By providing two anti-reverse insertion members 101, the main control box 1 can be smoothly plugged into the daughter card 100.

[0062] In one embodiment, if Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the display-control separation display terminal structure includes a display unit and a control unit arranged on the display unit. The control unit includes a cover body 8, a main control box 1, a daughter card 100, a baffle assembly 200 and a display component 300. The daughter card 100 is installed on the back of the display unit and is arranged opposite to the main control box 1. The cover body 8 covers the daughter card 100 and the main control box 1. The baffle assembly 200 is installed on the back of the display unit and is located at the daughter card 100. The display component 300 is installed on the cover body 8 and the cover body 8 is exposed.

[0063] When the main control box 1 is plugged into the daughter card 100, the main control box 1 abuts against the baffle assembly 200, and the display element 300 displays the first state. Specifically, the daughter card 100 is installed on the back of the back plate 2 of the display unit, and the baffle assembly 200 is installed on the back of the back plate 2 of the display unit.

[0064] It can be understood that the sub-card 100 of the display-control separation display terminal structure is installed on the back of the display unit and is arranged opposite to the main control box 1. The cover body 8 covers the sub-card 100 and the main control box 1. The baffle assembly 200 is installed on the back of the display unit and is located at the sub-card 100. The display component 300 is installed on the cover body 8 and the cover body 8 is exposed. During the process of plugging the main control box 1 into the sub-card 100, the main control and the baffle assembly 200 are abutted, and the display component 300 displays the first state, so that the main control box 1 and the sub-card 100 are plugged in place without the need for confirmation after power-on, which is convenient and quick.

[0065] It should be noted that when the main control box 1 and daughter card 100 are not properly inserted, the display element 300 displays a second state: the first state can be green, and the second state can be red. Because the main control box 1 abuts the baffle assembly 200 during insertion, the baffle assembly 200's motion signals are transmitted to the display element 300, allowing the display element 300 to display either the first state or the second state. The display element 300 can be powered by a button battery.

[0066] In this embodiment, the baffle assembly 200 includes a baffle 201, a connecting member 202 and a positioning pin 203. The baffle 201 is provided with a accommodating space 2011 and a first through hole 2012 connected to the accommodating space 2011. The connecting member 202 is installed in the accommodating space 2011 and is connected to the positioning pin 203. The positioning pin 203 is exposed from the first through hole 2012 to the outside of the baffle 201. During the process of plugging the main control box 1 into the sub-card 100, the main control box 1 abuts against the positioning pin 203, and the positioning pin 203 drives the connecting member 202 to move in the accommodating space 2011. Specifically, the main control box 1 moves toward the daughter card 100, the main control box 1 abuts against the positioning pin 203, and drives the positioning pin 203 to move along the first through hole 2012, and the positioning pin 203 drives the connecting member 202 to move in the accommodating space 2011. When the main control box 1 and the daughter card 100 are inserted into place, the positioning pin 203 stops moving. At this time, the display member 300 senses the action signal of the connecting member 202, so that the display member 300 displays the first state.

[0067] Furthermore, the baffle assembly 200 includes an elastic member 204, which elastically abuts the connector 202 and the wall of the accommodating space 2011. The elastic member 204 may be a spring. By providing the elastic member 204, when the daughter card 100 is removed from the main control box 1, the elastic deformation force of the elastic member 204 can drive the connector 202 to reset the positioning pin 203.

[0068] Furthermore, the baffle assembly 200 further includes a connecting post 205. The baffle 201 further defines a second through hole 2013 communicating with the accommodating space 2011. The connecting post 205 is connected to the connecting member 202 and disposed in the second through hole 2013. The elastic member 204 extends through the connecting post 205. The provision of the connecting post 205 prevents the elastic member 204 from distorting to one side after elastic deformation occurs, thereby improving the performance of the elastic member 204.
