During stop bit, the wedge structure 233 of clamp just supports terminal 4, plays the secondary self-locking action of TPA clamps 23.
A kind of installation method of service switch electric connector, comprises the following steps：1. assemble contact pin sheath assembly 1：It will insert
Pin 13 is inserted in contact pin sheath 11, and cpa card 12 is loaded into the inner side of self-locking cantilever 113；2. assemble socket jacket assembly 2：First will
TPA clamps 23 are assembled to TPA clamps prepackage position, after terminal 4 loads socket jacket 21, then TPA clamps are assembled into TPA clamps and locked
Stop bit；3. contact pin sheath assembly 1 is fitted into socket jacket assembly 2, it is pre- that contact pin sheath assembly 1 first is assembled into contact pin sheath assembly
Position is filled, then contact pin sheath assembly 1 is assembled to contact pin sheath assembly locking position.
1. when described cpa card 12 loads self-locking 113 inner side of cantilever, hook 121 is assemblied on self-locking cantilever 113 step
Side.
Step 2. TPA clamps 23 be assembled to TPA clamps prepackage position when, triangle boss 231 put in prepackage position groove 211
It is interior；When TPA clamps 23 are assembled to TPA clamp locking positions, triangle boss 231 is put in locking position groove 215.
For step when 3. described contact pin sheath assembly 1 is assembled to contact pin sheath assembly prepackage position, muscle structure 112 is with playing tongue
I221 is engaged, and boss 111 puts in the convex lower section of eaves 222；Continue downward firmly F2 behind prepackage position and push and plug needle shield 11, at this moment contact pin
Self-locking cantilever 113 on sheath 11 crosses the hanging platform 224 on protective case 22, reaches the locking position lock between contact pin sheath and socket jacket
Stop bit；After reaching the locking position locking position between contact pin sheath and socket jacket, solution lock key 3 is put in opening keyhole 225, is made
Play tongue I221 and retreat realization unblock.Muscle structure 112 is engaged with playing tongue I221, refers to playing the projecting block 2211 and muscle of tongue 221
The contact of structure 112 prevents contact pin sheath assembly from entering, and convex eaves 222 is that limit rib structure prevents contact pin sheath from deviating from；Protected in contact pin
The pre-installed position of assembly and socket jacket assembly 2 is covered, inserts key, pushes and plugs needle shield assembly, contact pin sheath assembly can enter shield
The whole lock position of inner room.
After reaching the locking position between contact pin sheath and socket jacket, firmly F3 pushes away cpa card 12 and allows it to shift contact pin sheath onto
The thorough locked sheath in locking position between assembly and cpa card, the hook 121 during locked sheath on cpa card 12 are crossed self-locking and hanged
The bottom of arm 113.Locking position between contact pin sheath and socket jacket is locking position between sheath, between contact pin sheath assembly and cpa card
Locking position be CPA lockings position.
The utility model is not limited only to six lines, line by taking six line socket sheath assemblies and six line contact pin sheath assemblies as an example
Number ＞ mono- linear system row are all contained in the scope of this patent.
Socket jacket assembly 2 and contact pin sheath assembly 1 are assembled by the cooperation of structure, from use position functions,
Assembling process is divided into the prepackage position and locking position of contact pin sheath assembly.When pre-installing position：Terminal 4 does not engage, and circuit disconnects, and socket
Sheath assembly 2 and contact pin sheath assembly 1 should be not easy directly to matching somebody with somebody or by instrument to the two is not readily separated, and this prevents for one-level
Fill by mistake；During locking position：Contact pin sheath assembly, which enters locking position, engages terminal, allows circuit communication, it is necessary to press self-locking cantilever dress
Locking position could be loaded with cpa card 12 by putting, and this is two level wrong-mounting prevention；, can be with addition in prepackage position in order to increase security insurance
Add and match somebody with somebody one solution lock key 3 thoroughly to prevent from causing Personal Risk because maloperation causes line conduction, this is that three-level is anti-error
Dress.The utility model puies forward the safety that can be maximized degree by the anti-error assembling structure of three-level and protect maintenance personal.
During the prepackage position of contact pin sheath assembly：Socket jacket assembly 2 passes through the bullet tongue I221 structures that are set on its protective case 22
Prepackage position is realized with the muscle structure 112 set in contact pin sheath 11, while lockhole is provided with contact pin sheath 11, socket jacket 21
On have be oriented to protection lockhole groove 226, the lockhole with lock by realizing thorough locking.During locking position：From prepackage position to locking
Position, it is necessary first to which, by stirring bullet tongue I221 structures on protective case 22, next needs to press the self-locking cantilever on contact pin sheath assembly 1
And firmly down push away, contact pin sheath 11 and socket jacket 21 is filled by the structure of hanging platform 224 and self-locking cantilever of socket jacket 21
Self-locking is put to realize locking.Then push down on cpa card 12 and ensure lock position and anticreep.
