Description

[0042] This embodiment provides a switch connector. Figure 1 It is a schematic diagram of the overall structure of the switch connector of this embodiment. Refer to Figure 1 This embodiment's switch connector includes an insulating body 10, multiple groups of metal terminals 20, multiple signal isolation members 30, and a shielding housing 40. Refer to Figure 2 The insulating body 10 is provided with a plurality of insertion holes 11 and a plurality of terminal grooves 12, and each terminal groove 12 is provided with a group of metal terminals 20. Refer to Figure 1 The shielding housing 40 covers the outside of the insulating body 10 and is provided with a plurality of fixing parts 42 that avoid the terminal grooves 12, ensuring structural stability and effectively shielding electromagnetic interference to ensure signal quality.

[0043] Refer to Figure 2 and Figure 3 The insertion holes 11 and the terminal grooves 12 correspond to each other one by one and are interconnected. Refer to Figure 3 Each group of metal terminals 20 includes a movable terminal 21 and a static terminal 22, and the ends of the movable terminal 21 and the static terminal 22 overlap each other. When the probe of the test device passes through the insertion hole 11 and presses the movable terminal 21, the end of the movable terminal 21 separates from the end of the static terminal 22, thereby disconnecting the RF line 50 connected by the metal terminal 20 for device detection.

[0044] Refer to Figure 2 The multiple terminal grooves 12 are not interconnected with each other. Each group of metal terminals 20 is respectively connected to different RF lines 50 to achieve multi-channel connection, reduce the number of connectors and the complexity of installation, and improve the convenience and efficiency of testing. This embodiment's switch connector also includes multiple signal isolation members 30. Refer to Figure 2 Each group of metal terminals 20 is arranged between two signal isolation members 30. The signal isolation members 30 can eliminate and reduce the signal interference between the lines connected by each group of metal terminals 20 to ensure the accuracy of testing.

[0045] Figure 6 It is a schematic diagram of the insulating body 10 of this embodiment. Refer to Figure 6, the insulating body 10 is in the shape of a cuboid as a whole, and a plurality of insertion holes 11 and a plurality of terminal grooves 12 are arranged along the length direction of the insulating body 10. Refer to Figure 2 and Figure 3 , the insertion holes 11 are longitudinally arranged in the insulating body 10, that is, along the height direction of the insulating body 10. Refer to Figure 3 、 Figure 6 and Figure 7 , the terminal grooves 12 are transversely through, that is, through along the width direction of the insulating body 10. Refer to Figure 2 and Figure 3 , the insertion holes 11 are arranged directly above the terminal grooves 12 to guide the probes of the testing equipment into the terminal grooves 12. A plurality of positioning bosses 15 are also arranged on the upper surface of the insulating body 10, and the insertion holes 11 are located within the positioning bosses 15 and continue to extend downward to the terminal grooves 12. Refer to Figure 2 and Figure 3 , the insertion holes 11 are through within the positioning bosses 15, and the insertion holes 11 are in a funnel shape. The top end of the insertion hole 11 is the end with a larger diameter, and the funnel shape design helps to guide the probes of the testing equipment to quickly and accurately extend into the insertion holes 11.

[0046] Refer to Figure 2 , a set of metal terminals 20 are arranged in each terminal groove 12. Refer to Figure 3 and Figure 8 , one end where the moving terminal 21 and the static terminal 22 overlap is located within the terminal groove 12, and the other ends extend out from the two side openings of the terminal groove 12 respectively. Refer to Figures 8 - 10 , the moving terminal 21 includes an elastic arm 211 and a first welding part 212 which are connected to each other, and a contact part 213 which contacts the static terminal 22 is formed at one end of the elastic arm 211. The static terminal 22 includes an overlapping part 221 and a second welding part 222 which are connected to each other. Refer to Figure 3 , the elastic arm 211 and the overlapping part 221 are located within the terminal groove 12, and the overlapping part 221 overlaps above the contact part 213. The elastic arm 211 is located below the insertion hole 11, and the overlapping part 221 avoids the insertion hole 11 and is located on one side of the insertion hole 11 to prevent the probes of the testing equipment from accidentally touching the overlapping part 221. When the probe extends into the insertion hole 11, the contact part 213 is separated from the overlapping part 221 by pressing the elastic arm 211. When the probe is removed, the elastic arm 211 resets, and the contact part 213 reconnects with the overlapping part 221.

[0047] Refer to Figure 2 and Figure 9, the elastic arm 211 is arranged in a check mark shape, extending obliquely downward from one end close to the first welding part 212 and then bending obliquely upward. The middle bent part of the elastic arm 211 can provide an elastic function. The first welding part 212 is connected to the shorter end of the elastic arm 211, and the contact part 213 is located at the end of the longer end of the elastic arm 211. When pressing the end of the elastic arm 211 where the contact part 213 is located, the middle bent part can withstand a certain bending and restoring force, thereby realizing the separation and latching between the contact part 213 and the latching part 221.

[0048] Refer to Figure 9 , the contact part 213 extends obliquely upward along the elastic arm 211 to a position higher than or equal to the latching part 221, then bends obliquely downward and continues to extend to a position lower than the latching part 221. Such a structure enables the contact part 213 to extend below the latching part 221 and be in close contact with the latching part 221 when assembling the moving terminal 21 and the static terminal 22. The bent part of the contact part 213 can ensure stable contact between the contact part 213 and the latching part 221. The part where the contact part 213 extends obliquely downward facilitates the contact part 213 to extend below the latching part 221 during installation. A dividing groove 214 that divides the contact part 213 into two parts is also provided in the middle of the contact part 213. Dividing the contact part 213 into two parts helps to disperse the contact pressure to reduce the wear of a single contact point, thereby extending the service life of the structure.

[0049] Refer to Figure 10 , two top corners of the latching part 221 close to the moving terminal 21 are folded downward to form two limiting corners 223, and the contact part 213 is located between the two limiting corners 223. The limiting corners 223 can ensure the correct alignment between the contact part 213 and the latching part 221 during the assembly process, and effectively increase the contact area to achieve efficient electrical connection.

[0050] Refer to Figure 9 , one end of the elastic arm 211 connected to the first welding part 212 extends to both sides to form a first latching part 215. Refer to Figure 10 , one end of the latching part 221 connected to the second welding part 222 extends to both sides to form a second latching part 224. Refer to Figure 3 and Figure 11 , latching grooves 16 are respectively arranged above the openings on both sides of the terminal groove 12. The size of the latching groove 121 is larger than the size of the terminal groove 12, and is larger than or equal to the sizes of the first latching part 215 and the second latching part 224. The first latching part 215 and the second latching part 224 are respectively latched in the corresponding latching grooves 121 to limit and fix the moving terminal 21 and the static terminal 22.

[0051] Refer to Figure 3 , the first welding part 212 and the second welding part 222 are respectively located outside the terminal groove 12. Refer to Figure 7, welding grooves 14 are respectively arranged on both sides of the bottom of the insulating body 10, and the welding grooves 14 on both sides are longitudinally communicated with the corresponding terminal grooves 12 respectively. The welding groove 14 has a lateral opening, and the opening extends upward to communicate with the lateral opening of the terminal groove 12, so as to realize longitudinal communication. Refer to Figure 3 , the first welding part 212 and the second welding part 222 are respectively located at the communication part of the welding groove 14 and the terminal groove 12. At the same time, the bottoms of the first welding part 212 and the second welding part 222 are respectively bent inward and extended into the corresponding welding groove 14, so as to be welded and connected with the radio frequency line 50 on the circuit board.

[0052] When assembling the metal terminal 20, the moving terminal 21 and the static terminal 22 are respectively inserted into the terminal groove 12 from the two side openings of the terminal groove 12. The first clamping part 215 and the second clamping part 224 respectively extend into the corresponding clamping grooves 16, and the moving terminal 21 and the static terminal 22 are respectively limited and fixed in the terminal groove 12. At the same time, the first welding part 212 and the second welding part 222 are located in the corresponding welding grooves 14. The metal terminal 20 of this embodiment has a simple structure and is easy to disassemble and install, effectively improving the reliability of the overall structure and the production efficiency.

[0053] After each group of metal terminals 20 is connected to the radio frequency line 50, the signal isolation part 30 can effectively reduce the crosstalk between adjacent lines and ensure the signal quality of each line. Refer to Figure 4 , the signal isolation part 30 of this embodiment is of a T-shaped structure. Refer to Figure 2 , the insulating body 10 is provided with a T-shaped installation groove 13 matching the signal isolation part 30, and the signal isolation part 30 is installed in the T-shaped installation groove 13. The height of the signal isolation part 30 is equal to or greater than the thickness of the insulating body 10, that is, the bottom of the signal isolation part 30 leaks out from the T-shaped installation groove 13, which is convenient for connecting with the grounding layer of the circuit board. Refer to Figure 4 , an arc groove is further arranged at the bottom of the signal isolation part 30, which effectively increases the contact area between the signal isolation part 30 and the solder paste and improves the connection stability of the signal isolation part 30.

[0054] The signal isolation part 30 is made of a conductive material. The signal isolation part 30 of this embodiment is a metal isolation part or an absorbing material isolation part. The absorbing material is thinner, and the signal isolation part 30 made of the absorbing material occupies less space, which is helpful for the miniaturization design of the overall structure. Moreover, the absorbing material can absorb electromagnetic waves, thereby reducing the reflection and diffraction of electromagnetic waves in space, reducing electromagnetic interference, and improving the stability and reliability of the overall structure. Optionally, the signal isolation part 30 can also be made of a conductive material such as metallized plastic or a conductive coating according to specific circumstances.

[0055] Refer to Figure 1, a shielding housing 40 is provided outside the insulating body 10 to further shield external electromagnetic interference. Refer to Figure 5 , the shielding housing 40 further includes a covering portion 41 and a connector 43, and the connector 43 is coaxially arranged with the insertion hole 11 on the surface of the covering portion 41. Refer to Figure 5 , the covering portion 41 covers the upper surface of the insulating body 10 to shield external electromagnetic interference. The covering portion 41 is crimped with the signal isolation member 30 in the T-shaped mounting groove 13, which limits and fixes the signal isolation member 30 while effectively improving the overall shielding effect and ensuring signal quality. Refer to Figure 2 and Figure 5 , the connector 43 is provided with a protrusion 431 that imitates the positioning boss 15, and the protrusion 431 wraps around the outside of the positioning boss 15, which helps to improve the shielding effect. Refer to Figure 2 、 Figure 3 and Figure 5 , a jack 432 communicating with the insertion hole 11 is opened at the top end of the protrusion 431, and the size of the jack 432 is the same as that of the insertion hole 11, ensuring that the probe of the test device can smoothly extend into the insertion hole 11.

[0056] Refer to Figure 5 , the fixing portions 42 are symmetrically arranged on both sides of the covering portion 41, and there is an interval between the plurality of fixing portions 42. Refer to Figure 1 , the fixing portions 42 are attached to both sides of the insulating body 10 and are located on one side of the terminal groove 12. The bottom of the fixing portion 42 is bent inward to wrap and fix the insulating body 10. The plurality of fixing portions 42 are arranged at intervals to avoid the metal terminals 20, so as not to affect the connection between the metal terminals 20 and the radio frequency line 50. Refer to Figure 6 and Figure 7 , a plurality of fixing grooves 17 are respectively provided on both sides of the insulating body 10. The fixing portions 42 are arranged in the fixing grooves 17 and are flush with the surface of the uncovered insulating body 10, making the overall structure relatively flat and ensuring the structural stability and spatial planning during installation.

[0057] In the switch connector of this embodiment, multiple groups of metal terminals are arranged in the insulating body to connect multiple radio frequency lines at the same time. Through the multi-channel design, the number of switch connectors and the complexity of connections can be reduced, effectively improving the installation efficiency of the switch connector and reducing the overall cost at the same time. Moreover, a signal isolation member is provided between each group of metal terminals to reduce or eliminate the interference between adjacent radio frequency lines through the signal isolation member, ensuring the purity of the signal and the accuracy of the test.

[0058] This embodiment also provides a wireless communication module, which includes a radio frequency line 50 and the switch connector in the above embodiment. The multiple groups of metal terminals 20 of the switch connector are respectively electrically connected to the multiple radio frequency lines 50 in one-to-one correspondence, and each radio frequency line 50 can be independently controlled and tested. Refer toFigure 12 , the radio frequency line 50 includes a radio frequency circuit 54 and an antenna circuit 52. The radio frequency circuit 51 is responsible for the generation, processing, and control of signals, while the antenna circuit 52 is responsible for the transmission between the signal and the antenna. The moving terminal 21 is electrically connected to the radio frequency circuit 51, and the stationary terminal 22 is electrically connected to the antenna circuit 52. When the probe of the test device presses the moving terminal 21, the moving terminal 21 separates from the stationary terminal 22, and thus the radio frequency circuit 51 is disconnected from the antenna circuit 52. When the probe is removed, the moving terminal 21 reconnects with the stationary terminal 22, and the radio frequency circuit 51 and the antenna circuit 52 resume connection. The signal isolation member 30 and the shielding housing 40 are respectively electrically connected to the ground layer on the circuit board. The shielding housing 40 and the signal isolation member 30 can reduce electromagnetic interference, improve signal quality, and ensure the accuracy of test results.

[0059] In the switch connector provided in the wireless communication module of this embodiment, multiple groups of metal terminals are provided, which can connect multiple radio frequency lines to simplify the wiring of the radio frequency lines and support high-density wiring. A signal isolation member is also provided in the switch connector to reduce crosstalk and improve signal integrity. Moreover, the switch connector of the wireless communication module of this embodiment can integrate multiple signal paths, significantly reducing the installation time and labor costs.

[0060] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
