As Fig. 2,3, be the electric connection mode of existing conducting rod 1 with conductive clip 2.Conducting rod 1 is a cylindrical conductive post, and conductive clip 2 is provided with a conducting rod fixing hole 21, described conducting rod fixing hole 21 is fluting on one side, be through with a threaded fastener 10 in described conductive clip 2 fluting sides, after threaded fastener 10 and fastening nuts, the part of the groove both sides on conductive clip 2 is drawn close mutually, causes that the outside of conducting rod fixing hole 21 is tightened up, and clamps conducting rod 1.Above-mentioned conducting rod 1 and the electric connection mode of conductive clip 2, transmit fastening force owing to being combined tractive effort by the metal of conducting rod fixing hole 21 between threaded fastener 10, and conductive clip 2 is generally pure copper material, plastic deformation easily occurs in it, conduction efficiency is low, fastening weak effect.Secondly binding thread securing member 10 needs two fastened tools with nut, can not realize one-handed performance.
The utility model content
The utility model provides for the deficiencies in the prior art a kind of connection is more reliable, conduction efficiency is higher, fastening effect excellent, use is convenient conductive clip and moved end electric connection structure.
The utility model is achieved through the following technical solutions:
The electric connection structure of a kind of conductive clip and conducting rod, it comprises conducting rod, conductive clip and threaded fastener, described conductive clip is provided with the conducting rod fixing hole that matches with the conducting rod profile, on conductive clip and be positioned at described conducting rod fixing hole outside and be provided with a screwed hole, screwed hole coordinates with described threaded fastener, and the end of described threaded fastener and conducting rod realize that pushing is fastening.
Be positioned on described conductive clip on the conducting rod fixing hole and corresponding described screwed hole is provided with a compressing tablet, described compressing tablet is between described end and described conducting rod.
Described end is round cap shape.
Described end contacts with described conducting rod.
Described threaded fastener is screw.
Described elastic pressuring plate and conductive clip one consist of.
The beneficial effects of the utility model are:
End and the conducting rod pushing fastening electric connection mode of the utility model by threaded fastener makes the conductive clip of easy generation plastic deformation obtain protection, extends its useful life, improved simultaneously conduction efficiency; Push fastening operation more convenient, one hand can operate; Pushing the fastening fastening force that makes can act directly on conducting rod, and does not need to come excessive tightness power by the material of conductive clip in conjunction with tractive effort, thereby good fastening effect is provided; The design of elastic pressuring plate and circular-arc end face has enlarged the pushing fastening surface with conducting rod, compresses effect excellent, contacts better.
