Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical fiber connectors, in particular to an MPO connector with a durable male head. Background Art
[0002] An MPO connector is a type of fiber optic connector that consists of a fiber ferrule, jacket, coupling assembly, and ferrule. The ferrule is the core component, typically made of high-precision ceramic or metal. It contains multiple parallel fiber optic holes to accommodate the optical fibers. The jacket protects the fibers and other components within, while the ferrule enhances the connector's mechanical strength and stability.
[0003] Currently, domestic base designs have a smooth end, without consideration for securing the spring position. This can cause the spring to bend at the front end after installation into the MPO housing due to factors such as the angle of installation and the applied force. This bending creates a non-horizontal, angled spring force, which can easily cause the spring's installation position to become unstable, impacting the overall quality of the connector. This force slightly offsets the base pin and ferrule, making it more difficult to remove the base pin from the mating ferrule PIN hole during repeated insertion and removal of the MPO connector. Increased insertion and removal can easily cause the ferrule to break, rendering the connector unusable. Furthermore, spring bending can damage the optical fiber, affecting the connector's performance. Utility Model Content
[0004] The purpose of the utility model is to address the defects and shortcomings of the existing technology and provide an MPO connector with a durable male head. The MPO connector has a base that can prevent the working position of the spring from shifting, and can avoid the front end bending of the spring that may be caused by the installation angle, force, etc. after being installed in the sheath, thereby ensuring that the spring installation position is stable and does not shift, protecting the PIN pins inside the connector, avoiding damage to the optical fiber caused by spring bending, and extending the service life of the connector. The utility model has high practicality.
[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: it includes a connector sheath 1, a base 2, a core 3, a spring 4, a limit seat 5, a connector tail pipe 6, and a spring hook 7; the core 3 is installed at the front end of the connector sheath 1, the spring 4 is located at the middle end of the connector sheath 1, and an integrally formed base 2 is arranged between the core 3 and the spring 4. Two spring hooks 7 are arranged on the right side of the base 2, the left end of the spring 4 is pressed against the right side of the spring hook 7, and the right end of the spring 4 is pressed against the limit seat 5; the right end of the connector sheath 1 is divided into a connector tail pipe 6.
[0006] Furthermore, the middle portion of the base 2 is a wire threading groove 201 .
[0007] Furthermore, a wire clamping groove 202 is provided on the upper portion of the wire threading groove 201 .

[0011] Furthermore, the two spring hooks 7 are arranged on the right side of the base 2 corresponding to the two sides of the threading groove 201.
[0012] The working principle of the utility model is as follows: two hooks are added to the original base design to fix the spring and reduce the impact of possible bending of the spring on the connector. The opening position of the hook on the base can be adjusted according to actual usage conditions. During the production process of the base parts, bases with different hook positions can be produced to suit the installation environment adapted to different spring parts.
[0013] After adopting the above technical solution, the beneficial effects of the utility model are as follows: it has a base that can prevent the working position of the spring from shifting, and can avoid the front end bending of the spring due to the insertion angle, force, etc. after being installed in the sheath, ensuring that the installation position of the spring is stable and not shifted, protecting the PIN needle inside the connector, avoiding damage to the optical fiber caused by spring bending, and increasing the service life of the connector, which has high practicality.
