4, ZION'S IQC (Incoming quality control) of raw material for Modular Plug/RJ Connector

Our quality inspectors will strictly inspect each batch of incoming raw material according to industry high standards and your order requirement.

The raw materials we use to make modular plugs are PC plastic. Select the durability, insulation performance, and easy shape shape of this material.


In addition to plastic shells, modular plugs also need metal contact to establish electrical connections. The contact is made of phosphorus bronze (copper content ≥65%), and phosphorus and bronze are a copper alloy, known for their excellent conductivity and mechanical strength. In order to increase the diversion and the stability of transmission, our company uses a trigeminal structure chip to close the contact with the core of the wires. At the same time, nickel plating copper and bronze are thick and gold -plated to ensure that it maintains high -quality conduction capabilities and Stability of long -term work.


For bending folding films, our shotcolic performance: Artificial 180 degrees bending crystal head handle, 1 back and forth, more than 20 times, continuous cracking.


Other components of modular plugs include strain materials, such as rubber or plastic, which can provide protection and stability for cable connection. These materials help prevent cables from being damaged and maintaining electrical connection.

6,IPQC(In-process quality control) of modular plugs

6.1, Physical performance test for modular plugs:

Visual Inspection: Operators or quality control personnel visually inspect the modular plugs at various stages of production to ensure they meet the required visual standards. This includes checking for any physical defects, such as cracks, deformities, or color inconsistencies.

Dimensional Measurements: Critical dimensions of the modular plug, such as overall length, width, height, and pin dimensions, are measured using specialized tools and gauges. These measurements are compared against specified tolerances to ensure compliance with the required standards.

Mechanical Strength Testing: Modular plugs may undergo mechanical strength testing to assess their durability and resistance to physical stress. This can involve performing pull tests or plug insertion/withdrawal cycles to verify that the plugs can withstand normal usage without breaking or deforming.

Strain Relief Evaluation: Strain relief components, such as rubber or plastic, are inspected to ensure they are properly installed and provide adequate protection to the cable connections. This can involve checking the secure attachment and flexibility of the strain relief material.

6.2, Electronic performance test for modular plugs:

Contact Resistance Test: This test measures the resistance between the plug contacts and the mating connector. It ensures low resistance values, indicating good electrical conductivity and reliable signal transmission.

Insulation Resistance Test: This test measures the resistance between the plug contacts and the plug body. It checks for adequate insulation properties to prevent short circuits and signal leakage.

Continuity Test: This test verifies the continuity of the wiring connections within the plug. It ensures that the correct pins are connected and that there are no open circuits or wiring errors.

Crosstalk Test: This test assesses the level of unwanted signal coupling between adjacent pairs of pins within the plug. It ensures that the plug design minimizes crosstalk, which can affect signal quality.

Return Loss Test: This test measures the amount of signal reflected back from the plug to the source. It evaluates the impedance matching and signal integrity of the plug, ensuring minimal signal reflections.

Insertion Loss Test: This test measures the signal loss that occurs when the plug is inserted into the mating connector. It evaluates the plug’s ability to maintain signal strength and minimize transmission losses.
