The operation is time-saving and labor-saving, and the production and maintenance efficiency is improved.

The following embodiments mainly take the scheme that the rear side plate 22 is provided with the jack 4, and the front side plate 12 is provided with the elastic plug connector 3 at the position corresponding to the jack 4 as an example to describe the specific structure and details; the structure and details of the solution in which the front plate 12 is provided with the insertion holes 4 and the rear plate 22 is provided with the resilient insertion members 3 at positions corresponding to the insertion holes 4 can be similarly considered.

Specifically, the structure of the flexible plug 3 is as shown in fig. 6 and 9, and includes a bracket 41, a spring 42 and a plug 43, wherein one end of the spring 42 is connected to the bracket 41, and the other end is connected to the plug 43. The difficulty of directly fixing the spring 42 on the plane of the front side plate 12 is high, and the stability and the reliability after assembly are not high; and the spring 42 is the main moving part in the course of disassembling and assembling, if the spring 42 is connected with the level of the front side plate 12 directly, once the spring 42 appears fatigue state and needs to be changed, then need to deal with the front side plate 12 correspondingly, namely dismantle the fatigue spring 42 from the front side plate 12 first, fix the spring 42 with good use state on, it is very troublesome for the maintenance of the later stage; therefore, the bracket 41 is firstly arranged on the front side plate 12, one end of the spring 42 is connected with the bracket 41, the other end of the spring 42 is connected with the plug connector 43, the connection between the front side plate 12 and the spring 42 is transited through the bracket 41, the bracket 41 can be adjusted to be suitable for the shape of the assembled spring 42 according to requirements, and in this way, the spring 42 and the plug connector 43 can be assembled on the front side plate 12 more firmly.

The insertion hole 4 is disposed on the rear side plate 22, specifically referring to fig. 3, the bracket 41 is connected to the inner side of the front side plate 12, a gap 13 is formed between the bracket 41 and the front side plate 12, the rear side plate 22 is located in the gap, and the plug connector 43 is inserted into the insertion hole 4 of the rear side plate 22. The rear side plate 22 is located in the gap 13, and functions as two, one: the bracket 41 and the front side plate 12 both limit the rear side plate 22, so that the connection between the front side plate 12 and the rear side plate 22 is more stable; the second step is as follows: the elastic plug connector 3 and the jack 4 after the assembly is finished cannot be exposed, namely, the assembly parts cannot be seen from the outside of the product, so that the appearance consistency of the product is improved.

In order to convert the pressing force applied to the connector 43 into a direction, a guide end surface 431 may be provided on the connector 43, and as shown in fig. 4, when the rear side plate 22 is inserted into the gap in the thickness direction of the display device and presses the guide end surface 431, the guide end surface 431 may convert the pressing force in the thickness direction X of the display device into a pressing force in the expansion and contraction direction Y of the spring 42. In this process, when the rear plate 22 is inserted into the gap 13 between the bracket 41 and the front plate 12, the rear plate contacts the plug 43, so as to generate an X-directional pressing force on the plug 43, and the direction of the pressing force is not consistent with the extending and retracting direction of the spring 42, but the direction of the pressing force changes under the guidance of the guide end surface 431 and is converted into a pressing force along the extending and retracting direction Y of the spring 42, so that the plug 43 is retracted into the bracket 41, and the rear plate 22 can smoothly enter the gap 13 to reach the position of the jack 4.

The whole inserting process specifically comprises the following steps: before plugging, referring to fig. 4, the plug 43 is located in the gap between the bracket 41 and the front side plate 12. When the rear plate 22 is inserted into the gap in the thickness direction of the display device, the rear plate 22 contacts the guide end face 431 of the plug 43 and presses the guide end face 431, and at this time, the guide end face 431 converts the pressing force in the thickness direction of the display device into the pressing force in the expansion and contraction direction of the spring 42, so that the plug 43 is retracted by the pressing force converted by the guide end face 431, and the rear plate 22 is allowed to be inserted into the gap continuously until the position of the jack 4 on the rear plate 22 is opposite to the position of the plug 43, referring to fig. 3, the plug 43 is extended and inserted into the jack 4 by the restoring force of the spring 42. The position of the rear side plate 22 is limited by the plug 43 and the jack 4, and the front case 1 and the rear case 2 are assembled. It can be seen that the guide end surface 431 functions to convert the direction of the pressing force so that the plug 43 can be retracted, and the rear side plate 22 can be smoothly inserted into the gap 13 at the position of the insertion hole 4.

Therefore, the guide end surface 431 is preferably a slope, a cambered surface, a spherical surface, or the like, and as shown in fig. 4 and 5, the guide end surface 431 can convert the received pressing force into a pressing force along the expansion and contraction direction of the spring 42.
