Background technology
Current electric power system, especially electrical network is to future developments such as ultra high voltage, intellectuality, green energy conservations, " connection " of electric power is important step: the link that " connection " is link the weakest on circuit and the most easily breaks down, and " connection " is also the most important link of line loss.Wideling popularize especially along with alloy cable, the connection (copper-aluminium transition) of alloy cable and power equipment highlights important.
The copper-aluminium transition splicing ear that current copper-aluminium transition splicing ear generally adopts copper and aluminium to be welded, and there is intrinsic defect in the welding of copper, aluminium, as: copper aluminium electro-chemical reaction, the copper aluminothermy coefficient of expansion are inconsistent, cause traditional copper-aluminum transition terminal loss greatly and easily blow.In addition, current copper-aluminium transition splicing ear adopts the mode of crimping mostly with the connection of wire, heavy crimping tool is needed wire and terminal compression joint to be fixed, install very inconvenient, and because installation personnel individual factor, different setter strength is different, causes wire and terminal compression joint place to there will be degree of tightness inconsistent.Alloy mechanical terminal current in addition and the connecting hole of electrical apparatus interstar connection post are single hole, connect unreliable and narrow application range.
Utility model content
The purpose of this utility model is to provide a kind of stable connection reliable and the alloy mechanical terminal with versatility, and realizing a kind of terminal can connect from the binding post of different power equipment, ensures that power equipment is connected with the safe transition of wire.
The utility model discloses a kind of alloy mechanical terminal connecting power equipment binding post, the terminal handle comprising conductor connecting pipe and be connected with power equipment binding post, both are the alloy cast forging piece of length direction center line altogether.Terminal handle offers two connecting holes, one of them connecting hole is slotted hole, and another connecting hole is circular hole.
Described two connecting holes are positioned on the length direction center line of described terminal handle, and the length direction of slotted hole is arranged along the length direction center line of terminal handle.
Described slotted hole is positioned at the nearly conductor connecting pipe end of described terminal handle.
Described conductor connecting pipe is hollow circular-tube, and its nearly described terminal handle end is blind end, its tube wall has at least one internal thread hole, and supporting in internal thread hole have corresponding torque nut.
The tube wall of described conductor connecting pipe there is the internal thread hole of two not concentrically lines, all supporting corresponding torque nut in two internal thread holes.
The width of described terminal handle is greater than the diameter of described conductor connecting pipe.
Rounding off between described terminal handle and conductor connecting pipe, the outer end of terminal handle is arc end, and the outer rim of conductor connecting pipe and each outer rim of terminal handle are all repaiied as arc-shaped edges.
This alloy mechanical terminal bodies carries out electroplating surfaces with tin process after adopting aluminum alloy materials to make, and makes its oxidation resistance strong, the copper aluminium electro-chemical reaction in avoiding the copper-aluminium transition of prior art to connect.
The utility model is alloy monolithic cast member, its terminal handle be connected with power equipment binding post is offered a circular hole and a slotted hole two connecting holes, when terminal is connected panel with the diapsid of power equipment binding post, first by through circular hole on terminal handle and the screw rod being connected the inner circular hole of panel by terminal handle be connected panel and fix, because the longer dimension on slotted hole long axis direction can be coupled to second circular hole on installation panel automatically, second screw rod is very successfully in place, make the diapsid installation panel close contact of terminal handle and power equipment, thus make the installation of terminal more solid and reliable.Namely the slotted hole on terminal handle can regulate the pitch-row of two circular holes on different power equipment diapsid connection panel poor, thus ensures the versatility of terminal.
Do not need to make the connection of wire and terminal to adopt heavy crimping tool, the tube wall of conductor connecting pipe offers internal thread hole, wire is compressed by torque nut supporting in internal thread hole, constant pressure, guarantee good electrical connection and non-damage wires, also not by the impact of operator's human factor, elasticity is consistent, makes the connection of wire and terminal more convenient and accurately put in place.
Burning out conductor connecting pipe because electric current is excessive during in order to prevent through-flow, is the diameter being greater than conductor connecting pipe by the width design of terminal handle.
In order to avoid electric current flashover and chattering, rounding off between the terminal handle of terminal and conductor connecting pipe, the outer end of terminal handle is arc end, and the outer rim of conductor connecting pipe and each outer rim of terminal handle are all repaiied as arc-shaped edges.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1, present embodiment discloses a kind of alloy mechanical terminal connecting power equipment binding post, comprise conductor connecting pipe 1 and terminal handle 2, both are the alloy cast forging piece of length direction center line altogether, and the width of terminal handle 2 is greater than the diameter of conductor connecting pipe 1.Terminal handle 2 offers two connecting holes, wherein the connecting hole of nearly conductor connecting pipe 1 end is slotted hole 21, and another connecting hole is circular hole 22.Two connecting holes are positioned on the length direction center line of terminal handle 2, and the length direction of slotted hole 21 is arranged along the length direction center line of terminal handle 2.Conductor connecting pipe 1 is hollow circular-tube, and its near-end handle 2 end is blind end, and its tube wall has all supporting corresponding torque nut 3 in internal thread hole 11, two internal thread holes 11 of two not concentrically lines.
