[0001] This utility model relates to the technical field of instruments, and more specifically, to the connection structure between an instrument and a data cable. Background Technology

[0002] With the continuous development of society and the continuous progress of technology, electric bicycles have become one of the most commonly used means of transportation in people's daily travel. Electric bicycles are an improved means of transportation based on ordinary bicycles, equipped with motors, batteries, control systems, instruments, and operating components. Among them, the instrument of the electric bicycle is used to display various data. The instrument is electrically connected to the controller and the button head through data cables. In this way, the controller can be controlled by pressing the buttons on the button head, and the controller and other parameters can be displayed on the instrument. It is one of the essential accessories of electric bicycles.

[0003] Most existing electric bicycle gauges are integrated structures, with the data cable directly soldered to the circuit board inside the gauge. This means that during the manufacturing and assembly of the gauge, it is necessary to wait for the data cable to be matched and then solder the data cable to the circuit board inside the gauge before the gauge can be assembled, which greatly reduces the manufacturing and assembly efficiency of the gauge. Utility Model Content

[0004] The purpose of this invention is to provide a connection structure between an instrument and a data cable, aiming to solve the problem of low manufacturing and assembly efficiency of instruments in the prior art.

[0009] Furthermore, a sealing ring is protruding on the inner wall of the annular stepped groove, and the sealing ring is arranged circumferentially around the inner wall of the annular stepped groove. A sealing groove that mates with the sealing ring is opened on the side of the annular plug head.

[0010] When the annular plug is fully inserted into the annular stepped groove, the sealing ring and the sealing groove form a circumferential compression seal.

[0011] Furthermore, external screw holes are respectively provided on both sides of the end, and an installation platform is provided on the instrument housing. The installation platform is arranged circumferentially around the external opening of the plug cavity. Two internal screw holes are provided on the installation platform, and the two internal screw holes are respectively located on both sides of the plug cavity. The end is connected to the installation platform by screws passing through the external screw holes and the internal screw holes.

[0012] Furthermore, a limiting protrusion is provided on the mounting platform, and when the end is installed on the mounting platform, one side of the end abuts against the limiting protrusion.

[0016] Furthermore, the mounting platform has a locking piece protruding on each side, the locking piece being located in the limiting area, and one side of the locking piece engaging with the limiting protrusion; the bottom of the end is concave inward to form a locking groove that matches the shape of the locking piece.

[0017] Furthermore, the instrument housing is equipped with a display, which is electrically connected to the circuit board.

[0018] Compared with existing technologies, the instrument and data cable connection structure provided by this utility model enables quick connection and disconnection of the data cable and the instrument through a plug-in structure, eliminating the need for soldering or complex wiring.

[0030] Reference Figure 1-7 The image shown is a preferred embodiment of the present invention.

[0031] The instrument and data cable 20 connection structure includes an instrument housing 10, a circuit board disposed within the instrument housing 10, and a data cable 20. The data cable 20 and the instrument housing 10 are connected by a plug-in connection. The side wall of the instrument housing 10 has a plug-in cavity 11, and the bottom of the plug-in cavity 11 has a conductive spring contact that is in communication with the circuit board. One end of the data cable 20 is electrically connected to a controller or a button, and the other end of the data cable 20 has a terminal 21, on which a plug 22 is provided, and conductive contacts are embedded in the plug 22.

[0032] When the data cable 20 is inserted into the plug cavity 11 through the plug 22, the conductive contacts are electrically connected to the conductive spring, thereby realizing the electrical connection between the data cable 20 and the circuit board.

[0033] The instrument and data cable 20 connection structure provided above enables quick connection and disconnection of the data cable 20 and the instrument through a plug-in structure, eliminating the need for soldering or complex wiring. This facilitates installation, replacement, or maintenance, and improves the assembly efficiency of the instrument. The elastic contact design of the conductive spring and contacts ensures the stability of signal transmission and reduces the risk of poor contact. The plug-in cavity 11 is integrated into the side wall of the instrument housing 10, saving internal space and making it suitable for compact instrument equipment. This solves the problem of low manufacturing and assembly efficiency of the instrument.

[0034] Data cable 20 can be a shielded data cable 20.

[0035] In this embodiment, the upper part of the insertion cavity 11 is expanded outward to form an annular stepped groove 12, and the upper part of the plug 22 is provided with an annular plug head 23 that matches the shape of the annular stepped groove 12.

[0036] When the data cable 20 is inserted into the plug cavity 11 through the plug 22, the bottom of the annular plug 23 abuts against the bottom of the annular stepped groove 12, and the outer periphery of the annular plug 23 abuts against the inner wall of the annular stepped groove 12.

[0037] The annular stepped groove 12 and the annular plug head 23 cooperate to guide the insertion direction of the plug 22 and avoid misalignment or displacement. The contact surface between the annular plug head 23 and the annular stepped groove 12 provides multi-point support, disperses insertion and extraction stress, and extends the service life of the plug structure. The annular surface contact increases the friction between the plug 22 and the plug cavity 11, preventing the data cable 20 from falling off due to vibration or external force.

[0038] In this embodiment, a sealing ring 13 is protruding on the inner wall of the annular stepped groove 12. The sealing ring 13 is arranged around the inner wall of the annular stepped groove 12 in a circumferential manner. A sealing groove 24 that cooperates with the sealing ring 13 is opened on the side of the annular plug head 23.

[0039] When the annular inserter 23 is fully inserted into the annular stepped groove 12, the sealing ring 13 and the sealing groove 24 form a circumferential compression seal.

[0040] The compression seal between the sealing ring 13 and the sealing groove 24 prevents external moisture and dust from entering the insertion cavity 11, making it suitable for outdoor or harsh environments; the sealing structure protects the conductive spring and conductive contacts from corrosion, ensuring the reliability of long-term electrical connection.

[0041] In this embodiment, external screw holes 25 are respectively provided on both sides of the end 21, and an installation platform 30 is provided on the instrument housing 10. The installation platform 30 is arranged around the external opening of the insertion cavity 11. Two internal screw holes 31 are provided on the installation platform 30. The two internal screw holes 31 are respectively located on both sides of the insertion cavity 11. The end 21 is connected to the installation platform 30 by screws passing through the external screw holes 25 and the internal screw holes 31.

[0042] The screw connection provides additional physical fixation to prevent the plug 22 from shaking or loosening due to external forces; the screw hole design allows for quick disassembly and assembly, facilitating data cable 20 replacement or instrument maintenance.

[0043] In this embodiment, a limiting protrusion 40 is provided on the mounting platform 30. When the end 21 is installed on the mounting platform 30, one side of the end 21 abuts against the limiting protrusion 40.

[0044] The limiting protrusion 40 constrains the position of the end 21 to prevent the plug 22 from rotating and shifting when the screw is tightened; the abutment limiting simplifies the assembly steps and improves installation efficiency.

[0045] In this embodiment, the instrument housing 10 is provided with a horizontal fastener 50 for connecting with the vehicle pole, and one end of the horizontal fastener 50 is rotatably connected to the limiting protrusion 40.

[0046] The horizontal fastener 50 can be directly fastened to external structures such as the vehicle frame, expanding the installation scenarios for the instrument (such as bicycles and electric vehicles); the swivel connection design allows for fastener angle adjustment to adapt to different installation position requirements.

[0047] In this embodiment, the horizontal fastener 50 includes a connecting strip 51 and a fastening strip 52 that surrounds the connecting strip 51 to form a fastening cavity 53. One end of the fastening strip 52 is hinged to one end of the connecting strip 51, and the other end of the fastening strip 52 is connected to the connecting strip 51 by a screw. The other end of the connecting strip 51 is rotatably connected to the limiting protrusion 40.

[0048] The adjustable size of the locking cavity 53 adapts to rods of different diameters, enhancing versatility; the hinged locking strip 52 simplifies installation, allowing for fastening with a single screw, thus improving efficiency.

[0049] In this embodiment, when two limiting protrusions 40 are provided on the installation platform 30, the two limiting protrusions 40 are spaced apart to form a limiting area. The limiting area is located above the insertion cavity 11 and the two are interconnected. Horizontal fasteners 50 are respectively connected to the two limiting protrusions 40.

[0050] The double limiting protrusions 40 and double fastener design enhance the connection strength between the instrument and the external structure, making it suitable for high vibration environments. The limiting area provides routing space for the data cable 20, preventing excessive bending of the cable and internal breakage, and ensuring that the end 21 is centered during insertion.

[0051] Two horizontal fasteners 50 are symmetrically installed on both sides of the instrument housing 10.

[0052] In this embodiment, the mounting platform 30 has a locking piece 32 protruding on both sides. The locking piece 32 is located in the limiting area, and one side of the locking piece 32 is connected to the limiting protrusion 40. The bottom of the end 21 is concave inward to form a locking groove 211 that matches the shape of the locking piece 32.

[0053] The interlocking design of the locking piece 32 and the locking groove 211 enhances the mechanical locking force between the end 21 and the mounting platform 30; it prevents the end 21 from accidentally falling off when the screws loosen, and improves the safety of the connection redundancy.

[0054] In this embodiment, a display 60 is provided on the instrument housing 10, and the display 60 is electrically connected to the circuit board.

[0055] The display 60 provides real-time feedback on data transmitted by the circuit board (such as vehicle speed and battery level), enhancing the user's interactive experience. The display 60 and the circuit board are integrated into the same housing, reducing the need for external cables and optimizing the device's appearance.

[0056] This utility model solves the problems of easy loosening, complex assembly, and poor environmental adaptability of traditional instrument data cables by using plug-in connection, sealed protection, multi-level limiting, and modular snap-fit ​​design. Its core advantages include:

[0057] 1. High reliability: The elastic contact between the conductive spring and the contact point, the sealing ring 13 and the screw fixation form a triple protection to ensure stable electrical connection.

[0058] 2. Quick installation: The design of the plug-in guide, limiting protrusion 40 and locking groove 211 simplifies the assembly steps and lowers the operation threshold.

[0059] 3. Environmental adaptability: Waterproof, dustproof, and vibration-resistant properties meet the requirements of harsh scenarios such as automotive and industrial applications.

[0060] 4. Scalability: The horizontal fastener 50 and display 60 modules support functional expansion to adapt to diverse application scenarios.

[0061] This patented technology can be widely used in fields such as vehicle instruments and industrial control equipment, and has significant market application value.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
