Description

Technical Field

[0001] This invention relates to the field of inverter structure technology, and more specifically to an external memory card structure used in inverters. Background Technology

[0002] An inverter is a converter that transforms direct current (DC) power into alternating current (AC) power with fixed frequency and voltage or adjustable frequency and voltage. It consists of an inverter bridge, control logic, and filter circuits. Inverters are widely used in various fields of life, and with the increasing emphasis on new energy sources, they are also widely used in the photovoltaic (PV) new energy field.

[0003] In the current photovoltaic new energy field, the data collection module of the inverter is basically achieved by pre-programming software onto the PCBA board, with the programming interface pre-placed on the PCBA board. This method has the drawback of making software upgrades difficult. Therefore, pre-writing the software onto a memory card and inserting the memory card into the interface is another option. However, existing interfaces are located on the enclosure, and inserting the memory card can cause it to fall into the enclosure. To prevent this, the entire inverter casing usually needs to be removed for safe replacement. Since the enclosure contains many delicate wiring connections, removing the memory card can easily damage the inverter's operating environment, potentially causing inverter failure. Therefore, a solution for easily removing and installing memory cards is urgently needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide an external memory card connection structure for use in inverters, which enables convenient insertion and removal of memory cards without damaging the inverter.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An external memory card connection structure for use in an inverter, characterized in that:

[0007] It includes an external connector and an internal connector, which are respectively located on the outer side and the inner side of the housing;

[0008] A docking assembly is used to connect the inner connector to the housing.

[0009] An external component is provided, wherein the external connector and the internal connector are connected via the external component.

[0010] An expansion component is provided with a plug-in port for inserting and removing a memory card. The plug-in port is located on an external connector. The end of the expansion component away from the plug-in port is connected to an inverter located inside a housing. The housing has mounting holes for the expansion component to pass through.

[0011] As a further improvement of the present invention, the docking assembly includes a first guide and a connector, the first guide being disposed on the housing, and the inner connector being connected to the first guide via the connector.

[0012] As a further improvement of the present invention, the external component includes a locking member and a positioning member. The positioning member is disposed on the inner seat, and the locking member is disposed on the outer seat. When the locking member and the positioning member are connected, the outer seat is connected to the inner seat.

[0013] As a further improvement of the present invention, the plug-in port is provided with a mounting member, which is used to connect the plug-in port and the external socket.

[0014] As a further improvement of the present invention, a sealing element is also provided between the inner connector and the housing.

[0015] As a further improvement of the present invention, an anti-theft component is also connected between the external connector and the housing. The anti-theft component, the housing, and the external connector are respectively connected to anti-theft fixing components. The anti-theft fixing components are used to fix the anti-theft component to the external connector and the anti-theft component to the housing.

[0016] As a further improvement of the present invention, the extension component includes an extension cable and a connector, one end of the extension cable being connected to a plug-in port and the other end being connected to the connector, which is connected to the inverter.

[0017] As a further improvement of the present invention, a card ejection component is also provided in the insertion port. The card ejection component includes a card-top component, a card-pushing component, and a control component. The control component is disposed in the insertion port. The card-top component is connected to the card-pushing component and the control component. A card slot is provided on the side wall of the memory card, and the card-top component is disposed in the card slot.

[0018] As a further improvement of the present invention, the top card component includes a top pin and a pusher, the pusher component includes a pusher base and a second guide, the top pin is disposed in the card slot, the top pin is connected to the pusher base through the pusher, one end of the pusher is hinged to the top pin, the other end is hinged to the pusher base, the end of the top pin away from the one hinged to the pusher base abuts against the memory card, a pusher angle is formed between the pusher base and the top pin, and the second guide is connected to the side of the pusher base facing the direction of memory card insertion;

[0019] The control component includes an electromagnetic component and a control switch. The end of the second guide member away from the push base is inserted into the electromagnetic component. The control switch is disposed on the mounting component and is electrically connected to the electromagnetic component. When the control switch is turned on by touch, the electromagnetic component provides a magnetic attraction force to attract the second guide member, attracting the push base to move towards the electromagnetic component, so that the push member pushes the ejector pin to eject the memory card.

[0020] As a further improvement of the present invention, the control component further includes a reset elastic element, which is sleeved outside the second guide element. One end of the reset elastic element abuts against the push seat, and the other end abuts against the electromagnetic element.

[0021] The beneficial effects of this invention are as follows: By setting an inner connector and an outer connector on the inner and outer sides of the enclosure respectively, the inner connector is fixed to the enclosure by connecting and fixing it through a docking component. The outer connector is connected to the inner connector through an external component, thereby fixing the outer connector to the inner connector. One end of the expansion component is provided with a plug-in port that connects to the outer connector, and the other end is connected to the inverter. Since the outer connector and the inner connector are connected through an external component, the memory card can be easily removed and plugged in when the connection between the outer connector and the inner connector is disconnected. At this time, the inner connector remains connected to the enclosure, achieving the effect of not needing to disassemble the entire enclosure for plugging and unplugging. It also facilitates the plugging and unplugging of the memory card outside the enclosure, making it less likely for the memory card to fall into the enclosure. The external component allows for easy reinstallation of the outer connector, achieving the effect of convenient plugging and unplugging of the memory card without damaging the inverter.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0031] Example 1:

[0032] refer to Figures 1 to 3 The diagram illustrates a specific embodiment of an external memory card connection structure applied in an inverter according to the present invention. It includes an external connector 2 and an internal connector 3, which are respectively located on the outer and inner sides of a housing 1. The internal connector 3 is connected to the housing 1 via a docking assembly 4. The docking assembly 4 includes a first guide 41 and a connector 42. The first guide 41 is mounted on the housing 1 and is selected as a stud. The first guide 41 is riveted to the housing 1. The internal connector 3 is connected to the first guide 41 via a connector 42, which is selected as a nut. The internal connector 3 has a through hole for the first guide 41 to pass through. A sealing element 8 is also provided between the internal connector 3 and the housing 1. The sealing element 8 has a straight hole corresponding to the position of the first guide 41 for the first guide 41 to pass through. During installation, the straight hole on the seal 8 is inserted into the first guide 41, and then the through hole on the inner seat 3 is installed in correspondence with the first guide 41. The connector 42 is threadedly connected to the first guide 41 to realize the connection between the inner seat 3 and the housing 1, and to clamp and fix the seal 8.

[0033] refer to Figure 2 and Figure 3The external structure also includes an external component 5 and an expansion component 6. The expansion component 6 includes an expansion cable 61 and a connector 62. One end of the expansion cable 61 is connected to a plug-in port 7, and the other end is connected to the connector 62. The plug-in port 7 is used for inserting a memory card. The plug-in port 7 is located on the side of the external connector 2 facing the housing 1. The plug-in port 7 is provided with a mounting part 71, which is a screw. The mounting part 71 is used to connect and fix the plug-in port 7 to the external connector 2, so that the plug-in port 7 is not easy to move when inserting or removing the memory card. The housing 1 has a mounting hole 11 for the expansion component 6 to pass through. One end of the expansion cable 61 with the connector 62 passes through the mounting hole 11 into the housing 1 and connects to the inverter inside the housing 1. So that when a memory card is inserted at the plug-in port 7, the connection is achieved through the expansion cable 61 to the inverter. The connector 2 and the inner connector 3 are connected by an external component 5. The external component 5 includes a locking member 51 and a positioning member 52. The positioning member 52 is located on the side of the inner connector 3 away from the housing 1. The positioning member 52 is a stud and is riveted to the inner connector 3. The locking member 51 is located on the outer connector 2 and is a screw. The sealing member 8 also has a through hole for the locking member 51 to pass through. After the expansion component 6 and the inverter are installed, the outer connector 2 and the inner connector 3 are installed to achieve the effect of overall installation. During installation, the locking member 51 passes through the through hole to the positioning member 52 located on the inner connector 3 and is fixed to the outer connector 2 and the inner connector 3 by threaded connection with the positioning member 52. At this time, the insertion port 7 for the memory card is located inside the housing 1 through the mounting hole 11.

[0034] When it is necessary to remove the memory card, the connection between the locking part 51 and the positioning part 52 is released, so that the external connector 2 can be removed. This allows for easy insertion and removal of the memory card without disassembling the overall housing 1, and also prevents damage to the inverter.

[0035] refer to Figure 2 and Figure 3 An anti-theft component 9 is also connected between the external connector 2 and the enclosure 1. The anti-theft component 9 is connected to the enclosure 1 and the external connector 2 by anti-theft fasteners 91. The anti-theft fasteners 91 are screws, and the anti-theft component 9 is a steel wire rope. The anti-theft fasteners 91 are used to fix the anti-theft component 9 to the external connector 2 and to the enclosure 1, so that when the memory card needs to be inserted or removed, the external connector 2 can be pulled to separate from the enclosure 1. At this time, due to the function of the anti-theft component 9, when the anti-theft component 9 is tightened, the extension cable 61 will become loose, and it is not easy for the external connector 2 to pull the extension cable 61 to loosen the connection between the connector 62 and the inverter. This achieves the effect of preventing theft while preventing the connection between the extension component 6 and the inverter from becoming loose, thus maintaining the stable working state of the inverter.

[0036] Working principle and its effects:

[0037] By setting an inner connector 3 and an outer connector 2 on the inner and outer sides of the enclosure 1 respectively, the inner connector 3 is fixed to the enclosure 1 by connecting and fixing it through a docking component 4. The outer connector 2 is connected to the inner connector 3 through an outer component 5, thereby fixing the outer connector 2 and the inner connector 3. One end of the expansion component 6 is provided with a plug-in port 7 connected to the outer connector 2, and the other end is connected to the inverter. Since the outer connector 2 and the inner connector 3 are connected through the outer component 5, the memory card can be easily removed and plugged in when the connection between the outer connector 2 and the inner connector 3 is disconnected. At this time, the inner connector 3 remains connected to the enclosure 1, achieving the effect of not needing to disassemble the entire enclosure 1 for plugging and unplugging. It also facilitates the plugging and unplugging of the memory card outside the enclosure 1, making it less likely for the memory card to fall into the enclosure 1. The outer component 5 allows for easy reinstallation of the outer connector 2, achieving the effect of convenient plugging and unplugging of the memory card without damaging the inverter.

[0038] Example 2:

[0039] This is a specific embodiment of the present invention for an external memory card connection structure applied in an inverter, which differs from Embodiment 1 in that: (Refer to...) Figures 4 to 7The insertion / removal port is also equipped with a card ejection assembly 10, which includes a card ejector component 20, a card pusher component 30, and a control component 40. A card slot is provided on the side wall of the memory card. The card ejector component 20 includes a ejector pin 201 and a pusher component 202. The card pusher component 30 includes a pusher base 301 and a second guide component 302. The ejector pin 201 is disposed in the card slot. A guide block is provided on the mounting component, and a guide groove is provided on the guide block along the insertion / removal direction of the memory card. A slider that slides along the guide groove is provided on the side of the ejector pin 201 opposite to the memory card. One end of the pusher component 202 is hinged to the ejector pin 201, and the other end is hinged to the pusher base. 301 is hinged, and the end of the ejector pin 201 away from the hinged part 202 abuts against the memory card. A push angle is formed between the pusher 202 and the ejector pin 201. The second guide 302 is connected to the side of the push base 301 facing the direction of memory card insertion. The control component 40 includes an electromagnetic component 401, a control switch 402, and a reset elastic component 403. The electromagnetic component 401 is connected to the mounting component. The end of the second guide 302 away from the push base 301 is inserted into the electromagnetic component 401. The reset elastic component 403 is selected as a spring and is sleeved on the second guide 302. One end of the reset elastic element 403 abuts against the push base 301, and the other end abuts against the electromagnetic element 401. The control switch 402 is mounted on the mounting piece and is electrically connected to the electromagnetic element 401. When the touch control switch 402 is turned on, the electromagnetic element 401 generates a magnetic attraction force that pulls the second guide element 302 toward the direction of the electromagnetic element 401. At this time, the movement direction of the second guide element 302 is consistent with the direction of the memory card insertion. The second guide element 302 drives the push base 301 to move toward the electromagnetic element 401, and through the pusher 202, drives the ejector pin 201 to push the memory card out of the slot. The card is ejected from the insertion / removal port to automatically eject the memory card. A micro-control switch is also provided in the insertion / removal port. When the card is ejected, the ejector pin 201 touches the micro-control switch to disconnect the power to the electromagnetic component 401. At this time, the electromagnetic component 401 does not engage the second guide component 302. Since the reset elastic component 403 is in a state of compression and deformation under external force during card ejection, when the second guide component 302 is not engaged, the reset elastic component 403 releases its elastic force to drive the push base 301 and the card ejector to reset, so that the ejector pin 201 can contact the memory card when the card is inserted again.

[0040] Working principle and its effects:

[0041] When inserting a memory card, the memory card contacts the ejector pin 201. When the memory card needs to be removed, the touch control switch 402 energizes the electromagnetic component 401, generating a magnetic attraction force. Under the action of the magnetic attraction force, the second guide component 302 is attracted and moves towards the electromagnetic component 401, driving the pusher 301 to move towards the direction of the memory card insertion. In turn, the pusher 202 moves and drives the ejector pin 201 to push out the memory card. When the memory card is pushed out, the ejector pin 201 touches the micro-control switch to de-energize the electromagnetic component 401. Since the reset elastic component 403 is under compression deformation when the card is ejected, when the electromagnetic component 401 no longer attracts the second guide component 302, the reset elastic component 403 releases its elastic force to push the pusher 301 to reset, thereby driving the ejector pin 201 to reset. This realizes automatic card ejection when the memory card needs to be removed, without the need for manual removal.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
