Abstract

The invention provides an improved structure of a connector base, comprising an insulation shell of which the front end surface and upper end surface are open, and three first to third plug holes for penetrating lead wires are formed on the back end surface of the insulation shell; first to third chambers are formed by spacer plates in the insulation shell, a horizontal spacer plate is arranged at the back part in the insulation shell to form a structure with an upper layer and a lower layer; first and second horizontal spacer plates and front and back spacer plates are also arranged respectively at the upper parts of the first and second chambers; first and second double-layer connecting terminals and spring clips are plugged into the first and second chambers of the insulation shell and positioned in the back lower layer space in the insulation shell; first and second connecting plates are penetrated into the front and back spacer plates at the upper parts of the first and second chambers, and are matched with the first and second double-layer connecting terminals to form a connecting type structure; and a single-layer connecting terminal and an spring clip are penetrated into the third chamber to form a plugging type structure. In the improved structure of a connector base, multiple connecting types are designed on one product, thus greatly reducing oversize space due to installation of more than two connectors, and the improved structure also reduces parts, cost and volume and is convenient to install.

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

Also be provided with one in the described insulation shell and supply the fixed structure of Thermal Cutoffs wire rod group plant, and establish the loam cake capping.

In addition, the present invention 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.

Beneficial effect of the present invention.

Wiring type connector, the plug wire connector device that inside and outside air-conditioning, is absolutely necessary in the machine, the present invention combines plug wire to be combined in Wiring type on the identical product, in present connector industry, belongs 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.
