With the increasing degree of industrial automation and the increasingly stringent and precise requirements for industrial control, the use of terminal blocks has gradually increased. With the development of the electronics industry, the use of terminal blocks has become more and more diverse. In addition to PCB board terminals, the most widely used ones include hardware terminals, nut terminals, spring terminals, and so on.

[0003] In the power distribution cabinet, wiring terminals are also needed for connection. For example, when connecting a cable to a copper busbar (with bolts), wiring terminals are used for connection. When in use, the end of the wire is first connected to one end of the wiring terminal, and then the other end with an opening is sleeved onto the bolt, and then the wiring terminal is pressed onto the copper busbar using washers and nuts. However, in practice, in order to prevent the bolts and washers from falling off, nuts and washers are usually connected to the nuts before connection, and then the nuts and washers are first removed when connecting the wiring terminals; then the wiring terminals are sleeved onto the bolts, and finally the washers and nuts are connected to the bolts. This makes the bolts have a larger travel range, the operation is more complicated, and the efficiency is low. Utility Model Content

The same or similar reference numerals in the accompanying drawings represent the same or similar components.

[0024] A connection terminal assembly for a power distribution cabinet cable, such as Figures 1 to 6 As shown, including:

[0025] The terminal body 1 comprises a cylindrical body portion 1a and a sheet body portion 1b, one end of the sheet body portion 1b is connected to the cylindrical body portion 1a, and the other end is provided with a long strip-shaped engaging groove 2;

[0026] The connecting copper bar 3 is provided with a connecting bolt 4 perpendicular to the connecting copper bar 3 , and a connecting nut 5 is threadedly provided on the connecting bolt 4 . The connecting bolt 4 is engaged in the engaging groove 2 , and the sheet body 1 b is located between the connecting nut 5 and the connecting copper bar 3 .

[0027] A bending portion 6 is provided at a free end of the sheet body 1 b on one side close to the connecting copper busbar 3 . A stabilizing hole 7 is provided on the connecting copper busbar 3 . The bending portion 6 is located in the stabilizing hole 7 .

[0028] Both ends of the sheet body 1 b have the bending portions 6 , and two stabilizing holes 7 are provided.

[0029] The size of the longitudinal section of the stabilizing hole 7 is larger than that of the longitudinal section of the bending portion 6. When the top of the bending portion 6 abuts against the top of the stabilizing hole 7, the bottom of the bending portion 6 is higher than the bottom of the stabilizing hole 7, and both sides of the bending portion 6 have a set gap with the side walls of the stabilizing hole 7.

[0030] Two limiting parts 8 are provided on one side of the connecting copper busbar 3 close to the sheet body 1b. The two limiting parts 8 are respectively located on the outsides of the two stabilizing holes 7. The shape of the limiting part 8 matches the shape of the stabilizing holes 7. The sheet body 1b is located between the two limiting parts 8.

[0031] It also includes an auxiliary gasket 9, which is sleeved on the connecting bolt 4, and two sides of the auxiliary gasket 9 are attached to the connecting nut 5 and the sheet body 1b.

[0032] The connecting bolt 4 is provided with an annular temporary groove 10 , and the auxiliary gasket 9 is engaged with the top of the temporary groove 10 .

[0033] The utility model provides a connecting terminal assembly for a power distribution cabinet cable. First, when in use, the connecting copper bar 3 is fixed on the cabinet body of the power distribution cabinet, and at the same time, the connecting bolt 4 is also fixedly connected to the connecting copper bar 3, and the connecting nut 5 is also fixedly connected to the connecting bolt 4 to prevent it from falling during transportation or use; at the same time, the barrel portion 1a of the terminal body 1 is connected to the cable; then, when connecting the cable and the connecting copper bar 3, first, the connecting nut 5 is rotated to allow a certain gap to exist between the connecting nut 5 and the connecting copper bar 3, and then the engaging groove 2 is engaged with the connecting bolt 4 from top to bottom, and when the height of the sheet body portion 1b reaches the minimum, the connecting nut 5 is rotated in the opposite direction and the sheet body portion 1b is pressed against the connecting copper bar 3 by the connecting nut 5, so that the connection between the cable and the connecting copper bar 3 is achieved.

[0034] Whether between the connecting sheet body 1b or when fixing the sheet body 1b, the length or distance required to rotate the connecting nut 5 is small, that is, only the sheet body 1b needs to pass through the connecting nut 5 and the connecting terminal, thereby reducing the time for operating the connecting nut 5 and improving the operating efficiency. In addition, since there is no need to completely remove the connecting nut 5 from the connecting bolt 4, it is also possible to prevent the connecting nut 5 from being lost, etc., thereby improving the operating stability from the side.

[0035] In actual operation, firstly, the connection nut 5 is rotated to make the connection nut 5 away from the connection copper bar 3, and then the auxiliary gasket 9 is moved outward; then, the sheet body 1b is moved downward to make the engaging groove 2 engage with the outer side of the connection bolt 4, until the top of the engaging groove 2 abuts against the top of the connection bolt 4, and then the sheet body 1b is moved toward the connection copper bar 3 to make the sheet body 1b fit on the connection copper bar 3, and the bending portion 6 is inserted into the stabilizing hole 7;

[0036] Then, move the auxiliary gasket 9 toward the connecting copper bus 3, and after the auxiliary gasket 9 is attached to the sheet body 1b, move the auxiliary gasket 9 downward so that the bottom of the auxiliary gasket 9 is engaged with the top of the temporary groove 10; at this time, the auxiliary gasket 9 is limited by the temporary groove 10 and cannot move, so that the auxiliary gasket 9 can temporarily limit the sheet body 1b, and there is no need to worry about the sheet body 1b being separated from the connecting copper bus 3 under the action of the cable; finally, turn the connecting nut 5, the connecting nut 5 is pressed on the auxiliary gasket 9, and the sheet body 1b is pressed on the connecting copper bus 3 through the auxiliary gasket 9.

[0037] During use, the bottom of the sheet body 1b is buckled into the stabilizing hole 7 through the bending portion 6, so that the bending portion 6 can prevent relative movement between the sheet body 1b and the connecting copper bus 3, thereby ensuring the connection stability between the terminal body 1 and the connecting copper bus 3; at the same time, the two bending portions 6 are limited by the inner wall of the stabilizing hole 7, thereby further ensuring the angle of the terminal body 1, and at the same time ensuring the angle of the cable, preventing the cable from tilting, etc., and improving the stability of the cable in use.

[0038] When the connecting copper busbar 3 is produced, it is necessary to punch out the stabilizing hole 7, but the part punched out at the same time is the limiting portion 8, that is, the limiting portion 8 and the stabilizing hole 7 are formed in the same processing step; after the sheet body 1b is connected to the connecting copper busbar 3, the limiting portions 8 on both sides can also limit the sheet body 1b, thereby further improving the position stability of the sheet body 1b; at the same time, due to the large size of the stabilizing hole 7 and the bending portion 6, it is easier and simpler to insert the bending portion 6 into the stabilizing hole 7, which reduces the convenience of operation.

[0039] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
