General binding post; for often adopting finger to screw mode (especially being common in the connection between AV), convenience binding post can't be locked; if electric wire is stirred slightly or is vibrated; then terminal and binding post very easily get loose; contact impedance is raise, transmission is bad, also can produce spark and cause disaster; seeing also the forked type plug of Fig. 1, is the joint A1 at front end moulding one bifurcated of plug A main body, and this kind plug A coats a sheath B to protect the fixing position of itself and lead in body exterior.

Above-mentioned prior art binding post is to be the so design of having to of contact and socket; but cause some problems that can't overcome to those skilled in the art: the joint A1 of this plug A front end is made as combining of rigidity with the spiral shell of the assembly that is spirally connected, so be difficult for establishing closely and regular meeting has the facts of the short circuit of getting loose to take place with the finger spiral shell.

Just the someone develops binding post E shown in Figure 2, it mainly is to be provided with base plate E1, cover plate E2 at binding post E front end, wherein this base plate E1, cover plate E2 are formed by folded the establishing of two lamellar bodies of unlike material, insert flexible washer E3 in base plate E1 and cover plate E2 front end again, one elastic reaction is arranged when being spirally connected for binding post E; There is binding post F shown in Figure 3 to be developed again, this binding post F is combined with a fork shaft bar F2 and is provided with a base plate F3 and an elastomer F4 on contact fork F1 at preceding end in contact fork F1, elastomer F4 is provided with a cover plate F5, when binding post F is subjected to spiral shell to set the position, then form a preferable Vibrant buffer by elastomer F4.

Though the cushioning effect of elastic reaction and mechanical oscillation when stating two kinds of binding post E, F and can provide spiral shell to set the position, when binding post E, F are subjected to pullling of improper external force, also have the problem that slippage goes out terminal spiral clamping part, still have its inconvenience in the use, moreover, environmental protection requirement can reclaim its binding post E, F and found regeneration now, right binding post E, F all produce the facts that is difficult for to reclaiming, because of having the raw material and the elastomeric material of several unlike materials on this binding post E, the F, energy regeneration brings a no small problem so also become now.

[summary of the invention]

Because the prior art plug makes the inventor do an improvement at connection plug for the dealer brings so puzzlement,, at first invented out the present invention then with the plug of improvement prior art.

Main purpose of the present invention is that a kind of binding post is being provided, and to improve the convenience of distribution construction, anti-loose reaching stablized the purpose that contact is not short-circuited.

To achieve the object of the present invention, the technology used in the present invention means are: be between upper and lower surface, the U of binding post front end type Plug Division, to be provided with compression groove, and at the upper and lower formation one upper and lower resilient clamp face of compression groove; The compression groove of the U type Plug Division by the binding post body allows conveniently be spirally connected the assembly spiral shell if upper and lower resilient clamp face produces compressible elastic reaction after plugging the location, and then makes the assembly spiral shell that is spirally connected of binding post top establish more close positioning on binding post; The U type Plug Division thickness of binding post body is greater than the upper and lower resilient clamp end face sum thickness of compression groove.

Technological means through above-mentioned the invention has the beneficial effects as follows: compression groove 21 designs of binding post 1 of the present invention, it is tightr to allow binding post combine with binding post, and then reaches better laser propagation effect.Compression groove 21 formed elastic force effects before the binding post 1 of the present invention can effectively absorb the power that external vibrations or electric wire are stirred, so the assembly D that is spirally connected that is arranged on the compression groove 21 does not have the facts generation that vibrations get loose.Binding post 1 of the present invention is to be the elastic compression combination with combining of binding post C, so do not have the facts generation that loose contact produces spark.The thickness system of U type Plug Division 2 leading sections 22 of binding post 1 of the present invention is much larger than upper and lower resilient clamp end face 200, the 201 thickness sums of compression groove 21, so even the U type Plug Division 2 of binding post 1 is subjected to external force to pull the clamping spacing that also can not skid off the assembly D that is spirally connected, because of this upper and lower clamping spacing is a thickness less than leading section 22.The U type Plug Division 2 of binding post 1 of the present invention is that single material is made, so during environmental friendly regenerated recovery, very convenient.Binding post 1 of the present invention is one-body molded, and no secondary contact is not so can increase contact impedance.
