Technical Field

[0001] This application relates to the field of electrical connector technology, and more particularly to a socket wire clamping structure and a socket having the same. Background Technology

[0002] Currently, in the field of wiring devices, especially in the technology of securing cables to sockets, clamping-type fixing is commonly used. Specifically, this fixing method typically includes an insulating housing with an inlet hole for external wires and an electrical contact element containing a wire channel for accommodating the wires. Next to the electrical contact element, a spring is usually provided, which is electrically connected to the electrical contact element to achieve clamping and fixing of the wires.

[0003] However, in the existing technology, when connecting the conductive wire into the electrical connector, it is necessary to use external tools (such as screwdrivers or special clamps) to open the internal clamping spring, and then clamp the end of the conductive wire between the spring and the conductor. This process is not only cumbersome, but also reduces the wiring efficiency. Utility Model Content

[0006] Furthermore, the adjustment assembly also includes: a base, on which the adjustment structure is retractably mounted; and an elastic structure disposed within the base to apply an elastic force to the adjustment structure on the side away from the elastic sheet.

[0027] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] To address the issue that cable fixing methods in related technologies require external tools, thus affecting wiring efficiency, this application provides a socket wire clamping structure and a socket having the same.

[0029] like Figures 1 to 3As shown, the socket clamping structure includes a mounting bracket 10, a spring sheet 20, and an adjustment assembly 30. The mounting bracket 10 has a mounting cavity 11 and a limiting portion 12. The spring sheet 20 is disposed on the mounting bracket 10, with at least a portion extending into the mounting cavity 11 to clamp the cable 40 extending into the mounting cavity 11. The limiting portion 12 engages with the spring sheet 20 to connect the spring sheet 20 and the mounting bracket 10. The adjustment assembly 30 includes a movably disposed adjustment structure 31 for pushing the spring sheet 20 away from the cable 40.

[0030] Applying the technical solution of this embodiment, at least a portion of the elastic piece 20 extends into the mounting cavity 11. Without external force, its inherent elasticity allows it to press the cable 40 inserted into the mounting cavity 11, enabling cable connection to be completed manually without additional tools. This solves the problem in related technologies where cable fixing methods require external tools, affecting wiring efficiency. When cable disassembly is required, the elastic piece 20 is pushed apart from the cable 40 by adjusting the adjustment structure 31 in the adjustment assembly 30, again without the need for external tools. This significantly simplifies wiring operations and improves efficiency. Simultaneously, the limiting part 12 and the elastic piece 20 work together to ensure the elastic piece's position is stable when pressing the cable, preventing displacement due to prolonged use or minor external vibrations. This ensures the stability and reliability of the cable-socket connection, helps prevent accidental cable detachment during connection, and enhances the overall structural safety.

[0031] In this embodiment, the adjustment assembly 30 further includes a base and an elastic structure. The adjustment structure 31 is retractably mounted on the base. Pressing the adjustment structure 31 moves the elastic piece 20, separating it from the cable 40. The elastic structure is located within the base to apply an elastic force to the adjustment structure 31, moving it away from the elastic piece 20. Thus, the retractable adjustment structure 31 allows the user to directly move the elastic piece 20 by pressing the adjustment structure 31, releasing the pressure of the elastic piece 20 on the cable 40. This easily separates the cable from the socket, avoiding the inconvenience of using tools like screwdrivers in traditional wiring methods, simplifying the cable disassembly process, and providing users with a more efficient and convenient operation.

[0032] Specifically, the elastic structure within the housing applies an elastic force to the adjustment structure 31 on the side away from the elastic plate 20. When the user completes the cable disconnection and releases the adjustment structure 31, the elastic force causes it to automatically reset to its initial state without requiring additional user intervention, thus achieving the automatic reset function of the adjustment component 30. This feature not only makes the operation process smoother but also avoids the problem of forgetting to reset and affecting subsequent wiring operations, enhancing system reliability and user experience.

[0033] In this embodiment, the limiting part 12 includes an extension arm extending along a preset direction and a first limiting component. The first limiting component includes a first sub-limiting part and a second sub-limiting part. The first sub-limiting part is disposed on the extension arm, and the second sub-limiting part is disposed on the elastic sheet 20. One of the first and second sub-limiting parts is a first protrusion, and the other is a first recess. The first protrusion extends into the first recess to limit and stop the first recess. The preset direction is set at an angle to the extension / retraction direction of the adjustment structure 31. Thus, the first sub-limiting part on the extension arm and the second sub-limiting part on the elastic sheet 20 cooperate with each other, with one being a first protrusion and the other a first recess, the first protrusion extending into the first recess to limit and stop the first recess. This design can precisely limit the range of motion of the elastic sheet 20 relative to the mounting bracket, avoiding excessive offset or vibration of the elastic sheet during operation, thereby greatly increasing the stability of cable clamping and ensuring the quality and reliability of the electrical connection.

[0034] In this embodiment, a certain angle is set between the preset direction and the extension / retraction direction of the adjustment structure 31. This ensures that when the adjustment structure 31 pushes the elastic piece 20 to separate from the cable, there will be no large operating resistance or accidental disengagement between the elastic piece and the limiting part due to directional conflict. Thus, the above-mentioned directional design ensures the smoothness of the adjustment structure 31's operation on the one hand, and improves the safety of operation on the other.

[0035] like Figure 1 As shown, the mounting bracket 10 includes a first plate 13, a second plate 14, and a third plate 15 connected in sequence. The first plate 13 and the third plate 15 are arranged opposite to each other, and the first plate 13 and the second plate 14, as well as the second plate 14 and the third plate 15, are arranged at included angles. An extension arm is provided on the first plate 13 and / or the third plate 15. This arrangement of included angles between the first plate 13, the second plate 14, and the third plate 15 optimizes the internal spatial layout of the socket, reduces the floor space occupied, and makes the overall structure of the mounting bracket 10 more compact. This effectively saves installation space and improves the integration and design flexibility of the equipment.

[0036] In this embodiment, the relative arrangement of the first plate 13 and the third plate 15, combined with the angled connection between them and the second plate 14, forms a triangular stable structure, which can significantly increase the structural strength of the mounting bracket 10, enabling it to maintain high stability when subjected to external pressure or impact, reducing the risk of structural deformation or damage caused by external forces, and extending the service life of the socket.

[0037] Optionally, the limiting part 12 further includes a second limiting component, which includes a third sub-limiting part and a fourth sub-limiting part. The third sub-limiting part is disposed on the first plate 13 and / or the third plate 15, and the fourth sub-limiting part is disposed on the elastic sheet 20. One of the third and fourth sub-limiting parts is a second protrusion, and the other is a second recess. The second protrusion extends into the second recess to limit and stop against it. Thus, the above-mentioned arrangement of the second limiting component ensures that the elastic sheet 20 is limited not only in the preset direction by the first limiting component but also in other directions (usually perpendicular to the preset direction) by the second limiting component. This multi-directional limiting design effectively prevents excessive displacement of the elastic sheet in various directions, ensuring its precise position during wire pressing and releasing, and avoiding positional shift of the elastic sheet during long-term use or under the influence of the external environment. This significantly improves the stability and reliability of the entire socket wire pressing structure, ensuring the continuity and safety of the electrical connection.

[0038] In this embodiment, by providing a third sub-limiting part on the first plate 13 and / or the third plate 15, and a fourth sub-limiting part on the elastic sheet 20, the refined operation control design ensures that the movement of the elastic sheet 20 is more precise and controllable when the user operates using the adjustment structure 31. Specifically, when the user needs to tighten or release the cable, the limiting stop between the second protrusion and the second recess ensures that the deformation of the elastic sheet 20 is within a safe and effective range, avoiding damage or failure caused by excessive deformation of the elastic sheet during operation. This also makes the operation process more intuitive and easier to master, enhancing the user's operating experience and user-friendliness.

[0039] like Figure 1As shown, the elastic sheet 20 includes a first segment 21, a second segment 22, and a third segment 23, which are bent sequentially. A second sub-limiting part is disposed on the first segment 21, a fourth sub-limiting part is disposed on the second segment 22, and the third segment 23 is used to press the cable 40. This arrangement, with the second sub-limiting part on the first segment 21 and the fourth sub-limiting part on the second segment 22, allows the elastic sheet 20 to be precisely controlled by the second limiting components from the first plate 13 and / or the third plate 15 during expansion and contraction. Simultaneously, the limiting effect of the first segment 21 and the second segment 22 ensures that the deformation of the elastic sheet during the pressing process remains within a predetermined safe range, preventing structural failure due to excessive deformation, ensuring the accuracy of the elastic sheet's reset each time, and enhancing the stability and reliability of the entire pressing structure.

[0040] In this embodiment, the third segment 23 is designed to directly compress the cable 40. Through the bending of the first segment 21 and the second segment 22, the third segment 23 can acquire sufficient elastic potential energy to quickly and forcefully compress the cable when the user operates the adjustment structure 31, achieving an efficient and stable electrical connection. When it is necessary to release the cable, the elastic sheet 20 can quickly return to its original shape by reversing the operation of the adjustment structure 31, allowing the third segment 23 to separate from the cable, simplifying the cable disassembly process and improving the user's operating experience and efficiency.

[0041] Specifically, the bending structure design of the elastic sheet 20, especially the first, second, and third segments that are connected and bent sequentially, can make full use of the three-dimensional space within the mounting bracket 10, enabling the elastic sheet to achieve complex movement paths and functions within a limited space. This not only helps reduce the overall size of the socket but also ensures that the various limiting and wire-pressing functions of the elastic sheet are effectively realized in a compact layout, demonstrating the ingenuity of the design and the optimization of the space layout.

[0042] like Figure 1 As shown, the first plate 13 includes a support plate segment 131, and a second segment 22 covers the support plate segment 131 away from the first plate surface, the first side edge, and at least part of the second plate surface of the third plate 15. Thus, by covering the support plate segment 131 with the second segment 22, especially the first plate surface, the first side edge, and at least part of the second plate surface, the mechanical strength of these parts can be significantly improved. The enhanced structure can better resist external physical impacts or stress concentration during operation, ensuring the stability and durability of the elastic sheet 20 when clamping and releasing cables, maintaining good performance and a long service life even under harsh operating conditions.

[0043] In this embodiment, the tight wrapping of the second segment 22 with the support plate segment 131 not only enhances the strength of the connection at the mechanical level but also optimizes the contact quality at the electrical level. This design helps reduce interruptions or attenuation in electrical signal transmission caused by poor contact, ensuring a stable connection between the cable 40 and the internal circuitry of the socket. This significantly improves the reliability of electrical contact, guaranteeing the normal operation of the equipment and the accurate transmission of data.

[0044] like Figure 2 and Figure 3 As shown, this application also provides a socket, including a socket wire clamping structure 50, a male plastic body 60, and a plastic sleeve 70. The male plastic body 60 covers a portion of the socket wire clamping structure 50, and the plastic sleeve 70 is fitted onto the male plastic body 60 to cover another portion of the socket wire clamping structure 50; wherein, the socket wire clamping structure 50 is the aforementioned socket wire clamping structure.

[0045] Specifically, the male connector's plastic body 60 and plastic sleeve 70 work together to provide protection against external environmental factors such as dust and moisture, and also to enhance the mechanical protection of the socket's wire clamping structure 50. The male connector's plastic body covers a portion of the wire clamping structure, while the plastic sleeve further covers the remaining portion. This double-covering method effectively prevents external impacts or wear from affecting the wire clamping structure, extending the socket's lifespan. Simultaneously, the segmented coverage of the socket's wire clamping structure 50 by the male connector's plastic body 60 and plastic sleeve 70 ensures a clear division of the operating area. Users can directly access designated operating parts on the male connector's plastic body (such as the wire clamping button), avoiding direct contact with live or delicate wire clamping structures, significantly reducing safety hazards during operation.

[0046] like Figure 2 and Figure 3 As shown, the mounting bracket 10 of the socket wire clamping structure 50 has a through hole. The socket also includes a crown spring terminal 80, which has a stepped surface. The crown spring terminal 80 passes through the through hole so that the stepped surface and the mounting bracket 10 form a limiting stop. In this way, the stepped surface of the crown spring terminal 80 and the edge of the through hole of the mounting bracket 10 form a limiting stop. The above structural design can ensure the precise positioning of the crown spring terminal inside the socket and also ensure the stability and reliability of the electrical connection.

[0047] like Figure 2 and Figure 3As shown, the socket also includes a female plastic body 90. The female plastic body 90 is fitted over the crown spring terminal 80. This fitting of the female plastic body 90 over the conductive crown spring terminal 80 effectively enhances the electrical safety of the socket, preventing users from accidentally contacting live metal parts and reducing the risk of electric shock. Simultaneously, the plastic material has excellent insulation properties, effectively isolating the crown spring terminal from direct contact with other metal parts or humid environments, reducing the possibility of short circuits or other electrical faults, and improving the overall safety of the socket.

[0048] In this embodiment, the female connector's plastic body not only provides electrical isolation but also serves as physical protection for the crown spring terminals. The plastic body absorbs external impacts, reducing direct damage to the crown spring terminals and extending their service life. When the socket is subjected to pressure or drops, the female connector's plastic body acts as a buffer layer, preventing deformation or displacement of the crown spring terminals, thereby ensuring the stability of the socket's internal structure and the continued effectiveness of its wire clamping function.

[0049] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0050] At least a portion of the elastic tab extends into the mounting cavity, enabling it to compress the cable inserted into the cavity using its inherent elasticity without external force. This allows cable connections to be completed manually without additional tools, thus solving the problem of cable fixing methods in related technologies requiring external tools and affecting wiring efficiency. When cable removal is needed, the elastic tab is pushed apart from the cable by adjusting the adjustment structure in component 30, again without the need for external tools, greatly simplifying the complexity of wiring operations and improving wiring efficiency. Simultaneously, the limiting part cooperates with the elastic tab to ensure the stability of the elastic tab's position when compressing the cable, preventing displacement of the elastic tab under prolonged use or slight external vibrations. This ensures the stability and reliability of the cable-socket connection, helps prevent accidental loosening of the cable during connection, and enhances the overall structural safety.

[0051] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
