DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, specific embodiments of the present invention will be described in further detail based on the drawings. It should be understood that the description of the embodiments of the present invention is not intended to limit the protection scope of the present invention.
As shown in FIG.1 ~7, the electricity taking head 1000 of this embodiment includes a mounting base 100, an elastic electrical contact connector 200 disposed on the mounting base 100 and abutting against the conductive strip 2001 on the power supply rail 2000, and a rail connector 300 disposed on the mounting base 100.
The power supply rail 2000 is a flat structure, wherein one side is used for installation on the shelf, and the other side is provided with a conductive strip 2001 for distributing power to the shelf. The main body of the power supply rail 2000 is generally made of insulating material, which is flexible and flat. The electricity taking head 1000 is fixedly connected to the power supply rail 2000 through the rail connector 300, while the elastic electrical contact connector 200 abuts the conductive strip 2001 to achieve conduction, and transmits power to the power taker to supply power to the outside. The electricity taking head 1000 has an external connector 1001, which is a prior art and will not be repeated here.
For ease of description, in the present embodiment, the length direction of the power supply rail 2000 is defined as the longitudinal direction, the lateral direction of the power supply rail 2000 is defined as the lateral direction, and the direction perpendicular to the plane where the power supply rail 2000 is located is defined as the vertical direction.
In order to facilitate manufacturing, the rail connector 300 and the mounting base 100 are integrally molded and manufactured using elastic materials. The rail connector 300 and the mounting base 100 can be integrally molded to reduce costs. Generally, injection molding is used. The rail connector 300 includes two swing arms 301 and a press part 304, wherein the two swing arms 301 are spaced apart along the lateral direction. The connection where the swing arm 301 connects with the mounting base 100 is a rotation fulcrum 302. The end of the swing arm 301 is provided with a hook part 303, and two hook parts 303 are arranged oppositely, the connection and disconnection with the power supply rail 2000 are realized by controlling the proximity and separation of the two hook parts 303; the press part 304 is used to control the swing arm 301 to swing, and the press part 304 is spaced apart from the mounting base 100 to provide a pressing space, and is connected to two swing arms 301. When the press part 304 is pressed, the swing arm 301 is driven to swing outward about the rotation fulcrum 302 to make the two hook parts 303 is relatively open, and since it is made of an elastic material, after the external force is released, the two hook parts 303 are relatively closed. As shown in FIG.6, after pressing the two press parts 304, the electricity taking head changes from the upper state to the lower state.
The positional relationship between the rail connector 300 and the mounting base 100 is related to the structure of the power supply rail 2000. When a snap structure is provided in the middle area of the power supply rail 2000, the two hook parts 303 are located at the bottom of the mounting base 100. When the two hook parts 303 are directly snap-fitted with the two sides of the power supply rail 2000, the hook parts 303 are located on both sides of the mounting base 100 and can be set according to different connection positions.
The press part 304 is used to drive the swing arm 301, even if the swing arm 301 is subjected to a tangential force, in this embodiment, the press part 304 is formed by the swing arm 301 extending vertically upward. The press part 304 and the swing arm 301 are located on both sides of the rotation fulcrum 302, and when an external force is radially applied to the press part 304, the swing arm 301 swings.
In this embodiment, the swing arm 301 has a sheet shape, and the width direction of the swing arm 301 extends along the longitudinal direction. In order to make the hook part 303 connect with the power supply rail 2000 more reliably, the swing arm 301 has a certain width, which can increase the contact area between the hook part 303 and the power supply rail 2000 and increase the friction.
The rotation fulcrum 302 is in the form of a point in the cross section, but may be in the form of a segment or a point along the longitudinal direction. In this embodiment, the rotation fulcrum 302 is on the inner side of the swing arm 301 and is in a point shape along the longitudinal direction. The smaller the length of the rotation fulcrum 302 is, the easier it is for the press part 304 to drive the swing arm 301.
In this embodiment, corresponding to each swing arm 301, there are two rotation fulcrums 302, which are distributed along the longitudinal interval.
In order to facilitate manufacturing, in this embodiment, in the vertical projection of the swing arm 301, the hook part 303 and the rotation fulcrum 302 do not overlap. The above setting is convenient for demoulding after forming.
The mounting base 100 is used to carry the elastic electrical contact connector 200, the rail connector 300, and other structures conventionally possessed by the electricity taking head. In order to realize the installation and sealing of the elastic electrical contact connector 200, in this embodiment, the mounting base 100 includes an upper box body 101 with an opening at its bottom and a bottom cover 102. The elastic electrical contact connector 200 is arranged on the bottom cover 102 and is located in the upper box body 101. The elastic electrical contact connector 200 includes a fixing part 201 for external power supply and a elastic contact 202,and the bottom cover 102 is provided with an access hole 1021 through which the elastic contact 202 extends out. The upper box body 101 and the bottom cover 102 are fixedly connected, and there are many ways of fixing. In this embodiment, the bottom cover 102 is provided with a column 1022, the upper box body 101 is provided with a matching column hole 1011, and the column 1022 is inserted into the column hole 1011 for fixing connection. The upper box body 101 is also provided with a protrusion 1012 for pressing the fixing part 201.
The elastic electrical contact connector 200 has various forms in the prior art, such as a shrapnel type, a marble type, etc. In this embodiment, in order to simplify the structure, the fixing part 201 adopts a conductive sheet, and the elastic contact 202 is formed by the fixing part 201 extending downward, and the elastic contact 202 is bent downward and backward, and then bent upward and forward. The elastic contact 202 has an elastic sheet structure, which is simple in structure, convenient and low in manufacturing cost.
The bottom cover 102 is provided with a card slot 1023 for installing the fixing part 201.
In this embodiment, the two swing arms 301 are respectively arranged on both sides of the upper box body 101 and are integrally formed with the upper box body 101.
In order to reduce costs, in this embodiment, the elastic material is nylon or PC.
Generally, the circuit is divided into positive and negative poles. Therefore, in this embodiment, there are two elastic electrical contact connectors 200. One or more can also be set to adapt to different power supply technologies.
The electricity taking device of this embodiment includes a power supply rail 2000, a conductive strip 2001 arranged on the power supply rail 2000 and extending along the length direction, and the electricity taking head 1000 disposed on the power supply rail 2000. The hook parts 303 of the two swing arms 301 are respectively snap-connected to the two sides of the power supply rail 2000. One end of the power supply rail 2000 is provided with an end cover 2002, and the other end is provided with an external wiring 2003. The external wiring 2003 is fixed by fastening the upper cover body 2004 and the lower cover body 2005, and is electrically connected to the conductive strip 2001, where the electrical connection is realized by plugging.
