Description

Technical Field

[0001] The utility model relates to the technical field of plug-in valve islands, in particular to an interface board mounting structure and a plug-in remote I / O valve island. Background Art

[0002] A valve island is a control component composed of multiple electrically controlled valves. It integrates signal input / output and signal control, just like a control island. The advantage of the valve island is that it simplifies the installation and debugging process, reduces the installation workload and cost.

[0003] Currently, for the valve islands sold on the market, their interface boards generally adopt a horizontal installation method. For example, in a Chinese patent with the application number "CN201821455496.1" and the patent name "A fieldbus type valve island", as shown in this patent Figure 1 its PCB board is horizontally and fixedly arranged on the busbar plate, the solenoid valves are horizontally arranged and fixed on the busbar plate, and connection plug terminals connected to the solenoid valves are arranged on the upper surface of the PCB board; this horizontal installation method occupies a large space, thus resulting in a relatively large size of the valve island product and being unable to match the development trend of the gradual miniaturization of components.

[0004] In addition, for the existing plug-in valve islands, the solenoid valves generally adopt a loose wire arrangement. When wiring, it is necessary to distinguish between the positive and negative poles. Especially when the number of solenoid valves on the valve island is relatively large, the wiring is particularly troublesome and it is very easy to make mistakes, thus resulting in equipment damage; moreover, the existing plug-in valve islands have special limitations on the installation positions of their solenoid valves. For example, for the 1-24 position solenoid valve installation positions, generally the first 2-3 positions are limited to double-coil solenoid valves, while the 4-24 positions cannot install double-coil solenoid valves and can only install single-coil solenoid valves, which is very inconvenient. In practical applications, many scenarios often require a mixed installation of single-coil solenoid valves, double-coil solenoid valves and empty positions (no solenoid valve but with a blank plate), but the existing plug-in valve islands do not support this.

[0005] In view of this, how to effectively reduce the size of the valve island and further improve the usability of the valve island has become an urgent technical problem in this field.

[0043] Embodiment 1:

[0044] Please refer to Figures 1 - 3 , Figure 1 which is the structural schematic diagram of a plug-in type remote I / O valve island provided by the embodiments of the present utility model. Figure 2 It is Figure 1 the enlarged structure diagram at position C in Figure 3 It is Figure 1 the enlarged structure diagram at position D in

[0045] The plug-in type remote I / O valve island adopts a vertical installation type interface board installation structure, specifically as follows:

[0046] Installation grooves 110 are respectively formed on the opposite sides of the valve island body 100, and an interface board 500 is slidably clamped and fixed in the installation grooves 110; in this embodiment, the opposite sides of the valve island body 100 refer to the two sides of the valve island body 100 in its width direction;

[0047] A plurality of interface connectors 503 are arranged on the interface board 500. One end of a solenoid valve connecting wire 800 is inserted into the interface connector 503, and the other end of the solenoid valve connecting wire 800 is provided with an anti-fooling plug seat for electrically connecting to the solenoid valve 300 on the valve island body 100. The anti-fooling plug seat can only be inserted and fixed to the wire plug on the solenoid valve 300 in a preset insertion posture.

[0048] As Figure 1As shown, after the interface board installation structure is changed from the traditional horizontal installation method to the vertical installation method, the width direction of the valve island body 100 can be further reduced in size. Such a setting can make full use of the installation space inside the valve island body. In addition, the anti-fooling plug socket adopts an anti-fooling structure design. It can only be plugged and fixed with the wire plug on the solenoid valve in a predetermined posture. When the user inserts it reversely (i.e., the positive and negative poles are inserted reversely), the anti-fooling structure on the anti-fooling plug socket will block the wire plug and prevent it from being inserted into the anti-fooling plug socket. And, on the surface of the anti-fooling plug socket, it generally also shows whether the insertion surface or the insertion posture is correct. For example, a predetermined mark or reminder text is set on the upward side surface. Therefore, in this embodiment, after adopting the anti-fooling plug socket, it is no longer necessary for the staff to confirm the positive and negative poles during wiring, which greatly reduces the wiring burden of the staff and can also avoid the phenomenon of incorrect connection of the positive and negative poles.

[0049] Specifically, please refer to Figure 1 and Figure 2 , the installation groove 110 is a strip-shaped groove, and at least one end of the two ends in its length direction is set to be open;

[0050] On the two side walls of the installation groove 110 ( Figure 2 the upper and lower inner walls of the installation groove 110 in Figure 1 ), sliding card slots 111 are symmetrically provided respectively; the interface board 500 can be slidably inserted into the sliding card slots 111 in the installation groove 110 from the opening; as Figure 1 shown, the interface board 500 can be inserted into the installation groove 110 along the

[0051] X-axis direction in

[0052] It can be understood that there are many ways to implement the sliding card slot 111. More specifically, in this embodiment, the sliding card slot 111 is formed by enclosing two parallel strip-shaped protrusions formed on the two side walls of the installation groove 110.

[0053] In this embodiment, the interface board 500 adopts a sealed structure design, which can prevent dust from contacting the interface board 500. Specifically, the opening of the installation groove 110 is sealed with an end face cover plate 600, and the notch of the installation groove 110 is sealed with a side cover plate 400; avoidance openings are respectively opened on the side cover plate 400 at positions corresponding to each interface connector 503.

[0054] On the two side walls of the installation groove 110, arc-shaped limiting protrusions 112 are also symmetrically provided respectively. The limiting protrusions 112 are located between the sliding card slot 111 and the notch of the installation groove 110; Figure 1As shown, during installation, the side cover plate 400 is gradually inserted into the installation groove 110 from the notch direction of the installation groove 110 (i.e., the Y-axis direction in Figure 1 ), and the outer end of the elastic flange 410 will be pushed up by the limiting rib 112 until the limiting card slot 411 is engaged and fixed with the limiting rib 112, that is, the fixed installation of the side cover plate 400 and the installation groove 110 is completed.

[0055] As an alternative implementation, in this embodiment, the end face cover plate 600 and the opening of the installation groove 110 are adhesively fixed with strong glue.
