Abstract
To prevent the disconnection of a core at a caulking part without increasing the number of components by forming one edge of a cord drawing side of the inner wall surface of a cord connection part, which is provided at a tip of a cord to be connected and which has a core insertion space to be caulked after inserting the core, with a retreat surface so as to be separated from the outer surface of the core toward the cord drawing side. A caulking part 21 having a U-shaped cross section formed at a rear end of a pair of metal blades formed as electrical terminals of a plug body, which is made of the vinyl chloride resin, of a power source plug and to be inserted into a blade rest of a power source socket is formed with a curved surface 24 over the whole of the core insertion side edge so as to be curved outside toward the core insertion side. Thickness of the curved surface 24 is gradually reduced in the core inserting direction, and furthermore, since the outside surface of the upper edge is chamfered so as to be formed thin, caulking after inserting the core 31 of a tip of a cord 3 into the caulking part 21 is facilitated. Contact of an edge 26 of the caulking part 21 with the core 31 is prevented by existence of the curved surface 24 and the flare shape formed like a sector in the rear edge direction.
Description
The present invention relates to electric terminal, specifically, the present invention relates to the improved shape of the terminal that union pieces such as attaching plug, supply socket and binding post had (for example the pin base of the pin of attaching plug and supply socket etc.) to electric equipments such as electrified product or OA equipment power supplies usefulness.
Be located at the attaching plug on the power line of electric equipments such as electrified product or OA, generally by a pair of pin and header body constitute (with reference to as Japanese patent of invention communique is disclosed 1998 No. 308250).Pin inserts usefulness to connector assemblies such as socket or table taps.Header body is the coupling part of protection pin and electric wire and concerns being supported fixing usefulness between the pin with the position of regulation.This header body forms with insulating material.
Described pin and electric wire are connected by riveted joint processing (crimping).Specifically, as shown in Figure 8, locate, be pre-formed caulking part b (this caulking part b is a U word shape riveting the processing starting section, has heart line in inside and inserts the space) in the rearward end (bottom of Fig. 8) of pin a.Under the state after the heart line d with electric wire c front end inserts this caulking part b, b rivets processing to caulking part, thereby pin a is fixedly mounted on the electric wire front end.
In addition, can insert the pin base of supply socket of described attaching plug or the pin base on the binding post that the equipment that is located at connects usefulness and be connected with electric wire too.That is, form and above-mentioned same caulking part at the rearward end place of the pin base of these supply sockets and binding post.Under the state after the heart line with the electric wire front end inserts this caulking part, caulking part is riveted processing, thereby pin base is installed on the electric wire front end.
In addition, when the caulking part b to these pins a and pin base rivets the processing operation, be used for protecting the divergence process of electric wire c heart line d.Below, describe with regard to this divergence process.The imaginary line of Fig. 8 represents to rivet anchor clamps e.So, the riveted joint anchor clamps e end edge of only reserving caulking part b is riveted processing to other parts (A part among Fig. 8).Its result, the deflection of the end edge of caulking part b just lacks than other parts, and this part becomes the expansion shape of expanding gradually to the end edge of caulking part b.By this processing, the heart line d of electric wire c just is difficult to the EDGE CONTACT with the end edge of caulking part b, thereby can prevent the broken string of the heart line that produced because of contact.
