Abstract
The utility model discloses a radiating electric contact bridge, which comprises a copper substrate (1) and a noble metal layer (2) and is characterized in that one surface of the copper substrate is provided with a plurality of radiating reinforcement ribs (3), the height of each radiating reinforcement rib is 30-50% the thickness of the copper substrate, the radiating reinforcement ribs are 15-20mm long and 2-4mm wide, and the space between every two radiating ribs is 8-12mm. As one surface of the copper substrate is additionally provided with the radiating reinforcement ribs, the purpose of heat radiating is achieved on one hand, and on the other hand, the resistance of deformation of the contact bridge due to temperature rise is greatly increased, thereby prolonging the service life of products.
Description
Technical field
The utility model relates to a kind of electric contacts, relates in particular to a kind of heat radiating type and electrically contacts bridge.
Background technology
As everyone knows, in the course of the work, by electrical contact material be connected with the copper pedestal and the contact assembly that forms and configuration cooling fan device in electrical equipment, mainly undertake the effect of break-make power supply and protection appliance circuit.Because large electric current produces high temperature during by contact bridge moment, heat can't in time shed, and causes that the contact bridge matrix burns out, matrix distortion, layer of precious metal come off etc.When contact assembly enters normally closed on-state, by its heavy current, because the impact of contact resistance or loose contact factor can make contact material and copper pedestal produce the situation of heating up equally.The sets of contacts component that contact is connected with the supporting structure of conduction in original electrical equipment, with by increasing volume or assembling radiating element, cooling fan mode, carry out natural heat dissipation, forced heat radiation, thereby increase noble metal dosage and numerous and diverse structure, also can easily break down.
The utility model content
The purpose of this utility model be to provide in order to overcome the deficiencies in the prior art a kind of can efficiently radiates heat, reduce the distortion of copper pedestal, the heat radiating type that prolongs contact bridge useful life electrically contacts bridge.Its concrete technical scheme is: heat radiating type electrically contacts bridge and comprises the copper matrix, layer of precious metal, and a surface of copper matrix is provided with several heat radiation reinforcements.
Said heat radiation reinforcement, it highly is 30%-50% of copper matrix thickness, and length is 15-20mm, and width is 2-4 mm, and distance is 8-12mm between the heat radiation reinforcement.
Can find out from the technical solution of the utility model, owing to having set up several heat radiation reinforcements on a surface of copper matrix, reached on the one hand the purpose of heat radiation, greatly increased again on the other hand contact bridge because the resistance of temperature rise distortion, thereby prolonged the useful life of product, reached goal of the invention of the present utility model fully.
Description of drawings
Fig. 1 is the structural representation that the utility model heat radiating type electrically contacts bridge.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1, and heat radiating type electrically contacts bridge and comprises copper matrix 1, layer of precious metal 2, and a surface of copper matrix is provided with several heat radiation reinforcements 3.Said heat radiation reinforcement, it highly is 30%-50% of copper matrix thickness, and length is 15-20mm, and width is 2-4 mm, and distance is 8-12mm between the heat radiation reinforcement.
Claims (2)
