Technical Field

[0001] This application relates to the field of magnetic terminal technology, and in particular to a double-row column-type bent six-column magnetic terminal and its manufacturing mold. Background Technology

[0002] Safety is an eternal theme in railway transportation. In the operation of railway lines, ensuring railway traffic safety is paramount, especially the safety of the electrical control and turnout interlocking equipment. Currently, the traditional HZ24 series cable boxes used for turnout electric switch machines have several shortcomings. First, the traditional HZ24 series cable boxes use a conventional magnetic terminal structure, which is not sufficiently robust in terms of error prevention technology for turnout electric switch machine wiring. There are defects in the connection of cable cores and external wiring of the electric switch machine. During signal engineering construction, maintenance, and fault handling, frequent disconnection or interruption of the cable cores and external wiring of the electric switch machine can easily lead to incorrect connections, resulting in turnout control and indication circuit malfunctions. Improper handling can easily trigger traffic safety accidents.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Summary of the Invention

[0022] The present application will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0023] According to specific embodiments of this application, such as Figure 1-4 As shown, this application provides a double-row column-type bent six-column magnetic terminal, the magnetic terminal comprising: The substrate 1 has a row of inner holes and a row of outer holes arranged side by side.

[0024] An inner chord terminal 11 is fixed in each inner hole on the base 1. The inner chord terminal 11 is used to connect the core wire in the main control cable and the core wire in the branch cable.

[0025] An outer chord terminal 12 is fixed in each outer hole on the base 1. The outer chord terminal 12 is used to connect the core wire in the secondary cable and the core wire in the connecting cable.

[0026] Electrical connector 14, in which the inner chord terminal 11 and the outer chord terminal 12 that are adjacent in the radial direction are electrically connected by an electrical connector 14.

[0027] The double-row column-type bent six-column magnetic terminal is installed in the cable box. The main control cable (X1) from the signal tower or the previous electric switch machine is introduced into the cable box, and the core wire of the main control cable is connected to the inner chord terminal 11. The branch cables (X2-X5) from the signal tower or the previous electric switch machine are introduced into the cable box, and the core wire of the branch cables is connected to the inner chord terminal 11. The auxiliary cable led out from the cable box is used to electrically connect to the next electric switch machine, and the core wire of the auxiliary cable is connected to the outer chord terminal 12. The connecting cable led out from the cable box is used to electrically connect to the electric switch machine near the cable box, and the core wire of the connecting cable is connected to the outer chord terminal 12.

[0028] In other words, in this double-row column-type bent six-column magnetic terminal, the core wires in the main control cable and branch cable are all connected to the inner chord magnetic terminal, while the core wires in the auxiliary cable and connecting cable are all connected to the outer chord magnetic terminal. This allows the cable introduced into the cable box from upstream to be connected to different magnetic terminals, and the cable led out of the cable box to the downstream. During construction operations such as checking and confirming the cable core wires and the external line of the electric switch machine, troubleshooting the turnout control and indication circuit, and tidying up the wiring inside the cable box, it is only necessary to perform construction on the core wires on the inner chord terminal 11 or the outer chord terminal 12, which greatly reduces the probability of wiring errors. This gives the double-row column-type bent six-column magnetic terminal better wiring error prevention function and helps to improve the construction efficiency of the cable box.

[0029] The bottom of the base 1 is also provided with a plurality of recesses, each of which is provided with an electrical connector 14. In this embodiment, the recesses extend radially along the base 1, and each recess is interconnected with an inner hole and an outer hole, so as to fix a radially adjacent inner chord terminal 11 and an outer chord terminal 12 in a recess, and the recesses facilitate the fixing of the electrical connector 14.

[0030] The electrical connector 14 is a copper sheet, which is placed in a groove at the bottom of the base 1. The copper sheet has through holes at the positions corresponding to the inner and outer holes on the base 1, so as to allow the inner chord terminal 11 and the outer chord terminal 12 to be connected and installed.

[0031] In this embodiment, both the inner string terminal 11 and the outer string terminal 12 are metal screws, and both the inner string terminal 11 and the outer string terminal 12 are conductive.

[0032] When installing the magnetic terminal, first install the copper sheet in the recess at the bottom of the base 1, then pass the inner chord terminal 11 through the inner hole on the copper sheet and the inner hole on the base 1, and connect a nut to the inner chord terminal 11; pass the outer chord terminal 12 through the outer hole on the copper sheet and the outer hole on the base 1, and connect a nut to the outer chord terminal 12. This completes the assembly of the magnetic terminal.

[0033] The base 1 has a fan-shaped structure. In this embodiment, the fan-shaped base 1 is disposed in the cable box, which makes it easier for the corresponding cable in the cable box to be connected to the magnetic terminal of the fan-shaped structure.

[0034] A connecting hole 13 is provided at each of the two ends of the base 1. In this embodiment, the magnetic terminal is fixed in the cable box by passing a bolt through the connecting hole 13 at both ends of the base 1.

[0035] The base 1 is provided with six inner chord terminals 11, six outer chord terminals 12, and six electrical connectors 14. In this embodiment, the magnetic terminal is a double-row column-type bent six-column magnetic terminal, and each electrical connector 14 is connected to one inner chord terminal 11 and one outer chord terminal 12 at both ends; the double-row column-type bent six-column magnetic terminal is more suitable for HZ24 series cable boxes.

[0036] This application also provides a manufacturing mold for a double-row column-type bent six-pillar magnetic terminal. The manufacturing mold is used to manufacture the substrate 1 semi-finished product of the above-mentioned double-row column-type bent six-pillar magnetic terminal. The manufacturing mold includes: The core plate 3 has multiple recessed cores 31 and multiple connecting hole cores 33. The recessed cores 31 form recesses on the substrate 1, and the connecting hole cores 33 form connecting holes 13 on the substrate 1. The cavity plate 5 has an inner cavity that forms the outer shape of the substrate 1. In this manufacturing mold, the core plate 3 and the cavity plate 5 can be used to manufacture the structure of the substrate 1.

[0037] In this embodiment, a hollow protrusion is provided on the cavity plate 5 at the position corresponding to the connecting hole core 33, and a through hole is provided in the center of the hollow protrusion. The connecting hole core 33 is inserted into the through hole of the hollow protrusion of the cavity plate 5. This arrangement can not only be used for mutual positioning of the core plate 3 and the cavity plate 5, but also form a stepped hole structure connecting hole 13.

[0038] Multiple recessed cores 31 located at the center of the core plate 3 are provided with perforations. Multiple recessed cores 31 located on the outer side of the core plate 3 are provided with two cylinders 32. The two cylinders 32 are located on the inner and outer sides of the recessed cores 31 respectively, and are used to form the inner and outer holes on the substrate 1.

[0039] In this embodiment, two cylinders 32 are provided on the core 31 to form an inner hole and an outer hole on the base 1, respectively, and the inner hole, the outer hole and the core 32 are interconnected. A through hole is provided on the cavity plate 5 corresponding to the position of the cylinder 32, so that when the core plate 3 and the cavity plate 5 are aligned, the cylinder 32 on the core plate 3 is inserted into the through hole on the cavity plate 5, so that the core plate 3 and the cavity plate 5 are mutually positioned.

[0040] The manufacturing mold also includes a positioning plate 2, which is provided with multiple positioning posts 21, and corresponding through holes are provided on the cavity plate 5. When the positioning plate 2, the core plate 3, and the cavity plate 5 are aligned, the positioning posts 21 simultaneously penetrate into the through holes of the recessed core 31 and the cavity plate 5. In this embodiment, the positioning posts 21 on the positioning plate 2 connect the center parts of the core plate 3 and the cavity plate 5, and in conjunction with the connection of the positioning structure on the outer part of the core plate 3 and the cavity plate 5, the overall manufacturing mold can be accurately positioned, thereby ensuring that the base 1 has better manufacturing quality.

[0041] The manufacturing mold also includes a backing plate 4 and an ejector pin 6. The backing plate 4 has through holes corresponding to the ejector pin 6 and the sinker core 31. The backing plate 4 is located between the core plate 3 and the cavity plate 5. The core plate 3 has through holes corresponding to the ejector pin 6. The ejector pin 6 passes through the through holes in the core plate 3 and extends into the backing plate 4.

[0042] In this embodiment, when manufacturing the substrate 1, the positioning plate 2, core plate 3, pad plate 4, and cavity plate 5 are assembled sequentially, and the ejector rod 6 extends through the perforation in the core plate 3 into the pad plate 4. At this time, the ejector rod 6 and the lower surface of the pad plate 4 are flush with each other. An injection port is provided on the core plate 3 or the cavity plate 5. The manufacturing material is pressed into the manufacturing mold through the injection port to form the shape of the substrate 1. After the substrate 1 is formed, the cavity plate 5 is moved backward to separate the core plate 3 from the cavity plate 5. At this time, the ejector rod 6 pushes downward, so that the formed substrate 1 can be ejected from the core plate 3 through the ejector rod 6, thus completing the manufacturing process of the semi-finished substrate 1.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
