Detailed ways

In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field of the present invention. Terms used in the description of the present invention are only for the purpose of describing specific embodiments, and are not used to limit the present invention. The term "and/or" used in this specification includes any and all combinations of one or more of the associated listed items.

Existing track systems consist of a track and an adapter unit that mounts to the track with a "key" or "contact arm" system. The downside of this system is that not only does it make the entire track system significantly thicker, but the protruding adapters act as an additional hindrance during normal use. When not in use, the adapter protrusion still provides an additional hindrance and requires additional storage space. Adapter protrusion also exacerbates the mechanical weakness of the "key" or "contact arm" as it provides an additional point to apply torque, increasing the point of failure.

FIG. 1 shows an embodiment of the power distribution device of the present invention, including: a track 1 and an adapter 2 installed in the track 1 for taking power. The upper end surface of the adapter 2 is flush with the upper end surface of the track 1 .

There is an accommodation space inside the track 1, and the adapter 2 is installed in the accommodation space. The depth of the accommodation space is equal to, slightly larger than or slightly smaller than the thickness of the adapter 2 . In this way, the upper end surface of the adapter 2 can be made to be flush or close to the upper end surface of the rail 1 .

The upper end surface of the adapter 2 is flush with the upper end surface of the track 1 , which can prevent the adapter 2 from protruding from the track 1 and reduce the occupied space of the adapter 2 . And avoid touching the adapter 2 by mistake, and improve the safety of the adapter 2 . Reduced points of failure for Adapter 2.

The adapter 2 includes a strong current adapter, a weak current adapter and/or a data transmission adapter.

Strong power adapters include Chinese sockets, British standard sockets, German standard sockets, French sockets, Italian sockets, American sockets, etc.

Weak current adapters include USB charging adapters, wireless charging adapters, Bluetooth speaker adapters, etc.

Data transmission adapters include HDMI adapters, USB data transmission adapters, network data transmission adapters, control switch adapters, etc.

As shown in FIG. 1 and FIG. 2 , the upper side of the track 1 has an opening, and the upper side of the track 1 is provided with a sealing structure 4 for sealing the opening.

The track 1 is sealed by the sealing structure 4 to prevent dust from entering the accommodation space in the track 1 .

The sealing structure 4 has two usage states, including an open state and a closed state. When in an open state, the adapter 2 is exposed to facilitate taking power. In the closed state, when the sealing structure 4 is closed, the opening is sealed to prevent dust from entering the accommodation space in the track 1 .

A plurality of adapters 2 can be arranged in the track 1 , the openings at the corresponding positions of the adapters 2 are connection ports 11 , and the openings can be divided into a plurality of connection ports 11 by the adapters 2 .

In terms of size, the size of the sealing structure 4 is adapted to the size of the opening or at least one connection port 11 .

When the sealing structure 4 is opened, the opening of the track 1 is opened , all the adapters 2 can be exposed to take power. When the sealing structure 4 is closed, the opening of the track 1 is sealed to prevent the entry of dust. However, this sealing method can only open or seal the opening as a whole. When multiple adapters 2 are installed in the track 1 and only one of the adapters 2 is used, dust can easily enter the track 1 from the position of other adapters 2, which is safe. Sex is poor.

Preferably, the size of the sealing structure 4 matches the size of the connecting port 11 . Taking one connection port 11 as an example, that is, the connection port 11 is correspondingly provided with a sealing structure 4 , and one sealing structure 4 can seal one connection port 11 . When a sealing structure 4 is opened, the adapter 2 at the corresponding position can be exposed to take power, while the sealing structures 4 at other positions can be opened or closed. The opening or closing of the corresponding connection port 11 can thus be individually controlled by the sealing structure 4 . In this way, dust can be prevented from entering the connection ports 11 corresponding to the other adapters 2 when one of the adapters 2 is in use.

Structurally, the sealing structure 4 can be an integral structure or a split structure. When the sealing structure 4 is an integral structure, the size of the sealing structure 4 is adapted to the size of the opening or the connection port 11, and the opening or the connection port 11 is sealed. . When the sealing structure 4 is a split structure, the sealing structure 4 is composed of multiple sealing substructures, and the size of the multiple sealing substructures when combined is adapted to the size of the opening or connecting port 11, and the opening or connecting port 11 is sealed. .

The track 1 includes a bottom plate, and a first side plate 12 and a second side plate 13 extending upward from the front and rear sides of the bottom plate.

In terms of connection, the connection manner between the sealing structure 4 and the track 1 includes hinged joints, clip joints or lap joints.

When hinged, the position of the sealing structure 4 can be determined by the transition fit between the hinge shaft and the seal structure 4 , and the transition fit between the hinge shaft and the track 1 . The transitional fit tolerance is preferably H6/k5, and when there is no external force, a certain frictional force at the mating part can prevent the sealing structure 4 from rotating relative to the track 1 . When there is a certain external force, the sealing structure 4 can be rotated relative to the track 1 by the external force. An external force can also be applied to the sealing structure 4 through the torsion spring 2832 to cover the sealing structure 4 on the opening or the connection port 11 of the track 1 . For example, when one side of the sealing structure 4 is hinged on the front end of the first side plate 12, one end of the torsion spring 2832 is in contact with the inner wall of the first side plate 12 of the track 1, and the other end of the torsion spring 2832 is in contact with the inner wall of the sealing structure 4. Up, so that the sealing structure 4 can be rotated from bottom to top with the hinge shaft as the axis, and when the sealing structure 4 is perpendicular to the first side plate 12, the sealing structure 4 can be limited to avoid the sealing structure 4 Excessive rotation to the upper side of the opening. When limiting the sealing structure 4 , a baffle can be extended downward from the front end of the second side plate 13 to limit the sealing structure 4 .

It is also possible to arrange two of the lines of a set of cables 3 on the front, rear and/or underside of the track 1 .

The present invention can have multiple live wires to form multiple groups of single-phase power supplies. Furthermore, the present invention can individually control each group of single-phase power sources, and also significantly increase the transmittable power. For example, a single set of single-phase power supplies can carry 20A/250V (5000W), and each additional set of single-phase power supplies will double the power. Therefore, two groups allow (5000W x 2 = 10000W) of power. This calculation applies to any combination of single-phase power sources, such as 16A/110V, 32A/250V, 10A/250V, etc.
