Abstract

A clamping device for a universal mobile-phone battery charger comprises a seat, an upper lid, a transparent lid, a spring, two metal electrode pieces, and a plain shaft. The spring is mounted in a spring slot on the transparent lid; the spring slot with the spring mounted therein passes through a T-shaped open slot on the upper lid to cause one end of the spring to rest on the inside the upper lid, and cause the other end to rest against the tail end of the transparent lid; the plain shaft passes through the spring inside the spring slot, and the two ends of the plain shaft are tied in two convex holes opened on the two ends of the front face of the upper lid; the two metal electrode pieces are mounted in an arc-shaped slot on the transparent lid; one end of each of the two metal electrode pieces respectively passes through the T-shaped open slot on the upper lid to connect various electronic components and circuit boards in the seat and can slide sideways in the arc-shaped slot. When the tail fin is pressed slightly, the lower ends of the transparent lid and the upper lid open to allow the mobile-phone battery to be placed therein; the two metal electrode pieces slide in the arc-shaped slot to correspond to the anode and the cathode of the mobile-phone battery; when the tail fin is let go, the upward pre-tightening force of the spring causes the concave blocks arranged in the lower part of the downward surface of the transparent lid to press the mobile-phone battery so as to prevent the battery from sliding or loosening; then the charger is connected to a power source to charge the mobile-phone battery.

Description

The clamping device of universal mobile phone battery charger

Technical field

The utility model relates to a kind of battery charger for mobile phone field, relates in particular to a kind of transparency cover of omnipotent battery charger and upper cover of making and clamps firmly, can save the clamping device of the universal mobile phone battery charger of material ease of assembly again.

Background technology

Along with popularizing of mobile phone, the market demand of charger for mobile phone also significantly increases.Along with the scale of the production of charger for mobile phone, the summary of the material cost of charger for mobile phone and production and assembly technology is also more and more paid attention to by enterprise.Make great efforts to reduce consumptive material, the difficulty that reduces in the production and assembly technical process is enhanced productivity, and has become effective sharp weapon that current phone charger manufacturer participates in market competition.Existing universal mobile phone battery charger, its transparency cover and upper cover generally adopt dual spring to clamp, and the cost that uses dual spring to increase charger has been wasted consumptive material, have also increased the difficulty of assembling simultaneously.

Summary of the invention

The purpose of this utility model is to provide a kind of clamping device that can reduce the universal mobile phone battery charger that consumptive material again can ease of assembly.

For achieving the above object, a kind of clamping device of universal mobile phone battery charger, it comprises a base, a loam cake, a transparency cover, a spring, two metal electrode films, an optical axis.Be provided with two protruding holes at the facial two ends of this loam cake, and on this, cover and be provided with a T type open slot between the two protruding holes.Top is provided with the penetrating spring groove of a caudal peduncle and two ends on this transparency cover, and being provided with one can be provided with one at its downward basifacial and protrude piece for the arc-shaped slit of two metal electrode films slip in its underpart.At first that the utility model universal mobile phone battery charger is required various electronic devices and components and circuit board are put into base and are buckled loam cake, load onto spring in the spring groove on transparency cover, the T type open slot that the spring groove of loading onto spring is passed cover, make a termination of spring be against the inside of loam cake, another termination is against on the caudal peduncle of transparency cover.This optical axis passes the spring that is contained in the spring groove then, and the two ends bolt is in the two protruding holes that the facial two ends of loam cake are offered.Load onto two metal electrode films in the arc-shaped slit on transparency cover, an end of this two metal electrode film passes the T type open slot that covers respectively and connects base interior various electronic devices and components and circuit board, and it can be horizontally slipped in arc-shaped slit.Caudal peduncle on the flicking transparency cover, the lower end of transparency cover and loam cake is opened puts therein battery of mobile phone is anti-, two metal electrode films in the slip arc-shaped slit make its positive and negative two electrodes of corresponding battery of mobile phone respectively, unclamp caudal peduncle because the pretightning force that spring itself makes progress, push down this battery of mobile phone at the protrusion piece that the bottom of its downward one side of transparency cover is provided with, battery can not slided and become flexible, just can give charging mobile phone battery this charger source that Connects Power.
