Abstract
The utility model relates to a kind of video line adapter coupling structure, comprise video line and heart yearn patchcord, the video heart yearn joint of video line and the adapter coupling of heart yearn patchcord are in the same way together with coincidence chain intermittent weld, the part away from heart yearn solder joint of heart yearn patchcord, distance heart yearn solder joint preseting length place's inflection 180 °, arranges outer heat-shrinkable T bush after inflection outside adapter coupling part.In structure of the present utility model, heart yearn solder joint two ends deformational stress point away from heart yearn solder joint, like this, when video line switching place bends, folding s tress is no longer applied to solder joint place, substantially reduces the stressed of switching place solder joint, avoid broken string situation to occur, improve reliability.
Description
Technical field
The utility model relates to the wiring construction that a kind of video line is connected with patchcord.
Background technology
In the production process of modern times many optoelectronic devices, vision signal is undertaken deriving by aviation connector and is conducted, but existing many spininess aviation pressure contact connectors do not have special to crimp pin (or hole) contact with video line interface, and this just needs to transfer between video line and the contact of connector.In addition, also need in the use procedure of conducting slip ring the self brought line of conducting slip ring to be transferred into dedicated video line, to improve the antijamming capability of product transmission of video.
At present, the direct-connected mode of patchcord is normally welded direct on video line by the making of video line adapter coupling, specifically as shown in Figure 1, the heart yearn joint 11 of video line 1 and shielded joint 12 overlap to be in juxtaposition in mode in opposite directions with the joint of heart yearn patchcord 21 and the joint that shield patchcord 22 respectively and then weld, and overlap and load onto interior heat-shrinkable T bush 4 and outer heat-shrinkable T bush 5 after welding; In this adapter coupling, because video heart yearn and shielding conductor and patchcord all there are differences in line style, wire diameter, and welding position is very hard after welding, swing back and forth at cable, vibrate or bending time, stress suffered by welding point place two ends cable is different, easily cause joint to break, thus cause the problems such as product reclamation work amount is large, connector rapid wear, add the maintenance cost of product.
Utility model content
The purpose of this utility model is to provide a kind of video line adapter coupling structure, to solve the technical problem that prior art center tap weld easily ruptures.
For achieving the above object, the utility model adopts following technical scheme: video line adapter coupling structure, comprise video line and heart yearn patchcord, the video heart yearn joint of video line and the adapter coupling of heart yearn patchcord are in the same way together with coincidence chain intermittent weld, the part away from heart yearn solder joint of heart yearn patchcord, distance heart yearn solder joint preseting length place's inflection 180 °, arranges outer heat-shrinkable T bush after inflection outside adapter coupling part.
Interior heat-shrinkable T bush is provided with outside described heart yearn solder joint.
The part of the outer heat-shrinkable T bush of correspondence of the shielding conductor of described video line is in outer heat-shrinkable T bush.
Because the adapter coupling of video heart yearn joint of the present utility model and heart yearn patchcord adopts juxtaposition in the same way to weld together, then by the hindfoot portion of heart yearn patchcord from heart yearn solder joint preseting length place to inflection 180 °, by arranging outer heat-shrinkable T bush outside adapter coupling part, heart yearn patchcord and video line are tightened at adapter place, make heart yearn solder joint two ends deformational stress point away from heart yearn solder joint, like this, when video line switching place bends, folding s tress is no longer applied to solder joint place, substantially reduce the stressed of switching place solder joint, avoid broken string situation to occur, improve reliability.
Further, outside the solder joint of video heart yearn joint and heart yearn patchcord joint, arrange interior heat-shrinkable T bush, interior heat-shrinkable T bush is the separately protected structure of butt welding point, and inside and outside heat-shrinkable T bush forms the duplicate protection to adapter coupling, and reliability improves further.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing video line adapter coupling;
Fig. 2 is the structural representation of a kind of embodiment of the utility model.
Embodiment
The utility model video line adapter coupling structure as shown in Figure 2, it comprises video line 1, heart yearn patchcord 21 and shielding patchcord 22, video line 1 adopts video masking line, the video heart yearn joint 11 of video line 1 and the adapter coupling of heart yearn patchcord 21 overlap together with chain intermittent weld in mode in the same way, after welding, the part away from heart yearn solder joint of heart yearn patchcord 21 rolls over 180 ° at distance heart yearn solder joint preseting length place (as distance heart yearn solder joint 10mm-15mm place) to back bending, in similar U-shaped bending, carry out pyrocondensation at the outer heat-shrinkable T bush 15 of the overcoat of adapter coupling part after inflection to tighten, the front end of outer heat-shrinkable T bush exceeds heart yearn solder joint front end certain distance, the rear end of outer heat-shrinkable T bush 15 exceeds patchcord bending head certain distance.Video line is bent stress point and moves to position away from heart yearn solder joint place by this adapter coupling structure, thus the situation preventing adapter coupling to rupture at heart yearn solder joint place occurs, and enhances the ability of video line exchanging structure bend resistance deformation.
In the present embodiment, in order to strengthen the protection to heart yearn solder joint further, be also provided with interior heat-shrinkable T bush 14 outward at heart yearn solder joint.
In the present embodiment, the shielding conductor joint 12 of video line together with the weld of shielding patchcord 22 after put interior heat-shrinkable T bush 13, part and the shielding conductor pad portion of the corresponding outer heat-shrinkable T bush of shielding conductor joint 12 are all in outer heat-shrinkable T bush 15, in other embodiments, then can select to be in outside outer heat-shrinkable T bush.
