Description

Technical Field

[0001] This invention relates to the field of electrical connection technology, and more specifically to a magnetically attached electrical connector. Background Technology

[0002] With the development of smart buildings and smart homes, electrically controlled photochromic glass doors, capable of switching between transparent and opaque states according to usage needs, are widely used in office spaces, commercial venues, and public buildings. In practical applications, electrically controlled photochromic glass doors typically consist of a main door glass and side door glass, requiring the transmission of electrical signals or power between them so that the side door glass can synchronously switch between transparent and opaque states with the main door glass. In existing technologies, the power supply to the main door glass and side door glass mainly relies on pre-embedded wires in the door frame or wall, with the power supply to the main door being led out and connected to the side door glass through grooved wiring. This method has the following problems during construction: firstly, the wiring construction is complex, the construction period is long, and installation costs are increased; secondly, grooved wiring can be somewhat destructive to the building structure and decorative effect, and maintenance and replacement are also inconvenient.

[0003] Therefore, how to achieve a reliable and controllable electrical connection between the main door glass and the side door glass without relying on complex wiring construction has become a technical problem that needs to be solved in this field. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a magnetically attached electrical connector. By installing it on the main door frame, it engages with metal or magnetic components on the side door frame. When the main door is closed, the conductive spring in the connector automatically extends under magnetic force and contacts the metal or magnetic components on the side door, thereby enabling the transmission of electrical signals between the main door and the side door.

[0005] To achieve the above objectives, the following technical solution is adopted: a magnetically attached power connector, comprising a housing body, a contact circuit board, two magnetic conductive springs, two conductive pressure caps, and two telescopic springs. The housing body includes an outer shell, an outer shell end panel, and two mounting bases. The two mounting bases are located inside the outer shell and are adapted to conductive spring posts. The mounting openings of the two mounting bases are located on the outer shell end panel. The bottom of the outer shell is hollowed out, and the hollowed-out area is adapted to contact the circuit board. The contact circuit board is used for wiring and power supply to an external controller, and the contact circuit board is assembled at the bottom of the housing. The two conductive springs are respectively assembled in two mounting bases, ensuring that the head of the conductive spring can extend out of the outer shell end panel. The tail ends of the two conductive springs are respectively fixedly connected to two pressure caps, forming a conductive path between the conductive springs and the pressure caps. The telescopic spring has two connector ends pre-drilled at both ends of its spring wire. These two connector ends serve as the first and second wiring pins, respectively. The two telescopic springs are respectively fitted onto the two conductive spring posts. One end ring of the telescopic spring acts on the mounting base, and the other end ring acts on the pressure cap. In its natural state, the telescopic spring ensures that the head end face of the conductive spring post is on the same plane as the end panel of the outer shell. The first terminals of the two telescopic springs are fixedly connected to their corresponding pressure caps, forming a conductive path between each telescopic spring and the pressure cap. The second terminals of the two telescopic springs are soldered to the contact circuit board, and the two second terminals are connected to the positive and negative terminals of the contact circuit board, respectively, forming a conductive path between each telescopic spring and the contact circuit board.

[0006] Furthermore, two detection springs are respectively provided on the surface of the contact circuit board, and a silicone protective sleeve is provided on the contact circuit board. The silicone protective sleeve is located between the detection springs and the pressure cover. This ensures that when the telescopic spring is in its natural state, the pressure cover squeezes the detection springs through the silicone protective sleeve, so that the two detection springs are respectively connected to the on / off detection circuits of the positive and negative terminals of the contact circuit board. When the telescopic spring is in the compressed state, the pressure cover separates from the silicone protective sleeve, so that the two detection springs are respectively disconnected from the on / off detection circuits of the positive and negative terminals of the contact circuit board.

[0007] Furthermore, the conductive spring includes a spring housing, a conductive spring, a magnetic block, and a metal contact cover. One end of the spring wire of the conductive spring is reserved as a conductive lead. The conductive spring and the magnetic block are placed in the mounting groove inside the spring housing. One end of the conductive spring acts on the magnetic block, and the other end acts on the bottom of the mounting groove inside the spring housing. The conductive lead of the conductive spring passes through the spring housing and is fixedly connected to the pressure cover, so that the conductive spring and the pressure cover form a conductive path. The mounting groove of the conductive spring is provided with a metal contact cover, and the magnetic block is connected to the metal contact cover under the action of the conductive spring.

[0008] Furthermore, the pressure cap includes a spring-loaded fixing cap and a conductive circuit board. The conductive circuit board is installed inside the spring-loaded fixing cap. The spring-loaded fixing cap and the conductive circuit board are installed at the bottom of the spring-loaded housing by pressure cap fixing screws. The conductive terminals of the conductive spring are soldered to the conductive circuit board.

[0009] Furthermore, the outer casing is also equipped with contact circuit board screw posts and contact circuit board positioning posts. The contact circuit board is mounted on the contact circuit board positioning posts and fixed to the contact circuit board screw posts by circuit board fixing screws.

[0010] Furthermore, the outer wall of the outer casing is also provided with casing fixing buckles for fixing the casing body into the mounting groove of the door frame.

[0011] The beneficial effects of this invention are as follows: The magnetic connector of this invention achieves a reliable and automatic electrical connection between the main door and the side door glass through a reasonable combination of conductive springs, telescopic springs, pressure caps, and a contact circuit board. This compact structure can be directly installed on the main door without the need for slotting and wiring, simplifying construction and facilitating later maintenance. The conductive springs automatically contact the metal or magnetic components of the side door under magnetic force, achieving a stable and reliable electrical connection and ensuring synchronized electrical control operation of the main door and the side door glass. Simultaneously, the detection spring on the contact circuit board can detect the current path status between the conductive springs and the contact circuit board, thereby preventing safety issues when a current path is not formed.

[0014] Example 1 The following description, in conjunction with the accompanying drawings, further illustrates the points, such as... Figure 1-7 The magnetic connector shown includes a housing body 1, a contact circuit board 2, two magnetic conductive springs 3, two conductive pressure caps 4, and two telescopic springs 5, wherein... Regarding the design of the housing body 1, such as Figure 8 As shown, the housing body 1 includes an outer shell 100, an outer shell end panel 101, and two mounting bases 102. The two mounting bases 102 are located inside the outer shell and are adapted to conductive spring posts. The mounting openings of the two mounting bases 102 are located on the outer shell end panel 101. The bottom of the outer shell is hollowed out, and the hollowed-out area is adapted to the contact circuit board 2. The outer shell 100 also has contact circuit board screw posts 103 and contact circuit board positioning posts 104. The outer wall of the outer shell 100 is also provided with a housing fixing buckle 105 for fixing the housing body 1 in the mounting groove of the door frame. The contact circuit board 2 is designed to be a circuit board with electrical signal transmission function that can be connected to the power supply box and controller. The contact circuit board 2 includes at least a continuity detection circuit. Two detection springs 200 are respectively provided on the surface of the contact circuit board 2, and a silicone protective sleeve 6 is provided on the contact circuit board 2. When the two detection springs 200 are closed, they are connected to the continuity detection circuits at the positive and negative terminals of the contact circuit board 2, respectively. When the two detection springs 200 are released, they are disconnected from the continuity detection circuits at the positive and negative terminals of the contact circuit board 2, respectively. The conductive spring 3 is designed to include a spring housing 300, a conductive spring 301, a magnetic block 302, and a metal contact cover 303. The conductive spring 301 and the magnetic block 302 are placed in a mounting groove inside the spring housing 300. One end of the conductive spring 301 acts on the magnetic block 302, and the other end acts on the bottom of the mounting groove inside the spring housing 300. The metal contact cover 303 is installed at the opening of the mounting groove of the conductive spring 301, serving as the head of the conductive spring 3. The bottom of the spring housing 300 serves as the tail of the conductive spring 3. The magnetic block 302 connects to the metal contact cover 303 under the action of the conductive spring 301. One end of the spring wire of the conductive spring 301 is reserved as a conductive terminal 3010. The design of the pressure cap 4 includes a spring-loaded fixing cover 400 and a conductive circuit board 401, with the conductive circuit board 401 installed inside the spring-loaded fixing cover 400. For the design of the telescopic spring 5, two connector ends are reserved at both ends of the spring wire of the telescopic spring 5. The two connector ends serve as the first terminal 500 and the second terminal 501, respectively. The specific assembly structure of the present invention is as follows. The contact circuit board 2 is mounted on the contact circuit board positioning post 104 and is fixed by the circuit board fixing screw 7 and the contact circuit board screw post 103, so that it is assembled at the bottom of the housing 100 for wiring and power supply with an external controller. The shells 300 of the two conductive springs 3 are respectively assembled in the two mounting bases 102, ensuring that the metal contact covers 303 of the conductive springs 3 can extend out of the outer end panel 101. The spring fixing cover 400 and the conductive circuit board 401 are installed at the bottom of the spring shell 300 by the cover fixing screws 8, so that the conductive springs 3 and the cover 4 form a fixed whole. The conductive terminals 3010 of the conductive spring 301 pass through the spring shell 300 and the spring fixing cover 400 and are welded to the conductive circuit board 401, so that a conductive path is formed between the metal contact cover 303, the magnetic block 302, the conductive spring 301 and the conductive circuit board 401. Two telescopic springs 5 ​​are respectively fitted onto two conductive spring posts 3. One end ring of the telescopic spring 5 acts on the mounting base 102, and the other end ring acts on the spring post fixing cover 400 of the pressure cover 4. In its natural state, the telescopic spring 5 ensures that the end face of the metal contact cover 303 of the conductive spring post 3 is on the same plane as the end panel 101 of the outer shell. The first terminal 500 of the two telescopic springs 5 ​​is fixedly connected to their corresponding pressure covers 4. Specifically, the first terminal 500 passes through the spring post fixing cover 400 and is soldered to the conductive circuit board 401, so that a conductive path is formed between the telescopic spring 5 and the conductive circuit board 401. The second terminal 501 of the two telescopic springs 5 ​​both pass through silicone protective films. The protective sleeve 6 is connected to the positive and negative terminals of the contact circuit board 2, respectively, so that each telescopic spring 5 forms a passage between the contact circuit board 2 and the contact circuit board 2. The silicone protective sleeve 6 is located between the detection spring 200 and the pressure cover 4, ensuring that when the telescopic spring 5 is in its natural state, the pressure cover 4 squeezes the detection spring 200 through the silicone protective sleeve 6, so that the two detection springs 200 are respectively connected to the on / off detection circuit of the positive and negative terminals of the contact circuit board 2. When the telescopic spring 5 is in the compressed state, the pressure cover 4 separates from the silicone protective sleeve 6, so that the two detection springs 200 are respectively disconnected from the on / off detection circuit of the positive and negative terminals of the contact circuit board 2.

[0015] This invention is installed on the main door frame and works in conjunction with metal or magnetic components on the side door frames. After installation, the contact circuit board 2 is electrically connected to the power supply box of the glass and the controller. Under the control of the electronic control system, the contact circuit board 2 is powered by the power supply box, and the controller controls the power supply box's on / off state. When the main door and side door are not closed, the metal or magnetic components on the side door frame and the invention installed on the main door frame are not connected. At this time, the telescopic spring 5 is in its natural state, the end face of the metal contact cover 303 of the conductive spring post 3 is flush with the outer casing end panel 101, and the head of the conductive spring post 3 is still within the mounting base 102. At this time, the pressure cover 4 squeezes the detection spring 200 through the silicone protective sleeve 6, so that the two detection springs 200 are in a closed connection with the on / off detection circuit of the positive and negative terminals of the contact circuit board 2, feeding back the detected electrical signal to the controller. Under the control of the electronic control system, the controller sends a control signal to the power supply box to cut off the power. This is to prevent accidental electric shock. When the main door and side door are closed, under the magnetic force of the metal or magnetic components on the side door frame, the head of the conductive spring 3 extends from the assembly port of the mounting base 102 and establishes a connection with the metal or magnetic components on the side door frame. Since the pressure cover 4 and the conductive spring 3 are fixedly connected, when the head of the conductive spring 3 pops out, the pressure cover 4 moves with the conductive spring 3. At this time, the telescopic spring 5 is in a compressed state, the pressure cover 4 separates from the silicone protective sleeve 6, and the two detection springs 200 are disconnected from the on / off detection circuit of the positive and negative terminals of the contact circuit board 2. The detected electrical signal is fed back to the controller. Under the control of the electronic control system, the controller sends a control signal to the power supply box to implement power supply processing. The contact circuit board 2 is powered by the power supply box of the glass. The current flows from the positive terminal of the contact circuit board 2 to the metal on the side door frame according to the conductive path of the present invention, and finally returns to the negative terminal of the contact circuit board 2 through the circuit inside the glass of the side door, forming a current path, thereby realizing the transmission of electrical signals between the main door and the side door.
