Description

Technical Field

[0001] This utility model relates to the field of marine photovoltaic equipment technology, and in particular to a marine photovoltaic double-sealed double-clamp connector. Background Technology

[0002] The demand for offshore photovoltaic (PV) power is constantly growing, and the harsh environment of offshore power plants places higher demands on PV connectors. PV connectors are more susceptible to corrosion from water vapor and salt spray, as well as swaying from wind and waves, leading to problems such as leakage and damage. Existing PV connectors have an additional heat shrink tubing layer for sealing and protection outside the nut, and then an upper and lower shell layer. The two shells are fixed to the connector by ultrasonic welding. The upper and lower shells provide additional mating clips. The current PV connector sealing method is a single seal, that is, the sealing ring is sealed after the nut is tightened. The redundancy design is insufficient. At sea, the wind and waves are relatively large, and the connector is more prone to swaying. The single clip redundancy is not enough. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 9As shown, the positive connector 1 includes a positive terminal 11 and a positive pin 12 inserted into the positive terminal 11. The end of the positive pin 12 away from the mating structure 3 is connected to a positive wire harness 14 via a positive nut 13. The negative connector 2 includes a negative terminal 21 and a negative pin 22 inserted into the negative terminal 21. The end of the negative pin 22 away from the mating structure 3 is connected to a negative wire harness 24 via a negative nut 23. The positive nut 13 is connected to the positive terminal 11 via a threaded section. A sealing plug 4 is installed inside the positive nut 13 to abut against the end of the positive terminal 11. A sealing layer 5 covers the outside of the positive nut 13. The negative nut 23 is connected to the negative terminal 21 via a threaded section. A sealing plug 4 is installed on the inner side of the negative connector 23, which abuts against the end of the negative connector 21. A sealing layer 5 is covered on the outer side of the negative connector 23. The sealing plug and sealing layer in the positive connector and the negative connector have the same structure and installation method, forming a double sealing structure on the inner and outer sides of the connector. The positive connector 11 is connected to the negative connector 21 by a double-clawed connection with a staggered arrangement. The double-clawed connection improves the connection stability and can maintain a good connection in harsh marine environments, ensuring the stability and reliability of the connection. Without adding extra parts, the connection is more secure and reliable. The connector cannot be easily detached or loosened, which improves safety, reduces parts, reduces mold and material costs, simplifies assembly, and reduces assembly costs.

[0025] like Figure 3 The dual-claw configuration includes a first claw 111 located on the same side as the contact plane of the positive terminal connector 11's socket surface, and a second claw 112 offset from the first claw 111. At least two sets of the first claw 111 and the second claw 112 are provided, symmetrically distributed about the central axis of the positive terminal connector 11. Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, two sets of sealing rings 114 are provided at the root of the positive terminal connector 11. The first claw 111 and the second claw 112 are provided with an inclination angle on one side that deviates from the central axis of the positive terminal connector 11. The ends of the first claw 111 and the second claw 112 are provided with outward-folding buckles to ensure connection stability and prevent detachment.

[0026] like Figure 2 and Figure 6As shown, the positive electrode harness 14 passes through the positive electrode nut 13 and is electrically connected to the end of the positive electrode pin 12. The positive electrode pin 12 includes a positive electrode clamp 122 for fixing the positive electrode harness 14 and a positive electrode insertion section 121 on the side away from the positive electrode clamp 122. The positive electrode nut 13 is fixed to the positive electrode connector 11 by a threaded section. A positive limit flange 113 is provided on the side of the threaded section near the insertion structure 3. During the assembly process, the sealing plug is placed in the positive electrode nut. After the positive electrode clamp is fixed to the positive electrode harness, it is inserted into the inside of the positive electrode connector. The positive electrode nut with the sealing plug is tightened on the threaded section of the positive electrode connector end face to complete the fixation, so that the sealing plug abuts against the positive electrode connector, and the initial assembly is completed.

[0027] like Figure 2 , Figure 7 , Figure 8 and Figure 9 As shown, the negative terminal connector 21 is provided with a first slot 211 that matches the first claw 111 and a second slot 212 that matches the second claw 112. Both the first slot 211 and the second slot 212 are semi-open structures. The negative terminal wire harness 24 passes through the negative terminal nut 23 and is electrically connected to the end of the negative terminal pin 22. The negative terminal pin 22 includes a negative terminal clamp 222 for fixing the negative terminal wire harness 24 and a negative terminal insertion section 221 on the side away from the negative terminal clamp 222. The negative terminal nut 23 is fixed to the negative terminal connector 21 by a threaded section. A negative limit flange 213 is provided on the side of the threaded section near the insertion structure 3. During the assembly process, the sealing plug is placed in the negative terminal nut. After the negative terminal clamp is fixed to the negative terminal wire harness, it is inserted into the inside of the negative terminal connector. The negative terminal nut with the sealing plug is tightened on the threaded section of the end face of the negative terminal connector to complete the fixation, so that the sealing plug abuts against the negative terminal connector, and the initial assembly is completed.

[0028] After the positive and negative connectors are initially assembled, the positive connector and positive wire harness are coated with adhesive to cover the positive limit flange, positive nut, and part of the surface of the positive wire harness. The negative connector and negative wire harness are also coated with adhesive to cover the negative limit flange, negative nut, and part of the surface of the negative wire harness. After curing, the first claw of the positive connector is inserted into the first slot of the negative connector, and the second claw is then inserted into the second slot of the negative connector, thus completing the connector assembly.

[0029] In one embodiment of this application, the sealing layer 5 is coated with a TPV encapsulation structure on the outside of the positive and negative terminals to form a good sealing layer.

[0030] Another embodiment of this application differs from the above embodiments in that the overmolding structure can be replaced by heat shrink tubing, further reducing costs while ensuring sealing.

[0031] Several points need to be clarified: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly, and can refer to mechanical or electrical connections, or internal connections between two components, or direct connections.
