Description
Technical field
The utility model relates to ground joint fields, more particularly, to a kind of ground joint device of high leakproofness.
Background technique
Currently, the connector being grounded in harness is usually processed using the method that mechanical crimp or ultrasonic wave crimp, process
It is wrapped up afterwards using heat-shrink tube to provide seal protection.
Since the copper wire volume of ground joint is big, number of share of stock is more, and copper tip head the widest part reaches 30mm, normal size heat-shrink tube face
Face the risk that set does not return into contracting；In addition heat when copper rapid heat dissipation, it is understood that there may be part can not completely pyrocondensation sealing risk.
In addition, the crimping bad phenomenon such as sharp dog-ear and burr is locally present in terminal head.Heating process, heat-shrink tube contraction are touched
To burr, and generate cracking.
At the harness end of copper terminal, since harness number of share of stock is more, attached 18 crimping lead wires in tail portion, common heat-shrink tube heating
Afterwards, glue amount is insufficient in managing, and can not flow between conducting wire completely, there are gas leakage risks.
Utility model content
The purpose of this utility model is exactly to provide a kind of high leakproofness to overcome the problems of the above-mentioned prior art
Ground joint device.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of ground joint device of high leakproofness, the device include that metal terminal, copper terminal, more of harness end are led
Line, for the metal terminal by the more open traverses in copper terminal connection wiring harness end, the device further includes adhesive tape, micelle and heat
The draw, at the exposure copper wire of copper terminal, the micelle is filled between the more open traverses in harness end the tape-stripping,
The shrinkable sleeve is on the more open traverses of copper terminal and harness end.
Preferably, the adhesive tape is duo-melt adhesive tape.
Preferably, the micelle is starlike press-melt micelle.
Preferably, the heat-shrink tube is the heat-shrink tube that diameter is 25mm~35mm.
It is highly preferred that the heat-shrink tube is the heat-shrink tube that diameter is 30mm.
Preferably, the heat-shrink tube is the cylindric heat-shrink tube that high power is shunk.
Compared with prior art, the utility model has the advantage that
1, use scope is wide: applicability is high, can be used in various big type joints.
2, leakproofness increases substantially: two kinds of encapsulating methods are used, the sealing performance at copper wire pressure joint had both been improved,
The sealing performance at harness is improved, so that the leakproofness of connector greatly improves.
3, it operates easy for installation simple: only need to paste a glue at copper wire when in use, one is put into inside harness
A starlike press-melt micelle.

Specific embodiment
The technical scheme in the embodiment of the utility model will be carried out clear, be fully described by, it is clear that described below
Embodiment is a part of the embodiment of the utility model, rather than whole embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work all should belong to this
The range of utility model protection.
As shown in Figs 1-4, the ground joint device of a kind of high leakproofness, the device include metal terminal 1, copper terminal 2,
The more open traverses 3 in harness end, the metal terminal 1 is by the more open traverses 3 in 2 connection wiring harness end of copper terminal, and the device is also
Including adhesive tape 4, micelle 5 and heat-shrink tube 6, the adhesive tape 4 is pasted at the exposure copper wire of copper terminal 2, and the micelle 5 is filled out
It is charged between the more open traverses 3 in harness end, described 6 sets of heat-shrink tube on the more open traverses 3 of copper terminal 2 and harness end.
The adhesive tape 4 is duo-melt (two-sided hot melt) adhesive tape.The micelle 5 is starlike press-melt (pressure
It is molten) micelle.
The heat-shrink tube 6 is the heat-shrink tube that diameter is 25mm~35mm.It is highly preferred that the heat-shrink tube 6 is diameter
For the heat-shrink tube of 30mm.The heat-shrink tube 6 is the cylindric heat-shrink tube that high power is shunk, and high power is shunk can receive for 5-10 times
Contracting.
The specific works of the utility model the following steps are included:
One piece of adhesive tape 4 is pasted at the exposure copper wire of copper terminal 2 by step 1, guarantees that copper wire is completely covered；
Micelle 5 is filled between the more open traverses 3 in harness end by step 2, and wrapped in wire is made to live micelle；
Step 3, the heat-shrink tube 6 shunk using diameter 25mm~35mm, high power, by it from harness end cap to terminal,
0.7bar pressure under conditions of specified, 15s heating, micelle melt, go deep between harness completely；
Step 4, pyrocondensation are completed, and finished product is obtained, the test of being sealed property.
The principles of the present invention: the utility model is intended to by improving the two-part leakproofness of connector to improve connector
The whole sealing performance with heat-shrink tube.
At the duo-melt tape-stripping to terminal compression joint, can by copper wire crimping burr and sharp dog-ear it is complete
Complete hiding avoids heat-shrink tube from contacting with the direct of copper wire burr wedge angle inside adhesive tape, thus play the role of protecting heat-shrink tube,
The leakproofness of copper wire pressure joint is improved, and there is positioning glue effect.
The starlike press-melt micelle is being under normal conditions solid-state, puts it into copper wire harness end.In heat-shrink tube heat
When contracting, heat-shrink tube generates biggish pressure to copper wire harness and press-melt micelle therein, in addition high temperature when pyrocondensation,
It is penetrated into copper wire harness so that press-melt micelle melts completely, more difficult is diffused into copper wire line so as to improve the glue of heat-shrink tube
The phenomenon that beam, has glue effect, improves the leakproofness at copper wire harness end.
The heat-shrink tube heat-shrink tube more excellent using performance, size is bigger, and energy tight completely lives connector；Pyrocondensation
Property is stronger, and the pressing force of butt joint is bigger, and sealability is stronger.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can be readily occurred in various
Equivalent modifications or substitutions, these modifications or substitutions should be covered within the scope of the utility model.Therefore, this is practical
Novel protection scope should be subject to the protection scope in claims.
