Among them, the electronic component is an electronic component that is commonly configured in combination with a circuit board, such as a MOS transistor, an IGBT transistor, or the like. The pressing member will be described in detail below.
Referring to fig. 1 to 8, in the embodiment of the present invention, the pressing member 10 includes a main body 100 and a positioning column 200; as shown in fig. 1 to 6, the positioning column 200 is disposed on the main body 100, the circuit board 20 is provided with a positioning hole 21, the positioning column 200 is configured to pass through the positioning hole 21 to be sleeved by the circuit board 20, and one end of the positioning column 200 away from the main body 100 is provided with a limiting portion 230 for preventing the circuit board 20 from coming off from the positioning column 200.

Referring to fig. 1 to 5, the electronic component 30 is disposed on a side of the main body 100 away from the circuit board 20, and the main body 100 is connected to the heat dissipation device 40, so as to press the electronic component 30 against the heat dissipation device 40. The heat dissipation device 40 may be a heat sink 42, or a combination structure of a heat dissipation member 41 (e.g., a ceramic sheet, a mica sheet, etc.) and the heat sink 42, so as to sufficiently absorb heat emitted from the electronic component 30 and cool the electronic component 30.
It can be understood that since the electronic component 30 is pressed against the heat sink 40, the electronic component 30 is fixed, and during the transportation process, the circuit board 20 is vibrated to generate displacement, thereby generating a pulling force on the pins of the electronic component 30, and when the pulling force is large, the pins are easily bent. By arranging the positioning column 200 to penetrate through the positioning hole 21 of the circuit board 20, the circuit board 20 is positioned on the main body 100, so that the circuit board 20 can be prevented from vibrating to generate large displacement in the horizontal direction, and the pins of the electronic element 30 connected with the circuit board 20 are prevented from deforming.
The shape of the positioning hole 21 on the circuit board 20 corresponds to the cross-sectional shape of the positioning column 200, and it can be understood that the size of the positioning hole 21 is slightly larger than the cross-sectional size of the positioning column 200, so that the positioning column 200 can smoothly pass through the circuit board 20. The shape of the positioning column 200 may be circular, oval, square, triangular, polygonal, or other regular shapes, and the shape of the positioning column 200 is not limited herein.
Referring to fig. 5 and 6, a limiting portion 230 is further disposed at an end of the positioning post 200 away from the main body 100, and in the transferring process, when the circuit board 20 is subjected to a large shock and moves upward along the positioning post 200, the limiting portion 230 blocks the upward movement of the circuit board 20, so as to prevent the circuit board 20 from being separated from the positioning post 200, thereby further preventing the pins of the electronic component 30 from being deformed or even broken, and protecting the circuit board 20 and the electronic component 30. Moreover, by arranging the limiting part 230, the design height of the positioning column 200 can be reduced, interference with other parts in the later-stage overall assembly process is avoided, and later-stage assembly is facilitated.
It is understood that before the positioning post 200 passes through the positioning hole 21 of the circuit board 20, the circuit board 20 is tilted to a certain angle so that the position-limiting portion 230 can pass through. The shape of the position-limiting portion 230 may be various, for example, it may be circular, square, etc., and the shape of the position-limiting portion 230 is not limited herein.
According to the technical scheme, the positioning column 200 is arranged on the main body 100, the positioning column 200 is used for penetrating through the positioning hole 21 of the circuit board 20 so as to be sleeved with the circuit board 20, the positioning column 200 can play a positioning role on the circuit board 20, the circuit board 20 is prevented from generating large displacement in the transferring process to pull the pin of the electronic element 30, and the pin of the electronic element 30 is prevented from deforming; the limiting part 230 is further arranged at one end of the positioning column 200 far away from the main body 100, and the limiting part 230 blocks the upward movement of the circuit board 20, so that the circuit board 20 can be prevented from falling off from the positioning column 200 due to vibration, the pins of the electronic element 30 are further prevented from being deformed or even broken, and the circuit board 20 and the electronic element 30 can be protected at the same time.
It can be understood that, in an embodiment, since the overall strength of the circuit board 20 is low, the positioning hole 21 is circular to prevent the circuit board 20 from cracking, and thus the positioning column 200 is also cylindrical correspondingly, and the circular positioning column 200 cannot completely position the circuit board 20 and cannot limit the degree of freedom of rotation of the circuit board 20, in order to further stably position the circuit board 20 on the positioning column 200, in this embodiment, referring to fig. 2, 5 and 6, a clamping groove 22 communicating with the positioning hole 21 is provided on the circuit board 20, a clamping portion 220 is provided on the outer peripheral wall of the positioning column 200, and the clamping portion 220 is installed in the clamping groove 22 to limit the rotation of the circuit board 20. Thus, the circuit board 20 can be stably positioned on the positioning column 200, and the circuit board 20 is not displaced and rotated even if being vibrated during the transferring process, so as to prevent the pins of the electronic component 30 from being deformed.
A plurality of positioning portions 220 may be provided, and certainly, the number of the positioning portions 220 is not too large in consideration of convenience in processing and installation, the number of the positioning portions 220 may be 1 to 4, in this embodiment, two positioning portions 220 are provided as an example, and as shown in fig. 6, the two positioning portions 220 are relatively provided on the outer peripheral wall of the positioning column 200.
The shape of the locking portion 220 can be varied, and it is understood that, also in view of the overall strength of the circuit board 20, in order to prevent the circuit board 20 from cracking, the locking portion 220 of the present embodiment is preferably in an arc shape or a shape with an arc transition.

It can be understood that the circuit board 20 can be conveniently sleeved on the positioning column 200 by disposing the limiting portion 230 on the positioning portion 220 in a protruding manner, rather than directly on the outer peripheral wall of the positioning column 200; moreover, the positioning column 200 can be conveniently integrally processed, the mold design is simplified, and the production cost is reduced.
It can be understood that the distance that the position-limiting portion 230 protrudes from the card-receiving portion 220 is greater than the distance between the card-receiving portion 220 and the inner sidewall of the card-receiving slot, so as to ensure that the circuit board 20 cannot be separated from the positioning post 200 when the circuit board is vibrated. Of course, the distance between the position-limiting portion 230 and the positioning portion 220 is not too large, so that the positioning post 200 can pass through the positioning hole 21 by slightly tilting the circuit board 20.
Further, in an embodiment, referring to fig. 5 and 6, the main body 100 is further provided with a supporting portion 300, the supporting portion 300 is provided at a side of the main body 100 close to the positioning column 200, and the supporting portion 300 is used for supporting the circuit board 20.
It can be understood that, since the pins of the electronic element 30 are soldered on the circuit board 20, the distance between the circuit board 20 and the electronic element 30 is constant, so that the circuit board 20 is not in direct contact with the main body 100, a certain gap exists between the circuit board 20 and the main body 100, and the positioning column 200 only has a positioning effect on the circuit board 20, that is, most of the weight of the circuit board 20 acts on the pins of the electronic element 30, in this embodiment, the supporting portion 300 is disposed on the main body 100 for supporting the circuit board 20, so that the supporting portion 300 can share the gravity of the circuit board 20, thereby preventing the pins of the electronic element 30 from being bent by the circuit board 20.
The supporting portion 300 may be a column or a block, and the shape of the supporting portion 300 may be a circle or a square. In the present embodiment, the supporting part 300 is provided in a column shape as an example, and in order to reinforce the supporting function of the supporting part 300, the supporting part 300 extends in the width direction of the main body 100, as shown in fig. 6. It is understood that the supporting portion 300 may be provided in plurality.
Further, in an embodiment, a distance between the supporting portion 300 and the limiting portion 230 along the height direction of the positioning column 200 is greater than the thickness of the circuit board 20.
It can be understood that, since the circuit board 20 is tilted to a certain angle to be sleeved on the positioning column 200, in order to avoid the supporting portion 300 interfering with the sleeving of the circuit board 20, the distance between the supporting portion 300 and the limiting portion 230 is greater than the thickness of the circuit board 20 along the height direction of the positioning column 200, so as to provide a movable space for the circuit board 20, and facilitate the insertion of the positioning column 200 into the positioning hole 21 of the circuit board 20.
The present invention further provides a circuit assembly, which includes a circuit board 20, an electronic component 30, and a pressing member 10, and the specific structure of the pressing member 10 refers to the above embodiments, and since the circuit assembly adopts all technical solutions of all the above embodiments, the circuit assembly at least has all beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated herein. The circuit board 20 is sleeved on the positioning column 200 of the pressing member 10, the electronic element 30 is arranged on one side of the main body 100 of the pressing member 10 away from the circuit board 20, pins of the electronic element 30 are welded with the circuit board 20, and the pressing member 10 is connected with the heat dissipation device 40 so as to press the electronic element 30 on the heat dissipation device 40.
It can be understood that, in order to firmly press the electronic component 30 onto the heat dissipation device 40, the positioning column 200 is provided with a positioning hole 21 penetrating through the main body 100, and the pressing member 10 is fixed onto the heat dissipation device 40 by inserting the fastener 50 into the positioning hole 21. The fastener 50 may be a pin or a screw.
It can be understood that, by providing the positioning hole 21 for the fastener 50 to pass through in the positioning column 200, on one hand, it is possible to avoid installing the fastener 50 in the other part of the main body 100, and prevent the fastener 50 from interfering with the circuit board 20; on the other hand, the positioning column 200 is hollow, which can reduce the waste of materials, and the fastening member 50 is hidden in the positioning column 200, which can increase the aesthetic effect.
Further, referring to fig. 5, in an embodiment, the fastening member 50 is a locking screw, the positioning hole 21 is a stepped hole, the positioning hole 21 includes a first hole portion 211 and a second hole portion 212, an inner side wall of the second hole portion 212 is provided with a positioning groove 213, and the positioning groove 213 extends along a depth direction of the second hole portion 212.
The fastener 50 is preferably a locking screw, so that compared with a pin, the design precision can be reduced, and the processing of the positioning hole 21 is facilitated; and the locking screw can be installed and dismantled fast, makes things convenient for later maintenance. As shown in fig. 5, the screw portion of the lock screw is inserted into the first hole portion 211 and screwed to the heat sink 40, and the nut of the lock screw abuts against the step surface between the first hole portion 211 and the second hole portion 212.

It should be noted that the positioning groove 213 extends to a preset position along the depth direction of the second hole portion 212, so that the distance from the bottom wall of the positioning groove 213 to the step surface is just the height of the nut of the locking screw, as shown in fig. 5, in the process of installing the locking screw by an installer, the position of the locking screw is observed through the positioning groove 213, and when the upper surface of the nut of the locking screw is flush with the bottom wall of the positioning groove 213, it indicates that the locking screw is screwed in place. The positioning groove 213 may be semicircular or square.
Further, in an embodiment, referring to fig. 6, the positioning groove 213 is disposed on the inner sidewall of the second hole portion 212 in a direction toward the positioning portion 220. It can be understood that, by opening the position of the positioning groove 213 corresponding to the positioning portion 220 on the inner side wall of the first hole portion 211, the wall thickness of the positioning column 200 can be further reduced, and the waste of material can be avoided.
Further, in an embodiment, in order to enable the pressing member 10 to stably press the electronic component 30 onto the heat dissipation device 40, a limiting groove 110 is disposed on a side of the main body 100 away from the circuit board 20, and the electronic component 30 is received in the limiting groove 110.

The shape of the limiting groove 110 corresponds to the shape of the electronic element 30, and the limiting groove 110 limits the electronic element 30, so that the pins can be prevented from being deformed due to the fact that the electronic element 30 moves left and right when being pressed by the main body 100, and meanwhile, the electronic element 30 can be prevented from being vibrated to generate displacement in the transferring process.
Further, in an embodiment, the first abutting portion 120 is formed at the bottom of the limiting groove 110 for abutting against the electronic component 30. The shape of the first abutting portion 120 may be a column, a block, or a bar, and the shape of the first abutting portion 120 is not limited herein.
It can be understood that, since the main body 100 is connected to the heat dissipation device 40 only through the fastening member 50, and the fastening member is connected to one side of the main body 100, the force applied to the side of the main body 100 close to the fastening member is relatively large, and the force applied to the side far from the fastening member is relatively small, the main body 100 is easy to incline towards one side, so that the groove bottom of the limiting groove 110 cannot be completely contacted with the electronic element 30, a gap exists between the limiting groove 110 and the electronic element, so that the electronic element cannot be pressed, and even the electronic element 30 can be drawn out from the limiting groove 110 under the action of external force, by convexly arranging the first abutting portion 120 at the groove bottom of the limiting groove 110, the first abutting portion 120 abuts against the electronic element, the contact area between the electronic element and the pressing member can be reduced, the pressure can be increased, and the electronic element can be stably pressed on the heat dissipation device 40. Furthermore, by pressing the electronic component by the first abutting portion 120, instead of pressing the electronic component by the groove bottom of the stopper groove 110, the machining dimensional accuracy, the positional accuracy, and the surface finish of the groove bottom of the stopper groove 110 can be reduced, the machining difficulty thereof can be reduced, and the cost can be reduced.
