Problems solved by technology
[0008] In the above several schemes, for the user, the busbar for connection and the radiator for heat dissipation are two separate parts, and the user needs to purchase the busbar and radiator separately and assemble them. Poor
In addition, for switch manufacturers or connecting busbar manufacturers, because the busbar usually adopts U-shaped structure and is obtained by punching process, it is inevitable that it is difficult to maximize the material utilization, especially for precious metals. Better material utilization solutions are often required
Therefore, in the manufacture of busbars, the material utilization rate will be considered as the first choice, so the connection between busbars and radiators and the effect of heat dissipation will be affected.
Moreover, the production of radiators needs to open a special mold, and the cost of the mold is also a cost burden for the manufacturer

Embodiment Construction
[0025] The invention discloses a switch connector. The connector itself conducts electricity, so it has the function of carrying current. At the same time, at least a part of the connector forms a heat dissipation area with a gap, and the heat dissipation area performs the function of heat dissipation.
[0026] In one embodiment, the connector is formed by overlapping several connecting pieces, the connector forming the first part and the second part. In the first part, several connecting pieces are in contact with each other and have connection means to the switch on the first part, which acts as a busbar. In the second part, gaps are formed between several connecting pieces, and the second part functions as a heat sink.

The invention discloses a connector of a switch. The connector is a conductive connection. At least one portion on the connector forms a heat-dissipating area with gaps. In one embodiment, the connector is formed by overlapping a plurality of connecting pieces. The connector forms a first portion and a second portion. In the first portion, the connecting pieces are contacted with each other, and a connecting mechanism which is connected with the switch is formed on the first portion. In the second portion, gaps are formed among the connecting pieces. The first portion is used as a busbar, and the second portion is used as a heat sink. The connector of the switch of the invention simultaneously has current-carrying and heat-dissipating functions, and integrates the bus-bar and the heat sink together. The connector of the switch of the invention is simple in structure, excellent in performance, convenient for installing, and low in implementation cost.
Description
technical field [0001] The present invention relates to the field of low-voltage electrical appliances, and more particularly, to a connector for a switch. Background technique [0002] In a DC system with high working voltage (such as DC1000V or DC1500V), it is necessary to connect multiple breakpoints of multi-pole switches in series to meet performance requirements (such as short circuit, isolation, etc.). Usually users will use cables to connect multi-pole switches in series. In order to avoid excessive operating temperature, long cables are often required. [0003] In the prior art, there are special connectors for series connection provided by some switch manufacturers, which facilitates the on-site wiring of users. More solutions are to set the disconnecting unit of the switch outside the switch, and some switch manufacturers directly install the switch The disconnect unit is connected inside the switch, eliminating the need for user wiring in the field. However, no...
