Description

Technical Field

[0001] This application relates to the field of harmonic suppression equipment technology, and in particular to a cable connector used in harmonic suppressors. Background Technology

[0002] In power transmission systems, the fundamental frequency is a sinusoidal wave under ideal transmission conditions, with a frequency of 50Hz. When a line fault or a large number of nonlinear loads occur in the circuit, the fundamental frequency may be distorted into a higher-order sinusoidal wave that is a positive integer multiple of the original frequency, i.e., harmonics (second harmonic, third harmonic, etc.). The presence of harmonics reduces the stability of the power grid system and increases power losses; for electrical equipment in the power grid, it shortens the service life of the equipment and may even cause damage.

[0003] A harmonic suppressor is an electrical device commonly used in circuit systems. After being connected to the power grid, it can attenuate harmonics to an acceptable range. The core of a harmonic suppressor is a special resistor that absorbs harmonic energy and converts it into heat energy, thereby improving the stability of the power grid system and related electrical equipment.

[0004] The installation process of the harmonic suppressor is roughly as follows: First, install conductive terminals (such as copper terminals, aluminum terminals, etc.) at the end of the cable. The conductive terminals have circular through holes. Then, put the conductive terminals through the circular through holes onto the terminal block at the top of the harmonic suppressor. Finally, install nuts on the terminal blocks so that the nuts press the conductive terminals together, thus completing the installation of the harmonic suppressor (the grounding and positioning operations of the harmonic suppressor are not described here).

[0005] Because different conductive terminals have different specifications, the inner diameter of the through holes on different specifications of conductive terminals is also different. The terminals on the harmonic suppressor are difficult to adapt to conductive terminals of different specifications, so the conductive terminals need to be replaced. Therefore, the compatibility between conductive terminals and harmonic suppressors needs to be further improved. Summary of the Invention

[0006] To improve the compatibility between harmonic suppressors and conductive terminals of different specifications, this application provides a cable connector for use with harmonic suppressors.

[0007] This application provides a cable connector for use in a harmonic suppressor, employing the following technical solution:

[0008] A cable connector for use in a harmonic suppressor includes a connector shaft disposed on the harmonic suppressor, wherein the connector shaft and the terminal block on the harmonic suppressor are electrically conductive to each other, the connector shaft is provided with a plurality of wiring positions for fitting conductive terminals, and the outer diameter of the plurality of wiring positions increases sequentially from one end of the connector shaft to the other end of the connector shaft.

[0009] With the above technical solution, when the operator needs to connect the harmonic suppressor to the circuit system, firstly, the conductive terminal is installed at the end of the cable in the circuit system so that the conductive terminal and the cable can conduct electricity to each other; then, the connector is installed on the terminal block on the harmonic suppressor so that the connector and the terminal block of the harmonic suppressor can conduct electricity to each other; next, the conductive terminal is fitted along the smaller outer diameter end of the connector on the connector to the larger outer diameter end so that the connector is inserted into the through hole of the conductive terminal.

[0010] If the inner diameter of the through hole on the conductive terminal is equal to the outer diameter of the wiring position at the top of the connector, then the remaining wiring and installation operations can be carried out directly.

[0011] If the inner diameter of the through hole on the conductive terminal is larger than the outer diameter of the wiring position at the top of the connector, the operator can continue to slide the conductive terminal downwards until the inner diameter of the through hole on the conductive terminal matches the outer diameter of a wiring position on the connector. At this point, the inner wall of the through hole of the conductive terminal and the outer wall of the wiring position will fit together.

[0012] Therefore, by setting several wiring positions with sequentially changing outer diameters on the wiring shaft, this application enables the inner wall of the through hole on the terminal block to fit into the outer wall of a certain wiring position, thereby improving the compatibility between the harmonic suppressor and conductive terminals of different specifications.

[0013] In a preferred embodiment, this application can be further configured such that: the wiring shaft is provided with a plurality of connecting parts, and the plurality of connecting parts and the plurality of wiring stations are alternately distributed in sequence;

[0014] The outer diameter of any of the connecting parts gradually increases from one end of the wiring shaft to the other end of the wiring shaft, and the direction of the increase of the radius of the connecting part is consistent with the direction of the increase of the radius of the plurality of wiring stations.

[0015] With the above technical solution, since each connection part is located between two wiring stations and the radius of the connection part gradually increases, the possibility of the conductive terminal being obstructed by the end of the wiring station is reduced during the process of the conductive terminal moving along the direction of increasing radius of the wiring station, thereby improving the smoothness of the conductive terminal movement.

[0016] In a preferred embodiment, this application can be further configured such that: both ends of the connecting part are provided with connecting rods, and the end of the wiring station is provided with a connecting hole for inserting the connecting rod, and the connecting rod and the inner wall of the connecting hole are threaded together.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] This application improves the compatibility between the harmonic suppressor and conductive terminals of different specifications by setting several wiring positions with sequentially changing outer diameters on the wiring shaft, so that the inner wall of the through hole of the wiring terminal and the outer wall of a certain wiring position fit together.

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.

[0024] This application discloses a cable connector used in a harmonic suppressor.

[0025] See attached document Figure 1 and attached Figure 2 As shown, a cable connector for a harmonic suppressor includes a shaft 1 for mounting conductive terminals 201 on a circuit system cable. The shaft 1 is mounted on a terminal 21 of the harmonic suppressor 2, and the shaft 1 is vertically positioned so that the shaft 1 and the terminal 21 of the harmonic suppressor 2 can conduct electricity to each other.

[0026] See attached document Figure 1 and attached Figure 2 As shown, the wiring shaft 1 is provided with several wiring stations 11 and several connecting parts 12, which are arranged alternately from top to bottom.

[0027] See attached document Figure 1 and attached Figure 2 As shown, each wiring station 11 is cylindrical, and the outer diameter of several wiring stations 11 increases sequentially from top to bottom; each connecting part 12 is frustum-shaped, and the outer diameter of each connecting part 12 gradually increases from top to bottom. The axis of the connecting part 12 and the axis of the wiring station 11 are collinear, and the outer diameter of the top end of any connecting part 12 is equal to the outer diameter of the adjacent wiring station 11 above it, and the outer diameter of the bottom end of any connecting part 12 is equal to the outer diameter of the adjacent wiring station 11 below it.

[0028] When the operator needs to connect the harmonic suppressor 2 to the circuit system, first install the conductive terminal 201 on the end of the cable in the circuit system so that the conductive terminal 201 and the cable can conduct electricity to each other; then, install the connector 1 on the terminal 21 on the harmonic suppressor 2 so that the connector 1 and the terminal 21 of the harmonic suppressor 2 can conduct electricity to each other; then, from top to bottom, put the conductive terminal 201 on the connector 1 so that the connector 1 is inserted into the through hole of the conductive terminal 201.

[0029] If the inner diameter of the through hole on the conductive terminal 201 is equal to the outer diameter of the wiring station 11 at the top of the connector 1, then the remaining wiring and installation operations can be performed directly. If the inner diameter of the through hole on the conductive terminal 201 is greater than the outer diameter of the wiring station 11 at the top of the connector 1, then the operator can continue to slide the conductive terminal 201 downwards until the inner diameter of the through hole on the conductive terminal 201 matches the outer diameter of a certain wiring station 11 on the connector 1. At this time, the inner wall of the through hole of the conductive terminal 201 and the outer wall of the wiring station 11 are in contact with each other.

[0030] Therefore, conductive terminals 201 of different specifications can be installed on different wiring positions 11 of the wiring shaft 1, thereby improving the compatibility between the harmonic suppressor 2 and conductive terminals 201 of different specifications.

[0031] See attached document Figure 1 and attached Figure 2 As shown, each connecting part 12 has a connecting rod 121 at both ends. The connecting rod 121 and the connecting part 12 are integrally formed, and the axis of the connecting rod 121 and the axis of the connecting part 12 are collinear. A connecting hole 111 is provided at the end of the wiring station 11 for inserting the connecting rod 121, which is threaded into the inner wall of the connecting hole 111. By changing the wiring station 11 with different outer diameters, the operator can expand the applicability of the wiring shaft 1.

[0032] The implementation principle of this embodiment is as follows: The cable connector in this application sets a number of wiring positions 11 with sequentially changing outer diameters on the wiring shaft 1, so that the inner wall of the through hole of the wiring terminal and the outer wall of a certain wiring position 11 fit together, thereby improving the compatibility between the harmonic suppressor 2 and conductive terminals 201 of different specifications.

[0033] The embodiments described in this specific implementation are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
