Description

Technical Field

[0001] The present invention belongs to the field of electrical connectors, and in particular relates to an outer conductor of an angle connector, an insulator of an angle connector, and an angle radio frequency connector. Background Art

[0002] When using RF connectors to transmit high-frequency, high-speed signals in vehicles, the inner and outer conductors of the contacts must maintain good electrical continuity in the direction of electromagnetic wave propagation in the high-frequency electromagnetic field. Furthermore, the insulating dielectric must be as uniform and stable as possible in the opposite direction of electromagnetic wave propagation. Therefore, any cuts or interruptions in the inner and outer conductors or insulating dielectric, perpendicular to the direction of propagation, will affect the quality of the signals transmitted by the RF connector.

[0003] However, when using angled RF connectors to transmit high-frequency, high-speed signals in vehicles, to ensure the operability of the assembly process between the angled RF connector and the cable, the outer conductor, inner conductor, insulator, and other components of the angled RF connector are typically assembled or formed from multiple separate parts. This reduces mold processing difficulty and improves assembly efficiency. As mentioned above, if the inner and outer conductor structures are separated or switched, their electrical continuity will inevitably be disrupted. To compensate for the electrical continuity of the inner and outer conductors, technicians often add electrical contacts or welds at the points where the separate parts are spliced ​​or assembled. However, even with these methods, the electrical continuity of the inner and outer conductors assembled from multiple separate parts is generally still inferior to that of a single-piece conductor. The same is true for insulators, which serve as insulating dielectrics. If the insulators are assembled from separate parts, gaps will inevitably appear at the points where the separate parts meet. Even if these gaps are corrected by methods such as potting or filling with rubber, the dielectric properties of the insulator will still fluctuate, causing fluctuations in electromagnetic wave propagation through the RF connector and affecting the quality of signal transmission.

[0004] The United States invention application with invention publication number US20230318231A1 discloses an angled subassembly of an angled connector. The inner conductor of the subassembly is obtained by integrally molding a first section and a second section arranged at an angle; its outer conductor is composed of two parts, a straight cylindrical part and a curved part. Although the straight cylindrical part and the curved part adopt an integrated structure, which reduces the number of outer conductor components, the outer conductor of the subassembly is still composed of separate parts in essence, and it is impossible to guarantee good electrical continuity on it. Corresponding to the outer conductor of the subassembly, the insulator of the subassembly is composed of two separate parts, a straight part and a curved part. Even if the curved part and the straight part adopt an integrated structure, the dielectric properties of the insulator will also mutate at the gap between the two parts. Therefore, the above structure still cannot guarantee good electrical continuity on the outer conductor, nor can it guarantee continuous and stable dielectric properties on the insulator.

[0042] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0043] The principle of the corner RF connector of the present invention is as follows:

[0044] A corner RF connector, the structure of which can refer to Figure 1-4 As shown, it includes an outer conductor 2 of an angle connector, an insulator 3 of an angle connector fixedly installed in the outer conductor 2 of the angle connector, and an inner conductor 4 fixedly installed in the insulator 3 of the angle connector. Figure 5 The outer conductor 2 of the angle connector can be referred to as Figure 6 As shown, it is an integrated sheet metal outer conductor, specifically including a plug-in barrel section 5 for plugging with an adapter connector. The plug-in barrel section 5 provides an inner cavity for the plug-in corner connector insulator 3 to be inserted from the back to the front, so as to facilitate the positioning and fixation of the corner connector insulator 3. The rear end of the plug-in barrel section 5 is connected with a bending arm 6, and the bending arm 6 is connected to the rear end of the plug-in barrel section 5 by a deformable connection portion 7. In this way, the rear port of the plug-in barrel section 5 can be kept open before the deformable connection portion 7 is bent to facilitate the insertion of the corner connector insulator 3. After the corner connector insulator 3 is inserted, the bending arm 6 is bent at the deformable connection portion 7 so that the corner connector insulator 3 can be buckled into the plug-in barrel section 5, thereby achieving fixed assembly of the outer conductor and the corner connector insulator 3. The outer conductor also has a connection portion for electrically connecting to the outer conductor of the cable to meet the functional requirements of the radio frequency connector. The above structure satisfies the assembly of the corner connector outer conductor 2 and the matching corner connector insulator 3 by bending an integrated sheet metal structure, avoiding the technical solution of separate assembly of the corner connector outer conductor 2 and effectively ensuring good electrical continuity on the corner connector outer conductor 2.

[0045] For reference Figure 8-11 As shown, the corner connector insulator 3 includes an integrally formed insertion section 8 and a corner section 9. The insertion section 8 is designed to be inserted into the inserting barrel section 5 of the corner connector outer conductor 2. It is provided with an inner conductor mounting hole 12, allowing the first section 10 of the corner inner conductor 4 to be inserted therein from back to front. The corner section 9 is disposed at the rear end of the insertion section 8 and arranged at an angle thereto. It is provided with a receiving slot 18 for receiving the second section 11 of the corner inner conductor 4. A covering arm 17 is also integrally connected to the rear end of the insertion section 8. The covering arm 17 extends away from the insertion direction to clear the rear end of the inner conductor mounting hole 12, thereby facilitating insertion of the inner conductor 4 into the inner conductor mounting hole 12. The covering arm 17 is bendable relative to the insertion section 8. When bent, it precisely covers and closes the opening of the receiving slot 18, thereby sealing the second section 11 of the corner inner conductor 4 within the receiving slot 18. The above structure uses an integrated insulating structure to fix and insulate the inner conductor 4, avoiding the technical solution of the corner connector insulator 3 being formed by separate parts. Therefore, it avoids the situation where the dielectric properties of the corner connector insulator 3 change at the gap of the separate assembly, and effectively ensures the consistency and continuity of the dielectric properties on the corner connector insulator 3.

[0046] It should be noted that the corner RF connector 1 described herein also includes the following two structures: the corner RF connector 1 includes a corner connector outer conductor 2, a corner connector insulator 3 fixedly mounted in the corner connector outer conductor 2, and an inner conductor 4 fixedly mounted in the corner connector insulator 3, wherein the corner connector outer conductor 2 adopts the aforementioned integrated structure, while the corner connector insulator 3 fixedly mounted in the corner connector outer conductor 2 and the inner conductor 4 fixedly mounted in the corner connector insulator 3 adopt a conventional split-piece structure; or the corner connector insulator 3 adopts the aforementioned integrated structure, while the corner connector outer conductor 2 and the inner conductor 4 fixedly mounted in the corner connector insulator 3 adopt a conventional split-piece structure. Furthermore, the number of inner conductors 4 on the corner RF connector 1 described herein can be configured according to specific needs. Therefore, a cable can be selected to suit the number of inner conductors 4 on the corner RF connector 1, using either a single-core or multi-core cable. The number and specific placement of the inner conductor mounting holes 12 on the corner connector insulator 3 also depend on the specific number and placement of the inner conductors 4.

[0047] In addition, the angled RF connector of the present invention can be set according to actual needs to have an angle between its upper incoming line direction and the outgoing line direction after electrical connection, such as 150 degrees, 120 degrees, 90 degrees, 60 degrees, etc. On this basis, after the bending arm 6 of the outer conductor 2 of the corner connector is bent into place, the angle between it and the plug barrel section 5 is also 150 degrees, 120 degrees, 90 degrees, 60 degrees, etc. as described above. When the corner connector insulator 3 inside the outer conductor 2 of the corner connector is the aforementioned integrated structure, the angle between its insertion section 8 and the corner section 9 is also 150 degrees, 120 degrees, 90 degrees, 60 degrees, etc. as described above. The first section 10 and the second section 11 of the corner inner conductor 4 are also arranged at an angle of 150 degrees, 120 degrees, 90 degrees, 60 degrees, etc. as described above.

[0048] By adopting the above scheme, the outer conductor 2 of the corner connector can be integrally formed to ensure good electrical continuity on the outer conductor 2 of the corner connector; and the insulator 3 of the corner connector can be integrally formed to ensure that the insulator 3 of the corner connector has continuous and consistent dielectric properties, thereby avoiding fluctuations in the propagation of electromagnetic waves on the corner RF connector 1 and ensuring good signal transmission quality on the corner RF connector 1.

[0049] Based on the above-mentioned principle, the embodiment 1 of the angled RF connector of the present invention is:

[0050] A corner RF connector, the structure of which can refer to Figure 1-4 As shown, it includes an outer conductor 2 of an angle connector, an insulator 3 of an angle connector fixedly installed in the outer conductor 2 of the angle connector, and an inner conductor 4 fixedly installed in the insulator 3 of the angle connector. Figure 5 The inner conductor 4 can be referred to as Figure 12 As shown, it is an integral bent structure, specifically comprising a first section 10 and a second section 11 arranged at an angle. The outer conductor 2 of the corner connector can be referred to Figure 6 As shown, it is an integrated sheet metal outer conductor, specifically including a plug-in barrel section 5 for plugging with an adapter connector. The rear end of the plug-in barrel section 5 is connected to a bending arm 6, and the bending arm 6 and the rear end of the plug-in barrel section 5 are connected by a deformable connecting portion 7. After the corner connector insulator 3 is inserted, the bending arm 6 is bent at the deformable connecting portion 7 so that the corner connector insulator 3 can be buckled into the plug-in barrel section 5. The outer conductor also has a connecting portion for electrically connecting to the outer conductor of the cable to meet the needs of the RF connector for transmitting signals. On this basis, the corner connector insulator 3 can refer to Figure 8-11As shown, it includes an integrally arranged insertion section 8 and a corner section 9. The insertion section 8 is used to be inserted into the plug-in barrel section 5 of the outer conductor 2 of the corner connector, and is provided with an inner conductor mounting hole 12 so that the first section 10 of the adapted corner inner conductor 4 can be inserted therein from the back to the front. In this embodiment, the first section 10 of the inner conductor 4 is used to be fixedly inserted into the inner conductor mounting hole 12. The first section 10 of the inner conductor 4 specifically includes a cylindrical section 13 and a cubic section 14, wherein the cylindrical section 13 is used for conductive plugging with the adapting connector, and the cubic section 14 is used for fixed installation and anti-rotation cooperation with the inner conductor mounting hole 12. The inner conductor mounting hole 12 corresponds to the cylindrical section 13 and the cubic section 14 on the first section 10 of the inner conductor 4 and is also specifically divided into a circular hole section 15 and a square hole section 16. The circular hole section 15 is used to adapt to the aforementioned cylindrical section 13, and the square hole section 16 and the aforementioned cubic section 14 are anti-rotation through the surfaces of the two. Convex wings are provided on both sides of the cubic section 14, and concave cavities are provided on the inner wall of the square hole section 16 corresponding to the convex wings. A bevel or arc surface is provided on the side of the convex wing facing the insertion direction of the inner conductor 4, so that the inner conductor 4 can be inserted into the inner conductor mounting hole 12 with interference fit. A stop surface is provided on the side of the convex wing facing away from the insertion direction of the inner conductor 4. After the inner conductor 4 is inserted into place, its convex wings are just stuck in the aforementioned concave cavity. At this time, the stop surface cooperates with the cavity wall of the aforementioned concave cavity to prevent the inner conductor 4 from slipping out of the inner conductor mounting hole 12 in the direction opposite to its insertion direction. At the same time, the cooperation between the convex wings and the concave cavity further prevents the tendency of the inner conductor 4 to rotate in the inner conductor mounting hole 12. The corner section 9 is provided at the rear end of the insertion section 8 and is arranged at an angle to the insertion section 8. A receiving groove 18 is provided thereon for accommodating the second section 11 of the adapted corner inner conductor 4. The rear end of the insertion section 8 is also integrally connected to a covering arm 17, which extends away from the insertion direction to clear the rear end opening of the inner conductor mounting hole 12, thereby facilitating the insertion of the inner conductor 4 into the inner conductor mounting hole 12. The covering arm 17 can be bent relative to the insertion section 8. After bending, it can just cover and close the notch of the receiving slot 18 to seal the second section 11 of the corner inner conductor 4 in the receiving slot 18. The above structure ensures good electrical continuity on the outer conductor 2 of the corner connector by making the outer conductor 2 of the corner connector an integral part; and ensures that the insulator 3 of the corner connector has continuous and consistent dielectric properties by making the insulator 3 of the corner connector an integral part, thereby avoiding fluctuations in the propagation of electromagnetic waves on the corner RF connector 1 and ensuring good signal transmission quality on the corner RF connector 1.

[0051] Another important point to note about this embodiment is that the plug-in barrel section 5 is specifically a rectangular barrel section. The bending arm 6 includes a main arm body 19 integrally connected to the plug-in barrel section 5 via a deformable connection portion 7, and vertical wing arms 20 located on either side of the main arm body 19. The vertical wing arms 20 can overlap the side wall of the plug-in barrel section 5 when the main arm body 19 is bent at the deformable connection portion 7. A buckle 21 is provided on one of the corresponding side walls of the vertical wing arm 20 and the plug-in barrel section 5, and a latch window 22 is provided on the other side wall to lock the connection when the main arm body 19 is bent at the deformable connection portion 7. Specifically, the buckle 21 can be provided on the portion of the vertical wing arm 20 corresponding to the side wall of the plug-in barrel section 5, and the latch window 22 can be provided on the portion of the side wall of the plug-in barrel section 5 corresponding to the vertical wing arm 20; alternatively, the latch window 22 can be provided on the portion of the vertical wing arm 20 corresponding to the side wall of the plug-in barrel section 5, and the buckle 21 can be provided on the portion of the side wall of the plug-in barrel section 5 corresponding to the vertical wing arm 20. Such a setting can ensure that after the main arm body 19 is bent at the deformed connection portion 7, its position relative to the plug-in barrel section 5 is fixed, thereby achieving a good positioning effect for the corner connector insulator 3 inside the plug-in barrel section 5. It is easy to imagine that for a permanently formed corner RF connector 1 that does not require disassembly, the vertical wing arm 20 and the corresponding side wall of the plug-in barrel section 5 can also be welded together after the main arm body 19 is bent at the deformed connection portion 7. It should be noted that when the two are welded by filling welding, a welding window needs to be opened at the corresponding position of the vertical wing arm 20 and the plug-in barrel section 5 on the outside to fill the solder. When the two are welded by laser welding, the vertical wing arm 20 and the plug-in barrel section 5 can be directly welded together without the need for a welding window. In addition, after the main arm body 19 is bent at the deformed connection portion 7, rivet points can also be processed by sheet metal stamping at the overlapping position of the vertical wing arm 20 and the corresponding side wall of the plug-in barrel section 5 so that the two can be fixed and maintained as one.

[0052] Based on the above-mentioned principle and embodiment 1, embodiment 2 of the angled RF connector of the present invention is as follows:

[0053] Based on the principle of the aforementioned scheme, the aforementioned plug-in barrel section 5 can be a rectangular barrel section, and the bending arm 6 can be composed of a main arm body 19 integrally connected to the plug-in barrel section 5 through a deformable connection portion 7 and vertical wing arms 20 located on the two side edges of the main arm body 19. Compared with Example 1, the key point of this embodiment is that the plug-in barrel section 5 is provided with a support arm 28 extending along its two side walls at its rear end. The support arm 28 is arranged at an angle to the plug-in barrel section 5 to accommodate the inner conductor 4 bent at an angle. The vertical wing arm 20 is also integrally connected to a wrapping wing arm 23 to wrap the support arm 28 when the main arm body 19 is bent, forming a wrapping shell that completely wraps the corner section 9 of the corner connector insulator 3 from the circumferential direction. In this way, the wrapping shell can provide a complete protection effect for the corner section 9 of the corner connector insulator 3, and it is also convenient to use the wrapping shell to position and fix the corner connector insulator 3. In addition, the cooperation between the wrapping wing arms 23 and the support arms 28 can make the main arm body 19 have better shape retention ability after bending, so that the wrapping shell can more reliably position and fix the corner connector insulator 3. It is easy to imagine that the bending arm 6 can also only include the main arm body 19 that is integrally connected to the plug-in barrel section 5 through the deformable connection part 7 and the vertical wing arms 20 located at the edges of the two sides of the main arm body 19. After bending, the main arm body 19 cooperates with the plug-in barrel section 5 in the manner described in Example 1 to fix its bending position relative to the plug-in barrel section 5. In addition, the two vertical wing arms 20 can be provided with wrapping wing arms 23, so that the two wrapping wing arms 23 are bent toward the middle position between the two to form the aforementioned wrapping shell.

[0054] When the corner RF connector 1 is assembled, the cable that is compatible with the corner RF connector 1 is first stripped and exposed, so that the cable end segments expose the cable core 27 and the cable shielding layer. It should be noted here that the shielding layer of the cable connected to the corner RF connector 1 usually includes a metal wire braided shielding layer 25 and a metal foil shielding layer 26. The inner conductor 4 of the corner RF connector 1 is fixed and conductively connected to the cable core 27. After the two are connected, the first section 10 of the inner conductor 4 is inserted into the inner conductor mounting hole 12 of the corner connector insulator 3, and the second section 11 is installed in the receiving groove 18 of the corner connector insulator 3. Then, the insertion section 8 of the corner connector insulator 3 is inserted into the plug-in barrel section 5 of the corner connector outer conductor 2. The bending arm 6 is bent at the deformed connection part 7, and the covering arm 17 of the corner connector insulator 3 is pressed to bend synchronously and cover and close the notch of the receiving groove 18, so that the corner connector insulator 3 completely wraps the inner conductor 4. The wrapping wing arms 23 on the outer conductor 2 of the corner connector now wrap around the support arms 28, forming a wrapping shell that completely circumferentially wraps around the corner section 9 of the insulator 3 of the corner connector; at the same time, the buckles 21 on the corresponding side walls of the vertical wing arms 20 and the plug-in barrel section 5 are engaged with the snap windows 22 to keep the main arm body 19 of the outer conductor 2 of the corner connector in the current bending position.

[0055] Based on the aforementioned structure, an encapsulating arm 29 can be extended from the lower end of the support arm 28, and an encapsulating arm wrapping wing 30 can be provided on the bending arm 6 to wrap around the encapsulating arm 29. This allows the exposed metal foil shielding layer 26 and the portion where the inner conductor 4 connects to the cable core 27 to be completely enclosed and protected by the encapsulating arm wrapping wing 30. The lower end portion of the exposed braided metal shielding layer 25 is compressed and shielded by the shield crimping ring 24 mounted thereon, while the upper end portion of the braided metal shielding layer 25 is turned outward and covered by the outer side of the shield crimping ring 24. The connection portion on the outer conductor 2 of the corner connector can include a shield wrapping wing 31 provided on the bending arm 6. The shield wrapping wing 31 compresses and wraps around the outermost surface of the braided metal shielding layer 25 corresponding to the shield crimping ring 24, thereby securing the braided metal shielding layer 25 and achieving a conductive connection between the braided metal shielding layer 25 and the outer conductor 2 of the corner connector. Cable sheath wrapping wings 32 can also be provided on the bending arm 6 to achieve relative fixation between the bending arm 6 and the cable. In addition to providing sealing and protection for the exposed sections of the cable, this arrangement also increases the number of fixed connection points between the corner connector outer conductor 2 and the cable, further strengthening the connection between the corner connector outer conductor 2 and the cable, preventing relative movement between the corner connector outer conductor 2 and the cable, and thereby preventing damage to the connection between the corner connector outer conductor 2 and the cable due to cable movement. It is readily conceivable that, if manufacturing costs are limited, a wire can also be used to connect the braided wire shield 25 and the corner connector outer conductor 2. The corner connector and cable are encapsulated as a single unit by a separate connector housing. The inner cavity of the connector housing is provided with a wire clamp for securing the cable insulation layer and the cable sheath. This clamp secures the cable during assembly of the connector housing. Alternatively, after assembly, the connector housing can be injection molded or glued to securely hold the cable and corner connector outer conductor 2 within the connector housing.

[0056] The parts not emphasized in this embodiment are consistent with those in Example 1.

[0057] Based on the above-mentioned principle and embodiments 1 and 2, embodiment 3 of the angled RF connector of the present invention is as follows:

[0058] Compared with Example 1 and Example 2, the key point of this embodiment is that reference can be made to Figure 7As shown, the end of the plug barrel section 5 facing the plugging direction is provided with multiple axially extending slots 34. The portion between adjacent slots 34 forms a cantilever arm. The cantilever arm extends outward at an angle and forms an elastic contact arm 33 for elastically contacting the mating connector. This allows the slots 34 to form multiple electrical contact points between the corner connector outer conductor 2 and the mating end of the mating connector. The elasticity of the elastic contact arm 33 also ensures a reliable electrical connection between the corner connector outer conductor 2 and the mating end of the mating connector. The elastic contact arm 33 retracts during mating to prevent the electrical contact points from interfering with the mating end of the corner connector 2. A relief groove 35 is provided on the corner connector insulator 3 corresponding to the elastic contact arm 33 to prevent the corner connector insulator 3 from interfering with the retraction of the elastic contact arm 33. Of course, it is readily conceivable that the end surface of the plug barrel section 5 facing the plugging direction could also be formed with multiple contact bumps by sheet metal stamping. When the outer conductor 2 of the angle connector is plugged into the plug-in end of the adapter connector, the contact convex bump is inserted into the plug-in end of the adapter connector along with the outer conductor 2 of the angle connector to achieve electrical connection between the two.

[0059] On the basis of the aforementioned structure, an inward folded edge 36 can be provided at the end of the plug-in direction of the plug-in barrel section 5, so as to guide the plug-in of the outer conductor 2 of the corner connector and the plug-in end of the adapter connector through the inward folded edge 36. In order to prevent the aforementioned elastic contact arm 33 from interfering with the plug-in, the aforementioned inward folded edge 36 is located forward relative to the elastic contact arm 33 in its plug-in direction. Such a setting can facilitate the plug-in of the corner RF connector 1 and the adapter connector, which is beneficial to improving the plug-in efficiency. A step 37 is provided at the end of the corner connector insulator 3 facing the plug-in direction corresponding to the inward folded edge 36, so that the step 37 and the inward folded edge 36 can cooperate to further stop the corner connector insulator 3. In addition, if the cost is limited, the end of the plug-in direction of the plug-in barrel section 5 can also have only straight edges to simplify the molding process of the plug-in barrel section 5.
