Description

Technical Field

[0001] This utility model relates to the field of electronic connector technology, and in particular to a waterproof RJ45 high-speed socket connector suitable for photovoltaic energy storage systems. Background Technology

[0002] RJ45 is a type of connector used in cabling systems for information outlets (i.e., communication leads). The connector consists of a plug (connector, crystal head) and a socket (module). A photovoltaic energy storage system, also known as a solar photovoltaic energy storage power generation system, is a power generation system composed of photovoltaic equipment and energy storage equipment.

[0003] In photovoltaic energy storage systems, RJ45 connectors must meet stringent requirements such as high reliability, waterproofing, vibration resistance, and corrosion resistance. Existing RJ45 connectors generally suffer from the following defects:

[0004] Insufficient grounding reliability: Traditional grounding structures are mostly single-point contacts, making it difficult to achieve synchronous and reliable grounding of multiple network ports, which can easily lead to signal interference or lightning protection failure.

[0005] Poor structural stability: The fixing of the plastic shell and the shielding shell relies on glue or interference fit, which is prone to loosening after long-term use, resulting in poor contact. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a high-speed socket connector. This invention adopts a grounding spring with a symmetrical bending structure, which has strong anti-signal interference ability, high grounding reliability, and strong structural stability.

[0007] The technical solution adopted by this utility model is as follows: A high-speed socket connector includes a metal shell, an RJ45 plastic shell, an RJ45 ferrule, and a grounding spring. The metal shell is wrapped around the RJ45 plastic shell. A mesh opening is provided at each end of the RJ45 plastic shell. The RJ45 ferrule includes a PCB board and two contact terminals electrically connected to both ends of the PCB board. The RJ45 ferrule is disposed inside the RJ45 plastic shell, and the two contact terminals extend into the two mesh openings respectively. A slot is also provided on the RJ45 plastic shell. The grounding spring includes a fixing part, an overlapping part, and two spring parts. The fixing part is inserted into the slot, and the two spring parts extend into the two mesh openings respectively. A fastening point is provided on the metal shell. The overlapping part and the fastening point are fastened together. The RJ45 plastic shell is fixed inside the metal shell through the overlapping part.

[0008] The RJ45 plastic shell has two slots symmetrically distributed along its axis. Each of the two slots contains a grounding spring, and the two grounding springs are also symmetrically installed along the axis of the RJ45 plastic shell. The metal shell also has two fastening points symmetrically arranged along its axis for the two grounding springs to overlap and engage.

[0009] The fastening point is located on the outer wall of one end of the metal casing, and a baffle for blocking the RJ45 plastic shell is provided on the end of the metal casing away from the fastening point.

[0010] The RJ45 plastic housing includes a first housing and a second housing. The first housing and the second housing have the same structure and are symmetrically spliced ​​together. An installation cavity for fixing the RJ45 insert is formed between the first housing and the second housing. Both the first housing and the second housing are provided with at least one protrusion and at least one circular groove.

[0011] It also includes an outer shell with a rubber coating. The outer wall of the metal shell has a recessed annular groove, and the outer shell is wrapped around the outside of the annular groove by a secondary injection molding process.

[0012] The metal outer shell is also provided with at least one axially extending protruding edge at the position corresponding to the annular groove, and the inner wall of the outer shell is recessed with at least one groove that matches the protruding edge.

[0013] The metal casing is also covered with at least two sealing gaskets, and the two sealing gaskets respectively abut against the two sides of the casing's rubber coating.

After assembly, both network ports can be connected to the shielded crystal head through the spring parts, providing grounding connection for both network ports. The grounding of multiple network ports is synchronized, with strong anti-signal interference capability and high grounding reliability. Furthermore, the overlapping part on the grounding spring engages with the snap fastener of the metal shell to fix the RJ45 plastic shell to the metal shell, resulting in strong structural stability. The integrated design of network port grounding, spring, and metal shell is conductive. The insertion and engagement of the fixing part with the slot, as well as the engagement of the overlapping part with the snap fastener, form a three-dimensional fixing structure of "RJ45 plastic shell - grounding spring - metal shell", ensuring the axial and radial stability of the component.

[0027] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0028] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0030] like Figures 1 to 9 The diagram illustrates an embodiment of this utility model: a high-speed socket connector, comprising a metal housing 1, an RJ45 plastic housing 2, an RJ45 ferrule 3, and a grounding spring 4. The metal housing 1 encloses the RJ45 plastic housing 2. Each end of the RJ45 plastic housing 2 has a mesh opening 5. The RJ45 ferrule 3 includes a PCB board 6 and two contact terminals 7 electrically connected to both ends of the PCB board 6. The RJ45 ferrule 3 is disposed inside the RJ45 plastic housing 2, and the two contact terminals 7 extend into the two mesh openings 5. The RJ45 plastic housing 2 also has a slot 8. The grounding spring 4 includes a fixing part 9, an overlapping part 10, and two spring parts 11. The fixing part 9 is inserted into the slot 8, and the two spring parts 11 extend into the two mesh openings 5. The metal housing 1 has a fastening point 12, and the overlapping part 10 engages with the fastening point 12. The RJ45 plastic housing 2 is fixed inside the metal housing 1 by the overlapping part 10.

[0031] The beneficial effects of this design are as follows: This utility model adopts a symmetrically bent grounding spring with two spring parts on each grounding spring. After assembly, both network ports can be connected to the shielded crystal head through the spring parts, providing grounding connection for both network ports simultaneously. This enables synchronous grounding of multiple network ports, strong anti-signal interference capability, and high grounding reliability. Furthermore, the overlapping part on the grounding spring engages with the snap fastener of the metal shell to fix the RJ45 plastic shell to the metal shell, resulting in strong structural stability. The integrated design ensures that the network port grounding, spring, and metal shell are all conductive. The insertion and engagement of the fixing part with the slot, as well as the engagement of the overlapping part with the snap fastener, form a three-dimensional fixing structure of "RJ45 plastic shell - grounding spring - metal shell," ensuring the axial and radial stability of the component. The RJ45 connector integrates two network port contact terminals for transmitting high-speed signals. The overlapping part is a bent shape extending from one end of the fixing part to the outside of the metal shell. When the overlapping part engages with the snap fastener on the outer wall of the metal shell, the RJ45 plastic shell is fixed to the metal shell. The contact spring integrates grounding and fixing functions, reducing the number of independent components and eliminating the need for soldering to the circuit board. The overall size is smaller than traditional solutions, making it more cost-effective. It is suitable for high-speed data connections between inverters, battery management systems (BMS) and other equipment in photovoltaic energy storage systems, and is especially suitable for humid and high-vibration environments such as outdoor cabinets and distributed energy storage nodes.

[0032] Further, the RJ45 plastic shell 2 has two slots 8 symmetrically distributed along the axis, and each of the two slots 8 has a grounding spring 4. The two grounding springs 4 are also symmetrically installed along the axis of the RJ45 plastic shell 2. The metal shell 1 also has two fastening points 12 symmetrically arranged along the axis for the two grounding springs 4 to overlap and cooperate.

[0033] The benefits of this setup are as follows: each network port can be provided with two grounding contact points through two grounding springs, resulting in more stable connections due to multiple contact points. The metal casing also has two fastening points for the two overlapping parts to fasten together, making the connection between the RJ45 plastic shell and the metal shell more secure.

[0034] Further, the fastening point 12 is located on the outer wall of one end of the metal casing 1, and a baffle 13 for blocking the RJ45 plastic casing 2 is provided on the end of the metal casing 1 away from the fastening point 12.

[0035] The beneficial effects of this design are as follows: one end of the metal casing is connected to the overlapping part of two grounding springs through two fastening points, and the other end also has a baffle to block and limit the RJ45 plastic casing, further fixing the RJ45 plastic casing. Compared with the traditional fixing method that relies on glue or interference fit, this structure has stronger stability.

[0036] Further, the RJ45 plastic shell 2 includes a first shell 14 and a second shell 15. The first shell 14 and the second shell 15 have the same structure and are symmetrically spliced. An installation cavity 16 for fixing the RJ45 insert 3 is formed between the first shell 14 and the second shell 15. The first shell 14 and the second shell 15 are each provided with at least one protrusion 17 and at least one circular groove 18.

[0037] The advantages of this design are as follows: the RJ45 housing adopts a split structure, which is assembled from two housings. The two housings have the same structure, which makes processing convenient and reduces production costs. During installation, they are installed symmetrically, resulting in high assembly efficiency. The installation of the RJ45 ferrule and grounding spring is also more convenient. The RJ45 ferrule is pre-embedded in the installation cavity, and the grounding spring is inserted into the slots of the two housings in sequence. The two housings are assembled and fixed by the insertion and mating of the protrusion and the groove.

[0038] Further, it also includes an outer shell coating 19, wherein the outer wall of the metal outer shell 1 has a recessed annular groove 20, and the outer shell coating 19 is wrapped around the outside of the annular groove 20 by a secondary injection molding process.

[0039] The beneficial effects of this design are as follows: the diameter of the annular groove is smaller than that of the metal casing, resulting in a larger contact area; the casing is less prone to slippage due to the rubber coating; the casing is coated using a secondary injection molding process to wrap the metal casing, forming a coating layer that covers the seams and extends to the wiring harness interface, achieving full coverage to prevent corrosion of the metal casing; it has excellent waterproof performance and strong corrosion resistance; the casing is coated with UV-resistant nylon material, which is resistant to corrosion and aging, making it more suitable for coastal or high-humidity photovoltaic power stations; it is also less prone to rust in high-humidity, salt spray, and other environments, resulting in a longer service life.

[0040] Furthermore, the metal outer shell 1 is provided with at least one axially extending protruding edge 21 at the position corresponding to the annular groove 20, and the inner wall of the outer shell coating 19 is recessed with at least one groove 22 that matches the protruding edge 21.

[0041] The beneficial effects of this design are as follows: the convex edge and the groove cooperate to prevent the outer shell from rotating relative to the metal shell, further preventing the outer shell from falling off and making it more secure.

[0042] Furthermore, the metal casing 1 is also covered with at least two sealing gaskets 23, and the two sealing gaskets 23 respectively abut against both sides of the casing rubber coating 19.

[0043] The beneficial effects of this design are as follows: it also adds a sealing gasket and a rubber-coated outer shell to create a three-dimensional waterproof system that can withstand 1m of water depth for 30 minutes without leakage (IP67 test), meeting the IP67 protection level and long-term outdoor corrosion resistance requirements.

[0044] Further, a metal nut 24 is included, and the outer walls at both ends of the metal housing 1 are provided with external threads 25. The metal nut 24 is threadedly connected to the metal housing 1 through the external threads 25.

[0045] The beneficial effects of this design are as follows: the high-speed socket connector can be fixed to the panel 26 by means of a metal nut, ensuring a secure installation.

[0046] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
