Description

Technical Field

[0001] This utility model relates to the technical field of RC resistor-capacitor absorption devices, specifically a novel RC resistor-capacitor device. Background Technology

[0002] RC devices are mainly used in power generation, power supply, and industrial power systems to limit operational overvoltages in the power system, preventing insulation damage to electrical equipment caused by operational overvoltages. However, current overvoltage protectors have the following drawbacks:

[0003] Resistor-capacitor (RC) devices are frequency-sensitive components. In recent years, due to the widespread use of frequency converters, the high-frequency harmonic components in the power grid have increased significantly. In the past, RC devices were either fully encapsulated or unencapsulated, and they often suffered from failures such as breakdown, burnout, and explosion.

[0004] Therefore, we propose a novel RC resistor-capacitor device to solve the above problems. Summary of the Invention

[0005] Purpose of the utility model: The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a new type of RC resistor-capacitor device.

[0006] Technical solution: The present invention discloses a novel RC resistor-capacitor device, comprising an outer shell and an inner shell connected to each other. A circuit board is installed inside the inner shell, and resistors and capacitors are installed on the circuit board. A lead-out structure is connected to the circuit board, and the other end of the lead-out structure extends out of the outer shell.

[0007] In some embodiments, the outer shell and the inner shell are connected by snap-fit.

[0008] In some embodiments, guide rails are provided on both sides of the outer side of the inner housing.

[0009] In some embodiments, potting compound is filled into the inner housing for sealing and insulation.

[0010] In some embodiments, the lead-out structure uses lead-out wires.

[0011] In some embodiments, the lead wire is adapted to connect to a terminal block on the housing.

[0012] In some implementations, the lead-out structure uses a socket and a pin.

[0013] In some embodiments, the outer casing is provided with multiple through holes.

[0014] Beneficial effects: The beneficial effects of this utility model are as follows:

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "inner", "outer", etc., which indicate the orientation or positional relationship shown, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. Example

[0026] like Figure 1 and Figure 2 As shown, a novel RC device includes an outer shell 1 and an inner shell 2 connected to each other. A circuit board 5 is installed inside the inner shell 2. A resistor 3 and a capacitor 4 are installed on the circuit board 5. A lead-out structure is connected to the circuit board 5, and the other end of the lead-out structure extends to the outside of the outer shell 2.

[0027] In this embodiment, as Figure 2 and Figure 3 As shown, the lead-out structure uses lead wires 6, and three lead wires 6 are soldered to the circuit board 5. The three lead wires 6 are filled with potting compound inside the inner housing 2 along with the soldered circuit board 5 to seal and insulate the pins and pads. The outer housing 1 is also provided with three through holes for leading the lead wires 6 on the circuit board 5 to the outside of the outer housing 1. Example

[0028] This embodiment is based on the previous embodiment. Three terminals can be directly set on the outer casing 1. The terminals run through the inside and outside of the outer casing. The lead wires 6 on the circuit board 5 can be crimped to the terminals on the inside of the outer casing 1. In this way, when using the device, the user only needs to connect the terminals on the outside of the outer casing with an insulated wire, which is also convenient for transportation. Example

[0029] like Figure 4 As shown, this embodiment is based on the previous embodiment, and the socket and pin 7 can be directly installed on the outer casing 1. Three round sockets are provided on the outer casing 1, which penetrate through the inside and outside of the outer casing. The outer end is for the user to plug in the lead wire, and the inner end is adapted to connect to the pin 7.

[0030] In addition, such as Figure 4 As shown, the inner shell 2 has a protruding buckle 22 on its outside, the outer shell 1 has a slot for connecting and fixing with the inner shell, and finally a bottom sealing plate is installed on the bottom surface of the outer shell 1.

[0031] In addition, such as Figure 4 As shown, the inner walls on both sides of the outer shell 1 are also provided with guide grooves for positioning. The outer sides of the inner shell 2 are provided with guide rails 21. The tail of the inner shell 2 is integrated with the bottom sealing plate in Embodiment 1. In this way, the RC resistor-capacitor device can form a unit inside. The unit can be directly inserted into the outer shell 1 to complete the installation. This method makes installation and disassembly very convenient and the process is simple.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
