Abstract

The invention discloses a branch cable and equipment employing the same. The branch cable comprises a multi-core access cable, a multi-core jumper cable and at least two connecting pieces with a plurality of wiring terminals, wherein each core wire of the multi-core access cable is used for transmitting a path of core wire signals, and all the core wire signals form a signal set; each of the corewires of the multi-core access cable is directly connected to one wiring terminal of the connecting pieces; the wiring terminals directly connected with the core wires of the multi-core access cable are at least distributed on the two connecting pieces; and each wiring terminal directly connected with the core wire of the multi-core access cable is connected with one wiring terminal of each connecting piece through the multi-core jumper cable which is jumped among the connecting pieces, so that all the core wire signals of the signal set can be accessed to each connecting piece, and at most one path of the core wire signals is accessed to any wiring terminal of each connecting piece. The manufacturing difficulty of the branch cable can be remarkably reduced.

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...

Embodiment Construction

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

[0029] like 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 sign...
