DETAILED DESCRIPTION

[0038] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations on the technical solution of the present invention. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0039] The term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " generally indicates an "or" relationship between the related objects. Example 1

[0040] like Figures 1-14 The figure shows a multi-thread wall-through connector, comprising: an outer shell 1, an insulator 2, a sealing ring 3, and a pin 4 (pin 4 is a conductor). Pin 4 passes through insulator 2, and outer shell 1 is sleeved over insulator 2. Sealing ring 3 is sleeved around insulator 2 and embedded between insulator 2 and outer shell 1. Specifically, sealing ring 3 is made of silicone. The interference fit between the silicone sealing ring 3 and the outer shell 1 ensures IP67-level waterproofing.

[0041] Specifically, the pin 4 has a tip 44 and a tail 35 at either end. The pin 4 is also provided with one or more of a boss 41, a barbed cone 42, and a barbed ring 43, which engage with the interior of the insulator 2. In this embodiment, the pin 4 is provided with bosses 41, barbed cones 42, and barbed rings 43 in sequence from the tip 44 to the tail 35. The boss 41 is a ring, with the smaller cross-sectional diameters of the barbed cones 42 and barbed rings 43 facing the tail 45, and the larger cross-sectional diameters of the barbed cones 42 and barbed rings 43 facing the tip 44. The tip of the pin 4 extends through the insulator 2. The barbed cones 42 and barbed rings 43 are embedded and confined within the insulator 2 in a barbed configuration. Furthermore, the needle tail 45 of the pin 4 is inserted into the insulator 2 from one end of the insulator 2 where the inner ring groove is provided; the barbed cone 42 and the barbed ring 43 are embedded in the insulator 2, and the boss 41 of the pin 4 is embedded in the inner ring groove of the insulator 2.

[0042] Specifically, the outer shell 1 is a hollow shell with inwardly protruding barbs 13 on its inner wall. The two ends of the outer shell 1 are a butt end 11 and a tail end 12, respectively. The insulator 2, with the pin 4 inserted therethrough, is inserted into the outer shell 1, with the barbs 13 pressed against the exterior of the insulator 2. After the insulator 2 is inserted into the outer shell 1, a butt cavity 111 is reserved in the butt end 11. The terminal end of the tip 44 of the pin 4 retracts into the butt cavity 111 within the outer shell 1. Furthermore, the barb cone 42 and the barb ring 43 have the same retraction direction; the barb 13 has a retraction direction opposite to that of the barb cone 42 and the barb ring 43. Example 2

[0043] Based on the first embodiment, Figures 1-16 As shown, a limiting ring platform 114 is provided on the outside of the outer shell 1, and the limiting ring platform 114 is located between the butt end 11 and the tail end 12; a ring groove 116 is provided on the side where the limiting ring platform 114 is connected to the butt end 11; and a ring groove 116 is provided on the side where the limiting ring platform 114 is connected to the tail end 12. Example 3

[0044] On the basis of Example 1 or Example 2, Figures 1-16 As shown, a limiting tooth groove is provided on the boss 41 , the barbed cone 42 , or the barbed ring 43 of the pin 4 , and the slotting track of the limiting tooth groove is parallel to the central axis of the pin 4 . Example 4

[0045] On the basis of Example 1, Example 2 or Example 3, Figures 1-16 As shown, an external thread 113 is provided on the outside of the butt end 11 of the outer shell 1; an external thread 2 121 is provided on the outside of the tail end 12 of the outer shell 1; and an internal thread 112 is provided in the butt cavity 111 of the outer shell 1. Example 5

[0046] On the basis of Example 1 or Example 2 or Example 3 or Example 4, Figures 1-16 As shown, the outer shell 1 adopts SUS303 plus passivation process, and the strength can reach more than 500N without deformation. The sealing ring 3 is made of silicone material and is only 0.6mm in size, but can achieve IP67 waterproof level. This connector is easy to assemble and saves labor time.

[0047] Working principle:

[0048] The utility model discloses a multi-thread wall-penetrating connector. Its flexible thread connection facilitates multi-directional and multifunctional connections, easily adapting to a wide torque assembly range and exhibiting excellent waterproofing. The main body of the outer shell 1 is designed with three threads: two external threads (external thread 113 and external thread 2 121) and one internal thread (internal thread 112). The inner conductor, a pin 4, is provided with parallel steps (a boss 41, a barbed cone 42, and a barbed ring 43) to increase the torque between the pin 4 and the insulator 2. A silicone sealing ring 3 is added to the connection between the outer shell 1 and the insulator 2. This ring fits inside the outer shell 1, providing a waterproof seal.

[0049] This utility model discloses a multi-thread wall-penetrating connector. Its three connecting threads (internal thread 112, external thread 113, and external thread 21) facilitate connection with a wide range of mating components. The central pin 4 is equipped with a boss 41, a barbed cone 42, and a barbed ring 43. After assembly, the connector can withstand torques up to 2 Nm, a significant advantage in the industry. A silicone sealing ring 3 creates an interference fit with the outer shell 1, achieving IP67-rated waterproofing. The connector is versatile and multi-purpose. For disassembly and maintenance, simply loosen the three connecting threads (internal thread 112, external thread 113, and external thread 21), providing a convenient threaded connection interface.

[0050] Based on the ideal embodiment of the present invention, and through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the content of the specification, but must be determined according to the scope of the claims.
