Definitions

• the present invention is related to a cable connecting structure for an electrical connector, and specifically concerns a cable connecting structure of an electrical connector which is suitable for the connection of multiple coaxial cables.
• the electrical connector 200 shown in Figure 11 has been known as an electrical connector for multiple- conductor cables.
• a flat cable 220 which has signal wires 202 and ground wires 204, and which is positioned on a retaining frame 222, is connected to this electrical connector 200.
• the electrical connector 200 has an insulating base 206, and ground plates 208 which are disposed on both surfaces of the base 206.
• Contact positions 210 which have slots 212 protrude from the rear end of the ground plates 208.
• the ground wires 204 and signal wires 202 of the flat cable 220 are respectively connected to the slots 212 and to press fit type terminals (not shown in the figures) .
• the cable connected to the electrical connector described above is a flat cable 220, it is easy to cause the end portions of the ground wires 204 and signal wires 202 to extend parallel to each other.
• the object of the present invention is to provide a cable connecting arrangement for an electrical connector which allows easy assembly even in the case of circular separated cables .
• the cable connecting arrangement for a cable connector is characterized by an insulating housing that has a plurality of ground and signal terminals in which the ground wires and signal wires of an electrical cable are connected to corresponding terminals, the terminals are press fit type terminals.
• a cable sub- assembly is used in which a grounding member with a plurality of protruding ground plates is disposed along one edge of a main body . The ground wires are connected to the ground plates, and the signal wires are shifted approximately one-half pitch from the ground plate, and the ground plates.
• Figure 1 is a plan view which illustrates of an electrical connector using the cable connecting arrangement for an electrical connector provided by the present invention.
• Figure 2 is a front view of the electrical connector shown in Figure 1, as seen from the direction indicated by arrow A.
• Figure 3 is a plan view which is similar to Figure 1, having the covers removed.
• Figure 4 is a partial enlarged plan view showing the interior of the electrical connector.
• Figure 5 is a plan view showing the connection of the grounding member to a carrier strip.
• Figure 6 is side view of the grounding member shown in Figure 5, as seen from the direction indicated by arrow B.
• Figure 7 is a plan view of the end portion of the cable sub-assembly.
• Figure 8 is a side view of the end portion of the cable sub-assembly.
• Figure 9 is a sectional view along line IX- IX of Figure 4.
• Figure 10 is a front view which illustrates the relationship between the ground plates and the pressing contact parts.
• Figure 11 is a perspective view which illustrates a prior art cable connecting structure for an electrical connector.
• Figure 1 is a plan view which shows the external appearance of an electrical connector (hereafter referred to simply as a "connector") using the cable connecting arrangement for an electrical connector provided by the present invention.
• Figure 2 is a front view from the direction indicated by arrow A in Figure 1.
• the electrical connector 1 has insulative covers 4, 4' which are used facing each other in a two-part construction, and screws 6 used for attachment to the mating connector (not shown in the figures) , which are located at both ends of the covers 4, 4'.
• a cable jacket 150 accommodates a plurality of coaxial cables 100 (hereafter referred to simply as "cables") (see Figure 3), and a heat- shrinkable tube 150 which seals the end portion of the cable jacket 150.
• the covers 4, 4' are fastened together into a unit by means of mutual latch engagement, screws or the like.
• a metal shell 10 which is engaged with the mating connector protrudes from the front end 8 of the cover 4.
• the shell 10 has a long, slender, substantially rectangular shape, with insulation displacement contact (IDC) terminals 20 being disposed in two rows inside this shell 10.
• IDC insulation displacement contact
• Figure 3 is a plan view which is similar to Figure 1, but which shows the connector 1 with the covers 4, 4' removed.
• Figure 4 is a partial enlarged plan view of the interior of the connector 1.
• a metal braid 156 used as shielding extends from the end portion 154 of the cable jacket 150;
• a plurality of independent cables 100 protrude from this end portion 154.
• the braid 156 surrounds a bundle of cables 100.
• the outer insulation 101 of the cables 100 also is stripped from the tip portions, so that the inner insulation 110 ( Figure 4) of the cables 100 is exposed, and the cables 100 are connected to corresponding IDC terminals 20.
• the details of this construction will be described later.
• the front portions of the respective IDC terminals 20 are surrounded by the shell 10 in order to provide electromagnetic shielding.
• the exposed cables 100 protruding from the tip portions of the braid 156 and the rear portions of the IDC terminals 20 are covered by a shield cover 22 which has a two- part structure.
• This shield cover 22 is fastened to the braid 156 by means of anchoring claws disposed on the rear portion of the shield cover 22, and the front portion 23 of the shield cover 22 is engaged with the periphery of the shell 10. It is desirable to improve the impact resistance of the connecting structure by sealing with a filler such as ethylene - vinyl acetate or the like inside the shield cover 22. Furthermore, after the heat- shrinkable tube 152 is moved in the direction indicated by arrow X from the position shown in the figures, this tube is shrunk by heating so that the end portion 154 of the outer covering 150 and the braided wire 156 are sealed.
