Abstract
The utility model relates to a cable lead connection structure of a junction box of an explosion-proof blower motor. In the structure, a cable terminal passes through the bottom of the junction box of the blower motor in a position of an insulating sleeve; the lower end of the cable terminal is connected with a cable lead through an O-shaped cable connector and a wire press nut; and insulating sleeves are hermetically cast at the junctions. The structure has the advantages of good explosion-proof and sealing properties, high safety and reliability, and the like, and achieves the effect that the cable connection, the installation and the maintenance are rapid and convenient.
Description
Technical field
The utility model belongs to blower motor appurtenances technical field, is that a kind of flame-proof type blower motor terminal box cable is drawn wiring construction.
Background technology
In known technology, the electric source connecting box of flame-proof type blower motor normally is installed in the outside of Blower Housing by the terminal box bearing, bottom in terminal box is provided with through wires hole, and be coated with binding post by insulating case, the motor outgoing cable is welded on the lower end of binding post, and then connecting portion is carried out insulated enclosure handle.The major defect that this wiring construction exists: the one, threading position sealing is poor, has a strong impact on the explosion insulation performance of blower fan; The 2nd, when keeping in repair, outgoing cable must be cut off, and being welded to connect of binding post can be reconnected after the position is cleared up, time-consuming, labour intensity is big, influences the service efficiency of blower fan; The 3rd, it is loaded down with trivial details that the outgoing cable terminals are carried out insulation processing, and security reliability is difficult for guaranteeing.
The utility model content
The purpose of this utility model provides a kind of flame proof, good seal performance, and is safe and reliable, and the wiring installation, maintenance fast and easily flame-proof type blower motor terminal box cable draw wiring construction.
Realize that the technical scheme that the purpose of this utility model is taked is: this structure is to be coated with the cable connection post in the bottom of blower motor terminal box by the insulating case place, the lower end of cable connection post is connected with outgoing cable with the line ball nut by O type cable joint, and this connecting portion is provided with and waters the envelope insulating case.
Draw wiring construction according to the flame-proof type blower motor terminal box cable that such scheme is made, draw the improvement of the mode of connection and the sealed insulation processing at butted line position by cable, make it compared with prior art have flame proof, good seal performance, advantage such as safe and reliable, and reach wiring installation, maintenance good result fast and easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, flame-proof type blower motor terminal box cable of the present utility model is drawn wiring construction, this structure comprises blower motor terminal box 1 and the terminal box bearing 3 that is wholely set with the blower fan air duct, and terminal box 1 is connected with terminal box bearing 3 with connecting bolt 2 by flameproof joint.Bottom in terminal box 1 is coated with cable connection post 4 by insulating case 5 places, is connected with O type cable joint 7 by the terminals of motor outgoing cable 6, and this O type cable joint 7 is connected with the lower end of described cable connection post 4 by line ball nut 8.Outgoing cable 6 adopts the electric insulating sealant cast to fill in the cavity that terminal box 1 and terminal box bearing 3 are connected to form with after cable connection post 4 is connected, and forms and waters envelope insulating case 5.Can guarantee the good sealing explosion insulation performance in terminal box 1 wiring position like this, simultaneously, only need cut watering of O type cable joint 7 connecting portions and seal insulating case 5 when maintenance, pull down line ball nut 8 and O type cable joint 7, replacing installation back is smeared to fill and lead up with electric insulating sealant at cutting section and is got final product.
Claims (1)
1. a flame-proof type blower motor terminal box cable is drawn wiring construction, it is characterized in that: this structure is to be coated with the cable connection post in the bottom of blower motor terminal box by the insulating case place, the lower end of cable connection post is connected with outgoing cable with the line ball nut by O type cable joint, and this connecting portion is provided with and waters the envelope insulating case.
