The technical scheme of the invention is further described in detail by the following specific embodiments in combination with the attached drawings:
example 1
As shown in fig. 1, the present embodiment provides a magnetically-fixed ground clamp including a jaw-type ground clamp 1 and an insulated operating rod 2. Insulating bar 2 is equipped with joint section 3, and insulating bar 2 rotates with earth connection chuck 1 through joint section 3 to be connected.
Specifically, joint section 3 is equipped with horizontal pole 4 of metal material, and the length of horizontal pole 4 is greater than 1 openings of earth connection chuck, and 4 outmost ends of horizontal pole are equipped with metal sleeve 6, and metal sleeve 6 rotates fixedly with horizontal pole 4, and 4 middle sections of horizontal pole still leave sunken position, and the direction of sunken position is vertical upwards, effectively increases the area of contact with the cable.
In addition, earth connection chuck 1 divide into stiff end and open end, and the joint section 3 of insulating bar 2 rotates with the stiff end of earth connection chuck 1 to be connected, and the open end of earth connection chuck 1 is equipped with magnet 8, through rotating insulating bar 2, with horizontal pole 4 overlap joint to magnet 8 on, metal sleeve 6 and magnet 8 adsorb each other to the realization is fixed. The ground wire chuck 1 is further provided with a fixed bearing 7 for fixing the clamping section 3, and the fixed bearing 7 is rotatably connected to two ends of the clamping section 3.
Specifically, still the pre-compaction has spring 5 between joint section 3 and the earth connection chuck 1, and spring 5 locates 4 below on the horizontal pole and cup joints in joint section 3, and spring 5 one end is connected in joint section 3, and the other end is connected in earth connection chuck 1, has vertical ascending power and the rotatory power of turning around self to joint section 3. In order to ensure the complete grounding wire as far as possible, the spring 5 has vertical upward elastic force on the cross rod 4, and when the cross rod 4 is adsorbed to the magnetic part, the elastic force enables the cross rod 4 to be tightly attached to the cable upwards, so that the complete grounding wire is ensured.
