[0022] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-5 As shown, a new energy photovoltaic connector that is anti-loosening and dustproof includes a female connector 1 and a female connector 2. The female connector 1 and the female connector 2 are connected by a snap fastener, and a protective mechanism is provided between the female connector 2 and the female connector 1.

[0024] The connecting head ring is a fixed connecting component in the protection mechanism. The connecting head ring is located on the plug end side of the sub-connector 2.

[0025] Telescopic cover head, the telescopic cover head is a connecting part and protective part in the protective mechanism. The telescopic cover head is set on the female connector 1 and is connected and matched with the connecting head ring.

[0026] The telescopic cover head consists of a fixed tail plate 3, a corrugated telescopic cover 31, and a threaded head 32. The fixed tail plate 3 is fixedly installed on the rear side of the female connector 1. The corrugated telescopic cover 31 is connected to the fixed tail plate 3 and is located on the connection side between the female connector 1 and the female connector 2. The threaded head 32 is rotatably and sealingly connected to the corrugated telescopic cover 31 and is matched with the threaded connection of the connector head ring.

[0027] When connecting the female connector 1 and the female connector 2 of the photovoltaic line into a wire harness, the female connector 1 and the female connector 2 are first initially connected by a snap fastener to achieve the wire harness connection. After that, the threaded head 32 in the telescopic cover is pulled to bring it close to the connecting head ring. Finally, the threaded head 32 is threadedly connected to the connecting head ring. At this time, the corrugated telescopic cover 31, together with the threaded head 32 and the fixed tail plate 3, forms a closed space between the connecting head ring and the fixed tail plate 3. The connecting head ring directly forms a closed shield for the female connector 2. In this way, the connection between the female connector 1 and the female connector 2 can be shielded and protected. At the same time, through the connection between the telescopic cover and the connecting head ring, when the snap fastener connection between the female connector 2 and the female connector 1 becomes loose or falls off, a certain degree of connection stability can be formed by the protection mechanism to avoid direct detachment and the resulting danger of exposed lines.

[0028] In other embodiments, a pull wire is provided between the threaded head 32 and the fixed tail plate 3. The flexibility of the pull wire itself can meet the interval changes between the threaded head 32 and the fixed tail plate 3. The rigidity of the pull wire itself can prevent the corrugated telescopic cover 31 from cracking due to its weak tensile strength, thereby further improving stability.

[0029] The connecting head ring consists of a rear connecting sleeve 4 and an internal threaded ring 41. The rear connecting sleeve 4 and the internal threaded ring 41 are integrally formed and are bonded to the connecting end of the sub-connector 2 after being sleeved. The vertical cross-section of the internal threaded ring 41 is U-shaped and the groove is provided with threads. The threaded head 32 matches the U-shaped structure of the internal threaded ring 41 and is threadedly connected to it.

[0030] The rear connecting sleeve 4 is used to connect with the sub-connector 2. During assembly, the rear connecting sleeve 4 can be directly inserted into the sub-connector 2 until the plug part of the sub-connector 2 is in the shielded area of ​​the internal thread ring 41. The rear connecting sleeve 4 can be bonded to the sub-connector 2, or it can be connected by compression.

[0031] The end of the threaded head 32 is provided with a sealing gasket.

[0032] After the threaded head 32 and the internal threaded ring 41 of the connecting head ring are connected, it can further achieve the effect of sealing and protecting, preventing external dust and rainwater from entering the connection area.

[0033] The corrugated telescopic cover 31 is an elastic structure and remains in a retracted state when at rest.

[0034] This allows the threaded head 32 to automatically reset after disengaging from the internal threaded ring 41, improving the ease of disassembly.

[0035] The buckle consists of a buckle ring 5 and a buckle plate 51. The buckle ring 5 is connected to the plug side of the female connector 1 and has symmetrically opened sockets 52. The number of buckle plates 51 corresponds to the number and position of the sockets 52. The buckle plate 51 is connected to the female connector 2 and is made of elastic plastic. The buckle plate 51 has an overall L-shaped structure and forms abutment limit with the sockets 52 in the silent state.

[0036] When connecting the female connector 1 and the female connector 2, insert the plug part of the female connector 2 into the female connector 1. At this time, the L-shaped structure of the buckle plate 51 is blocked by the structure of the socket 52 at the buckle ring 5. It will bend through its own elasticity until the buckle plate 51 is inserted into the socket 52 and extends out. Then the buckle plate 51 resets and cooperates with the buckle ring 5 to form abutment and block, thereby limiting the connection between the female connector 1 and the female connector 2. With the shielding of the protective mechanism, it can directly avoid the loosening caused by external influences. When disassembly is required, press the buckle plate 51 down with your fingers at the same time to make the buckle plate 51 bend and avoid the structural part of the buckle ring 5. At this time, pull the female connector 2 to make the buckle plate 51 retract into the socket 52 until it is completely detached. This connection is convenient, quick and stable.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
