Embodiment
Referring to Fig. 1～Fig. 7, electrical connector comprises first link 1 and second link 2, and described first link 1 is made by different electric conducting materials with second link 2; Described first link 1 and second link 2 are fixed together by the joint face that cooperatively interacts.Link by unlike material connects the element of unlike material, makes that the material of link is consistent with the material of element, and the big problem of contact resistance avoided occurring phenomenon overheated and the generation oxide layer when the element that can solve unlike material interconnected.
Described first link 1 is made by copper material, and described second link 2 is made by aluminium, can connect aluminium matter lead and copper element easily, adopts lower copper material and the aluminium of price, can reduce the processing and manufacturing cost of joint.Described first link 1 and second link 2 are fixed together by the inclined-plane 3 that cooperatively interacts; The end face of one end of first link 1 and second link 2 is set to inclined-plane 3, and the inclined-plane 3 of the two matches in the mode of face contact mutually.Perhaps, described first link 1 and second link 2 are fixed together in the mode of joggle; The end face of one end of first link 1 and second link 2 is set to step surface, and step surface is a shiny surface, and the step surface of the two cooperatively interacts in the mode of face contact, forms joggle.Or described first link 1 and second link 2 are fixed together by the honeycombed face 4 that cooperatively interacts; The end face of one end of first link 1 and second link 2 all is set to step surface, and the surface of the step surface of the two is arranged to 4, two honeycombed faces 4 of honeycombed face and is cooperatively interacted in the mode that face contacts; Honeycombed face 4 is: the surface of the step surface of one of them link is provided with a plurality of grooves, and the corresponding step surface of another link is provided with projection a plurality of and that these grooves are complementary, and described groove and projection preferably are profile of tooth; When two surfaces are in contact with one another, these projectioies and groove snap together mutually, mode by welding welds together two honeycombed faces 4 again, can strengthen two connection reliability between the link, to avoid the phenomenon that fracture takes place at the contact-making surface place two links.When two links interconnected by above these three kinds of modes, the contact site was a contact-making surface, and the area of contact is big, can reduce the contact resistance of contact site, improves the reliability that connects between the two.
Described first link 1 is mutually permanently connected in the mode of welding with second link 2 and is in the same place, and the reliability height of connection is simple.Described first link 1 is provided with the screw 5 of axis normal in the thickness direction of first link 1; Described second link 2 is provided with semi-circular recesses 6; Described semi-circular recesses 6 be positioned at second link 2 one side the middle part and be provided with in the mode of extending along its length, the middle part of second link, 2 another sides is provided with the semicircle boss 7 that extends along its length; Be provided with the screw 5 of axis normal in the thickness direction of second link 2 in the both sides of semi-circular recesses 6; Adopt cover plate 8 that lead is pressed in the semi-circular recesses 6; The one side of described cover plate 8 is provided with arc groove 9, and another side is provided with arc convex 10, is provided with the screw 5 of axis normal in the thickness direction of cover plate 8 in the both sides of arc groove 9.On the both sides of described semi-circular recesses 6, every side is provided with the screw 5 more than three.After lead peelled off the outer layer insulation skin, bare wire is placed in the semi-circular recesses, cover plate is pressed on second link 2 and then and fixes with screw bolt and nut; By a plurality of cover plates, aluminium matter lead can be pressed in the semi-circular recesses of second link 2 tightly, the tightness of lead is good, can avoid taking place the phenomenon of wire dropping.
Because two links adopt copper material and aluminium manufacturing respectively, thereby make the present invention be particularly useful for connecting aluminium matter element and copper element.
