Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
Obtain other attached drawings according to these attached drawings.
Fig. 1 is the structural schematic diagram after the overall package of the present invention；
Fig. 2 is the structural schematic diagram after sealing of the present invention is ejected.
Coding in figure is respectively：1 is the second magnet, and 2 be arc raised line, and 3 be sealing, and 4 be the first magnet, and 5 be electricity
Core, 6 be fixing bracket, and 7 be support portion, and 8 be horizontal plane, and 9 be rounded transitional face, and 11 be inclined guide surface, and 12 be fixation
Axle sleeve, 13 be lattice, and 14 be metal clips, and 15 be cable serving, and 16 be arc catching groove, and 17 be assembly cavity.
Specific implementation mode
As shown in Figure 1, intrinsic safety full cable, including cable serving 15, the midfeather of cable serving 15 are arranged one piece
The two bottom sides of above lattice 13, lattice 13 are respectively provided with a support portion 7, the outer quilt of support portion 7, lattice 13 and cable
Layer 15 is PVC material；
The both sides of cable serving 15 respectively open up more than one assembly cavity 17 be connected with external connection, in assembly cavity 17
Activity is packed into a sealing 3, and the sealing of sealing 3 buckles into assembly cavity 17, and 3 inner end of each sealing is respectively provided with a support portion
7, the upper end of each support portion 7 is both provided with an ejecting mechanism；
The inner end of sealing 3 is respectively provided with two fixing brackets 6, is filled in the round assembly cavity of 6 outboard end of fixing bracket
Enter a cable core 5, one first magnet 4 of embedded setting, the first magnet 4 faces in the sealing 3 between two cable cores 5
Ejecting mechanism setting in cable serving.
Wherein, ejecting mechanism includes two metal clips 14, and a fixed hub 12 is welded in the bottom of metal clips 14, fixed
The bottom of bottom open end insertion one second magnet 1 of setting of axle sleeve 12, the second magnet 1 is the poles S, the 4 opposite ejection of the first magnet
Mechanism side is the poles S, and 14 top insertion of metal clips is set in cable serving 15.It is set since the S of two magnet is extremely opposite
It sets, therefore can be there are one ejecting force after adjacent to each other.
There are one inclined guide surface 11,1 one side of the second magnet of ejecting mechanism is tight for setting between lattice and support portion
It is arranged close to inclined guide surface 11, the upper surface of support portion 7 is a horizontal plane 8, is set between horizontal plane 8 and inclined guide surface 11
Rounded transitional face 9 there are one setting.
The upper and lower side of sealing opens up an arc catching groove 16, and the assembly cavity top and bottom of face arc catching groove 16 are respectively provided with
There are an arc raised line 2, the sealing of arc raised line 2 to buckle into arc catching groove 16, one end insertion of fixing bracket 6 is set to sealing
In the bracket holes of 3 inner end of portion.Sealing completes sealing positioning assembly by arc catching groove and arc raised line, simple and convenient, should
The assembly method of structure may insure to seal, but can be ejected under external force again, and design is very rational.
When cable integral head is pressed down, entire metal clips declines, and the second magnet declines along inclined guide surface, and
Finally enter horizontal plane upper end along arc-shaped transitional surface so that the second magnet originally contacted with inclined guide surface it is face-down,
90 degree of bendings of metal clips；
In ejection process, second the first magnet of magnet distance can be increasingly closer, due to being arranged for the homopolarity of two magnet, because
This will produce prodigious magnetic thrust after, finally overcome the assembly force of sealing and cable serving, sealing is by magnetic force
Ejection, but if pressure is very big, regardless of magnetic thrust is big, the end face of the second magnet is eventually terminated on the inside of sealing
It touches, completes ejection action, as shown in Fig. 2, in order to which cable core can be smoothly ejected, cable core should when laying
There are enough length to be ejected, i.e., in assembly, cable core preferably there are several sections of gauffer section, facilitates cable after ejection
Yielding.
The beneficial effects of the invention are as follows：The configuration of the present invention is simple has extraordinary safeguard protection performance, using extruding
The sealing being movably installed in assembly cavity is ejected, and then cable core is ejected by power, avoids the shearing under larger pressure,
Preferably protection cable.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection domain should be determined by the scope of protection defined in the claims.
