Description

Technical Field

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

[0002] The SIM card connector is a structural component used for positioning and reading information from the SIM card.

[0003] Publication (Announcement) No.: CN217239898U discloses a vibration-resistant SIM card connector, including a connector body. A card removal component is integrally connected and installed on the left side of the connector body. Both sides of the front surface of the connector body are provided with raised card tray insertion slots. A card tray is inserted into the card tray insertion slot, and a SIM card is inserted into the card tray. The added first limiting block and second limiting block are interlocked and locked together, which can realize an efficient and stable connection between the SIM card tray and the connector.

[0004] In existing patented SIM card connectors, a pivot is provided. This pivot has a cylindrical structure. Its bottom surface is limited by the PCB board to prevent the pivot from falling out of the pivot hole in the plastic body. Its surface surface is protected by an interference fit where the pivot size is designed to be larger than the pivot hole size. When the connector is used in the vibration environment of a car, the pivot may fall out after long-term vibration, causing the connector to malfunction. Therefore, we propose a vibration-resistant SIM card connector. Utility Model Content

[0005] The main objective of this invention is to provide a vibration-resistant SIM card connector. By designing the cylindrical shaft of the existing patented connector as a nail-shaped shaft, and simultaneously designing the shaft assembly hole in the connector body as a nail-shaped assembly hole for adaptation and assembly, the combination of the nail-shaped shaft and the nail assembly hole can effectively prevent the shaft from falling off from the upper surface of the connector body due to long-term use in a vibration environment when the connector body is subjected to vibration. This achieves vibration resistance and anti-detachment of the connector body, effectively solving the problems in the background technology.

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

[0007] A vibration-resistant SIM card connector includes a connector body, a pin-shaped pivot, and a pin-shaped assembly hole. A metal terminal is located in the center of the front surface of the connector body. A strip-shaped push rod A is movably inserted into the insertion channel of a card-removing assembly on one side of the connector body. The lower end of the push rod A protrudes outward from the mounting notch of the card-removing assembly on one side of the connector body and is inserted into a spring. A button is sleeved on the outer side of the bottom end of the push rod A extending from the spring. A push rod B is fitted inside the pivot seat of the card-removing assembly on one side of the connector body. A pin-shaped assembly hole is formed through the pivot seat surface outside the shaft hole on the surface of the push rod B. A pin-shaped pivot is installed between the pin-shaped assembly hole and the shaft hole on the surface of the push rod B. A PCB board that contacts the metal terminal is mounted on the surface of the connector body.

[0008] Furthermore, the double-end openings of the nail-shaped assembly hole are provided with tapered grooves;

[0009] By adopting the above technical solution, the tapered groove of the nail-shaped assembly hole can be adapted to the nail-shaped rotating shaft for interference fit assembly.

[0010] Furthermore, a nail-tail cone block with a nail-shaped rotating shaft is inserted into the tapered groove of the nail-shaped assembly hole;

[0011] By adopting the above technical solution, the nail tail cone block of the nail-shaped rotating shaft increases the contact vibration-resistant position by making large-area contact with the tapered groove of the nail-shaped assembly hole.

[0012] Furthermore, the nail-shaped rotating shaft has a tapered head at the outer shaft end away from its own nail tail cone block;

[0013] By adopting the above technical solution, the nail-shaped rotating shaft with a tapered head can easily pass through the nail-shaped assembly hole and push rod B.

[0014] Furthermore, the diameter of the nail-shaped rotating shaft is smaller than the diameter of the surface shaft hole of the push rod B;

[0015] By adopting the above technical solution, push rod B can rotate flexibly on the outside of the nail-shaped rotating shaft through the shaft hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This utility model designs the cylindrical rotating shaft of the existing patented connector as a nail-shaped rotating shaft, and at the same time designs the rotating shaft assembly hole in the connector body that mates with it as a nail-shaped assembly hole for adaptation and assembly. When the connector body is subjected to vibration, the combination of the nail-shaped rotating shaft and the nail assembly hole can effectively prevent the rotating shaft from falling off from the upper surface of the connector body due to long-term use in a vibration environment, thereby achieving vibration resistance and anti-fall-off of the connector body.

[0018] Furthermore, the taper head of the nail-shaped swivel can easily pass through the nail-shaped assembly hole and push rod B. The nail tail cone of the nail-shaped swivel has a large contact area with the taper groove of the nail-shaped assembly hole to increase the contact vibration-resistant position and ensure the connector body is vibration-resistant and prevents it from falling off.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-5 As shown, a vibration-resistant SIM card connector includes a connector body 1, a pin-shaped rotating shaft 7, and a pin-shaped assembly hole 8. A metal terminal 2 is provided in the center of the front surface of the connector body 1. A strip-shaped push rod A3 is movably inserted into the insertion channel of the card-removing assembly on one side of the connector body 1. The lower end of the push rod A3 protrudes outward from the mounting notch of the card-removing assembly on one side of the connector body 1 and is inserted into a spring 4. A button 5 is sleeved outside the bottom end of the push rod A3 extending from the spring 4. A push rod B6 is fitted inside the rotating shaft seat of the card-removing assembly on one side of the connector body 1. A pin-shaped assembly hole 8 is provided through the rotating shaft seat surface outside the shaft hole on the surface of the push rod B6. A pin-shaped rotating shaft 7 is installed between the pin-shaped assembly hole 8 and the shaft hole on the surface of the push rod B6. A PCB board 9 that contacts the metal terminal 2 is mounted on the surface of the connector body 1.

[0027] The nail-shaped assembly hole 8 has tapered grooves at both ends.

[0028] By adopting the above technical solution, the tapered groove of the nail-shaped assembly hole 8 can be adapted to the nail-shaped rotating shaft 7 for interference fit assembly.

[0029] The nail-shaped rotating shaft 7 has a nail-tail cone block inserted into the tapered groove of the nail-shaped assembly hole 8.

[0030] By adopting the above technical solution, the nail tail cone block of the nail-shaped rotating shaft 7 increases the contact vibration-resistant position by making large-area contact with the tapered groove of the nail-shaped assembly hole 8.

[0031] Among them, the outer shaft end of the nail-shaped rotating shaft 7, which is away from its own nail tail cone block, is provided with a tapered head;

[0032] By adopting the above technical solution, the nail-shaped rotating shaft 7 can easily pass through the nail-shaped assembly hole 8 and the push rod B6 with its tapered head.

[0033] Wherein, the shaft diameter of the nail-shaped rotating shaft 7 is smaller than the surface shaft hole diameter of the push rod B6;

[0034] By adopting the above technical solution, the push rod B6 can rotate flexibly on the outside of the nail-shaped rotating shaft 7 through the shaft hole.

[0035] It should be noted that this utility model is a vibration-resistant SIM card connector. After the hardware terminal 2 is set on the middle surface of the connector body 1, the push rod 3 extends out along the installation notch inside the insertion channel of the card removal assembly on one side of the connector body 1 and inserts the spring 4 and the button 5. Then, the push rod B6 is installed in the rotating seat of the card removal assembly on one side of the connector body 1. After the nail-shaped rotating shaft 7 passes through one end of the nail-shaped assembly hole 8, it continues to pass through the shaft hole of the push rod B6 and then exits from the other end of the nail-shaped assembly hole 8. At this time, the nail tail cone of the nail-shaped rotating shaft 7 increases the contact vibration-resistant position by making a large-area interference contact with the tapered groove of the nail-shaped assembly hole 8. Then, the PCB board 9 can be installed at the connector body 1 and contact the hardware terminal 2 in the same way as in the existing patent technology. When the connector body 1 is subjected to vibration, the combination of the nail-shaped rotating shaft 7 and the nail assembly hole 8 can effectively prevent the rotating shaft from falling off from the upper surface of the connector body 1 due to long-term use in a vibration environment, thus realizing the vibration resistance and anti-fall-off of the connector body 1.

[0036] It should be noted that this utility model is a vibration-resistant SIM card connector. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
