Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model electric automobile cabinet power terminal embodiment.
Fig. 2 is the generalized section of power terminal in Fig. 1.
Fig. 3 is the schematic diagram that in Fig. 1, electric automobile cabinet power terminal is installed to cabinet.
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.
As shown in Figure 1, 2, be the schematic diagram of the utility model electric automobile cabinet power terminal embodiment, it can realize the electrical connection inside and outside cabinet under the prerequisite that does not affect electric automobile cabinet sealing.This power terminal comprises insulation crust 11, copper post 12, nut 13 and wiring nose 14, wherein insulation crust 11 comprises Plug Division, fixed part and runs through Plug Division and the through hole of fixed part, wherein Plug Division be connected with fixed part (for example Plug Division and connecting portion can be integrated), and the size and dimension of Plug Division mates with the terminal installing hole on cabinet, and the size of fixed part is greater than the size of the terminal installing hole on cabinet; The first end of copper post 12 has external screw thread, the second end and has the connecting portion of size that size is greater than the through hole of insulation crust; The first end of copper post 12 from fixed part one side of insulation crust 11 penetrate through hole and from the Plug Division of insulation crust 11 passes, be spirally connected with nut 13, outside fixed part that the second end is stuck in insulation crust 11 and be connected with wiring nose 14.
Above-mentioned insulation crust 11 can be used resistant to elevated temperatures plastics or Machining of Ceramics to form, and it can realize the electrical isolation of copper post 12 and electric automobile cabinet.Copper post 12 is stuck in outside the fixed part of insulation crust 11 by the step surface of connecting portion, and is locked on insulation crust 11 by the nut 13 of the other end.
Above-mentioned electric automobile cabinet power terminal is separated copper post 12 and cabinet 20 by insulation crust 11, by nut 13, copper post is locked in insulation crust 11 simultaneously, thereby can realizes the inside and outside stable electrical connection of cabinet 20 by copper post 12.
Especially, as shown in Figure 1,3, above-mentioned power terminal is realized in the following manner the electrical connection with copper bar 21 in cabinet: in the end of copper bar 21, connecting hole is set and the first end of copper post 12 is spirally connected with a hold-down nut 22 through after above-mentioned connecting hole, thereby copper bar 21 is clamped between hold-down nut 22 and nut 13.Correspondingly, because the first end of copper post 12 must be spirally connected with two nuts, therefore the externally threaded length of these copper post 12 first ends need be greater than the height of two nuts, and the length that passes from the through hole of insulation crust 11 of the first end of copper post 12 is greater than the height of two nuts.
Certainly, in actual applications, the first end of copper post 12 also can be electrically connected to copper bar 21 by other means.
For guaranteeing the sealing property of cabinet 20, can the first sealing ring 15 be set in the side towards Plug Division of the fixed part of insulation crust 11, this first sealing ring 15 is around Plug Division, and compress and be arranged between insulation crust 11 and cabinet 20, thereby guarantee the sealing between insulation crust 11 and cabinet 20 when insulation crust 11 is fixed to cabinet 20.
In addition, between the first end of copper post 12 and the second end, be provided with the second sealing ring 16 can be set, this second sealing ring 16 is set on copper post 12, and when copper post 12 is inserted into the through hole of insulation crust 11, be pressed between the inwall of through hole of copper post 12 and insulation crust 11, guarantee the sealing between insulation crust 11 and copper post 12.
On the connecting portion of the second end of copper post 12 and wiring nose 14, corresponding screw can be set respectively, thus can be fixing by being screwed onto electrical connection and machinery that two screws on screw realize between copper post 12 and wiring nose 14.Also can on wiring nose 14, establish through hole, at the connecting portion of copper post 12, screw is set, screw is screwed to through the through hole of wiring nose 14 electrical connection and the machinery that the screw of the connecting portion of copper post 12 realizes between copper post 12 and wiring nose 14 and fixes.Certainly, in actual use, being connected and fixed between copper post 12 and wiring nose 14 also can adopt other existing modes.
For improving the electrical connection performance between copper post 12 and wiring nose 14, can make the connecting portion of copper post 12 and the contact portion of wiring nose 14 lower surfaces is plane.
Above-mentioned insulation crust 11 can be fixed by screws on cabinet 20.For avoiding colliding for insulation crust 11 being fixed to screw and the wiring line nose 14 of cabinet 20, the fixed part of insulation crust 11 is provided with the shrinkage pool 111 that hold-down screw is installed, thus the fail safe that improves whole power terminal.
The above; it is only preferably embodiment of the utility model; but protection range of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; 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 as the criterion with the protection range of claim.
