Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a high-voltage connector shielding ring. Background Technology

[0002] High-voltage connectors are widely used in power transmission, electric vehicles, industrial equipment and other fields. Their internal shielding ring is a key component for electromagnetic shielding and electrical connection in high-voltage electrical systems. The shielding ring of high-voltage connectors is usually made of metal (such as copper, aluminum or plated metal) and designed as a ring or cylindrical structure to tightly wrap high-voltage wire harnesses or connectors. When the high-voltage system is running, it will generate a strong electromagnetic field. The shielding ring absorbs or reflects electromagnetic waves to prevent them from interfering with the surrounding electronic equipment.

[0003] The existing high-voltage connector shielding rings mostly adopt a sleeve-fit design, that is, the shielding ring is clamped and fixed to the connector shell or conductor by a clamping plate bent at the end. This method requires manual bending of the clamping plate for clamping and fixing, and the reverse bending is required for disassembly, which can easily lead to fatigue and breakage of the clamping plate, reduce the reusability of the shielding ring, and have low operation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a high-voltage connector shielding ring to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-voltage connector shielding ring, comprising:

[0007] The shielding ring body has several clamping plates fixedly connected to each other symmetrically on its inner wall;

[0008] The connector body has a shielding ring body fitted inside it. The connector body has several grooves inside that correspond to the card plate. Each of the two opposite inner walls of the grooves is provided with an elastic buckle.

[0009] The disassembly assembly includes a top plate, and two pressing blocks are fixedly connected to the bottom surface of the top plate at positions corresponding to several grooves.

[0010] Furthermore, each of the aforementioned cards has a connector hole on its top surface.

[0011] Furthermore, the bottom surface of each of the aforementioned grooves is fixedly connected with a plug-in post that mates with the plug-in hole.

[0012] Furthermore, each of the aforementioned plug-in pins has a positioning groove on its top surface.

[0013] Furthermore, the bottom surface of the top plate is fixedly connected to a number of positioning slots, and a docking block is fixedly fitted onto each of the positioning rods near the outer wall of the top plate.

[0014] Furthermore, the shielding ring body has fixing grooves on its two opposite outer side walls.

[0015] Furthermore, the top plate has mounting grooves on its two opposite sidewalls, and each mounting groove is rotatably connected to a clamping plate by a torsion spring. The inner sidewalls of the two clamping plates are fixedly connected to a fixing block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By fixing several clamping plates to the inner wall of the shielding ring body, and opening grooves corresponding to the clamping plates inside the connector body, and setting two elastic buckles inside the grooves for fixing the clamping plates, the installation of the shielding ring body is made easier, eliminating the need to bend the clamping plates, reducing the difficulty of operation and the risk of damage.

[0018] The shielding ring body is quickly released by aligning and inserting the compression blocks into the grooves on the bottom surface of the top plate with the corresponding positions of each elastic buckle, thus preventing damage to the shielding ring body during disassembly. This improves the reusability of the shielding ring body and reduces maintenance costs. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] Please see Figure 1-5 In this embodiment of the present invention, a high-voltage connector shielding ring includes a shielding ring body 100, a connector body 200, and a disassembly assembly 300. A plurality of retaining plates 110 are symmetrically fixedly connected to the inner wall of the shielding ring body 100. The number of retaining plates 110 is 4 to 6, evenly distributed on the inner wall of the shielding ring body 100. The shielding ring body 100 is fitted inside the connector body 200. A plurality of grooves 210 corresponding to the retaining plates 110 are formed inside the connector body 200. The two opposing inner walls of the grooves 210 are... An elastic buckle 220 is provided, with a certain gap between the bottom surface of the elastic buckle 220 and the bottom surface of the groove 210. The thickness of this gap matches the thickness of the card plate 110. The disassembly assembly 300 includes a top plate 310. Two pressing blocks 320 are fixedly connected to the bottom surface of the top plate 310 and the corresponding positions of several grooves 210. The positions of the two pressing blocks 320 correspond to the positions of the two elastic buckles 220, respectively. The distance between the side wall of the card plate 110 and the side wall of the groove 210 matches the thickness of the pressing block 320.

[0028] Specifically, during installation, the shielding ring body 100 is axially inserted into the connector body 200, aligning the retaining plate 110 with the groove 210. After applying downward pressure, the retaining plate 110 presses against the two elastic clips 220, causing them to retract. When the bottom surface of the retaining plate 110 contacts the bottom surface of the groove 210, the two elastic clips 220 spring back and lock onto the top surface of the retaining plate 110, thus fixing the shielding ring body 100. When it is necessary to disassemble the shielding ring body 100, the top plate 310 is placed on the top surface of the connector body 200, aligning the two elastic clips 220 in each groove 210 with the two pressing blocks 320 at their corresponding positions. The top plate 310 is pressed downward, causing the pressing blocks 320 to move downward and push the two elastic clips 220 to retract, so that the elastic clips 220 no longer clamp the retaining plate 110. At this time, the shielding ring body 100 and the disassembly assembly 300 can be pulled out together.

[0029] like Figure 2 and Figure 4-5As shown, in this embodiment, the top surfaces of several card plates 110 are provided with insertion holes 120, the bottom surfaces of several grooves 210 are fixedly connected with insertion posts 230 that mate with the insertion holes 120, the top surfaces of several insertion posts 230 are provided with positioning grooves 231, the bottom surfaces of the top plate 310 and the positions corresponding to the several positioning grooves 231 are fixedly connected with positioning rods 330, and the several positioning rods 330 are sleeved and fixedly connected with docking blocks 340 near the outer wall of the top plate 310. The bottom surface of the docking block 340 is used to contact the top surface of the insertion post 230, and each positioning rod 330 is respectively arranged between two corresponding extrusion blocks 320.

[0030] In this embodiment, when the shielding ring body 100 is fitted inside the connector body 200, the insertion hole 120 is inserted into the positioning groove 231, achieving dual constraint. When the shielding ring body 100 is disassembled, the positioning rod 330 and the positioning groove 231 enable the disassembly component 300 to be better aligned with the shielding ring body 100 and the connector body 200. When the positioning rod 330 is fully inserted into the positioning groove 231, the pressing block 320 also presses and retracts the elastic buckle 220, facilitating quick disassembly.

[0031] like Figure 2 and Figure 5 As shown, in this embodiment, the two opposite outer sidewalls of the shielding ring body 100 are provided with fixing grooves 130, and the two opposite sidewalls of the top plate 310 are provided with mounting grooves 311. The two mounting grooves 311 are rotatably connected to the clamps 350 by torsion springs, and the inner sidewalls of the two clamps 350 are fixedly connected to the fixing blocks 351.

[0032] In practice, under the action of the torsion spring, the two clamping plates 350 are perpendicular to the top plate 310 by default. When the shielding ring body 100 needs to be disassembled, the top plate 310 is placed vertically down against the top surface of the shielding ring body 100. The two fixing blocks 351 will deflect outward when they contact the outer wall of the shielding ring body 100. When the pressing block 320 is fully inserted into the groove 210, the position of the fixing block 351 corresponds to the position of the fixing groove 130. Under the action of the torsion spring, the two fixing blocks 351 are respectively embedded in the two fixing grooves 130. At this time, the connector body 200 loses its fixation to the shielding ring body 100, and the disassembly component 300 clamps the shielding ring body 100 through the two clamping plates 350. At this time, the disassembly component 300 is lifted directly to bring out the shielding ring body 100 simultaneously. Then, by pinching the upper end of the two clamping plates 350, the shielding ring body 100 can be quickly released.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
