Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a lamp body connector and a lamp for a track lamp. Background Art

[0002] The track light includes a lamp body and a track. The lamp body is installed on the track. The interior of the track contains a voltage input (220V AC input in China, and low-voltage input can also be customized). Conductive metal strips are provided on both sides of the track (high-quality ones are made of copper, and low-quality ones are made of iron), and conductive metal sheets are provided at the joints of the lamp body. During installation, the conductive metal sheets on the lamp body are in contact with the conductive metal strips inside the track, thereby enabling the lamp body to be energized.

[0003] At present, the existing lamp bodies are mainly connected to the track in the following three ways: fixed connection, slider connection and magnetic connection. Among them, the fixed connection is mainly achieved by screw connection. The defect of this connection method is that the lamp body cannot be adjusted and cannot be disassembled, and the lamp body cannot be replaced. The slider connection method is mainly to set a slider on the lamp body and connect it to the track through the slider. When installing, the lamp body needs to be inserted into the track from the end of the track, and then the installation position is adjusted by moving the lamp body. When disassembling, the lamp body needs to be moved to the end of the track before it can be removed. When the track is long, the lamp body to be removed needs to move a long distance to disconnect it from the track. When there are many lamp bodies on the track, the lamp bodies that hinder its removal need to be removed one by one to achieve the removal of the lamp body. Disassembly and installation are both troublesome and inconvenient to use. The magnetic connection method uses permanent magnets to achieve a detachable connection between the lamp body and the track. However, the connection between the lamp body and the track connected by the magnetic connection method is not strong enough and is easily affected by external forces, causing the lamp body to fall off the track. In addition, permanent magnets are expensive, resulting in high costs and limited use, which is not conducive to promotion and application.

[0004] In order to solve the above technical problems, the applicant has developed a suspension component that allows the lamp body to be reliably installed on the track and can be freely disassembled and assembled. In order to ensure that the lamp body can be reliably connected to the suspension component, it is necessary to develop a lamp body connector for a track light that can be compatible with the suspension component.

The clamping portion 21 is used to be engaged with the clamping hole on the suspension member 8 so that the insulating shell 1 can be reliably installed on the suspension member 8; the torsion spring 3 is installed in the cavity 111 and is used to provide elastic support for the slider 2. The first extension arm of the torsion spring 3 contacts one of the two adjacent sliders 2, and the second extension arm of the torsion spring 3 contacts the other of the two adjacent sliders 2, so that the clamping portion 21 can remain in a state of extending out of the insulating shell 1, so that the clamping portion 21 can be firmly engaged with the clamping hole of the suspension member 8.

[0030] During installation, the track light can be first fixed on the lamp body 10 with the lamp body connector, and then the insulating shell 1 is made to approach the bottom of the hanging member 8 with its top to make the snap-on portion 21 contact with the connecting portion on the hanging member 8, so that the snap-on portion 21 is retracted into the cavity 111 and the snap-on portion 21 is disengaged from the connecting portion on the hanging member 8. The snap-on portion 21 extends outward under the thrust of the torsion spring 3 and is reliably embedded in the snap-on hole on the connecting portion, thereby realizing a reliable connection between the lamp body 10 and the hanging member 8. During disassembly, the snap-on portion 21 is retracted into the cavity 111 by pushing it, thereby disengaging the snap-on portion 21 from the snap-on hole on the hanging member 8, and then the lamp body 10 is pulled in a direction away from the hanging member 8 to realize disassembly, with reliable connection and convenient assembly and disassembly.
