Abstract
Disclosed is a D-type modified copper bar including a straight line portion and an arc portion. The arc portion and the straight line portion are in smooth connection. The central portion of the arc portion is provided with an opening. The arc portion is provided with an opening structure, the generation of an eddy current is effectively blocked, the amount of heat when power is applied is reduced, and the energy utilization is improved. In addition, the use of the opening structure allows copper bar materials to be saved and production costs to be reduced.
Description
Technical field
The utility model relates to a kind of electrician's copper bar.
Background technology
Copper bar is a kind of conducting heavy current product, and its effect is collect, distribute and transmit electric energy.The cross sectional shape of existing copper bar is typically designed to rectangle, circle and D type etc.Wherein, existing D type copper bar is the structure of remaining silent, and in the time of energising, can produce current vortex, produces more heat transfer, increase electric loss of energy, and the design of this closed copper bar is unfavorable for saving material.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of D type transformation of the way copper bar is provided, and its utilization rate of electrical is high, saves material.
For achieving the above object, the utility model is by the following technical solutions:
A kind of D type transformation of the way copper bar, comprises line part and curved portions, described curved portions and described line part smooth connection, and described curved portions middle part is opening.
Preferably, described extended distance is the 1/5-2/5 of described line part length.
Preferably, the thickness of described curved portions equals the thickness of described line part.
Preferably, the thickness of described curved portions is less than the thickness of described line part.
Preferably, the thickness of described curved portions is 5mm, and the thickness of described line part is 8mm.
Adopt after technique scheme, the utility model is compared with existing background technology, and tool has the following advantages:
1, the curved portions of the utility model copper bar is hatch frame, has effectively blocked the generation of current vortex, and the thermal discharge while reducing energising, has improved utilization rate of electrical.
2, hatch frame is saved copper bar material, reduces production costs.
Brief description of the drawings
Fig. 1 is the sectional view of the utility model embodiment mono-;
Fig. 2 is the sectional view of the utility model embodiment bis-.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment mono-
As shown in Figure 1, the utility model discloses a kind of D type transformation of the way copper bar, comprise line part 1 and curved portions 2, curved portions 2 and line part 1 smooth connection, the thickness of curved portions 2 equals the thickness of line part 1.Curved portions 2 middle parts are opening 21, and making the utility model overall appearance is opening D type copper bar.Opening 21 distances are the 1/5-2/5 of line part 1 length.Curved portions 2 is hatch frame, has effectively blocked the generation of current vortex, and the thermal discharge while reducing energising, has improved utilization rate of electrical.And hatch frame is saved copper bar material, reduces production costs.
Embodiment bis-
As shown in Figure 2, the difference of the present embodiment and embodiment mono-is, the thickness of curved portions 2 is less than the thickness of line part 1.If the thickness of curved portions 2 is 5mm, the thickness of line part 1 is 8mm.The thickness of curved portions 2 is less than the thickness of line part 1, can further reduce copper bar material, reduces production costs.
The above; it is only preferably embodiment of the utility model; but protection range of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be with the protection range of claim.
