Description

Backboard structure and electric connector assembly Technical Field The present disclosure relates to the field of electrical connector assemblies, and in particular, to a back plate structure and an electrical connector assembly. Background In the electrical connector assembly, a back plate structure is one of important structures, and the back plate structure is fixedly arranged on a circuit board for improving the structural strength of the circuit board. A related art, such as CN201252192Y, proposes an electrical connector assembly, which includes an electrical connector assembled above a circuit board and a back plate assembled below the circuit board, wherein a high temperature resistant insulating material with an insulating effect is coated on an upper surface of the back plate to isolate the circuit board from the back plate. The electric connector component has a good insulation effect and is convenient to assemble. However, the backboard of the electric connector assembly needs to be provided with the corresponding avoidance hole according to the position of the capacitor on the circuit board, so that the capacitor on the circuit board can be accommodated in the avoidance hole, the processing and manufacturing difficulty of the backboard is higher, the production difficulty of the electric connector assembly is further greatly improved, meanwhile, the structural strength of the backboard is also greatly reduced, the structural strength of the electric connector assembly is reduced, the circuit board is easy to deform when the electric connector assembly is subjected to the action of a larger external force, and the conductive terminals of the circuit board are unstable in contact with the chip, so that the use stability of the electric connector assembly is greatly reduced. Disclosure of utility model The disclosure aims to overcome the defects in the prior art and provide a back plate structure and an electric connector assembly with lower production difficulty and better use stability.
