DETAILED DESCRIPTION

[0024] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only some of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.

[0025] Example 1

[0026] like Figures 1 to 5 As shown, this embodiment designs a power connection structure of a display cabinet, including a strip-shaped power connection socket 2 and a power supply head 3.

[0027] The display cabinet includes a cabinet frame and a plurality of cabinet panels. The cabinet frame is formed by splicing aluminum profiles 1. The cabinet panels are connected to the cabinet frame to cover the top, side and bottom surfaces of the display cabinet. The cabinet panels may include a first cabinet panel 4 and a second cabinet panel 5 that are perpendicular to each other. When the aluminum profile 1 on which the strip-shaped power socket 2 is installed is the vertical support part of the cabinet frame, the second cabinet panel 5 may be a front side panel, and the first cabinet panel 4 may be a left side panel or a right side panel. When the aluminum profile 1 on which the strip-shaped power socket 2 is installed is the horizontal support part of the cabinet frame, the second cabinet panel 5 may be a front side panel, a left side panel, a right side panel or a rear side panel, and the first cabinet panel 4 may be a top panel or a bottom panel. A cardboard groove 13 may be provided on the aluminum profile 1, and the edge of the second cabinet panel 5 may be inserted into the cardboard groove 13, and one side of the first cabinet panel 4 is bonded and connected to the aluminum profile 1. The cabinet panels of the display cabinet may be made of transparent acrylic panels or glass.

[0028] A power supply groove 11 is provided on the side of the aluminum profile 1 for installing the strip-shaped power socket 2. The power supply groove 11 adopts a T-shaped groove structure. The strip-shaped power socket 2 is long and installed in the power supply groove 11. The strip-shaped power socket 2 can be used for connecting the power head 3 and for power transmission, so that the power supply line of the electrical equipment can be hidden in the power supply groove 11 of the aluminum profile 1, solving the problems of cable concealment and safety.

[0029] The strip-shaped power socket 2 includes components such as a strip-shaped insulating socket 21, a live metal strip 23 and a neutral metal strip 24. The live metal strip 23 and the neutral metal strip 24 are arranged on the strip-shaped insulating socket 21 in parallel and are exposed, so as to facilitate electrical connection with the power supply head 3. Since the strip-shaped power socket 2 is hidden in the power supply slot 11, it can effectively reduce accidental human contact. The end of the strip-shaped power socket 2 can be connected to the 220V mains power supply through a cable to improve convenience; it can also be connected to a low-voltage DC power supply below 36V to improve safety.

[0030] The power head 3 includes an insulating shell 35, a live wire contact piece 31, and a neutral wire contact piece 32. The live wire contact piece 31 and the neutral wire contact piece 32 are fixed on the outer wall of the insulating shell 35 and are in a state of extending outward. When the power head 3 is inserted into the power slot 11 and snap-connected to the notch of the power slot 11, the live wire contact piece 31 contacts the live wire metal strip 23, and the neutral wire metal strip 24 contacts the neutral wire metal strip 24. In addition, since the strip-shaped power socket 2 has a certain length, when the power head 3 is connected to any length position of the strip-shaped power socket 2, the live wire contact piece 31 and the neutral wire contact piece 32 can be connected to the live wire metal strip 23 and the neutral wire metal strip 24 correspondingly, and when the power head 3 slides along the length direction of the power slot 11, the live wire contact piece 31 keeps in contact with the live wire metal strip 23, and the neutral wire metal strip 24 keeps in contact with the neutral wire metal strip 24. This facilitates the change and adjustment of the installation position of electrical equipment such as LED lamps 6; at the same time, multiple power supply heads 3 can be connected in the length direction of the power supply slot 11, avoiding the line confusion problem caused by multiple LED lamps 6 and other electrical equipment drawing power from the same position.

[0031] When the live metal strip 23 and the neutral metal strip 24 are both located at the bottom of the power extraction slot 11, the spacing between the live metal strip 23 and the neutral metal strip 24 is equal to the spacing between the live contact piece 31 and the neutral contact piece 32. When the live metal strip 23 and the neutral metal strip 24 are both located on the slot walls on opposite sides of the power extraction slot 11, the spacing between the live metal strip 23 and the neutral metal strip 24 is greater than the spacing between the live contact piece 31 and the neutral contact piece 32, and the live contact piece 31 and the neutral contact piece are located on opposite sides of the insulating shell 35 of the power extraction head 3.

[0032] The bottom of the power receiving slot 11 is provided with a power receiving seat installation slot, and the power receiving seat installation slot adopts a T-shaped slot structure. The strip insulating seat 21 can be a T-shaped structure adapted to the power receiving seat installation slot, so that the strip insulating seat 21 can be snapped into the power receiving seat installation slot. Specifically: the upper and lower sides of the strip insulating seat 21 (refer to Figure 3 A lug is provided (in the direction of the power socket) which engages with the mounting groove of the power socket.

[0033] The insulating shell 35 is provided with a locking ridge 34 on two opposite sides. The cross section of the locking ridge 34 can be a trapezoid or a triangle. The locking ridge 34 is used to prevent the power head 3 from being removed from the power slot 11. When the insulating shell 35 is inserted into the power slot 11, the locking ridge 34 can be against the notch of the power slot 11 to prevent the power head 3 from falling off from the power slot 11 without the action of external force. When an external force is applied to the outside of the power slot 11, the locking ridge 34 will cause the notch of the power slot 11 to deform and increase the width of the notch, so as to pull out the power head 3.

[0034] The insulating shell 35 is provided with a wire hole 33 for passing the cable. The cable passes through the wire hole 33 to be electrically connected with the live wire contact piece 31 and the neutral wire contact piece 32 .

[0035] When the electrical device is an LED lamp 6 , a lamp trough 12 is further provided on the aluminum profile 1 , and the LED lamp 6 is embedded in the lamp trough 12 .

[0036] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
