Problems solved by technology

Because the main connector 104 of the existing branch cable needs to realize the cable bifurcation, each terminal of the connector needs to be welded into the core wire 101 and the jumper core wire 102 at the same time, so that the main connector 104 needs to be connected 2 times the amount of cables, the cable welding density is 1 times that of conventional cables, and because all the forks are realized on the main connector 104, it is very difficult to process the main connector and the yield is low

Embodiment Construction

[0028] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] Such as figure 2 As shown, the branched cable of the present invention includes a multi-core access cable, a multi-core jumper cable, and a connector containing multiple terminals. Wherein, the connector is in the form of a connector, such as a high-density D-type connector or a SCSI connector. exist figure 2 In the example, the connectors include connectors 202 and 204, that is, the number of connectors is 2. It should be understood that the number of connectors is set according to actual needs, and the number in this example does not constitute a limitation. For example, there may be three connecting pieces or others, that is, the number of connecting pieces may be two or more.

[0030] The multi-core access cable has multiple core wires, each core wire can transmit one core wire signal, and all the core wire signals form a s...

Abstract

A branch cable is disclosed by the present invention, which includes a multiconductor inbound cable, a multiconductor jumper cable and at least two connectors with multiple terminals. Each conductor of the multiconductor inbound cable is used for transmitting one channel of conductor signal, and all the conductor signals constitute a signal set. Each conductor of the multiconductor inbound cable is directly connected to one terminal of the connectors, respectively. The terminals directly connected with the conductors of the multiconductor inbound cable are distributed over at least two connectors. Each terminal directly connected with a conductor of the multiconductor inbound cable is respectively connected to one terminal of other connectors via the multiconductor jumper cable bridged over the connectors, so that each connector can receive all the conductor signals of the signal set, and any terminal of each connector can receive at most one channel of conductor signal. The branch cable provided by the present invention can decrease the difficulty of the connector manufacturing.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a branch cable and equipment using the branch cable. Background technique [0002] Forked cables are widely used in communication products, and are mainly used to realize multi-point signal transmission, or for device interface backup. Among them, the high-density multi-core branch cable is an important way for communication equipment to realize the backup of E1 and T1 interface units. figure 1 It is a schematic diagram of conventionally implementing E1 and T1 interface backup. Through a branch cable, a group of E1 signals can be simultaneously transmitted to the E1 and T1 interface units of two mutually backup interface boards 108 and 109 of a device. In this way, when an interface board, such as the interface board 108, is abnormal, the backup interface board 109 can be used instead of the interface board 108 to process the E1 signal. This method of using a bifurcated c...
