electrical connector

This invention relates to an electrical connector.

Known technology reference China Mainland Utility Model Patent CN216289323U discloses a shielded electrical connector with a light-emitting display, including an intermediate insulator made of electrically insulating material, and a shielding element in the rear connection area, wherein the shielding element is in a ring shape. The intermediate insulator surrounds and forms part of the electromagnetically effective shielding layer, and wherein the intermediate insulator electrically insulates the rear connection section of the contact element and the conductor front end from the shield element. However, in this electrical connector, the middle insulator is formed first and then the shielding element is cast on the outside, which is complex in process and high in cost.

Therefore, it is necessary to provide an improved electrical connector to solve the above problems.

The purpose of this invention is to provide an electrical connector having a mask ring provided with glue holes.

In order to achieve the above purpose, this creation can adopt the following technical solutions:

An electrical connector includes an insulating body, a plurality of conductive terminals fixed on the insulating body, and a metal threaded member sleeved on the front end of the insulating body. The electrical connector includes a shield ring sleeved on the insulating body. , the front end of the shield ring and the rear end of the threaded member overlap each other, the shield ring extends backward and exceeds the rear end surface of the insulating body and is provided with a plurality of through-holes for glue filling.

Compared with the conventional technology, this invention uses glue holes to make it easier to fill the inside of the mask ring to form a whole when covering the mask ring during subsequent plastic injection molding.

In order to facilitate a better understanding of the purpose, structure, characteristics and functions of the present invention, the present invention is further described with reference to the accompanying drawings and specific implementation methods.

Referring to FIGS. 1 to 7 , an electrical connector 100 of the present invention includes an insulating body 1 , a plurality of conductive terminals 2 fixed on the insulating body 1 , and a metal thread 3 sleeved on the front end of the insulating body 1 . The electrical connector 100 also includes a shield ring 4 that is sleeved on the insulative body 1. The front end of the shield ring 4 and the rear end of the threaded member 3 overlap each other. The shield ring 4 extends rearward and exceeds the rear end surface of the insulative body 1. A plurality of through glue filling holes 41 are provided. With this arrangement, the plastic filling holes 41 make it easier to fill the inside of the mask ring 4 and form it into one body during subsequent plastic injection molding.

The insulating body 1 includes a base portion 11 and a plug portion 12 extending forward from the base portion 11 . The base 11 is provided with an outwardly protruding step portion 13 at the connection point with the insertion portion 12 , and the mask ring 4 abuts forward against the rear end surface of the step portion 13 . The rear end surface of the step portion 13 is wavy, see Figure 6 .

The mask ring 4 is provided with an outwardly projecting skirt 42 at its front edge. The rear edge of the threaded member 3 is provided with an annular boss 31 protruding inward, and the skirt 42 is clamped between the step portion 13 and the boss 31 in the front-rear direction. The electrical connector 100 includes a covering member 5 formed integrally with the mask ring 4 by injection molding. The covering member 5 fills the inside of the mask ring 4 through the glue holes 41 . The number of the glue filling holes 41 is four, and they are arranged opposite each other. The mask ring 4 extends rearward and exceeds the rear end surface of the base 11 . The glue filling hole 41 is located behind the rear end surface of the base 11 . The shield ring 4 includes a guide area 43 and an installation area 44 located behind the guide area 43. The diameter of the guide area 43 is larger than the installation area 44. The guide area 43 guides the insulating body 1 to be received in the installation area 44. See Figure 5. At the same time, the guide area 43 can also be used as a space to accommodate plastic debris generated during the installation process of the insulating body 1 .

The electrical connector 100 includes a rubber ring 6 that is sleeved on the plug portion 12 and rearwardly resists the front end surface of the step portion 13 . The threaded member 3 surrounds the plug portion 12 to form a docking cavity 32, and the inner surface of the docking cavity 32 has a thread structure. The number of conductive terminals 2 is 8. The plug portion 12 extends rearward from its front end to form a fool-proof groove 121 . The insulating body 1 is provided with a terminal slot 14 for receiving the conductive terminal 2. The terminal slot 14 runs through the insulating body in the front and rear direction. Insulated body 1, the conductive terminal 2 includes a contact portion 21 located at the front end of the terminal slot 14, a holding portion 22 held by the insulating body 1, and a pin 23 extending rearward and extending from the insulating body. The pin 23 extends rearward but does not exceed the cover. Ring 4 trailing edge.

The electrical connector 100 includes a cable 7 connected to the rear end of the conductive terminal 2 . The cable 7 includes a wire core 71 and a shielding layer 72 . The threaded member 3, the mask ring 4 and the mask layer 72 are electrically connected. In this embodiment, because the exposed part of the wire core is long, if the mask layer 72 covers this part of the exposed wire core 71, it will easily lead to the inability to re-cover the wire core during injection molding. Therefore, the mask layer 72 is twisted into a grounding thread. The wire 721 is welded to the end of the mask ring 4. The ground wire 721 is simply illustrated in FIG. 7 .

To sum up, this creation meets the requirements for a new type of patent, and a patent application can be filed in accordance with the law.
