In circuit, overhaul of the equipments process, in order to ensure the safety of maintainer, use short-circuit grounding wire to be one of indispensable measure of protection, the earth resistance size of earth connection is directly connected to ground connection by rate.Reducing earth resistance effective ways is that to ensure that earth connection is connected with earth electrode reliably necessary.It is that bolt connects that the short-circuit grounding wire earth connection of current use is connected with earth electrode, often occurs bolt looseness in actual use, causes the phenomenon of earth connection loose contact, affect stability and the fail safe of circuit.
Utility model content
The purpose of this utility model solves prior art Problems existing, and provide a kind of structure simple, serviceability is stablized, and can ensure the Novel connecting ground wire jointing that earth connection reliably connects.
To achieve these goals, the utility model technical scheme of taking is this Novel connecting ground wire jointing provided, comprise the socket be fixedly attached on ground stud and the latch connecting earth connection, described latch sidewall is provided with two position-limitting pins be arranged symmetrically with, described socket is provided with the pin clamp that described latch is installed in corresponding grafting, is provided with position-limitting pin described in clamping to be fixedly connected with the limited step of described latch in described socket.
For making technique scheme more detailed and concrete, the utility model also provides following further optimal technical scheme, to obtain satisfied practical function:
Described latch is truncated cone-shaped structure, and be provided with three cylinder steps, described position-limitting pin is located on the outer wall of second step, and first step diameter is greater than described second step diameter, and described first step limiting card is connected to described pin clamp outer end.
The second step diameter of described latch is greater than the 3rd stepped diameters, and on described 3rd step, cover has spring.
The main body of described pin clamp is the column structure with the grafting of described second step dimensional fits, is provided with the slot of position-limitting pin described in corresponding grafting in the bilateral symmetry of described column structure.
Described spring supporting is in described socket inside bottom surface.
Described latch is turning integrated formed structure.
This Novel connecting ground wire jointing compared with prior art, has the following advantages: adopt fixed socket, in socket, car goes out rotary insertion lock-joint; Go out to move back at latch top car and pull out step, with mounting spring, bilateral symmetry place in the middle of latch, car goes out position-limitting pin, and latch rotates after insertion fixed socket, coordinates under the action of the spring, realizes more stable connection.This Novel connecting ground wire jointing structure is simple, fast easy to install, can ensure that on-the-spot ground connection is reliable, meet earth resistance requirement, ensure upkeep operation safety, the damage of institute's earth connection in installing/dismounting process can be avoided simultaneously, there is stronger practicality.
Accompanying drawing explanation
Below the content expressed by the accompanying drawing of this specification and the mark in figure are briefly described:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structural representation.
Be labeled as in figure: 1, socket, 2, latch, 3, position-limitting pin, 4, spring, 5, pin clamp.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail.
Novel connecting ground wire jointing of the present utility model, as shown in Figure 1, 2, comprises socket 1 and is plugged on the latch 2 in this socket 1, be fixedly attached on ground stud, short-circuit grounding wire be connected to the tail end of latch 2 during use by socket 1.Latch 2 sidewall is provided with two position-limitting pins 3 be arranged symmetrically with, socket 1 is provided with the corresponding pin clamp 5 installing latch 2, clamping position-limitting pin 3 is provided with to be fixedly connected with the limited step of latch 3 in socket 1, this latch 2 is inserted in socket 1 along pin clamp 5, in socket 1, rotate an angle limit pin 3 get final product clamping on limited step, realize fixing.The mode of this kind of socket connection can ensure that on-the-spot ground connection is reliable, meet earth resistance requirement, ensure upkeep operation safety, can avoid being wound around in earth connection process at dismounting earth connection simultaneously, cause the earth connection stock that breaks to damage the phenomenon of earth connection because ground stud is connected with earth connection, namely facilitate installing/dismounting.
In the utility model, as shown in Figure 1, 2, latch 2 is set to truncated cone-shaped structure, be provided with three cylinder steps, position-limitting pin 3 is located on the outer wall of second step, and first step diameter is greater than second step diameter, when grafting is installed, first step limiting card is connected on pin clamp 5 outer face, is namely in place.The second step diameter of latch 2 is greater than the 3rd stepped diameters, and on the 3rd step, cover has spring 4.Spring 4 is supported in socket 1 inside bottom surface, and by being located at the effect of latch 2 grafting top spring 4, the clamping that position-limitting pin 3 is more stable with limited step, can make latch 2 contact with socket 1 more firm.
Pin clamp 5 coordinates with latch, its main body is the column structure with the grafting of second step dimensional fits, the slot coordinating grafting with position-limitting pin 3 is provided with in the bilateral symmetry of column structure, the design that profiling coordinates facilitates grafting, alignment position-limitting pin 3 can be installed with slot in light grafting, rotates an angle and can realize stable connection after inserting.
In the utility model, latch 2 is turning integrated formed structure, and structure is more firm stable, can durablely use.
This Novel connecting ground wire jointing, by socket connection, facilitates installing/dismounting, and it is reliable to ensure that earth connection connects.Make a fixed socket 1, in socket 1, car goes out rotary insertion lock-joint 5; Go out to move back at latch 2 top car and pull out step, with mounting spring 4, the middle bilateral symmetry place of latch 2, car goes out position-limitting pin 3, and latch 2 rotates after insertion fixed socket 1, under being engaged in the effect of spring 4, realizes more stable connection.When using at the scene, socket 1 is weldingly fixed on ground stud, short-circuit grounding wire is welded on latch 2 afterbody, this Novel connecting ground wire jointing structure is simple, fast easy to install, can ensure that on-the-spot ground connection is reliable, meet earth resistance requirement, ensure upkeep operation safety, the damage of institute's earth connection in installing/dismounting process can be avoided simultaneously, there is stronger practicality.
