Description

about

 

Manufactured by Tongda Electronics, the MMCX-C-J1.5 RF connector belongs to the MMCX series of microminiature coaxial connectors and features a snap-on quick-connect mechanism. Compact, lightweight, and offering a secure, reliable connection, it is ideally suited for various RF devices with limited internal installation space.

 

structure

 

1. This MMCX-C-J1.5 RF connector features a three-piece coaxial design with a straight-exit cable configuration; its overall profile is compact, requiring minimal installation space.
2. The mating interface utilizes a gold-plated, slotted spring-contact structure, enabling quick, tool-free connection and locking for easy assembly; it ensures 360-degree circumferential contact and reliable shielding continuity.
3. Internally, the components are arranged coaxially-comprising a contact pin, PTFE dielectric, and metal housing-ensuring consistent impedance and low signal attenuation during high-frequency transmission.
4. The termination point employs a dual-crimp structure specifically designed for 1.5mm OD micro-coaxial RF cables; it independently secures the inner conductor and the outer shielding braid, ensuring the cable remains firmly attached and resistant to pull-out.
5. All contact components are gold-plated and manufactured with precise concentricity control; they are resistant to wear from repeated mating cycles and offer excellent oxidation and corrosion resistance for long-term use.

Applications

 

 

1. This MMCX-C-J1.5 RF connector features a compact design-smaller in overall dimensions than the standard MCX series-making it ideal for installation in various high-density integrated electronic devices.
2. It utilizes a reliable snap-on connection mechanism to ensure a secure mechanical bond, thereby maintaining stable electrical continuity and structural integrity over the long term.
3. The connector offers excellent broadband transmission performance with an operating frequency of up to 6 GHz, meeting the requirements of most high-frequency signal transmission applications.
4. Designed with a crimp-style termination, it simplifies the assembly process and is highly suitable for large-scale factory production lines.
5. Manufactured using high-quality materials and precision engineering, it ensures low signal transmission loss and superior transmission efficiency.

 

Installation and Adaptation

 

Our MMCX-C-J1.5 RF connector is designed for flexible, small-diameter RF cables with an insulation outer diameter of 1.5 mm; common compatible cable types include RG174/U, RG316/U, and SFF-50-1.5-1.
When assembling the connector, specialized RF crimping tools must be used to ensure a secure crimp that meets electrical connection standards. Additionally, avoid forcibly bending the cable during routing and ensure that the cable's braided shield makes full contact with the connector housing.
