Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic connectors, in particular to a dual-core photovoltaic connector. Background Art

[0002] With the widespread application of photovoltaic power generation, connectors are widely used in the connection between photovoltaic modules and module strings, and the DC end connection of equipment such as combiner boxes and inverters.

[0003] Most existing photovoltaic connectors are male-female plug-in structures. After the male and female connectors are plugged in, the male buckle and the female buckle are used to assemble and connect. In this plug-in method, the buckle on the male end is exposed to the outside, which is easy to break during transportation and installation, and lacks protection.

[0004] At the same time, when shaking occurs during operation, the connector after plugging is easy to loosen, and the electrical performance cannot be guaranteed to be stable. Therefore, there is an urgent need for a connector that effectively protects the buckle and is firm and stable after plugging. Utility Model Content

[0005] The utility model aims to provide a dual-core photovoltaic connector to solve the problems existing in the background technology.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] A dual-core photovoltaic connector comprises a male connector and a female connector, wherein the male connector is provided with two groups of sockets, buckles are provided on both sides of the sockets, the female connector is provided with a clamping head clamped with the buckles, the length of the buckles is less than the length of the sockets, the two buckles are arranged in an inverted V shape, the male connector is provided with a shell, the shell is provided with a guard plate at a position corresponding to the socket, the two guard plates are arranged in a V shape, a limiting ring is provided outside the shell, the limiting ring is elastically connected to the shell, and the guard plate abuts against the buckle through the limiting ring.

[0008] Through the above technical solution, after the male and female heads are connected by means of the buckle and the clamping head, the protective plate is squeezed by the limiting ring so that the protective plate is pressed against the outside of the buckle, thereby protecting the connection between the buckle and the clamping head on the female head. At the same time, the protective plate is pressed against the buckle, making it difficult for the buckle to fall out of the clamping port on the female head, thereby enhancing the connection strength.

[0009] Furthermore, a connecting plate is provided on the shell, and two connecting plates are symmetrically arranged on both sides of the shell, and the connecting plates are located below the limiting ring.

[0010] Furthermore, a spring is provided between the connecting plate and the limiting ring, one end of the spring is fixedly connected to the connecting plate, and the other end of the spring is fixedly connected to the limiting ring.

[0011] Furthermore, when the spring is in compression, the limiting ring is located below the guard plate; when the spring is in static state, the limiting ring is located in the middle of the guard plate.

[0012] Furthermore, the outer dimension of the outer shell is the same as the inner dimension of the limiting ring, and the limiting ring is slidably connected to the outer shell.

[0013] Furthermore, the size of the guard plate is larger than the size of the buckle, and a pressure column is provided on one side of the guard plate close to the buckle, and one end of the pressure column close to the buckle is spherical.

[0014] Furthermore, the housing comprises a mounting portion, the inner dimension of the mounting portion is matched with the outer dimension of the male plug, and the socket extends out of the housing.

[0015] Furthermore, the buckle and the guard plate are made of flexible plastic material.

[0016] The beneficial effects of the utility model are:

[0017] 1) Protect the buckle to prevent it from collision and damage. Put the outer shell on the outside of the male head to connect them into a whole. At this time, the buckle is in the guard plate, and the guard plate protects the buckle.

[0018] 2) Improve the connection strength and prevent the male and female connectors from loosening. The limit ring moves upward under the action of the spring, and the limit ring closes the guard plate that is open to both sides, and the guard plate moves closer to the buckle. At the same time, the pressure column presses the buckle tightly. At this time, the guard plate presses against the buckle under the action of the limit ring to complete the locking of the buckle.

[0026] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0028] like Figure 1-Figure 6 As shown, a dual-core photovoltaic connector includes a male connector 1 and a female connector 2, wherein the male connector 1 is provided with two groups of sockets 101, buckles 102 are provided on both sides of the sockets 101, the female connector 2 is provided with a clamping head clamped with the buckle 102, the length of the buckle 102 is smaller than the length of the socket 101, and the two buckles 102 are arranged in an inverted V shape, the male connector 1 is provided with a shell 3 outside, and the position of the shell 3 corresponding to the socket 101 is provided with a guard plate 304, and the two guard plates 304 are arranged in a V shape, and a limiting ring 301 is provided outside the shell 3, and the limiting ring 301 is elastically connected to the shell 3, and the guard plate 304 abuts against the buckle 102 through the limiting ring 301.

[0029] Through the above technical solution, the male connector 1 is protected by providing a shell 3 outside the male connector 1, and the guard plate 304 on the shell 3 covers the buckle 102, thereby protecting the buckle 102 and preventing the buckle 102 from collision and breakage.

[0030] When the male connector 1 and the female connector 2 are connected by the buckle 102 and the clamping head, the protective plate 304 is squeezed by the limiting ring 301 so that the protective plate 304 is pressed against the outside of the buckle 102, thereby protecting the connection between the buckle 102 and the clamping head on the female connector 2. At the same time, the protective plate 304 is pressed against the buckle 102, making it difficult for the buckle 102 to fall out of the clamping port on the female connector 2, thereby enhancing the connection strength.

[0031] The specific implementation is as follows:

[0032] See also Figure 5 and Figure 6 , Figure 5 This is the schematic diagram of male connector 1. Figure 6It is a schematic diagram of the shell 3. The size of the mounting portion of the shell 3 is compatible with the outer size of the male connector 1. The shell 3 is mounted on the outside of the male connector 1 to form a whole. At this time, the buckle 102 is in the protective plate 304, and the socket 101 extends out of the shell 3. The male connector 1 is protected by the shell 3, and the buckle 102 is protected by the protective plate 304.

[0033] Then as Figure 1 and Figure 2 As shown, at this time, the male plug 1 is not plugged in, and the two internal buckles 102 are close to the middle in an inverted V shape, but the limiting ring 301 is moved toward the direction of the connecting plate 302 by the external force, and the spring 303 is compressed. The limiting ring 301 is under the guard plate 304. At this time, the two guard plates 304 are slightly opened to both sides in a V shape without the abutment of the limiting ring 301, and the pressure column 305 of the limiting ring 301 is away from the buckle 102.

[0034] Then as Figure 3 and Figure 4 As shown, the female head 2 is inserted into the two buckles 102, and the buckles 102 are slightly opened to both sides. At this time, the male head 1 and the female head 2 are plugged in and fixed, and the limiting ring 301 is loosened. Under the action of the spring 303, the limiting ring 301 moves upward, and the limiting ring 301 will close the guard plate 304 opened to both sides, and the guard plate 304 approaches the direction of the buckle 102. At the same time, the pressure column 305 presses against the buckle 102. At this time, the guard plate 304 is pressed against the buckle 102 under the action of the limiting ring 301 to complete the locking of the buckle 102.

[0035] At the same time, the buckle 102 and the guard plate 304 are made of flexible plastic material to ensure that the buckle 102 and the guard plate 304 can be bent within a certain angle without breaking, so as to facilitate repeated plugging and use.

[0036] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
