[0024] According to the embodiment of the utility model, a kind of MPO loose parts portable limit seat is provided.

[0025] The utility model is further illustrated by combining with the specific embodiment and the drawing, as shown in Figures 1-5 According to the embodiment of the utility model, a kind of MPO loose parts portable limit seat, it includes limit seat 1 and MPO loose parts 2, the limit seat 1 is connected in the side end of MPO loose parts 2, the tail of limit seat 1 is provided with seat body 3, seat body 3 is provided with through hole 4, the inner side of through hole 4 is equipped with arc edge 41, the end away from seat body 3 is provided with clamping seat 5, the clamping seat 5 is equipped with two groups of clamping arms 51, two groups of clamping arms 51 are equipped with positioning protrusion 52 and limit block 53, the positioning protrusion 52 is connected in the end of clamping arm 51, limit block 53 is arranged at the junction of clamping seat 5 and seat body 3.

[0026] In one embodiment, the limit seat 1 is made of high-strength engineering plastic or aluminum alloy material. It has good mechanical strength and stability, and can withstand certain external impact without deformation.

[0027] In one embodiment, the MPO loose parts 2 are composed of a housing, a plug core, a male base, a spring, a limit seat 1, and a flat ribbon fiber tail sleeve.

[0028] In one embodiment, the surface of the seat body 3 is provided with a groove 31.

[0029] In one embodiment, the through hole 4 is circular or slot-shaped and communicates with the clamping seat 5. The shape of the through hole 4 matches the outer shape of the MPO loose parts 2. One end of the MPO loose parts 2 is aligned with the through hole 4 on the seat body 3, and then the MPO loose parts 2 are inserted into the clamping seat 5 along the inclined edge direction of the clamping arm 51.

[0030] In one embodiment, the clamping arm 51 is an elastic connecting component, and the connection between the clamping arm 51 and the seat body 3 is provided with an inclined edge 54, and the inner side of the clamping arm 51 is provided with an arc angle 511.

When the MPO loose piece 2 is inserted to a certain depth, the positioning protrusions 52 on the card arm 51 are accurately embedded into the clamping grooves or positioning holes of the MPO loose piece 2, and at the same time, the limiting blocks 53 prevent the MPO loose piece 2 from continuing to be inserted, ensuring the accuracy of the installation position. The card arm 51 tightly clamps the MPO loose piece 2 under the action of elasticity, so that the MPO loose piece 2 is tightly attached to the seat body 3, and the combined action of the friction force, the positioning protrusions 52 and the limiting blocks 53 realizes the stable fixing of the MPO loose piece 2.

[0033] When the MPO loose piece 2 needs to be disassembled, the operator only needs to slightly bend the card arm 51 outward, so that the positioning protrusions 52 are separated from the clamping grooves or positioning holes of the MPO loose piece 2, and then the MPO loose piece 2 is pulled out along the direction of the inclined edge of the card arm 51, which is simple and convenient to operate, without the need for complex tools, and greatly improves the efficiency of installation and disassembly.
