Description

Technical Field

[0001] This utility model relates to the field of photovoltaic connector technology, and specifically to a protective device. Background Technology

[0002] A photovoltaic (PV) connector is an electrical interface component that connects PV modules to an inverter. PV connectors play a crucial role in PV power generation systems, directly affecting the smooth transmission of DC power generated by the PV modules to the inverter for conversion. A PV connector includes a socket and a plug. The socket has symmetrical slots on both sides, with through holes between the slots and the ends of the socket. The plug has a locking mechanism that passes through the through holes and engages with the slots. Operators manually press the locking mechanism towards the center to separate the socket from the plug. However, during use, operators may accidentally touch the locking mechanism, or the mechanism may collide with surrounding structures, causing the socket and plug to separate.

[0003] A tamper-proof electrical connector is disclosed in the prior art, such as Figures 1-2 As shown, the electrical connector includes a socket 01 and a plug 02. One end of the plug 02 has symmetrically arranged first locking heads 021 extending toward the socket 01 on both sides. The socket 01 has symmetrically arranged first locking grooves 011 on both sides that mate with the first locking heads 021. Anti-tamper buckles 03 are detachably installed on both sides of the socket 01. The anti-tamper buckles 03 are covered on the outside of the first locking grooves 011 to prevent accidental contact with the first locking heads 021 from causing the socket 01 and plug 02 to detach, thus achieving the function of anti-tamper protection.

[0004] However, if the anti-tamper clip 03 is too close to the socket 01, it will be difficult to separate the socket 01 from the plug 02. If the anti-tamper clip 03 is too close to the socket 01, the anti-tamper clip 03 will easily come into contact and fall off. Utility Model Content
