The structure, connection relationship, and function of each component are as follows:

[0023] The mounting block 1 serves as the basic support component of the device. One side of it has a single-sided open, unidirectional limiting groove 101. The limiting groove 101 provides installation and movement space for the fixed-end positioning comb 2, the free-end positioning comb 4, and the connector to be assembled, ensuring that each component moves along a preset direction and preventing lateral displacement. The bottom of the mounting block 1 has two mounting holes 102, which correspond one-to-one with the threaded holes 202 of the fixed-end positioning comb 2, allowing for the detachable fixing of the fixed-end positioning comb 2 using screws 5. The openings of the mounting holes 102 are chamfered 103, facilitating quick insertion of the screws 5 and reducing assembly alignment difficulty, while also preventing sharp edges from scratching operators or damaging assembly tools. To balance support strength and lightweight requirements, the mounting block 1 is made of POM (polyoxymethylene) engineering plastic. This material has excellent rigidity, wear resistance, and impact resistance, and is lightweight, making it easy for operators to handle and use.

[0024] The fixed end positioning comb 2 is made of high-speed steel material, high-speed steel has high hardness HRC60 or above, high wear resistance and good toughness, can withstand long-term extrusion and friction of the pin without easy wear or deformation, ensure the positioning accuracy after long-term use. The top side of the fixed end positioning comb 2 is provided with equidistantly arranged first pin positioning combing grooves 201, the groove width is usually 0.05-0.1mm larger than the diameter of the connector pin to be combed, which can ensure that the pin can be smoothly put into the groove, and can also avoid the pin from shaking in the groove; the groove depth is not less than 1 / 2 of the pin diameter, which can ensure that the pin will not come out of the groove after being put in. The bottom of the fixed end positioning comb 2 is provided with two screw holes 202 symmetrically distributed along the length direction, the screw holes 202 are matched with the screws 5, the screws 5 pass through the mounting holes 102 of the mounting block 1 and are connected with the screw holes 202, which can firmly fix the fixed end positioning comb 2 in the limiting groove 101 of the mounting block 1, and provide stable reference support for pin combing.

[0025] The free end positioning comb 4 is also made of high-speed steel material, the top side is provided with second pin positioning combing grooves 401 with the same specifications as the fixed end positioning comb 2, and the combing groove opening direction is consistent with the fixed end positioning comb 2; the length, width and thickness of the free end positioning comb 4 are the same as those of the fixed end positioning comb 2, and the length and width of the free end positioning comb 4 are the same as those of the limiting groove 101 of the mounting block 1. The free end positioning comb 4 does not need to be fixed, and is directly placed in the limiting groove 101 of the mounting block 1, and can slide freely along the length direction of the limiting groove 101, so as to adjust the distance between the free end positioning comb 4 and the fixed end positioning comb 2, and adapt to the combing requirements of connector pins with different length specifications.

[0026] The isolation sheet 3 is used as a protection and positioning component during pin combing, and is made of high-speed steel material to avoid deformation or wear after long-term use. The isolation sheet 3 is a single plate structure, and its thickness is equal to the theoretical distance between the two rows of pins to be combed. When the isolation sheet 3 is placed between the two rows of pins, the distance between the two rows of pins can be strictly limited to prevent the pins from deforming towards the middle during combing due to extrusion; the length of the isolation sheet 3 is not less than the arrangement length of the pins to be combed, and the width is not less than the length of the pins to be combed, so as to completely cover the contact area of the two rows of pins and achieve comprehensive protection. One side of the isolation sheet 3 is provided with a round corner 301 with a radius of 0.5-1.5mm, and the edge is polished to have a surface roughness Ra0.8μm or below, which can avoid scratching the plating layer or insulating layer of the pins when the isolation sheet 3 is placed between the two rows of pins, and reduce the resistance during insertion, so as to facilitate quick placement and removal.

[0027] The screw 5 is a countersunk screw, the rod diameter of the screw 5 is matched with the installation hole 102 of the mounting block 1, the hole diameter of the installation hole 102 is 0.1-0.2mm larger than the rod diameter, which facilitates the screw 5 to be quickly inserted, and the thread specification is matched with the threaded hole 202 of the fixed end positioning comb 2; the head diameter of the screw 5 is matched with the diameter of the countersunk hole of the installation hole 102 of the mounting block 1, so that the head of the screw 5 can be completely embedded in the installation hole 102 after being tightened, and does not protrude from the bottom surface of the mounting block 1, thereby avoiding the device from being unstable due to the protruding head when the mounting block 1 is placed.

[0028] The detachable connection design of the fixed end positioning comb 2 and the mounting block 1 facilitates the later maintenance or replacement of different specifications of the positioning comb, such as replacing the positioning comb with different combing groove spacings to adapt to connectors with different pin spacings; the slidable design of the free end positioning comb 4 enables the device to have a certain universality and adapt to various specifications of connector pin combing within the range of the limiting groove 101.

[0029] In the installation process, the fixed end positioning comb 2 is placed into the limiting groove 101 of the mounting block 1, the position is adjusted to make the threaded hole 202 of the fixed end positioning comb 2 completely aligned with the installation hole 102 of the mounting block 1, and the first pin positioning combing groove 201 of the fixed end positioning comb 2 is ensured to be open towards the open side of the limiting groove 101.

[0031] The free end positioning comb 4 is placed into the limiting groove 101 of the mounting block 1, the second pin positioning combing groove 401 of the free end positioning comb 4 is open towards the same direction as the fixed end positioning comb 2, and the free end positioning comb 4 is pushed to confirm that it can smoothly slide along the length direction of the limiting groove 101 without jamming, and the overall assembly of the device is completed.

[0032] The operator holds the electrical connector 6, confirms that the contact pins 601 are not obviously broken or deformed, and then places the main body of the electrical connector 6 into the limiting groove 101 of the mounting block 1, so that the contact pins 601 are upward and the electrical connector 6 is located between the fixed end positioning comb 2 and the free end positioning comb 4.

[0033] The position of the electrical connector 6 is slightly adjusted to ensure that the two rows of contact pins 601 are both located directly above the pin positioning combing grooves of the fixed end positioning comb 2 and the free end positioning comb 4 without obvious deviation.

[0034] Take the isolation sheet 3, hand holding isolation sheet 3 no rounded side, with rounded 301 side towards the contact pin 601 of the electrical connector 6, slowly insert the isolation sheet 3 between the two rows of pins, until the bottom surface of the isolation sheet 3 and the limit groove 101 bottom surface of the installation block 1 fit, at this time the isolation sheet 3 will separate the two rows of pins, avoid extrusion during combing process.

[0035] One hand holds the electrical connector 6, the other hand slowly moves the electrical connector 6, so that the pins on one side close to the fixed end positioning comb 2 fall into the first pin positioning combing groove 201 of the fixed end positioning comb 2 one by one, and the electrical connector 6 is stopped after confirming that all the pins on the row are completely in the combing groove.

[0036] One hand holds the electrical connector 6, the other hand pushes the free end positioning comb 4 to slide towards the electrical connector 6, so that the pins on one side close to the free end positioning comb 4 fall into the second pin positioning combing groove 401 of the free end positioning comb 4 one by one, and the electrical connector 6 is stopped after confirming that all the pins on the row are completely in the combing groove.
