Take out groove in matched side.The present invention takes out the cooperation of groove by anticreep protrusion and side, so that CPA connector is inserted into rear side
When, anticreep protrusion is caught in side and takes out in groove, prevents CPA connector from excessively inserting afterwards.
Antiskid lock is equipped between the tail portion of the snap-gauge, the two sides of the antiskid lock tail portion are rotated by torsional spring and snap-gauge
Connection, the middle part of the antiskid lock are equipped with 2 guide grooves, and under non-force state, the antiskid lock is oblique from its tail portion to head
Upper setting.
The upper surface of the clamping portion is equipped with 2 and matches guide protrusions with guide groove, the length of the guide protrusions
Direction is parallel with side rib, and when anticreep protrusion is fastened on side and takes out in groove, the apical head of guide protrusions is connected to antiskid lock
Tail portion.When CPA connector is gradually inserted back into cutting ferrule ontology, guide protrusions are moved along guide groove, and are gradually opened anti-
Sliding lock, antiskid lock be gradually transformed into from setting obliquely it is horizontally disposed, until two guide protrusions when being pierced by from guide groove, are prevented
Sliding lock becomes to be arranged obliquely under the action of torsional spring from newly, so that the front end with guide protrusions abuts.Do not opening antiskid lock
In the case where, entire CPA connector can not move forward.At this point, entire CPA connector can not both move forward, also without normal direction
After move, that is, be fixed in sheath ontology.
The clamping portion includes the fixed part of periphery and the movable part of centre, and the movable part is set with fixed integrally
Set, and between movable part and fixed part between three sides there are gap, the two sides of the movable part are flushed with two guide protrusions,
The bottom of movable part is arranged in the up-side down triangle protrusion.The setting is so that movable part has certain performance sprung up and down.
The clamping portion and head junction are equipped with ribs.
A kind of Wiring harness connector equipped with CPA connector as described above, which includes jack body and sheath
Ontology, the jack body are inserted into sheath ontology, and a trapezoidal protrusion is equipped in the sheath ontology, is set in the middle part of jack body
Have a baffle, after jack body and sheath ontology are installed, the baffle be located at the front end of trapezoidal protrusion and with it is trapezoidal
The abutting of protrusion, after the CPA connector is inserted into sheath ontology, the up-side down triangle protrusion be located at trapezoidal raised rear end and with
Trapezoidal protrusion abuts.Such setting forms secondary lock, and due to the presence of baffle, entire sheath ontology can not be moved forward,
And after CPA connector is inserted into sheath ontology, not only with sheath ontology is fixed completes, but also up-side down triangle protrusion also abut it is trapezoidal
The rear end of protrusion, so that sheath ontology can not move backward, secondary lock comes into force.
The front end of the trapezoidal protrusion is complementary with the rear end of baffle；The rear end of the trapezoidal protrusion and up-side down triangle protrusion
Front end is complementary.
