Description

Technical Field

[0001] The utility model relates to the technical field of weather-resistant photovoltaic connectors, and more particularly to a weather-resistant photovoltaic connector. Background Art

[0002] A weather-resistant photovoltaic connector is a photovoltaic connector designed for outdoor environments and extreme climatic conditions. The existing weather-resistant photovoltaic connector mainly includes a female part and a male part. In the female part, the female terminal is first fixed on the photovoltaic connection line on one side. Then, the female plastic shell is put on the outside of the female terminal and the female terminal is locked on the photovoltaic connection line to protect the female terminal. The installation principle of the male terminal is the same. After the installation is completed, the connection between the female terminal and the male terminal is achieved by plugging the female plastic shell and the male plastic shell, thereby achieving connection between the photovoltaic wires at both ends.

[0003] However, in existing photovoltaic connectors, a gap is likely to exist at the connection point after the female and male plastic shells are plugged in. Although a corresponding sealing structure is provided inside, some moisture will still accumulate in the connection gap between the female and male plastic shells during rainy weather and gradually penetrate inward, affecting the use of the photovoltaic connector.

[0004] In addition, the existing female plastic shell and the male plastic shell are mainly connected and limited by a tongue structure. When disassembling, the female plastic shell and the male plastic shell can be separated by squeezing the tongue structure. However, the plug-in structure of the tongue in the existing technology is in an exposed state, making it easy to disassemble the female plastic shell and the male plastic shell, and the safety protection is poor.

In this way, after the male plastic shell 2 and the female plastic shell 1 are connected together, the protective sleeve 6 can be moved and the threaded locking between the protective sleeve 6 and the locking section 3 can be made, so that the protective sleeve 6 can be stably positioned outside the plug-in connection of the female plastic shell 1 and the male plastic shell 2, thereby preventing the male plastic shell 2 and the female plastic shell 1 from being opened at will, thereby improving the safety and protection of the photovoltaic connector when in use.

[0035] The utility model is provided with a first limiting plate 4 on the outer side of the locking section 3, a first sealing gasket 5 is provided on the inner surface of the first limiting plate 4, and a second limiting plate 7 is provided on the male plastic shell 2, and a second sealing gasket 8 is provided on the outer side of the second limiting plate 7, wherein the second limiting plate 7 is located inside the protective sleeve 6, so that when the protective sleeve 6 is threadedly locked with the locking section 3, its open end will squeeze the first sealing gasket 5 on the first limiting plate 4, and at the same time, the closed end of the protective sleeve 6 will squeeze the second sealing gasket 8 on the second limiting plate 7, so that the second limiting plate 7 and the second limiting plate 7 are connected. The cooperation of the sealing gasket 8 can realize the sealed connection between the protective sleeve 6 and the male plastic shell 2 when the protective sleeve is threadedly locked with the locking section 3. At the same time, the provision of the first limiting plate 4 and the first sealing gasket 5 can realize the sealed connection between the protective sleeve 6 and the female plastic shell 1 when the protective sleeve is threadedly locked with the locking section 3. In this way, the sealing protection of the connection between the male plastic shell 2 and the female plastic shell 1 can be realized, thereby preventing external rainwater, dust, etc. from contacting the connection between the male plastic shell 2 and the female plastic shell 1, thereby improving the protection of the photovoltaic connector during use and improving the use effect.

[0036] The utility model is provided with a latch tongue 9 on the female plastic shell 1, and a socket 10 on the male plastic shell 2. The inner side of the protective sleeve 6 is matched with the latch tongue 9 and is provided with an extrusion portion 11. In this way, when it is necessary to disassemble and separate the male plastic shell 2 and the female plastic shell 1, the protective sleeve 6 is separated from the locking section 3, and the protective sleeve 6 drives the extrusion portion 11 to move during the movement, so that the extrusion portion 11 can squeeze the engaging structure, thereby facilitating the separation between the female plastic shell 1 and the male plastic shell 2.

[0037] See also Figure 1-Figure 7 As an implementation of the latch tongue 9 , the latch tongue 9 includes an elastic connecting strip 12 , a clamping head 13 is provided at the tail end of the elastic connecting strip 12 , and an insertion groove 14 is provided on the clamping base 10 .

[0038] Specifically, the clamping head 13 is passed through the insertion slot 14 to achieve the connection limitation between the clamping head and the clamping seat 10 . The provision of the elastic connecting strip 12 facilitates the deformation adjustment of the clamping head 13 when it moves in and out of the insertion slot 14 .

[0039] See also Figure 1-Figure 7 As an implementation of the clamping head 13: the clamping head 13 includes a limiting section 15 connected to the elastic connecting strip 12, a disassembly extrusion section 16 is provided on the top of the limiting section 15, and an insertion guide section 17 is provided at the front end of the disassembly extrusion section 16.

[0040] Specifically, when the latch tongue 9 is inserted, the guide section 17 is inserted, so that the clamping head 13 can be easily inserted into the insertion groove 14 and moved out from the other side of the base 10. The elastic connecting strip 12 allows the clamping head 13 to move upward after being moved out of the base 10, and the limited insertion between the latch tongue 9 and the base 10 is achieved through the cooperation between the limiting section 15 and the base 10, thereby achieving a stable connection between the female plastic shell 1 and the male plastic shell 2.

[0041] See also Figure 1-Figure 7 As an implementation of the chuck 13 , a first extrusion platform 18 is provided between the top of the disassembly extrusion section 16 and the insertion guide section 17 .

[0042] Specifically, the provision of the first extrusion platform 18 can make the extrusion portion 11 more stable when extruding the chuck 13 .

[0043] See also Figure 1-Figure 7 As an implementation of the extrusion portion 11 , the bottom end of the extrusion portion 11 is provided with a second extrusion platform 19 in cooperation with the first extrusion platform 18 , and extrusion inclined wedge surfaces 20 are provided on both sides of the second extrusion platform 19 .

[0044] Specifically, by setting the extrusion inclined wedge surface 20, the extrusion part 11 can better extrude the clamping head 13 and generate movement, so that when the second extrusion platform 19 is located outside the first extrusion platform 18, the limiting section 15 can be separated from the clamping seat 10 and aligned with the insertion groove 14. At this time, the protective sleeve 6 and the locking section 3 are also in a separated state. Therefore, the male plastic shell 2 can be pulled outward relative to the female plastic shell 1 to achieve the separation of the male plastic shell 2 and the female plastic shell 1, while improving the protection and facilitating the disassembly between the male plastic shell 2 and the female plastic shell 1.

[0045] See also Figure 1-Figure 7 As an implementation of the protective cover 6 , the outer surface of the protective cover 6 is provided with anti-slip grooves 21 .

[0046] Specifically, the anti-slip pattern 21 can improve the anti-slip property of the surface of the protective sleeve 6 when twisting.

[0047] See also Figure 1-Figure 7 As an implementation method of the male plastic shell 2: a placement groove 22 is opened on the male plastic shell 2 and located on one side of the card seat 10, and the placement groove 22 cooperates with the card head 13.

[0048] Specifically, by setting the placement shell, the clamping tongue 9 can be inserted into the clamping seat 10 and the clamping head 13 can be placed to achieve a stable connection between the male plastic shell 2 and the female plastic shell 1.

[0049] See also Figure 1-Figure 7 As an implementation of the female plastic shell 1 and the male plastic shell 2: a third sealing gasket 23 is provided between the contact surfaces of the female plastic shell 1 and the male plastic shell 2.

[0050] Specifically, the provision of the third sealing gasket 23 can improve the sealing performance of the contact surfaces between the female plastic shell 1 and the male plastic shell 2, further improving the sealing and protective effect of the photovoltaic connector during use.

[0051] In summary, when the overall equipment is in use:

[0052] Align the female housing 1 and the male housing 2 so that the clamping head 13 on the clamping tongue 9 is inserted into the insertion groove 14 under the action of the insertion guide section 17 and squeezed out from the other end of the insertion groove 14;

[0053] Under the action of the elastic connecting strip 12, the clamping head 13 can move upward after being moved out of the insertion groove 14, and the limited insertion between the clamping tongue 9 and the clamping seat 10 is achieved through the cooperation between the limiting section 15 and the clamping seat 10, thereby achieving a stable connection between the female plastic shell 1 and the male plastic shell 2;

[0054] Here, the third sealing gasket 23 is located between the contact surfaces of the female plastic shell 1 and the male plastic shell 2, which can improve the sealing between the contact surfaces of the female plastic shell 1 and the male plastic shell 2, and improve the protective effect of the photovoltaic connector when in use;

[0055] Afterwards, the protective sleeve 6 is moved so that the protective sleeve 6 is locked and fixed with the locking section 3, thereby achieving a stable installation of the protective sleeve 6 on the outside of the connection between the female plastic shell 1 and the male plastic shell 2. In this way, the tongue 9 can be prevented from being randomly squeezed, resulting in the separation between the female plastic shell 1 and the male plastic shell 2, thereby improving the safety and protection of the photovoltaic connector during use;

[0056] At the same time, when the protective sleeve 6 is threadedly locked with the locking section 3, its open end will squeeze the first sealing gasket 5 on the first limiting plate 4, and the closed end of the protective sleeve 6 will squeeze the second sealing gasket 8 on the second limiting plate 7. In this way, the cooperation of the second limiting plate 7 and the second sealing gasket 8 can achieve a sealed connection between the protective sleeve 6 and the male plastic shell 2 when the locking section 3 is threadedly locked. At the same time, the provision of the first limiting plate 4 and the first sealing gasket 5 can achieve a sealed connection between the protective sleeve 6 and the locking section 3 when the locking section 3 is threadedly locked. In this way, sealing protection of the connection between the male plastic shell 2 and the female plastic shell 1 can be achieved, thereby preventing external rainwater, dust, etc. from contacting the connection between the male plastic shell 2 and the female plastic shell 1, thereby improving the protection of the photovoltaic connector when in use and improving the use effect;

[0057] When disassembling the utility model, first screw the protective sleeve 6 in the reverse direction to squeeze out the threaded connection between the protective sleeve 6 and the locking section 3;

[0058] At this time, the extrusion portion 11 is located on the side of the clamping head 13 close to the female plastic shell 1. Then, the protective cover 6 is slid outward on the male plastic shell 2. The movement of the protective cover 6 can drive the movement of the extrusion portion 11. The extrusion inclined wedge surface 20 on the extrusion portion 11 can press against the disassembly extrusion section 16 on the clamping head 13, so that the clamping head 13 can move downward.

[0059] When the second extrusion stage 19 on the extrusion portion 11 is located outside the first extrusion stage 18 on the clamping head 13, the limiting section 15 on the clamping head 13 can be separated from the clamping seat 10 and aligned with the insertion groove 14;

[0060] Afterwards, the female plastic shell 1 and the male plastic shell 2 are controlled to be pulled in two directions, so that the female plastic shell 1 and the male plastic shell 2 can be easily separated, thereby improving the overall disassembly convenience.
