Here; because the hypomere 242 of the second boss 24 stretches out in the second pilot hole 12; therefore when the second connector 6 is installed; second connector 6 can directly stretch in the second boss 24; collide with the lower end and circuit board 1 of avoiding the second connector 6, reach protective circuit plate 1, improve the effect of the unfailing performance of circuit board assemblies 100.
To sum up, have employed two kinds of fixed forms between circuit board 1, support 2, chip 3 and radiator 4, a kind of fixed form is employing first connector 5 and coordinates the structure of the first boss 23, so that circuit board 1, support 2 and radiator 4 are completely fixed connection.
Another kind of fixed form is employing second connector 6 and coordinates the structure of the second boss 24, both locates circuit board 1, and is fixed between support 2 and radiator 4 by multiple chip 3 again.
Here it should be noted that, as shown in Figure 8, chip 3 is provided with pin 31, and the pin 31 of chip 3 is welded and fixed on circuit board 1 usually.Second connector 6 is non-connecting circuit board 1 when fixed chip 3, avoid circuit board 1 and be connected tension with chip 3, thus the pin 31 avoiding chip 3 and the pad place of circuit board 1 are stressed excessive and damage, and then ensure the quality of connection between chip 3 and circuit board 1.In addition, be closely beneficial to dispel the heat for ensureing that chip 3 is connected with radiator 4, the second connector 6 usually needs is tightlyer stubborn, and therefore the second connector 6 does not connect the destruction can avoided on the circuit card 1 circuit board 1.Thus, adopt the second connector 6 and coordinate the structure of the second boss 24, the installation simultaneously completing chip 3 is fixed and protective effect.
Thus, being combined of above-mentioned two kinds of fixed forms, makes circuit board 1, support 2, chip 3 and radiator 4 be connected firmly, reliably, circuit board assemblies 100 fitting operation is simple, fixing reliably, stability is high.And can protect IC 3; make that chip 3 is fixed, contact stabilization; thus ensure that chip 3 is close on radiator 4 all the time; to ensure that chip 3 dispels the heat to greatest extent; make circuit board assemblies 100 under various severe hot environment during operation; chip 3 all can dispel the heat well, and then effectively reduces the failure rate of chip 3, greatly improves the reliability of circuit board assemblies 100.
Alternatively, the lower end of the second connector 6 is only against on the lower surface of support 2, that is, the Internal periphery size of the cross section of the second boss 24 is greater than the lower end projection size in the horizontal plane of the second connector 6, thus the lower end of the second connector 6 is directly only against on the lower surface of support 2.Thus, the second connector 6 size in the vertical direction can shorten, thus avoids the second connector 6 to bend impaired, and then improves the reliability of the second connector 6 connection.
According to the electric-controlled box assembly 1000 of the utility model embodiment; by arranging the support 2 with the first boss 23 and the second boss 24; both the connection of each components and parts of realizing circuit board component 100 was reliable; again can protect IC 3; make that chip 3 is fixed, contact stabilization; and can ensure that chip 3 dispels the heat to greatest extent, make circuit board assemblies 100 under various severe hot environment during operation, chip 3 all can dispel the heat well.By arranging the first fixture 300 and the second fixture 400, and coordinating the first button bit 231 and the second button bit 232, thus circuit board assemblies 100 to be directly fixed on automatically controlled lid 200, such that electric-controlled box assembly 1000 assembles simply, efficiency is high.
