Description

Technical Field

[0001] This utility model belongs to the field of relay technology, specifically relating to an armature assembly mounting structure and a relay. Background Technology

[0002] In the mounting structure of the armature assembly, the mounting method directly affects assembly efficiency and operational reliability. Currently common armature mounting schemes have the following drawbacks: Existing technology 1 (double-part fixed axis type): The structure employs a base body and an armature frame to jointly fix the armature shaft. During assembly, the armature must first be installed into the base, and then the armature frame is installed. The shaft center is formed by aligning the shaft holes of the base and the armature frame. It is evident that this solution involves a large number of parts (requiring an additional armature frame); after assembly, epoxy adhesive needs to be applied to the joint between the base and the armature frame and cured at high temperature, which is time-consuming; the shaft center accuracy depends on the alignment of the two parts, and accumulated tolerances reduce rotational reliability.

[0003] Existing technology two (through-pin type): A pair of shaft holes are provided on the base, and a corresponding shaft hole is made on the armature. A pivot is formed by inserting a pin through the shaft holes of the base and the armature. It can be seen that this solution requires additional assembly of the pin, which complicates the process; the pin is prone to loosening or falling off, resulting in insufficient stability in long-term use.

[0004] In summary, existing technologies suffer from low assembly efficiency and poor precision control due to their complex structures, and there is an urgent need for a new structure that simplifies the armature installation process and ensures rotational reliability. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide an armature assembly mounting structure, which uses an integrally formed rotating groove on the base and an elastic mounting buckle structure. During assembly, the armature shaft only needs to be pressed in one step to slide into the rotating groove (the mounting buckle automatically resets and locks after changing its shape). This eliminates the complex processes of armature frame assembly, glue curing, or shaft pin installation in the prior art, greatly shortening the assembly time and thus solving at least one of the technical problems involved in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is implemented as follows: An armature assembly mounting structure includes a base and an armature assembly, wherein a pair of rotating shafts are provided on both sides of the armature assembly; The base is provided with rotating grooves and mounting buckles on both sides corresponding to the rotating shaft; The rotating groove is used to accommodate the rotating shaft and limit its radial displacement; The mounting buckle has elastic deformation capability. During assembly, the rotating shaft slides over the mounting buckle, causing it to elastically deform outward. When the rotating shaft falls into the rotating groove, the mounting buckle resets and together with the rotating groove forms an axial limit, allowing the rotating shaft to rotate on the fixed axis.

[0007] Optionally, the rotating groove is an arc-shaped structure that fits into the rotating shaft.

[0008] Optionally, the rotating groove and mounting buckle extend to the edge of the base and are provided with guide grooves that narrow from wide to narrow.

[0009] Optionally, when the rotating shaft is assembled into the rotating groove through the guide groove, a gap is provided between the guide groove and the rotating shaft in the axial direction of the rotating shaft.

[0010] Optionally, the base of the mounting buckle is provided with a rounded corner or reinforcing rib to improve the structural strength of the mounting buckle.

[0011] Optionally, the narrow gap between the mounting buckle and the edge of the base is widened.

[0012] Optionally, the rotating groove, mounting buckle, and base are integrally injection molded structures.

[0013] This utility model also provides a relay, including the mounting structure of the armature assembly.

[0014] Optionally, the relay includes a coil assembly mounted on the base and located on one side of the armature assembly, and the rotating shaft is located on the other side of the armature assembly and is disposed opposite to the coil assembly. The coil assembly drives the armature assembly to rotate the rotating shaft in the rotating slot of the base.

[0015] Optionally, the relay further includes a housing, and the inner side of the housing is provided with a pair of limiting ribs; When the base and the outer shell are assembled in place, the limiting rib prevents the mounting buckle from deforming outward.

[0016] Compared with the prior art, the advantages of this utility model are as follows: (1) The present invention uses a rotating groove integrally formed base and an elastic mounting buckle structure. The armature shaft can slide into the rotating groove by pressing it in one step during assembly (the mounting buckle automatically resets and locks after changing the shape), eliminating the complex processes of armature frame assembly, glue curing or shaft pin installation in the background technology, and greatly shortening the assembly time.

[0017] (2) This utility model does not require additional armature frame, shaft pin or adhesive material. The base integrates the functional structure of rotating groove, mounting buckle and guide groove, reducing the number of parts and reducing material cost and management cost.

[0018] (3) The rotating groove and the mounting buckle of this utility model are integrally injection molded on the base, avoiding the shaft fit error caused by the assembly of multiple parts in the background technology, and ensuring the consistency of the rotation trajectory of the armature shaft; the rotating groove adopts an arc design that fits the armature shaft, increasing the contact area, reducing wear, and improving the mechanical life; the outer shell limiting rib prevents the mounting buckle from deforming outward after assembly, preventing the armature shaft from dislodging under impact and vibration, and enhancing long-term stability.

[0019] (4) The mounting buckle of this utility model is equipped with rounded corners or reinforcing ribs to avoid stress concentration and fracture during elastic deformation; the bend between the mounting buckle and the base edge is widened to improve mold life and injection molding yield.

[0020] (5) The guide groove of this utility model has a gradient design from wide to narrow to guide the armature shaft to slide accurately into the rotating groove, reducing the assembly difficulty and adapting to the needs of automated production. Attached Figure Description

[0024] Please see Figures 1 to 8 As shown, this utility model embodiment provides an armature assembly mounting structure, including a base 1 and an armature assembly 2.

[0025] Combined Figure 3 and Figure 6 As shown, the armature assembly 2 has a pair of rotating shafts 21 on both sides, and the base 1 has a rotating groove 11 and a mounting buckle 12 on both sides corresponding to the rotating shafts 21.

[0026] The rotating groove 11 is used to accommodate the rotating shaft 21 and limit its radial displacement.

[0027] The mounting buckle 12 has elastic deformation capability. During assembly, the rotating shaft 21 slides over the mounting buckle 12 to cause it to elastically deform outward. When the rotating shaft 21 falls into the rotating groove 11, the mounting buckle 12 resets and forms an axial limit together with the rotating groove 11, so that the rotating shaft 21 rotates on the fixed axis.

[0028] The rotating groove 11 is an arc-shaped structure that fits into the rotating shaft 21, which increases the contact area, reduces wear, and extends the mechanical life.

[0029] Combined Figure 4 As shown, the rotating groove 11 and the mounting buckle 12 extend to the edge of the base 1 and are provided with a guide groove 13 that gradually narrows from wide to narrow, so that the rotating shaft 21 can slide into the assembly position of the rotating groove 11 better, reducing the assembly difficulty and adapting to the needs of automated production.

[0030] When the rotating shaft 21 is assembled into the rotating groove 11 through the guide groove 13, a gap is provided between the guide groove 13 and the rotating shaft 21 in the axial direction of the rotating shaft 21.

[0031] The narrow gap 14 between the mounting buckle 12 and the edge of the base 1 is widened to improve mold life and injection molding yield.

[0032] Combined Figure 5 As shown, the base of the mounting buckle 12 is provided with a rounded corner 121 or a reinforcing rib to avoid stress concentration and breakage during elastic deformation.

[0033] The rotating groove 11, mounting buckle 12 and base 1 are integrally injection molded structures, which avoids the shaft fit error caused by the assembly of multiple parts and ensures the consistency of the armature shaft rotation trajectory.

[0034] This utility model also provides a relay, including the mounting structure of the armature assembly, and further including a housing 3, a coil assembly 4, a push plate 5, a moving contact assembly 6, and a stationary contact assembly 7.

[0035] Combined Figure 7 and Figure 8 As shown, the inner side of the outer shell 3 is provided with a pair of limiting ribs 31. When the base 1 and the outer shell 3 are assembled in place, the limiting ribs 31 prevent the mounting buckle 12 from deforming outward, preventing the armature shaft from dislodging under impact and vibration, and enhancing long-term stability.

[0036] The base 1 and the outer shell 3 are assembled to form a receiving space for assembling the armature assembly 2, coil assembly 4, push plate 5, moving contact assembly 6 and stationary contact assembly 7.

[0037] Combined Figure 1 and Figure 2 As shown, the moving contact assembly 6 cooperates with the stationary contact assembly 7. One end of the pusher plate 5 is connected to the moving contact assembly 6, and the other end is connected to the armature assembly 2. The coil assembly 4 drives the armature assembly 2 to rotate, thereby driving the moving contact assembly 6 to move through the pusher plate 5, realizing the closing / opening of the moving contact assembly 6 and the stationary contact assembly 7.

[0038] The coil assembly 4 is mounted on the base 1 and located on one side of the armature assembly 2. The rotating shaft 21 is located on the other side of the armature assembly 2 and is arranged opposite to the coil assembly 4. The coil assembly 4 drives the armature assembly 2 so that the rotating shaft 21 rotates in the rotating groove 11 of the base 1.
