The conductive module 400 shown in fig. 10 and 11 is a separate module, and no electric device is connected. The conductive module 400 includes a housing 71, and sliders respectively fitted to the two sliding grooves 301 are disposed at a top end of the housing 71.

It should be noted that the bottom surface and the side wall as referred to herein are not necessarily two surfaces vertically arranged, and if a thinner structure is required, the bottom surface and the side wall may form an obtuse angle, so that they may be further thinned in the height direction.

Meanwhile, on the basis of not increasing the overall size, the application also provides a further preferred embodiment, namely a third embodiment, as shown in fig. 8. The conductive track 300 of the third embodiment differs from the previous embodiment in that the insulating support 7 is U-shaped in cross-section, see fig. 9. The isolation support 7 comprises a first isolation portion 702 at least partially abutting the bottom surface 3012 of the chute, and a first conductive strip 704 is disposed on an opposite side of the first isolation portion 702 abutting the bottom surface 3012 of the chute 301; a second isolation part 701 at least partially attached to the side wall 3011 of the chute 301, and a second conductive strip 703 is disposed on the opposite side of the side wall 3011 of the chute 301 to which the second isolation part 701 is attached; a third spacer 706 at least partially abutting another side wall 3013 of the chute 301, and a third conductive strip 707 is disposed on an opposite side of the third spacer 706 from the side wall 3013 of the chute 301.

The connecting member 72 is disposed at a position between the two sliders inserted into the two slide grooves 301, respectively, in the width direction, that is, the connecting member 72 is disposed on the central axis in the moving direction of the conductive rail 100. The conductive module 400 has a connector 72 at each of front and rear ends in the moving direction of the conductive track 100 in the longitudinal direction.

The open end of the connecting groove 302 is provided with a clamping portion 3021, in this embodiment, the clamping portion 3021 is a hook protruding toward the inner side of the side wall of the open end of the connecting groove 302, and in other embodiments, the clamping portion may also be a clamping groove formed on the inner side wall of the connecting groove 302, which is not limited in this application.

The connecting member 72 is a locking structure, as shown in fig. 13, and includes a locking portion 721, a handle portion 722 and a fixing connecting portion 723. The fixing connection portion 723 is connected to the housing 71, and the handle portion 722 is rotated to drive the locking portion 721 to achieve locking and clamping with the conductive rail 100, so that the fixing with the conductive rail 100 is achieved.

The rotating shaft portion 7211 is arranged on the handle portion 722, is cylindrical, and has one end fixedly connected with the upper end surface of the handle portion 722 and the other end of the rotating shaft portion 7211 far away from the handle portion 722 provided with a turning-in portion 7212. The two turning portions 7212 are symmetrically disposed at the other end of the rotation shaft portion 7211 away from the grip portion 722.

Of course, the connecting member may take other forms other than the rotary latch structure, such as a snap, an elastic projection, etc. In addition, magnetic elements may be respectively disposed on the connecting slot 302 and the conductive module 400, and the connecting slot and the conductive module are connected in a magnetic manner, which is not limited in the present application.

When the conductive module 400 is connected to the conductive track 100, an installer cannot find a required position immediately, for example, when the conductive module 400 is connected to a lamp, the installer often needs to adjust the position many times to light up and observe the lighting effect, so as to finally determine the installation position of the lamp. Therefore, the conductive module 400 of the embodiment shown in fig. 10 and 11 is further provided with a pre-assembly connecting portion 9, the pre-assembly connecting portion 9 can temporarily fix the conductive module 400 on the conductive track 100 and move on the conductive track 100, and after the position is determined, the conductive module 400 is locked and connected by the connecting member 72. Due to the preassembly structure, the preassembly connecting parts 9 are of a buckle structure and are clamped in the connecting grooves 302, and the connecting grooves can be conveniently installed and taken out from the clamping grooves.

The conventional snap structure mostly adopts a vertical shaft (i.e. a force arm is on the vertical shaft) deformation mode to realize the deformation of plastics in the assembling process, and the assembling is easier under the condition that the vertical shaft is longer. However, in the case of a short vertical axis, the shorter the moment arm, the greater the force applied, making elastic deformation of the plastic difficult and assembly difficult. As shown in FIG. 17, when the force arm is short, the plastic part needs to be buckled and deformed into the metal part, the buckle needs to be deformed by an angle of about 60 degrees, great force needs to be applied, manual operation is difficult, and even the situation that the bottom of the buckle is forcibly installed and is broken can occur, so that the product is poor and is scrapped.

The application provides a conductive track structure that the structure is thinner, and it is very little for the position of buckle that leaves, consequently pre-installation connecting portion 9 in this application has adopted a novel buckle structure who is fit for the short distance. The snap structure of the pre-assembly connecting part 9 comprises two snap structures arranged opposite to each other, the first embodiment of the snap structure being shown in fig. 18 and comprising resilient arms 92 connected to the mounting surface 901 and snap holding parts 91 arranged on the resilient arms 92. The mounting surface 901 in this embodiment is the top surface of the housing 71 of the conductive module 400. The resilient arm 92 includes a vertical force arm 921 perpendicular to the mounting surface and a longitudinal force arm 922 at an angle to the vertical force arm 92. One end of the vertical force arm 921 is connected with the shell 71, the other end is connected with the longitudinal force arm 922, the free end of the longitudinal force arm 922 is provided with a buckling part 91, the bottom of the buckling part 91 is suspended, and a gap 93 is formed between the buckling part 91 and the installation surface 901. The length of vertical arm 921 is d1, and the length of vertical arm 922 is d2, is less than d2 for being applicable to the length of super low-height joint structure d1, and when the installation, although d1 is very little, because d2 also can provide the deformation space for the arm is whole to be elongated and need not increase d1 height, and the installation is easier, and can not shine into the damage. In this embodiment, the extending direction of the longitudinal force arm 922 is parallel to the mounting surface 901, i.e. perpendicular to the vertical force arm 921, in other preferred embodiments, the longitudinal force arm 922 may also be inclined downward or upward, so long as the bottom of the fastening portion 91 is still suspended, the force arms may be stacked, and the same effect is achieved.

Fig. 19 shows a second embodiment of the snap-on arrangement in the pre-assembly connecting part 9, which is a modification of the first embodiment of fig. 18, in which two vertical force arms 921 project upwards from the mounting surface 901, the longitudinal force arms 922 connecting the free ends of the two vertical force arms. The buckling part 91 is arranged in the middle of the longitudinal force arm, and certainly, the buckling part is not necessarily arranged in the structural center of the longitudinal force arm and can be deviated to one side according to needs, and the application does not limit the structure. Corresponding to the two first embodiments in which the elastic arms 92 are oppositely disposed, and the clasping portion 91 is disposed at the junction of the two elastic arms 92. The movement space of the structure retaining part 91 is smaller than that of the first embodiment, and the whole structure is more stable.

Fig. 20 shows a third embodiment of the snap structure in the pre-assembly connector 9, in this embodiment, one end of the longitudinal arm 922 is connected to the mounting surface 901, the other end is connected to the vertical arm 921, the vertical arm 921 is perpendicular to the mounting surface 901, and the snap part 91 is disposed at the free end of the vertical arm 921. As an ultra-low height buckle, the length d1 of the vertical force arm 921 is less than the length d2 of the longitudinal force arm 922. A gap 93 is formed between the longitudinal force arm 922 and the mounting surface 901, although d1 is small and the buckle height cannot be increased, the whole force arm of the elastic arm 92 is formed by overlapping d1 and d2, a large deformation space can be formed, and the mounting is easy.
