Abstract
The utility model discloses a waterproof ultrasonic probe comprising a housing, a sensor, and a PCB. The sensor is disposed in the housing, and one end of the sensor is exposed out of the housing. The sensor is connected with the PCB in the housing by a connecting lead. The housing and the sensor are connected together in a sealed manner by a silica gel sealing member, and the silica gel sealing member and the outer housing wall of the sensor are sealed by two sealing rings. The waterproof ultrasonic probe is advantageous in that the sensor and the housing are sealed by adopting the silica gel sealing member having two sealing rings, and therefore the moisture can be effectively prevented from leaking from the front end of the sensor to the inner side of the probe, the damage on the inner elements caused by the moisture can be prevented, and the service lifetime of the probe can be prolonged.
Description
[technical field]
The utility model relates to ultrasonic probe structural design, relates in particular to the design to hyperacoustic waterproof construction.
[background technology]
Ultrasonic probe, for carbody shell, is directly exposed in external environment, and working environment can face the factor invasion and attack such as rainwater humidity.In daily use, unavoidably can run into the situation of moisture, moisture content infiltration, if the front end of probe does not design waterproof or waterproof effect is bad, can cause the inner infiltration of probe, affect internal circuit, corrode and damage thereby cause internal component to be subject to moisture.Some components and parts need to be worked under dry environment, does not work or under low temperature environment, error message occurs once make moist to damage, and brings very large puzzlement to user.Be necessary to solve the waterproof problem of ultrasonic probe, guarantee that serviceable life and the effect of ultrasonic probe reaches expected design.
[summary of the invention]
The utility model has proposed the ultrasonic probe of good water-proof effect, long service life for above problem.
The related ultrasonic probe of the utility model comprises housing, sensor, pcb board, the mode that this sensor exposes with one end is installed in housing, sensor is connected with the pcb board in housing by connecting wire, it is characterized in that, between housing and sensor, seal installation by silicone-rubber seals, between this silicone-rubber seals and sensor outer housing wall, seal by two seals circle.
This silicone-rubber seals is the wide-aperture circular lid structure of small-bore, one end other end, and internal diameter and the sensor external diameter of one end, large aperture of silicone-rubber seals adapt, and this silicone-rubber seals is enclosed within on sensor with its one end, large aperture.
On the inwall of one end, large aperture of silicone-rubber seals, have the O-ring seal of twice projection, and on the outer wall of sensor, have two seals groove, sealing circle correspondence is pressed in seal groove.
Be perfused with in the enclosure casting glue.
The utility model is adopting the silicone-rubber seals with two seals circle to the sealing between sensor and shell, effectively intercepted moisture and penetrated into probe inside from sensor front end, prevents that moisture from causing damage to internal component, extends the serviceable life of probe.

[embodiment]
Below in conjunction with drawings and Examples, the utility model water proof type ultrasonic probe is elaborated.
Please refer to accompanying drawing 1: wherein show ultrasonic probe, this probe comprises housing 10, sensor 20, pcb board 30, the mode that this sensor 20 exposes with one end is installed in housing 10, sensor 20 is connected with the pcb board 20 in housing by connecting wire 40, between housing 10 and sensor 20, seal installation by silicone-rubber seals 60, between this silicone-rubber seals 60 and sensor 20 shell walls, seal by two seals circle.The front end of this sensor carries out waterproof sealing by silicone-rubber seals 60, and its be encased in housing 10 rear end seal by casting glue 50, in the interior clearance spaces of housing 10, pour into casting glue and carry out hermetically sealed.
This silicone-rubber seals 60 is the wide-aperture circular lid structures of small-bore, one end other end, and the internal diameter of one end, large aperture of silicone-rubber seals 60 and sensor 20 external diameters adapt, and this silicone-rubber seals is enclosed within on sensor with its one end, large aperture.
On the inwall of one end, large aperture of silicone-rubber seals, there is the O-ring seal of twice projection, respectively the first O-ring seal 61 and the second O-ring seal 62, be provided with two seals groove and there is correspondence on the outer wall of sensor, respectively the first seal groove 21 and the second seal groove 22, the degree of depth of this first/the second seal groove and width and O-ring seal adapt, in installing, first by installation of sensors in silicone-rubber seals, the two seals circle of this silicone-rubber seals is pressed into respectively in the two seals groove of sensor wall, forms waterproof closely and blocks.And then silicone-rubber seals is installed in housing to the assembling having formed.
The utility model is adopting the silicone-rubber seals with two seals circle to the sealing between sensor and shell, effectively intercepted moisture and penetrated into probe inside from sensor front end, prevents that moisture from causing damage to internal component, extends the serviceable life of probe.
The above, it is only the utility model preferred embodiment, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, but not in order to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be not depart from technical solutions of the utility model content, refer to any simple modification that above embodiment is done according to the utility model technology, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
