Referring to fig. 1 to 8, in the embodiment of the present invention, the magnetic lamp connector includes:
a lamp body end fitting 500, the lamp body end fitting 500 comprising:
a first housing 510, the first housing 510 having a receiving space;
a first insulator 520, the first insulator 520 being disposed in the first housing 510 such that the lamp body end fitting 500 has a first mounting cavity 511 and a second mounting cavity 512 which are independent of each other;

a second housing 610, the second housing 610 having a receiving space;
a second insulator 620 disposed in the second housing 610 such that the power terminal connector 600 has a third mounting cavity and a fourth mounting cavity that are independent of each other;
a second electrode 330 and a second magnetic member 350, wherein one of the second electrode 330 and the second magnetic member 350 is installed in the third installation cavity, and the other one is installed in the fourth installation cavity;
the magnetic lamp connector has a working circuit having two circuit openings, in a working state, the first electrode 310 is connected with the second electrode 330 to close one of the circuit openings, and the first magnetic member 320 and the second magnetic member 350 are magnetically attracted to close the other circuit opening.
Specifically, in this embodiment, the magnetic lamp connector includes a lamp body end connector 500 and a power supply end connector 600, where the lamp body end connector 500 is used to connect the lamp body 100, such as an LED lamp bead and a lamp panel; the power terminal 600 is used to connect to the power source 200 and supply power to the lamp body 100. When the lamp body end connector 500 and the power source end connector 600 are connected, the power source 200 and the lamp body 100 are turned on, so that the lamp body 100 is lighted. The magnetic lamp connector is provided with a working circuit which is electrically connected with the lamp body end connector 500 and the power supply end connector 600, the circuit is provided with two circuit openings, and the circuit can be positioned on the same electrode side and also can be a circuit on which a positive electrode and a negative electrode are respectively positioned.
For example, the positive electrode of the power supply 200 is connected to the second electrode 330 of the power terminal connector 600, and the negative electrode of the power supply 200 is connected to the second magnetic member 350 of the power terminal connector 600; the positive electrode of the lamp body 100 is connected to the positive electrode of the lamp body end connector 500, and the negative electrode of the lamp body 100 is connected to the first magnetic member 320 of the lamp body end connector 500. The first magnetic member 320 and the second magnetic member 350 are magnetically attracted, and when the first magnetic member 320 and the second magnetic member 350 are attracted together, the negative electrode of the lamp body 100 is connected with the negative electrode of the power supply 200 through the first magnetic member 320 and the second magnetic member 350; when the first electrode 310 is connected to the second electrode 330, the positive electrode of the lamp body 100 is connected to the positive electrode of the power supply 200 through the first electrode 310 and the second electrode 330, so that the positive electrode and the negative electrode of the lamp body 100 are respectively connected to the positive electrode and the negative electrode of the power supply 200, and thus the lamp body 100 is powered on and thus lighted. When the power source terminal connector 600 and the lamp body terminal connector 500 are separated, the first electrode 310 and the second electrode 330 are separated, so that the positive electrode of the lamp body 100 is separated from the positive electrode of the power source 200; the first magnetic member 320 is separated from the second magnetic member 350 such that the negative electrode of the lamp body 100 is separated from the negative electrode of the power source 200.
Of course, in some embodiments, the positive electrode of the power source 200 may be connected to the second magnetic member 350, the negative electrode of the power source 200 is connected to the second electrode 330, the positive electrode of the lamp body 100 is connected to the first magnetic member 320, and the negative electrode of the lamp body 100 is connected to the first electrode 310. In this way, the first and second magnetic members 320 and 350 connect the positive electrodes of the lamp body 100 and the power supply 200, and the first and second electrodes 310 and 330 connect the negative electrodes of the lamp body 100 and the power supply 200. Regarding the positional relationship between the first magnetic member 320 and the first electrode 310, the first magnetic member 320 may be mounted in the second mounting cavity 512, and the first electrode 310 may be mounted in the first mounting cavity 511, or the first magnetic member 320 may be mounted in the first mounting cavity 511, and the first electrode 310 may be mounted in the second mounting cavity. Similarly, the positional relationship between the second electrode 330 and the second magnetic member 350 is equivalent to the positional relationship between the first electrode 310 and the first magnetic member 320, and it should be noted that the second electrode 330 is disposed corresponding to the first electrode 310, and the second magnetic member 350 is disposed corresponding to the first magnetic member 320, so as to ensure the connection between the first electrode 310 and the second electrode 330, and the connection between the first magnetic member 320 and the second magnetic member 350 is reliable.
The first housing 510 and the second housing 610 may be made of various materials, such as plastic insulating material, stainless steel material, etc., and the outer wall surface thereof is coated with an insulating layer. The first housing 510 and the second housing 610 may be separately disposed, and in some embodiments, the first housing 510 and the second housing 610 may also be integrally formed under special operating conditions. The first insulating member 520 and the second insulating member 620 may be made of various materials, such as plastic, rubber, ceramic, etc.
Note that the magnetic material is a component having a magnetic attraction ability (a permanent magnet, a magnet, an electromagnet, or the like) or a magnetic attraction ability (metallic iron). At least one of the first magnetic member 320 and the second magnetic member 350 may be a permanent magnet, and the other may be a permanent magnet or an iron member.
In this embodiment, the first housing 510 is separated by the first insulating member 520 to form the first mounting cavity 511 and the second mounting cavity 512 which are independent from each other, so that the first electrode 310 and the first magnetic member 320 are not electrically connected, thereby avoiding a short circuit phenomenon in the lamp body end connector 500, and meanwhile, the second housing 610 is separated by the second insulating member 620 to form the third mounting cavity and the fourth mounting cavity which are independent from each other, so that the second electrode 330 and the second magnetic member 350 are not electrically connected, thereby avoiding a short circuit phenomenon in the power supply end connector 600; then, the connection between the first electrode 310 and the second electrode 330 and the connection between the first magnetic member 320 and the second magnetic member 350 are respectively used as a working mode for closing two circuit openings of a working circuit, so that the connection between the lamp body end connector 500 and the power supply end connector 600 is very safe and reliable; meanwhile, the connection between the lamp body end connector 500 and the power supply end connector 600 is realized through the connection between the first magnetic part 320 and the second magnetic part 350, so that the lamp body end connector 500 and the power supply end connector 600 are convenient and quick to mount and dismount, and quick replacement and maintenance are facilitated.
There are many ways to form the first mounting cavity 511 and the second mounting cavity 512, and many ways to form the third mounting cavity and the fourth mounting cavity, which are described below by way of example:
in some embodiments, in order to improve the space utilization rate and the structural compactness of the first housing 510 and the second housing 610, the first housing 510 is disposed in a cylindrical shape, the first insulating member 520 is disposed in a cylindrical shape, the first housing 510 is sleeved outside the first insulating member 520, and a first mounting cavity 511 is formed between an inner side wall of the first housing 510 and an outer side wall of the first insulating member; the first insulating member 520 is internally provided with a second mounting cavity 512; and/or the presence of a gas in the gas,
the second shell 610 is arranged in a cylindrical shape, the second insulating part 620 is arranged in a cylindrical shape, the second shell 610 is sleeved on the outer side of the second insulating part 620, and a third installation cavity is formed between the inner side wall of the second shell 610 and the outer side wall of the second insulating part; the second insulator 620 has a fourth mounting cavity formed therein.
Specifically, in this embodiment, the first housing 510 and the first insulating member 520 are coupled in many ways, for example, an end of the first insulating member 520 is coupled to an end of the first housing 510, and the two are coupled by an end plate. Thus, the inner side of the circular ring-shaped end plate is fixedly connected with the end of the first insulating member 520, and the outer side of the circular ring-shaped end plate is fixedly connected with the end of the first housing 510, so that the first installation cavity 511 is an installation space with one end open and the other end closed. Of course, in some embodiments, the first housing 510, the first insulator 520, and the end plate may be integrally formed. The first electrode 310 is mounted in the open end of the first mounting chamber 511. The first electrode 310 may have many forms, such as a block shape, and is disposed in the first mounting cavity 511, or may have a continuous ring shape, and is disposed on the outer sidewall of the first insulating member 520. Specifically, one end of the first housing 510 is fixedly connected to one end of the first insulating member 520, so that the first mounting cavity 511 is open at one end; the first electrode 310 is annularly sleeved outside the first insulating member 520; the first magnetic member 320 is installed at one end of the first insulating member 520 near the opening of the first installation cavity 511. In this way, the first electrode 310 is disposed in a ring shape and sleeved on the outer sidewall of the first insulating member 520, so that the first insulating member 520 is stably and reliably mounted. Meanwhile, only one end of the first electrode 310 is opened and is blocked, so that the influence of external environmental factors (such as dust, water, winged insects and the like) on the working stability of the source end connector is reduced.
Of course, in some embodiments, in order to protect the first electrode 310 and/or the first magnetic member 320, an elastic member 530 is further disposed in the first mounting cavity 511. Specifically, an elastic member 530 is further disposed in the first mounting cavity 511, the elastic member 530 is sleeved on the outer side of the first insulating member 520, one end of the elastic member 530 abuts against the closed end of the first mounting cavity 511, and the other end abuts against the first electrode 310; in the non-operating state, an end of the first electrode 310 away from the elastic member 530 protrudes out of the opening of the first mounting cavity 511. The elastic member 530 may have many forms, such as a spring plate, and the like, in this embodiment, the spring is taken as an example, the spring may be a small spring, and a plurality of springs are arranged along the circumferential direction of the first mounting cavity 511, and of course, the spring may also be a large-diameter spring, and the spring is sleeved outside the first insulating member 520, and one end of the spring abuts against the end plate, and the other end abuts against the first electrode 310. When the first magnetic member 320 is connected to the second magnetic member 350, due to the magnetic attraction, the elastic member 530 is disposed to buffer the impact generated during the magnetic attraction, so as to reduce the impact of the first electrode 310 and the second electrode 330, and the impact of the first magnetic member 320 and the second magnetic member 350 during the connection process, thereby improving the working stability and prolonging the service life.
The two ends of the second mounting cavity 512 are open, and the first magnetic element 320 is mounted in the second mounting cavity 512 in many ways, the first magnetic element 320 may be clamped at one end close to the first electrode 310, or the first magnetic element 320 may be limited in the second mounting cavity 512 by the limiting member 580, or of course, in some embodiments, the first magnetic element 320 may be matched with the second mounting cavity 512, and may also be limited by the limiting member 580.
