The **E14-R** typically refers to a standard **E14 Lamp Holder (Small Edison Screw - SES)** designed for high-heat environments, often used in appliances like ovens, microwaves, or specialized lighting fixtures. Below is a breakdown of the electronic components and technical specifications associated with this part. --- ## 1. Core Components and Materials The E14-R is engineered to withstand extreme temperatures (often up to 300°C) and high electrical stress. | Component | Material | Function | | :--- | :--- | :--- | | **Housing/Body** | Ceramic (Steatite/Porcelain) | High-temperature insulation and structural integrity. | | **Center Contact** | Copper Alloy / Nickel-plated | Conducts current to the base of the bulb. | | **Screw Shell** | Brass / Stainless Steel | Holds the bulb securely and completes the neutral circuit. | | **Terminals** | Screw-type or Tab terminals | Connection points for incoming power wires (Phase/Neutral). | | **Seals/Gaskets** | Silicone or PTFE (Optional) | Provides IP rating or moisture resistance in humid environments. | --- ## 2. Technical Specifications Most E14-R components adhere to the following electrical standards: * **Voltage Rating:** 230V - 250V AC (Standard Mains). * **Current Rating:** Usually 2A. * **Temperature Rating (T):** Marked as T300 (300°C) for oven use or T210 for general appliances. * **Socket Type:** E14 (14mm diameter screw thread). --- ## 3. Electrical Connection Diagram The wiring for an E14-R socket is straightforward, typically involving two points of contact. ```text Power Source (230V AC) | +---- [ L ] ----> Center Contact (Hot/Live) | +---- [ N ] ----> Outer Screw Shell (Neutral) ``` > **Safety Note:** In high-heat applications, the wiring connected to the E14-R must be high-temperature resistant (e.g., glass fiber or silicone insulated wires). --- ## 4. Key Features for Electronic Design 1. **Thermal Stability:** Unlike plastic E14 sockets, the E14-R uses ceramic to prevent melting or carbonization under thermal load. 2. **Vibration Resistance:** The "-R" variant often implies a reinforced or "Rugged" design to ensure the bulb does not loosen due to appliance vibrations. 3. **Mounting Options:** Usually features a snap-in or screw-flange mounting system for easy integration into metal chassis. ---
