Abstract
The utility model provides a power supply terminal protective structure, include the positive terminal and the protection casing that the cover was located on the positive terminal of being connected with the battery positive terminal, be provided with the slot part that supplies the battery positive pole to pass through on the protection casing, make the negative pole can not pass through the slot part that forms to supply anodal passing through on the protection casing for the dry battery is installed conversely and can not be installed, forms the short circuit, has avoided the production after sale.
Description
Technical Field
The utility model relates to a power terminal protective structure and electrical apparatus.
Background
Most of existing household appliances and toys use dry batteries, but the dry batteries are easy to reversely mount due to improper operation of users, so that short circuit of a circuit board is easy to cause after sale.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a power terminal protective structure aims at preventing to lead to the problem of circuit short circuit when the battery dress has been wrong.
The utility model provides a power supply terminal protective structure, include the positive terminal and the protection casing that the cover was located on the positive terminal of being connected with the battery positive terminal, be provided with the slot part that supplies the battery positive pole to pass through on the protection casing, make the negative pole can not pass through the slot part that forms to supply anodal passing through on the protection casing for the dry battery is installed conversely and can not be installed, forms the short circuit, has avoided the production after sale.
In one or more embodiments, the protective cover is disposed on the front side of the positive terminal to form a barrier to prevent installation of the dry cell, and a separator is formed between the negative terminal and the positive terminal of the dry cell to prevent contact between the negative terminal and the positive terminal when the dry cell is reversely installed.
In one or more embodiments, shoulders are arranged on the left side and the right side of the positive terminal, and shoulder parts matched with the shoulders are arranged on the protective cover to form installation.
In one or more embodiments, the left side and the right side of the positive terminal are provided with mounting holes, and the protective cover is provided with inserting blocks matched with the mounting holes so as to be firmly mounted.
In one or more embodiments, the positive terminal is provided with a disk portion protruding forward, and the disk portion is located behind the groove portion.
An electric appliance comprises the power terminal protection structure.
The utility model has the advantages that: the groove part for the positive electrode to pass through is formed on the protective cover, so that the negative electrode cannot pass through, the dry battery cannot be installed in a reversed mode, a short circuit is formed, and the production after sale is avoided.
Drawings
Fig. 1 is a schematic structural diagram of a power terminal protection structure.
Fig. 2 is a schematic diagram of a disassembled structure of the power terminal protection structure.
Detailed Description
