[0052] In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of some known functions and known components.

[0053] An embodiment of the present disclosure provides a blind-mating connection structure.

[0054] Figure 1 FIG. 1 is a schematic diagram of a blind plug connection structure according to an embodiment of the present invention. Figure 1 As shown, a blind-mating connection structure of a disclosed embodiment includes:

[0055] The fixing bracket 10 is provided with a first connection structure 100 and a second connection structure 101; wherein the first connection structure 100 is used to fix the bottom of the fixing bracket 10 on the box body 12 of the inverter box;

[0056] The blind-mate connector 11 is provided with a third connection structure 102 , and the third connection structure 102 is used to fix the blind-mate connector 11 on the fixing bracket 10 according to the second connection structure 101 .

[0057] Figure 2 This is a schematic diagram of the installation of the traditional blind plug connection structure. Figure 2 As shown, the traditional blind-plug connection structure is installed from the inside of the inverter box body 12, and the blind-plug connector 11 interferes with the internal structural circuit 13, causing installation difficulties and affecting the internal space layout.

[0058] In the embodiments of the present disclosure, Figure 1As shown, the box body 12 of the inverter box includes an interior and an exterior. The interior of the box body 12 is used to set the circuit and internal structure of the inverter, and the exterior of the box body 12 is the working space of the inverter. Among them, the bottom of the fixed bracket 10 is fixed to the outside of the box body 121 of the inverter, that is, the outside of the shell of the box body 12. The first connecting structure 100 cooperates with the box body 12 to fix the fixed bracket 10. Accordingly, the first connecting structure 100 may include a screw connection structure, a card connection structure or a plug connection structure. The selection of the first connecting structure 100 can be determined according to the shape or material of the box body 12, and is not uniquely limited here.

[0059] The fixing bracket 10 is also provided with a second connection structure 101, and the second connection structure 101 corresponds to the third connection structure 102 and cooperates with each other to fix the blind plug connector 11 to the fixing bracket. As an electrical connection device, the blind plug connector 11 is electrically connected to the internal circuit of the inverter internally, and is electrically connected to external devices through blind plugging externally. After the blind plug connector 11 is fixed to the fixing bracket 10, it is located outside the box body 12 and does not interfere with the internal space of the box body 12. Accordingly, the second connection structure 101 and the third connection structure 102 may include a screw connection structure, a snap connection structure or a plug connection structure. The selection of the second connection structure 101 and the third connection structure 102 can be determined according to the shape or material of the box body 12, and is not uniquely limited here.

[0060] As one of the embodiments, Figure 1 As shown, a blind-mating connection structure of a disclosed embodiment further includes:

[0061] A sealing pad 14 disposed at the bottom of the fixing bracket 10;

[0062] The bottom of the fixing bracket 10 is used to press the sealing gasket 14 onto the box body 12 .

[0063] like Figure 1 As shown, the sealing gasket 14 is arranged between the fixing bracket 10 and the box body 14, and provides a first layer of sealing effect after the fixing bracket 10 is fixed, playing a preliminary protective role.

[0064] As one of the embodiments, Figure 1 As shown, a blind-mating connection structure of a disclosed embodiment further includes:

[0065] The sealing ring 15 is arranged on the top of the fixing bracket.

[0066] like Figure 1 As shown, the sealing ring 15 is arranged on the top of the fixing bracket 10 to provide a second layer of sealing effect for the combination of the blind-plug connector 11 and the fixing bracket 10, thereby playing a further protective role.

[0067] As a preferred implementation, the structural improvement of the fixing bracket 10 has a significant impact on the installation effect of the sealing pad 14 and the sealing ring 15. In particular, the combination of the blind plug connector 11 and the fixing bracket 10 has relatively high requirements for the waterproof effect after installation. In this regard, the embodiment of the present disclosure provides a preferred implementation.

[0068] Figure 3 FIG. 1 is a schematic diagram of a blind plug connection structure of a preferred embodiment. Figure 3 As shown, the fixing bracket includes:

[0069] Sheet-shaped support body 200;

[0070] A connector through hole 201 disposed in the middle of the sheet-shaped bracket body 200;

[0071] Wherein, the first connection structure 100 is arranged at the edge of the sheet-shaped bracket body 200;

[0072] The second connection structure 101 is arranged around the connector through hole 201 .

[0073] The sealing gasket 14 comprises:

[0074] A fourth connection structure 103 is disposed on the edge of the sealing pad 14 ; wherein the fourth connection structure 103 is used to cooperate with the first connection structure 100 to fix the sealing pad 14 on the sheet-like bracket body 200 .

[0075] To simplify the expression and facilitate the understanding of the embodiments of the present disclosure. In the preferred embodiment of the present disclosure, the first connecting structure 100, the second connecting structure 101, the third connecting structure 102 and the fourth connecting structure 103 all adopt a screw connection structure, that is, the screw holes and the screws cooperate to assemble and fix the components. The screw connection structure is also a preferred embodiment, which is convenient for installation and disassembly, and has a better matching effect with the sealing gasket 14 and the sealing ring 15. However, the screw connection structure does not represent the only limitation of the embodiments of the present disclosure. Under the idea of ​​fixed assembly, other connection structures can also be selected, which will not be repeated here.

[0076] The connector through hole 201 is used to accommodate the blind-mate connector 11 , and the blind-mate connector 11 is located in the connector through hole 201 after being fixed.

[0077] As one of the embodiments, Figure 3 As shown, the fixing bracket 10 also includes:

[0078] An annular bracket body 202 disposed around the connector through hole;

[0079] The annular support body 202 is used to surround and fix the sealing ring 15 .

[0080] Figure 4 FIG. 1 is a schematic diagram of a blind plug connection structure assembly according to a preferred embodiment. Figure 4 As shown, the annular support body 202 serves as the surrounding frame of the sealing ring 15, fixes the sealing ring 15 on the top of the sheet support body 200, and surrounds the blind plug connector 11. When the blind plug connector 11 is blind plugged with the outside, the annular support body 202 cooperates with the external structure to compress the sealing ring 15, achieving a good sealing effect during the blind plugging process.

[0081] As another preferred embodiment, Figure 5 Schematic diagram of the improved fixed bracket structure, such as Figure 5 As shown, the sheet-like support body 200 includes:

[0082] A first sheet-shaped body 300 disposed outside the annular bracket body 200;

[0083] A second sheet-shaped body 301 disposed inside the annular bracket body 201;

[0084] The first sheet body 300 and the second sheet body 301 are located in different planes.

[0085] The first sheet 300 and the second sheet 301 are in different planes, that is, when installed on the box body, the first sheet 300 and the second sheet 301 are at different distances from the box body 12, and the pressure on the sealing gasket 14 changes according to the difference in distance. At the junction of the first sheet 300 and the second sheet 301, a greater fixing force is provided to the sealing gasket 14, thereby improving the sealing effect of the sealing gasket 14.

[0086] As a preferred implementation method, Figure 5 As shown, the sheet-like support body 200 includes:

[0087] The distance between the plane where the second sheet 301 is located and the plane where the box body 12 is located is smaller than the distance between the plane where the box body 12 is located and the plane where the first sheet 300 is located.

[0088] like Figure 5 As shown, the closer the second sheet 301 is to the blind-mating connector 11 , the greater the fixing force provided to the sealing gasket 14 , which, in conjunction with the position setting of the screw connection structure, ensures that the sealing gasket 14 has a maximum sealing effect. Figure 6 The schematic diagram of the improved fixed bracket assembly is as follows: Figure 6As shown, the bottom end surface of the second sheet 301 is against the end surface of the box body 12 , and the compression amount of the sealing gasket 14 is controlled by the thickness of the second sheet 301 to ensure the consistency of the installation of the blind-plug connector 11 .

[0089] The blind-plug connection structure of any embodiment of the present disclosure includes a fixing bracket 10 and a blind-plug connector 11. The fixing bracket 10 is provided with a first connection structure 100 and a second connection structure 101, wherein the first connection structure 100 is used to fix the bottom of the fixing bracket 10 on the box body 12 of the inverter box. The blind-plug connector 11 is provided with a third connection structure 102, and the third connection structure 102 is used to fix the blind-plug connector 11 on the fixing bracket 10 according to the second connection structure 101. Through the design of the fixing bracket 10, the blind-plug connector 11 can be installed and fixed outside the inverter box without being affected by the interference of the internal circuit or structure of the inverter box, thereby improving the convenience and stability of installation.

[0090] Based on this, an embodiment of the present disclosure also provides an inverter box.

[0092] Box body;

[0093] A blind-mate connector installation area is provided on the box body; wherein a connector opening is provided in the blind-mate connector installation area;

[0096] As a preferred embodiment, the box body is provided with a concave box groove;

[0097] The box body groove is used to set the blind-mate connector installation area.

[0098] The blind-plug connector installation area is arranged in the groove of the box body, so that the blind-plug connection structure is a hidden design after being installed, which does not destroy the planar visual effect of the box body and protects the blind-plug connection structure.

[0099] The inverter case of the disclosed embodiment includes a case body and a blind-plug connector installation area arranged on the case body, wherein the blind-plug connector installation area is used to install a blind-plug connection structure, and a connector opening is provided in the blind-plug connector installation area to facilitate the electrical connection of the blind-plug connection structure. The blind-plug connection structure includes a fixed bracket and a blind-plug connector.
