Embodiment Construction

[0028] Such as figure 1 , figure 2 and image 3 As shown, the combined resonator of the present invention includes a housing 1, which is a cuboid insulator, which can be made of plastics, ceramics and other materials with good insulation properties. In this embodiment, it is a plastic product. Said shell 1 is in a closed shape, and a support frame 8 is arranged therein. The supporting frame 8 is a cuboid insulator, which is a plastic product, and a large surface thereof is processed with a pit 7 . The pit 7 is rectangular, and the opposite side of the bottom, ie, two ends of the bottom, are each fixed with a copper sheet used as an electrode lead 9 . Two lead pins 2 are arranged on the outside of the shell 1, and the two electrode leads 9 in the pit 7 of the support frame 8 pass through the support frame 8 and the shell 1 in turn and are connected with the two lead pins 2 outside the shell 1 respectively.

[0029] A piezoelectric chip is arranged inside the supporting fra...

Abstract

The invention discloses a combined type resonator, in particular to a combined type piezoelectric ceramic resonator which comprises a shell and a supporting frame arranged in the shell, wherein two leading wire feet are arranged outside the shell, one surface of the supporting frame is provided with a concave pit, opposite edges of the bottom of the concave pit are both provided with electrode leading wires, and the two electrode leading wires are respectively connected with the two leading wire feet, and the supporting frame is internally provided with a piezoelectric chip which is pressed by a gland bush. The combined type piezoelectric ceramic resonator is characterized in that one surface of the piezoelectric chip is provided with a base plate, an electrode layer is positioned between the base plate and one surface of a support base of the piezoelectric chip to form an integer, the other surface of the piezoelectric chip is also provided with the electrode layer which is divided into two parts, the two parts are respectively connected with the two electrode leading wires, and a part of the electrode layer is connected with the electrode layer positioned between the piezoelectric support base and the base plate. The combined type piezoelectric ceramic resonator is used for replacing an LC circuit inside an ink box of a printer so that the ink box can be compatible for multi-type printers, thereby having more extensive range.

Description

technical field [0001] The invention relates to an electronic component. Specifically, it is a combined piezoelectric ceramic resonator. Background technique [0002] At present, it is known in the printer manufacturing industry that LC circuits are installed in the ink cartridges of printers with the function of measuring the ink remaining in the ink cartridges. Wherein, two terminals of the LC circuit are respectively connected with two control ports SA and SB on the main control circuit board of the printer. When working, the main control circuit board alternately outputs a rated excitation pulse signal (such as +38V) to the two terminals of the LC circuit to generate a pulse signal corresponding to the characteristic curve. When the excitation pulse signal is output from one control terminal SA of the main control circuit, processed by the LC circuit, input to the other control terminal SB of the main control circuit, or output from one control terminal SB of the main ...
