Assembled side-outlet flexible-connection velocity sensor

Abstract

The invention relates to a velocity sensor, in particular to an assembled side-outlet flexible-connection velocity sensor which comprises a casing and a closure plate. The casing and the closure plate are combined to form an internal cavity, and a circuit board and flexible connection wires are arranged in the cavity. A boss is horizontally arranged at the position, close to the top surface of the casing, of one side surface of the casing, and is provided with a metal joint horizontally. A cable connected with the circuit board penetrates the metal joint to extend out of the cavity. A sealing rubber sheath is arranged between the inner side of the metal joint and the cable. A probe is mounted at the bottom of the casing and is connected with the circuit board through the flexible connection wires. A sealing pad is sandwiched between the casing and the closure plate. A manufacturing method of the velocity sensor is optimized by means of structural modification, and the technical problems of incapability of reuse and difficulty in repairing when the velocity sensor is in fault are solved.

Description

Technical field [0001] The invention relates to a speed sensor, in particular to an assembled side outlet soft connection speed sensor. Background technique [0002] At present, the Hall speed sensor mounted on the back is favored by sensor users due to its simplicity, easy operation and small footprint, and has been widely used. Due to the diverse manufacturing processes of the speed sensor, and when the speed sensor is used, the speed measurement accuracy and dustproof and waterproof requirements of the sensor are high. Therefore, in the structural design of the speed sensor, it is necessary to consider simplifying the speed sensor under the premise of meeting the requirements for dust and waterproof The problem of the production process. Most of the speed sensors used in the prior art adopt a sealing fastening method in which the wire is discharged at the tail of the speed sensor, and the connection with the cable is compressed and potted. The shell is integrated, and the cir...
