Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a connector for new energy vehicles. Background Technology

[0002] New energy vehicles use connectors to transmit signals and electrical energy. During maintenance, some connectors are disconnected for safety reasons. To facilitate the disconnection of the male and female connectors, some connectors on the market have hooks between the male and female ends for secure fastening. Once the hooks are released, the male and female ends can be separated.

[0003] For example, Chinese patent application number CN201820998420 discloses a heavy-duty connector, specifically stating that "a hook is rotatably provided on the outer side wall of a first mounting shell, and a locking post is provided on the outer side wall of a second mounting shell. Rotating the hook allows it to engage with the locking post, thereby fixing the first and second mounting shells together. A mounting block is fixedly provided on the outer side wall of the first mounting shell, and a rotating shaft is provided on the side wall of the mounting block away from the first mounting shell. The hook is connected to the rotating shaft and can rotate about the axis of the rotating shaft." This design uses a hook for connection, but in practice, it has been found that the hook and rotating shaft wear and loosen after repeated disassembly and assembly, making the connector connection prone to loosening.

[0004] For example, Chinese patent application number CN201520355468.2 describes a novel heavy-duty connector module, comprising: a hexahedral upper housing with an opening on one side, and a lower housing covering the opening of the upper housing. A protrusion is provided on the side of the upper housing, and a corresponding hook is provided on the side of the lower housing. The upper and lower housings are connected by engaging the protrusion with the hook. However, these hooks and protrusions may wear and loosen after repeated disassembly and assembly, making the connector connection prone to loosening. Summary of the Invention

[0029] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0030] Please refer to Figures 1 to 11 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a connector for new energy vehicles.

[0031] When the male head 10 and the female head 30 are locked, the locking pin 311 is inserted into the locking hole 414 along the entrance of the locking hole 414, and the first slide rail 423 on the limiting member 420 extends into the first limiting groove 111. This design can avoid loosening caused by wear, and make the connection between the male head 10 and the female head 30 more secure.

[0032] Please refer to Figure 1-4 As shown, this application provides a connector for a new energy vehicle, including a male connector 10, a female connector 30, and a locking device 40. The male connector 10 is pluggably mounted on the female connector 30, and the locking device 40 can lock the male connector 10 and the female connector 30 together. The male connector 10 includes a first housing 110. The first housing 110 has a first limiting groove 111 and a first positioning part 112. The female connector 30 includes a second housing 310. The second housing 310 is provided with a locking post 311.

[0033] Please refer to Figure 5-6As shown, the locking device 40 includes a locking frame 410 and a limiting member 420; wherein, the limiting member 420 has an elastic hook 421 and a first slide rail 423; the locking frame 410 has a first sliding groove 411, a first positioning hole 412, a first limiting part 413, and a locking hole 414; the limiting member 420 is slidably disposed on the locking frame 410; the first slide rail 423 slides in the first sliding groove 411 and can extend into the first limiting groove 111; the first positioning part 112 passes through the first positioning hole 412, and the elastic hook 421 can hook the first limiting part 413; the locking frame 410 is swayably disposed on the first housing 110; the locking pin 311 can be engaged in the locking hole 414 along the inlet on the locking hole 414.

The male connector 10 is inserted into the female connector 30, and the male connector 10 and the female connector 30 are fastened together by a locking device 40 to prevent them from loosening. The locking bracket 410 can swing up and down on the first housing 110. When the male connector 10 is inserted into the female connector 30, the locking bracket 410 swings, causing the locking pin 311 to be inserted into the locking hole 414 through the inlet, and the first positioning part 112 passes through the first positioning hole 412; then the limiting member 420 is pushed, and the first slide rail 423 slides in the first slide groove 411, with part of the first slide rail 423 extending into the first limiting groove 111, and the elastic hook 421 hooks into the first limiting part 413, so that the limiting member 420 will not loosen. At this point, if it is necessary to unlock the limiting member 420, push the limiting member 420 with your finger to release the elastic hook 421 from the first limiting part 413, and the first slide rail 423 will exit from the first limiting groove 111. This allows the locking frame 410 to swing, and the locking pin 311 to exit from the locking hole 414. It can be seen that this locking structure is simple, has good stability, and is easy to operate. The locking pin 311 passes through the locking hole 414, and the limiting member 420 is provided to prevent the locking frame 410 from loosening. This structure has good stability and there is no problem of loosening.

Sub-module 340; a plug-in interface 312 is formed on the second housing 310; a second mounting groove 313 is formed on the back of the second housing 310; a second insulating module 330 is fastened into the second mounting groove 313; a second terminal module 340 is inserted into the second insulating module 330 and extends into the plug-in interface 312; a plug connector 114 is inserted into the plug-in interface 312; the second terminal module 340 is inserted into the first terminal module 230, and the first terminal module 230 and the second terminal module 340 are connected.

[0035] The first outer shell 110, the first insulating module 220, the second outer shell 310, and the second insulating module 330 are manufactured using injection molding. The first terminal module 230 and the second terminal module 340 are made of copper alloy or copper and are conductive. When assembling the male connector 10, the first insulating module 220 is fastened into the first mounting groove 113, and the first terminal module 230 is inserted into the first terminal module hole 201 on the first insulating module 220, thus securing the first insulating module 220 within the first terminal module hole 201. When assembling the female connector 30, the second insulating module 330 is fastened into the second mounting groove 313, and the second terminal module 340 is inserted into the second terminal module hole 340 on the second insulating module 330, thus securing the second insulating module 330 within the second terminal module hole 340. Therefore, the assembly of both the male connector 10 and the female connector 30 is very simple and convenient. When the male connector 10 and the female connector 30 are connected, the second terminal module 340 is inserted into the first terminal module 230, and the male connector 10 and the female connector 30 are connected.

[0036] Please refer to Figure 2-3As shown, the first insulating module 220 includes a first insulating base 210 and a second insulating base 220; the first insulating base 210 has a first fastening part 211 and a first boss 212 formed thereon; the second insulating base 220 is provided with a first fastening hole 221, a first fitting groove 222, and a second fastening part 223 with an inclined surface; the wall plate of the connector 114 has a first fastening opening 115 formed thereon; the first boss 212 is inserted into the first fitting groove 222, and the first fastening part 211 is fastened into the first fastening hole 221; the first insulating base 210 and the second insulating base 220 are embedded in the first mounting groove 113, and the second fastening part 223 is engaged in the first fastening opening 115; a first terminal module hole 201 is formed through the first insulating base 210 and the second insulating base 220, and the first terminal module 230 is engaged in the first terminal module hole 201. The assembly steps of the first insulating module 220 are as follows: the first insulating base 210 and the second insulating base 220 are fastened together; the first boss 212 is inserted into the first fitting groove 222; and the first fastening part 211 is fastened into the first fastening hole 221, so that the first insulating base 210 and the second insulating base 220 are assembled into a whole. The first insulating base 210 and the second insulating base 220 are inserted into the first mounting groove 113, so that the second fastening part 223 is engaged in the first fastening opening 115. In this way, the first insulating base 210 and the second insulating base 220 can be installed into the first outer shell 110. It can be seen that the assembly of the first insulating base 210 and the second insulating base 220 is very simple. During production, the first wire core is riveted to the first terminal module 230, and then the first terminal module 230 is inserted into the first terminal module hole 201. Next, the first insulating base 210 and the second insulating base 220 are embedded into the first mounting groove 113. Therefore, the assembly of the male connector 10 is very convenient. A second sealing ring 127 is also fitted on the first outer shell 110. The second sealing ring 127 can improve the sealing degree and waterproof capability after the male and female connectors are connected.

[0037] The second insulating module 330 includes a third insulating base 331, on which a third fastening part 332 is provided; a second fastening hole 314 is provided on the wall panel of the second mounting groove 313, the third insulating base 331 is embedded in the second mounting groove 313, and the third fastening part 332 is fastened to the second fastening hole 314; a second terminal module 340 hole is formed through the second outer shell 310 and the third insulating base 331, and the second terminal module 340 is inserted into the second terminal module 340 hole. The third insulating base 331 is manufactured by injection molding. During assembly, the third insulating base 331 is embedded in the second mounting groove 313, so that the third fastening part 332 is fastened to the second fastening hole 314, thus fixing the third insulating base 331 in the second mounting groove 313. The second wire core is riveted to the second terminal module 340, and then the second terminal module 340 is inserted into the second terminal module 340 hole. As can be seen, the assembly of the female connector 30 is also very convenient. The first outer shell 110, the first insulation module 220, the first terminal module 230, the second outer shell 310, the first insulation module 220, and the second terminal module 340 are assembled by snap-fit ​​and locking, which is simple in structure, convenient in assembly, and efficient in assembly.

[0038] Please refer to Figure 9As shown, the first terminal module 230 includes a first plug-in cylinder 231 and a first mounting cylinder 235. A first slit 232 is longitudinally arranged on the first plug-in cylinder 231. A first wire clamping piece 233 is formed at the tail of the first plug-in cylinder 231, and a first mounting piece 234 is formed by tearing in the middle of the first plug-in cylinder 231. A second slit 236 is longitudinally arranged on the first mounting cylinder 235, and the cylinder walls on both sides of the second slit 236 are interlocked by first meshing teeth 237. A first mounting hole 238 is provided at the tail of the first mounting cylinder 235. A first locking piece 239 is formed by tearing in the head of the first mounting cylinder 235. The first wire clamping piece 233 is riveted onto the first wire core. The first plug-in cylinder 231 is inserted into the first mounting cylinder 235, and the first mounting piece 234 protrudes from the first mounting hole 238. The first locking piece 239 is engaged in the first terminal module hole 201. The first plug-in cylinder 231 and the first mounting cylinder 235 are manufactured using a stamping process. The first wire core is inserted into the first connector sleeve 231. The first slit 232 allows the first connector sleeve 231 to be slightly expanded, and the first wire core is riveted together by the first pressure plate 233. When the first connector sleeve 231 is inserted into the first mounting sleeve 235, the first mounting plate 234 passes through the first mounting hole 238, and the first mounting hole 238 bends and presses against the outer wall of the first mounting sleeve 235, thus fixing the first connector sleeve 231 inside the first mounting sleeve 235. The sleeve walls on both sides of the second slit 236 of the first mounting sleeve 235 interlock with each other, so that the first mounting sleeve 235 will not be stretched open when the first connector sleeve 231 is inserted into it. Therefore, the assembly between the first connector sleeve 231 and the first mounting sleeve 235 is very firm and simple. The first locking piece 239 is elastic. The first terminal module hole 201 has a larger central size and smaller ends. After the first terminal module 230 is inserted into the first terminal module hole 201, it is firmly fixed inside the hole by the first locking piece 239 and will not loosen. When the first terminal module 230 is inserted into the first terminal module hole 201, it is pressed more tightly by the hole wall as the insertion depth increases, allowing the first wire core to be pressed more firmly by the first connector tube 231, resulting in better contact quality. The walls on both sides of the second slit 236 on the first mounting tube 235 interlock, facilitating the first mounting tube 235 to wrap around the first connector tube 231.

[0039] Please refer to Figure 9As shown, the second terminal module 340 includes a first pin 341 and a second mounting cylinder 346. A third slit 342 is longitudinally arranged on the first pin 341. A second pressure plate 343 is formed at the tail of the first pin 341, and a second mounting piece 345 is formed by tearing in the middle of the first pin 341. The second pressure plate 343 is riveted onto the second wire core. A fourth slit 347 is longitudinally arranged on the second mounting cylinder 346, and the cylinder walls on both sides of the fourth slit 347 are interlocked by second engagement teeth 348. A second mounting hole 349 is provided at the tail of the first mounting cylinder 346. A second locking piece 350 is formed by tearing in the head of the second mounting cylinder 346. The first pin 341 is inserted into the second mounting cylinder 346, and the second mounting piece 345 protrudes from the second mounting hole 349. The second locking piece 350 is locked into the hole of the second terminal module 340. The first pin 341 and the second mounting cylinder 346 are manufactured using a stamping process. The second wire core is inserted into the first pin 341. The third slit 342 allows the second wire core to slightly expand the first pin 341. The second pressure plate 343 rivets the second wire core in place. Then, the first pin 341 is inserted into the second mounting cylinder 346. The second mounting cylinder 346 compresses the first pin 341, causing the inner wall of the first pin 341 to compress the second wire core, resulting in better contact quality. The two sides of the cylinder walls of the fourth slit 347 of the second mounting cylinder 346 interlock, preventing the second mounting cylinder 346 from expanding and ensuring good stability. When the first pin 341 is inserted into the second mounting cylinder 346, the second mounting plate 345 protrudes from the second mounting hole 349. The second mounting plate 345 is then bent, assembling the first pin 341 and the second mounting cylinder 346 together securely. The two sides of the cylinder walls on the fourth slit 347 on the second mounting cylinder 346 interlock, a design that facilitates the second mounting cylinder 346 enclosing the first pin 341. The hole of the second terminal module 340 is larger in the middle and smaller at both ends. When the second terminal module 340 is inserted into the hole, the second locking piece 350 engages within the hole, thus fixing the second terminal module 340 in place. This design makes the assembly of the second terminal module 340 very convenient and efficient.

[0040] Please refer to Figure 7As shown, the first insulating base 210 has several first grooves 213, and first connecting posts 214 are formed between the first grooves 213; the second insulating base 220 has several first partition plates 224, and first connecting holes 225 are formed between the first partition plates 224; a first phase change heat-conducting sheet 216 is disposed in the first groove 213; the first connecting post 214 has a first arc-shaped protrusion 215, and the inner wall of the first connecting hole 225 has a first arc-shaped opening 226; the first connecting post 214 is inserted into the first connecting hole 225, the first partition plate 224 presses the first phase change heat-conducting sheet 216, and the first arc-shaped protrusion 215 is embedded in the first arc-shaped opening 226. The first terminal module 230 passes through the first connecting post 214. The first grooves 213 are interwoven in a grid pattern. The shape of the first phase change heat-conducting sheet 216 is adapted to the first groove 213. The first phase change heat-conducting sheet 216 is attached to the first groove 213. When the first insulating base 210 and the second insulating base 220 are assembled together, the first partition plate 224 presses down on the first phase change heat-conducting sheet 216 in the first groove 213. This design improves the heat conduction between the first insulating base 210 and the second insulating base 220, allowing for more even heat transfer and improving heat dissipation efficiency. When the first connecting post 214 is inserted into the first connecting hole 225, the first arc-shaped protrusion 215 is embedded in the first arc-shaped opening 226. This design improves the assembly firmness and precision between the first connecting post 214 and the first connecting hole 225. A first heat-conducting plate 217 is injection-molded at the interval between the first terminal module holes 201 on the first insulating base 210. The first heat-conducting plate 217 is in contact with the first heat-spreading plate 130, and the heat from the first heat-conducting plate 217 can be transferred to the first heat-spreading plate 130. This design can quickly dissipate heat from the first insulating base 210, helping to improve heat dissipation efficiency. The first heat-conducting plate 217 is separated from the first terminal module 230, and the two are insulated by a first insulating base 210.

[0041] Please refer to Figure 8As shown, the third insulating base 331 has several second grooves 333, and second connecting posts 334 are formed between the second grooves 333; several second partition plates 317 are formed in the second mounting groove 313, and second connecting holes 318 are formed between the second partition plates 317; a second phase change heat-conducting sheet 335 is disposed in the second groove 333; the second connecting post 334 has a second arc-shaped protrusion 336, and the inner wall of the second connecting hole 318 has a second arc-shaped opening 319; the second connecting post 334 is inserted into the second connecting hole 318, the second partition plate 317 presses the second phase change heat-conducting sheet 335, and the second arc-shaped protrusion 336 is embedded in the second arc-shaped opening 319. The second terminal module 340 passes through the second connecting post 334. When the third insulating base 331 is inserted into the second mounting groove 313, the second connecting post 334 is inserted into the second connecting hole 318, and the second partition plate 317 presses down on the second phase change heat-conducting sheet 335 in the second groove 333. This design can improve the thermal conductivity between the second outer shell 310 and the third insulating base 331, and improve the heat dissipation efficiency. The second phase change heat-conducting sheet 335 is mesh-shaped and adapted to the structure of the second groove 333. When the second connecting post 334 is inserted into the second connecting hole 318, the second arc-shaped protrusion 336 is inserted into the second arc-shaped opening 319. This design can improve the assembly firmness and precision between the second connecting post 334 and the second connecting hole 318. A second heat-conducting plate 336 is injection-molded into the space between the holes of the second terminal module 340 on the third insulating base 331. The second heat-conducting plate 336 is in contact with the second heat spreader 320, and the heat from the second heat-conducting plate 336 can be transferred to the second heat spreader 320. This design can quickly dissipate heat from the third insulating base 331, which helps to improve heat dissipation efficiency. The second heat-conducting plate 336 and the second terminal module 340 are separated by the second insulating base 220 for insulation.

[0042] Among them, phase change heat sinks are a type of high-efficiency thermal interface material based on phase change material (PCM). By filling the tiny gaps on the contact surface, they reduce thermal resistance and improve heat dissipation efficiency.

[0043] Please refer to Figure 10As shown, a first heat spreader 130 is disposed inside the first outer shell 110; the heat absorption area of ​​the first heat spreader 130 is in contact with the first insulating base 210 and the second insulating base 220, and the contact surfaces of the first insulating base 210, the second insulating base 220 and the first heat spreader 130 are coated with a first thermally conductive silicone grease; the heat dissipation area of ​​the first heat spreader 130 extends from the first outer shell 110, and a first heat dissipation fin 131 is welded onto the heat dissipation area; a second heat spreader 320 is disposed in the second outer shell 310; the heat absorption area of ​​the second heat spreader 320 is in contact with the third insulating base 331, and the contact surfaces of the third insulating base 331 and the second heat spreader 320 are coated with a second thermally conductive silicone grease; the heat dissipation area of ​​the second heat spreader 320 is exposed in the second outer shell 310, and a second heat dissipation fin 321 is welded onto the heat dissipation area. The first heat spreader 130 and the second heat spreader 320 are thin-walled heat spreaders. The first outer shell 110 and the first vapor chamber 130 are joined together using injection molding. When molding the first outer shell 110 and the first vapor chamber 130, the vapor chamber 110 and the first vapor chamber 130 can be injection molded together first, then a cooling medium can be injected into the first vapor chamber 130, and finally the first vapor chamber 130 can be welded shut. Alternatively, the first vapor chamber 130 can be directly injection molded into the first outer shell 110 as a single unit. The heat absorption area of ​​the first vapor chamber 130 absorbs the heat from the first insulating base 210 and the second insulating base 220, and then the heat is dissipated by the first heat dissipation fins 131 on the heat dissipation area. This design improves the heat dissipation capacity of the male connector 10. The second outer shell 310 and the second vapor chamber 320 are joined together using injection molding. When molding the second outer shell 310 and the second vapor chamber 320, the vapor chamber 310 and the second outer shell 310 can be injection molded together first, then a cooling medium can be injected into the second vapor chamber 320, and finally the second vapor chamber 320 can be welded shut. Alternatively, the second vapor chamber 320 can be injection molded directly into the second housing 310 as a single unit. The heat absorption area of ​​the second vapor chamber 320 absorbs the heat from the third insulating base 331, and then the heat is dissipated by the second heat dissipation fins 321 on the heat dissipation area. This design improves the heat dissipation capacity of the female connector 30. Therefore, under the action of the first vapor chamber 130 and the second vapor chamber 320, this type of connector has better heat dissipation capacity and a greater load capacity.

[0044] Please refer to Figure 10As shown, the first heat spreader 130 is bent; a support 116 is formed on the outer wall of the first housing 110, and the heat dissipation area of ​​the first heat spreader 130 is suspended and passes through the support 116; the edge of the heat absorption area of ​​the first heat spreader 130 has a first flange 132, which is embedded in the wall panel of the first housing 110; the edge of the heat absorption area of ​​the second heat spreader 320 has a second flange 322, which is embedded in the wall panel of the second housing 310. The bent shape of the first heat spreader 130 allows the heat absorption area of ​​the first heat spreader 130 to fully contact the first insulating base 210 and the second insulating base 220, while facilitating the heat dissipation area of ​​the first heat spreader 130 to extend from the first housing 110 for heat dissipation. This design is more conducive to the internal structural layout of the connector. The heat dissipation area of ​​the first heat spreader 130 is suspended on the support 116, which helps to increase the heat dissipation area and allows the first heat sink fins to be welded on both sides of the heat dissipation area, thus improving heat dissipation efficiency. The first flange 132 is embedded in the wall panel of the first outer casing 110, so that the first heat spreader 130 can be well positioned and will not loosen. The second flange 322 is embedded in the wall panel of the second outer casing 310, so that the second heat spreader 320 can be well positioned and will not loosen.

[0045] Please refer to Figure 2-3 As shown, the first outer casing 110 has a cable inlet 126, with a metal ring 122 and an elastic first sealing ring 125 embedded in the cable inlet 126. The metal ring 122 has several fifth slits 123. The first sealing ring 125 is inside the metal ring 122 and is pressed against the cable inlet 126 by barbs 124 on the metal ring 122. The cable inlet shell 121 is tightened onto the cable inlet 126, and the inner wall of the cable inlet shell 121 presses against the metal ring 122. The first cable has several first wire cores. The first sealing ring 125 is embedded inside the metal ring 122 and pressed against the cable inlet 126 by barbs 124 on the metal ring 122. Under the action of the barbs 124, the first sealing ring 125 will not fall off or displace. The first cable passes through the inlet 126. As the inlet housing 121 is screwed onto the inlet 126, the metal ring 122 will squeeze the first sealing ring 125, so that the first sealing ring 125 can firmly wrap the cable. This design structure is simple and has good waterproof ability, preventing water from entering the connector through the inlet 126.

[0046] Please refer to Figure 5-6As shown, the locking post 311 has a T-shaped cross-section; an elastic protrusion 415 is provided on the wall of the locking hole 414, which can press the locking post 311 tightly against the end of the locking hole 414; a rotating shaft 119 is provided on the outer wall of the first housing 110, and the rotating shaft 119 has a second limiting part 117; a rotating shaft hole 416 is provided on the locking frame 410; the rotating shaft 119 is inserted into the rotating shaft hole 416, and the second limiting part 117 presses against the opening of the rotating shaft hole 416. The structure of the locking hole 414 is adapted to the shape of the locking post 311. This design can improve the fit between the locking frame 410 and the locking post 311, and also prevent the locking frame 410 from loosening. A hole is provided on one side of the locking hole 414, and an elastic protrusion 415 is formed on this side, which can undergo elastic deformation. When the locking pin 311 is inserted into the locking hole 414, the elastic protrusion 415 can press the locking pin 311 tightly against the end of the locking hole 414. This design can limit the locking pin 311 and ensure that the locking pin 311 does not shift in the locking hole 414, thus improving its stability.

[0047] The rotating shaft 119 can rotate on the rotating shaft hole 416. The rotating shaft 119 is inserted into the rotating shaft hole 416 on the locking bracket 410, and the second limiting part 117 on the rotating shaft 119 presses against the opening of the rotating shaft hole 416. This design can ensure that the rotating shaft 119 and the rotating shaft hole 416 will not come loose, and improve the assembly firmness between the locking bracket 410 and the rotating shaft 119.

[0048] Please refer to Figure 5-6 As shown, the locking bracket 410 has an elastic portion 417 and a first stop 418 on its left and right inner sides; the first outer shell 110 has a second stop 118 and a pivot seat 120 on its left and right outer walls; a pivot 119 is formed on the pivot seat 120; the elastic portion 417 presses against the pivot seat 120; the first stop 418 can be stopped by the second stop 118. The stopping cooperation of the first stop 418 and the second stop 118 can control the rotation angle of the locking bracket 410. When the locking bracket 410 is assembled with the first outer shell 110, the elastic portion 417 presses against the pivot seat 120. This design allows the locking bracket 410 to be centrally positioned on the first outer shell 110. At the same time, the elastic portion 417 can also provide a certain amount of damping, improving the tightness of the assembly.

[0049] In summary, the key design feature of this invention is that when the male connector 10 and female connector 30 need to be locked, the locking bracket 410 is swung to allow the locking pin 311 to pass into the locking hole 414; then, the limiting member 420 is moved to allow the first slide rail 423 to extend into the first limiting groove 111; when the male connector 10 and female connector 30 need to be separated, the limiting member 420 is simply reset to allow the first slide rail 423 to exit from the first limiting groove 111, thus allowing the locking bracket 410 to be swung to allow the locking pin 311 to exit from the locking hole 414. Therefore, this locking device 40 has good stability and is very convenient to operate.
