As shown in Figure 2, several nuts 3 are welded on a plate 31 and place the back side of motherboard 2, and several screw rods 4 pass a heating radiator 5 ' and motherboard 2 in regular turn, screw togather with each nut 3 respectively again, make this heating radiator 5 ' be fixed on the motherboard 2.The heavier element though above-mentioned design can be loaded, as heating radiator 5 ' etc., but the material cost of making web joint 31 and nut 3 is higher, and the part back side of motherboard 2 is covered by this web joint 31, will increase the complexity of motherboard 2 processing, be unfavorable for the manufacturing of motherboard 2.
Summary of the invention
Therefore, the purpose of this utility model is to provide a kind of circuit board with component-fixing device, effectively the element that fixed weight is heavier and can not increase the cost of manufacturing and the complexity of processing.
According to the utility model, a kind of circuit board with component-fixing device is applicable to and fixes an element that this circuit board includes a substrate and a stationary installation.
Be formed with a perforate on this substrate.One weld pad is arranged on the back side and contiguous this perforate of this substrate.This stationary installation includes a fixture and a screw rod.This fixture has the connecting portion that a size is protruded out by a side direction of this base portion greater than the base portion of this perforate and outward.The welding of this base portion and this weld pad, and this connecting portion is placed among this perforate and do not protrude from the front of this substrate, is formed with the screw that is communicated with the front of this substrate in this base portion and this connecting portion.This screw rod can pass this element and with the screwhole spiro bonding of this fixture, thereby this element is fixed on this substrate.
Aforementioned and other technology contents, characteristics and effect of the present utility model in the preferred embodiment of describing in detail below in conjunction with accompanying drawing, can clearly present.

Figure 4 shows that the sectional perspective combination synoptic diagram of this preferred embodiment;
Figure 5 shows that the cross sectional side view on the circuit board that provides in this preferred embodiment is provided an element.
Embodiment
To shown in Figure 5, in preferred embodiment of the present utility model, the circuit board 1 with component-fixing device is applicable to fixes an element 6 as Fig. 3.In this embodiment, circuit board 1 is to be example with a motherboard, and element 6 for example is a heating radiator, but it does not exceed with each illustration.This circuit board 1 includes a substrate 11 and several stationary installations 12, and this substrate 11 for example is the printed circuit board (PCB) of using always, and in other embodiment of the present utility model, the minimum number of stationary installation 12 can be one.
Be formed with several perforates 111 on this substrate 11, and several pieces weld pads 112 are arranged on the back side of this substrate 11 and are respectively adjacent to each perforate 111 and ground connection.
Each stationary installation 12 corresponding perforate 111, it includes a fixture 121 and a screw rod 122.Fixture 121 has a base portion 123 and a junction 124, this base portion 123 is a right cylinder, the size of its end face is greater than this perforate 111, and this connecting portion 124 is right cylinders that the coaxial heart of an end face by this base portion 123 extends upward, the size of the end face 127 of this connecting portion 124 can match with this perforate 111, so is formed with a contact plane 126 around this connecting portion 124 on the end face of this base portion 123 near this connecting portion 124.And in this fixture 121, be formed with along this axle center and pass this connecting portion 124 and this base portion 123 is communicated with up and down and the screw 125 that can be screwed with this screw rod 122.
The connecting portion 124 of each fixture 121 is placed among the wherein perforate 111, and the contact plane on this base portion 123 126 connects fixing with the weld pad 112 of contiguous this perforate 111 with soldering, and make and to make that so fixture 121 can not convexedly stretch in outside the front of this substrate 11 by this connecting portion 124 positive concordant away from the end face 127 of this base portion 123 and this substrate 11.
