Abstract
The utility model discloses a kind of small high-power electromagnetic relays, including yoke, quiet contact group and dynamic contact group, dynamic contact group includes movable contact spring, movable contact spring is provided with dynamic spring leading foot, the at least a piece of dynamic spring auxiliary leading foot with dynamic spring leading foot side by side is wholely set on movable contact spring, dynamic spring auxiliary leading foot mutually amplexiforms the dynamic contact group leading foot of composition with dynamic spring leading foot after folding, advantage is to replace product yoke foot by the way that product reed is carried out multilayer folding, directly carry out foot extraction, in the case where guaranteeing reed cross-sectional area, product loaded line reduces bridge joint, reed and leading foot one, since the on-state rate and heat dissipation performance of copper foot are better than iron foot, improve the stability of relay load path, it further reduced product temperature rise.
Description
Technical field
The utility model relates to a kind of relays, more particularly, to a kind of small high-power electromagnetic relay.
Background technique
Relay is a kind of using extensive electronic component, no matter the operating principle of relay, how is structure type
Multifarious, they are all by receiving input signal (induction mechanism), comparing mechanism and executing agency (output circuit) three parts
Composition, electromagnetic relay receive input signal and are usually inputted by coil leading foot input current, and output circuit is usually by dynamic contact
Group leading foot and it is quiet connect a group leading foot and be communicated with the outside connect.
As shown in Figure 1, original relay loaded line is to be welded or be riveted on yoke by reed, then by yoke
Leading foot is as dynamic contact group leading foot, and route needs to bridge in this case；With the development of the complete machine of relay, usually want
It asks relay small in size and loads greatly, and temperature rise caused by relay inner heat will affect the longevity of relay after load increase
Life, and the on-state rate and thermal diffusivity of the iron foot of the prior art are then relatively weaker.
No. 201720834263.1 Chinese utility model patents of open authorization on February 13rd, 2018 disclose a kind of small
Type high-power magnetic relay, including magnetic circuit system and contact system, magnetic circuit system include yoke, and contact system includes quiet contact
Group and dynamic contact group, moving contact group includes movable contact spring, and feature is that yoke is provided with yoke leading foot, and movable contact spring is provided with dynamic spring and draws
Foot out, yoke leading foot mutually amplexiform the dynamic contact group leading foot of composition with dynamic spring leading foot；Advantage is that the temperature rise of the relay is small, body
Product is small, the service life of relay when can ensure heavy load.
But user has wanted to a kind of on-state rate and the better structure of heat dissipation performance.
Summary of the invention
It is more preferable than the prior art that the technical problem to be solved by the utility model is to provide a kind of on-state rates and heat dissipation performance
Small high-power electromagnetic relay.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of small-sized high-power electromagnetism relay
Device, including yoke, quiet contact group and dynamic contact group, the dynamic contact group includes movable contact spring, and the movable contact spring is provided with dynamic
Spring leading foot is wholely set on the movable contact spring and at least a piece of draws with the dynamic spring auxiliary of the dynamic spring leading foot side by side
Foot, the dynamic spring auxiliary leading foot mutually amplexiform the dynamic contact group leading foot of composition with the dynamic spring leading foot after folding.
The dynamic spring auxiliary leading foot can be two panels.
The dynamic spring auxiliary leading foot rear end adjacent with the dynamic spring leading foot passes through rivet and the dynamic spring
Leading foot is fixed on together on the yoke.
Compared with prior art, the utility model has the advantage of replace product by the way that product reed is carried out multilayer folding
Yoke foot, directly progress foot extraction, in the case where guaranteeing reed cross-sectional area, product loaded line reduce bridge joint, reed and
Leading foot one, since the on-state rate and heat dissipation performance of copper foot are better than iron foot, improves the stability of relay load path,
It further reduced product temperature rise.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the prior art；
Fig. 2 is the schematic perspective view of the utility model；
Fig. 3 is the structural schematic diagram of the movable contact spring blank of the utility model embodiment；
Fig. 4 is the schematic perspective view that movable contact spring blank shown in Fig. 3 carries out multiple folding；
Fig. 5 shows to form the stereochemical structure of dynamic contact group leading foot after movable contact spring blank shown in Fig. 3 progress multiple folding
It is intended to.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
Embodiment: as shown in Figure 2-5, a kind of small high-power electromagnetic relay, including yoke 1, quiet contact group 2 and dynamic
Contact group 3, moving contact group 3 includes movable contact spring 31, and movable contact spring 31 is provided with dynamic spring leading foot 32, has been wholely set on movable contact spring 31
The dynamic spring of two panels and dynamic spring leading foot 32 side by side assists leading foot 33, move after spring auxiliary leading foot 33 folds with dynamic spring leading foot 32
Mutually amplexiform the dynamic contact group leading foot of composition, dynamic spring auxiliary leading foot 33 rear end adjacent with dynamic spring leading foot 32 by rivet 4 with
Dynamic spring leading foot 32 is fixed on together on yoke 1.
The dynamic spring auxiliary leading foot 33 of the utility model can be multi-disc.
