Description
Technical Field
The utility model relates to the technical field of connectors, in particular to a terminal with an unlocking structure.
Background
The chinese patent application proposes a terminal, a connector and a connector assembly (bulletin number: CN 217086934U) comprising a terminal body and a locking member fitted over the terminal body, wherein the locking member is used for locking the terminal in a connector housing. An elastic locking piece is formed on the bottom plate and/or the top plate of the locking piece. The spring clip is adapted to engage with a recess on the connector housing to lock the terminal to the connector housing. In general, an unlocking hole communicating with a recess (locking groove) is provided in the connector housing to facilitate insertion of an unlocking tool into the recess through the unlocking hole when the terminal is replaced, thereby unlocking between the terminal and the connector housing.
However, in the state where the elastic lock piece of the terminal is locked to the connector housing, a part of the elastic lock piece is closely attached to the recess (lock groove), and the other part divides a space formed between the recess and the terminal body into two spaces, and the unlocking can be performed only by inserting the unlocking tool into the space between the recess and the elastic lock piece, and the internal condition of the unlocking tool cannot be observed after the unlocking tool is inserted into the unlocking hole, which certainly makes unlocking difficult.
In addition, in order to improve the stability of the terminal in the connector housing, the bending angle of the elastic locking piece is generally designed to be larger, so that the elastic locking piece has better elasticity when being matched with the concave part, and the space between the elastic locking piece and the concave part is smaller than the space between the elastic locking piece and the terminal body. This would certainly make it easier for the unlocking tool to enter the space between the spring lock piece and the terminal body when inserted into the unlocking hole, which would certainly not be possible to unlock.
Therefore, in order to solve the above-mentioned problems, it is necessary to design a terminal having an unlocking structure.
