Abstract

This utility model relates to a NANO SIM card holder connector in the field of connector technology. It includes a male connector metal shell, a plastic body, and a metal terminal assembly. One end of the first, second, third, and fourth connecting terminals are all bent and independently configured. A metal pull rod is installed inside the plastic body, and a metal rotating shaft is connected to the surface of the plastic body for mating with the metal pull rod.

Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a NANO SIM card socket connector. Background Technology

[0002] The NANO SIM card socket connector is a miniature electronic interface device specifically designed for securing, connecting, and enabling electrical communication of NANO SIM cards in miniaturized electronic products such as smartphones, tablets, smartwatches, and IoT devices.

[0003] Most existing NANO SIM cards are removed by using a SIM card ejector tool. When the tool is unavailable, a toothpick or small needle-like object is needed to press into the SIM card slot to eject the card. However, this process may cause the toothpick or needle-like object to break off and become lodged inside the slot, causing blockage and making subsequent installation inconvenient. To address this issue, the inventors have proposed a NANO SIM card slot connector to solve the aforementioned technical problem of improving the traditional SIM card ejector tool method. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0005] A NANO SIM card socket connector includes a male socket metal housing, a plastic body, and a metal terminal assembly. The metal terminal assembly includes a first connecting terminal, a second connecting terminal, a third connecting terminal, and a fourth connecting terminal. One end of each of the first, second, third, and fourth connecting terminals is a bent structure and is independently arranged. The surface of the plastic body has an installation groove for assisting in the installation of the metal terminal assembly. A metal pull rod is installed inside the plastic body. A metal pivot for mating with the metal pull rod is connected to the surface of the plastic body. The metal pivot is movably mounted on the surface of the plastic body. This structure uses a metal pull rod and a metal pivot to automatically eject the SIM card. When the user presses the end of the metal pull rod that extends beyond the housing, it pushes the metal pull rod inside the card tray. The metal pull rod moves inside the plastic body and forms a lever or rotational connection with the card tray or related linkage mechanism through the metal pivot. The linear motion of the pull rod is converted into the rotation or translational motion of the card tray through the pivot, thereby pushing the SIM card out of the card slot for easy removal by the user and greatly improving the convenience of use. In addition, four terminal structures—the first, second, third, and fourth connecting terminals—are added, employing independent bending structures to provide a stable, low-impedance electrical connection. When the SIM card is inserted into the connector, the surface of the SIM card applies a certain pressure to the bending structure. Due to the reaction force generated by the bending action of the bending structure, the connection stability between the terminal and the metal contacts of the SIM card is increased, reducing the probability of detachment or poor contact. The metal shaft focuses on mechanical transmission, and the two are functionally separated to avoid interference of mechanical movement with electrical signal transmission, ensuring the stability and reliability of SIM card data communication. On the other hand, the overall shape of the first connecting terminal, the second connecting terminal, the third connecting terminal and the fourth connecting terminal is L-shaped. This shape is conducive to the conduction of current and reduces the blockage of electrical signals. The two protrusions added to the two ends of the terminal effectively provide good installation stability and prevent the terminal from falling off.

[0006] Furthermore, one end of the hardware rod is wrench-shaped, and the other end of the hardware rod is L-shaped. The wrench-shaped end of the hardware rod is fastened to the hardware shaft, and the other end of the hardware rod extends beyond the surface of the plastic body. The "wrench-shaped" structure has a groove or bayonet-like structure that forms a snap-fit ​​connection with the metal shaft. This effectively prevents the pull rod from detaching from the shaft, slipping, or rotating out of position during movement. When the jack pushes the pull rod, the force is firmly transmitted to the shaft through the "wrench" structure, making it a fulcrum to drive the linked jack mechanism to rotate or translate. This achieves a highly efficient lever amplification effect, ensuring smooth assembly and reliable operation even when there are slight dimensional deviations between the plastic body and the metal parts, thus improving production yield. The other end of the metal pull rod has an "L" structure, which provides an effective force input point and motion guidance. The end of the "L" structure, as the force-bearing end, is directly exposed on the push path of the card holder or in contact with the push pin on the card holder. Its "L"-shaped geometry better absorbs the thrust from the card ejector pin or card holder, preventing force deviation or slippage. Furthermore, one end can slide within a specific guide groove in the plastic body, ensuring that the pull rod moves only in a predetermined straight line, avoiding skewness or jamming, and serving as a guide and limiter.

[0007] Furthermore, one end of each of the first, second, third, and fourth connecting terminals extends beyond the surface of the plastic body, with their height and length aligned. This alignment ensures stable contact with the SIM card. This structure provides a uniform electrical connection to the SIM card. When the SIM card is inserted into the card slot, its surface metal contacts contact the connector terminals. Because all terminals have the same internal structure and elastic design, and the external soldered ends are aligned, this ensures that the initial position and elasticity of the internal contact terminals are consistent. This allows each contact of the SIM card to receive balanced contact pressure, preventing signal interruption, data reading failure, or the device's inability to recognize the SIM card due to poor contact at a single terminal. The uniform contact pressure ensures a stable physical connection between metals, effectively reducing contact resistance and ensuring stable transmission of data, such as communication signals and power.

[0008] Furthermore, the surface of the male connector hardware shell is provided with a clearance groove that avoids the bending structure at one end of the hardware terminal assembly. The clearance groove penetrates the surface of the male connector hardware shell. Both ends of the male connector hardware shell are provided with a retaining plate to increase connection stability. The surface of the retaining plate is provided with a raised structure. The clearance groove provides space for the bending structure of the internal metal terminals to avoid physical interference and damage. When the plastic body is pressed into or assembled into the male connector metal housing, if there is no reserved space, the bent terminal part will directly hit the inner wall of the metal housing, which may cause the terminal to deform and affect the function. The locking plate with the raised structure increases the stability of the connection. The raised structure increases the contact points and increases the locking force, preventing the terminal from falling off during use.

[0009] Furthermore, a conductor is installed inside the plastic body, and a slot is formed on the surface of the plastic body to place the conductor. The conductor can be used as an independent power signal to connect to the card tray detection switch to realize the control logic. The slot is used to limit the position of the conductor and prevent the conductor from moving. This limiting method can maintain a stable connection even under equipment vibration or thermal expansion and contraction, and avoid functional failure due to conductor loosening.

[0010] Furthermore, the surface of the male seat hardware shell is respectively provided with a pull rod spring plate for limiting the movement of the hardware pull rod and a limiting spring plate for increasing the connection stability between the male seat hardware shell and the external connecting groove. The pull rod spring plate provides elastic force, and its installation position and shape also physically limit the movement stroke of the hardware pull rod, preventing the pull rod from extending or retracting excessively, and avoiding structural damage or functional failure caused by excessive movement. When the pull rod spring plate applies a certain preload to the hardware pull rod, it is in a stable position when stationary, eliminating the effect of mechanical backlash and ensuring that the action response of the push-lock action can be carried out effectively. The limiting spring plate, when the male seat hardware shell is connected to the corresponding groove, uses its own elastic effect to generate outward tension on the surface of one end of the male seat hardware shell in the groove, increasing the connection stability between the male seat hardware shell and the groove.

[0011] Furthermore, the surface of the plastic body is provided with a pivot point that is matched and installed with the metal shaft. One end of the plastic body is provided with a stop to prevent the metal shaft from overtravel. When the metal shaft rotates, it moves around the pivot point as the center. The stop limits the range of movement of the metal shaft to avoid misalignment when the SIM card is ejected or installed due to excessive range of movement.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the SIM card is automatically ejected by the cooperation of the metal pull rod and the metal rotating shaft. When the user presses the end of the metal pull rod that extends beyond the shell, it will push the metal pull rod inside the card tray. The metal pull rod moves inside the plastic body and forms a lever or rotational connection with the card tray or related linkage mechanism through the metal rotating shaft. The linear motion of the pull rod is converted into the rotation or translational motion of the card tray through the rotating shaft, thereby pushing the SIM card out of the card slot, making it convenient for the user to take out and greatly improving the convenience of use. In addition, four terminal structures—the first, second, third, and fourth connection terminals—are added, employing independent bending structures to provide a stable, low-impedance electrical connection. Furthermore, the reaction force of the bending structure increases the connection stability between the terminals and the SIM card's metal contacts, reducing the probability of detachment or poor contact, thus ensuring the stability and reliability of SIM card data communication.

Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] For this embodiment, please refer to Figures 1-8 The present invention relates to a NANO SIM card socket connector, comprising a male socket metal housing 1, a plastic body 2, and a metal terminal assembly. The metal terminal assembly includes a first connecting terminal 3, a second connecting terminal 4, a third connecting terminal 5, and a fourth connecting terminal 6. One end of each of the first connecting terminal 3, the second connecting terminal 4, the third connecting terminal 5, and the fourth connecting terminal 6 is a bent structure and is independently set. The surface of the plastic body 2 is provided with a mounting groove 7 for assisting in the installation of the metal terminal assembly. A metal pull rod 8 is installed inside the plastic body 2. A metal pivot 9 for mating with the metal pull rod 8 is connected to the surface of the plastic body 2. The metal pivot 9 is movably mounted on the surface of the plastic body 2. This structure uses a metal pull rod 8 and a metal rotating shaft 9 to automatically eject the SIM card. When the user presses the end of the metal pull rod 8 that extends beyond the housing, it pushes the metal pull rod 8 inside the card tray. The metal pull rod 8 moves inside the plastic body 2 and forms a lever or rotational connection with the card tray or related linkage mechanism through the metal rotating shaft 9. The linear motion of the pull rod is converted into the rotation or translational motion of the card tray through the rotating shaft, thereby pushing the SIM card out of the card slot for easy removal by the user and greatly improving the convenience of use. In addition, four terminal structures—first connection terminal 3, second connection terminal 4, third connection terminal 5, and fourth connection terminal 6—are added. These structures employ independent bending structures to provide a stable, low-impedance electrical connection. When the SIM card is inserted into the connector, the surface of the SIM card applies a certain pressure to the bending structure. Due to the reaction force generated by the bending action of the bending structure, the connection stability between the terminal and the metal contacts of the SIM card is increased, reducing the probability of detachment or poor contact. The metal shaft 9 focuses on mechanical transmission. The two are functionally separated, avoiding interference of mechanical movement with electrical signal transmission and ensuring the stability and reliability of SIM card data communication. On the other hand, the overall shape of the first connecting terminal 3, the second connecting terminal 4, the third connecting terminal 5 and the fourth connecting terminal 6 is L-shaped. This shape is conducive to the conduction of current and reduces the blockage of electrical signals. The two protrusions added to the two ends of the terminal effectively provide good installation stability and prevent the terminal from falling off.

[0016] One end of the hardware pull rod 8 is wrench-shaped, and the other end of the hardware pull rod 8 is L-shaped. The wrench-shaped end of the hardware pull rod 8 is fastened to the hardware pivot 9, and the other end of the hardware pull rod 8 extends beyond the surface of the plastic body 2. The "wrench shape" is a groove or bayonet structure. This structure forms a snap-fit ​​connection with the metal shaft 9, effectively preventing the pull rod from disengaging, slipping, or rotating out of position during movement. When the jack pushes the pull rod, the force is firmly transmitted to the shaft 9 through the "wrench" structure, making it a fulcrum to drive the linked jack mechanism to rotate or translate, achieving a highly efficient lever amplification effect. Even when there are slight dimensional deviations between the plastic body 2 and the metal parts, smooth assembly and reliable operation can be guaranteed, improving production yield. The other end of the metal pull rod 8 has an "L" structure, which provides an effective force input point and motion guidance. The end of the "L" structure, as the force-bearing end, is directly exposed on the pushing path of the card tray or in contact with the push pin on the card tray. Its "L"-shaped geometry can better bear the pushing force from the card ejector pin or card tray, preventing force deviation or slippage. Furthermore, one end can slide within a specific guide groove in the plastic body 2, ensuring that the pull rod moves only in a predetermined straight direction, avoiding skewness or jamming, and serving as a guide and limiter.

[0017] One end of each of the first connecting terminal 3, the second connecting terminal 4, the third connecting terminal 5, and the fourth connecting terminal 6 extends beyond the surface of the plastic body 2, and their height and length are flush. This flush height and length ensures stable contact with the SIM card. This structure provides a uniform electrical connection to the SIM card. When the SIM card is inserted into the card slot, its surface metal contacts contact the connector terminals. Because all terminals have the same internal structure and elastic design, and the external soldered ends are flush, this ensures that the initial position and elasticity of the internal contact terminals are consistent. This allows each contact of the SIM card to receive balanced contact pressure, preventing signal interruption, data reading failure, or the device's inability to recognize the SIM card due to poor contact at a single terminal. The uniform contact pressure ensures a stable physical connection between metals, effectively reducing contact resistance and guaranteeing stable transmission of data, such as communication signals and power.

[0018] The surface of the male seat hardware shell 1 is provided with a clearance groove 10 that avoids the bending structure at one end of the hardware terminal assembly. The clearance groove 10 penetrates the surface of the male seat hardware shell 1. Both sides of the male seat hardware shell 1 are provided with a retaining plate 11 to increase connection stability. The surface of the retaining plate 11 is provided with a protruding structure. The clearance groove 10 provides space for the bending structure of the internal hardware terminals to avoid physical interference and damage. When the plastic body 2 is pressed into or assembled into the male hardware housing 1, if there is no reserved space, the bent terminal part will directly hit the inner wall of the metal housing, which may cause the terminal to deform and affect the function. The latching plate 11 with the protruding structure increases the connection stability. The protruding structure increases the contact points and increases the latching force, preventing the terminal from falling off during use.

[0019] The plastic body 2 has a conductor 12 installed inside. The surface of the plastic body 2 has a slot 13 for placing the conductor 12. The conductor 12 can be used as an independent power signal to connect to the card tray detection switch to realize the control logic. The slot 13 is used to limit the position of the conductor 12 and prevent the conductor 12 from moving. This limiting method can maintain a stable connection even under equipment vibration or thermal expansion and contraction, and avoid functional failure due to loose conductor 12.

[0020] The surface of the male seat hardware shell 1 is respectively provided with a pull rod spring plate 14 for limiting the movement of the hardware pull rod 8 and a limiting spring plate 15 for increasing the connection stability between the male seat hardware shell 1 and the external connecting groove. The pull rod spring plate 14 provides elastic force, and its installation position and shape also physically limit the movement stroke of the hardware pull rod 8, preventing the pull rod from extending or retracting excessively, and avoiding structural damage or functional failure caused by excessive movement. When the pull rod spring plate 14 applies a certain preload to the hardware pull rod 8, it is in a stable position when stationary, eliminating the effect of mechanical backlash and ensuring that the action response of the push-lock action can be carried out effectively. The limiting spring plate 15, when the male seat hardware shell 1 is connected to the corresponding groove, through the elastic effect of the limiting spring plate 15 itself, causes the surface of one end of the male seat hardware shell 1 to generate external tension in the groove, increasing the connection stability between the male seat hardware shell 1 and the groove.

[0021] The surface of the plastic body 2 is provided with a pivot point 16 that is matched and installed with the metal shaft 9. One end of the plastic body 2 is provided with a stop block 17 to prevent the metal shaft 9 from overtraveling. When the metal shaft 9 rotates, it moves around the pivot point 16 as the center. The stop block 17 limits the range of movement of the metal shaft 9 to avoid misalignment when the SIM card is ejected or installed due to excessive range of movement.

[0022] The key design feature of this utility model is that the SIM card is automatically ejected by the cooperation of the metal pull rod 8 and the metal rotating shaft 9. When the user presses the end of the metal pull rod 8 that extends beyond the housing, it will push the metal pull rod 8 inside the card tray. The metal pull rod 8 moves inside the plastic body 2 and forms a lever or rotational connection with the card tray or related linkage mechanism through the metal rotating shaft 9. The linear motion of the pull rod is converted into the rotation or translational motion of the card tray through the rotating shaft, thereby pushing the SIM card out of the card slot for easy removal by the user and greatly improving the convenience of use. In addition, four terminal structures—first connection terminal 3, second connection terminal 4, third connection terminal 5, and fourth connection terminal 6—are added. These structures employ independent bending structures to provide stable, low-impedance electrical connections. Furthermore, the reaction force of the bending structures increases the connection stability between the terminals and the SIM card's metal contacts, reducing the probability of detachment or poor contact, thus ensuring the stability and reliability of SIM card data communication.

[0023] The operation process of this utility model is as follows: By applying force to the end of the metal pull rod 8 that extends beyond the housing, the metal pull rod 8 pushes the metal rotating shaft 9. By moving around the axis point 16 as the center, one end of the metal rotating shaft 9 forms a lever or rotates to push the installed SIM card out of the card holder, making it convenient for the user to remove. When the SIM card is installed, the metal rotating shaft 9 is pushed when the SIM card is pushed in, thereby causing the metal rotating shaft 9 to drive the metal pull rod 8 to reset, ready for the next use. To avoid accidental contact, a protective structure can be added to the end of the metal pull rod 8 that extends beyond the housing to prevent external pressure from causing the metal pull rod 8 to push the SIM card out.

[0024] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
