This invention generally relates to the technical field of lighting fixtures, and more particularly, to a track magnetic attraction power connection structure.
A lighting fixture is conventionally fixedly installed on a wall surface or a suspended ceiling. A table light is restricted by the length of a power cord and the position of a socket although it is capable of moving within a limited range. To achieve the purpose of atmosphere creation, the illumination area of an atmosphere light needs to be frequently adjusted. However, it is difficult for conventional fixing and installing methods to meet the demand of flexibly installing atmosphere lights. Presently, there is a large amount of research on the track-installation of atmosphere light products, aiming to achieve a flexible installation of atmosphere lights by means of a track.
Chinese patent CN209944254U discloses a track connector and a track light, comprising a housing, a first conductive member, a second conductive member, a knob assembly, a button switch device, a first communicating member, a second communicating member and a driving power supply, wherein the first conductive member and the second conductive member are arranged in the housing, the first conductive member has a first contact piece, and the second conductive member has a second contact piece. Two opposite side walls of the housing are respectively provided with a first opening and a second opening. The knob assembly is rotatably connected to the housing, and the knob assembly is configured to enable the first contact piece and the second contact piece to respectively extend out from the housing or retract into the housing from the first opening and the second opening. The knob assembly comprises a knob, and the knob is arranged at an upper end surface of the housing. The first communicating member and the second communicating member are arranged in the housing, and the second communicating member is configured to form an electrical connection with the second conductive member.
The structure of the conventional track connector is complex. First, the track connector needs to be fixedly installed on the track; second, the first contact piece and the second contact piece are controlled to extend out from the housing or retract into the housing from the first opening and the second opening by means of the knob assembly; and finally, the first communicating piece and the second communicating piece interact to form an electrical connection. The aforesaid structure results in difficult assembly and disassembly, inconvenient adjustment of installation position, complex structure and high cost.
Therefore, it is urgent to develop a novel track-installation structure.

Drawings and embodiments are combined hereinafter to further elaborate the technical solution of the present invention.
Referring to
The power connection assembly comprises an electrode plate 22, and the electrode plate 22 is fixedly arranged in the quick connector 2. The electrode plate 22 is provided with power connection terminals, and the power connection terminals pass through a first side wall of the quick connector 2. A first end of the power connection terminal is electrically connected to the electrode plate 22, and when the quick connector 2 is inserted into the sliding groove 11, second ends of two groups of power connection terminals respectively abut against a positive electrode conductive strip 13 and a negative electrode conductive strip 13 to form an electrical connection.
The power connection terminal comprises two elastic pins 23, and the two elastic pins 23 are spaced apart from each other. A first end of the elastic pin 23 is fixedly connected to the electrode plate 22, and a second end of the elastic pin 23 penetrates out from and is arranged on the first side wall of the quick connector 2. Preferably, the power connection terminal is provided with elastic pins, and when the quick connector 2 is inserted into the sliding groove, the elastic pin 23 abuts against the conductive strip 13, and the magnet 21 attracts the iron base plate 12. In this way, the quick connector 22 imposes an acting force on the iron base plate 12, which makes the connection between the elastic pin 23 and the conductive strip 13 become more stable. Further, any one of the power connection terminals is provided with two elastic pins 23, thereby ensuring that the electrode plate 22 always forms an electrical connection with the conductive strip 13 when any elastic pin 23 fails.
An inner wall of the first side wall of the quick connector 2 is provided with two magnets 21, the electrode plate 22 and the first side wall of the quick connector 2 are arranged in parallel, and the two magnets 21 are symmetrically arranged on two sides of the electrode plate 22. The two magnets 21 are symmetrically arranged on two sides of the electrode plate 22, which allows the elastic pins 23 to be uniformly stressed such that the stability of connection is ensured.
The quick connector 2 is provided with a locking structure, two inner side walls of the sliding groove 11 are respectively provided with a locking groove 14, and the locking structure is connected to the locking groove 14 in an interacting manner. Through adopting this arrangement, the quick connector 2 is connected to the track 1 in an interacting manner, and adjustable installation of the quick connector 2 along the sliding groove 11 is achieved. The locking structure is configured to prevent the quick connector from accidentally falling off when a failure occurs between the magnet 21 and the iron base plate 12. The locking structure merely prevents the quick connector 2 from falling off from the sliding groove 11, and the quick connector 2 slides along the track 1 through the interaction between the locking structure and the locking groove 14, thereby adjusting the installing position of the quick connector 2 in the track 1.
Referring to
The locking structure further comprises an unlocking bracket 26, and the unlocking bracket 26 is in transmission connection with the two protruding keys 24. The unlocking bracket 26 is capable of propelling the two protruding keys 24 to retract into the key holes 25, or the unlocking bracket 26 releases the two protruding keys 24 such that the two protruding keys 24 protrude out from the key holes 25. The unlocking bracket 26 propels the protruding keys 24 to extend out from or retract into the key holes 25 by adopting conventional means such as a buckle or a connecting rod, thereby locking the quick connector 2 in the sliding groove 11 or allowing the quick connector 2 to be unlocked and removed from the track 1.
The second side wall of the quick connector 2 is provided with a support 27. It should be understood that, the electrode plate 22 needs to be electrically connected to a lighting fixture or an electric appliance, and the quick connector 2 should have a connecting wire. Certainly, the support 27 may also be provided with an electrical connection structure in a contact manner, which enables the electrode plate 22 to be electrically connected to the lighting fixture or electric appliance.
The above are merely preferred embodiments of the present invention, and therefore, all equivalent changes or modifications made according to the structures, features and principles described within the scope defined by the claims of the present invention shall fall into the protection scope of the present invention.
