Embodiment

Now lift following examples and by reference to the accompanying drawings structure of the present invention and effect be described in detail.

As shown in Figure 3 to Figure 4, the first embodiment of the present invention provides a kind of female terminal 3, comprise a socket 31 and base 32, wherein: the inner peripheral surface of socket 31 abuts has the metal clips 1 being rolled into hollow circular cylinder, with the grafting male terminal that female terminal 3 is corresponding therewith; Base 32 is connected with electric wire, and for transmitting the electric current from the power supply such as engine or battery, in the present embodiment, the material of metal clips 1 is copper.

Again as shown in Figure 1, metal clips 1 comprises the lamellar body 10 of a rectangle, and is located at first hollow-out parts 11 and second hollow-out parts 12 of multiple strips of lamellar body 10, and in the present embodiment, the quantity of the first hollow-out parts 11 and the second hollow-out parts 12 is 12.Wherein, each first hollow-out parts 11 and each second hollow-out parts 12 are equidistant and along the length of side direction L linear array of lamellar body 10, form the arrangement mode of a rectangular array.In addition, lamellar body 10 has 4 virtual road punch line P, thus by the mode of mechanical stamping, between adjacent two the first hollow-out parts 11 and adjacent two the second hollow-out parts 12, be bent to form a protuberance 13 respectively, each protuberance 13 is bent into wavy and has at least two end points 14 be positioned on punch line P.Certainly, end points quantity also can be reduced to one by protuberance of the present invention.

Thus, as shown in Figure 2, metal clips 1 can be in addition curling along length of side direction L towards the protrusion direction of each end points 14, and then form the cylinder of a hollow, allows each end points 14 be positioned at the inner surface of foregoing cylindrical body simultaneously.Afterwards, this cylinder just can be positioned in the socket 31 of female terminal 3.When a male terminal (not shown) is inserted in female terminal 3, the end points 14 of each protuberance 13 will directly contact with male terminal, therefore there is larger contact area and the product of big current can be applicable to, and each protuberance 13 is one-body molded and two ends connect lamellar body 10 securely, so a large amount of Plug Actions can be born, there is higher useful life.

Those skilled in the art except changing the quantity of each protuberance upper extreme point, or outside the quantity of change hollow-out parts, can also adjust the configuration mode of hollow-out parts in the present invention.Refer to shown in Fig. 5, for the second embodiment provided by the present invention, structure substantially with the first embodiment of metal clips 1 is similar, its difference be in: each first hollow-out parts 11 and each second hollow-out parts 12 are staggered along the length of side direction L of lamellar body 10, makes each protuberance 13 with corresponding first hollow-out parts 11 or the second hollow-out parts 12 respectively of the direction perpendicular to length of side direction L.Thus, it is more even that the metal clips of the second embodiment can allow each end points 14 scatter, to promote the impact that terminal repeatedly plugs.

The present invention separately provides the 3rd embodiment, and as shown in Figure 6, structure substantially with the second embodiment of metal clips 1 is similar, and its difference is in and extends towards the protuberance 13 of correspondence with the direction perpendicular to length of side direction L in each second hollow-out parts 12.Thus, each second hollow-out parts 12 will be greater than each first hollow-out parts 11 perpendicular to the length of length of side direction L, therefore, it is possible to the protuberance 13 made way between two adjacent the second hollow-out parts 12 is bent to form three end points (i.e. punch line P pass through position).

Finally; what must again illustrate is; the composed component that the present invention is disclosed in the aforementioned embodiment is only and illustrates; not be used for limiting the scope of patent protection of this case; such as other structural changes easily expected; or the alternate variation of other equivalence elements, all should contain by the scope of patent protection of this case.
