Description

Technical Field

[0001] The present invention relates to the technical field of connectors, in particular to a cabinet connector. Background Art

[0002] The cabinet connector is a special connector that allows a stable connection between the unit and the mounting frame. This connector is designed to ensure that the unit can be firmly installed in the cabinet while maintaining good electrical and mechanical connections. The mating and fixing characteristics of the cabinet connector guarantee the reliability and stability of the connection, which is essential to ensure the normal operation of the equipment.

[0003] Today's cabinet connectors may often overheat due to poor contact. When the contact points of the connectors are in poor contact due to oxidation, contamination or other reasons, the resistance will increase, and the increase in resistance will cause heat accumulation in local areas. This heat accumulation may cause the connector to overheat, which in turn affects its service life and performance. In addition, poor contact may also cause spark discharge, which is also an important source of heat, especially in the process of separation and re-contact of the contact points. Spark discharge will generate a lot of heat, further aggravating the overheating of the connector. When the connector is overheated and the temperature rises too high, measures need to be taken to intervene, which indicates that the contact part will generate a large resistance when current passes through, resulting in local heating. If this heating cannot be effectively handled, it will cause local overheating of the connector and even cause safety accidents such as fire, which may cause equipment failure or damage. Therefore, in order to deal with this heating phenomenon in a timely manner, it is necessary to improve the existing cabinet connectors. Summary of the invention

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present invention provides a cabinet connector having the following beneficial effects:

[0017] 1. The present invention transfers the heat generated by the poor contact between the first contact piece and the second contact piece to the copper box through the copper box, and the mercury in the copper box that expands due to the heat flows into the side cavity through the side pipe to push the L-shaped block, so that the L-shaped block drives the square sleeve to move toward the first outer shell, so that the square sleeve pulls the piston block to squeeze the gas inside the piston square cylinder through the rigid spring and the convex long rod, and then the compressed gas inside the piston square cylinder is discharged through the connecting pipe and the first contact piece.

[0018] 2. The present invention pushes the square sleeve, so that the square sleeve pushes the piston block to move through the rigid spring and the convex long rod, and then the piston block compresses the gas inside the piston square cylinder, so that the gas inside the piston square cylinder squeezes the first sphere through the connecting hole to block the first sealing ring and compress the first flexible spring, and then the gas inside the piston square cylinder enters the second sealing ring to squeeze the second sphere, so that the second sphere opens the second sealing ring and stretches the second flexible spring, and then the gas blows out the impurities stuck inside the first contact piece through the connecting pipe.

[0032] Embodiment 1, according to Figure 1-10As shown, a cabinet connector includes a connecting plug assembly 1 and a connecting socket assembly 2, wherein the connecting plug assembly 1 includes a first outer shell 101 and a first contact 102, wherein the first contact 102 is installed in the first outer shell 101, and the connecting socket assembly 2 includes a second outer shell 201 and a second contact 202, wherein the second contact 202 is installed in the second outer shell 201, wherein a copper box 3 filled with mercury is fixed inside the first outer shell 101, and a side cavity 10 is opened inside the left end of the first outer shell 101, wherein the inside of the side cavity 10 is movable An L-shaped block 11 is sleeved, and the other end of the L-shaped block 11 is fixedly connected to a square sleeve 5 that is movably sleeved on the outer surface of the first outer shell 101. A side pipe 12 that is connected to the side cavity port 10 and the copper box 3 is opened inside the first outer shell 101. A piston square cylinder 9 is fixed to the left end of the first outer shell 101. A convex long rod 6 is movably sleeved inside the square sleeve 5. A rigid spring 7 is fixed to the side of the convex long rod 6. The other end of the rigid spring 7 is fixedly connected to the square sleeve 5. The other end of the convex long rod 6 is fixedly connected to a movably sleeved inner surface of the piston square cylinder 9. The first outer shell 101 is provided with a connecting pipe 4 connecting the first contact piece 102 and the piston square cylinder 9. When the first contact piece 102 and the second contact piece 202 are overheated due to poor contact, the copper box 3 of the first contact piece 102 will transfer heat to the mercury inside the copper box 3, and then the mercury inside the copper box 3 will flow into the side cavity 10 through the side pipe 12 to push the L-shaped block 11, so that the L-shaped block 11 drives the square sleeve 5 to move toward the first outer shell 101. Then, the square sleeve 5 pulls the piston block 8 through the rigid spring 7 and the convex long rod 6 to squeeze the gas inside the piston square tube 9, and then the compressed gas inside the piston square tube 9 is discharged through the connecting pipe 4 and the first contact piece 102. At this time, the connecting plug assembly 1 is sleeved inside the connecting socket assembly 2, so that the gas quickly squeezes the connecting plug assembly 1 out of the connecting socket assembly 2 as a whole, so that the connecting plug assembly 1 can be squeezed out when overheating occurs, so as to prevent local overheating of the connecting plug assembly 1 and cause safety accidents such as fire.

[0033] according to Figure 6 As shown, the copper box 3 is located at the right end of the first outer shell 101, and the first contact piece 102 is located inside the copper box 3. Through the position design of the first contact piece 102 and the copper box 3, when the first contact piece 102 overheats due to poor contact, the copper box 3 can be better heated and transfer the heat to the mercury inside the copper box 3, so that the mercury can better sense the heat.

[0034] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below for details.

[0035] Embodiment 2, according to Figure 7 As shown, a connecting port 20 is provided inside the right end of the first outer shell 101, and a long hook block 21 is hinged inside the connecting port 20. An elastic sheet 22 is fixed to the bottom of the long hook block 21, and the lower end of the elastic sheet 22 is fixedly connected to the inner wall of the connecting port 20. A long hook groove 25 for hooking the long hook block 21 is provided inside the second outer shell 201. Through the design of the long hook block 21 and the long hook groove 25, when the elastic sheet 22 is rotated into the long hook groove 25 by squeezing the long hook block 21, the elastic sheet 22 fixes the connecting plug assembly 1 in the connecting socket assembly 2 by hooking the long hook groove 25, so that when the connecting plug assembly 1 and the connecting socket assembly 2 are in use, the connecting plug assembly 1 is not easy to detach from the connecting socket assembly 2, thereby preventing the connecting plug assembly 1 and the connecting socket assembly 2 from loosening during use.

[0036] according to Figure 7 As shown, the internal movable sleeve of the communication port 20 is connected with a push block 23, and the other end of the push block 23 is fixedly connected to the inner wall of the square sleeve 5. Through the design of the push block 23, when the square sleeve 5 pulls the piston block 8 to move along the inner wall of the piston square cylinder 9 through the rigid spring 7 and the convex long rod 6, the piston block 8 squeezes the gas inside the piston square cylinder 9. At this time, the long hook block 21 hooks the long hook groove 25 to fix the connecting plug assembly 1 inside the connecting socket assembly 2, so that the gas inside the piston square cylinder 9 cannot be discharged through the connecting pipe 4 and the first contact member 102 and squeeze the piston block 8. As the mercury passes through the L-shaped block 11 Continue to push the square sleeve 5 to move, so that the square sleeve 5 stretches the rigid spring 7 to further pressurize the convex long rod 6 and the piston block 8, and at the same time, the square sleeve 5 will drive the pushing block 23 to squeeze the long hook block 21, so that the long hook block 21 rotates and compresses the elastic sheet 22, until the long hook block 21 is separated from the long hook groove 25 and stops. At this time, the compressed gas inside the piston square tube 9 will be discharged through the connecting pipe 4 and the first contact piece 102, so that the gas can quickly squeeze the connecting plug assembly 1 out of the connecting socket assembly 2 as a whole, thereby achieving the purpose of quickly squeezing out the connecting plug assembly 1.

[0037] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below for details.

[0038] Embodiment 3, according to Fig.10As shown, a second sealing ring 17 is fixedly sleeved inside the left end of the connecting pipe 4, and a second spherical body 19 is blocked at the right end of the second sealing ring 17. A second flexible spring 18 is fixed on the second spherical body 19, and the other end of the second flexible spring 18 is fixedly connected to the second sealing ring 17. Through the design of the second sealing ring 17, the second flexible spring 18 and the second spherical body 19, the gas inside the piston square cylinder 9 can only be discharged into the connecting pipe 4 through the second sealing ring 17, and the gas inside the connecting pipe 4 cannot flow back to the piston square cylinder 9 through the second sealing ring 17, because when the gas in the connecting pipe 4 flows back, the gas will squeeze the second spherical body 19 to better seal the second sealing ring 17.

[0039] according to Figure 5 As shown, a connecting hole 13 is provided inside the convex long rod 6, a first sealing ring 14 is fixedly sleeved inside the right end of the connecting hole 13, a first spherical body 15 is blocked at the left end of the first sealing ring 14, a first flexible spring 16 is fixed on the first spherical body 15, and the other end of the first flexible spring 16 is fixedly connected to the first sealing ring 14. Through the design of the first sealing ring 14, the first spherical body 15 and the first flexible spring 16, when the square sleeve 5 is pushed, the square sleeve 5 compresses the gas inside the piston square cylinder 9 by pulling the piston block 8, thereby causing the gas inside the piston square cylinder 9 to squeeze the first spherical body 15 through the connecting hole 13 to block the first sealing ring 14 and compress the first flexible spring 16. , and at the same time, the gas inside the piston square cylinder 9 enters the second sealing ring 17 to squeeze the second sphere 19, so that the second sphere 19 opens the second sealing ring 17 and stretches the second flexible spring 18, so that the gas blows out the impurities adhered to the first contact piece 102 through the connecting pipe 4. When the square sleeve 5 is pulled, the second flexible spring 18 will pull the second sphere 19 to close the second sealing ring 17, and at the same time, the first flexible spring 16 will squeeze the first sphere 15 to open the first sealing ring 14, so that the external gas enters the interior of the piston square cylinder 9 through the first sealing ring 14 and the connecting hole 13, thereby achieving the purpose of cleaning the first contact piece 102.

[0040] according to Figure 7 As shown, a connecting wire 26 is installed on the first outer shell 101, and one end of the connecting wire 26 is electrically connected to the first contact piece 102. Through the design of the connecting wire 26 and the first contact piece 102, the connecting wire 26 can introduce external current to the first contact piece 102, so that the first contact piece 102 and the second contact piece 202 can be electrically connected for use.

[0041] according to Figure 8As shown, a circular opening 24 is provided inside the square sleeve 5, and the inner dimension of the circular opening 24 is larger than the outer diameter of the connecting wire 26. Through the design of the circular opening 24, when the square sleeve 5 is pushed or pulled, the circular opening 24 can quickly discharge the air inside the square sleeve 5, thereby making the square sleeve 5 smoother when pushed or pulled.

[0042] When used specifically, the present invention is used as a cabinet connector. First, the connecting socket assembly 2 is fixedly installed on the cabinet and electrically connected to the cabinet. Then, the first outer shell 101 is held and the square sleeve 5 is pushed, so that the square sleeve 5 drives the pushing block 23 to move along the inner wall of the connecting port 20, and then the pushing block 23 squeezes the long hook block 21 to rotate, so that the long hook block 21 squeezes the elastic sheet 22 to bend, and then the connecting plug assembly 1 is inserted into the connecting socket assembly 2, and the first contact piece 102 and the second contact piece 202 are electrically connected. Then, the square sleeve 5 is loosened, so that the elastic sheet 22 squeezes the long hook block 21 to rotate, until the long hook block 21 rotates to the inside of the long hook groove 25 and stops, so that the elastic sheet 22 fixes the connecting plug assembly 1 inside the connecting socket assembly 2 by hooking the long hook groove 25, thereby preventing the connecting plug assembly 1 and the connecting socket assembly 2 from loosening during use.

[0043] When the first contact piece 102 on the connecting plug assembly 1 and the second contact piece 202 on the connecting socket assembly 2 overheat due to poor contact, the copper box 3 close to the first contact piece 102 will transfer heat to the mercury inside the copper box 3, so that the mercury inside the copper box 3 expands due to the heat, and then the mercury inside the copper box 3 flows into the side cavity 10 through the side pipe 12, and the expanded mercury pushes the L-shaped block 11 to move along the inner wall of the side cavity 10, and then the L-shaped block 11 drives the square sleeve 5 to move toward the first outer shell 101, so that the square sleeve 5 will pull the piston block 8 along the inner wall of the piston square tube 9 through the rigid spring 7 and the convex long rod 6, so that the piston block 8 squeezes the gas inside the piston square tube 9. At this time, since the connecting plug assembly 1 is inserted into the connecting socket assembly 2, and the long hook block 21 hooks the long hook groove 25, the gas inside the piston square tube 9 cannot pass through the connecting pipe 4 and the first A contact piece 102 is discharged and squeezes the piston block 8. As the mercury continues to push the square sleeve 5 to move through the L-shaped block 11, the square sleeve 5 will stretch the rigid spring 7 to further pressurize the convex long rod 6 and the piston block 8. At the same time, the square sleeve 5 will drive the pushing block 23 to squeeze the long hook block 21, so that the long hook block 21 rotates and compresses the elastic sheet 22 until the long hook block 21 is separated from the long hook groove 25 and stops. At this time, the long hook block 21 will release the fixing effect on the connecting plug assembly 1, and then the compressed gas inside the piston square cylinder 9 will be discharged through the connecting pipe 4 and the first contact piece 102, and the connecting plug assembly 1 will be quickly squeezed out of the connecting socket assembly 2 as a whole. Such a design allows the device to overheat due to poor contact between the first contact piece 102 and the second contact piece 202. The connecting plug assembly 1 can be squeezed out to prevent local overheating of the connecting plug assembly 1 from causing safety accidents such as fire.

[0044] When the first contact member 102 has poor contact due to adhesion of impurities, the operator pushes the square sleeve 5, which will cause the square sleeve 5 to push the piston block 8 to move through the rigid spring 7 and the convex long rod 6, so that the piston block 8 compresses the gas inside the piston square cylinder 9, so that the gas inside the piston square cylinder 9 squeezes the first sphere 15 through the connecting hole 13 to block the first sealing ring 14 and compress the first flexible spring 16, so that the gas inside the piston square cylinder 9 enters the second sealing ring 17 to squeeze the second sphere 19, so that the second sphere 19 opens the second sealing ring 17 and stretches the second flexible spring 18, so that the gas can blow out the impurities stuck inside the first contact piece 102 through the connecting pipe 4, and then by pulling the square sleeve 5, the second flexible spring 18 will pull the second sphere 19 to close the second sealing ring 17, and at the same time, the first flexible spring 16 will squeeze the first sphere 15 to open the first sealing ring 14, so that the external gas can enter the interior of the piston square tube 9 through the first sealing ring 14 and the connecting hole 13. In this way, the reciprocating push and pull of the square sleeve 5 can clean the impurities stuck inside the first contact piece 102 through the gas, effectively avoiding the poor contact of the first contact piece 102 due to the sticking of impurities.

[0045] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
