Spec Sheet - ACC-SMD-3P-5-BTB

Availability	In Stock
Condition	Brand New

The ACC-SMD-3P-5-BTB is a specialized board-to-board led strip light connector engineered specifically for ultra-narrow 3-pin 5mm SMD LED strip lighting. When working on tight architectural reveals, custom cabinet joinery, or bespoke linear fixtures, soldering 3 copper pads spaced across a miniature 5mm width is time-consuming and risks thermal damage to neighboring diodes. This compact led strip connector solves field-assembly challenges by delivering a secure, mechanical clamp connection without an iron or solder. Measuring only 10mm in length, 6mm in width, and 5mm in height, its low-profile housing fits inside narrow aluminum extrusions and tight raceways. Designed for seamless end-to-end runs, it aligns internal piercing pins directly over the strip copper solder pads for reliable electrical continuity.

Key Features

Engineered for 5mm 3-Pin Form Factors

Precisely sized to seat ultra-narrow 5mm wide flexible printed circuit boards carrying 3 conductors.

100% Solderless Mechanical Clamp

Eliminates hot soldering irons in the field by utilizing internal contact pins pressed with standard pliers.

Ultra-Compact 10x6x5mm Enclosure

Maintains a minimal 6mm exterior profile to slide effortlessly inside slim aluminum channels.

Zero-Wire Board-to-Board Extension

Connects two cut sections of LED strip end-to-end without unsightly wire loops or pitch interruption.

Durable High-Temperature Housing

Constructed from flame-retardant polycarbonate that retains spring tension and contact pressure over continuous operation.

Technical Highlights

Specifically keyed to bridge cut ends of super small 5mm LED strip runs without widening the profile footprint.
Internal metal contacts align directly with copper solder pads on 3-conductor tape, supporting dual-white and addressable configurations.
Works seamlessly when joining continuous segments of 3-wire tunable white LED strip lights for dynamic CCT architectural transitions.
Compatible with compact data-line setups such as ultra-narrow addressable LED strips requiring positive, ground, and data continuity.
Transparent clear-top casing allows visual inspection of copper pad alignment before closing the clamp down with pliers.

Application Scenarios

Custom Cabinet & Display Case Joinery Extend ultra-slim 5mm LED strip lights across multiple millwork shelves without bulky jumper wires. The 6mm outer width fits inside recessed routed grooves for seamless museum and retail display illumination.

CCT Tunable White Linear Accent Runs Bridge cut lengths of 3-conductor tunable white LED strip lights around long perimeters. The internal copper contacts maintain solid positive, warm white, and cool white channel continuity without soldering.

Addressable 3-Wire Compact Data Runs Rejoin cut sections of narrow 5mm digital LED strip lights where DC+, GND, and Data lines must continue across extended runs in signage, cove lighting, or architectural linear accents.

How to Use This Solderless Connector

Step 1: Cut the 5mm 3-pin LED strip precisely along its designated cut line using sharp shears to preserve full copper contact pads on both sides.
Step 3: Insert the first cut LED strip into one end of the connector until the copper solder pads sit squarely under the internal contact pins.
Step 4: Verify polarity matching (+, CW, WW or +5V, Data, GND), then insert the second LED strip into the opposite end until both strips meet in the center.
Step 5: Inspect visually through the casing to confirm all 3 pins align directly over the copper pads on both strips.
Step 6: Place standard pliers flat across the connector housing and squeeze firmly and evenly until the clamp snaps completely flush into the locked position.
Step 7: Power on the DC power supply to test electrical continuity before mounting the assembled LED strip into an extrusion or onto the final surface.

⚠ Precautions

Compatibility check: This connector works ONLY with 5mm wide, 3-pin LED strip formats. It does NOT fit 8mm, 10mm, or 12mm strips.
Observe conductor alignment: Always match the polarity markings printed on both LED strip segments (e.g., +, -, D or +, W1, W2). Inverting the strip will prevent proper operation.
Even pressure required: Use flat-jaw pliers to apply even pressure across the entire top surface. Uneven hand pressure can distort the pins or crack the polycarbonate housing.
IP rating limitation: This connector is rated IP20. It is intended for dry indoor environments only. Do not use in outdoor, damp, or wet locations without secondary waterproof sealing.
Current limit: Do not exceed 3.5A total current through the connector to prevent contact resistance heating over long continuous runs.

Frequently Asked Questions

Q: are led strip light connectors universal

A:No, LED strip light connectors are not universal. They must match the exact PCB width (such as 5mm, 8mm, 10mm, or 12mm) and the exact pin count (2-pin, 3-pin, 4-pin, 5-pin, or 6-pin) of your specific LED strip.

Q: how to connect led light strips with connectors

A:Cut the LED strip along the designated cut line, strip back 8mm of adhesive tape, slide both cut strip ends into each side of the connector ensuring copper pads align with the metal pins, and press the housing firmly shut using pliers.

Q: how to connect led strip light connectors

A:To connect this board-to-board unit, insert one strip into each opposing port so the copper solder pads face the internal contact teeth, verify that the polarity markings match on both ends, and squeeze the connector closed with pliers until locked.

Q: how to fix led light strip connector

A:If a section flickers or fails to light, disconnect power, inspect the connector to ensure both strips were inserted completely, check that the contact pins pierced the copper pads accurately, and re-clamp firmly with pliers to ensure solid pin contact.

Q: Will this connector fit an 8mm or 10mm LED strip?

A:No. The internal channel is molded precisely for 5mm wide flexible printed circuit boards. 8mm or 10mm strips will not fit into the slot.

Q: Is soldering required when using this connector?

A:No, this is a completely solderless connector. It uses mechanical piercing pins that make direct contact with the strip copper pads when pressed closed with pliers.

Q: Can I use this connector outdoors or in wet areas?

A:No. The ACC-SMD-3P-5-BTB has an IP20 rating designed for dry indoor applications. It must be housed in a sealed, waterproof enclosure or heat shrink if used in moisture-prone environments.

Q: What is the maximum current load this connector can handle?

A:This connector supports up to 3.5A total current across its conductors, with a maximum rating of 1.5A per individual pin under DC 5V to 24V operation.
