Stopping surface 215, plug casing stopping surface 215 can prevent the locking sleeve spring being arranged between lock sleeve 22 and procapsid 211
25 are overly compressed.
The length of plug casing 21 of the invention is standard value, and components when use in plug casing 21 can be used
Standard component.Compared with existing standard socket 1, it is seal section that the length and its standard value of lock sleeve 22 of the invention, which obtain difference,
223 length, that is to say, that the length of lock sleeve 22 of the invention is less than its corresponding standard value, and the length of lock sleeve 22
Difference with the length of the lock sleeve of the plug of standard is the length of seal section 223, plug casing stopping surface 215 and plug casing
The distance between 21 rear end face is equal to the length of seal section 223 less than the difference of its corresponding standard value and the two.This hair
Bright fluid connector realizes the close of lock sleeve 22 and plug casing 21 by increasing seal section 223 in the rear end of lock sleeve 22
Envelope, while by moving back plug casing stopping surface 215, reduce between plug casing stopping surface 215 and 21 rear end face of plug casing
Distance, do not change the size inside plug casing 21 while not increasing by 2 length of plug so that plug 2 of the invention with
Existing standard socket can be used interchangeably.Compared to existing standard plug, the procapsid of the plug casing 21 in the present embodiment
211 be screwed segment length while meeting bonding strength less than the full-length of standard plug.
Back casing 212 is equipped with the back casing stopping surface 216 cooperated with 211 rear end face block of procapsid, back casing block
Face 216 can play the role of positioning procapsid 211, and the back casing stopping surface 216 in the present embodiment is apart from plug casing 21
The distance between rear end face is less than its corresponding standard value, in the present embodiment, by the section that is screwed for reducing standard plug 2
Length, while reducing the distance between back casing stopping surface 216 and 21 rear end face of plug casing, realize 21 length of plug casing not
On the basis of increased, lock sleeve 22 can be sealed with plug casing 21 to be cooperated.
Plug described in the specific embodiment of the specific embodiment of plug of the invention, plug and above-mentioned fluid connector
Structure it is identical, do not repeating.
The specific embodiment of plug casing component of the invention, including plug casing and lock sleeve, plug casing and locking
The structure of set is identical as the structure of plug casing described in the specific embodiment of above-mentioned fluid connector, lock sleeve, not superfluous
It states.
In the other embodiments of fluid connector and its plug, plug casing component of the invention, above-mentioned latch segment can be with
It is other locking members such as lock ball；The length of plug casing can also extend, but not change the structure inside Socket casing；It is above-mentioned
Lock sleeve can also be with plug casing and snap connection.
