Abstract
The utility model discloses a kind of enclosed type bus duct expansion box, it is related to bus duct expansion box technical field.It includes expansion box base, expansion plate, expansion box footstock and telescopic joint fixed plate, expansion plate is provided between expansion box base and expansion box footstock, expansion plate is fixed on expansion box by telescopic joint fixed plate.The utility model the utility model realizes safety telescopic between copper bar, is prevented effectively from the generation of internal force between copper bar, and telescopic joint sealing property is high, effectively control junction temperature rise.
Description
Technical field
The utility model relates to bus duct expansion box technical field, and in particular to a kind of enclosed type bus duct stretches
Case.
Background technology
The design that traditional bus duct expansion box is used is：Perforate and connect on copper bar, shell is simple parcel, close
Envelope property is poor, and safety coefficient is low, poor, junction temperature rise of being insulated between row, greatly reduces the service life of expansion box.
In summary, the utility model devises a kind of new enclosed type bus duct expansion box.
Utility model content
In view of the shortcomings of the prior art, the utility model purpose is to be that providing a kind of enclosed type bus duct stretches
Case, realize being flexible coupling between copper bar, ensure slippage between copper bar, improve the sealing of telescopic joint, improve telescopic joint discharge effect,
Improve telescopic joint service life.
To achieve these goals, the utility model is to realize by the following technical solutions：Enclosed type bus duct is stretched
Contracting case, including expansion box base, expansion plate, expansion box footstock and telescopic joint fixed plate, expansion box base and expansion box footstock it
Between be provided with expansion plate, expansion plate is fixed on expansion box by telescopic joint fixed plate.
Preferably, described expansion plate is arranged on the narrow side of expansion box.
Preferably, described expansion plate two ends connect expansion box base and expansion box footstock respectively.
The beneficial effects of the utility model：The utility model realizes safety telescopic between copper bar, is prevented effectively from copper bar
The generation of power, telescopic joint sealing property is high, effectively control junction temperature rise.
Brief description of the drawings
Describe the utility model in detail with reference to the accompanying drawings and detailed description；
Fig. 1 is structural representation of the present utility model.
Embodiment
To be easy to understand technological means, creation characteristic, reached purpose and effect of the utility model realization, below
With reference to embodiment, the utility model is expanded on further.
Reference picture 1, present embodiment uses following technical scheme：Enclosed type bus duct expansion box, including expansion box
Base 1, expansion plate 2, expansion box footstock 3 and telescopic joint fixed plate 4, are provided between expansion box base 1 and expansion box footstock 3 and stretch
Contracting plate 2, expansion plate 2 is fixed on expansion box by telescopic joint fixed plate 4.
It is worth noting that, described expansion plate 2 is arranged on the narrow side of expansion box.
In addition, the described two ends of expansion plate 2 connect expansion box base 1 and expansion box footstock 3 respectively.
The expansion box of present embodiment uses telescopic joint (expansion plate), solves copper bar caused by expanding with heat and contract with cold small
Motion makes to produce extruding force, the sealing of telescopic joint, the conductive stability of telescopic joint, the connection of telescopic joint, telescopic joint peace between copper bar
Holding position is selected, insulating between flexible row, the point discharge of flexible row the problems such as.
Present embodiment realize being flexible coupling between copper bar, the sealing for ensureing slippage between copper bar, improving telescopic joint,
Improve telescopic joint discharge effect, improve telescopic joint service life.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
