Description
Technical field
The utility model belongs to a kind of technical field of automobile parts, and specifically one kind prevents double connector rain plug
The locking mechanical structure to fall off.
Background technique
The rain plug of automobile sealed connector, most of the time without independent lockable mechanism, especially with the connection of blind plugging
Device, in the case where relatively more severe, after through a long time high-frequency vibration, the risk that rain is plugged with disengaging connector and falls off, to make
Hermetically sealed connector lose seal protection effect, increase connector water inlet, ablation hidden danger, thus influence vehicle electrical safety and can
By property.
Summary of the invention
The utility model provides a kind of rain plug suitable for automobile sealed connector and locks, can quickly with connector and after
Protection assembly, can bear adverse circumstances and high-frequency vibration, be maintained at the rain plug of connector in connector by rain plug lock, guarantee
The reliability of hermetically sealed connector rain plug sealing, to guarantee that the electrical safety of vehicle and reliability prevent double connector rain plug
The locking mechanical structure to fall off solves the above-mentioned deficiency of existing rain plug.
Technical solutions of the utility model are described with reference to the drawings as follows:
A kind of locking mechanical structure for preventing double connector rain plug from falling off, the locking mechanical structure include positioning pin 1, lock
Only boss 2 and position limiting structure 3；The both ends of the position limiting structure 3 are locking boss 2；The positioning pin 1 is two preceding chamferings
Boss, and matched with two shrinkage pools of connector 11；The locking boss 2 is cantilever design；The position limiting structure 3
For semicircle boss；The locking boss 2 and position limiting structure 3 is matched with the left and right both ends of rain plug lock 7；The locking
Boss 2 and connector 8 are in the assembly of lock position 6 locking.
The utility model has the following beneficial effects:
1, the rain plug lock of the utility model is stand-alone configuration, can quickly be assembled with connector and rear protecting, is stablized, jail
Gu guaranteeing the reliability of rain plug sealing；
2, the rain plug lock of the utility model does not influence the installation of other attachmentes of connector, can connect with connector rear protecting.

Specific embodiment
Refering to fig. 1, Fig. 2, Fig. 3, a kind of locking mechanical structure for preventing double connector rain plug from falling off, the locking machinery knot
Structure includes positioning pin 1, locking boss 2 and position limiting structure 3；The both ends of the position limiting structure 3 are locking boss 2；Described determines
Position pin 1 is two preceding chamfering boss, matches realization precise positioning with two shrinkage pools of connector 11 at first；The rain plug lock
12 be stand-alone configuration part, and the rigging position of rain plug lock 12 is limited by locking boss 2 and position limiting structure 3 by left and right, Zhi Nengshang
Lower movement；The locking boss 2 is cantilever design；It is realized after salient point reaches 11 lock position of connector on single-cantilever whole
Locking effect；Position limiting structure 3 also reaches specified restraining position limitation rain plug 7 and is displaced at this time, and position limiting structure 3 is semicircle boss.
Refering to Fig. 3, the locking boss 2 and connector 8 are in the assembly of lock position 6 locking；Rain on the electric wire 4
Plug 7 and blind plugging 10 are limited structure 3 in restraining position 5 and are limited in the hole location of connector 11, prevent rain plug 7 from falling off.
Refering to Fig. 4, Fig. 5, locking 12 relevant connector assemblies to rain plug has connector 11, rain plug 7, blind plugging 10, harness 13
With bellows 14.Rain plug 7 is assemblied on the harness 13 protected by bellows 14 of outside, and rain plug locks 12 fronts and pushes down rain plug 7 and blind
It is clamped and locks with connector 11 after stifled 10.
The utility model is a kind of rain plug lock 12 of automobile sealed connector, can prevent rain plug 7 and blind plugging 10 from falling off, fill
With easy to operate, quick.
