[0002] In the field of electronic equipment, connectors, as crucial connection components between circuit systems, have always had their performance and cost as key considerations in design and manufacturing. Existing connectors generally consist of an insulating body, a grounding plate clipped onto the outside of the insulating body, and a metal shell covering the outside of the insulating body. The connector achieves grounding through the interaction of the grounding plate and the metal shell, ensuring stable circuit connection and electromagnetic compatibility. However, this structure of metal shell and grounding plate not only increases material costs but also requires complex processing techniques during manufacturing, further driving up the overall manufacturing cost. Utility Model Content
[0003] To address the shortcomings of the existing technology, the technical problem this invention aims to solve is to provide a grounding ring that enables the connector to achieve grounding, thereby replacing the method of grounding by combining a grounding plate with a metal shell. In this case, the connector shell can be made of a non-metallic material, achieving the dual goals of cost reduction and performance maintenance.
[0004] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a grounding ring is provided for grounding a connector, including a ring body and a connector provided on the ring body for connecting a grounding wire, and the ring body is further provided with a locking component for engaging with the insulator of the connector.
[0005] Furthermore, the connector extends from one end of the ring towards the other end away from the ring.

[0008] Furthermore, the engaging assembly includes at least two fastening members disposed on at least two opposite sides of the ring body, the fastening members being used to engage with the fastening groove of the insulator when the ring body is assembled with the insulator.
[0009] Furthermore, each of the fastening elements is disposed on the inner side of the ring body, and a receiving cavity is formed between the fastening element and the inner side. The receiving cavity is used to accommodate the outer groove wall of the fastening groove when the fastening element is fastened to the fastening groove.
[0010] Furthermore, the fastening member includes a fastening portion located on the inner side of the ring body and spaced apart from it, and a connecting portion for connecting the fastening portion and the ring body.

Detailed Implementation
[0022] The present invention will be further described below with reference to the accompanying drawings.
[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram shows a structural schematic of an embodiment of the grounding ring of this utility model. Figure 2 This is a schematic diagram of the structure of the grounding ring, including the ring body, connecting parts, and fastening parts, in one embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of the grounding ring, including the ring body, connecting parts, and fastening parts, in one embodiment of the present invention. Figure 4 This is a partial cross-sectional view of an embodiment of the grounding ring of this utility model. In this text, in conjunction with... Figures 1 to 4 The grounding ring shown is illustrated by way of example to more clearly demonstrate the various components and their mating relationships. It should be understood that although the following will use... Figures 1 to 4 The grounding ring shown is described in detail as an example, but it is not intended to limit the scope of the grounding ring of this utility model. Apart from the components that solve the necessary technical problems of this utility model, the other components can be regarded as non-essential technical elements. These non-essential technical elements can be replaced by other technical elements with the same or similar functions or structures in other embodiments, or these non-essential technical elements may not be needed in other embodiments.
[0024] Please see Figure 1 In the embodiment shown, the grounding ring is made of metal and is used to surround the insulator 6 of the connector to ground the connector (not shown). The grounding ring includes a ring body 1 and a connector 2 (not shown) disposed on the ring body 1 for connecting a grounding wire.
[0025] The shape of the ring 1 must be adapted to the shape of the insulator 6. For example, when the insulator 6 has a cylindrical structure, the ring 1 is configured as a circular ring structure adapted to the cylindrical structure. For example, when the insulator 6 has a rectangular structure, the ring 1 is configured as a frame structure adapted to the rectangular structure. In this embodiment, the ring 1 is described as an example of a frame structure. The frame-shaped ring 1 is formed by connecting multiple side walls end to end. For example, the ring 1 is formed by connecting four side walls end to end to enclose a rectangular frame structure. The length of each side wall distributed along the insertion direction is adapted to the length of the insulator 6 in the corresponding direction, so as to form a better grounding effect when assembled on the outer periphery of the insulator 6.
[0026] Considering the mating requirements between the ring body 1 and the insulator 6 of the connector, the ring body 1 is further provided with a locking assembly 3 for engaging with the insulator 6 of the connector. The design of the locking assembly 3 allows the ring body 1 to be tightly coupled to the insulator 6 without the need for additional fasteners or adhesives, simplifying the assembly process and improving the overall reliability and durability of the connector. This also enables the ring body 1 to be detachably connected to the insulator 6 of the connector via the locking assembly 3.
[0027] Please refer to Figure 2 and Figure 3 The ring 1 is inserted into the insulator 6 along the insertion direction. In order to facilitate a detailed description of the structure of the grounding ring, we define the side of the ring 1 further away from the insulator 6 in the insertion direction as the first end face 11, and the side closer to the insulator 6 as the second end face 12. That is, the first end face 11 and the second end face 12 are two opposite ends.
[0028] The connector 2 is disposed on the second end face 12 of the ring body 1. The design of the connector 2 allows for high flexibility in its integration with the ring body 1, adapting to different application scenarios and manufacturing requirements through various connection methods. Specifically, the connector 2 can be connected to the ring body 1 using any existing connection method, including but not limited to threaded connections, snap-fit connections, welding, bonding, or mechanical locking. For example, in the illustrated embodiment, the connector 2 is integrally formed extending from the second end face 12 of the ring body 1 towards the other end away from the ring body 1. The connector 2 is elongated, and its lateral sides at the end away from the ring body 1 extend outward in an arc shape. Specifically, the extension direction is away from the ring body 1. The connector 2 and its two arc-shaped extensions together form a semi-enclosed space 21. This semi-enclosed space 21 is used to connect the grounding wire. Simultaneously, this semi-enclosed space 21 can limit the connection between the grounding wire and the connector 2, preventing the connection from slipping off the sides of the connector 2. The ring body 1 is provided with two connectors 2 as described above. Both connectors 2 are located on the second end face 12 of the ring body 1, but on the second end face 12, they are located at the upper and lower sides of the insulator 6 respectively. That is, the two connectors 2 are symmetrically arranged on two opposite sides of the ring body 1. The two connectors 2 arranged in this way can connect two grounding wires, so as to better ground the insulator 6.
[0029] The engaging assembly 3 includes at least two engaging members 31 disposed on at least two opposite sides of the ring body 1, and at least two engaging grooves 32 are formed on the insulator 6 to match the at least two engaging members 31. Each engaging member 31 is disposed on the first end face 11 of the ring body 1 and extends toward the inner side of the ring body 1. Specifically, each engaging member 31 includes an engaging portion 311 and a connecting portion 312. The connecting portion 312 is disposed on the first end face 11, specifically, the connecting portion 312 extends from the first end face 11 toward the center of the ring body 1, and the direction of the connecting portion 312 is perpendicular to the insertion direction. The engaging portion 311 is fixedly disposed at the end of the connecting portion 312 away from the ring body 1, and the engaging portion 311 is perpendicular to the connecting portion 312, that is, the engaging portion 311 extends from the end of the connecting portion 312 toward the interior of the ring body 1 along the insertion direction. The inner surface of the ring 1, the fastening part 311, and the connecting part 312 together form a receiving cavity 35. The receiving cavity 35 is used to accommodate the outer groove wall 36 of the fastening groove 32 when the fastening member 31 is fastened to the fastening groove 32. Please refer to Figure 4The fastening groove 32 is formed along the insertion direction at the position of the insulator 6 corresponding to the fastening member 31. The fastening part 311 is inserted into the fastening groove 32 to achieve fastening. The fastening part 311 has barbs 313 on both sides of its lateral direction, which are used to tightly engage with the inner wall of the fastening groove 32. Two fastening members 31 are symmetrically arranged on two opposite sides of the ring body 1, and two fastening grooves 32 are also correspondingly arranged on two opposite sides of the insulator 6. This symmetrical arrangement of at least two fastening members 31 and two fastening grooves 32 ensures more uniform force distribution between the ring body 1 and the insulator 6, resulting in a more stable engagement.
[0030] The engaging assembly 3 further includes at least two engaging members disposed on at least two opposite sides of the ring body 1, the engaging members being configured as elastic engaging members 33. A through groove 34 for mounting the elastic engaging member 33 is provided on the ring body 1, the through groove 34 penetrating the outer peripheral wall of the ring body 1. The elastic engaging member 33 is mounted within the through groove 34. Specifically, one end of the elastic engaging member 33 near the insulator 6 is fixedly connected to the corresponding side wall of the through groove 34 near the insulator 6, and the other end of the elastic engaging member 33 is a free end, that is, this end is not connected to the through groove 34. The elastic engaging member 33 is inclined, and the free end of the elastic engaging member 33 is inclined towards the center of the ring body 1 to extend into the interior of the ring body 1. In the illustrated embodiment, four elastic engaging members 33 are disposed on two opposite sides of the ring body 1. The multiple elastic engaging members 33, which are symmetrically arranged and spaced apart, can make the engagement between the ring body 1 and the insulator 6 more stable.
[0031] The ring 1 is also provided with a guide member, which provides guidance for the ring 1 when it is engaged with the insulator 6. The guide member can be configured as a guide groove 4 and / or a guide block 5, and the insulator 6 is provided with corresponding guide blocks 5 and / or guide grooves 4 corresponding to the guide members on the ring 1. In the illustrated embodiment, the guide member is a guide groove 4. The guide groove 4 is formed by recessing the second end face 12 of the ring 1 towards the first end face 11 along the insertion direction, and the guide groove 4 is elongated. The guide block 5 is fixedly disposed on the insulator 6 at a position corresponding to the guide groove 4. Specifically, the guide block 5 is also disposed along the insertion direction, and the width of the guide block 5 matches the width of the guide groove 4. When the ring 1 is engaged with the insulator 6, the guide block 5 slides in from one side of the guide groove 4. When the ring 1 is engaged with the insulator 6, the guide block 5 slides completely into the guide groove 4 and fits tightly against the guide groove 4. The guide member described above includes at least two members disposed on at least two opposite sides of the ring 1. In the illustrated embodiment, the guide member described above has four members disposed on two opposite sides of the ring 1. This symmetrical and spaced arrangement of multiple guide members makes the engagement and positioning between the ring 1 and the insulator 6 more accurate, and the engagement between the two is tighter, less prone to shaking or slippage.
[0032] One embodiment of the grounding ring of this utility model operates as follows: the ring body 1 can be snapped onto the insulator 6, or it can be removed from the insulator 6. When we need to snap the grounding ring onto the insulator 6, the snapping process is as follows:
[0033] Holding the insulator 6 in one hand and the grounding ring in the other, adjust them to a suitable position, i.e., so that the opening of the guide groove 4 faces the insulator 6. Move the ring 1 closer to the insulator 6 until it is fitted onto the outer circumference of the insulator 6. As the ring 1 begins to engage with the insulator 6, the end of the fastening part 311 extends into the fastening groove 32. As the ring 1 and the insulator 6 move closer together, the fastening part 311 gradually and completely engages into the fastening groove 32, until finally the inner side of the connecting part 312 contacts the outer wall of the insulator 6. During this process, the guide block 5 also slides into the guide groove 4 from its opening and slides along the length of the guide groove 4 (i.e., the insertion direction) until it reaches the innermost end of the guide groove 4. When the ring 1 is engaged with the insulator 6, the guide block 5 fits tightly against the guide groove 4. Simultaneously, the elastic engaging member 33 also moves as the ring 1 and the insulator 6 approach each other. The free end of the elastic engaging member 33 is pushed up by the outer peripheral wall of the insulator 6 and moves towards the outside of the ring 1. At this time, since the elastic engaging member 33 itself has a tendency to reset its free end towards the inside of the ring 1, the free end of the elastic engaging member 33 will tightly abut against the outer peripheral wall of the insulator 6 under its own elastic force, which plays the role of fixing the ring 1 and the insulator 6, making the engagement between the ring 1 and the insulator 6 tighter and more stable.
[0034] After the ring 1 and the insulator 6 are properly connected, the grounding wire can be connected to the ring 1 to ground the insulator 6. Specifically, the grounding wire is connected to the connector 2, so that the connection point between the grounding wire and the connector 2 is located within the semi-enclosed space.
[0035] When we need to replace, repair or clean the grounding ring, we can separate the ring body 1 from the insulator 6. The separation method is to pull the ring body 1 off the insulator 6 along the insertion direction. The fit of each component during separation is the opposite of the fit during the above-mentioned snap-fit process, so it will not be described in detail here.
[0036] Compared with the prior art, the grounding ring of this utility model achieves the grounding of the connector through a metal grounding ring. In this case, the connector shell can be made of non-metallic materials such as plastic. Compared with the traditional method of combining grounding plates with metal shells, this combination results in lower manufacturing costs while maintaining the stability of circuit connection and shielding effect. It is an economical and efficient connector grounding solution.
