Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic connectors, in particular to an integrated plate-type photovoltaic connector. Background Art

[0002] With the increasing expansion of photovoltaic power generation applications, the applications of inverters and photovoltaic connectors are becoming more and more frequent, and the application environment is becoming more and more complex. The installation party's requirements for the stability and convenience of the connectors are also increasing day by day.

[0003] During use, a photovoltaic generator is generally fixed on the box wall of an inverter. One end extends into the inverter and is connected to the electronic components inside through a cable, and the other end extends outside the inverter and is connected to an electrical device. For the convenience of assembly and fixation, the current photovoltaic connectors are generally tightened on the box wall of the inverter by means of screw and nut cooperation. For example, in the patent documents with patent numbers ZL201720869390.5 and ZL202320736128.5, two currently common male and female photovoltaic connectors are respectively recorded. Threads are provided on the outer walls of their plastic bodies that are connected to electrical devices. During installation and use, only the nuts outside need to be loosened or tightened. However, in actual installation production, due to the different relative placement positions of different electrical devices and the inverter, and the different structural settings of the connectors on different electrical devices, cracks or even fractures may occur in the threaded sections of the photovoltaic connector plastic shells due to excessive radial tension or torsional force during installation or use, and there are safety hazards such as electric leakage during use.

[0026] As Figure 1 shown, an integrated plate-type photovoltaic connector, the photovoltaic connector includes a positioning member 100 and more than one conductive terminal 200 embedded therein, and both ends of each conductive terminal 200 can be electrically connected to a power supply component 300 and an electrical component 400 respectively; wherein:

[0027] The positioning member 100 includes an integrally formed positioning plate 10 and one or more hollow tubes 20. The positioning plate 10 is provided with a first positioning structure 1 for fixing it on the power supply component 300. A plurality of hollow tubes 20 are arranged in parallel and perpendicularly penetrate through the positioning plate 10, and both ends thereof extend to the outside of the positioning plate 10 respectively. A conductive terminal 200 can be fixedly clamped in each hollow tube 20 in a matching manner;

[0028] On the outer wall of each hollow tube 20 facing the electrical component 400 or on its outside, a set of positioning buckles 30 are provided. One end of each set of positioning buckles 30 is connected to and integrally formed with the positioning plate 10, and the other end extends to the outer wall of the end of a hollow tube 20 or its radial outside, so as to cooperate with each hollow tube 20 and the conductive terminal 200 therein to form a female connector end 40 or a male connector end 50.

[0029] The structures of the female connector end 40 and the male connector end 50 are common knowledge to those skilled in the art, and their specific structures will not be elaborated here.

[0030] As Figure 2 shown, it further includes a waterproof component. The waterproof component includes a waterproof pad 60 and a plurality of inner waterproof rings 70. The waterproof pad 60 is embedded on the side wall of the positioning plate 10 facing the power supply component 300 and is sleeved around each hollow tube 20 in a matching manner. The waterproof pad 60 is provided with a second positioning structure 2 on it that is adapted to the first positioning structure 1. Each inner waterproof ring 70 is sleeved on the end of a conductive terminal 200 facing the power supply component 300 and extends to its axial outside; a snap ring 80 is further sleeved on each conductive terminal 200 on the side close to the electrical component 400 of the inner waterproof ring 70. One end of each snap ring 80 is embedded in the inner wall of the hollow tube 20, and the other end is embedded on the conductive terminal 200; an outer waterproof ring 90 is further embedded on the outer wall of each hollow tube 20 separated from one end of the positioning buckle 30.

[0031] In this embodiment, the snap ring 80 is an adjustable ring structure, which is provided with a cut groove 4 extending axially and penetrating through the snap ring 80. One end of the snap ring 80 forms a plurality of elastic arms 5 arranged along its contour and extending obliquely outward. The inner wall of the hollow tube 20 is provided with a card slot that can be engaged with these elastic arms 5. The outer wall of the hollow tube 20 of the male connector end 50 is further provided with a limit groove 6 adapted to the outer waterproof ring 90.

[0032] As Figure 3As shown in the figure, during installation, pass the hollow tube 20 equipped with the conductive terminal 200 through the power supply component 300, make the end of the positioning plate 10 away from the positioning buckle 30 abut against the power supply component 300, and use the locking piece to pass through the first positioning structure 1 to fix the positioning plate 10 thereon. Finally, connect one end of the conductive terminal 200 to the cable or electronic component in the power supply component 300. During use, connect the male connection end on the electrical component 400 to the female connector 40, or connect the female end thereon to the male connector 50. After the photovoltaic connector is installed and fixed to the power supply component 300, the mounting plate 10 tightly presses the waterproof pad 60 against the side wall of the power supply component 300, which can avoid or reduce the entry of water vapor into the photovoltaic connector from the outside of the power supply component 300. The inner waterproof ring 70 can avoid or reduce the entry of water vapor into the photovoltaic connector from the connection end of the power supply component 300, and the outer waterproof ring 90 can avoid or reduce the entry of water vapor into the photovoltaic connector from the connection end of the electrical component 400.

[0033] As Figure 3 shown, in this embodiment, two hollow tubes 20 are provided on the positioning plate 10, and the two hollow tubes 20 and the positioning buckle 30 respectively form the female connector 40 and the male connector 50. In application, as Figures 4 - 6 shown, according to needs, one or more than three hollow tubes 20 can also be provided on the positioning plate 10, and appropriate positioning buckles 30 are selected to form the female connector 40 or the male connector 50; the positioning member 100 and the waterproof component are both insulating members; more than one third positioning structure 3 for fixing the electrical component 400 is formed on each group of positioning buckles 30.

[0034] During the installation and use of the present utility model, only axial pressing force is applied to the integrally formed positioning member 100, and the torsional force and torque are almost zero. Moreover, the plate-shaped positioning plate 10 can significantly increase the contact area between the positioning member 100 and the power supply component 300, improving the stability and multi-directional tensile strength of the positioning member 100, achieving the purpose of avoiding the fracture of the photovoltaic connector and eliminating potential safety hazards.

[0035] The above does not impose any limitation on the technical scope of the present utility model. Any modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
