[0037] Please refer to Figures 1 to 5 , this embodiment provides a valve island connection device. This valve island connection device 2 is applied to various types of valve islands, and the above valve islands can be valve islands in a pneumatic control system or valve islands in a hydraulic control system. The valve island includes a plurality of centrally arranged valve bodies 1, and this valve island connection device 2 is used to connect the valve body 1 in the valve island and the signal output device in the valve island. Each valve body 1 is correspondingly provided with one of this valve island connection device 2, and the electrical signal of the valve island is output to each valve body 1 through this valve island connection device 2.

[0038] As Figure 1 shown, in the Figure 1 illustrated embodiment, only one valve body 1 in the valve island is shown. There are a plurality of identical or similar valve bodies 1 in the valve island, and the valve island connection device 2 is provided at the bottom of each valve body 1. As Figure 1 shown, the valve island connection device 2 includes a connection circuit board.

[0039] The connection circuit board is vertically arranged and located below the valve body 1, that is, when the valve body 1 is vertically installed, the normal direction of the connection circuit board is perpendicular to the vertical direction, and the height direction of the connection circuit board is the same as the height direction of the valve body 1. It should be noted that in the present application, the connection circuit board is vertically arranged means that in the case of the normal installation of the valve body 1, the normal direction of the connection circuit board is perpendicular to the vertical direction, and in different installation environments, the normal direction of the connection circuit board is not necessarily perpendicular to the vertical direction. When the valve body 1 is horizontally installed, the normal direction of the connection circuit board is parallel to the vertical direction; when the valve body 1 is installed at a certain angle to the vertical direction, the normal direction of the connection circuit board forms the same angle with the horizontal direction.

[0040] Therefore, in the present application, the connection circuit board is vertically arranged means that the height of the connection circuit board is consistent with the height direction of the valve body 1. As Figure 2 shown, the length direction of the valve body 1 is X, the height direction of the valve body 1 is Z, and the connection circuit board is vertically arranged means that the height direction of the connection circuit board is the same as the height direction of the valve body 1, both being the direction indicated by the arrow Z.

[0041] AsFigure 1 and Figure 2 As shown, a first connection structure 21 for connecting with the electrical connection terminal 11 of the valve body 1 is provided at the top of the connection circuit board, and a second connection structure 22 for connecting the electrical signal output device is provided at the bottom of the connection circuit board. Among them, the electrical signal output device is a signal processing device in an existing valve island. For example, the signal processing device can be a communication master station or a communication slave station of an industrial control computer. The control information of the industrial control computer is first transmitted to the communication master station or the communication slave station, and then transmitted from the communication master station or the communication slave station to the second connection structure 22 in the connection circuit board. Of course, in this application, the signal processing device in the valve island is not limited to the above-mentioned communication master station or communication slave station.

[0042] In the above embodiment, the connection circuit board is vertically arranged, the first connection structure 21 connected to the valve body 1 is arranged at the top of the connection circuit board, and the second connection structure 22 is arranged at the bottom of the connection circuit board. The requirement for the vertical height of the connection board during the installation of the valve body 1 can be met by using one circuit board. Therefore, only one circuit board is needed to meet the requirement of vertical height, which simplifies the structure of the valve island connection board and improves its integration and construction efficiency.

[0043] As Figure 1 、 Figure 3 and Figure 5 As shown, in an embodiment, the first connection structure 21 includes an elastic clip, and the elastic clip includes a first elastic contact piece 211 and a second elastic contact piece 212; the first elastic contact piece 211 is used for electrically connecting with the electrical connection terminal 11, and the second elastic contact piece 212 is arranged on a side of the first elastic contact piece 211 away from the electrical connection terminal 11 and applies an elastic force pointing to the electrical connection terminal 11 to the first elastic contact piece 211.

[0044] Among them, the first elastic contact piece 211 and the second elastic contact piece 212 are an integrally formed structure. The first elastic contact piece 211 is one end of the integrally formed structure, and the second elastic contact piece 212 is formed by bending the other end of the integrally formed structure.

[0045] In this embodiment, the elastic clip can be made of conductive metals such as copper and copper alloy. Enough pressure can be applied to the electrical connection terminal 11 through the first elastic contact piece 211 and the second elastic contact piece 212, so that the electrical connection terminal 11 is reliably electrically connected to the first connection structure 21, and the connection efficiency between the electrical connection terminal 11 and the first connection structure 21 is improved. The electrical connection terminal 11 of the valve body 1 can be directly inserted into the inner side of the elastic clip.

[0046] As Figure 5As shown, the electrical connection terminal 11 includes a first connection piece and a second connection piece that are arranged in parallel with each other. The first connection structure 21 includes two of the elastic clips; the first connection piece and the second connection piece are arranged on two opposite surfaces of the board body 20 of the connection circuit board; one of the elastic clips is opposite to the first connection piece and cooperates with the board body 20 to clamp the first connection piece; the other elastic clip is opposite to the second connection piece and cooperates with the board body 20 to clamp the second connection piece.

[0047] That is, the structure of each electrical connection terminal 11 is a U-shaped structure. The U-shaped structure is inserted into the top of the connection circuit board, so that the first connection piece is located on the first surface (for example, the front surface) of the connection circuit board, and the second connection piece is located on the second surface (for example, the back surface) of the connection circuit board. One of the elastic clips is connected to the first connection piece to apply a pressure pointing to the board body 20 to the first connection piece. Therefore, the first connection piece can be clamped by this elastic clip and the board body 20. Similarly, the second connection piece can be clamped by the other elastic clip and the board body 20.

[0048] The first connection structure 21 of the present application is not limited to the above-mentioned structure of the elastic clip. In other embodiments, the first connection structure 21 and the electrical connection terminal 11 can also adopt other electrical connection methods such as bolt connection, welding, riveting, etc.

[0049] Such as Figure 1 and Figure 2 , in one embodiment, the second connection structure 22 includes a plurality of conductive contact points arranged on the surface of the board body 20 of the connection circuit board. The conductive contact points are similar to the gold fingers of the plug-in board card and can be connected to the corresponding card slots, thereby connecting the connection circuit board to the signal output device.

[0050] Such as Figure 3 As shown, in another embodiment, the second connection structure 22 further includes a connection base 23. The connection base 23 is arranged on the conductive contact points and is provided with jacks corresponding to the conductive contact points and pin headers 24 detachably connected to the jacks.

[0051] The connection base 23 can be made of an insulating material such as plastic. Each conductive contact point is correspondingly provided with a jack, and the size of the jack is adapted to the pin header 24. One end of the pin header 24 is inserted into the jack to be electrically connected to the electrical contact point, and the other end of the pin header 24 is electrically connected to the above-mentioned signal output device.

[0052] Such as Figure 4 As shown, in one embodiment, the valve island connection device 2 further includes a base 25. The base 25 is arranged below the valve body 1, and the base 25 is used to mount the connection circuit board and the valve body 1.

[0053] The top of the base 25 is provided with a mounting groove 251 adapted to the bottom of the valve body 1; the bottom of the valve body 1 is mounted in the mounting groove 251.

[0054] The valve body 1 is connected to the base 25 through a fastener 3. The fastener 3 can be a bolt or the like. Mounting holes are provided on both sides of the valve body 1, and the fastener 3 such as a bolt is inserted into the mounting holes and fixedly connected to the base 25, thereby fixedly mounting the valve body 1 on the base 25.

[0055] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of the present application, the patent protection scope of the present application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification based on the substantial concept of the present application, using the content recorded in the text and drawings of the specification of the present application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are included in the patent protection scope of the present application.
