As shown in fig. 1 and 2, the flexible connecting mechanism 2 includes: the contact structure comprises a retractable inner ring conductive contact element 21, an outer ring conductive contact element 22 and at least one elastic conductive component 23, wherein the outer ring conductive contact element 22 is coaxially arranged with the inner ring conductive contact element 21 along the preset axial direction, and the elastic conductive component 23 is arranged between the inner ring conductive contact element 21 and the outer ring conductive contact element 22. In practical application, the inner conductive contact element 21 can be sleeved and clamped on the movable contact 31 of the vacuum arc-extinguishing chamber 3 of the recloser by means of the resilience performance of the elastic conductive component 23, and the outer conductive contact element 22 is electrically connected with the conductive rod 4 of the recloser.
It can be seen from the above that, since the flexible connection mechanism 2 is disposed in the shielding housing shell 1, the local discharge phenomenon of the flexible connection mechanism can be shielded by the shielding housing shell 1, thereby avoiding the influence of the flexible connection mechanism 2 on the service life of the insulating housing of the recloser due to discharge. Meanwhile, the flexible connection mechanism 2 is composed of a retractable inner ring conductive contact element 21, an outer ring conductive contact element 22 and an elastic conductive component 23 arranged between the inner ring conductive contact element 21 and the outer ring conductive contact element 22, so that the inner ring conductive contact element 21 can depend on the resilience performance of the elastic conductive component 23, and the flexible connection mechanism is clamped and fixed on the movable contact 31 of the vacuum arc-extinguishing chamber 3, and compared with a fixing mode adopting an insert bolt, the fixing mode is adopted, and the installation of the flexible connection structure of the embodiment is more convenient.
Specifically, in the present embodiment, as shown in fig. 2 and 3, the inner-ring conductive contact 21 includes: two conductive clamping pieces 211 which are symmetrically arranged by taking a preset axis as a symmetry axis. Meanwhile, the elastic conductive components 23 are provided with a plurality of elastic conductive components 23, and the elastic conductive components 23 are sequentially arranged along the direction of the preset axis. And each elastic conductive member 23 includes: a plurality of elastic conductive elements 231 annularly arranged around the preset axial direction at equal intervals. As shown in fig. 3, each elastic conductive element 231 includes: a first end 2311 abutting against one of the conductive clips 211, and a second end 2312 abutting against the outer ring conductive contact piece 22. The elastic conductive element 231 used in the present embodiment may be a spring, but the elastic conductive element 231 may be another elastic member in actual use, and the type of the elastic conductive element 231 is not particularly limited in the present embodiment. Therefore, in practical application, each conductive clamping piece 211 of the inner-ring conductive contact element 21 can tightly hold the movable contact 31 of the vacuum arc-extinguishing chamber 3 under the resilience of each elastic conductive element 231, so that the flexible connection mechanism 2 and the vacuum arc-extinguishing chamber 3 are fixed.
Note that, in the present embodiment, as shown in fig. 2 and 3, one side of each conductive clip 211 of the inner-ring conductive contact 21 with respect to the elastic conductive member 23 is a first conductive outer side 2111, and the opposite side is a first conductive inner side 2112. Correspondingly, one side of the outer-ring conductive contact 22 opposite to the elastic conductive member 23 is a second conductive inner side 221, and the opposite side is a second conductive outer side 222. Also, the first conductive outer side 2111 and the second conductive inner side 221 are opposed and spaced apart.

Similarly, the second conductive inner side 221 of the outer conductive contact 22 is provided with inner grooves 223 corresponding to the elastic conductive elements 231, so that the second ends 2312 of the elastic conductive elements 231 can be embedded in the inner grooves 223 corresponding to the second ends, and the elastic conductive elements 231 are positioned by the inner grooves 223 and the outer grooves 2113, so that the resilient movement of the elastic conductive elements 231 has certain guidance, and the stability and firmness of the clamping connection between the inner conductive contact 21 and the movable contact 31 are further improved.
In addition, in the present embodiment, as shown in fig. 2 and 3, both ends of the first conductive inner side 2112 of each conductive clip 211 are preferably bent and extended in the direction of the first conductive outer side 2111 along the predetermined axial direction, so that the two ends of each conductive clip 211 along the preset axial direction are in a structure of a convex cambered surface, therefore, when the flexible connecting mechanism 2 is assembled with the movable contact 31, only the flexible connecting mechanism 2 needs to be pushed towards the movable contact 31, by means of the contact between the arc surfaces at the two ends of each conductive clamping piece 211 of the inner ring conductive contact piece 21 and the movable contact 31, so that each conductive clip 211 can move horizontally in a direction away from the predetermined axis by itself under the action of the movable contact 31, that is, the whole inner ring conductive contact element 21 can be spread by the moving contact 31 until the flexible connecting mechanism 2 is moved to the clamping position, and the clamping fixation with the moving contact 31 can be automatically realized.

Further, the flexible connection structure of the present embodiment further includes: and the clamping ring 6 is detachably embedded in the annular groove 121, and meanwhile, the clamping ring 6 partially protrudes out of the annular groove 121, so that the clamping ring can be opposite to the supporting surface 13 along the preset axial direction, and the flexible connecting mechanism 2 can be firmly fixed between the clamping ring 6 and the supporting surface 13.
In order to protect the inner conductive contact 21 and the outer conductive contact 22 of the flexible connection mechanism 2 to a certain extent, the flexible connection mechanism 2 preferably further includes: the upper gasket 24 is arranged at the top of the inner ring conductive contact element 21 and the outer ring conductive contact element 22, and the lower gasket 25 is arranged at the bottom of the inner ring conductive contact element 21 and the outer ring conductive contact element 22, so that when the flexible connecting mechanism 2 is clamped and fixed by the clamping ring 6 and the supporting surface 13, the upper gasket 24 can be abutted against the clamping ring 6, and the lower gasket 25 is abutted against the supporting surface 13, so that the phenomenon that the inner ring conductive contact element 21 and the outer ring conductive contact element 22 are crushed due to the fact that the clamping ring 6 and the supporting surface 13 are directly acted on the top and the bottom of the inner ring conductive contact element 21 and the outer ring conductive contact element 22 respectively is effectively avoided.
In addition, in the present embodiment, in order to improve the sealing performance between the shield case 1 and the vacuum interrupter 3 after assembly, as shown in fig. 1, the groove bottom of the positioning groove 11 is provided with the O-ring 7, and the groove bottom of the positioning groove 11 and the bottom of the vacuum interrupter 3 can form a sealing surface by the O-ring 7, thereby improving the sealing performance between the vacuum interrupter 3 and the shield case 1.

Therefore, as the flexible connecting mechanism 2 is arranged in the shielding case shell 1, the local discharge phenomenon of the flexible connecting mechanism can be shielded through the shielding case shell 1, and the influence of the flexible connecting mechanism 2 on the service life of the insulating shell 5 of the recloser due to discharge is avoided. Meanwhile, the flexible connection mechanism 2 is composed of a retractable inner ring conductive contact element 21, an outer ring conductive contact element 22 and an elastic conductive component 23 arranged between the inner ring conductive contact element 21 and the outer ring conductive contact element 22, so that the inner ring conductive contact element 21 can depend on the resilience performance of the elastic conductive component 23, and the flexible connection mechanism is clamped and fixed on the movable contact 31 of the vacuum arc-extinguishing chamber 3, and compared with a fixing mode adopting an insert bolt, the fixing mode is adopted, and the installation of the flexible connection structure of the embodiment is more convenient.
Specifically, in order to satisfy the clamping fixation of each conductive clamping piece 211 of the inner-ring conductive contact piece 21 to the movable contact 31, in the present embodiment, as shown in fig. 5, an annular clamping groove 311 for clamping the inner-ring conductive contact piece 21 is provided on the outer surface of the movable contact 31. When the flexible connection structure of the first embodiment is assembled with the movable contact 31 of the vacuum interrupter 3, the annular clamping groove 311 allows the flexible connection structure to be clamped in the clamping position, and the conductive clamping pieces 211 can be clamped in the clamping groove 311 under the action of the elastic conductive elements 231, so that the movable contact 31 can be clamped. In addition, in order to make the matching between the card slot 311 and each conductive card 211 more reliable, as shown in fig. 5, two ends of the card slot 311 may be concave arc structures adapted to the convex arc surfaces at two ends of the conductive card 211, so that each conductive card 211 can be completely engaged with the card slot 311 after being clamped into the card slot 311.
It will be understood by those skilled in the art that the foregoing embodiments are specific examples of the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in its practical application.
