Abstract
The utility model discloses an upside-down mounted insulating strip which comprises a body, two leads and a safety buckle. The body is provided with a penetrating central hole, and two sides of the central hole are equipped with two penetrating contact position clip holes that are communicated with the central hole. Any of the two leads has a contact end riveted with a contact and a free end opposite to the contact end. The contact ends of the two leads respectively penetrate out of the central hole from the back side of the body and are laterally moved to the two contact position clip holes. The safety buckle is inserted from the right side of the body into the central hole of the body so that the safety buckle and the body are fixed. The safety buckle enables the contacts of the two leads to be positioned, fixed and isolated. With the above structure, the upside-down mounted insulating strip has the advantages that the contacts are fixed, so defects that the contacts are poor in safety are solved; and the dimensional assembling balance is large, so different assembling requirements of contacts having various wire diameters can be satisfied.
