Abstract
The utility model discloses a grounding wire for prolonging safety operating time, which comprises a wire clamp, an insulating rod, a crimping pipe, a copper pig tail and a soft copper wire, wherein a spring sleeves the crimping pipe and the soft copper wire, and the front end of the spring is hooked on the copper pig tail. The grounding wire is reasonable in structure, and effectively prolongs the service life; and the safety operating time of the grounding wire is increased by about 2 to 3 months than before, the maintenance cost is reduced, and the safety coefficient of personal and equipment is improved.
Description
Technical field
The utility model relates to a kind of power equipment earth connection.
Background technology
On power equipment, work, earth connection is to guarantee one of safe technical measures, and earth connection is well to guarantee safe primary condition.After one secondary brand-new complete earth connection is long between in use, in the junction of annealed copper wire and aluminium hydraulic pressed connecting pipe, easily damage.There is shape sudden change in earth connection aluminium hydraulic pressed connecting pipe and annealed copper wire tie point place.During work, annealed copper wire will launch conventionally, recovery etc., and from mechanics angle analysis, this tie point place stress is the most concentrated, so this tie point place the most easily damages.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the earth connection of the prolongation safe handling time of long service life.
Technical solution of the present utility model is:
Extend the earth connection of safe handling time, comprise wire clamp, insulating bar, aluminium hydraulic pressed connecting pipe, copper lug, annealed copper wire, it is characterized in that: a spring housing is contained on aluminium hydraulic pressed connecting pipe and annealed copper wire, and the front end of spring is hooked on copper lug.
Spring housing is contained in the connecting portion of aluminium hydraulic pressed connecting pipe and annealed copper wire.
The utility model is rational in infrastructure, effectively increases the service life.On annealed copper wire, aluminium hydraulic pressed connecting pipe, overlap a spring; spring one end is hooked on copper lug; the existing protection of " soft " property to annealed copper wire feature; " firmly " property protection feature that has again pair annealed copper wire; spring entangles firm on aluminium hydraulic pressed connecting pipe, annealed copper wire; one integrated mass, the power that acts on aluminium hydraulic pressed connecting pipe and annealed copper wire tie point place originally transfers outwards to shift by spring, and discharge final dispersion.When longitudinally pullling annealed copper wire, because spring is fixed on annealed copper wire, spring just produces reverse resistance, protects inner annealed copper wire; When radial distorted or bending annealed copper wire, spring can produce reverse resistance equally, offsets with external force, protects inner annealed copper wire.
The utility model earth connection safe handling time has increased approximately 2 ~ 3 months than originally, reduced maintenance cost, has improved coefficient of safety personal, equipment.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the structural representation of removing after spring.
Embodiment
Extend the earth connection of safe handling time, comprise wire clamp 1, insulating bar 2, aluminium hydraulic pressed connecting pipe 3, copper lug 4, annealed copper wire 5; Wire clamp is connected with insulating bar, and aluminium hydraulic pressed connecting pipe is connected with annealed copper wire, and aluminium hydraulic pressed connecting pipe is connected on wire clamp by copper lug; A spring 6 is sleeved on aluminium hydraulic pressed connecting pipe and annealed copper wire, and the front end of spring is hooked on copper lug.
Preferably spring housing is contained in the connecting portion of aluminium hydraulic pressed connecting pipe and annealed copper wire.
Claims (2)
1. extend the earth connection of safe handling time, comprise wire clamp, insulating bar, aluminium hydraulic pressed connecting pipe, copper lug, annealed copper wire, it is characterized in that: a spring housing is contained on aluminium hydraulic pressed connecting pipe and annealed copper wire, and the front end of spring is hooked on copper lug.
2. the earth connection of prolongation safe handling time according to claim 1, is characterized in that: spring housing is contained in the connecting portion of aluminium hydraulic pressed connecting pipe and annealed copper wire.
