Small wire-to-board connector with automotive quality

28 February 2022 Interconnection

Hirose Electric has developed the GT50 Series, a 1 mm pitch, small and robust wire-to-board connector. This product can be used safely for automotive applications due to its high heat resistance up to 125°C and robust design.

Owing to the shift to more electronics in vehicles due to technical innovations in EVs (electric vehicles) and autonomous driving, demand for wire-to-board connectors for the internal connection of automotive electronics has increased. With limited mounting space available in these applications, there is a particular need for smaller and lighter connectors. At the same time, resistance to heat generated from the high mounting density of electrical components and the high reliability required to withstand vibration during driving, are also essential. However, there are few existing connectors that meet these requirements and users are forced to choose from either large automotive connectors or smaller connectors used in consumer electronics which are not suitable for automotive applications.

In order to solve such issues, the GT50 was developed to achieve a small size with 1 mm pitch and 5,97 mm height. The applicable cable size is just 0,08 mm2, about 75% lighter than the 0,3 mm2 size cable that is often used for internal connection in automotive applications.

Although small in size, lances are provided on both the contacts and the housing to prevent the contacts from coming off, enabling high retention force during cable pulling. In addition, the GT50 series has sufficient locking strength and PCB peel strength to make it a robust connector for internal connection.

The heat-resistant material and design of the crimp contact ensure heat resistance up to 125°C. In addition, a stabiliser prevents the contact from moving inside the housing, providing high vibration resistance verified by vibration test results that confirm no changes in contact resistance. This product can be used in high-temperature environments as well as automotive devices that are subject to strong vibration.
