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.
