[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. Since the voltage at the power output port is high and the current is strong, the photovoltaic system mostly adopts a plug-and-play connector at present. The existing connector generally includes a plug and a socket. A buckle is arranged on the plug, and a fixing groove is arranged on the socket. The buckle includes an elastic arm and a protrusion arranged on the elastic arm. The protrusion is clamped in the fixing groove through the elasticity of the elastic arm, so as to realize the locking of the plug and the socket. If it is necessary to remove the plug, the unlocking handle at the end of the elastic arm can be pressed to make the protrusion leave the fixing groove, that is, to unlock the plug and the socket, and then the plug can be pulled out from the socket.

[0003] The above-mentioned connector can be opened by hand, which is likely to cause misoperation and further lead to electric shock accidents. Therefore, the connector needs to be protected to prevent on-site personnel from opening it randomly. In the prior art, the protection devices are basically one-to-one protection, that is, one protection device corresponds to one plug. When multiple plugs are installed on one socket, a protection device needs to be installed for each plug, and the installation process is cumbersome and the efficiency is low.

[0004] The information disclosed in this background art section is only for increasing the understanding of the overall background of the utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art.

[0029] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0030] As Figures 1 to 4 shown, a connector assembly in an embodiment of the present utility model includes a connector protection device 1 and a connector 2; the connector 2 includes a socket 21 and a plug 22 that are inserted into each other, a first locking portion 211 is provided on the socket 21, an unlocking handle 221 is provided on the plug 22, a second locking portion 222 that cooperates with the first locking portion 211 is provided on the unlocking handle 221, a limiting hole 212 is provided on the socket 21, and a rib 223 is provided on the plug 22; the connector protection device 1 includes a housing 11 and a limiting mechanism 12, a receiving groove 111 for receiving the unlocking handle 221 and a sliding groove 112 extending in a first direction are provided on the housing 11, and the sliding groove 112 is used for sliding connection with the rib 223 to limit the housing 11 and the connector 2 in a second direction; the limiting mechanism 12 is provided on the housing 11, and the limiting mechanism 12 is used for inserting into the limiting hole 212 on the socket 21 in the second direction to limit the housing 11 and the connector 2.

[0031] It can be understood that the connector 2 assembly of the present utility model has a receiving groove 111 provided on the cover body 11. The receiving groove 111 can be used to accommodate one or more unlocking handles 221, thereby protecting the unlocking handles 221 and preventing accidental touch. By inserting the limiting mechanism 12 into the limiting hole 212 along the second direction, it can limit the cover body 11 and the connector 2 in other directions except the second direction. Then, through the sliding groove 112 for sliding connection with the rib 223, it can limit the cover body 11 and the connector 2 in the second direction, playing a role in restricting the corresponding positions between the cover body 11 and the connector 2, so as to achieve the position where the cover body 11 completely covers the unlocking handle 221, the first locking portion 211, and the second locking portion 222 on the connector 2. When the connector protection device 1 is in the locked state (i.e., the second state), the unlocking handle 221 cannot be pressed to unlock the plug 21 and the socket 22, thus realizing the function of secondary locking. Since the limiting mechanism 12 is inserted into the limiting hole 212 on the socket 21, and one sliding groove 112 can be slidably connected with multiple ribs 223, therefore, one receiving groove 111 can accommodate multiple unlocking handles 221, thereby improving the installation and disassembly efficiency of the connector protection device 1 and the connector 2. For example, in this embodiment, two plugs 22 can be inserted into one socket 21, one receiving groove 111 can accommodate two unlocking handles 221, and one sliding groove 112 is slidably connected with two ribs 223.

[0032] In this embodiment, the first direction and the second direction are perpendicular to each other, that is, the first direction is Figure 1 and Figure 3 the y - direction in Figure 1 and Figure 3 the x - direction in Figure 1 and Figure 3 the z - direction in

[0033] Specifically, in the first state, the limiting mechanism 12 is separated from the limiting hole 212, and the connector protection device 1 and the connector 2 are slidably connected along the first direction; in the second state, the limiting mechanism 12 is inserted into the limiting hole 212 on the connector 2, and the connector protection device 1 and the connector 2 are fixed in the first direction. Among them, the installation process of the connector protection device 1 and the connector 2 first experiences the first state and then is converted to the second state.

[0034] Such as Figure 2As shown, in this embodiment, the limiting mechanism 12 includes a limiting member 121 and a fixing member 122 that are movably connected, and the fixing member 122 is fixedly installed on the cover 11. That is, the limiting member 121 is movably installed on the fixing member 122 and thus installed on the cover 11.

[0035] Preferably, the limiting member 121 is a bolt and the fixing member 122 is a nut. Through the threaded connection of the bolt and the nut and the fact that the nut is fixedly installed on the cover 11, the limiting member 121 can move along the second direction on the cover 11, that is, the insertion and separation of the limiting member 121 and the limiting hole 212 are realized.

[0036] Further, the cover 11 is provided with a mounting hole 113, the fixing member 122 is in interference fit with the mounting hole 113, the cover 11 is provided with a through hole 114 that penetrates along the second direction, the through hole 114 is used to install the limiting member 121, and the through hole 114 is communicated with the mounting hole 113.

[0037] Among them, a limiting surface 1141 for abutting against the head of the bolt can be provided on the inner wall of the through hole 114, so as to limit the bolt from moving out of the through hole 114 along the insertion direction, and also enhance the connection strength between the bolt and the cover 11.

[0038] In other embodiments, the limiting member 121 and the fixing member 122 can be a sleeve and a sliding rod sleeved with each other (not shown in the figure), and engaging portions that are engaged with each other are respectively provided on the outer surface of the sliding rod and the inner wall of the sleeve, so as to realize the clamping of the limiting member 121 sliding to a specific position on the fixing member 122. The specific position can be considered as the relative position between the limiting member 121 and the fixing member 122 when the limiting member 121 is inserted into the limiting hole 212.

[0039] As Figure 3 shown, a supporting portion 115 protrudes from the inner wall of the receiving groove 111, and the supporting portion 115 is used to limit the unlocking handle 221 in the receiving groove 111. Along the third direction, a limiting space 117 is formed between the supporting portion 115 and the inner wall of the receiving groove 111, and at least part of the unlocking handle 221 is located in the limiting space 117, so as to limit the unlocking handle 221.

[0040] As Figure 3 shown, a limiting portion 116 protrudes from the inner wall of the receiving groove 111. Along the first direction, the limiting portion 116 is used to abut against the unlocking handle 221. Along the first direction, the limiting portion 116 being used to abut against the unlocking handle 221 can play a role in positioning the cover 11 during the installation process. At this time, the limiting mechanism 12 is aligned or substantially aligned with the limiting hole 212, which is convenient for the insertion of the limiting mechanism 12 and the limiting hole 212.

[0041] As Figure 4As shown, in this embodiment, the second locking portion 222 is a latch protruding from the unlocking handle 221, and the first locking portion 211 is a slot. The latch is engaged with the slot to lock the socket 21 and the plug 22.

[0042] Specifically, the insertion direction of the plug 22 and the socket 21 is the same as the insertion direction of the limiting mechanism 12 and the limiting hole 212, that is, the insertion direction of the plug 22 and the socket 21 is the same as the second direction.

[0043] 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.
