A pressure sensor access device

Abstract

The invention provides a pressure sensor storing and taking device. The pressure sensor storing and taking device comprises a box-like substrate, wherein a separating layer is arranged inside a storage space of the substrate; the separating layer divides the storage space of the substrate into a functional zone protecting compartment and a wire harness protecting compartment which are transversely arranged in parallel; a plurality of clamping slots are formed in the radial direction of the separating layer; the separating layer separates a functional zone of a pressure sensor from a conductive wire and a plug so as to avoid the conductive wire and the plug from pressing the functional zone; an arranged layering protective plate is used for layering and separating the functional zone so as to prevent mutual pressing of an upper layer and a lower layer of the functional zone; an arranged conductive wire fixing layer further protects an interface area and prevents the plug from destroying the interface area. The pressure sensor storing and taking device effectively protects each part of the pressure sensor from being pressed, and the pressure sensor can be put into the pressure sensor storing and taking device tidily and can be stored and taken conveniently, so that the unqualified rate is reduced and the pressure sensor storing and taking device can be repeatedly used and is suitable for pressure sensors with various sizes.

Description

Technical field [0001] The invention belongs to the field of access protection devices, and particularly relates to a reusable access device. Background technique [0002] In the automotive field, for the safety of passengers, a seat belt warning system is usually installed. After a passenger sits on a car seat, if the seat belt is not worn, the car will often send an automatic alarm, usually in the form of light or sound. In the seat belt alarm system, the core component is the soft pressure sensor. [0003] The pressure sensor is placed between the foam of the seat and the mask, which is easy to squeeze and deform. The signal comes from the person riding, and the person's own weight squeezes the pressure sensor to generate a continuous resistance signal to activate the alarm system. [0004] The soft pressure sensor is mainly composed of functional areas, loop areas, wires, interface areas and plugs formed by overlapping activation layers, carbon layers, metal layers, and protecti...

AI Technical Summary

Problems solved by technology

[0004] Soft pressure sensor is mainly composed of active layer, carbon layer, metal layer and functional area formed by overlapping protective layers, loop area, wire, interface area and plug. Among them, the most important functional area and interface area are very easy to transport, It is squeezed and deformed during the taking process, causing the internal circuit to break and fail

[0005] At present, in terms of access to this type of pressure sensor on the market, it is only simple to protect the functional area with bubble plastic. The pressure sensor is scattered and stored, and the wires are prone to cross winding, which makes it inconvenient to take, and the bubble plastic cannot be recycled.

Or, use rubber bands to bind a certain number of sensors, which cannot protect the interface area, is prone to disconnection, and is also difficult to handle

[0006] For a large number of pressure sensors, the pressure sensors are simply wrapped in a carton at present, and the products are squeezed against each other, which is easy to damage the functional area, and the product failure rate is high.

[0007] The above various access tools are disposable and cannot be recycled, resulting in a large waste of resources
