Description

Technical Field

[0001] This utility model relates to the field of electrical control technology, and specifically to a pin holding tool for a multi-row pin connector. Background Technology

[0002] In the field of electronic control, electrical connectors transmit electronic signals and current through the contact of pins. Electrical connectors are frequently used in various control applications to transmit signals or current. With the advancement of technology, the complexity of electronic control is increasing, leading to an increase in the number of pins in electrical connectors, and the widespread use of multi-row pin connectors. When the number of contact pins in an electrical connector is large, deformation or displacement of the pins can easily cause installation difficulties. Their installation is affected by whether the pins can make proper contact. The ability to efficiently and quickly install multi-row pin connectors is crucial to the speed and efficiency of the electronic assembly process, making the innovative design of installation tools imperative. Utility Model Content

[0003] The purpose of this invention is to provide a pin holding tool for multi-row pin electrical connectors, which solves the problem that electrical connectors with a large number of contact pins are prone to installation difficulties due to pin deformation and displacement.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A pin holding tool for a multi-row pin connector is used to insert the multi-row pin connector onto a circuit board. The multi-row pin connector has three or more rows of pins, including two rows of outer pins and one or more rows of inner pins disposed between the two rows of outer pins. The number of outer pins is one more than the number of inner pins, and the outer pins and inner pins are staggered.

[0006] The pin retaining tool includes a pin retaining plate and two clamps, which are respectively fitted onto both ends of the pin retaining plate to fix the pin retaining plate.

[0007] The pin retaining plate is inserted into the gap between two adjacent rows of pins to maintain the position of the pins. The pin retaining plate is long and narrow, with corresponding semi-circular grooves on its two sides to accommodate the corresponding pins. The minimum width between the semi-circular grooves on the two sides is equal to the gap between two adjacent rows of pins, and the distance between adjacent semi-circular grooves is equal to the distance between two adjacent pins.

[0008] The pin retaining plate includes at least two staggered hole retaining plates, which are inserted into the gaps between adjacent outer row pins and inner row pins to retain the position of the pins; the two sides of the staggered hole retaining plate are staggeredly provided with semi-circular grooves for receiving pins, one side is provided with a number of semi-circular grooves equal to or greater than the number of outer row pins, and the other side is provided with a number of semi-circular grooves equal to or greater than the number of inner row pins, the semi-circular grooves on the two sides are staggered, and the diameter of the semi-circular groove is at least equal to the diameter of the pin;

[0009] When the inner row of pins of a multi-row pin connector is arranged in two or more rows, the pin retaining plate also includes a symmetrical hole retaining plate. The symmetrical hole retaining plate is inserted into the gap between two adjacent rows of inner row pins to retain the position of the pins. The two long sides of the symmetrical hole retaining plate are symmetrically provided with semi-circular grooves to accommodate the pins. The two sides of the symmetrical hole retaining plate are provided with a number of semi-circular grooves equal to or greater than the number of inner row pins.

[0010] The staggered hole retaining plate is rectangular, and its two long sides are staggered with semi-circular grooves for accommodating pins. The minimum width between the semi-circular grooves on the two long sides of the staggered hole retaining plate is equal to the gap between adjacent outer row pins and inner row pins.

[0011] The symmetrical hole retainer plate is rectangular, and its two long sides are symmetrically provided with semi-circular grooves to accommodate pins. The minimum width between the semi-circular grooves on the two long sides of the symmetrical hole retainer plate is equal to the gap between two adjacent rows of inner pins.

[0012] Four staggered hole retaining plates are provided. Each row of outer pins is held by two staggered hole retaining plates. One staggered hole retaining plate is inserted into the gap between the adjacent outer and inner pins. The other staggered hole retaining plate is located on the outside of the outer pins. The semi-circular grooves of the two staggered hole retaining plates together form a circular hole for holding the pins.

[0013] The clamp has a square hole, the length of which is the sum of the widths of all the pin retaining plates used.

[0014] The advantages of this utility model are as follows: 1. The width between the semi-circular grooves of the staggered hole retaining plate and the symmetrical hole retaining plate is the same as the inter-row gap of the pins of the multi-row pin connector, and the position of the semi-circular groove is the same as the position of the pins of the multi-row pin connector, which can conveniently and accurately insert the pins into the gap and adjust the pin position; 2. The number of pin retaining plates can be flexibly adjusted according to the number of pins of different models of multi-row pin connectors, which has good mobility and strong adaptability; 3. This utility model can correct the deformed and displaced pins in the multi-row pin connector, so that each pin returns to the correct position, thereby facilitating the rapid installation of the multi-row pin connector. It is ingeniously designed and highly practical. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings. The drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent.

[0020] To simplify the description of this embodiment, some components that are well-known to those skilled in the art but are not related to the main content of this invention may be omitted in the accompanying drawings or description. Additionally, for ease of description, some components in the drawings may be omitted, enlarged, or reduced, but these do not represent the actual product dimensions or the complete structure.

[0021] This utility model discloses a pin holding tool for a multi-row pin electrical connector, such as... Figure 1 As shown, a multi-row pin connector 1 is used to insert into a circuit board. The multi-row pin connector 1 is provided with three or more rows of pins, including two outer rows of pins 11 arranged on the outermost side, and one or more inner rows of pins 12 arranged between the two outer rows of pins 12. The number of outer rows of pins 11 is one more than the number of inner rows of pins 12. The outer rows of pins 11 and the inner rows of pins 12 are arranged alternately.

[0022] Existing multi-row pin connectors 1 have pins in two, three, four, or more rows. The outermost two rows of pins 11 each have 19 pins, while the rest are inner rows of pins 12, each with 18 pins. That is, a three-row pin connector includes two rows of outer pins 11 and one row of inner pins 12; a four-row pin connector includes two rows of outer pins 11 and two rows of inner pins 12. Because each row of outer pins 11 has the same 19 pins, and each row of inner pins 12 has 18 pins, the outer and inner pins 11 are arranged alternately due to the difference in the number of pins between them.

[0023] Connecting a two-row pin connector to a circuit board is relatively easy, but connecting a connector with three, four, or more rows of pins to a circuit board is very troublesome. Often, the pins cannot be inserted into the corresponding sockets on the circuit board due to deformation or displacement.

[0024] This utility model's pin holding tool is designed to solve the difficulty of connecting electrical connectors with three or more rows of pins to circuit boards. This installation tool, such as... Figure 1 As shown, it includes a pin retaining plate and two clamps 4, which are respectively fitted onto both ends of the pin retaining plate to fix the pin retaining plate; the clamps 4 have square holes, the length of which is the sum of the widths of all the pin retaining plates used.

[0025] The pin retaining plate is inserted into the gap between two adjacent rows of pins to maintain the position of the pins. The pin retaining plate is long and narrow, with corresponding semi-circular grooves 5 on its two sides to accommodate the corresponding pins. The minimum width between the semi-circular grooves 5 on the two sides is equal to the gap between two adjacent rows of pins, and the distance between adjacent semi-circular grooves 5 is equal to the distance between two adjacent pins.

[0026] The pin retaining plate can be either cuboid or cylindrical. The preferred shape for the pin retaining plate in this invention is cuboid.

[0027] The pin retainer plate includes at least the following: Figure 2 The two staggered hole retaining plates 2 shown are combined with Figure 1 The staggered hole retaining plate 2 is inserted into the gap between the adjacent outer row of pins 11 and the inner row of pins 12 to hold the position of the pins. The staggered hole retaining plate 2 is rectangular, and its two long sides are staggered with semi-circular grooves 5 to accommodate the pins. One long side has a number of semi-circular grooves 5 equal to or greater than the number of outer row of pins 11, and the other long side has a number of semi-circular grooves 5 equal to or greater than the number of inner row of pins 12. The semi-circular grooves 5 on the two long sides are staggered, and the diameter of the semi-circular groove 5 is at least equal to the diameter of the pin. In this way, when the two pin retaining plates overlap, the two semi-circular grooves 5 form a circular hole, which can just clamp the pin.

[0028] Furthermore, the minimum width between the semicircular grooves 5 on the two long sides of the staggered hole retaining plate 2 is equal to the gap between adjacent outer row pins 11 and inner row pins 12. The purpose of this design is to ensure that the pins do not shift or deform when the staggered hole retaining plate 2 is inserted. When a pin cannot enter the semicircular groove 5, it indicates that the pin has been deformed or shifted. The deformed or shifted pin can be corrected by simply bending it into the corresponding semicircular groove 5.

[0029] When the inner row of pins 12 of the multi-row pin connector 1 has two or more rows, such as Figure 3As shown, a symmetrical hole retaining plate 3 is also provided. The symmetrical hole retaining plate 3 is inserted into the gap between two adjacent rows of inner row pins 12 to maintain the position of the pins. The symmetrical hole retaining plate 3 is rectangular, and two long sides are symmetrically provided with semi-circular grooves 5 to accommodate the pins. Both long sides of the symmetrical hole retaining plate 3 are provided with a number of semi-circular grooves 5 equal to or greater than the number of inner row pins 12.

[0030] Furthermore, the minimum width between the semicircular grooves 5 on the two long sides of the symmetrical hole retaining plate 3 is equal to the gap between the two adjacent rows of inner pins 12.

[0031] To better ensure the alignment of the pins with the circuit board's insertion holes, four staggered hole retaining plates 2 are provided. Each row of outer pins 11 is clamped by two staggered hole retaining plates 2. One staggered hole retaining plate 2 is inserted into the gap between the adjacent outer pin 11 and the inner pin 12, while the other staggered hole retaining plate 2 is located on the outside of the outer pin 11. The semi-circular grooves 5 of the two staggered hole retaining plates 2 together form a circular hole for clamping the pins.

[0032] Taking a four-row 90° bend 74-pin electrical connector as an example, before installation, the position of each pin in the multi-row pin connector 1 is checked. The gap between every two rows of pins in the multi-row pin connector 1 is 2mm, and the gap between adjacent pins is also 2mm. The diameter of the pin is 0.6mm. Therefore, the width between the lowest points of the semicircular grooves 5 on the two long sides of the staggered hole retaining plate 2 is 2mm, the distance between adjacent semicircular grooves 5 is 2mm, and the diameter of the semicircular groove 5 is 0.8mm, slightly larger than the pin diameter. The width between the lowest points of the semicircular grooves 5 on the two long sides of the symmetrical hole retaining plate 3 is also 2mm, the distance between adjacent semicircular grooves 5 is also 2mm, and the diameter of the semicircular groove 5 is also 0.8mm.

[0033] In use, insert the two staggered hole retaining plates 2 into the gap between the adjacent outer row of pins 11 and the inner row of pins 12, so that the outer row of pins 11 and the inner row of pins 12 enter the corresponding semi-circular grooves 5 on the two long sides of the staggered hole retaining plates 2, and check whether there are any pins in the two adjacent rows of pins that have not entered the semi-circular grooves 5 due to deformation or displacement, and bend them into the corresponding semi-circular grooves 5 to return them to their original positions;

[0034] Next, insert the symmetrical hole retaining plate 3 into the gap between the adjacent inner row of pins 12, so that the inner row of pins 12 are constrained within the circular hole formed by the semi-circular groove 5 of the symmetrical hole retaining plate 3 and the semi-circular groove 5 of the corresponding staggered hole retaining plate 2. Finally, clamp one staggered hole retaining plate 2 on the outside of the outermost outer row of pins 11, so that the outermost outer row of pins 11 are constrained within the corresponding circular hole formed by the semi-circular grooves 5 of the two staggered hole retaining plates 2. After all four rows of pins are in the correct position, clamps 4 are fitted onto both ends of the pin retaining plate to fix the staggered hole retaining plate 2 and the symmetrical hole retaining plate 3. The clamps 4 maintain the position of the pin retaining plate, and the corrected multi-row pin connector 1 can be quickly installed onto the circuit board, achieving a convenient installation effect.

[0035] When the head of the pin of the multi-row pin connector 1 is inserted into the socket of the circuit board, remove the clamp 4, rotate the pin holding board clockwise or counterclockwise by an angle and pull it out, and then fully insert the pin into the socket of the circuit board.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made within the scope of the claims of this utility model should be considered within the technical scope of this utility model.
