The top end of the reset spring 83 is fixedly connected with the left end of the inner cavity of the hollow tube 82, the outer surface of the reset spring 83 is in sliding connection with the left side of the inner wall of the outer pipe sleeve 81, the outer surface of the vent whistle 84 is in sliding connection with the left side of the inner wall of the outer pipe sleeve 81, the bottom end of the vent whistle 84 extends to the outside of the outer pipe sleeve 81, under normal conditions, the vent whistle 84 contracts into the inside of the outer pipe sleeve 81 under the tensile force action of the reset spring 83, when the inside of the distribution box 1 is overheated or abnormally fires, the vent whistle 84 slides downwards due to gas expansion, gas is finally discharged to the outside from the whistle of the vent whistle 84, gas exchange is carried out in a forward manner, heat is dissipated inside the distribution box, and the vent whistle 84 sounds to play a role of alarming around.
The specific working process is as follows:
when installing this block terminal, the user inserts distribution module 13 into the fixed frame 5 of electrical apparatus through the square mouth of special-made case shell 11, after stable, peg graft main guide wire 12 in the inner chamber of the fixed frame 5 of each electrical apparatus, under the linkage action of the fixed frame 5 of electrical apparatus, distribution module 13 is connected with main guide wire 12 indirectly, accomplish the installation work, when a certain distribution module 13 transships, main guide wire 12 also can transship, and then lead to the insurance of tension device 6 to start, pull out the fixed frame 5 of electrical apparatus with distribution module 13, cut off the fixed frame 5 of electrical apparatus, distribution module 13, the relation of connection between the main guide wire 12 three, when having prevented the emergence of single distribution module 13 accident that fires, do not influence the normal work of all the other distribution modules 13, and then reduced the influence of power failure accident.
When installing the block terminal on a large scale, in order to make the installation simpler, the installation effectiveness is improved, before installing distribution module 13, the user outwards pulls portable tension plate 52, distribution module 13 is on fixed plate 7, insert the middle part of the fixed frame 5 of electrical apparatus with gliding mode, afterwards, loosen portable tension plate 52, portable tension plate 52 resets under elastic effect, compress tightly distribution module 13 and prevent it from becoming flexible, the fixed frame 5 of electrical apparatus afterwards, distribution module 13, main guide line 12 three forms the relation of connection, accomplish distribution module 13's fixed work.
Since the main guide wire 12 for electrical conduction, which is usually a rubber sheath, is susceptible to thermal expansion at ambient temperature, if the round mouth is fixed, on one hand, the fixing plate 7 cannot fix the main guide wires 12 of various types, and on the other hand, the main guide wires 12 are easy to be locked with the round mouth after being heated and expanded, so that the separation work of the power distribution module 13 is blocked, the through round mouth of the plate body 71 is relatively large, and the arc-shaped spring arm 74 is used for fixing the main guide wire 12, when the main guide wire 12 is thermally expanded, the arc-shaped spring arm 74 is also adjusted along with the contraction, so as to prevent the main guide wire 12 from being locked with the round mouth after being thermally expanded, and, at overload, the junction of the main guideline 12 and the distribution module 13 is at a relatively high temperature, also the location most prone to fire, the gap of the fixing ring 72 is filled with the fireproof cotton 73, increasing the heat resistance of the fixing plate 7.
Under the normal condition, when the distribution box is cooled, a heat dissipation port needs to be arranged on the distribution box, but the distribution box with the heat dissipation port is easy to be affected with damp and poor in dust resistance, and if the heat dissipation port is large, the distribution box is easy to be damaged by being gnawed by cockroaches and mice, on one hand, the tension device 6 of the device can pull out the distribution module 13 from the fixed frame 5 of the electric appliance through the tension spring 6, on the other hand, the air flow exchange can be carried out on the inside of the distribution box through the U-shaped modified pipe 8, so that the purpose of heat dissipation is achieved, dust is difficult to accumulate because the pipe orifice of the U-shaped modified pipe 8 is downward, animals such as the cockroaches and the mice are difficult to enter, the back of the hollow sliding frame 61 is provided with the safety hinge plate 64, when the distribution module 13 is overloaded, the main guide wire 12 is short-circuited, the current passing through the auxiliary wire for fixing the safety spring rod 65 is increased, so that the fuse inside the safety spring rod 65 is fused, at this time, the two ends of the fixed safety spring rod 65 extend towards the two ends under the action of the same row, the opening angle of the safety hinge plate 64 is increased, one end of the safety hinge plate 64 is fixedly connected with the outer surface of the special box shell 11, and the other end of the safety hinge plate 64 pushes the hollow sliding frame 61 to slide leftwards, so that the power distribution module 13 slides out of the hollow sliding frame 61, and the power distribution module 13 is prevented from being overheated and ignited due to overlong contact time with the main guide wire 12.
Under normal conditions, the vent whistle 84 contracts into the outer pipe sleeve 81 under the action of the tension of the return spring 83, when the inside of the distribution box 1 is overheated or abnormally ignited, the vent whistle 84 slides downwards due to gas expansion, and finally gas is discharged to the outside from the whistle of the vent whistle 84, gas exchange is carried out along the belt, heat is dissipated inside the distribution box, and the vent whistle 84 sounds to play a role in alarming the periphery.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
