Description
Technical field
The utility model is related to electrical equipment technical field more particularly to a kind of omnipotent ground connection crossover subs.
Background technology
Ground wire be protection staff with equipment safety together with safety curtain, be electrical employee lifeline.Ground wire is
The leakage current of device housings, drain voltage are imported into the earth, when device housings are there are when leakage current, drain voltage, protection staff
Touch the personal safety of electric leakage equipment.In practical work, seem simple since ground wire is used frequently and operated, easily
It makes one to generate decline in alertness, importance also tends to be ignored by people.There are problems that during use：It is grounded in real work
Line is usually directly wound, while be grounded and there is the phenomenon that splicing on ground stud or ground connection band iron.Lead to ground wire and ground connection
Net there are virtual connection or contact it is insecure, earthing mode is lack of standardization.Lose the protective effect of ground wire.
Ground wire in the work of reality is generally attached using canoe, typically on ground connection band iron or is connect
It is directly wound using bare copper wire on pile, ground wire is larger with the contact resistance of ground stud, and ground connection is insecure and virtual connection shows
As；In the place of no ground stud, it can only be often wound using the paint on ground connection band iron is wiped off, spend the time in this way
It is longer；Ground wire using lack of standardization, different persons select wiring length and thickness it is all different, at ground stud separating test scene
Far, there is the phenomenon that splicing in ground wire.
Utility model content
(1) technical problems to be solved are to provide a kind of omnipotent ground connection crossover sub, connector operation convenient to use
Specification.
(2) technical solution
The purpose of this utility model is achieved through the following technical solutions：
Omnipotent ground connection crossover sub provided by the utility model, including ground stud, ground wire plate, earthing clamp；
The ground stud lower end is fixed in the earth, and upper end is connect with ground wire plate, and the ground stud is placed in the earth
Lower end is provided with the earthing clamp for connecting ground wire.
Further, the ground wire plate is connect by earth stud with ground stud upper end；The earth stud and ground wire
Elastic component is provided between plate, the elastic component, which is set on earth stud, to be suitable for compressing ground wire plate.
Further, it is connected by screw bolts between the ground wire plate and earthing clamp, spiral shell is provided on the ground wire plate
Keyhole, the earthing clamp are connect by screw with bolt hole.
Further, ground connection expander is provided on the ground stud, the ground connection expander is used for dead earth stake.
(3) advantageous effect
Compared with the prior art and product, the utility model has the following advantages：
Omnipotent ground connection conversion grounding head provided by the utility model can be grounded different ground wire robusts.It shortens
The ground connection time of ground wire.It can be equipped with different experiment ground wires according to different experiment works, mark, specification system
One management.
Description of the drawings
Fig. 1 is ground connection crossover sub front view.

Specific embodiment
Understand for the ease of those of ordinary skill in the art and implement the utility model, below in conjunction with the accompanying drawings and be embodied
Mode is described in further detail the utility model.
As shown in the figure, the present embodiment provides a kind of omnipotent ground connection crossover sub, including ground stud, ground wire plate and ground wire
Folder；The ground stud lower end is fixed in the earth, and upper end is connect with ground wire plate, and the lower end that the ground stud is placed in the earth is set
It is equipped with the earthing clamp for connecting ground wire；
The ground wire plate is connect by earth stud with ground stud upper end；It is set between the earth stud and ground wire plate
Elastic component is equipped with, the elastic component, which is set on earth stud, to be suitable for compressing ground wire plate；
It is connected by screw bolts between the ground wire plate and earthing clamp, is provided with bolt hole on the ground wire plate, institute
Earthing clamp is stated to connect with bolt hole by screw；
Ground connection expander is provided on the ground stud, the ground connection expander is used for dead earth stake；So as to fulfill ten thousand
Conversion grounding head, which can be grounded, can be grounded different ground wire robusts.
Omnipotent ground connection conversion grounding head can be grounded different ground wire robusts.When shortening the ground connection of ground wire
Between.It can be equipped with different experiment ground wires according to different experiment works, mark, unified and standard management.
It is additionally provided with ground wire on ground stud provided in this embodiment to come off monitoring device, the ground wire comes off monitoring dress
It puts including alarm 41, stationary contact 42, spring movable contact 43, spring leaf 44 and battery 45；
The spring leaf is set between ground stud and earthing clamp, and the spring leaf is connect with spring, on the spring
Spring movable contact is provided with, the stationary contact is set between spring movable contact and spring leaf；Described alarm one end and stationary contact
Point connection, the other end are connect with battery；When earthing clamp is set on ground stud, spring moves tactile under the action of spring leaf
Point is detached from stationary contact, when earthing clamp and ground stud are detached from, spring leaf under the action of elastic force so that spring movable contact with
Stationary contact is combined together；Warning circuit has been connected, has sent out alarm light or sound；The alarm of the present embodiment is luminescent device or bee
Ring device；Spring movable contact is set on spring, as spring moves.
Above example is only a kind of embodiment of the utility model, and description is more specific and in detail, but cannot be because
