Abstract
The utility model relates to a structure of a relay contact strip, and mainly solves the problems that contact points are imperfectly contacted because contact points of a relay adopt silver cadmium oxide materials, and products can not be used. The utility model provides a relay whose contact points are high temperature resistance which can not generate insulation. The technical scheme for solving the technical problems is that the relay comprises a chassis, wherein a contact foot is connected on the lower portion of the chassis, a contact piece is arranged on the chassis, the contact piece and the contact foot are connected, a retaining piece is arranged on the contact piece in the direction where the contact point is towards, a magnetic conduction system is further mounted on the chassis, the contact piece of the magnetic conduction system is arranged between the contact piece component and the retaining piece, and the contact piece, the retaining piece and the contact points of the contact piece are made of silver tin oxide indium. The relay has the advantages that the contact points are made of silver tin oxide indium, therefore, the relay can resist high temperature, can not generate insulators, reduces sales return ratio, and improves economic benefits.
Description
Technical field:
The utility model relates to a kind of relay, relates in particular to a kind of structure of relay contact chip.
Background technology:
Its work of electromagnetic relay was after energized originally, coil is with producing magnetic field between the iron core, produce certain suction on the iron core, make the spring leaf on the relay inhale moving, cause the relay output contact to move, generation is switched on or switched off state, thereby goes to control external equipment action and disconnection, reaches the control purpose.And the contact point of general relay adopts the manufacturing of Agcdo element to form, and through behind the long-play, shows to produce the blackout phenomenon, insulation occurs.Electric current can't pass through, and forms poor contact of contacts, and control signal is malfunctioning, and product can't use.China utility model patent 00213103.X discloses a kind of uninterrupted transition contacts group relay, comprises coil and contact sets, and wherein contact sets comprises moving contact, fixed contact and movable contact spring, static contact spring piece; Described static contact spring piece or movable contact spring are provided with auxiliary reed, and this auxiliary reed has the free end with respect to static contact spring piece or movable contact spring, and this free end is equipped with auxiliary contact; These auxiliary contact adopt the Agcdo manufacturing to form, and this relay just has above-mentioned shortcoming.
Summary of the invention:
The utility model has mainly solved prior art repeat circuit contact and has adopted silver cadmium oxide material to cause poor contact of contacts, and the problem that product can't use provides a kind of contact high temperature resistant, can not produce the relay of insulation.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of relay, comprise base, be connected with contact feet in the base bottom, base is provided with contact chip, contact chip is connected with contact feet, contact point on the contact chip is provided with a stop tab towards direction, the magnetic conduction system also is installed on base, the contact chip of this magnetic conduction system is arranged between contact chip assembly and the stop tab, it is characterized in that: the contact point of the contact chip of described contact chip, stop tab and magnetic conduction system all adopts the manufacturing of siller tin oxide indium to form.General contact is silver contact, silver itself is the low material of heatproof, but can not produce insulator, can keep conducting state, but silver be very expensive always, and phosphide material can be high temperature resistant, various favorable factors can not produce insulator, so after three elements were integral, all can meet the requirements, reach instructions for use on the automobile, can use for a long time.
As a kind of preferred version of such scheme, described contact chip, stop tab are static contact, and the contact chip of magnetic conduction system is a movable contact spring, and the contact point of contact chip and stop tab is provided with in opposite directions.
The utility model has the advantages that contact point adopts the manufacturing of siller tin oxide indium to form, high temperature resistant, can not produce insulator, make return of goods rate reduce, economic benefit is improved.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described.
Embodiment:
According to shown in Figure 1, the utility model comprises a base 1, the base bottom is provided with contact feet 2, base is provided with the contact chip 3 that links to each other with contact feet, contact chip is provided with contact point, contact point is provided with a stop tab 4 towards direction, the contact point of stop tab and contact chip contact point are oppositely arranged, the magnetic conduction system also is installed on base, the contact chip 5 of this magnetic conduction system is arranged between contact chip and the stop tab, and the contact point of the contact chip 5 of above-mentioned contact chip 3, stop tab 4 and magnetic conduction system all adopts the manufacturing of siller tin oxide indium to form.After adopting this made, make that contact point can be high temperature resistant, and can not produce insulator, reached the requirement of using on the automobile, can use for a long time, in like product, occupied advantage, reduced return of goods rate.
Specific embodiment described herein only is that the present invention's spirit is illustrated.The technical staff of the technical field of the invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has used terms such as contact feet, contact chip, stop tab morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; They are construed to any additional restriction all is contrary with spirit of the present invention.
