Abstract
Description
Technical Field
[0001] The utility model provides a grounding wire with a grounding wire nose that is not easily broken, belonging to the technical field of power grounding wires. Background Art
[0002] The grounding wire is one of the indispensable safety measures in the electrical system. It is used to connect the casing or other non-live parts of electrical equipment to the ground to ensure the safety of people and equipment. Through the grounding wire, unexpected current can be effectively conducted into the ground to avoid electric shock accidents or equipment damage caused by leakage.
[0003] In order to ensure the safe grounding of electrical equipment and systems, a wire nose is used when the grounding wire is in use. However, when using the current wire nose, such as patent number: CN205178076U, the grounding wire is usually directly inserted into the connecting part of the wire nose, and then the connecting part of the wire nose is flattened to fix the wire nose and the grounding wire. Although this method can connect the wire nose to the grounding wire, in actual use, if the grounding wire is subjected to physical impact, the connection between the grounding wire and the wire nose may be disconnected. Utility Model Content
[0004] The technical problem to be solved by the utility model is that when the conventional wire nose is in use, the wire nose and the ground wire may be separated after the ground wire is subjected to physical impact.
[0005] In order to solve the above problems, the utility model proposes a technical solution: a grounding wire with a grounding wire nose that is not easy to break, comprising a grounding wire; the grounding wire is wound on a reel, one end of the grounding wire is elastically and telescopically arranged in the wire nose, and the other end is elastically and telescopically arranged in the handle of the crocodile clip.
[0006] As an improvement, the wire nose includes a connecting portion and a fixing portion, wherein a T-shaped hole is provided in the connecting portion, and the end of the T-shaped hole passes through the side wall of the connecting portion in an arc shape, and a spring is provided in the T-shaped hole;
[0007] As an improvement, the inner diameter of spring 1 is larger than the diameter of the grounding wire, and the outer diameter is the same as a portion of the T-shaped hole with a large diameter;
[0008] As an improvement, the alligator clip includes two hinged handles, one of which is provided with a second T-shaped hole, the end of the second T-shaped hole being arc-shaped and passing through the side wall of the handle, and a second spring being provided in the second T-shaped hole;
[0009] As an improvement, the inner diameter of the second spring is larger than the diameter of the grounding wire, and the outer diameter is the same as the larger diameter portion of the second T-shaped hole.
[0010] Beneficial effects of the utility model:
[0011] By winding the grounding wire on the reel, the length of the grounding wire can be changed as needed during use. By elastically stretching the two ends of the grounding wire in the wire nose and the handle of the crocodile clip, the end of the grounding wire can be contracted when the grounding wire is impacted, thereby avoiding the connection with the wire nose and the crocodile clip from being disconnected. When the grounding wire is impacted, the reel will also be driven to rotate, thereby releasing part of the grounding wire, which can also prevent the connection with the wire nose and the crocodile clip from being disconnected.

[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] according to Figure 1 —3: The utility model provides a grounding wire with a grounding wire nose that is not easy to break: comprising a grounding wire 1; the grounding wire 1 is wound on a reel 2, one end of the grounding wire 1 is elastically and telescopically arranged in the wire nose 3, and the other end is elastically and telescopically arranged in the handle 401 of the crocodile clip 4; by winding the grounding wire 1 on the reel 2, the length of the grounding wire 1 can be changed as needed during use, and by elastically and telescopically arranging the two ends of the grounding wire 1 in the wire nose 3 and the handle 401 of the crocodile clip 4 respectively, when the grounding wire 1 is impacted, the end of the grounding wire 1 can be contracted, thereby preventing the connection with the wire nose 3 and the crocodile clip 4 from being disconnected, and when the grounding wire 1 is impacted, the reel 2 will also be driven to rotate, thereby releasing part of the grounding wire 1, which can also prevent the connection with the wire nose 3 and the crocodile clip 4 from being disconnected;
[0018] according to Figure 1 、 2As shown: the wire nose 3 includes a connecting portion 301 and a fixing portion 302, a T-shaped hole 303 is provided in the connecting portion 301, the end of the T-shaped hole 303 is arc-shaped and passes through the side wall of the connecting portion 301, and a spring 304 is provided in the T-shaped hole 303; the inner diameter of the spring 304 is larger than the diameter of the grounding wire 1, and the outer diameter is the same as the large diameter part of the T-shaped hole 303; in this way, by passing one end of the grounding wire 1 through the T-shaped hole 303 and then tying a knot at the end of the grounding wire 1, the knotted part is located in the arc part of the T-shaped hole 303, and the diameter is the same as the large diameter part of the T-shaped hole 303. In this way, when the grounding wire 1 is impacted, the knotted part will be driven to move toward the small diameter part of the T-shaped hole 303, and the spring 304 will be driven to contract, so as to ensure the connection between the grounding wire 1 and the wire nose 3. At the same time, after the impact, under the action of the spring 304, the knotted part of the grounding wire 1 will return to the arc part of the T-shaped hole 303;
[0019] according to Figure 1 、 3 As shown, the alligator clip 4 includes two hinged handles 401, one of which is provided with a second T-shaped hole 402. The end of the second T-shaped hole 402 is arc-shaped and passes through the side wall of the handle 401. A second spring 403 is provided in the second T-shaped hole 402. The inner diameter of the second spring 403 is larger than the diameter of the grounding wire 1, and the outer diameter is the same as the large diameter portion of the second T-shaped hole 402. In this way, by passing the other end of the grounding wire 1 through the second T-shaped hole 402 and then tying a knot at the end of the grounding wire 1, the knotted portion is located in the arc portion of the second T-shaped hole 402 and has the same diameter as the large diameter portion of the second T-shaped hole 402. In this way, when the grounding wire 1 is impacted, the knotted portion will be driven to move toward the small diameter portion of the second T-shaped hole 402, and the second spring 403 will be driven to contract, thereby ensuring the connection between the grounding wire 1 and the alligator clip 4. At the same time, after the impact, under the action of the second spring 403, the knotted portion of the grounding wire 1 will return to the arc portion of the second T-shaped hole 402.
[0020] The principle of the utility model is as follows: when in use, first pass the two ends of the grounding wire 1 through the T-shaped hole 303 and the T-shaped hole 402 respectively, then tie a knot at the two ends of the grounding wire 1, and make the outer edges of the knotted parts fit the arc parts of the T-shaped hole 303 and the T-shaped hole 402 respectively, then release the grounding wire 1 through the reel 2, and then connect the wire nose 3 and the alligator clip 4 to the ground and the electrical appliance respectively, and then adjust the position of the reel 2 so that the reel 2 does not affect the normal operation of the workers. In this way, the device is set up;
[0021] When the grounding wire 1 is impacted, the knotted parts at both ends of the grounding wire 1 will be driven to move toward the small diameter parts of the T-shaped hole 1 303 and the T-shaped hole 2 402 respectively, and the spring 1 304 and the spring 2 403 will be driven to shrink. If the impact is too large, after the spring 1 304 and the spring 2 403 shrink to the limit position, the reel 2 will be driven by the grounding wire 1 to fall over, thereby releasing the grounding wire 1 and increasing the length of the grounding wire 1. This can ensure the connection between the grounding wire 1 and the wire nose 3 and the alligator clip 4. At the same time, after the impact is over, under the action of the spring 1 304 and the spring 2 403, the knotted part of the grounding wire 1 will be reset.
[0022] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
