Description

Technical Field

[0001] The invention relates to the technical field of multi-channel radio frequency connectors, in particular to a fixing device for a multi-channel radio frequency connector. Background Art

[0002] In current electronic equipment, RF connectors are widely used in various communication equipment, test instruments and other fields. The fixing device of RF connector is an important component to ensure the normal operation of the connector.

[0003] Existing RF connector fixing devices usually adopt screw fixing or welding fixing. During the process of screw fixing, if the tightening force is too large when the screw is turned, it may cause damage to the connector or cause the screw to strip. When fixed by welding, when the connector needs to be replaced later, it cannot be replaced, and there is a problem of poor applicability. Therefore, it is necessary to set a fixing device for the existing RF connector. Summary of the invention

[0004] The object of the present invention is to provide a fixing device for a multi-channel radio frequency connector to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a fixing device for a multi-channel radio frequency connector, comprising a connector and a mounting seat, wherein two ends of the connector are respectively connected to racks, a plug-in interface is provided on one side of the mounting seat, and the connector is plugged into the interior of the mounting seat through two racks;

[0007] A limiting hole is respectively arranged at one end of the two racks, and a limiting assembly for limiting and cooperating with the limiting hole is installed inside the mounting seat, so as to limit and fix the racks and the connector;

[0008] The upper surface of the mounting seat is rotatably connected with a knob, the top and bottom of the knob are respectively wound with a winding rope, and the end of the winding rope away from the knob is connected to the limit assembly, and the winding rope is pulled by rotating the knob, so as to adjust the limit assembly;

[0009] The upper surface and the lower surface of the mounting seat are respectively mounted with heat-conducting shells for heat dissipation, and the heat-conducting shells are provided with a plurality of through slots for airflow and a plurality of heat-conducting blocks;

[0010] A first mounting groove is arranged inside the connector, a second mounting groove is arranged on the mounting seat, and a sealing ring for sealing is arranged between the first mounting groove and the second mounting groove.

[0011] The purpose of the above setting is that when the knob is turned, the knob will pull the winding rope. Since the winding rope is connected to the limit assembly, the limit assembly can be adjusted by pulling the winding rope. The connection or separation of the limit assembly and the limit hole is achieved through this adjustment, thereby facilitating the installation and disassembly of the connector. When air flows through the through groove, the heat conductive block can conduct the heat generated inside the mounting base to the heat conductive shell, and then take the heat away through the flow of air, thereby achieving the purpose of heat dissipation. The sealing ring can fill the gap between the first mounting groove and the second mounting groove to prevent dust from entering the interior of the mounting base through the gap, thereby playing a sealing role.

[0012] Furthermore, the limit assembly includes a mounting block, which is mounted on the inner wall of the mounting seat, and sliding cavities are respectively provided at both ends of the mounting block. A first spring is installed inside the sliding cavity, and a sliding rod is slidably connected to the inner wall of the sliding cavity. A limit rod is connected to the outer wall of the sliding rod, and the limit rod passes through the mounting block and is slidably connected, and one end of the limit rod is limitedly matched with the limit hole.

[0013] The purpose of the above-mentioned arrangement is that the first springs in the sliding cavities at both ends of the mounting block apply an outward force to the sliding rod. When the rack of the connector is inserted into the mounting seat, the limiting rod, under the tension of the first spring, has one end thereof cooperate with the limiting hole of the rack for limiting purpose, thereby fixing the connector. When the connector needs to be removed, the winding rope is pulled by the knob, and the winding rope drives the sliding rod. The sliding rod squeezes the first spring and slides toward the inside of the mounting block, thereby driving the limiting rod to be pulled out of the limiting hole to release the limit.

[0014] Furthermore, the limiting rod and the sliding rod are perpendicular to each other, the sliding rod passes through the top of the mounting block and the mounting seat and is slidably connected, and the top of the sliding rod is connected to the winding rope.

[0015] The purpose of the above arrangement is to make the limit rod and the sliding rod perpendicular to each other, so as to keep the two connected and stable during the movement.

[0016] Furthermore, two baffles are respectively installed on the outer walls of the two sliding rods, and two sliding grooves are formed on the top of the mounting seat to facilitate the movement of the sliding rods. The two baffles are respectively located on the upper and lower surfaces of the sliding grooves to close the sliding grooves and prevent dust from entering.

[0017] The purpose of the above arrangement is that when the sliding rod slides in the sliding groove, the baffle always covers the sliding groove to prevent dust from entering the interior of the mounting seat through the sliding groove.

[0018] Furthermore, a movable groove is provided in the middle of the mounting block, a sliding block is slidably connected to the movable groove, an airbag is connected to the top of the two sliding blocks, and the two baffles inside the mounting seat are used to squeeze the airbag during the sliding process.

[0019] The purpose of the above arrangement is that when the baffle plate is sliding, it will squeeze the airbag. When the airbag is squeezed, the internal gas flows to the inner side of the heat transfer shell groove through the air pipe.

[0020] Furthermore, an air pipe is connected to the outer wall of the air bag, and an end of the air pipe away from the air bag extends to the inner side of the heat-conducting shell groove;

[0021] One-way valves for switching on and off the air flow are respectively installed on the top of the knob and the air pipe.

[0022] The purpose of the above arrangement is that the one-way valves on the top of the knob and the airbag control the on-off of the airflow. When the airbag is squeezed, the one-way valve on the trachea opens, the gas passes through the trachea, and the one-way valve on the top of the knob is in a closed state;

[0023] When the airbag is squeezed and emptied and needs to be inflated later, the one-way valve on the air pipe is closed. After a certain amount of gas is filled in, the one-way valve on the top of the knob is closed to keep the gas inside the airbag closed.

[0024] Furthermore, the one-way valve includes a valve body, a valve core and a second spring. A sliding groove is provided on the inner wall of the valve body. The valve core is slidably connected to the sliding groove. A gap is left between the outer wall of the valve core and the inner wall of the valve body for air flow to pass through. The second spring is installed between the valve core and the second spring. In the initial state, due to the tension of the second spring, one end of the valve core closes one of the ports of the valve body.

[0025] The purpose of the above-mentioned setting is the composition structure and installation of the one-way valve.

[0026] Furthermore, a third spring for ejecting the rack and the mounting seat is installed on the inner wall of the mounting seat.

[0027] The purpose of the above arrangement is that when the limit assembly releases the limit on the rack, the tension of the third spring can push the rack and the connector to pop out, making disassembly easier. In the process of the rack being popped out, the guide assembly is also driven to operate to further dissipate heat from the heat-conducting shell.

[0028] Furthermore, a flow guide component for transmission cooperation with the rack is installed inside the mounting seat.

[0029] The purpose of the above arrangement is that the flow guide assembly is used to further dissipate heat from the heat-conducting shell and needs to be coordinated with the rack for transmission.

[0030] Furthermore, the guide assembly includes a large gear and a small gear, the large gear and the small gear are rotatably connected to the inside of the mounting seat through a rotating shaft, the number of gears of the small gear is half of the large gear, and the small gear and the large gear are meshed with each other;

[0031] The interior of the rotating shaft of the pinion gear is set to be hollow, the bottom end of the rotating shaft passes through the bottom of the mounting seat and extends to the outside, a fan blade is installed on the top outer wall of the pinion gear, a channel is connected between the outer wall of the pinion gear and the inner wall of the mounting seat, and the rotating shaft and the channel are connected to each other;

[0032] A pipe is arranged on the top of the mounting seat, and the pipe passes through the mounting seat and extends to the inside of the channel. An end of the pipe away from the channel is connected to a mounting plate, and the mounting plate is arranged on the outer wall of the heat-conducting shell. A plurality of air holes are opened on the outer wall of the mounting plate, and the plurality of air holes face the through grooves of the heat-conducting shell.

[0033] The purpose of the above arrangement is that when the rack acts on the large gear, the number of gears of the small gear is half of that of the large gear, and the small gear will rotate at a faster speed, thereby driving the fan blades to rotate at a faster speed. The interior of the small gear shaft is hollow, and the bottom end of the shaft passes through the bottom of the mounting seat and extends to the outside. The fan blades on the top outer wall rotate with the rotation of the small gear, guiding the airflow on the outside of the bottom of the mounting seat to the channel. The airflow passes from the channel through the pipe to the mounting plate, and then blows out from the air holes of the mounting plate toward the through grooves of the heat transfer shell. The blown airflow exchanges heat with the heat transfer shell, thereby cooling the heat transfer shell and enhancing the heat dissipation effect. At the same time, during the flow of air, the dust inside the heat transfer shell is blown and cleaned, thereby reducing the possibility of dust entering the mounting seat due to dust accumulation.

[0034] The present invention has the following beneficial effects:

[0035] (1) The present invention provides a limit assembly and a limit hole. When the knob is turned, the knob will pull the winding rope. Since the winding rope is connected to the limit assembly, the limit assembly can be adjusted by pulling the winding rope. The limit assembly and the limit hole are connected or separated by this adjustment, thereby facilitating the installation and removal of the connector, thereby solving the problem of poor applicability when the connector needs to be replaced later.

[0036] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] This embodiment is a fixing device for a multi-channel RF connector, such as Figure 1 - Fig.10 As shown, it includes a connector 1 and a mounting base 2, both ends of the connector 1 are connected to racks 5 respectively, one side of the mounting base 2 is provided with an insertion interface, and the connector 1 is plugged into the inside of the mounting base 2 through two racks 5;

[0052] A limiting hole 501 is respectively provided at one end of the two racks 5, and a limiting assembly 9 for limiting and cooperating with the limiting hole 501 is installed inside the mounting seat 2, so as to limit and fix the racks 5 and the connector 1;

[0053] The upper surface of the mounting seat 2 is rotatably connected with a knob 3, and a winding rope 4 is respectively wound around the top and bottom of the knob 3. The end of the winding rope 4 away from the knob 3 is connected to the limit assembly 9. The winding rope 4 is pulled by rotating the knob 3, so as to adjust the limit assembly 9.

[0054] The upper and lower surfaces of the mounting base 2 are respectively provided with a heat-conducting shell 7 for heat dissipation, and the heat-conducting shell 7 is provided with a plurality of through slots for airflow and a plurality of heat-conducting blocks;

[0055] A first mounting groove 101 is provided inside the connector 1 , a second mounting groove is provided on the mounting seat 2 , and a sealing ring 6 for sealing is provided between the first mounting groove 101 and the second mounting groove.

[0056] In this embodiment, the purpose of the above-mentioned setting is that when the knob 3 is turned, the knob 3 will pull the rope 4. Since the rope 4 is connected to the limit assembly 9, the limit assembly 9 can be adjusted by pulling the rope 4. The connection or separation of the limit assembly 9 and the limit hole 501 is achieved through this adjustment, thereby facilitating the installation and disassembly of the connector 1. When air flows through the through groove, the heat conductive block can conduct the heat generated inside the mounting base 2 to the heat conductive shell 7, and then take the heat away through the flow of air, thereby achieving the purpose of heat dissipation. The sealing ring 6 can fill the gap between the first mounting groove 101 and the second mounting groove to prevent dust from entering the interior of the mounting base 2 through the gap, thereby playing a sealing role.

[0057] As an implementation method, Figure 8 As shown, further:

[0058] The limiting assembly 9 includes a mounting block 901, which is mounted on the inner wall of the mounting seat 2. Sliding cavities are respectively provided at both ends of the mounting block 901. A first spring 905 is installed inside the sliding cavity. A sliding rod 903 is slidably connected to the inner wall of the sliding cavity. A limiting rod 902 is connected to the outer wall of the sliding rod 903. The limiting rod 902 passes through the mounting block 901 and is slidably connected. One end of the limiting rod 902 is limitedly matched with the limiting hole 501.

[0059] In this embodiment, the purpose of the above-mentioned arrangement is that the first springs 905 in the sliding cavities at both ends of the mounting block 901 apply an outward force to the sliding rod 903. When the rack 5 of the connector 1 is inserted into the mounting seat 2, the limiting rod 902 is under the tension of the first spring 905, and one end of the limiting rod 902 is limitedly matched with the limiting hole 501 of the rack 5, thereby fixing the connector 1. When the connector 1 needs to be disassembled, the winding rope 4 is pulled by the knob 3, and the winding rope 4 drives the sliding rod 903. The sliding rod 903 squeezes the first spring 905 and slides into the inside of the mounting block 901, thereby driving the limiting rod 902 to be pulled out of the limiting hole 501 to release the limit.

[0060] As an implementation method, Figure 8 As shown, further:

[0061] The limiting rod 902 and the sliding rod 903 are perpendicular to each other. The sliding rod 903 penetrates the mounting block 901 and the top of the mounting seat 2 and is slidably connected. The top of the sliding rod 903 is connected to the winding rope 4.

[0062] In this embodiment, the purpose of the above arrangement is to make the limiting rod 902 and the sliding rod 903 perpendicular to each other, so as to keep the two connected and stable during the movement.

[0063] As an implementation method, Figure 8 As shown, further:

[0064] Two baffles 904 are respectively installed on the outer walls of the two sliding rods 903. Two sliding grooves are formed on the top of the mounting base 2 to facilitate the movement of the sliding rods 903. The two baffles 904 are respectively located on the upper and lower surfaces of the sliding grooves to close the sliding grooves and prevent dust from entering.

[0065] In this embodiment, the purpose of the above arrangement is that when the sliding rod 903 slides in the sliding groove, the baffle 904 always covers the sliding groove to prevent dust from entering the interior of the mounting base 2 through the sliding groove.

[0066] As an implementation method, Figure 8 As shown, further:

[0067] A movable groove is provided in the middle of the mounting block 901, and a sliding block is slidably connected to the movable groove. The tops of the two sliding blocks are connected to the airbag 8. The two baffles 904 inside the mounting seat 2 are used to squeeze the airbag 8 during the sliding process.

[0068] In this embodiment, the purpose of the above arrangement is that when the baffle 904 is sliding, it will squeeze the airbag 8. When the airbag 8 is squeezed, the internal gas flows to the inner side of the through groove of the heat transfer shell 7 through the air pipe 10.

[0069] As an implementation method, Fig.10 As shown, further:

[0070] The outer wall of the airbag 8 is connected with an air pipe 10, and one end of the air pipe 10 away from the airbag 8 extends to the inner side of the through groove of the heat-conducting shell 7;

[0071] One-way valves for switching on and off the air flow are respectively installed on the top of the knob 3 and the air pipe 10 .

[0072] In this embodiment, the purpose of the above arrangement is that the one-way valves on the top of the knob 3 and the airbag 8 control the on-off of the airflow. When the airbag 8 is squeezed, the one-way valve on the trachea 10 opens, and the gas passes through the trachea 10, while the one-way valve on the top of the knob 3 is in a closed state.

[0073] When the airbag 8 is squeezed and emptied, and needs to be inflated later, the one-way valve on the trachea 10 is closed, and after a certain amount of gas is filled, the one-way valve on the top of the knob 3 is closed to keep the gas inside the airbag 8 closed.

[0074] As an implementation method, Fig.10 As shown, further:

[0075] The one-way valve includes a valve body, a valve core and a second spring. A sliding groove is provided on the inner wall of the valve body. The valve core is slidably connected to the sliding groove. A gap is left between the outer wall of the valve core and the inner wall of the valve body for air flow to pass through. The second spring is installed between the valve core and the second spring. In the initial state, due to the tension of the second spring, one end of the valve core closes one of the ports of the valve body.

[0076] In this embodiment, the purpose of the above arrangement is the composition structure and installation of the one-way valve.

[0077] As an implementation method, Fig.10 As shown, further:

[0078] A third spring 14 for ejecting the rack 5 and the mounting seat 2 is installed on the inner wall of the mounting seat 2 .

[0079] In this embodiment, the purpose of the above-mentioned setting is that when the limit assembly 9 releases the limit on the rack 5, the tension of the third spring 14 can push the rack 5 and the connector 1 to pop out, which is convenient for disassembly. In the process of the rack 5 being popped out, the guide assembly 11 is also driven to operate to further dissipate the heat of the heat conductive shell 7.

[0080] As an implementation method, Fig.10 As shown, further:

[0081] A flow guide assembly 11 for transmission cooperation with the rack 5 is installed inside the mounting seat 2 .

[0082] In this embodiment, the purpose of the above arrangement is that the flow guide component 11 is used to further dissipate heat for the heat-conducting shell 7 , and needs to be in transmission cooperation with the rack 5 .

[0083] As an implementation method, Figure 5 As shown, further:

[0084] The flow guide assembly 11 includes a large gear 1101 and a small gear 1102. The large gear 1101 and the small gear 1102 are rotatably connected to the inside of the mounting seat 2 through a rotating shaft. The number of gears of the small gear 1102 is half of that of the large gear 1101, and the small gear 1102 and the large gear 1101 are meshed with each other.

[0085] The interior of the rotating shaft of the pinion gear 1102 is set to be hollow, and the bottom end of the rotating shaft passes through the bottom of the mounting seat 2 and extends to the outside. A fan blade 1104 is installed on the top outer wall of the pinion gear 1102. A channel 1103 is connected between the outer wall of the pinion gear 1102 and the inner wall of the mounting seat 2, and the rotating shaft and the channel 1103 are connected to each other;

[0086] A pipe 12 is arranged on the top of the mounting seat 2, and the pipe 12 passes through the mounting seat 2 and extends to the inside of the channel 1103. The end of the pipe 12 away from the channel 1103 is connected to a mounting plate 13, and the mounting plate 13 is arranged on the outer wall of the heat-conducting shell 7. A plurality of air holes 1301 are opened on the outer wall of the mounting plate 13, and the plurality of air holes 1301 face the through grooves of the heat-conducting shell 7.

[0087] In this embodiment, the purpose of the above-mentioned setting is that when the rack 5 acts on the large gear 1101, the number of gears of the small gear 1102 is half of that of the large gear 1101, and the small gear 1102 will rotate at a faster speed, thereby driving the fan blades 1104 to rotate at a faster speed. The interior of the rotating shaft of the small gear 1102 is hollow, and the bottom end of the rotating shaft passes through the bottom of the mounting seat 2 and extends to the outside. The fan blades 1104 on the top outer wall thereof rotate as the small gear 1102 rotates, guiding the airflow on the outside of the bottom of the mounting seat 2 to the channel 1103. The airflow passes from the channel 1103 through the pipe 12 to the mounting plate 13, and then is blown out from the air holes 1301 of the mounting plate 13 toward the through grooves of the heat-conducting shell 7. The blown airflow exchanges heat with the heat-conducting shell 7, thereby cooling the heat-conducting shell 7 and enhancing the heat dissipation effect. At the same time, during the flow of the airflow, the dust inside the heat-conducting shell 7 is blown and cleaned, thereby reducing the possibility of dust entering the inside of the mounting seat 2 due to dust accumulation.

[0088] When in use, the first springs 905 in the sliding cavities at both ends of the mounting block 901 exert an outward force on the sliding rod 903. When the rack 5 of the connector 1 is inserted into the mounting seat 2, the limiting rod 902 is limitedly matched with the limiting hole 501 of the rack 5 at one end under the tension of the first spring 905, thereby fixing the connector 1. When the connector 1 needs to be disassembled, the winding rope 4 is pulled by the knob 3, and the winding rope 4 drives the sliding rod 903, and the sliding rod 903 squeezes the first spring 905 and moves toward the mounting block 901. The inner slide drives the limit rod 902 to be pulled out from the limit hole 501, and the limit is released. The limit rod 902 and the sliding rod 903 are perpendicular to each other, and the two are kept connected and stable during the movement. When the sliding rod 903 slides in the slide groove, the baffle 904 always covers the slide groove to prevent dust from entering the inside of the mounting seat 2 from the slide groove. When the baffle 904 slides, it squeezes the airbag 8. When the airbag 8 is squeezed, the internal gas flows to the inner side of the through groove of the heat transfer shell 7 through the air pipe 10;

[0089] The one-way valves on the top of the knob 3 and the airbag 8 control the on-off of the airflow. When the airbag 8 is squeezed, the one-way valve on the trachea 10 opens, the gas passes through the trachea 10, and the one-way valve on the top of the knob 3 is in a closed state;

[0090] When the airbag 8 is squeezed and emptied, if the airbag 8 needs to be inflated later, the one-way valve on the air pipe 10 is closed. After a certain amount of gas is filled, the one-way valve on the top of the knob 3 is closed to keep the gas inside the airbag 8 closed. The one-way valve includes a valve body, a valve core and a second spring. A sliding groove is provided on the inner wall of the valve body. The valve core is slidably connected to the sliding groove. A gap is left between the outer wall of the valve core and the inner wall of the valve body for airflow to pass through. The second spring is installed between the valve core and the second spring. In the initial state, due to the tension of the second spring, one end of the valve core closes one of the ports of the valve body.

[0091] When the limit assembly 9 releases the limit on the rack 5, the tension of the third spring 14 can push the rack 5 and the connector 1 to pop out, which is convenient for disassembly. During the process of the rack 5 being popped out, the flow guide assembly 11 is driven to operate to further dissipate the heat of the heat-conducting shell 7. The flow guide assembly 11 is used to further dissipate the heat of the heat-conducting shell 7 and needs to cooperate with the rack 5 in transmission.

[0092] When the rack 5 acts on the large gear 1101, the number of gears of the small gear 1102 is half of that of the large gear 1101, and the small gear 1102 will rotate at a faster speed, thereby driving the fan blades 1104 to rotate at a faster speed. The interior of the small gear 1102 shaft is hollow, and the bottom end of the shaft passes through the bottom of the mounting base 2 and extends to the outside. The fan blades 1104 on the top outer wall rotate with the rotation of the small gear 1102, and guide the airflow on the outside of the bottom of the mounting base 2 to the channel 1103. The airflow passes from the channel 1103 through the pipe 12 to the mounting plate 13, and then blows out from the air holes 1301 of the mounting plate 13 toward the through grooves of the heat transfer shell 7. The blown airflow exchanges heat with the heat transfer shell 7, thereby cooling the heat transfer shell 7 and enhancing the heat dissipation effect. At the same time, during the flow of the airflow, the dust inside the heat transfer shell 7 is blown and cleaned, thereby reducing the possibility of dust entering the mounting base 2 due to dust accumulation.
