Embodiment
Describe by the following examples the technical solution of the utility model in detail, should be understood that, following embodiment is only exemplary, only can be used for explaining and explanation the technical solution of the utility model, and can not to be interpreted as is the restriction to technical solutions of the utility model.
As shown in Figure 1, Figure 2 and Figure 3, a kind of grounding leg of crosslinked cable joint copper shell, includes two grounding legs (4,6), and each grounding leg (4,6) includes copper rod (2,7) and is wrapped in the insulating barrier outside copper rod; On two, grounding leg connects respectively large copper pipe 8 and the little copper pipe 1 of copper shell; Described two grounding legs (4,6) are L shaped, and the one side wherein connecting for same earth connection is parallel with the center line of copper shell, the surface of the vertical copper shell in one side being connected with copper shell.Or described two grounding legs are connected respectively center on one side with earth connection and the line angle at copper shell center is 60 degree.In other embodiment of the application, two grounding legs can change being greater than between 0 degree to 180 degree with the angle of the line of copper shell, as long as convenient connect and use all can, but be preferably 60 degree angles.
In the present embodiment, be connected respectively the distance of the line at center on one side with earth connection be 140mm to described two grounding legs (4,6).In other embodiments, because the external diameter of copper shell can change according to the external diameter of cable is different, therefore the distance between two grounding legs also has respective change, but the structure of ground connection limb pin does not change.
Described copper rod (2,7) is L shaped, and the radial cross-section of described copper rod is circle, polygon, square or triangle.One side of copper rod connects with a copper pipe of copper shell, and another side is used for earth connection pressing; In described copper rod, near not wrap insulate layer of the side surface end on one side of same earth connection pressing, be exposed structure; Remainder is enclosed with insulating barrier, and in the present embodiment, what insulating barrier adopted is polypropylene, and in other embodiments, insulating barrier also can adopt other material; In copper rod (2,7), for one side of same earth connection pressing, the approaching not wall thickness of the insulating barrier 5 of the copper rod part of wrap insulate layer is less than the wall thickness of other parts insulating barrier 3; On the copper rod of described not wrap insulate layer, be provided with the groove 9 that three circles are parallel to each other, the cross-sectional centerline of described groove is perpendicular to the center line of copper rod.The setting of groove structure, when when by copper rod and earth connection pressing, earth connection can be packed into groove, thereby improves bond strength.
