Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a magnetic connector and its application. Background Technology

[0002] Existing male and female plugs typically consist of two parts: a plug and a socket. The protruding part on the plug is designed to insert into the recessed area of ​​the socket. Typical structures include DC male and female connectors and power plugs. However, existing male and female plugs lack a quick-locking function upon insertion, hindering flexible and rapid plugging and unplugging. Furthermore, the protruding part on existing plugs is mostly exposed when not in use, and the recessed area remains. In addition, how to achieve automatic locking of small connectors within a limited space is a technical problem that needs to be solved. Summary of the Invention

[0003] In order to solve the problems mentioned in the background art, the present invention aims to provide a magnetic connector and its application.

[0004] The present invention adopts the following technical solution.

[0005] A magnetic connector includes an upper connector and a lower connector with built-in magnets. The upper connector has a protruding male head inside, and the lower connector has a female head inside. When the bottom surface of the upper connector contacts or approaches the top surface of the lower connector, the male head hidden inside the upper connector immediately extends under the magnetic attraction and enters the insertion hole of the lower connector and is locked.

[0006] To facilitate the insertion and removal of the magnetic connectors, before the male connector extends, the lower end face of the male connector and the bottom face of the upper connector are on the same plane, and the top face of the lower connector and the top face of the female connector are also on the same plane.

[0007] Furthermore, the magnetic connector of the present invention also includes a locking structure disposed on the sides of the male and female heads, wherein the latch of the locking structure is laterally deflected and limited to achieve locking.

[0008] To achieve a more flexible quick-lock mechanism for magnetic connectors, the locking structure of this invention includes: a fixed column and a rotatable latch. The column is inserted into a slot at the base of the latch. In the initial state, the latch rests against the side edge of the male connector. As the male connector extends and moves to its limit position, the latch deflects laterally and locks itself between the limiting platform and the side edge of the male connector, thus achieving a lock. In this invention, the initial state refers to the state when the male connector of the magnetic quick-lock plug is not extended.

[0009] To reduce the space occupied by the latch in the initial state, a groove is provided on the side edge of the male end, and the latch head in the initial state fits into the groove; a spring is provided on the top of the latch, and the spring is used to pre-compress the latch so that the latch head in the initial state fits into the groove.

[0010] To improve the stability of the magnetic connector in the locked state, in the initial state, the latch is obliquely abutted against the side edge of the male connector, and the groove in this state is higher than the limiting platform; in the locked state, the latch is vertically locked between the limiting platform and the side edge of the male connector, and the groove in this state is lower than the limiting platform; the latch head is crescent-shaped, with the concave side of the latch head facing outward; the limiting platform is set on the housing of the female connector; or, the edge of the insertion hole on the housing of the female connector is used as the limiting platform.

[0011] To improve the safety of the magnetic connector, the present invention further includes a female head locking structure. The female head locking structure includes a step on the female head, a movable magnet assembly 1 is provided on the side of the step, a wedge-shaped part is provided on one side of the magnet assembly, a latch is provided next to the wedge-shaped part, a return spring 2 is connected to the tail of the latch, and a V-shaped groove that matches the wedge-shaped part is provided on the latch. Before the male and female heads are magnetically attracted, the latch rests against the step to keep the female head locked. During the magnetic attraction between the male and female heads, the magnet assembly 1 moves upward and drives the latch to disengage from the step to release the lock on the female head. After the male and female heads are separated, the latch is reset under the action of the return spring 2 and rests against the step.

[0012] To reduce the difficulty and travel of unlocking the magnetic connector, the magnetic connector of the present invention also includes a male unlocking mechanism disposed on the upper connector. The male unlocking mechanism includes a button and a movable part. One end of the movable part is connected to the button, and the other end of the movable part is connected to a reset spring. The movable part is connected to the male trigger part. When the button is pressed, the movable part moves laterally, thereby pushing the male trigger part upward. During this process, the male trigger part moves upward synchronously with the male connector. After the button is released, the movable part resets under the action of the reset spring.

[0013] Furthermore, the male connector is also connected to a male connector reset spring, which is used to drive the male connector to reset after the magnetic attraction between the male connector and the female connector is disconnected.

[0014] To enable more flexible and quick insertion and removal of the magnetic connector, a second magnet is installed inside the male connector, which is directly opposite the first magnet assembly. A third magnet is installed inside the female connector. When the bottom surface of the upper connector contacts or approaches the top surface of the lower connector, the second magnet and the first magnet assembly are magnetically attracted, which drives the first magnet assembly to move towards the male connector to unlock the female connector. Subsequently, the female connector and the second magnet are magnetically attracted, causing the male connector to move towards the female connector and make contact with it.

[0015] This invention also provides the application of magnetic connectors in electrically conductive components: In one application, an electrical spring is provided inside the lower connector. When the male and female connectors are connected, the electrical spring presses against the conductive part of the male connector to enable the male and female connectors to be energized. When the male and female connectors are separated, the electrical spring detaches from the male connector to de-energize. or, In another application, an electrical spring is provided inside the upper connector. When the male and female connectors are connected, the electrical spring presses against the conductive part on the side wall of the female connector to enable the male and female connectors to be energized. When the male and female connectors are separated, the electrical spring detaches from the female connector to de-energize.

[0016] To improve the flexibility and safety of magnetic connectors in energized components, an electric spring is connected to an actuating element, which is rotatably mounted on a shaft. The shaft is mounted on the housing of a male or female connector, and the arc-shaped convex surface of the electric spring is used to abut against conductive components.

[0017] This invention also provides the application of magnetic connectors in pluggable components, which are electronic products and their connectors / sockets, lighting equipment and their connectors / sockets, external products and their connectors / sockets, and mechanical equipment connectors and their connectors / sockets; wherein, electronic products include but are not limited to power banks, tablet computers, computers, and display terminals; lighting equipment includes but is not limited to table lamps, hanging lamps, and flashlights; external products include but are not limited to car humidifiers, tabletops, car toys, and car ornaments; and mechanical equipment connectors include but are not limited to power tool connectors and robot connectors.

[0018] Beneficial effects: The magnetic connector provided by this invention is small in size, not only allowing both the male and female heads to be completely hidden inside the housing / connector when not connected, but also enabling quick locking and automatic locking of the male head after insertion within a limited space. It can only be unlocked and inserted when the male and female heads are close to each other, avoiding the risk of accidental electric shock, and the locked connector has good stability. The magnetic connector provided by this invention has the advantages of flexibility, efficiency, and quick insertion and removal, allowing anyone to achieve quick connection and blind insertion, making operation very convenient. The magnetic connector provided by this invention has a short unlocking stroke, eliminating the need to overcome the full magnetic force when unlocking with a button, enabling easy and quick unlocking. In particular, it enables rapid and automatic locking and energization of two fully planar electrically conductive components when docked. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. In the present invention, directional terms such as "upper" and "lower" are defined based on the state when the upper connecting member 1 is above and the lower connecting member 2 is below, that is, based on... Figure 1 , Figure 12 , Figure 13 The direction defined by the shown state.

[0021] Example 1: Combination Figures 1 to 15 As shown, a magnetic connector includes an upper connector 1 and a lower connector 2, both containing built-in magnets. The upper connector 1 has a protruding male head 11, which, in conjunction with a limiting member 27, is installed within an upper housing 16 to allow vertical movement only. The lower connector 2 has a vertically movable female head 21. When the bottom surface 12 of the upper connector 1 contacts or approaches the top surface 20 of the lower connector 2, the male head 11, hidden inside the upper connector 1, immediately extends under magnetic attraction and is locked into the insertion hole of the lower connector 2. Before the male head 11 extends, its lower end face is on the same plane as the bottom surface 12 of the upper connector 1, and the top surface 20 of the lower connector 2 is also on the same plane as the top surface of the female head 21.

[0022] In this embodiment, combined with Figure 4 , Figure 6 , Figure 12 and Figure 13 As shown, the magnetic connector also includes a locking structure located on the sides of the male connector 11 and the female connector 21. Two sets of locking structures are symmetrically arranged. The locking latch 13 of the locking structure is laterally deflected and limited to achieve locking. Each locking structure includes: a column 15 fixedly mounted on the male connector 11, and a rotatable latch 13. The column 15 is inserted into the waist hole 14 at the base of the latch 13. Initially, the latch 13 rests against the side edge of the male connector 11. As the male connector 11 extends and moves down to its limit position, the latch 13 laterally deflects and locks between the limiting platform 38 and the side edge of the male connector 11 to achieve locking. Figure 12 and Figure 13 The diagram corresponds to the states of the latch 13 before and after lateral deflection. The male connector 11 has a groove 9 along its side edge, and the head of the latch 13 initially fits into this groove. A spring 30 is located on the top of the latch 13, which pre-presses the latch 13 to ensure its initial engagement with the groove 9. In the initial state, the latch 13 is angled against the side edge of the male connector 11, and the groove 9 is higher than the limiting platform 38. In the locked state, the latch 13 is vertically locked between the limiting platform 38 and the side edge of the male connector 11, and the groove 9 is lower than the limiting platform 38. The head of the latch 13 is crescent-shaped, with its concave side facing outwards. The limiting platform 38 is the edge of the insertion hole on the housing 22 of the female connector 21, which is also the outer shell of the lower connector 2. This specific locking structure also ensures smooth extension / retraction of the male connector.

[0023] In this embodiment, as Figures 5 to 10As shown, the magnetic connector also includes a female locking structure. The female locking structure includes a step 34 on the female connector 21. A magnetic assembly 28 capable of vertical movement is provided on the side of the step 34. A wedge-shaped portion 26 is provided on the edge of the magnetic assembly 28. A latch 32 is provided next to the wedge-shaped portion 26. A return spring 33 is connected to the tail of the latch 32. A V-shaped groove 36 that engages with the wedge-shaped portion 26 is provided on the latch 32. Before the male connector 11 and the female connector 21 are magnetically attracted, the latch 32 abuts (or rests) against (or adheres to) the step 34 to lock the female connector 21. At this time, the female connector 21 is limited and cannot move away from the male connector 11. The wedge-shaped portion 26 engages in the V-shaped groove 36 (combined with...). Figure 6 and Figure 15 (Illustrative image); During the magnetic attraction between the male connector 11 and the female connector 21, the magnet assembly 28 moves upward (essentially, the magnet assembly 28 moves towards the male connector 11) and drives the latch 32 to disengage from the step 34, thereby releasing the lock on the female connector 21. After the male connector 11 and the female connector 21 separate, the latch 32 is reset by the return spring 33, causing the latch 32 to abut against the step 34. The principle behind the upward movement of the magnet assembly 28 driving the latch 32 to disengage from the step 34 is as follows: the magnet assembly 28 transmits force to the wall of the V-groove 36 through the wedge-shaped part 26, and the wedge-shaped part 26 then laterally presses the latch 32 and the return spring 33 through the wall of the V-groove 36, thereby causing the latch 32 to disengage from the step 34.

[0024] In this embodiment, as Figures 7 to 10 As shown, the magnetic connector also includes a male unlocking mechanism disposed on the upper connector 1. The male unlocking mechanism includes a button 10 and a movable member 8. One end of the movable member 8 is connected to the button 10, and the other end of the movable member 8 is connected to a reset spring 6 via a spring mounting head 5. The movable member 8 is connected to a male trigger part 7, which is provided with a first inclined surface 4. The movable member 8 and the button 10 are respectively provided with second inclined surfaces 29, which can cooperate to abut against the first inclined surface 4. When the magnetic connector is connected, the button is not pressed. At 10 o'clock, the first inclined surface 4 of the male trigger part 7 is against the second inclined surface 29; when the button 10 is pressed, the button 10 drives the movable part 8 to move laterally, thereby pushing the male trigger part 7 upward. During this process, the male trigger part 7 and the male head 11 move upward synchronously until the first inclined surface 4 and the second inclined surface 29 are completely misaligned and separated (at this time, the male head 11 has moved up a certain distance relative to the female head 21, and the upward movement (the height of the first inclined surface 4) can be controlled at 1~1.5mm). After the button 10 is released, the movable part 8 is reset under the action of the reset spring 6.

[0025] In this embodiment, the male connector 11 is also connected to a male connector reset spring, which is used to drive the male connector 11 to reset after the male connector 11 is magnetically disconnected from the female connector 21. The male connector reset spring can be installed at the bottom of the male connector 11 or at the top of the male connector 11, as long as it is an optional position that can drive the male connector 11 to reset.

[0026] In this embodiment, the magnetic attraction process is as follows: [The text abruptly ends here, likely due to an incomplete sentence or Figure 15 As shown, a second magnet 37 is provided on the male connector 11, which is directly facing the first magnet assembly 28. A third magnet 35 is provided inside the female connector 21. When the bottom surface of the upper connector 1 contacts or approaches the top surface of the lower connector 2, the second magnet 37 and the first magnet assembly 28 are magnetically attracted, thereby driving the first magnet assembly 28 to move in the direction of the male connector 11 to unlock the female connector 21. Subsequently, the female connector 21 and the second magnet 37 are magnetically attracted, causing the male connector 11 to move in the direction of the female connector 21 and contact the female connector 21.

[0027] The main working principle of the magnetic connector in this embodiment is as follows.

[0028] Locking structure: In the initial state, the slightly compressed spring 30 presses down on the latch 13, causing the head of the latch 13 to engage in the groove 9. At this time, the top of the waist hole 14 abuts against the column 15, and the outer side of the head of the latch 13 just abuts against the edge of the male inlet / outlet hole of the upper housing 16 (the state at this time is as follows). Figure 12 (As shown); When the bottom surface of the male connector 11's housing contacts the top surface of the female connector 21's housing 22, the male connector 11 is attracted by the magnetic force of the female connector 21 and immediately extends and enters the insertion hole. During this process, the male connector 11 will press down on the female connector 21. As the male connector 11 moves down, it will also move the latch 13 down a certain distance. When the head 24 of the latch 13 just begins to engage between the limiting platform 38 and the side edge of the male connector 11, it will stop moving down. As the male connector 11 continues to move down, the inclined surface of the groove 9 of the male connector 11 will laterally press the head 24 of the latch 13 until the head 24 is completely upside down on the limiting platform 38 (at this time, the latch 13 is vertically engaged between the limiting platform 38 and the side edge of the male connector 11, the bottom of the waist hole 14 abuts against the column 15, and the male connector 11 is restricted from moving down further. The spring 30 is in a compressed state). This achieves the locking of the male connector 11 and the female connector 21. The state at this time is as follows. Figure 13 As shown; after the male connector 11 and the female connector 21 are separated, the male connector 11 can be reset by means of a reset spring.

[0029] Female connector locking mechanism: Before the male connector 11 and female connector 21 are magnetically attracted, the latch 32 abuts against the step 34 to keep the female connector 21 locked (e.g., Figure 9 and Figure 10As shown), the second return spring 33 is in a free state; during the magnetic attraction between the male head 11 and the female head 21, the first magnet assembly 28 moves upward and drives the latch 32 to disengage from the step 34 to release the lock on the female head 21 (the state at this time is as shown). Figure 7 and Figure 8 As shown), during this process, the second return spring 33 is in a compressed state, and the female head 21 can move up and down, thereby achieving the magnetic attraction between the male head 11 and the female head 21; when the male head 11 and the female head 21 are separated, the latch 32 is reset under the action of the second return spring 33, so that the latch 32 abuts against the step 34.

[0030] Male connector unlocking mechanism: When button 10 is pressed, button 10 drives the movable part 8 to move laterally, thereby pushing the male connector trigger part 7 upward. During this process, the male connector trigger part 7 and male connector 11 move upward synchronously. At this time, male connector 11 is raised a certain distance relative to the top surface of female connector 21. During the raising of male connector 11, the arc-shaped convex surface of the head 24 of latch 13 loses its limit, and the head 24 of latch 13 will return to the groove 9. Spring 30 can also assist the head 24 of latch 13 to return to the groove 9 to a certain extent. Then the operator can easily separate male connector 11 from female connector 21, that is, separate upper connecting part 1 from lower connecting part 2. After releasing button 10, movable part 8 is reset under the action of reset spring 6.

[0031] In this embodiment, the male head 11 can be inserted into the female head's socket the instant the male head 11 contacts the female head 21 (that is, the upper connector 1 contacts the lower connector 2), and the locking of the male head 11 and the female head 21 is completed simultaneously. It can also be flexibly locked quickly, and the stability after locking is good. In the non-connected state, the protruding parts (male head 11, female head 21) can be completely hidden inside the housing of the male head 11.

[0032] In this embodiment, the magnetic connector is used in the DC power supply component (or energized component) in the first application scheme, combined with... Figures 14 to 16 As shown in the diagram, for ease of illustration, the lower connector 2 is positioned above the upper connector 1 (as is normally the case). Figure 1 The lower connector 2 shown should be below the upper connector 1. In this solution, combined with Figure 4As shown, the outer shell of the upper connector 1 is the upper shell 16 of the male connector 11, and the outer shell of the lower connector 2 is the shell 22 (i.e., the lower shell) of the female connector 21. The male connector 11 is installed inside the rectangular upper shell 16. The bottom wall of the upper shell 16 is provided with a male connector inlet / outlet hole (i.e., the bottom surface of the male connector 11 is provided with a male connector inlet / outlet hole). In the initial state (the male connector 11 does not extend out of the male connector inlet / outlet hole, for example, when the male connector 11 is far away from the female connector 21), the female connector 21 is installed inside the rectangular lower shell. In the initial state, the top surface 20 of the shell 22 of the female connector 21 is provided with an insertion hole. When the bottom surface of the shell of the male connector 11 contacts the top surface of the shell 22 of the female connector 21, the male connector 11 is attracted by the magnetic force of the female connector 21 and immediately extends out and enters the insertion hole, and is locked by the locking structure at the same time. An electrical spring 3 is provided inside the lower connector 2. One end of the electrical spring 3 is flat and the other end is curved. The electrical spring 3 is connected to the actuating element 39, which is rotatably sleeved on the shaft 25. The shaft 25 is mounted on the housing 22 of the female connector 21. The curved convex surface (curved outer wall) of the electrical spring 3 is used to abut against the conductive component. Before the male connector 11 and the female connector 21 are magnetically attracted, the electrical spring 3 abuts against the insulating area of ​​the female connector 21. After the male connector 11 and the female connector 21 are magnetically connected, the male connector 11 will extend into the insertion hole of the lower connector 2, and the electrical spring 3 will press against the conductive component on the side wall of the male connector 11 to realize the energization of the male connector 11 and the female connector 21 (the state at this time is as follows). Figure 16 As shown), after the male connector 11 separates from the female connector 21, the electrical spring 3 abuts against the insulating area of ​​the female connector 21 (the state at this time is as shown). Figure 17 (As shown in the image), at this point the power is cut off.

[0033] In this embodiment, the magnetic connector is used in the second application scheme of the DC power supply component. An electrical spring is provided inside the upper connector 1. When the male connector 11 is connected to the female connector 21, the electrical spring abuts against the conductive part on the side wall of the female connector 21 to realize the power supply between the male connector 11 and the female connector 21. When the male connector 11 is separated from the female connector 21, the electrical spring abuts against the insulating area of ​​the male connector 11, and the power is cut off at this time.

[0034] The magnetic connector in this embodiment is small in size, allowing both the male and female heads to be completely hidden inside the housing / connector when not connected. It also enables quick locking and automatic locking of the male head after insertion within a limited space. Unlocking and insertion only occur when the male and female heads are close to each other, avoiding the risk of accidental electric shock. The locked connector also exhibits good stability. Furthermore, it offers advantages of flexibility, efficiency, and rapid insertion / removal, allowing anyone to achieve quick connection and blind insertion. It can achieve quick connection, blind insertion, and smooth unlocking even in extremely small height spaces (e.g., spaces with a height 10mm greater than the total thickness of the magnetic connector), making operation very convenient. It also features a short unlocking stroke; even an unlocking stroke of less than 5mm is sufficient for usage requirements. Unlocking by button does not require overcoming the full magnetic force, allowing for easy and quick unlocking. In particular, it enables rapid and automatic locking and energization of two fully planar DC power supply components when connected.

[0036] Example 3 is a magnetic connector similar to Example 1, but the difference between Example 1 and Example 3 is that the male unlocking mechanism is omitted.
