Abstract

The utility model belongs to an inner-connected cell case and an outer-connected cell case for DC electric appliances, composed of a case (1), a cell clamp (2) formed by two positive metal pieces (3) which are respectively sheathed with an insulation sleeve (4) whose facade is provided with a small U-shaped gap and then sheathed with a negative metal piece (5) whose facade is provided with a big U-shaped gap, a positive leading wire (7), a negative leading wire (8), etc. The utility model has simple structure and convenient operation without considering whether the positive and the negative poles of the cell are loaded oppositely even at nights.

Description

Make things convenient for battery case

The utility model belongs to the battery case that a kind of dc electric apparatus uses.

At present, dc electric apparatus generally use in connect battery case and outer connecting battery box, it exists maximum shortcoming and is, its both positive and negative polarity necessarily can not be adorned anti-when packing battery into, otherwise electrical equipment is with regard to cisco unity malfunction.Brought great trouble when therefore, this just gives the electrical equipment user in darkness or at darker local packed battery.

The purpose of this utility model provides a kind of simple in structure, no matter be daytime or night not to need to consider whether battery plus-negative plate is adorned instead during packed battery, use dc electric apparatus use very easily in connect battery case and outer connecting battery box.

The utility model be by box 1, each loads onto insulating case 4 that its front has little " U " v notch v with cathode metal shell fragment 3 cover and overlap and load onto two battery folder 2, positive wire 7, negative wire 8 formations that negative pole metal nest plate 5 that its front has big " U " v notch v is made.

Below in conjunction with accompanying drawing description is made in enforcement of the present utility model.

Fig. 1 is a stereochemical structure partial schematic sectional view of the present utility model.

Fig. 2 is that A-A of Fig. 1 of the present utility model is to cutaway view.

According to Fig. 1, shown in Figure 2, box 1 is an injection molded preferably, and the two ends in box 1 is place, totally four angles, and every place is provided with a draw-in groove 6 that is used to install battery folder 2 perpendicular to box 1 madial wall respectively, and box 1 also can dispose lid.Cathode metal shell fragment 3 is to hollow out into " U " shape word on the rectangle sheet metal preferably an elasticity, and the sheet metal in it is gone out and makes toward excurvation; Edge overlaps 4 extremely and makes and just in time can entangle cathode metal shell fragment 3 and have little " U " v notch v in its front; Negative pole metal nest plate 5 is just in time made and can be entangled insulating case 4 and have big " U " v notch v in its front; Cathode metal shell fragment 3 cover is loaded onto insulating case 4 that its front has little " U " v notch v to be overlapped and loads onto negative pole metal nest plate 5 that its front has big " U " v notch v and compress and just made battery folder 2.Two battery folder 2 making are plugged in 6 li of the draw-in grooves of two ends in the box 1 respectively, respectively the cathode metal shell fragment 3 on two battery folder 2 and negative pole metal nest plate 5 are connected good and draw box 1 with positive wire 7 and negative wire 8 and just obtained the utility model outward.The utility model can make outer connecting battery box and in connect battery case, in the time will making outer connecting battery box, as long as attaching plug is loaded onto in the positive wire 7 outside drawing box 1 and the termination of negative wire 8.

This makes things convenient for battery case, owing to adopted the both sides of two ends box 1 in all not have that two ends is respectively equipped with battery folder 2 so newly designing of all loading onto cathode metal shell fragment 3 and negative pole metal nest plate 5 draw-in groove 6 and box 1 on facing the wall and meditating, when packing battery into, be contained in the left side or the right regardless of anode, under the effect of draw-in groove 6 and battery folder 2, therefore the neither change of the positive and negative power supply of output has reached the purpose of this utility model.

Claims

1. cathode metal sheet, positive wire and the negative wire that the other end is provided with in a negative spring that is provided with by an end in box, the box, the box constitutes makes things convenient for battery case, it is characterized in that two ends in the box (1) are respectively equipped with to be installed in overlapping with cathode metal shell fragment (3) in the draw-in groove (6) and to load onto insulating case (4) that its front has little " U " v notch v and overlap and load onto that its front has the negative pole metal nest plate (5) of big " U " v notch v and the battery folder (2) made; Between two battery folder (2) of the interior two ends of box (1), wherein symmetrical two cathode metal shell fragments (3) and two negative pole metal nest plates (5), connect with positive wire (7) and negative wire (8) respectively and they are drawn that box (1) is outer to be loaded onto attaching plug or be access to the electrical equipment that uses direct current.
