Description

Technical Field

[0001] This invention relates to the technical field of radio frequency coaxial connectors, and in particular to a bent connector and its manufacturing method. Background Technology

[0002] With the continuous development of technology, the frequency of radio frequency signals transmitted by board-to-board connectors is getting higher and higher. Traditional right-angle connectors use spring pins for grounding, which has the problem of poor grounding effect; the gap between the connector and the board makes the electromagnetic shielding of the connector poor, which in turn makes the signal isolation of the connector poor.

[0003] Moreover, for high-frequency signal transmission, the spring pin grounding method has poor impedance matching performance, and is especially unsuitable for applications with multiple channels and high frequencies. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bent connector with good grounding effect, signal isolation and impedance matching performance and its manufacturing method.

A metal spring is located in the crimping groove and crimped to the metal housing; the metal spring has a mounting groove. A grounding protection cap is located in the crimping groove and sleeved on the outer peripheral wall of the metal spring. The grounding protection cap is slidably connected to the metal spring, and one end of the grounding protection cap protrudes from the abutment surface. An elastic element is located inside the crimping groove. The elastic element is sleeved on the outside of the metal spring, and both ends of the elastic element abut against the metal spring and the grounding protection cap, respectively. The adapter pin is located inside the metal housing; A medium body is located in the mounting groove and is fixedly connected to the metal spring, and a mounting hole is formed in the medium body; A hair button is located inside the mounting hole, with the first end of the hair button located outside the medium body and abutting against the adapter pin; A central protective cap is located inside the mounting hole and slidably connected to the medium body, with one end of the central protective cap abutting the second end of the button, and the other end of the central protective cap protruding from the abutting surface through the mounting hole; a grounding protective cap is arranged around the central protective cap. When the contact surface abuts against the circuit board, the grounding protection cap slides into the metal housing relative to the metal spring and compresses the elastic element, and the central protection cap compresses the bobbin towards the mounting hole.

[0006] In one embodiment, the inner peripheral wall of the end of the grounding protection cap located within the crimping groove is provided with a pressing conical surface; and / or, The outer peripheral wall of the end of the metal spring adjacent to the abutment surface is provided with a pressure-guiding curved surface.

[0007] In one embodiment, the grounding protection cap is elastically fitted onto the outer peripheral wall of the metal spring.

[0008] In one embodiment, the inner wall of the mounting groove is provided with a first limiting step, and the outer peripheral wall of the medium body is provided with a first anti-detachment protrusion. The first limiting step is used to limit and fix the first anti-detachment protrusion.

[0009] In one embodiment, the inner wall of the mounting hole is formed with a second limiting step, and the outer peripheral wall of the central protective cap is provided with a second anti-detachment protrusion. The second anti-detachment protrusion is used to abut against the second limiting step before the abutting surface abuts against the circuit board.

[0010] In one embodiment, the outer peripheral wall of the metal spring is provided with a third limiting step, and the inner peripheral wall of the grounding protection cap is provided with a barbed step, the barbed step being used to abut against the third limiting step before the abutting surface abuts against the circuit board.

[0011] In one embodiment, the outer peripheral wall of the metal spring is further provided with a fourth limiting step, the elastic element is located between the third limiting step and the fourth limiting step, and one end of the elastic element abuts against the fourth limiting step, and the other end of the elastic element abuts against the grounding protection cap.

[0012] In one embodiment, the metal housing is coaxially arranged with the metal spring.

[0013] In one embodiment, the heat resistance temperature of the medium is 250°C to 300°C.

[0014] A method for manufacturing a bent connector, used to manufacture the bent connector described in any of the above embodiments, the manufacturing method comprising: The central protective cap and the hair button are assembled into the mounting hole, so that the hair button abuts against the end face of the central protective cap; The medium is installed in the mounting slot; The metal spring is pressed into the crimping groove, so that the metal spring is pressed against the metal shell, and the rough button abuts against the adapter pin; The elastic element is sleeved on the outside of the metal spring; The grounding protection cap is pressed into the crimping groove and sleeved on the outer peripheral wall of the metal spring, so that the grounding protection cap and the metal spring are slidably connected, and the two ends of the elastic member abut against the metal spring and the grounding protection cap respectively.

[0015] Compared with the prior art, the present invention has at least the following advantages: 1. In the above-mentioned bent connector, the grounding protection cap is located in the crimping groove and sleeved on the outer peripheral wall of the metal spring. The grounding protection cap is slidably connected to the metal spring. One end of the grounding protection cap protrudes from the abutment surface. The elastic element is sleeved on the outside of the metal spring, and the two ends of the elastic element abut against the metal spring and the grounding protection cap respectively. When the grounding protection cap abuts against the circuit board, the elastic element is compressed, thereby enabling the grounding protection cap to float relative to the metal spring and make contact with the ground. Since the center protection cap is located in the mounting hole and is slidably connected to the dielectric, one end of the center protection cap abuts against the second end of the button, and the other end of the center protection cap protrudes from the abutting surface through the mounting hole, so that the center protection cap compresses the button when the abutting surface abuts against the circuit board, thereby enabling the center protection cap to float and make conductive contact relative to the dielectric. 2. When the contact surface abuts against the circuit board, the grounding protection cap slides into the metal housing relative to the metal spring and compresses the elastic element. The center protection cap compresses the button towards the mounting hole, so that both the grounding protection cap and the center protection cap can be elastically compressed when the contact surface abuts against the circuit board. This gives both the grounding protection cap and the center protection cap good floating performance, and also gives the bent connector good axial tolerance performance. This enables the bent connector to communicate and ground reliably, avoiding the problem of poor grounding effect of the bent connector. At the same time, it realizes the solderless interconnection between the bent connector and the circuit board. 3. Because the grounding protection cap can elastically abut against the circuit board through the elastic element, the grounding protection cap can effectively abut against the circuit board when the abutting surface abuts against the circuit board. In addition, the grounding protection cap is set around the central protection cap, which avoids the problem of poor electromagnetic shielding of the connector, thus improving the signal isolation of the connector. 4. Compared to the spring pin grounding method, the above-mentioned bent connector conducts electricity to the circuit board through the grounding protection cap and communicates with the circuit board through the center protection cap. The center protection cap is electrically connected to the adapter pin through the button to form a communication path. In addition, the metal spring is insulated from the communication path through the dielectric body, which improves the impedance matching performance of the bent connector. It is especially suitable for high-frequency signal use in application scenarios with many channels and high frequency. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] This application provides a bent connector, including a metal shell, a metal spring, a grounding protection cap, an elastic element, an adapter pin, a dielectric body, a snap fastener, and a center protection cap; the metal shell has an abutment surface with a crimping groove for abutting against a circuit board; the metal spring is located in the crimping groove and crimped against the metal shell, and the metal spring has a mounting groove; the grounding protection cap is located in the crimping groove and sleeved on the outer peripheral wall of the metal spring, the grounding protection cap is slidably connected to the metal spring, and one end of the grounding protection cap protrudes from the abutment surface; the elastic element is located in the crimping groove, sleeved on the outside of the metal spring, and both ends of the elastic element abut against the metal spring and the grounding protection cap respectively; an adapter pin... A pin is disposed within the metal housing; a dielectric body is located within the mounting groove and fixedly connected to the metal spring, and a mounting hole is formed within the dielectric body; a hair button is located within the mounting hole, with its first end located outside the dielectric body and abutting against the adapter pin; a grounding protection cap is disposed around the central protection cap; the central protection cap is located within the mounting hole and slidably connected to the dielectric body, with one end of the central protection cap abutting against the second end of the hair button, and the other end of the central protection cap protruding from the abutting surface through the mounting hole; when the abutting surface abuts against the circuit board, the grounding protection cap slides into the metal housing relative to the metal spring and compresses the elastic element, and the central protection cap compresses the hair button toward the mounting hole.

[0022] In the aforementioned bent connector, the grounding protection cap is located within the crimping groove and sleeved on the outer peripheral wall of the metal spring. The grounding protection cap is slidably connected to the metal spring, with one end protruding from the contact surface. The elastic element is sleeved on the outside of the metal spring, and both ends of the elastic element abut against the metal spring and the grounding protection cap respectively. This allows the grounding protection cap to compress the elastic element when the contact surface abuts against the circuit board, thereby enabling the grounding protection cap to float and make contact with the ground relative to the metal spring. Similarly, the central protection cap is located within the mounting hole and slidably connected to the dielectric. One end of the central protection cap abuts against the second end of the snap fastener, and the other end of the central protection cap protrudes from the contact surface through the mounting hole. This allows the central protection cap to compress the snap fastener when the contact surface abuts against the circuit board, thereby enabling the central protection cap to float and make contact with the dielectric for conductivity.

[0023] When the contact surface abuts against the circuit board, the grounding protection cap slides into the metal housing relative to the metal spring and compresses the elastic element. The center protection cap compresses the button towards the mounting hole, so that both the grounding protection cap and the center protection cap can be elastically compressed when the contact surface abuts against the circuit board. This gives both the grounding protection cap and the center protection cap good floating performance, and also gives the bent connector good axial tolerance performance. This enables the bent connector to communicate and ground reliably, avoiding the problem of poor grounding effect of the bent connector. At the same time, it realizes the solderless interconnection between the bent connector and the circuit board. Because the grounding protection cap can elastically abut against the circuit board through the elastic element, the grounding protection cap can effectively abut against the circuit board when the abutting surface abuts against the circuit board. In addition, the grounding protection cap is set around the central protection cap, which avoids the problem of poor electromagnetic shielding of the connector, thus improving the signal isolation of the connector.

[0024] Compared to the spring-pin grounding method, the aforementioned bent connector conducts electricity to the circuit board through the grounding protection cap and communicates with the circuit board through the center protection cap. The center protection cap is electrically connected to the adapter pin through a button to form a communication path. In addition, the metal spring is insulated from the communication path through the dielectric body, which improves the impedance matching performance of the bent connector. It is especially suitable for high-frequency signal usage requirements in application scenarios with many channels and high frequencies.

[0025] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments: like Figure 1 and Figure 2 As shown, one embodiment of the bent connector 10 includes a metal housing 100, a metal spring 200, a grounding protection cap 300, an elastic element 400, an adapter pin 500, a dielectric body 600, a hair button 700, and a center protection cap 800.

[0026] The metal housing 100 has an abutment surface 102, which has a crimping groove 1022 for abutting against the circuit board. When the bent connector 10 is assembled between boards, one end of the bent connector 10 contacts one of the circuit boards through the abutment surface 102, while the connection between the other end of the bent connector 10 and the other circuit board is prior art and will not be described in detail here.

[0027] In one embodiment, the metal spring 200 is located within the crimping groove 1022 and crimped against the metal housing 100, so that the metal spring 200 is crimped and assembled within the metal housing 100. A grounding protection cap 300 is located within the crimping groove 1022 and sleeved on the outer peripheral wall of the metal spring 200. The grounding protection cap 300 is slidably connected to the metal spring 200, and one end of the grounding protection cap 300 protrudes from the abutment surface 102. An elastic element 400 is located within the crimping groove 1022, sleeved on the outside of the metal spring 200, and both ends of the elastic element 400 abut against the metal spring 200 and the grounding protection cap 300, respectively. When the abutment surface 102 abuts against the circuit board, the grounding protection cap 300 moves relative to the metal spring 200 towards the crimping groove 1022, i.e., along... Figure 2As shown, the elastic element 400 slides in the F direction, and is compressed by the grounding protection cap 300, causing the grounding protection cap 300 to float elastically and abut against the grounding contact of the circuit board. In this embodiment, the elastic element 400 is a helical spring. In other embodiments, the elastic element 400 can also be an elastic sleeve.

[0028] like Figures 1 to 2 As shown, in one embodiment, the adapter pin 500 is disposed within the metal housing 100; the metal spring 200 has a mounting groove 202, the medium body 600 is located within the mounting groove 202 and is fixedly connected to the metal spring 200; the medium body 600 has a mounting hole 602, and the bobby pin 700 is located within the mounting hole 602, so that the bobby pin 700 is fixedly connected to the medium body 600, while simultaneously insulating the bobby pin 700 from the metal spring 200. The first end of the bobby pin 700 is located outside the medium body 600 and abuts against the adapter pin 500, so that the bobby pin 700 is electrically connected to the adapter pin 500.

[0029] like Figures 1 to 2 As shown, in one embodiment, the central protective cap 800 is located within the mounting hole 602 and slidably connected to the dielectric body 600. One end of the central protective cap 800 abuts against the second end of the button 700, and the other end of the central protective cap 800 protrudes from the contact surface 102 through the mounting hole 602, so that both ends of the central protective cap 800 are electrically connected to the conductive contacts of the button 700 and the circuit board, respectively. The grounding protective cap 300 is arranged around the central protective cap 800, so that the grounding protective cap 300 can better ground and shield the conductivity of the central protective cap 800. When the contact surface 102 abuts against the circuit board, the grounding protective cap 300 slides into the metal housing 100 relative to the metal spring 200 and compresses the elastic member 400, and the central protective cap 800 moves towards the mounting hole 602, i.e., along... Figure 2 The F-direction compression of the button 700 allows both the grounding protection cap 300 and the center protection cap 800 to float and contact the circuit board surface, thereby achieving floating contact. This improves the axial tolerance performance of the bent connector 10, avoids the problem of poor grounding effect of the bent connector 10, and realizes solderless interconnection between the bent connector 10 and the circuit board.

[0030] In the aforementioned bent connector 10, the grounding protection cap 300 is located within the crimping groove 1022 and sleeved on the outer peripheral wall of the metal spring 200. The grounding protection cap 300 and the metal spring 200 are slidably connected. One end of the grounding protection cap 300 protrudes from the abutment surface 102. The elastic member 400 is sleeved on the outside of the metal spring 200, and both ends of the elastic member 400 abut against the metal spring 200 and the grounding protection cap 300, respectively. This causes the grounding protection cap 300 to compress the elastic member 400 when the abutment surface 102 abuts against the circuit board, thereby... The grounding protection cap 300 can float and make contact with the ground relative to the metal spring 200. Since the central protection cap 800 is located in the mounting hole 602 and is slidably connected to the dielectric body 600, one end of the central protection cap 800 abuts against the second end of the button 700, and the other end of the central protection cap 800 protrudes from the abutting surface 102 through the mounting hole 602. When the abutting surface 102 abuts against the circuit board, the central protection cap 800 compresses the button 700, thereby enabling the central protection cap 800 to float and make contact with the dielectric body 600 for conduction.

[0031] When the contact surface 102 abuts against the circuit board, the grounding protection cap 300 slides into the metal housing 100 relative to the metal spring 200 and compresses the elastic element 400, causing the grounding protection cap 300 to float through the elastic element 400. The center protection cap 800 compresses the button 700 towards the mounting hole 602, causing the center protection cap 800 to float through the button 700. In this way, both the grounding protection cap 300 and the center protection cap 800 can be elastically compressed when the contact surface 102 abuts against the circuit board, giving both the grounding protection cap 300 and the center protection cap 800 good floating performance. This also gives the bent connector 10 good tolerance performance, thereby enabling the bent connector 10 to communicate and ground reliably, avoiding the problem of poor grounding effect of the bent connector 10, and realizing solderless interconnection between the bent connector 10 and the circuit board.

[0032] Since the grounding protection cap 300 can elastically abut against the circuit board through the elastic element 400, the grounding protection cap 300 can effectively abut against the circuit board when the abutting surface 102 abuts against the circuit board. In addition, the grounding protection cap 300 is arranged around the central protection cap 800, which avoids the problem of poor electromagnetic shielding of the connector, that is, improves the signal isolation of the connector.

[0033] Compared to the spring pin grounding method, the aforementioned bent connector 10 conducts electricity to the circuit board through the grounding protection cap 300 and communicates with the circuit board through the center protection cap 800. The center protection cap 800 is electrically connected to the adapter pin 500 through the button 700 to form a communication path. In addition, the metal spring 200 is insulated from the communication path through the dielectric body 600, which improves the impedance matching performance of the bent connector 10. It is especially suitable for high-frequency signal usage requirements in application scenarios with multiple channels and high frequencies.

[0034] like Figures 1 to 2 As shown, in one embodiment, the dielectric 600 is made of an insulating material. For example, the dielectric 600 is made of polyimide (i.e., PI) or liquid crystal polymer (i.e., LCP), giving the dielectric 600 good insulation and heat resistance properties.

[0035] like Figures 1 to 2 As shown, the mounting hole 602 is further formed at the center of the medium body 600, that is, the center line of the mounting hole 602 is collinear with the center line of the medium body 600, so that the central protective cap 800 and the button 700 are both coaxially arranged with the medium body 600, thereby making the central protective cap 800 coaxial with the metal spring 200. In addition, the grounding protective cap 300 is sleeved on the outer peripheral wall of the metal spring 200, so that the grounding protective cap 300 is coaxial with the central protective cap 800.

[0036] like Figures 1 to 2 As shown, in one embodiment, the inner peripheral wall of the end of the grounding protection cap 300 located within the crimping groove 1022 is provided with a pressing conical surface 302. This reduces the resistance of the grounding protection cap 300 being crimped and assembled onto the outer peripheral wall of the metal spring 200 through the crimping groove 1022, thereby improving the smoothness of the crimping between the grounding protection cap 300 and the metal spring 200, and simultaneously improving the reliability of the assembly between the grounding protection cap 300 and the metal spring 200, preventing the grounding protection cap 300 from falling off the metal spring 200. In this embodiment, the pressing conical surface 302 is a chamfered right-angled surface, and the angle of the pressing conical surface 302 is 30°~60°. In other embodiments, the pressing conical surface 302 can also be replaced by a pressing rounded corner surface. And / or, like Figures 1 to 2 As shown, in one embodiment, the outer peripheral wall of the metal spring 200 near the end of the abutment surface 102 is provided with a pressure-guiding curved surface 204, so that the grounding protection cap 300 can be more smoothly pressed and assembled onto the outer peripheral wall of the metal spring 200 through the end of the metal spring 200.

[0037] like Figures 1 to 2As shown, in one embodiment, the grounding protection cap 300 is elastically sleeved on the outer peripheral wall of the metal spring 200, allowing the grounding protection cap 300 to reliably slide and be sleeved on the metal spring 200, thus better preventing the grounding protection cap 300 from falling off relative to the metal spring 200. In this embodiment, after the grounding protection cap 300 is sleeved and assembled on the outer peripheral wall of the metal spring 200, the metal spring 200 is heat-treated to make the head of the metal spring 200 bulge. This exerts a certain pressure on the side wall of the grounding protection cap 300, ensuring reliable contact between the grounding protection cap 300 and the metal spring 200. This allows the grounding protection cap 300 to rub against the metal spring 200 during sliding relative to it, preventing the grounding protection cap 300 from easily deflecting during sliding relative to the metal spring 200.

[0038] like Figures 1 to 3 As shown, in one embodiment, the inner wall of the mounting groove 202 is formed with a first limiting step 2022, and the outer peripheral wall of the medium body 600 is provided with a first anti-detachment protrusion 604. The first limiting step 2022 is used to limit and fix the first anti-detachment protrusion 604, so that the medium body 600 is reliably limited and fixed in the mounting groove 202.

[0039] like Figures 1 to 2 As shown, in one embodiment, the inner wall of the mounting hole 602 is formed with a second limiting step 6022, and the outer peripheral wall of the central protective cap 800 is provided with a second anti-detachment protrusion 802. The second anti-detachment protrusion 802 is used to abut against the second limiting step 6022 before the abutting surface 102 abuts against the circuit board, so as to limit the floating of the central protective cap 800 and prevent the central protective cap 800 from detaching from the mounting hole 602. At the same time, it ensures that the central protective cap 800 reliably abuts against and is electrically connected to the end face of the button 700.

[0040] like Figures 1 to 2 As shown, in one embodiment, the outer peripheral wall of the metal spring 200 is provided with a third limiting step 205, and the inner peripheral wall of the grounding protection cap 300 is provided with a barbed step 304. The barbed step 304 is used to abut against the third limiting step 205 before the abutting surface 102 abuts against the circuit board, so that the grounding protection cap 300 and the metal spring 200 are reliably limited to prevent the grounding protection cap 300 from falling off. At the same time, this assembly method greatly reduces the external size of the connector, meets the size requirements of the connector in a narrow space, and thus allows the grounding protection cap 300 to be reliably slidably connected to the metal spring 200.

[0041] like Figures 1 to 3As shown, in one embodiment, the outer peripheral wall of the metal spring 200 is further provided with a fourth limiting step 207. The elastic member 400 is located between the third limiting step 205 and the fourth limiting step 207, with one end of the elastic member 400 abutting against the fourth limiting step 207 and the other end of the elastic member 400 abutting against the grounding protection cap 300. In this embodiment, the end faces of the fourth limiting step 207 and the grounding protection cap 300 are arranged opposite to each other, and the two ends of the elastic member 400 abut against the end faces of the fourth limiting step 207 and the grounding protection cap 300, respectively.

[0042] like Figures 1 to 3 As shown, in one embodiment, the metal housing 100 and the metal spring 200 are coaxially arranged, which improves the coaxiality of the bent connector 10. Since the metal housing 100 and the metal spring 200 are coaxially arranged, the elastic element 400, the dielectric body 600 and the grounding protection cap 300 assembled on the inner and outer sides of the metal spring 200 have good coaxiality. Furthermore, since the central protection cap 800 and the button 700 are both located in the mounting hole 602, the central protection cap 800 and the grounding protection cap 300 are reliably coaxially arranged, thereby realizing the transmission of coaxial radio frequency signals.

[0043] In one embodiment, the bent connector 10 is a bent ring-shaped floating ground button connector for vertical interconnection, which realizes vertical interconnection transmission of signals. In addition, the grounding protection cap 300 and the circuit board ring floating ground, that is, the grounding protection cap 300 and the circuit board ring elastic ground, improve the grounding shielding performance of the bent connector 10.

[0044] In one embodiment, the heat resistance temperature of the dielectric body 600 is 250°C to 300°C, which gives the dielectric body 600 good high temperature resistance, thereby giving the bent connector 10 good high temperature resistance.

[0045] Furthermore, the grounding protection cap 300 is a metal grounding protection cap, meaning it is made of metal. The elastic element 400 is a helical spring. Grounding floating is achieved through the contact between the grounding protection cap 300 and the elastic element 400. The grounding protection cap 300 is fixed by abutting against the third limiting step 205 through the barbed step 304 of the grounding protection cap 300, preventing the grounding protection cap 300 from falling off during use. The center protection cap 800 achieves floating contact of the center channel by compressing the button 700.

[0046] Furthermore, the floating amount of the center protective cap 800 relative to the dielectric body 600 is the first floating amount, and the floating amount of the grounding protective cap 300 relative to the metal spring 200 is the second floating amount. Both the first and second floating amounts are greater than or equal to the preset floating amount, which effectively compensates for the axial gap at the product mating end face caused by the installation accuracy of the bent connector 10 and the processing error of the circuit board. When the cumulative axial tolerance is within the predetermined tolerance range, the floating redundancy design of the center protective cap 800 and the grounding protective cap 300 can ensure reliable signal transmission and reliable grounding contact. In this embodiment, the first floating amount and the second floating amount are equal, the preset floating amount is greater than or equal to 0.4 mm, and the predetermined tolerance range is less than or equal to 0.4 mm.

[0047] like Figures 1 to 4 As shown, this application also provides a method for manufacturing a bent connector 10, used to manufacture the bent connector 10 described in any of the above embodiments. Further, the manufacturing method includes some or all of the following steps: S101, the central protective cap 800 and the button 700 are assembled into the mounting hole 602, so that the button 700 abuts against the end face of the central protective cap 800, thereby making the button 700 electrically connected to the central protective cap 800. In this embodiment, the step of assembling the central protective cap 800 and the button 700 into the mounting hole 602 specifically involves assembling the central protective cap 800 and the button 700 into the mounting hole 602, and making the second anti-detachment protrusion 802 on the outer peripheral wall of the central protective cap 800 abut against the second limiting step 6022 of the mounting hole 602. In one embodiment, the central protective cap 800 and the button 700 are coaxially arranged, so that the central protective cap 800 and the button 700 can reliably contact and conduct electricity.

[0048] S103, the medium body 600 is installed in the mounting groove 202, so that the medium body 600 is assembled in the metal spring 200; in this embodiment, the step of installing the medium body 600 in the mounting groove 202 is specifically as follows: the medium body 600 is installed in the mounting groove 202, so that the first anti-detachment protrusion 604 on the outer peripheral wall of the medium body 600 contacts and abuts against the first limiting step 2022 of the mounting groove 202, thereby reliably limiting and fixing the medium body 600 in the mounting groove 202.

[0049] S105, the metal spring 200 is pressed into the crimping groove 1022, so that the metal spring 200 is crimped with the metal shell 100, and the bobby button 700 abuts against the adapter pin 500, thereby making the bobby button 700 electrically connected to the adapter pin 500.

[0050] S107, the elastic element 400 is sleeved on the outside of the metal spring 200; in this embodiment, the step of sleeved on the outside of the metal spring 200 specifically involves: sleeved on the outside of the metal spring 200, so that one end of the elastic element 400 contacts the third limiting step 205 of the outer peripheral wall of the metal spring 200.

[0051] S109, the grounding protection cap 300 is pressed into the crimping groove 1022 and sleeved onto the outer peripheral wall of the metal spring 200, so that the grounding protection cap 300 and the metal spring 200 are slidably connected. The two ends of the elastic member 400 abut against the metal spring 200 and the grounding protection cap 300 respectively. In this embodiment, the inner peripheral wall of the grounding protection cap 300 is provided with a barbed step 304. Before the abutting surface 102 abuts against the circuit board, the barbed step 304 abuts against the third limiting step 205 of the outer peripheral wall of the metal spring 200, so that the grounding protection cap 300 and the metal spring 200 are reliably limited to prevent the grounding protection cap 300 from falling off. At the same time, this assembly method greatly reduces the external size of the connector and meets the size requirements of the connector in a confined space. When the bent connector 10 is assembled on the contact surface 102, the grounding protection cap 300 moves relative to the metal spring 200 into the crimping groove 1022 and compresses the elastic element 400, causing the elastic element 400 to deform under pressure.

[0052] Furthermore, after step S109, the manufacturing method further includes: heat-treating the end of the metal spring 200 adjacent to the contact surface 102, so that the head of the metal spring 200 is in an expanded state, which generates a certain pressure on the side wall of the grounding protection cap 300, ensuring reliable contact between the grounding protection cap 300 and the metal spring 200, so that the grounding protection cap 300 rubs against the metal spring 200 during the sliding process relative to the metal spring 200, and avoiding the situation where the grounding protection cap 300 is prone to deflection during the sliding process relative to the metal spring 200.

[0053] Further, prior to step S105, the manufacturing method further includes: assembling the adapter pin 500 within the crimp groove 1022, such that one end of the adapter pin 500 is welded and fixed to the conductive end of the conductive cable 1200 at the other end of the right-angle connector 10. In this embodiment, the end of the adapter pin 500 furnishing away from the button is welded to the conductive cable. See also... Figure 5 Furthermore, the adapter pin 500 has a U-shaped welding groove 501 at the end away from the button, and the conductive end of the conductive cable is located in the U-shaped welding groove and welded to the adapter pin 500, so that the adapter pin 500 is reliably welded to the conductive cable.

[0054] Furthermore, the adapter pin 500 is coaxially arranged with the end of the metal housing that has an abutment surface, so that the adapter pin 500 and the button are coaxially arranged, allowing the adapter pin 500 to abut against the end of the button in a better manner.

[0055] Furthermore, the bent connector 10 also includes an insulating positioning sleeve 900. The inner peripheral wall of the crimping groove 1022 is provided with a positioning groove 104. The insulating positioning sleeve 900 is disposed on the inner wall of the positioning groove and is sleeved onto the outer peripheral wall of the adapter pin 500, so that the adapter pin 500 and the end of the metal housing with the abutment surface are well coaxially arranged. Furthermore, the outer peripheral wall of the adapter pin 500 is formed with a locking groove 502, and the insulating positioning sleeve 900 is embedded in the locking groove 502, so that the adapter pin 500 and the insulating positioning sleeve 900 are reliably assembled and connected.

[0056] Furthermore, a fifth limiting step 1023 is formed on the inner peripheral wall of the crimping groove 1022. The end face of the metal spring 200 abuts against the fifth limiting step 1023 and the insulating positioning sleeve 900, so that the metal spring 200 is reliably crimped and assembled inside the metal shell 100, while the insulating positioning sleeve 900 is reliably pressed and limited to the end face of the metal spring 200 and the fifth limiting step 1023.

[0057] Furthermore, a crimping groove 1022 is formed through the metal housing 100 to facilitate the forming of the crimping groove 1022 and to facilitate the welding operation between the adapter pin 500 and the conductive cable. In this embodiment, the bent connector 10 also includes a cover plate 1100. A snap-fit ​​groove 109 is formed on the outer peripheral wall of the metal housing 100, which surrounds the crimping groove 1022. The cover plate is snapped into the snap-fit ​​groove. After the welding operation between the adapter pin 500 and the conductive cable, the cover plate is snapped into the snap-fit ​​groove, so that the cover plate seals the opening of the snap-fit ​​groove away from the contact surface.

[0058] Furthermore, the other end of the metal casing 100 is provided with a cable socket 1025 communicating with the crimping groove 1022, and the conductive cable 1200 is inserted into the cable socket. In this embodiment, the metal casing 100 is also provided with a welding fixing hole 1026 so that the conductive cable can be reliably welded and fixed into the cable socket through the welding fixing hole 1026, and the guide wire can be reliably welded and fixed to the adapter pin 500.

[0059] Compared with the prior art, the present invention has at least the following advantages: 1. In the aforementioned bent connector 10, the grounding protection cap 300 is located in the crimping groove 1022 and sleeved on the outer peripheral wall of the metal spring 200. The grounding protection cap 300 and the metal spring 200 are slidably connected. One end of the grounding protection cap 300 protrudes from the abutment surface 102. The elastic member 400 is sleeved on the outside of the metal spring 200, and both ends of the elastic member 400 abut against the metal spring 200 and the grounding protection cap 300 respectively. When the grounding protection cap 300 abuts against the circuit board at the abutment surface 102, the elastic member 400 is compressed, thereby enabling the grounding protection cap 300 to float relative to the metal spring 200 and make contact with the ground. Since the central protective cap 800 is located inside the mounting hole 602 and is slidably connected to the dielectric body 600, one end of the central protective cap 800 abuts against the second end of the button 700, and the other end of the central protective cap 800 protrudes from the abutting surface 102 through the mounting hole 602, the central protective cap 800 compresses the button 700 when the abutting surface 102 abuts against the circuit board, thereby enabling the central protective cap 800 to float and make conductive contact with the dielectric body 600. 2. When the contact surface 102 abuts against the circuit board, the grounding protection cap 300 slides into the metal housing 100 relative to the metal spring 200 and compresses the elastic element 400. The center protection cap 800 compresses the button 700 towards the mounting hole 602, so that both the grounding protection cap 300 and the center protection cap 800 can be elastically compressed when the contact surface 102 abuts against the circuit board. This gives both the grounding protection cap 300 and the center protection cap 800 good floating performance, so that the bent connector 10 has good axial tolerance performance. This enables the bent connector 10 to communicate and ground reliably, avoiding the problem of poor grounding effect of the bent connector 10. At the same time, it realizes the solderless interconnection between the bent connector 10 and the circuit board. 3. Since the grounding protection cap 300 can elastically abut against the circuit board through the elastic element 400, the grounding protection cap 300 can effectively abut against the circuit board when the abutting surface 102 abuts against the circuit board. In addition, the grounding protection cap 300 is arranged around the central protection cap 800, which avoids the problem of poor electromagnetic shielding of the connector, that is, improves the signal isolation of the connector. 4. Compared to the spring pin grounding method, the bent connector 10 described above conducts electricity to the circuit board through the grounding protection cap 300 and communicates electricity to the circuit board through the center protection cap 800. The center protection cap 800 is electrically connected to the adapter pin 500 through the button 700 to form a communication path. In addition, the metal spring 200 is insulated from the communication path through the dielectric body 600, which improves the impedance matching performance of the bent connector 10. It is especially suitable for high-frequency signal usage requirements in application scenarios with many channels and high frequencies.

[0060] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
