Abstract

An electric connecting cable includes an insulative seat, multiple terminals and multiple wires corresponding to the terminals. The terminals are buried in the insulative seat. Each terminal has a soldering leg. Each soldering leg penetrates out of the insulative seat. The soldering legs are arranged in a row. Each soldering leg is disposed with a concave soldering groove. Each soldering groove has a notch and a slope outward extended from an edge of the notch. Each wire has a soldering end. Each soldering end is accommodated in corresponding one of the soldering grooves. Each soldering end is separately soldered to corresponding one of the soldering legs. Each wire is extended along a longitudinal direction of corresponding one of the soldering legs soldered thereto.

First claim

What is claimed is:

1 . An electric connecting cable comprising:
an insulative seat; multiple terminals, buried in the insulative seat, each terminal comprising a soldering leg, the soldering leg penetrating out of the insulative seat, multiple soldering legs arranged in a row, each soldering leg comprising a soldering groove disposed concave into one side of the soldering leg, the soldering groove comprising a notch penetrating a bottom of the soldering groove to another side of the soldering leg and a slope defined on an internal surface of the soldering groove, and the slope outwardly extended from an edge of the notch toward an opening of the soldering groove; and multiple wires, disposed corresponding to the terminals, each wire comprising a soldering end, the soldering end accommodated correspondingly in the soldering groove, the soldering end soldered to the soldering leg, and each wire extended along a longitudinal direction of the soldering leg being soldered, wherein the slope is a concavely curved surface, and the soldering end is accommodated in the notch and is supported by the slope.

2 . The electric connecting cable of claim 1 , wherein at least one of the soldering legs is correspondingly soldered with multiple soldering ends.

3 . The electric connecting cable of claim 1 , wherein multiple soldering ends are jointly supported by the slope.

4 . The electric connecting cable of claim 1 , wherein a diameter of the soldering end is greater than a width of the notch.

5 . The electric connecting cable of claim 1 , wherein the slope is a plane, and the soldering end is accommodated in the notch.

6 . The electric connecting cable of claim 5 , wherein multiple soldering ends are jointly accommodated in the notch.

7 . The electric connecting cable of claim 5 , wherein a diameter of the soldering end is less than a width of the notch.

8 . The electric connecting cable of claim 1 , further comprising an insulative block, wherein the soldering end is buried in the insulative block.

9 . The electric connecting cable of claim 1 , wherein each wire comprises a core and an insulative layer covering the core, and in each wire, the core is exposed from the soldering end and soldered to one of the terminals.

10 . The electric connecting cable of claim 1 , wherein each terminal is a strip-shaped metal sheet.

11 . The electric connecting cable of claim 1 , wherein the terminals comprise multiple grounding terminals connected to each other, and each grounding terminal is transversely extended and connected with another grounding terminal arranged adjacently.

12 . The electric connecting cable of claim 11 , wherein each terminal comprises at least one connecting end, the connecting end of each terminal is arranged corresponding to the soldering leg, and in two of the grounding terminals adjacently arranged, the connecting end on one of the grounding terminals is transversely connected to another connecting end on another one of the grounding terminals adjacently arranged by a spanning section.

13 . The electric connecting cable of claim 12 , wherein the terminals comprise multiple signal terminals separated from each other, and the spanning section crosses at least one signal terminal.
