Description
Technical field
The invention belongs to dynamo-electric manufacturing field, particularly a kind of binding post that is applicable on the flame-proof switch.
Background technology
Binding post is to be used for the vitals that the flame-proof switch external cable is connected with internal wiring, and its wiring that is fixed on the explosion-proof electric apparatus switch receives on the fixed head between chamber and the main chamber, in traditional terminal that continues; Conducting rod be screw rod with a brass material in insulating sleeve by the pressing plate of two bolts on the limit through the top, cable clamp is fixed therein, contact-making surface is less relatively; Be difficult for gripping firmly; And resistance is increased, add in the traditional wired post to make that by the conducting rod of two sections copper spares the resistance of conducting rod is bigger through being threaded; Cause binding post to generate heat easily or burn out, the safety of products reliability reduces.
Summary of the invention
For overcoming above-mentioned defective, the invention provides a kind of be used on the flame-proof switch can improve the product safety reliability and resistance is less, be difficult for the binding post of heating.
A kind of binding post that is used on the flame-proof switch comprises: panel nut, pressing plate, screw, conducting block, insulating sleeve, anti-plate, terminal block, insulating cell, clamp nut, conductive strips, hold-down nut, the conducting rod turned round; Conducting rod is by the moulding of red copper material time processing; Its head is square, and the clamping end face of square block is provided with arc groove, and conducting rod is positioned at the center of conducting block and insulating sleeve; The tail end of insulating sleeve passes to be prevented turning round the hole on plate, terminal block and the insulating cell, and insulating cell and terminal block are fixed; The tail end of conducting rod is provided with screw thread, and is fastening to conductive strips through clamp nut and hold-down nut; One end of binding post is provided with screw, and an end of screw is connected with conducting block, and the other end is provided with pressing plate, through the panel nut on the screw, hold the external cable wire clamp in the arc groove of the square head portion end face that is fixed on conducting rod with pressing plate between form and firmly be connected; It is corresponding with the square toes end arc connected in star of conducting rod that pressing plate is provided with arc-shaped concave.
Adopt the present invention that cable is connected firmly, electric conductivity is good, is not easy because of heating binding post to be burnt to cause accident, has improved the security reliability of flame-proof switch.
Description of drawings
Fig. 1 is the structural representation of binding post of the present invention.
Among the figure, the 1-panel nut; The 2-pressing plate; 3-external cable line; The 4-screw; The 5-conducting block; The 6-insulating sleeve; The anti-plate of turning round of 7-; The 8-terminal block; The 9-insulating cell; The 10-clamp nut; The 11-conductive strips; The 12-hold-down nut; The 13-conducting rod.
Embodiment
With reference to Fig. 1 the binding post that is used on the flame-proof switch of the present invention is detailed below.
A kind of binding post that is used on the flame-proof switch comprises: panel nut 1, pressing plate 2, external cable line 3, screw 4, conducting block 5, insulating sleeve 6, anti-plate 7, terminal block 8, insulating cell 9, clamp nut 10, conductive strips 11, hold-down nut 12, the conducting rod 13 turned round.Conducting rod 13 is by the moulding of red copper material time processing; Its head is square; The clamping end face of square block is provided with arc groove; Conducting rod 13 is positioned at the center of conducting block 5 and insulating sleeve 6, and the tail end of insulating sleeve 6 passes the anti-hole on plate 7, terminal block 8 and the insulating cell 9 of turning round, and insulating cell 9 is fixing with terminal block 8.The tail end of conducting rod 13 is provided with screw thread, and is fastening through clamp nut 10 and 12 pairs of conductive strips 11 of hold-down nut.One end of binding post is provided with screw 4; One end of screw 4 is connected with conducting block 5; The other end is provided with pressing plate 2, through the panel nut on the screw 41, be clamped to external cable line 3 in the arc groove of square head portion end face of conducting rod 13 with pressing plate 2 between form and firmly be connected.It is corresponding with the square toes end arc connected in star of conducting rod 13 that pressing plate 2 is provided with arc-shaped concave.
The conducting rod of this binding post is processed with the red copper of low-resistivity, and its resistivity is 0.018 Ω. ㎜
2/ m, and conducting rod is that brass rod is processed in traditional binding post, its resistivity is 0.071 Ω. ㎜
2/ m, so the red copper conducting rod is littler than the resistivity of brass conductive bar, the electric conductivity of red copper conducting rod is superior to the brass conductive bar, and the moulding of this binding post employing time processing, increases substantially than traditional conducting rod electric conductivity.Avoided seriously generating heat, caused burning out the generation of accidents such as binding post because of poor electric conductivity makes electric pole.
