Description

Breakage-proof structure of lead-out wire of linear displacement sensor

Technical Field

The utility model belongs to the design technology of linear displacement sensors, and relates to an improved lead-out structure of a lead-out wire of a linear displacement sensor.

Background

For the wire displacement sensor adopting the outgoing line output mode, the commonly used outgoing line leading-out mode is that a plurality of outgoing lines are concentrated on one side of a coil and led out side by side, an insulating sleeve is sleeved on the outgoing lines and the welding spots of enameled wires and is firmly bound by binding wires, and the outgoing lines have a section of radian or bending along the axial direction when the binding and fixing are carried out. Although the lead-out mode has a certain effect on preventing the lead-out wire from being broken due to pulling of external force, the reliability is not high, and the function failure of the bending structure can be caused by loosening of the binding wire or excessive external force after long-term use. Therefore, a new anti-breaking structure for the outgoing line of the linear displacement sensor is required, which can effectively solve the problems.

Disclosure of Invention

The purpose of the utility model is: a novel outgoing line breakage-proof structure of the linear displacement sensor is designed to solve the problems.

In order to solve the technical problem, the technical scheme of the utility model is as follows:

the utility model provides a structure is prevented absolutely by line displacement sensor lead-out wire, the structure is prevented absolutely by the lead-out wire for a wiring skeleton of outlet end design. Two layers of wire outlet grooves are arranged on the wiring framework in parallel.

The number of the outgoing line notches is the same as that of the outgoing lines.

The thickness of the second layer of wire outlet grooves is larger than that of the first layer of wire outlet grooves, the second layer of wire outlet grooves are positioned at the tail ends, and the second layer of wire outlet grooves positioned at the tail ends bear the tensile force of the transferred outgoing wires.

The outlet notches of the two layers of outlet grooves are aligned and uniformly distributed along the circumference.

Each outgoing line is provided with an outgoing line notch corresponding to the outgoing line.

And leading out wires out sequentially through the two layers of wire outlet grooves in a staggered groove mode.

The linear distance between the two layers of the outgoing line grooves is 2-3 times of the outer diameter of the outgoing line.

The height of the outlet notch is not less than 3 times of the outer diameter of the outgoing line.

The utility model has the beneficial effects that:

the novel lead-out wire breakage-proof structure of the linear displacement sensor is provided, each lead-out wire is led out through the structure of the coil framework in an independent staggered groove mode, and the stress position of the lead-out wire when the lead-out wire is pulled by external force can be transferred to the lead-out wire at the rear end from the welding point of the lead-out wire. The structural strength of lead-out wire itself is far greater than the intensity of solder joint, so this novel structure is prevented absolutely can reduce external force and pull the cracked possibility of lead-out wire solder joint. The tensile capacity of the sensor leading-out structure is effectively improved, the product strength is optimized, the product failure rate is reduced, the product reliability is improved, and the sensor leading-out structure is more suitable for aviation equipment products.
