When the conductive track 100 is not installed with the conductive module 400, the mask 1 covers the front of the conductive track 100, which can prevent dust and protect, and also has a beautiful effect.

Figure 7 shows the conductive track 200 of the second preferred embodiment of the present application. In this embodiment, most of the structure is similar to that of the first preferred embodiment, and only the structure of the mask 1 is different. The cover portion 101 of the mask 1 is no longer a flat plate, but forms an arch in the middle portion. The first connection structure 103 is an interference fit structure, which forms an interference fit with the inner wall of the track body 3 .

The conductive rails 100 and 200 in the preferred embodiment of the present application can be directly installed on the roof, wall and other installation foundations. However, directly installing the conductive rails will protrude from the installation foundation. Therefore, the present application also proposes an embedded profile 6, as shown in Figure 5. As shown in Figure 6. The flush-mounted profile 6 includes a long groove 601 that can accommodate the conductive rails 100, 200. The depth of the groove 601 is less than the height of the conductive tracks 100,200. In the past, conductive rails were used for embedded installation, and their outer surfaces were usually equipped with buckle structures that could be matched with embedded profiles.

The conductive rails 100 and 200 are Remove the mask 1, securely connect it with the screw 2 and the embedded profile 6, then cover the mask, and the installation is completed.

The conductive module 400 provided by the preferred embodiment of the present application is shown in Figures 10, 11, and 12. The conductive module 400 is attached to the conductive track 100. The conductive module 400 can be a device such as a lamp, a sensor, a communication module, or a power adapter, with one end electrically connected to the conductive track 100 and the other end connected to various electrical equipment. The conductive module 400 shown in Figures 10 and 11 is an independent module and is not connected to electrical equipment. The conductive module 400 includes a housing 71, and the top of the housing 71 is provided with slide blocks adapted to the two slide grooves 301 respectively. In this embodiment, the slider is divided into a first slider 81 with a first conductive terminal 83 provided on the top, and a second slider 82 with a second conductive terminal 84 provided on the side. The first slider 81 and the second slider 82 are inserted into the chute 301 at the same time, the first conductive terminal 83 is electrically connected to the first conductive strip 404, and the second conductive terminal 84 is electrically connected to the second conductive strip 403. The first conductive terminals 83 and the second conductive terminals 84 are elastic terminals. The elastic terminals contact the first conductive strips 404 and the second conductive strips 403 during contact, thereby maintaining good contact.

In this embodiment, the first conductive terminal 83 and the second conductive terminal 84 are arranged on sliders of a separate structure. The two sliders are arranged front and back to make the conductive module 400 more stable when moving in the conductive track 100. Moreover, the two conductive terminals 83 and 84 are arranged in a separate structure. The terminals are not connected to each other There is interference. In other preferred embodiments, the first slider 81 and the second slider 82 can also be integrated into one body, and the first conductive terminal 83 and the second conductive terminal 84 are respectively provided on the top and side surfaces of the slider, in conjunction with the slide groove. The conductive strips in 301 match. The first conductive terminal 83 and the second conductive terminal 84 can be disposed at the same part of the slider, or they can be disposed front and back, which is not limited in this application.

In this embodiment, since the second conductive strips 403 are disposed on the side walls of the chute 301 close to each other, the two second conductive terminals 84 respectively inserted into the two chute 301 are arranged oppositely. In other embodiments, the arrangement of the second conductive terminal 84 can be changed according to the position of the second conductive strip 403, which is not limited in this application.

In the above embodiment, the first conductive strip 404 and the second conductive strip 403 are respectively arranged on the bottom surface and side wall of the chute 301, so that there is no need to increase the size in the width and height directions, and the overall structure is smaller. It should be noted that the bottom surface and side walls mentioned here are not necessarily two vertical surfaces. If a thinner structure is required, the bottom surface and side walls can form an obtuse angle, so that the height direction can be further thinned.

At the same time, without increasing the overall size, this application also provides another preferred embodiment, Embodiment 3, as shown in Figure 8 . The difference between the conductive track 300 of the third embodiment and the previous embodiment is that the cross-section of the isolation support 7 is U-shaped, as shown in FIG. 9 . The isolation support 7 includes a first isolation portion 702 that at least partially adheres to the bottom surface 3012 of the chute. The first conductive strip 704 is disposed on the opposite side of the side of the first isolation portion 702 that adheres to the bottom surface 3012 of the chute 301; The second isolation portion 701 of the side wall 3011 of the chute 301 and the second conductive strip 703 are disposed on the opposite side of the side of the second isolation portion 701 that is in contact with the side wall 3011 of the chute 301; at least partially in contact with the other side of the chute 301. The third isolation portion 706 of the side wall 3013 and the third conductive strip 707 are disposed on the opposite side of the side where the third isolation portion 706 is in contact with the side wall 3013 of the chute 301 . The first conductive strip 704, the second conductive strip 703, the third conductive strip 707 and the chute 301 are electrically isolated. Such a structure can add another transmission line, which is suitable for expansion needs. Matching this, the slider of the conductive module 400 is also provided with a third conductive terminal, and the third conductive terminal and the second conductive terminal are respectively provided on two opposite sides of the slider.

In order to realize the mechanical connection between the conductive module 400 and the conductive track 100, in the preferred embodiment 1, a connection slot 302 is provided between the two slide grooves 301 of the conductive track 100, and the conductive module 400 is provided with a connection that matches the connection slot 302. Item 72. The connecting member 72 is disposed between the two slide blocks inserted into the two slide grooves 301 in the width direction, that is, the connecting member 72 is disposed on the central axis along the moving direction of the conductive track 100 . In the length direction, the conductive module 400 is provided with a connector 72 at each of its front and rear ends along the moving direction of the conductive track 100 .

The opening end of the connecting groove 302 is provided with a snap-in portion 3021. In this embodiment, the snap-in portion 3021 is a hook protruding inward from the side wall of the opening end of the connection slot 302. In other embodiments, the snap-in portion 3021 can also be a hook protruding inward. The clamping groove on the inner wall of the connecting groove 302 is not limited in this application.

The connecting piece 72 is a locking structure, as shown in FIG. 13 , including a locking part 721, a handle part 722 and a fixed connection part 723. The fixed connection part 723 is connected to the housing 71 . By rotating the handle part 722 , the locking part 721 is driven to achieve locking engagement with the conductive rail 100 , thereby achieving fixation with the conductive rail 100 .

The locking part 721 includes a rotating shaft part 7211 and a turning part 7212. The rotating shaft portion 7211 is disposed on the handle portion 722 and is cylindrical in shape. One end of the rotating shaft portion 7211 is fixedly connected to the upper end surface of the handle portion 722. The other end of the rotating shaft portion 7211 away from the handle portion 722 has a rotating shaft. Department 7212. There are two turning parts 7212 , which are symmetrically arranged at the other end of the rotating shaft part 7211 away from the handle part 722 . In the horizontal cross-section, the two turn-in portions 7212 provided on the rotating shaft portion 7211 are waist-shaped. During installation, the turn-in part 7212 is first in the position shown in Figure 14, enters the connection groove 301, and rotates the handle part 722 to the position in Figure 15. The lock part 721 drives the turn-in part 7212 into connection through the rotating shaft part 7211 connected to the handle part 722. In the groove 302, the turn-in part 7212 is hooked on the clamping part 3021, thereby realizing the locking connection between the locking part 721 and the conductive track 100, as shown in Figure 16.

Of course, in addition to this rotating lock structure, the connecting piece can also adopt other forms, such as buckles, elastic bumps, etc. In addition, magnetic elements can also be provided on the connection slot 302 and the conductive module 400 respectively, and the connection can be carried out by magnetic attraction, which is not limited in this application.

When the conductive module 400 is connected to the conductive track 100, the installer cannot immediately find the required position. For example, when the conductive module 400 is connected to a lamp, it is often necessary to adjust the position multiple times and turn on the lamp to observe the lighting effect before finally deciding on the installation position of the lamp. Therefore, the conductive module 400 in the embodiments of Figures 10 and 11 is also provided with a pre-installed connection part 9. The pre-installed connection part 9 can temporarily fix the conductive module 400 to the conductive track 100 and can move on the conductive track 100. , only after the position is determined, the locking connection is performed through the connecting piece 72. Since it is a pre-assembled structure, the pre-installed connection part 9 has a snap-on structure and is snap-connected to the connection slot 302, so that it can be easily installed and removed from the snap-in slot.

Traditional buckle structures mostly use the deformation method of the vertical axis (that is, the force arm is on the vertical axis) to realize the deformation of the plastic during the assembly process. This method makes assembly easier when the vertical axis is long. However, when the vertical axis is very short, due to the constant moment, the shorter the moment arm, the greater the force exerted, making it difficult to elastically deform the plastic and difficult to assemble. The traditional buckle is shown in Figure 17. When the force arm is very short, the plastic part needs to be buckled and deformed into the metal part. The buckle needs a deformation angle of about 60°, which requires a lot of force, and manual operation is more complicated. Difficulty, and the bottom of the forced installation buckle may even break, causing the product to be defective and scrapped.

This application provides a conductive track structure with a thinner structure, which leaves little space for buckles. Therefore, the pre-assembled connection part 9 in this application adopts a new buckle structure suitable for short distances. The buckle structure of the pre-assembled connection part 9 includes two buckle structures arranged back to each other. The first embodiment of the buckle structure is shown in Figure 18. The buckle structure includes an elastic arm 92 connected to the mounting surface 901, and a buckle structure disposed on The buckling portion 91 on the elastic arm 92. In this embodiment, the mounting surface 901 is the top surface of the housing 71 of the conductive module 400. The elastic arm 92 includes a vertical force arm 921 perpendicular to the installation surface, and a longitudinal force arm 922 at a certain angle from the vertical force arm 92 . One end of the vertical force arm 921 is connected to the housing 71, and the other end is connected to the longitudinal force arm 922. The free end of the longitudinal force arm 922 is provided with a buckling portion 91. The bottom of the buckling portion 91 is suspended, and a gap is formed between it and the mounting surface 901. 93. The length of the vertical force arm 921 is d1, and the length of the longitudinal force arm 922 is d2. In order to be suitable for ultra-low height buckle structures, the length of d1 is less than d2. During installation, although d1 is very small, d2 can also provide deformation. The space makes the overall length of the arm longer without increasing the height of D1, making the installation easier and not causing damage. In this embodiment, the extending direction of the longitudinal force arm 922 is parallel to the mounting surface 901, that is, perpendicular to the vertical force arm 921. In other preferred embodiments, the longitudinal force arm 922 can also be tilted downward or upward, as long as it is buckled The bottom part 91 is still kept in the air, and the superposition of the force arms can also be formed to achieve the same effect.

Figure 19 shows a second embodiment of the snap structure in the pre-assembled connection part 9, which is an improvement of the first embodiment of Figure 18, In this embodiment, two vertical force arms 921 extend upward from the mounting surface 901, and the longitudinal force arm 922 connects the free ends of the two vertical force arms. The retaining portion 91 is disposed at the middle position of the longitudinal force arm. Of course, the retaining portion does not have to be disposed at the structural center of the longitudinal force arm. It can be deviated to one side as needed, and this application does not limit this. It is equivalent to the two elastic arms 92 in the first embodiment being arranged oppositely, and the buckling part 91 is arranged at the connection of the two elastic arms 92 . Such a structure makes the movable space of the buckling part 91 smaller than that of the first embodiment, and the overall structure is more stable.

Figure 20 shows the third embodiment of the buckle structure in the pre-assembled connection part 9. In this embodiment, one end of the longitudinal force arm 922 is connected to the mounting surface 901, and the other end is connected to the vertical force arm 921. The vertical force arm 921 Perpendicular to the mounting surface 901 , the retaining portion 91 is provided at the free end of the vertical force arm 921 . As an ultra-low height buckle, the length d1 of the vertical force arm 921 is smaller than the length d2 of the longitudinal force arm 922 . The longitudinal force arm 922 and the mounting surface 901 are located on the same plane, and a gap 93 is formed between the longitudinal force arm 922 and the mounting surface 901. Although d1 is small and will not increase the buckle height, the overall force arm of the elastic arm 92 is composed of d1, d2 is superimposed, which can form a larger deformation space and is easy to install.
