Description
Technical Field
[0001] This utility model relates to the field of electrical equipment technology, and in particular to a port protection structure for frequency converter components. Background Technology
[0002] The inverter is a key component of a frequency conversion system. Its main function is to convert direct current (DC) to alternating current (AC). The inverter mainly relies on power electronic devices to achieve this conversion. The port on the inverter is used to connect to DC power. The parameters of this port are designed to match the DC power supply. It determines its specifications based on the voltage range and current capacity of the DC power supply. When the connection cable is inserted into the DC input port, the power from the external DC power supply can be delivered to the inverter. However, there is no protection for the connection after it is inserted into the port. After prolonged use, one end of the connection cable may break. When the connection cable breaks, it may cause the DC input to be interrupted or the AC output to stop. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0028] Example 1
[0029] Reference Figures 2-6This is the first embodiment of the present utility model. This embodiment provides a protection structure for the port of a frequency converter component. The protection structure for the port of a frequency converter component includes a shielding component 200, a protection component 300, and a main component 100. The three components work together to protect one end of the connecting line.
[0030] The shielding assembly 200 includes a shielding member 201, which includes a shielding plate 201a, a slider 201b, and a first spring 201c. The slider 201b is fixed to one side of the shielding plate 201a, and the first spring 201c is fixed to the bottom of the slider 201b.
[0031] When the inverter 101 is not in use, the port 102 can be protected by closing the shield 201a to prevent dust from accumulating inside the port 102. When it is necessary to insert the connecting cable 103 into the port 102, the shield 201a is moved, and the slider 201b is located inside the inverter 101. The slider 201b slides inside the inverter 101, and the first spring 201c is fixed to the inner wall of the inverter 101. The movement of the shield 201a drives the slider 201b to move. The movement of the slider 201b can apply a pulling force to the first spring 201c. After the shield 201a is opened, the connecting cable 103 can be inserted into the port 102. When the connecting cable 103 is taken out of the port 102, the rebound force of the first spring 201c can drive the shield 201a back to its original position, thereby protecting the port 102.
[0032] The protective component 300 is disposed on one side of the shield 201 and includes a protective plate 301a, a movable strip 301b and a hinge rod 301c. The protective plate 301a is disposed on one side of the shield 201a, the movable strip 301b is fixed to the top of the protective plate 301a, and the hinge rod 301c is hinged to one end of the movable strip 301b.
[0033] There are two protective plates 301a, which are respectively set on both sides of the connecting line 103. There are two moving bars 301b, both fixed to the top of the protective plate 301a. There are two hinge rods 301c, both hinged to the moving bars 301b. When it is necessary to protect the connecting line 103, the connecting line 103 is inserted into the port 102. By moving the hinge rods 301c, the hinge rods 301c drive the moving bars 301b to move, and the moving bars 301b drive the protective plates 301a to move. By moving the hinge rods 301c, the protective plates 301a can be engaged with the connecting line 103, thereby protecting the connecting line 103.
[0034] Example 2
[0035] Reference Figures 2-6 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0036] Specifically, the shielding assembly 200 also includes a support member 202, which is disposed on the shielding plate 201a, and a handle 202a is fixed to the top of the shielding plate 201a.
[0037] When it is necessary to move the baffle 201a, the baffle 201a can be moved by pulling the handle 202a. Then, in order to prevent the force of the first spring 201c from rebounding, the baffle 201a can be moved back to its original position by limiting the handle 202a.
[0038] Specifically, a positioning block 202b is provided on one side of the handle 202a, and a second spring 202c is fixed on one side of the positioning block 202b.
[0039] The handle 202a can be limited by the positioning block 202b. The positioning block 202b is inserted into one side of the inverter 101 and is movably connected to the inverter 101. There are two second springs 202c, both of which are fixed to one side of the positioning block 202b. When it is necessary to release the limitation of the handle 202a, the positioning block 202b is pressed. At this time, the second spring 202c can be squeezed. Then the handle 202a is moved to the top of the positioning block 202b. After that, the positioning block 202b is released. The rebound force of the second spring 202c can drive the positioning block 202b back to its original position.
[0040] Specifically, the bottom of the positioning block 202b is set as an arc surface, and a support plate 202d is fixed on one side of the second spring 202c.
[0041] When the handle 202a is moved to the bottom of the positioning block 202b, the handle 202a can press the arc surface at the bottom of the positioning block 202b, thereby causing the positioning block 202b to move. After the handle 202a is moved to the top of the positioning block 202b, the rebound force of the second spring 202c can drive the positioning block 202b back to its original position. There are two support plates 202d, both of which are fixed to the inner wall of the inverter 101. The support plates 202d can support the second spring 202c and prevent the second spring 202c from shifting.
[0042] Specifically, the protective component 300 also includes a connector 302, which is disposed on the hinge rod 301c. A support column 302a is inserted into one side of the hinge rod 301c, and the support column 302a and the hinge rod 301c are hinged together.
[0043] There are two support columns 302a, both of which are fixed on one side of the inverter 101. The support columns 302a can support the hinge rod 301c and prevent the hinge rod 301c from shifting when moving.
[0044] Specifically, a drive rod 302b is provided at one end of the hinge rod 301c, and the drive rod 302b and the hinge rod 301c are hinged together. A turntable 302c is provided on one side of the drive rod 302b, and the turntable 302c and the drive rod 302b are hinged together.
[0045] There are two drive rods 302b, both of which are hinged to one end of the hinge rod 301c. By rotating the turntable 302c, the drive rods 302b are moved, and the movement of the drive rods 302b can drive the hinge rod 301c to move.
[0046] Specifically, a torsion spring 302d is fixed on one side of the turntable 302c, a limit block 302e is provided on one side of the turntable 302c, and a pull rod 302f is fixed on one side of the limit block 302e.
[0047] A limiting groove corresponding to the limiting block 302e is provided on one side of the turntable 302c. By engaging the limiting block 302e with the limiting groove, the turntable 302c can be limited. When it is necessary to release the limitation on the turntable 302c, the pull rod 302f is pulled. The pull rod 302f causes the limiting block 302e to separate from the turntable 302c, thus releasing the limitation on the turntable 302c. Then the turntable 302c can be rotated. When rotating, a torsional force can be applied to the torsion spring 302d. The torsion spring 302d is fixed to one side of the frequency converter 101. When the turntable 302c is rotated, the protective plate 301a can be driven to protect one end of the connecting wire 103. At this time, in order to prevent the force of the torsion spring 302d from rotating and causing the turntable 302c to return to its original position, the pull rod 302f is released. The return of the pull rod 302f to its original position can drive the limit block 302e to engage with the limit groove, thereby limiting the turntable 302c.
[0048] Example 3
[0049] Reference Figures 1-6 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0050] Specifically, a pressure plate 302g is sleeved on the outside of the pull rod 302f, a third spring 302h is fixed on one side of the pressure plate 302g, and a support sleeve 302i is sleeved on the outside of the pull rod 302f, and the support sleeve 302i and the pull rod 302f are movably connected.
[0051] When the pull rod 302f moves, it can drive the pressure plate 302g to move. The movement of the pressure plate 302g can apply a squeezing force to the third spring 302h. When the pull rod 302f is released, the rebound force of the third spring 302h can drive the pull rod 302f back to its original position. The support sleeve 302i is fixed to one side of the inverter 101. The support sleeve 302i can support the pull rod 302f and prevent the pull rod 302f from shifting.
[0052] Specifically, it also includes a main component 100, which is disposed on the shield 201a, including a frequency converter 101 and a port 102. The frequency converter 101 is sleeved on the outside of the shield 201a, and the frequency converter 101 and the shield 201a are movably connected. The port 102 is fixed to one side of the frequency converter 101.
[0053] The inverter 101 can convert DC power to AC power. The inverter 101 mainly relies on power electronic devices to realize the DC to AC power conversion. The port 102 set on the inverter 101 is used to connect DC power. The parameters of this port 102 are designed to match the DC power supply. The port 102 will determine its own specifications according to the voltage range, current capacity, etc. of the DC power supply. When the connecting wire 103 is inserted into the DC input port, the power of the external DC power supply can be delivered to the inverter.
[0054] Specifically, a connecting cable 103 is installed inside port 102.
[0055] The connecting line 103 is mainly used to establish a physical connection between the external DC power supply and the DC input port 102 of the frequency converter 101, and plays the role of transmitting electrical energy, so that the external DC power can smoothly enter the inside of the frequency converter to supply the frequency converter 101 to perform DC to AC conversion.
[0056] When the inverter 101 is not in use, the port 102 can be protected by closing the shield 201a to prevent dust from getting into the port 102. When the connecting cable 103 needs to be inserted into the port 102, the handle 202a is moved, which moves the shield 201a. At this time, the movement of the shield 201a moves the slider 201b. The movement of the slider 201b can apply a pulling force to the first spring 201c. When the handle 202a is moved to the bottom of the positioning block 202b, the handle 202a can squeeze the arc surface at the bottom of the positioning block 202b, thereby moving the positioning block 202b. The movement of the positioning block 202b can apply a squeezing force to the second spring 202c. Then, when the handle 202a is moved to the top of the positioning block 202b, the rebound force of the second spring 202c can drive the positioning block 202b back to its original position, thereby limiting the handle 202a.
[0057] Then, the pull rod 302f is moved. When the pull rod 302f moves, it drives the pressure plate 302g to move. The movement of the pressure plate 302g applies a compressive force to the third spring 302h. The pull rod 302f causes the limiting block 302e to separate from the turntable 302c, thus releasing the limiting effect on the turntable 302c. Then, the turntable 302c is rotated. When the turntable 302c rotates, it applies a torsional force to the torsion spring 302d. Rotating the turntable 302c... The drive rod 302b can be moved, which in turn moves the hinge rod 301c. The hinge rod 301c moves the moving bar 301b, which in turn moves the protective plate 301a, causing the protective plate 301a to engage with the connecting line 103, thus protecting the connecting line 103. Then, the pull rod 302f is released, and the rebound force of the third spring 302h can drive the pull rod 302f back to its original position to limit the turntable 302c.
[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
