Core 80 is fixedly connected, and with respect to the sliding slot passed through for the bolt 60 is equipped on the outer expanding sheath 50, the bolt 60 exists
It is slided up and down in the sliding slot.
Further, one end of the slide core 80 is equipped with boss, described when the assembly tool 100 is in original state
Elastic component 90 is in elongation state, when the slide core 80 slides down to extreme position, the boss and 30 phase of retainer
It supports.
Further, the elastic component 90 is compressed spring.
Since 90 most of the time of elastic component is in compressive state, by the way that elastic component 90 is designed as compressed spring,
It is able to extend its physical life.
It is understood that besides compression springs, the elastic component 90 can also be extension spring, gas spring etc.
Other interchangeable components.
The present invention provides a kind of assembly methods for outer O-ring, include the following steps；
Using the assembly tool, outer O-ring 200 is sheathed on the outer end of slide core 80 and outer end phase with outer expanding sheath 50
It supports, the outer end of slide core 80 relatively and is abutted with adapter piece 300, is pushed, when the slide core 80 is for being arranged outer O-ring 200
When one end and adapter piece 300 offset and continue to push against, the slide core 80 presses to elastic component 90 and retracts into the sliding sleeve 20,
The outer expanding sheath 50 promotes outer O-ring 200 in installation to band taper adapter piece 300.The assembly method is easy to operate, worker
It is time saving and energy saving to install, and one-time-reach-place, solid and reliable.
Concrete operating principle and application method of the invention are as follows: the assembly tool 100 is under initial free state, due to bullet
Property part 90 effect, shift slide core 80 onto lower limit, outer 50 head of expanding sheath is exposed on the head of slide core 80.Phantom ring 70 and slide core
80 is integral with the fixation of bolt 60.Phantom ring 70 is also in bottom by outer 50 tightening state of expanding sheath.Due to slide core when feeding
80 diameter is bigger than the internal diameter of outer O-ring 200, and covering will not fall down in slide core 80, to realize outer O-ring 200
Crawl.
Work as slide core 80 in the assembly tool 100 and be moved to upper end of joint face, continues during moving down, phantom ring
70 slack remaining parts and outer O-ring 200 are continued under the action of thrust when touching connector together with slide core 80 it is past
Lower movement.Outer O-ring 200 is slowly opened with outer expanding sheath 50 along connector outer rim, and outer expanding sheath 50 can push outer O-ring always
200 move forward.Finally after servo is mobile or limit is mobile, outer O-ring 200 is shifted onto specified card slot.When the dress
During leaving adapter piece 300 with tool 100.Elastic component 90 pushes slide core 80 and phantom ring 70 is moved down outer expanding sheath
50 collapse, and make the life of outer expanding sheath 50.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the present invention in any form；It is all
The those of ordinary skill of the industry can be shown in by specification attached drawing and described above and swimmingly implement the present invention；But it is all
Those skilled in the art without departing from the scope of the present invention, are done using disclosed above technology contents
The equivalent variations of a little variation, modification and evolution out is equivalent embodiment of the invention；Meanwhile it is all according to the present invention
The variation, modification and evolution etc. of substantial technological any equivalent variations to the above embodiments, still fall within skill of the invention
Within the protection scope of art scheme.
