Fig. 7 show the sectional view of the self-locking device installment state of Fig. 1, please also refer to Fig. 7.Self-locking device 19 is contained in self-locking
It is used for controlling dismounting in receiving portion 39 and inserts pipe 11, be i.e. used for limiting insertion pipe and move.Self-locking device 19 includes two position limit arms
191, elastic bend part 193.Two position limit arms 191 are fixed on the end of elastic bend part 193.
Position limit arm 191 is rod-like structure, in order to preferably utilize the space position limit arm of self-locking receiving portion 39 for arc or to connect
The fold-line-shaped rod member of nearly arc.The quantity of position limit arm 191 is two, and the side towards another position limit arm 191 of position limit arm 191 is solid
Determine limited location projection 191h.The one side towards insertion pipe 11 of spacing preiection 191h is curved surface or inclined-plane, so can make insertion
What pipe 11 was more prone to is inserted into receiving terminal 13.The side of the side inserting pipe 11 dorsad of spacing preiection 191h is for being perpendicular to insert
Enter the plane of pipe 11 axis.The side towards another spacing preiection 191h of spacing preiection 191h is cambered surface, the diameter of this cambered surface
Close or equal to the external diameter inserting pipe 11 appropriate section.So can preferably limit the movement inserting pipe 11.Position limit arm 191 with
The direction inserting pipe 11 axis between receiving terminal 13 dorsad has space, i.e. position limit arm 191 has sky with being connected between wall 399
Gap.
Outside dorsad in the middle part of two position limit arms 191 is fixed with the first Anti-fall projection 191a, the phase of two position limit arm 191 ends
The second Anti-fall projection 191b it is fixed with to inner side.
Elastic bend part 193 is rectangle for its cross section of arc platy structure, and elastic bend part 193 has certain bullet
Property, i.e. elastic bend part 193 has stress deformation, releases stress and rely on the property of state before himself spring return stress
Energy.It is the platy structure protruded that elastic bend part 193 inserts pipe 11 axis dorsad.Elastic bend part 193 and the company of position limit arm 191
Meeting place, the inner side in opposite directions of position limit arm 191 is fixed with moving part 193c, and moving part 193c is near the side of position limit arm separated part 397
For inclined-plane, when this inclined-plane mutually extrudes near the surface of moving part 193c with position limit arm separated part 397, two position limit arms 191 are carried on the back
To movement.
Elastic bend part 193 and position limit arm 191 alternative one can be fixed in other embodiments of the invention.
The cross section of elastic bend part 193 is square, circular, triangle, rhombus, polygon in other embodiments of the invention
Shape, abnormity etc., the cross sectional shape of elastic bend part 193 can change.
Refer to Fig. 2, insert pipe 11 during the connection status of dismountable plug-in connector of the present embodiment and insert and receive
End 13 is internal；Interior O ring 171, shading ring 173, outer O ring 175, outer back-up ring 177 is successively from inserting pipe 11 dorsad to inserting pipe 11
Direction arranges.It should be noted that the diameter of outer O ring 175 is more than the insertion of receiving terminal 13 with relevant position due to interior O ring 171
The gap of pipe 11, now interior O ring 171, is formed between outer O ring 175 and smooth insertion pipe 11 outer surface, receiving terminal 13 inner surface
Certain pressure, result in formation of extraordinary sealing effectiveness.The outer retainer ring spacing portion 177e of outer back-up ring 177 coordinates with outer back-up ring
Portion 137e coordinates the position realizing outer back-up ring 177 to fix.Lock fit portion 11h and spacing preiection 191h coordinates realization to insert pipe
Position is fixed.
Fig. 8 show the partial enlarged drawing of the moving part of Fig. 7.Refer to Fig. 7,8, insert receiving terminal 13 at self-locking device 19
During:
The surface that first Anti-fall projection 191a contacts with connecting portion 399 is to guide the first Anti-fall projection 191a to insert
Inclined-plane；The surface that second Anti-fall projection 191b contacts with position limit arm limiting section 395, position limit arm separated part 397, connecting portion 399
For the cambered surface guiding the second Anti-fall projection 191b to insert；Spacing preiection 191h connects with connecting portion 399, position limit arm separated part 397
The surface of the both sides touched is the inclined-plane guiding spacing preiection 191h to insert.
The surface that moving part 193c contacts with position limit arm separated part 397 flattens for guiding elastic bend part 193, two position limit arms
191 inclined-planes moved dorsad.
Being formed between position limit arm limiting section 395, position limit arm separated part 397 and connecting portion 399 can be through position limit arm 191
Through hole.
Having space between position limit arm 191 and connecting portion 399, this space is for making two position limit arms 191 have enough
It is spatially separating, makes insertion pipe 11 can extract in receiving terminal 13.
In order to obtain more preferable Anti-fall effect, the surface towards position limit arm limiting section 395 of the first fitting projection 139a
Fit with the surface towards elastic bend part 193 of the first Anti-fall projection 191a；The position limit arm dorsad of position limit arm limiting section 395
The position limit arm limiting section lower surface 139b of limiting section 395 and the table towards elastic bend part 193 of the second Anti-fall projection 191b
Fit in face.
In order to prevent self-locking device 19 by the possibility of accidental pressure, after self-locking device 19 is entirely enclosed in receiving terminal 13, self-locking device
19 are perpendicular to insert the cross sections of pipe 11 axis, less than or equal to inwall, outer wall vertical in inserting the cross section of pipe 11 axis, and interior
Wall, outer wall block.
In order to obtain more preferable position limit arm separating effect, the surface towards elastic bend part 193 of position limit arm separated part 397
Surface laminating with the elastic bend part dorsad 193 of moving part 193c.
When self-locking device 19 fully-inserted receiving terminal 13, elastic bend part 193 and position limit arm separated part 397 have makes elasticity
The space that bending section 193 flattens.The length along insertion pipe 11 axis direction of elastic bend part 193 can be more than position limit arm 191
Along insert pipe 11 axis direction length.Elastic bend part 193 can have bigger press surface.
When self-locking device 19 inserts receiving terminal 13, first position limit arm 191 insert connect wall 399 and inwall 393, outer wall 391 it
Between formed socket i.e. installation.It is of course possible to can finally install self-locking device 19 in installation process.
Self-locking device 19 insert receiving terminal 13 after the second Anti-fall projection 191b to be positioned at position limit arm limiting section 395 the most elastic curved
In the groove that the surface of pars convoluta 193 and inwall, outer wall are formed, thus can separate by separating the second Anti-fall projection 191b
Position limit arm 191.
Inserting insertion guide portion 113 when pipe 11 inserts makes insertion pipe 11 be very easy to be put into receiving terminal 13.Spacing
Protruding 191h is curved surface or the inclined-plane with guiding function towards the face of lock fit portion 11h, and therefore spacing preiection 191h is permissible
It is relatively easy to realize spacing by lock fit portion 11h.In order to realizing of being more prone to is spacing, lock fit portion 11h's
Be arranged to inclined-plane or curved surface towards the face of spacing preiection 191h, i.e. the diameter of lock fit portion 11h is towards the side of spacing preiection 191h
To reduction.
When the direction pressing elastic bend part 193 inserted along self-locking device 19, moving part 193c and position limit arm separated part
397 contacts, the two pressure each other guides elastic bend part 193 to flatten, and two position limit arms 191 move dorsad.Elastic bending
Portion 193 gradually flattens, i.e. the spacing of two position limit arms 191 is gradually increased along with elastic bend part 193 gradually flattens.At this moment two
Position limit arm 191 the most fully opens, and i.e. can extract insertion pipe 11.
