Using same shell, while being provided with the fiber chamber outconnector technical solution that buffer structure prevents lock pin from causing damage.
To achieve the goals above, a kind of outdoor connector with buffer structure and twin-core multicore common enclosure is designed,
Including twin-core kernel 12 or multicore kernel 19, shell 18 and stop member,
The twin-core kernel 12 includes twin-core kernel stop member 2, lock pin 3, spring 4 and push piece 5, and the twin-core kernel stop member 2 is in length
Cube, in advance in 2 cavity of twin-core kernel stop member, prepackage constitutes twin-core kernel 12 for lock pin 3, spring 4 and push piece 5；
The multicore kernel 19 includes multicore kernel stop member 7, push piece 5, spring 4 and MT lock pin 6, and the multicore kernel 19 is in rectangular
Body, push piece 5 constitute multicore kernel 19 by spring 4 and the prepackage of MT lock pin 6；
It is characterized by:
8 shape of stop member ontology is matched with 18 inner cavity of shell, and 8 two sides of stop member ontology are equipped with the resilient clamp member extended downwardly
10,10 bottom end of resilient clamp member is equipped with buckle and cooperates with the stuck point on shell, and 8 lower part two sides of stop member ontology are equipped with hollow out knot
Structure 9, the resilient clamp member 10 of stop member is used to block the forward and backward face of twin-core kernel 12 or multicore kernel 19, and cooperates in shell 18
Connection, the engraved structure 9 of stop member is for accommodating twin-core kernel 12 or the left and right face of multicore kernel 19.
A kind of outdoor connector with buffer structure and twin-core multicore common enclosure, it is characterised in that in twin-core
The forward and backward face of core 12 is equipped with convex block, and the front and back ends of stop member engraved structure 9 are all provided with the fluted convex block with twin-core kernel 12 and cooperate.
A kind of outdoor connector with buffer structure and twin-core multicore common enclosure, it is characterised in that shell 18
Inner cavity lower part is equipped with step structure 11, and for accommodating buffer spring 13,13 one end of buffer spring connects twin-core kernel 12 or multicore
19 bottom of kernel, the step structure 11 of 18 inner cavity of other end connected with outer casing.
Compared with the existing technology, composite structure simple possible is easily installed and dismantles the present invention, the advantage is that:
1. can reduce the material of fiber chamber outconnector using the design of twin-core and multi-core connector common enclosure and be produced into
This.
2. connector uses compact structure, connector outer diameter is 14mm, can save the space of application scenarios.
3. the design of buffer spring can cause optical fiber at the time of contact to avoid multicore lock pin and be inserted since instantaneous pressure is excessive
The damage of core end face.
