Description
Technical field：
It the utility model is related to a kind of reactor copper aluminium press-contacting connection structure.
Background technology：
Copper aluminium press-contacting connection structure currently used for reactor generally comprises two kinds of forms, and one kind is direct compression joint type, separately
One kind is welded type.
Direct compression joint type includes aluminum steel and tin plating copper tip, and tin plating copper tip is a sleeve, and the tail end of aluminum steel is directly set
In sleeve, crimped with Crimping Pliers, the fastness so connected is poor, also, gap be present between aluminum steel and tin plating copper tip, tide
Wet air is easily advanced into gap, aluminum steel is produced electrochemical corrosion reaction with tin plating copper tip, is easily caused to send out
Heat burns out copper aluminium crimping structure；Welded type includes aluminum steel and tin plating copper tip, and tin plating copper tip is a sleeve, the tail end of aluminum steel
It is connected with tin plating copper tip by welding wire, so effectively increases the fastness of connection, but the seam of aluminum steel and tin plating copper tip
Gap is still existing all the time, and the presence in space between aluminum steel and tin plating copper tip can not be also avoided even if the upper filler of filling.
Utility model content：
The utility model provides a kind of reactor copper aluminium press-contacting connection structure, and this is reasonable in design, novel, using aluminium
Wire terminal and the threaded form of tin plating copper tip, the steadiness of connection is strong, and layers of copper is coated with aluminum wire connector, passes through layers of copper
It is excessive be connected with tin plating copper tip, effectively prevent and be directly connected between aluminum wire connector and tin plating copper tip, so as to effectively
Avoid between aluminum wire connector and tin plating copper tip and there is space, effectively prevent aluminum steel, aluminum wire connector with it is tin plating
Electrochemical corrosion reaction occurs between copper tip, so as to extend the service life of reactor copper aluminium press-contacting connection structure, is suitable to
Use is widely popularized, solves problems of the prior art.
The utility model is that technical scheme is used by solving above-mentioned technical problem：
A kind of reactor copper aluminium press-contacting connection structure, including aluminum steel and copper tip, the tail end of the aluminum steel are welded with a circle
The aluminum wire connector of column, is coated with layers of copper on the side surface and leading section surface of aluminum wire connector, in the side surface layers of copper of aluminum wire connector
Provided with screw thread；The copper tip is the cylindrical shape of one end closing, and the inwall of copper tip passes through screw thread phase with the outer wall of aluminum wire connector
Adaptation connection；The side surface and both ends surface of the copper tip are coated with tin layers.
The tail end of the aluminum steel has the plumb joint of bending l-shaped, and the length of plumb joint bending part is aluminum wire connector diameter
0.5-0.8 times.
The utility model uses said structure, and this is reasonable in design, novel, using aluminum wire connector and tin plating copper tip
Threaded form, the steadiness of connection is strong, and layers of copper is coated with aluminum wire connector, is connected by the excessive and tin plating copper tip of layers of copper
Connect, effectively prevent and be directly connected between aluminum wire connector and tin plating copper tip, so as to effectively prevent aluminum wire connector with it is tin plating
There is space between copper tip, effectively prevent and electrochemistry occurs between aluminum steel, aluminum wire connector and tin plating copper tip
Corrosion reaction, so as to extend the service life of reactor copper aluminium press-contacting connection structure, used suitable for being widely popularized, suitable for extensive
Promote the use of.
Brief description of the drawings：
Fig. 1 is cross-sectional view of the present utility model.
Fig. 2 is the cross-sectional view of the utility model aluminum wire connector.
Fig. 3 is the cross-sectional view of the utility model copper tip.
Fig. 4 is the structural representation of the utility model aluminum steel.
In figure, 1 aluminum steel, 2 copper tips, 3 aluminum wire connectors, 4 layers of copper, 5 screw threads, 6 tin layers, 7 plumb joints.
Embodiment：
For the technical characterstic for illustrating this programme can be understood, below by embodiment, and its accompanying drawing is combined, to this reality
It is described in detail with new.
As shown in figs. 1-4, a kind of reactor copper aluminium press-contacting connection structure, including aluminum steel 1 and copper tip 2, the aluminum steel 1
Tail end be welded with a columned aluminum wire connector 3, be coated with layers of copper 4, aluminum steel on the side surface and leading section surface of aluminum wire connector 3
The side surface layers of copper 4 of joint 3 is provided with screw thread 5；The cylindrical shape that the copper tip 2 is closed for one end, the inwall and aluminium of copper tip 2
The outer wall of wire terminal 3 is adapted connection by screw thread；The side surface and both ends surface of the copper tip 2 are coated with tin layers 6.
In order to increase the fastness connected between aluminum steel 1 and aluminum wire connector 3, increase and welded between aluminum steel 1 and aluminum wire connector 3
Bonding area, the tail end of the aluminum steel 1 has the plumb joint 7 of bending l-shaped, and the length of the bending part of plumb joint 7 connects for aluminum steel
0.5-0.8 times of first 3 diameter.
Using reactor copper aluminium press-contacting connection structure of the present utility model, during linked reactor copper aluminium press-contacting connection structure,
First aluminum steel 1 and the phase of aluminum wire connector 3 are welded, then, then aluminum wire connector 3 is threadedly coupled with the phase of copper tip 2, connection procedure is simple
Singly, conveniently, Joining Technology is simple, joint efficiency.
Above-mentioned embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
