Abstract

A high power relay comprises an outer cover (10), a bed plate (2), a yoke (8), a keeper (6), an iron core (7), a coil (3), a confluence plate (17), a moving contact (5), a reed (15), etc. the utility model mainly improves a current channel and the positioning structure of the keeper as well as the reed structure. The current channel includes the two output ways of the moving contact (5), the confluence plate (17) and a terminal (1) and the moving contact (5), the reed (15), a keeper (6) and the confluence plate (17). The overloading capacity of the relay is greatly enhanced. Simultaneously, a positioning rod (17) is additionally added on the yoke (8), which effectively positions the action range of the keeper (6) and leads to the more reliable performance and more stable products. In addition, the structure of the reed (15) is improved to be equipped with a folded angle, which increases the contact pressure of the contact and supplies the reed with film cleaning, vibration resistance and melting and welding resistance properties.

Description

A kind of high power relay

Technical field

The utility model relates to a kind of high power relay, particularly relate to a kind of reliability height, overload capability strong be mainly used in clapper-type high-power magnetic relay in large-scale truck, motorcycle and the high-power start equipment.

Background technology

Existing relay electromagnet has clapper-type and helix tube type, it has been generally acknowledged that beating type electromagnet can not drive excessive load, has only screwed pipe double-contact formula can realize the carrying of heavy load.The utility model is optimized the load current passage of electromagnetic relay, a kind of new construction that the evacuation heating has proposed beating type electromagnet by new construction, and load capacity is strong, and the suction-combining force is big, and contact force is big, and in stable condition reliable, anti-vibration and impact capacity are strong.

Summary of the invention

1. the technical problem that will solve

The purpose of this utility model is exactly to improve the load capacity and the contact contact pressure of clapper-type electromagnetic relay, limits the actuating range of armature simultaneously, makes more reliable performance, and product is more stable.

2. technical scheme

For reaching above-mentioned target, the utility model has adopted new current channel and limiting position of armature structure, and for increasing the contact contact pressure, reed structure is improved.New current channel is: the one tunnel through being welded to soft on line 14 direct the importings on conflux sheet, the binding post 11 on the movable contact, one the tunnel imports on the sheet that confluxes, the binding post 11 through movable contact, reed-armature, soft on line 16, final two-way closes in together, has greatly strengthened the overload capacity of relay.As shown in Figure 1 and Figure 2.

Simultaneously, will increase gag lever post on the iron yoke, form globality gag lever post iron yoke, adjust its gag lever post to spacing point, limit the actuating range of armature effectively, make Product Status reliable and stable in product assembling back.As shown in Figure 2

In addition, in the improvement of reed structure, increased the bending angle, not only strengthened the contact pressure of contact, also made it have the ability of film, antivibration and anti-melting welding clearly.As shown in Figure 3

3. beneficial effect

Beneficial effect of the present invention is exactly to have designed a kind of high-power magnetic relay novel, that overload capability is strong, makes it in large-scale truck, motorcycle and high-power start equipment, has played starting and control action.Realized the application of relay in powerful device.

Fig. 2 is the vertical view after high power relay cuts open outer cover, also is simultaneously that gag lever post iron yoke limits armature movement scope schematic diagram;

Fig. 3 is the schematic diagram of band bending angle reed.

Among the figure: 1,11 binding posts, 2 seat boards, 3 coils, 4 breaks, 5 movable contacts, 6 armature, 7 iron cores,

8 iron yokes, 9 springs, 10 outer covers, 12 lug plates, 13 insulating sleeves, 14,16 soft on lines,

15 reeds, 17 sheets that conflux, 18 gag lever post iron yokes.

Embodiment

As shown in Figure 1 and Figure 2, the utility model high-power magnetic relay comprises electromagnet system and contact system; Electromagnet system makes relay finish closure by exciting current or disconnects action.Electromagnet system comprises: iron core 7, coil 3, iron yoke 8, armature 6, and they have constituted the magnetic circuit of coil and magnet; Contact system comprises that two-way connects soft on

line

14,16, insulating sleeve 13, big sphere major diameter movable contact 5, fixed contact 4, reed 15, the sheet 17 that confluxes, spring 9, binding

post

1,11 etc.All the other are seat board 2 and the outer cover 10 of fixing these electromagnetic systems and contact system.When relay is in off-state, the coil both end voltage that raises gradually, relay is converted to attracting state by off-state; After the relay adhesive, reduce the coil both end voltage gradually, relay is converted to off-state by attracting state, realizes its conversion and control effect.

In Fig. 1, Fig. 2, soft on

line

14,16 is selected the special soft whipping wire material of the copper of high conduction for use, and at insulating sleeve 13 of soft on line 14 overcoats; One tunnel soft on line 14 directly is welded on the movable contact 5, and the soft on line 16 in another road is welded on the armature 6, and final two-way is with being welded on the sheet 17 that confluxes; When relay is worked, one part of current flows to binding post 11 by movable contact 5 through soft on line 14, the sheet 17 that confluxes, another part electric current flows to binding post 11 by movable contact 5, reed 15, armature 6, soft on line 16, the sheet 17 that confluxes, and with the input load shunting, gathers output at last again; Disperse heating, increased overload capacity.

In Fig. 2, gag lever post iron yoke 18 defines the actuating range of armature 6 effectively after adjusting, and has stopped armature 6 effectively by the possibility of ejection iron yoke, has greatly improved reliability of products, stability.

In Fig. 3, reed has increased the bending angle [alpha], and the increase of this angle has further strengthened dynamic and static contact and pressed power indirectly, has guaranteed that contact resistance is little and stable, and the ability of film, antivibration and anti-melting welding is clearly arranged.When the carrying heavy load, guaranteed the reliable connection of product.
