Description
Technical Field
The utility model relates to the technical field of electrical connection, in particular to a terminal strip module.
Background
The terminal block means an insulating member carrying a plurality or a plurality of sets of terminal assemblies insulated from each other and used for fixing the supporting member. The terminal strip is used for connecting the IO substrate and the controlled substrate together, so that signal transmission is carried out between the IO substrate and the controlled substrate. Through the terminal strip for the construction is more convenient, and the wiring is more pleasing to the eye, and it is easier to maintain.
In the prior art, the types of IO substrates vary. The terminal strip type matched with the IO substrate with the type of JANCD-AIO ≡ -E is TIFS553YS. Specifically, JANCD-AIO ≡ -E has two seed types, namely JANCD-AIO01-E, JANCD-AIO02-E. The triode connected with JANCD-AIO01-E is NPN, and the triode connected with JANCD-AIO02-E is PNP. However, the TIFS553YS can only play a role of connection, which results in that the controlled substrate has a slightly different circuit composition for adapting to JANCD-AIO ≡ -E. This results in the need to provide two controlled substrates during actual operation, which is relatively costly on the one hand and is prone to problems such as connection failure due to model mismatch on the other hand. Meanwhile, the difference of the models brings unnecessary trouble to the later maintenance.

Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
A terminal block module, comprising: a plug interface 1, an external terminal interface 2, a photoelectric coupler 3 and a relay 4. The plug interface 1 is a 40PIN plug interface matched with a JANCD-AIO ≡ -E type IO substrate (hereinafter referred to as IO substrate). The plug interface 1 includes an input plug interface 11 and an output plug interface 12. The input plug interface 11 counts twelve pins, and the output plug interface 12 counts twelve pins. The other remaining PINs of the 40PIN plug interface are used for connecting the basic components for normal operation of the IO substrate, and are not described here again. The external terminal interface 2 includes an input external terminal interface 21 and an output external terminal interface 22. The total number of the input external terminal interfaces 21 is twelve, and the total number of the output external terminal interfaces 22 is twelve.
The photocoupler 3 employs an ELQ3H4 photocoupler 3. The photocoupler 3 is provided between the plug interface 1 and the external terminal interface 2. The number of photocouplers 3 is three. The input end of the same photocoupler 3 is electrically connected with four input external terminal interfaces 21. The output of the same photocoupler 3 is electrically connected to four input plug interfaces 11. Thereby, the twelve pin input plug interface 11 and the twelve input external terminal interface 21 can be all connected to the photocoupler 3.
Relay 4 employs an APAN3124 type relay 4. The input of the relay 4 is electrically connected to the output plug interface 12. The output terminal of the relay 4 is electrically connected to the output external terminal interface 22. Wherein the number of relays 4 is twelve. The relays 4 are in one-to-one correspondence with the output plug interfaces 12 and in one-to-one correspondence with the output external terminal interfaces 22. Thereby, the twelve-pin output plug interface 12 and the twelve-pin output external terminal interface 22 can be all connected to the relay 4.
In practical application, the utility model is electrically connected with the IO substrate through the plug interface 1. The utility model is electrically connected with the controlled substrate through the external terminal interface 2. When the controlled substrate outputs signals, the signals enter through the input external terminal interface 21, pass through the photoelectric coupler 3 and then enter the IO substrate through the input plug interface 11. The IO substrate performs corresponding processing according to the input signal, and then outputs a corresponding signal, and the output signal is output through the output plug interface 12 and then is output to the controlled substrate through the relay 4 by the output external terminal interface 22.
In the foregoing process, based on the photocoupler 3, the single-pass channel of the original TIFS553YS terminal strip (the specific structure is shown in fig. 2) is converted into the double-pass channel of the present utility model, so that the signal input by the controlled substrate can be preprocessed by the photocoupler 3. Therefore, the controlled substrate can be adapted to two different models of JANCD-AIO ∈ -E, and the controlled substrate does not need to be selected in actual operation. Therefore, connection faults caused by model selection errors are effectively avoided, and on the other hand, the cost is reduced to a certain extent. Meanwhile, the post-maintenance is also greatly facilitated.
Secondly, utilize photocoupler 3, keep apart IO base plate and controlled base plate at the input, when controlled base plate has the damage risk because of unusual, photocoupler 3 can keep apart risk and IO base plate, avoids causing IO base plate damage because of the risk transfer to the IO base plate.
On the other hand, the utility model can also be directly connected with DC24V and switching value sensors based on the self double-pass characteristic.
When the IO substrate outputs signals outwards, the relay 4 is utilized to control the conduction between the output plug interface 12 and the output external terminal interface 22, so that the IO substrate is isolated from the controlled substrate at the output end, and the damage risk of the controlled substrate is prevented from being transmitted to the IO substrate by the output end, and the IO substrate is prevented from being damaged. Meanwhile, the load capacity of the IO substrate is improved by utilizing the physical characteristics of the relay 4.
Meanwhile, by utilizing the isolation effect of the photoelectric coupler 3 and the relay 4, the utility model is also provided with an input end power interface (shown as a COMIN port IN the figure 1) and an output end power interface (shown as a COMOUT port IN the figure 1). The utility model can be connected with the external DC24V power supply at the input end and the output end respectively by utilizing the input end power supply interface and the output end power supply interface, thereby directly connecting the power supply required by operation on the controlled substrate when the controlled substrate has no power supply or can not provide power supply.
