Abstract
The utility model discloses an excessive ammeter contact pin of copper aluminium, including crimping pipe and contact pin end, the crimping pipe is aluminium system, the contact pin end is the copper, crimping pipe and contact pin end friction weld are formed with the changeover portion, the crimping pipe is cylindrical and crimping pipe and keeps away from the one end of contact pin end and be formed with the inner chamber, the inner chamber is round hole shape, the contact pin end is relative both sides cylindrical and the contact pin end and is the platykurtic, the changeover portion is round platform shape, the crimping pipe has the wall thickness degree of the one end of inner chamber to be more than or equal to 3.5mm.
Description
Technical field
The utility model relates to a kind of binding post, is specifically related to a kind of binding post being applicable to low tension meter terminal and connecting.
Background technology
When current ammeter is connected with outer lead, that the line end of outer lead is inserted ammeter terminal box connects in electric jack, then conductor wire end crimping is completed electrical connection, and wire is directly connected with ammeter and easily the overheated situation causing ammeter to burn occurs; People have employed binding post and are electrically connected for this reason, but can loosen because of binding post or cause loose contact not with ammeter contact area, so that heating of contact and damage ammeter, affect electric power transfer.
Summary of the invention
The purpose of this utility model is to provide a kind of excessive ammeter contact pin of copper aluminium being applicable to wire and being connected with ammeter terminal
For achieving the above object, the utility model adopts following technical scheme: the excessive ammeter contact pin of a kind of copper aluminium, comprise aluminium hydraulic pressed connecting pipe and contact pin end, described aluminium hydraulic pressed connecting pipe is aluminum, described contact pin end is copper, described aluminium hydraulic pressed connecting pipe and the friction welding of contact pin end are also formed with changeover portion, cylindrical and the aluminium hydraulic pressed connecting pipe of described aluminium hydraulic pressed connecting pipe away from contact pin end one end be formed with inner chamber, described inner chamber is circle hole shape, described contact pin end is cylindrical and the relative both sides of contact pin end are flat, described changeover portion is truncated cone-shaped, described aluminium hydraulic pressed connecting pipe has the pipe thickness of one end of inner chamber to be more than or equal to 3.5mm.
During use, wire is pressed in the inner chamber of aluminium hydraulic pressed connecting pipe by hydraulic means etc., the contact pin end of aluminium hydraulic pressed connecting pipe front end is inserted connecing in electric jack and can completing electrical connection of ammeter terminal box.The difference connecing electric jack size and wire voltage size of different ammeters can select the excessive ammeter contact pin of the copper aluminium of different size.Adopt line ball mode to be connected with wire, while not damage wires, define enough large extruding force to wire, reliably, locking anti seismic efficiency enhancing, prevents wire to loosen impact on electric power transfer in contact; The relative both sides of contact pin end are flat, and the contact area of pressing from both sides with the wiring hole of ammeter increases, and are more easily stepped up by the wiring hole of ammeter folder compared with cylindrical, prevent the negative effect because contact area causes not; Adopt the mode of friction welding that aluminium hydraulic pressed connecting pipe can be made to be connected with contact pin end tightr, and use the requirement of this welding manner to welder less, welding fast and flexible is stablized, and can not impact environment; Changeover portion is that truncated cone-shaped can form position-limiting action to the connection jaws of ammeter, and the side of the small size of truncated cone-shaped is contact pin end, and the large-area side of truncated cone-shaped is aluminium hydraulic pressed connecting pipe; The pipe thickness of aluminium hydraulic pressed connecting pipe, at more than 3.5mm, can extend useful life of the present utility model.
As preferably, the both side surface in flat of described contact pin end is formed with contact pin end travers.Above-mentioned setting can increase the contact area that contact pin end and ammeter string holes are pressed from both sides.
As preferably, described contact pin end travers are that vertical interval is arranged.Above-mentioned setting can increase the contact area that contact pin end and ammeter string holes are pressed from both sides.
As preferably, described contact pin end travers are that vertical uniform intervals is arranged.Above-mentioned setting can increase the contact area that contact pin end and ammeter string holes are pressed from both sides.
As preferably, the length of described contact pin end travers is identical with the length of contact pin end.Above-mentioned setting can increase the contact area that contact pin end and ammeter string holes are pressed from both sides.
As preferably, the outer wall of described aluminium hydraulic pressed connecting pipe is formed with aluminium hydraulic pressed connecting pipe travers.Above-mentioned setting can increasing friction force, is convenient for people to the utility model to be inserted in ammeter string holes.
The utility model has the generation that can prevent because wire or binding post loosen, the ammeter that causes not with ammeter contact area damages, affects the problem of circuit transmission, and the advantages such as easy to use, long service life.
