Problems solved by technology

[0008] However, in the shielded cable-terminal fitting attachment structure disclosed in JP-A-2006-244816, since the sleeve of the outer terminal is crimped to the shielding layer in such a manner that the ends of the sleeve overlap each other, part of the outer peripheral surface, so the cross-section of the part of the shielded cable inside the crimped sleeve tends to show a deformed circle
This means that the radial distance between the core wire (conductor) and the shielding layer is not uniform, resulting in irregular impedance

Embodiment 2

[0081] Next, reference will be made to FIGS. 11A and 11B to Figure 14 A shielded connector 2 according to a second embodiment of the present invention is described.

[0082] FIG. 11A is an exploded perspective view of the shield connector 2 according to the second embodiment, and FIG. 11B is a perspective view of the outer terminal 80 viewed from the insulation-covered crimping portion 42 side. Figure 12 is a perspective view of the shielded electrical cable 30 to which the outer terminal 80 is fully attached. Figure 13 is a sectional view of the shielded electrical cable 30 to which the outer terminal 80 is fully attached. Figure 14 It is a developed view of the external terminal 80 .

[0083] The shielded connector 2 according to the second embodiment differs from the shielded connector 1 according to the first embodiment in that the outer terminal 80 of the former also has a braided disassembly preventing tape portion 81 . The rest of the configuration of the shielde...

Abstract

A shielded connector includes a shielded cable, an inner terminal and an outer terminal. The shielded cable includes a conductor, an insulation cover covering the conductor, a shield layer covering the insulation cover, and an outermost insulation cover covering the shield layer. The inner terminal is connected to the conductor. The outer terminal houses the inner terminal and includes a shield crimping portion which is crimped on the shield layer. The shield crimping portion includes a pair of barrel pieces having end portions formed with an engagement projection and an engagement recess, respectively, that are engaged with each other so that the shield crimping portion is crimped on an exposed portion of the shield layer exposed from the outermost insulation cover so as to be a substantially true circle in cross section.
