Summary of the invention
The purpose of the utility model is: provide a kind of not only insulation effect good, and urban rail transit vehicles motor (subway) terminal box of long service life, to overcome the deficiency of prior art.
In order to achieve the above object; The technical scheme of the utility model is: a kind of urban rail transit vehicles connection box for motor; Comprise housing and end cap, said housing is fixedly connected with end cap is removable, and said housing is provided with cable and penetrates hole and the through hole that is used for wearing motor three-phase line bank; And its: attaching has junction block in the said housing; And junction block is provided with 3 binding posts arranged apart, and each binding post is installed with respectively and is used for the conducting strip that is electrically connected with motor three-phase line bank, and all insulate with junction block through not rotatable nut and be fixedly connected in the bottom of each binding post; In said housing, also be provided with the insulation board that is used for fixing motor three-phase line bank, said insulation board is through being fixedly connected with housing and being arranged in parallel with junction block.
In above-mentioned technical scheme, said junction block has 4 partitions, and each binding post is between adjacent partitions.
In above-mentioned technical scheme, also comprise the sealing shroud that is sleeved on the cable, said sealing shroud penetrates the hole with said cable and is equipped with mutually; The inboard that said motor three-phase line bank wears through hole is respectively equipped with the insulation glue-line, and said motor three-phase line bank passes the insulation glue-line respectively.
The good effect that the utility model had is: because after adopting the utility model said structure; Motor three-phase line bank is electrically connected with the three phase connection of cable through the conductive plate on the binding post respectively, and the three phase connection of cable is fixed on the binding post, not only can effectively prevents the phenomenon that the three phase connection appearance of cable is become flexible; And can guarantee the mutually insulated of cable three phase connection; Junction block through the utility model substitutes expensive insulator in the existing structure, has reduced the production cost of the utility model, and not only insulation effect is good; And long service life, be applicable to production in enormous quantities.Realized the purpose of the utility model.
