Detailed Description

The technical solution of the present invention is further explained with reference to the accompanying drawings and specific embodiments.

Example one

As shown in fig. 1-2, the connection assembly with metal elastic sheet provided by the present invention comprises a main housing 1, a cover plate 2 is covered on the top of the main housing 1, a negative electrode column 11 and a positive electrode column 12 are installed on the inner bottom wall of the main housing 1, the height of the positive electrode column 12 is lower than that of the negative electrode column 11, a metal elastic sheet 14 is installed above the negative electrode column 11, a fixing sleeve 3 is fixedly inserted into the cover plate 2, a pressing column 4 is inserted into the fixing sleeve 3 in a sliding manner, a pressing block 5 is fixedly connected to the top of the pressing column 4, a resisting block 6 is fixedly connected to the bottom of the pressing column 4, and the bottom of the resisting block 6 is pressed against the top of the metal elastic sheet 14, when in operation, the pressing block 5 is used to drive the pressing column 4 and the resisting block 6 to descend, the resisting block 6 descends to be pressed against the metal elastic sheet 14 to deform, under the condition, two sides of the metal elastic sheet 14 are pressed against the negative electrode column 11, the middle part of the metal elastic sheet 14 is deformed to abut against the positive electrode column 12, so that the switch is conducted, four symmetrically arranged terminals 16 are installed on the outer wall of the main shell body 1, the terminals 16 are electrically connected with the negative electrode column 11 and the positive electrode column 12, and current is transmitted from the terminals 16; as shown in fig. 1, fig. 3, the rectangle through-hole has all been seted up to main casing body 1's left wall and right wall, fixedly connected with changeover bar 8 in the rectangle through-hole, the peripheral rotation cover of changeover bar 8 is equipped with carousel 9, the outer wall fixedly connected with gag lever post 10 of carousel 9, the fixed cover of outer wall of fixed sleeve 3 is equipped with fixed lantern ring 7, and fixed lantern ring 7 is located the below of gag lever post 10, after rotating carousel 9 certain angle, drive gag lever post 10 and break away from the top of fixed lantern ring 7, just so make pressing post 4, the installation and the dismantlement of apron 2 are very convenient, thereby be convenient for the maintenance of the change of metal shrapnel 14 or internals.
