Abstract

The utility model relates to an electronic device connection device, and especially relates to a PLC (programmable logic controller) connection terminal structure. A PLC connection base comprises a printed circuit board, a pin connector and a simple horn socket. The pin connector is welded and fixed on the first side of the printed circuit board. The simple horn socket is welded and fixed on the second side of the printed circuit board. A pin of the pin connector and a pin of the simple horn socket are electrically connected through a printed copper foil wire on the printed circuit board. The PLC connection base provided by the utility model can conveniently realize the fast connection of the PLC and a function board and is not limited by the space of a case.

Description

A kind of PLC Connection Block

Technical field

The utility model relates to the jockey of electronic installation, especially the structure of the splicing ear of PLC (programmable logic controller (PLC)).

Background technology

In some field of electric control, for example in water quality detection system, usually need to use PLC and be used as control core.Consulting shown in Figure 1ly, is existing common a kind of PLC.The signal connecting terminal of existing PLC is that as shown in FIG. the mode of passing through terminal screw fixed signal wire accesses mostly.Although this syndeton simple general-purpose in some checkout equipments, is subject to chassis space, the structure of this PLC link seat is not extremely to be beneficial to manual line operation.For example, in some water quality detecting devices, just can not carry out easily connection line operation, cause producing installation effectiveness low.

The utility model content

Therefore, the utility model proposes a kind of PLC Connection Block, by by means of this PLC Connection Block, other outside feature boards can be connected more easily with the universal screw terminals seat of PLC.

The utility model adopts following technical scheme to realize:

A kind of PLC Connection Block, comprise: a printed substrate, row's needle connector and a Simple oxhorn socket, described row's needle connector is fixedly welded on the first surface of printed substrate, described Simple oxhorn socket is fixedly welded on second of printed substrate, and the pin (PIN pin) of row's needle connector and the pin (PIN pin) on the Simple oxhorn socket are to be electrically connected to by the print copper tinsel cord on printed substrate.

Preferably, it is one group that the pin of described row's needle connector (PIN pin) is every 2, and between two adjacent groups, disappearance is 1.

Utilize row's needle connector of PLC Connection Block of the present utility model to be connected to PLC link seat, recycling Simple oxhorn socket is external in other outside feature boards, can realize more easily that namely PLC is connected with the quick of feature board, and not too be subject to the spatial limitation of cabinet.

Embodiment

Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.

Consult shown in Figure 2, PLC Connection Block of the present utility model, comprise: a printed substrate 1, row's needle connector 2 and a Simple oxhorn socket 3, described row's needle connector 2 is fixedly welded on the first surface of printed substrate 1, described Simple oxhorn socket 3 is fixedly welded on second of printed substrate 2, and the pin (PIN pin) of row's needle connector 2 and the pin (PIN pin) on Simple oxhorn socket 3 are to be electrically connected to by the print copper tinsel cord on printed substrate 1.

Wherein, row's needle connector 2 is in the PCB circuit board that is widely used in electronics, electrical equipment, instrument, and its effect is to be blocked in circuit between place or isolated obstructed circuit, plays the function of bridge, shoulders the task of electric current or signal transmission; Usually support the use with the row mother, consist of plate plate is connected; Or support the use with the wire harnesses terminal, consist of plate line is connected; Also can independently be used for plate is connected with plate.Simple oxhorn socket 3 is a kind of simplified structures of cattle horn socket, does not possess the buckling piece at two ends, and only locates by the breach of centre; Also a kind of signal gang socket in the PCB circuit board that is widely used in electronics, electrical equipment, instrument.

Again consult shown in Figure 1, the screw junction block of PLC have upper and lower 2 row.Therefore, can be for the PLC Connection Block of first, second embodiment of quantity different designs as shown in Fig. 3 a and Fig. 3 b of the connecting pin of the screw junction block of PLC.These two embodiment are only that the pin number of row's needle connector 2 and Simple oxhorn socket 3 is distinguished to some extent.

Because the spacing of each screw tie point of the screw junction block of as shown in Figure 1 PLC is spacing greater than each pin (PIN pin) in row's needle connector 2 of the PLC Connection Block of first, second embodiment.Therefore consult shown in Fig. 4 a and Fig. 4 b, for coupling that can be good, preferred, it is one group that the pin of described row's needle connector 2 (PIN pin) is every 2, and between two adjacent groups, disappearance is 1.Certainly, end to end pin (PIN pin) can be only 1.

Consult shown in Figure 5, the schematic diagram that exactly the link seat of the PLC Connection Block of the second embodiment and PLC is connected and fixed.The pin of every group in row's needle connector 2 of embodiment (PIN pin) is inserted in each screw link of PLC, then screws and to complete and being connected of PLC.And then an end that two ends is had the winding displacement of Simple oxhorn plug is inserted in the Simple oxhorn socket 3 of this embodiment, and the other end inserts in the Simple oxhorn socket on the external function plate; Can realize that PLC docks with the reliable of feature board.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection range of the present utility model.

Claims
