Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-4, an ultrasonic driver with a special structure comprises a bottom cover 1, a PCB 2 and a face cover 3, wherein the PCB 2 is disposed in a cavity covered between the bottom cover 1 and the face cover 3, two ends of the bottom cover 1 and the face cover 3 are respectively provided with a wire inlet 4, and a waterproof silica gel block 5 is disposed at the wire inlet 4; wiring holes 6 corresponding to the wire outlet holes are respectively arranged at two ends of the face cover 3, and the wiring holes 6 are covered by waterproof silica gel covers 7; the wire inlet hole 4 is connected with the waterproof silica gel block 5 and the wire connecting hole 6 is connected with the waterproof silica gel cover 7 in a sealing mode through ultrasonic waves. The wire inlet hole 4 is sealed with waterproof silica gel block 5 to the ultrasonic wave, will connect the line hole 6 sealed with waterproof silica gel lid 7 to sealed effect is better than glue, also uses for a long time and can not age. The wire gets into from the line hole of waterproof silica gel piece 5 to the entering tip of wire is provided with binding post, fixes binding post on connector 12 through wiring hole 6, and fixed mode can be for twisting the screw fixation.
The wiring hole 6 is provided with limiting blocks 8 on two sides, a sealing ear cover 9 is arranged between the limiting blocks 8, and the wiring hole 6 is covered by the sealing ear cover 9. The thickness wall limiting block 8 of the sealing ear cover 9 is large in thickness, and the sealing effect is improved through extrusion of the waterproof silica gel cover 7.
The inner side of the waterproof silica gel cover 7 is provided with a limiting groove 10, when the waterproof silica gel cover 7 covers the wiring hole 6, the limiting block 8 is arranged in the limiting groove 10 and can limit the looseness of the waterproof silica gel cover 7.
