The ODU STAMPTAC - With ideal surfaces for all contact areas

The ODU STAMPTAC – With ideal surfaces for all contact areas
(PresseBox) ( Mühldorf, )
The stamped ODU STAMPTAC contact has been developed systematically over the past two years. It’s now available as 3 mm and 6 mm versions, ready for serial production and compliant with protection class IP67. What makes it so special: It delivers optimal results thanks to three different surface varieties for the crimp and contact areas as well as for the contact body – and all of it at a cost reduction of some 20 percent compared to previous turned contacts.

Mühldorf am Inn. The systematic development of its contact technology for eMobility has led ODU to stamped-turned contacts. They complement the existing and approved turning contacts very well. The ODU STAMPTAC is an economical stamped & formed contact that is automatable and suitable for mass production. It’s IEC standard-compliant and can be built into charger plugs for hybrid and plug-in vehicles. Along with the successfully introduced 3 mm version, it’s now also available as a 6 mm standard version. In the stamped slotted ODU STAMPTAC contact variety, the base body also serves as contact system. This means that no additional transmission element is required. The slotted fingers reliably connect with the contact pin – even after over 10,000 mating cycles. Moreover, the contact is still fully functional when mated at an angle of up to 5°.

Finished surfaces – tripartite

The latest development of the stamped & formed contact is its tripartite surface coating. The slotted contact fingers of the copper hollow body are silver-plated for better transmission. The crimping part, in contrast, is tin-coated – an ideal solution for crimping. The middle part is nickel-plated and corrosion-proof. These optimized surfaces enable the economical stamped ODU STAMPTAC contact to display the same properties as a turned contact system made of solid material.

Tight despite its hollow body

Tightness plays an important role in eMobility. After all, charging must be possible even in rain or snow. Instead of a so-called O-ring, as typically used in a turned body, silicon overmolding of the hollow body in the form of a three-lip seal now guarantees protection class IP67.

Turned or stamped

A great deal of contact technology is required for eMobility applications, and contacts are built into many different places of the vehicle. Therefore, they must meet high and varied requirements and challenges: vibration resistance, media resistance, low weight and contact security. The demand for economical interfaces is growing. Quick utilizability, suitability for serial production, automatable processing along with short delivery times are expected.

Until now, turned IEC 62196-1-compliant contacts were either successfully used as slotted contacts or as contacts with lamella technology. The ODU TURNTAC, ODU LAMTAC and ODU SPRINGTAC products stand out due to their great number of mating cycles, outstanding power transmission and particular ruggedness.

With the ODU STAMPTAC, ODU has developed an economical contact for large serial production, which is also almost on a par with turned contacts regarding de-rating: the stamped contact reaches the essential characteristics of a turned contact and the costs are some 20 percent lower than for solid material contacts. This can, of course, be an especially significant factor when it comes to high volumes. With the ODU STAMPTAC, ODU is ready and ideally positioned for serving a growing market – for all requirements.
