Description

Technical Field

[0001] This utility model belongs to the field of electrical connector technology, specifically relating to a charging connector with a U-shaped slot structure. Background Technology

[0002] With the increasing variety of electronic devices and their usage scenarios, charging connectors, as crucial components for power connection and data transmission, are widely used in mobile phones, tablets, laptops, smart wearable devices, and various portable electronic products. Traditional charging connectors mostly adopt plug-in or direct soldering structures, with their core function being to achieve electrical connection and mechanical fixation. However, existing charging connectors still have significant shortcomings in terms of structural design, operational stability, and adaptability.

[0003] Traditional plug-in connectors mostly rely on the frictional engagement between the socket and pins to achieve connection, lacking a dedicated locking structure. This makes the charging cable head prone to loosening, shaking, or even detachment during connection. Under conditions of vibration, tension, or frequent use, the connector's poor stability can easily lead to poor power contact, affecting the normal charging or operation of the device.

[0004] Some charging connectors use permanent fixing methods, such as adhesive bonding, ultrasonic welding, or structural riveting. While these methods improve the connection strength to some extent, they are not conducive to later maintenance, cable replacement, or connector reinstallation. Once the charging cable is damaged, the entire assembly needs to be replaced, which increases maintenance costs and does not conform to the principle of sustainable use.

[0005] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0006] In view of the technical problems mentioned in the background art, the purpose of this utility model is to provide a charging connector with a U-shaped card slot structure to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a charging connector with a U-shaped slot structure, comprising a mounting base and a charging cable head. The mounting base includes a mounting plate, an upper cover, and a lower cover. The upper cover is mounted on the upper end of the mounting plate, and the lower cover is mounted on the lower end of the mounting plate. The surface of the mounting plate is recessed with a cable-locking groove, and one end of the cable-locking groove has a cable-locking opening. The charging cable head is engaged in the cable-locking groove through the cable-locking opening.

[0008] Furthermore, the inner surface of the cable slot is provided with a cable-locking groove, and an elastic plate that can be elastically deformed is provided in the cable-locking groove. The end of the elastic plate is provided with a locking protrusion, and the lower end of the charging cable head is provided with a locking groove. Under the action of the elastic plate, the locking protrusion pops out and embeds into the locking groove of the charging cable head to achieve a locking connection and fixation.

[0009] Furthermore, both the locking protrusion and the locking groove are arc-shaped.

[0010] Furthermore, the surface of the top cover is provided with a U-shaped wire end groove, the inner edge of the wire end groove is provided with a wire end pressing edge, and the upper edge of the charging cable end is provided with a wire end recess. The position of the wire end recess corresponds to the wire end pressing edge, and the wire end pressing edge is pressed into the wire end recess.

[0011] Furthermore, the slot for the card is a U-shaped slot.

[0012] Furthermore, the surface of the mounting plate is evenly provided with several wire-clamping grooves, and the multiple wire-clamping grooves are arranged along the length direction of the mounting plate. Each wire-clamping groove can be used to clamp and install an independent charging cable head.

[0013] Furthermore, the mounting plate is provided with symmetrical fixing lugs on the left and right sides, the upper cover is provided with symmetrical fixing posts on the inner left and right sides, and the lower cover is provided with symmetrical fixing holes on the inner left and right sides. The fixing posts and fixing holes are respectively located at the upper and lower ends of the fixing lugs, and are connected and fixed by fasteners passing through the fixing holes, fixing lugs and fixing posts in sequence.

[0014] The present invention has the following advantages: The surface of the mounting plate is recessed with a U-shaped cable-holding groove, one end of which has a cable-holding opening. The charging cable head is engaged and confined within the cable-holding groove through this opening. The inner surface of the cable-holding groove has a cable-holding slot, within which is an elastically deformable plate. The end of the elastic plate has a protruding arc-shaped locking protrusion, and the lower end of the charging cable head has a recessed arc-shaped locking groove. Under the action of the elastic plate, the locking protrusion pops out and embeds into the locking groove of the charging cable head, achieving a secure connection. The U-shaped cable-holding groove structure of the present invention, through the U-shaped cable-holding groove combined with the elastic plate and locking protrusion, achieves a stable connection of the charging cable head, ensuring reliable connection, preventing loosening, easy assembly, quick disassembly and assembly, convenient maintenance and replacement, and suitability for mass production, effectively reducing manufacturing and usage costs.

Detailed Implementation

[0022] like Figures 1 to 6 As shown, a charging connector with a U-shaped slot structure includes a mounting base 10 and a charging cable head 20. The mounting base 10 includes a mounting plate 11, an upper cover 12, and a lower cover 13. The upper cover 12 covers the upper end of the mounting plate 11, and the lower cover 13 covers the lower end of the mounting plate 11. The surface of the mounting plate 11 is recessed with a U-shaped cable-holding groove 111, which forms an accommodating space for limiting the charging cable head 20. One end of the cable-holding groove 111 has a cable-holding opening 112, the size of which is slightly larger than the diameter of the charging cable head 20, facilitating the insertion of the charging cable head 20 into the cable-holding groove 111 from the side. The charging cable head 20 is snapped into and confined in the cable slot 111 through the cable opening 112. After insertion, it is further secured by the cover 12 and the cover 13 to prevent the charging cable head from shaking or loosening, thereby improving the stability and reliability of the connector.

[0023] In practical implementation, the inner surface of the cable slot 111 is provided with a cable-locking groove 113, and an elastically deformable retaining plate 114 is provided inside the cable-locking groove 113, which has good deformation recovery performance. The end of the elastic retaining plate 114 is provided with an arc-shaped retaining protrusion 115, which protrudes into the cable slot 111. The lower end of the charging cable head 20 is recessed with an arc-shaped retaining groove 21 that matches the retaining protrusion 115. When the charging cable head 20 is inserted into the cable slot 111 along the cable-locking opening 112 and pushed into the groove to a preset position, the retaining protrusion 115 pops out under the action of the elastic retaining plate 114 and embeds into the retaining groove 21 of the charging cable head 20, realizing a locking connection and fixation. This structure ensures that the charging cable head 20 has good positioning and limiting function in the slot, and will not easily come out when pulled by external force. When disassembly is required, only slight external pressure deformation of the elastic plate 114 is needed to release the engagement, facilitating maintenance and replacement. Through the above structure, a stable and detachable mechanical connection of the charging cable head is achieved, enhancing the product's safety, practicality, and reusability.

[0024] In practical implementation, the surface of the upper cover 12 is provided with a U-shaped wire end groove 121, which is vertically aligned with the wire clamping groove 111 to limit and press-fit the charging cable 20 in the upward direction. The inner edge of the wire end groove 121 is provided with a wire end pressing edge 122, and the upper edge of the charging cable 20 is provided with a wire end recess 22. The position of the wire end recess 22 corresponds to the wire end pressing edge 122, and their shapes are matched. When the charging cable head 20 is inserted into the cable slot 111 of the mounting plate 11 and the top cover 12 is closed, the cable head pressing edge 122 is pressed into the cable head recess 22, thereby achieving a stable locking engagement in the upward direction. This structure further achieves the following technical effects: enhancing the upper and lower clamping force, preventing the charging cable head 20 from being lifted or vibrated in the vertical direction due to external force, ensuring accurate positioning and avoiding misalignment or rotation during installation, and achieving triple fixation in conjunction with the elastic clamping plate 114 and the locking protrusion 115 structure, significantly improving connection stability and safety.

[0025] In a second embodiment of the mounting base 10, the mounting base 10 is designed to accommodate multiple sets of charging cable heads 20. The surface of the mounting plate 11 is uniformly provided with several cable-holding grooves 111, arranged along the length of the mounting plate 11. Each cable-holding groove 111 can hold and install an independent charging cable head 20, thereby fulfilling the needs of multi-interface output or multi-device charging. The upper cover 12 is fitted onto the upper end of the mounting plate 11, and the lower cover 13 is fitted onto the lower end of the mounting plate 11, forming an overall enclosed structure to improve structural strength and appearance integrity. The surface of the top cover 12 is evenly provided with several wire end slots 121. Each wire end slot 121 corresponds to a charging wire end 20 in the lower wire slot 111. When the cover is closed, the wire end pressing edges in the multiple wire end slots 121 are respectively pressed into the wire end recesses corresponding to the charging wire ends 20, ensuring that each charging wire end is in a stable and locked state. Not limited by the number of wire ends in a single structure, the number of wire ends can be flexibly increased or decreased according to specific charging needs. All wire ends are arranged in a modular manner and can be freely combined to adapt to different charging standards and interface layout requirements. It is suitable for the development of charging devices with centralized bases, such as multi-device chargers, desktop integrated interface modules, and plug-in charging platforms.

[0026] In practical implementation, to ensure reliable fixation of the upper cover 12 and the lower cover 13 on the mounting plate 11, the mounting plate 11 is symmetrically provided with fixing lugs 116 on the left and right sides, the upper cover 12 is symmetrically provided with fixing posts 123 on the inner left and right sides, and the lower cover 13 is symmetrically provided with fixing holes 131 on the inner left and right sides. During assembly, the fixing posts 123 and the fixing holes 131 are respectively located at the upper and lower ends of the fixing lugs 116, and are connected and fixed by fasteners passing through the fixing holes 131, the fixing lugs 116 and the fixing posts 123 in sequence, thereby achieving a firm assembly between the upper cover 12, the lower cover 13 and the mounting plate 11, ensuring a firm connection and preventing the upper or lower cover from falling off or loosening due to vibration or external force; the symmetrical structural design facilitates assembly and improves production efficiency.

[0027] In summary, the surface of the mounting plate 11 is recessed with a U-shaped cable-holding groove 111. One end of the cable-holding groove 111 has a cable-holding opening 112. The charging cable head 20 is engaged and confined within the cable-holding groove 111 through the cable-holding opening 112. The inner surface of the cable-holding groove 111 has a cable-holding slot 113. An elastically deformable retaining plate 114 is provided within the retaining slot 113. The end of the elastic retaining plate 114 has an arc-shaped retaining protrusion 115. The charging cable head 20... The lower end is recessed with an arc-shaped locking groove 21. The locking protrusion 115 pops out under the action of the elastic locking plate 114 and is embedded in the locking groove 21 of the charging cable head 20 to achieve a locking connection and fixation. The charging connector of this utility model with U-shaped locking groove structure achieves a stable locking of the charging cable head through the U-shaped locking groove, the elastic locking plate and the locking protrusion. The connection is reliable, not easy to loosen, easy to assemble, quick to disassemble and assemble, easy to maintain and replace, suitable for mass production, and effectively reduces manufacturing and use costs.
