Abstract

This invention for assembly of brick SMD reed switch , apply for various type of glass reed switch ,including a reed switch, a shield tube(could be plastic or ceramic material) which for protect the glass reed switch, outer shape is square and inner shape is round or polygons, two square electrodes , one side is a square cap , by protect the glass reed switch, two-side connectied square electrodes, electrodes inner width and height dimension are equal to the outer width and height dimension of shield tube, with a bulge corresponding to inner shape of shield tube in the central, each electrode contain a thought hole right in the middle, also a semicircle by the end of through hole on the outer side on each electrode to fill solder paste for conjunction of electrode and reed switch terminal. This invention use shield tube to protect the reed switch for avoid glass body break, also use external electrodes to replace the press procedure on the reed switch terminal which always break the glass easily but cant create too much size of solder pad, to assembly a new type of brick reed switch , efficiently shift the yield and the contact area with the solder pad on PCB?

V. New description: [New technical field] This creation is about the sealing method of a glass reed switch, especially an easy to assemble 'and effectively increase the contact area with the circuit board on the paste type 5 process. Square reed switch. [Prior Art] Since the magnetic spring is made of a glass casing, the most common problem of the surface reed is the damage problem, especially the more the wire is now facing the surface (10). The glass spring _ depends on the surface rotation (10) _ type, the contact stress is not easy to handle 'cause the main body to damage the high and high, in order to prevent this problem on the market, is to switch the package Di, currently there is _ way, the kind is the reed switch to the plastic embedded in the person (such as Figure 1), but due to the extremely high pressure of the secret injection, the yield is not improved, there is also a flap cover, and then dried with soft lining (pictured), the shortcomings of the short-term _ wealth channel The pin is placed, > easy to machine out, and the melting point of the soft rubber is too low. The above-mentioned package surface adhesion process is to fix the material with solder paste and pass the high temperature tin furnace to achieve the magnetic force. The switch is a round pin. Even if the above package method is used to solve the problem of breakage of the switch, the solder area of the surface is too small to be solved. The round type (10), regardless of how to punch, has to reach a sufficient area, based on physics. Characteristic _ And the red channel pressure is too strong, it will cause damage _ worries. (Figure 3) 4 M397584 [New content] • f og correction 卞 >! I < -- , 3-___ This creation provides a reed switch with a reed switch, including a magnetic spring The switch, a sleeve for protecting the glass reed switch, externally square, the inside is circular or polygonal, two square electrodes, one side is a groove, the inner length and width dimensions are equivalent to the outer length and width of the sleeve, and there is a corresponding The inner shape of the sleeve is convex, and the center has a hole. The perforation is on the outside and a small groove is left for the electrode to be soldered to the switch pin solder paste.

The creation of the bribe officially protects the body, and the electrode of the meal replaces the stamping that may cause damage but does not have much effect. It is formed into a block type magnetic cyanine switch, which effectively improves the manufacturing phase and the contact area with the circuit board. [Embodiment] Please refer to Figure 4, Figure 6, and Zhuang. The block-type reed switch of this series-Saki switch package is applicable to all kinds of round-shaped glass tube magneto-phthalmic switches, including one.

The protective sleeve of the protective glass reed switch has a shape 5 inside the protective sleeve (outside: or polygon) 52' two bungee poles 53, the side is the gorge 54 of the corresponding sleeve, and the center has a perforation 55, and the perforation is The outer side of the semicircular groove 56 on the outer side of the central perforation of the electrode is used for soldering the electrode contact switch pin 57 solder paste. First use the self-coffee W1_57 (four) =: thick length, placed in the protective casing (10) square circle or more: opening force 2, then the circular glass tube magnetic switch (10) 5 55, and in the perforated oblique ship stay (four) pole The center hole 56 is filled with solder paste, and then placed on the outer side of the semicircular grooved baking tray, and the electrode and the round glass 5 M397584 tube reed switch pin 57 are welded.
