① Standard IP67 Version (Mainstream General Model):
It withstands water pressure of 0.01 MPa (1 meter water depth under normal pressure) with continuous immersion for 30 minutes. No water seepage or water ingress occurs. It is suitable for conventional waterproof scenarios such as car door wiring, vehicle body harnesses, headlight assemblies and ordinary outdoor equipment.
② Heavy-Duty IP68 Deep Waterproof Version (High-End Model):
It continuously resists 0.05 MPa water pressure (5 meters water depth) for 48 hours of long-term immersion without water penetration. It can temporarily withstand an extreme water pressure of 0.1 MPa (10 meters water depth). This variant fits harsh working conditions including chassis wiring harnesses, underwater sensors, deep-water outdoor equipment and wading components for new energy vehicles.
All waterproof performance data has passed third-party standardized testing, with measurable and verifiable test results for acceptance inspection.
Standard IP67 and IP68 ratings apply to static immersion conditions. For machine tools, automotive chassis, sanitation machinery and other equipment requiring high-temperature and high-pressure jet washing, we offer an upgraded IP6K9K high-pressure waterproof option.This version stands up to 80bar high-pressure water jet spray, with excellent heat resistance and anti-scour performance. It effectively prevents water ingress and short circuits caused by regular equipment cleaning or heavy rain exposure outdoors. Our product lineup covers both static underwater soaking and dynamic high-pressure flushing application scenarios.
This connector adopts dual protection with structural sealing plus rubber gaskets, which is far more reliable than products with only a single rubber ring. The housing is constructed with precisely interlocked sealing structure and independent sealed compartments to avoid water cross-leakage and seepage. The sealing gaskets are made of special EPDM rubber featuring ageing resistance, oil resistance and wide temperature adaptability from -40℃ to 120℃. They will not harden, deform or age easily under long-term immersion, temperature alternation and oily conditions, maintaining stable waterproof performance permanently and solving the common problems of ordinary rubber rings including premature ageing, cracking and water leakage.
All sealed automotive and industrial connectors are equipped with UL94 V-0 flame retardancy at a standard wall thickness of 1.6mm in strict accordance with UL safety standards. In the flammability test, samples self-extinguish rapidly within 10 seconds of single ignition, with no flaming drips or sustained smoldering, completely eliminating the risk of molten droplets igniting adjacent wiring harnesses and plastic components. Low-cost generic connectors on the market are mostly rated V-2 or non-flame-retardant, and produce burning drips that create severe fire hazards under high-temperature working conditions. Our products are manufactured with modified flame-retardant PA66+GF30 and PBT with glass fiber, instead of relying on post-sprayed flame retardants. The flame retardant property remains stable long-term without degradation under high-temperature aging or prolonged service, making them ideal for strict safety applications such as automobile cabins, industrial control equipment and new energy devices.
The standard V-0 grade can continuously withstand operating temperatures ranging from -40℃ to +120℃, perfectly fitting high-temperature enclosed and heat-prone environments such as engine bays, vehicle wiring harnesses and outdoor control boxes. To meet strict requirements from high-end clients, new energy projects and automobile OEMs, we can customize the GWIT 750℃ glow-wire flame retardant version. It passes the non-ignition glow wire test and matches the flame resistance standards of top imported brands including TE and Yazaki. It meets safety certification standards for vehicle controllers and industrial machinery, and can be directly applied in high-risk heat-generating equipment.
We adopt brand-new modified flame-retardant glass fiber raw materials without any recycled materials mixed in. The raw material itself has built-in properties of flame resistance, anti-aging and anti-cracking. After undergoing temperature cycling aging and damp-heat aging tests, the housing maintains intact structural strength and flame retardancy. No yellowing, brittleness or deformation occurs during long-term high-temperature operation. We fundamentally guarantee long-term fire safety of equipment through high-quality raw materials. Unlike low-end connectors made from recycled plastics, our products avoid potential safety risks caused by failed flame retardancy after short service time.
Smooth plugging performance mainly relies on three key factors: terminal material, structural design and mold precision, which constitute our core competitive advantages. Firstly, terminals are made of high-elasticity C5191 phosphor bronze. The spring reeds feature great toughness and stable resilience, avoiding the fatigue and deformation issues common to ordinary brass terminals. Secondly, optimized guiding bevels and foolproof positioning structures on both male and female ends automatically correct alignment during mating to prevent offset jamming and unilateral sticking. Thirdly, the built-in CPA secondary locking structure provides precise positioning and eliminates loose connections and clearances. This complete design fundamentally solves the common industry problems: tight fit for new plugs, loosening after prolonged use, and sticking during repeated insertion and removal.
All products feature highly standardized and consistent technical parameters that can be directly included in datasheets and acceptance criteria. The insertion force for a single terminal ranges from 15N to 35N, and the withdrawal force is between 8N and 25N. For multi-pin connectors, the mating force increases progressively with pin quantity to ensure even and controllable tightness. Manufactured with high-precision molds and automatic stamping processes, bulk goods maintain consistent tightness without deviation. There will be no inconsistent fit (too tight or too loose) within the same batch, making them perfectly suited for automatic wire harness production and mass equipment assembly.
The mechanical mating life reaches no less than 1,000 cycles with consistent plugging feel throughout the whole period, free from looseness or jamming. The terminal spring reeds are pre-shaped to deliver excellent fatigue resistance and vibration resistance. Under bumpy vehicle driving, frequent disassembly of industrial equipment and long-term vibrating working conditions, the reeds will not lose elasticity, suffer poor contact or incomplete insertion. The connectors remain tightly mated after long-term service, ensuring stable electrical connection and preventing power cut-offs and signal outages caused by component aging from repeated plugging and unplugging.

The core reason is the virtual connection of the door connector terminals and the failure of the locking structure, which leads to unstable contact resistance and insufficient power supply. In low temperature environment, the plastic shell shrinks and aggravates the contact gap, resulting in jamming and failure to lock. Choosing a body connector with CPA dual locking structure and low impedance terminals can prevent such problems from the source.
This is caused by unstable power supply due to vibration pin withdrawal and virtual connection of the door connector terminals. The high current load of the window raising instantly pulls down the loop voltage, and the horn power supply is interrupted. Connectors with dual locking structure and high current-carrying terminals can stabilize power supply and avoid such intermittent sound loss problems.
The main reason is the power supply fluctuation caused by poor contact of the connector terminals, and the control logic disorder caused by signal crosstalk. Body connectors with IP67 sealing, low impedance and signal isolation can stabilize power supply and signal transmission, and avoid the strobing and always-on problems of ambient lights.
The core problem is the insufficient clamping force of the connector terminals and the virtual connection caused by vibration, which leads to unstable power supply of the adjusting motor and delayed signal transmission. Connectors with CPA secondary locking and high clamping force terminals can ensure stable power supply and signal transmission, and restore the normal adjustment function of the rearview mirror.
The root cause is the virtual connection caused by the pin withdrawal of the door connector terminals and the bending of the wiring harness. When the door rotates to a specific angle, the terminals completely break away from the contact, and the electrical appliances are directly powered off. Connectors with dual locking structure and high clamping force terminals can prevent terminal pin withdrawal and avoid such angle failure problems.
The core reason is the insufficient current-carrying capacity of the headlight connector terminals and the virtual contact, which leads to large power supply voltage drop and the light power cannot be output at full load. Choosing headlight connectors with large cross-section phosphor bronze terminals and low impedance can reduce power supply loss and ensure full load stable output of lights.
The rear of the car has been facing the splashing of mud and water for a long time. After the sealing of the ordinary connector fails, water vapor penetrates, and the terminals are oxidized and corroded, resulting in a short circuit, which directly burns the fuse. The tail light connector with IP67 full sealing and anti-corrosion terminals can isolate the intrusion of mud and water, and avoid the problems of oxidation short circuit and fuse burning.
This is the abnormal loop resistance caused by poor contact of the connector terminals, and the flasher triggers abnormal stroboscopic after detecting the abnormal load. Headlight connectors with high clamping force and low impedance terminals can stabilize the loop resistance and restore the normal flashing frequency and brightness of the turn signal.
The reason is the defect of the sealing structure of the ordinary headlight connector, rainwater and car washing water vapor penetrate into the cavity, and the terminals are oxidized and rusted. The headlight connector with IP67 multi-layer silicone full sealing structure can completely isolate the intrusion of water vapor, and cooperate with thickened tin-plated anti-corrosion terminals to prevent oxidation and rust.
This is because the high and low current pins of the headlight connector are arranged without isolation, and the high current pins generate electromagnetic crosstalk, which leads to signal disorder and BCM false fault code. The headlight connector with cavity partition isolation design can block line crosstalk and eliminate the false alarm of fault code.
The core reason is the insufficient current-carrying capacity of the terminals and the virtual contact, which continuously accumulates heat when working at high current, and the temperature continues to rise, leading to the melting of the plastic shell. Choosing headlight connectors with high current-carrying terminals and high temperature resistant flame-retardant shell can reduce the working temperature rise and eliminate the hidden dangers of high temperature ablation and fire.
The reason is the insufficient current-carrying capacity of the tail light connector terminals and the virtual contact, which produces serious power supply voltage drop under the high current load of braking, and the light power cannot be output normally. Choosing tail light connectors with large cross-section and low impedance terminals can reduce power supply loss and ensure the brake light is lit at full power.
This is because the tail light connector buckle is loose and the terminal pin withdraws, the terminal instantly breaks away from the contact under bump vibration, and the brake light is temporarily powered off. The tail light connector equipped with CPA dual locking and high strength integrated buckle can lock the terminals firmly and prevent the instantaneous power failure caused by vibration.
