Abstract

The utility model, which discloses a kind of relay contact structure, includes contact, and the surface of the contact forms groove, and the top edge of the groove is highlightedly provided with some electrically conducting contacts；When the contact is with another contact, the electrically conducting contact makes electrical contact with another contact.The utility model relay contact structure has conductive effect good, can reduce the advantage of heating.

Description

Relay contact structure

Technical field

The utility model is related to a kind of relay, more particularly to a kind of relay contact structure.

Background technology

Relay is a kind of electronic control device, and it has control system and by control system, is commonly used to automatic control In circuit processed, it is actually a kind of automatic switch for removing to control larger electric current with less electric current, therefore is played in circuit Automatically adjust, safeguard protection, the effect such as change-over circuit.

Existing relay, the export structure of its high current is general by setting a conducting block, sets dynamic on conducting block Terminal, then moved by coil suction band moving conductive block, and then moved end is driven close to the static terminal of relay, so that moved end Contact electrical contact on contact and static terminal on son, final high current enters from input, and passes through the contact of static terminal, moves Exported behind the contact of terminal and conducting block from output end.

However, above-mentioned structure can generate heat larger when by high current, its reason is：Moved end son on contact with it is quiet Although contact on terminal is face-to-face combination in contact, still, because the surface of contact there may be out-of-flatness, therefore, In contact, it is most likely that can occur the phenomenon of the wherein peak of a contact and another contact so that only have two contacts Single-contact, therefore the resistance in contact position is very big, when being passed through high current, heating will be very big, so that relay Internal accumulated heat is serious, and conductive effect is poor, has influence on the service life of relay.

Utility model content

The purpose of this utility model is to provide that a kind of conductive effect is good, reduces the relay contact structure of heating.

To achieve these goals, the relay contact structure that the utility model is provided includes contact, the table of the contact Face forms groove, and the top edge of the groove is highlightedly provided with some electrically conducting contacts；When the contact is with another contact, The electrically conducting contact makes electrical contact with another contact.

Because the utility model is by the surface setting groove in the contact, and make the top edge of the groove highlightedly Provided with electrically conducting contact, so that when the contact makes electrical contact with other contacts, carrying out multiple spot conduction by electrically conducting contact, keeping away Exempting from traditional only one of which contact conductive causes conductive resistance to increase, the elevated shortcoming of caloric value, makes the obvious reduction of relay heating, Increase the service life.

It is preferred that the contact is in integrated formed structure with the electrically conducting contact.

It is preferred that the groove is rectangle, linear edge arrangement of the electrically conducting contact along the groove.

It is preferred that the material of the contact and the electrically conducting contact is copper, gold or silver.

It is preferred that the electrically conducting contact is conducting treadle bar or conductiving point.

Embodiment

To describe technology contents of the present utility model, construction feature, the effect realized in detail, below in conjunction with embodiment And coordinate accompanying drawing to be explained in detail.

As shown in Figure 1 and Figure 2, the utility model relay contact structure 100 include contact 1, the contact 1 be fixed on after On the static terminal 201 of electrical equipment, the surface of the contact 1 forms groove 11, if the top edge 11a of the groove 11 is highlightedly provided with Dry electrically conducting contact, the electrically conducting contact is conducting treadle bar or conductiving point 12.The electrically conducting contact of the present embodiment is used The form of multiple conductiving points 12, the contact 1 is in integrated formed structure with the conductiving point 12.The contact 1 and the conduction The material of point 12 is copper, gold or silver-colored.The groove 11 is rectangle, linear edge row of the conductiving point 12 along the groove 11 Row.

Because the utility model is by the surface setting groove 11 in the contact 1, and make the top edge of the groove 11 11a is highlightedly provided with multiple conductiving points 12, when the static terminal 201 in relay 200 and moved end 202 are close to each other and described tactile When point 1 and the plane of the contact 203 on moved end 202 make electrical contact with, carry out contacting conductive by multiple conductiving points 12, the present invention is extremely The contact 203 of rare 3-4 conductiving point and moved end 202 makes electrical contact with, so as to avoid traditional only one of which contact conductive from causing Conductive resistance increases, the elevated shortcoming of caloric value, makes the obvious reduction of relay heating, increases the service life.

Above disclosed is only preferred embodiments of the present utility model, can not limit the utility model with this certainly Interest field, therefore equivalent variations made according to present utility model application the scope of the claims still fall within the utility model and are covered Scope.
