifications, then the size of through hole 9 need correspondingly be adjusted with corresponding with it.Those skilled in the art can design through hole 9 according to the conventional knowledge of the specification utilization of the internal thread of earth terminal in the actual use occasion.
Shown in Fig. 2 B, cable clamping interface 4 is by constituting from the body 2 extended a pair of cable clamping interface walls 41 that are parallel to each other, and cable clamping interface wall 41 end formed has inclined-plane 411.Earlier Through ground wire 8 is put into draw-in groove 41 during installation, and then exert pressure to two cable clamping interface walls 41 by device for exerting (as the pressure hydraulic tongs), thereby make two direction distortion that cable clamping interface wall 41 is close towards each other, and Through ground wire 8 is pressed on the inside of cable clamping interface 4.Form the state shown in Fig. 3 A, 3B at last.Through ground wire 8 is fixedlyed connected with this connector.Wherein, inclined-plane 411 helps cooperatively interacting after the distortion of two cable clamping interface walls 41.
Therefore, by ground wire-terminal connector of the present utility model, can realize effectively that Through ground wire 8 is connected with the reliable of earth terminal 7.
Certainly, above-mentioned preferred embodiment only supplies explanation the utility model, and is not to be used for the utility model is limited.In other embodiment, the outward flange of Wiring nose 3 can be other shapes, as square.Body 2, Wiring nose 3 and cable clamping interface 4 can be non-integrally formed, but combine by welding or other methods of attachment.The global shape of body 2 also can be down " fourth " font, or the like.Therefore the technical scheme that is equal to all belongs within the protection range of the present utility model.Protection range of the present utility model limits with appended claims.
