[0028] This disclosure will now be discussed with reference to several embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and thus implement this disclosure, and are not intended to imply any limitation on the scope of this disclosure.

[0029] As used herein, the term "comprising" and its variations are to be interpreted as open-ended terms meaning "including but not limited to"; the terms "embodiment" and "one embodiment" are to be interpreted as "at least one embodiment"; the term "another embodiment" is to be interpreted as "at least one other embodiment"; the terms "first," "second," etc., may refer to different or the same objects; the term "setup" is not limited to direct or indirect connections, nor to specific connection methods. Other explicit and implicit definitions may also be included below.

[0030] Specific numerical values ​​or ranges may be referred to in the following description. It should be understood that these values ​​and ranges are merely exemplary and may be helpful in putting the ideas of this disclosure into practice. However, the description of these examples is not intended to limit the scope of this disclosure in any way. These values ​​or ranges may be set differently depending on the specific application scenario and requirements.

[0031] As mentioned above, the connectors on existing phone cases cannot be disassembled, replaced, or used to connect other functional accessories, resulting in insufficient flexibility in the use of the phone case. The multi-functional expansion port for phone cases proposed in this utility model at least partially solves the above-mentioned problems. Figures 1-3 As shown, the multi-functional expansion port of the mobile phone case according to this embodiment of the utility model includes a connection port and an expansion component. The mobile phone case includes a housing 100, which is composed of a back panel 01 and a frame 101 surrounding the outer edge of the back panel 01. The frame 101 is formed by a pair of side edges 02, a top edge 03, and a bottom edge 04. The interior of the frame 101 surrounds the back panel 01, and the opposite side of the frame 101 is the exterior. The connection port is used to insert the expansion component, which can be used to connect to a lanyard or other functional accessories.

[0032] The connection port is located on the side 02 of the frame 101. In one embodiment, the number of connection ports can be one, two, or more, and the number of expansion components can also be one, two, or more. When there are two or more connection ports, the same or different expansion components can be inserted into different connection ports, thereby allowing lanyards and other functional accessories to be connected to the phone simultaneously, or allowing lanyards or other functional accessories to be selectively inserted into different connection port positions. For example, as shown... Figure 1 As shown, there are two connection ports: a first connection port 100a and a second connection port 100b. The first connection port 100a is located on the lower left side 02 of the figure, and the second connection port 100b is located on the upper right side 02 of the figure. In this example, the second connection port 100b is used to install the extension component for connecting the lanyard, and the first connection port 100a is idle.

[0033] In one embodiment, the expansion component can also be used to connect other functional accessories. For example, other functional accessories may be a fill light for assisting mobile phone photography. For this purpose, the expansion plug 200 structure of the expansion component is formed to be stably connected with the fill light. That is, the expansion plug 200 structure of the expansion component used to connect different functional accessories may be different.

[0034] The extension component consists of an extension plug 200 and a plug plate 201. The extension plug 200 is connected to one side of the plug plate. For example, the extension plug 200 and the plug plate 201 can be integrally formed. The extension plug 200 is used to connect to a lanyard or other functional accessories. In one embodiment, such as... Figures 1-3 The extension assembly shown for connecting the lanyard has an extension plug 200 formed as a closed ring structure, the inside of which is used to thread the lanyard or a hook component installed on the lanyard.

[0035] The expansion component can be inserted into the connection port from inside the frame 101 of the housing 100, and removed from the connection port through the inside of the frame 101. For example... Figure 1 and Figure 2As shown, the insert plate 201 is installed on the phone case and can be fixedly connected to the connection port by cooperating with it. Specifically, the connection port has a stepped portion 102 on the inner side near the frame 101, and an opening 103 is provided in the central area of ​​the stepped portion 102. The opening 103 passes through the inside and outside of the frame 101, thereby allowing the expansion plug 200 of the expansion component to pass from the inside of the frame 101 to the outside. In the installed state between the expansion component and the connection port, the expansion plug passes through the connection port and protrudes from the outside of the frame 101. The insert plate 201 is placed in the connection port, and the insert plate abuts against the surface of the stepped portion near the inner side of the frame 101, so that the insert plate 201 is flush with the inner side of the side 02, avoiding interference between the insert plate 201 and the phone.

[0036] In one embodiment, the insert plate 201 is shaped as a strip, and the length direction of the strip is consistent with the length direction of the side 02, that is, the strip extends between the top and bottom edges. Accordingly, the size of the insert plate 201 in the strip extension direction is larger than the size of the expansion plug 200 in the same direction, so that if the expansion plug 200 can pass through the opening 103, the insert plate 201 cannot pass through the opening 103 and is blocked by the step portion.

[0037] In one embodiment, such as Figure 4 As shown, the insert plate 201 has symmetrically provided connection holes 201a at both ends of the strip shape. The stepped part 102 of the connection port has protrusions on the surface of the inner side near the frame 101 that can be inserted into the connection hole 201a, thereby ensuring that the expansion component and the connection port are firmly installed.

[0038] In one embodiment, the thickness of the housing 100 is greater than or equal to 3 mm, which can improve the structural strength of the housing 100, especially the structural strength of the connection port, avoid damage to the connection port caused by repeated installation and removal of the expansion components, and ensure the service life of the phone case.

[0039] In one embodiment, the edge of the frame 101 of the housing 100 is bent inward. When the phone and the phone case are installed in place, the inwardly bent edge presses and limits the phone toward the back panel 01 of the housing 100.

[0040] The description of the embodiments herein, including any references to directions and orientations, is for ease of description only and should not be construed as limiting the scope of protection of this utility model. The description of preferred embodiments involves combinations of features, which may exist independently or in combination; this utility model is not particularly limited to the preferred embodiments.
