Abstract
One kind, which rises, connects formula connector, including pipe and connector, the pipe is threaded onto the through-hole of the connector, through reaming processing, to form tab through-hole and the pipe in through-hole horn-like for one end of through-hole, and the pipe through reaming is located at the part of the pipe of the through-hole other end to be interference fitted on the through-hole wall of the connector described in being fixed on.The connector of the utility model eliminates pad, and reducing reduces the fraction defective scrapped because welding is unstable because solderless contact is without this procedure of hunting leak, and improves quality and yield, reduces manufacturing cost.
Description
Technical field
The utility model belongs to air conditioning for automobiles field of components, and especially rising with one kind, it is related to connect formula connector.
Background technique
The joint part of the existing tubing for applying to air conditioning for automobiles, metal alloy, it is varied with the type of attachment of pipe,
But joint tighness all exists certain bad, currently used structure type is as shown in Figure 1, joint style is by pipe
A1, solder A2, connector A3 composition, A1 and A3 mainly by A2 heating melt after be welded, in process to the temperature of heating,
Time, the material of the pressure, solder that heat gas source require very stringent, have a very high skill requirement to operative employee, in butt joint
Hole Vehicle Processing smoothness requirements are higher.However above scheme still has following defect: 1, after welding, the position A2 is easy to produce gas
Hole leads to not seal, influences performance.2, after welding, the position A2 is easy to produce rosin joint and dry joint, causes the position A2 to be broken, shadow
Ring performance.3, after welding, the position A1 and A3 is easy to produce burn and numb, causes A1 and portion faces damaged or fracture, causes
It can not seal, influence performance.4, air-tightness need to could be found by leak detection.
Utility model content
For great number of issues present in above-mentioned background technique, the utility model is intended to provide one kind and is easily worked, safety
Reliably rise and connects formula connector.
For this purpose, the utility model uses following technical scheme: one kind, which rises, connects formula connector, characterized in that including pipe and
Connector, the pipe are threaded onto the through-hole of the connector, and one end of through-hole makes tab through-hole through reaming processing and is located at
Pipe in through-hole forms horn-like, and the part that the pipe through reaming is located at the pipe of the through-hole other end is fixed on being interference fitted
On the through-hole wall of the connector.
As supplement to above-mentioned technical proposal and perfect, the utility model further includes following technical characteristic.
The connector is penetrated in the inner hole of the pipe by plug and carries out multiple ream forming.
The pipe is aluminum pipe.
The utility model can achieve following the utility model has the advantages that the connector of the utility model eliminates pad, reduce because
Solderless contact reduces the fraction defective scrapped because welding is unstable, improves quality and yield without this procedure of hunting leak,
Reduce manufacturing cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing connector.
Fig. 2 is the structural schematic diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing.
As shown in Fig. 2, the utility model pipe B1 passes through connector B2, matching for pipe and joints is combined into clearance fit at this time,
Then by tube grip on special equipment, by with the multiple reaming of plug, making one end of its through-hole make connector through reaming processing
Through-hole and the pipe in through-hole form horn-like, and the pipe through reaming is located at the part of the pipe of the through-hole other end with interference
Cooperation is fixed on the through-hole wall of the connector, and the position B3 is interference fit, so that reaching connector and aluminum pipe can closely connect
It connects.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
