[0034] In the figure, units with similar structures are denoted by the same reference numerals.
[0035] In the terms of this utility model, words such as "first" and "second" are only for descriptive purposes and cannot be construed as indicating or implying relative importance, nor as a limitation on the order of precedence.
[0036] A connector with stable structure provided by this utility model includes an inner shell 15 with an L-shaped structure, a rubber core 16 clamped on the inner shell 15, and a limiting component 11 for positioning the rubber core 16. An annular protrusion 161 and a positioning protrusion 163 located on one side of the annular protrusion 161 are arranged on the circumferential side of the rubber core 16. The limiting component 11 includes an inner sleeve 113 connected to one end of the rubber core 16 and sleeved on the first end of the inner shell 15, and a plug sealing sleeve 112 connected to the inner sleeve 113. A first positioning piece 152 separable from the inner shell 15 and a second positioning piece 151 connected to the inner shell 15 are arranged at the first end of the inner shell 15. Arc-shaped grooves 153 are arranged in both the first positioning piece 152 and the second positioning piece 151. The arc-shaped groove 153 of the first positioning piece 152 is connected to the arc-shaped groove 153 of the second positioning piece 151. The first positioning piece 152 is further provided with a first notch 1521 for clamping the positioning protrusion 163. The first notch 1521 is vertically arranged with respect to the arc-shaped groove 153. The inner shell 15 is used for installing the rubber core 16, and the limiting component 11 is used for fixing the rubber core 16 to prevent the rubber core 16 from rotating or shaking inside the inner shell 15. When fixing the rubber core 16, first, separate the first positioning piece 152 from the inner shell 15, place the rubber core 16 inside the second positioning piece 151, and clamp the annular protrusion 161 of the rubber core 16 in the arc-shaped groove 153 of the second positioning piece 151. Then, place the first positioning piece 152 on the other side of the rubber core 16, so that the annular protrusion 161 of the rubber core 16 is also connected in the arc-shaped groove 153 of the first positioning piece 152. At the same time, the positioning protrusion 163 of the rubber core 16 is clamped in the first notch 1521 of the first positioning piece 152, and the first notch 1521 positions the rubber core 16 to prevent the rubber core 16 from rotating inside the housing. Further, insert the inner sleeve 113 from the direction of the first positioning piece 152 and the second positioning piece 151 into the circumferential side of the inner shell 15. The inner sleeve 113 fixes and limits the first positioning piece 152 and the second positioning piece 151. When the inner sleeve 113 is connected to the circumferential side of the inner shell 15, the inner sleeve 113 fixes the first positioning piece 152 and the second positioning piece 151 to prevent the first positioning piece 152 from separating from the inner shell 15. Through the above structure, the rubber core 16 can be stably fixed and positioned, effectively preventing the rubber core 16 from rotating and shaking inside the inner shell 15, thereby effectively ensuring the connection between the rubber core 16 and the signal wire.
[0037] The rubber core 16 is further provided with a positioning groove 162 located inside the annular protrusion 161. The positioning groove 162 and the positioning protrusion 163 are on the same vertical line. The inner wall of the inner sleeve 113 is provided with a fixing block 1131 that extends into the first notch 1521 and is clamped in the positioning groove 162. The fixing block 1131 of the inner sleeve 113 is clamped in the positioning groove 162, further fixing the rubber core 16 and further preventing the rubber core 16 from rotating inside the inner shell 15. At the same time, the positioning groove 162 and the positioning protrusion 163 are on the same vertical line. At the same time, the positioning groove 162 is located inside the first notch 1521, eliminating the need to open a slot on the first positioning piece 152 and avoiding further processing of the first positioning piece 152.
[0038] The second positioning piece 151 and the inner shell 15 are integrally formed. The integrally formed inner shell 15 and the second positioning piece 151 have stronger hardness, effectively preventing the second positioning piece 151 from separating from the inner shell 15.
[0039] One side of the inner sleeve 113 is further provided with a second notch 1133 that is clamped with the inner shell 15. The second notch 1133 is used to facilitate the clamping of the inner sleeve 113 at the second end of the inner shell 15. On the one hand, it is used to reduce the length of the inner sleeve 113. On the other hand, it is used to prevent the inner sleeve 113 from rotating when connected to the inner shell 15.
[0040] Please refer to Figure 10 , Figure 10 As shown in, which is a three-dimensional view of the elastic lock sleeve of the connector with stable structure of the present utility model. The limiting component 11 is further provided with an elastic lock sleeve 111 clamped on the inner sleeve 113. The elastic lock sleeve 111 is located inside the plug sealing sleeve 112. One end of the elastic lock sleeve 111 away from the inner sleeve 113 is provided with two or more fixing protrusions 1111. The connector is further provided with a sleeve 12 sleeved on the peripheral side of the inner sleeve 113. The position of the sleeve 12 opposite to the fixing protrusions 1111 is provided with fixing holes for clamping the fixing protrusions 1111. The elastic lock sleeve 111 is connected to the inner sleeve 113 and fixed by the plug sealing sleeve 112. The sleeve 12 extends from the direction of the elastic lock sleeve 111. When the fixing protrusions 1111 are clamped in the fixing holes, the sleeve 12 is fixed on the elastic lock sleeve 111. Due to the elastic action of the elastic lock sleeve 111, when the sleeve 12 presses the fixing protrusions 1111, the fixing protrusions 1111 are deformed. When the sleeve 12 passes through the fixing protrusions 1111 and is clamped in the fixing holes, the fixing protrusions 1111 recover their deformation and are stably clamped in the fixing holes.
[0041] In this embodiment, symmetric clamping grooves 1132 are further provided on the outer wall of the inner sleeve 113. Clamping protrusions 1112 extending into the clamping grooves 1132 are provided at positions of the elastic lock sleeve 111 opposite to the clamping grooves 1132. On the one hand, they are used to position the elastic lock sleeve 111, facilitating the positioning of the fixing holes of the sleeve 12 and the fixing protrusions 1111. On the other hand, they are used to prevent the elastic lock sleeve 111 from rotating on the inner sleeve 113.
[0042] The connector is further provided with a rear cover 13. One end of the rear cover 13 extends into the sleeve 12 and is threadedly connected to the inner sleeve 113, for preventing water from entering the inner shell 15.
[0043] A third notch is provided on one side of the sleeve 12. The third notch is clamped to the second end of the inner shell 15, for preventing the sleeve 12 from rotating. A plurality of anti-slip grooves are provided on the circumferential side of the sleeve 12. The anti-slip grooves are used to prevent slipping with the hand when installing the sleeve 12. At the same time, they are used to increase the aesthetic feeling of the sleeve 12.
[0044] An elastic wire clip sleeve 17 connected to the second end of the inner shell 15 and a tail cap 14 for fastening the elastic wire clip sleeve 17 are provided at the second end of the inner shell 15. A sealing ring 18 is further provided at the second end of the inner shell 15. The sealing ring 18 abuts against the elastic wire clip sleeve 17. The elastic wire clip 17 is used to clamp a signal wire. The tail cap 14 is used to fasten the elastic wire clip 17, preventing the signal wire from loosening in the elastic wire clip 17.
[0045] Working principle:
[0046] When assembling the connector, first, separate the first positioning piece 152 from the second positioning piece 151, place the rubber core 16 on the second positioning piece 151, and the annular protrusion 161 of the rubber core 16 is snap-fitted into the arc-shaped groove 153 of the second positioning piece 151. Then, close the first positioning piece 152 and the second positioning piece 151. At this time, the annular protrusion 161 of the rubber core 16 is snap-fitted into the arc-shaped grooves 153 of the first positioning piece 152 and the second positioning piece 151. The arc-shaped grooves 153 of the first positioning piece 152 and the second positioning piece 151 limit the rubber core 16 to prevent the rubber core 16 from separating from the first positioning piece 152 and the second positioning piece 151. At the same time, the positioning protrusion 163 of the rubber core 16 is snap-fitted into the first notch 1521 of the first positioning piece 152, and the first notch 1521 limits the rubber core 16 to prevent the rubber core 16 from rotating within the first positioning piece 152 and the second positioning piece 151. Further, insert the inner sleeve 113 into the first end of the inner shell 15 from the direction of the first positioning piece 152 and the second positioning piece 151. The inner sleeve 113 is connected to the peripheral side of the inner shell 15. At the same time, the inner sleeve 113 fixes the first positioning piece 152 and the second positioning piece 151. The fixing block 1131 of the inner sleeve 113 extends into the first notch 1521 and is snap-fitted into the positioning groove 162. On the one hand, it further fixes the rubber core 16. On the other hand, it is used to limit the first positioning piece 152 to prevent the first positioning piece 152 from shaking within the inner sleeve 113. When the inner sleeve 113 is connected to the peripheral side of the inner shell 15, the second notch 1133 of the inner sleeve 113 is snap-fitted into the second end of the inner shell 15 to prevent the inner sleeve 113 from rotating on the housing.
[0047] Further, connect the elastic lock sleeve 111 to one end of the inner sleeve 113, and insert the plug sealing sleeve 112 into the inner side of the elastic lock sleeve 111 and fix it on the inner shell 15. The plug sealing sleeve 112 fixes the elastic lock sleeve 111 to prevent the elastic lock sleeve 111 from separating from the inner sleeve 113. Further, insert the sleeve 12 from the direction of the plug sealing sleeve 112 and sleeved on the peripheral side of the inner sleeve 113. The third notch of the sleeve 12 is snap-fitted into the second end of the inner shell 15 to prevent the sleeve 12 from rotating on the inner sleeve 113. At the same time, during the insertion process of the sleeve 12, it squeezes the fixing protrusion 1111, and the fixing protrusion 1111 deforms. When the fixing protrusion 1111 is aligned with the fixing hole, the fixing protrusion 1111 resumes deformation and is snap-fitted into the fixing hole, thereby preventing the sleeve 12 from separating from the inner sleeve 113. Finally, install the elastic wire clip 17 and the end cap 14 at the second of the inner shell 15. Through the above structure, the first positioning piece 152 and the second positioning piece 151 limit and fix the rubber core 16, and the inner sleeve 113 further fixes the rubber core 16, enabling the rubber core 16 to be stably connected within the connector, effectively avoiding the problems of the rubber core 16 rotating within the connector and the signal wire breaking, and making the connection between the connector and the rubber core 16 more stable.
[0048] The connector with stable structure in this preferred embodiment fixes the rubber core between the first positioning piece and the second positioning piece. The annular protrusion of the rubber core is clamped in the arc-shaped groove. At the same time, the positioning protrusion of the rubber core is clamped in the first notch. The first positioning and the second positioning limit the rubber core, and the first notch positions the rubber core. The inner sleeve fixes the first positioning piece and the second positioning piece, and stably fixes the rubber core in the inner shell. After the signal wire is connected to the rubber core, the connection between the rubber core and the signal wire can be effectively guaranteed.
[0049] In summary, although the present utility model has been disclosed above with the preferred embodiments, the above preferred embodiments are not intended to limit the present utility model. Those of ordinary skill in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope defined by the claims.
