Description

Connection structure of battery pole piece and circuit board Technical Field The utility model relates to the technical field of toys, in particular to a connection structure of a battery pole piece and a circuit board. Background The toy remote control, the power-on toy and the like are powered by batteries in most of power supply modes, a battery bin is arranged on a shell of the toy remote control, a battery pole piece is arranged in the battery bin, and the battery pole piece is generally connected with a circuit board inside the shell through a lead. After the battery is arranged in the battery bin, the battery is communicated with the circuit board through the battery pole piece, so that power supply is realized. However, the existing battery pole piece is connected with the circuit board through the lead, so that firstly the lead needs to be welded with the circuit board and the battery pole piece respectively, the operation is troublesome, secondly the lead is easy to break (the lead can be broken in the middle of the lead or at the welding position of the lead) when the product is assembled and disassembled, and consumers often do not have welding conditions, so that the product is invalid, and the user experience is affected. Disclosure of utility model The utility model aims to provide a connecting structure of a battery pole piece and a circuit board, which is convenient and reliable to connect and does not need welding. In order to achieve the above purpose, the utility model discloses a connecting structure of a battery pole piece and a circuit board, which is provided with locking screws corresponding to the battery pole pieces one by one, wherein the locking screws are in threaded connection with the circuit board or a shell provided with the circuit board, the locking screws compress the battery pole piece on the circuit board, and the circuit board is provided with a contact part in conductive connection with the battery pole piece. The circuit board is connected or the shell of the circuit board is connected through the locking screw, so that the battery pole piece is pressed on the contact part of the circuit board, the conductive connection of the battery pole piece and the circuit board is realized, the traditional guide wire welding mode is compared, the battery pole piece and the circuit board are not required to be welded before or during assembly, the locking screw is only required to be locked after the battery pole piece and the circuit board are respectively installed, the operation is more convenient, the assembly station is not required to be provided with welding equipment, and the management is more convenient.
