Abstract
The invention relates to the technical field of sensors, in particular to an ultrasonic sensor with coating improved. The ultrasonic sensor comprises an ultrasonic probe, wherein a metal casing covers the ultrasonic probe, the ultrasonic probe is connected with a plug through two leads, fillets are arranged on the edge of the top surface of the metal casing, and the radius of each fillet ranges from 0.5 mm to 0.8 mm. According to the ultrasonic sensor with coating improved, paint is prevented from accumulating at the fillets of the metal casing during spraying.
Description
Technical field
The present invention relates to sensor device technical field, particularly relate to a kind of ultrasonic sensor improving application.
Background technology
Ultrasonic sensor is the sensor utilizing hyperacoustic characteristic to develop; At present when ultrasonic sensor probe metal shell surface sprays, generally by paint sprayer, paint is sprayed on the surface of metal shell, but due to metal shell surface fillet too small, when spraying, fillet place easily produces accumulation; Cause ultrasonic sensor surface spraying paint outward appearance and ultrasonic sensor surface spraying hundred Gree adhesion all defective.
Summary of the invention
The object of this invention is to provide and avoid metal shell fillet place to produce a kind of ultrasonic sensor improving application piled up when spray paint.
Technical scheme of the present invention is as follows:
Improve a ultrasonic sensor for application, comprise ultrasonic probe, the metal shell that the cover outside ultrasonic probe is established; Described ultrasonic probe is by the attachment plug of two lead-in wires; Described metal shell top edge is provided with fillet, and this radius of corner is 0.5mm-0.8mm.
Described two lead-in wires are wound around mutually.The mutual stranded winding after-current direction that goes between is on the contrary instantaneous, can reach counteracting, thus slacken the electromagnetic radiation in lead-in wire.
Described metal shell adopts aluminium shell.Adopt aluminium shell price low, reduce production cost.
Described radius of corner is 0.7mm.Because radius of corner adopts 0.7mm, paint can be effectively avoided to pile up in fillet place angulation.
The invention has the beneficial effects as follows: because metal shell top edge radius of corner is between 0.5mm-0.8mm; When carrying out spray treatment to metal shell surface, paint can be avoided to pile up in fillet place angulation, painting hundred lattice adhesion requirements to meet ultrasonic sensor appearance test request and to meet ultrasonic sensor surface spraying.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is structural representation of the present invention;
In accompanying drawing, 1 is ultrasonic probe, and 2 is metal shell, and 3 is lead-in wire, and 4 is plug, and 5 is fillet.
Embodiment
Shown in Figure 1, a kind of ultrasonic sensor improving application, comprises ultrasonic probe 1, the metal shell 2 that the cover outside ultrasonic probe is established; Described ultrasonic probe is by 3 attachment plugs 4 of two lead-in wires; Described metal shell top edge is provided with fillet 5, and this radius of corner is 0.5mm-0.8mm; Because metal shell top edge radius of corner is between 0.5mm-0.8mm; When carrying out spray treatment to metal shell surface, paint can be avoided to pile up in fillet place angulation, painting hundred lattice adhesion requirements to meet ultrasonic sensor appearance test request and to meet ultrasonic sensor surface spraying; When radius of corner is less than 0.5mm, fillet place easily produces accumulation; When radius of corner is greater than 0.8mm, when reversing automobile instrument radar backing system detects ultrasonic sensor, measurement result out of true can be caused.
Ultrasonic sensor surface spraying paint External Observation method for testing:
1, light source: 40W electricity-saving lamp, preheating 30 minutes;
2, examiner's eyesight: more than 1.0 (containing correcting defects of vision), without colour blindness;
3, visual range: 30cm;
4, visual angle: normal direction angle 45 °;
5, grain thing size definition: grain thing is surrounded with minimum circle, then round size and the size of grain thing;
6, compare with positive, positive needs annual replacing once.
Determinating reference: outward appearance needleless, scuffing, current mark, leak source, stain, tangerine peel, pit, salient point, bubble is less than 0.3mm, is no more than 3 places and at a distance of at least 5mm.
Ultrasonic sensor surface spraying paints hundred lattice adhesion:
Determinating reference: adopt ISO grade 1=ASTM grade, have small pieces to peel off in the intersection of otch, actual spoilage≤5% in Hua Ge district.Test meets " scratch experiment of GBT9286-1998 paint and varnish paint film " requirement.
Preferably, described two lead-in wires are wound around mutually.The mutual stranded winding after-current direction that goes between is on the contrary instantaneous, can reach counteracting, thus slacken the electromagnetic radiation in lead-in wire.
Preferably, described metal shell adopts aluminum alloy casing.Adopt aluminum alloy casing price low, reduce production cost; And aluminum alloy casing is when bonding with ultrasonic probe, bonding more firm, better with ultrasonic probe fiting effect.
Preferably, described radius of corner is 0.7mm.When radius of corner adopts 0.7mm, paint effectively can be avoided on the one hand to pile up in fillet place angulation, make metal shell surface smoothness better, more attractive in appearance on the other hand.
Preferably, described lead-in wire adopts graphene wire.Graphene wire is adopted easily to bend with the flexibility increasing electric conductivity and lead-in wire.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to the present invention, every according in technical spirit of the present invention to any simple modification, equivalent variations that above embodiment is done, all fall within protection scope of the present invention.
