Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector for a communication device. Background Art

[0002] With the continuous development of society and the continuous improvement of economic level, mobile phones have become an indispensable electronic product in people's daily life. Various SIM cards for different purposes are constantly launched to be paired with mobile phones. Single-mode single-card mobile phones can no longer meet people's multi-purpose needs for mobile phones. In order to solve the problem of frequent card changes for business people who often cross regions or professionals who need to prepare multiple cards, dual-card dual-standby mode mobile phones have appeared on the market.

[0003] There are usually two types of dual-SIM dual-standby mobile phone card sockets in the prior art. The first type is that two single-SIM card sockets are arranged in parallel, such as the Chinese utility model patent with announcement number CN206532909U, which discloses a compatible multi-card connector, including a shell, a card tray, a card ejection mechanism and a connecting terminal. The shell has elastic buckles on both sides, the card ejection mechanism includes a push rod and a swing rod, a rotational connection is formed between the push rod and the swing rod, the push rod is located at a position close to one side of the shell, and the swing rod abuts against the rear end of the shell, the card tray has an SD card accommodating portion, a first SIM card accommodating portion and a second SIM card accommodating portion, the front end of the card tray has a door panel, and both sides of the card tray have claws, the SD card accommodating portion is located closer to the door panel than the first SIM card accommodating portion and the second SIM card accommodating portion, the connecting terminal includes a first connecting terminal group, a second connecting terminal group and a third connecting terminal group, the first connecting terminal group is located in the SD card accommodating portion, the second connecting terminal group is located in the first SIM card accommodating portion, and the third connecting terminal group is located in the second SIM card accommodating portion.

[0004] The second is that two single-card holders are stacked up and down, such as the Chinese utility model patent with announcement number CN201699185U, which discloses a double-layer SIM card connector. The SIM card connector includes a shell, a frame and multiple terminals. The frame includes a mounting plate for embedding multiple terminals. Two spaces for accommodating SIM cards are formed between the shell and the frame. The multiple terminals include a base for embedding the mounting plate and a bending portion for contacting the SIM card, and the multiple terminals bent upward and the multiple terminals bent downward are placed on the mounting plate in a spaced manner. When the two SIM cards are inserted into the connector in the forward or reverse direction, the terminals on the bottom surface of the SIM card on the upper layer contact the multiple terminals bent upward, and the terminals on the top surface of the SIM card on the lower layer contact the multiple terminals bent downward.

[0005] When the above two dual-SIM dual-play mobile phone card holders are in use, the SIM cards will exert a large force on the terminals, which will damage the terminals over a long period of time, resulting in poor contact and a short lifespan.

[0006] Therefore, the prior art needs to be improved and enhanced. Utility Model Content

Specifically, the first pressure-bearing columns 12 correspond to the middle portion of the first support plate 1133 between the first elastic connection end 1131 and the second elastic connection end 1141. The first pressure-bearing column 12 includes a pressure-bearing column body 121 with a groove, a pressure-bearing member 122 disposed above the pressure-bearing column body 121, and a spring 123 disposed between the bottom of the groove and the pressure-bearing member 122.

[0059] As a preferred method of this embodiment, both side walls of the shell 30 are provided with a notch 32 facing the first plastic core 10 or the second plastic core 20 near the left end of the shell 30, and the second plastic core 20 is provided with an anti-reverse protrusion 232 adapted to the notch 32. The fool-proof design formed by the notch 32 and the anti-reverse protrusion 232 limits the insertion direction and insertion depth of the shell 30.

[0060] Specifically, a welding plate 33 is extended outward from each of the four corners of the bottom of the housing 30 for welding the present application to a circuit board.

[0061] As a preferred method of this embodiment, the welding plate 33 is provided with an arc-shaped notch 331, and these arc-shaped notches 331 cooperate with the positioning columns on the circuit board, so that the application is first limited to the accurate position on the circuit board, and then welding is performed, thereby avoiding failure to weld the application to the accurate position on the circuit board and improving the yield rate of the finished product.

[0062] As a preferred mode of this embodiment, a card extraction notch 34 is provided at one end of the housing 30, so that the user can use an external tool to eject the user identification card from the present application in certain usage scenarios.

[0063] In summary, the present invention solves the deficiencies in the prior art through the above-mentioned structural design, and has the characteristics of reasonable structure, long service life, strong practicality, etc.
