Welding spots behind the jumper wire coil are eliminated, and the double-socket connection is adopted, so that welding is not needed during installation, and the problem that the traditional jumper wire coil is difficult to install is avoided.

In this embodiment, the TIP1 and TIP2 ends, the RING1 and RING2 ends, and the SLEEVE end of the jack are named according to the respective ports contacted by the TIP, RING and SLEEVE ends of the plug inserted into the jack. When the plug is inserted into the jack, the TIP1 end of the jack that contacts the TIP end of the plug, the RING1 end of the jack that contacts the RING end of the plug, and the jack sleve end that contacts the jack sleve end.

In this embodiment, the duplex receptacle is a single component that integrates the upper row of receptacles and the lower row of receptacles. For example, 2 duplex sockets with the same structure are assembled on a circuit board, so that a jumper unit is formed. If a jumper unit is produced as a standard component, it is a minimum specification jumper module.

For convenience of description, the audio jumper device of the embodiment is assembled by using n jumper units or n minimum-specification jumper modules, that is, one jumper unit is only composed of one front duplex socket and one rear duplex socket.

In this embodiment, one jumper unit should be formed by 2 duplex sockets with an aperture of 6.35mm, and each duplex socket is provided with an upper row of sockets and a lower row of sockets respectively. When the audio jumper device is assembled, one duplex socket in the jumper unit is set as a front duplex socket, and an upper row of jacks and a lower row of jacks are respectively arranged on an upper row and a lower row of a front panel of the casing; the other duplex socket is set as a rear duplex socket, and the upper row of jacks and the lower row of jacks are arranged on the upper row and the lower row of the rear panel of the casing. The two duplex sockets are all welded on the same PCB, and pins between the front duplex socket and the rear duplex socket are connected through the PCB without additional welding wires. The front duplex socket on the front panel is used for connecting an audio jumper, and the rear duplex socket on the rear panel is used for connecting front and rear end signals.

A jumper unit is shown in fig. 5 with a front duplex receptacle and a rear duplex receptacle. The front duplex socket and the rear duplex socket in the jumper unit are both arranged on the same PCB. Wherein the upper row of sockets and the lower row of sockets of the front duplex socket or the rear duplex socket are respectively provided with a TIP1 end, a TIP2 end, a RING1 end, a RING2 end and a SLEVE end, wherein the TIP1 end, the TIP2 end, the RING1 end and the RING2 end are all set as normally closed ends of a flexible switch.

The TIP2, RING2 and slide ends of the upper row of jacks of the front-duplex receptacle are connected to the TIP2, RING2 and slide ends of the lower row of jacks of the front-duplex receptacle, respectively, via a PCB circuit board. In addition, the TIP1, RING1 and SLEEVEs of the top row of jacks of the front duplex receptacle are connected to the TIP1, RING1 and SLEEVEs of the top row of jacks of the rear duplex receptacle by a PCB circuit board, and the TIP1, RING1 and SLEEVEs of the bottom row of jacks of the front duplex receptacle are connected to the TIP1, RING1 and SLEEVEs of the bottom row of jacks of the rear duplex receptacle by a PCB circuit board. The TIP1 terminal is used for signal connection, the RING1 terminal is used for signal connection, and the SLEEVE terminal is used for grounding.

The audio jumper device of the embodiment is also correspondingly provided with a plurality of audio jumpers, and two ends of each audio jumper are provided with plugs. The plug of the audio jumper is matched with the upper row of sockets and the lower row of sockets of the front duplex socket, and can be easily inserted into or pulled out of the sockets.

The plug carried by the audio patch cord is a 3-core plug including a TIP terminal, a RING terminal, and a slide terminal, wherein the TIP terminal terminates the signal +, the RING terminal terminates the signal, and the slide terminal terminates the ground.

The TIP1 end and TIP2 end of the upper or lower row of jacks of the front duplex receptacle, the RING1 end and RING2 end are respectively set as the normally closed ends of the elastic switches, and the slide end is set as the fixed end. When the upper row of jacks or the lower row of jacks of the front duplex socket is inserted into the audio jumper plug, the TIP end and the RING end of the plug enable the normally-closed end of the elastic switch between the TIP1 end and the TIP2 end of the upper row of jacks or the lower row of jacks, and between the RING1 end and the RING2 end to be automatically disconnected.

When the socket is used, a signal source or front-end equipment is connected with the upper row of jacks of the rear duplex socket through a cable with a plug, and the rear-end equipment is connected with the lower row of jacks of the rear duplex socket through a cable with a plug. Therefore, the connection mode of external signal input or output of the whole audio jumper device is changed into a plug connection mode.

The working principle is as follows:

the signal path of the audio jumper device of this embodiment is as shown in fig. 6, and it is assumed that n jumper units are provided in the audio jumper device, and if the signal input by the 2 nd unit is to be jumped to the output of the n nd unit, the specific method is to insert one end plug of the audio jumper into the upper row of the front duplex receptacle of the 2 nd jumper unit, and insert the other end plug of the audio jumper into the lower row of the front duplex receptacle of the n nd jumper unit, at the same time, the upper row of the front duplex receptacle of the 2 nd jumper receptacle is composed of a TIP1 end, a TIP2 end, a RING1 end and a RING2 end, and the upper row of the front duplex receptacle of the n nd jumper receptacle is composed of a TIP1 end, a TIP2 end, and a RING1 end and a RING2 end, which are all automatically disconnected.

After the connection in the above way, the front end signal of the 2 nd path is input from the upper row socket of the back duplex socket of the 2 nd unit, sequentially passes through the TIP1 and RING1 of the upper row socket of the front duplex socket of the 2 nd unit, the TIP and RING of the audio jumper, the TIP1 and RING1 of the lower row socket of the front duplex socket of the nth unit, and is output from the lower row socket of the back duplex socket of the nth unit to the back equipment of the nth path, and at the same time, the normally closed ends of the elastic switches of the TIP1 and TIP2 of the upper row socket of the front duplex socket of the 2 nd and nth path, the RING1 and RING2 of the RING have been automatically disconnected, so that the back equipment of the 2 nd unit and the front end equipment of the nth unit are automatically disconnected from the signal path. Unlike traditional jumper disks, the novel audio jumper device is additionally provided with a rear duplex socket, so that the signal input of a signal source or front-end equipment and the connection of rear-end equipment are changed into plug connection by traditional direct welding connection.

The function of the above operating mode is illustrated as follows: if the fault that the backward equipment of the nth path has no signal occurs, the fault point can be checked through the audio jumper, the audio jumper is respectively inserted and connected with the upper row of jacks of the 2 nd unit (or other units with signals) and the lower row of jacks of the nth unit, the signal output of the 2 nd path is led to the backward equipment of the nth path, if the backward equipment of the nth path has a signal at this time, the fault reason is that the front-end equipment of the nth path has no signal output, the front-end equipment needs to be checked, and if the nth path still has no signal at this time, the backward equipment of the nth path has a problem, and the backward equipment needs to be further checked. In addition, if the temporary scheduling signal is needed, the 2 nd path signal is temporarily scheduled to the nth path, and the same operation can be adopted.

The plug and the duplex socket of the embodiment are both a standard three-core audio plug and a duplex socket with the aperture of 6.35mm, and are welded and installed by a PCB. Because the 6.35mm plug and the socket are standardized elements, the plug and the socket have the advantages of wide application, mature technology, reliable performance, easy purchase, price greatly lower than that of a special plug and socket, and contribution to batch production and cost reduction.

The novel audio jumper device is connected by a plug and a socket, so that the installation of equipment is greatly facilitated, all related signal wires are welded with plugs before installation and are distributed at positions corresponding to the sockets, and during use, the plugs are inserted into the sockets, and if the plugs need to be changed or detached for maintenance, the plugs are also pulled out quickly.

Fig. 7 shows a finished 48-port novel audio jumper device, which is assembled by 24 jumper units. The front panel 1 in the casing is provided with 48 jacks, 24 upper-row jacks 3 and 24 lower-row jacks 4; 48 jacks are also arranged on the rear panel 2 of the casing, and 24 upper-row jacks 3 and 24 lower-row jacks 4 are also arranged as in the arrangement of the front panel.

For convenience of use, the n jumper units can also be integrated into one jumper module with 2 x n jacks. In order to enable the audio jumper device to have more jacks, the size of the duplex socket can be correspondingly reduced, for example, a three-core socket with the aperture of 6.35mm is replaced by a three-core socket with the aperture of 3.5mm, so that the audio jumper device with the aperture of 1U can achieve the specification of 96 ports.

The above-mentioned embodiments of the present invention do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
