Description

Technical Field

[0001] This utility model belongs to the field of electrical assembly technology and relates to a pin combing tool for through-hole connectors. Background Technology

[0002] In the connector assembly process of electrical assembly manufacturing, due to the large number, fine density, and movable pins of through-hole connectors, the installation requirements for through-hole connectors are becoming increasingly stringent to ensure a high connector assembly pass rate. Currently, the connector assembly process faces the following problems:

[0003] 1. Through-hole connectors have a large number of pins, fine pins, and movable pins, making it difficult to insert them into the corresponding mounting holes on the printed circuit board. This makes assembly difficult and installation inefficient, thereby reducing the product qualification rate and increasing labor costs.

[0004] 2. During the installation of through-hole connectors, the device pins may deform, be damaged, or even break, resulting in device loss and wasting a lot of costs.

[0005] 3. During installation, multiple pins of the through-hole connector may damage the mounting holes of the printed circuit board, rendering the printed circuit board unusable and wasting a lot of costs. Utility Model Content

[0006] To address the technical problems of difficult installation, low efficiency, low pass rate, and high cost when mounting through-hole connectors onto printed circuit boards due to the large number, fineness, and mobility of their pins, this utility model discloses a pin combing fixture for through-hole connectors. The pin combing fixture includes a hand-held part, a combing part, and a tooth pitch adjustment structure.

[0013] Furthermore, the slot is a through slot provided on the first comb tooth, and the second comb tooth moves in the through slot of the first comb tooth in the direction of the previous first comb tooth or the next first comb tooth.

[0014] In another optional configuration of the tooth spacing adjustment structure, the surface of the handheld part is provided with a sliding groove parallel to the combing part, the adjustment ruler is located outside the handheld part and fixed in the sliding groove by the locking member, and each second comb tooth contacts the surface of one of the first comb teeth respectively.

[0015] Furthermore, the free ends of both the first and second comb teeth are tapered, and the surfaces of both the first and second comb teeth are smooth planes.

[0016] Furthermore, both the first and second comb teeth have an antistatic layer on their surfaces.

[0017] Furthermore, the adjustment ruler is provided with a scale.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: The pin combing tool of this utility model is a major innovative breakthrough in improving the production capacity of electrical assembly. It simplifies the process, reduces costs, and can be widely promoted and used. The distance between the comb teeth can be adjusted by the tooth pitch adjustment structure, so that it can be used for pins with different pitches on different through-hole connectors. At the same time, the use of the pin combing tool can also avoid connector pin deformation, reduce damage to printed circuit board mounting holes, improve production consistency, and improve production efficiency. It has social value for widespread application. Attached Figure Description

[0027] It should also be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this disclosure. The illustrations only show the components related to this disclosure and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0028] This utility model discloses a pin combing tool for a through-hole connector, see [link to relevant documentation]. Figure 1 As shown, the pin combing fixture includes a handheld part 1, a combing part, and a tooth pitch adjustment structure 3. One end of the handheld part 1 is provided with a combing part. The handheld part and the combing part can be designed as an integral unit. The combing part includes a plurality of first comb teeth 2 arranged at equal intervals. The tooth pitch adjustment structure 3 is provided on the handheld part 1.

[0029] See Figure 2 As shown, the tooth spacing adjustment structure 3 includes an adjustment ruler 31, on which second comb teeth 32 corresponding to each of the first comb teeth 2 are provided at equal intervals, and the distance between adjacent second comb teeth 32 is greater than the distance between adjacent first comb teeth 2.

[0030] By adjusting the horizontal position of the tooth spacing adjustment structure 3 on the handheld part 1, the distance between the comb teeth after adjustment is made greater than the pin diameter and less than the sum of the pin diameter and the pin spacing. Specifically, when the adjustment ruler 31 moves to the left, the second comb tooth 32 corresponding to the first comb tooth 2 moves towards the previous first comb tooth 2, and the distance between the second comb tooth 32 of the previous first comb tooth 2 and the next first comb tooth 2 decreases; when it moves to the right, the second comb tooth 32 corresponding to the first comb tooth 2 moves towards the next first comb tooth 2, and the distance between the second comb tooth 32 of the previous first comb tooth 2 and the next first comb tooth 2 decreases. At the same time, the second comb tooth 32 and the first comb tooth 2 can be set according to the pin diameter and the spacing between the two pins to ensure that there is only one row or column of pins between the comb teeth after the tooth spacing adjustment.

[0031] The pin combing tool of this utility model is used to comb multiple pins arranged in an array on a through-hole connector. Since the distance between adjacent first comb teeth 2 is fixed, the horizontal position of the tooth spacing adjustment structure 3 on the handheld part 1 can be adjusted according to the distance between each row or column of pins and the distance between the pins, so that the position of the second comb teeth 32 relative to the first comb teeth 2 changes, thereby making the distance between the adjusted comb teeth meet the requirements for insertion between two adjacent rows or columns of pins.

[0032] Furthermore, the tooth pitch adjustment structure 3 also includes a locking member 33, which locks and fixes the adjustment ruler 31 to the handheld part 1.

[0033] In one optional setting of the tooth pitch adjustment structure 3, see [link to configuration]. Figure 1 As shown, the handheld part 1 is provided with a through hole parallel to the combing part at the position where it is connected to the combing part. The first comb tooth 2 is provided with a slot 21. After the adjusting ruler 31 is inserted into the through hole, the second comb tooth 32 is located in the slot 21. The locking member 33 is provided at both ends of the adjusting ruler 31.

[0034] Furthermore, the slot 21 is a through slot provided on the first comb tooth 2, and the second comb tooth 32 moves in the direction of the previous first comb tooth 2 or the next first comb tooth 2 within the through slot of the first comb tooth 2.

[0035] In another optional configuration of the tooth spacing adjustment structure 3 (not shown in the figures), the surface of the handheld part 1 is provided with a sliding groove parallel to the combing part. The adjusting ruler 31 is located outside the handheld part 1 and is fixed in the sliding groove by the locking member 33. Each second comb tooth 32 contacts the surface of one of the first comb teeth 2. During operation, if it is necessary to adjust the tooth spacing, the locking member 33 is loosened to allow the adjusting ruler 31 to slide and adjust its position within the sliding groove. After the tooth spacing is adjusted appropriately, the locking member 33 is used to tighten and fix the adjusting ruler 31.

[0036] Furthermore, in order to facilitate the insertion of the first comb tooth 2 and the second comb tooth 32 between the pins of the through-hole connector, the free ends of the first comb tooth 2 and the second comb tooth 32 are both tapered. At the same time, in order to avoid the first comb tooth 2 and the second comb tooth 32 causing wear damage to the pins during the combing process, the surfaces of the first comb tooth 2 and the second comb tooth 32 are both smooth planes.

[0037] Furthermore, in order to avoid static electricity generated by friction between the first comb tooth 2 and the second comb tooth 32 and the pin during the combing process, an anti-static layer is provided on the surface of both the first comb tooth 2 and the second comb tooth 32.

[0038] Furthermore, for easier and more accurate adjustment of the tooth pitch, see [link to relevant documentation]. Figure 1 As shown, the adjustment ruler 31 has a scale.

[0039] Furthermore, the components of the pin combing tool in this invention can be made of H13 hot work die steel, which has the characteristics of being antistatic, wear-resistant and not easily damaged.

[0040] Furthermore, all components of the pin combing fixture in this invention are chamfered to avoid damaging the pins.

[0041] In an improved embodiment of the aforementioned pin combing fixture, a combination button can be provided on the pin combing fixture to combine two pin combing fixtures into a single unit. Specifically, in use, one pin combing fixture is inserted into the pins of the through-hole connector along the row direction, and then the other pin combing fixture is inserted into the pins of the through-hole connector along the column direction. The combination button of the two pin combing fixtures is then connected to form a single unit. See [reference needed] for the assembled fixture. Figure 3 As shown, when sorting the pins of a through-hole connector, both row and column pins can be sorted simultaneously.

[0042] This utility model of pin combing tooling represents a major innovative breakthrough in improving the production capacity of electrical assembly plants. It simplifies the process, reduces costs, and can be widely promoted and used. The distance between the comb teeth can be adjusted through the tooth pitch adjustment structure, allowing it to be used with pins of different pitches on different through-hole connectors. At the same time, the use of pin combing tooling can also prevent connector pin deformation, reduce damage to printed circuit board mounting holes, improve production consistency, and increase production efficiency. It has social value for widespread application.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
