Description

Technical Field

[0001] This utility model relates to the field of laser tubes, and in particular to a high-voltage shielded wiring device and a carbon dioxide laser tube. Background Technology

[0002] Current carbon dioxide laser tubes typically include a discharge tube, a water-cooling tube surrounding the discharge tube, a gas storage tube surrounding the water-cooling tube, cathode and anode electrodes inside the discharge tube, and output and reflection windows at both ends. The reflection window includes a reflecting mirror and a mirror cooling device, and the output window includes an output mirror and an output mirror cooling device. The discharge tube is filled with carbon dioxide gas and other auxiliary gases. When a high voltage is applied to the cathode and anode electrodes, a glow discharge is generated in the discharge tube. After reflection by the reflecting and output mirrors, a laser beam is formed, which exits from the output mirror. Due to their relatively high power, high energy conversion efficiency, and rich spectral lines, carbon dioxide laser tubes have been widely used in industry, military, medical, and scientific research.

[0003] In traditional carbon dioxide laser tubes, the cathode and anode inside the discharge tube are connected to an external power source via wires. To facilitate the wires extending out of the gas storage tube, a glass bead structure is usually installed on the gas storage tube. The wires pass through the glass bead structure to the outside of the gas storage tube, and then the core of the high-voltage wire is soldered to the wire at the glass bead structure. However, the installation method is cumbersome, requires special welding equipment, and the wire core is easily exposed after welding, forming a sharp point. During operation, high-voltage tip discharge can easily occur at the tip of the high-voltage wire. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by providing a high-voltage shielded wiring device and a carbon dioxide laser tube.

[0005] In a first aspect, this application provides a high-voltage shielded wiring device, including an insulating sleeve and a base. The base includes a stud and a conductor post connected to each other. The stud is detachably connected to the insulating sleeve. The conductor post is located inside the insulating sleeve. A mounting hole is provided at the end of the stud away from the insulating sleeve. The top of the mounting hole has a first inner conical surface.

[0006] It also includes an elastic clamping post for placement in the mounting hole, wherein the elastic clamping post is provided with a core clamping channel and a wire clamping channel that are interconnected, and the end of the elastic clamping post near the stud is provided with a first outer conical surface that matches the first inner conical surface;

[0007] It also includes a pressure cap, which is used to fix the elastic clamping post to the base.

[0008] The high-voltage shielded wiring device of this application has an insulating sleeve for connecting to a carbon dioxide laser tube, and a stud detachably connected to the insulating sleeve, thereby facilitating the installation and removal of the base. A mounting hole is provided at the end of the stud away from the insulating sleeve to accommodate an elastic clamp. The elastic clamp has a through-hole with interconnected core and wire clamping channels. When installing the high-voltage wire, the wire core is placed in the core channel, the high-voltage wire sheath is placed in the wire clamping channel, and then the elastic clamp is placed in the mounting hole of the stud. Furthermore, since the top of the mounting hole has a first inner conical surface, the end of the elastic clamp near the stud is provided with... The device has a first outer conical surface that matches the first inner conical surface. Through the cooperation of the first inner conical surface and the first outer conical surface, the elastic clamp can be quickly clamped in the mounting hole. Then, the pressure cap is used to fix the elastic clamp to the base, so that the elastic clamp is firmly fixed to the base. The present application can realize the quick clamping of high voltage wires on carbon dioxide laser tubes through the cooperation of the base, elastic clamp, and pressure cap. The operation is simple and does not require additional equipment. The wire core and the rubber sleeve of the high voltage wire are clamped and fixed by the elastic clamp. When the high voltage wire is subjected to external force, the rubber sleeve will be pulled by force, effectively preventing the wire core from breaking due to force.

[0009] Meanwhile, the current of the high-voltage line is transmitted to the conductor post of the base through the elastic clamp. The conductor post of the base is located inside the insulating sleeve. After the insulating sleeve is installed on the carbon dioxide laser tube, the electrodes of the discharge tube are powered through the conductor post. Compared with the traditional method of welding the high-voltage line to the glass bead of the carbon dioxide laser tube, the wire core is located inside the elastic clamp. The elastic clamp accommodates the wire core, avoiding the formation of a sharp point by the exposed wire core, thereby avoiding the generation of high-voltage sharp point discharge during operation.

[0010] Furthermore, the insulating sleeve prevents current from leaking to the outside, thus achieving high-voltage shielding after energization.

[0011] Preferably, it further includes a first strip-shaped slit spaced circumferentially along the side wall of the elastic clamping column, the first strip-shaped slit being connected to the core channel.

[0012] The first strip is connected to the core-sandwich channel, which facilitates the elastic deformation of the front end of the elastic clamping column. When the elastic clamping column is clamped, the front end sidewall of the elastic clamping column is squeezed by the first inner conical surface and then moves radially, thereby clamping the wire core located in the core-sandwich channel.

[0013] Preferably, the pressure cap includes a base plate and an annular plate arranged circumferentially along the base plate. The base plate is used to abut against the elastic clamping post, and the annular plate is threadedly connected to the end of the stud away from the insulating sleeve.

[0014] When fixing the high-voltage line, by rotating the pressure cap, the bottom plate of the pressure cap gradually squeezes the elastic clamp along the length of the stud, so that the elastic clamp enters the mounting hole until the elastic clamp is locked in the mounting hole.

[0015] Preferably, a tapered hole is provided in the middle of the base plate, and a second outer tapered surface matching the tapered hole is provided at the end of the elastic clamping post away from the stud.

[0016] During operation, the pressure cap is fitted onto the second outer conical surface of the elastic clamping column through the conical hole. Then, the pressure cap is rotated, and the base plate squeezes the second outer conical surface through the conical hole. As the elastic clamping column is squeezed, the conical hole and the second outer conical surface gradually lock together, thereby locking the base plate onto the elastic clamping column. Furthermore, when the pressure cap is used to fix the elastic clamping column, the pressure cap and the elastic clamping column also lock together, thus securing the elastic clamping column firmly.

[0017] Preferably, it further includes a second strip-shaped slit arranged circumferentially along the side wall of the elastic clamping column, the second strip-shaped slit being connected to the clamping channel, and the first strip-shaped slit and the second strip-shaped slit being arranged alternately.

[0018] By setting a second strip-shaped slit on the elastic clamp post, which is connected to the wire clamping channel, the rear end of the elastic clamp post can undergo elastic deformation. When clamping the elastic clamp post, the pressure cap is fitted onto the second outer conical surface of the elastic clamp post through the conical hole. Then, the pressure cap is rotated, and the base plate squeezes the second outer conical surface through the conical hole. During the squeezing process, the rear end sidewall of the elastic clamp post is squeezed by the sidewall of the conical hole and moves radially, thereby clamping the adhesive layer located in the wire clamping channel and fixing the high-voltage line.

[0019] Preferably, the insulating sleeve includes a first cylindrical body and a second cylindrical body that are interconnected, and the second cylindrical body is disposed on the side wall of the first cylindrical body;

[0020] The first cylinder is used to connect to the carbon dioxide laser tube, and one end of the stud is threaded into the second cylinder.

[0021] Preferably, the guide post is located inside the first cylinder or the second cylinder.

[0022] Preferably, it further includes a shielding sleeve installed on the insulating sleeve, wherein the base, the elastic clamping post and the pressure cap are all located inside the shielding sleeve.

[0023] By covering the base, elastic clamps, and pressure cap with a shielding sleeve, the base, elastic clamps, and pressure cap are further prevented from coming into contact with air or water, thereby preventing high-voltage discharge during operation.

[0024] Preferably, the shielding sleeve includes a first sleeve and a second sleeve arranged coaxially, the first sleeve is sleeved on the insulating sleeve, and the base, the elastic clamping post and the pressure cap are all located inside the first sleeve;

[0025] The second sleeve is used to accommodate the high-voltage line.

[0026] In a second aspect, this application provides a carbon dioxide laser tube, including a high-voltage shielded wiring device as described in this application, wherein the insulating sleeve is fitted onto one end of the gas storage tube, and the lead post is used to supply power to the electrodes of the discharge tube.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] 1. A high-voltage shielded wiring device of this application, wherein an insulating sleeve is used to connect to a carbon dioxide laser tube, and a stud is detachably connected to the insulating sleeve, thereby facilitating the installation and removal of the base. A mounting hole is provided at the end of the stud away from the insulating sleeve, for accommodating an elastic clamping post. The elastic clamping post has interconnected core channels and wire clamping channels running through its interior. When installing a high-voltage wire, the wire core of the high-voltage wire is placed in the core channel, the rubber sleeve of the high-voltage wire is placed in the wire clamping channel, and then the elastic clamping post is placed in the mounting hole of the stud. Furthermore, since the top of the mounting hole has a first inner conical surface, and the end of the elastic clamping post near the stud has a first outer conical surface that matches the first inner conical surface, the elastic clamping post can be quickly clamped into the mounting hole through the cooperation of the first inner and outer conical surfaces. Then, a pressure cap is used to fix the elastic clamping post to the base, making the elastic clamping post and the base firmly fixed. This application... The combination of the base, elastic clamps, and pressure caps enables rapid clamping of high-voltage wires onto the CO2 laser tube. The operation is simple, requiring no additional equipment. Both the wire core and sheath are secured by the elastic clamps. When the high-voltage wire is subjected to external force, the sheath is stretched, effectively preventing the wire core from breaking. Simultaneously, the current from the high-voltage wire is transmitted through the elastic clamps to the conductor posts on the base. These conductor posts are located inside the insulating sleeve. After the insulating sleeve is installed on the CO2 laser tube, the conductor posts supply power to the electrodes of the discharge tube. Compared to the traditional method of soldering the high-voltage wire to the glass beads of the CO2 laser tube, the wire core is located within the elastic clamps, which contain the wire core, preventing it from becoming exposed and forming sharp points, thus avoiding high-voltage discharge from the wire core during operation. Furthermore, the insulating sleeve prevents current leakage to the outside, achieving high-voltage shielding after energization.

[0029] 2. The carbon dioxide laser tube of this application provides power to the electrodes of the discharge tube by installing a high-voltage shielding wiring device on the gas storage tube. Compared with the traditional carbon dioxide laser tube which uses glass beads on the gas storage tube as connectors for high-voltage lines, the carbon dioxide laser tube of this application does not require the manufacture of glass beads, reducing the manufacturing difficulty of the gas storage tube and improving the production efficiency of the carbon dioxide laser tube. Furthermore, by using the high-voltage shielding wiring device to connect the high-voltage line, the risk of high-voltage tip discharge caused by the contact between the wire core and the air is effectively avoided, thus improving the safety performance of the carbon dioxide laser tube during use.

[0073] Example 1

[0074] like Figures 1-8 As shown, this embodiment discloses a high-voltage shielded wiring device, including an insulating sleeve 1 for connecting to a carbon dioxide laser tube, a base 2 mounted on the insulating sleeve 1, an elastic clamp 3 connected to the base 2, and a pressure cap 4 for fixing the elastic clamp 3.

[0075] The base 2 includes a stud 21 and a wire post 22 that are connected to each other. One end of the stud 21 is detachably connected to the insulating sleeve 1, and the wire post 22 is located inside the insulating sleeve 1.

[0076] The end of the stud 21 away from the insulating sleeve 1 is provided with a mounting hole 211, and the top of the mounting hole 211 has a first inner conical surface 212.

[0077] The elastic clamping post 3 is placed in the mounting hole 211, and the elastic clamping post 3 has a core channel 31 and a wire clamping channel 32 that are connected to each other. The end of the elastic clamping post 3 near the stud 21 is provided with a first outer conical surface 33 that matches the first inner conical surface 212.

[0078] The pressure cap 4 is used to fix the elastic clamp 3 onto the base 2.

[0079] The high-voltage shielded wiring device described in this embodiment, such as Figures 2-8As shown, the insulating sleeve 1 is connected to the carbon dioxide laser tube. The base 2 includes a stud 21 and a lead post 22. The stud 21 is detachably connected to the insulating sleeve 1, which facilitates the installation and removal of the base 2. The end of the stud 21 away from the insulating sleeve 1 is provided with a mounting hole 211. The mounting hole 211 is used to accommodate the elastic clamping post 3. The elastic clamping post 3 has a core channel 31 and a wire clamping channel 32 that are interconnected. When installing the high-voltage wire 6, the wire core 61 of the high-voltage wire 6 is placed in the core channel 61, the rubber sleeve 62 of the high-voltage wire 6 is placed in the wire clamping channel 32, and then the elastic clamping post 3 is placed in the mounting hole 211 of the stud 21. Furthermore, since the top of the mounting hole 211 has a first inner conical surface 212, the elastic clamping post 3 is close to the stud 21. One end of the column 21 is provided with a first outer conical surface 33 that matches the first inner conical surface 212. Through the cooperation of the first inner conical surface 212 and the first outer conical surface 33, the elastic clamping column 3 can be quickly clamped in the mounting hole 211. Then, the pressure cap 4 is used to fix the elastic clamping column 3 on the base 2, so that the elastic clamping column 3 and the base 2 are firmly fixed. Through the cooperation of the base 2, the elastic clamping column 3 and the pressure cap 4, the high voltage line 6 can be quickly clamped on the carbon dioxide laser tube. The operation is simple and does not require additional equipment. The wire core 61 and the rubber sleeve 62 of the high voltage line 6 are clamped and fixed by the elastic clamping column 3. When the high voltage line 6 is subjected to external force, the rubber sleeve 62 will be pulled by force, effectively preventing the wire core 61 from being broken by force.

[0080] Traditionally, the high-voltage wire 6 is soldered to the glass bead of the carbon dioxide laser tube. Because the wire core 61 is relatively thin, it is easily broken when subjected to external forces (such as pulling or bending). This application uses elastic clamping posts 3 to clamp the wire core 61 and the rubber sleeve 62 of the high-voltage wire 6. Figure 2 When the high-voltage line 6 is subjected to external force, the rubber sleeve 62 is pulled by the force, which can prevent the wire core 61 from being broken due to the force, and make the high-voltage line 6 more firmly connected to the carbon dioxide laser tube.

[0081] Meanwhile, the current of the high-voltage line 6 is transmitted to the conductor post 22 of the base 2 through the elastic clamp post 3. The conductor post 22 is located inside the insulating sleeve 1. After the insulating sleeve 1 is installed on the carbon dioxide laser tube, the electrodes of the discharge tube 8 are powered through the conductor post 22. Compared with the traditional method of welding the high-voltage line 6 to the glass bead of the carbon dioxide laser tube, the wire core 61 is located inside the elastic clamp post 3. The elastic clamp post 3 accommodates the wire core 61, which avoids the wire core 61 from being exposed and forming a sharp point, thereby avoiding the high-voltage sharp point discharge generated by the wire core 61 during operation.

[0082] Furthermore, the insulating sleeve 1 can prevent current leakage to the outside, thereby achieving high-voltage shielding after energization.

[0083] In an optional embodiment, the insulating sleeve 1 is made of ceramic, wherein the ceramic material has the characteristics of high voltage resistance, high temperature resistance and non-combustibility, which can effectively prevent high voltage leakage and also play a certain role in heat dissipation.

[0084] In an optional embodiment, the base 2 and the elastic clamping post 3 are made of uniformly conductive metal;

[0085] Furthermore, the base 2 and the elastic clamping post 3 are preferably made of brass.

[0086] In one or more implementations, such as Figure 4 As shown, it also includes a first strip slit 34 spaced circumferentially along the side wall of the elastic clamping column 3, and the first strip slit 34 is connected to the core channel 31.

[0087] By providing a first strip-shaped slit 34 at circumferential intervals on the side wall of the elastic clamping column 3, and the first strip-shaped slit 34 being connected to the core channel 31, it is possible for the front end of the elastic clamping column 3 to undergo elastic deformation. When clamping the elastic clamping column 3, the front side wall of the elastic clamping column 3 is compressed by the first inner conical surface 212 and the first outer conical surface 33 through the cooperation, causing radial movement of the front side wall of the elastic clamping column 3 after being squeezed by the first inner conical surface 212, thereby clamping the wire core 61 located in the core channel 31.

[0088] Wherein, the front end of the elastic clamping post 3 refers to the end of the elastic clamping post 3 that is close to the stud 21. In this application, the first strip slit 34 is provided at the front end of the elastic clamping post 3.

[0089] In optional implementations, such as Figure 7 As shown, the pressure cap 4 includes a base plate 41 and an annular plate 42 arranged circumferentially along the base plate 41, as... Figure 8 As shown, the base plate 41 is used to abut against the elastic clamping post 3, and the annular plate 42 is threadedly connected to the end of the stud 21 away from the insulating sleeve 1.

[0090] Since the annular plate 42 of the pressure cap 4 is threadedly connected to the stud 21, when fixing the high-voltage line 6, by rotating the pressure cap 4, the bottom plate 41 of the pressure cap 4 gradually squeezes the elastic clamping column 3 along the length direction of the stud 21, so that the elastic clamping column 3 enters the mounting hole 211 until the elastic clamping column 3 is locked in the mounting hole 211.

[0091] Furthermore, such as Figure 7 As shown, a tapered hole 43 is provided at the center of the base plate 41;

[0092] like Figure 5 As shown, the end of the elastic clamping post 3 away from the stud 21 is provided with a second outer conical surface 36 that matches the conical hole 41.

[0093] During the work, such as Figure 8As shown, the pressure cap 4 is fitted onto the second outer conical surface 36 of the elastic clamping column 3 through the conical hole 4. Then, the pressure cap 4 is rotated, and the base plate 41 presses the second outer conical surface 36 through the conical hole 43. As the elastic clamping column 3 is pressed, the conical hole 43 and the second outer conical surface 36 gradually lock together, thereby making the base plate 41 lock onto the elastic clamping column 3. Furthermore, when the pressure cap 4 is used to fix the elastic clamping column 3, the pressure cap 4 and the elastic clamping column 3 also lock together, thereby making the elastic clamping column 3 firmly fixed.

[0094] In one or more implementations, such as Figure 1 As shown, the insulating sleeve 1 includes a first cylindrical body 11 and a second cylindrical body 12 that are interconnected, and the second cylindrical body 12 is disposed on the side wall of the first cylindrical body 11;

[0095] The first cylinder 11 is used to connect to the carbon dioxide laser tube, and one end of the stud 21 is threaded into the second cylinder 12.

[0096] In optional implementations, such as Figure 2 As shown, the guide post 22 is located inside the first cylinder 11 or the second cylinder 12.

[0097] Example 2

[0098] like Figure 6 As shown, based on Embodiment 1, the high-voltage shielded wiring device described in this embodiment further includes a second strip-shaped slot 35 arranged circumferentially along the side wall of the elastic clamping column 3. The second strip-shaped slot 35 is connected to the clamping channel 32, and the first strip-shaped slot 34 and the second strip-shaped slot 35 are arranged alternately.

[0099] By setting a second strip slit 35 on the elastic clamping post 3, and the second strip slit 35 being connected to the wire clamping channel 32, it is possible for the rear end of the elastic clamping post 3 to undergo elastic deformation. When clamping the elastic clamping post 3, the pressure cap 4 is fitted onto the second outer conical surface 36 of the elastic clamping post 3 through the conical hole 4. Then, the pressure cap 4 is rotated, and the base plate 41 squeezes the second outer conical surface 36 through the conical hole 43. Thus, when the elastic clamping post 3 is squeezed, the rear end sidewall of the elastic clamping post 3 is squeezed by the sidewall of the conical hole 4 and then moves radially, thereby clamping the rubber sleeve 62 located in the wire clamping channel 32, thereby fixing the high voltage line 6.

[0100] Wherein, the rear end of the elastic clamping post 3 refers to the end of the elastic clamping post 3 away from the stud 21. In this application, the second strip slit 35 is provided in the rear end portion of the elastic clamping post 3.

[0101] Example 3

[0102] like Figure 1 , Figure 2As shown, based on Embodiment 1 or Embodiment 2, the high-voltage shielded wiring device described in this embodiment further includes a shielding sleeve 5 installed on the insulating sleeve 1, and the base 2, elastic clamping post 3 and pressure cap 4 are all located inside the shielding sleeve 5.

[0103] The base 2, elastic clamp 3, and pressure cap 4 are covered by the shielding sleeve 5 to prevent contact with external water and air, and further prevent high voltage discharge.

[0104] In optional implementations, such as Figure 2 As shown, the shielding sleeve 5 includes a first sleeve 51 and a second sleeve 52 arranged coaxially. The first sleeve 51 is sleeved on the insulating sleeve 1, and the base 2, the elastic clamping post 3 and the pressure cap 4 are all located inside the first sleeve 51.

[0105] The second sleeve 52 is used to accommodate the high-voltage line 6.

[0106] In an optional embodiment, the shielding sleeve 5 is made of silicone, wherein the first sleeve 51 is fitted over the outside of the second cylinder 12 of the insulating sleeve 1, and the inner diameter of the second sleeve 52 matches the outer diameter of the high-voltage line 6.

[0107] Example 4

[0108] like Figure 9 As shown, a carbon dioxide laser tube of this embodiment includes a high-voltage shielded wiring device as described in any one of Embodiments 1 to 3. An insulating sleeve 1 is sleeved on one end of the gas storage tube 7, and a lead post 22 is used to supply power to the electrodes of the discharge tube 8.

[0109] In this embodiment of the carbon dioxide laser tube, the high-voltage shielding wiring device described in this application is installed on the gas storage tube 7 to supply power to the electrodes of the discharge tube 8. Compared with the traditional carbon dioxide laser tube which uses glass beads on the gas storage tube 7 as connectors for the high-voltage line 6, the carbon dioxide laser tube in this embodiment does not require the manufacture of glass beads, reducing the manufacturing difficulty of the gas storage tube 7 and improving the production efficiency of the carbon dioxide laser tube. Furthermore, by using the high-voltage shielding wiring device to connect to the high-voltage line 6, the risk of high-voltage discharge caused by the contact of the core 61 of the high-voltage line 6 with the air is effectively avoided, thus improving the safety performance of the carbon dioxide laser tube during use.

[0110] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
