Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic connectors, and in particular relates to a protective plug of a photovoltaic connector, a photovoltaic connector component and a photovoltaic connector system. Background Art

[0002] Photovoltaic connectors are an indispensable component in solar photovoltaic power generation systems. They are mainly used to achieve electrical connections between photovoltaic panels, combiner boxes, controllers, inverters and other components. Photovoltaic connectors usually consist of two parts: male connectors and female connectors. They adopt a plug-in design to facilitate quick connection and disconnection during installation and maintenance. In addition to providing electrical connection functions, photovoltaic connectors also have safety features, such as preventing mis-insertion or reverse connection, to ensure the correct operation of the system.

[0003] When designing a photovoltaic connector, it is necessary to consider meeting the long-term use requirements under harsh outdoor environmental conditions, such as waterproof, dustproof, weather resistance and mechanical strength, and ensure stable current and low resistance transmission to reduce power loss. At the same time, due to engineering reasons, the photovoltaic connector may not be used immediately after installation, and it may take several months before it can officially work. During this period, the male and female connectors of the photovoltaic connector are not plugged together, and will be affected by water and dust when exposed to the air. Therefore, the photovoltaic connector needs to be equipped with corresponding protective plugs to prevent performance from being affected.

DETAILED DESCRIPTION

[0053] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0054] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the embodiments of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0055] In the description of the present utility model, Figure 3 and Figure 8 As shown, the left side direction in the figure is "left", the right side direction in the figure is "right", the upper side direction in the figure is "up", and the lower side direction in the figure is "down". The definitions of the above directions are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0056] like Figures 1 to 3 As shown, this embodiment includes a first protective plug 1 of a photovoltaic connector, and the protective plug 1 is configured to be detachably arranged in the receiving end of the female connector 2 of the photovoltaic connector. The first protective plug 1 includes a first body 11, a first protrusion 12 and a first clamping piece 13. Among them, the first protrusion 12 is connected to the first body 11 or is integrally arranged, and the first protrusion 12 is used to be inserted into the receiving end of the female connector 2. The first clamping piece 13 is connected to the first body 11 or is integrally arranged, and the first clamping piece 13 is used to be clamped and matched with the receiving end of the female connector 2. The first protective plug 1 has a use state and a non-use state. When in the use state, the first protrusion 12 and the first clamping piece 13 are located in the female connector 2, and the first clamping piece 13 is in close contact with the surface of the receiving end, so that the groove on the female connector 2 is closed to prevent dust and water from entering from the groove. When in the non-use state, the first protective plug 1 is detached from the female connector 2.

[0057] Specifically, the first clamping member 13 and the first protrusion 12 are located on the same side surface of the first body 11. The line connecting the geometric centers of the first protrusion 12 and the first body 11 is perpendicular to the horizontal plane, that is, the first protrusion 12 is located in the middle of the first body 11. Figures 1 to 3 As shown, the first protrusion 12 is roughly cylindrical. In this embodiment, the number of the first clamping members 13 is preferably two, and the first clamping members 13 are respectively arranged on opposite sides of the first protrusion 12, so that the clamping ground is more firmly and the first protective plug 1 is a symmetrical structure, which is more beautiful.

[0058] The first hook 14 is provided at one end of the first clamping member 13 away from the first body 11, and is used to cooperate with the receiving end of the female connector 2. The first hook 14 is elastic. The first hook 14 is provided with a first surface on the side facing the first body 11. When the first protective plug 1 is in use (i.e., after the first protective plug 1 is set in the receiving end), the first surface is in close contact with the inner surface of the receiving end. Figure 3 It can be seen that the first surface is a first guiding inclined surface 15 that is inclined from the inside to the outside toward the side close to the first body 11 (i.e., inclined downward from the inside to the outside). In this embodiment, taking the central axis passing through the photovoltaic connector as a reference, the side close to the central axis is the inside, and the side away from the central axis is the outside. In some other embodiments, the first surface can also be set as a surface parallel to the horizontal plane, which is not limited here. In this embodiment, setting the first surface as an inclined surface can make the first protective plug 1 and the female connector 2 more firmly connected and less likely to loosen.

[0059] The first hook portion 14 is further provided with a second guiding inclined surface 16. Specifically, Figure 3 As shown, in this embodiment, the second guide slope 16 on the left first clamping member 13 is arranged toward the left side and tilted downward from the inside to the outside, and the second guide slope 16 on the right first clamping member 13 is arranged toward the right side and tilted downward from the inside to the outside. When the first protective plug 1 is switched between the use state and the non-use state, the second guide slope 16 contacts the female connector 2. By providing the second guide slope 16, it is more convenient to insert the first clamping member 13 into the female connector 2.

[0060] like Figure 2 and Figure 3 As shown, the first protective plug 1 also includes a baffle 17, which is connected to or integrally provided with the first body 11. The baffle 17 is located on the outside of the first clip 13. In this embodiment, the number of baffles 17 is also two, that is, a baffle 17 is provided on the outside of each first clip 13. The length of the baffle 17 is greater than or equal to the length of the first clip 13, and it mainly plays the role of protecting the first clip 13 to prevent the first hook 14 of the first protective plug 1 from deformation or breakage during storage or use. A sealing ring 18 is also sleeved on the first protrusion 12, so that the first protective plug 1 can be dustproof and waterproof at the same time.

[0061] like Figures 4 to 6As shown, this embodiment also includes a photovoltaic connector assembly, including a connector and a protective plug. The connector has a receiving end for accommodating another connecting component or a plug-in end for inserting another connecting component. When the photovoltaic connector assembly is in an initial state, the protective plug is detachably arranged in the receiving end or detachably sleeved on the plug-in end. Specifically in this embodiment, the connector is a female connector of a photovoltaic connector, and the female connector has a receiving end for accommodating another connecting component. The photovoltaic connector assembly also includes the above-mentioned first protective plug 1.

[0062] Specifically, the female connector 2 includes a second body 21, one end of which is provided with a first groove 22 and a second groove 23, the first protrusion 12 can be inserted into the first groove 22, and the first clamping member 13 can be inserted into the second groove 23. When the first protective plug 1 is in use, the first protrusion 12 is inserted into the first groove 22, the first clamping member 13 is inserted into the second groove 23, and the first clamping member 13 is in close contact with the inner wall of the receiving end of the female connector 2.

[0063] Specifically, the first groove 22 and the second groove 23 are located on the same side of the second body 21, and the geometric center of the first groove 22 is located on the central axis of the female connector 2 along the length direction. There are two second grooves 23, and the two second grooves 23 are respectively arranged on opposite sides of the first groove 22. When the first protective plug 1 is in use, the two first clamping members 13 are respectively inserted into the second grooves 23. A third guide slope 24 is also provided in the second body 21, and the third guide slope 24 is inclined from the inside to the outside toward the side close to the second groove 23. When the first protective plug 1 is in use, the first guide slope 15 and the third guide slope 24 are in close contact. In this embodiment, preferably, when the first protective plug 1 is in use, the third guide slope 24 and the first guide slope 15 are parallel. There is also a gap between the second groove 23 and the third guide slope 24. When the first protective plug 1 switches from the non-use state to the use state, the first clamping member 13 is inserted into the second groove 23 and passes through the gap and then contacts the third guide slope 24.

[0064] This embodiment also includes a photovoltaic connector system, including a male connector 4, a female connector 2, a first protective plug 1 for cooperating with the female connector 2, and a second protective plug 3 for cooperating with the male connector 4. Among them, the first protective plug 1 and the female connector 2 are as described above, and the details are not repeated here. The photovoltaic connector system has an initial state and a use state. When the photovoltaic connector system is in the initial state, the first protective plug 1 is connected to the female connector 2, the second protective plug 3 is connected to the male connector 4, and the male connector 4 is disconnected from the female connector 2. When the photovoltaic connector system is in use, the first protective plug 1 is disconnected from the female connector 2, the second protective plug 3 is disconnected from the male connector 4, and the male connector 4 is connected to the female connector 2.

[0065] like Figure 7 and Figure 8 As shown, the second protective plug 2 includes a third body 31, a third groove 32 and a fourth groove 33. The third groove 32 is located on the third body 31 to allow the plug-in end of the male connector 4 to be inserted, and the fourth groove 33 is located on the third body 31 to allow the second clamping member 43 on the male connector 4 to be inserted. The second protective plug 3 has a use state and a non-use state. When the second protective plug 3 is in the use state, the plug-in end of the male connector 4 is inserted into the third groove 32, and the second clamping member 43 on the male connector 4 is inserted into the fourth groove 33 and is in close contact with at least a portion of the second protective plug 3, so that the third groove 32 and the fourth groove 33 are closed. When the second protective plug 3 is in the non-use state, the second protective plug 3 is disengaged from the male connector 4.

[0066] like Figure 7 and Figure 8 As shown, the third groove 32 and the fourth groove 33 are located on the same side of the third body 31 , the third groove is opened at the center position of one end of the third body 31 , and there are two fourth grooves 33 , which are respectively arranged on opposite sides of the third groove 32 .

When the second protective plug 3 is in use, the second clamping piece 43 of the male connector 4 is in close contact with the fourth guide slope 34. The fourth guide slope 34 is inclined from the inside to the outside toward the side close to the fourth groove 33 (i.e., the fourth guide slope is inclined downward from the inside to the outside). There is also a gap between the fourth groove 33 and the fourth guide slope 34. When the second protective plug 3 is switched from the non-use state to the use state, the male connector 4 is inserted into the fourth groove 33 and is in close contact with the fourth guide slope 34 after passing through the gap.

[0068] The male connector 4 includes a fourth body 41, a second protrusion 42 and a second clip 43. The second protrusion 42 is connected to or integrally provided with the fourth body 41, and the third groove 32 is used for inserting the second protrusion 42. The second clip 43 is connected to or integrally provided with the fourth body 41, and the fourth groove 33 is used for clipping with the second clip 43. The second clip 43 and the second protrusion 42 are located on the same side surface of the fourth body 41, and the line connecting the geometric centers of the second protrusion 42 and the fourth body 41 is perpendicular to the horizontal plane. In this embodiment, the number of the second clips 43 is preferably two, and the two second clips 43 are respectively arranged on opposite sides of the second protrusion 42.

[0069] The second hook 44 that cooperates with the second protective plug 3 is provided at one end of the second clamping member 43 away from the fourth body 41, and the second hook 44 is elastic. A fifth guide slope 45 is provided on the second hook 44 on the side facing the fourth body 41, and the fifth guide slope 45 is inclined from the inside to the outside toward the side close to the fourth body 41. A sixth guide slope 46 is also provided on the second hook 44, and when the second protective plug 3 switches between the use state and the non-use state, the second protective plug 3 contacts the sixth guide slope 46. Through the sixth guide slope 46, the second clamping member 43 can be more conveniently inserted into the second protective plug 3.
