[0002] In a photovoltaic system, a photovoltaic panel generates electricity by converting solar energy. When the photovoltaic panel is exposed to sunlight, the photovoltaic system is in a live state. Due to the high voltage and strong current at the power output port, currently, most photovoltaic systems adopt plug-and-play connectors. Existing connectors generally include a plug and a socket. A buckle is provided on the plug, and a fixing groove is provided on the socket. The buckle includes an elastic arm and a protrusion provided on the elastic arm. The protrusion is snapped into the fixing groove through the elasticity of the elastic arm, thereby realizing the locking of the plug and the socket. If the plug needs to be removed, the unlocking handle at the end of the elastic arm can be pressed to make the protrusion leave the fixing groove, that is, unlock the plug and the socket, and then pull out the plug from the socket.

[0028] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0029] Such as Figures 1 to 4As shown in the figure, a connector assembly in an embodiment of the present utility model includes a connector 2 and a connector protection device 1; the connector 2 includes a socket 21 and a plug 22 that are inserted into each other. The socket 21 is provided with a first locking portion 211, the plug 22 is provided with an unlocking handle 221, and the unlocking handle 221 is provided with a second locking portion 222 that cooperates with the first locking portion 211. A fixing member 23 is provided on the socket 21 and / or the plug 22; the connector protection device 1 includes a cover body 11 and a fastening member 12. The cover body 11 is provided with a receiving groove 111 for receiving the unlocking handle 221 on the connector 2; the fastening member 12 is provided on the cover body 11, and the fastening member 12 can be connected to the fixing member 23 to lock the cover body 11 to the connector 2.
[0030] It can be understood that after the socket 21 and the plug 22 are inserted, the first locking portion 211 is connected to the second locking portion 222, and generally a part of the unlocking handle 221 will be exposed. In order to prevent accidental contact from causing accidents, at this time, the cover body 11 can be installed on the connector 2 so that the unlocking handle 221 is received in the receiving groove 111, thereby protecting the unlocking handle 221.
[0031] One or more plugs 22 can be inserted into one socket 21, and one or more receiving grooves 111 are provided on one cover body 11. In this embodiment, two plugs 22 are inserted into one socket 21, and two receiving grooves 111 are provided on one cover body 11. There is only one fastening member 12, that is, only one fastening member 12 can fixedly install one cover body 11 on the connector 2 and protect the unlocking handles 221 on the two plugs 22; improving the installation and disassembly efficiency of the connector protection device 1.
[0032] Among them, the socket 21 can be provided with one or more first locking portions 211. In this embodiment, the socket 21 can be provided with two first locking portions 211. At this time, the first locking portions 211 and the second locking portions 222 can be in one-to-one correspondence; the first locking portion 211 can be a card slot, and the second locking portion 222 can be a card block provided on the unlocking handle 221. Through the clamping connection of the card block and the card slot, the locking of the socket 21 and the plug 22 is realized. The material of the unlocking handle 221 is an existing elastic material.
[0033] The fixing member 23 can be fixedly installed on the plug 22 or on the socket 21. As Figure 4 shown, in this embodiment, the fixing member 23 is installed on the socket 21.
[0034] Specifically, the cover 11 and the connector 2 are plugged in the first direction to receive the unlocking handle 221 in the receiving groove 111. The plugging direction of the plug 22 and the socket 21 is the same as the first direction. That is, along the first direction, the cover 11 is installed on the connector 2, and the cover 11 is restricted and installed on the connector 2 through the cooperation of the fastener 12 and the fixing member 23.
[0035] As Figure 1 and 4 shown, a rib 223 is provided on the outer surface of the plug 22; along the second direction, the inner wall of the receiving groove 111 abuts against the rib 223 on the connector 2. That is, when the cover 11 is installed on the connector 2 along the first direction, the abutment of the two ends of the rib 223 along the second direction and the inner wall of the receiving groove 111 along the second direction can limit and guide the relative positional relationship between the cover 11 and the connector 2, and can also align the fastener 12 with the fixing member 23, facilitating the connection between the fastener 12 and the fixing member 23; that is, the receiving groove 111 not only functions to receive the unlocking handle 221, but also plays a role in the installation and positioning of the cover 11. The locked state is the state when the connector protection device 1 is locked with the connector 2.
[0036] In this embodiment, a protrusion 112 is provided on the inner wall of the receiving groove 111; along the first direction, the protrusion 112 is provided with an abutting surface 113 for abutting against the rib 223. Such a setting is to pre-install the cover 11 on the connector 2 under specific use environments.
[0037] For example, when the socket 21 is at the top in the vertical direction, that is, the plug 22 is plugged into the socket 21 from bottom to top in the vertical direction. At this time, the operator can install the cover 11 on the plug 22 along the first direction and make the abutting surface 113 of the protrusion 112 abut against the rib 223, which can play a role in hanging the cover 11 on the plug 22, serving as a support for the cover 11 and for pre-assembling (pre-installing) the cover 11.
[0038] Furthermore, along the first direction, the protrusion 112 is provided with a guiding surface 114 opposite to the abutting surface 113. The guiding surface 114 is not perpendicular to the first direction; the protrusion 112 can be an elastic protrusion 112, that is, it can undergo a certain amount of elastic deformation. That is, during the process of installing the cover 11 on the connector 2 along the first direction, the guiding surface 114 on the protrusion 112 first abuts against the rib 223, and then the guiding surface 114 converts the force in the first direction given by the rib 223 into a force in other directions and causes a certain amount of elastic deformation of the protrusion 112, so as to cross over the rib 223. The guiding surface 114 plays a role in facilitating the installation of the cover 11 and the connector 2.
[0039] As Figures 2 to 4As shown, in this embodiment, the fastener 12 is provided with an external thread for threaded connection with the threaded hole of the fixing member 23. That is, the connection between the fastener 12 and the fixing member 23 is achieved through threaded connection. At this time, the fastener 12 can be rotatably mounted on the cover 11, and the fixing member 23 can be fixedly mounted on the connector 2, so as to realize the locking (fixing) of the cover 11 and the connector 2.
[0040] Preferably, the cover 11 can be provided with a mounting hole 115 for accommodating the fastener 12, which can prevent others from accidentally touching the fastener 12 and causing the cover 11 to be separated from the connector 2.
[0041] Preferably, the fastener 12 is a screw and the fixing member 23 is a nut. The screw rod of the screw is threadedly connected with the thread to realize the locking (fixing) of the cover 11 and the connector 2. Specifically, in the locked state, along the first direction, the cover 11 is clamped between the fastener 12 and the socket 21.
[0042] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
