Abstract
The utility model discloses a silver contact for a relay, aims to provide a silver contact which meets requirements for low carbon, high efficiency and sustainable development of industrial products in the current society. An abutted part is connected in a detachable manner with one end, opposite to a riveting part, of a contact part; a plurality of connection rods are disposed on one end face, faced to the contact part, of the abutted part; the contact part is provided with a plurality of mounting holes which are in inserted and detachable connection with the connection rods; and the abutted part is made from a silver material while the contact part and the riveting part is made from a copper material. A non-abutted working part of a contact body is made from the copper material instead of the silver material, such that a large amount of silver material is effectively saved while guaranteeing the characteristics of high conductivity, low resistance value, excellent contact and high-efficiency electric conduction of a conventional whole-silver contact, thereby meeting the general requirements for low carbon, low price, conservation and simplicity of the modern society.
Description
Technical field
The utility model relates to a kind of silver contact, and more particularly, it relates to a kind of relay silver contact.
Background technology
Relay is a kind of in circuit, according to designing requirement, is frequently switched on or switched off selectively the components and parts of circuit, in electrical apparatus industry, is widely used, and the moment can not be rare or scarce.
Contact is the key component that relay is switched on or switched off circuit, has dividing of one side contact and two-sided contact.Contact in the past, in order to meet high conductivity, low-resistance value, the requirement of good contact and high-effective conductive, is mostly all used silver-colored material to make.
The relay contact that uses silver-colored material to make, although there is high conductivity, low-resistance value, good contact, high-effective conductive and the feature that is not easy to cause electric spark, but because silver-colored material belongs to rare, noble metal, all exist both at home and abroad yield low, the problem that use amount is large, therefore, relay has with full silver contact that silver consuming amount is large, high cost shortcoming, can not meet modern society's low-carbon (LC), at a low price, saving, brief general requirement.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of relay silver contact, this kind of silver contact meet society now to industrial products low-carbon (LC), efficiently, the demand of sustainable development.
For achieving the above object, the utility model provides following technical scheme: a kind of relay silver contact, comprise contact bodies, described contact bodies comprises contact site and is convexly set in the caulking part of contact site one end, described contact site is removably connected with contact part with respect to the other end of caulking part, described contact part convexes with some connecting rods with respect to an end face of contact site, described contact site is provided with some installing holes, described installing hole and connecting rod are detachably pegged graft, described contact part is made by ag material, and described contact site and caulking part are made by copper product.
Described connecting rod slightly favours the central axis of contact part.
Described contact part side is provided with for wrapping the sticking part of contact site sidewall.
A kind of relay silver contact, comprise contact bodies, described contact bodies comprises contact site and is convexly set in the caulking part of contact site one end, described contact site is removably connected with contact part with respect to the other end of caulking part, described contact part convexes with some connecting rods with respect to an end face of contact site, and described contact site is provided with some installing holes, and described installing hole and connecting rod are detachably pegged graft, described contact part is made by ag material, and described contact site and caulking part are made by copper product.By adopting technique scheme, non-conflict working portion in contact bodies is replaced to ag material with copper product, make it possess former full silver contact high conductivity, low-resistance value, in the time of good contact and high-effective conductive feature, mass efficient ground saving silver material, with meet modern society's low-carbon (LC), at a low price, saving, brief general requirement.
Accompanying drawing explanation
Fig. 1 is the structural representation of silver contact for the utility model relay.
Reference numeral: 1, contact bodies; 11, contact site; 12, caulking part; 13, contact part; 111, installing hole; 131, connecting rod; 132, sticking part.
Embodiment
With reference to Fig. 1, the utility model relay is described further with silver contact embodiment.
A kind of relay silver contact, comprise contact bodies 1, described contact bodies 1 comprises contact site 11 and is convexly set in the caulking part 12 of contact site 11 one end, described contact site 11 is removably connected with contact part 13 with respect to the other end of caulking part 12, described contact part 13 convexes with some connecting rods 131 with respect to an end face of contact site 11, described contact site 11 is provided with some installing holes 111, described installing hole 111 is detachably pegged graft with connecting rod 131, described contact part 13 is made by ag material, and described contact site 11 and caulking part 12 are made by copper product.Non-conflict working portion in contact bodies 1 is replaced to ag material with copper product, because copper is in movable metallic sequence table, ranking is only low one than silver, conductance is basic identical, make contact possess former full silver contact high conductivity, low-resistance value, in the time of good contact and high-effective conductive feature, mass efficient ground saving silver material, with meet modern society's low-carbon (LC), at a low price, saving, brief general requirement.The connecting rod 131 of contact part 13 is pegged graft and is realized being fixedly connected with of contact part 13 and contact site 11 into installing hole 111, this structure not only can improve the axiality of contact part 13 while being connected with contact site 11, and this structure also can realize contact part 13 and separate with contact site 11, convenient by 13 recyclings of silver contact part, avoid causing unnecessary waste.
Described connecting rod 131 slightly favours the central axis of contact part 13.Because silver-colored quality is than general metallic flexible, therefore when the connecting rod 131 slightly tilting can produce distortion when inserting installing hole 111, and be inserted in installing hole 111, connecting rod 131 and installing hole 111 are fitted tightly, promoted the stable connection of contact part 13 with contact site 11.
Described contact part 13 sides are provided with for wrapping the sticking part 132 of contact site 11 sidewalls.Sticking part 132 can increase the fitting area of contact part 13 and contact site 11, strengthens its electric conductivity, and avoids because of contact site 11 made of copper easy electric spark causing when near contact.
