Abstract
The utility model discloses an insulation contact arm used for a switch cabinet. The insulation contact arm comprises a conducting rod. An insulation sleeve is sleeved out of the conducting rod. Two ends of the insulation sleeve are provided with a first terminal and a second terminal respectively. The first terminal is directly connected to one end of the conducting rod. The second terminal is connected to the other end of the conducting rod through a spring. A heat dissipation tube is sleeved out of the insulation sleeve. Several annular heat dissipation fins are distributed on an outer wall of the heat dissipation tube with equal intervals. The structure of the contact arm of the utility model is simple and reasonable. Installation and usage are convenient. A design that the heat dissipation tube is arranged out of the insulation contact arm is used so that heat dissipation performance of the insulation contact arm is effectively increased. High heat emitted by the conducting rod can be rapidly and high-efficiently absorbed. An aging phenomenon of an insulation part is alleviated and a service life is prolonged. Conductive stability and usage safety of the insulation contact arm are guaranteed.
Description
Technical field
The utility model relates to a kind of electric fittings, is specially insulation contact arm for a kind of switch cubicle.
Background technology
Insulation contact arm is electric fittings conventional in switch cubicle, and existing insulation contact arm structure is reasonable not, it is convenient not to install and use, heat dispersion is poor, after long-time use, outer layer insulation parts are easily subject to the temperatures involved of conducting rod and aging phenomenon occur, and then the conductive stability of the contact arm that makes to insulate declines, and insulation property can not get ensureing, shorten useful life, has potential safety hazard.
Utility model content
The purpose of this utility model is to provide insulation contact arm for a kind of switch cubicle, reasonable not to solve insulation contact arm structure traditional in prior art, it is convenient not to install and use, heat dispersion is poor, after long-time use, outer layer insulation parts are easily subject to the temperatures involved of conducting rod and aging phenomenon occur, and then the conductive stability of the contact arm that makes to insulate declines, and insulation property can not get ensureing, shorten useful life, has the problem of potential safety hazard.
For achieving the above object, the technical solution adopted in the utility model is:
Insulation contact arm for a kind of switch cubicle, it is characterized in that: include conducting rod, described conducting rod overcoat has insulating case, described insulating case two ends are separately installed with the first binding post and the second binding post, described the first binding post is directly connected to conducting rod one end, described the second binding post is connected to the conducting rod other end by spring, and described insulating case overcoat has radiating tube, and described radiating tube outer wall equal intervals is distributed with some circular radiating fins.
Insulation contact arm for described a kind of switch cubicle, is characterized in that: described radiating tube two ends are provided with the installation card base matching with insulating case.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, easy to install, employing arranges the design of radiating tube outward at insulation contact arm, effectively improved the heat dispersion of insulation contact arm, the high heat can absorption conducting rod rapidly and efficiently sending, the aging phenomenon that slows down insulating element, has extended useful life, has guaranteed the conductive stability of insulation contact arm and has used safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
