Description
Technical field
The present invention relates to tongue tubes to produce and process technical field, the dry spring canister and tongue tube of specifically a kind of flow switch
Packaging technology.
Background technique
Tongue tube is also referred to as reed capsule or magnetic reed switch, is a kind of special key of magnetosensitive, is dry-reed relay and close to opening
The main component of pass.The working principle of tongue tube is: its two internal contact spring is by magnetic attraction, so that external electrical is returned
Road conducting, position is horizontal between contact spring and magnet, and contact resistance is smaller, and contact effect is also better.
The encapsulation of tongue tube can be all related in the production process of magnetic flow switch, traditional handicraft is by tongue tube
It is inserted directly into dry spring canister and is packaged, two for not can guarantee tongue tube in this way are horizontal position between reed and magnet, separately
The depth of outer tongue tube insertion dry spring canister not can guarantee yet, consistency is poor, will affect the sensitive of flow switch over time
Degree eventually leads to flow switch failure.
Summary of the invention
It is above-mentioned to solve the purpose of the present invention is to provide a kind of dry spring canister of flow switch and tongue tube packaging technology
The problem of being proposed in background technique.
To achieve the above object, the invention provides the following technical scheme:
A kind of dry spring canister of flow switch, including pipe sleeve ontology, the pipe sleeve body interior are equipped with mistake proofing limited step.
As a further solution of the present invention: pipe sleeve ontology front end portion aperture is big, and rear end part aperture is small.
As a further solution of the present invention: described this body section of pipe sleeve has two kinds of O type cross section or D type section.
A kind of tongue tube packaging technology of flow switch, includes the following steps:
Step 1: tongue tube both ends pin being welded on PCB along 90 ° of bending of contact spring horizontal direction tooling, so that contact
Reed and pcb board are in horizontal parallel state；
Step 2: the dry spring canister being increased into mistake proofing limited step in design, and according to tongue tube and pcb board welding assembly
Whole height afterwards determines dry spring casing diameter, and dry spring canister front section aperture is big, and hindfoot portion aperture is small, prevents
Pcb board wrong plug (if wrong plug direction, can not be entirely insertable)；
Step 3: colloid will be injected in the dry spring canister in step 2, the pcb board that postwelding is welded in step 1 is fully inserted into tongue tube
In set, i.e. encapsulation is completed after colloid solidification.
As further scheme of the invention: colloid used in the step 3 is epoxy resin.
Compared with prior art, the beneficial effects of the present invention are:
A kind of dry spring canister of the flow switch, it is structurally reasonable, it is novel in design, optimize dry spring canister structure, increases mistake proofing limit
Position step, both ensure that insertion depth of the tongue tube in dry spring canister, and had substantially increased consistency, while also avoiding PCB
The generation of plate wrong plug phenomenon, while using this special package technique, it can be ensured that it is in always between the reed and magnet of tongue tube
Horizontal parallel relationship, switch jaw contact is more preferable after actuation, but also the depth of tongue tube insertion dry spring canister is guaranteed, unanimously
Property greatly improves, and ensure that the sensitivity of switch, extends switch service life, practical.
