Detailed Description
the technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. Based on the embodiments only in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.
As shown in fig. 1 to 3, a detachable ground wire comprises a converter 1, wherein one side of the converter 1 is connected with a tail wire 2, the other side of the converter 1 is connected with a plurality of branch wires 3, the tail wire 2 and the branch wires 3 comprise wire noses 231 fixed at one end, a middle wire body 232 and connectors 233 fixed at the other end and used for being connected with the converter 1, the converter 1 is provided with threaded holes 10, the connectors 233 are inserted into the threaded holes 10 and connected with the converter 1 in a threaded manner, the converter 1 is internally fixed with a controller, current sensors which are equal in number to the branch wires 3 and respectively used for sensing the current of each branch wire 3 and indicator lamps 11 corresponding to each current sensor, the signal input end of the controller is connected with the current sensors, and the control output end of the controller is connected with the.
This earth connection is when using, the different equipment is connected to the line nose 231 that utilizes bifurcated line 3, rethread connector 233 will bifurcated line 3 and converter 1 connect, and utilize connector 233 to connect tail 2 equally, thereby play the effect that a plurality of equipment can be simultaneously through 2 earthings of tail, when arbitrary bifurcated line 3 damages or tail 2 damages in whole earth connection, can dismantle it down through connector 233, and change new tail 2 or bifurcated line 3, can not influence the use of whole earth connection, and because the difference of equipment, when needing to adjust that ground connection good one's place, also can be arbitrary to bifurcated line 3 or earth connection change, and is simple and convenient.
And, in the earth connection use, meet the long-time electric leakage of equipment or the too big condition of leakage voltage, can burn out the circuit, thereby lose the ground connection effect, consequently, the feedback signal that current sensor in the equipment can be ceaseless gives the controller, when the circuit at certain bifurcated line 3 place produced the electric current, when certain equipment electric leakage promptly, the signal value of current sensor feedback reaches the setting value in the controller, the pilot lamp 11 that this bifurcated line 3 of controller control was located is lighted this moment, in order to remind the staff, the equipment electric leakage that this bifurcated line 3 is connected, very big improvement the security.
Wherein, the connector 233 is compacted with the line body 232 through one end, and the other end realizes the connection effect with converter 1 threaded connection's mode.
Therefore, this earth connection can realize the quick assembly disassembly and the change alone of tail wire 2 and bifurcated line 3 through connector 233 to the different tail wire 2 length of configuration that can be arbitrary realizes can both satisfying the user demand to different devices, and, when tail wire 2 and bifurcated line 3 damaged, can change alone, saved a large amount of costs. Simultaneously, at converter 1 internally mounted current sensor, when the equipment that certain bifurcated line 3 is connected produced the electric leakage, corresponding current sensor just can sense the electric current to the pilot lamp 11 that corresponds through the controller control lights, thereby the people's pertinence of being convenient for inspection leakage equipment, improved the security performance.
Since the transducer 1 itself is made of a conductive material, an insulating sleeve is fitted over the outer layer of the transducer 1. Thereby avoiding the danger of electric shock when people touch. Meanwhile, the converter 1 is made of red copper due to its good conductivity and corrosion resistance.
a straight line body 232 is connected with one end of the connector 233 in a common compaction manner, so that a connection point needs to be protected, a fixed clamping piece 4 is sleeved at the connection position of the line body 232 and the connector 233, the fixed clamping piece 4 is of a round tube-shaped structure, a connection notch 41 is formed in the outer surface of the fixed clamping piece 4 along the length direction of the fixed clamping piece, and the inner surface of the fixed clamping piece 4 is matched with the outer surface of the line body 232. After the wire 232 and the connector 233 are compacted and fixed, the fixing clip 4 is sleeved on the connecting point from the gap along the length direction of the wire 232, so that the connection stability of the wire 232 and the connecting point is improved, and the situation that the connecting point is damaged by external force to cause electric leakage or poor release or even disconnection is avoided.
In addition, since the connector 233 is a solid metal head, the flexibility is low, and the location of the device to which the branch line 3 is connected is not fixed, the branch line 3 may be excessively bent at the connector 233, which is likely to accelerate the damage of the line 232 and also easily damage the connection point of the line 232 and the connector 233, so that the threaded hole 10 is provided as a universal locking hole, and the connector 233 can be fixedly connected in any direction inside the threaded hole 10, so that the connection point of the branch line 3 and the connector 233 can always maintain an angle close to the horizontal, and the service life of the grounding wire is prolonged.
The above is only the preferred embodiment of the present invention, and any person can make some simple modifications, deformations and equivalent replacements according to the present invention, all fall into the protection scope of the present invention.
