Description

Technical Field

[0001] This application relates to the field of photovoltaic connectors, and in particular to a dust cover for photovoltaic connectors. Background Technology

[0002] With the widespread application of photovoltaic power generation, photovoltaic modules and module strings are usually connected using photovoltaic connectors.

[0003] Existing photovoltaic connectors, after being installed on modules, will be exposed to the outdoor environment for a period of time. When dust, dirt, or other contaminants come into contact with the conductive components inside the connector, problems can occur. Existing dust covers on the market are prone to being either too loose or too tight when mating with the connector. Utility Model Content

[0004] In order to improve the stability of the connection between the dust cover and the connector, this application provides a dust cover for a photovoltaic connector.

[0005] This application provides a dust cover for a photovoltaic connector, which adopts the following technical solution:

[0006] A dust cover for a photovoltaic connector includes a first cover and a second cover. The first cover is used to insert into a male connector in the connector, and the second cover is used to insert into a female connector in the connector. A positioning mechanism is installed on both the first cover and the second cover. The positioning mechanism includes a first positioning component and a second positioning component. The first positioning component is installed on the first cover and is used to connect to the male connector. The second positioning component is installed on the second cover and includes a limiting rod installed on the second cover, and the limiting rod is used to connect to the female connector.

[0007] By adopting the above technical solution, the first cover is inserted into the male connector, the second cover is inserted into the female connector, and the first positioning component in the positioning mechanism positions the male connector and the first cover, while the limiting rod positions the connection between the second cover and the female connector. This facilitates the improvement of the stability of the connection between the first cover and the male connector, and between the second cover and the female connector, thereby achieving the goal of improving the stability of the connection between the dust cover and the connector.

[0008] In one specific implementation, the first positioning component includes a positioning post, a connecting post, and a positioning element. The positioning post and the connecting post are both disposed on the first cover, and the positioning element is disposed on the side wall of the connecting post. Both the positioning post and the connecting post are used to connect with the male connector.

[0009] By adopting the above technical solution, the positioning post and connecting post on the first cover are respectively inserted into the male connector, and the connection between the positioning post and the male connector is limited by the positioning component, thereby facilitating the maintenance of the stability of the connection between the first cover and the male connector.

[0010] In one specific implementation, the positioning element includes a convex bulge disposed on the side wall of the positioning post, and the convex bulge has at least two layers, and the convex bulge is used to abut against the inner wall of the male connector.

[0011] By adopting the above technical solution and setting a convex male connector, the friction between the positioning post and the male connector is increased, thereby improving the firmness of the connection between the first cover and the male connector.

[0012] In one specific implementation, the second positioning component includes a first insertion port and a second insertion port, both of which are disposed on the second cover, and both the first insertion port and the second insertion port are used to connect with the female connector.

[0013] By adopting the above technical solution, the stability of the second cover being installed on the female connector is improved by using the first insertion port and the second insertion port.

[0014] In one specific implementation, the limiting rod is installed in the second insertion port, and the limiting rod is used to connect with the female connector.

[0015] By adopting the above technical solution, a limiting rod is set in the second insertion port, which is then connected to the female connector, thereby improving the firmness of the connection between the second cover and the female connector.

[0016] In one specific feasible implementation, the first insertion port is further provided with an internal reinforcing rib.

[0017] By adopting the above technical solution and setting reinforcing ribs inside the first insertion port, the strength of the second cover can be improved.

[0018] In one specific implementation, the first cover is provided with a first wire hole, through which the external wire harness is connected to the male connector; the second cover is provided with a second wire hole, through which the external wire harness is connected to the female connector.

[0019] By adopting the above technical solution, the first wiring hole allows the first cover to be connected to the male connector, thus facilitating the reuse of the first cover. Similarly, the second wiring hole facilitates the connection of the second cover to the female connector, also enabling the reuse of the second cover.

[0020] In one specific implementation, the positioning component includes a fastening rod, a fastening ring, a positioning spring, a locking rod, and a locking spring. The fastening rod is disposed in the positioning post along the axial direction of the positioning post, with one end of the fastening rod extending outward from the positioning post. The fastening spring is installed in the positioning post, with one end connected to the fastening rod and the other end connected to the inner wall of the positioning post. The fastening ring is fitted onto the outer wall of the positioning post, and one end of the fastening ring is also connected to the fastening rod via a connecting rod. The side wall of the fastening ring is used to abut against the inner wall of the male connector. The locking rod is installed on the side wall of the fastening rod and is used to abut against the first cover. The locking spring is installed in the fastening rod and is also connected to the locking rod.

[0021] By adopting the above technical solution, when the first cover is engaged with the male connector, pulling the fastening rod causes it to move one end of the fastening ring via the connecting rod. This compresses the positioning spring and shortens the distance between the two ends of the fastening ring, causing the middle part of the fastening ring to bulge away from the positioning post. This bulge abuts against the connection between the male connector and the first cover, thus positioning the first cover on the male connector and maintaining a tight seal between them through the fastening ring. Furthermore, after the fastening rod is in place, the locking rod extends outward under the action of the locking spring and abuts against the top wall of the first cover, thus positioning the fastening rod in its current position and facilitating the stability of the fastening ring seal.

[0022] In one specific implementation, the first cover is further equipped with an unlocking component, which includes an unlocking rod and an unlocking spring. The unlocking rod is mounted on the first cover and is used to abut a locking rod. The unlocking spring is mounted on the unlocking rod and is also connected to the first cover.

[0023] By adopting the above technical solution, when it is necessary to separate the first cover from the male connector, by pushing the unlocking rod, the unlocking rod compresses the unlocking spring and abuts against the locking rod, so that the unlocking rod presses the locking rod into the fastening rod, so that the locking rod releases the positioning of the first cover, so that the fastening rod and the fastening ring can be reset, thereby making it easier to remove the first cover from the male connector.

[0024] In summary, this application includes at least one of the following beneficial effects:

[0025] 1. This application provides a positioning mechanism to facilitate the positioning of the first cover and the second cover on the male connector and the female connector, respectively, thereby improving the stability of the connection between the first cover and the male connector and the stability of the connection between the second cover and the female connector.

[0026] 2. By setting a positioning component, this application positions the connection between the first cover and the male connector when the first cover is engaged with the male connector, thereby facilitating the stability of the first cover installed on the male connector.

[0041] The present application will be further described in detail below with reference to the accompanying drawings.

[0042] Example 1:

[0043] This application discloses a dust cover for a photovoltaic connector, as shown in the embodiments below. Figure 1 and Figure 2 The connector includes a first cover 1 and a second cover 2. The first cover 1 is used to insert into the male connector 4 of the connector, and the second cover 2 is used to insert into the female connector 5 of the connector. The male connector 4 has an insertion interface 41 at the axial position of its end, and connection ports 42 are provided on both sides of the insertion interface 41 at the end of the male connector 4. The female connector 5 has a pin 51 at the axial position of its end, which is inserted into the insertion interface 41. Locking hooks 52 are also provided on both sides of the pin 51 at the end of the female connector 5 for insertion into the connection ports 42. The first cover 1 and the second cover 2 are also equipped with a positioning mechanism 3, which is used to position the first cover 1 installed on the male connector 4 and the second cover 2 installed on the female connector 5.

[0044] Reference Figure 1 and Figure 2 The positioning mechanism 3 includes a first positioning component 31 and a second positioning component 32, as shown in the reference. Figure 1 and Figure 3 The first positioning component 31 includes a positioning post 311, a connecting post 312, and a positioning element. The positioning element includes a protrusion 313. The positioning post 311 is fixedly disposed at the axial position of the first cover 1 and is integrally formed with the first cover 1. There are two connecting posts 312, and the two insertion ports are respectively disposed on both sides of the axis of the positioning post 311. The positioning post 311 is used to be inserted into the insertion interface 41 of the male connector 4, and the connecting post 312 is used to be inserted into the connection port 42 of the male connector 4.

[0045] Reference Figure 3 and Figure 4 The protrusion 313 is fixedly installed on the peripheral side wall of the positioning post 311. The cross-section of the protrusion 313 is circular, and the protrusion 313 is provided in two rings. The two rings of protrusion 313 are arranged on the peripheral side wall of the positioning post 311 along the axial direction of the positioning post 311. The side wall of the protrusion 313 is used to abut against the inner side wall of the insertion interface 41 of the male connector 4.

[0046] Reference Figure 1 The top wall of the first cover 1 is also provided with a first wire hole 11. There are two first wire holes 11, and the two first wire holes 11 are located on both sides of the axis of the first cover 1. The first wire hole 11 is used for the wire harness 6 to pass through, and the first cover 1 is connected to the male connector 4 through the first wire hole 11 via the wire harness 6.

[0047] Reference Figure 2 , Figure 5 and Figure 6 The second positioning component 32 includes a first insertion port 321, a second insertion port 322, and a limiting rod 323. The first insertion port 321 is located at the axial position of the end of the second cover 2 and is used to fit onto the insertion post 51 of the female connector 5. Two second insertion ports 322 are also provided, and both second insertion ports 322 are located at the end of the second cover 2. The two second insertion ports 322 are respectively located on both sides of the axial position of the first insertion port 321, and the second insertion ports 322 are used for the locking hook 52 of the female connector 5 to be inserted.

[0048] Reference Figure 6 and Figure 7 The limiting rod 323 is fixedly installed on the inner side wall of the second insertion port 322, and the limiting rod 323 is used to engage with the locking hook 52.

[0049] Reference Figure 6 and Figure 7 The first insertion port 321 of the second cover 2 is also fixedly installed with an internal reinforcing rib 324. There are four internal reinforcing ribs 324, and all four internal reinforcing ribs 324 are fixedly installed on the inner wall of the first insertion port 321. The four internal reinforcing ribs 324 are evenly distributed on the inner wall of the first insertion port 321 along the circumferential direction.

[0050] Reference Figure 2 and Figure 6 A connecting plate is also fixedly installed on the side wall of the second cover 2. A second wire hole 21 is provided on the connecting plate. The second wire hole 21 is used for the wire harness 6 to pass through. The second cover 2 is also connected to the female connector 5 through the second wire hole 21 via the wire harness 6.

[0051] The working principle of this embodiment is as follows: by inserting the first cover 1 into the male connector 4, the positioning post 311 on the first cover 1 is inserted into the insertion interface 41 of the male connector 4, and the protrusion 313 on the positioning post 311 abuts against the inner wall of the insertion interface 41, thereby limiting the positioning post 311, and allowing the connecting post 312 to be inserted into the connecting port 42 of the male connector 4, thereby completing the installation of the first cover 1 on the male connector 4, thereby preventing dust from entering the male connector 4.

[0052] When the male connector 4 is needed, the first cover 1 is removed from the male connector 4 to facilitate its use. The removed first cover 1 is also connected to the male connector 4 by a wire harness 6, which prevents the first cover 1 from being lost and facilitates its reuse.

[0053] By placing the second cover 2 onto the female connector 5, the first insertion port 321 on the second cover 2 is fitted onto the insertion post 51 of the female connector 5, and the locking hook 52 on the female connector 5 is inserted into the second insertion port 322, so that the limiting rod 323 is engaged with the locking hook 52, thereby achieving the action of positioning the second cover 2 on the female connector 5, thereby preventing dust from entering the female connector 5.

[0054] When the female connector 5 is needed, the second cover 2 is removed from the female connector 5 to facilitate its use. The removed second cover 2 is also connected to the female connector 5 via a wire harness 6, thereby preventing the second cover 2 from being lost and facilitating its subsequent reuse.

[0055] Example 2:

[0056] Reference Figure 8 and Figure 9 The difference between Embodiment 2 and Embodiment 1 is that the positioning component includes a fastening rod 314, a fastening ring 315, a positioning spring 316, a locking rod 317, and a locking spring 318. The fastening rod 314 is slidably installed in the positioning post 311 along the axial direction of the positioning post 311. (Refer to...) Figure 9 and Figure 10The positioning post 311 on the first cover 1 is hollow inside, and one end of the fastening rod 314 passes through the top wall of the first cover 1 in a direction away from the positioning post 311. A limiting groove 12 for sliding the fastening rod 314 is provided on the top wall of the first cover 1. The limiting groove 12 communicates with the internal space of the positioning post 311. A guide plate 319 is fixedly installed on the side wall of the end of the fastening rod 314 located inside the positioning post 311. The guide plate 319 has a circular cross-section, and the outer diameter of the guide plate 319 is larger than the diameter of the fastening rod 314. A positioning spring 316 is sleeved on the fastening rod 314, and the positioning spring 316 is located inside the positioning post 311. One end of the positioning spring 316 abuts against the top wall of the guide plate 319, and the other end abuts against the inner top wall of the internal space of the positioning post 311.

[0057] Reference Figure 9 and Figure 10 The fastening ring 315 is made of rubber and can undergo elastic deformation. The fastening ring 315 is fitted on the outer wall of the positioning post 311, and the outer diameter of the fastening ring 315 is smaller than the inner diameter of the insertion interface 41 of the male connector 4. The upper end of the fastening ring 315 is fixedly connected to the side wall of the positioning post 311, and the lower end of the fastening ring 315 is fixedly installed with a connecting rod 3110. The side wall of the fastening ring 315 is used to abut against the inner wall of the insertion interface 41 of the male connector 4. One end of the connecting rod 3110 passes through the side wall of the positioning post 311 and is fixedly connected to the side wall of the guide plate 319. The axis of the connecting rod 3110 is perpendicular to the axis of the positioning post 311, and a guide groove for the sliding of the connecting rod 3110 is provided on the side wall of the positioning post 311.

[0058] Reference Figure 10 and Figure 11 When the first cover 1 is engaged with the male connector 4, the fastening rod 314 is pulled upward, causing the guide plate 319 to move upward and compress the positioning spring 316. This causes the guide plate 319 to push the lower end of the fastening ring 315 upward through the connecting rod 3110. Since the upper end of the fastening ring 315 is fixed, the middle plate portion of the fastening ring 315 protrudes away from the positioning post 311, and the protruding portion of the fastening ring 315 abuts against the inner wall of the insertion interface 41 of the male connector 4, thereby limiting the positioning post 311 on the male connector 4. The fastening ring 315 also improves the sealing between the positioning post 311 and the insertion interface 41 of the male connector 4.

[0059] Reference Figure 10 and Figure 11The locking rod 317 is slidably mounted on the side wall of the fastening rod 314 in a direction perpendicular to the axis of the fastening rod 314, and a groove for sliding the locking rod 317 is provided on the side wall of the fastening rod 314. One end of the locking rod 317 extends outward from the groove and abuts against the top wall of the first cover 1. The locking spring 318 is installed in the groove, and one end of the locking spring 318 abuts against the inner wall of the groove, and the other end abuts against the end of the locking rod 317 located in the groove.

[0060] Reference Figure 9 and Figure 12 The first cover 1 is also equipped with an unlocking component 7, which includes an unlocking rod 71 and an unlocking spring 72. A sliding sleeve 73 is fixedly installed on the top wall of the first cover 1. The unlocking rod 71 is slidably installed in the sliding sleeve 73 on the top wall of the first cover 1 along the axial direction of the locking rod 317, and one end of the unlocking rod 71 extends toward the locking rod 317. An unlocking arc plate 74 is fixedly installed on the end of the unlocking rod 71 near the locking rod 317. The unlocking arc plate 74 is used to abut the end of the locking rod 317. A baffle 75 is fixedly installed on the end of the unlocking rod 71 away from the unlocking arc plate 74. The unlocking spring 72 is installed on the unlocking rod 71 and is located between the baffle 75 and the sliding sleeve 73. One end of the unlocking spring 72 abuts the side wall of the baffle 75, and the other end abuts the side wall of the sliding sleeve 73.

[0061] The working principle of this embodiment is as follows: When the first cover 1 is engaged with the male connector 4, the positioning pin 311 on the first cover 1 is inserted into the insertion interface 41 of the male connector 4. Then, the fastening rod 314 is pulled, causing the fastening rod 314 to drive the connecting rod 3110 to move towards the positioning spring 316 through the guide plate 319. This causes the guide plate 319 to compress the positioning spring 316. At the same time, the connecting rod 3110 drives one end of the fastening ring 315 to move towards the top wall of the first cover 1, thereby... The distance between the lower and upper ends of the fastening ring 315 is shortened, causing the middle part of the fastening ring 315 to bulge away from the positioning post 311 and abut against the inner wall of the insertion interface 41. At the same time, the locking rod 317 moves past the top wall of the first cover 1 as the fastening rod 314 moves, causing the locking rod 317 to move out of the slide groove under the action of the locking spring 318, so that one end of the locking rod 317 extends out of the slide groove and abuts against the top wall of the first cover 1, thereby positioning the fastening rod 314 in the current position.

[0062] When the first cover 1 needs to be removed from the male connector 4, by pressing the baffle 75, the unlocking rod 71 is pushed towards the fastening rod 314 and the unlocking spring 72 is compressed. This causes the unlocking rod 71 to move the unlocking arc plate 74 to the end that abuts the locking rod 317, and pushes the locking rod 317 into the fastening post, so that the locking rod 317 retracts into the slide groove and compresses the locking spring 318. When the locking rod 317 retracts into the groove, it separates from the first cover 1, causing the guide plate 319 on the fastening rod 314 to move downward under the action of the positioning spring 316. This causes the guide plate 319 to move the fastening rod 314 and the connecting rod 3110 away from the top wall of the first cover 1. This causes the fastening rod 314 to move the locking rod 317 downward until it abuts against the inner wall of the limiting groove 12. At the same time, the connecting rod 3110 causes the lower end of the fastening ring 315 to move downward, making the originally protruding fastening ring 315 gradually flatten. This makes the side wall of the fastening ring 315 no longer abut against the inner wall of the insertion interface 41, thus facilitating the removal of the first cover 1 from the male connector 4.

[0063] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be included within the scope of protection of this application.
