Description

Technical Field

[0001] This invention relates to the field of electrical connection technology, and more particularly to an electrical connection component. Background Technology

[0002] Electrical connectors, also known as plugs, sockets, or terminals, are crucial basic components in modern electronic engineering technology. Their core function is to establish a reliable physical and electrical bridge between blocked or isolated circuits, enabling the stable flow of current or signals and ensuring the entire system performs its intended function.

[0003] Plug-in electrical connections typically consist of contacts (the core components for electrical conduction), insulators (ensuring insulation between the base and the contact surface), a housing (providing mechanical protection and alignment), and various auxiliary connection and locking mechanisms. With the rapid development of modern electronic equipment, new energy and energy storage systems, industrial automation, and smart communication base stations, the application scenarios for electrical connections are becoming increasingly complex and demanding. Modern industry not only requires electrical connection devices to have extremely low contact resistance and excellent conductivity, but also sets extremely high standards for their mechanical plug-in lifespan, smoothness of connection, shock resistance, and space utilization. Especially in assembly within confined spaces, operation in external environments, and conditions requiring frequent plug-in / plug-out changes, the mechanical and physical design of plug-in electrical connections often directly determines the safety boundaries and operational reliability of the entire system.

[0004] Electrical connectors and interconnects are key components for achieving electrical connectivity in modern lighting systems, especially modular luminaires. With the rise of the linear lighting and creative lighting market, connecting multiple luminaire units (such as linear lights and geometric mosaic lights) in series or in a matrix has become the mainstream approach.

[0005] Most existing connectors have strict polarity restrictions. Traditional connectors typically use a "foolproof" housing design to prevent incorrect insertion. While this design avoids reverse polarity, it forces users to carefully visually identify the mating direction before plugging or unplugging. In dim lighting, obstructed vision, or extremely confined spaces, it is difficult for operators to align the connector on the first try, making efficient one-handed blind insertion impossible and resulting in a very low error tolerance.

[0006] Furthermore, traditional modular lighting fixtures typically require external screws, metal connecting plates, or specialized locking clips to physically secure the two light units during electrical connection. This not only makes the installation process extremely cumbersome and increases labor costs, but also prevents the entire lighting module from achieving stable electrical conduction if the external fasteners are lost or damaged. Summary of the Invention

[0007] This application provides an electrical connection component to solve at least one of the above-mentioned problems in the prior art, and adopts the following technical solution: An electrical connection assembly includes: an electrical connection plug having at least two sets of electrical contact surfaces symmetrically arranged along the center of the electrical connection plug, and a guide portion at the end of the electrical connection plug guiding the insertion direction of the electrical connection plug; an elastic reset module cooperating with the electrical connection plug, the elastic reset module providing axial and radial elastic reset forces to the electrical connection plug to maintain the electrical connection plug in a preset position; and a driving member connected to the electrical connection plug and driving the electrical connection plug to move axially.

[0008] Preferably, the elastic reset module includes: an elastic support mechanism located at the end of the electrical connector away from the guide portion, the elastic support mechanism providing axial elastic reset force for the electrical connector; and a centering reset mechanism symmetrically arranged on both sides of the electrical connector. When the electrical connector is deflected by an external force, the centering reset mechanism is driven by the electrical connector to undergo elastic deformation. After the external force is released, the centering reset mechanism resets the electrical connector to the centered position.

[0009] Preferably, the centering reset mechanism includes a baffle and a first reset spring, the first reset spring being connected to the baffle, and the baffle being in contact with the side wall of the electrical connection plug.

[0010] Preferably, the electrical connection plug is slidably fitted with a sliding sleeve, which is located between the guide portion and the baffle. The baffle cooperates with the sliding sleeve to unlock and disengage the plugged guide portion.

[0011] Preferably, the sliding sleeve is provided with guide slopes, which are located at both ends of the axial direction.

[0012] Preferably, it further includes: a housing, in which the electrical connection plug and the elastic support mechanism are both housed; a limiting protrusion is provided on the side of the baffle, and a sliding groove matching the limiting protrusion is provided inside the housing.

[0013] Preferably, the outer wall of the housing is provided with hooks and hanging grooves to realize the assembly and connection between multiple housings.

[0014] Preferably, the housing has a drive groove, the drive member passes through the drive groove and is fixedly connected to the electrical connection plug, and the drive groove allows the drive member to move axially and radially along the electrical connection plug.

[0015] Preferably, it further includes: soft rubber blocks, which are symmetrically arranged on both sides of the electrical connection plug.

[0016] Preferably, the electrical connector has a T-shaped structure, the guide portion is located at the top of the T-shape, the guide portion is arc-shaped, and a slot is provided at the connection between the guide portion and the electrical connector, with the electrical contact surface located within the slot.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This electrical connection assembly sets the electrical connection plug into a T-shaped structure and arranges at least two sets of electrical connection contact surfaces symmetrically along the center. This allows the electrical connection structure to achieve perfect physical engagement and electrical conduction even when rotated 180 degrees in both directions. This breaks the "foolproof" limitation of traditional connectors that require identification of the front and back sides. It enables users to perform blind insertion with one hand even in dimly lit or confined spaces with obstructed vision, greatly improving the convenience of operation and docking efficiency.

[0018] 2. This electrical connection assembly achieves perfect decoupling of axial and radial forces on the connector by setting up independent elastic support mechanisms and centering and resetting mechanisms. The elastic support mechanism is specifically responsible for axial tensioning and resetting, while the centering and resetting mechanism is specifically responsible for radial offset avoidance and centering correction. This structure avoids the problem of fatigue failure caused by stress when using a single resetting structure, ensuring both flexible avoidance at the moment of docking and multi-dimensional tight locking when the connector is in place, significantly extending the service life of the mechanism.

[0019] 3. The electrical connection assembly is equipped with a sliding sleeve with a bidirectional guide ramp, which cooperates with the baffle. During the disconnection process, the bidirectional guide ramp provides a smooth obstacle-crossing trajectory for the opposing guide part, and the unlocking process is completed through the cooperation of the opposing guide part and the sliding sleeve.

[0020] 4. The electrical connection assembly, by adding symmetrical soft rubber blocks inside the housing, forms a flexible abutment clamp for the electrical connection plug after insertion. This not only effectively absorbs the impact energy under external vibration, but also eliminates loose noise between components and effectively prevents accidental detachment. Furthermore, the hook and hanging groove structure set on the outside of the housing further prevents accidental detachment. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] An embodiment of the present invention provides an electrical connection component. Example:

[0028] like Figure 3 and Figure 6 As shown: An electrical connection assembly includes an electrical connection plug 1, which has at least two sets of electrical contact surfaces 102, symmetrically arranged around the center of the electrical connection plug 1. For example, when there are two sets of electrical contact surfaces 102, they can be arranged symmetrically vertically or horizontally around the center of the electrical connection plug 1; for example, when there are four sets of electrical contact surfaces 102, one set is symmetrically arranged vertically around the center of the electrical connection plug 1, and the other set is symmetrically arranged horizontally around the center of the electrical connection plug 1. The connecting lines of the electrical contact surfaces 102 extend from the interior of the electrical connection plug 1 to the tail of the electrical connection plug 1. This centrally symmetrical layout breaks the mistaken-proof limitations of traditional connectors, allowing users to perform 180-degree blind insertion in dimly lit or narrow environments with obstructed vision without having to identify the front and back, greatly improving the convenience and fault tolerance of operation, and enabling free insertion of identical electrical connection components. The electrical connector 1 has a guide portion 101 at its end, which guides the insertion direction of the electrical connector 1; an elastic reset module, which cooperates with the electrical connector 1 and provides axial and radial elastic reset force to the electrical connector 1 to keep the electrical connector 1 in a preset position; and a drive member 2, which is connected to the electrical connector 1 and drives the electrical connector 1 to move axially.

[0029] like Figure 4-5 As shown: The elastic reset module includes: an elastic support mechanism 3, located at the end of the electrical connector 1 furthest from the guide portion 101, providing axial elastic reset force for the electrical connector 1; and a centering reset mechanism 4, symmetrically arranged on both sides of the electrical connector 1. When the electrical connector 1 is displaced by an external force, the centering reset mechanism 4 is driven by the electrical connector 1 to undergo elastic deformation. After the external force is released, the centering reset mechanism 4 resets the electrical connector 1 to the centered position. The axial reset and radial reset functions are independently handled by the elastic support mechanism 3 and the centering reset mechanism 4, respectively, effectively decoupling the forces during insertion and removal. This separate design perfectly balances the smoothness during insertion with the locking stability after connection, avoiding fatigue failure caused by the complex force of a single spring.

[0030] The centering reset mechanism 4 includes a baffle 401 and a first reset spring 402. The first reset spring 402 is connected to the baffle 401, and the baffle 401 is in contact with the side wall of the electrical connection plug 1.

[0031] A sliding sleeve 5 is slidably mounted on the electrical connector 1. The sliding sleeve 5 is located between the guide portion 101 and the baffle 401. The baffle 401 cooperates with the sliding sleeve 5 to unlock and disengage the guide portion 101 from the insertion point. Specifically, the sliding sleeve 5 and the baffle 401 can be non-magnetic. In this case, the sliding sleeve 5 and the baffle 401 are in a state of relative free movement along the axial direction. In this non-magnetic configuration, when performing a disconnection operation, the guide portion 101 of the opposing connector first contacts the guide ramp 501 at the front end of the sliding sleeve 5. Since the sliding sleeve 5 is in a free state, the thrust directly pushes the sliding sleeve 5 to generate an axial sliding stroke on the electrical connection connector 1 until the sliding sleeve 5 moves to abut against the baffle 401 (or is stopped by its own guide portion 101 during the retraction process) and cannot move further. As the opposing guide portion 101 continues to advance, the opposing guide portion 101 is constrained by the limiting stop of the sliding sleeve 5 and is forced to radially slide and expand along the guide ramp 501, thus completely overcoming the structural limitations to complete the unlocking. This free sliding design not only greatly simplifies the internal structure and reduces production costs, but also uses this free sliding idle stroke as a mechanical buffer, making the initial insertion and removal feel smoother and lighter. As a preferred embodiment, the sliding sleeve 5 and the baffle 401 can also be optionally configured as magnetically attracted sliding sleeve 5 and baffle 401, with the baffle 401 and the sliding sleeve 5 kept relatively fixed by magnetic attraction. Using magnetic attraction instead of traditional rigid mechanical snap-fit ​​connection ensures precise synchronous linkage between the baffle 401 and the sliding sleeve 5 during normal operation; furthermore, in the event of unexpected extreme lateral tensile forces, the magnetic structure allows for safe misalignment and sliding, thus providing overload protection and preventing breakage of internal rigid components.

[0032] The sliding sleeve 5 is provided with guide ramps 501, which are located at both ends of the axial direction. When the insertion and connection are released and the sliding sleeve 5 is magnetically fixed to the baffle 401: the guide ramp 501 located at the end near its own guide portion 101 (i.e., the front end) is used to contact the guide portion 101 of the opposite insertion piece, and to guide the opposite guide portion 101 to slide radially along the ramp and smoothly transition to the guide ramp 501 at the end away from the guide portion 101 (i.e., the rear end); while the guide ramp 501 located at the end away from the guide portion 101 (i.e., the rear end) is used to be hooked by the opposite guide portion 101 and move along with it during the backward retraction process, until the sliding sleeve 5 is abutted and limited by its own guide portion 101; subsequently, the guide ramp 501 at the rear end provides a ramp surface for the opposite guide portion 101 to slide and expand again, thereby completely releasing the latching and abutting between the two insertion piece guide portions 101. This bidirectional inclined surface design significantly reduces the instantaneous sliding friction resistance during end-face collisions, effectively preventing mechanism jamming and ensuring smooth disengagement. The frictional force between the guide part 101 and the guide inclined surface 501 is greater than the magnetic force between the sliding sleeve 5 and the baffle 401. This effectively prevents the guide part 101 from moving from the guide inclined surface 501 at the rear end of the sliding sleeve 5 to the guide inclined surface 501 at the front end due to insufficient friction when the guide part 101 moves the sliding sleeve 5. Otherwise, it would be unable to move the sliding sleeve 5.

[0033] like Figure 1-2 and Figure 7-8 As shown: It also includes: a housing 6, an electrical connection connector 1, and an elastic support mechanism 3, all housed within the housing 6; a limiting protrusion 411 protrudes from the side of the baffle 401, and a sliding groove 601 matching the limiting protrusion 411 is formed inside the housing 6. The guiding cooperation between the limiting protrusion 411 and the sliding groove 601 strictly restricts the baffle 401 to translate only along a set radial trajectory, preventing it from deflecting or flipping when subjected to spring force or magnetic attraction, thus ensuring the accurate transmission of the centering and resetting force.

[0034] The outer wall of the housing 6 is provided with hooks 602 and hanging grooves 603 to enable the assembly and connection between multiple housings 6. This modular assembly design allows the invention to be flexibly combined according to actual needs. This not only expands the application scenarios but also significantly reduces mold opening and manufacturing costs.

[0035] The housing 6 has a drive groove 604. The drive component 2 passes through the drive groove 604 and is fixedly connected to the electrical connection plug 1. The drive groove 604 allows the drive component 2 to move axially and radially along the electrical connection plug 1.

[0036] The housing 6 is also provided with a sliding groove 605 for the sliding sleeve 5 to slide. Specifically, the sliding groove 605 provides clearance and guidance space for the sliding sleeve 5 during axial sliding, effectively avoiding direct contact or large-area friction interference between the outer wall of the sliding sleeve 5 and the inner surface of the housing 6. This not only significantly reduces the sliding friction resistance when the sliding sleeve 5 moves, but also eliminates jamming caused by assembly tolerances, force deflection, or foreign object entry, significantly reduces component wear caused by long-term high-frequency insertion and removal, and ensures extremely smooth unlocking action and long service life of the structure.

[0037] It also includes: soft rubber blocks 7, which are symmetrically arranged on both sides of the electrical connection connector 1. The soft rubber blocks 7 not only absorb vibration energy when the structure is subjected to severe impact, but also compensate for machining tolerances after insertion, providing flexible contact support. Furthermore, during the insertion of the two electrical connection connectors 1, the soft rubber blocks 7 undergo slight deformation to support the insertion space required for the two electrical connection connectors 1. This effectively eliminates loosening and abnormal noise between components, improving the reliability of the electrical connection under vibration.

[0038] The electrical connector 1 has a T-shaped structure, with a guide portion 101 located at the top of the T. The guide portion 101 is arc-shaped, and a slot is provided at the connection between the guide portion 101 and the electrical connector 1. The electrical contact surface 102 is located within the slot. The T-shaped structure and the cooperation between the guide portion 101 and the slot form an anti-disengagement geometry. At the same time, concealing the electrical contact surface 102 within the slot effectively prevents accidental contact by fingers or scratches by foreign objects during insertion and removal, significantly improving electrical safety and the service life of the contact surface.

[0039] When two electrical connection devices equipped with the electrical connection components of this invention are plugged into each other: First, the driving members 2 of both devices are pushed to extend the guide portions 101 of their respective electrical connection plugs 1 outward from the cavity of the housing 6. Then, the two electrical connection plugs 1 are brought closer together; when the arcuate surfaces of the two guide portions 101 come into contact and press, the radial movement gap reserved in the driving groove forces the two electrical connection plugs 1 to radially avoid a misalignment. As they continue to advance towards each other, the two guide portions 101 pass over each other; at this point, the slotted corners where the two electrical connection plugs 1 connect to the guide portions 101 engage and abut against each other, and the electrical contact surfaces 102 of both devices achieve contact and conduction, completing the electrical connection. Finally, the driving member 2 is released to disengage the drive, and the elastic support mechanism 3 provides axial tension, causing the electrical connection plugs 1 to tend to retract and reset towards the interior of the housing 6, thereby tightening both devices; simultaneously, the centering and resetting mechanism 4 applies a radial resetting force to the deflected electrical connection plugs 1, causing them to tend towards centering, thus tightly locking the plugged state. After the connection is completed, the guide parts 101 of both parties partially penetrate into the housing 6 of the other party. At this time, the soft rubber block 7 inside the housing 6 forms a flexible support and limit on the electrical connection plug 1, effectively preventing the two electrical connection plugs 1 from being rigidly damaged or accidentally detached due to external vibration or pulling.

[0040] After the electrical connection is completed, the hook 602 is used to hang it into the slot 603 of the other party to achieve further connection and tightening, and to further prevent accidental detachment due to external vibration or pulling.

[0041] When two electrical connection devices equipped with the electrical connection components of this invention need to be disconnected: First, the driving member 2 actively pushes the electrical connection connectors 1 of both devices in the mating direction. The guide portions 101 of both devices will touch the guide slope 501 of the front end of the other device's sliding sleeve 5 (near its own guide portion 101). Since the other device's sliding sleeve 5 and the baffle 401 are kept relatively fixed by magnetic attraction, this pushing force causes the guide portion 101 to slide radially along the front guide slope 501 and move to the guide slope 501 at the rear end of the sliding sleeve 5. At this time, the electrical connection contact surfaces 102 of the two devices are initially separated. Subsequently, the driving member 2 is pulled in the opposite direction to retract the electrical connection connector 1 towards its own housing 6. During the retraction process, the guide portion 101 of the electrical connection connector 1 will hook the other device's sliding sleeve 5 and move together until the sliding sleeve 5 is stopped and abutted by the other device's own guide portion 101. At this point, continue to pull the drive component 2 backward, forcing the guide portion 101 of the electrical connection plug 1 to radially slide and expand along the guide slope 501 at the rear end of the other party, completely overcoming the structural constraints of the other party, releasing the fastening, and completing the physical separation of the two.
