Copper Wire Connector Manufacturer Overview
What is the 314 low voltage splice connector?
The 314 connector is a self-stripping IDC pigtail connector used for low voltage wire splicing. Compatible unstripped solid copper wires are inserted into the connector body, and the cap is pressed down to drive the U-contact through the insulation and into the conductors. The three-dimensional body has a blue cap and translucent-white housing, and the connector is selected for low voltage electrical wiring, legacy telecom repair, alarm and sensor wiring, lighting, and thermostat wiring when wire size and installation conditions match.
- 314-type low voltage IDC splice connector
- Self-stripping connection for supported solid copper wires
- For 2 or 3 wire pigtail splicing
- Silicone grease filled for moisture resistance
- No stripping, twisting, soldering, or heat shrink required
- Bulk supply for B2B and distributor orders

Connection Method
How the self-stripping IDC U-contact works
The 314 connector uses a bronze tin-plated U-contact inside the connector. When the cap is pressed down, the U-contact displaces the insulation and grips the solid copper conductors. This allows the connector to complete the splice without pre-stripping the wire. The connector is silicone grease filled for moisture resistance. The sealing grease helps protect the connection area in suitable low voltage installations. Mintel describes the 314 connector separately from gel-filled jelly crimp connectors such as UY, UY2, UR, and UR2.
- U-contact cuts through insulation during pressing
- Designed for supported solid copper wires
- Silicone grease supports moisture resistance
- No wire stripping or twisting is required
- Separate from gel-filled UY/UR-style jelly crimp connectors
Installation
314 connector installation steps
314 connectors are installed by inserting compatible unstripped wires into the connector and pressing the cap until the connection is fully seated. Installation should be performed according to the buyer's application requirements and applicable electrical practice.
- Turn off power before installation.
- Confirm the wires are solid copper and within 0.6-1.25 mm diameter / 22-16 AWG.
- Confirm the insulation outside diameter does not exceed 3.08 mm / 0.12".
- Insert 2 or 3 unstripped wire ends fully into the connector body.
- Press the cap evenly until it is fully seated.
- Check that the wires are held securely and the connector is properly closed.
Applications
Where 314 low voltage splice connectors are used
The 314 connector is used in selected low voltage wire splicing applications when the wire size, voltage, environment, moisture exposure, and installation conditions match. It is especially useful when installers need a quick IDC splice without stripping or twisting the wire.
- Low voltage electrical wiring

Comparison
314 connector vs jelly crimp connectors
314 connectors and jelly crimp connectors are both IDC splice products, but they are used for different wiring contexts. The 314 connector is a low voltage pigtail splice connector with a three-dimensional body and silicone grease sealing. Jelly crimp connectors such as UY, UY2, UR, and UR2 are compact telecom splice connectors with gel filling and flat button-style caps.
| Factor | 314 low voltage splice connector | Jelly crimp connectors |
|---|---|---|
| Typical models | 314 | UY, UY2, UR, UR2, UB2A |
| Body style | Three-dimensional pigtail connector | Flat button-style telecom connector |
| Wire type | Solid copper only | Solid copper telecom wire |
| Wire count | 2 or 3 wires | Depends on model |
| Sealing | Silicone grease filled | Gel-filled |
| Main use | Low voltage pigtail splicing | Copper telecom repair and splicing |
| Packaging | Loose / bulk only | Depends on model and order |
