[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0020] like Figure 1-5 As shown, an ultrasonic transducer that is easy to install includes a transducer body 5 and a transducer housing 1. It is characterized in that one end of the transducer housing is open for mounting and fixing the transducer body 5, and the end surface of the transducer housing with the opening is symmetrically provided with a mounting structure, wherein:

[0021] A welding structure is installed on the mounting structure, and the wire 3 on the transducer body 5 is fixed and passes through the welding structure.

[0022] Furthermore, the installation structure is a placement groove 11 for the welding structural member to be embedded, installed and fixed.

[0023] Furthermore, the welding structural member is specifically a welding member 2 having a recess 21 , and the welding member 2 is further provided with a connecting ear 22 that is embedded in the placement groove 11 .

[0024] Furthermore, the outermost end of the connecting ear 22 extends out of the receiving slot 11 of the transducer housing, and the surface of the connecting ear 22 is flush with the end surface of the transducer housing 1. This allows the transducer to be better positioned against the test board, and the protruding portion of the connecting ear 22 is used for welding to the test board.

[0025] Furthermore, positioning holes 211 are provided on both sides of the center of the concave portion 21 of the welding member 2 for fixing the wires 3. This arrangement improves the position accuracy and centering of the wires 3 after the glue layer 4 is cured.

[0026] Furthermore, the potting glue at the opening of the transducer housing forms a potting layer 4, the lowest position of the potting layer 4 is slightly higher than the upper surface of the concave portion 21 of the welding part 2, which is the first surface A, and the highest position is lower than the upper surface of the connecting ear 22 of the welding part 2, which is the second surface B. In the above structure, if Figure 3 As shown, the lowest position of the glue-filling layer 4 is the first surface A in the figure, and the highest position is the second surface B.

[0027] Furthermore, the transducer housing 1 is cylindrical, and the two corners of the recess 21 of the welding piece 2 are 90 degrees, and the recess 21 of the welding piece 2 extends into the opening of the transducer housing.

[0028] The transducer is installed in this embodiment by aligning the recess 21 of the welding member 2 with the opening of the transducer housing 1, and its connecting ear 22 is snapped into the placement groove 11 so that the upper surface of the connecting ear 22 is flush with the end face of the transducer housing 1. The wire 3 of the transducer body 5 is positioned through the positioning hole 211 on the recess 21 of the welding member 2 and extends outward. After the above installation steps are completed, the opening of the transducer housing 1 is sealed with a tube glue to form a glue layer 4. Finally, the portion of the connecting ear 22 that extends beyond the placement groove 11 is welded and fixed to the test board.

[0029] Compared with the existing rubber sleeve and threaded fixing method, the transducer of the present application is more convenient to replace when replacing the transducer. It only needs to separate the transducer housing 1 and the welding part 2.

[0030] The technical solution of the above-mentioned utility model provides a solution that is significantly different from the existing technology to address the technical problem that the existing technology solution is too single. The parts not involved in the technical solution of this application are the same as the existing technology or can be implemented by using the existing technology, and will not be repeated here.

[0031] The technical solutions in the above embodiments have clearly and completely described the contents of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
