Description
Technical field
The present invention relates to sensor and bellows connector, more particularly to the seal nipple with function of shielding.
Background technology
In locomotive and urban rail field, for the matched velocity sensor of traction electric machine, due to installation operation limited space,
It is required that it is miniaturized.As existing running environment requires more and more higher, it is necessary to be realized in the miniaturization space of velocity sensor
Cable shielding line is connected altogether with housing, to realize good EMC performances；It is to realize cable protection, it is necessary to install additional simultaneously
Corrugated flexible hose, and flexible pipe needs good fixed locking and sealing with transferring for Sensor tail leading-out terminal.
Existing hose coupling is universal standard part, there are three shortcomings on sensor：1st, it is to coordinate with hose coupling,
Sensor housing dimension of inner and outer diameters is limited, and is difficult to realize the miniaturization of sensor；2nd, the corrugated flexible hose of protective cable line
Locking can not directly be fixed and sealed, cause the flexible pipe at sensor leading-out terminal can not fixing band carry out the hidden danger of cable stress,
Sealing property can not meet demand simultaneously；3rd, contact resistance when cable shielding line is connected with housing is bigger than normal, and then influences
The common ground effect of shielding line and housing, causes EMC impaired performances.
The content of the invention
The technical problems to be solved by the invention are to overcome the above-mentioned not enough of prior art and provide a kind of band function of shielding
Sylphon seal joint, improve shield effectiveness, anti-interference and sealing property, coordinate firm.
The present invention the used technical scheme that solves the above problems is：Sylphon seal joint with function of shielding, sealing
Joint includes shading ring, sealing ring, hold-down ring and locking member, and shading ring is made up of copper alloy, the front inner wall welding of shading ring
Socket bellows front end, ripple on the outside of shielding line, outer wall and sensor housing internal wall transitions or interference fit, the rear end of shading ring
Pipe front end outer side is socketed socket hold-down ring on the outside of sealing ring, sealing ring, and hold-down ring is contacted with sensor housing inwall, locking member peace
Mounted in sensor housing tail end.
The front end of the shading ring, rear end transition position are carried to be provided with before annular groove, facade and sealing ring on facade, facade
End contact.
Further improved scheme：Sealing ring is made up of rubber, and inwall carries ring-shaped step, and front end outer side is with annular
It is made of stainless steel on the outside of muscle, annular muscle and sensor housing interference fits, sealing ring rear end with wedge shape, hold-down ring, front end
With the wedge shape matched with sealing ring rear end wedge shape.
Compared with prior art, the advantage of the invention is that：1st, the shielding line of cable and copper alloy shading ring are welded, screen
Ring and sensor housing transition or interference fit are covered, can control the contact resistance between the shielding line of cable and sensor housing
In the range of 1 Ω, shielding line and housing effect altogether are improved, good anti-EMC performances are realized.2nd, bellows is arranged on shading ring
Fastened between sealing ring, and by hold-down ring, locking member, by setting the knots such as annular muscle, annular groove, wedge shape, ring-shaped step
Structure, makes sealing ring keep good contact with sensor housing, shading ring, hold-down ring, bellows, and with certain elasticity, it is close
Seal effect stronger.3rd, sensing can be met while realizing the switching of sensor leading-out terminal according to each part of shell dimension designed joint
The miniaturized design of device.

Embodiment
Below in conjunction with the accompanying drawings, the present invention is further described for embodiment.
As shown in figure 1, seal nipple is used to connect sensor housing 1 and bellows 7, seal nipple includes shading ring 3, close
Seal ring 4, hold-down ring 5, clamp nut 6.
The structure of shading ring 3 is as shown in Fig. 2 the cylinder that shading ring 3 is communicated by rear and front end is constituted, and front end is shielding end
32, inwall is welded with shielding line 2, and front end outer wall and sensor housing transition or interference fit, the external diameter of front end are outer compared with rear end
Footpath is big, and rear end is support end 31, and support end 31 is used to support bellows 7, prevents bellows 7 from being deformed by the extruding of sealing ring 4.
The facade for shielding the transition position between end 32 and support end 31 carries annular groove 33, after being assembled with sealing ring 4, facade and sealing ring
4 front end face keeps good contact, it is ensured that suitable decrement is to realize good sealing property, and shading ring 3 uses copper
Alloy is made.
Sealing ring 4 is made up of rubber, and structure is as shown in figure 3, the inwall of sealing ring 4 is used for and ripple with ring-shaped step 41
Line pipe 7 is assembled, fixed and sealing；The front end outer side of sealing ring 4 carries annular muscle 42, and the inwall of annular muscle 42 and sensor housing connects
Touch, annular muscle adds the Elastic penetration between sensor housing 1, realizes good sealing effectiveness；Design the rear end of sealing ring 4
Wedgewise structure, is easily installed hold-down ring 5.
Hold-down ring 5 is made of stainless steel, and structure is as shown in figure 4, before the Front-end Design wedgewise structure of hold-down ring 5, hold-down ring 5
The wedge shape at end is engaged with the wedge shape of the rear end of sealing ring 4, is easily installed and compresses sealing ring 4.
Clamp nut 6 is made of stainless steel, and structure is as shown in figure 5, the threads of clamp nut 6 and sensor housing 1
Connection.
Assembling process is as shown in fig. 6, shielding line 2 loads in bellows 7, and by clamp nut 6, hold-down ring 5, sealing ring 4
One end of bellows 7 is sequentially sleeved in, shielding line 2 penetrates shading ring 3, after the completion of shielding line 2 is welded with the front inner wall of shading ring 3,
Shading ring 3 is pressed into sensor housing 1 using corresponding frock, shading ring 3 is interference fitted with the transition of sensor housing 1；
Sealing ring 4 is mounted in the outside of the one end of bellows 7, while load the rear end support end 31 of shading ring 3, make the inner side of bellows 7 with
The afterbody of shading ring 3 is installed in place；By hold-down ring 5 in advance mounted in the outside of sealing ring 4, clamp nut 6 is locked using spanner.
Obviously, the quantity and size of annular groove, the quantity and size of annular muscle and ring-shaped step, clamp nut length and chi
Very little, overall structure size can be adjusted according to the actual requirements, and clamp nut can also be replaced using other locking members.
