DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0035] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0036] This embodiment provides an adapter that can realize the conversion between a straight head and an elbow. Figure 1 The adapter is used to connect the photovoltaic connector to the board-end socket 7 on the communication equipment installation panel 6, and the adapter can realize the communication connection between the photovoltaic connector and the communication equipment.

[0037] Reference Figure 1 and Figure 2Specifically, the adapter includes a first adapter portion 101 and a second adapter portion 102 connected to each other, the first adapter portion 101 and the second adapter portion 102 constitute an L-shaped adapter body 1, and the two free ends of the adapter body 1 are respectively provided with a male plug 3 and a female plug 2 that match each other. When the female plug 2 is arranged at the free end of the first adapter portion 101, the male plug 3 is arranged at the free end of the second adapter portion 102; conversely, when the male plug 3 is arranged at the free end of the first adapter portion 101, the female plug 2 is arranged at the free end of the second adapter portion 102.

[0038] In this embodiment, the female plug 2 can be plugged with the board-end socket 7 of the communication device or the communication plug of the photovoltaic connector, and the male plug 3 can be used to be plugged with the communication plug of the photovoltaic connector body 5 or the board-end socket 7 of the communication device. When the female plug 2 is plugged with the board-end socket 7 of the communication device, the male plug 3 is plugged with the communication plug of the photovoltaic connector body 5; vice versa, the same applies.

[0039] A metal conductive part is provided inside the L-shaped adapter body 1, wherein one end of the metal conductive part is connected to the female plug 2, and the other end of the metal conductive part is connected to the male plug 3. When the photovoltaic connector body 5 is connected to the board-end socket 7 of the photovoltaic device through the adapter body 1, the communication connection between the photovoltaic connector body 1 and the photovoltaic device can be achieved through the metal conductive part.

[0040] The L-shaped adapter with the above structure can transform a 180° photovoltaic connector into a 90° photovoltaic connector, which helps to avoid using a 180° photovoltaic connector to directly connect to communication equipment, causing the cable at the tail of the photovoltaic connector to be at a large angle, which in turn causes the plug of the photovoltaic connector to be continuously stressed. The use of adapters helps to improve the reliability of the photovoltaic connector communication connection process, and there is no need to redevelop a 90° photovoltaic connector mold, thereby reducing development costs and cycles.

[0041] In addition, the female plug 2 and the male plug 3 are arranged at the head and tail ends of the L-shaped adapter, and the adapter body 1 can be adapted to two different types of photovoltaic connectors or two different board-end sockets 7 by reversing the direction, which has a wide range of uses.

[0042] Reference Figure 1-Figure 3 In order to further improve the reliability of the communication connection of the photovoltaic connector, in this embodiment, a card connector 4 is provided on the adapter body 1, and the card connector 4 includes two card blocks 41. The two card blocks 41 are relatively arranged on one of the free end side walls of the adapter body 1, and the other free end side wall of the adapter body 1 is provided with two opposite card slots 43. The communication device and the photovoltaic connector body 5 are both provided with a card slot 4 corresponding to the card block 41 or a card block 41 corresponding to the card slot 43.

[0043] The clamping block 41 includes a first clamping portion 411 and a second clamping portion 412. The first clamping portion 411 is arranged on the free end side wall of the first adapter portion 101 or the second adapter portion 102, and the second clamping portion 412 is arranged on the free end side wall of the first clamping portion 411. The longitudinal cross-sectional area of ​​the second clamping portion 412 decreases from the side close to the adapter body 1 to the side away from the adapter body 1, so that the side wall of the second clamping portion 412 is formed with a guide slope 413, and then through the guide slope 413, it is convenient for the clamping block 41 to be inserted into the clamping groove 43.

[0044] It should be noted that in order to achieve the stability of the snap-in connection between the card block 41 and the snap-in groove 43, the first snap-in portion 411 and the second snap-in portion 412 in this embodiment are both integrally formed of a plastic material, and the plastic material has good elasticity, so that the first snap-in portion 411 and the second snap-in portion 412 constitute an elastic structural member. By utilizing the elasticity of the first snap-in portion 411 and the second snap-in portion 412 themselves, they can be stably pressed against the groove wall of the snap-in groove 43, so that the card block 41 is tightly inserted into the card seat 42, which helps to improve the stability of the photovoltaic connector connected to the communication equipment.

[0045] Reference Figure 3 In order to facilitate the removal of the card block 41 from the card slot 43, the side wall of the adapter body 1 located at the card slot 43, the side wall of the communication device located at the card slot 43, and the side wall of the photovoltaic connector body 5 located at the card slot 43 are all sleeved with an unlocking sleeve 42, and the unlocking sleeve 42 is provided with an unlocking groove 421, and the unlocking groove 421 is connected with the card slot 43. When the card block 41 is inserted into the card slot 43, part of the side wall of the card block 41 extends into the unlocking groove 421. The setting of the unlocking groove 421 on the unlocking sleeve 42 makes it easy for personnel to insert the unlocking groove 421 with the help of a screwdriver or other auxiliary equipment, and push the part of the side wall of the card block located in the unlocking groove 421 into the card slot 43 by means of a screwdriver or other auxiliary equipment. At this time, the card block 41 can be removed from the card slot 43, thereby realizing a detachable connection between the adapter body 1 and the photovoltaic device.

[0046] This embodiment also provides a photovoltaic connector. Figure 1 The photovoltaic connector includes a photovoltaic connector body 5 and an adapter, and the adapter is used to connect between the communication plug of the photovoltaic connector body 5 and the board-end socket 7 on the communication equipment installation panel 6. The adapter is as described above.

[0047] Converting a 180° photovoltaic connector into a 90° photovoltaic connector through an adapter can help avoid the situation where the 180° photovoltaic connector is directly connected to communication equipment, causing the cable at the rear of the photovoltaic connector to be at a large angle, thereby causing continuous stress on the plug part of the photovoltaic connector. This helps to improve the reliability of the photovoltaic connector communication connection process, and there is no need to redevelop the 90° photovoltaic connector mold, thereby reducing development costs and cycles.

[0048] Reference Figure 1 and Figure 3 It should be noted that, in this embodiment, there are at least two photovoltaic connector bodies 5, the communication plugs of the two photovoltaic connector bodies 5 are of different models, and at least two board-end sockets 7 are provided on the installation panel 6 of the communication equipment, and the models of the two board-end sockets 7 are different.

[0049] Among them, refer to Figure 1 and Figure 4 The female end plug 2 of the adapter is used to be plugged with one of the board-end sockets 7 or the communication plug of one of the photovoltaic connector bodies, and the male end plug 3 of the adapter is used to be plugged with another board-end socket 7 or the communication plug of another photovoltaic connector body 5. By setting the male end plug 3 and the female end plug 2 of the adapter to have different structures, one adapter can be adapted to two different types of board-end sockets 7 and two different 180° photovoltaic connectors by turning the direction of the adapter, so as to provide customers with application options in different scenarios, with a wide range of applications.
