Description

Technical Field

[0001] This utility model relates to the field of matching technology, specifically to a micro-switch adjustment structure and matching device. Background Technology

[0002] A matching converter is an important RF and microwave device used to adjust the impedance of a circuit, ensuring efficient signal transmission and optimal device performance. It is widely used in antenna systems, RF amplifiers, microwave equipment, and test equipment to improve signal transmission efficiency and reduce reflections and losses through impedance matching. Matching converters typically have an interface and a microswitch. The microswitch connects the interface to the capacitors inside the matching converter, while the interface connects to external devices, such as RF amplifiers. The matching converter adjusts the input and output impedance of the RF amplifier to improve its efficiency and performance. During testing, the interface is usually connected to the electrical connector of the external device first, and then the microswitch is turned on to connect the external device to the capacitors. When not in use, the microswitch is turned off as a safety feature. In some special test scenarios, it is necessary to connect the electrical connector of the external device to the interface first, and then use the microswitch to electrically contact the connector. Before disassembling the external device, disconnect the microswitch from the connector, and then detach the connector from the interface.

[0003] However, existing matching devices still have shortcomings. For example, for electrical connectors of different diameters from external devices, since the microswitches cannot be moved, different models of microswitches need to be prepared to be compatible with the electrical connectors. This not only increases costs, but also requires frequent disassembly and replacement of microswitches, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a micro switch adjustment structure and matching device to solve the technical problem in the prior art that when the matching device is used with electrical connectors of different diameters from external equipment, different models of micro switches are required to be prepared to make electrical connections with the electrical connectors, which is costly and troublesome to disassemble and assemble.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, this utility model provides a micro-switch adjustment structure, comprising: A housing assembly, including a housing and an electrical connection disposed thereon; and A switch assembly includes a movable housing, a micro switch, and a tensioning element. The movable housing has a through-hole, and the tensioning element passes through the through-hole and is threaded to the housing. The size of the tensioning element is smaller than the length of the through-hole. The micro switch is located in the movable housing, and the electrical connection portion of the micro switch faces the electrical connector and can abut against the electrical connector when the electrical connector of an external device is connected to the electrical connector.

[0006] In some embodiments, the movable shell includes a cover and connecting ears on both sides of the cover. The connecting ears have elongated holes and are connected to the housing through the elastic member. A protective cavity is formed between the cover and the housing, and the micro switch is located in the protective cavity.

[0007] In some embodiments, the connecting ears on both sides of the cover are provided with a plurality of elongated holes.

[0008] In some embodiments, the micro switch is detachably connected to the wall of the protective cavity by screws.

[0009] In some embodiments, the cover has an avoidance notch, and the electrical connector is located in the avoidance notch.

[0010] In some embodiments, the housing assembly further includes a positioning protrusion disposed on the surface of the housing, the positioning protrusion engaging with the elongated hole, the positioning protrusion having a threaded hole and being threadedly connected to the fastener through the threaded hole.

[0011] In some embodiments, the tensioning element includes an adjustment knob, a screw, a lifting cap, and an elastic element. The adjustment knob is connected to the screw and threadedly connected to the screw hole. The lifting cap and the elastic element are both sleeved on the screw. The elastic element can accumulate elastic force when the screw is screwed into the screw hole and drive the lifting cap to abut against the connecting ear through the elastic force.

[0012] In some embodiments, the electrical connector includes a stud and a conductive element. The outer wall of the stud has an external thread and is detachably connected to an electrical connector of an external device through the external thread. The stud has a slot, and the conductive element is disposed in the slot and is used to electrically connect the electrical connector when the electrical connector of the external device is inserted into the slot.

[0013] In some embodiments, the movable shell is open on both sides along its direction of movement.

[0014] Secondly, this utility model also provides a matching device, including a capacitor and the micro switch adjustment structure described above. The capacitor is located inside the housing and is electrically connected to the micro switch and the electrical connector. When the electrical connector is connected to the electrical connector of an external device, the movable housing can drive the micro switch to electrically abut against the electrical connector of the external device when it moves.

[0015] Compared with existing technologies, the microswitch adjustment structure provided by this utility model features a microswitch connected to a movable shell. The movable shell can move relative to the housing to move the microswitch toward the electrical connector, thereby electrically abutting the connector when it connects to the electrical connector of an external device. After the movable shell is positioned, a tensioning device can be used to lock the movable shell onto the housing to fix the microswitch. For electrical connectors of different sizes, it is only necessary to first unlock the tensioning device, move the movable shell to make the microswitch electrically abut against the connector, and then tighten the tensioning device. Therefore, for electrical connectors of different sizes, only the movable shell needs to be moved to make the microswitch abut against the connector of different sizes, eliminating the need to prepare different models of microswitches, saving costs and simplifying operation.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] To address the technical problem in existing technologies where matching devices require different models of microswitches to be compatible with electrical connectors of different diameters, resulting in high costs and cumbersome assembly and disassembly, this invention provides a microswitch adjustment structure that enables the microswitch to be compatible with electrical connectors of different sizes by adjusting its position.

[0019] It should be noted that the micro switch adjustment structure described in this utility model is used in, but not limited to, matching devices. For ease of explanation, this utility model only uses the application of the micro switch adjustment structure in a matching device as an example. The principle of the micro switch adjustment structure applied in other types of equipment is essentially the same as that applied in a matching device, and will not be described in detail here.

[0020] Please see Figure 1 , Figure 1 This is a schematic diagram of a microswitch adjustment structure in one embodiment of the present invention. The microswitch adjustment structure 100 includes a housing assembly 1 and a switch assembly 2. The housing assembly 1 includes a housing 11 and an electrical connector 12 disposed on the housing 11. The switch assembly 2 includes a movable shell 21, a microswitch 22, and a tensioning member 23. The movable shell 21 has a through-hole 211. The tensioning member 23 passes through the through-hole 211 and is threaded to the housing 11. The size of the tensioning member 23 is smaller than the length of the through-hole 211. The microswitch 22 is disposed on the movable shell 21. The electrical connection portion 221 of the microswitch 22 faces the electrical connector 12 and can abut against the electrical connector when the electrical connector of an external device is connected to the electrical connector 12.

[0021] In this embodiment, the position of the micro switch 22 can be adjusted along the direction of the elongated hole 211 on the movable housing 21 through the cooperation of the tensioning element 23. This design allows the micro switch 22 to adapt to electrical connectors of different diameters, eliminating the need to prepare different models of micro switches for each size of electrical connector, greatly improving the compatibility of the matching device. Since the position of the micro switch 22 is adjustable, users do not need to frequently replace the micro switch to adapt to different electrical connectors, thus significantly reducing the replacement and maintenance costs of the equipment. The threaded connection design of the tensioning element 23 makes the position adjustment of the micro switch 22 very simple. Users can easily adjust the position of the micro switch 22 by simply rotating the tensioning element 23, achieving quick adaptation to different electrical connectors.

[0022] In one embodiment, please refer to Figure 1The movable housing 21 includes a cover 212 and connecting ears 213 on both sides of the cover 212. The connecting ears 213 have elongated holes 211 and are connected to the housing 11 by a fastener 23. A protective cavity 214 is formed between the cover 212 and the housing 11, and the micro switch 22 is located within the protective cavity 214. In this embodiment, the cover 212 provides a stable support structure for the micro switch 22, ensuring that it maintains a fixed position during operation, reducing malfunctions caused by external vibration or impact, and enhancing the reliability of the micro switch 22. The design of the protective cavity 214 can protect the micro switch 22 from external interference and damage, while providing a stable working environment. The design of the elongated holes 211 on the connecting ears 213 allows the movable housing 21 to move within a certain range along the direction of the elongated holes 211. By adjusting the fastener 23, the position of the micro switch 22 can be flexibly adjusted to accommodate electrical connectors of different diameters, enhancing the versatility and adaptability of the matching device.

[0023] In one embodiment, please refer to Figure 1 The connecting ears 213 on both sides of the housing 212 are provided with multiple elongated holes 211. In this embodiment, by providing multiple elongated holes 211 in each connecting ear 213, multiple possible installation positions for the micro switch 22 are provided, allowing the micro switch 22 to be adjusted more precisely to accommodate electrical connectors of different diameters and installation requirements. Furthermore, the multiple elongated holes 211 can be connected and locked using multiple fasteners 23, enhancing the stability of the movable housing 21 during installation.

[0024] In one embodiment, please refer to Figure 1 The micro switch 22 is detachably connected to the cavity wall of the protective cavity 214 by screws 222. In this embodiment, the micro switch 22 is detachably connected to the cavity wall of the protective cavity 214 by screws 222, which facilitates the installation and replacement of the micro switch 22, and also facilitates the maintenance and inspection of the micro switch 22.

[0025] In one embodiment, please refer to Figure 1 The cover 212 has a clearance notch 215, and the electrical connector 12 is located inside the clearance notch 215. In this embodiment, by opening the clearance notch 215 and placing the electrical connector 12 in the clearance notch 215, the electrical connector 12 can be located inside the cover 212, and the electrical connector 12 does not need to occupy additional space outside the cover 212, which helps to save space.

[0026] In one embodiment, please refer to Figure 2The housing assembly 1 also includes a positioning protrusion 13 on the surface of the housing 11. The positioning protrusion 13 engages with the elongated hole 211 and has a threaded hole, which is threadedly connected to the tightening member 23. In actual operation, the elongated hole 211 of the movable housing 21 can be first engaged with the positioning protrusion 13. The positioning protrusion 13 can restrict the movement of the movable housing 21 along a direction perpendicular to its sliding direction, so as to pre-position the movable housing 21. Then, the tightening members 23 are used one by one to connect the corresponding threaded holes to complete the fixation of the movable housing 21. Therefore, by setting the positioning protrusion 13, the installation of the movable housing 21 can be easily completed in this embodiment.

[0027] The tensioning element 23 is used to unlock or lock the movable housing 21. In one embodiment, please refer to... Figure 2 The tensioning component 23 includes an adjusting knob 231, a screw 232, a lifting cap 233, and an elastic element 234. The adjusting knob 231 is connected to the screw 232 and threadedly connected to a screw hole via the screw 232. Both the lifting cap 233 and the elastic element 234 are fitted onto the screw 232. The elastic element 234 accumulates elastic force when the screw 232 is screwed into the screw hole, and this elastic force drives the lifting cap 233 to abut against the connecting ear 213. In this embodiment, when the adjusting knob 231 rotates, it drives the screw 232 to rotate, causing the screw 232 to screw into the screw hole. During this process, the adjusting knob 231 presses against the lifting cap 233, moving it towards the connecting ear 213. The lifting cap 233 compresses the elastic element 234, accumulating elastic force. The lifting cap 233 applies an upward force to the adjusting knob 231 and the screw 232 through this elastic force, making it difficult for the screw 232 to rotate, thus ensuring a stable connection between the movable shell 21 and the shell 11.

[0028] In one embodiment, please refer to Figure 1 The electrical connector 12 includes a stud 121 and a conductive element 122. The outer wall of the stud 121 has an external thread 123, through which an electrical connector of an external device can be detachably connected. A slot 124 is provided inside the stud 121, and the conductive element 122 is disposed in the slot 124 and used to electrically connect the electrical connector when the electrical connector of the external device is inserted into the slot 124. This embodiment, through the above-described configuration, ensures a reliable electrical connection between the electrical connector 12 and the electrical connector of the external device, while providing a stable mechanical connection through the threaded connection.

[0029] In one embodiment, please refer to Figure 1 The movable housing 21 has openings on both sides along its direction of movement. This opening design facilitates the installation and adjustment of the micro switch 22, and also makes it easy to observe the position and status of the micro switch 22, ensuring that it can accurately abut the electrical connector, and also facilitates heat dissipation of the micro switch 22 during operation.

[0030] Secondly, please refer to Figure 3The present invention also provides a matching device 200, including a capacitor 3 and the micro switch adjustment structure 100 described above. The capacitor 3 is located inside the housing 11 and is electrically connected to the micro switch 22 and the electrical connector 12. When the electrical connector 12 is connected to the electrical connector of an external device, the movable housing 21 can drive the micro switch 22 to electrically abut against the electrical connector of the external device when it moves.

[0031] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below: The microswitch adjustment structure 100 provided by this utility model has a microswitch 22 connected to a movable shell 21. The movable shell 21 can move relative to the shell 11 to drive the microswitch 22 toward the electrical connector 12, so that it electrically abuts against the electrical connector when the electrical connector 12 is connected to the electrical connector of an external device. After the movable shell 21 is in a determined position, a tensioning member 23 can be used to lock the movable shell 21 onto the shell 11 to fix the microswitch 22. For electrical connectors of different sizes, it is only necessary to first unlock the tensioning member 23, move the movable shell 21 to drive the microswitch 22 to electrically abut against the electrical connector, and then lock the tensioning member 23. It can be seen that for electrical connectors of different sizes, only the movable shell 21 needs to be moved to make the microswitch 22 abut against the electrical connector of different sizes, eliminating the need to prepare different models of microswitches, saving costs and simplifying operation.

[0032] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
