Problems solved by technology

And because the armature part 102 and the magnetic circuit part 101 need to be pressed into the base 201 at the same time, the difficulty of assembly is greatly improved and the efficiency of assembly is affected. The armature shafts 105 on both sides will inevitably interfere with the base 201 and scrape out dander, which greatly increases the risk of the relay not conducting

Embodiment 1

[0071] see Figure 5 to Figure 18 As shown, a magnetic latching relay with a double fixed frame magnetic circuit structure of the present invention includes a magnetic circuit part 1, an armature part 2 and a base 3; the magnetic circuit part 1 has a yoke 11, and the yoke 11 has two One is the upper and lower yokes, the two sides of the yoke 11 have a first boss 111, and the armature part 2 has a rotating shaft 21; it also includes a fixing frame 4, and the fixing frame 4 is provided with a first boss for matching with the magnetic circuit part. The fixing hole 41 of the table 111 and the rotating shaft hole 42 used to match the rotating shaft 21 of the armature part; the fixed frame 4 is two, respectively matched on both sides of the magnetic circuit part and the armature part to form a magnetic circuit system of an overall shape An assembly; an insertion structure is provided between the inner side of the two side walls 31 of the base and the corresponding fixing frame, and ...

Embodiment 2

[0094] see Figure 19 to Figure 26 As shown, a magnetic latching relay with a double fixed frame magnetic circuit structure of the present invention differs from the first embodiment in that the insertion structure is different. The insertion structure of this embodiment is arranged on the side wall of the base The inner side is the second vertical guide groove 33 and the outer surface of the fixed frame is the second vertical boss 46, and the second boss 46 of the fixed frame is vertically fitted on the base In the second guide groove 33.

[0095] Another difference is that the fixing hole 41 of the fixing frame used to fit the first boss 111 of the magnetic circuit part and the shaft hole 42 used to fit the shaft 21 of the armature part are both blind holes.

Embodiment 3

[0097] see Figure 27 to Figure 33 As shown, a magnetic latching relay with a double fixed frame magnetic circuit structure of the present invention differs from the first embodiment in that the insertion structure is different. The insertion structure of this embodiment is arranged on the side wall of the base The inner side is the third vertical boss 34 and the outer surface of the fixed frame is the third vertical guide groove 47, and the third guide groove 47 of the fixed frame is vertically fitted on the base In the third boss 34 of.

Abstract

The invention discloses a magnetic latching relay with a dual-holder magnetic circuit structure and an assembly method of the magnetic latching relay. The magnetic latching relay comprises a magnetic circuit part, an armature part and a base; the yoke of the magnetic circuit part is provided with a first lug boss, while the armature part is provided with a rotating shaft; the magnetic latching relay further comprises two holders; each holder is provided with a fixing hole for matching with the first lug boss of the magnetic circuit part and a rotating shaft hole for matching with the rotating shaft of the armature part; the two holders are matched with the two sides of the magnetic circuit part and the armature part to form an integrated magnetic circuit system assembly; insertion structures are arranged between the inner sides of the two sidewalls of the base and the corresponding holders; the magnetic circuit system assembly is assembled in the base by use of the insertion structures. According to the magnetic latching relay, the magnetic circuit part and the armature part are pre-assembled into the integrated structure by use of the holders, and consequently, the magnetic circuit part and the armature part can be mounted in the base very easily; on one hand, the assembly difficulty is greatly reduced, and on the other hand, the assembly chips also can be effectively avoided.
