Abstract
The utility model relates to a fixed column and a light-emitting diode module with the fixed column, wherein the light-emitting diode module is provided with a printed circuit board, the fixed column fixed and welded on the printed circuit board is provided with a stud bolt and a positioning column arranged at one end of the stud bolt, a through-hole which is matched with the positioning column in shape is disposed on the printed circuit board, and the positioning column with non-circular cross-sectional profile passes through the through-hole and is arranged in the through-hole of the printed circuit board. Due to the fact that the cross-sectional profile of the positioning column of the fixed column is non-circular, the blocking resistance is formed when the fixed column is assembled with the printed circuit board, thus, in practical operation, the problems that the welding is not firm and the printed circuit board is easily damaged, which are caused by the releasing and slipping of the fixed column due to larger torque of electric tools and repeated installation can be effectively resolved.
Description
Technical field
The utility model belongs to LED (Light Emitting Diode, light-emitting diode) display screen technology field, relates in particular to a kind of fixed leg and has the led module of this fixed leg.
Background technology
At present, LED display is widely used, and it is mainly formed by a plurality of led module assembling combination.Each led module has pcb board (Printed Circuit Board, printed circuit board (PCB)), is welded with fixed leg on pcb board, other components and parts can be fixed on the pcb board by this fixed leg.
As shown in Figures 1 and 2, be the fixed leg structure that existing a kind of led module adopted.This fixed leg 100 has double-screw bolt 101, chassis 102 and reference column 103.Chassis 102 is positioned at an end of double-screw bolt 101, and its diameter is greater than the diameter of double-screw bolt 101, thereby 102 forms a step with the connecting portion of double-screw bolt 101 on the chassis.Reference column 103 is positioned at an end on chassis 102, is cylindric, and its diameter is less than the diameter of chassis 102 and double-screw bolt 101.On pcb board 200, offer the suitable manhole (not shown) of shape and reference column 103 shapes, the reference column 103 of fixed leg 100 inserts in the through hole of pcb board 200, chassis 102 fits in the pcb board front, and chassis 102 and part double-screw bolt 101 weld together by scolding tin as the pad on welding position 104 and the pcb board 200 201.
In practical operation, because it is that the reference column 103 of said fixing post 100 is is cylindric, the through hole on the pcb board is rounded, therefore, normal excessive or install repeatedly and make that getting loose appears in fixed leg 100 easily, skidding because of the moment of electric tool, thereby cause not prison welding solid, fragile pcb board 200.In addition, because the chassis 102 of said fixing post 100 is bigger, the welding position of therefore welding fixed leg 100 is bigger, makes the pad 201 of pcb board 200 excessive, accounts for the more area of crouching, and during welding, wastes too many scolding tin, increases cost.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of can with the firm fixed leg of assembling of pcb board.
Another technical problem to be solved in the utility model is to provide a kind of led module with said fixing post, and it can effectively solve excessive or install repeatedly and cause not prison welding solid, the problem of fragile pcb board because of the moment of electric tool.
For fixed leg of the present utility model, above-mentioned technical problem is solved like this: this fixed leg has double-screw bolt and is positioned at the reference column of double-screw bolt one end, and the cross-sectional profiles of described reference column is non-circular.
For led module of the present utility model, above-mentioned technical problem is solved like this: this led module has pcb board, on pcb board, be welded with fixed leg, described fixed leg has double-screw bolt and is positioned at the reference column of double-screw bolt one end, offer shape and the suitable through hole of reference column shape on the pcb board, reference column is arranged in the through hole of pcb board, and its cross-sectional profiles is non-circular.
Compared with prior art, because the cross-sectional profiles of the reference column of said fixing post is non-circular, therefore, itself and pcb board can produce the screens resistance when assembling, in practical operation, can effectively solve because of the moment of electric tool excessive or install repeatedly fixed leg is prone to get loose, skidding, thereby cause not prison welding solid, the problem of fragile pcb board.

Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
To shown in Figure 5, is a preferred embodiment of the present utility model as Fig. 3.This led module has pcb board 1, is welded with fixed leg 2 on pcb board 1.Described fixed leg 2 has double-screw bolt 21 and is positioned at the reference column 22 of double-screw bolt 21 1 ends, offers the suitable through hole 11 of shape and reference column 22 shapes on the pcb board 1, and the cross-sectional profiles of described reference column 22 is non-circular.When fixed leg 2 was mounted on the pcb board 1, reference column 22 was arranged in the through hole 11 of pcb board 1, and double-screw bolt 21 bottoms fit in the front of pcb board 2.Because the cross-sectional profiles of the reference column 22 of said fixing post 2 is non-circular, therefore, itself and pcb board 1 can produce the screens resistance when assembling, in practical operation, can effectively solve because of the moment of electric tool excessive or install repeatedly fixed leg 2 is prone to get loose, skidding, thereby cause not prison welding solid, the problem of fragile pcb board 1.
The shape of cross section of above-mentioned reference column 22 can be various polygons, ellipse, waist shape etc., consider from the complexity and the cost aspect of processing, the shape of cross section preferred waist shape of above-mentioned reference column 22, the shape of cross section of the reference column 22 in the present embodiment is waist shape.
In the present embodiment, the external diameter of reference column 22 is less than the diameter of double-screw bolt 21, pass the through hole 11 of pcb board 1 at reference column 22 after, fixed leg 2 and the welding position 3 of pcb board 1 are positioned at the back side of pcb board 1.Like this, can reasonably utilize the effective area of pcb board 1, significantly reduce the use of scolding tin, thereby save cost.
As the further improvement of above-mentioned execution mode, the position at contiguous pcb board 1 back side is provided with groove 23 on reference column 22, can fill up scolding tin in the described groove 23, so both can prevent to skid, and can increase the bonding area of fixed leg 2 and pcb board 1 again.
In addition, the fixed leg 2 in the present embodiment has removed chassis structure of the prior art, and the positive contact-making surface that only need vacate with the double-screw bolt 21 of fixed leg 2 of going up of pcb board 1 get final product, therefore, has increased the area of other components and parts of installation on the pcb board 1.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
