Description

Technical Field

[0001] The utility model belongs to the field of elevator control cabinets, and in particular relates to a UCMP testing and bypass protection device in an elevator control cabinet. Background Art

[0002] The bypass protection device in the existing elevator control cabinet includes a P1 socket, a P2 socket and a P plug-in with a short-circuit. When the P plug-in is inserted into the P1 socket, the safety circuit of the control cabinet is connected and the elevator is in normal operation. When the P plug-in is inserted into the P2 socket, the safety circuit is disconnected and the elevator is in maintenance. Both the P1 socket and the P2 socket are rail-type wiring terminals, which require a fixed rail in the control cabinet as a card slot. After being installed on the rail, it is not easy to wire because the control cabinet is in a flat state during wiring and there are other components and wire slots blocking the line of sight, that is, it is not easy to connect the P1 socket and the P2 socket to the control circuit of the control cabinet.

[0003] The UCMP test device in the existing elevator control cabinet includes a P3 socket and a P3 test plug-in with a short-circuit that match each other. The UCMP test device and the bypass protection device are located in different positions in the control cabinet, and the sockets and plug-ins in the UCMP test device have the same specifications as those on other nearby components, which is not easy for on-site personnel to distinguish and find, and is not convenient for control cabinet assembly.

[0004] The above sockets used in the control cabinet have a wavy inner wall on one side of the socket, and the side of the plug-in end of the matching plug-in is also wavy, which is to ensure the correct insertion direction. At the same time, there are protrusions on the plug-in, which are mainly used to integrate a snap mechanism for plug-in wiring, such as the plug-in in the KF2EDGK series terminal block. Utility Model Content

[0005] The purpose of the utility model is to provide a UCMP testing and bypass protection device.

[0006] The utility model has the advantage of being easy to assemble the control cabinet.

[0007] The technical scheme of the utility model is as follows: a UCMP test and bypass protection device comprises a circuit board, a P1 socket, a P2 socket, a P3 socket, a J1 socket, a J2 socket and a J3 socket are welded on the front of the circuit, the socket of the P1 socket, the socket of the P2 socket and the socket of the P3 socket are all perpendicular to the circuit board, the socket of the J1 socket, the socket of the J2 socket and the socket of the J3 socket are all parallel to the circuit board, the P1 socket or the P2 socket is connected with a P plug-in, the P3 socket is connected with a P3 test plug-in, the J1 socket is connected with a J1 plug-in, the J2 socket is connected with a J2 plug-in, the J3 socket is connected with a J3 plug-in, the P1 socket is connected to the J1 socket through the circuit board, the P2 socket is connected to the J2 socket through the circuit board, and the P3 socket is connected to the J3 socket through the circuit board.

[0008] In the aforementioned UCMP test and bypass protection device, the P1 socket and the P2 socket are arranged side by side, and the socket direction of the P1 socket is opposite to the socket direction of the P2 socket, so that when the P plug is inserted into the P1 socket, the protrusion of the P plug blocks the socket of the P2 socket, and when the P plug is inserted into the P2 socket, the protrusion of the P plug blocks the socket of the P1 socket.

[0009] In the aforementioned UCMP test and bypass protection device, the J1 socket, J2 socket and J3 socket are all connected to the outer edge of the circuit board, and the sockets of the J1 socket, the J2 socket and the J3 socket are all extended out of the outside of the circuit board.

[0010] In the aforementioned UCMP test and bypass protection device, the circuit board is square, the four corners of the circuit board are rounded, and mounting holes are provided at the four corners of the circuit board.

[0011] Compared with the prior art, the utility model integrates the existing bypass protection device and the UCMP test device on the same circuit board, which reduces the volume and saves the internal layout space requirements of the control cabinet. It is also convenient for on-site personnel to distinguish and find, and is convenient for control cabinet assembly. On the basis of retaining the original three sockets (P1, P2, P3), three new sockets (J1, J2, J3) are added. The newly added sockets (J1, J2, J3) are respectively connected to the original sockets (P1, P2, P3) through the circuit board. The newly added sockets (J1, J2, J3) have plug-ins (J1, J2, J3). When the original sockets (P1, P2, P3) are connected to the control circuit of the control cabinet, it is only necessary to connect the plug-ins (J1, J2, J3) to the control circuit. The plug-ins (J1, J2, J3) can be unplugged when wiring, and wiring can be carried out outside the control cabinet to avoid being blocked by other components, making wiring convenient, and can be plugged back after wiring, which is convenient for control cabinet assembly. Since the plug-ins (J1, J2, J3) are all outside the circuit board, a large grasping space can be formed on the plug-ins (J1, J2, J3), which is not interfered by the circuit board, is easy to plug and unplug, and is convenient for control cabinet assembly. Since the P1 socket and the P2 socket are arranged side by side and the sockets face opposite directions, a mutually exclusive space is formed on the P1 socket and the P2 socket. When the P plug-in is inserted into any socket of the bypass protection device, the other socket cannot be inserted by any plug-in, avoiding misassembly, which is also convenient for control cabinet assembly.

[0012] Therefore, the utility model has the advantage of being easy to assemble the control cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0019] Embodiment. A UCMP test and bypass protection device, such as Figure 1 and Figure 2 As shown, it includes a circuit board 40 , which is square in shape. The four corners of the circuit board 40 are all rounded, and mounting holes 51 are provided at the four corners of the circuit board 40 .

[0020] A P1 socket 41 , a P2 socket 42 , a P3 socket 43 , a J1 socket 44 , a J2 socket 45 and a J3 socket 46 are soldered on the front side of the circuit.

[0021] The sockets of the P1 socket 41, the P2 socket 42 and the P3 socket 43 are all perpendicular to the circuit board 40, the sockets of the J1 socket 44, the J2 socket 45 and the J3 socket 46 are all parallel to the circuit board 40, and the P1 socket 41 or the P2 socket 42 is connected with a P plug-in ( Figure 1 Omitted), P3 socket 43 is connected to a P3 test plug-in ( Figure 1 ), a J1 plug-in 48 is connected to the J1 socket 44, a J2 plug-in 49 is connected to the J2 socket 45, and a J3 plug-in 50 is connected to the J3 socket 46.

[0022] The P1 socket 41 and the P2 socket 42 are arranged side by side, and the direction of the socket of the P1 socket 41 is opposite to that of the socket of the P2 socket 42. When the P plug-in is inserted into the P1 socket 41, the protrusion of the P plug-in blocks the socket of the P2 socket 42, preventing similar plug-ins in the control cabinet from being inserted into the P2 socket 42; when the P plug-in is inserted into the P2 socket 42, the protrusion of the P plug-in blocks the socket of the P1 socket 41, preventing similar plug-ins in the control cabinet from being inserted into the P1 socket 41, reducing the possibility of misassembly and facilitating assembly of the control cabinet.

[0023] The J1 socket 44, the J2 socket 45 and the J3 socket 46 are all connected to the outer edge of the circuit board 40, and the sockets of the J1 socket 44, the J2 socket 45 and the J3 socket 46 are all extended out of the outside of the circuit board 40, so as to facilitate the plugging and unplugging of the J1 plug-in 48, the J2 plug-in 49 and the J3 plug-in 50 on the corresponding sockets and facilitate the assembly of the control cabinet.

[0024] The P1 socket 41 is connected to the J1 socket 44 through the circuit on the back of the circuit board 40, the P2 socket 42 is connected to the J2 socket 45 through the circuit on the back of the circuit board 40, and the P3 socket 43 is connected to the J3 socket 46 through the circuit on the back of the circuit board 40. After the device is fixed inside the control cabinet, the possibility of workshop staff connecting the wrong wires can be greatly reduced by unplugging the J1 plug-in, J2 plug-in, and J3 plug-in, connecting the wires, and then plugging them in. When wiring the J1 plug-in, J2 plug-in, and J3 plug-in, other components can be avoided, and wiring is convenient. The P1 socket, P2 socket, and P3 socket can be connected to the control circuit of the control cabinet through the J1 plug-in, J2 plug-in, and J3 plug-in, which is convenient for assembly of the control cabinet.

[0025] All the above sockets and plug-ins are of the KF2EDGK series.
