Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and particularly relates to an improved terminal structure of a Micro SD7.10 card seat connector. Background Art

[0002] The Micro SD card is an extremely small flash memory card. Originally, this memory card was called T-Flash, and later renamed Trans Flash. The reason for the re-renaming to Micro SD is that it was adopted by the SD Association. Other memory cards adopted by the SDA include Mini SD and SD cards. It is mainly applied to mobile phones. However, due to its tiny volume and continuously increasing storage capacity, it has been used in GPS devices, portable music players, and some flash memory disks, with very wide applications.

[0003] The publication number CN216598046U discloses a card seat connector for a MicroSD7.10 card. After the lower row of contact terminals is fixed on the plastic body, the contact points of the lower row of contact terminals of the MicroSD7.10 card and the contact points of the lower row of contact terminals of the MicroSD4.0 card are respectively independent and do not interfere with each other with the force-bearing support points of the lower row of contact terminals of the MicroSD7.10 card and the force-bearing support points of the lower row of contact terminals of the MicroSD4.0 card, achieving that the MicroSD7.10 card connector can be compatible with the MicroSD4.0 card, making the compatibility better and the application more extensive.

[0004] The existing Micro SD cards have the following disadvantages during use: The spring piece of the Micro SD4.0 terminal is formed by stretching in the middle of the spring piece of the MicroSD7.1 terminal. The width of the spring piece of the Micro SD4.0 terminal is the same as the width of the opening generated in the middle of the spring piece of the MicroSD7.1 terminal after stretching. When the connector is inserted into the card, the spring piece of the Micro SD4.0 terminal is pressed down by the card, and the front head is pressed into the opening generated in the middle of the spring piece of the Micro SD7.1 terminal below it. Since their widths are the same and there is no gap, it may cause the spring piece of the Micro SD4.0 terminal to be clamped in the opening and unable to rebound to its original height after the card is taken out, affecting the contact function. For this reason, we propose an improved terminal structure of a Micro SD7.10 card seat connector. Content of the Utility Model

[0005] The main purpose of the present utility model is to provide an improved terminal structure for a Micro SD7.10 card socket connector. By opening concave holes and expansion slots at positions corresponding to the positions where the elastic pieces of the Micro SD4.0 terminal may be clamped on the elastic pieces of the Micro SD7.1 terminal, and making its width greater than that of the elastic pieces of the Micro SD4.0 terminal, it can prevent being clamped, and effectively solve the problems in the background technology.

[0006] To achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0007] An improved terminal structure for a Micro SD7.10 card socket connector, including an iron shell, and further including a plastic body and a hardware terminal. The iron shell is arranged on the top of the plastic body, and the hardware terminal is arranged inside the plastic body. The hardware terminal includes a lower row of contact terminals, a lower row of contact terminals for the MicroSD7.10 card, a connecting contact piece, a lower row of contact terminals for the MicroSD4.0 card, a concave hole and an expansion slot. The lower row of contact terminals is arranged on the surface of the plastic body, and the lower row of contact terminals for the MicroSD7.10 card is arranged at the end of the lower row of contact terminals. The connecting contact piece is arranged on the surface of the lower row of contact terminals, and the lower row of contact terminals for the MicroSD4.0 card is arranged at the end of the connecting contact piece. A concave hole is opened at a position corresponding to the lower row of contact terminals for the MicroSD4.0 card inside the lower row of contact terminals, and expansion slots are opened on both sides of the end of the lower row of contact terminals at positions corresponding to the concave hole.

[0008] Furthermore, it further includes a self - elastic mechanism. The self - elastic mechanism is arranged on the side inside the plastic body. The self - elastic mechanism includes a slider, a spring and a pull rod. The spring is installed on the side of the plastic body, and the slider is arranged at the end of the spring. A pull rod is installed between the end of the slider close to the spring and the plastic body; the self - elastic mechanism composed of the slider, the spring and the pull rod facilitates the limit fixation of the card and avoids the card from popping out.

[0009] Furthermore, an upper row of contact terminals corresponding to the position of the lower row of contact terminals is arranged on one side of the surface of the plastic body, and the upper row of contact terminals for the MicroSD7.10 card and the upper row of contact terminals for the MicroSD4.0 card are arranged at the end of the upper row of contact terminals; the docking with the card body is realized through the upper row of contact terminals.

[0010] Furthermore, welding pins are arranged at the ends of both the lower row of contact terminals and the upper row of contact terminals; the welding pin structure plays a role in connecting communication.

[0011] Compared with the prior art, the utility model has the following beneficial effects: A concave hole structure is formed at the corresponding position of the surface of the lower row of contact terminals and the lower row of contact terminals of the MicroSD4.0 card. When the connector is inserted into the card, the elastic piece of the lower row of contact terminals of the Micro SD4.0 is pressed downward by the card, and the front end part is pressed into the concave hole. Since expansion slots are provided on both sides of the concave hole, the aperture specification is greatly increased, making it larger than the outer diameter specification of the lower row of contact terminals of the Micro SD4.0. Therefore, there will be a gap at the connection after being snapped in, avoiding the problem that the lower row of contact terminals of the Micro SD4.0 is clamped when taken out, resulting in the inability to rebound to the original height after taking out the card and affecting the contact function.

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation modes.

[0021] As Figures 1-7 shown, an improved Micro SD7.10 card socket connector terminal structure includes an iron shell 1, and also includes a plastic body 2 and a hardware terminal 3. The iron shell 1 is arranged on the top of the plastic body 2, and the hardware terminal 3 is arranged inside the plastic body 2. The hardware terminal 3 includes a lower row of contact terminals 32, a lower row of contact terminals 35 for MicroSD7.10 card, a connecting contact piece 36, a lower row of contact terminals 37 for MicroSD4.0 card, a concave hole 38 and an expansion slot 39. The lower row of contact terminals 32 is arranged on the surface of the plastic body 2, and the lower row of contact terminals for MicroSD7.10 card 35 is arranged at the end of the lower row of contact terminals. The connecting contact piece 36 is arranged on the surface of the lower row of contact terminals 32, and the lower row of contact terminals 37 for MicroSD4.0 card is arranged at the end of the connecting contact piece 36. Concave holes 38 are opened at positions corresponding to the lower row of contact terminals 37 for MicroSD4.0 card inside the lower row of contact terminals 32, and expansion slots 39 are opened on both sides of the end of the lower row of contact terminals 32 at positions corresponding to the concave holes 38.

[0022] Among them, it also includes a self-elastic mechanism 4. The self-elastic mechanism 4 is arranged on the side inside the plastic body 2. The self-elastic mechanism 4 includes a slide block 41, a spring 42 and a pull rod 43. The spring 42 is installed on the side of the plastic body 2, and the slide block 41 is arranged at the end of the spring 42. A pull rod 43 is installed between the end of the slide block 41 close to the spring 42 and the plastic body 2; the self-elastic mechanism 4 composed of the slide block 41, the spring 42 and the pull rod 43 facilitates the limit fixation of the card and avoids the card from popping out.

[0023] Wherein, on one side of the surface of the plastic body 2, there is an upper row of contact terminals 31 corresponding to the position of the lower row of contact terminals 32. At the end of the upper row of contact terminals 31, there are upper row of contact terminals 34 of the MicroSD7.10 card and the MicroSD4.0 card. Welding pins 33 are provided at the ends of both the lower row of contact terminals 32 and the upper row of contact terminals 31. The docking with the card body is achieved through the upper row of contact terminals 31, and the structure of the welding pins 33 plays a role in connecting communication.

[0024] It should be noted that the present utility model is an improved terminal structure of a Micro SD7.10 card socket connector. When in use, a concave hole 38 structure is formed at the corresponding position on the surface of the lower row of contact terminals 32 and the lower row of contact terminals 37 of the MicroSD4.0 card. When the connector is inserted into the card, the elastic piece of the lower row of contact terminals 37 of the Micro SD4.0 is pressed downward by the card, and the front end is pressed into the inside of the concave hole 38. Since expansion slots 39 are provided on both sides of the concave hole 38, the aperture specification is greatly increased, making its specification larger than the outer diameter specification of the lower row of contact terminals 37 of the Micro SD4.0. Therefore, there will be a gap at the connection after being snapped in, avoiding the problem that the lower row of contact terminals 37 of the Micro SD4.0 is clamped when taking out the card, resulting in the inability to rebound to the original height after taking out the card and affecting the contact function.
