In preferred embodiment, slit on the every piece of pcb board gap distributions such as uniformly.Certainly, implementation still further It, can be according to the fixing clearance of spatial position and circuit components on pcb board, the distributed quantity of reasonable arrangement slit in example The position and.

In order to reduce cost, the rib is the identical board making of pcb board.

In optional embodiment, input terminal is identical as the quantity of output terminal, realizes the road the N input and output of 1:1.

Preferably, it between three pcb boards, is electrically connected two-by-two by contact pin-needle stand, realizes power supply and data Transmission.

Disclosed in other in embodiment, the second aspect of the utility model also propose a kind of multichannel input and output after The pcb board mounting structure of electric appliance, including at least four pieces of pcb boards, are disposed with extension pcb board, PCB top plate, PCB from top to bottom Intermediate plate and PCB bottom plate, PCB bottom plate can be engaged to casing of relay bottom；

Wherein, it is provided with the road N input terminal on PCB bottom plate, is respectively arranged with correspondence on extension pcb board and PCB top plate The road N relay unit and output terminal, and: the PCB top plate and PCB intermediate plate are located at the marginal position setting of the same side There is multiple groups slit, one has been removably inserted into each group of slit and has run through PCB top plate, PCB intermediate plate rib, each rib Upper end abuts extension pcb board, and the lower end of rib abuts PCB bottom plate；

It between four pcb boards, is electrically connected two-by-two by contact pin-needle stand, realizes power supply and data transmission.

In scheme as the aforementioned, the support to all PCB is on the one hand realized by rib-slit cooperation, reduce PCB by Deformation caused by self weight and the external power applied, on the other hand the electric connection mode hanging by the bridge-type between each plate, real Now convenient installation and electric signal transmitting.

Preferably, clearance fit between the rib and slit.Position of the slit on pcb board and input terminal, Output terminal is located at the same side.

It is more preferred, slit on the every piece of pcb board gap distributions such as uniformly.

It should be appreciated that as long as aforementioned concepts and all combinations additionally conceived described in greater detail below are at this It can be viewed as a part of the utility model theme of the disclosure in the case that the design of sample is not conflicting.In addition, being wanted All combinations of the theme of protection are asked to be considered as a part of the utility model theme of the disclosure.

The foregoing and other side of the utility model introduction can be more fully appreciated from the following description in conjunction with attached drawing Face, embodiment and feature.The features and/or benefits of other additional aspects such as illustrative embodiments of the utility model To be obvious in the following description, or will be learnt in the practice by the specific embodiment instructed according to the utility model.

Detailed description of the invention

Fig. 1 is the schematic diagram of the pcb board mounting structure of the multichannel input and output relay of the utility model.

Specific embodiment

In order to know more about the technology contents of the utility model, spy lifts specific embodiment and institute's accompanying drawings is cooperated to be described as follows.

It is described with reference to the various aspects of the utility model in the disclosure, shown in the drawings of the implementation of many explanations Example.It is not intended to cover all aspects of the utility model for embodiment of the disclosure.It should be appreciated that a variety of structures presented hereinbefore Think and embodiment, and those of describe in more detail below design and embodiment can in many ways in any one Implement, this is because conception and embodiment disclosed in the utility model are not limited to any embodiment.In addition, this is practical Novel disclosed some aspects can be used alone, or with it is disclosed by the utility model it is otherwise it is any it is appropriately combined come It uses.

As shown in connection with fig. 1, a kind of pcb board mounting structure of multichannel input and output relay, including three blocks of PCB plates, respectively Are as follows: it is arranged for being engaged to the PCB bottom plate 1 of casing of relay bottom, the PCB top plate 2 by compressing at the top of relay is set And the PCB intermediate plate 3 between the top plate and bottom plate is set.Power circuit 31 and controller are installed on PCB intermediate plate 3 Circuit 32.
