Abstract
The utility model relates to improvement of a steel anchor in electric power fittings. Disclosed is the steel anchor. The steel anchor is simple in structure, good in seal effect and capable of improving service life. The steel anchor comprises an anchor rod and a pull ring. The anchor rod is provided with a straight-bar section and a press connection section. A plurality of ring grooves are placed on the surface of the press welding section. The axial section of the ring groove is a concave arc shape. The adjacent ring grooves are connected through bulge rings. The axial section of the bulge ring is a bulge arch shape. Compared with the prior art, a connecting portion of a strain aluminum pipe press connection (the axial section being a rectangle) is improved. Because the wave-shaped ring grooves with the axial section are connected, during the work process, damages resulting from the press connection are avoided, service life is prolonged and meanwhile, penetration of outer hydrosphere can be effectively avoided and sealing property is good. The steel anchor is reliable to connect and convenient to handle.
Description
Technical field
The utility model relates to the improvement of steel anchor in the electric armour clamp.
Background technique
In the prior art, the steel anchor is in electric armour clamp connects, be located at an end of strain clamp, the steel anchor is connected crimping to connect with the strain insulator aluminum pipe, as shown in Figure 2, and the rectangular dentation of crimp segment axial cross section at normally used steel anchor middle part, in the process that connects, the bulge loop on compression groove both sides easily is damaged, and sealing is poor, easily water inlet.
The model utility content
The utility model provides a kind of simple in structure for above problem, and good sealing effect improves the steel anchor in working life.
The technical solution of the utility model is: comprise anchor pole and draw ring, described anchor pole is provided with straight bar section and crimp segment, is provided with some circular grooves on the surface of described crimp segment, and the axial cross section of described circular groove is concave arc shape.
Adopt bulge loop to link to each other between the described adjacent annular groove, the axis cross section of described bulge loop is convex.
Steel anchor of the present utility model has improved in the prior art joint with strain insulator aluminum pipe crimping (being that axial cross section is rectangular), adopt the circular groove of axial cross section undulate to connect, it in the course of the work, the damage of having avoided crimping to cause, improved working life, simultaneously, effectively prevent the infiltration of outside aqueous vapor, good seal performance.The utility model connects reliable, is convenient to processing.
