Description

Battery tray

[technical field]

The utility model relates generally to the battery tray that a kind of self-contained battery is used, respond well, the easy to use and well-set battery tray of especially a kind of battery contact.

[background technology]

No. the 200620072742nd, related prior art such as Chinese patent, its battery tray comprises insulating base frame, positive terminal and negative terminal.When battery is installed, earlier battery one end is placed the lower edge of positive terminal fastener portion, press down the battery other end then, the bullet wall expands outwardly, battery enters accepting groove, makes the conducting strip pressurized strain of negative terminal and contact with the battery floor surface elastic, and the clamping part of positive terminal and the fixture block that plays wall all are fastened in the battery upper surface, so, the battery strong fix is in accepting groove.When taking out battery, outwards pull the bullet wall, make battery break away from projection and fix, elastic conducting strip pops up battery, if pull overexertion when playing wall, plays when wall expands outwardly and will touch retaining wall, then because the restriction of retaining wall, avoid playing wall and surpass its elastic stretch scope and fracture.

Yet battery tray is welded on the circuit board, and its bottom is close to circuit board, outwards pulls the bullet wall and implements relatively effort, is inconvenient to take out battery.

Therefore, be necessary to design a kind of battery tray of improvement to overcome above-mentioned defective.

[utility model content]

The purpose of this utility model is to provide a kind of battery tray that makes things convenient for battery altering.

Be realization the problems referred to above, the battery tray of the utility model, it comprises insulating base frame, positive terminal and negative terminal, this insulating base frame comprises diapire, sidewall and can fix the plastic cement buckle of battery that this plastic card side of detaining is provided with kerve.

Compared with prior art, the plastic card side of detaining of the battery tray of the utility model is provided with kerve, when taking out battery, outwards pull the plastic cement buckle, since kerve make between plastic cement buckle and the circuit board form empty every, outwards move for the plastic cement buckle to provide to allow bit space, then the plastic cement buckle outwards move easily, thereby realize that battery is installed and convenient to remove.
