The invention relates to an integrated grounding piezoelectric fuze. The integrated grounding piezoelectric fuze comprises a signal processing circuit module, a signal output assembly, a shell, piezoelectric plates, a pre-tightening ring, an inertial mass block, insulating sheets, lead wire sheets, a positioning ring, lead wires, a pressing ring and an upper cover, wherein the signal processing circuit module is sealed inside the shell through an insulating damping material and is placed above the pressing ring; the pre-tightening ring is located between the pressing ring and the inertial mass block; two insulating sheets are arranged below the inertial mass block; the piezoelectric plates and the lead wire sheets are arranged between the two insulating sheets; signals of the piezoelectric plates are led out through the lead wire sheets connected with positive poles and negative poles of the piezoelectric plates; the signal processing circuit module and the lead wire sheets are connected through the lead wires; the signal output assembly is connected with the signal processing circuit module; and the signal processing circuit module comprises a comparator standard adjusting circuit, a comparing circuit, a silicon controlled rectifier Q1 and a standard source. The fuze has the characteristics of high reliability, fast response, small size, small weight, strong anti-impact capability and the like.

Description

technical field [0001] The invention relates to an integrated ground-contacting piezoelectric fuze, which belongs to the technical field of sensors. Background technique [0002] The fuze is an important part of ammunition. It uses environmental information and target information to detonate or ignite the control device of the warhead charge under predetermined conditions. effect. There are many types of fuzes, which can be roughly divided into three categories according to the mode of action and principle, namely trigger fuzes, time fuzes and proximity fuzes. Among them, the trigger fuze is still the most commonly used, and it is currently in extremely wide demand among all types of weapons. [0003] The impact piezoelectric fuze is mainly composed of a piezoelectric sensor and a signal processing circuit, which together constitute a trigger device. Piezoelectric sensors are generally composed of piezoelectric ceramics and mass blocks; signal processing circuits are used...

Problems solved by technology

For users, the split design has disadvantages such as inconvenient use and relatively cumbersome installation steps. At the same time, the split structure has the cable connection link from the sensor to the electronic switch, which increases unreliability. Problems such as poor contact of the plug-in, redundant objects, and failure of the plug-in spring cause failures, and even if a low-noise cable connection is used, it is also inevitable to bring in the influence of interference
