The utility model content
The utility model technical problem to be solved is to the prior art present situation a kind of binding post to be provided, and it can guarantee lead and conduct electricity the good conducting of copper rod, and can significantly save the raw material of conduction copper rod, the reduction product cost.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this binding post; Comprise insulating base, conduction copper rod and line ball screw, wherein, have wiring hole in the insulating base; It is characterized in that: in the wiring hole of said insulating base Wire crimping cap is installed; Wire crimping cap central authorities have the connecting hole that runs through, and said conduction copper rod is inserted among the connecting hole of Wire crimping cap, and the relative insulating base of conduction copper rod is fixed;
Said line ball screw thread is connected the top of Wire crimping cap, and the bottom of line ball screw penetrates into from the top of Wire crimping cap among the connecting hole and props up the top of conduction copper rod.
During practical application, lead is arranged between the bottom of bottom and Wire crimping cap connecting hole of conduction copper rod, the line ball screw of screwing; The relative Wire crimping cap of line ball screw moves down, and owing to the relative insulating base of conduction copper rod is fixed, and the bottom of line ball screw can prop up the top of conduction copper rod all the time; So; The Wire crimping cap that connects with the line ball screw thread will move up relatively, and the related then lead that is arranged in the Wire crimping cap connecting hole moves up, and is last; Wire crimping cap will conduct electricity copper rod with conductor compression jointing, realize both reliable conductings.
Preferably, the cross section of said Wire crimping cap outline is rectangle, and is formed by sheet electric conducting material bending, thereby entreats nature to form the connecting hole that runs through therein, and manufacture craft is simple, convenient.
Preferably, said conduction copper rod is flat.
Further improve; The bottom that said Wire crimping cap is positioned at connecting hole can be provided with a plurality of parallel fins, also correspondingly is provided with sawtooth and said conduction copper rod is positioned at that section bottom of connecting hole, through the design of fin and sawtooth; Can reliably catch lead, prevent that the unexpected slippage of lead from going out Wire crimping cap.
Compared with prior art; The advantage of the utility model is: through being equipped with jointly of Wire crimping cap, conduction copper rod and line ball screw; Wire crimping cap can will conduct electricity copper rod with closely crimping of lead; Enlarged the contact-making surface of lead, can guarantee the good conducting of lead and conduction copper rod with the conduction copper rod; Therefore the more important thing is that the conduction copper rod can be made into the flat that the connecting hole with Wire crimping cap adapts, and has abandoned traditional cylindrical conductive copper rod, has significantly saved the copper raw material, has reduced the cost of product, and is very practical.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Like Fig. 1~shown in Figure 4, this binding post comprises insulating base 1, conduction copper rod 2, line ball screw 3 and Wire crimping cap 4, and among Fig. 1, insulating base 1 is arranged on a side of electronic circuit board 6, and conduction copper rod 2 links to each other with components and parts on the electronic circuit board 6;
Wherein, have many set of connections hole 11 in the insulating base 1, a Wire crimping cap 4 is installed in each wiring hole 11, and supply being connected of conduction copper rod 2 and lead 5;
