Description

Technical Field

[0001] This utility model relates to the field of mobile phone connectors, specifically a multi-insulated mobile phone connector. Background Technology

[0002] As smartphones continue to evolve towards thinner, lighter, and more functional designs (such as enhanced fast charging technology, high-speed data transmission, and multi-interface integration), their internal connectors, as key components for current and signal transmission, are playing an increasingly important role. Under this trend, the requirements for the insulation performance of connectors are constantly increasing to ensure safe current transmission and prevent short circuits.

[0003] Traditional connectors with multi-layered insulating shells are often fixed with a single clip or screw, which is prone to loosening under long-term use or vibration. This leads to increased gaps between the insulating layers, which not only reduces insulation resistance but may also cause leakage risks. At the same time, the existing fixing structures of insulating shells (such as injection molding or multi-screw fastening) are not convenient for installation and maintenance. Special tools are required for disassembly, and the insulating layers or internal terminals are easily damaged, increasing maintenance costs. Therefore, we propose a multi-layered insulating connector specifically for mobile phones. Utility Model Content

[0045] Structural Description:

[0046] Connector body 1: As the core component connecting the mobile phone to external devices (such as chargers and computers), the whole is a small structure adapted to the mobile phone interface / cable end. The built-in conductive module realizes current and signal transmission, provides the installation foundation for external insulation protection and mechanical connection structure, and is the key carrier for establishing the path between the mobile phone and the device.

[0047] Insulating shell 1 2: As an insulating shell on one side of the connector body 1, it has an overall shell-shaped structure that is adapted to the outer side of the insulating sleeve 8. The inner side can be snapped into the insulating sleeve 8, and it cooperates with the insulating shell 2 6 to form double insulation. The retaining strip 11 on its edge is used for connection and fixation.

[0048] Connector housing 3: As a protective structure for the connector, it is a hollow structure with openings on both adjacent sides. The two housings can be fitted onto the outside of the connector. When closed, they cover the connector to provide protection. The opening design makes the connector easy to use.

The inner side can be snapped into the insulating sleeve 8, and it cooperates with the insulating shell 1 2 to form an integral insulating shell. The slot 10 on it is used for connection and fixation.

[0052] C-shaped plate 7: As the core component of the fastening structure, it has an overall "C" shaped plate structure and can be inserted into multiple slots. By cooperating with the slots, it fixes the insulating shells 1-2, 2-6 and the locking strip 11. The embedded design ensures a flat surface.

[0053] Insulating sleeve 8: As the first layer of insulation barrier, it has a tubular or sleeve-shaped structure and tightly wraps around the outside of the connector body 1. The connection port passes through its outside, which plays the role of isolating the body from the external environment.

[0054] Stepped shaft 9: As a motion control component for the connector housing, it is a shaft structure with a stepped diameter. The small end is fixed to the connecting rod 4 and can slide and rotate in the stepped slide groove 5, driving the connector housing 3 to move and flip.

[0055] Slot 10: As a connecting slot between insulating shell 1 and 2, it is a slot-shaped structure opened on both sides of insulating shell 2 6, with the side closer to insulating shell 1 2 penetrating through, used to accommodate the card strip 11 to achieve the connection between the two.

[0056] Strip 11: As a connecting strip between insulating shell 1 and 2, it is a strip-shaped structure fixed on both sides of insulating shell 1 2, located at one end near insulating shell 2 6, and can overlap with the slot 10 to achieve a sealed connection;

[0057] Square groove 12: As the second fastening structure, the groove is a square groove structure opened on the side of the clip 11 away from the main body, located between adjacent semi-square grooves 13, and is used to accommodate the C-shaped plate 7 for auxiliary fixing.

[0058] Semi-square groove 13: As the first fastening structure, the groove is a semi-square groove structure opened on the contact surface between the clip 11 and the outer shell 2. Multiple grooves are evenly distributed and correspond to the slot 2 15. They are used in conjunction with the C-shaped plate 7 to achieve fixation.

[0059] Main slot 14: As a side slot for the C-shaped plate, it is a groove-shaped structure opened on the side of the slot 10 away from the main body, corresponding to the semi-square slot 13 and slot 17 respectively, and is used to accommodate the auxiliary fixation of the side of the C-shaped plate 7.

[0060] Slot 2 15: As the corresponding slot of the first fastening structure, it is a slot-shaped structure opened on the opposite side of the insulating shell 2 6 and the semi-square slot 1 13. The number and position are corresponding, and it is connected with the semi-square slot 1 13 and the C-shaped plate 7.

[0061] Semi-square groove 2 16: As the other side slot of the C-shaped plate, the whole is a semi-square groove structure opened on the side of slot 2 15 away from the main body. It is located on the side of slot 2 15 away from semi-square groove 13 and is used to accommodate the auxiliary connection of the side of C-shaped plate 7.

[0062] Slot 17: As the corresponding slot of the second locking structure, it is a slot-shaped structure opened on the side of the square slot 12 away from the main body. It is located on the side of the square slot 12 away from the outer shell 2, corresponding to the main slot 14, and is fixed in conjunction with the C-shaped plate 7.

[0063] Working Principle: First, the connector body 1 is tightly wrapped with an insulating sleeve 8, forming the first layer of insulation barrier, directly isolating the connector body 1 from the external environment. Next, the insulating sleeve 8 is wrapped from both sides by insulating outer shell 2 and insulating outer shell 6, forming the second layer of insulation. The locking strip 11 on insulating outer shell 2 and the locking groove 10 on insulating outer shell 6 overlap, achieving not only initial connection but also a tight seal, further enhancing insulation performance. Then, to ensure a stable connection between insulating outer shell 2 and insulating outer shell 6, the semi-square groove 13 on locking strip 11 corresponds to the slot 15 on insulating outer shell 6, with the middle side of the C-shaped plate 7 embedded therein. Simultaneously, the two sides of the C-shaped plate 7 are inserted into the semi-square groove 16 and the main slot 14 of the locking groove 10 on insulating outer shell 6, forming a three-dimensional fixation. Between adjacent first-locking structures, second-locking structures are alternately distributed, with C-shaped plates 7 also inserted into the square groove 12 on locking strip 11. The slots 17 and 14 of the card slot 10 are inserted into the card strip 11 on both sides respectively. This multi-point alternating fixation effectively disperses external forces and avoids loosening caused by long-term use or vibration. The entire fixing process does not require special tools and can be completed by simply inserting and removing the C-shaped plate 7. At the same time, two connector housings 3 are sleeved on the outside of the connector body 1 connection port. They are connected to the insulating housing 1 2 and insulating housing 2 6 through the connecting rod 4. The stepped shaft 9 on the connecting rod 4 is slidably engaged with the stepped slide groove 5 on the insulating housing 1 2 and insulating housing 2 6. The stepped structure can prevent the stepped shaft 9 from axially disengaging, ensuring that the connector housing 3 stably covers the connection port and plays a targeted insulation protection role. When the connection port needs to be used, push the connecting rod 4 to make the stepped shaft 9 slide along the stepped slide groove 5, causing the two connector housings 3 to separate. When sliding to the end of the slide groove, the stepped shaft 9 can rotate, flipping the connector housing 3 open to expose the connection port. When not in use, the reverse operation can close the connector housing 3 to continue protecting the connection port.
