first connection terminal, first PCB division board, circuit board, second PCB division board and second connecting terminal connect gradually, be provided with on the first PCB division board with the corresponding size's of first connection terminal stitch hole, first connection terminal and second connecting terminal's pin one-to-one is connected on the circuit board, be provided with on the second PCB division board with the corresponding size's of second connecting terminal dead slot and with the corresponding size's of first connection terminal stitch hole.

Further, the first connecting terminal is a WAGO connector of 737 series.

Further, the circuit board is a PCB circuit board.

Further, the second connection terminal is a DIN41612 type connection terminal.

Further, be provided with a metallization via hole on four angles of first PCB division board, circuit board, second PCB division board respectively, the metallization via hole is the fixed metal mounting hole of first PCB division board, circuit board, the fixed connection of second PCB division board zonulae occludens, fills with wire and soldering tin, realizes closely laminating fixedly.

Compared with the prior art, the utility model, it is showing the advantage and lies in:

(1) the external connection device of the control cabinet of the utility model has simple operation, convenient use and high use efficiency;

(2) the structure is simple, only the PCB needs to be added on the basis of the original connecting terminal for welding, the number of parts is small, and the manufacture and the improvement are convenient;

(3) the manufacturing, assembly and use are easy, so the cost is greatly reduced, the product can be manufactured after the design is finished, and the popularization is easy;

(4) the universality is high, and one connecting device can be suitable for testing different devices.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

With reference to fig. 1, part 1: 737 series of WAGO connectors.

Component 2: the PCB isolation board electrically isolates the component 1 from the component 3, and the isolation board is not provided with any circuit connection and only has pin holes with corresponding sizes of the component 1, so as to prevent short circuit caused by metal touch between the component 1 and the component 3.

Component 3: the pins of the 737 series WAGO connecting terminal (part 1) and the DIN41612 type connecting terminal (part 5) are connected on the PCB in a one-to-one correspondence.

Component 4: the PCB isolation board electrically isolates the component 3 from the component 5, and the PCB isolation board is provided with an empty groove with the corresponding size of the component 5 and a pin hole with the corresponding size of the component 1; the device is used for preventing the welding point on the component 3 from touching the metal surface of the case to cause short circuit when in use.

Component 5: DIN41612 type connection terminal.

The metallized through holes corresponding to the four corners of the component 2, the component 3 and the component 4 are three component tightly connected and fixed metal mounting holes, and are filled with metal wires and soldering tin to realize tight attachment and fixation.

The utility model discloses control cabinet connecting device, PCB circuit board's one end is 737 series Wago connecting terminal, the other end is DIN41612 type connecting terminal, the centre links to each other two connecting terminal pins through PCB circuit board, draw two PCB division boards (only be used for keeping apart) that do not have any circuit according to connecting terminal overall dimension and stitch size interval again, only structural dimension on the PCB division board, there is not the circuit connection, a welding point for on isolation circuit board (part 3), prevent touching or welding point and metal covering touching between the welding point.

The connecting device is used for being connected with a model 09061486901 connector on a control cabinet. Because the corresponding plug of the connector with the model number of 09061486901 in the debugging process is a needle pressing type plug, the corresponding pin needs to be pressed and connected with the contact pin in use, the operation is complex, a special needle pressing tool needs to be configured, and a special needle withdrawing device is needed to withdraw the needle after the contact pin is inserted into the connector, the operation is complex, and the cost is high; the connecting device can be directly connected with an 09061486901 connector in a plug-in manner, and in the wiring operation, the wiring can be completed only by using a straight screwdriver to perform the wire pressing operation on 737 series connecting terminals on the connecting device; the connecting device is high in universality, the working efficiency is greatly improved, and the use cost of a debugging engineer is reduced.
