Description

Technical Field

[0001] The utility model relates to the technical field of power lines, in particular to a power transmission structure of a hard track lamp. Background Art

[0002] Existing hard track lights include a hard track and a sliding lamp base with a lamp that is slidably set on the hard track. A conductive strip is set in the track of the hard track. The sliding lamp base is slidably set in the track and obtains power from the conductive strip through a spring that contacts the conductive strip. The conductive strip is connected to an external power cord to obtain power. With this structure, once the length of the hard track is determined, it is difficult to change. It is difficult to obtain a hard track of the required length by cutting the profile according to site needs. Moreover, an external power cord is required, which is very inconvenient to use. It is not possible to set various forms of light sources to obtain light sources of various properties. Summary of the Invention

[0003] The purpose of the invention of the present utility model is to provide a power transmission structure for hard track lamps that can overcome one or more of the above-mentioned shortcomings, can quickly and easily obtain hard rails of required lengths by cutting profiles according to on-site needs, and can be equipped with other forms of light sources.

[0004] The utility model is implemented as follows: it includes a U-shaped hard rail profile, a quick-connect cable, and a sliding base. The quick-connect cable includes an insulator and two or more wires arranged side by side on the insulator. The quick-connect cable is a built-in quick-connect cable with all the wires buried in the insulator, or the quick-connect cable is an exposed quick-connect cable with part of the wires exposed. The bottom of the U-shaped recess of the U-shaped hard rail profile is provided with a quick-connect cable embedding groove, and positioning grooves are provided on both inner side walls of the U-shaped recess of the U-shaped hard rail profile. The sliding base is slidably arranged in the U-shaped recess and is positioned by a hook structure positioned on the positioning groove on the sliding base. The sliding base is provided with a guide hole directly reaching the quick-connect cable, and a conductive quick connector is provided in the guide hole. The conductive quick connector includes an inlay component with a positioning clip and a conductive head arranged on the inlay component. The conductive head of the conductive quick connector embedded in the guide hole rests on the wire of the quick-connect cable so that the wire of the quick-connect cable is conductively connected to the electrical facilities or wires on the sliding base.

[0005] When in use, the U-shaped hard rail profile is cut according to the required length, and the quick-connect cable is embedded in the quick-connect cable embedding groove. Of course, the quick-connect cable is also cut according to the required length. The sliding base is set on the U-shaped recess, and then moved to the required position of the U-shaped hard rail profile. The position of the sliding base is fixed by the hook structure, and the conductive quick connector is inserted into the guide hole so that the conductive head contacts the wire of the quick-connect cable (if the quick-connect cable is an internal quick-connect cable, the conductive head is a needle-type conductor, which penetrates the insulator and connects to the wire inside the insulator; if the quick-connect cable is an exposed quick-connect cable, the conductive head is a blunt-type conductive head, and the wide contact surface of the conductive head is close to the exposed wire). Power is supplied to the electrical facilities (such as electric light sources) or wires on the sliding base through the quick-connect cable; at the same time, the quick-connect cable outside the U-shaped hard rail profile can be connected to electrical facilities (such as electric light sources) by quick connection, which enriches the variety of light sources and the diversity of lighting, and facilitates the user's light source setting and use.

[0006] Preferably, a pair of wire clips are provided, which include inlays with positioning clips. The two ends of a section of quick-connect cable in the U-shaped hard rail profile are positioned in the U-shaped hard rail profile through the pair of wire clips, so that the quick-connect cable with a length much longer than the straight-line distance between the pair of wire clips falls and is exposed outside the U-shaped hard rail profile. The electrical facilities with quick-connect structures can be quickly connected to the quick-connect cable that has fallen and is exposed outside the U-shaped hard rail profile, thereby enriching the application scenarios and lighting design.

[0007] Preferably, one end of the embedded component of the conductive quick connector is hingedly connected to one side of the guide hole via an axis, and the other end of the embedded component is fixed to the other side of the guide hole. During use, the embedded component is pressed toward the guide hole, causing it to swing along the axis into the guide hole, so that the conductive head on the embedded component is close to the quick-connect cable, making close contact with the wires on the quick-connect cable. When the embedded component is fully inserted into the guide hole, the other end of the embedded component can be fixed to the hook on the other side of the guide hole to position the conductive quick connector in the guide hole.

[0008] Preferably, a sealing member is provided at the end of the U-shaped hard rail profile. The sealing member includes a decorative head and an inlay block that fits into the U-shaped recess of the U-shaped hard rail profile. The inlay block is provided with a hook structure that secures the sealing member to the end of the U-shaped hard rail profile. A cable recess is provided at the bottom of the decorative head. The quick-connect cable leading from the end of the U-shaped hard rail profile passes through the cable recess and is led out of the outside of the decorative head. The sealing member secures the quick-connect cable within the quick-connect cable recess of the U-shaped hard rail profile. Simultaneously, the U-shaped hard rail profile end is modified and the cable recess is provided, allowing the quick-connect cable to be smoothly led out of the sealing member.

[0009] Compared with the existing technology, the utility model has the advantages of being able to obtain hard rails that meet the required length by cutting profiles conveniently and quickly according to site needs, the quick-connect cables can be conveniently cut according to the required length, and other forms of light sources can be set.
