Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mobile phone accessories, in particular to a universal card tray assembly. Background Art
[0002] The card tray refers to two card tray openings carved out on a metal sheet, which are divided into the main card slot and the secondary card slot. The main card slot can normally hold a Micro-SIM card, while the secondary card slot can be used to hold a Nano-SIM card or a TF expansion card, allowing users to choose between dual-SIM dual standby and massive storage.
[0003] Nowadays, SIM cards are essential accessories for communication devices. In response to different product requirements, the SIM card holder and card tray structure are also diverse. In recent years, most mobile phone manufacturers have compressed the size of SIM cards to the maximum in order to make mobile phones thinner. The existing mobile phone card tray structure generally has a hole in the card tray cover. Mobile phone manufacturers provide a card ejector pin. When changing the card, insert the card ejector pin into the hole, eject the card tray through the internal structure, and then pull the card tray out by hand to complete the card change.
[0004] At present, the mobile phone industry has higher and higher requirements for the waterproofness of electronic products, especially in the three-proof (waterproof, drop-proof, dustproof) electronic product industry. The waterproofness of the SIM card tray is particularly important, which makes the waterproofing of the increasingly thin card tray very difficult. Most of the three-proof products are waterproofed by adding a rubber plug to the shell structure. This is not only complicated to operate, but also once the rubber plug is opened by mistake, the waterproofing will fail, causing irreversible damage to the electronic product; in addition, the existing card tray and card cap are mostly integrated stamping structures. Different models of mobile phones may need to use different numbers and types of cards, and the card tray cannot be universal, resulting in increased production costs; therefore, a new type of card tray assembly is urgently needed to solve the above problems. Utility Model Content

[0018] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.
[0019] See also Figure 1-2The utility model provides a technical solution: a universal card tray assembly, including a card tray body 1 and a card cap 2 arranged at the end of the card tray body, the card tray body 1 and the card cap 2 are separately arranged, the card tray body 1 is provided with at least one card tray groove 11, the front end of the card tray body 1 is provided with a mounting portion 12, the mounting portion 12 is provided with a round hole 121, the inner side of the card cap 2 is provided with a connecting portion 21, the connecting portion 21 is provided with an annular groove 22, the annular groove 22 is sleeved with a waterproof ring 3, the outer side of the connecting portion 21 is provided with a placement groove 211 connected to the mounting portion 12, and the placement groove 211 is provided with a limiting column 212.
[0020] The universal card tray assembly of the utility model mainly includes a card tray body 1 and a card cap 2. The card tray body 1 and the card cap 2 are separately arranged. The card cap 2 can be matched with various models of card tray bodies 1 for use, and has a wide range of applications, ensuring its versatility. Among them, one, two or three card slots 11 are arranged on the card tray body 1. The number of the card slots 11 is set according to the use requirements of the mobile phone. In addition, the card slot includes a SIM card slot, an SD card slot or a TF card slot, which is suitable for most electronic products. By arranging a mounting portion 12 at the front end of the card tray body 1, a circular hole 121 is arranged on the mounting portion 12 so that it is engaged with a limiting column 212. When the circular hole 121 is stuck in the limiting column 212, it cannot fall out, thereby ensuring the stability of the installation of the card tray body 1; by arranging an annular groove 22 on the connecting portion 21 of the card cap 2 for installing a waterproof ring 3, the waterproof performance of the card tray assembly installed on the electronic product is ensured.
[0021] In a preferred embodiment, referring to Figure 1 and Figure 2 The annular groove 22 of the universal card holder assembly is provided with a plurality of equally spaced card slots 221, and the inner side of the waterproof ring 3 is provided with a card block 31 adapted to the card slot 221. The card block 31 is interference fit with the card slot 221. By providing the card slot 221 in the annular groove 22, the card block on the inner side of the waterproof ring 3 is stuck in the card slot 221, further ensuring the stability of the installation of the waterproof ring 3, which is different from the existing waterproof ring, which is directly sleeved in the annular groove 22 and then glued by glue. During installation and disassembly, it is easy to cause the waterproof ring 3 to loosen, affecting its overall waterproof performance. Therefore, the plurality of card blocks 31 are stuck in the card slot 221 by interference fit, further preventing the waterproof ring from loosening or even falling off, and ensuring a better waterproof effect.
[0022] In a preferred embodiment, referring to Figure 1 and Figure 2The universal card tray assembly has two limit posts 212, which are respectively arranged on the left and right sides of the surface of the placement groove 211. The limit post 212 is mushroom-shaped, with a hemispherical upper end and a cylindrical lower end, and the circular hole 121 is sleeved on the cylindrical limit post. The limit post 212 is used to limit the installation position of the card tray body 1, wherein the limit post 212 is mushroom-shaped, with a hemispherical upper end and a cylindrical lower end, the diameter of the upper end is larger than the diameter of the lower end, and the upper end is made of soft material, which can be deformed when squeezed and quickly recover, such as plastic, silicone, rubber, etc., to facilitate the installation of the circular hole 121 on the card tray body 1, and ensure that the card tray body 1 will not fall out after installation, so that the card cap 2 and the card tray body 1 are connected as a whole.
[0023] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
