Description

Technical Field

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

[0002] A valve island is a control component composed of multiple electric control valves. With the gradual miniaturization of components, new requirements are put forward for the structural design of the valve island. 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 "CN202021948536.3" and the patent name "An integrated valve island structure", as shown in this patent Figure 1 it shows that sockets for plugging in solenoid valves are arranged on the upper surface of the PCB board, and the pins of the solenoid valves are horizontally plugged into the sockets; this horizontally plugging structural design requires a large installation space in the horizontal direction. Therefore, the interface board mounting structure of the existing pin-type valve island occupies a large volume, resulting in a large size of the valve island structure, and it can no longer match the development trend of the gradual miniaturization of components.

[0003] In addition, the existing pin-type 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 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 pin-type valve islands do not support this.

[0004] In view of this, how to effectively reduce the size of the valve island and improve the applicable range of the valve island has become an urgent technical problem in this field.

[0005] The above information is given as background information only to assist in understanding the present disclosure, and it is not determined or admitted whether any of the above content can be used as prior art relative to the present disclosure. Summary of the Utility Model

[0046] Embodiment 1:

[0047] Please refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 5 , Figure 1 Figure 19 is the structural schematic diagram of a pin-type remote I / O valve island provided by an embodiment of the present utility model, Figure 3 Figure 20 is Figure 1 the enlarged structural diagram at position A in Figure 19, Figure 4 Figure 21 is Figure 1 the enlarged structural diagram at position B in Figure 19, Figure 5 Figure 22 is Figure 1 the enlarged structural diagram at position C in Figure 19.

[0048] The pin-type remote I / O valve island adopts a vertical plug-in interface board installation structure, specifically as follows:

[0049] It includes an installation cavity 110 formed inside the valve island body 100. An interface board 600 is vertically installed in the installation cavity 110. An interface board end connector 602 and a plurality of solenoid valve interface connectors 603 are installed on one side of the interface board 600; the sockets of the interface board end connector 602 and the solenoid valve interface connectors 603 are all arranged towards the top side of the valve island body 100;

[0050] Please combine Figure 1 andFigure 2 , Figure 2 is the structural schematic diagram of the driving and control module provided by the embodiment of the present utility model; an avoidance hole 120 is opened at the top of the valve island body 100 corresponding to the position of the interface board end connector 602; the interface board between connectors 205 of the driving and control module 200 can pass through the avoidance hole 120 and extend into the installation cavity 110, and is electrically plugged into the interface board end connector 602;

[0051] At the top of the valve island body 100, jacks 500 are respectively opened corresponding to the positions of the solenoid valve interface connectors 603; the plugs of the solenoid valves 300 can pass through the jacks 500 and extend into the installation cavity 110, and are electrically plugged into the solenoid valve interface connectors 603.

[0052] The interface board installation structure provided by the present utility model changes from the traditional horizontal plugging method to the vertical plugging method, making full use of the installation space in the vertical direction of the valve island, greatly reducing the occupied area of the interface board installation structure in the horizontal direction, so that the structural size of the valve island body can be further reduced.

[0053] Specifically, as Figure 3 shown, on the inner wall of the installation cavity 110 (that is, Figure 3 in, the upper and lower inner walls of the installation cavity 110), two positioning sliding grooves 111 for positioning the interface board 600 are oppositely arranged; the two long sides of both sides of the interface board 600 are slidably clamped with the corresponding positioning sliding grooves 111; in this embodiment, the interface board 600 is a rectangular board, and its long side is the side of the interface board 600 extending along the Figure 1 in the X direction, that is, Figure 1 in, the upper and lower side edges of the interface board 600;

[0054] At least one end of the valve island body 100 is provided with an opening leading to the installation cavity 110; the opening is sealed with an end face cover plate 900.

[0055] When installing the interface board 600, the opening is open, that is, the end face cover plate 900 has not been sealed yet. At this time, the two long sides of one end of the interface board 600 are respectively aligned with the corresponding positioning sliding grooves 111, and the interface board 600 is gradually inserted into the installation cavity 110 along the Figure 1 in the X direction. After the installation of the interface board 600 is completed, the end face cover plate 900 is bonded and fixed to the edge of the opening with strong glue to seal the opening for waterproof and dustproof purposes.

[0056] Specifically, as Figure 5 shown, the solenoid valve interface connector 603 includes an installation carrier 6032, and a connector socket 6031 is arranged on the installation carrier 6032; the installation carrier 6032 is fixedly installed on the PCB board 601 of the interface board 600;

[0057] The mounting carrier 6032 is formed with a lapping portion 6033 extending away from the PCB board 601; on the inner wall of the mounting cavity 110, a step 112 for supporting the lapping portion 6033 is formed at a position corresponding to the lapping portion 6033.

[0058] In this embodiment, since the solenoid valve and the connector socket 6031 are vertically inserted, the step 112 supports the lapping portion 6033, so that when the connector socket 6031 inserts the solenoid valve, there is a vertical supporting force to offset the insertion force of the solenoid valve, which can effectively improve the insertion stability of the connector socket 6031. And because the connector socket 6031 is fixedly connected to the PCB board 601, the step 112 supports the lapping portion 6033, which can further limit the position of the PCB board 601 in the mounting cavity 110 and further ensure the mounting stability of the interface board 600.

[0059] Specifically, a through-limiting block 800 with both ends passing through and adapted to the shape of the interface board-to-board connector 205 is installed in the avoidance hole 120 for limiting the insertion path of the interface board-to-board connector 205.

[0060] Please refer to Figures 1 - 4 , after the interface board 600 is installed in the mounting cavity 110 and before the drive control module 200 is installed, first install the limiting block 800 into the avoidance hole 120. The limiting block 800 can limit the insertion path of the interface board-to-board connector 205, so that the interface board-to-board connector 205 can be accurately vertically inserted onto the interface board end connector 602.

[0061] Furthermore, after the interface board 600 is installed in the mounting cavity 110, this embodiment also limits its position in the horizontal direction (i.e., Figure 1 the X direction in ). As an optional implementation manner, openings are provided at both ends of the valve island body 100, and two end face covers 900 are respectively abutted against both ends of the interface board 600; or, as another optional implementation manner, an opening is provided at one end of the valve island body 100, and both ends of the interface board 600 are respectively abutted against the end face cover 900 and the inner wall of the mounting cavity 110.

[0062] Through the above structural design, the interface board 600 is limited by the inner wall of the mounting cavity 110 and the step 112 in the height direction (Y direction), limited by the end face cover 900 or the inner wall of the mounting cavity 110 in the length direction (X direction), and limited by the positioning sliding groove 111 in the width direction (the direction perpendicular to both the X direction and the Y direction). In this way, the mounting structure of the interface board 600 is very stable, not prone to position deviation, and is beneficial to the accurate insertion of the solenoid valve.

[0063] Embodiment 2:

[0064] Please refer toFigure 1 , Figure 1 This is the structural schematic diagram of a pin - type remote I / O valve island provided by an embodiment of the present utility model.

[0075] In addition, a pin-type remote I / O valve island provided in this embodiment can support up to 24 solenoid valves at most, and single and double coils can be mixedly installed, further expanding the applicable range of the valve island.
