Description

Technical Field

[0001] The utility model belongs to the technical field of traffic signal controllers and traffic control equipment, in particular to the technical field of plate connection, in particular to a current and signal integrated connector. Background Art

[0002] Traffic signals are special equipment used to control traffic signals on urban roads, railways, ports, etc. With the development of traffic signal control theory, it has now developed into the third generation of coordinated signal machines. Traffic signals are usually composed of hardware and software parts. The hardware part is usually installed in the cabinet at the traffic intersection, and consists of a backplane, power board, main control board, input and output board, communication board, etc. At present, the relevant national standards for traffic signals in China are GB 25280-2016 "Road Traffic Control Signal Machine" and GB / T 20999-2017 "Data Communication Protocol between Traffic Signal Controller and Host Computer". These two standards specify in detail the installation dimensions of the traffic signal cabinet, the functions of the traffic signal, the communication methods, and the technical requirements that need to be met. However, there are no detailed regulations on the internal dimensions and board dimensions of traffic lights, so the designs of various domestic manufacturers are different. However, due to historical and external cabinet size reasons, most manufacturers have adopted the standard 4U chassis size. Therefore, the width of the board inside the traffic signal must also be designed according to the 4U size, usually not exceeding 150mm. The actual maximum available height is 140mm. The width of the board corresponds to the length of the connector.

[0003] Since the functional boards and backplanes of traffic signals are generally interconnected through a European connector that complies with the IEC60603-2 (DIN41612) standard, a vertical board structure is formed. And because traffic signals need to process a large number of input signals and output control signals, the European connectors of the IEC60603-2 (DIN41612) standard with more contact pairs and the longest length are usually selected as universal connectors. The maximum length of this type of connector is 95mm. Normally, traffic signals are powered by AC220V mains electricity, and the power supply current is generally 5-10A. Considering the voltage resistance requirements, the power supply part and the signal processing and output part are generally separated. Therefore, a connector that can pass a larger current needs to be selected separately for power supply. Due to the limited width of the board, the length of the power connector is required to be smaller.

[0004] In recent years, various traffic signal users have required traffic signals to reduce their failure rates. Therefore, monitoring the stability and power of the signal power supply has become a trend. In addition, multiple power boards are also required to be interconnected, which requires adding power monitoring and connection channels to the original power supply circuit, making the number of connector contact pairs even tighter. The original design of separating the power connector and the signal connector is gradually unable to meet the usage requirements. Utility Model Content

[0030] Further preferably, in one embodiment, in combination Figure 3 and Figure 4 The plug comprises a first outer shell 10, three current contact pairs mounted on the first outer shell 10, namely a first current pin 11, a second current pin 12, and a third current pin 13, and four signal contact pairs mounted on the first outer shell 10, namely a first signal pin 14, a second signal pin 15, a third signal pin 16, and a fourth signal pin 17; the first current pin 11, the second current pin 12, and the third current pin 13 are collinearly arranged in the X direction, with a spacing of 5.08 mm between each pair; the first signal pin 14 The third signal pin 16 is arranged in a collinear manner in the X direction with a spacing of 2.54 mm; the second signal pin 15 and the fourth signal pin 17 are arranged in a collinear manner in the X direction with a spacing of 2.54 mm; the first signal pin 14 and the second signal pin 15 are arranged in a collinear manner in the Y direction with a spacing of 2.54 mm; the third signal pin 16 and the fourth signal pin 17 are arranged in a coplanar manner in the Y direction with a spacing of 2.54 mm, and the spacing between the third flow pin 13 and the first signal pin 14 and the second signal pin 15 in the X direction is 7.62 mm.

[0031] Further preferably, in one embodiment, in combination Figure 5The socket includes a second outer shell 20, a first current jack 21, a second current jack 22, a third current jack 23, a first signal jack 24, a second signal jack 25, a third signal jack 26 and a fourth signal jack 27 mounted on the second outer shell 20, and the arrangement positions correspond to the first current pin 11, the second current pin 12, the third current pin 13, the first signal pin 14, the second signal pin 15, the third signal pin 16 and the fourth signal pin 17. The detailed arrangement is as follows: the first current jack 21, the second current jack 22 and the third current jack 23 are arranged in the same line in the X direction, and the spacing between them is 5.08 mm. The first signal jack 24 and the third signal jack 26 are collinearly arranged in the X direction, with a spacing of 2.54 mm between them; the second signal jack 25 and the fourth signal jack 27 are collinearly arranged in the X direction, with a spacing of 2.54 mm between them; the first signal jack 24 and the second signal jack 25 are collinearly arranged in the Y direction, with a spacing of 2.54 mm between them; the third signal jack 26 and the fourth signal jack 27 are coplanarly arranged in the Y direction, with a spacing of 2.54 mm between them.

[0034] Contact pair Dielectric Withstand Voltage Between power contact pairs 1500Vr.ms Between signal contact pairs 1500Vr.ms Between power contact pairs and adjacent signal contact pairs 1500Vr.ms

[0035] Since the AC220V voltage of the mains supplied by the power contact pair is higher than the rated working voltage of the low-voltage electronic components in the traffic signal, in order to prevent the high-voltage arc generated at the moment of contact and separation of the contact pair from damaging the internal electronic components, the power contact pair is required to have a hot-swap function. Therefore, after the second current pin 12 located in the middle of the plug is assembled into the housing, the exposed length is 1mm longer than the first power pin 11 and the third power pin 13. Figure 6 As shown. The second current pin 12 and the second current socket 22 are usually used to connect the grounding line of the system. After the plug and socket are plugged in, compared with the other two pairs of contact pairs, the second current pin 12 and the second current socket 22 can be in contact first and conduct the grounding circuit, so that the high-voltage arc or other interference current generated inside the traffic signal can be released through the grounding circuit; when the plug and the socket are separated, the second current pin 12 and the second current socket 22 can be separated later, so that the high-voltage arc generated when the traffic signal is disconnected from the power supply or other interference currents remaining inside the traffic signal can be released through the grounding circuit, thereby realizing the hot plug function.
