[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0019] See also Figure 1-Figure 3As shown, a socket-type terminal rack for inverted connection of existing signal transformation cables includes two parallel bottom beams 1, the two bottom beams 1 are arranged on the same horizontal plane, a vertical beam 2 is fixedly connected at the same position on the top of each bottom beam 1, two parallel horizontal beams 3 are fixedly connected between the two vertical beams 2, and a reinforcing beam is also fixedly connected between the two vertical beams 2, and the reinforcing beam is located below the two horizontal beams 3; a terminal mounting plate 4 is fixedly connected between the two horizontal beams 3, and a plurality of socket terminals 5 are detachably mounted on the terminal mounting plate 4; when in use, the signal cable is connected to the socket terminal 5, so that when using the socket terminal rack of the present application, repeated connection, welding and removal of the inverted signal cable can be avoided. In addition, the detachable socket terminal 5 can be easily replaced and increased or decreased, and can also provide better protection for the correctness of wiring during inverted connection, accelerate the inverted connection speed, improve construction efficiency and safety.

[0020] Specifically, the installation structure of the socket terminal 5 is as follows: a rectangular through groove 6 is provided on the terminal mounting plate 4, and positioning grooves 7 are provided at the top and bottom of the rectangular through groove 6. The top and bottom of each socket terminal 5 are inserted in the positioning groove 7, and the socket terminal 5 is fixed to the terminal mounting plate 4 by screws; when installing the socket terminal 5, first insert the socket terminal 5 into the positioning grooves 7 on the upper and lower sides of the rectangular through groove 6 to achieve preliminary positioning of the socket terminal 5, and then use screws to fix the socket terminal 5 to the terminal mounting plate 4.

[0021] In order to facilitate the movement of the socket-type terminal tray rack, universal wheels 8 are fixedly connected to both sides of the bottom of each bottom beam 1 .

[0022] When the socket-type terminal disk rack is moved to the specified position, it is necessary to prevent the socket-type terminal disk rack from sliding on the ground. For this purpose, a supporting structure is arranged on the bottom beam 1. The supporting structure is specifically as follows: a push rod 9 is penetrated and slidably connected on each bottom beam 1, and a support plate 10 is fixedly connected to the bottom end of the push rod 9; a push plate 11 is fixedly connected to the top end of the push rod 9, and a card slot 12 for inserting the push plate 11 is opened on the side wall of each vertical beam 2; when in use, the push rod 9 is first pushed downward so that the bottom of the support plate 10 contacts the ground, and the push plate 11 is rotated at the same time, so that the push rod 9 also rotates, and the push plate 11 is inserted into the card slot 12, thereby determining the height of the push plate 11, and at this time, the support plate 10 is also in contact with the ground, thereby supporting the bottom beam 1, and due to the friction between the support plate 10 and the ground, the rotation of the universal wheel 8 cannot drive the socket-type terminal disk rack to move on the ground, and finally the socket-type terminal disk rack will not move easily on the ground.

[0023] In order to increase the friction between the support plate 10 and the ground, reduce the wear on the support plate 10 itself, and extend the service life of the support plate 10, a wear-resistant layer is provided at the bottom of the support plate 10;

[0024] The wear-resistant layer is made of wear-resistant materials, and the wear-resistant materials may be: alloy steel, cast iron, wear-resistant ceramics, wear-resistant polymers, and wear-resistant synthetic materials.

[0025] Among them, wear-resistant polymers refer to polymer materials such as polyethylene, polypropylene, and polyurethane, which can improve wear resistance by adding fillers or modification;

[0026] Among them, wear-resistant synthetic materials include carbon fiber composites, glass fiber composites, etc., which have high wear resistance.

[0027] When the utility model is used, before construction, several socket-type terminal racks for cable inversion are made according to the technical solution according to the site requirements, and the racks are placed at the corresponding positions. According to the inversion wiring diagram, the signal cables to be inverted are sequentially connected to the socket terminals 5, and well marked. After the cable connection is completed, the wiring diagram is compared again to check whether the wiring of each terminal is correct and whether the markings are complete. Check that the cable connection wiring is firm and not loose. After all the cable connections are completed correctly, start the debugging work;

[0028] The socket terminal 5 reel for existing signal transformation and inversion proposed in this application can avoid repeated connection, welding and removal of inversion signal cables, and can provide better protection for the correctness of wiring during inversion, speed up the inversion speed, improve construction efficiency and safety. Due to the use of detachable socket terminals 5, construction operators can easily remove, replace and increase or decrease socket terminals 5. The reel has a wide range of application prospects and can be widely used in railway signal electrical equipment for transition transformation of existing signals and other electrical industry fields.
