The vibration fixture of lithium battery plug-in box includes a shaking table 20 of setting on vibration testing machine, and four settings are in on the shaking table 20 and be located respectively lithium battery plug-in box 10's L shape roof 21 all around to and a plane clamp plate 22 of setting on two relative L shape roofs 21 that set up. It is conceivable that the vibration jig is integrally provided on a vibration testing machine, and the vibration testing machine itself is a prior art and will not be described in detail herein.
The vibration table 20 has a planar structure. For the purpose of improving the accuracy of the vibration test, the accuracy of the flatness of the table top of the vibration table 20 should be high, and it is preferable that the flatness of the vibration table 20 is less than 1. In addition, it will be appreciated that the vibration table 20 itself may be a component of the vibration testing machine.
The four L-shaped top plates 21 should be symmetrically arranged so as to be balanced with each other in all directions when vibrated. The four said L-shaped top plates 21 have the same structure and dimensions. Only one of which is described herein. The L-shaped top plate 21 includes a first plate 211 fixedly disposed on the vibration table 20, a second plate 212 fixedly connected to the first plate 211 and abutting against the lithium battery compartment 10, a rib 213 disposed between the first plate 211 and the second plate 212, a plurality of rows of fastener passing grooves 214 disposed on the first plate 211, and a plurality of fasteners 215 respectively passing through the fastener passing grooves 214 and fixed on the vibration table 20.
