With the technical solution of the present embodiment, the connector 20 of the LED display device includes: a female connector receptacle 30 and a male connector head 40. The female connector housing 30 includes a first housing 31 and a first plug 32 inserted into the first housing 31. The male connector 40 includes a second housing 41, a second connector 42 movably disposed in the second housing 41, and a rack-and-pinion mechanism 43 capable of driving the second connector 42 to move. The rack and pinion transmission mechanism 43 drives the second connecting portion 42 to move, so that the second connecting portion 42 can be in contact with the first connecting portion 32, so as to electrically connect the female connector socket 30 with the male connector 40. The rack and pinion transmission mechanism 43 includes a first rack portion 431 movably disposed on the second housing 41, a gear portion 434 rotatably disposed on the second housing 41, and a second rack portion 435 disposed on the second patch portion 42.
