Description

A kind of battery occupy-place tube

Technical field

The utility model relates to a kind of occupy-place tube that cooperates ferric phosphate lithium cell to use.

Background technology

The voltage of common alkaline No. 5/No. 7 A batteries is 1.5 volts, and the voltage of No. 5/No. 7 batteries of LiFePO4 is 3.2 volts.Most of electronic products of using battery have all designed and have been fit to 1.5 volts battery chamber on the market.Because ferric phosphate lithium cell has chargeable number of times advantages of higher; Can be on the electronic product that uses even number 1.5 voltaic elements; Replace common alkaline battery with No. 5/No. 7 batteries of LiFePO4, but need to be equipped with the occupy-place tube (being commonly referred to false battery) of same quantity.Though the occupy-place tube does not have battery functi on, but need to realize conducting function, and internal resistance is low more good more.

Now the design of existing occupy-place tube is exactly the empty battery of No. 5/No. 7 batteries that adopt LiFePO4 on the market, realizes electric action through metal battery shell.Though this design can be dealt with problems, also bring some drawbacks.At first, the outward appearance of empty battery and ferric phosphate lithium cell are difficult to distinguish, and the consumer obscures battery and occupy-place tube easily, even the occupy-place tube is put into to charge on the charger causes short circuit.Secondly, the occupy-place tube only is occupy-place and electric action, there is no need fully to realize with empty battery that its cost is too high, is a kind of waste to resource.

The utility model content

The utility model technical problem to be solved provides a kind of occupy-place tube that cooperates ferric phosphate lithium cell use and easy and true battery to distinguish.

The technical scheme that its technical problem of the utility model solution is taked is: this battery occupy-place tube comprises insulation and transparent shell, cathode metal block and negative pole metal nut cap; Said shell is fixed together by two and half shells and the hollow circular cylinder formed, and the inwall of said shell along the circumferential direction is being provided with cannelure respectively near the both ends open place; Said cathode metal block and negative pole metal nut cap place respectively in the cannelure at two ends, and wherein, the noses of said cathode metal block stretch out from the opening part of an end of shell, and the cathode metal block is connected with the negative pole metal nut cap through conductor wire.

Further, the said shell of the utility model is to be linked together through snap fit by two and half shells.

Compared with prior art, the beneficial effect of the utility model is: the shell of (1) existing occupy-place tube is a box hat, is connected the purpose that reaches conduction with box hat through the cathode metal block.And the shell of the utility model battery occupy-place tube adopts the insulation transparent material to make; The consumer can come into plain view to product inside; From distinguishing with battery very intuitively in appearance; Can avoid the occupy-place tube is used as battery charge, thereby solve the problem that original occupy-place tube is prone to and battery is obscured easily, the minimizing accident takes place.Therefore (2) conductive structure of the utility model places the inside of occupy-place tube, and shell is not used further to conduction, be easy to from current material, select, obtain the lower cost materials with transparent nature and prepare shell, and the optional scope of material is big; Simultaneously can guarantee that again the function of occupy-place tube meets or exceeds the like product on the existing market.(3) shell is to be assembled by two and half shells that are fixed together, and can easily conductive structure be installed in the shell thus.(4) battery occupy-place tube be skillfully constructed, simple in structure, mature production technology, simple, production cost reduces than original empty battery occupy-place tube greatly.

The annexation figure of the inner conductive structure of Fig. 2 the utility model battery occupy-place tube;

The decomposing schematic representation of the shell of Fig. 3 the utility model battery occupy-place tube.

Among the figure: 1. cathode metal is blocked a shot; 2. conductor wire; 3. negative pole metal nut cap; 4. shell; 5,7. cannelure; 6,8. buckle.

Embodiment

The utility model is to be made into the shell with the identical size of standard cell by transparent material, and each fixing metal electrode block of two ends middlely connects through a conductor wire.

As shown in Figure 1, the utility model battery occupy-place tube is made up of insulation, transparent shell 4 and inner conductive structure.Wherein, shell 4 is fixed together the hollow circular cylinder of forming (as shown in Figure 3) by two and half shells, and shell 4 is the open at both ends shape.Shell 4 can be selected the transparent plastic preparation of super quality and competitive price for use.The fixed connection mode of two and half shells has multiple, if consider from angle easily, can use buckle-type to fix.The inner conductive structure is linked together through metal conductive wire 2 with negative pole metal nut cap 3 by cathode metal block 1 and forms (as shown in Figure 2).

As shown in Figure 3; The inwall of shell 4 along the circumferential direction is provided with cannelure 5 at the opening part near the upper end; Cannelure 5 is complementary with cathode metal block 1 so that cathode metal block 1 can embed in the cannelure 5 well and the noses of cathode metal block 1 stretch out with suitable with the structure of battery chamber from an end opening of shell 4, and the back side of cathode metal block 1 is the solder side with conductor wire 2.Equally; The inwall of shell 4 along the circumferential direction is provided with cannelure 7 at the opening part near the lower end; Cannelure 7 is complementary so that negative pole metal nut cap 3 can embed in the cannelure 7 well with negative pole metal nut cap 3; Wherein, the front surface of negative pole metal nut cap 3 (convex surface of negative pole metal nut cap 3 as shown in Figure 2) outwardly, the back side then is the solder side with conductor wire 2.For making the occupy-place tube can be suitable with the battery chamber, usually, the end face of the front surface of negative pole metal nut cap 3 and shell 4 or slightly stretch out the end face of shell 4, certain, also can be the front surface that the end face of shell 4 slightly exceeds negative pole metal nut cap 3.

The assembling process of the utility model battery occupy-place tube is following:

At first, weld together, weld together an other end of metal conductive wire 2 and the back side of negative pole metal nut cap 3 then, form the inner conductive structure of battery occupy-place tube thus through the back side and metal conductive wire 2 one ends of welding robot with cathode metal block 1.Then, cathode metal block 1 is put into the cannelure 5 of one of them half shell, and the noses that make cathode metal block 1 stretch out from an end opening of shell 4; Negative pole metal nut cap 3 is put into the cannelure 7 of this half shell, and the front surface that makes negative pole metal nut cap 3 outwardly.At last, two and half shells are fixed together integral body of formation through buckle 6,8, constitute the battery occupy-place tube of the utility model thus.
