A is the adhering part and the glass adhering surface, B is the adhering part, C is the external force supporting part, D is the external force stress point, and E is the sealing part. The sintering mode adopted by the existing products in the current market is coil heating sintering, the structure of sealing tube sintering is a conical structure, the area of a close part and a glass binding face A is small, and a lead is tinned.
The structure of the prior product has the following defects:
the head is sintered to be sharp, the stress is poor, and the glass is fragile when the glass falls off;
sharp corners and uneven appearance are easy to appear in sintering;
when the product is cut or bent in the subsequent process, the stress borne by the reed is transmitted to a sintering part, because the bonding area of the sintered close part and the glass is small, and because the stress point direction of the glass tube of the conical structure is an oblique angle, according to the principle of force and force arm, the glass tube is easy to cause the close part B to generate a gap under the action of oblique angle stress, so that nitrogen is leaked, even the glass tube is easy to crack, and the effect of a magnetic reed switch is lost;
the reed tinned wire has relatively poor contact resistance and conductivity and is easy to oxidize.
