The transformer dual-hugging rod thread jointing clamp is characterized in that: one end of the through hole of the fastening convex lug is provided with a counter bore, in which a fixing nut can be arranged in an engaged manner. The transformer dual-hugging rod thread jointing clamp has the following advantages that: when in installation, the nut is arranged in the counter bore at one end of the through hole of the fastening convex lug, only one wrench is needed to fasten the bolt, and the nut does not need to be clamped by the wrench, therefore, the installation and the operation are greatly convenient; the convex lug is fastened in an integratedmanner, therefore, the structure is simplified, and the production is convenient; and the two wire fixing pieces save material, therefore, the product cost is reduced.
Description
Technical field
The utility model relates to a kind of convenient transformer two-restriction pole screw thread binding clip of installing, and is used for high-voltage line and low-voltage line and the bushing of transformer and being connected of low-tension bushing end.
Background technology
Prior art is provided with the pole thread head at an end of a terminal block, is provided with the gap in the end of this pole thread head, respectively is provided with two relative fastening lugs on the both sides in this gap, is provided with through hole in each central authorities to this fastening lug; The other end at described terminal block is provided with horizontal solidus sheet, and the two ends of this solidus sheet respectively and be fixed by bolts on the described terminal block are provided with groove opposite in the central authorities of this solidus sheet and terminal block.It is fastening that through hole on the pole thread head fastening lug of this terminal block passes bolts and nuts when mounted, and nuts and bolt all needs to use spanner, otherwise one of them will rotate, and do not reach fastening purpose, inconvenient operation; Two other relative fastening lug has increased difficulty of processing when producing; Be provided with three solidus sheets and also there is no need, and increase material cost.
Summary of the invention
The purpose of this utility model just provides a kind of convenient transformer two-restriction pole screw thread binding clip of installing, and increases the problem that difficulty of processing, three solidus sheets increase material costs to solve installation inconvenience, fastening lug that prior art exists when producing.
The technical solution of the utility model is: the end at a terminal block is provided with the pole thread head, is provided with the gap in the end of this pole thread head, respectively is provided with relative fastening lug on the both sides in this gap, is provided with through hole on this fastening lug; The other end at described terminal block is provided with horizontal solidus sheet, the two ends of this solidus sheet respectively and be fixed by bolts on the described terminal block, central authorities at this solidus sheet and terminal block are provided with groove opposite, it is characterized in that: the end at the through hole of described fastening lug is provided with the counterbore that can insert hold-down nut identically.
Described fastening lug is as a whole, is provided with two described through holes on this fastening lug, is equipped with described counterbore at an end of each through hole.
Around forming, made by aluminium by other parts outside the copper layer by the copper layer for the screw of described pole thread head.
Described terminal block is formed by connecting with bolt by one section or two sections.
Groove opposite inboard in described solidus sheet and terminal block central authorities is provided with anti-skidding line.
Described solidus sheet is provided with two, the space distance.
The utility model has the advantages that: when mounted, nut is inserted in the counterbore of through hole one end of fastening lug, only need get final product with a spanner fastening bolt, nut does not need spanner to block, and fitting operation is greatly convenient; An integral body simplifies the structure during fastening lug, convenient production; Practice shows that two solidus sheets are enough to satisfy the connection area and the fastness of lead, not only simplify the structure, and have also saved material, have reduced product cost.

Embodiment
Referring to Fig. 1～Fig. 5, the end that the structure that the utility model is used for the embodiment that bushing connects is included in a terminal block 4 is provided with pole thread head 1, be provided with gap 11 in the end of this pole thread head, respectively be provided with a relative fastening lug 2 on the both sides in this gap 11, on this a pair of fastening lug 2, be provided with the through hole at two intervals, pass bolt 3 during use.End at each through hole is provided with the counterbore 18 (coincide with the shape of nut, prevent that nut from rotating) that can insert hold-down nut identically.The other end at described terminal block 4 is provided with two horizontal solidus sheets 8, the two ends of this solidus sheet 8 also are fixed on the terminal block 4 with bolt 7 respectively, central authorities at this solidus sheet 8 and terminal block 4 are provided with groove opposite 9, and with the approximate round mouth of relative formation, clamping wire 12 in round mouth.Groove 9 inner surfaces at this solidus sheet 8 and terminal block 4 are provided with anti-skidding line, to improve connectivity robustness.
Referring to Fig. 6～Figure 10, the difference that the utility model is used for the embodiment that the structure of the embodiment that low-tension bushing connects is connected with above-mentioned bushing is that described terminal block is divided into two sections, form with another section 6 by one section 4, two sections terminal blocks are fixed together with bolt 5.It is that the spacing of low-tension bushing of transformer is less that terminal block is divided into two sections reason, when being installed, terminal block needs rotation, the entire length of terminal block just can not be installed greater than the spacing of low-tension bushing, so be divided into two sections, will have one section 4 of pole thread head 1 and again another section terminal block 6 is connected with 4 after installing.Other structures are identical with a last embodiment, repeat no more.
Around forming, make by aluminium by other parts of the terminal block outside copper layer 10 by copper layer 10 for the screw of pole thread head 1 of the present utility model, adopts casting method to make.
The utility model is when using, the screw of pole thread head 1 is screwed on the screw rod 13 of the bushing 15 (referring to Fig. 5) of transformer 16 or low-tension bushing 17 (referring to Figure 10), hold-down nut is inserted in the counterbore 18 of fastening lug 2 one sides, pass the other end of through hole also with screwing bolt with screw 3.Also can safety guard 14 be installed in the outside of this binding clip, functions such as that safety guard 14 has is anti-electricity-theft, protection against electric shock, waterproof and dustproof, snow defence frost.
