Description

Technical Field

[0001] This application relates to the field of connector structure technology, and in particular to an RJ45 crystal head outer mold structure. Background Technology

[0002] An RJ45 (Registered Jack 45) is a standardized 8-pin, 8-contact (8P8C) network connector used to terminate network cables and connect network devices. RJ45 connectors connect to RJ45 slots, enabling data transmission between network devices such as computers, routers, and switches.

[0003] Existing RJ45 connectors, lacking a sealing ring or similar structure, typically cannot provide waterproofing. However, in some outdoor or special scenarios, waterproof RJ45 connectors are necessary. Examples include surveillance cameras in public places like city roads and parks, and network devices in damp areas of the home such as bathrooms and kitchens (e.g., smart mirrors, water heater controllers), which require waterproof RJ45 connectors to ensure stable signal transmission. Utility Model Content

[0004] The main purpose of this application is to propose an outer mold structure for RJ45 crystal heads, which aims to solve the problem that existing RJ45 crystal heads do not have waterproof function.

[0005] To achieve the above objectives, the RJ45 crystal head outer mold structure proposed in this application includes: a housing, which is wrapped around the outside of the connection between the crystal head and the cable, a sealing ring is provided on the outside of the housing near the crystal head, and an elastic buckle structure is provided on the housing between the sealing ring and the cable, the elastic buckle structure being used to ensure a stable connection between the crystal head and the socket.

[0006] Optionally, the sealing ring includes an annular body and two annular protrusions. The body is connected to the housing, and the protrusions are perpendicular to the body and face outward. The protrusions and the body are integrally formed, and an annular sealing groove is formed between the two protrusions.

[0007] Optionally, the edges on the protrusion and the connection between the protrusion and the main body are both designed with rounded transitions.

[0008] Optionally, the sealing ring is a structure made of rubber or PU material.

[0009] Optionally, an annular mounting groove is formed on the housing corresponding to the sealing ring, and the width of the mounting groove is the same as the width of the sealing ring.

[0010] Optionally, a receiving groove is formed on the housing between the sealing ring and the cable, and the elastic snap-fit ​​structure is located in the receiving groove.

[0011] Optionally, the elastic buckle structure includes an L-shaped elastic element, the short arm of which is vertically fixedly installed on the inner bottom surface of the receiving groove, and a triangular locking block is provided on the long arm of the elastic element, with the inclined surface of the locking block facing the side of the crystal head.

[0012] Optionally, a circular pressing piece is fixedly connected to the long arm of the elastic element.

[0013] Optionally, the housing has a rectangular structure.

[0014] Optionally, an annular chamfer is provided on the housing between the sealing ring and the crystal head.

[0015] This application's technical solution involves setting up a housing that surrounds the connection between the RJ45 connector and the cable. A sealing ring is positioned on the outer side of the housing near the RJ45 connector, and an elastic snap-fit ​​structure is located on the housing between the sealing ring and the cable. This elastic snap-fit ​​structure ensures a stable connection between the RJ45 connector and the socket. During installation, the RJ45 connector is inserted into the socket, and the sealing ring on the outer side of the housing contacts the inner wall of the socket port, forming a seal. The elastic snap-fit ​​structure embeds into the socket's slot, mechanically securing the RJ45 connector and preventing loosening during insertion and removal. By placing the elastic snap-fit ​​structure on the side closer to the cable, a sealing ring can be installed on the housing. This sealing ring prevents external impurities (water, dust, etc.) from entering, protecting the internal electrical connection. The elastic snap-fit ​​prevents the RJ45 connector from falling off due to vibration or external force, improving interface reliability. This design makes this structure suitable for scenarios requiring waterproofing, improving the signal transmission stability and reliability of the interface. Attached Figure Description

[0028] Existing RJ45 connectors typically lack a sealing ring or similar structure, thus failing to provide waterproofing. However, in some outdoor or special scenarios, waterproof RJ45 connectors are necessary. Examples include surveillance cameras in public places such as city roads and parks, and network devices in damp areas of the home such as bathrooms and kitchens (e.g., smart mirrors, water heater controllers), which require waterproof RJ45 connectors to ensure stable signal transmission.

[0029] In view of this, this application proposes an RJ45 crystal head outer mold structure.

[0030] In the embodiments of this application, reference is made to Figures 1 to 3 The aforementioned RJ45 crystal head outer mold structure includes: a housing 1, which wraps around the connection between the crystal head 4 and the cable 5. A sealing ring 2 is provided on the outer side of the housing 1 near the crystal head 4. An elastic snap-fit ​​structure 3 is provided on the housing 1 between the sealing ring 2 and the cable 5. The elastic snap-fit ​​structure 3 is used to ensure a stable connection between the crystal head 4 and the socket. The sealing ring 2 prevents liquids and dust from entering the connection between the crystal head 4 and the cable 5 through physical contact. The elastic snap-fit ​​utilizes the restoring force generated by the elastic deformation of the material to engage with the socket slot, achieving mechanical locking.

[0031] In this embodiment, the sealing ring 2 includes an annular body 201 and two annular protrusions 202. The body 201 is connected to the housing 1. The protrusions 202 are perpendicular to the body 201 and face outward. The protrusions 202 and the body 201 are integrally formed. An annular sealing groove 203 is formed between the two protrusions 202. The double protrusions 202 design forms two sealing lines. The sealing groove 203 fills the gap through deformation, increases the contact area, and improves the sealing performance. The structure of the protrusions 202 and the sealing groove 203 has stronger sealing performance than a single annular sealing ring 2 and can cope with slight tolerances or vibrations.

[0032] In this embodiment, the edges on the protrusion 202 and the connection between the protrusion 202 and the main body 201 are all designed with rounded transitions; during installation or disassembly, the rounded transitions reduce the frictional resistance between the sealing ring 2 and the socket; the rounded transitions eliminate stress concentration at right-angle connections, reduce the possibility of the sealing ring 2 cracking due to repeated deformation, and improve the durability of the sealing ring 2.

[0033] In this embodiment, the sealing ring 2 is a structure made of rubber or PU material; the sealing ring 2 made of rubber or PU material has good elasticity and sealing effect, and has stable chemical properties, can adapt to humid and complex environments, is wear-resistant and anti-aging, and is suitable for long-term use.

[0034] In this embodiment, an annular mounting groove 101 is formed on the housing 1 corresponding to the sealing ring 2. The width of the mounting groove 101 is the same as the width of the sealing ring 2. After the sealing ring 2 is embedded in the mounting groove 101, the mounting groove 101 fixes the position of the sealing ring 2 by physical limiting, ensuring that it maintains the correct posture during insertion and removal. The groove width matches the width of the sealing ring 2 to prevent the sealing ring 2 from shifting or falling off, avoid the sealing ring 2 from shifting and causing sealing failure, improve assembly accuracy, and the embedded design reduces external protrusions and maintains the overall aesthetics of the housing 1.

[0035] In this embodiment, a receiving groove 102 is provided on the housing 1 between the sealing ring 2 and the cable 5, and the elastic locking block 302 structure is located in the receiving groove 102. The receiving groove 102 can protect the elastic locking structure 3, avoid damage caused by direct impact from external forces, reduce the space occupied by the elastic locking block 302 structure, and make the overall structure of the housing 1 more reasonable and aesthetically pleasing.

[0036] In this embodiment, the elastic locking block 302 structure includes an L-shaped elastic element 301. The short arm of the elastic element 301 is vertically fixedly installed on the inner bottom surface of the receiving groove 102. A triangular locking block 302 is provided on the long arm of the elastic element 301, with the inclined surface of the locking block 302 facing the side of the crystal head 4. When inserted, the inclined surface of the locking block 302 contacts the edge of the socket slot. After being pressed, the elastic element 301 bends, and the long arm drives the locking block 302 to retract. When fully inserted, the locking block 302 springs into the insertion slot and locks the connection. The inclined surface of the triangular locking block 302 allows for forward insertion, while the flat surface prevents reverse pull-out, forming a one-way engagement. The restoring force after the elastic element 301 deforms ensures that the locking block 302 fits tightly against the slot. The inclined surface design achieves "plug and lock" to improve installation efficiency. The one-way engagement requires active pressing to disassemble, avoiding accidental dislodgement.

[0037] In this embodiment, a circular pressing piece 303 is fixedly connected to the long arm of the elastic member 301. When disassembling, the finger presses the circular piece, causing the long arm to deform downward, so that the locking block 302 is disengaged from the socket slot and the lock is released. The pressing piece 303 expands the force-bearing area, reduces the pressure of the finger, increases the length of the long arm of the elastic member 301, reduces the required pressing force, and improves the comfort of operation.

[0038] In this embodiment, the housing 1 has a rectangular structure; the rectangular housing 1 has a simple and regular structure, is easy to manufacture, and provides a regular grip surface, which is convenient for pinching or inserting / removing with fingers.

[0039] In this embodiment, an annular chamfer is provided on the housing 1 between the sealing ring 2 and the crystal head 4. The chamfer guides the crystal head 4 to be inserted in the correct direction through its geometric shape, reducing the difficulty of insertion and removal. When inserted into the socket, the chamfer guides the crystal head 4 to be aligned with the socket entrance, reducing edge collision resistance. The chamfer reduces the initial contact resistance, which is especially suitable for blind insertion scenarios.

[0040] This application's technical solution involves setting up a housing that surrounds the connection between the RJ45 connector and the cable. A sealing ring is positioned on the outer side of the housing near the RJ45 connector. An elastic snap-fit ​​structure is located on the housing between the sealing ring and the cable, ensuring a stable connection between the RJ45 connector and the socket. During installation, the RJ45 connector is inserted into the socket. The sealing ring on the outer side of the housing contacts the inner wall of the socket port, forming a seal. The elastic snap-fit ​​structure embeds into the socket's slot, mechanically securing the RJ45 connector and preventing loosening during insertion and removal. By placing the elastic snap-fit ​​structure on the side near the cable, a sealing ring can be installed on the housing. This sealing ring prevents external impurities (water, dust, etc.) from entering, protecting the internal electrical connection. The elastic snap-fit ​​also prevents the RJ45 connector from falling off due to vibration or external force, improving interface reliability.

[0041] This technical solution achieves a comprehensive improvement in the RJ45 crystal head's waterproof and dustproof properties, connection stability, ease of operation, and durability through a multi-seal structure of the sealing ring, mechanical locking of the elastic buckle, and user-friendly details (such as rounded transitions, pressing tabs, and beveled edges). It is suitable for network connection scenarios with high requirements for environmental sealing and reliability (such as industrial and outdoor equipment).

[0042] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
