Products Description

Power Switch Copper Silver Riveted Contacts

Power Switch Copper Silver Riveted Contacts are high-performance electrical contacts designed for transfer switches in power systems. Made of copper-silver alloy material and combined with riveting technology, they have extremely high conductivity, wear resistance and oxidation resistance, ensuring stable operation under high-load and high-frequency switching conditions. The electrical contacts can effectively reduce contact resistance, improve current transmission efficiency, extend equipment life and reduce maintenance frequency.

Product Appearance Inspection

Dimensional Accuracy Verification

Ensuring the precise measurement of length, width, thickness, and riveted areas of Copper-Silver Riveted Electrical Contacts is essential for appearance inspection. Utilize advanced measuring instruments like calipers, micrometers, or height gauges to confirm that all dimensions fall within specified tolerances. Any dimensional inconsistency can lead to installation issues or impair the performance of the transfer switch, such as creating poor electrical contacts. Therefore, it is vital to maintain stringent control over these measurements.

Surface Flatness and Finish Assessment

Evaluate whether the surface of the Transfer Switch Copper Contact Rivet is smooth and level, free from visible bumps, scratches, or burrs. Irregularities on the surface can affect the contact area, reducing stability and increasing resistance. By using a combination of visual checks and tactile feedback, along with further examination using an optical microscope, any potential surface defects should be scrutinized to ensure optimal conductivity and durability.

Rivet Joint Inspection

Inspect the riveted connections for signs of proper bonding, ensuring the rivet is secure and shows no signs of loosening. The shape of the rivet head should be intact and uniform. Additionally, check the riveted area for cracks, deformation, or excess material that may have spilled over. A well-executed rivet joint is critical for maintaining the integrity and long-term reliability of the electrical contact, and any anomalies should be identified and addressed promptly.

Good Quality Depends on Advanced Testing Equipments

Hot riveting process

The hot riveting process of Power Switch Copper Silver Riveted Contacts can handle many different types of materials, whether it is between different metals or a combination of metals and plastics, it can achieve reliable connections. The hot riveting process is relatively simple to operate and can be efficiently completed with the help of automated equipment in large-scale production.

High connection strength:

After heating, the plasticity of the rivet increases, the hardness decreases, the nail head is easy to form, and the external force required is much smaller than that of cold riveting.

Applicable to a variety of materials:

It can connect materials of different materials such as metal and metal, metal and plastic, plastic and plastic, and can make full use of the mechanical properties of various materials.

Simple and efficient process:

The hot riveting process is relatively simple and easy to operate. It does not require complex equipment and technology and is easy to master and apply.

Manual riveting and automatic drilling and riveting

Manual riveting

Manual riveting is a traditional riveting method that mainly relies on the manual operation of workers. In the manual riveting process, the worker first inserts the rivet into the pre-drilled workpiece hole. Then, use a tool such as a rivet gun or a hammer to apply pressure to one end of the rivet. If a rivet gun is used, the punch of the rivet gun is driven by a power source such as compressed air to impact the rivet and deform it; if a hammer is used, it depends on the worker's knocking force.

Automatic drilling and riveting

Automatic drilling and riveting is an advanced machining technology that integrates the two processes of drilling and riveting and realizes automated operation. In the automatic drilling and riveting system, the workpiece is first accurately fixed on the workbench by a high-precision positioning device. Then, the drilling and riveting equipment automatically drills the workpiece according to the preset program, and the depth, diameter and position of the drilling can be precisely controlled.
