Description

Technical Field

[0001] The utility model relates to a grounding connector, belonging to the technical field of grounding. Background Art

[0002] The equipotential bonding of the ground wire means that in electrical installations, in order to ensure that the potentials between the equipment shell or each point of the grounding system are equal and prevent potential differences from occurring, a connection method is carried out. This process ensures that in the event of a fault, the current can be quickly discharged, reducing the risk of electric shock and the possibility of electrical fires. To determine which components or areas need to achieve equipotential bonding, it usually includes conductive parts such as metal shells, water pipes, and building steel structures. At present, it is a common implementation method of ground wire equipotential bonding to connect two components that require ground wire equipotential bonding with a wire crimped with terminal lugs at both ends, that is, to install the terminal lugs at both ends of the wire on the two components that require ground wire equipotential bonding with bolts. The disadvantage of this method is that there are fewer contact points between the end of the wire and the bonding component. When oxidation, rust, etc. occur between the terminal and the bonding component, it will affect the grounding effect. Therefore, it is necessary to design a grounding connector that can increase the contact points between the wire and the bonding component as needed. Content of the Utility Model

[0003] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a grounding connector to solve the problems put forward in the above background art. The utility model realizes increasing the contact points between the wire and the bonding component as needed, and improving the reliability of the bonding grounding.

[0004] In order to achieve the above purpose, the utility model is realized by the following technical solutions: A grounding connector includes a wire, terminal lugs are crimped at both ends of the wire, a connecting rod is installed on the terminal lug through a conductive connecting piece, the other end of the conductive connecting rod is installed with a conductive column rod, a plurality of column sleeves are sleeved on the column rod, a positioning screw for restricting the relative position of the conductive column sleeve and the column rod is threadedly connected to the outer surface of the column sleeve, a conductive column is installed on the side of the outer surface of the column sleeve away from the positioning screw, the cross-section of the conductive column is rectangular, a conductive tube is sleeved on the conductive column, a contact piece is installed at one end of the conductive tube away from the column sleeve, and a limiting screw for restricting the relative position of the conductive tube and the conductive column is threadedly connected to one side surface of the conductive tube.

[0005] Further, the connecting member includes a first semi-circular sleeve. A conductive first semi-circular sleeve is sleeved on the connection nose. A conductive second semi-circular sleeve is provided on one side of the first semi-circular sleeve. The second semi-circular sleeve is sleeved on the connection nose. The end of the connecting rod away from the column rod is fixedly connected to the second semi-circular sleeve. First connecting ears are fixedly connected to both ends of the first semi-circular sleeve. Two second connecting ears are fixedly connected to both ends of the second semi-circular sleeve. The first connecting ear is fixedly connected to the second semi-circular sleeve by means of screws and nuts in cooperation.

[0006] Further, the contact member includes a straight tube. A conductive straight tube is installed at the end of the conductive tube away from the column sleeve. A limiting ring is installed at the end of the straight tube away from the conductive tube. A conductive movable rod is inserted into the limiting ring. A conductive limiting head is installed at the end of the movable rod inside the straight tube. The limiting head is slidably installed inside the straight tube. A conductive disk is installed at the end of the movable rod outside the straight tube. A spring is provided between the conductive disk and the conductive tube. The spring is sleeved on the straight tube.

[0007] Further, a first threaded blind hole is provided on the surface of the column rod away from the connecting rod. A conductive threaded head is threadedly connected inside the first threaded blind hole. A conductive extension rod is installed at the end of the threaded head outside the first threaded blind hole. A second threaded blind hole is provided on the surface of the extension rod away from the threaded head. The second threaded blind hole has the same specification as the first threaded blind hole.

[0008] Further, a threaded sleeve communicating with the internal space of the column sleeve is installed on the outer surface of the column sleeve. The positioning screw is threadedly connected inside the threaded sleeve.

[0009] Further, the connecting rod and the column rod are of an integrally formed structure. The connecting rod is of an "L" shaped structure.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. The first semi-circular sleeve and the second semi-circular sleeve are installed on the connection nose by means of screws and nuts in cooperation, completing the assembly of the column rod and the connection nose, that is, a grounding channel is formed between the column rod and the wire, facilitating the disassembly of the column rod and the wire.

[0012] 2. Multiple column sleeves can be sleeved on the column rod as needed, and then the distance between the column sleeves is adjusted so that multiple conductive disks are all in contact with the cross-connecting component, realizing increasing the contact points between the wire and the cross-connecting component as needed, improving the reliability of cross-connecting grounding, and reducing the influence of oxidation, rust and other conditions occurring between the connection nose and the cross-connecting component on grounding.

[0013] 3. Adjust the length of the conductive post inserted into the conductive tube, and use the limit screw to restrict the relative position of the conductive post and the conductive tube, so as to change the distance between the conductive disc and the column rod, facilitating the adjustment of the relative position between the conductive disc and the cross-connecting component when the position of the wiring nose is restricted.

[0014] 4. After the conductive disc contacts the cross-connecting component, at this time, the conductive disc and the conductive tube act on each other to squeeze the spring, causing the spring to produce elastic deformation. At the same time, the movable rod drives the limit head to slide towards the inside of the straight tube. Under the action of the spring's resilience, there is a squeezing force between the conductive disc and the cross-connecting component, improving the tightness of the fit between the conductive disc and the cross-connecting component.

[0015] 5. When the length of the column rod does not meet the requirements, screw the threaded head on one extension rod into the first threaded blind hole on the column rod, and then screw the threaded head on one extension rod into the second threaded blind hole on the other extension rod. Thus, the length of the conductive structure formed by the extension rod and the column rod increases. Therefore, there is no need to produce column rods with a large length initially, and the length of the conductive structure formed by the extension rod and the column rod can be adjusted according to the on-site needs, improving flexibility.

The first semi-circular sleeve 3 and the second semi-circular sleeve 4 are installed on the terminal lug 2 by using the cooperation of the screw and the nut, completing the assembly of the column rod 8 and the terminal lug 2, that is, a grounding channel is formed between the column rod 8 and the wire 1, facilitating the disassembly of the column rod 8 and the wire 1.

[0025] Refer to Figures 1 - 3 , the other end of the conductive connecting rod 12 is provided with a conductive column rod 8, a plurality of column sleeves 10 are sleeved on the column rod 8, a threaded sleeve 15 threadedly connected to the outer surface of the column sleeve 10 and communicating with the internal space of the column sleeve 10 is provided, and a positioning screw 9 for restricting the relative position of the conductive column sleeve 10 and the column rod 8 is threadedly connected in the threaded sleeve 15. According to needs, a plurality of column sleeves 10 are sleeved on the column rod 8, and then the distance between the column sleeves 10 is adjusted so that a plurality of conductive discs 13 are all in contact with the bridging component, realizing increasing the contact points between the wire 1 and the bridging component according to needs, improving the reliability of the bridging grounding, and reducing the influence of oxidation, rust and other conditions occurring between the terminal lug 2 and the bridging component on the grounding.

[0026] Refer to Figures 1 - 3, on one side of the outer surface of the column sleeve 10 away from the positioning screw 9, a conductive column 11 with a rectangular cross-section is installed. A conductive tube 5 is sleeved on the conductive column 11. One side of the conductive tube 5 is threadedly connected with a limit screw 6 for restricting the relative position between the conductive tube 5 and the conductive column 11. Adjust the length of the conductive column 11 inserted into the conductive tube 5, and use the limit screw 6 to restrict the relative position between the conductive column 11 and the conductive tube 5, so as to change the distance between the conductive disk 13 and the column rod 8, which is convenient for adjusting the relative position between the conductive disk 13 and the cross-connecting component when the position of the wiring nose 2 is restricted.

When the length of the column rod 8 does not meet the requirements, screw the threaded head 21 on one extension rod 7 into the first threaded blind hole 16 on the column rod 8, and then screw the threaded head 21 on one extension rod 7 into the second threaded blind hole 22 on another extension rod 7. Thus, the length of the conductive structure formed by the extension rod 7 and the column rod 8 increases. Therefore, it is not necessary to produce a column rod 8 with a larger length initially, and the length of the conductive structure formed by the extension rod 7 and the column rod 8 can be adjusted according to the on-site needs, improving flexibility.
