Description

Cell tester

(1) technical field

The utility model relates to a kind of proving installation of medium and small battery, the concrete cell tester that relates to the medium and small battery of a kind of use in the movable electrical appliances product.

(2) technical background

Cell classification has multiple.Divide from the build size, the large and medium-sized lead-acid accumulator of use on electric automobile, battery-operated motor cycle, Moped Scooter, machine arranged, use is also arranged at small-sized movable electrical appliances, as the compact battery on notebook computer, mobile phone, DVD, the digital camera etc.From whether dividing by charge function, divide one-shot battery such as alkaline zinc-manganese dioxide cell and secondary cell such as cadmium nickel, Ni-H cell, lithium ion battery.Divide from the battery electrode materials used, lithium battery, lithium ion battery, ickel-cadmium cell, Ni-H cell etc. are arranged.Also have other battery such as fuel cell, solar cell etc.Along with economy and development of science and technology, use the portable electronics of battery more and more, as existing notebook computer, mobile phone, DVD, intercom, digital camera, camera, counter, beeper etc.; Requirement to battery is also more and more higher, as require the battery miniaturization, energy density is big, voltage is high, self discharge is few, good cycle, security are good etc.; The model of battery, kind are also very various.Various batteries all will carry out electrical property such as tests such as voltage, strength of current before production is dispatched from the factory or newly purchased the product use or after the secondary cell charge.Now, to test battery various in style, can only seek the cell tester that adapts and test, test multiple different model battery if desired, the battery deck that needs to buy the cell tester of multiple model so or change the battery size that adapts with a kind of cell tester.Buy many cell testers, cost is big, waste of money; Change the battery deck, trouble is lost time.Also there is not a kind of cell tester that can be suitable for measuring variety classes model battery on technique known or the market now.

(3) summary of the invention

The purpose of this utility model is at the defective of prior art and the problem of above-mentioned existence, and a kind of cell tester that need not change the medium and small battery of battery deck energy measurement variety classes, model is provided.Promptly use the utility model, can test the medium and small battery of the wide variety of shapes, specification, monomer or the many bodies that use on the portable electronics.

The technical scheme that realizes the purpose of this utility model is:

A kind of cell tester, form by U font cassette holder etc., respectively there is the slide rail of a toothed bending two sides in cassette holder, respectively there is 5-15 root plastic cement post two sides, on the cassette holder base plate draw-in groove is housed, be equipped with on the draw-in groove, in, lower carriage, be equipped with above the upper bracket can be movable on, in, lower plate, two parallel testing jigs that can move along slide rail are housed between the slide rail of cassette holder two medial surfaces, two ends separately at two testing jigs, be separately installed with a stationary installation, slip-on head that can move left and right is contained on the testing jig, and the bipolarity probe is installed on the slip-on head.The two ends separately of two parallel testing jigs all are contained on the same slide rail, and can upper and lowerly move; Support on the draw-in groove on the cassette holder base plate is made up of the upper, middle and lower-ranking support, and it can freely extract out, put into by the draw-in groove on the base plate; The upper, middle and lower-ranking clamping plate are above upper bracket, and there is the tooth mouth at middle clamp plate and lower plate two ends, in, the tooth mouth of lower plate snaps in the cassette holder two inboard plastic columns that protrude, play fixing in, the lower plate effect, but can upper and lowerly move simultaneously.In, lower plate Si Jiaochu separately has a pilot hole, in, be connected with pillar and spring between lower plate, under its effect, can upper and lowerly move.The stationary installation at testing jig two ends comprises arch font spring, spring base, slip teeth, and arch font spring two is embedded in the spring base; Testing jig all is to be connected by lead with electric connecting mode between the slip-on head, in the testing jig slide bar lead channels is arranged, and the lead on the bipolarity probe of slip-on head is by slide bar, and the passage by cassette holder inside is connected with battery test circuit again.

Design concept of the present utility model is: based on the utility model design philosophy is to test the battery of different volumes size, model, specification with a cell tester as far as possible, make cell tester can test single or double, one or double end electrode contacts.Come from this design philosophy, battery clamp will be moved up and down as far as possible, measuring head wants upper and lower, left and right to move.Specific design is: have in cassette holder upper end two can upper and lower slip testing jig, a slip-on head is all arranged on each testing jig, slip-on head can be on the slide bar of testing jig move left and right, testing jig then slides on the slide rail that has groove of two inside bend about cassette holder, and two ends of each testing jig all have a stationary installation, testing jig can not damage groove when sliding like this.Thereby prolong tester serviceable life.Be battery locating device below testing jig, suitably move up and down the battery clamping plate, can put down the mesuring battary of different model different-thickness.The lead interface channel of cell tester all designs the outside and cannot see any connection lead, thus its outward appearance will cleaner and tidier, attractive in appearance, generous, and operate convenient.Its fancy effect is such: the lead that bipolarity probe on the slip-on head connects by testing jig upper slide bar inside by again by being connected to the battery testing circuit of tester inside in the cassette holder, thereby avoided this easily broken phenomenon of outer lead.The slide rail that has groove of the left and right sides bending of design can make testing jig move up and down on slide rail in the box body, thereby changes the position of testing jig, and each slip-on head above the testing jig can about move around, therefore also can change the position of slip-on head.Like this, no matter the both positive and negative polarity pole piece on the battery is in who position, the position that can correspondingly change two testing jigs and the slip-on head above the testing jig reaches the purpose of test, and each all uses the bipolarity probe above the measuring head, and the data that test out like this are more accurate.

Using method of the present utility model is as follows: be ready to battery to be detected, if thin electroplax, can directly put it in ground floor clamping plate and the second layer clamping plate, if thick electroplax, three supports under the clamping plate can be taken off successively, can begin test to mesuring battary after being positioned in the cell apparatus, at first move up and down two testing jigs and the slip-on head above the mobile test frame, make the both positive and negative polarity pole piece above the bipolarity probe alignment mesuring battary below the slip-on head, be sure of to get final product after the reliable contact.

Good effect of the present utility model: the one, purposes is wide, can measure different volumes, model, specification battery; The 2nd, saved the test duration, avoided frequently more exchange device, battery clamp fork-like farm tool used in ancient China folder test battery; Three are to use conveniently, and measurement data is accurate; The 4th, volume is little, and is easy to carry; The 5th, saved user's investment, using one more.
