Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of optical cable laying, and specifically relates to an optical cable protection structure. Background Art
[0002] When installing temporarily laid optical cable lines, the existing technology usually uses cable troughs to protect the cables. However, in order to facilitate plugging and unplugging and meet the requirements of connector heat dissipation performance, the connection ends of the optical cable lines are usually no longer covered by the cable troughs. Therefore, when the connection ends of the optical cable are partially stepped on, the locking buckles of the ends will be deformed, and a pulling force will be generated on the tail end of the cable, which will make it easier for the ends to fall off. Therefore, there is a need for a protective structure that is convenient for temporary plugging and unplugging of the connection ends of optical cable lines laid on the ground and does not affect the heat dissipation performance of the connector.

[0017] A connecting end support piece 43 is fixedly connected to the bottom of the anti-pressure-detachment support piece 41, and one end of the anti-pressure-detachment point positioning clamp 42 passes through the anti-pressure-detachment support piece 41 and is slidably connected to the anti-pressure-detachment support piece 41; the connecting end support piece 43 is used to increase the pressure-bearing capacity of the anti-pressure-detachment support piece 41 to avoid direct pressure on the buckle of the optical cable connection end when stepping on the end head protective shell 2.
[0018] The first support end piece 31 is provided with a positioning card hole 311, and the bottom end of the anti-pressure-detachment positioning card 42 is slidably connected to the positioning card hole 311; in the present embodiment, the positioning card hole 311 serves to increase the connection surface when the first support end piece 31 and the arc-shaped sliding card head 423 are engaged, thereby preventing the first support end piece 31 and the anti-pressure-detachment support piece 41 from being disengaged when only subjected to a small pulling force when stepped on, thereby effectively improving the support effect.
[0019] The anti-pressure-off point positioning clamp 42 is composed of an inner retractable seat 421, a connecting spring 422 and an arc-shaped sliding clamp 423.

[0020] In this embodiment, when the drawer cover 11 slides toward the inner side of the end head protective housing 2, the arc-shaped sliding clamp head 423 is squeezed by the wall surface of the first supporting end piece 31 and retracts toward the inner side of the retractable seat 421 until the arc-shaped sliding clamp head 423 is aligned with the positioning clamp hole 311 provided in the first supporting end piece 31, and then the arc-shaped sliding clamp head 423 is engaged with the inner side of the positioning clamp hole 311 through the rebound of the connecting spring 422, so that the first supporting end piece 31 and the anti-pressure drop point positioning clamp 42 are kept in a positioning state, and the anti-pressure drop point positioning clamp 42 is provided through the first supporting end piece 31 and the composite supporting end piece 32.

At this time, the upper and lower layers of the anti-pressure-off support sheet 41 are respectively received by the first supporting end sheet 31 and the composite supporting end sheet 32. The composite support end piece 32 provides support to form a locking interception surface for the snap-in part of the optical cable connection end. When the end head protective shell 2 is partially subjected to stepping pressure, the optical cable connection end is supported by a multi-level structure formed by the first support end piece 31, the composite support end piece 32, the anti-pressure support piece 41 and the connection end support piece 43, to prevent the optical cable connection end snap-in from being directly subjected to force and detached from the connection end.
