In some embodiments of the invention, as shown in Figure 2, the outer end 2A being positioned at outside cover plate 200 of connecting rod 2 is provided with outer end threaded fastener assembly 4, and the wiring compressing tablet 3 (1) being positioned at the outer end 2A of connecting rod 2 is fixed on the outer end 2A of connecting rod 2 by outer end threaded fastener assembly 4.In addition, the inner 2B being positioned at inside cover plate 200 of connecting rod 2 is provided with inner threaded fastener assembly 5, and the wiring compressing tablet 3 (2) being positioned at the inner 2B of connecting rod 2 is fixed on the inner 2B of connecting rod 2 by inner threaded fastener assembly 5.
Here, wiring compressing tablet 3 is formed as annular or semi-circular, is enclosed within connecting rod 2 outside wiring compressing tablet 3, thus makes the electrical connection between wiring compressing tablet 3 and connecting rod 2 simple, direct.
Particularly, the outer end 2A of connecting rod 2 and inner 2B has flank respectively, make outer end threaded fastener assembly 4 and inner threaded fastener assembly 5 can coordinate to be connected on connecting rod 2 respectively by with above-mentioned flank, so that wiring compressing tablet 3 is fixed on connecting rod 2, thus make wiring compressing tablet 3 be removably mounted on connecting rod 2, the fixation procedure of wiring compressing tablet 3 is simple, easily, and then shortens the installation time of lead-in wire ejector 100.
In a concrete example of the present invention, as shown in Figure 2, outer end threaded fastener assembly 4 comprises the first nut 41 and the second nut 42, first nut 41 is threaded with connecting rod 2 respectively with the second nut 42, and the wiring compressing tablet 3 (1) be positioned on the outer end 2A of connecting rod 2 is clamped between these two nuts by the first nut 41 and the second nut 42.Wherein, the first nut 41 is connected with tapered plug 1, and the second nut 42 is connected with the first nut 41, and namely the second nut 42 is positioned at the side away from tapered plug 1 of the first nut 41.
The wiring compressing tablet 3 (1) be positioned on the outer end 2A of connecting rod 2 is clipped between the first nut 41 and the second nut 42, wiring compressing tablet 3 (1) stress deformation can be avoided, and facilitate wiring compressing tablet 3 (1) to be connected with outer leg 301.
In a concrete example of the present invention, as shown in Figure 2, inner threaded fastener assembly 5 comprises the 3rd nut 52 and boss 51, and boss 51 is located on connecting rod 2, and the wiring compressing tablet 3 (2) being positioned at the inner 2B of connecting rod 2 is fastened between the 3rd nut 52 and boss 51 by the 3rd nut 52.Wherein, boss 51 is connected with tapered plug 1, and the 3rd nut 52 is connected with boss 51, and namely the 3rd nut 52 is positioned at the side away from tapered plug 1 of boss 51.
The wiring compressing tablet 3 (2) be positioned on the inner 2B of connecting rod 2 is clipped between the 3rd nut 52 and boss 51, wiring compressing tablet 3 (2) stress deformation can be avoided, and facilitate wiring compressing tablet 3 (2) to be connected with inner leads 302.
Particularly, as shown in Figure 3, boss 51 is stretched from the portion perimeter facing epitaxy of connecting rod 2, and boss 51 and connecting rod 2 form as one part.The setting of boss 51, makes inner threaded fastener assembly 5 tightly be connected on the inner 2B of connecting rod 2, avoids boss 51 to get loose and causes wiring compressing tablet 3 (2) to drop.And the cooperation of boss 51, connecting rod 2 and the first nut 41, tapered plug 1 is clamped between boss 51 and the first nut 41 tightly.When tapered plug 1 has certain elasticity, tapered plug 1 is subject to the thrust of boss 51 and the first nut 41, and the elastic force of tapered plug 1 also can act on the first nut 41, and the first nut 41 is not easily got loose.Thus, the reliability that connecting rod 2 is connected with tapered plug 1 can be ensured, avoid connecting rod 2 to get loose and cause connecting hole 11 place to be leaked.
Further, as shown in Figure 3, between the first nut 41 and tapered plug 1, pad 6 is respectively arranged with between boss 51 and tapered plug 1.Thus, the sealing of lead-in wire ejector 100 can be ensured further.
