Further, the utility model also comprises a clinching, and the clinching bottom is offered some to lead, first bilayer, second bilayer, the spacing fixed groove of individual layer binding post; The horizontal baffle rear portion at rear portion has the slotted eye that passes for this clinching in the described insulation shell, and rear portion lower layer space in the insulation shell, fixed groove corresponding lead, first bilayer, second bilayer, individual layer binding post are inserted in the clinching bottom.

One fixed structure for the plant of Thermal Cutoffs wire rod group also is set in the described insulation shell, and establishes the loam cake capping.

In addition, the utility model also comprises Thermal Cutoffs wire rod group and Thermal Cutoffs, and pedestal is established in Thermal Cutoffs wire rod group outer end; Described Thermal Cutoffs wire rod group and Thermal Cutoffs are positioned over sheaf space on the insulation shell rear portion, and are fixed by plurality of fixed post and loam cake.

The beneficial effects of the utility model.

Wiring type connector, the plug wire connector device that is absolutely necessary in the machine inside and outside air-conditioning, the utility model combines plug wire and is combined on the identical product with Wiring type, in present connector industry, belong to initiative.The design of multiple connected mode on identical product, is dwindled greatly and two above connectors are installed and are caused the space excessive; And, reduce part, reduce cost, reduced volume is installed portable.
