[0002] There are two manufacturing processes for the fixtures used to fix the PCB board in the existing safety-type industrial control I / O relay combination module, one is injection molding and the other is extrusion molding. When injection molding is used, the product precision is high, but due to the limitations of the mold manufacturing process and cost control, the length of the fixture cannot normally exceed 100mm. Therefore, when the length of the fixture exceeds 100mm, plastic extrusion molding is required. When the length of the fixture exceeds 300mm, it is necessary to add a mounting bracket in the middle of the fixture, but the current manufacturing tolerance accuracy of extrusion molding can only guarantee ±0.25mm, which is not conducive to assembling a mounting bracket with a damping effect in the middle of the fixture.

[0027] In this embodiment, the sliding guide structure includes a guide column 31 provided on the top surface of the second mounting bracket 3 and a slide groove 11 provided on the bottom surface of the fixing member 1 along its length direction. The guide column 31 and the slide groove 11 are slidably matched, and the two are roughly matched, and the process accuracy requirements for the second mounting bracket 3 and the fixing member 1 are not high. The two ends of the slide groove 11 in the length direction are respectively opened, and the notch of the slide groove 11 is downward and in a constricted shape. The guide column 31 slides into the slide groove 11 from the opening at one end of the slide groove 11. The number of the slide grooves 11 is two, but not limited to this. The two slide grooves 11 are spaced apart along the width direction of the fixing member 1, and the number of the guide columns 31 is also two, and the two guide columns 31 correspond to the two slide grooves 11 one by one.

[0028] In this embodiment, the cross section of the slide groove 11 is C-shaped, and the outer contour of the cross section of the guide column 31 is circular.

[0029] In this embodiment, a snap-on structure is also provided between the second mounting bracket 3 and the fixing member 1. The snap-on structure specifically includes a snap-on head 32 provided on the second mounting bracket 3 and a snap-on slot 12 provided on the fixing member 1 along its length direction, and the snap-on head 32 is snapped into the snap-on slot 12. There are two snap-on structures, and the two snap-on structures are distributed along the width direction of the fixing member 1. The sliding guide structure is located between the two snap-on structures. The notch of the snap-on slot 12 is downward, and the two ends of the snap-on slot 12 in the length direction are respectively open. The upper part of the snap-on head 32 slides into the snap-on slot 12 from the opening at one end of the snap-on slot 12, and the lower part of the snap-on head 32 slides into the notch of the snap-on slot 12. Specifically, the cross section of the snap-on head 32 is in an inverted L shape, and its horizontal part constitutes the upper part of the snap-on head, and its vertical part constitutes the lower part of the snap-on head.

[0030] In this embodiment, the anti-slip structure is located between the two guide posts 31 of the second mounting bracket 3, but is not limited thereto. The protective structure specifically includes a plurality of convex ribs 33 provided on the top surface of the second mounting bracket 3, but is not limited thereto.

[0033] A safety type industrial control I / O relay combination module of the present invention is installed by first installing the PCB board 5 on the fixing part 1, and installing the second mounting bracket 3 to the middle part of the fixing part 1 by sliding. At this time, the guide column 31 of the second mounting bracket 3 slides into the slide groove 11 of the fixing part 1, and the second mounting bracket 3 and the fixing part 1 are limited in the horizontal and vertical directions; the clamping head 32 of the second mounting bracket 3 is clamped into the clamping groove 12 of the fixing part 1, and the second mounting bracket 3 and the fixing part 1 are further limited, and the longitudinal connection reliability of the second mounting bracket 3 and the fixing part 1 is increased to prevent falling off; each convex rib 33 of the second mounting bracket 3 is respectively pressed against the bottom surface of the fixing part 1, so that the fixing part 1 and the second mounting bracket 3 are relatively static in the horizontal direction, that is, the anti-slip effect is achieved. The horizontal direction refers to the direction where the length of the fixing part 1 is located, and the longitudinal direction refers to the direction where the thickness of the fixing part 1 is located. Finally, the two first mounting brackets are respectively locked at the two ends of the length direction of the fixing part 1 using two self-tapping screws 4.

[0034] A safety-type industrial control I / O relay combination module of the present invention has a second mounting bracket 3 and an anti-slip structure, so that the second mounting bracket 3 can achieve a damping effect with the fixing part 1 through its anti-slip structure. Therefore, the sliding guide structure of the fixing part 1 and the second mounting bracket 3 can be roughly matched without the need to adopt a high-precision matching method with a damping effect such as a dovetail groove and a dovetail column. Therefore, the manufacturing tolerance accuracy requirement of the fixing part 1 is not high, and the fixing part 1 can be manufactured by an extrusion molding process, thereby meeting the requirements that a fixing part 1 with a longer length needs to be manufactured by extrusion molding and a mounting bracket is arranged in the middle.
