Description

Technical Field

[0001] This invention relates to the field of cable connector technology, specifically to a modular cable connector scalable interface device. Background Technology

[0002] Cable connectors are fundamental components in power transmission and signal communication. With the increasing integration of equipment functions, a single interface often cannot meet the needs of simultaneous connection of multiple signals and power supplies. Traditional cable connectors are mostly designed with fixed interfaces, where the number, type, and electrical parameters of the interfaces are determined during production. They cannot be flexibly expanded or changed according to field requirements. When additional functional modules (such as sensing, monitoring, backup power, etc.) are needed, the entire connector usually needs to be replaced, resulting in complex wiring, large space occupation, and high cost. Furthermore, signal routing needs to be reconfigured after expansion, and there is a lack of intelligent identification and status monitoring functions, resulting in insufficient flexibility and reliability in expansion. In addition, their locking structures are mostly ordinary threads or snaps, which are prone to loosening in vibration environments and have unstable contact resistance. Therefore, there is an urgent need to provide a modular cable connector expandable interface device. Summary of the Invention

Figure 1 , Figure 2 , Figure 4 and Figure 5 The locking component 200 is positioned corresponding to the mechanical interface 110, provides locking force, and connects the mechanical interface 110 and the connecting component 300. The locking assembly 200 includes an elastic clamp 210 connected to the top of the resin module 100. The top of the elastic clamp 210 is integrally formed in a cross shape with multiple sets of elastic flaps 211, forming a receiving space between them.

When the adjusting nut 220 is tightened, its inner conical surface forces the multiple sets of elastic flaps 211 to contract radially synchronously, uniformly clamping the inserted electrical connector 310. When the adjusting nut is loosened in the opposite direction, the elastic flaps 211 elastically reset, releasing the connector. This locking method has strong vibration resistance and stable contact resistance. Please continue reading.

The configuration management module is used to dynamically configure the signal routing and power distribution between the extended resin module interface 120 and the mechanical interface 110 according to the identification result of the central processing unit 411. The status monitoring unit 422 is used to monitor the operating status of resin module 100 and extended resin module interface 120 in real time, including temperature, humidity and connection reliability (including temperature (by built-in temperature sensor), humidity (by humidity sensor) and connection reliability (by detecting changes in contact resistance), and to issue an early warning when the parameters exceed the threshold). The cascade expansion module 423 is used to allow the extended resin module interface 110 and the mechanical interface 110 to be connected in series to form a multi-functional interface array with a chain or star topology. Working principle: In use, the electrical connector 310 is inserted into the mechanical interface 110 on top of the resin module 100, and the adjusting nut 220 is tightened. The elastic flap 211 clamps the connector, completing the mechanical and electrical connection.
