Seamless splicing type LED circuit board

Abstract

The invention discloses a seamless splicing type LED circuit board, which comprises a four-way circuit board, a three-way circuit board, a left corner circuit board, a right corner circuit board and astraight-through circuit board. LED illuminating lamps are arranged on the surfaces of the four-way circuit board, the three-way circuit board, the left corner circuit board, the right corner circuitboard and the straight-through circuit board, and sockets and plugs are connected to the surfaces of the four-way circuit board, the three-way circuit board, the left corner circuit board, the rightcorner circuit board and the straight-through circuit board in a spot welding mode. The splicing of different line shapes can be realized through splicing of the four-way circuit board, the three-waycircuit board, the left corner circuit board, the right corner circuit board and the straight-through circuit board. The sockets are fixed to the surfaces of the four-way circuit board, the three-waycircuit board, the left corner circuit board, the right corner circuit board and the straight-through circuit board through spot welding, first positioning screws and bonding layers, and the plugs arefixed to the surfaces of the four-way circuit board, the three-way circuit board, the left corner circuit board, the right corner circuit board and the straight-through circuit board through spot welding, second positioning screws and bonding layers, so that the connection strength among the sockets, the plugs and the circuit boards is enhanced.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a seamlessly spliced ​​LED circuit board. Background technique [0002] At present, the light source modules on the market that splice multiple light-emitting units together usually fix the socket and plug on the surface of the circuit board by spot welding, and then splice through the horizontal insertion between the socket and the plug between the circuit boards to realize Seamless splicing between circuit boards. [0003] However, the connection position between the socket and the plug and the conductive part of the circuit board through spot welding is easy to be damaged when splicing between the socket and the plug, resulting in damage to the circuit board; and the horizontal splicing between the socket and the plug is usually connected by direct insertion , the lack of corresponding positioning, which will easily lead to loosening of the connection and poor contact....
