Description

Technical Field

[0001] This utility model relates to the field of shielding ring technology, and in particular to a sealing shielding crimping ring for a female connector. Background Technology

[0002] The sealing and shielding crimp ring of the female connector is a key component used in electronic and electrical connectors. Its main functions are to achieve sealing, shielding, and reliable electrical connection. It is commonly used in industrial, aerospace, automotive, and other fields that require high reliability. The sealing, shielding, and crimping functions of the female connector's sealing and shielding crimping ring are typically achieved by different functional parts made of different materials. The sealing function of the shielding crimping ring is usually achieved by a sealing component made of flexible rubber or polymer materials. After crimping, it forms a tight seal, covering the conductor bundle to provide dustproof, waterproof, and oil-proof properties, preventing environmental factors from penetrating the connector and protecting the contact points from contamination or corrosion. The shielding function is usually achieved by a shielding component made of a highly conductive metal (such as copper alloy, silver-plated, or nickel-plated materials). This provides good conductivity while effectively shielding against electromagnetic interference (EMI) or radio frequency interference (RFI), ensuring the stability and reliability of signal transmission. The crimping function is usually achieved by a deformable component with good mechanical strength. Precise pressure is applied to the crimping ring using specialized crimping tools, ensuring stable contact between the crimping ring and the conductor bundle without loosening, thus achieving a secure connection between the cable and the connector, providing reliable mechanical fixation and electrical connection.

[0003] Existing shielding crimping rings are usually designed as cylindrical or claw structures. However, these types of shielding crimping rings are prone to gaps after being deformed by the crimping tool, making it difficult to guarantee sealing performance. This not only affects the protective function of the connector but also its shielding performance. Utility Model Content

[0004] Therefore, it is necessary to provide a sealing shielding crimping ring for the female end connector to address the technical problem of insufficient sealing performance after the existing shielding ring is crimped.

[0005] A sealing and shielding crimping ring for a female connector includes a shielding ring, which includes a sleeve portion and a crimping portion. The sleeve portion is disposed at one end of the shielding ring, and the crimping portion is disposed at the other end of the shielding ring opposite the sleeve portion, thereby forming an integral shielding ring. The sleeve portion is used to mate with a terminal block for connection, and the crimping portion is used to fit onto the outer surface of a wire harness.

[0006] The crimping part includes several grippers, which are connected to the end of the shielding ring. Each gripper extends a predetermined distance in the direction away from the crimping part, thereby forming several clamping mechanisms with a certain clamping area. A clearance groove with a predetermined distance is provided between adjacent grippers.

[0007] A flexible part of a preset area is also provided between adjacent grippers. Several flexible parts correspond one-to-one with several clearance grooves, and the flexible parts are located at the bottom of the corresponding clearance grooves. The two sides of the flexible parts are connected to the adjacent grippers.

[0008] In one embodiment, the shielding ring described above is configured as a centrally symmetrical cylindrical structure.

[0009] In one embodiment, the aforementioned grippers are arranged axially at the end of the shielding ring along a predetermined radius with the center of symmetry of the shielding ring as the axis.

[0010] In one embodiment, a fitting structure is also provided between the two adjacent grippers. The fitting structure is correspondingly provided on the opposing side surfaces of the two adjacent grippers. When the sleeve is closed and compressed, the two adjacent grippers are tightly connected through the corresponding fitting structure.

[0011] In one embodiment, the above-described fitting structure includes a corresponding mating block and a groove. The block is disposed on the corresponding side surface of one of the two adjacent grippers, and the block extends from the end of the gripper to the corresponding flexible portion along the extending direction of the corresponding gripper. The groove is disposed opposite to the block on the corresponding side surface of the adjacent gripper, and similarly, the groove extends from the end of the gripper to the corresponding flexible portion along the extending direction of the corresponding gripper.

[0012] In one embodiment, each of the above-mentioned inserts extends further into the corresponding flexible portion by a predetermined distance, and correspondingly, the adjacent slot extends further into the corresponding flexible portion by a predetermined distance.

[0013] In one embodiment, each of the grippers is further provided with a sealing layer, which is adhered to the outer surface of the gripper.

[0014] In one embodiment, one side of the sealing layer extends outward by a predetermined width toward the corresponding side edge of the gripper to form an overlap.

[0015] In one embodiment, the sealing layer, which is based on the shielding ring as a whole, extends from the end of the gripper to the beginning of the gripper, so that the sealing layer can fully cover the clearance groove in the length direction.

[0016] In one embodiment, the aforementioned socket includes a mating structure disposed on the outer surface of the socket and extending to the end of the socket.

[0017] In one embodiment, the above-described mating structure includes an axial mating block that extends from the outer surface of the sleeve to the end of the sleeve.

[0018] In one embodiment, the above-described mating structure further includes a circumferential mating block, which is disposed on the outer surface of the sleeve portion along the circumference of the sleeve portion.

[0019] The aforementioned female connector sealing and shielding crimping ring connects to the connector head via a sleeve and is fitted onto the outer surface of the wire harness via the crimping part to achieve the limiting and sealing shielding functions of the shielding ring on the wire harness. The crimping part includes several jaws. When the jaws are fitted onto the wire harness, the clearance grooves allow sufficient compression space between adjacent jaws to complete the crimping closure according to the specific dimensions of the wire harness being held, thereby ensuring the clamping stability of the crimping part on the wire harness. A flexible part of a preset area is also provided between adjacent jaws. Several flexible parts correspond one-to-one with several clearance grooves, and the flexible parts are located at the bottom of the corresponding clearance grooves. The two sides of the flexible parts are connected to the adjacent jaws. Thus, when the jaws are compressed, the flexible parts can be squeezed and deformed under the compression of the adjacent jaws and fill the gaps between the jaws, further enhancing the sealing performance of the sleeve and thus strengthening the shielding capability of the shielding ring.

[0028] Please see Figures 1 to 2 This utility model discloses a sealing and shielding crimping ring for a female connector. The sealing and shielding crimping ring includes a shielding ring 10. One end of the shielding ring 10 is fitted and connected to a terminal block with a predetermined number of terminals. The outer surface of the shielding ring 10 is fitted and connected to a suitable connector housing. The other end of the shielding ring 10 is fitted onto the outer surface of a suitable wire harness and sealed to the outer surface of the wire harness by crimping, thereby achieving the shielding function of the shielding ring 10. The shielding ring 10 includes a fitting portion 100 and a crimping portion 200. The fitting portion 100 is disposed at one end of the shielding ring 10, and the crimping portion 200 is disposed at the other end of the shielding ring 10, forming a complete shielding ring 10. The fitting portion 100 is used to fit and connect with the terminal block, and the crimping portion 200 is used to fit onto the outer surface of the wire harness to achieve the limiting and sealing shielding functions of the shielding ring 10 on the wire harness. Specifically, the crimping part 200 includes a plurality of grippers 210, which are connected to the end of the shielding ring 10. Each gripper 210 extends a predetermined distance in the direction away from the sleeve part 100, thereby forming a plurality of clamping mechanisms with a certain clamping area. A clearance groove a of a predetermined distance is provided between adjacent grippers 210. Thus, when the plurality of grippers 210 are sleeved onto the wire harness, the clearance groove a allows the adjacent grippers 210 to have sufficient space for compression and closing to match the specific size of the clamped wire harness, thereby ensuring the clamping stability of the crimping part 200 on the wire harness. More specifically, a flexible portion 220 of a preset area is provided between adjacent grippers 210. Several flexible portions 220 correspond one-to-one with several clearance grooves a, and the flexible portion 220 is located at the bottom of the corresponding clearance groove a. The two sides of the flexible portion 220 are connected to the adjacent grippers 210. Thus, when several grippers 210 are closed and compressed, the flexible portion 220 can be squeezed and deformed under the compression of the adjacent grippers 210 and fill the gap between the grippers 210, so as to further enhance the sealing performance of the sleeve portion 100 and thereby enhance the shielding capability of the shielding ring 10.

[0029] Furthermore, the shielding ring 10 is configured as a centrally symmetrical cylindrical structure. Based on this, several grippers 210 are arranged axially at the ends of the shielding ring 10 with the center of symmetry as the axis of the shielding ring 10 along a preset radius. This makes it easier for the grippers 210 to uniformly clamp the wire bundle, while ensuring the ease of processing of the shielding ring 10 and ensuring a high yield rate.

[0030] Furthermore, a fitting structure is provided between adjacent grippers 210. The fitting structure is correspondingly disposed on the opposing side surfaces of the adjacent grippers 210. When the sleeve portion 100 is closed and compressed, the adjacent grippers 210 are tightly connected through the corresponding fitting structure, thereby ensuring the tightness of the connection between the two grippers 210 and ensuring the sealing performance of the shielding ring 10. Specifically, the fitting structure includes a correspondingly mating insert 211 and a groove b. The insert 211 is disposed on the corresponding side surface of one of the two adjacent grippers 210, and the insert 211 extends from the end of the gripper 210 to the corresponding flexible portion 220 along the extending direction of the corresponding gripper 210. The groove b is disposed opposite to the insert 211 on the corresponding side surface of the adjacent gripper 210, and similarly, the groove b extends from the end of the gripper 210 to the corresponding flexible portion 220 along the extending direction of the corresponding gripper 210. When the socket 100 is retracted and compressed, the insert 211 is embedded into the corresponding groove b on the adjacent side, which strengthens the connection between adjacent claws 210 and further improves the sealing and shielding performance of the socket 100. In one embodiment, each insert 211 extends further into the corresponding flexible part 220 by a predetermined distance, and correspondingly, the adjacent groove b extends further into the corresponding flexible part 220 by a predetermined distance, thereby avoiding the formation of gaps between the fitting structure and the corresponding flexible part 220 during application, which would lead to a decrease in shielding performance.

[0031] Furthermore, each gripper 210 is also provided with a sealing layer 230. The sealing layer 230 adheres to the outer surface of the gripper 210, and one side of the sealing layer 230 extends outward by a predetermined width toward the corresponding side edge of the gripper 210 to form an overlap portion 231. When the sleeve portion 100 is closed and compressed, adjacent grippers 210 engage and connect, and the overlap portion 231 of the sealing layer 230 overlaps with the surface of the adjacent gripper 210, thereby enabling the sealing layer 230 to further seal the joint of adjacent grippers 210, and further enhance the sealing and shielding performance of the shielding ring 10. Specifically, based on the shielding ring 10 as a whole, the sealing layer 230 extends from the end of the gripper 210 to the beginning of the gripper 210, so that the sealing layer 230 can fully cover the clearance groove a in the length direction.

[0032] Furthermore, the socket 100 includes a mating structure disposed on the outer surface of the socket 100 and extending to the end of the socket 100. When the socket 100 is mated with a suitable connector, the mating structure can mate with the connector, thereby limiting the mating configuration between the connector and the socket 100 and preventing reverse connection or twisting between the socket 100 and the connector. Specifically, the mating structure includes an axial mating block 110 extending from the outer surface of the socket 100 to the end of the socket 100. Thus, when the socket 100 is connected to the connector, the end of the axial mating block 110 can engage with the connector, thereby limiting the relative displacement between the socket 100 and the connector.

[0033] Furthermore, the mating structure also includes a circumferential mating block 120, which is disposed on the outer surface of the socket 100 along the circumference of the socket 100. When the shielding ring 10 is installed inside the connector housing, the circumferential mating block 120 can be mated and connected with the corresponding inner surface of the connector housing, thereby ensuring the installation stability of the shielding ring 10 inside the connector housing.

[0034] In summary, the sealing and shielding crimping ring of the female connector disclosed in this utility model connects to the connector head through a sleeve portion and is sleeved onto the outer surface of the wire harness through the crimping portion to achieve the limiting and sealing shielding functions of the shielding ring on the wire harness. The crimping portion includes several jaws. When the jaws are sleeved onto the wire harness, the clearance grooves allow sufficient compression space between adjacent jaws to complete the crimping closure according to the specific size of the clamped wire harness, thereby ensuring the clamping stability of the crimping portion on the wire harness. A flexible portion with a preset area is also provided between adjacent jaws. Several flexible portions correspond one-to-one with several clearance grooves, and the flexible portions are located at the bottom of the corresponding clearance grooves. The two sides of the flexible portions are connected to the adjacent jaws. Thus, when the jaws are compressed, the flexible portions can be squeezed and deformed under the compression of the adjacent jaws and fill the gaps between the jaws to further enhance the sealing performance of the sleeve portion, thereby enhancing the shielding capability of the shielding ring.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
