[0027] Embodiment 1:

[0028] like Figures 1 to 4 As shown, a magnetically controlled electric switch with a memory function includes a housing 1, a memory device and a display screen 2 arranged on the housing 1, a coil frame 3 is arranged in the housing 1, a coil 4 is wound on the coil frame 3, and a mounting channel 31 is arranged on the coil 4 along the axial direction, a reed switch 5 is arranged in the mounting channel 31, the coil 4 includes an electrical connection terminal, the reed switch 5 has a connected state and a disconnected state, and it realizes state switching under the action of the magnetic field of the coil 4. Compared with the traditional electromagnetic relay, it can not only greatly reduce the overall volume of the product and reduce the cost of the product, but also has the characteristics of simple structure, fast switching speed, and long contact electrical life. In addition, it is particularly suitable for the control of multi-channel circuits.

[0029] The memory device and the reed switch 5 are connected to the coil 4. The memory device includes a counting module and a timing module. The counting module is used to count the number of on and off times of the reed switch 5. The timing module is used to time the power-on time of the reed switch 5. The display screen 2 is used to display the count value and the timing value. This greatly improves the intelligence of the electric control switch, and also improves the maintenance efficiency of the electric control switch, and avoids additional losses caused by misjudgment of the cause of the fault. Among them, the specific structures of the counting module, the timing module and the display screen 2 can refer to the corresponding structures of the intelligent circuit breaker, the intelligent relay, etc. in the prior art.

[0030] Furthermore, there are at least two reed switches 5, and they are evenly distributed along the circumference of the installation channel 31. In this embodiment, four reed switches 5 are evenly arranged circumferentially in the installation channel 31, which can control four circuits at the same time. The reed switches 5 are evenly distributed, which ensures the consistency of the action of each reed switch 5, and also helps to reduce the impact of electromagnetic interference and improve electromagnetic compatibility.

[0031] A circuit frame 6 made of a PCB board is arranged outside the coil skeleton 3, and a connecting circuit is printed on it. The reed switch 5 includes a reed 51, and the reed 51 and the power connection end are both connected to the circuit frame 6. The circuit frame 6 extends downward to have a connecting end 9 corresponding to the reed 51 and the power connection end. The connecting end 9 is uniformly led out on one side through the circuit frame 6, which is more convenient when connected externally.

[0032] In this embodiment, the axial direction of the installation channel 31 is aligned with the height direction of the shell 1, that is, the reed switch 5 is also arranged along the height direction of the shell 1. In this way, the length and width dimensions can be reduced by increasing the height dimension of the product, which is suitable for some installation environments with sufficient longitudinal space but insufficient horizontal space.

[0033] The circuit frame 6 includes a top circuit board 61 arranged above the coil skeleton 3, side circuit boards 62 arranged on both sides of the coil skeleton 3, and a bottom circuit board 63 arranged below the coil skeleton 3.

The internal wiring of the product can be omitted, which is beneficial to the miniaturization of the relay, and it is more convenient to install functional modules on the circuit frame, which is beneficial to the realization of diversified product functions.

[0034] Furthermore, the traditional reed switch 5 has a normally open type, a normally closed type and a conversion type. In the present embodiment, the reed 51 includes a normally open contact, a normally closed contact and a common end contact. One of the normally open contact and the normally closed contact is connected to the top circuit board 61, and the other is connected to the bottom circuit board 63. The common end contact is connected to the top circuit board 61 or the bottom circuit board 63, and the power connection end is connected to the side circuit board 62. The reed switch 5 is directly fixed to the circuit frame 6 by the metal contact, which is not only conducive to the realization of automated assembly, but also can reduce the additional fixing bracket and reduce the cost of the product.

[0035] Furthermore, a rectifier bridge 7 is included. The rectifier bridge 7 is used to make the connection terminals of the reed switch 5 not need to distinguish polarity. The rectifier bridge 7 is arranged on the circuit frame 6. In the present embodiment, the rectifier bridge 7 is arranged on the side circuit board 62. Usually, it is only necessary to connect the rectifier bridge 7 in series in the loop. Of course, those skilled in the art can adjust the connection according to the actual loop. In this way, the wiring of the reed switch 5 is more convenient and the difficulty of wiring is reduced.

[0036] Furthermore, a coil power consumption reduction device is also included, and the coil power consumption reduction device includes a resistor 8 connected to the coil 4. Those skilled in the art can adapt the connection according to the actual circuit, generally using series voltage division. The coil power consumption reduction device is used to reduce the number of turns required for the coil 4, thereby further reducing the overall volume of the product. The resistor 8 is arranged on the circuit frame 6. In this embodiment, the resistor 8 and the power terminal are connected to the circuit board 62 on the same side.

[0037] Furthermore, the shell 1 includes a base 101 and an upper shell 102, the circuit frame 6 is fixed on the base 101, and a plurality of grooves 1011 are provided on the end surface of the base 101 facing the circuit frame 6. The shape of the grooves 1011 is designed according to the actual product adaptability. The grooves 1011 can not only prevent heat from accumulating on the bottom circuit board 63 and extend the service life of the electric control switch, but also reduce the material used in the base 101 and reduce the cost of the product.

[0038] Embodiment 2:

[0039] like Figure 5 and Figure 6 As shown, based on the first embodiment, the axial direction of the installation channel 31 described in this embodiment is aligned with the length or width direction of the shell 1, that is, the reed switch 5 is also arranged along the length or width direction of the shell 1. In this way, the height dimension can be reduced by increasing the horizontal dimension of the product, which is suitable for some installation environments with insufficient longitudinal space but sufficient horizontal space.

[0040] Furthermore, the circuit frame 6 includes a first circuit board 64 disposed on both sides of the coil skeleton 3 and a second circuit board 65 disposed below the coil skeleton 3 , and one circuit board can be reduced compared to the first embodiment.

[0041] Furthermore, the reed switch 51 includes a normally open contact, a normally closed contact and a common end contact, the normally open contact and the common end contact are connected to the first circuit board 64 on the same side, and the normally closed contact is connected to the first circuit board 64 on the other side, or the normally closed contact and the common end contact are connected to the first circuit board 64 on the same side, and the normally open contact is connected to the first circuit board 64 on the other side. The reed switch 5 and the circuit frame 6 are directly fixed by metal contacts, which is not only conducive to automatic assembly, but also can reduce additional fixing brackets and reduce product costs.

[0042] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
