Second embodiment

In the working process of the first embodiment, it is found that, because a temperature difference is generated by four seasons, especially in cold weather, the sealing component 3 becomes hard and brittle, so that the sealing property of the sealing component 3 is deteriorated, and meanwhile, the vibration buffer property of the sealing component 3 on the bus connector is reduced, which easily causes gaps between the bus copper connecting rod 402 and the tapered copper contact 201 and between the bus copper connecting rod and the spherical copper contact 204, and under the action of high current, an arc is generated at the gaps, which not only causes large heating value at the joints, but also causes the conditions of melting at the joints easily due to frequent arc generation, and then easily causes breakdown, and then the sealing protection of the sealing component 3 is greatly reduced, and the sealing component 3 is accelerated to break due to the conditions of melting or burning caused by too high temperature, so that the bus copper connecting rod 402 in the connector is exposed in the air, the safety is greatly reduced, and finally the electrical equipment is shorted and damaged, in addition, the connector generates heat, especially in high-temperature working, the conditions of melting at the joints are greatly influenced, and the following working characteristics are solved:

as shown in fig. 7 to 11, the outer side wall of the sealing component 3 is fixedly provided with a protection component 5, the inner side wall of the sealing component 3 is fixedly provided with a fixing ring 501 sleeved on the outer side wall of the connecting component 4, the protection component 5 comprises a flame-retardant protection ring 505 sleeved on the outer side wall of the sealing component 3, an annular storage groove 304 is arranged in the sealing component 3, an annular airbag 504 which is symmetrical and corresponds to the connecting component 4 is fixed on the inner side wall of the annular storage groove 304, the annular storage groove 304 is communicated with the inner cavity of the fixing ring 501 through a first liquid guide pipe 502, the annular storage groove 304 is communicated with the flame-retardant protection ring 505 through a second liquid guide pipe 503, a first small water pump is fixedly arranged on the first liquid guide pipe 502, a second small water pump is fixedly arranged on the second liquid guide pipe 503, and an electric control valve is arranged on the outer side wall of the flame-retardant protection ring 505.

During actual use, under low temperature environment, seal assembly 3 can harden, lead to the limiting displacement to coupling assembling 3 to reduce, when vibration or pulling force take place on the connector this moment, generating gap with conical copper contact 201 and ball-type copper contact 204 of generating bus copper connecting rod 402, can lead to the gap department to produce electric arc like this, the production of electric arc can produce heat, and the heat can carry out the heat conduction through solid fixed ring 501 and effectively convert, can heat treatment to seal assembly 3 through the heat conduction effect of solid fixed ring 501 like this, can promote seal assembly 3 to resume toughness and elasticity, resume the buffering limiting displacement to the connector.

It should be noted that, in the process that the bus bar copper connecting rod 402 generates gaps with the conical copper contact 201 and the spherical copper contact 204, since the contact blade 4012 and the bus bar copper connecting rod 402 have a tendency to separate, the end portion of the contact blade 4012 moves outwards along with the increase of the tensile force, then the tension spring 4014 is pressed, and then the fixing ring 501 is pressed, so that the pressing force acts on the annular air bag 504 to cause the annular air bag 504 to compress, and the degree of separation between the contact blade 4012 and the bus bar copper connecting rod 402 can be reflected in real time through the compression amount of the annular air bag 504.

When the compression amount of the annular air bag 504 reaches the first threshold, the controller controls the first small water pump to be turned on, so that the cooling liquid in the annular storage tank 304 is led into the fixed ring 501 through the first liquid guide pipe 502, and the cooling water flowing into the fixed ring 501 is heated by the heat generated by the electric arc, so that the purpose of harm is achieved, the pressure of the fixed ring 501 on the connecting assembly 4 can be increased by the weight of the led cooling liquid, the possibility that the contact blade 4012 and the bus copper connecting rod 402 are separated is greatly reduced, and the possibility that gaps among the conical copper contact 201, the spherical copper contact 204 and the bus copper connecting rod 402 are increased is also reduced.

However, when the external tension increases to cause the gap between the conical copper contact 201, the spherical copper contact 204 and the bus copper connecting rod 402 to be gradually enlarged, at this moment, under the action of external force, the contact blade 4012 overcomes the limit action of the tensioning spring 4014 and the fixed ring 501 to cause the tensioning spring 4014 to be continuously stretched, and meanwhile, the fixed ring 501 is jacked up by the movable contact blade 4012, so that the extrusion force of the annular air bag 504 is increased through the fixed ring 501, when the compression amount of the annular air bag 504 reaches a second threshold value, the relative displacement amount of the conical copper contact 201, the spherical copper contact 204 and the bus copper connecting rod 402 is shown to reach the limit at this moment, and at this moment, the controller controls the electromagnetic locking assembly 506 to act, so that the electromagnetic locking assembly 506 can limit and fix the conical copper contact 201 and the sealing assembly 3, and simultaneously, the electromagnetic locking assembly 506 can limit and fix the spherical copper contact 204 and the limiting ring 11, and prevent the conical copper contact 201, the spherical copper contact 204 and the bus copper connecting rod 402 from being separated, thereby not only improving the anti-separation performance, but also avoiding frequent use of the conical copper contact 201, the spherical copper contact 204 and the bus copper connecting rod 402.

It is noted that after the electromagnetic locking assembly 506 works for a period of time T, the controller controls the electromagnetic locking assembly 506 to reset, and at this time, the cooling liquid in the annular storage groove 304 is still stored in the fixed ring 501, so that the pressure is conveniently applied to the connecting assembly 4, and heat generated by an electric arc can be absorbed, so that the sealing assembly 3 is conveniently heated, and the protection is improved.

When the connector is at high temperature, the annular airbag 504 can expand based on the rise of the external temperature, so that the annular airbag 504 is heated and expanded to generate extrusion force on the fixed ring 501, extrusion force of the fixed ring 501 on the connecting assembly 4 can be provided, connection stability among the conical copper contact 201, the spherical copper contact 204 and the bus copper connecting rod 402 is improved, and meanwhile, monitoring of the external temperature can be realized through the expansion amount of the annular airbag 504.

When the expansion amount of the annular air bag 504 reaches the first threshold, the first small water pump is turned on, so that the cooling liquid in the annular storage tank 304 can be led into the fixed ring 501, and the cooling liquid can circulate in the fixed ring 501, thereby facilitating the preliminary cooling treatment of the connector.

With the rise of temperature, the expansion amount of the annular air bag 504 can be further increased, when the expansion amount of the annular air bag 504 is increased to the second threshold value, hot steam is generated in the fixed ring 501 at this time, and the first small water pump works reversely, so that the hot steam can flow back into the annular storage tank 304 through the first liquid guide pipe 502, heat release is conveniently realized, cooling liquid is conveniently condensed from steam, and the cooling liquid is conveniently led into the fixed ring 501 again through the first liquid guide pipe 502 for heat conduction from the annular storage tank 304 after the first small water pump is turned on next time, so that cooling operation is realized.

It should be noted that, when the steam is retained in the annular storage tank 304, the expansion amount of the annular air bag 504 is increased, when the expansion amount of the annular air bag 504 reaches the third threshold value, it is indicated that the hot steam in the annular storage tank 304 cannot effectively discharge heat, at this time, the second small water pump and the first small water pump are opened simultaneously, so that the cooling liquid in the flame-retardant protection ring 505 is led into the annular storage tank 304 through the second liquid guide tube 503 to realize cooling treatment of the hot steam, and meanwhile, the cooling liquid can also be led into the fixed ring 501 through the first liquid guide tube 502 to realize secondary cooling protection, so that the hot steam can realize heat exchange with the cooling liquid to complete heat absorption, improve cooling effect, and simultaneously realize cooling protection of the annular air bag 504.

When the expansion amount of the annular air bag 504 reaches the fourth threshold, the outside is in a fire state, the electric control valve on the outer side wall of the flame-retardant protection ring 505 is opened, so that the cooling liquid in the flame-retardant protection ring 505 can splash, the outer side wall of the sealing assembly 3 can be wetted, the flame retardance of the sealing assembly 3 can be improved, the use safety of the connector is improved, and meanwhile, later-stage workers can supplement the cooling liquid in the flame-retardant protection ring 505 when carrying out maintenance work, so that the normal use of the connector is ensured.
