Background technology

Present universal charger two electrode tail ends directly are fixed on the clamp by one piece of screw, during use according to the interval of the conductive contact of battery, just adjust, negative two interelectrode intervals, each electrode is when adjusting, can only be that the round dot rotation is adjusted with the screw of tail end, two electrodes are in contact with one another in rotary course and short circuit phenomenon occurs in the rotary course, be located at respectively in the two strip electrode chutes at two electrodes, two electrodes can only slide in chute separately, that is to say a chute is isolated into two chutes, if the electrode on the clamp left side can only move at the sector region on the left side of clamp, if the electrode on clamp the right can only move at the sector region on the right of clamp, and be located near the summit wherein battery for some conductive contacts, in charging process, after both positive and negative polarity conductive contact on the battery has been aimed in two electrode adjustment, clamp can only clip to a battery part seldom, battery is loosening easily, causes loose contact, even battery occurs and come off and break battery.

Summary of the invention

In sum, main purpose of the present utility model is to solve existing universal charger in use, the problem of clamping stability test difference, and a kind of universal charger that proposes.

For realizing that the technical scheme that the purpose of this utility model adopts is: a kind of universal charger, comprise: charger body, clamp and positive and negative electrode, it is characterized in that: also comprise two electrode fixed blocks, described clamp is provided with two parallel electrodes fixed block chutes and electrode chute; Described electrode fixed block is provided with the raised step that the well width with electrode fixed block chute matches, the electrode fixed block is located on the clamp medial surface, the raised step of electrode fixed block is located in the fixed block chute, and the tail end of positive and negative electrode is connected with an electrode fixed block by screw on the lateral surface of clamp respectively; The front end of positive and negative electrode is spent bendings after the electrode chute is located between clamp and the charger body through 90.

Described positive and negative electrode tail end passes through two pieces of screw fixings respectively on an electrode fixed block.

Described positive and negative electrode front end conductive contact is the longitudinal metal chip architecture of vertical charger body.

Described positive and negative electrode is respectively equipped with insulation shell outward.

Also be provided with rubber blanket between described electrode fixed block and clamp.

The beneficial effects of the utility model are: positive and negative two of the present utility model are separately fixed on the electrode fixed block, two electrode fixed blocks can be free to slide at left and right two ends in the fixed block chute by the step of a projection, no matter where the positive and negative electrode conductive contact of battery is located at, clamp can firmly be clamped in the center of battery, the outer insulation shell of positive and negative electrode is avoided the direct contact electrode of human body, also can not injure human body when electric leakage occurring.

Embodiment

Below in conjunction with accompanying drawing and preferred embodiment structure of the present utility model is further described:

Shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the utility model comprises housing 1, clamp 2, left electrode 31, right electrode 32, left electrode fixed block 41 and right electrode fixed block 42.Clamp 2 is connected with housing 1 by axle and spring, except being provided with electrode chute 21, also has a strip electrode fixed block chute 22 on the clamp 2, and electrode chute 21 is two parallel bar shaped chutes with electrode fixed block chute 22.Left side electrode 31 ordinary circumstance positive electrodes; Right electrode 32 is a negative electrode, also can set up switching key on housing 1 as required, switches two electrode attributes.The front end conductive contact of two electrodes of present universal charger is that the direct bending of metal clips is formed, conductive contact is a slice sheet metal parallel with cell plane, and the conductive contact of some batteries is the elastic opening shape, conductive contact 311,321 of the present utility model is a slice sheet metal vertical with cell plane, can avoid that some elastic opening shape conductive contacts is big by 311,321 of conductive contacts in use, cause and the mobile phone loose contact.The medial surface of clamp 2 is provided with two electrode fixed blocks 41,42, electrode fixed block 41,42 are provided with a square raised step 411,421, square raised step 411, the well width of 421 width and fixed block chute 22 matches, electrode fixed block 41, square raised step 411 on 42,421 parts are located in the fixed block chute 22, limit electrode fixed block 41,42 can only horizontally slip in fixed block chute 22, can not produce rotation, and at electrode fixed block 41,42 and 2 of clamps also be provided with rubber blanket 412,422, adjusting electrode fixed block 41, behind 42 the position, can be from line slip, when having only external force to pull out, just can in fixed block chute 22, move.The tail end of left side electrode 31 and right electrode 32 is fixedlyed connected with fixed block 41,42 by two pieces of screws 312,322 from the upper surface of clamp 2 respectively, the charging output of charger body 1 is connected with two electrodes 31,32 by lead, and the front end of left electrode 31 and right electrode 32 is spent bendings after electrode chute 21 is located between clamp 2 and the charger body 1 through 90.In order to prevent that electric leakage from appearring in charger body 1 internal circuit, finger touched the generation that shock hazard appears in two electrodes 31,32 when the user regulated, on two electrodes, 31,32 tail ends, also be respectively equipped with an insulation shell 313,323, insulation shell 313,323 can be directly to be connected on two electrodes 31,32, also can be fixing by screw 312,322, when using screw 312,322 fixedly, the screw hole 3131,3231 of insulation shell 313,323 has the lower edge that cooperates with screw hole on the electrode, avoids conducting electricity between screw 312,322 and electrode.
