The fixing body 131 includes a main body 1311 and a bent part 1312 formed by bending the end of the main body 1311. The bent part 1312 overlaps with the edge of the display module 11, as shown in FIG. 1 , specifically It can be overlapped on the protrusion 1111 on the edge of the cover glass 111. Of course, if the above-mentioned protrusion is not provided on the edge of the cover glass, the above-mentioned bending part can also be directly overlapped on the upper edge of the cover glass.

The above-mentioned main body part 1311 is in the shape of a belt, and its ends are connected and closed, and tightly surrounds the display module 11, specifically, it may surround the protrusion 1111 on the edge of the cover glass 111, that is, the main body The size surrounded by the portion 1311 is equal to the outline size of the cover glass 111 . At this time, the bent portion 1312 faces toward the center of the display module 11 .

The above-mentioned sealing body 132 can be fixed on the top of the bending part 1312, and the sealing body 132 is blocked in the gap between the housing 12 and the display module 11 to play a role of sealing. See Figure 1 for details. .

The material of the above-mentioned fixing body 131 can be stainless steel, and the material of the sealing body 132 can be silica gel, and the fixing body 131 and the sealing body 132 are integrally formed by injection molding, and the sealing body 132 made of silica gel is fixed on the bend of the fixing body 131. The top of portion 1312.

It can be seen from FIG. 1 and FIG. 3 that the main body 1311 of the connector 13 is provided with a locking hole 1313, and at the same time, on the side wall of the shell body 121, there is also a hole corresponding to the position of the locking hole 1313. The clamping member 124 , referred to here as a side wall, refers to a side of the casing 12 parallel to the fixing body 131 in FIG. 1 .

Specifically, the clamping member 124 may include an embedded portion 1241 and a clamping portion 1242 , the embedded portion 1241 is embedded in the side wall of the housing body 121 , and securely fixes the entire clamping member 124 on the side wall of the housing 12 . The clamping part 1242 protrudes from the side wall of the shell body 121. It can be seen from FIG. The side walls of the housing 12 overlap; the upper bottom of the engaging portion 1242 is parallel to the side wall of the housing 12; the waistline of the hypotenuse of the engaging portion 1242 is adjacent to the bending portion 1312; The waistline of the right-angle side of the engaging portion 124 is away from the bending portion 1312 .

The embodiment of the present application provides the above-mentioned mobile terminal 100. Through the provided connector, the connector includes a fixed body and a sealing body. When assembling the display module and the housing, compared with the complicated glue dispensing process in the prior art, the assembly and fixation of the display module and the housing can be quickly realized.

In addition, in the connector, a sealing body is fixed on the top of the bending part, and the sealing body is sealed in the gap between the housing and the display module, so as to realize the sealed connection between the housing and the display module. , to meet the sealing requirements between the housing and the display module.

For the "quick" assembly mentioned above, it is mainly reflected in: Compared with the prior art, this application only needs to set protrusions on the edge of the cover glass, and at the same time set a snap-fitting part on the housing and process the connecting parts. All operations can be completed before assembly. In this way, when assembling the display module and the housing, it is only necessary to use the assembly jig, first place the display module in the housing, and then connect the connectors from top to bottom. Next, it is inserted into the gap between the display module and the casing, and the assembly of the display module and the casing can be completed.

It should be noted that, in this embodiment, the main body portion 1311 of the connector 13 is in the shape of a belt, and the ends are connected and closed, and tightly surround the display module 11. Of course, in other embodiments, The connecting piece can also be designed in sections and surround the display screen module 11 , as long as it can achieve the effect of fixing the display screen module 11 in the casing 12 .

In addition, in this embodiment, the cross-section of the clamping portion 1242 is a right-angled trapezoid, the lower base of which coincides with the side wall of the housing 12; the upper base is parallel to the side wall of the housing 12; the waistline of the hypotenuse Adjacent to the bent portion 1312 ; the waistline of the right-angled side is away from the bent portion 1312 . At this time, the outline of the locking hole 1313 on the main body 1311 may be a rectangle. When assembling the display module and the housing, the assembly fixture is used to first place the display module in the housing, and then insert the connector between the display module and the housing from top to bottom When it is in the gap, the locking hole 1313 on the main body 1311 and the locking portion 1242 can be automatically and firmly locked without other operations, thereby further improving the assembly efficiency.

In this embodiment, since the material of the fixing body 131 can be stainless steel, the overall fixing body 131 can be made thinner, and the sealing body 132 made of silica gel can be sealed between the display module 11 and the housing 12, even if If the mobile terminal 100 falls, the sealing body can provide cushioning and reduce the risk of damage to the display module. In addition, the fixing body 131 is relatively thin, so there is still a gap between the display module 11 and the casing 12. When the mobile terminal 100 falls, compared with the mobile terminal in the prior art that completely seals the gap with glue, the above gap can It further plays a buffering role and further reduces the risk of damaging the display screen module.

In this embodiment, the sealing body made of silica gel is arranged on the top of the bending part, and the height (or thickness) of the sealing body can be adjusted to solve the gap between the housing and the display module in the prior art. In this way, the mobile terminal including the mobile terminal 100 can improve user experience.
