[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, an integrated wiring seat includes a base 6, a plurality of partitions 5 and a plurality of wiring units. The plurality of partitions 5 and the plurality of wiring units are arranged alternately in sequence along the base, so that any two adjacent wiring units are separated by a partition 5, and the partition 5 can be removed. The base 6 is formed by sheet metal, and a rectangular protruding structure 6-1 is provided in the middle thereof; the rectangular protruding structure 6-1 forms a corresponding rectangular groove on the bottom surface of the base 6. The middle part of the bottom surface of the partition 5 and the wiring unit is provided with a positioning groove that matches the rectangular protruding structure 6-1 on the base 6. The positioning grooves on the partition 5 and the wiring unit cooperate with the rectangular protruding structure 6-1 on the base to realize the rapid positioning of the partition 5 and the wiring unit on the base.

[0025] The wiring unit includes a wiring screw 1, a copper connecting plate 2, a connecting seat 3 and a mounting screw 4. A positioning groove on the wiring unit is set at the bottom of the connecting seat 3. Two first mounting holes are provided at the bottom of the connecting seat 3. The mounting screw 4 is embedded and fixed in the two first mounting holes. Two second mounting holes are provided at the bottom of the connecting seat 3. The wiring screw 1 is embedded and fixed in the two first mounting holes. The mounting screw 4 is used for fixed connection with the base. The wiring screw 1 is used to connect the terminal 7 at the end of the cable. Two through holes are provided on the copper connecting plate 2. The two through holes on the copper connecting plate 2 pass through the two wiring screws 1 respectively; the two wiring screws 1 are conducted (ie electrically connected) through the copper connecting plate 2; the copper connecting plate 2 is fixed to the top surface of the connecting seat 3. Two terminal heads 7 can be installed on the same wiring screw 1, so that the wiring screw 1 can be used to achieve the one-to-two wiring requirement. Terminal head 7

[0026] Both sides of the bottom surface of the connecting seat 3 are provided with a snap-in groove 3-1; one side or both sides of the bottom of the partition 5 are provided with a snap-in hook 5-1; the snap-in hook 5-1 includes a transverse section and a vertical hook portion. The vertical hook portion can extend into the snap-in groove 3-1 of the connecting seat 3 to realize the connection between the connecting seat 3 and the partition 5. The snap-in hook 5-1 on the partition 5 hooks the snap-in groove 3-1 of the connecting seat 3 in the adjacent wiring unit. When the connecting seat 3 and the base 6 are fixed by bolts, the snap-in hook 5-1 on the partition 5 is clamped by the connecting seat 3 and the base 6, and the structure is stable; when the partition 5 needs to be removed, it is only necessary to remove the bolts between the connecting seat 3 and the base 6 and take out the connecting seat 3, and the partition 5 can be easily removed; thereafter, the connecting seat 3 is reinstalled on the base 6, so that there is no obstruction between the two adjacent wiring units.

[0027] The arrangement direction of the two wiring screws 1 is perpendicular to the arrangement direction of each wiring unit. The arrangement direction of the two mounting screws 4 is perpendicular to the arrangement direction of each wiring unit. Thus, the width of the wiring unit can be reduced while meeting the diameter requirement of the wiring cable.

[0028] In this embodiment, the width of the connection seat 3 is designed to be 27 mm, taking into account the specifications of commonly used terminals and cables, and can meet the requirements of 120 mm. 2 The following cable usage requirements, some brands can meet 150mm 2 The following cables have a wide range of application requirements.

[0029] The four corners of the base are provided with mounting through holes; the base is fixed on the vehicle end box of the train through the mounting through holes and bolts.

[0030] The partition 5 is made of insulating material, and PA66 (polyhexamethylene adipamide, commonly known as nylon-66) is preferred in this embodiment. It has good insulation performance and its main function is to increase the creepage distance and electrical clearance, which can ensure that the electrical performance between two adjacent terminal blocks is not affected by each other; the wiring screws 2 and the copper connecting plate 2 are both made of nickel-plated copper; when wiring, the current conduction and diversion functions can be realized.

[0031] Since the partition 5 is easy to disassemble, the two wiring units can be directly adjacent to each other by removing part of the partition 5, and then the two wiring units can be used in conjunction with each other by using a copper connecting plate, thereby improving the flexibility of the integrated wiring socket provided in this embodiment.

[0032] The working principle of the utility model is as follows:

[0033] A wiring unit that is snapped together with the partition 5 is installed on the base 6, and the connecting seat 3 of the wiring unit is fixed to the base 6 by installing screws 4; then, the cables are connected to the wiring screws 1 of the wiring unit to complete the wiring work; the screw fastening method used in this embodiment has a simple structure and high reliability, can be applied to various harsh environments, and ensures that the wiring seat does not fall off the base.
