[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0031] As described in the background technology, the existing waterproof connectors are prone to the problem that the wire harness is not convenient to thread or the wire harness end cannot pass through the through hole of the wire sealing body. To this end, the utility model provides a new wiring structure, which has a simple structure and can solve the problem that the wire harness is not convenient to thread or the wire harness end cannot pass through the through hole of the wire sealing body in the prior art.

[0032] The wiring structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0033] See also Figures 1 to 3 As shown, according to an embodiment of the present invention, a wiring structure is provided. Specifically, the wiring structure in this embodiment includes a housing component 10 , a wire end component 20 and a wire sealing body 30 .

[0034] Among them, a cavity 111 is provided on the shell component 10; the wire end component 20 is provided in the cavity 111, and a wiring portion 21 is provided on the wire end component 20, and the wiring portion 21 is used to connect a wiring harness (not shown in the figure); a wire sealing body 30 is provided in the cavity 111, and a wire passing hole 31 for the wire harness to pass through is provided on the wire sealing body 30, and a gap 32 is also provided on the wire sealing body 30, and the gap 32 is located on the side wall of the wire passing hole 31 and extends from the wire passing hole 31 to the outer edge of the wire sealing body 30.

[0035] When the wiring structure in this embodiment is used for wiring, first connect one end of the wire harness to the wiring portion 21, then pass the other end of the wire harness through the wire hole 31 on the wire sealing body 30 from the cavity 111, and then fix the wire sealing body 30 in the cavity 111. When the end of the wire harness is provided with a structure with a diameter larger than the wire hole 31, an external force can be applied to the gap 32 to break the gap 32 open. At this time, the main body of the wire harness can enter the wire hole 31 from the gap 32 without passing the wire harness end with a relatively large diameter through the wire hole 31. That is to say, the utility model provides a slit 32 on the side wall of the wire passing hole 31 extending from the wire passing hole 31 to the outer edge of the wire sealing body 30. When the diameter of the end of the wire harness is relatively large, the wire harness body can be passed through the slit 32 into the wire passing hole 31 without passing the wire harness end with a relatively large diameter through the wire passing hole 31. The situation where the wire harness cannot pass through the wire passing hole 31 will not occur. The structure is simple and it is convenient to connect the wire harness.

[0036] Specifically, the housing component 10 in this embodiment includes a first shell 11 and a second shell 12, wherein a cavity 111 is provided on the first shell 11, and the wire end component 20 is provided at the bottom of the cavity 111; the second shell 12 is detachably connected to the first shell 11, so as to lock the sealing body 30 in the cavity 111. Optionally, the first shell 11 and the second shell 12 in this embodiment can both be provided in a cylindrical structure, and the cylindrical structure can be, for example, a cylinder, or a prism, an elliptical column or other special-shaped cylindrical structures. The first shell 11 and the second shell 12 are enclosed inside to form the aforementioned cavity 111, and the wire end component 20 is fixedly provided at the bottom of the cavity 111, and the wire end component 20 can be fixed at the bottom of the cavity 111 by bonding, clamping, screwing or welding. The wiring part 21 on the wire end component 20 can be a pin wiring part, or a wiring part in other forms, which can be designed and selected according to actual use requirements, and is not specifically limited in the utility model.

[0037] Furthermore, in this embodiment, the first housing 11 and the second housing 12 are connected by threads or buckles, which has a simple structure and is easy to disassemble and assemble. Figure 2 As shown, the first shell 11 is provided with a threaded section, and the second shell 12 is a nut structure. The second shell 12 is provided with an internal thread. The sealing body 30 can be locked in the cavity 111 through the connection of the internal and external threads, and the threaded connection method has a certain waterproof effect, which can improve the waterproof performance of the connection structure in this embodiment and prevent external water from entering the wiring part 21 of the wire end component 20.

[0038] See also Figure 2 As shown, an annular enclosure 112 is provided on the first shell 11 in this embodiment, and the annular enclosure 112 is arranged around the outer periphery of the cavity 111. The outer periphery of the annular enclosure 112 is provided with the aforementioned threaded section, which is convenient for threading with the internal thread on the second shell 12. In addition, a plurality of openings 113 are provided on the circumference of the annular enclosure 112 in this embodiment. Through the function of the openings 113, a certain escape space can be provided for the deformation of the annular enclosure 112, which is more suitable for sleeve the second shell 12 on the annular enclosure 112. In addition, by providing the openings 113 on the circumference of the annular enclosure 112, it is more suitable for receiving the sealing body 30 in the cavity 111.

[0039] In order to facilitate the wire harness to pass through the wiring structure in this embodiment, an avoidance through hole 122 is provided on the second shell 12 of the utility model. The axis of the avoidance through hole 122 is parallel to the axis of the wire hole 31. That is to say, the extension direction of the avoidance through hole 122 and the wire hole 31 in this embodiment is consistent, and the avoidance through hole 122 is arranged opposite to the wire hole 31. When the wire harness is actually connected, the second shell 12 is removed, and one end of the wire harness is connected to the wiring part 21 on the wire end component 20, and then the other end of the wire harness is passed through the wire hole 31 on the sealing body 30. When the outer diameter of the end of the wire harness is larger than the inner diameter of the wire hole 31, the main body of the wire harness enters the wire hole 31 from the side of the gap 32, and the end of the wire harness does not need to pass through the wire hole 31. Finally, the wire harness passes through the wiring structure from the avoidance through hole 122, and then the second shell 12 is screwed on the first shell 11. The structure is simple and easy to operate.

[0040] Further, the cross-sectional area of ​​the avoidance through hole 122 in this embodiment is smaller than the cross-sectional area of ​​the sealing body 30. It can be understood that the cross-sectional area of ​​the avoidance through hole 122 mentioned here refers to the area obtained by cutting the avoidance through hole 122 along the axial direction perpendicular to the avoidance through hole 122, and the cross-sectional area of ​​the sealing body 30 refers to the area obtained by cutting the sealing body 30 along the axial direction perpendicular to the wire hole 31 on the sealing body 30. In this embodiment, by making the cross-sectional area of ​​the avoidance through hole 122 smaller than the cross-sectional area of ​​the sealing body 30, after the second shell 12 is screwed and fixed on the first shell 11, the sealing body 30 can be locked in the cavity 111 by the second shell 12 stopper, which can prevent the sealing body 30 from falling out of the avoidance through hole 122, and the structure is stable and reliable.

[0041] Combination Figures 1 to 3 As shown, the wire sealing body 30 in this embodiment is a columnar structure, the wire passing hole 31 is set through along the length direction of the columnar structure, and the gap 32 extends along the radial direction of the columnar structure. Of course, in other embodiments of the utility model, the wire sealing body 30 can also be a structure of other shapes, as long as the wire passing hole 31 can be set and the wire harness can be sealed.

[0042] Optionally, the wire-passing hole 31 and the slit 32 in this embodiment can be one, two or more. In a preferred embodiment of the present invention, the wire-passing hole 31 and the slit 32 are both provided in plurality, and the plurality of wire-passing holes 31 and the plurality of slits 32 are provided in one-to-one correspondence, so as to facilitate the connection of multiple wire harnesses. Exemplarily, the wire-passing hole 31 and the slit 32 in this embodiment can be two, three or more. Figures 1 to 3 FIG. 3 shows a situation where there are four wire holes 31 and four slits 32 .

[0043] Furthermore, the wire sealing body 30 in the present embodiment is an elastic body, and the elastic body is interference-fitted with the housing component 10, that is, the elastic body in the present embodiment is connected with the cavity 111 by interference fit, and such a configuration can avoid the existence of a gap between the elastic body and the cavity 111, thereby preventing water and the like from entering the wiring portion 21. Exemplarily, the elastic body in the present embodiment can be a rubber body, or a silicone body, or a plastic body, etc., as long as it has a certain elasticity and can have a sealing effect on the wiring harness, other deformation modes are within the protection scope of the present utility model.

[0044] It should be noted that in this embodiment, the size of the gap 32 is relatively small. When the elastomer is in a natural state (not squeezed), the width of the gap 32 is almost 0. This setting can prevent water and the like from entering the cavity 111 through the gap 32.

[0045] Furthermore, the wiring structure further includes a sealing ring (not shown in the figure), which is detachably sleeved on the outer periphery of the wire sealing body 30. It can be understood that the sealing ring in this embodiment is a deformable rubber ring. After the wire harness passes through the wire sealing body 30, the sealing ring is sleeved on the outer periphery of the wire sealing body 30, which can compact the gap 32 on the wire sealing body 30, and then the wire harness can be well sealed on the wire sealing body 30. In addition, in this embodiment, by detachably sleeved on the wire sealing body 30, it is convenient to remove it for installation of the wire harness.

[0046] Of course, in other embodiments of the present application, the wiring structure may not be provided with a sealing ring, as long as the sealing body 30 has sufficient elasticity, when the sealing body 30 is in a natural state, the width of the gap 32 is zero, and water or dust will not enter the cavity 111 through the gap.

[0047] Furthermore, the wiring structure in the present embodiment also includes a plugging head 40, which is detachably inserted into the wire hole 31. When it is not necessary to connect the wiring harness, the plugging head 40 is inserted into the wire hole 31 to prevent water, dust, etc. from entering the cavity 111 of the wiring structure from the wire hole 31. When it is necessary to connect the wiring harness, the plugging head 40 can be removed from the wire hole 31. Optionally, the plugging head 40 in the present embodiment is an elastic columnar structure, which can be, for example, a rubber column, a plastic column, or a silicone column, etc., with a simple structure and easy implementation.

[0048] In combination with the above description, it can be known that the present application opens a slit 32 on the side wall of the wire sealing body 30, and makes the slit 32 connected with the wire passing hole 31, so that the finished wire harness can be conveniently passed from the slit 32 to the wire passing hole 31, and a sealing ring (not shown in the figure) is sleeved on the wire sealing body 32, which can have a good sealing effect on the wire harness passed through the wire passing hole 32, and the threading is simple and quick.

[0049] On the other hand, the utility model also provides a device, which may be, for example, a photovoltaic inverter, etc. The device includes the wiring structure in the above embodiment, and therefore, the device includes all technical effects of the wiring structure in the above embodiment.

[0050] Specifically, when the wiring structure is used in a photovoltaic inverter or other device for wiring, one end of the wire harness is first connected to the wiring portion 21, and then the other end of the wire harness is passed through the wire hole 31 on the wire sealing body 30 from the cavity 111, and then the wire sealing body 30 is fixedly installed in the cavity 111. When the end of the wire harness is provided with a structure with a diameter larger than the wire hole 31, an external force can be applied to the gap 32 to break the gap 32 open. At this time, the main body of the wire harness can enter the wire hole 31 from the gap 32 without passing the wire harness end with a relatively large diameter through the wire hole 31. That is to say, the utility model provides a slit 32 on the side wall of the wire passing hole 31 extending from the wire passing hole 31 to the outer edge of the wire sealing body 30. When the diameter of the end of the wire harness is relatively large, the wire harness body can be passed through the slit 32 into the wire passing hole 31 without passing the wire harness end with a relatively large diameter through the wire passing hole 31. The situation where the wire harness cannot pass through the wire passing hole 31 will not occur. The structure is simple and it is convenient to connect the wire harness.

[0051] Furthermore, in order to install the wiring structure in this embodiment on a photovoltaic inverter and other devices, a wiring portion may also be provided on the shell component 10 in this embodiment, such as a connecting clip, a connecting stud and other structures. As long as other deformation methods are based on the conception of the present invention, they are within the protection scope of the present invention.

[0052] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0053] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
