The shortcoming of above-mentioned this mounting structure is: directly be connected by connector 4 between guidance panel 2 and the transducer body 1, in that being inserted, guidance panel 2 installs or when using guidance panel 2 to operate, the stressed connector 4 that is welded on guidance panel 2 backs that directly acts on, and on the socket on the transducer body 13, may cause weld to split, cause transducer body 1 operation irregularity; In addition, when guidance panel 2 was installed to transducer body 1, the socket 3 in the installation groove that is difficult for making connector 4 aim at transducer body 1 was installed relatively difficulty, if insert by force under out-of-alignment situation, then may cause socket 3 and connector 4 to damage.

The utility model content

The technical problems to be solved in the utility model is, a kind of mounting structure of frequency converter guidance panel is provided, and makes things convenient for the installation between frequency converter guidance panel and the transducer body.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of mounting structure of frequency converter guidance panel, on transducer body, be provided with the installation groove that inserts for guidance panel, in described installation groove, be provided with socket, be provided with the connector that is complementary with described socket at the back of guidance panel, described connector inserts the detachable installation that socket is realized guidance panel and transducer body, on two sides of described guidance panel, be respectively equipped with at least one gathering sill, on two sidewalls of described installation groove, be respectively equipped with the guiding projection that is complementary with above-mentioned gathering sill.

As preferably, being shaped as of the described gathering sill in the above-mentioned mounting structure is trapezoidal, and being shaped as of described guiding projection is trapezoidal.

As further improving, on two sidewalls of the installation groove on the described transducer body, be respectively equipped with at least one Elastic buckle, on two sides of described guidance panel, be respectively equipped with the draw-in groove that is complementary with described Elastic buckle.

Compared with prior art, the mounting structure of the frequency converter guidance panel that provides of the utility model has the following advantages:

(1) on the sidewall of the installation groove of the side of guidance panel and transducer body, be provided with the gathering sill and the guiding projection that are complementary, this guide frame, bootable guidance panel reaches installation site accurately, has made things convenient for the accurate installation between guidance panel and the transducer body;

(2) insert in the installation process at guidance panel, guide frame also can progressively improve the frictional force on guidance panel and the transducer body contact-making surface, has avoided guidance panel to insert impulsive force excessive when putting in place, and the protection connector is not damaged;

(3) when using the guidance panel that has been installed on the transducer body to operate, conjunction surface between guiding projection and the gathering sill, can bear certain active force, thereby peptizaiton stressed on connector and socket can be protected the printed circuit board (PCB) of connector, socket and welding socket;

(4) on the sidewall of the side of guidance panel and the installation groove on the transducer body shell, be provided with the Elastic buckle and the draw-in groove structure that are complementary, guidance panel accurately is fixed on the transducer body reliably, guaranteed the mounting structure between the guidance panel and transducer body and the stability of signal conduction in the use.
