The first terminal 1 is disposed opposite to the second terminal 2, and the display lamp set 4 is disposed in front of the first terminal 1 and is arranged in parallel with the first terminal 1 in a row.
The first terminal 1 and the second terminal 2 are substantially identical connection terminals, and in this embodiment, each of the first terminal 1 and the second terminal 2 includes 5 connection holes 11. Wherein the first terminal 1 is defined as an input terminal and the second terminal 2 is defined as an output terminal. When the circuit is not connected, the first terminal 1 and the second terminal 2 may be replaced with each other. However, since the position of the signal display circuit on the substrate 3 is already fixed, the connection terminal closest to the display lamp group 4 is often defined as the first terminal 1 (input terminal), and the second terminal 2 is disposed opposite to the first terminal 1.
The miniature terminal assembly structure shown in fig. 1 includes 6 indicator lights, but the signal display circuit shown in fig. 2 includes 4 indicator lights. The user can customize 4 display lamps on the signal display circuit on the miniature terminal assembly shown in fig. 1, and the other 2 display lamps are used for making reserved indication lamps.
The first terminal 1 and the second terminal 2 each include 5 wiring holes 11 and 5 fixing holes 12. Each of the wire connection holes 11 is matched with each of the fixing holes 12. The sensor and the upper computer equipment are connected into the wiring holes 11 of the first terminal 1 and the second terminal 2 through signal wires, and a user fixes the signal wires in the wiring holes 11 by placing screws in the fixing holes 12. In order to distinguish the multipath wiring holes 11 of the first terminal 1 and the second terminal 2, correspondingly, a first wire inlet hole, a second wire inlet hole, a third wire inlet hole, a fourth wire inlet hole and a fifth wire inlet hole are sequentially arranged on the first terminal 1 from left to right, and a first wire outlet hole, a second wire outlet hole, a third wire outlet hole, a fourth wire outlet hole and a fifth wire outlet hole are sequentially arranged on the second terminal 2 from left to right.
The first terminal 1 and the second terminal 2 are each provided on the substrate 3, and each wiring hole 11 is connected to a printed circuit on the substrate 3. The first terminal 1 is connected with the sensor through a signal wire, and the second terminal 2 is connected with the upper computer equipment through a signal wire, namely the upper computer equipment and the sensor perform data transmission through the first terminal 1 and the second terminal 2. The sensor is connected to the first terminal 1 through a signal wire, so that the sensor can be connected with the miniature terminal assembly; the upper computer equipment is connected with the second terminal 2 through a signal wire, and the miniature terminal assembly can be connected with the upper computer equipment.
The substrate 3 is also provided with a signal display circuit, and the signal display circuit is printed on the substrate 3 through a printed circuit and is connected with the display lamp set 4. The sensor is connected to the micro terminal assembly through a signal line, electrically connected to the display lamp set 4, and indicates the state of the sensor by turning on/off the display lamp set 4. That is, the micro terminal assembly only realizes the wiring installation of the sensor access device, and cannot realize the change of the function thereof.
As shown in fig. 2, the signal display circuit includes a first transistor Q1, a second transistor Q2, and a third transistor Q3; the display lamp set 4 includes a first diode D1, a second diode D2, a third diode D3 and a fourth diode D4. The positive electrode of the first diode D1 is connected with the collectors of the first transistor Q1, the second transistor Q2 and the third transistor Q3; the anode of the second diode D2 is connected with the emitter of the first transistor Q1; the anode of the third diode D3 is connected with the emitter of the second transistor Q2; the anode of the fourth diode D4 is connected with the emitter of the third transistor Q3; the cathodes of the first diode D1, the second diode D2, the third diode D3 and the fourth diode D4 are all grounded. Further, the base electrode of the first transistor Q1 is connected between the third wire inlet hole and the third wire outlet hole; the base electrode of the second transistor Q2 is connected between the fifth wire inlet hole and the fifth wire outlet hole; the base electrode of the third transistor Q3 is connected between the fourth wire inlet hole and the fourth wire outlet hole. The first wire inlet hole and the first wire outlet hole are grounded; the positive pole of first diode D1 is connected to between second inlet wire hole and the second wire hole, and the positive pole of first diode D1, second inlet wire hole, second wire hole and power are connected.
That is, the power supply and the emitter of each triode are connected with a diode, and the collector of each triode is connected with the power supply. When the power supply is normal, and the sensor is connected to the first terminal 1 and the second terminal 2, if the wiring is correct, the power supply connected to the first diode D1 through the second wire inlet hole and the second wire outlet hole is powered on, and the working state is normally bright. Conversely, when the sensor is connected to the first terminal 1 and the second terminal 2, the wiring is wrong/loose, and the power supply is not powered on, the first diode D1 is turned off.
When the sensor works normally, a plurality of signal wires connected with the sensor are distributed correctly, and the sensor is communicated with the upper computer equipment in a normal connection way. At this time, the sensor switches the bases of the first transistor Q1, the third transistor Q3 and the second transistor Q2 into high level through the printed circuit line on the substrate 3, so that the first transistor Q1, the third transistor Q3 and the second transistor Q2 are in a conducting state, and at this time, the second diode D2, the third diode D3 and the fourth diode D4 are in a normally-on state.
Since the sensor is connected with the display lamp set 4 through the plurality of signal lines, when the sensor is debugged, if any one of the second diode D2, the third diode D3 and the fourth diode D4 is in an off state under the condition that the first diode D1 is normally on, an error occurs when the sensor is debugged according to the corresponding signal. If more than one of the second diode D2, the third diode D3 and the fourth diode D4 is turned off when the first diode D1 is normally on, an error occurs in the signal line group connection to which the sensor is connected.
Further, the substrate 3 of the miniature terminal assembly has a length of 13.1mm, a width of 20.6mm and a height of 12mm. Maximum length and width and maximum height of the entire miniature terminal assembly. According to the length, width and height of the miniature terminal assembly, the miniature terminal assembly is more suitable for precision equipment with compact space. The distance between adjacent wiring holes 11 of the first terminal 1 and the second terminal 2 is 2.5mm, the current of the terminal access is larger than 1A, the signal current requirement is met, the line diameter of the signal line is not more than 0.3mm, the state indication of the visual indicator lamp is carried out on part of signal change of the sensor, the space is compact, the mounting position of the sensor is limited, and the self-contained indicator lamp is not easy to observe. The signal state is transferred to the wiring terminal strip, so that the identification and analysis of debugging personnel can be more intuitively and conveniently realized. A cable locking structure is arranged between the first terminal 1 and the second terminal 2 and used for locking and fixing wiring of a plurality of signal wires accessed by the sensor, so that firm and reliable wiring of the wire harness is ensured. It should be noted that, in the drawings, no cable locking structure is indicated, and the cable locking structure on the market can be fixed in the waist groove between the first terminal 1 and the second terminal 2, or the signal wires connected with the sensor are bundled by the strapping tape, so as to realize wiring carding and fixing. Because the position of the sensor in the equipment is fixed, the installation hole site can be reserved according to the position of the sensor and in a fixed mode, the sensor installation and wiring separation installation can be easily realized, and the wiring method is standardized and is not easy to be wrong. The debugging stage has a state indicating function, so that the normal state or the fault state of the sensor can be easily identified. In the after-sale stage, the cable and the functional components are installed separately, so that the on-site maintenance is easy to realize.
The embodiment is a specific example only and does not suggest one such implementation of the utility model.
The foregoing is only a preferred embodiment of the utility model, and it will be appreciated by those skilled in the art that various changes in the features and embodiments may be made and equivalents may be substituted without departing from the spirit and scope of the utility model. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the utility model without departing from the essential scope thereof. Therefore, it is intended that the utility model not be limited to the particular embodiment disclosed, but that the utility model will include all embodiments falling within the scope of the appended claims.
