Description
Technical field
The utility model belongs to technical field of electricity, relates to single-phase magnetic latching relay.
Background technology
It is big that existing single-phase magnetic is protected the magnetic relay volume, and the common relay two-terminal form of drawing is plane formula (promptly drawing along X, Y direction), the bringing-out minor structure is single to lack variation, and with overall structure is loose especially after instrument transformer is connected, it is bigger to take up room.
The utility model content
The purpose of this utility model is to provide a kind of instrument transformer integrated single-phase magnetic latching relay, and its volume is little, simple and compact for structure, can the magnetic disturbance of anti-external magnetic field.
For reaching above purpose, solution of the present utility model is:
A kind of single-phase magnetic latching relay, it is into a single integrated structure that its exit at relay connects instrument transformer by annex, makes that the relay overall volume is little, compact conformation.
The exit of this relay adopts three dimensional form to draw, and increases the optional form of leading-out terminal.
This annex comprises annealed copper wire, copper tip, wears annealed copper wire in the middle of the instrument transformer and is connected with copper tip, and copper tip is connected with the exit of relay.
This connected mode is welding.
The outside magnetic circuit system of this relay is arranged with metallic shield, and radome also is provided with insulating shield outward, prevents the magnetic disturbance of external magnetic field to relay.
Also comprise packing ring in the moving contact assembly of this relay, the packing ring pad is played a supporting role on shell fragment, helps increasing the contact and opens distance.
Owing to adopted above technical scheme, the utlity model has following beneficial effect: relay instrument transformer overall volume of the present utility model is little, and compact conformation is easy for installation; Metallic shield can prevent the magnetic disturbance of external magnetic field to relay, improves safe and reliable property; The contact system structure can increase the contact and open distance, the electric arcing that causes when reducing relay work, thereby its useful life that prolongs; Magnetic circuit system simple in structure has guaranteed the confining force of product, has reduced the technology difficulty in the processing again, and assembling easily.

Embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is further described.
The utility model mainly is to utilize the two-terminal form of drawing to be three-dimension type (promptly drawing along X, Z axle or Y, Z-direction), thus bigger saving the space on plane, overall volume is diminished.
As shown in Figure 1, relay 1 outside magnetic circuit system 9 positions are with metallic shield 2, radome 2 adds an insulating shield 3, and be connected instrument transformer 4 in aggregates with it at the exit one side employing annex of relay 1, annex is common annealed copper wire, copper tip, wear the welding of annealed copper wire and copper tip in the middle of the instrument transformer 4, copper tip forms whole the connection with the exit welding of relay 1 again.As shown in Figure 2, relay 1 inside is provided with corresponding fixed contact assembly 5, moving contact assembly 6, compression spring 7, push card 8 and magnetic circuit system 9.Wherein the part of the moving plate in the moving contact assembly 6 is made up of packing ring 11, shell fragment 12, large shunt sheet 13, little splitter 14, movable contact spring 15 and moving contact 16, as shown in Figure 3, straight chip shell fragment 12 direct rivetings are in contact tail in the moving contact assembly 6 in the contact system, and being lined with a packing ring 11, the direction of shell fragment 12 can be adjusted according to actual needs; When packing ring 11 disconnects in the contact, can play a supporting role at shell fragment 12 backs, reduce the shell fragment deflection, increase the effect that distance is opened in the contact thereby play, also increased area of dissipation, packing ring 11 can be processed into different shapes according to the structure needs, as common circle, ellipse, square, triangle, polygon etc.; Magnetic circuit system 9 is made up of U type armature 17, coil 18, armature component 19 and clamping plate 20, and as shown in Figure 4, whole magnetic circuit system is simple in structure, and processing technology is good, is convenient to assembling.The utility model magnetic circuit principle is with in the past magnetic circuit system, and coil is not need long-time energising, only needs a pulse signal just can make the actuating of relay, and change coil stimulating current polarity just can be controlled the disconnection and the closure of contact sets.
More than describing is can understand and use the utility model for ease of the those of ordinary skill in this field.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the utility model is not limited to the foregoing description, and those skilled in the art should be within protection range of the present utility model for improvement and modification that the utility model is made according to announcement of the present utility model.
