After the lower keel 2 is installed, a ceiling can be further installed on the installation flange, and the cavity 7 at the bottom of the lower keel 2 is exposed to provide a space for supplying power to the outside, so that the zero line conducting belt 10 and the live line conducting belt 12 are arranged in the cavity 7. In view of the risk of electrical energy, especially the risk of the live wire contacting alone and also having contacts, the live wire conducting strip 12 is hidden deep in the top surface of the cavity 7, whereas the neutral wire conducting strip 10, which is relatively safe, is arranged on both sides of the cavity 7.

The insulating protection glue 15 is blocked between the first electricity taking gap 46 and the live wire conducting belt 12, and even if the parts such as fingers of a human body accidentally pass through the first electricity taking gap 46, the parts can be protected by the insulating protection glue 15, so that the electricity utilization safety is further improved.

The power take-off terminal 41 is just the dedicated power take-off component mentioned above. The external electrical equipment is to take the power supplied by the keels, and the corresponding socket is to be provided, and the socket corresponds to the plug of the electrical equipment standardized on the market at present so as to meet the universality.

Because of the limitations of the manufacturing process, the length of the lower keel 2 manufactured is limited, and a connector 24 may be required to assist in connecting the two lower keels 2 and providing a connection for power. The structure of the connecting piece 24 is basically the same as that of the sealing head 16, but the connecting piece 24 is applied to the joint of the two lower keels 2, and the two side surfaces are required to be connected and connected electrically, so that the zero line connection part 26 and the live line connection part 27 for connecting and supplying power are exposed at the two side surfaces of the connecting piece 24 simultaneously.

The above-described technical solution of using the connecting piece 24 to connect and energize is convenient to install, and the components are standardized to a high degree, so that the components are convenient to repair and replace, but the appearance of the connecting piece 24 is affected to a certain extent. The above-described arrangement of the neutral connection plug piece 49 and the live connection plug piece 50 can completely eliminate the trace between the joint ends of the two lower keels 2, and is more attractive in appearance. However, since the neutral connection plug piece 49 and the live connection plug piece 50 are required to be connected to the ends of the neutral conductive tape 10 and the live conductive tape 12 respectively, the general connection method is welding, so that the production pressure in the production process of the internal field is increased, more working procedures are generated in the process of producing the neutral conductive tape 10 and the live conductive tape 12, and the maintenance is not convenient. The specific technical scheme can be selected according to actual conditions.

Preferably, the conductive ceiling grid further comprises a control assembly (not shown), wherein a control chip (not shown) and a plurality of relays (not shown) are arranged in the control assembly; the end socket 16 of each group of the lower keels 2 is electrically connected with a group of relays, and the relays are integrally arranged on a control chip.

The surface of the live wire conducting belt 12 is protected by the second protective baffle 31, and then the human body is prevented from contacting and electric shock through the narrower second electricity taking gap 47.

It is possible to add a neutral conductor 10 and a live conductor 12 to the upper track groove 4 for expansion of the keel product. The original lower keels 2 can be basically arranged along one direction, and the conductive auxiliary keels 33 can not be additionally arranged between the two side-by-side lower keels 2. Once the conductive structure is added to the upper track groove 4, however, the subsidiary runners 33 can be installed between two adjacent lower runners 2 by means of the conductive structure, inheriting the conductivity of the lower runners 2.

The electric conduction is realized by connecting the two ends with the zero line and the fire line respectively, which is a great characteristic of the auxiliary keel 33. Because the zero line mounting flange 28 and the live line mounting flange 29 of the same lower keel 2 are blocked by the clamping rail 1, direct electricity taking between the zero line mounting flange 28 and the live line mounting flange 29 of the same lower keel 2 is difficult to realize.

By virtue of the elasticity of the neutral contact 36, it is possible to ensure that the neutral contact 36 is in contact with the neutral conductor 10 and at the same time also to generate a traction force on the live contact 37, so that the live contact 37 is tightly connected with the live conductor 12. The fit between the live wire seal head 35 and the live wire mounting flange 29, and between the neutral wire seal head 34 and the neutral wire mounting flange 28 can ensure stable and firm assembly.

The internal structure of the auxiliary keel 33 is similar to that of the lower keel 2, wherein the structures of the auxiliary bone notch 40 and the auxiliary bone cavity 39 are consistent with the notch 8 and the cavity 7 of the lower keel 2, namely, the auxiliary keel 33 can be provided with the power taking terminal 41, so that the auxiliary keel 33 perfectly inherits the conductive performance of the lower keel 2, and then the keel product is not limited to a conductive network in one dimension but extends to a conductive network in two dimensions.

The conductive ceiling keel provided by the invention can supply power to the outside in all positions of the whole keel, so that any electrical equipment can be freely installed on the ceiling. The structure of the auxiliary keel 33 further inherits the conductivity of the lower keel 2, so that the keel product integrally forms a two-dimensional power supply network, and the conductivity of the keel is greatly improved.
