Description

Technical Field

[0001] This utility model relates to the field of communication technology, specifically a photovoltaic inverter communication module. Background Technology

[0002] In photovoltaic inverter systems, the communication module plays a crucial role. It is responsible for transmitting data such as the inverter's operating status and fault information to the monitoring system or other control equipment to achieve remote monitoring and control. Currently, most photovoltaic inverter communication modules used in the industry adopt a design that combines board-side and wired components, and are usually installed on the enclosure.

[0003] However, in practical applications, this communication module has some problems that urgently need to be solved. Especially during the insertion process of the board-end and cable-end sections, due to factors such as machining tolerances, assembly tolerances, and vibrations and temperature changes during use, the cable ports on the board-end are easily subjected to force, leading to cable loosening. Loosening of the cable not only causes the cable port to shift backward but may also cause poor contact, thus affecting the connection effect of the communication module and the stable transmission of signals.

[0004] To address this issue, the industry has undertaken numerous attempts and explorations. Traditionally, fasteners such as open-end nuts are used to secure cables (e.g., Figure 8 and Figure 9 (As shown), however, this method often falls short in dealing with complex and ever-changing stress environments, making it difficult to effectively prevent cable loosening. Especially under extreme conditions, such as strong winds or earthquakes, the problem of cable loosening may be more serious, posing a serious threat to the reliability and stability of the communication module. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a photovoltaic inverter communication module that can fundamentally solve the problem of loose cables and ensure that the communication module can maintain a stable connection under various conditions.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A photovoltaic inverter communication module is characterized in that it includes an end plate portion and a line end portion, wherein the line end portion is detachably plugged into the end plate portion, the end plate portion includes a body, a communication cable is fixedly disposed inside the body, the outer end of the communication cable is provided with an end plate interface, the line end portion includes a line end interface, the inner end of the line end portion is plugged into the outer end of the body, the end plate interface is mated with the line end interface, the inner end of the body is threadedly connected with an anti-loosening nut, the inner end of the communication cable passes through the anti-loosening nut, and the anti-loosening nut is engaged with the outer side of the communication cable.

[0008] In a preferred embodiment, a rubber-coated body is fixedly disposed on the outside of the communication cable and inside the main body, and the inner end of the rubber-coated body is located on the outside of the inner surface of the anti-loosening nut.

[0009] In a preferred embodiment, the gap width between the inner end of the rubber-coated body and the inner surface of the anti-loosening nut is 0.2 mm.

[0010] In a preferred embodiment, a sealing ring is fixedly provided at the connection between the outer side of the main body and the wire end portion.

[0011] In a preferred embodiment, a step is provided in the middle of the body, and a sealing gasket is provided on the outer side of the body and on the inner side of the step.

[0012] In a preferred embodiment, the board end portion further includes a dust cover, which is inserted into the outer end of the board end portion when the wire end portion is not connected to the board end portion.

[0013] This utility model provides a communication module for a photovoltaic inverter. It has the following beneficial effects:

[0014] To prevent cable loosening: By introducing an anti-loosening nut and designing it with an internally enclosed structure, which is highly compatible with the rubber-coated body of the communication cable, the outward extension of the cable under force is effectively limited, thereby avoiding the problem of cable and port loosening. This design not only improves the durability of the communication module, but also ensures the stability and continuity of signal transmission.

[0015] Enhanced sealing performance: Sealing rings and gaskets are installed at the connection points of the communication module to further enhance the sealing performance. This helps prevent external factors such as moisture and dust from entering the communication module, protecting internal electronic components from damage, improving the waterproof performance and service life of the communication module, and the dust cover design also facilitates protection and dust prevention for users when the connection cable ends are not needed.

[0016] Optimized communication performance: Thanks to effective prevention of cable and port loosening and enhanced sealing performance, this communication module can transmit signals more stably, reduce signal loss and interference, thereby improving the clarity and accuracy of communication.

[0017] High adaptability: The design of this communication module is not only suitable for photovoltaic inverters, but can also be widely used in other occasions that require a stable communication connection, and has strong versatility and adaptability. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-7As shown, a photovoltaic inverter communication module includes a board-end portion 20 and a line-end portion 30, which are connected by a detachable plug-in method to ensure communication stability and reliability. The main body 202 serves as the main structure of the board-end portion 20, and a communication cable 205 is fixedly installed inside the main body 202. The communication cable 205 is responsible for transmitting signals, ensuring smooth communication between the photovoltaic inverter and other devices. A board-end interface 2051 is provided at the outer end of the communication cable 205 for docking with the line-end interface 301 of the line-end portion 30. To enhance the cable's stability, an insulated body 2052 is fixedly installed inside the main body 202 on the outer side of the communication cable 205. The insulated body 2052 not only increases the cable's rigidity but also provides protection. An anti-loosening nut 204 is threadedly connected to the inner end of the main body 202. The anti-loosening nut 204 is designed with an internally enclosed structure, and its overall height is adapted to the insulated body 2052 of the communication cable 205. After tightening, the gap width between the top inner surface 2041 of the anti-loosening nut 204 and the inner end side of the rubber-coated body 2052 is 0.2mm. This design restricts the rubber-coated body 2052 of the communication cable 205 from being pushed out when under force, thereby effectively preventing the communication cable 205 from loosening.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, a sealing ring 203 is fixedly installed at the connection between the outer side of the main body 202 and the wire end portion 30 to enhance the sealing performance of the connection. Meanwhile, a step is provided in the middle of the main body 202, and a sealing gasket 206 is provided on the inner side of the step to further improve the waterproof sealing effect.

[0031] like Figure 2 , Figure 4 and Figure 6 As shown, when the wire end portion 30 is not connected to the board end portion 20, the dust cover 201 is inserted into the outer end of the board end portion 20 to provide dust protection.

[0032] like Figure 6 and Figure 7 As shown, this utility model optimizes the structure and uses an anti-loosening nut 204 to replace the traditional open nut. In actual use, the plate end portion 20 is installed on the housing 10, and the housing 10 is located inside the step of the plate end portion 20. The anti-loosening nut 204 acts as a fiber to the inner end of the rubber-coated body 2052, which can prevent the rubber-coated body 2052 that restricts the communication cable 205 from being pushed out when under force.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
