[0035] One embodiment of this utility model provides a waterproof puncture-resistant connector, see reference. Figure 1 This includes a front connector 1 and a rear connector 2 that are plugged into each other;

[0036] refer to Figure 3 The front-end connector 1 includes:

[0037] Front shell 11;

[0038] A plurality of connecting terminals 12 are installed in a ring shape inside the front housing 11. A slot 121 is formed at the first end of any of the connecting terminals 12 along its length direction. A piercing part 122 for piercing the cable is provided at the opening of the slot 121.

[0039] refer to Figure 4 and Figure 5 The back-end connector 2 includes:

[0040] The rear outer casing 21 is connected to the front outer casing 11 by a thread;

[0041] The sealing ring 22 abuts against the front connector 1 and the rear connector 2;

[0042] The first network cable 23 has a plurality of wire ends at its first end that are inserted into the slots 121 of the connection terminal 12, and the wire ends are arranged in an L-shape.

[0043] In this embodiment, the structure of existing connectors is improved. Traditional connectors typically employ a multi-component stacked structure to achieve waterproof performance, such as multi-layer waterproof sleeves and multi-layer shell structures. This results in a generally large radial dimension of the connector head, which cannot meet the requirements of compact structural design and occupies a large space. In this embodiment, a sealing ring 22 is set between the front and rear connector heads. The sealing ring 22 directly abuts against the front and rear connector heads, eliminating the need to set multiple sealing rings 22 at the core, wire outlet, etc. The structure is simple while ensuring waterproof performance. The front and rear shells 21 are connected by threads, which can form a uniform and stable compression on the sealing ring 22 when tightened. The structure is easy to disassemble and assemble, while further ensuring waterproof performance and avoiding the defects of insufficient sealing pressure and easy loosening of traditional snap-fit ​​connections.

[0044] Several connecting terminals 12 are installed in a ring inside the front housing 11. The terminal layout is realized by utilizing the circumferential space of the front housing 11, eliminating the traditional linear arrangement structure. With the same number of terminals, the overall radial space is greatly reduced. At the same time, the wire end of the first network cable 23 is set in an L-shaped structure, which can be inserted into the slot 121 of the connecting terminal 12 along the circumference of the front and rear housings 21, without the need for additional wiring space, thus reducing the radial size of the connector.

[0045] The front and rear housings 21 are connected only by threads, without the need to disassemble other parts. When separating, simply unscrew the threads manually, and when connecting, tighten the threads to complete the assembly. The operation is simple and the structure is stable. The slot 121 of the connecting terminal 12 has a piercing part 122 at the opening. When wiring, there is no need to strip the cable insulation layer. Simply align the cable with the piercing part 122 and insert it. The piercing part 122 can penetrate the insulation layer and contact the wire core, which is convenient to use.

[0046] Furthermore, the front connector 1 also includes a front plastic body 13, and a plurality of the connecting terminals 12 are inserted and fixed to the front plastic body 13.

[0047] In this embodiment, the front plastic body 13 can be provided with corresponding insertion holes according to the number and position of the connecting terminals 12. The connecting terminals 12 can be inserted into the insertion holes respectively. The connecting terminals 12 and the insertion holes can be interference fit to ensure the installation stability of the connecting terminals 12. At the same time, the front plastic body 13 can effectively wrap the connecting terminals 12 to prevent them from deforming, and at the same time, provide insulation protection to improve the safety performance of use.

[0048] Furthermore, the front plastic body 13 is configured as a one-piece molded structure made of PC material. It should be noted that PC material has good mechanical properties, high strength and rigidity, which can greatly improve the support for the connecting terminal 12, prevent deformation, and ensure the positioning accuracy of the connecting terminal 12.

[0049] Furthermore, the second ends of several of the connection terminals 12 are connected to a second network cable 14, the second network cable 14 extends to the outside of the front housing 11, and the connection between the second network cable 14 and the front housing 11 is wrapped with an outer mold 15.

[0050] In this embodiment, the outer mold 15 can be made of a sealing material, such as silicone or TPU in the prior art. After molding, it tightly wraps around the outer wall of the second network cable 14 and the through hole of the front shell 11, filling the gap and forming a sealed and waterproof structure, further improving the waterproof performance of the connector. Furthermore, the outer mold 15 wrapping around the outer wall of the front shell 11 and the second network cable 14 can improve the stability of the second network cable 14 and prevent it from falling off or being damaged after long-term use.

[0051] Furthermore, the connection between the second network cable 14 and the connecting terminal 12 is coated with silicone sealant 16. In this embodiment, the silicone sealant 16, after curing, has a certain elasticity, which can generate a continuous elastic pre-tightening force on the contact surface between the connecting terminal 12 and the second network cable 14, ensuring the stability of the connection. At the same time, it can isolate the exposed metal part of the connection from the external environment, preventing oxidation and corrosion when moisture enters, thus improving waterproof performance and safety performance.

[0052] Furthermore, the rear connector 2 also includes a rear plastic body 24, which wraps around the outside of the first network cable 23. It should be noted that, since the first network cable 23 contains multiple cores, the wire ends are prone to tangling or friction with the inner wall of the rear outer casing 21, damaging the outer insulation layer of the cable and affecting its service life. Therefore, in this embodiment, by setting the rear plastic body 24, the cores of the second network cable 14 are fixed as a whole, effectively protecting them and preventing water from entering the cable, further improving its waterproof performance.

[0053] Furthermore, the sealing ring 22 is installed on the outer side of the rear plastic body 24. It should be noted that in this embodiment, the rear plastic body 24 has an annular positioning groove integrally formed on its outer side. The sealing ring 22 can be precisely embedded in the positioning groove to ensure positioning accuracy. During assembly, the sealing ring 22 can be installed in the positioning groove first, and then the plastic body 24 can be assembled integrally, simplifying the assembly process and improving assembly efficiency. At the same time, the threaded connection between the front and rear shells provides clamping force, which tightly fits the sealing ring 22 against the outer shell, improving waterproof performance.

[0054] Furthermore, the rear connector 2 also includes a shielding spring 25, which is installed on the outside of the plastic body and has an abutment portion that abuts against the inside of the front housing 11. In this embodiment, the shielding spring 25 is made of a metal material with excellent conductivity, such as phosphor bronze or stainless steel, and is installed on the outside of the rear plastic body 24 to form a closed shielding cavity with the front housing 11, completely enclosing the mating area of ​​the first network cable 23, the L-shaped cable end, and the front connector terminal 12, thereby achieving full shielding of the signal transmission area.

[0055] Furthermore, the rear connector 2 also includes a silicone sealing body 26, which is installed inside the rear plastic body 24 and wraps around the outside of the first network cable 23. It should be noted that the first network cable 23, as the rear input cable, is easily subjected to tensile forces from dragging during actual use. Long-term stress can easily lead to problems such as cracking of the cable insulation layer and breakage of the core. Silicone has good elastic recovery properties; therefore, in this embodiment, the silicone sealing body 26 is used to wrap around the outside of the first network cable 23, which can absorb most of the external force and improve the protection of the first network cable 23. At the same time, the silicone sealing body 26 can fill structural gaps and improve waterproof performance.

[0056] Furthermore, the front outer shell 11 and the rear outer shell 21 are both configured as a one-piece stainless steel structure. In this embodiment, by using a stainless steel outer shell, the corrosion resistance and structural stability of the outer shell can be improved. At the same time, the one-piece structure has no seams, which can further improve the waterproof performance.

[0057] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
