Photovoltaic connectors are important components in solar photovoltaic power generation systems. They are used to connect multiple solar cell modules into a system. They are composed of male and female connectors and can be easily plugged in and out. Due to the harsh environment in which photovoltaic connectors are located, they have extremely high requirements for connection stability and their own sealing.

[0003] However, the existing photovoltaic connectors have the following defects: At present, most photovoltaic connectors insert the cable into the shell, and the cable is provided with a sealing ring, claws and nuts.

Photovoltaic connectors of this structure are prone to problems of decreased connection stability and self-sealing after long-term use in harsh operating environments. In addition, the shell of the photovoltaic connector is sealed by a snap-fit ​​sealing ring, which is also prone to the above-mentioned problems. Summary of the invention

[0035] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0037] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0038] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0039] The present application is further described below with reference to the accompanying drawings:

[0040] like Figures 1 to 7As shown, the present application provides a photovoltaic connector protective cover, including a first shell 1 and a second shell 2, the first shell 1 is provided with a first accommodating groove 11, and the second shell 2 is provided with a second accommodating groove 21, the first accommodating groove 11 and the second accommodating groove 21 are suitable for cooperating to form a cavity for accommodating the photovoltaic connector to seal and protect the electrical performance of the photovoltaic connector.

[0041] The first shell 1 and the second shell 2 are respectively provided with a coupling groove 12 and a coupling portion 22 on the side around the first accommodating groove 11 and the second shell 2 are provided with a coupling groove 12 and a coupling portion 22 on the side around the second accommodating groove 21. The shape of the coupling portion 22 is designed to match the coupling groove 12 so that the two can be more tightly fitted and connected. When the coupling groove 12 and the coupling portion 22 are tightly fitted, a certain sealing effect can be achieved.

[0042] In some embodiments, the coupling groove 12 and the coupling portion 22 are fitted together to minimize the gap therebetween, thereby achieving a sealing effect.

[0043] like Figure 3 In the illustrated embodiment, the first housing 1 is provided with a coupling groove 12 around the first receiving groove 11 to improve the sealing performance of the entire receiving cavity.

[0044] like Figure 4 In the illustrated embodiment, the second housing 2 is provided with a coupling portion 22 around the second receiving groove 21 to enhance the sealing performance of the entire receiving cavity.

[0045] The first shell 1 and the second shell 2 are respectively provided with a fixing groove 23 and a fixing portion 13, which are used to connect with each other and limit the separation of the first shell 1 and the second shell 2, so that the combination groove 12 and the combination portion 22 remain engaged to ensure the sealing performance of the two.

[0046] In some embodiments, the fixing groove 23 is a bayonet, and the fixing portion 13 is a buckle, so that the fixing groove 23 and the fixing portion 13 can be detachably connected, which facilitates the combination and separation of the first shell 1 and the second shell 2.

[0047] like Figure 4 In the illustrated embodiment, the fixing groove 23 protrudes from the side surface of the second shell 2, so that the fixing groove 23 can be easily operated using tools such as needle-nosed pliers, etc., to help the fixing portion 13 to be disengaged, thereby reducing the difficulty of disassembly and assembly.

[0048] In some embodiments, there are multiple fixing grooves 23 and fixing portions 13, and the fixing grooves 23 and fixing portions 13 are arranged at intervals along the circumference of the combining grooves 12 and the combining portions 22, respectively, so that the combining grooves 12 and the combining portions 22 can be tightly combined at all positions, thereby improving the overall combining stability of the first shell 1 and the second shell 2.

[0049] like Figure 6 In the illustrated embodiment, when the first shell 1 and the second shell 2 are combined with each other, the combining groove 12 and the combining portion 22 are suitable for being fitted with each other, and the fitting portion is filled with a combining medium 3 to seal the combining groove 12, and the fixing groove 23 and the fixing portion 13 are suitable for being connected with each other and limiting the combining portion 22 from being separated from the combining groove 12, and the combining medium 3 can fill the gap that may be present when the combining groove 12 and the combining portion 22 are fitted with each other, thereby further improving the tightness and sealing of the combining groove 12 and the combining portion 22.

[0050] In some embodiments, the bonding medium 3 is pre-filled in the bonding groove 12 before the bonding groove 12 and the bonding portion 22 are bonded. During the process of the bonding portion 22 and the bonding groove 12 being engaged, the bonding medium 3 can be squeezed so that the bonding medium 3 can automatically fill the gap between the bonding groove 12 and the bonding portion 22.

[0051] In some embodiments, the bonding medium 3 preferably uses waterproof sealant such as butyl rubber, which can have a certain viscosity after curing, thereby ensuring the tightness of the bonding between the bonding groove 12 and the bonding part 22 while improving the sealing and waterproof properties.

[0052] In some embodiments, the photovoltaic connector protective cover further includes a barrier 4, and the first shell 1 and the second shell 2 are isolated by the barrier 4 before being combined, to ensure that the first shell 1 and the second shell 2 are not accidentally combined before installation, which is convenient for handling and transportation.

[0053] In some embodiments, the barrier 4 is preferably made of non-stick paper to prevent the binding medium 3 from transferring to the barrier 4 after the barrier 4 and the binding medium 3 are released, resulting in the loss of the binding medium 3 in the binding groove 12, thereby affecting the sealing and waterproof properties of the binding groove 12 and the binding part 22.

[0054] In some embodiments, an elastic rope may be wrapped around the outside of the first shell 1 and the second shell 2 to bind them, so that the first shell 1 and the second shell 2 can stably clamp and fix the blocking member 4 .

[0055] like Figure 7 In the illustrated embodiment, the fixing portion 13 is disposed at both ends and both sides of the first shell 1 and is located on the outside of the coupling groove 12, so that the barrier 4 can cover the coupling groove 12 while playing a role in stabilizing and limiting the movement of the barrier 4, thereby reducing the probability of the barrier 4 detaching and falling, and improving the stability during transportation.

[0056] like Figure 4 and 6In the embodiment shown, at least one first protrusion 221 is provided on the top of the coupling portion 22, and the first protrusion 221 is arranged along the length direction of the coupling portion 22. It can be understood that since the coupling portion 22 is arranged around the second accommodating groove 21, the first protrusion 221 can follow the coupling portion 22 and be arranged around the second accommodating groove 21. When the coupling portion 22 is engaged and connected with the coupling groove 12, the first protrusion 221 can contact along the coupling groove 12, thereby improving the sealing between the coupling portion 22 and the coupling groove 12, blocking the cavity, and thus improving the sealing.

[0057] like Figure 6 In the illustrated embodiment, when the coupling portion 22 is engaged with the coupling groove 12, an overflow gap 5 is formed between the coupling portion 22 and the coupling groove 12 on both sides of the first protrusion 221. The coupling portion 22 can push the coupling medium 3 to both sides for filling through the first protrusion 221, thereby increasing the flow of the coupling medium 3, improving the filling solidity, and avoiding the reduction of sealing due to the generation of cavities.

[0058] In some embodiments, the first protrusion 221 can be a sealing strip, which is embedded in the top of the connecting portion 22. Since the sealing strip has a certain elastic deformation ability, when the connecting groove 12 and the connecting portion 22 are engaged, the sealing strip can contact the connecting groove 12 to achieve a first seal, and the filling medium can form a second seal. The two sealing structures can effectively improve the sealing and waterproof performance between the connecting groove 12 and the connecting portion 22, and the sealing strip can help promote the flow of the connecting medium 3.

[0059] In some embodiments, the sealing strip is made of rubber.

[0060] like Figure 1 In the illustrated embodiment, a first wire groove 14 is provided on the first shell 1, and a second wire groove 24 is provided on the second shell 2. The first wire groove 14 and the second wire groove 24 are suitable for cooperating to form a wire hole, and the wire hole connects the cavity and the outside of the photovoltaic connector protective cover. In order to avoid water leakage at the wire hole, the first wire groove 14 and / or the second wire groove 24 are suitable for covering the bonding medium 3. The bonding medium 3 can fill the gap between the wire and the wire hole, thereby achieving sealing and waterproofing.

[0061] like Figure 3 and 4 In the illustrated embodiment, fixing portions 13 are provided on both sides of the first wire groove 14, and fixing grooves 23 are provided on both sides of the second wire groove 24. These fixing portions 13 and fixing grooves 23 can improve the stability of the wire holes formed by the first wire groove 14 and the second wire groove 24, and reduce the probability of the first wire groove 14 and the second wire groove 24 loosening and separating.

[0062] In some embodiments, the coupling groove 12 passes through the first wire groove 14 or the second wire groove 24 .

[0063] like Figure 3 and 4 In the illustrated embodiment, the combining groove 12 passes through the first wire groove 14, and the combining portion 22 is connected with the second wire groove 24, so that the combining medium 3 in the combining groove 12 and the first wire groove 14 can be continuously filled, thereby reducing the difficulty of production and processing. When the combining portion 22 is combined with the combining groove 12, the first wire groove 14 and the second wire groove 24 can also be combined with the wire material together, thereby realizing the surrounding overall sealing of the cavity, and avoiding the occurrence of glue breakage between the combining groove 12 and the first wire groove 14, resulting in insufficient sealing.

[0064] like Figure 4 In the illustrated embodiment, at least one second protrusion 15 is circumferentially arranged in the first wire groove 14 and / or the second wire groove 24 .

[0065] In some embodiments, when the second protrusion 15 is provided in both the first wire groove 14 and the second wire groove 24, the second protrusion 15 in the first wire groove 14 and the second protrusion 15 in the second wire groove 24 can cooperate to form an annular structure, thereby interfering with the circumference of the wire in the wire hole, thereby improving the sealing performance. In addition, the annular structure can also squeeze the bonding medium 3 in the wire hole, reduce the appearance of cavities, and increase the filling degree.

[0066] It is understandable that the more the number of the second protrusions 15 is, the better the sealing effect is, and the better the filling degree of the bonding medium 3 is improved. It can be set according to actual needs, such as Figure 3 As shown, the second protrusions 15 may be arranged at intervals perpendicular to the axial direction of the wire hole along the axial direction of the wire hole.

[0067] The joining portion 22 is an edge portion formed by the first shell 1 on the periphery of the first accommodating groove 11 or an edge portion formed by the second shell 2 on the periphery of the second accommodating groove 21, that is, the joining portion 22 is a partial structure of the first shell 1, and the joining portion 22 and the first shell 1 form a whole, so that the joining portion 22 can obtain higher structural strength, reduce the probability of aging and deformation of the joining portion 22, and improve stability in long-term use.

[0068] like Figures 8 to 11 As shown, the present application provides a method for producing a photovoltaic connector protective cover, comprising the steps of:

[0069] S100, placing the first shell 1 and the second shell 2 on a glue-spraying jig 6;

[0070] S200, installing the glue-spraying jig 6 on the glue-spraying device 7, setting a program, and the glue-spraying device 7 automatically glues the coupling groove 12, the first wire groove 14, and the second wire groove 24;

[0071] S300, before the glue solidifies, the first shell 1 and the second shell 2 are combined in a form of isolation by the barrier 4, and tied and fixed;

[0072] S400, regularly check the glue application amount. If the glue application amount in the combination slot 12, the first wire slot 14 and the second wire slot 24 is abnormal, stop applying glue, check the equipment and adjust the glue application amount.

[0073] S500, regularly check the waterproof performance, assemble and combine the first shell 1 and the second shell 2, and then place them in a fixed water depth for a set time and then open them to observe whether water has entered.

[0074] The sealing performance of the photovoltaic connector protective cover produced by the above method can be significantly improved, and the protection level can reach the IP68 standard.

[0075] A plurality of fixing stations 61 may be provided on the gluing jig 6 for accommodating and fixing a plurality of first shells 1 and a plurality of second shells 2 .

[0076] In some embodiments, the gluing device 7 is at least suitable for the gluing head and the gluing fixture 6 thereon to move relative to each other on the X, Y, and Z axes.

[0077] Specifically, the glue-spraying device 7 includes an operating table 71, a movable seat 72, a movable mechanism 73 and a glue-spraying device 74. The glue-spraying jig 6 is suitable for being fixedly arranged on the movable seat 72, and the movable seat 72 is suitable for making the glue-spraying jig 6 move along the X-axis direction (such as Figure 8 The glue device 74 is arranged on the movable mechanism 73, and the movable mechanism 73 is suitable for making the glue device 74 move along the Y-axis and Z-axis directions (as shown in FIG. Figure 8 ) activities.

[0078] In some embodiments, the operating table 71 is suitable for moving the movable seat 72 along the X-axis direction (such as Figure 8 ) to move, thereby driving the glue-spraying fixture 6 along the X-axis direction (as shown in Figure 8 ) activities.

[0079] like Figure 8 In the illustrated embodiment, the glue applying device 74 includes a glue storage tank 741 , a cylinder 742 and a glue hose 743 . The glue storage tank 741 is used to deliver glue to the glue hose 743 , and the cylinder 742 is used to control the glue output and the glue applying speed.

[0080] like Fig. 9 In the illustrated embodiment, a positioning column 721 may be provided on the movable seat 72, and a positioning hole 62 may be provided on the gluing jig 6, so that the gluing jig 6 can be positioned in coordination with the positioning column 721 on the movable seat 72 through the positioning hole 62, thereby improving the accuracy of the gluing operation and the stability of the gluing amount.

[0081] like Fig.10 In the illustrated embodiment, the movable mechanism 73 realizes relative movement between the operating table 71 and the glue applying device 74 through guide rails arranged along the Y-axis and Z-axis directions.

[0082] like Figure 8 In the illustrated embodiment, there are multiple gluing devices 74, and the spacing between the gluing devices 74 can be set in accordance with the spacing between the fixed workstations 61 on the gluing jig 6, thereby enabling multi-station gluing operations and improving gluing efficiency.

[0083] It can be understood that by setting up two gluing devices 74 and two gluing jigs 6, the gluing devices 74 and the gluing jigs 6 are set in coordination with each other, one gluing jig 6 is suitable for placing the first shell 1, and the other gluing jig 6 is suitable for placing the second shell 2, so that the first shell 1 and the second shell 2 can be glued synchronously, thereby controlling the gluing error and making the gluing effects of the first shell 1 and the second shell 2 of the same group as consistent as possible.

[0084] Furthermore, an adjustment mechanism 75 is provided between the movable mechanism 73 and the gluing device 74 , and the adjustment mechanism 75 can make small adjustments to the gluing device 74 in the directions of the X, Y, and Z axes, so that the gluing errors of the multiple gluing devices 74 are close.

[0085] like Fig.11 In the illustrated embodiment, the adjustment device includes a plurality of adjustment blocks 751 and adjustment bolts 752 . The adjustment blocks 751 and the adjustment bolts 752 are arranged in a one-to-one correspondence. The adjustment bolts 752 can adjust the relative positions between the adjustment blocks 751 and lock the positions of the adjustment blocks 751 .

[0086] In step S300, the non-stick paper can also play a certain role in preventing the glue from solidifying, ensuring that after the non-stick paper is detached, the first shell 1 and the second shell 2 can be bonded together by the glue.

[0087] Specifically, in step S500, after being placed in water at a depth of 1 meter for 2 hours using a special testing device, the protective cover is opened to observe whether water has entered.

[0088] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application.
