Description

Relay socket

Technical field

The utility model relates to a kind of electric component, particularly a kind of relay socket.

Background technology

The pattern of transducer is numerous, but general with the most use be two lines with three-way, two lines with the load series connection.The three-way opener utmost point that mostly is is exported, and three lines are respectively the collector electrode of positive-negative power and output transistor.The NPN of transducer and PNP come according to the model of output transistor.The load of NPN is to be connected between positive supply and the collector electrode, and PNP is connected between collector electrode and the negative supply, and because transducer is that NPN type or positive-negative-positive are to change, therefore the mode of connection that is used for controlling the relay of transducer can not change, therefore the mode of connection of relay socket also is to change, be NPN formula or the PNP formula of relay socket according to setting, thus the corresponding transducer that connects NPN formula or PNP formula.This is the deficiency of existing relay socket just, and promptly a socket is only to being used to connect a kind of NPN formula or PNP formula transducer.

The utility model content

The purpose of this utility model provides a kind of relay socket that control NPN formula transducer also can be used for PNP formula transducer that both can be used to connect.

The purpose of this utility model is achieved through the following technical solutions: a kind of relay socket, include pedestal, on the upper surface of pedestal, be provided with the relay pin holes of at least one relay that is used to peg graft, be respectively equipped with control end wiring hole and load end wiring hole at the two ends of pedestal, described control end wiring hole includes anodal wiring hole, the negative pole wiring hole and with the corresponding signal end wiring hole of relay number, it is characterized in that: also be provided with on the described pedestal and the corresponding change over switch of relay number, described change over switch is a double-point double-throw switch, the moving broken ends of fractured bone of double-point double-throw switch or two contacts of movable end are connected with the positive pole and the signal end of control end respectively, two contacts of the movable end or the moving broken ends of fractured bone are connected with the negative pole and the signal end of control end respectively, and two common port contacts are connected with relay coil.

Preferred version of the present utility model is: between the positive pole of described control end and the double-point double-throw switch and the negative pole of control end and and double-point double-throw switch between all be provided with diode.

Another preferred version of the present utility model is: be connected with resistance and light-emitting diode L1 between the described diode.

A preferred version more of the present utility model is: the common port of described double-point double-throw switch also is connected to light-emitting diode L2, and this light-emitting diode L2 is in parallel with relay coil.

The beneficial effects of the utility model are: by the operation change over switch, just can make these relay socket freedom and flexibility use sensors of various types, and do not need to change this circuit, promptly relay socket can be applied to the transducer of PNP or NPN formula simultaneously, made things convenient for use, provided cost savings.

Embodiment

Now in conjunction with the accompanying drawings the utility model execution mode is further described:

As Fig. 1, shown in Figure 2, a kind of relay socket, include pedestal 1, in the relay pin holes 2 that is provided with two relays (can certainly be a relay or the relay more than two) that be used to peg graft on the upper surface of pedestal, be respectively equipped with control end wiring hole 3 and load end wiring hole 4 at the two ends of pedestal, described control end wiring hole 3 includes anodal wiring hole 31, the signal end wiring hole 33 of negative pole wiring hole 32 and corresponding with the relay number (in the diagram being two), also be provided with on the described pedestal 1 and relay number corresponding (two) change over switch 4, described change over switch 4 is a double-point double-throw switch, two contacts 41 of the movable end of double-point double-throw switch 4 are connected with the positive pole and the signal end of control end respectively, two contacts 42 of the moving broken ends of fractured bone are connected with the negative pole and the signal end of control end respectively, two common port contacts 43 are connected (two contacts that can certainly adopt the useful moving broken ends of fractured bone are connected with the positive pole and the signal end of control end respectively, and two contacts of movable end are connected with the negative pole and the signal end of control end respectively) with relay coil S.When double-point double-throw switch was in shown position (promptly Zhong Jian double-point double-throw switch S1 pushes the P end), an end of relay coil was connected with the negative pole of outside input power supply.Make the actuating of relay, must be with the other end of relay coil, promptly control signal wire 1 communicates with the positive pole of power input terminal and could constitute the loop, and this connection is brought in from control, is that high level is effective, so be referred to as PN connection (PNP) mode of connection.And middle double-point double-throw switch S1 is pushed the N end, this moment, one end of relay coil was connected with the positive pole of outside input power supply, make the actuating of relay, must be with the other end of relay coil, be that control signal wire 1 communicates with the negative pole of power input terminal and could constitute the loop, this connection is brought in from control, is that low level is effective, so be referred to as N connection (NPN) mode of connection.Promptly by the operation change over switch, just can make this relay socket freedom and flexibility use sensors of various types, and not need to change this circuit, promptly relay socket can be applied to the transducer of PNP or NPN formula simultaneously, has made things convenient for use, provides cost savings.

In the illustrated embodiment, between the positive pole of described control end and the double-point double-throw switch and the negative pole of control end and and double-point double-throw switch between be respectively equipped with diode D1, D2, it is for the rated current direction that diode D1, D2 are set, because relay must electricly all can produce induced electromotive force with dead electricity, be provided with diode and can prevent of the impact of the electric wave of power supply, thereby make performance better circuit.

In the present embodiment, between described diode D1, D2, also be connected with resistance R 1 and light-emitting diode L1, by the light-emitting diode on and off show power on or do not have the electricity two states, promptly powering on just can constitute the loop.

In the present embodiment, the common port of described double-point double-throw switch also is connected to light-emitting diode L2, and this light-emitting diode L2 is in parallel with relay coil S.

Need to prove: embodiment of the present utility model described above only illustrates, and those skilled in the art can also make numerous variations or modification to these execution modes, and do not deviate from principle of the present utility model and essence.Protection range of the present utility model is only limited by appended claims.
