Communication Module Cable Port Relocation for Inverter Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication modules in photovoltaic inverters face difficulties in facilitating the disassembly and assembly of network cables due to the rubber plug being difficult to remove, leading to blind insertion and complex cable handling within a limited internal space.
Innovation Solution
A communication module with a locking member comprising a tightening cap, clamping grip, and rubber plug, along with an intermediate connection pipe, allows for easy passage of the network cable and visible network cable port, enabling clear operation and assembly by relocating the network cable port to the housing end, and incorporating a waterproof washer for enhanced sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rubber plug is squeezed inside the housing to achieve waterproof effect, then the waterproof sealing is improved, but the disassembly and assembly of the network cable becomes difficult
Solution Approach 1:
The locking member is divided into separate components: the tightening cap, clamping grip, and rubber plug. This segmentation allows the rubber plug to be easily removed from the clamping grip after assembly, enabling cable replacement while maintaining waterproof sealing during operation.
Solution Approach 2:
The clamping grip is designed with flexible clamping jaws that can be dynamically adjusted by the tightening cap. When the tightening cap is rotated, it compresses the clamping grip to clamp the rubber plug securely. During disassembly, the clamping grip can be removed from the housing, allowing easy access to the rubber plug for replacement.
2Reliability
If the network cable port extends deep into the housing body, then the cable connection is secured, but the cable port location becomes invisible and hard to access
Solution Approach 1:
The locking member acts as an intermediary component that bridges the housing and the network cable. It provides a standardized interface with a passage for cable passage, allowing the cable to be securely connected without requiring direct access to the deep interior of the housing.
Solution Approach 2:
The locking member is pre-assembled with the rubber plug and clamping grip before installation. This preliminary preparation ensures that all necessary components are in place, and the cable port is properly positioned and visible before the actual cable connection operation.
3Volume of moving object
If the internal space of the communication module is limited, then the module size is compact, but the hand cannot reach in for operation
Solution Approach 1:
The locking member is designed as a separable assembly that can be removed as a unit from the housing. This allows maintenance operations to be performed on the cable connection without requiring hand access to the limited internal space of the communication module.
Solution Approach 2:
The components are nested within each other: the rubber plug is sleeved on the network cable, the clamping grip is sleeved on the rubber plug, and the tightening cap is sleeved on the clamping grip. This nested structure allows all components to be assembled in a compact manner while maintaining accessibility during assembly and disassembly operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies the assembly and disassembly of network cables by providing a clear connection point and easy access, reducing the complexity of cable handling and ensuring waterproof integrity.
Implementation Method 1
The rubber plug is sleeved on an outside of the network cable and clamps the network cable
Implementation Method 2
The tightening cap is sleeved on an outside of the clamping grip and is configured to compress clamping jaws of the clamping grip to clamp the rubber plug
Implementation Method 3
One end of the intermediate connection pipe is in threaded connection with the housing outside the wiring opening. The other end of the intermediate connection pipe is in threaded connection with the tightening cap

AI summary
The present disclosure provides a communication module and an inverter. The communication module includes a housing, a network cable port, and a locking member for blocking a wiring opening position at an end of the housing. The network cable port is located at the wiring opening position of the housing. The locking member is provided with a passage for a network cable to pass through. When the communication module needs to be assembled, the network cable passes through the locking member and is inserted into the network cable port. In this communication module, the network cable port is moved to the end of the housing, so that the network cable port can be clearly seen after the locking member is removed, thereby avoiding blind insertion of the network cable and facilitating the disassembly and assembly of the network cable.
