Description

Small-spacing LED display screen assembly type power supply wiring three-way module and wiring harness

Technical Field

The utility model relates to a connector, wire rod, LED display screen technical field, specific theory has related to a booth apart from LED display screen assembled power line tee bend module and pencil.

Background

The LED display screen is a large-area playing picture formed by splicing a plurality of LED box bodies, and the LED display screen in the market at present has the requirements of light weight, thin thickness and dense dot matrix. Based on the demand, the small-spacing LED display screen product requires the box body to be ultrathin in thickness so as to reduce the weight, the product can be hung on a wall like a liquid crystal television, the high requirement on the thickness and the size of the LED display screen box body is brought, the current LED screen technology and the box body technology can meet the market requirement, and wiring becomes a short plate for limiting the lightness and thinness of the LED display screen product.

The box body of the LED display screen is connected through a signal line and a power line, signals are generally connected in series through RJ45 sockets in a point-to-point mode through network cables, connection is convenient and fast, and light and thin application is not affected.

The connection of power cord has a problem, and there are two kinds of connection modes at present:

one is to use three-way line, one box, main line is inserted to conduct current through joint, branch line is connected to L, N of AC-DC power supply and binding post of earth pole. However, the traditional tee joint is formed by injection molding, and the thickness of the box body is seriously influenced due to the high thickness. In addition, the conventional three-way joint is formed by welding brown, blue and yellow of three cables together respectively, so that the brown wires are welded to form one joint, the blue wires also form one joint, and the yellow wires also form one joint. However, even if the welding points are large and close to each other, the volume of the tee joint formed by injection molding is large, and the thickness at least exceeds 18mm (the wire of the LED display screen is generally 3 x 2.5mm 2), so that the size of the box body at least exceeds 20mm by adding the wall thickness of the box body, which is completely unfavorable for forming an ultra-thin box body, and the thickness size which is increased greatly is not necessary at all for the strength of the box body in view of the whole structure of the box body.

The second is two power cords of a box body, one end of each power cord is provided with a wire lug, and the other end of each power cord is provided with a butt joint. The wire lug is connected to L, N of an AC-DC power supply and a binding post of a ground pole. Thus, although the cost is low, the lug needs to be overlapped and assembled on the binding post, and the assembly difficulty of the lug is high.

In addition, even if an injection molding type ultrathin tee joint can be developed, due to the fact that orders of an LED display screen are complex and changeable, sizes of the LED display screen are not uniform, the specification of the tee joint is changeable, and great troubles are caused to production, and therefore the ultrathin assembling tee joint needs to be developed to solve a series of problems of universality, usability, ultrathin property and the like.
