Press-Welded Connectors
In the conductive circuits of power distribution systems, energy storage modules and heavy industrial equipment, connection points are often the source of system thermal failure and energy loss. Press-Welded Connectors provide a third-generation connection technology that is different from traditional bolt fastening or pure friction contact - using the principle of controllable solid-state welding to achieve atomic-level fitting of conductor interfaces with the assistance of pressure to build low-impedance, creep-resistant, maintenance-free electrical connections.

Product Introduction
Press-Welded Connectors are not a simple mechanical compression, but a precisely controlled axial pressure is applied through special tooling, causing controllable plastic deformation at the interface between the connector and the connected conductor (copper bar, aluminum bar or plated conductor), breaking the surface oxide film of several microns, and forming a continuous solid bonding layer in which metal bonds are embedded in each other.
core features
Flexible Bus Bars are precision mechanical and electrical integrated components that have four core properties: "zero thermal stress installation, airtight connection, high mechanical retention, and long-term stability."
Solder-free metallurgical connection
Abandoning soldering and flux, relying on atomic-level bonding caused by elastic deformation of metal to form an air-tight cold welding joint, eliminating the risks of false soldering, desoldering, tin whisker growth and flux residue from the source for Copper Foil Bus Bar.
01
Elastic adaptive structure
Using special elastic alloy pins, the plastic deformation can be controlled during crimping, automatically adapting to the micron-level tolerance of the PCB hole diameter, while providing continuous radial pressure to ensure long-term stability of the connection.
02
Mechatronics reliability
It has both excellent electrical performance and mechanical strength. The contact resistance is stable at the milliohm level. It can withstand multiple plugging and unplugging and severe vibration. The connection life is far longer than that of traditional welding nodes for Flexible Bus Bar.
03
Strong environmental adaptability
The entire series meets RoHS environmental protection requirements, with an operating temperature range of - 55°C to + 125°C, and can operate stably for a long time in harsh industrial environments such as humidity, salt spray, and dust for Copper Foil Connector.
04
Detailed display
Inner hole surface texture
We use a fine reaming or polishing process with roughness Ra ≤ 1.6μm instead of a rough turning surface to ensure uniform deformation during pressure welding for Copper Foil Bus Bar.
Introduction chamfer
Set a 30° guide chamfer to avoid scratches on the metal wire or burrs during conductor installation for Flexible Busbars for Battery Connector.
Pressure welding mark inspection area
The outer wall of the connector is designed with a tiny observation slot or marking position, which can be used to visually confirm the effective pressure welding length.
Batch laser traceability code
Each batch of connectors is engraved with a process traceability code, which can be traced back to the raw material heat number, processing shift and press parameters for Copper Foil Connector.
Application scenarios
Rail transit and high-speed rail
Used for jumper cables between carriages, pantograph connections and braking system lines. Its anti-vibration properties perfectly comply with EN 45545 fire and smoke toxicity standards for Copper Foil Multi-Layer Welding Busbar.
Photovoltaic and energy storage system (ESS)
Provides low-impedance high-current connections between the combiner box, inverter and battery cluster to reduce energy loss on the DC side and improve the overall system efficiency.
Mining and heavy machinery
In the face of dust, moisture and severe impact, the sealing performance of pressure welding connectors ensures the continuous operation of equipment under abnormal working conditions for Copper Laminated Flexible Connectors.
Data centers and UPS
Provide reliable bus connections for high-power PDUs and backup power supplies, reducing the contribution of cable losses to PUE values for Copper Foil Flexible Storage Energy Battery Busbar.
