The cables use ordinary 0.4mm², 0.75mm², 1.0mm² and other single-core wires or wiring cables. Cables generally need to be equipped with a shielding layer and the shielded cable is grounded. For example, in the railway signal room, the ZPW-2000A transmission channel uses a two-core twisted shielded cable, and its shielding layer should be connected to the ground at one end.

[0026] Combine the following Figures 1 to 3 The specific structures of the bundled cable connection joint, the shielded bundled cable and the signal room grounding cabinet of the present invention are described.

[0027] One embodiment of the present invention provides a bundled cable connector, see Figure 1 As shown, it includes a male shell 1 and a female shell 3, wherein a plurality of male connecting terminals 2 are arranged on the male shell 1 to form a plug structure, wherein at least one of the male connecting terminals 2 is connected to the shielded cable of the bundled cable, and the remaining male connecting terminals 2 are respectively connected to a plurality of wiring cables in the bundled cable; a plurality of female connecting terminals 4 are arranged on the female shell 3 to form a plug-in board structure, wherein the female connecting terminals 4 are used to plug into the male connecting terminals 2, wherein at least one of the female connecting terminals 4 is grounded, and the remaining female connecting terminals 4 are connected to components to be wired and connected.

[0028] It can be understood that the bundled cable connector of this embodiment mainly includes two parts, namely the male shell 1 and the female shell 3, which can be coupled into one, wherein the male shell 1 is connected to the end of the bundled cable, and the female shell 3 is arranged on the cabinet of the switching cabinet, and the male connection terminal 2 on the male shell 1 and the female connection terminal 4 on the female shell 3 are plugged into each other to realize the wiring connection between the bundled cables and the racks. It should be understood that a special grounding terminal is provided in each of the multiple male connection terminals 2 and the multiple female connection terminals 4, and the corresponding grounding terminals are plugged in and then connected to the transmission channel lightning protection copper busbar reserved in the cabinet, so as to realize the grounding of the shielded cable of the bundled cable without the need for wire stripping and grounding. The bundled cable connection connector of this embodiment is suitable for grounding shielded cables after bundled cable wiring is adopted in a signal room. The grounding of the bundled shielded cables is achieved by correspondingly plugging the grounding terminals of the male shell 1 and the female shell 3. The positions of the grounded terminals can be uniformly set (for example, the lowest connection terminals are used as the grounding terminals). The construction is convenient. After the construction is completed, the wiring connections are arranged in order, and the overall aesthetics is good.

[0029] In some embodiments of a bundled cable connector of the present invention, the number of male connection terminals 2 on the male housing 1 is the same as the number of female connection terminals 4 on the female housing 3, and the male connection terminals 2 are matched and plugged in one-to-one with the female connection terminals 4. It can be understood that in this embodiment, the male housing 1 and the female housing 3 can be coupled into one body, and an anti-misplugging structure is adopted, so that the male connection terminals 2 and the female connection terminals 4 have a unique matching connection mode.

[0030] In some other embodiments of a bundled cable connection connector of the present invention, both the male shell 1 and the female shell 3 are provided with mounting holes for fixing to a cabinet, so that after the male shell 1 and the female shell 3 are plugged in, the male shell 1 and the female shell 3 are fixed to the cabinet by bolt connectors.

[0031] It is understandable that the female housing 3 is generally arranged on the cabinet of the switching cabinet, and a threaded connection hole is reserved on the cabinet, and a bolt connector can be inserted into the mounting hole on the female housing 3, and the female housing 3 is fixed to the cabinet through the bolt connector. The male housing 1 is connected to the end of the bundled cable, and when the wiring connection is made, the male housing 1 is coupled and plugged with the female housing 3, and then the male housing 1 is also fixed to the cabinet through the bolt connector, so that the wiring connection between the bundled cable and the cabinet is realized.

[0032] In some embodiments of a bundled cable connection connector of the present invention, the male shell 1 and the female shell 3 are made of V-0 grade flame retardant material, specifically, they can be made of phenolic molding compound and polycarbonate plastic composite, wherein the phenolic molding compound can be used as an adhesive and auxiliary agent, and can also play a role of reinforcing the skeleton after curing. Polycarbonate plastic has good and constant electrical insulation in a wide temperature and humidity range, and is an excellent insulating material. At the same time, it has good flame retardancy and dimensional stability. The composite of phenolic molding compound and polycarbonate plastic makes the male shell 1 and the female shell 3 have the characteristics of corrosion resistance, high insulation strength, arc resistance, good flame retardancy, etc.

[0033] Another aspect of the present invention provides a shielded bundled cable, see Figure 2 As shown, it includes an insulating sheath 5, a plurality of wiring cables 6, a male shell 1 of any one of the above embodiments, and a shielding net 7, wherein the plurality of wiring cables 6 are arranged in parallel in the insulating sheath 5; the male shell 1 is arranged at the end of the insulating sheath 5, and the plurality of wiring cables 6 are respectively connected to the male connection terminals 2 of the male shell 1, and the male connection terminals 2 connected to the wiring cables 6 are used for wiring connection; the shielding net 7 is welded to the end of the wiring cables 6 close to the male shell 1 by a shielding cable ring, and the shielding cables constituting the shielding net 7 are connected to the male connection terminals 2 of the male shell 1, and the male connection terminals 2 connected to the shielding cables are used for grounding connection.

[0034] It can be understood that a plurality of wiring cables 6 are covered with an insulating sheath 5 to form a bundled cable, and a male shell 1 is installed at the end of the bundled cable. The plurality of wiring cables 6 in the insulating sheath 5 include oxygen-free copper wires and an insulating sheath wrapped around the outer periphery of the oxygen-free copper wires, and the insulating sheath is a polyvinyl chloride sheath. The wiring cables 6 are placed in the same bundle by the insulating sheath 5 to avoid mixing and interlacing of the wiring cables 6, and reduce interference between the wiring cables 6. The ends of the plurality of wiring cables 6 are respectively connected to a male connection terminal 2 on the male shell 1 in a one-to-one correspondence, so as to achieve neat wiring of the wiring. It should be understood that a 2-3 cm shielding net 7 is left at the end of the bundled cable. The shielding net 7 is connected to the male connection terminal 2 on the male shell 1 through a ground wire after being welded in a ring at the end. The male connection terminal 2 connected to the shielded cable can be used as a grounding terminal, which is correspondingly plugged with the grounding terminal on the female shell 3 in the later stage, and connected to the transmission channel lightning protection copper bus reserved in the cabinet for grounding.

[0035] The grounding of the cable shielding layer includes single-end grounding of the shielding layer and double-end grounding of the shielding layer. When the shielding layer is single-ended grounded, there is an induced voltage between the metal shielding layer at the non-grounded end and the ground. The induced voltage is proportional to the length of the cable, but there is no potential circulation passing through the shielding layer. Single-end grounding utilizes the suppression of potential difference to eliminate electromagnetic interference. This grounding method is suitable for shorter lines, and the induced voltage corresponding to the cable length cannot exceed the safety voltage. Corresponding to the shielded bundled cable of the present invention, a grounding terminal can be set for one end of the bundled cable, and a grounding terminal may not be set at the other end. The end with the grounding terminal is connected to an integrated cabinet or a frequency shifting cabinet, and the ungrounded section can be connected to a combination cabinet. Furthermore, in some embodiments of a shielded bundled cable of the present invention, see Figure 3 As shown, there are two male connector shells 1, which are respectively arranged at both ends of the insulating sheath 5. That is, in this embodiment, male connector shells 1 are arranged at both ends of the bundled cable, so that double-end grounding of the shielding layer is achieved, ensuring the transmission performance of the system in an environment with electromagnetic interference.

[0036] Specifically, in some specific examples of a shielded bundled cable of the present invention, continue to refer to Figure 2 As shown, the male shell 1 is a rectangular shell, and a plurality of male connection terminals 2 are distributed on the rectangular shell. The plurality of male connection terminals 2 are arranged in two rows along the direction from the top end to the bottom end of the rectangular shell. The two ends of the insulating sheath 5 are respectively inserted into the two top ends of the rectangular shell. The plurality of wiring cables 6 in the insulating sheath 5 are connected one-to-one with the plurality of male connection terminals 2 near the top end of the rectangular shell in turn; the shielded cables constituting the shielding net 7 are connected to one of the male connection terminals 2 near the bottom end of the rectangular shell; and the four corners of the rectangular shell are respectively provided with mounting holes for connecting to the cabinet.

[0037] On the other hand, the present invention also provides a signal room grounding cabinet, which, in some specific embodiments, includes a cabinet body, a transmission channel lightning protection copper busbar is reserved in the cabinet body, and a female connector shell 3 of any one of the above-mentioned embodiments is detachably provided on the cabinet body. Among the multiple female connector terminals 4 on the female connector shell 3, one female connector terminal 4 is connected to the transmission channel lightning protection copper busbar, and the remaining female connector terminals 4 are respectively connected one-to-one to each component to be wired and connected in the cabinet body.

[0038] It can be understood that in this embodiment, the signal room grounding cabinet can be an integrated cabinet or a frequency shifting cabinet in the railway signal room. The rest of the structure of the integrated cabinet or the frequency shifting cabinet is an existing structure and will not be described in detail here. This embodiment only explains its grounding method. Specifically, a lightning protection copper busbar for the transmission channel is reserved in the vertical slot of the integrated cabinet and the frequency shifting cabinet. A female housing 3 is fixed to the cabinet body by bolt connectors. A plurality of female connection terminals 4 are arranged on the female housing 3. Taking a 28-bit visual connector as an example, 28 female connection terminals 4 are arranged on the female housing 3, 27 of which can be used to connect the 27 components to be wired and connected in the cabinet body to form an integrated terminal of the 27 components. The remaining last female connection terminal 4 is connected to the transmission channel lightning protection copper busbar reserved in the cabinet through a yellow-green ground wire. When making wiring connections, the male shell 1 of the shielded bundled cable is also provided with 28 male connection terminals 2, 27 of which are matched and connected with the female connection terminals 4 of 27 components, and the last male connection terminal 2 is connected with the female connection terminal 4 connected to the lightning protection copper busbar. Specifically, after the bundled cable is manufactured, a 2-3 cm shielding net is left at the end, and the shielding net is connected to the male connection terminal 2 inside the male shell 1 through a yellow-green ground wire after being ring-welded at the end. The male connection terminal 2 at the 28th position of the male shell 1 indicates the grounding lead-out position of the shielding wire, and the female connection terminal 4 at the 28th position of the female shell 3 on the cabinet is connected to the transmission channel lightning protection copper busbar reserved in the cabinet through a yellow-green ground wire. The male connection terminal 2 at the 28th position of the male shell 1 and the female connection terminal 4 at the 28th position of the female shell 3 are plugged in to meet the grounding requirements of the shielded bundled cable.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
