Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
The terminals are common elements for connecting electrical lines, and mainly function as electrical connections and signal transmission between devices and assemblies, assemblies and cabinets, and systems and subsystems. And the wiring terminal can keep the system and the system from signal distortion and energy loss change, so the wiring terminal is widely applied to the transmission of long-distance signals.
Generally, the two terminals are not conductively connected with each other, so that an external wire is required to electrically connect the two terminals when the two terminals are connected. For example, in the project of a gas suspension series frequency conversion cabinet, the connecting terminals are used for transmitting signals of the frequency conversion cabinet and the external control box, and the connecting terminals on the frequency conversion cabinet and the connecting terminals on the external control box are connected by using the wires, so that the control signal butt joint of the frequency conversion cabinet and the external control box is realized. In practical application, the frequency conversion cabinet can be connected with the external control box only when the test of the whole machine is carried out, but the connection with the external control box is not needed when other tests and debugging are carried out, so that the wiring terminal of the external control box connected to the frequency conversion cabinet does not need to be connected with a wire. However, at this time, the main board in the inverter cabinet may erroneously read the emergency stop signal, which causes the inverter cabinet to report protection and trip the circuit breaker as long as the inverter cabinet is powered on, and thus the inverter cabinet cannot be normally powered on to operate. In order to solve the problem in the prior art, the wiring terminal directly connecting the frequency conversion cabinet with the external control box is communicated by a wire, so that the main board cannot mistakenly read an emergency stop signal when the frequency conversion cabinet is electrified. However, the method of using the external plug wire connection leads to more complicated wire connection in the whole experimental process, and the connection of the wire needs to be changed along with different test items in the test process, so that the wiring fault is easy to occur in the wiring process and the debugging process, and the fault is not easy to be checked once the fault occurs.
Therefore, in order to solve the technical problem that the way of connecting the external plug wire with the two non-conductive connecting terminals is easy to make mistakes in the prior art, the invention provides a connecting device, which comprises:
each wiring terminal is provided with a plurality of wiring holes with conductive pieces inside, and all the conductive pieces on each wiring terminal are connected in series and conducted. If only one wiring terminal is needed to be connected with two electrical appliances, only one wiring hole and one electrical appliance on the wiring terminal are needed to be connected through a conducting wire, and the other wiring hole and the other electrical appliance on the wiring terminal are needed to be connected through the other conducting wire.
The connecting piece is characterized by further comprising a connecting piece electrically connected with the two conductive pieces, the two conductive pieces connected with the connecting piece are respectively positioned on the two wiring terminals, so that the two non-conductive wiring terminals are electrically connected without using an external plug-in wire mode, the connecting piece can be separated from the conductive pieces when wires are inserted into wiring holes corresponding to the conductive pieces connected with the connecting piece, the connecting piece cannot influence the use of the external plug-in wires of the wiring terminals, and the two non-conductive wiring terminals can be electrically connected without using the external plug-in wires.
In summary, the connection device provided by the invention enables the two non-conductive connection terminals to be electrically connected without the need of externally plugging wires by arranging the connection piece, and the connection piece can be disconnected with the two connection terminals under the condition that the wires are externally plugged in the corresponding connection holes, so that the use of the externally plugging wires of the connection terminals is not influenced. Therefore, the wiring device provided by the invention can simplify the connection mode and also provide a plurality of using modes for users.
Further, the conductive piece comprises a butting part and a contact part, the butting part is butted with the shell of the wiring terminal when no wire is inserted into the wiring hole corresponding to the conductive piece, the contact part is positioned below the wiring hole corresponding to the conductive piece, and the contact part is electrically contacted with the wire and simultaneously separated from the shell when the wire is inserted into the wiring hole corresponding to the conductive piece.
Furthermore, two ends of the connecting piece are respectively fixed on the shells of the two wiring terminals, and the end part of the connecting piece is clamped between the shells and the butting part of the conductive piece. When no wire is inserted into the wiring hole corresponding to the conductive piece connected by the connecting piece, the butting part of the conductive piece and the shell are butted, so that the connecting piece is in electric contact with the butting part of the conductive piece, the connecting piece realizes the electric connection between the conductive pieces on the two wiring terminals, and the electric connection between the two wiring terminals is realized. When the wires are inserted into the wiring holes corresponding to the conductive pieces connected by the connecting piece, the abutting parts of the conductive pieces are separated from the shell at the moment, so that the connecting piece is not in contact with the abutting parts of the conductive pieces, and the connecting wire is disconnected from the two wiring terminals.
The principles and structures of the present invention are described in detail below with reference to the drawings and the embodiments.
First, a wiring device in the related art is described with reference to fig. 1 and 5. Specifically, as shown in fig. 1, the wiring device includes two wiring terminals, i.e., a first wiring terminal 1 and a second wiring terminal 2, each wiring terminal is provided with two wiring holes connected in series, the two wiring terminals are arranged in two rows in close proximity to each other, and the two wiring terminals cannot be electrically connected without inserting a wire. Wherein, first binding post 1 includes first wiring hole 11, second wiring hole 12, and second binding post 2 includes third wiring hole 21, fourth wiring hole 22, and first wiring hole 11 and third wiring hole 21 are on a straight line, and second wiring hole 12, fourth wiring hole 22 are on another straight line, and first wiring hole 11, second wiring hole 12, third wiring hole 21 and fourth wiring hole 22 enclose into a square. For example, as shown in fig. 5, the wiring device is specifically used in the debugging process of the whole of the inverter cabinet and the external control box or the independent debugging process of the inverter cabinet. The frequency conversion cabinet 3 is provided with a main board, a 24V power supply and a wiring device, wherein the main board is connected with the first wiring hole 11 through an external plug wire, the 24V power supply is connected with the third wiring hole 21 through an external plug wire, a first emergency stop button 5 is arranged between the main board and the first wiring hole 11, the first emergency stop button 5 is closed under a normal state, and once the first emergency stop button 5 is pressed, the first emergency stop button is in an off state. Similarly, the external control box 4 is provided with a fifth wiring hole 41 and a sixth wiring hole 42 which are not connected with each other, a second emergency stop button 9 is also arranged between the fifth wiring hole 41 and the sixth wiring hole 42, the second emergency stop button 9 is closed in a normal state, and once the second emergency stop button 9 is pressed, the second emergency stop button 9 is in an open state. When the frequency conversion cabinet 3 and the external control box 4 are integrally debugged, the fifth wiring hole 41 is connected with the second wiring hole 12 through an external plug wire, and the sixth wiring hole 42 is connected with the fourth wiring hole 22 through an external plug wire, so that the frequency conversion cabinet 3 and the external control box 4 are electrically connected. If the mainboard reads a high level signal in the debugging process, the first emergency stop button 5 and the second emergency stop button 9 are both in a closed state, the circuit breaker does not trip, and the frequency conversion cabinet 3 works normally; if the main board reads a low level in the debugging process, the first emergency stop button 5 and/or the second emergency stop button 9 are/is in an off state at the moment, the circuit breaker trips, and the frequency conversion cabinet 3 stops running. When the frequency conversion cabinet 3 is debugged independently, no lead is connected between the fifth wiring hole 41 and the third wiring hole 21, and no lead is connected between the sixth wiring hole 42 and the fourth wiring hole 22. At this moment, be nonconducting between first binding post 1 and the second binding post 2, so the mainboard can read the low level this moment, and the circuit breaker can trip this moment, frequency conversion cabinet bring to rest, therefore the frequency conversion cabinet can report the mistake all the time when the debugging. In order to solve the problem, an external plug wire is required to connect the second wiring hole 12 and the fourth wiring hole 22 in the prior art, so that the main board can normally read the high level, and the frequency conversion cabinet can be debugged in normal operation. However, the debugging is software debugging, but not all software debugging personnel understand the principle of the electric appliance circuit, so that in the actual debugging process, the software debugging personnel can not understand the internal structure and the circuit principle of the wiring terminal, which causes the frequency conversion cabinet to always report errors in the independent debugging process, and the frequency conversion cabinet cannot be normally debugged.
Therefore, the invention is modified based on the existing wiring device to avoid the reoccurrence of the problem. As shown in fig. 2, the present invention electrically connects the first wiring hole 11 and the third wiring hole 21 and electrically connects the second wiring hole 12 and the fourth wiring hole 22 from the inside using the connector 7 passing through the housings of the first wiring terminal 1 and the second wiring terminal 2. Further, the connector is electrically connected to the first and third wiring holes 11 and 21 when no lead is inserted into the holes, and is electrically disconnected when a lead is inserted into the hole 11 and/or 21.
Specifically, as shown in fig. 3 and 4, a first wiring hole 11 and a second wiring hole 12 are provided at an interval on the housing of the first wiring terminal 1, wherein communication grooves are provided at the bottoms of the first wiring hole 11 and the second wiring hole 12, and the communication grooves communicate the first wiring hole 11 with the second wiring hole 12. And a conductive piece 6 is respectively arranged in the first wiring hole 11 and the second wiring hole 12, and a whole conductor is arranged in the communication groove, the first wiring hole 11 and the second wiring hole 12 and is attached to the inner wall of the shell. Specifically, the first wiring hole 11 and the second wiring hole 12 include a cylindrical portion to be inserted into a wire and an irregular groove portion to receive a conductive member, and the conductive member 6 is an a-shaped spring. When the a-shaped conductive piece 6 is placed in the first wiring hole 11 and the second wiring hole 12, the circular ring parts of the a-shaped conductive piece 6 can be tightly attached and extruded with the conductor and the inner wall of the shell, so that the a-shaped conductive piece 6 is fixed in the first wiring hole 11 and the second wiring hole 12, the two conductive pieces are connected in series and conducted through the conductor, and the part, pressed and butted with the shell, of the a-shaped conductive piece 6 is the butting part 61. The tail portions of the conductive members 6 of the letter a are located right below the cylindrical portions of the first and second wiring holes 11 and 12 into which the wires are inserted. When the wires are inserted into the first and second wiring holes 11 and 12, the tail portion of the a-shaped conductive member 6 is in electrical contact with the wires, and the portion of the a-shaped conductive member 6 in contact with the wires is a contact portion 62. Meanwhile, the tail portion of the conductive member 6 shaped as a is forced to be deformed downward, so that the butting portion 61 is forced to be separated from the inner wall of the case.
Similarly, the structure of the second connection terminal 2 is the same as that of the first connection terminal 1.
Further, the connecting member passes through the housings of the first connection terminal 1 and the second connection terminal 2 to connect the conductive members 6 in the first wiring hole 11 and the third wiring hole 21, thereby achieving electrical conduction between the first wiring hole 11 and the second wiring hole 12, and further achieving electrical connection between the first connection terminal 1 and the second connection terminal 2. The connecting member 7 is a conductor, one end of the connecting member 7 is fixed on the inner wall of the housing of the first connection terminal 1, and the end portion is clamped between the abutting portion 61 and the housing, the other end of the connecting member 7 is fixed on the inner wall of the housing of the second connection terminal 2, and similarly, the end portion is also clamped between the abutting portion 61 and the housing. As can be seen from the specific structures inside the first connection terminal 1 and the second connection terminal 2 and the positional relationship of the connection member 7, when no wire is inserted into the first connection hole 11 and the third connection hole 21, the abutting portion 61 of the conductive member 6 in the first connection hole 11 and the third connection hole 21 is pressed against the housing, and the connection member 7 is sandwiched between the abutting portion 61 and the housing, so that both ends of the connection member 7 are in contact with the conductive members 6 in the first connection hole 11 and the third connection hole 21, respectively, and thus the first connection hole 11 and the third connection hole 21 are electrically connected. When a wire is inserted into the first wiring hole 11 and/or the third wiring hole 21, the abutting portion 61 of the conductive member 6 in the first wiring hole 11 and/or the third wiring hole 21 is separated from the housing by a force, and the connecting member is separated from the conductive member 6 in the first wiring hole 11 and/or the third wiring hole 21, so that the first wiring hole 11 and the third wiring hole 21 are not electrically connected.
Similarly, the second wiring hole 12 and the fourth wiring hole 22 are also electrically conducted through the connection member 7.
Therefore, as shown in fig. 5 and 6, the wiring device proposed by the present invention does not have the problems of the prior art when it is used in the debugging process of the whole of the inverter cabinet and the external control box or in the separate debugging process of the inverter cabinet. When the wiring device is used in the whole debugging process of the frequency conversion cabinet and the external control box, the connection mode of the first wiring hole 11, the second wiring hole 12, the third wiring hole 21 and the fourth wiring hole 22 is unchanged, at the moment, because wires are inserted in the first wiring hole 11, the second wiring hole 12, the third wiring hole 21 and the fourth wiring hole 22, the connecting piece 7 and the conductive piece 6 are separated, the internal connection condition of the whole wiring device is the same as that in the prior art, and the whole debugging process does not need to be changed. When the wiring device is used in the single debugging process of the frequency conversion cabinet, after the wires on the second wiring hole 12 and the fourth wiring hole 22 are pulled out, the connecting piece 7 can realize the electric conduction between the second wiring hole 12 and the fourth wiring hole 22, and the connecting piece 7 can not realize the electric conduction between the first wiring hole 11 and the third wiring hole 21 because the wires are externally inserted. Therefore, normal operation can be carried out without connecting the fourth wiring hole 22 and the second wiring hole 12 with the frequency conversion cabinet by using an external plug-in wire, and software debugging personnel can directly carry out independent debugging on the frequency conversion cabinet after wire pulling, so that the debugging process is greatly simplified, and the possibility of debugging faults is reduced.
Furthermore, a jack is further arranged on the shell of the wiring terminal and located right above the jacking portion of the conductive piece, and when a wire is inserted into the wiring hole, a tool can be used for inserting the jack to assist the jacking portion to be separated from the shell.
In this embodiment, the number of the connection terminals included in the connection device is not limited, and the number of the connection holes on each connection terminal is also not limited. In addition, the specific shape of the conductive member is not limited.
In conclusion, the wiring device greatly simplifies the connection between the electric appliances and reduces the possibility of connection faults. The wiring device provided by the invention can be flexibly used, can be normally used when a lead is inserted outside the wiring hole, and can realize the electric conduction between the two wiring holes when the lead is not inserted outside the wiring hole.
The invention also proposes an apparatus using the wiring device proposed above, which comprises a frequency conversion cabinet.
