Description

Technical Field

[0001] The utility model relates to the field of electronic circuits, in particular to a definable connector pin circuit used for customized elevator buttons. Background Art

[0002] With the development of society and the improvement of living standards, elevators have become a common part of our lives. Due to the large market demand, many elevator brands have emerged. In pursuit of individuality, each elevator manufacturer uses different types of standard buttons, which results in different connectors and pin positions for standard buttons. In order to match the decoration style in later use, users need to modify and upgrade the elevator, and customized buttons can effectively improve the grade of the elevator and make the elevator perfectly integrated into the overall decoration style. But customized

[0003] In order to match the original standard buttons of the elevator, the electronic circuit needs to be redesigned according to the connectors and pins of the standard buttons. Due to the large number of elevator brands, the huge workload for designers will also cause a large amount of inventory backlog.

[0004] At present, there are only two ways to design electronic circuits for custom buttons in the industry: one is to design electronic circuits according to the connectors and pins of standard buttons; the other is to make fixed connectors and pins, and then separately provide button adapters. The first method brings a huge workload to designers and will also cause a large amount of inventory backlog; the second method increases the workload of manufacturers, especially the smaller the spacing between connectors, the more difficult it is to process the adapters.

[0005] In order to solve the above problems, the utility model provides an electronic circuit for flexibly welding plug-ins and defining connector pins on elevator customized buttons, which has the advantages of strong practicality, high matching degree, reduced workload, optimized inventory, and thus achieving the advantages of reducing costs. Utility Model Content

[0006] The purpose of the utility model is to provide a definable connector pin circuit for elevator customized buttons to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a definable connector pin circuit applied to a customized button of an elevator, comprising a connector circuit and a connector pin definition circuit, the connector circuit comprising connectors J1, J2, J5, J6, and J7, the connector pin definition circuit comprising at least 16 SC short contacts arranged in four groups, wherein the pins of the connectors J1, J2, J5, J6, and J7 are connected in parallel in the order of P1 to P4, and P1 to P4 are divided into four groups and respectively connected to one end of the 16 SC short contacts of the connector pin definition circuit, and the other ends of the 16 SC short contacts are divided into four groups and connected in parallel and then respectively connected to the four pins +, -, S1, and S2 of the original elevator circuit.

[0008] The original elevator circuit includes a power supply circuit, a two-color lighting circuit, a power supply circuit and a touch / mechanical switch control circuit, wherein the “+” path passes through a current-limiting resistor R1+Ra (where 12V is the elevator power supply 12V / 24V switching point, 24V when disconnected and 12V when closed) and is connected to the A group (A1, A2, A3, A4) lamps, the cathode of the A group lamps is connected to the emitter of the transistor Q3 and connected to the short-circuit point “A” to “-”; the “-” is connected to the base of the transistors Q2 and Q3 respectively after passing through resistors Re and Rf, and the other “+” path passes through a resistor Rd and is connected to the emitter of the transistor Q2, and the emitter of Q1 is connected to the cathode of the B group (B1, B2, B3, B4) lamps. "S1" and "S2" are respectively connected in parallel to the two dry contacts of the mechanical switch SW and the solid-state relay U3, and the closing of the solid-state relay is controlled by pin 6 of the touch chip U2. The 5V power supply of the touch chip is converted by the external power connector J3 / J4 through the DC-DC chip U1 (where PO is the connection point between the elevator power supply and the external power supply, and C4 is the isolation capacitor between the digital ground and the analog ground). When the human body touches TP, the touch chip pin 2 senses the charge change at the TP point, and outputs 5V from pin 6 to control the closing of U3 (where RL is the anti-interference resistor, C3 is the capacitor for adjusting the touch sensitivity, and T1 is the electrostatic protection diode).
