Detailed Description

The invention discloses a wiring device which is beneficial to plugging and unplugging of cables, so that debugging and maintenance of equipment are facilitated. The invention also discloses a magnetic suspension vehicle.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 and 2, the present invention discloses a wiring device, which includes a panel 1, wherein the panel 1 can be connected to a board 9 of a magnetic levitation train, a wire passing hole 10 is disposed at a position of the board 9 opposite to the panel 1, and the wire passing hole 10 is used for communicating a lower portion of the board 9 with the panel 1. The panel 1 is provided with a mounting portion for mounting a connector. The cable below the sweep 9 and the cable above the sweep 9 are plugged together by connectors.

When the device is debugged and overhauled, the cable above the vehicle plate 9 or the cable below the vehicle plate 9 is pulled out of the connector, then the cable above the vehicle plate 9 and the cable below the vehicle plate 9 are disconnected, and after the debugging and overhauling are finished, the cable above the vehicle plate 9 or the cable below the vehicle plate 9 is inserted into the connector again, so that the connection between the cable above the vehicle plate and the cable below the vehicle plate 9 can be realized. The arrangement of the wiring device in the invention can quickly disconnect or connect the cables above the sweep 9 and the cables below the sweep 9, thereby being beneficial to debugging and overhauling of equipment.

In the embodiment of the present invention, the mounting portion of the panel 1 for mounting the connector is a connector insertion hole 111, and the connector insertion hole 111 is used for inserting the connector. The panel 1 is provided with a plurality of connector jacks 111, and each connector jack 111 is used for plugging a connector. So can change interconnecting link very conveniently when debugging and overhauing equipment. For example, initially, the first cable below the bed 9 and the first cable above the bed 9 are plugged into a passage through the first connector, and when a connection line is exchanged, the first cable below the bed 9 can be unplugged from the first connector, and then the first cable below the bed 9 is plugged into the second connector, which is connected with the second cable above the bed 9, so that the first cable below the bed 9 and the second cable above the bed 9 are conducted, and the exchange of the connection line is realized.

The cables below the bed 9 are typically routed in a horizontal plane below the bed 9 and if the cables below the bed 9 are connected to connectors in the panel 1 above the bed 9, the cables need to be bent upwards. The applicant has noticed that the thickness of the panel 9 is limited, resulting in a small height of the wire passing hole 10, in which case the cable under the panel 9 would need to be bent more significantly if it were to be connected to the connector of the panel 1, which would lead to cable breakage. In order to avoid the cable under the vehicle plate 9 from being bent obviously, the invention is provided with the box body 2, the box body 2 is arranged around the wire through hole 10, the box body 2 is communicated with the wire through hole 10, and the panel 1 is arranged and connected at the top of the box body 2. The box body 2 has a predetermined height, and the box body 2 is attached to the floor panel 9. Referring to fig. 2, the inner cavity of the box body 2 can be regarded as an upward extension of the wire passing hole 10 of the vehicle panel 9, which is equivalent to heightening the wire passing hole 10. Therefore, the cable below the vehicle plate 9 can be slightly bent in the wire through hole 10 and the box body 2 and connected to the connector on the panel 1, and the service life of the cable is prolonged.

In order to facilitate wiring, the wiring device is arranged below the electrical cabinet in the vehicle. The predetermined height of the cabinet 2 is therefore determined by the distance between the sweep 9 and the electrical cabinet and the degree of bending of the cable below the sweep 9. The distance of the face plate 1 of the wiring device from the bottom of the electrical cabinet cannot be too small, otherwise the cables above the carriage plate 9 can be bent significantly at the face plate 1. The distance of the junction device panel 1 from the electrical bottom cannot be too large, otherwise the height of the box body 2 would be small, and thus the bending of the cable below the sweep 9 cannot be effectively relieved.

The bottom of the electrical cabinet is usually provided with a convex beam protruding downwards, the existence of the convex beam can cause the distance between the convex beam and the panel 1 to be small, if the cable above the vehicle plate 9 is plugged into the connector below the convex beam, the cable needs to be bent obviously, and therefore, the area of the panel 1 opposite to the convex beam is not suitable for plugging the cable.

In order to avoid that the operator unknowingly plugs the cables into the area of the panel 1 corresponding to the protruding beams, the invention provides that the panel 1 comprises a light panel 12 and a perforated plate 11. Connector jacks 111 for connector insertion are arranged on the hole plate 11, the connector jacks 111 are not provided on the optical plate 12, and the optical plate 12 corresponds to the convex beams. After the wiring device is installed under the electrical cabinet, the convex beam faces the light panel 12.

The optical plate 12 and the aperture plate 11 are separately processed for convenience of processing, and then the optical plate 12 is fastened to the edge of the aperture plate 11 by a screw. Referring to fig. 1, the well plate 11 includes a first well plate 11 and a second well plate 11. The first orifice plate 11 and the second orifice plate 11 are respectively arranged at two sides of the optical plate 12, and two side edges of the optical plate 12 are overlapped and locked at the edges of the first orifice plate 11 and the second orifice plate 11 through screws.

The connector of the present invention includes a first connector and a second connector. The first connector includes a first plug hole portion 7 and a first socket portion 6 arranged along an axial direction of the first connector. A first plug hole is provided in the first plug hole portion 7. The outer diameter of the first plug hole portion 7 is smaller than the diameter of the connector insertion hole 111, so that the first plug hole can penetrate the connector insertion hole 111. The outer diameter of the first socket part 6 is larger than the diameter of the connector insertion hole 111, and the hole edge of the connector insertion hole 111 forms a barrier to the first socket part 6, thereby preventing the first connector from falling through the connector insertion hole 111. The end of the cable located below the sweep 9 is connected with a first plug, the first plug is matched with the first plug hole, the first plug can be plugged into the first plug hole portion 7, and the end of the cable located above the sweep 9 is in crimping connection with the first socket portion 6.

In this embodiment, when connecting or disconnecting the cable, the panel 1 is detached from the housing 2, the first connector to which the cable above the floor 9 is connected is inserted into one connector insertion hole 111, the first plug of the cable below the floor 9 is inserted into the first plug hole portion 7 of the first connector or pulled out from the first plug hole portion 7, and after the insertion is completed, the panel 1 is locked to the housing 2. The first connector is stably held in the corresponding connector insertion hole 111 by its own weight and the weight of the cable under the floor 9.

The connection mode of the panel 1 and the box body 2 can be screw connection or clamping connection. If the panel 1 needs to be removed when the cables are attached and detached, the panel 1 is arranged to be snapped into the cassette 2. Specifically, a snap hole is provided on the upper end surface of the case 2, a snap is provided on the surface of the panel 1 facing the case 2, and the snap is snapped into the snap hole when the panel 1 is pressed onto the case 2. When the panel 1 is detached from the case 2, the catch contracts and exits from the catch hole.

The second connector includes a second plug hole portion and a second socket portion arranged along an axial direction of the second connector. The outer diameter of the second socket portion is smaller than the diameter of the connector insertion hole 111, so that the second socket portion can penetrate the connector insertion hole 111. The outer diameter of the second plug hole portion is larger than the diameter of the connector insertion hole 111, and the hole edge of the connector insertion hole 111 forms a blocking effect on the second plug hole portion, preventing the second connector from falling from the connector insertion hole 111. The end of the cable below the sweep 9 is connected in the second socket portion, and the end of the cable above the sweep 9 is connected with a second plug which can be plugged in the second plug hole portion.

In this embodiment, the disconnection between the cable above the deck 9 and the corresponding cable below the deck 9 can be achieved by simply pulling out the second plug of the cable above the deck 9 from the second plug hole portion of the second connector without attaching or detaching the panel 1. The second insertion of the cable above the floor 9 into the second plug hole of the second connector can achieve the conduction between the cable above the floor 9 and the corresponding cable below the floor 9.
