Fig. 3 is the structural representation of the utility model conductive electrode.
In figure:1- insulators, 2- conductive electrodes, 3- cables, 4- counterbores A, 5- counterbore B, 6- through hole, 7- binding posts, 8- are conductive Contact pin.
Embodiment
The technical solution of the utility model is described further below in conjunction with accompanying drawing, but required protection domain is not It is confined to described.
The utility model provides a kind of electric connector, as shown in Figure 1 and Figure 2, including insulator 1 and multiple conductive electrodes 2, One end of insulator 1 is provided with multiple counterbore A4, and through hole 6, one end connecting cable 3 of conductive electrode 2, conductive electrode 2 are provided with counterbore A4 The other end be set in through hole 6.Using electric connector provided by the utility model, conductive electrode 2 is set in through hole 6, phase Creep age distance between adjacent conductive electrode 2 is extended the distance between length and adjacent conductive pole of insulator by conductive electrode and determined, The length of conductive electrode 2 or counterbore A4 depth, you can the creep age distance between regulation adjacent conductive pole 2, regulation counterbore A4 depth Degree, which needs only to change electric connector, prepares mould, for example, conductive electrode 2 is stretched out the height of insulator 1 improves 5 millimeters, this Shi Ze makes the creep age distance between electric connector adjacent conductive pole accordingly add 10 millimeters, accounts for the 1/4 of total creep age distance, and Electric connector after improvement is completely compatible with original electric connector in stress levels, specified current-carrying, performance etc.,
The end face of the side of insulator 1 is additionally provided with counterbore B5, and counterbore B5 bottom connects with through hole 6.Further, counterbore B5 It is respectively arranged at two end faces of insulator 1 with counterbore A4, counterbore B5 and counterbore A4 ground are interconnected by through hole 6.
Conductive electrode 2 is made up of binding post 7 and conductive pin 8, and one end of binding post 7 is connected with cable 3, binding post 7 it is another One end connects as one through through hole 6 with conductive pin 8.
Binding post 7 is connected through a screw thread mode and connected as one with conductive pin 8.
As shown in figure 3, using the technical scheme, because the conductive electrode 2 of electric connector is Split type structure, including binding post 7 With conductive pin 8, cable 3 is connected to one end of binding post 7, and the other end of binding post 7 is connected through a screw thread mode and inserted with conduction Pin 8 links together, and makes the creep age distance between regulation electric connector adjacent electrode more convenient, fast, it is thus only necessary to adjust The reach screwed between binding post 7 and conductive pin 8 can be such that conductive pin 8 changes relative to the difference in height of insulator 1, So as to change the creep age distance between electric connector adjacent conductive pole 2.
Further, counterbore A4 depth is not less than 10 millimeters.Using the technical scheme, be advantageous to further raising and be electrically connected The creep age distance between device adjacent conductive pole 2 is connect, if counterbore A4 depth is less than 10 millimeters, creep age distance is small, if will be electrically connected Device is connect to apply with mining, then the security performance of electrical equipment can be influenceed.
Further, the quantity of conductive electrode 2 is 2 or 3, further, can also configure ground wire 1 on electrical connectors It is individual, phase line 3, spacing 2, line, 6 conductive electrodes altogether, so that the use range of the electric connector is more extensive.
Electric connector is applied to mining equipment, and it is less than 250 amperes by electric current, and both end voltage is less than 1140 volts It is special.Using the technical solution of the utility model, the scope of application of original electric connector is extended, the electric connector after improvement is applicable In air is filthy, in non-coal mine operation equipment of high humidity, improves the usage safety performance of electric connector, changes simultaneously Cause cheap.
