Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in figures 2-6, be the schematic diagram of frequency converter terminal embodiment of the present invention.Frequency converter terminal in the present embodiment comprises the body 21 be made up of insulating material, is provided with longitudinal bolt containing cavity 23 (bolt be namely placed in this bolt containing cavity 23 is longitudinally arranged in body 21) and this body 21 is also provided with the bolt hole 24 (bolt being namely placed in this bolt hole 24 is horizontally through body 21) being horizontally through this body 21 in this body 21.
Particularly, above-mentioned bolt containing cavity 23 can perpendicular to the front of binding post, and bolt hole 24 then can perpendicular to the side of binding post.
In addition, on body 21, two terminal fixation hole 22 (this terminal fixation hole and bolt containing cavity 23 are in the same way) also can be set, thus this binding post is fixed on frequency converter by the screw through terminal fixation hole 22.
Bolt containing cavity 23 is for placing bolt, and this bolt can be combined with nut, realizes the copper bar in binding post front or being connected and fixed of cable.Above-mentioned bolt containing cavity 23 comprise be positioned at body lower part bolt head holding part 231 and the stud holding part 232 that extended up to by bolt head holding part 231 outside body 21.Especially, the size of above-mentioned bolt head holding part 231 is greater than the size of bolt head, and the size of stud holding part 232 is between stud and the size of bolt head, thus when the bolt fixing copper bar or cable is placed in bolt containing cavity 23, can only be movable in bolt containing cavity 23, and can not come off from bolt containing cavity 23.
Bolt hole 24 can supply bolt (shaft) to pass, and to realize the fixing of the copper bar of binding post side or cable, wherein the diameter of the mid portion of this bolt hole 24 is less than the diameter of bolt head and is greater than the diameter of stud.Especially, for reducing the size of frequency converter terminal, bolt hole 24 can be made through bolt containing cavity 23, as shown in Figure 5.
In above-mentioned frequency converter terminal, body 21 comprises two side plates 26 and the copper bar stationary plane 25 between two side plates.The top of bolt containing cavity 23 is positioned at copper bar stationary plane 25, and namely the top of stud holding part 232 is positioned at the copper bar stationary plane 25 in binding post front.Bolt hole 24 is positioned at below copper bar stationary plane.
As shown in Figure 7, be realize the fixing schematic diagram of front copper bar by the frequency converter terminal in Fig. 2-6.First bolt 50 is placed in the bolt containing cavity 23 in body 21, and the top of bolt 50 is higher than copper bar stationary plane 25, then inner copper bar 40 and external copper bar 30 (it can arrange bolt hole) to be placed in successively on copper bar stationary plane 25 and to use plain cushion or bullet pad to compress, finally nut 60 is screwed to bolt 50, realizes copper bar and fix.Because bolt 50 is in the bolt containing cavity 23 of body 21, and copper bar is placed in the copper bar stationary plane 25 of body 21, and therefore above-mentioned binding post not only achieves copper bar support, and is firmly fixed on binding post by copper bar, avoids copper bar and comes off.
As shown in Figure 8, be realize the fixing schematic diagram of side copper bar by the frequency converter terminal in Fig. 2-6.First (diameter due to bolt head is greater than the diameter of the mid portion of bolt hole 24 to make bolt 50 penetrate bolt hole 24 from a side of binding post, therefore this bolt entirety can not pass bolt hole 24), then the side (side relative with bolt head) inner copper bar 40 and external copper bar 30 (it can arrange bolt hole) being placed in successively binding post is gone up and uses plain cushion or bullet pad to compress, finally nut 60 is screwed to bolt 50, realizes copper bar and fix.
The one or both ends of above-mentioned bolt hole 24 can arrange the bolt head socket that size is greater than bolt head, thus the bolt head of bolt 50 can be embedded in body 21.Deviate from from the bolt head socket of bolt hole 24 in order to avoid bolt 50, elastic hook 241 can be set at the body 21 of binding post, this elastic hook 241 near binding post sidewall and be positioned at the bolt head socket place of bolt hole 24, as shown in Figure 9.
As shown in Figure 10, the body 21 of above-mentioned frequency converter terminal can be put together by the component 211 that two structures are identical, each component 211 has half bolt containing cavity 23 and half section of bolt hole 24, and namely each component 211 is by longitudinal for bolt containing cavity 23 dimidiation.
For realizing being fixedly connected with of two components 211, hole clipping (not shown) and card column 213 can be set at the end face of each component 211, thus realize the split of two components 211 by hole clipping and card column 213.
For preventing the bolt in bolt containing cavity 23 from coming off from body 21, seam can be set in the bottom of the body 21 of binding post.Especially, the seam of the bottom of each component 211 above-mentioned comprises recess and protuberance 212, and when two component 211 splits, the protuberance 212 of one of them component 211 inserts the recess of another component 211, as shown in figure 11.
For realizing the stable fixing of copper bar, the body 21 of each frequency converter terminal can be arranged respectively two bolt containing cavities 23 side by side and two bolt holes 24 side by side.Certainly, in actual applications, bolt containing cavity 23 and two bolt holes 24 can be increased or reduce as required.
The above; be only the present invention's preferably embodiment, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
