Description
Technical field
The utility model 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 the vitals that is connected with internal wiring for the flame-proof switch external cable, its wiring that is fixed on the explosion-proof electric apparatus switch is subjected on the fixed head between chamber and the main chamber, the screw rod that conducting rod adopts a brass material in traditional terminal that continues in insulating sleeve by the pressing plate of two bolts on the limit by the top, cable clamp is fixed therein, the contact-making surface less, be difficult for gripping firmly, resistance is increased, the conducting rod that is threaded connection by two sections copper spares in the traditional wired post simultaneously, so that the resistance of conducting rod is larger, cause binding post easily to generate heat or burn out, the security reliability of product reduces.
The utility model content
For overcoming defects, the utility model provide a kind of 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 for the binding post on the flame-proof switch, mainly comprise: panel nut, pressing plate, external cable line, 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 the anti-hole of turning round 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 by 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, by the panel nut on the screw, the external cable wire clamp is held in the arc groove of the square head portion end face that is fixed on conducting rod, firmly is connected with pressing plate; 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 utility model that inside and outside 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.

Fig. 1 is the structural representation of the utility model binding post.
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
Describe in detail for the binding post on the flame-proof switch described in the utility model below with reference to Fig. 1.
A kind of for the binding post on the flame-proof switch, comprising: 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, the tail end of insulating sleeve 6 passes the anti-hole of turning round on plate 7, terminal block 8 and the insulating cell 9, 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 by 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, by the panel nut 1 on the screw 4, external cable line 3 is clamped 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 made with the red copper of low-resistivity, and its resistivity is 0.018 Ω. ㎜
2/ m and in the traditional binding post conducting rod be that brass rod is made, its resistivity is 0.071 Ω. ㎜
2/ m, so the red copper conducting rod is less than the resistivity of brass conductive bar, the electric conductivity of red copper conducting rod is better than 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 because poor electric conductivity causes electric pole, burnt out the generation of the accidents such as binding post.
