Abstract
The utility model discloses an armature iron of a magnetic latching relay. The armature iron comprises a shell made of plastic, a permanent magnet and two armature pieces which are installed in the shell and a push block which is fixedly installed on the shell. The two armature pieces are parallel to each other and are at two ends of the permanent magnet. Two ends of the armature pieces extend out of the shell. The shell comprises a shell body and a shell cover which is buckled on the shell body. The edge of the shell cover is provided with a plurality of buckles. The edge of the shell body is provided with a plurality of clamping grooves, and the clamping grooves and the buckles are mutually buckled. According to the armature iron, the shell is installed outside the permanent magnet and the armature pieces in a clamping mode, the armature iron has the advantages of simple structure and convenient installation, a cylindrical structure is employed by a push rod, thus line contact is employed by the push rod and a connection piece, and the stability in use is ensured.
Description
Technical field
The utility model relates to a kind of relay, is specifically related to a kind of armature of magnetic latching relay.
Background technology
Relay is a kind of electric control device.It has control system and by the interactive relationship between control system.Conventionally be applied in the control circuit of automation, it is actually a kind of " automatic switch " that goes to control large electric current running with little electric current.Therefore play the effects such as automatic adjusting, safeguard protection, change-over circuit in circuit.
Wherein, the normally closed or normally open of magnetic latching relay is the effect that relies on permanent-magnet steel completely, and the armature of magnetic latching relay comprises plastic casing, is arranged on armature plate and permanent magnet in plastic casing, and is arranged on the push rod on shell; During work, by coil electricity, then act on armature, thereby make push rod drive brace to move by the rotation of armature self, realize the on-off action of contact.But plastic casing integrated injection molding is in the outside of armature plate and permanent magnet, cause armature processing cumbersome, and the molten plastic of high temperature may cause damage to permanent magnet and armature plate during injection moulding.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to provide a kind of armature of magnetic latching relay simple in structure, easy for installation.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of armature of magnetic latching relay, it comprises the shell being made of plastics, permanent magnet and armature plate are in the enclosure installed, and be fixedly mounted on the pushing block on shell, armature plate is two, and two armature plates are parallel to each other and are positioned at the two ends of permanent magnet, and shell is all stretched out at the two ends of armature plate; Shell comprises housing and be fastened on the cap on housing, and the edge of cap is provided with a plurality of buckles, and the edge of housing is provided with a plurality of draw-in grooves that mutually fasten with buckle.
Wherein, in shell, be provided with reference column, on permanent magnet, be provided with the location hole that holds reference column.
Wherein, be coaxially arranged with shaft hole on reference column, the two ends of shaft hole are all connected with rotating shaft.
Wherein, the head of pushing block is provided with push rod, and push rod is cylindrical.
Wherein, on pushing block, be provided with a plurality of deep floors.
Wherein, on shell, be provided with balancing weight.
(3) beneficial effect
Compared with prior art, the shell of the utility model armature adopts the mode of buckle to be arranged on outside permanent magnet and armature plate, has feature simple in structure, easy for installation; And push rod adopts cylindrical structural, make to adopt line contact between push rod and brace the stability while having guaranteed use.
Accompanying drawing explanation
Fig. 1 is the three-dimensional exploded perspective view of the armature of the utility model magnetic latching relay.
Fig. 2 is the three-dimensional exploded perspective view of the armature other direction of the utility model magnetic latching relay.
Fig. 3 is the Facad structure schematic diagram of the armature of the utility model magnetic latching relay.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The stereochemical structure of the armature of the utility model magnetic latching relay as depicted in figs. 1 and 2, its Facad structure as shown in Figure 3, the armature of this magnetic latching relay comprises the shell 2 being made of plastics, be arranged on permanent magnet 4 and armature plate 3 in shell 2, and be fixedly mounted on the pushing block 6 on shell 2, armature plate 3 is two, and two armature plates 3 are parallel to each other and are positioned at the two ends of permanent magnet 4, and shell 2 is all stretched out at the two ends of armature plate 3; Shell 2 comprises housing 22 and is fastened on the cap 21 on housing 22, and the edge of cap is provided with a plurality of buckles 211, and the edge of housing 22 is provided with a plurality of draw-in grooves 223 that mutually fasten with buckle 211.This shell adopts the mode of buckle to be arranged on outside permanent magnet and armature plate, has feature simple in structure, easy for installation.
In shell 2, be provided with reference column 221, on permanent magnet 4, be provided with the location hole that holds reference column 221; On this reference column 221, be coaxially arranged with shaft hole 222, the two ends of shaft hole 222 are all connected with rotating shaft 1, and this rotating shaft 1 is fixedly mounted on the base of relay.This structure is convenient to the installation of permanent magnet, and is convenient to the processing of rotating shaft, guarantees that armature rotates smooth and easy.
The head of pushing block 6 is provided with push rod 61, and push rod 61 is cylindrical; On pushing block 6, be provided with a plurality of deep floors 62; Pushing block can be one-body molded on shell, also can be bolted on shell.Push rod adopts cylindrical structural, makes to adopt line contact between push rod and brace the stability while having guaranteed use.
On shell 2, be provided with balancing weight 5, the setting of balancing weight can increase the moment of inertia of armature, and the resistance when being reduced electric current and disconnected by self moment of inertia improves the reliability and stability of relay.
These are only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
