Abstract
It the utility model is related to a kind of sealing structure being used between button switch rubbery outer cover and cable, the structure is located at the junction with cable on pick up button switch rubbery outer cover, in the faucal of pick up button switch rubbery outer cover and the connecting portion coaxial package thermoplastic sleeve pipe of cable, the thermoplastic sleeve pipe, which is divided into, tightens section and filled section, one layer of polyurethane resin is brushed between the thermoplastic sleeve pipe where tightening section and faucal oral area and cable outer rim, section is tightened closely to coat the faucal of pick up button switch rubbery outer cover by way of heat seal, insulating resin is filled with filled section.The sealing device provided by the utility model being used between button switch rubbery outer cover and cable improves the seal degree between button switch rubbery outer cover and cable from inside to outside.
Description
Technical field
The utility model belongs to sensor field, is related to connector manufacture, especially a kind of to be used for outside button switch rubber
Sealing structure between shell and cable.
Background technology
The pick up button switch that applicant is produced, is often installed on high ferro train, use environment is non-
Normal harsh, the sealing problem between rubbery outer cover and cable, it appears it is particularly important, only by close between caoutchouc elasticity and cable
Envelope, it is impossible to meet severe use environment and high-grade seal request.And existing sealing structure can not still be fully met
State requirement.
Utility model content
The purpose of this utility model is in place of overcome the deficiencies in the prior art, there is provided one kind is easy to welding, stable connection
Be used for sealing device between button switch rubbery outer cover and cable.
The utility model solves its technical problem and takes following technical scheme to realize：
A kind of sealing structure being used between button switch rubbery outer cover and cable, the structure are located at pick up button switch
On rubbery outer cover with the junction of cable, it is characterised in that：In the faucal and cable of pick up button switch rubbery outer cover
Connecting portion coaxial package thermoplastic sleeve pipe, the thermoplastic sleeve pipe, which is divided into, tightens section and filled section, the thermoplastic sleeve pipe where section is tightened
One layer of polyurethane resin is brushed between faucal oral area and cable outer rim, section is tightened and is opened pick up button by way of heat seal
The faucal for closing rubbery outer cover is closely coated, and insulating resin is filled with filled section.
Moreover, the section that tightens is located at outside faucal oral area outer rim and the faucal of pick up button switch rubbery outer cover
Cable outer rim position on.
Moreover, the insulating resin is polyurethane resin.
The advantages of the utility model and good effect are：
The sealing device provided by the utility model being used between button switch rubbery outer cover and cable passes through thermoplastic sleeve pipe
The connecting portion of button switch rubbery outer cover and cable is closed, then by the thermoplastic sleeve pipe to faucal position by poly- ammonia
Ester resin-coating thereby increases seal in faucal, thus real then again to filling insulating resin in remaining thermoplastic sleeve pipe
Sealing and insulation outside existing cable, improve the seal degree between button switch rubbery outer cover and cable from inside to outside.
Brief description of the drawings
Fig. 1 is the attachment structure schematic diagram (axis section view) of button switch rubbery outer cover and cable；
Fig. 2 is attachment structure schematic diagram of the present utility model (axis section view).
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by specific embodiment, and following examples are simply retouched
The property stated, be not limited, it is impossible to limit the scope of protection of the utility model with this.
A kind of sealing structure being used between button switch rubbery outer cover and cable, the position of the structure, is shown in Fig. 1, is located at
Junction on pick up button switch rubbery outer cover 1 with cable 2.The concrete scheme of the structure is：
Fig. 2 is seen, in the faucal of pick up button switch rubbery outer cover and the connecting portion coaxial package thermoplastic set of cable
Pipe 3, the thermoplastic sleeve pipe, which is divided into, tightens section L1 and filled section L2, wherein, tighten section and be located at pick up button switch rubbery outer cover
Faucal oral area outer rim and faucal outside cable outer rim position on, for pick up button to be switched into rubbery outer cover
Faucal is closely coated, and a strata urethane tree is brushed between the thermoplastic sleeve pipe where tightening section and faucal oral area and cable outer rim
Fat, tighten section and closely coated the faucal of pick up button switch rubbery outer cover by way of heat seal, it is in filled section, i.e., hot
Insulating resin 4 is filled between plastic casing pipe remainder and cable.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, those skilled in the art can be with
Understand：Do not departing from the utility model and spirit and scope of the appended claims, it is various replace, change and modifications all be can
Can, therefore, the scope of the utility model is not limited to embodiment and accompanying drawing disclosure of that.
