Based on an integral injection molding structure with the net tails and low cost, the branching structure provided by the utility model integrates the compatibility of an injection mould to the wire diameter size, further adopts the net tail structures, and uses a dual-wall glued heat shrinkage bush to perform heat shrinkage sealing, so that the reliable sealing is realized.

Description

A kind of minute line structure

Technical field

The utility model relates to communication technical field, particularly a kind of minute line structure.

Background technology

At present, become the communication architecture of TD-SCDMA main flow based on the fiber optic stretch macro base station of BBU+RRU technology (Base Band Unit (Base Band Unit), Remote Radio Unit (Radio Remote Unit)).The outdoor extensive use of RRU, sealing for the outside wire cable joint has had stricter requirement, in same cable, control signal or power supply class signal connect the final inconsistent situation of whereabouts, need the design sealing to divide line structure, various types of signal in the cable is branched away,, divide line structure need realize positiver sealing for some outdoor application scenarioss.

The application mode of the outdoor separated time of existing this class mainly contains two classes:

First kind application mode, need be at the line footpath requirement of application-specific scene, special die sinking customization deconcentrator, line footpath demand has the words of change, application adaptability is relatively poor, field demand that can't the multiple not collinear footpath of flexible adaptation, if according to various application scenarioss all die sinking customize special deconcentrator, divide the meeting of line structure kind a lot, and cost is higher.

The second class application mode, adopted injection molding way, mould can be adjusted flexibly, and the external mold line outlet can use same secondary mould, adapts to multiple line footpath, but because wire rod and outer mold materials have certain difference, and sealing and reinforcing can't be carried out in external mold and wire rod junction, uses or out of doors under the scene of cyclic strain the easy outlet of wire rod and external mold junction slit for a long time, water easily pours into external mold inside from the slit, cause the application risk.

The utility model content

The utility model provides a kind of minute line structure, has solved the sealing problem of outdoor minute line structure with lower cost.

A kind of minute line structure comprises: injection moulding body 1, the two ends of described injection moulding body 1 are respectively equipped with inlet wire net tail 2 and go out gauze tail 3, described injection moulding body 1 and described inlet wire net tail 2 and describedly go out gauze tail 3 and be integral structure.

Described inlet wire net tail 2 and describedly go out between gauze tail 3 and the wire rod by the sealing device sealing, described wire rod is made of inlet wire wire rod 41 and outlet wire rod 42.

Described sealing device is specially point of incoming cables double-walled band glue heat-shrinkable T bush 51 and outlet double-walled band glue heat-shrinkable T bush 52.

Described inlet wire net tail 2 and describedly go out gauze tail 3 and be provided with inlet wire net stern notch 21 and go out gauze stern notch 31, described inlet wire net stern notch 21 and describedly go out gauze stern notch 31 and be used to reinforce point of incoming cables double-walled band glue heat-shrinkable T bush 51 and outlet double-walled band glue heat-shrinkable T bush 52.

Described injection moulding body 1 is provided with colligation groove 11, and described injection moulding body 1 is fixed in the colligation point via described colligation groove 11.

Described injection moulding body 1 profile is square, circular or other arbitrary shape structures.

Described go out gauze tail 3 be 2 or more than.

Described 2 or the above gauze tail 3 that goes out are arranged in a row or arrange more, and adjacent two rows described goes out 3 dislocation of gauze tail and arrange.

Shown in 2 or above go out the 3 concentric annular arrangements of gauze tail.

Shown in 2 or above go out gauze tail 3 positive triangular shapes and arrange.

A kind of minute line structure among the utility model embodiment solved the sealing problem of outdoor minute line structure with lower cost.The utility model is simple in structure, use the versatility injection mold structure to realize, so cost is lower; Adopt the mode of injection moulding processing, go out the gauze tail and can adapt to multiple line footpath; In addition, owing to be provided with net stern notch structure on the net tail, can use comparatively reliable double-walled band glue heat-shrinkable T bush to carry out outside seal, thereby strengthen sealing; Because the injection moulding body is provided with the colligation groove, thereby has avoided the outdoor problem that causes the reliability loose contact of rocking for a long time.In a word, the utility model mainly from a kind of cheaply with the structure of net tail integral type injection moulding, brought into play the compatible characteristics of injection molding body to line footpath size, utilize the net stern construction simultaneously again, use double-walled band glue heat-shrinkable T bush to carry out the pyrocondensation sealing, realized positiver sealing.
