Abstract
The utility model discloses a double-bolt bus duct comprising a shell and a plurality of terminal splices, wherein the terminal splices are arranged in parallel and are installed in the shell through a fixed plate, two ends of each terminal interface extend to the outer parts of two sides of the shell, and the extending parts of the two ends of the terminal interface are provided with a pair of bolt positioning holes. In the utility model, a double-bolt clamping structure is adopted to lead the connection between the bus ducts to be more stable and reliable so as to improve the use safety of the bus ducts.
Description
Technical field
The utility model relates to a kind of plug type bus duct that is used for power transmission and distribution, especially relates to a kind of pair of bolt bus duct.
Background technology
Bus duct be substitute cable in the conventional art and crane span structure for power distribution equipment, modern high-rise building and large-scale workshop need huge electric energy, will select safe and reliable transmission equipment for use and face the required hundreds and thousands of amperes powerful electric current of this huge load, bus-bar system will be desirable selection, bus duct system is an efficient power distribution equipment of carrying electric current, especially the needs that adapted to more and more higher building and large-scale plant economical rationality distribution have safe and reliable, easy for installation, construct flexible, the little and capacious characteristics of volume usually.But the major defect of existing bus duct is: the operation that tends to cause because of its special construction implementation process generation mistake when connecting is being installed, and a bolt is only used in the junction, the stability that this greatly reduces bus duct exists certain potential safety hazard.Therefore be necessary to be improved.
The utility model content
The purpose of this utility model is the weak point at the prior art existence, and a kind of two bolt bus ducts firm, safe in utilization that connect are provided.
To achieve these goals, the technical solution adopted in the utility model is: comprise shell body and plurality of terminals contact pin, described terminal tab be arranged in parallel and is installed in the shell body by fixed head, the two ends of described terminal tab extend outside, shell body both sides, and the extension at described terminal tab two ends is equipped with the pair of bolts location hole.
The spigot of described shell body is provided with protective plate.
Described shell body is provided with some installing holes.
The beneficial effects of the utility model are: adopt two bolt clip locking structures can make the connection between the bus duct more solid and reliable, thereby improve the fail safe that bus duct uses.
Description of drawings
Fig. 1 is the structural representation of the two bolt bus ducts of the utility model.
Fig. 2 is the connection diagram of described pair of bolt bus duct of the utility model embodiment.
Embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection range of the present utility model.
Referring to Fig. 1 and Fig. 2, a kind of pair of bolt bus duct that newly provides according to this practicality, comprise shell body 1 and plurality of terminals contact pin 2, described terminal tab 2 be arranged in parallel and is installed in the shell body 1 by fixed head, the two ends of described terminal tab 2 extend outside, shell body 1 both sides, the extension at described terminal tab 2 two ends is equipped with pair of bolts location hole 4, the spigot of described shell body 1 is provided with protective plate 3, have only when protective plate 3 draws back, jack box could insert, and jack can be added along locked by protective plate 3 when idle and closes to prevent entering at spigot dust and foreign matter; When two bus duct unit are connected, fastening by the location hole 4 usefulness plugboards 6 that a pair of set bolt 5 passes on the terminal tab 2; Described shell body 1 is provided with some installing holes 7.
