Description

Technical Field

[0001] This utility model relates to the field of mechanical limit switches, specifically a driver-driven limit switch. Background Technology

[0002] Currently, all diodes and wires are installed manually. In particular, the diode installation is complicated because the total length of the diode is greater than the pin spacing of the limit switch. Therefore, the diode needs to be inserted diagonally downwards into one of the pin holes first, then laid flat, and then inserted into the other pin hole in the opposite direction.

[0003] Furthermore, because the diode and the wire are threaded together through the pin hole, the pin hole cannot be made small, otherwise it would be difficult for a person to pass through it manually. Therefore, the pin hole cannot secure the diode and the wire. During subsequent movement, handling, and soldering, the diode or wire often moves outside the hole, leading to soldering failure or defects, requiring manual rework.

[0004] Therefore, there is an urgent need to develop a driver limit switch that is easy to install for fixing diodes and wires. Summary of the Invention

[0005] The purpose of this invention is to provide a driver limit switch to solve the problems mentioned in the background art.

[0006] The technical solution of this utility model is: a driver limit switch, including a limit switch body and mounting pins, wherein there are at least two sets of mounting pins, which are respectively located on the left and right sides of the limit switch body, and a middle slot is provided on the mounting pins, wherein a clamping area for clamping wires and diode conductors is provided in the middle of the middle slot.

[0007] Preferably, the limit switch body is provided with a mounting groove, and a portion of the mounting pins are inserted into the mounting groove, while the other portion protrudes outside the mounting groove.

[0008] Preferably, the upper end of the mounting pin is provided with a slit guide angle, and the upper end of the middle slit is connected to the slit guide angle.

[0009] As a further preferred embodiment, the angle of the slot guide angle is 120±5°.

[0010] Preferably, the clamping area for clamping the wire and diode conductor is a vertically arranged waist-shaped groove, with an arc transition between the upper and lower ends of the waist-shaped groove and the middle gap. The width of the waist-shaped groove is smaller than the corresponding clamping object, i.e., smaller than the diameter of the wire and diode conductor.

[0011] As a further preferred embodiment, the width of the intermediate gap is smaller than the width of the waist groove, and the difference between the width of the intermediate gap and the width of the waist groove is 0.1 to 0.3 mm.

[0012] As a further preferred embodiment, the height of the mounting pin protruding from the main body of the limit switch is 3.6±0.5mm, the length of the groove hole is 1.2±0.2mm, and the height of the groove hole is 1.5±0.2mm.

[0013] Preferably, the clamping area for clamping the wire and the diode conductor includes a wire fixing hole and a diode fixing hole, wherein the wire fixing hole is used to clamp the wire and the diode fixing hole is used to clamp the diode conductor; the diameter of the wire fixing hole is smaller than the diameter of the wire and the diameter of the diode fixing hole is smaller than the diameter of the diode conductor.

[0014] As a further preferred embodiment, the width of the intermediate gap is smaller than the minimum of the diameter of the wire fixing hole and the diameter of the diode fixing hole, and the difference between the width of the intermediate gap and the minimum of the diameters of the wire fixing hole and the diode fixing hole is 0.1 to 0.3 mm.

[0015] As a further preferred embodiment, the height of the mounting pin protruding above the limit switch body is 3.6±0.5mm, and the distance between the wire fixing hole and the diode fixing hole is 0.7±0.2mm.

[0016] Compared with existing technologies, the advantages of this invention are as follows: Based on the existing limit switch shape, this invention improves the pin shape and connects the diode, tin-plated wire, and mounting pin by pressing them together. This is simple, efficient, and facilitates automated production. Furthermore, the mounting pin exerts a certain clamping force on the diode and wire, limiting the displacement between the two components and greatly reducing defects and rework.

Detailed Implementation

[0018] Example 1 like Figures 1-4 As shown, a driver limit switch includes a limit switch body 1 and mounting pins 2. The mounting pins 2 are at least two sets, respectively located on the left and right sides of the limit switch body 1. A central slot 9 is provided on the mounting pins 2, and a clamping area for clamping the wire 3 and the diode conductor 4 is provided in the middle of the central slot 9.

[0019] In this embodiment, the limit switch body 1 is provided with a mounting groove, and a portion of the mounting pin 2 is inserted into the mounting groove, while the other portion protrudes outside the mounting groove.

[0020] In this embodiment, the upper end of the mounting pin 2 is provided with a slot guide angle 5, and the upper end of the middle slot 9 is connected to the slot guide angle 5. The slot guide angle 5 is provided to facilitate the accurate pressing of the wire 3 and the diode conductor 4 into the lower middle slot 9.

[0021] In this embodiment, the angle B of the guide angle 5 of the slot is 120±5°. Experiments have verified that this angle is the most convenient for operation.

[0022] In this embodiment, the clamping area for holding the wire 3 and the diode conductor 4 is a vertically arranged slotted hole 6. The upper and lower ends of the slotted hole 6 are curved transitions to the middle gap 9. The width of the slotted hole 6 is smaller than the corresponding clamping object, i.e., smaller than the diameter of the wire 3 and the diode conductor 4. This configuration is suitable when the diameters of the wire 3 and the diode conductor 4 are relatively close, and when the spacing requirement between the wire 3 and the diode conductor 4 is not high.

[0023] In this embodiment, the width G of the intermediate gap 9 is smaller than the width of the waist groove 6, and the difference between the width of the intermediate gap 9 and the width of the waist groove 6 is 0.1 to 0.3 mm, which is used to form a step to facilitate the positioning of the diode and the wire 3. In order to form a step, the width G of the intermediate gap 9 should be as small as possible. However, if the width G of the intermediate gap 9 is too small, it will result in too large a clamping force in the intermediate gap 9, making it difficult to press the wire 3 and the diode conductor 4 in.

[0024] In this embodiment, the height A of the mounting pin 2 protruding from the limit switch body 1 is 3.6±0.5mm, the length D of the groove hole 6 is 1.2±0.2mm, and the height E of the groove hole 6 is 1.5±0.2mm.

[0025] In actual processing, the worker only needs to press the two ends of the diode conductor 4 into the slots 6 of the mounting pins 2, and then press the two wires 3 into the slots 6 of the two mounting pins 2, so that they are in contact with the two ends of the diode conductor 4, and then proceed with the subsequent soldering process. The above process can also be automated. The height H of the middle gap 9 should be higher than that of a conventional pin to prevent molten solder from flowing onto the limit switch body.

[0026] Example 2 like Figures 5-8 As shown, a driver limit switch includes a limit switch body 1 and mounting pins 2. The mounting pins 2 are at least two sets, respectively located on the left and right sides of the limit switch body 1. A central slot 9 is provided on the mounting pins 2, and a clamping area for clamping the wire 3 and the diode conductor 4 is provided in the middle of the central slot 9.

[0027] In this embodiment, the limit switch body 1 is provided with a mounting groove, and a portion of the mounting pin 2 is inserted into the mounting groove, while the other portion protrudes outside the mounting groove.

[0028] In this embodiment, the upper end of the mounting pin 2 is provided with a slot guide angle 5, and the upper end of the middle slot 9 is connected to the slot guide angle 5. The slot guide angle 5 is provided to facilitate the accurate pressing of the wire 3 and the diode conductor 4 into the lower middle slot 9.

[0029] In this embodiment, the angle B of the guide angle 5 of the gap is 120±5°.

[0030] In this embodiment, the clamping area for the wire 3 and the diode conductor 4 includes a wire fixing hole 8 and a diode fixing hole 7. The wire fixing hole 8 is used to clamp the wire 3, and the diode fixing hole 7 is used to clamp the diode conductor 4. The diameter of the wire fixing hole 8 is smaller than the diameter of the wire 3, and the diameter of the diode fixing hole 7 is smaller than the diameter of the diode conductor 4. This configuration is suitable for situations where the diameters of the wire 3 and the diode conductor 4 are not very close, and where the required spacing between the diode conductor 4 and the wire 3 is relatively high. By clamping the wire 3 with the wire fixing hole 8 and the diode with the diode fixing hole 7, the spacing between the two can be accurately controlled.

[0031] In this embodiment, the width G' of the intermediate gap 9 is smaller than the minimum of the diameters of the wire fixing hole 8 and the diode fixing hole 7, and the difference between the width of the intermediate gap 9 and the minimum of the diameters of the wire fixing hole 8 and the diode fixing hole 7 is 0.1 to 0.3 mm. This is used to form a step, facilitating the positioning of the diode and the wire 3. To form the step, the smaller the width of the intermediate gap 9, the better. However, if the width of the intermediate gap 9 is too small, the clamping force of the intermediate gap 9 will be too large, making it difficult to press the wire 3 and the diode conductor 4 in.

[0032] In this embodiment, the height A' of the portion of the mounting pin 2 exposed above the limit switch body 1 is 3.6±0.5mm, and the distance D' between the wire fixing hole 8 and the diode fixing hole 7 is 0.7±0.2mm.

[0033] In actual processing, the worker only needs to press the two ends of the diode conductor 4 into the diode mounting hole 7, and then press the two wires 3 into the wire mounting holes 8 of the two mounting pins 2, and then proceed with the subsequent soldering process. The height H of the middle gap 9 should be higher than that of a regular pin to prevent molten solder from flowing onto the limit switch body.
