Description

Technical Field

[0001] The utility model relates to the technical field of display power supply, in particular to a two-way power supply incoming line connection mechanism for a display. Background Art

[0002] In the prior art, for the power supply of the spliced ​​display screen cabinet, wires are generally used for series connection. In order to facilitate the series connection, two interconnected female plugs can be provided on the power box of the display screen cabinet, which are respectively located on both sides of the power box. In this way, the male plug on the power wire only needs to be plugged into one of the female plugs. However, the connections between the two existing female plugs are directly connected through corresponding wires, such as Chinese utility model patent: CN202222627912.4, a six-way branch connector, including: a branch connector body, the branch connector body includes an intermediate wire part, two branch heads, and the branch head is designed with two conductive ends and two branch ends, a conductive plate is installed inside, the two conductive ends and the two branch ends are electrically connected to the PCB conductive plate, respectively, and then the two female ends of the wires in the intermediate wire part are respectively connected to the conductive ends on the two branch heads, so as to conduct the two branch heads, and the six-way branch connector is constructed by the above-mentioned structural design. When the operator uses the six-way branch connector, the six-way branch connector still retains two conductive ends and four branch ends, so that the six-way branch connector can be used to power four light sources and connect with other branch connectors.

[0003] The two female ends of the wires are connected through the middle wire part, and the wires are routed side by side. In the actual plug-in process, the male ends plugged in at both ends will be connected in the opposite order to the wires. In some high-demand application scenarios, the connection method of the male end and the wire must be consistent, which makes the above solution unable to be used normally, and it is easy to cause accidents by connecting the neutral wire and the live wire in reverse. Utility Model Content

[0004] In order to solve the above technical deficiencies, the utility model provides a two-way power supply line connection structure for a display, which is installed on a power box and can ensure one-to-one matching between the neutral wire, the live wire, and the ground wire when the male plug is plugged into the female plugs at both ends, so as to ensure safe and stable power supply.

[0005] The utility model discloses a two-way incoming line connection structure for a power supply of a display, comprising two female plugs, three wire insertion slots are arranged side by side inside the female plugs, a limiting ring is arranged on the front side wall of the female plug, and also comprises an incoming line male plug, the male plug is provided with three wire insertion posts, and a limiting buckle is arranged on the front side wall of the male plug, when the male plug cooperates with the female plug, the wire insertion posts are inserted into the wire insertion slots, and the limiting buckles are snap-connected with the limiting rings; the two female plugs are connected by three main wires, wherein the middle wire insertion slots are connected by a main wire, and the wire insertion slots on both sides are cross-connected by the main wires; the three wire insertion slots on one of the female plugs are respectively connected with branch wires, and the branch wires are used to provide power for the display.

[0006] When the two female plugs are connected to the power box of the display, they are respectively located at the two ends of the power box, and the front faces of the female plugs face outwards.

[0007] The utility model provides a two-way power supply incoming line connection structure for a display. When the female plug is installed on a power box, the front side of the female plug faces outwards, which makes it convenient for the male plug to be plugged in and out. Moreover, when the male plug cooperates with the female plugs at both ends, the correct connection of the neutral line, the live line and the ground line can be ensured, so as to ensure safe and reliable power supply.

[0010] Figure 3 It is a side view of the utility model (male plug is not shown). DETAILED DESCRIPTION

[0011] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0012] Embodiment 1:

[0013] like Figure 1 , Figure 2As shown, the utility model discloses a two-way incoming line connection structure for a power supply of a display, comprising two female plugs 1, three wire insertion slots 3 are arranged side by side inside the female plugs 1, a limiting ring 5 is arranged on the front side wall of the female plug 1, and also comprises an incoming line male plug 2, the male plug 2 is provided with three wire insertion posts 4, and a limiting buckle 6 is arranged on the side wall of the front side of the male plug 2. When the male plug 2 is matched with the female plug 1, the wire insertion post 4 is inserted into the wire insertion slot 3, and the limiting buckle 6 is snap-engaged with the limiting ring 5; the two female plugs 1 are connected by three main wires 7, wherein the middle wire insertion slots 3 are connected by a main wire 7, and the wire insertion slots 3 on both sides are cross-connected by the main wire 7; the three wire insertion slots 3 on one of the female plugs 1 are respectively connected with branch wires 8, and the branch wires 8 are used to provide power for the display.

[0014] When the two female plugs 1 are connected to the power box of the display, they are respectively located at two ends of the power box, and the front faces of the female plugs 1 face outwards.

[0015] Since display screens generally pursue compact structures, the structure of the power box in the display box also needs to be relatively compact, especially with a smaller thickness. Therefore, in the solution of the present application, a limiting ring 5 is set on the front of the female plug 1, and when the female plug 1 is connected to the power box, the front of the female plug 1 is facing outward, so the limiting ring 5 is located on the outside, so that the back of the female plug 1 can fit the inside of the power box without generating a gap, and the structure is more compact. In this way, when the male plug 2 is matched with the female plugs 1 on both sides, the direction of the male plug 2 will rotate 180°, resulting in the position of the wires on both sides of the male plug 2 being transposed, so the plug slots 3 on both sides of the two female plugs 1 need to be cross-connected through the main conductor 7, that is, the plug slot 3 on the upper side of one female plug 1 is connected to the plug slot 3 on the lower side of the other female plug 1 through a main conductor 7, the plug slot 3 on the lower side of one female plug 1 is connected to the plug slot 3 on the upper side of the other female plug 1 through a main conductor 7, and the plug slot 3 in the middle of the two female plugs 1 is connected through a main conductor 7. In this way, when the male plug 2 is plugged into different female plugs 1, the positions of the corresponding neutral wire, live wire, and ground wire always remain corresponding, which is safer during use. When the male plug 2 is plugged into the female plug 1, the limit buckle 6 of the male plug 2 is always located on the outside, which is convenient for plugging and unplugging.

[0016] The branch conductors 8 are connected one by one with the corresponding main conductors 7 and can supply power.

[0017] The male plug 2 and the female plug 1 can be standard parts of known technology, so that the structure is universal and the cost is lower. The structure of the limit ring 5 on the female plug 1 and the limit buckle 6 on the male plug 2 can adopt a common snap-fit ​​form, and the specific structure is an existing known structure and will not be described in detail.
