Abstract
The utility model relates to a connection zone of wire and terminal with seal structure, connection zone includes wire, terminal and sealing layer, the terminal is connected with the wire and is formed certain interstitial region, the sealing layer includes polyvinyl chloride film and coating in the polyvinyl chloride film central butyl rubber cement gum layer in one side, wherein, butyl rubber cement gum layer fills in the interstitial region of terminal and wire and the outside of terminal, polyvinyl chloride film covers in butyl rubber cement gum layer's the outside. Compared with the prior art, the utility model discloses to the sealed requirement that has heterotypic crimping cross -section, convenient to use, the any equipment of independence just can reach good sealed effect, and low cost, has fine practical application and worth.
Description
Technical field
This utility model relates to the crimping field of wire and terminal, is specifically related to the sealing knot of a kind of terminal welding region
Structure.
Background technology
In wire harness industry, the sealing of the crimp region of wire and terminal is typically used the protection side of band glue heat-shrink tube at present
Case, the protection of this band glue heat-shrink tube is highly effective for having the crimping district in rounding cross section, but connects for abnormal shape
The sealing in region to reach to have fully sealed bigger difficulty, and it is higher to realize cost the most in other words.This be by
The characteristic of heat-shrink tube itself determines, is along internal diameter direction uniform shrinkage in a free state due to heat-shrink tube, different when running into
Cannot effectively seal due to horizontal and vertical uneven the frequently resulting in of contraction during type cross section.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and provide one to be applicable to end
Sub-join domain, can the sealing structure of the effective terminal connection area of waterproof sealing.
The purpose of this utility model can be achieved through the following technical solutions: a kind of with the wire and the end that seal structure
The join domain of son, described join domain includes that wire, terminal and sealant, described terminal are connected with wire and are formed certain
Gap area, described sealant include polyvinyl chloride film and be coated on polyvinyl chloride film side central authorities butyl rubber glue
Mud layer, wherein, in described butyl rubber clay layer is filled in the gap area of terminal and wire and the outside of terminal, described poly-
Vinyl chloride film is covered in the outside of butyl rubber clay layer.
Described polyvinyl chloride film is (1.5～2) with the area ratio of butyl rubber clay layer: 1.
The thickness of described polyvinyl chloride film is (0.1～0.2) mm.
The thickness of described butyl rubber clay layer is (0.5～2) mm
Described wire includes welding or crimps with the connected mode of terminal.
When for having the crimp region sealing of unconventional profile, enter gap area, glue by external force extruding clay
There is plastic deformation and be attached on wire and terminal in mud after extruding, for how to fill can be used for outer masterpiece completely
Adjust, to ensure that gap area can effectively be filled, reach the effect of waterproof sealing.Outer layer polyvinyl chloride film is good simultaneously
It is fitted in well outline region and plays dust-proof, insulation and effect attractive in appearance.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects:
(1) for having the seal request in special-shaped crimping cross section, easy to use, just can reach good not against any equipment
Sealing effectiveness；
(2) for the sealing in difference crimping cross section, all can be fully achieved by adjusting the thickness of external force and glue-line；
(3) compared with prior art (such as heat-shrink tube), cost is cheaper.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of sealant material therefor.
Wherein, 1 is terminal, and 2 is wire, and 3 is sealant, and 31 is polyvinyl chloride film, and 32 is butyl rubber clay layer.
Detailed description of the invention
Elaborating embodiment of the present utility model below, the present embodiment is being front with technical solutions of the utility model
Put and implement, give detailed embodiment and concrete operating process, but protection domain of the present utility model does not limits
In following embodiment.
Embodiment 1
A kind of wire with sealing structure and the join domain of terminal, its structure is as it is shown in figure 1, this sealing structure includes
Wire 2, it is connected to the terminal 1 outside wire 2 and sealant 3.Wire 2 is connected with abnormity terminal 1 by crimping.
Wherein, the structure of sealant is as in figure 2 it is shown, sealant by polyvinyl chloride film 31 and is coated on polyvinyl chloride film
The butyl rubber clay layer 32 of 31 side central authorities forms, and wherein, the thickness of polyvinyl chloride film 31 is 0.2mm, butyl rubber glue
The thickness of mud layer 32 is 1mm.
Have only to use butyl rubber clay layer 32 one side in external force sealant 3 to be fitted in the crimping needing to seal during use
Region, and wrapped up tight, enter wire 2 and the gap area of terminal 1, butyl rubber by external force extruding butyl rubber clay
There is plastic deformation and be attached on wire 2 and terminal 1 in glue clay after extruding, it is ensured that gap area can effectively be filled out
Filling, can reach good waterproof sealing effect, the polyvinyl chloride film 31 good fit contour area outside of outer layer rises simultaneously
To dust-proof, insulation and effect attractive in appearance.
Embodiment 2
Use the join domain similar with embodiment, in place of difference, be that sealant used is different, the present embodiment
Sealant is by polyvinyl chloride film and is coated on the butyl rubber clay layer of polyvinyl chloride film side central authorities and forms, wherein, poly-
Vinyl chloride film is 3:2 with the area ratio of butyl rubber clay layer, and the thickness of polyvinyl chloride film is 0.1mm, butyl rubber
The thickness of clay layer is 0.5mm.After testing, the join domain of the present embodiment can reach good waterproof sealing effect.
Embodiment 3
Use the join domain similar with embodiment, in place of difference, be that sealant used is different, the present embodiment
Sealant is by polyvinyl chloride film and is coated on the butyl rubber clay layer of polyvinyl chloride film side central authorities and forms, wherein, poly-
Vinyl chloride film is 2:1 with the area ratio of butyl rubber clay layer, and the thickness of polyvinyl chloride film is 0.15mm, butyl rubber
The thickness of clay layer is 2mm.After testing, the join domain of the present embodiment can reach good waterproof sealing effect.
