Embodiment
Come the present invention is done further detailed explanation below in conjunction with accompanying drawing and specific embodiment.
Shown in Fig. 3-4, the present invention provides a kind of stator terminal box of wound rotor motor, comprises junction box seat, connector cover; Described connector cover is installed on the junction box seat, and is installed on the patch board device in the junction box seat, and said patch board device comprises a plurality of parallel connected terminal blocks 5; Installation connection post 2 on said each terminal block 5; Two terminals of said binding post 2 are hierarchy, and two terminals of said binding post 2 connect through flow deflector 3, and here junction box seat and connector cover promptly are shells; Playing the effect of protection, all is often to use in the prior art.
In the present invention; Being shaped as of said binding post 2 is L shaped; Two ends of said L shaped binding post 2 lay respectively at the end face and the end face of said terminal block 5, and the middle-end of said L shaped binding post 2 is positioned at said terminal block 5, through above-mentioned structure; Can make two terminals (that is: motor wiring and terminal block) of motor, make wiring easy for installation respectively at the diverse location of same L shaped binding post 2; Wherein, 2 L shaped binding posts 2 are installed respectively on said each terminal block 5, are laid respectively at two ends of said terminal block 5.
Equally, flow deflector 3 matches with L shaped binding post 2, and the shape of described in the present invention flow deflector 3 also is L shaped, and two ends of said L shaped flow deflector 3 are installed on two terminals of L shaped binding post 2 respectively through nut 4.
Further, link to each other through brace 1 between described a plurality of parallel terminal blocks 5, said brace 1 is installed on the binding post 2 of said each terminal block 5 end face; Said brace 1 is installed on the binding post 2 of said each terminal block 5 end faces one end through nut 4, and said brace 1 is positioned at the upper end of said flow deflector 3; The bottom surface of described each terminal block 5 also is provided with groove; Installation connection plate erecting bed 6 in the said groove; Said terminal block erecting bed 6 is installed some stay pipes 7, and the other end of said stay pipe 7 is installed erecting bed 8, and the height of stay pipe 7 has guaranteed the space of motor wiring.
In order better to realize effect of the present invention, the quantity of wherein said stay pipe 7 is identical with the quantity of said terminal block 5; The material of said terminal block 5 is the BMC unsaturated polyester (UP).
And in the present invention, the quantity of described terminal block 5 is 3, can as required the quantity of terminal block 5 be changed equally.
When concrete the use; Owing to will comprise a plurality of parallel connected terminal blocks 5, make any one terminal block 5 damage the back and only change the terminal blocks 5 that damage and need not to change all terminal blocks 5, and two terminals that binding post 2 is set are the layering wiring; That is: two ends of L shaped binding post 2 are laid respectively at the end face and the end face of said terminal block 5; The motor wiring is connected with two terminals of L shaped binding post 2 respectively with terminal block, has made things convenient for user's wiring problem
In the stator terminal box of wound rotor motor of the present invention; When flow deflector 3 not being installed making an experiment; Because of motor terminal block 5 because of stator current fully through wrapping in binding post 2 in the BMC unsaturated polyester (UP) cause terminal block 5 to burn because the heat that passes through to produce of electric current distributes not go out.
