DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] Please refer to the attached Figure 1-Figure 9 The present invention proposes a connector with an anti-misinsertion structure, which includes a shielding shell 1, a plastic body 2, a light-emitting element 5, an insulating sheet 6, a bottom plate 4 and a plurality of terminals 3. The plastic body 2 is snap-fitted and fixed in the shielding shell 1; the terminals 3 are snap-fitted and fixed to the bottom of the plastic body 2 in a linear arrangement; the terminals 3 include a first terminal 31, a second terminal 32 and a third terminal 33, and the first terminal 31 and the second terminal 32 are respectively arranged on the left and right sides of the third terminal 33; the first terminal 31 and the second terminal 32 are respectively provided with a stopper 34, the stopper 34 is in a sheet shape and is arranged on the horizontal plane between the first terminal 31 and the second terminal 32 and the bottom of the plastic body 2, and the first terminal 31 and the second terminal 32 are respectively integrally formed with the stopper 34. The insulating sheet 6 fixes the light-emitting element 5 on the left and right sides of the plastic body 2 respectively; the bottom plate 4 is arranged at the bottom of the plastic body 2, and the bottom plate 4 is fixedly connected to the shielding shell 1 for fixing the plastic body 2. The bottom plate 4 is disposed at the bottom of the plastic body 2 and is provided with a bottom plate through hole 42 . The shielding shell 1 is provided with a fixing plate 7 . The fixing plate 7 passes through the bottom plate through hole 42 and is fixedly connected to an external device and is used to fix the plastic body 2 .

[0031] In this embodiment, the plastic body 2 is snap-fitted and fixed in the shielding shell 1, and the bottom of the plastic body 2 is embedded in the bottom plate groove 41. Among them, a plurality of terminals 3 are snap-fitted in the lower terminal groove 21 of the plastic body 2 in a linear arrangement, and the soldering feet of the terminal 3 and the light-emitting element 5 respectively pass through the second through hole 422, which can prevent the soldering feet of the terminal 3 and the light-emitting element 5 from being deformed and displaced. A stopper 34 is provided on the terminal 3, and the terminal 3 includes a first terminal 31, a second terminal 32 and a third terminal 33. The stopper 34 is respectively arranged on the first terminal 31 and the second terminal 32, and the stopper 34 is respectively integrally formed with the first terminal 31 and the second terminal 32. The stopper 34 can effectively prevent the insertion of a non-standard crystal head and electrical connection with the connector, causing damage to the connector. When the non-standard crystal plug is inserted, one end of the terminal 3 located in the plastic body 2 is squeezed by the plastic parts on both sides of the non-standard crystal plug, and elastic deformation occurs and squeezes downward. At this time, under the action of the limiter, the non-standard crystal plug is pressed against the plug interface of the connector and cannot be directly inserted into the connector to achieve electrical connection. The limiter 34 on the terminal 3 can prevent the deformation of the terminal 3 from exceeding the elastic limit and causing plastic deformation, thereby reducing the cost of the terminal 3 and the subsequent maintenance cost. The lower terminal groove 21 includes a first terminal groove 211, a second terminal groove 212 and a third terminal groove 213. The front ends of the first terminal groove 211 and the second terminal groove 212 are respectively provided with bosses 22, which can prevent the insertion of the non-standard crystal plug from damaging the terminal 3 of the connector and also reduce the development cost of the mold. The plastic body 2 is also provided with a light-emitting element 5, and the insulating sheet 6 fixes the light-emitting element 5 in the light-emitting element grooves 23 on the left and right sides of the plastic body 2, respectively. The insulating sheet 6 is mainly used for electrical insulation and protection of the connector; the state of the light-emitting element 5 can intuitively reflect whether the plugged into the connector is a standard crystal head, which can prevent the misinsertion of non-standard crystals. The light-emitting element grooves 23 on the plastic body 2 are also provided with fixing parts 25 and protruding structures 26. The protruding structures 26 in the light-emitting element grooves 23 are deformed by the extrusion of the solder pins of the light-emitting element 5, and then the light-emitting element 5 is clamped and fixed in the light-emitting element grooves 23; the fixing parts 25 are heated to melt and collapse into the light-emitting element grooves 23 to further fix the light-emitting element 5. The first buckle 24 on the plastic body 2 and the second buckle 12 on the shielding shell 1 are respectively clamped with the first clamping hole 13 and the second clamping hole 14 on the shielding shell 1, so that the connection between the plastic body 2 and the shielding shell 1 is more stable.

[0032] When the standard crystal head is plugged into the connector, the shell of the standard crystal head will not be interfered by the limit piece 34, and the boss 22 set at the front end of the first terminal groove 211 and the second terminal groove 212 will not limit the plugging of the standard crystal head. The boss 22 can prevent the standard crystal head from colliding and rubbing against the terminal 3 at the first bend 81 when plugging and unplugging, so that the contact terminal on the standard crystal head can be normally electrically connected with the terminal on the connector.

[0033] Please refer to Figure 6 A lower terminal groove 21 is provided at the bottom of the plastic body 2, and the lower terminal groove 21 includes a first terminal groove 211, a second terminal groove 212 and a third terminal groove 213. A boss 22 is also provided on the inner side of the bottom of the plastic body 2, and the boss 22 is symmetrically arranged at the front end of the first terminal groove 211 and the second terminal groove 212.

[0034] In the specific implementation: a lower terminal groove 21 is provided at the bottom of the plastic body 2, the terminal 3 includes a first terminal 31, a second terminal 32 and a third terminal 33, the lower terminal groove 21 includes a first terminal groove 211, a second terminal groove 212 and a third terminal groove 213, the terminals 3 are linearly arranged and snapped into the lower terminal groove 21, and the first terminal 31 and the second terminal 32 are respectively provided with a limiter 34, the limiter 34 can prevent the misinsertion of non-standard crystal heads; the front ends of the first terminal groove 211 and the second terminal groove 212 are respectively provided with a boss 22, and one end of the boss 22 is provided with a slope facing the outside of the plug-in interface of the plastic body 2, which can prevent the plastic parts on both sides of the non-standard crystal head from being inserted to damage the terminal 3 of the connector, and also reduce the development cost of the mold.

[0036] In the specific implementation: the bending part 8 includes a first bending part 81, a second bending part 82, a third bending part 83 and a fourth bending part 84, and the third bending part 83 and the fourth bending part 84 are arranged in the upper terminal groove 27; the lower terminal groove 21 includes a first terminal groove 211, a second terminal groove 212 and a third terminal groove 213, the first bending part 81 is arranged at the front end of the lower terminal groove 21, and the front ends of the first terminal groove 211 and the second terminal groove 212 are respectively provided with bosses, and the height of the first bending part 81 is less than the height of the boss 22, so as to prevent the insertion of a non-standard crystal head from damaging the terminal 3 at the first bending part 81 and shortening the service life of the terminal 3, and the bending size of the terminal 3 can also be adjusted according to the requirements of the correct positioning.

[0037] Please refer to Figure 7-Figure 8 The width of the first terminal 31 and the second terminal 32 disposed in the lower terminal groove 21 is greater than the width of the third terminal 33 disposed in the lower terminal groove 21 .

[0038] In specific implementation: the first terminal 31, the second terminal 32 and the third terminal 33 are arranged in the lower terminal groove 21, and the first terminal 31 and the second terminal 32 are also provided with a stopper 34, wherein the stopper 34 of the first terminal 31 and the stopper 34 of the second terminal 32 are both integrally formed. The width of the first terminal 31 and the second terminal 32 arranged in the lower terminal groove 21 is greater than the width of the third terminal 33 arranged in the lower terminal groove 21, which is more convenient for the arrangement of the stopper 34. If the width of the first terminal 31 and the second terminal 32 is small, the height of the stopper 34 is not enough, and the restriction on the non-standard crystal head cannot be achieved, which is easy to damage the terminal 3 of the connector.

[0039] Please refer to Figure 1 and Figure 4 The bottom plate through hole 42 includes a first through hole 421 and a second through hole 422. The first through hole 421 is respectively arranged on the left and right sides of the bottom plate 4, and the second through hole 422 is arranged at the lower end of the first through hole 421. The fixing plate 7 passes through the first through hole 421 and is fixedly connected to the external device. The second through hole 422 is used to fix the terminal 3.

[0040] In specific implementation: the bottom plate through hole 42 includes a first through hole 421 and a second through hole 422. The fixing plate 7 of the shielding shell 1 passes through the first through hole 421 to be fixedly connected to an external device, and the external device includes but is not limited to a network device and a telephone line, thereby fixing the plastic body 2 so that the plastic body 2 does not easily shift. The second through hole 422 is provided at the lower end of the first through hole 421. The soldering feet of the terminal 3 and the light-emitting element 5 pass through the second through hole 422 to be electrically connected to the external device, which can prevent the soldering feet of the terminal 3 from being deformed and shifted, and interfering with other terminals 3.

The soldering feet of the terminal 3 and the light-emitting element 5 on the plastic body 2 pass through the second through hole 422 along the assembly direction, so that the soldering feet of the terminal 3 and the soldering feet of the light-emitting element 5 do not affect each other during operation, thereby preventing the soldering feet of the terminal 3 and the light-emitting element 5 from being deformed and displaced.

[0043] Please refer to Figure 5-Figure 6 A light emitting element groove 23 is provided above the plastic body 2 , and the light emitting element groove 23 is used for placing the light emitting element 5 .

The fixing part 25 is arranged at the end of the light-emitting element groove 23 and is located between the soldering feet of the light-emitting element 5. The protruding structure 26 is symmetrically arranged on the inner side of the light-emitting element groove 23 for fixing the soldering feet of the light-emitting element 5.

[0046] In the specific implementation, the protruding structure 26 on the inner side of the light emitting element groove 23 is deformed by the solder pins of the light emitting element 5, thereby clamping and fixing the light emitting element 5 in the light emitting element groove 23; the light emitting element groove 23 is also provided with fixing parts 25, which are arranged at the end of the light emitting element groove and between the solder pins of the light emitting element, and the fixing parts 25 and the light emitting element 5 are fixed by hot-melt welding.
