Description
Technical field：
It the utility model is related to pcb board construction applications, more particularly to liquid crystal backlight pcb board.
Background technology：
In existing structure, after terminal line is welded with pcb board, terminal line causes terminal line weld to break by repeatedly rocking
Split, generation is bad, influences quality.
Utility model content：
The utility model is intended at least solve one of technical problem existing in the prior art.
For this reason, its technical scheme applied to solve the technical problem of the utility model is：Liquid crystal backlight pcb board, including：
Pcb board, pcb board are in thin slice strip, are provided with LED light and positive and negative anodes pad on pcb board, positive and negative anodes pad is arranged at pcb board
One end the position by close end at, pcb board is arranged close to be further opened with one at the position of one end of positive and negative anodes pad
Perpendicular to the straight slot of pcb board length direction, the depth of straight slot is the 1/2~2/3 of pcb board width, straight slot and adjacent pcb board
The spacing of termination is 1cm~2cm, and the position between straight slot and the termination of adjacent pcb board is the end of a thread connecting portion, positive and negative anodes pad
On be welded with terminal line, the end of a thread connecting portion upper sleeve has heat-shrinkable T bush, and terminal line is stretched out from heat-shrinkable T bush.
Preferably, the end shaping of the end of a thread connecting portion is arc-shaped.
Preferably, pcb board is also installed with a transverse slat positioned at the opposite side for opening up straight slot side.
Preferably, pcb board is fixedly mounted on the center line of transverse slat, it is in T words that transverse slat and pcb board, which combine and to form cross section,
Shape.
The beneficial effects of the utility model are：
The utility model increases straight slot on original pcb board so that the end of a thread connection is formed in the end of pcb board
Portion, so that heat-shrinkable T bush can be inserted in, due to the pliability of heat-shrinkable T bush, terminal line external force can pass through heat-shrinkable T bush
Most of power is absorbed, terminal line and the positive and negative anodes pad on pcb board are fitted closely after heat-shrinkable T bush heating, so terminal will not be made
Stress at wire bonding, avoids terminal line weld phenomenon of rupture, improves the yield of product, more due to also solid on pcb board
A transverse slat, one cross section of composition structure in T shape, so that more convenient is fixed on the utility model are determined
Without being contacted with liquid crystal display on liquid crystal screen framework, the heat dissipation effect of pcb board ensure that.

Embodiment：
Embodiment 1：The backlight pcb board of liquid crystal as shown in Figure 1 and Figure 2, including：Pcb board 1, pcb board 1 are in thin slice strip
Shape, is provided with LED light 2 and positive and negative anodes pad 3 on pcb board 1, and what positive and negative anodes pad 3 was arranged at one end of pcb board 1 leans on close end
Position at, pcb board 1 is arranged close to be further opened with one at the position of one end of positive and negative anodes pad 3 to grow perpendicular to pcb board 1
The straight slot 4 in direction is spent, the depth of straight slot 4 is the 1/2~2/3 of 1 width of pcb board, between the termination of straight slot 4 and adjacent pcb board 1
Away from for 1cm~2cm, the position between straight slot 4 and the termination of adjacent pcb board 1 is the end of a thread connecting portion 5, is welded on positive and negative anodes pad 3
Terminal line 6 is connected to, 5 upper sleeve of the end of a thread connecting portion has heat-shrinkable T bush 7, and terminal line 6 is stretched out from heat-shrinkable T bush 7.
The end shaping of the end of a thread connecting portion 5 is arc-shaped.
Pcb board 1 is also installed with a transverse slat 8 positioned at the opposite side for opening up 4 side of straight slot.
Pcb board 1 is fixedly mounted on the center line of transverse slat 8, and to form cross section in T shape for transverse slat 8 and the combination of pcb board 1.
The above is only the preferred embodiment of the present invention, and those of ordinary skill in the art are not making creativeness
All other embodiments obtained under the premise of work, should all belong to the scope of the utility model protection.
