Description

Technical Field

[0001] The invention belongs to the field of railway vehicle wiring, and in particular relates to a wiring positioning device for terminal blocks. Background Art

[0002] Terminal blocks are widely used in railway vehicles. The wiring of terminal blocks has the characteristics of many wire harnesses and dense wiring positions. In order to achieve the purpose of neat wire harnesses, the reserved lengths of the wires at the horizontal wiring positions should be different according to the distances of the wiring positions. At present, there are two problems in pure manual wiring. One is that the wires in the horizontal row adopt the same length. After the wires are inserted, the appearance is messy, the wiring is not standardized, and it also affects the later line search. The other is that the number of turns of the wire harness branching into the terminal block is small, resulting in a large span of the wires at the longitudinal positions, which also affects the later appearance quality. If the method of measuring the length one by one with a tape measure is used to solve the above problems, it is time-consuming and laborious. Therefore, an invention of a wiring positioning device for terminal blocks can accurately position the wires in a time-saving and labor-saving manner. Summary of the Invention

[0003] In view of this, the present invention aims to provide a wiring positioning device for terminal blocks, which can accurately position the wires, save time and effort, and improve work efficiency.

[0004] To achieve the above object, the technical solution of the present invention is realized as follows:

[0005] A wiring positioning device for terminal blocks includes a guide rail, a positioning scale, wire clamps, and knurled screws. A chute is provided on the upper surface of the guide rail. A slider is provided at the bottom of the positioning scale, and the slider is slidably connected to the chute to realize the movable connection between the positioning scale and the guide rail. The positioning scale is provided with knurled screws, and the knurled screws pass through the bottom of the positioning scale to realize the fixed connection between the positioning scale and the guide rail. A plurality of guide rail wire clamps are provided on one side of the guide rail, and a positioning wire clamp is provided on one side of the positioning scale. The positions of the positioning wire clamp and the guide rail wire clamps correspond to each other.

[0006] Further, the cross-section of the guide rail is L-shaped, including a horizontal plate and a vertical plate. One side of the horizontal plate is fixedly connected to one side of the vertical plate to form an integral structure. A chute is provided on the upper surface of the horizontal plate, and a plurality of guide rail wire clamps are provided on one side of the vertical plate.

[0007] Further, the cross-section of the chute is trapezoidal, and the shape of the slider corresponds to that of the chute.

[0008] Further, the number of the guide rail wire clamps is 10.

[0009] Further, the guide rail wire clamps and the positioning wire clamps have the same structure, including a first clamping plate, a second clamping plate, and a connecting plate. One side of the bottom of the first clamping plate is fixedly connected to one side of the bottom of the second clamping plate through the connecting plate. The middle parts of the first clamping plate and the second clamping plate are both arc-shaped structures protruding outward.

[0010] Further, the positioning scale includes a bottom plate, a support plate, a rectangular scale, and a bent plate. One end of the bottom plate is fixedly connected to one end of the support plate. The bottom plate and the support plate are perpendicular to each other. The upper end of the support plate is fixedly connected to the rectangular scale. The rectangular scale is parallel to the bottom plate. A bent plate is fixedly installed on the inner wall of the rectangular scale, and one end of the bent plate is fixedly connected to the inner wall of the support plate.

[0011] Further, the cross-section of the bent plate is in a semi-circular structure.

[0012] Further, scale lines are provided on the upper surface of the rectangular scale.

[0013] Compared with the prior art, the terminal block wiring positioning device of the present invention has the following advantages:

[0014] (1) For the terminal block wiring positioning device of the present invention, the semi-circular bent plate in the positioning scale structure is used to define the bending radius of the wire, so that after the entire terminal block wiring is completed, the bending radius of the wire is uniform.

[0015] (2) For the terminal block wiring positioning device of the present invention, the rectangular scale is provided with scales and wiring position markings. The wiring position markings can quickly locate the reserved length, and the scales can be used to expand the function for quickly measuring the length, which is more accurate and faster than a tape measure.
