Description

Technical Field

[0001] The present invention relates to the technical field of power electronic components, and more particularly to power electronic components of embedded power electronic equipment. Background Art

[0002] Power electronic equipment is equipment with power electronic devices as main functional components, mainly used in power conversion and control circuits. Therefore, when power electronic equipment is assembled with related facilities, it needs to be combined with supporting power electronic components to achieve a stable embedding connection effect. Power electronic components can ensure that power electronic equipment can be stably installed and used in the facilities, preventing damage caused by direct contact between precision areas and metal surfaces, so as to effectively improve the stability of power electronic equipment. In summary, the inventors have found that the existing power electronic components mainly have the following defects: since the current power electronic components need to be locked one by one at the four corners by manual bolts when they are embedded in the matching power electronic equipment in parallel, and when one corner is tightened under force while being locked one by one, the other three corners will be slightly offset due to the lack of fixing force, so it will be difficult to accurately align the power electronic component with the center of the power electronic equipment, which will affect the stability of the subsequent overall power-on operation, thereby reducing the embedded assembly strength of the current power electronic components. Summary of the invention

[0003] The technical solution adopted by the present invention to achieve the technical purpose is: a power electronic component of an embedded power electronic device, whose structure includes: a connector, a loading slot, an electronic chip, an insertion rod, and a protective cover. The electronic chip is loaded into the connector through the loading slot and then the insertion rod of the upper protective cover is embedded into the upper edge of the connector so that the protective cover covers the top of the electronic chip.

[0004] As a further improvement of the present invention, the connecting piece is provided with an anti-bias structure, which is embedded in the inner center of the shell and has a spacing corner with the shell to form a vertical sleeve, and an adsorption block is also carried inside the vertical sleeve. The center of the lower end of the shell is connected to a central block and the left and right sides are equipped with power-on plugs to horizontally penetrate the adsorption block and electrically connect it to the electronic chip inside the anti-bias structure.

[0005] As a further improvement of the present invention, the anti-bias structure is provided with a pressing block, which is arranged in the outer area of ​​the limit frame and contacts the vertical sleeve edge on the left and right sides. A positioning plate is mounted inside the limit frame to overlap with the bottom layer of the electronic chip.

[0006] As a further improvement of the present invention, the anti-bias structure is installed vertically and parallely through the center block at the bottom of the outer shell of the connector, and then the insertion rods of the vertical sleeve and the protective cover are aligned and interlaced, so that the pressing block of the anti-bias structure presses the edge of the entire connector with weight, and the position of the electronic chip is determined by the positioning plate inside the limit frame.

[0007] As a further improvement of the present invention, the loading slot inside the connector is opened in a vertical parallel orientation to allow the electronic chips to be arranged in a parallel orientation, and then the four corners at the lower end of the protective cover carry four solid plugs that restrain the four corners of the connector.

[0008] As a further improvement of the present invention, the center block is perpendicular to the center of the lower end of the shell and the anti-bias structure inside the shell is rectangular in shape to allow the electronic chips to be arranged in parallel. A square slot is opened inside the vertical sleeve to allow the insertion rod to be inserted and is set in the four corners of the inner wall of the shell.

[0009] As a further improvement of the present invention, the pressing block is in a solid rectangular shape and two are provided on the outer edge of the limiting frame, and the shape of the positioning plate is consistent with the shape of the electronic chip.

[0010] As a further improvement of the present invention, the pressing block is provided with a vertical plug-in, which is fixed to the left and right sides of the block and the lower end of the block is connected to a magnetic plate to overlap with the bottom layer inside the shell. A threaded groove is also opened on the surface of the block to allow the bolts to be vertically locked into the shell for detachable connection.

[0011] As a further improvement of the present invention, the vertical plug-in is in a "T" shape and is provided with a group on each of the left and right sides of the block in a symmetrical orientation, and the length of the magnetic attraction plate matches the length of the bottom of the block.

[0012] As a further improvement of the present invention, the vertical plug-in is provided with a slider, the slider is connected to the outer center of the plate body, and an assembly groove is opened in the center of the surface layer of the plate body to allow the card block to be embedded.

[0013] As a further improvement of the present invention, the plate body is inserted and connected with the center of the edge of the vertical sleeve through a slider, and then the assembly groove of the plate body is combined with the clamping block to be clamped and connected with the side of the block.

[0014] As a further improvement of the present invention, the protective cover is provided with a central protective plate, which is embedded in the central part of the cover plate and its edge overlaps with the upper edge of the limiting frame, so that the distance between the central protective plate and the cover plate forms a cavity for the upper end of the pressing block to be embedded, and a cross bar is also connected to the center of the central protective plate to position the constant temperature body.

[0015] As a further improvement of the present invention, the cover plate is rectangular in shape and matches the shape of the overall connecting piece and a plug rod is fixed at each of the four corners. The central protection plate is vertically arranged at the center of the cover plate, the center of the side of the thermostat is restrained by a cross bar, and the shape of the thermostat matches the shape of the electronic chip and the positioning plate.

[0016] As a further improvement of the present invention, the central protective plate is provided with a connecting buckle, which is installed on the edge of the parallel plate and the upper end of the parallel plate is covered with an insulating plate. The power-carrying plug in the center of the insulating plate passes through the insulating plate, the center of the parallel plate and is electrically connected to the internal constant temperature body.

[0017] As a further improvement of the present invention, the connecting buckles are set in symmetrical positions on the left and right sides of the parallel plate and the top of the constant temperature body can be fixed inside the parallel plate, and then electrically connected through the power plug-in of the insulating plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is further improved by the connecting piece. The central block at the lower end of the shell is used to install the whole device at the central connecting part of the device. Then, the limit frame and the pressing block of the anti-bias structure are used to install the whole electronic component in parallel. The weight pressing of the pressing block, the center restraint of the central block and the insertion and fixing of the power-on plug block can ensure that the electronic chip of the power electronic component is accurately installed in parallel in the center area of ​​the device, replacing the original bolts that lock the four corners one by one to produce the center point deviation caused by uneven force on the corners, thereby improving the overall power electronic component to be electrically connected to the device through parallel embedding.

[0019] 2. The present invention is further improved on the pressing block. The plate body and the slider of the vertical plug-in can effectively intersect and connect with the center of the outer edge of the vertical sleeve, thereby improving the accuracy of the solid block falling into the distance between the outer shell and the limit frame. The threaded grooves provided on the block can allow the bolts to be locked in, thereby improving the overall firmness of the pressing block in the power electronic assembly and avoiding abnormal noise caused by continuous impact caused by unstable vibrations generated during facility operation.

[0020] 3. The present invention is further improved by the protective cover. The top of the pressing block can be embedded through the cavity of the cover plate and the central protective plate, so as to prevent the protective cover as a whole from being unable to seal the electronic chip due to the addition of the pressing block. At the same time, the constant temperature body of the central protective plate can overlap with the upper layer of the electronic chip. Therefore, when the electronic chip is electrically connected to the facility through the power-on plug-in, the constant temperature body uses the upper power-on plug-in to connect with other power-on circuits to achieve a joint operation effect, thereby balancing the temperature of the electronic chip and avoiding damage caused by high temperature generated by continuous operation.
