DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a line slow connector combination, and more particularly to a line slow connection Is combination for high speed transmission. [Prior Art] A spacer is often used in the line slow connector assembly. The main function of the spacer is to align the tail of the conductive terminal housed in the insulating body with the core of the cable while providing support for soldering between the tail and the core. The National Patent Publication No. CN2697881Y discloses a cable connector including an insulating body, a plurality of conductive terminals, an insulating spacer, and a cable provided with a plurality of core wires. Each of the conductive terminal packages 1 includes a retaining portion, a mating portion extending forward from the retaining portion, and a tail portion extending rearward from the retaining portion. When the conductive terminal is positioned in the insulating body, the insulating spacer is coupled to the rear end of the insulating body. The tail portion of the conductive terminal extends through the positioning hole of the insulating spacer and is exposed to the rear side of the insulating spacer for soldering to the corresponding core of the slow line. However, since the tail portion of each of the conductive terminals protrudes from the rear end of the insulating spacer in a floating manner, when the tail portion of the conductive terminal is soldered to the cable, the conductive terminal and the cable are easily moved, so that the quality of the soldering is affected. Therefore, it is necessary to provide a cable connector, and the insulating spacer is provided with a supporting portion for supporting the tail portion of the conductive terminal, thereby overcoming the shortage of the above welding. The Chinese Patent Publication No. CN2539299Y discloses a cable connector comprising an insulating body, a conductive terminal assembled in the insulating body, a cable soldered to the conductive terminal, and an insulating spacer assembled to the rear end of the body. The insulating spacer is provided with a first surface, a plurality of channels formed on the first surface, and a stop plate perpendicular to the first surface. The conductive terminals are received in the lion channel and are controlled by trapezoidal channels, so that the conductive terminals are not offset left and right and are not connected to each other. When the conductive terminal is soldered to the wire conductor: the corresponding wire and the connection terminal of the conductive terminal are respectively connected and restricted by the trapezoidal channel, the welding, the wire and the supporting side of the insulating spacer are supported, so the wire inspection conductive terminal reaches reliable power Sexual connection. However, the shipboard and the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ When molding the outer protective sleeve, 'the high-speed flowing plastic must be injected into the mold. However, the molding process must provide high pressure to keep the plastic material flowing continuously. Therefore, the insulating county has a relatively high insulation relative to the insulation, thus affecting the conductive terminals. In connection with the electrical connection of Lai's wire, in order to make the money scale, Wei will fold the f-fu cake cover, and the folded wire can not be positioned on the insulating partition. At the time, the high-speed flow of plastic: will be 1377737 will be the line after the bending _ hit the mess of seven people, thus affecting the electrical connection between the conductive terminal and the wire conductor. Therefore, it is indeed necessary to design a cable connector combination to overcome the above-mentioned problems. The present invention aims to provide a wire-type connector assembly with an improved insulating spacer to achieve conductive terminals and cables. Reliable electrical connection.
