Abstract

The utility model discloses a battery connector, and is composed of an insulating base body and a plurality of conducting terminals; wherein, the insulating base body comprises a bottom plate, and the two sides and the back end of which are extending upwards, forming two side plates and a backwall, and at least, a baffle is arranged between the two side plates and is connected with the bottom plate and the backwall; the space between the two side plates are divided into a plurality of terminal accepting grooves by the baffle, for accepting the equal conducting terminal. The conducting terminal is provided with a welding part, which extends forward from the insulating base body and is welded with the relating printed circuit board, as well as a contact part, which extends upwards from the insulating base body and is in electric connection with the battery. The front end of the insulating base body is provided with a blocking piece, which is arranged at the front side of the contact part, blocking the conducting terminal move forwards. By adopting the structure, when the conducting terminal is over pressed due to the improper setting angle of the battery, the circuit board can be avoided from being contacted due to the over bending of the conducting terminal, and accordingly, the so caused circuit failure or incapability of springing back can be avoided.

Description

Battery connector

Affiliated technical field

The utility model relates to a kind of battery connector, relates in particular to the battery connector that uses in a kind of mobile phone.

Background technology

In traditional battery connector, for example No. 02251929.7 disclosed battery connector of Chinese patent comprises insulating base frame, and the terminal containing slot on the insulating base frame and several correspondences are contained in the conducting terminal of terminal containing slot.

When above-mentioned battery connector is connected use with battery, its conducting terminal contact site drives conducting terminal and produces distortion under the battery extruding, if the battery setting angle is incorrect, make the conducting terminal deflection excessive and cause conducting terminal easily to touch printed circuit board (PCB) easily, cause fault, simultaneously also can terminal be followed the string, even can't rebound because of damage because the terminal deflection is excessive.

The utility model content

The purpose of this utility model is that a kind of battery connector that can avoid fault and conducting terminal to damage is provided at above-mentioned defective.

For achieving the above object, battery connector provided by the utility model comprises: insulating base frame, this insulating base frame comprises a base plate, base plate both sides and rear end extend upward respectively and form biside plate and rear wall, have at least one dividing plate to be placed between the biside plate and with base plate, rear wall and link to each other, dividing plate is divided into the plurality of terminals accepting groove with the cavity between the biside plate; And plurality of conductive terminals, these conducting terminals are contained in the respective terminal accepting groove of insulating base frame, its described conducting terminal has one and stretches out insulating base frame forward and protrude upward insulating base frame with the weld part and of corresponding printed circuit board (PCB) welding and the contact site that electrically connects with battery, it is characterized in that: this insulating base frame front end is equiped with a stopper, but this stopper be positioned at conducting terminal contact site front side backstop its move forward.

As mentioned above, when battery and the assembling of the utility model battery connector, the contact site of battery extruding conducting terminal, contact site moves to stopper, and the extruding stopper, installs up to battery.This has just been avoided the battery setting angle incorrect, battery too extruding can cause the contact site of conducting terminal to move excessive and touch circuit printing plate and causes fault or conducting terminal is followed the string and can't rebound, and makes battery more firm with contacting of conducting terminal by stopper to the reaction force of contact site.
