This automotive male connector has superior comprehensive electrical characteristics, supporting multi-range nominal voltage architecture covering 12V, 24V and 48V, fully compatible with passenger vehicles, commercial vehicles, new energy vehicles and various engineering machinery low-voltage and medium-voltage power supply systems. The maximum safe operating voltage can reach 60 VDC, which can stably bear long-term continuous power supply of vehicle power distribution modules and high-power electrical accessories. Equipped with high-quality conductive male tab terminals, the maximum contact current rating can reach 30A, which can steadily support high-current automotive electrical equipment, power drive components and on-board heavy-load circuit operation. The internal conductive structure has ultra-low contact resistance, good thermal conductivity, no heating, no power loss, ensuring continuous, safe and stable electrical transmission without overload burnout and leakage risks.

4. Body Features

The connector main body is made of high-strength industrial PBT GF30 glass fiber reinforced engineering plastic material, with high hardness, strong compression resistance, impact resistance, cracking resistance and permanent anti-aging performance. The primary product color is classic industrial black, which is dirt-resistant, oil-resistant and not easy to fade and yellow after long-term outdoor and under-hood use. It supports dual cable exit angles of 90° and 180°, which can flexibly adapt to different vehicle wiring space layouts, avoid sharp bending and extrusion damage of wire harnesses, and optimize on-site wiring routes. The connector is designed with keying code A, which plays a foolproof anti-misplug role to prevent wrong assembly and reverse connection of circuits. The overall shell has excellent oil corrosion resistance, dust erosion resistance and temperature alternation resistance, and can maintain stable structural performance in all harsh vehicle environments for a long time.

5. Contact Features

Matched with high-precision standard tab-type male contacts, the professional contact size is 2.8mm, and the precise mating tab width is also controlled at 2.8mm, ensuring accurate alignment, tight fitting and seamless docking with supporting female terminals. The male tab contacts are made of high-purity high-conductivity copper alloy with anti-oxidation electroplated surface, which can resist humid environment, dust corrosion and long-term high-temperature baking, and always maintain stable conductive performance. The contact structure has high rigidity and is not easy to bend and deform after repeated plugging and unplugging. Cooperating with terminal self-locking design, it can effectively resist vibration and shaking during vehicle driving, prevent virtual connection, power failure and poor contact faults, and ensure uninterrupted stable current output of automotive power circuits all year round.

6. Dimensions

Produced by high-precision professional automotive molds, all dimensions are strictly in line with industry standard specifications. The connector height is 48.1mm, product length is 40.6mm, and product width is 27mm, with reasonable overall structure and strong three-dimensional stability, suitable for installation in vehicle chassis, electrical boxes and engine peripheral fixed positions. A variety of row-to-row spacing options are available to meet different harness assembly requirements. The centerline pitch is 6mm with high precision and strong interchangeability. The overall size is fully compatible with mainstream matching accessories on the market, no need to modify assembly fixtures and molds, directly replace and install, effectively saving production line adjustment time and enterprise procurement costs.

7. Usage Conditions

This heavy-duty automotive connector has ultra-wide temperature environmental adaptability, with an operating temperature range of -40°C to 140°C, and the maximum resistant temperature can reach 140°C. It can resist severe cold frost in alpine regions, and also withstand long-term high-temperature heat radiation near automobile engines, without shell brittleness, aging and terminal failure.
