Description

Cable connector combination

The present invention relates to a cable connector combination, and more particularly to a cable connector combination for high speed transmission.

In the cable connector combination, a spacer is often used. 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 Chinese Patent Publication No. CN2697881Y discloses a cable connector including an insulative housing, a plurality of conductive terminals, an insulating spacer, and a cable provided with a plurality of core wires. Each of the conductive terminals 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 of the conductive terminal extends through the locating hole of the insulating spacer and is exposed to the rear side of the insulating spacer for soldering with the corresponding core of the cable. 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 quality of the soldering will be affected because the conductive terminal and the cable are easily moved. Therefore, it is necessary to provide a cable connector whose insulating spacer is provided with a support portion for supporting the tail portion of the conductive terminal, thereby overcoming the above-mentioned welding deficiency.

The Chinese Patent Publication No. CN2539299Y discloses a cable connector including an insulative housing, 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 insulating body. The insulating spacer is provided with a first surface, a plurality of trapezoidal channels disposed on the first surface, and a stop plate perpendicular to the first surface. Conductive terminals are housed in trapezoidal slots The track is limited by the trapezoidal channel 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 of the cable, the corresponding wire and the connecting end of the conductive terminal are respectively connected and restricted by the trapezoidal channel. During welding, the wires and the connecting ends are supported by the insulating spacers, so that the cables and the conductive terminals are reliably electrically connected. However, the interlocking of the insulating spacer and the insulative housing is only matched to the flange of the insulative housing through both sides of the stop plate. When forming an outer protective sleeve, a high-speed flowing plastic material must be injected into the mold. However, the molding process must provide a high voltage to keep the plastic material flowing continuously, so that the insulating spacer is susceptible to movement and moves relative to the insulating body, thereby affecting the electrical connection of the conductive terminals to the wires of the cable. In practice, in order to facilitate the outlet, the cable is often bent and then the outer protective sleeve is formed. However, the bent cable cannot be positioned on the insulating partition. When the outer protective sleeve is formed, the high-speed flowing plastic will The cable after the bending is impacted by the mess, thereby affecting the electrical connection between the conductive terminal and the wire of the cable.
