Compact Low-Profile Heavy Duty Connector HDC-HQ Series
While pursuing compact size, the HQ series further compresses the overall thickness of the connector and panel footprint, showing an ultra-flat or square compact form. The hoods & housings are mostly made of die-cast zinc alloy, maintaining IP65 / IP67 protection rating. Internally, it offers basic pin numbers such as 3-pin and 10-pin, with a highly integrated insert design. The insert structure is highly integrated, and the wiring method is generally connected by crimp connection., requiring the crimp wiring clamp tool to cooperate with the wire connection. The HQ series is especially suitable for lifting consoles, portable instrument cases, electric motorcycles, forklift battery interfaces, and thin-walled chassis installations, delivering industrial-grade durability in limited spaces.
Balance between space optimization and industrial performance: Compact Low-Profile Heavy Duty Connector HDC-HQ Series Applications
The core features of the HQ series are its high-density inserts and Slim-line housing design. Unlike standard HE or HA series connectors, Compact Low-Profile Heavy Duty Connector HDC-HQ Series achieves extremely high rated current in a very small space by optimizing the contact arrangement. This makes it an ideal choice for ‘thin-wall’ installation, as the case depth or external clearance is strictly limited in these applications.
Electric Motorcycle and E-mobility Power Interface
The electric mobility (E-mobility) industry needs components that can withstand high frequency vibrations, frequent insertion cycles, and high current loads. Compact Low-Profile Heavy Duty Connector HDC-HQ Series is often used as the main battery interface of electric motorcycles.
Vibration resistance: Its safety locking mechanism can prevent accidental disconnection during high-speed driving.
Thermal management: Despite its small size, HQ inserts (such as HQ-005 or HQ-012) are engineered to handle high ampere power transmission without overheating.
Forklift Battery Interfaces
Industrial material handling equipment (such as electric forklifts and AGVs) operate in harsh 24 / 7 environments. The HQ series can be used as a robust charging interface, and its Low-Profile design ensures that the connector does not over-protrude from the vehicle body, thereby reducing the risk of mechanical impact or hanging in a narrow warehouse channel.
Lifting Consoles and Ergonomic Control Stations
In heavy machinery and theatre stage equipment, the lifting console must be portable and streamlined in appearance. The Compact Low-Profile Heavy Duty Connector HDC-HQ Series allows the integration of multi-pin signals and power supplies in the slender handles or soleplates of the console. This ensures that the operation interface is light and easy to control, while still maintaining the protection level of IP65 or IP67.
Portable Instrument Cases and Field Equipment
Field technicians rely on portable diagnostic and testing equipment, which must withstand harsh outdoor conditions. By integrating the space-saving industrial connectors of the HQ series, manufacturers can reduce the overall size of the equipment box to make it truly ‘portable’ without sacrificing the ‘Heavy-duty’ protection required for field use.
Thin-walled Chassis and Modular Electronic Equipment
In order to save the area of the smart factory, modern control cabinets are becoming thinner and thinner. Compact Low-Profile Heavy Duty Connector HDC-HQ Series is designed for thin-walled chassis installation. Its reduced installation depth ensures that the internal wiring will not be squeezed or stressed, thus achieving a cleaner and more modular internal layout.
