Background

At present, in a power system, especially a power grid, develops towards ultra-high voltage, intellectualization, green energy conservation and the like, the connection of the power is an important link, the connection is a link in which the weakest link on a circuit is most prone to failure, and the connection is also the most important link of line loss.

The terminals of the current power equipment connected with the conducting wire comprise a single-hole terminal and a double-hole terminal. The single-hole terminal is matched with equipment with a single-hole connecting plate, and the double-hole terminal is matched with equipment with a double-hole connecting plate; the pitch of the holes between most two holes of the traditional double-hole terminal is fixed, and the pitch of the double-hole holes of connecting plates of different power equipment is different, so that the type selection of the terminal is difficult, and the inventory of users is increased.

Two types of current double-hole terminals with adjustable hole pitches are provided, wherein one type is that a round hole is arranged at the front end of an equipment connecting end, and a strip-shaped adjusting hole is arranged at one end close to a cable connecting part; the other is just the opposite, namely the sliver adjustment hole is at the front end of the equipment connection part.

Both of these have disadvantages: when the cable is connected with an equipment terminal, if the former is short in the power equipment terminal 8, the elongated hole of the equipment terminal can be partially suspended, as shown in fig. 1, under the condition of large current, the current-carrying capacity borne by two sides of the suspended elongated hole is limited, the terminal is likely to be blown, and generally, an aluminum core cable has no problem, but if the cable is connected with a copper core cable with the largest cross section which can be met by the type, the suspended part can hardly meet the current-carrying capacity requirement, and unless the part is made wide enough or thick enough, the product cost can be greatly increased; widening also reduces the safe distance of the line and even makes certain equipment impossible to install; although the latter solves the problem of 'suspension', the wire clamp is often too long due to the long strip adjusting hole because the round bolt crimping hole is close to the conductor connecting end, and the terminal cannot be installed due to interference when a front blocking body is encountered.

SUMMERY OF THE UTILITY MODEL

Meanwhile, one mounting bolt is omitted, the alloy terminal and the power equipment terminal can be fixedly connected by only one bolt, and the mounting convenience is greatly improved.

As a further improvement of the technical scheme, the positioning columns are vertically arranged downwards and are located at the bottom of the connecting end of the equipment.

The beneficial effect of the improvement is as follows: the installation convenience is further improved, and when the alloy terminal is only required to be placed in the installation hole on the power equipment terminal from top to bottom, the positioning column can be inserted into the installation hole for positioning and fixing.

As a further improvement of the above technical solution, the front end of the equipment connecting end is provided with an end part; the positioning column is arranged on the end part.

The beneficial effect of the improvement is as follows: one section of equipment link front end reservation becomes the tip, the installation of the reference column of being convenient for.

As a further improvement of the technical scheme, chamfers are arranged on two sides of the end part.

The beneficial effect of the improvement is as follows: the volume of this alloy terminal can further be dwindled, the installation of this alloy terminal of being convenient for more, simultaneously reduce cost.

As a further improvement of the technical scheme, the end of the positioning column is hemispherical or conical.

The beneficial effect of the improvement is as follows: the positioning column can be conveniently positioned and inserted into the mounting hole.

As a further improvement of the technical scheme, the positioning column is detachably fixed on the equipment connecting end through threaded connection.

The beneficial effect of the improvement is as follows: the reference column directly adopts the independent structure, and the upper end has the screw thread, through threaded connection direct mount on equipment link, can further reduce the cost of integrated into one piece processing, simultaneously can be more nimble need change different length or the reference column of size more.
