specific Embodiment

[0032] A current sensor probe includes a support frame 1, an iron core 2, a winding and pins 3. The support frame 1 includes an upper cover 11 and a lower cover 12, the outer wall of the upper cover 11 is provided with a first protrusion 4, the first protrusion 4 exceeds the lower surface of the upper cover 11 and extends downward, and the outer side of the lower cover 12 The wall is provided with a second protrusion 6 at the position corresponding to the protrusion of the outer side wall of the upper cover 11, and the position where the first protrusion 4 extends downward beyond the lower surface of the upper cover 11 is provided to match the size of the second protrusion 6. The first hole 5 of the upper cover 11 and the lower cover 12 are snap-connected by the first hole 5 on the first protrusion 4 and the second protrusion 6 on the lower cover 12 to form an accommodating cavity. The shape of the support frame 1 is ring or square, and the shape of the iron core 1 is consiste...

Abstract

The invention provides a current sensor probe and an assembling method thereof. The probe comprises a supporting frame, iron cores, a winding and pins, wherein the supporting frame comprises an uppercover and a lower cover, the upper cover and the lower cover are connected to form an accommodating cavity, the iron cores are installed in the accommodating cavity, the winding is wound around the iron cores and the supporting frame, the pins are installed on the upper cover of the supporting frame, and wiring heads at two ends of the winding are connected with the pins. The probe is simple and convenient to assemble, the assembling efficiency of the probe is greatly improved, the production cost is reduced, meanwhile the supporting frame introduced into the probe forms a whole, movable partsare arranged in the probe, and the problem is solved that the winding is likely to break. In addition, the assembled probe serves as a whole and all the pins correspond in a one-to-one mode in finished product assembly and testing links, strenuous pin number distinguishing is not needed, probe and PCB assembly is facilitated, the pins are made of a hard metal material, a clamp can be used for testing, and the finished product assembling efficiency and testing efficiency are greatly improved.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a structure of a current sensor probe. Background technique [0002] The current sensor is used to measure the current. It is a sensor for secondary equipment such as measuring instruments and relay protection in the power system to obtain primary circuit current information. The function of converting the volume to the low pressure volume. Whether the current sensor works normally or not is of great significance to the safety, protection and measurement of the entire power system. [0003] The working principle is based on the magnetic modulation or fluxgate current sensor, which is the sensor with the highest measurement accuracy. Its structure can be divided into two parts: the probe and the control circuit (PCB board). The structure of the current sensor probe is relatively complicated. The most common structure is three iron cores and four windings. Each winding has two terminals, a...
