Abstract
The utility model discloses a multi-head complete grounding wire and belongs to power supply or power distribution component. The multi-head complete grounding wire comprises an insulated junction box and more than two grounding wires led out of the junction box. More than two wire outlet holes are disposed on the sidewall of the junction box. One ends of the grounding wires are mutually and electrically connected in the junction box. The other ends of grounding wires pass through the wire outlet holes and then are connected with devices or an absolutely secure ground wire. The grounding wires of the multi-head complete grounding wire are connected in parallel. By using a principle that the total resistance of resistors is decreased after connected in parallel, the total resistance value of the grounding wires of the devices is greatly reduced. In addition, the multi-head complete grounding wire has advantages of low cost and easy and convenient use. After the multi-head complete grounding wire is used, simple and clear onsite grounding wire arrangement is achieved. Omitted connecting points are easy to discover and a situation of tangled onsite wire arrangement is eliminated. At present, complete devices are used in experiments frequently so the multi-head complete grounding wire has wide popularization prospect.
Description
Technical field
The utility model belongs to power supply or the parts used of distribution.
Background technology
During power test, every the skinny device in complete set of equipments that uses all needs ground connection, and a common skinny device is just used an earth connection.Because number of devices is numerous, so the quantity of earth connection is also a lot, is very easy to cause the situation of site grounding wire cabling confusion; Simultaneously, when cabling is chaotic, the wiring situation of each equipment is difficult for detecting, and while having ground wire misconnection or sky to connect, is not easy to be found, and easily causes inaccurate or other electric power accidents of result of the test etc.
The utility model content
The technical problems to be solved in the utility model is to provide the complete earth connection of a kind of bull simple in structure, easy to use, with low cost.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the complete earth connection of a kind of bull comprises the junction box of insulation and the earth connection more than two of being drawn by junction box; The sidewall of described junction box is provided with two with Top Leading-out Hole; A wherein end of each earth connection mutually is electrically connected in junction box, and the other end is connected with equipment or the ground wire that is perfectly safe after wire hole.
The circular cylindrical cavity that described junction box is a hollow, the wire hole on the cylindrical cavity body sidewall is circular.
The quantity of described wire hole equates with the quantity of earth connection and is evenly distributed on the sidewall of junction box.
Each earth connection is moulded annealed copper wire by envelope and is formed.
The wire clamp that the open end of each earth connection is provided with ground connection or the equipment that connects is used.
The technological progress that adopts technique scheme to obtain is: in the utility model, each earth connection is arranged in parallel, utilize the principle that all-in resistance diminishes after the resistance parallel connection, reduce widely the total resistance value of equipment ground line, and have cost low, use simply, advantage easily; After using the utility model, on-the-spot ground connection cabling is simple, clear, and is convenient to find drain contact, has eliminated the situation of on-the-spot cabling confusion; Now use in test complete set of equipments more, therefore the utlity model has promotion prospect greatly.
The accompanying drawing explanation
Figure 1 shows that structural representation of the present utility model;
Wherein, 1, earth connection, 2, junction box, 3, wire hole, 4, wire clamp.
Embodiment
Known as shown in Figure 1, the complete earth connection of bull, comprise the junction box 2 of insulation and four earth connections 1 of being drawn by junction box 2; The sidewall of described junction box 2 is provided with four equally distributed wire holes 3; A wherein end of each earth connection 1 is in the interior mutual electrical connection of junction box 2, and the other end is connected with the equipment that needs ground connection or the ground wire that is perfectly safe after wire hole 3.
The circular cylindrical cavity that described junction box 2 is a hollow, the wire hole 3 on the cylindrical cavity body sidewall is circular.
Each earth connection 1 is moulded annealed copper wire by envelope and is formed.
The wire clamp 4 that the open end of each earth connection 1 is provided with ground connection or the equipment that connects is used.
Using method of the present utility model is: the at first selected ground wire be perfectly safe, and wherein an earth connection 1 is received on this ground wire by wire clamp 4; Then according to the position of testing equipment, the earth connection 1 of selecting correct position is connected.Because the wherein end of each earth connection 1 is electrically connected mutually, and wherein one has been connected on the ground wire be perfectly safe, so just be equivalent to all earth connections 1 and all be connected on the ground wire be perfectly safe, in like manner, also just be equivalent to testing equipment and received on safe ground wire.
In the utility model, the quantity of earth connection 1 quantity of the equipment of ground connection is as required selected.The quantity of junction box 2 Top Leading-out Holes 3 is usually consistent with the quantity of earth connection 1.
Wire hole 3 can be uniformly distributed on the sidewall of junction box 2, also can non-uniform Distribution.The shape of junction box 2 can be circle, can also be rectangle, hexagon etc.
One end of each earth connection 1, in the interior electrical connection of junction box 2, can be that each termination directly is connected, and can be also that the termination of each earth connection 1 is welded on a bit, like this, just need to a base be set in junction box 2 inside and weld these terminations; Binding post can also be set on base, and each termination all is connected with binding post.
The quantity of described wire hole 3 can equate with the quantity of earth connection 1, can certainly be greater than the quantity of earth connection 1, so that increase earth connection 1 use later.The shape of wire hole 3 is identical with the shape of earth connection 1 cross section, and area is slightly bigger.
The open end of earth connection 1 arranges wire clamp 4, to facilitate, is connected.The large I of wire clamp 4 is selected according to actual conditions.Certainly, except wire clamp 4, can also select other types of attachment, such as directly connecting etc. by wire.
After using the utility model, the earth connection be connected with each equipment is equivalent to be arranged in parallel, be well known that, after the resistance parallel connection, all-in resistance diminishes, equally, the total resistance value that is equivalent to greatly reduce the equipment ground line after each earth connection is arranged in parallel, earth connection has just diminished greatly on the operation conditions impact of equipment like this, has improved the accuracy of result of the test.The utility model is simple in structure, with low cost, uses also very simple and easy; After using the utility model, the ground connection cabling of testing ground equipment becomes simple, clear, also is convenient to find drain contact, has eliminated the situation of on-the-spot cabling confusion.Owing to using complete set of equipments more in test, required earth connection is also more, therefore the utlity model has promotion prospect greatly.
