Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic accessories, and in particular to a photovoltaic connector protective cover. Background Art

[0002] With the continuous improvement of people's living standards, solar photovoltaic power generation systems are developing rapidly. 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, extremely high requirements are placed on the stability of the connection and the sealing of the connector itself.

[0003] However, the existing photovoltaic connectors have the following defects: At present, the shells of most photovoltaic connectors are sealed by snap-fitting sealing rings. In harsh operating environments, after long-term use, the connection stability and sealing performance may deteriorate due to aging of the sealing rings. Once the above problems occur, the entire solar junction box needs to be replaced, which is cumbersome and costly. Summary of the Invention

[0004] One purpose of the present application is to provide a photovoltaic connector protective cover with a stable structure and good sealing effect.

[0005] In order to achieve the above objectives, the technical solution adopted in the present application is: a photovoltaic connector protective cover, comprising a first shell and a second shell, the first shell having a first combining side, the second shell having a second combining side, the first combining side and the second combining side being suitable for combining with each other, a combining groove and a combining portion being respectively provided on the first combining side and the second combining side, a fixing groove and a fixing portion being respectively provided on the first combining side and the second combining side, when the first combining side and the second combining side are combined with each other, the combining groove and the combining portion are suitable for mutual engagement and sealing, the fixing groove and the fixing portion are suitable for mutual connection and limiting the combining portion from being separated from the combining groove.

[0006] In some embodiments, a coupling medium is provided in the coupling groove, and the coupling medium is suitable for sealing when the coupling groove and the coupling portion are engaged with each other; the coupling medium is pre-filled in the coupling groove before the coupling groove and the coupling portion are coupled; and a barrier is also included, and the first shell and the second shell are isolated by the barrier before being coupled.

[0007] In some embodiments, at least one first protrusion is provided on the top of the coupling portion, and the first protrusion is arranged along the length direction of the coupling portion; when the coupling portion is embedded in the coupling groove, the coupling portion forms an overflow gap on both sides of the first protrusion and the coupling groove; the first protrusion is a sealing strip, and the sealing strip is embedded in the top of the coupling portion.

[0008] In some embodiments, there are a plurality of the fixing grooves and the fixing portions, and the fixing grooves and the fixing portions are spaced apart along the circumferences of the combining grooves and the combining portions, respectively.

[0009] In some embodiments, at least one first accommodating groove is provided on the first combining side, and at least one second accommodating groove is provided on the second combining side. When the first combining side and the second combining side are combined with each other, the first accommodating groove and the second accommodating groove are suitable for matching one by one to form a accommodating cavity, and the combining groove and the combining part are respectively arranged on the peripheral sides of the first accommodating groove and the second accommodating groove.

[0010] In some embodiments, at least one first wire groove is provided on the first combining side, and at least one second wire groove is provided on the second combining side. When the first combining side and the second combining side are combined with each other, the first wire groove and the second wire groove are suitable for matching one by one to form a wire hole, and the wire hole connects the cavity and the outside of the photovoltaic connector protective cover.

[0011] In some embodiments, the coupling groove passes through the first wire groove or the second wire groove.

[0013] In some embodiments, at least one second protrusion is circumferentially provided in the first wire groove and / or the second wire groove.

[0014] In some embodiments, the coupling portion is an edge portion formed by the first shell on a circumferential side of the first accommodating groove or an edge portion formed by the second shell on a circumferential side of the second accommodating groove.

[0015] Compared with the prior art, the beneficial effect of the present application is that the photovoltaic module connector protective cover of the present application optimizes the traditional sealing ring sealing scheme into a sealing scheme of the bonding groove and the bonding part. Since the shell of the photovoltaic module connector protective cover itself has higher structural strength than the sealing ring, the sealing scheme of the bonding groove and the bonding part can have higher structural stability during long-term use compared with the sealing ring scheme, and is not prone to deformation and loosening, resulting in a decrease in sealing performance. At the same time, the setting of the fixing groove and the fixing part can further improve the bonding stability and sealing of the bonding groove and the bonding part, thereby improving the service life.

[0027] The terms "comprises" 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 that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0028] The present application will be further described below with reference to the accompanying drawings:

[0029] like Figures 1 to 7 As shown, the present application provides a photovoltaic connector protective cover, including a first shell 1 and a second shell 2, the first shell 1 has a first bonding side 16, the second shell 2 has a second bonding side 25, the first bonding side 16 and the second bonding side 25 are suitable for bonding to each other, the first bonding side 16 and the second bonding side 25 are respectively provided with a bonding groove 12 and a bonding portion 22, the first bonding side 16 and the second bonding side 25 are respectively provided with a fixing groove 23 and a fixing portion 13, when the first bonding side 16 and the second bonding side 25 are combined with each other, the bonding groove 12 and the bonding portion 22 are suitable for mutual engagement and sealing, the fixing groove 23 and the fixing portion 13 are suitable for mutual connection, and limit the bonding portion 22 from being separated from the bonding groove 12.

[0030] A coupling medium 3 is provided in the coupling groove 12 , and the coupling medium 3 is suitable for sealing when the coupling groove 12 and the coupling portion 22 are engaged with each other.

[0031] The first shell 1 is provided with a first accommodating groove 11 on the first combining side 16, and the second shell 2 is provided with a second accommodating groove 21 on the first combining side 16. The first accommodating groove 11 and the second accommodating groove 21 are suitable for cooperating to form a cavity for accommodating a photovoltaic connector to seal and protect the electrical performance of the photovoltaic connector.

[0032] The first shell 1 is provided with a coupling groove 12 and a coupling portion 22 on the first coupling side 16 and the second shell 2 is provided with a coupling portion 22 on the second coupling side 25 respectively. The shape of the coupling portion 22 is designed to match the coupling groove 12 so that the two can be closely fitted together. When the coupling groove 12 and the coupling portion 22 are tightly fitted together, a certain sealing effect can be achieved.

[0033] In some embodiments, the coupling groove 12 and the coupling portion 22 are in a resistive fit to minimize the gap therebetween, thereby achieving a sealing effect.

[0034] 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.

[0035] 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.

[0036] The first shell 1 is provided with a fixing groove 23 and a fixing portion 13 on the first bonding side 16 and the second shell 2 is provided with a fixing groove 23 and a fixing portion 13 on the second bonding side 25, respectively. The fixing groove 23 and the fixing portion 13 are used to connect with each other and limit the separation of the first shell 1 and the second shell 2, so that the bonding groove 12 and the bonding portion 22 remain engaged, thereby ensuring the sealing performance of the two.

[0037] 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, facilitating the combination and separation of the first shell 1 and the second shell 2.

[0038] like Figure 4 In the illustrated embodiment, the fixing groove 23 protrudes from the side surface of the second housing 2 , so that the fixing groove 23 can be easily operated using tools, etc., to help the fixing portion 13 to be disengaged, thereby reducing the difficulty of disassembly and assembly.

[0039] 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.

[0040] like Figure 6In the embodiment shown, 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 interlocking with each other, and the interlocking position is filled with a combining medium 3 to seal the combining groove 12. The fixing groove 23 and the fixing portion 13 are suitable for being connected to each other and restricting the combining portion 22 from being separated from the combining groove 12. The combining medium 3 can fill the gap that may be present when the combining groove 12 and the combining portion 22 are interlocked, thereby further improving the tightness and sealing of the combining groove 12 and the combining portion 22.

[0041] 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.

[0042] 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.

[0043] In some embodiments, the photovoltaic connector protective cover also includes a barrier 4. Before the first shell 1 and the second shell 2 are combined, the barrier 4 is used to isolate the first combining side 16 and the second combining side 25 to ensure that the first shell 1 and the second shell 2 are not accidentally combined before installation, which facilitates handling and transportation.

[0044] In some embodiments, the barrier 4 is preferably made of non-stick paper to prevent the binding medium 3 from being transferred 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.

[0045] In some embodiments, an elastic rope may be wrapped around the outside of the first shell 1 and the second shell 2 to bundle them, so that the first shell 1 and the second shell 2 can stably clamp and fix the barrier 4 .

[0046] like Figure 7 In the embodiment shown, the fixing portion 13 is arranged 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, reducing the probability of the barrier 4 detaching and falling, and improving stability during transportation.

[0047] 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.

[0048] like Figure 6 In the illustrated embodiment, when the coupling portion 22 is engaged with the coupling groove 12, overflow gaps 5 are 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 generation of cavities and the resulting reduction in sealing.

[0049] In some embodiments, the first protrusion 221 can be a sealing strip, which is embedded in the top of the joint 22. Since the sealing strip has a certain elastic deformation ability, when the joint groove 12 and the joint 22 are engaged, the sealing strip can contact the joint 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 joint groove 12 and the joint 22, and the sealing strip can help promote the flow of the joint medium 3.

[0050] In some embodiments, the sealing strip is made of rubber.

[0051] like Figure 1 In the illustrated embodiment, a first wire groove 14 is provided on the first bonding side 16 of the first shell 1, and a second wire groove 24 is provided on the second bonding side 25 of 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.

[0052] like Figure 3 and 4 In the embodiment shown, 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.

[0053] In some embodiments, the coupling slot 12 passes through the first wire slot 14 or the second wire slot 24 .

[0054] like Figure 3 and 4 In the embodiment shown, the combining groove 12 passes through the first wire groove 14, and the combining portion 22 is connected to 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, 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, thereby realizing the surrounding overall sealing of the cavity, avoiding the occurrence of glue breakage between the combining groove 12 and the first wire groove 14, resulting in insufficient sealing.

[0055] like Figure 4 In the illustrated embodiment, at least one second protrusion 15 is circumferentially provided in the first wire groove 14 and / or the second wire groove 24 .

[0056] 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 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.

[0057] 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. The number of the second protrusions 15 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.

[0058] The joint 22 is the edge portion formed by the first shell 1 on the side of the first accommodating groove 11 or the edge portion formed by the second shell 2 on the side of the second accommodating groove 21, that is, the joint 22 is a partial structure of the first shell 1, and the joint 22 and the first shell 1 form a whole, so that the joint 22 can obtain higher structural strength, reduce the probability of aging and deformation of the joint 22, and improve stability in long-term use.

[0059] 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 to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application.
