Description
Technical field
The utility model relates to technical field of electric appliances, specifically relates to high-voltage appliance switch.
background technology
High-voltage appliance switch has base, base has two strutting pieces, strutting piece is provided with contact arm, one of them is acting arm, and acting arm is hinged on strutting piece, and contact is installed in the end of contact arm, two contacts, switch connection, two contacts do not contact, and switch disconnects, during switch connection, contact can produce a large amount of heats, and these heats can be delivered on contact arm, and contact arm also plays a part to help heat radiation simultaneously; In prior art, contact arm is generally castiron, has the structure of real core, and the switch installing such contact arm has the shortcoming of radiating effect difference, also add the cost of switch in addition.
summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provide a kind of dispel the heat good, cost is low, and switch---dispel the heat good high-voltage appliance switch.
The technical solution of the utility model is achieved in that the high-voltage appliance switch that heat radiation is good, comprise base, base has two strutting pieces, strutting piece is provided with contact arm, one of them is acting arm, and acting arm is hinged on strutting piece, and contact is installed in the end of contact arm, it is characterized in that: it is alongst hollow core structures that described contact arm has, the two ends of the length direction of the through contact arm of hollow core structures.
Say further, described contact arm side has multiple through hole.
Say further, described through hole is arranged at the vertical plane of the contact arm surfaces of revolution.
Say further, described hollow core structures presents platform shape structure, and the large end of platform shape structure is in the one end of installing contact.
The beneficial effects of the utility model are: such high-voltage appliance switch has the advantage that heat radiation is good, cost is low; Described contact arm side has multiple through hole, has the better advantage of radiating effect; Described through hole is arranged at the vertical plane of the contact arm surfaces of revolution, has the less advantage affecting intensity; Described hollow core structures presents platform shape structure, has good heat dissipation effect, affects the advantage that intensity is less.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cross-sectional view in Fig. 1.
Fig. 3 is the cross section structure schematic diagram of contact arm.
Wherein: 1, one end of base 2, strutting piece 3, contact arm 4, hollow core structures 5, through hole 6, installation contact.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, 2, dispel the heat good high-voltage appliance switch, comprise base 1, base has two strutting pieces 2, strutting piece is provided with contact arm 3, one of them is acting arm, acting arm is hinged on strutting piece, contact is installed in the end of contact arm, it is characterized in that: it is alongst hollow core structures 4 that described contact arm has, the two ends of the through contact arm length direction of hollow core structures.
Say further, described contact arm side has multiple through hole 5, has the advantage that heat radiation is better like this.
Say further, described through hole is arranged at the vertical plane of the contact arm surfaces of revolution.Like this, because through hole is arranged on the vertical plane of the contact arm surfaces of revolution, and the parallel surface of the contact arm surfaces of revolution does not have, because the parallel surface of the contact arm surfaces of revolution is firmly comparatively large, so also just firmer when switch closes.
Say further, described hollow core structures presents platform shape structure, and the large end of platform shape structure is in the one end 6 of installing contact, also just firmer near hinged position like this, as shown in Figure 3.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed in the scope of the claims of the present utility model.
Claims (4)
