Pipe 102, other cable-through hole pipes 102 are blocked.
In another example when the building blocks of function configured in outside rear-view mirror includes turn signal and camera, and turn signal and take the photograph
As the diameter of the cable of head connection is respectively φ 11 and φ 22.Then at this point, in multiple cable-through hole pipes 102, aperture size need to be used
The two cable-through hole pipes 102 to match with φ 11 and φ 22, other cable-through hole pipes 102 are blocked.
Therefore, the opening of the cable-through hole pipe 102 to come into operation is needed to want by selection in actual use, meet
It asks, meets the closure requirement of the cable-through hole pipe 102 without coming into operation again.The not exactly the same cable-through hole of multiple aperture sizes
The tail plug 103 being adapted to therewith is correspondingly arranged in pipe 102, tail plug 103 can both block corresponding cable-through hole pipe 102, can also be with
Operation is pulled out by artificial execution.Tail plug 103 be performed pull out operation when, it is disconnected that connection occurs with corresponding cable-through hole pipe 102
It is de-, to keep corresponding cable-through hole pipe 102 open, to come into operation.
One end (upper end anticipated as shown in figures 1 and 3) of tail plug 103 is arranged in corresponding cable-through hole pipe 102, and with
The inner wall of cable-through hole pipe 102 is detachably connected.The other end (lower end anticipated as shown in figures 1 and 3) of tail plug 103 is extended to the over
Extend outside string holes pipe 102 and along the direction away from base portion 101, can be rod-shaped in circular cone, area of section is along the side for deviating from base portion 101
It is gradually reduced to (direction from top to bottom anticipated as shown in figures 1 and 3), i.e. the circle small in the big other end in one end of tail plug 103
Cone rod shape.
Since the internal gutter of cable-through hole pipe 102 is also in the small circular cone shape of the big other end in one end, that is to say, that cable-through hole
The end of the separate base portion 101 of pipe 102 is actually small-bore.And the outer diameter of the end of the close base portion 101 of tail plug 103 compared with
Greatly.Therefore, there are the ends in aperture and tail plug 103 in the position of the end far from base portion 101 for the internal gutter of cable-through hole pipe 102
The identical position of outer diameter, the position are the position that cable-through hole pipe 102 is connected with tail plug 103.
Due to tail plug 103 be performed pull out operation when, tail plug 103 will be sent out in the inner wall of the position and cable-through hole pipe 102
Raw fracture.Therefore, which can be named as to fracture position (Break Point), as shown in Figure 3 and Figure 4.
The tilt angle of the internal gutter of cable-through hole pipe 102 is consistent with the tilt angle of tail plug 103, thus tail plug 103
It is not line contact when fracture position (Break Point) is connect with the inner wall of cable-through hole pipe 102, before the two, but face
Contact.I.e. fracture position (Break Point) has certain thickness.
Here consistent is it is to be understood that the tilt angle of the internal gutter of cable-through hole pipe 102 and the inclination of tail plug 103
The difference of angle is in preset range [0, δ].Alternatively, when both tilt angle difference when preset range [0, δ] is interior, i.e.,
It is believed that the tilt angle of the two is consistent.Wherein, the upper limit value δ of preset range can become according to different operative scenarios
Change, the embodiment of the present invention is not construed as limiting this.
The thickness of fracture position (Break Point) is the thickness of the inner wall contact connectio of tail plug 103 and cable-through hole pipe 102
Spend size, the size of the thickness not only influence tail plug 103 be performed pull out operation and with the inner wall of cable-through hole pipe 102 send out
The complexity of raw fracture, has an effect on the bonding strength of the inner wall of tail plug 103 and cable-through hole pipe 102.
Therefore, the design of the thickness is unsuitable too small, otherwise will lead to the inner wall of tail plug 103 and cable-through hole pipe 102
Bonding strength is on the weak side, in cable-through hole pipe 102 it is not necessary that when coming into operation and needing to block it by tail plug 103, there are tail plugs
103 is insufficient with the bonding strength of the inner wall of cable-through hole pipe 102 and the phenomenon that tail plug 103 falls off occur.
But the design of the thickness also should not be too large, and otherwise will lead to the inner wall of tail plug 103 Yu cable-through hole pipe 102
Bonding strength it is excessive, subsequent to pull out operation to the execution of tail plug 103, tail plug 103 is not easy and the generation of the inner wall of cable-through hole pipe 102
Fracture；Alternatively, there is the case where tail plug 103 pulls cable-through hole pipe 102, cable-through hole pipe 102 is torn.
In view of this, after factor of both tradeoff bonding strength and the easiness of fracture, tail plug 103 and cable-through hole pipe
The thickness that 102 inner wall connects, the i.e. thickness of fracture position (Break Point) between 0.4mm-1.2mm compared with
Be it is suitable, may further be 0.5mm-1.1mm, further can be 0.6mm-1.0mm.
In the present embodiment, what tail plug 103 was performed pulls out operation, can specifically include, and radially (transverse direction) shakes tail
Plug 103.To which tail plug 103 can radially wobble, and then the inner wall of tail plug 103 and cable-through hole pipe 102 is broken in junction
(Break Point) is cracked for position.With the increase for the increase and amplitude for shaking number, what the two junction occurred splits
Line extension, can then execute it and pull out operation, tail plug 103 is detached from from corresponding cable-through hole pipe 102.
Since one end (upper end anticipated as shown in figures 1 and 3) of the close base portion 101 of tail plug 103 is arranged in cable-through hole
The other end (lower end anticipated as shown in figures 1 and 3) in pipe 102, therefore in order to avoid cable-through hole pipe 102 far from base portion 101
And the swing of tail plug 103 is interfered or stopped to side wall, the inner wall of the other end of cable-through hole pipe 102, which is thinned, forms anti-interference portion
The outer wall of 102c, anti-interference portion 102c and tail plug 103 is separately.To which anti-interference portion 102c and the outer wall of tail plug 103 are formed with
Avoiding space 102d, avoiding space 102d are empty for providing swing for tail plug 103 when tail plug 103 is performed and pulls out operation
Between.
In the present embodiment, the height of anti-interference portion 102c can between 0.5mm-1.0mm value, may further be
0.6mm-0.9mm further can be 0.7mm-08mm.And width (the i.e. wall of anti-interference portion 102c of avoiding space 102d
Difference of the thickness compared to the wall thickness of 102 other parts of cable-through hole pipe) can between 0.5mm-1.0mm value, may further
It further can be 0.7mm-08mm for 0.6mm-0.9mm.
By the integrated molding scheme of injection molding manner, tail plug 103 and line is crossed by above-mentioned tail plug 103 and cable-through hole pipe 102
The structure design of thickness design and anti-interference portion 102c that the inner wall of hole pipe 102 connects, when so that tail pipe being pulled out
Fracture position (Break Point) and area of fracture (aperture i.e. at the corresponding fracture position of cable-through hole pipe 102) keep
Certain value.
That is, in the identical situation of radial dimension of cable-through hole pipe 102, after tail plug 103 and the disengaging of cable-through hole pipe 102,
