In the terminal box of above-mentioned a kind of asynchronous motor, described fire-retardant sealing ring adopts elastomeric material to make, and described protective sleeve adopts elastomeric material to make.
In the terminal box of above-mentioned a kind of asynchronous motor, the contact-making surface place of the internal groove side wall of described fire-retardant sealing ring and described line outlet groove is provided with metal washer, and the contact-making surface place of described protective sleeve and described fire-retardant sealing ring is provided with metal washer.
In the terminal box of above-mentioned a kind of asynchronous motor, the end of described outlet section is connected with hickey.
Compared with prior art, the terminal box of this asynchronous motor has the following advantages:
1, in the box body inner chamber, terminal block is set, be fixed with binding post on the terminal block, utilize two of binding post to bring in upper strata power line in the connecting box intracoelomic cavity and the lower floor's power line in the box body inner chamber, so that power line marshalling in the box body inner chamber has advantages of that power line interferes with each other.
2, adopt the sealing positioning component that the power line of drawing from box body inner chamber upper strata is sealed fixing, avoided power line easily to be pulled the problem of pulling apart, have advantages of that also the box body of preventing inner chamber makes moist simultaneously.
