Description
Technical field
It the utility model is related to a kind of relay, more particularly to a kind of conductive structure of relay.
Background technology
Existing DC relay, its operation principle is to produce magnetic field by being powered to coil, using magnetic field pull-core,
Iron core is set to drive movable seat movement, and movable seat then drives travelling contact platform to be contradicted with face terminals, so that two face terminals
Connect, realize the conducting of high current.
However, during travelling contact platform and face terminals electrical contact, since travelling contact platform connects with face terminals
Tactile contact surface can not make absolute plane, therefore both are actually point contact, when electric current is by this contact point,
Resistance becomes very big, so that substantial amounts of heat is produced, and these heats are difficult to quickly disperse inside relay so that and relay
Internal temperature is higher and higher, finally seriously affects the service life of relay.
Utility model content
The purpose of this utility model is to provide a kind of electric conductivity is excellent, the effective service life for extending relay is led
Electric structure.
To achieve these goals, the conductive structure of relay provided by the utility model includes travelling contact platform and load
Terminal, the travelling contact platform are actively arranged in the movable seat of relay, and the face terminals are fixed on the relay
Interior, the travelling contact platform includes conductive bodies, and the first side of the conductive bodies is equipped with least two and the face terminals
The contact site of electrical contact, the surface of the contact site are equipped with the conductive layer made of silver or silver alloy.
Compared with prior art, the utility model connects by setting contact site on the travelling contact platform, and described
The surface of contact portion is equipped with the conductive layer made of silver or silver alloy, since the silver or silver alloy have excellent electric conductivity,
Resistance is minimum so that electric current is minimum by caloric value during travelling contact platform so that avoid because high temperature influence relay inside other
The performance of element, therefore, effectively extends the service life of relay, improves the performance of relay.
It is preferred that the middle part of the first side of the conductive bodies is equipped with boss.
Specifically, the middle part of the second side of the conductive bodies opposite with first side is equipped with depression.
It is preferred that the contact site is in truncated cone-shaped or square structure.
It is preferred that the first side of the conductive bodies is equipped with arc raised line corresponding with the contact site, and the arc
Raised line and the contact site are concentric.
Brief description of the drawings
Fig. 1 is the structure diagram of the conductive structure of the utility model relay.
Fig. 2 be the utility model relay conductive structure in travelling contact platform structure chart.
Fig. 3 is the schematic diagram of another structure of the conductive structure of the utility model relay.
Embodiment
To describe the technology contents of the utility model, construction feature, the effect realized in detail, below in conjunction with embodiment
And attached drawing is coordinated to be explained in detail.
As shown in Figures 1 and 2, the conductive structure 100 of the utility model relay includes travelling contact platform 1 and face terminals
2, the travelling contact platform 1 is actively arranged in the movable seat of relay, and the face terminals 2 are fixed on the relay
Interior, the travelling contact platform 1 includes conductive bodies 11, the both ends of the first side of the conductive bodies 11 be highlightedly equipped with two with
The contact site 12 that the face terminals 2 make electrical contact with, the surface of the contact site 12 are equipped with the conductive layer made of silver or silver alloy
13。
The middle part of first side of the conductive bodies 11 is equipped with boss 11a.Opposite with first side is described conductive main
The middle part of second side of body 11 is equipped with depression 11b, the depression 11b and is used for the spacing rib of accommodating movable seat.
The contact site 12 is in truncated cone-shaped or square structure.
First side of the conductive bodies 11 is equipped with arc raised line 11c corresponding with the contact site 12, and the arc
Raised line 11c and the contact site are concentric.
Compared with prior art, the utility model on the travelling contact platform 1 by setting contact site 12, and described
The surface of contact site 12 is equipped with the conductive layer 13 made of silver or silver alloy, since the silver or silver alloy have excellent conduction
Performance, resistance are minimum so that electric current is minimum by caloric value during travelling contact platform 1, so as to avoid because high temperature is influenced in relay
The performance of portion's other elements, therefore, effectively extends the service life of relay, improves the performance of relay.
As shown in figure 3, illustrate another structure of the conductive structure of the utility model relay in figure, its structure with it is upper
It is essentially identical to state the conductive structure 100 of embodiment relay, difference is the travelling contact platform 1 ', is led described in the present embodiment
The middle part of first side of electric main body 11 ' does not have boss, and the middle part of the first side is planar structure 11a ', opposite with first side
The middle part of second side of the conductive bodies 11 ' is not also recessed, and the middle part of the second side is also planar structure 11b '.The present embodiment
Beneficial effect and upper embodiment it is essentially identical, be not repeated herein.
Above disclosed is only the preferred embodiments of the utility model, cannot 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.
