Description
Technical field
The utility model is related to a kind of electric connector, and in particular to a kind of full water-proof type buckle electric connector.
Background technology
With the complication of connector application environment, the sealing to electrical connector plug and socket proposes higher want
Ask, and this requirement can become a kind of standard configuration.It is well known that the sealing property of connector plugging state does not ensure, directly lead
Cause the resistance to environment capacity of connector drastically to decline, occur being connected with unreliable, serious meeting and cause connector to fail.
The sealing present situation of current tradition bayonet connector generally.Coupling nut helicla flute inner hole surface is machined with three
Helicla flute, three helicla flutes are symmetric, matching corresponding with the bayonet lock on socket.When bayonet coupling connector is plugged together or separated,
Coupling nut is screwed by radial direction, makes three bayonet locks on socket in three inner spiral grooves along spiral motion track, so as to realize axle
To plug together or separating action.
When bayonet coupling connector plug together action completion, to reach the lock function of plug, socket, in coupling nut
Three inner spiral groove ends be machined with three helicla flutes and fall mouth, its effect is three bayonet locks on the socket edge in three inner spiral grooves
Spiral motion track to helicla flute end when, enter three helicla flutes fall it is intraoral.Due to the presence of wavy spring, plug,
Socket plug together action all the time can compressed waveform spring so that three bayonet locks 21 exist and wavy spring all the time in three inner spiral grooves
The reaction force mutually resisted of elastic force, this reaction force makes three bayonet locks produce locking when three helicla flutes fall intraoral and make entering
With realizing lock function.
Meanwhile, the processing method that three traditional helicla flutes fall mouth is to process three through holes in the end of three inner spiral grooves, i.e.,
Pin hole on coupling nut.This just forms a sealed leakage point.
An inner seal ring is installed for socket, in socket, it is plugged together with plug casing after plug, socket are plugged together
End face produces compression, so as to reach sealing effectiveness.
It in summary it can be seen, traditional bayonet connector is after plug, socket are plugged together, and its seal form is by plug casing
Plug together end produce compression come what is realized, it is single seal point, and bayonet coupling connector is by wavy spring
Compression stress produces coupling mechanism force, and it is a kind of elastic force, rather than rigid locking（Such as screw-threaded coupling）Power, it is inherent to have the disadvantage
Strength is unbalanced in a circumferential direction（Caused by reason is wavy spring structure in itself and bending moment suffered by connector）, this
The unbalance of seal compression power has been resulted in, sealed failure is easily caused.So such sealing means reliability is not high, with very
Big risk.Furthermore, as shown in figure 3, plug, socket are plugged together after locking, while in the presence of gap at 1,2,3 three, herein at three, and
Do not do encapsulation process.In the practical application of conventional bayonet connector, leakage is inevitably produced at above-mentioned three.
Sealing point failure, housing aggravation burn into or even the separation that can not be plugged together are thereby resulted in, the ultimate failure of connector is caused！Ensure
The hermetically sealed performance of bayonet coupling connector is the task of top priority.
