[0006] Furthermore, the connecting sleeve has a cone structure, and the end of the connecting sleeve away from the display module gradually shrinks.

[0007] Furthermore, a plurality of annular convex strips are provided on the inner side surface of the annular waterproof rubber ring.

[0008] Furthermore, both end surfaces of the annular waterproof rubber ring extend symmetrically from the inner and outer sides of the end surface opening.

[0009] Furthermore, two annular connecting ridges are symmetrically provided on the outer side surface of the annular waterproof rubber ring, and the two connecting ridges are combined to form a clamping groove, and the edge of the end face opening is clamped in the clamping groove.

[0010] Furthermore, the width of the clamping groove is smaller than the thickness of the end surface of the box body.

[0011] Furthermore, the annular waterproof rubber ring is a silicone ring.

[0012] To sum up, the beneficial effects of the present invention are as follows: the present invention provides an end face opening on the box body, and provides a connecting sleeve on the display module, and at the same time clamps an annular waterproof rubber ring with an inner diameter smaller than the outer diameter of the connecting sleeve at the end face opening, so that when the display module is connected to the box body, the connecting sleeve is inserted into the end face opening, which will squeeze the annular waterproof rubber ring at the end face opening, thereby filling the gap between the connecting sleeve and the end face opening, thereby achieving good waterproof effect, simple structure, and convenient installation and connection between the display module and the box body.

[0021] like Figures 1 to 3 As shown, a waterproof connection structure of a display screen connector can effectively improve the waterproof performance of the connector between the display module 2 and the box body 1. It has strong waterproof ability and small size. It not only ensures a stable connection between the connectors, but also facilitates the installation connection between the display module 2 and the box body 1.

[0022] like Figure 1 and Figure 2 As shown, the waterproof connection structure of the display screen connector of this embodiment includes a housing 1 and a display module 2, wherein the housing 1 is provided with a first connection terminal 4, and the display module 2 is provided with a second connection terminal 5. When the display module 2 is connected to the housing 1, the first connection terminal 4 and the second connection terminal 5 mate, thereby achieving an electrical connection between the display module 2 and the housing 1. In this embodiment, an end face opening 11 is opened on the end face of the housing 1, and the first connection terminal 4 is arranged at a position corresponding to the end face opening 11; a connection sleeve 21 is provided on the end face where the display module 2 connects to the housing 1, and the second connection terminal 5 is arranged within the connection sleeve 21. When the display module 2 is connected to the housing 1, the connection sleeve 21 is inserted into the end face opening 11, thereby achieving an electrical connection between the first connection terminal 4 and the second connection terminal 5.

[0023] To improve the waterproof performance when connecting the first connecting terminal 4 and the second connecting terminal 5, this embodiment has an annular waterproof rubber ring 3 clamped onto the end face opening 11. When the display module 2 is connected to the housing 1, the connecting sleeve 21 can be inserted into the inner ring of the waterproof rubber ring, thereby filling the gap between the connecting sleeve 21 and the end face opening 11 through the annular waterproof rubber ring 3, thereby achieving the good waterproof performance of this embodiment. In addition, the inner diameter of the annular waterproof rubber ring 3 of this embodiment is smaller than the outer diameter of the connecting sleeve 21. When the connecting sleeve 21 is inserted into the inner ring of the annular waterproof rubber ring 3, the outer surface of the connecting sleeve 21 can squeeze the annular waterproof rubber ring 3, thereby fully filling the gap, further improving the waterproof performance of this embodiment. The annular waterproof rubber ring 3 can also reversely lock the connecting sleeve 21, thereby improving the connection strength and stability between the display module 2 and the housing 1.

[0024] like Figure 2As shown, the connecting sleeve 21 of this embodiment is a cone structure, and the end of the connecting sleeve 21 away from the display module 2 gradually shrinks, which facilitates the connecting sleeve 21 to be inserted into the annular waterproof rubber ring 3, and as the connecting sleeve 21 is inserted, the outer diameter of the connecting sleeve 21 gradually increases, which will squeeze the annular waterproof rubber ring 3, thereby improving the waterproof performance and connection strength.

[0025] Further, such as Figure 2 and Figure 3 As shown, the inner side surface of the annular waterproof rubber ring 3 of this embodiment is provided with multiple annular ridges 31, so that after the connecting sleeve 21 is inserted into the inner ring of the annular waterproof rubber ring 3, the multiple annular ridges 31 can be sequentially surrounded by the outer side of the connecting sleeve 21, thereby forming multiple waterproof barriers, further improving the waterproof effect of this embodiment; at the same time, the annular ridges 31 can also reduce the inner diameter of the annular waterproof rubber ring 3, thereby further improving the water-repellent ability and connection strength of this embodiment.

[0026] In addition, if Figure 2 As shown, the two side end faces of the annular waterproof rubber ring 3 of this embodiment extend symmetrically from the inner and outer sides of the end face opening 11, so that after the connecting sleeve 21 of this embodiment is fully inserted into the end face opening 11, the annular waterproof rubber ring 3 can not only perform waterproofing at the end face opening 11, but the extended parts of its two side surfaces can also wrap the outer side surface of the connecting sleeve 21 on the inner and outer sides of the end face opening 11 respectively, thereby further improving the waterproof performance of this embodiment, and increasing the contact area between the annular waterproof rubber ring 3 and the outer wall surface of the connecting sleeve 21, thereby improving the plug-in strength of the connecting sleeve 21.

[0027] like Figure 2 and Figure 3 As shown, the outer side surface of the annular waterproof rubber ring 3 of this embodiment is symmetrically provided with two annular connecting ridges 32 on the inner and outer sides of the end face opening 11. The two connecting ridges 32 can be combined to form a snap-fit groove 33, so that the annular waterproof rubber ring 3 can be installed at the end face opening 11 by snapping the edge of the end face opening 11 into the snap-fit groove 33. The installation method is convenient and the connection strength is high.

[0028] Moreover, the width of the snap-fit groove 33 of this embodiment is smaller than the thickness of the end face of the box body 1, so that after the annular waterproof rubber ring 3 is installed, the edge of the end face opening 11 can be embedded in the snap-fit groove 33 and squeezed by the two connecting protrusions 32, thereby improving the installation strength of the annular waterproof rubber ring 3 and preventing the connecting sleeve 21 from being driven off during the plugging and unplugging process.

[0029] The annular waterproof rubber ring 3 of this embodiment is a silicone ring with good deformation ability. After the connecting sleeve 21 is plugged in, it is easy to squeeze it to deform and fill the gap, thereby obtaining good waterproof performance; and it has strong recovery ability, which can ensure the sealing effect and ability after multiple plugging and unplugging and long-term extrusion, and at the same time has a long service life.

[0030] In summary, the working principle of this embodiment is as follows: this embodiment sets an end face opening 11 on the box body 1 and sets a connecting sleeve 21 on the display module 2, and at the same time clamps an annular waterproof rubber ring 3 with an inner diameter smaller than the outer diameter of the connecting sleeve 21 at the end face opening 11, so that when the display module 2 is connected to the box body 1, the connecting sleeve 21 is inserted into the end face opening 11, which will squeeze the annular waterproof rubber ring 3 at the end face opening 11, thereby filling the gap between the connecting sleeve 21 and the end face opening 11, thereby achieving good waterproof effect, simple structure, and convenient installation and connection between the display module 2 and the box body 1.

[0031] The embodiments described above are only preferred implementation methods of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the scope of protection of the present invention.
