Abstract
The utility model discloses a kind of velocity transducer with shading ring, velocity transducer inner walls is crimped with shading ring, shading ring is thin-walled annular structure, shading ring external diameter and housing inner diameter interference fit, the cable screen of velocity transducer welds with shading ring, solder joint is at shading ring inwall, and shading ring, cable screen all adopt Cu alloy material, electroplate.The utility model relies on shading ring to realize the connection of sensor cable screen and housing, connect safe and reliable, do not affect sensor performance, shading ring structure is simply, easy to operate.
Description
Technical field
The utility model relates to velocity transducer, particularly relates to the velocity transducer with shading ring.
Background technology
When supporting velocity transducer selected by traction electric machine, require that its cable screen is connected with housing, thus reach cable screen and motor object altogether.In prior art, cable screen is connected with sensor housing by the main metallic cable joint that adopts, and this metallic cable joint is in installation process, and screen is fragile, and the screen of damage may fall in housing, causes circuit board short circuit or insulation property to reduce; Metallic cable joint has larger contact impedance, and the Signal transmissions of velocity transducer may be made to be affected.Meanwhile, for coordinating with metal joint, housing inner diameter and cable external diameter all limited.
Utility model content
Technical problem to be solved in the utility model be overcome prior art above-mentioned deficiency and a kind of velocity transducer with shading ring is provided, rely on shading ring to realize the connection of sensor electrical cable screen and housing, and connect safe and reliable, do not affect sensor performance.
The technical scheme in the invention for solving the above technical problem is: with the velocity transducer of shading ring, velocity transducer inner walls is crimped with shading ring, shading ring is thin-walled annular structure, shading ring external diameter and housing inner diameter interference fit, the cable screen of velocity transducer welds with shading ring, and solder joint is at shading ring inwall.
Described shading ring, cable screen all adopt Cu alloy material, electroplate.
Described shading ring is spline structure.。
The utility model has the advantage of: 1, shading ring and cable screen adopt welding manner to be connected and fixed, shading ring crimps fixing with velocity transducer housing, shading ring external diameter and housing inner diameter are interference fit, contact area is large, contact is reliable, contact impedance is little, and the Signal transmissions of velocity transducer is not affected.Between shading ring and housing, fixing operation is convenient, covers ring structure simple.2, shading ring, cable screen all adopt Cu alloy material, electroplate, and performance is better.
Accompanying drawing explanation
Fig. 1 is partial sectional view of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is the structural representation of shading ring in Fig. 1, Fig. 2.
In figure: 1, housing, 2, cable screen, 3, shading ring, 4, solder joint.
Embodiment
Below in conjunction with accompanying drawing, embodiment, the utility model is further illustrated.
As shown in Figure 1 and Figure 2 with the velocity transducer of shading ring, comprise sensor housing 1, arrange inductive means, printed board etc. in housing 1, the afterbody of housing 1 is connected with bellows, and cable penetrates bellows and is connected with the parts in housing 1.
Go back fixed mask ring 3 in housing 1, the structure of shading ring 3, installation site are as shown in Figure 1 and Figure 2.Shading ring 3 is thin-walled annular structure, and the upper end of vertical annulus, with horizontal broadside, arranges horizontal broadside convenient crimping shading ring 3.Shading ring 3 is crimped on the inwall of housing 1, the external diameter of shading ring 3 and the internal diameter interference fit of sensor housing 1, and contact area is large, and contact is reliable, and contact impedance is little, and the Signal transmissions of velocity transducer is not affected.
Preferred shading ring 3 adopts Cu alloy material, and silver-plated process is carried out on surface, and by machine work or drawing, cable screen 2 is also silver-gilt copper wire, identical with surface treatment mode with the material of shading ring.Cable screen 2 welds with shading ring 3, and solder joint 4 is positioned at the inwall of shading ring 3.Certainly, according to material and the coating of selecting cable screen 2, the material of shading ring and coating can change accordingly, make both weld better.
In addition, shading ring 3 can be made into spline structure, save material, does not affect instructions for use.Because spline structure belongs to conventional structure, repeat no more.Except welding shading ring and cable screen, micro connector can also be adopted to connect.
Claims (3)
1. with the velocity transducer of shading ring, it is characterized in that: velocity transducer inner walls is crimped with shading ring, shading ring is thin-walled annular structure, shading ring external diameter and housing inner diameter interference fit, the cable screen of velocity transducer welds with shading ring, and solder joint is at shading ring inwall.
2. the velocity transducer with shading ring according to claim 1, is characterized in that: described shading ring, cable screen all adopt Cu alloy material, electroplate.
