Embodiment
As shown in Figure 1; the present invention proposes a kind of self-locking protective sleeve 100; made by plastic material, it comprises that an insulating body 1, is located at the sheet 2, that snaps in of these insulating body 1 one ends and is located at the shackle member 3, of the other end of this insulating body 1 and is located at this and snaps near the sheet 2 catch 4.
This snaps in sheet 2 and comprises that a sheet body 22, that snaps in that extends vertically upward from this insulating body 1 snaps in the leg-of-mutton tapered end 24 that sheet body 22 ends extend to form from this.
This tapered end 24 comprises that one snaps in that sheet body 22 extends and the leg-of-mutton guide head that forms 242, two snap in sheet body 22 front ends from this respectively and extend and the leg-of-mutton fixture block 244 that forms to relative both sides along this.
This shackle member 3 comprises that two extend upward the clamping sheet 32 that forms from this insulating body 1.This two clampings sheet 32 is parallel, leaves between this two clampings sheet 32 for this and snaps in the space that sheet 2 inserts.The inwall of this two clampings sheet 32 terminal downwards in direction each extend and be provided with one first card base 322 that should fixture block 244.
On the inwall of this two clampings sheet 32 near this insulating body 1 position downwards in direction each extend and be provided with a pair of second card base 324 that should fixture block 244.
This catch 4 extends vertically upward from this insulating body 1 and forms.
When this snapped in sheet 2 and inserts in these shackle member 3, these two first card bases 322 and these two second card bases 324 can be stuck on these two fixture blocks 244, and can effectively stop this to snap in sheet 2 to withdraw from from shackle member 3.Snapping between sheet 2 and the clamping sheet 3 is that laminated structure links to each other.
As shown in Figure 2; if the protection bus was arranged 200 o'clock; can be used with two above-mentioned self-locking protective sleeves; the sheet 2 that snaps in of first protective sleeve 100 is inserted in the shackle member 3 ' of second protective sleeve 100 '; having this guide head 242 can make this snap in sheet 2 is easy to be inserted in this shackle member 3 '; two first card bases 322 ' of this shackle member 3 ' are stuck on 100 two fixture blocks 244 of this first protective sleeve; this two card base 322 ' withstands on these two fixture blocks 244; can stop this to snap in sheet 2 and from shackle member 3 ', withdraw from, snap in sheet 2 and also can't withdraw from even be pulled outwardly this.This first protective sleeve 100 and second protective sleeve 100 ' are encased this bus row 200; with the snapping in the shackle member 3 that sheet 2 ' inserts first protective sleeve 100 of second protective sleeve 100 ', these two first card bases 322 are stuck on two fixture blocks 244 ' of this second protective sleeve 100 ' then.After installing; the insulating body 1 of this first protective sleeve 100 and the insulating body 1 ' of second protective sleeve 100 ' wrap in this bus row 200 both sides; the catch 4 of this first protective sleeve 100 and the catch 4 ' of second protective sleeve 100 ' keep off the both sides in addition this bus row 200 respectively; therefore, this bus row 200 is just protected tightly in these two protective sleeves.
As shown in Figure 3, if another bus row 200 ' thickness is less, can snap in sheet 2 to this and snap in sheet 2 ' and inwardly block deeperly, allow two second card bases 324 ' be stuck on these two fixture blocks 244, allow two second card bases 324 be stuck in this two fixture blocks 244 ' and go up and get final product.
When practical application; two first card bases of first protective sleeve can also be blocked two fixture blocks of second protective sleeve; two second card bases of second protective sleeve are blocked two fixture blocks of first protective sleeve, can encase the middle-sized bus row of size between Fig. 2 and bus shown in Figure 3 row like this.
As shown in Figure 4; if the protection bare wire is not when (figure shows); only need to get final product with a self-locking protective sleeve of the present invention; the sheet 2 that snaps in of this protective sleeve 100 is inserted in this shackle member 3; two first card bases 322 of this shackle member 3 are stuck on these two fixture blocks 244; this two card base 322 withstands on these two fixture blocks 244, can stop this to snap in sheet 2 and withdraw from from shackle member 3, snaps in sheet 2 and can not withdraw from even be pulled outwardly this.Therefore, can closely protect this bare wire.
Similarly, also can be stuck in and protect the less bare wire of diameter on two fixture blocks 244 by two second card bases 324.
The preparation method of self-locking protective sleeve 100 of the present invention is as follows: raw material is dropped in the single screw extrusion machine; extrusion temperature is controlled between 90--150 ℃; raw material is fed forward by screw rod; through extrusion die, after wind or water cooling, obtain self-locking protective sleeve; after perhaps coming out from extrusion die; by a shaping mechanism cooling and shaping, after wind or water cooling, obtain self-locking protective sleeve.
Among the present invention; not only be provided with two first card bases 322 in this shackle member 3; and be provided with two second card bases 324; this fixture block 244 that snaps in sheet 2 can cooperate with this first card base 322; also can cooperate with this second card base 324; can with snap in sheet 2 securely kayser in shackle member 3, still be second card base 324 but can select with first card base 322 according to protected bare wire diameter or bus row size.In addition, the inwall of two clamping sheets downwards in direction extend the card base of corresponding fixture block, be stuck on two fixture blocks, this structural stability height can stop to snap in sheet and withdraw from from shackle member effectively.
It more than is the first embodiment of the present invention; be provided with two groups of card bases and snap in sheet 2 and cooperate,, can be provided with three groups or more groups of card bases according to the present invention; so just make the excursion of bare wire diameter that protective sleeve can protect or bus row size bigger, just the adaptability of protective sleeve is stronger.
More than be the first embodiment of the present invention, above-mentioned guide head 242, fixture block 244 are triangles.According to essence of the present invention, this guide head 242 can be oblate, inserts in this shackle member 3 smoothly as long as the shape of this guide head 242 can help it.This fixture block 244 also can be oblate, as long as can allow first card base 322, second card base 324 and fixture block 244 cooperate preferably.
