Description

Cable fixing structure of high speed communication cable connector assembly

The present invention relates to a cable connector assembly for high speed communication, and more particularly, to a cable fixing structure of the cable connector assembly for high speed communication, which is installed inside the cable connector assembly for high speed communication so that the cable can be fixed and fixed.

Typically, equipment such as exchanges initially relayed only voice signals, but recently it has been requested to relay binary data, including text and image information. Such devices consist of a number of circuit blocks including many printed board assemblies (hereinafter simply referred to as 'PBAs') to relay the voice and data of multiple subscribers. In addition, these devices need to be able to transmit data at high speeds and accommodate as many subscribers as information grows in size, and require processing power to process data at very high speeds.

As a result, the signal transmitted between the circuit blocks and the PBAs in the equipment occupies a certain frequency, for example, a band of 240 MHz or more, and the equipment is reduced in size to minimize the occupied area.

In addition, in the aforementioned equipment, the circuit blocks and the PBAs are electrically connected to each other by a transmission cable, and the transmission cables are connected or separated from the circuit blocks or the PBA by the cable assembly. That is, the cable assembly is installed at the end of the transmission cable so that the transmission cable is easily connected to or disconnected from the circuit block or PBA of the equipment. These cable assemblies must be minimized as the size of large transmission equipment becomes smaller and must be capable of transmitting high frequency signals of 240 MHz or higher processed in circuit blocks and PBAs without distortion.

Due to this size limitation, an unshielded cable assembly having a pitch of 2 mm and a shielded assembly for transmitting a high frequency signal without distortion have been proposed. However, these cable assemblies have a problem in that the manufacturing process is complicated and the defect rate is high because the cable assembly is manufactured by inserting the contacts connected to the cable to the component formed by the first injection and then proceeding to the second injection.

In order to solve such a problem, a cable assembly and a method of manufacturing the same have been disclosed by Patent Application No. 97-46091, but there is a problem that connection failure may occur due to external impact by storing the cable.

The present invention has been made to solve the above-described problem, the object of the present invention is to position and fix the cable inside the cable connector assembly.

The purpose of this is to fix the cable inside the housing to prevent connection failure by fixing the cable in the event of external impact.
