The **AP105-DF1B-R** is a specialized precision mechanical component used in the electronics manufacturing industry, specifically for wire termination. It is a ** Hirose Electric Applicator** designed for use with automatic or semi-automatic crimping presses. --- ### 1. Technical Specifications The AP105-DF1B-R is engineered to crimp specific Hirose terminals onto wires with high repeatability. | Attribute | Details | | :--- | :--- | | **Manufacturer** | Hirose Electric Co Ltd | | **Series** | DF1B | | **Tool Type** | Applicator (Side Feed) | | **Compatibility** | Hirose DF1B Series Contacts | | **Applicable Wire** | 20-30 AWG (depending on specific terminal) | | **Press Type** | Hirose CM-105C or compatible standard presses | --- ### 2. Key Electronic & Mechanical Components While the applicator is a mechanical tool, its "electronic" relevance lies in its integration with motorized presses and the precision required for electrical connectivity. #### A. The Crimping Die (Anvil and Punch) These are the core components that deform the metal terminal around the wire. * **Insulation Barrel Punch:** Crimps the outer terminal wing around the wire insulation for strain relief. * **Wire Barrel Punch:** Compresses the wire strands into the terminal to create a gas-tight electrical connection. #### B. Feeding Mechanism * **Feed Finger:** Uses a mechanical linkage to advance the "tape" or "reel" of terminals after every crimp cycle. * **Adjustment Dial:** Allows for micro-adjustments to the crimp height (C.H.), which is critical for ensuring low contact resistance in the final electronic assembly. #### C. Interface with the Press The applicator features a **ram** that connects to the electric motor of the crimp press (like the CM-105). This allows for: * **Stroke Control:** Ensuring the terminal is crushed to the exact millimeter specified by Hirose. * **Cycle Counting:** Often integrated with electronic sensors to track production volume. --- ### 3. Purpose in Electronics Manufacturing The AP105-DF1B-R is essential for the high-speed production of **Wire-to-Board (WTB)** connectors. 1. **Ensuring Conductivity:** By applying specific pressure, it breaks through surface oxidation on the wire to ensure a high-quality electrical path. 2. **Standardization:** It eliminates the variability of manual hand-crimping, ensuring every connector meets UL/CSA standards. 3. **Efficiency:** Designed for "Reeled" terminals, allowing for thousands of terminations per hour. ---
