Product Information
The ACC-SMD-3P-5-C is a dedicated 90-degree planar L-shaped solderless connector engineered specifically for 3-wire, 5mm wide bare-board SMD LED strip lights. Standard corners often force tight bends that break copper traces, but this solderless led connector creates a flat, clean 90-degree turn in confined channels. Simply insert both cut ends of your bare-board LED strip into the connector slots, align the 3 copper solder pads directly over the metal contact prongs, and press firmly with standard pliers to pierce through the solder points. Designed for precision installations using super small 5mm LED tape and select ultra-narrow addressable LED strips, this connector removes the requirement for field soldering.
Key Features
5mm PCB Compatibility
Engineered exclusively for ultra-slim 5mm wide 3-wire bare-board LED strip circuits.
Solder-Free Piercing Mechanism
Dual-sided metal teeth pierce copper pads using standard slip-joint pliers without a soldering iron.
Secure 3-Conductor Alignment
Maintains dedicated spacing for DC+, Data/CCT, and GND lines to prevent short circuits.

Application Scenarios
How to Install & Use This Corner Connector
- Cut your 5mm 3-wire LED strip squarely along the designated cut line with sharp scissors.
- Inspect the cut edge to ensure copper contact pads on both segments are clean and free of adhesive backing overlap.
- Insert the first LED strip segment into the connector slot until the copper pads sit directly under the metal piercing pins.
- Verify polarity markings (+, Data/WW, -) align identically on both sides of the corner connector.
- Slide the second LED strip segment fully into the opposite slot, aligning its contact pads beneath the pins.
- Use flat-nose pliers to press the clear plastic clamp cap downward firmly and evenly until it sits completely flush.
- Power on your 5V, 12V, or 24V power supply to test electrical continuity across all 3 channels before permanent mounting.
⚠ Precautions
- Compatibility constraint: This unit works ONLY with 3-wire, 5mm wide bare-board (IP20) SMD LED strip lights.
- Do not use with 8mm, 10mm, or 12mm LED strip lights; wider boards will not enter the guide track.
- Do not use on IP65, IP67, or IP68 waterproof LED strip lights; silicone coatings and tubes prevent piercing pins from contacting the copper.
- Press down evenly across the entire surface with pliers; uneven pressure can bend internal pins and cause intermittent connection.
- Confirm conductor order (+, Data, GND or +, CW, WW) matches on both strip ends before crimping; reversing polarity will prevent operation.
- Do not exceed the 3A maximum current threshold across any individual conductor pin.

Frequently Asked Questions
Q: are led strip light connectors universal
A:No, LED strip light connectors are not universal. They are manufactured for specific PCB widths (such as 5mm, 8mm, 10mm, or 12mm), specific pin counts (2, 3, 4, 5, or 6 pins), and specific IP ratings. This ACC-SMD-3P-5-C connector works only with 3-pin, 5mm wide bare-board SMD LED strip lights.
Q: how to connect led light strips with connectors
A:Cut the LED strip along the cut mark, slide the bare end into the connector port so the copper solder pads rest directly under the internal piercing prongs, align matching polarity markings, and squeeze the cap shut with pliers until flush.
Q: how to connect led strip light connectors
A:Insert both cut segments of your 5mm bare-board LED strip into each port of this L-shaped connector, align pin polarity across both segments, and compress the piercing cap downward using flat-nose pliers for a firm solder-free connection.
Q: how to fix led light strip connector
A:If an LED strip connector fails to conduct, inspect pad alignment to confirm the metal teeth pierced directly through the copper pads. Re-press firmly with pliers to ensure full terminal penetration, or cut a fresh strip section and reseat the connector.
Q: Can I use this connector on waterproof silicone-coated LED strip lights?
A:No. This connector is designed solely for IP20 bare-board LED strip lights. Silicone coatings, epoxy coatings, or waterproof sleeves prevent the piercing contacts from seating firmly onto the copper solder pads.
Q: What is the maximum voltage and current this connector can handle?
A:The ACC-SMD-3P-5-C supports operating voltages from 5V to 24V DC and carries up to 3A of continuous current per pin.
Q: Is soldering completely eliminated with this corner connector?
A:Yes. The insulation-piercing internal prongs penetrate through the copper pads on the LED strip PCB when pressed with standard pliers, delivering full electrical continuity without solder.
