By adopting technique scheme, this isolating switch is when wiring, first by coordinating a baffle plate assembly on the slot of terminal block, baffle plate assembly inserts from the side, then the baffle plate on butterfly assembly also makes it prop up, hold-down bolt, so just can separate the hand that releasing one must prop up bolt, clamping just becomes simple, convenient, and without the need to considering that the situation selecting hook bolt to drop when nut occurs, without the need to repeatedly screwing back and forth in clamp process, save time, labour-saving ensure that the stable of wiring simultaneously, equally owing to being be slidably matched between baffle plate assembly and terminal block, can be applicable to again other need on clamp isolating switch when splitting out baffle plate assembly after clamp completes, wide adaptability.
The utility model is set to further: described slot is in " L " shape, and described fixed head comprises limiting section and " U " type Plug Division, and described " U " type Plug Division and slot are slidably matched, and described limiting section is arranged on the opposite side of terminal block opposing nut.
By adopting technique scheme, slot carries out spacing in arranging of " L " shape to the vertical direction of baffle plate assembly, avoid baffle plate assembly coming off at vertical direction, coordinating between fixed head with slot is guaranteed in " U " type Plug Division, the baffle plate that is set to of limiting section improves support, guarantees the restriction of baffle plate to bolt.
The utility model is set to further: described limiting section is fixed with column, and described baffle plate comprises the arc contact part that is wholely set and is enclosed within rotating part on column, and described column is between adjacent two bolt assemblies.
By adopting technique scheme, baffle plate realizes rotating by being enclosed within rotating part on column, by arc contact part, bolt is limited, arc contact part can also adapt to bolt not of uniform size, improve the adaptability of baffle plate assembly, column is positioned at the setting of adjacent two bolt assemblies when after one of them bolt of post completes clamp, screws out baffle plate and is placed in below another bolt and carry out clamp work.
