Description

Technical Field

[0001] The invention relates to the technical field of wiring terminals, and in particular to a self-locking wiring port of a harmonic suppression compensation module. Background Art

[0002] Harmonics are a series of sinusoidal waves whose frequencies are integer multiples of the fundamental wave. In this series of sinusoidal waves, there are countless frequency waves with different frequencies and amplitudes. These sinusoidal waves will cause asymmetry of sinusoidal current and voltage in the power system, causing very serious harm to the system.

[0003] Harmonic suppression is a technology that suppresses the influence of harmonics based on the causes of harmonic generation. In an ideal clean power supply system, both current and voltage are sinusoidal. In a simple circuit containing only linear elements (resistance, inductance and capacitance), the current flowing is proportional to the applied voltage, and the current flowing is a sine wave. With the continuous advancement and development of power electronics technology, power electronic equipment in the system has been widely used. At the same time, nonlinear loads are increasing, and high-voltage direct current power is popularized, resulting in increasingly serious harmonic problems in power systems. Therefore, it is necessary to propose various technologies for suppressing harmonics and the suppression effect based on the causes of harmonic generation. In the existing technical means, a harmonic suppression module is usually used to suppress harmonics. Therefore, when using the wiring port of the harmonic suppression module, it is found that the connection wire of the wiring port is often easy to disconnect by itself, and if the connection wire is welded, it will cause trouble for later replacement and maintenance. For this reason, we propose a self-locking wiring port for harmonic suppression compensation module. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a self-locking wiring port for a harmonic suppression compensation module, which has the advantages of convenient replacement of wires and preventing them from falling off, thus solving the problem of frequent falling off of connections in existing devices.

[0005] The self-locking wiring port of the harmonic suppression compensation module of the present invention comprises a suppression module, wherein a plurality of wiring ports are provided on the front of the suppression module, a fixed block is fixedly connected inside the wiring port, a data connection line is fixedly connected to the bottom of the fixed block, one end of the data connection line is fixedly connected to an interface fixing seat, a wiring port A is fixedly connected to the left side of the interface fixing seat, a hollow cylinder is sleeved inside the interface fixing seat, two groups of strip grooves are provided inside the hollow cylinder, two groups of sliders are slidably connected at the strip grooves of the hollow cylinder, and the two groups of sliders are far away from each other, a self-locking spring is fixedly connected between the two groups of sliders, the outer sides of the two groups of sliders are fixedly connected to limit rods, and the inner cavity of the wiring port is provided with two groups of No. 1 limit holes and No. 2 limit holes, and the two groups of No. 1 limit holes and No. 2 limit holes are far away from each other.

[0006] The self-locking wiring port of the harmonic suppression compensation module of the present invention has two groups of strip-shaped sliding grooves on its inner wall, and the strip-shaped sliding grooves of the wiring port are slidably connected with the hollow cylinder.

[0007] The self-locking wiring port of the harmonic suppression compensation module of the present invention has a connecting line fixedly connected to the left side of the hollow cylinder, a wiring B port fixedly connected to the right side of the connecting line, and the hollow cylinder and the wiring B port are sleeved and connected.

[0008] The self-locking wiring port of the harmonic suppression compensation module of the present invention has a wiring port A that is compatible with a wiring port B, and a compression spring is sleeved on the right side of the wiring port A.

[0009] The self-locking wiring port of the harmonic suppression compensation module of the present invention has two groups of connection seats fixedly connected to the top of the suppression module, and a connection base plate fixedly connected to the bottom of the connection seat.

[0010] The self-locking wiring port of the harmonic suppression compensation module of the present invention has two groups of threaded through holes on the top of the connecting base plate, bolts are threadedly connected to the threaded through holes of the connecting base plate, and the two groups of threaded through holes are far away from each other.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present invention enables the connection line to be connected to the connection port through the hollow cylinder by cooperating the connection line A port with the connection line B port. Because the hollow cylinder is provided, a self-locking operation can be performed when the connection line is matched with the connection port to prevent disconnection. Furthermore, through the action of two sets of limit rods, when the device is self-locked, the connection line A port and the connection line B port can be stably connected and matched. When the connection needs to be disconnected, the limit rod can be pressed in, and through the action of the self-locking spring, the connection line A port and the connection line B port can be smoothly disconnected, so as to be replaced.

[0013] 2. The present invention uses a slider and a self-locking spring in the hollow cylinder so that when the limit rod slides to the No. 1 limit hole and the No. 2 limit hole in the hollow cylinder, it can be popped out by the self-locking spring, so that the connection between the wiring port A and the wiring port B can be fixed, thereby achieving the purpose of preventing falling off. Through the cooperation of the two groups of limit holes, the connection is avoided due to external reasons when the port is connected, and the need for replacement is convenient after self-locking.
