Description

Technical Field

[0001] This utility model relates to the field of traffic safety facilities, and in particular to a conductive connector and a solar delineator. Background Technology

[0002] Road delineators, as crucial road traffic safety facilities, are used to indicate road boundaries and warn of obstacles, playing a key role in guiding vehicles and pedestrians safely at night or in low-visibility environments. Traditional delineators mostly employ passive reflective principles, relying on vehicle headlights or external light sources for warning, which suffers from limitations such as limited light reflection efficiency, short visibility distance, and poor environmental adaptability. With the development of intelligent transportation technology, actively luminous solar-powered delineators are gradually becoming mainstream. By integrating solar panels and a rechargeable power supply, they drive the luminous module to actively emit light, achieving all-weather warning without external power supply, significantly improving road safety and reliability.

[0003] However, existing solar delineators still have many technical bottlenecks in terms of power transmission efficiency, structural stability, and environmental adaptability. The traditional conductive connectors used between their solar panels and power sources mostly adopt a simple plug-in structure, which lacks precise positioning design. During docking, circumferential rotation or radial offset is prone to occur, resulting in poor contact between the spring pin and the contact point, increased contact resistance, and power loss. At the same time, rainwater and dust in complex outdoor environments can easily penetrate into the connector, causing oxidation and corrosion of the metal contacts, further aggravating the risk of contact failure.

[0004] Therefore, the purpose of this application is to provide a conductive connector that can reliably connect and stably transmit electrical energy, and the solar delineator applied thereto. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model proposes a conductive connector and a solar energy delineator to solve the above problems.

[0006] According to a first aspect of this application, a conductive connector is provided, including a female connector assembly and a male connector assembly. The female connector assembly includes a female connector housing and a first circuit board, and the male connector assembly includes a male connector housing and a second circuit board. A guide portion is provided on the side of the male connector housing, and the upper part of the female connector housing is sleeved on the lower part of the male connector housing via the guide portion. The first circuit board and the second circuit board are respectively embedded and fixed on the female connector housing and the male connector housing. The opposing surfaces of the first circuit board and the second circuit board are respectively provided with an equal number of spring pins and contacts, and the spring pins are electrically connected to the contacts.

[0007] By adopting the above technical solution, the female head shell and the male head shell can be quickly positioned when they are connected by the guide part. The embedded first circuit board and the second circuit board make the overall structure more compact and stable. The equal number of spring pins and contacts form an efficient conductive connection, which can reduce contact resistance and reduce losses. The above structure has modular characteristics, which facilitates disassembly and maintenance.

[0008] Preferably, the male and female head shells are arranged parallel to each other vertically and are both cylindrical and annular; the guide portion protrudes from the outer side of the male head shell and extends vertically, and the inner side of the female head shell is provided with a guide groove corresponding to the guide portion.

[0009] By adopting the above technical solution, the radial forces of the male and female head shells are balanced by the symmetrical and uniform ring design, which improves the torsional strength of the overall structure. The coaxial layout of the two is more space-saving and adaptable to the integration requirements of miniaturized equipment. The vertical guide part, together with the guide groove, ensures that the docking process only moves along the axial direction, avoiding axial rotation and offset.

[0010] Preferably, the male head housing includes a reference portion and a snap-fit ​​portion disposed at the top and bottom, the outer diameter of the snap-fit ​​portion is larger than the outer diameter of the reference portion, and the outer diameter of the connection between the reference portion and the snap-fit ​​portion has a stepped transition.

[0011] By adopting the above technical solution, the difference in outer diameter between the snap-fit ​​part and the reference part forms an axial limiting structure. When the female head shell is sleeved, the insertion depth can be accurately defined at the stepped transition point, avoiding structural damage or poor contact caused by over-insertion, while preventing detachment and significantly enhancing the stability of the connection.

[0012] In a further preferred embodiment, the top surface of the female head housing extends upward to form a snap fastener adapted to the size of the snap fastener, and the inner side of the snap fastener is provided with an inwardly protruding arc-shaped flange corresponding to the connection point.

[0013] By adopting the above technical solution, the size of the snap-fit ​​buckle and the snap-fit ​​part are matched, and its inner arc-shaped flange can be precisely engaged at the stepped transition between the base part and the snap-fit ​​part to form an axial elastic locking structure. On the one hand, the mechanical limit prevents the male and female heads from accidentally disengaging, significantly enhancing the anti-pull-out capability in the connected state. On the other hand, the flexible contact design of the arc-shaped flange can buffer the rigid collision during the insertion and removal process, reduce stress concentration, and improve the structural durability.

[0014] Even more preferably, the female head housing also has movable notches on both sides of the snap fastener.

[0015] By adopting the above technical solution, the movable notch provides space for the elastic deformation of the snap-fit. During insertion and removal, the snap-fit ​​can expand or contract appropriately to the outside, which greatly reduces the engagement resistance at the transition between the arc-shaped flange and the male housing step, and gives the snap-fit ​​flexible buffer characteristics. When the conductive connector is subjected to axial tensile force or vibration load, the snap-fit ​​can absorb part of the stress through elastic deformation, preventing fatigue cracks from occurring between the arc-shaped flange and the step surface due to rigid contact, and effectively extending the service life of the structure.

[0016] Preferably, the female head housing has a mounting partition in the middle, the mounting partition has a mounting groove adapted to the size of the first circuit board, and the mounting groove has an arc-shaped hole for the spring pin to pass through.

[0017] By adopting the above technical solution, the first circuit board is embedded in the mounting groove on the mounting partition, and the spring pin on the first circuit board passes through the arc-shaped hole and makes an electrical connection with the corresponding contact on the second circuit board, ensuring that the spring pin and the contact are accurately aligned during installation.

[0018] Preferably, the male connector housing has a mounting boss at its center, and the side of the mounting boss is connected to the male connector housing by a rib. The second circuit board has a mounting hole at its center that mates with the mounting boss.

[0019] By adopting the above technical solution, the mounting boss is connected to the housing through the side ribs to form a stable three-dimensional support structure. After the mounting hole in the center of the second circuit board is matched with the mounting boss, the axial positioning and radial limiting of the second circuit board are realized, ensuring that the contact and the spring pin always remain perpendicular and aligned.

[0020] Preferably, the edges of the first circuit board and the second circuit board are provided with positioning notches, and the inner sides of the female head shell and the male head shell are provided with positioning parts corresponding to the positioning notches.

[0021] By adopting the above technical solution, when installing the first circuit board / second circuit board, the positioning notch is aligned with the positioning part to achieve unique directional positioning during installation, avoiding misalignment of the spring pin and contact point due to rotation or offset, and forming a mechanical constraint to effectively suppress the shaking or displacement of the first circuit board / second circuit board in the female head housing / male head housing.

[0022] Preferably, the bottom surface of the male head housing is also provided with an annular sealing groove, and a sealing ring is embedded in the sealing groove.

[0023] By adopting the above technical solution, the sealing ring is embedded in the sealing groove. When the female head shell and the male head shell are fitted together, the sealing ring will fit tightly against the surface of the mounting plate, forming an efficient dustproof and waterproof barrier. This prevents the spring pin and contact from being oxidized, corroded or having poor contact due to contamination, and significantly improves the reliability of the conductive connector in harsh environments such as humid, dusty and highly polluted conditions.

[0024] According to a second aspect of this application, a solar delineator is proposed, including a conductive connector as described in any of the above claims, and also including a delineator body and a solar panel. The surface of the delineator body is provided with a light-emitting module, and the interior of the delineator body is provided with a main control module and a rechargeable power supply. The main control module is electrically connected to the rechargeable power supply and the light-emitting module, and the rechargeable power supply and the solar panel are respectively electrically connected to a first circuit board and a second circuit board through lines.

[0025] By adopting the above technical solution, a compact conductive connector is integrated into the solar delineator, ensuring low power loss in the transmission of electrical energy between the solar panel and the rechargeable power source. Furthermore, the main control module intelligently manages the working status of the light-emitting module, significantly reducing energy consumption, extending battery life, and reducing manual maintenance costs.

[0026] Compared with the prior art, the beneficial effects of this application are as follows:

[0027] The conductive connector proposed in this utility model uses a guide part and a guide groove to achieve fast and precise docking, avoiding circumferential rotation and radial offset. The stepped structure of the cylindrical annular male head shell, female head shell, and snap-fit ​​part enhances mechanical stability, prevents disengagement, and buffers stress. The embedded circuit board and positioning design ensure reliable conductivity between the spring pin and the contact point, reducing contact loss. The sealing groove and sealing ring form a dustproof and waterproof barrier, adapting to harsh environments such as humid and dusty conditions. After integrating this connector with the solar panel delineator, low-loss power transmission between the solar panel and the rechargeable power supply is achieved. The main control module intelligently manages the light-emitting module, reducing energy consumption, extending battery life, and reducing manual maintenance costs. Attached Figure Description

Detailed Implementation

[0036] In the following detailed description, reference is made to the accompanying drawings, which form part of the detailed description and illustrate illustrative specific embodiments in which the present invention may be practiced. In this regard, directional terms such as “top,” “bottom,” “left,” “right,” “up,” “down,” etc., are used with reference to the orientation of the described figures. Because components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present invention. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

[0037] According to the first aspect of this application, a conductive connector is proposed. Figure 1 An exploded view of the structure of a conductive connector according to an embodiment of this application is shown, as follows: Figure 1 As shown, the conductive connector includes a female connector assembly and a male connector assembly. The female connector assembly includes a female connector housing 01 and a first circuit board 03. The male connector assembly includes a male connector housing 02 and a second circuit board 04. A guide portion 05 is provided on the side of the male connector housing 02. The upper part of the female connector housing 01 is sleeved on the lower part of the male connector housing 02 via the guide portion 05. The first circuit board 03 and the second circuit board 04 are respectively embedded and fixed on the female connector housing 01 and the male connector housing 02. The opposing surfaces of the first circuit board 03 and the second circuit board 04 are respectively provided with an equal number of spring pins 06 and contacts 07. The spring pins 06 and the contacts 07 are electrically connected.

[0038] The female connector housing 01 achieves rapid positioning and docking with the male connector housing 02 through the guide part 05. The first circuit board 03 and the second circuit board 04 are respectively embedded in the female connector housing 01 and the male connector housing 02, making the structure after the conductive structure is assembled more compact and stable. The cooperation between the spring pin 06 and the contact 07 can form an efficient conductive connection. The conductive connector as a whole has modular characteristics, which is conducive to later disassembly and maintenance.

[0039] In specific applications, the spring pin 06 includes, but is not limited to, spring pins and elastic pins. When it comes into contact with the contact 07, it will generate elastic compression, making the contact between the two more complete and avoiding the contact break problem that may occur when using rigid pins. In some special application scenarios, ordinary rigid pins can also be used here.

[0040] Specifically, the male head housing 02 and the female head housing 01 are arranged parallel to each other vertically and are both cylindrical and annular; the guide part 05 is protruding on the outer side of the male head housing 02 and extends vertically; the bottom surface of the male head housing 02 is also provided with an annular sealing groove 08, and a sealing ring 09 is embedded in the sealing groove 08.

[0041] The sealing ring 09 is not completely embedded in the sealing groove 08. A part of it protrudes outside the sealing groove 08. When the male head housing 02 and the female head housing 01 are fully engaged, the part of the sealing ring 09 that protrudes outside the sealing groove 08 contacts the inside of the female head housing 01 and is subjected to pressure, thereby deforming and achieving a sealing effect.

[0042] Figure 2 A schematic diagram of the housing assembly according to a specific embodiment of this application is shown, such as... Figure 1-2 As shown, the male housing 02 includes a reference part 10 and a snap-fit ​​part 11 arranged vertically. The outer diameter of the snap-fit ​​part 11 is larger than the outer diameter of the reference part 10, and the outer diameter of the connection between the reference part 10 and the snap-fit ​​part 11 is stepped.

[0043] The outer diameter of the snap-fit ​​part 11 is larger than that of the base part 10, forming an axial limiting structure. When the female head housing 01 is fitted, the insertion depth can be accurately defined at the stepped transition.

[0044] Specifically, the inner side of the female head housing 01 is provided with a guide groove 12 corresponding to the guide part 05, and the top surface of the female head housing 01 extends upward with a snap fastener 13 adapted to the size of the snap fastener 11. The inner side of the snap fastener 13 is provided with an inwardly protruding arc-shaped flange 14 at the corresponding connection point.

[0045] In this embodiment, two snap-fit ​​parts 11 are symmetrically arranged, and the actual number is not limited. The guide groove 12 is opened on the inner side of one of the snap-fit ​​buckles 13. The guide part 05 is arranged on the outer side of the snap-fit ​​part 11 of the male head housing 02. The guide groove 12 can also be opened on the inner side of multiple snap-fit ​​buckles 13. Accordingly, the position and number of the guide part 05 can correspond to the snap-fit ​​buckle 13.

[0046] The arc-shaped flange 14 can be precisely engaged at the stepped transition between the base part 10 and the locking part 11 to form an axial elastic locking structure. On the one hand, it prevents the male and female heads from accidentally disengaging through mechanical limiting, significantly enhancing the anti-pull-out capability in the connected state. On the other hand, the flexible contact design of the arc-shaped flange 14 can buffer the rigid collision during the insertion and removal process, reducing stress concentration.

[0047] Furthermore, the female housing 01 also has movable notches 15 on both sides of the snap fastener 13.

[0048] The notch 15 increases the range of motion of the snap fastener 13 when it undergoes radial elastic deformation along the female housing 01, making it easier to attach the female housing 01 to the male housing 02.

[0049] Figure 3 A schematic diagram of a first circuit board mounting according to a specific embodiment of this application is shown, such as... Figure 1-3 As shown, the female head housing 01 has a mounting partition 16 in the middle, and the mounting partition 16 has a mounting groove 17 adapted to the size of the first circuit board 03, and the mounting groove 17 has an arc-shaped hole 18 for the spring pin 06 to pass through.

[0050] Specifically, the first circuit board 03 and the mounting groove 17 are also provided with corresponding holes, which can improve the fixing effect of the first circuit board 03 in conjunction with other fasteners. In this embodiment, there are four spring pins 06, and their distribution is adapted to the structure of the arc-shaped hole 18. The number and distribution of the contact points 07 are adapted to the spring pins 06.

[0051] Furthermore, the surface of the mounting partition 16 facing away from the first circuit board 03 is the back side. When the male head housing 02 and the female head housing 01 are fitted together, the part of the sealing ring 09 protruding from the sealing groove 08 is in contact with the back side of the mounting partition 16.

[0052] Figure 4 A schematic diagram of a second circuit board mounting according to a specific embodiment of this application is shown, such as... Figure 1-4 As shown, the male connector housing 02 has a mounting boss 19 at its center. The side of the mounting boss 19 is connected to the male connector housing 02 by a rib 20. The second circuit board 04 has a mounting hole 21 at its center that mates with the mounting boss 19.

[0053] Specifically, the ribs 20 are symmetrically arranged on both sides of the mounting boss 19 and are connected to the inner side of the male housing 02 to form a frame structure. When the second circuit board 04 is installed, the mounting hole 21 is aligned with the mounting boss 19, and the back of the second circuit board 04 is in contact with the surface of the ribs 20. At the same time, holes for reinforcement with other fasteners are also provided on the second circuit board 04 and the ribs 20.

[0054] Specifically, the edges of the first circuit board 03 and the second circuit board 04 are provided with positioning notches 22, and the inner sides of the female head housing 01 and the male head housing 02 are provided with positioning parts 23 corresponding to the positioning notches 22.

[0055] When installing the first circuit board 03 / second circuit board 04, the positioning notch 22 is aligned with the positioning part 23 to achieve a unique directional positioning during installation, avoiding misalignment of the spring pin 06 and the contact point 07 due to rotation or offset, and forming a mechanical constraint to effectively suppress the shaking or displacement of the first circuit board 03 / second circuit board 04 in the female head housing 01 / male head housing 02.

[0056] According to a second aspect of this application, a solar delineator is proposed, comprising a conductive connector as described in any of the preceding claims. Figure 5 An exploded view of the outline structure according to an embodiment of this application is shown. As shown, the outline also includes an outline body and a solar panel 24. The surface of the outline body is provided with a light-emitting module, and the interior of the outline body is provided with a main control module 25 and a rechargeable power supply 26. The main control module 25 is electrically connected to the rechargeable power supply 26 and the light-emitting module, and the rechargeable power supply 26 and the solar panel 24 are electrically connected to the first circuit board 03 and the second circuit board 04 respectively through lines.

[0057] Specifically, the delineator body includes a guardrail base 27 and a delineator housing 28. The guardrail base 27 is used in conjunction with the guardrails on both sides of the highway. The delineator housing 28 is detachably installed in the lower recess of the guardrail base 27. In specific application scenarios, the fixing methods of the delineator housing 28 include, but are not limited to, bolt fixing, plug-in (interference fit), etc.

[0058] In a specific embodiment, the main control module 25 is composed of functional modules such as a circuit board, MCU, storage module, and communication module, and can realize functions such as data transmission and remote control.

[0059] Furthermore, the light-emitting module consists of a reflector 29 and an LED light-emitting element 30, and the reflector 29 and the LED light-emitting element 30 are provided on both sides of the delineator housing 28. The reflector 29 is used for passive reflection, and the LED light-emitting element 30 works with the main control module 25 to achieve the function of intelligent active light-emitting warning.

[0060] Furthermore, the wiring used to connect the solar panel 24 to the second circuit board 04 on the male housing 02 can be partially hidden inside the guardrail base 27, or it can pass through the outline housing 28 from the back of the guardrail base 27. This partial hiding method can ensure the safety of the wiring.

[0061] The rechargeable power supply 26 includes, but is not limited to, a lithium battery. The rechargeable power supply 26 is connected to the first circuit board 03 on the female connector housing 01 via a line. The female connector housing 01 is connected to the male connector housing 02, which ultimately enables the circuit between the solar panel 24 and the rechargeable power supply 26, thereby supplying power to the main control module 25 and the LED light-emitting element 30.

[0062] By integrating a compact conductive connector into the solar delineator, low power loss is ensured in the power transmission between the solar panel 24 and the rechargeable power source 26. Furthermore, the main control module 25 intelligently manages the working status of the light-emitting module, significantly reducing energy consumption, extending battery life, and reducing manual maintenance costs.

[0063] The conductive connector of this application is not limited to use in the aforementioned solar delineators, but can be used in any device with a relatively compact structure, high requirements for connection reliability, and a need for stable power transmission.

[0064] It is obvious that those skilled in the art can make various modifications and changes to the embodiments of this utility model without departing from the spirit and scope of this utility model. In this way, this utility model is also intended to cover such modifications and changes if they fall within the scope of the claims of this utility model and their equivalents. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are described in mutually different dependent claims does not indicate that a combination of these measures cannot be used for profit. Any reference numerals in the claims should not be considered as limiting the scope.
