Description

Technical Field

[0001] This utility model belongs to the field of electrical connection and testing technology, and specifically relates to a stacked electrical connector. Background Technology

[0002] With the diversification of electrical equipment and the increasing complexity of testing requirements, traditional electrical connectors have significant limitations in terms of functional adaptability: DC power-taking plugs have a fixed structure, only compatible with corresponding interfaces, making it difficult to adapt to different interface requirements with a "one device, one charger" approach; temporary electrical connections are cumbersome and time-consuming, and pose safety hazards such as poor contact; fixed probe-type instruments cannot flexibly adapt to special connectors or contact surfaces, limiting the expansion of testing scenarios. In existing technologies, using traditional single connectors for power supply is difficult to handle matching irregularly shaped contacts (such as arc-shaped electrodes, annular contact surfaces, and slit-type interfaces). Modular connectors generally suffer from limited combination methods, high structural redundancy, and inconvenient storage. Therefore, there is an urgent need for an electrical connector that can achieve multi-scenario adaptability, rapid assembly and disassembly, safe operation, and easy storage through stacking and plugging combinations, thereby overcoming the technical bottlenecks of traditional connectors in terms of scenario adaptability, operational convenience, and safety.

The terminal block is used to connect wires, and the first socket is matched with the banana plug. A plug-in connector, one end of which is a power-connecting clamp, including an alligator clamp, a duckbill clamp, or a tiger-mouth arc-shaped clamp, and the other end of which is provided with a second socket that matches the banana plug connector, the second socket being provided with a conductor that is electrically connected to the power-connecting clamp. A bidirectional insulated connector, wherein each end of the bidirectional insulated connector is provided with an insulated banana head; In the stowed state, one end of the bidirectional insulated connector is inserted into the first socket, and the other end is inserted into the stacked connector that is not in use.

[0005] Furthermore, in the above-mentioned stacked electrical connector structure, the terminals and wires are connected by threaded engagement or snap-fit.

[0006] Furthermore, the above-mentioned stacked electrical connector structure includes two straight connectors. The first straight connector is connected to one end of the positive wire through a terminal block, and the second straight connector is connected to one end of the negative wire through a terminal block. The other ends of the positive and negative wires are connected to a C14 standard socket.

[0007] Furthermore, the aforementioned stacked electrical connector structure also includes a DC-DC converter, which is connected to a C13 plug.

[0008] Furthermore, in the above-mentioned stacked electrical connector structure, the DC-DC converter includes a converter housing, which is equipped with a C13 plug, a DC-DC voltage regulation module, an overvoltage / overcurrent / overtemperature protection circuit, an LED display screen, a voltage and fault display unit, and a USB interface.

[0009] Furthermore, in the above-mentioned stacked electrical connector structure, the positive wire is connected to a reverse connection box, and the reverse connection box contains a diode or a bridge circuit (the bridge circuit requires the positive and negative wires to be connected together to set up a reverse connection box).

[0010] The beneficial effects of this utility model are as follows: By designing a specific structure for the straight-insertion connector and the stacked connector, and using a bidirectional insulated connector structure in conjunction, the straight-insertion connector can connect wires through the terminal block. Its banana head can be used as a connector by direct insertion or as a transfer device.

A bidirectional insulated connector 5, wherein each end of the bidirectional insulated connector 5 is provided with an insulated banana head 2; like Figure 1 As shown, in the retracted state, one end of the bidirectional insulated connector 5 is inserted into the first socket, and the other end is inserted into the deactivated stacked connector.

[0015] Please refer to Figures 1 to 3 Alligator chuck 1 has a serrated clamping structure at the front end; banana chuck 2 has a cylindrical expansion insert structure at the front end; duckbill chuck 3 has a flat clamping structure at the front end; tiger mouth arc chuck 4 has an openable arc clamping piece at the front end and a tiger mouth in the middle.

[0016] Preferably, the terminal block and the wire 6 are connected by a threaded connection or a snap-fit ​​method.

[0017] Reference Figures 4 to 7 Preferably, in the application scenario of DC power supply, it includes two direct plug connectors. The first direct plug connector is connected to one end of the positive wire 6 through a terminal block, and the second direct plug connector is connected to one end of the negative wire 6 through a terminal block. The other ends of the positive wire 6 and the negative wire 6 are connected to the C14 standard socket 8.

[0018] It also includes a DC-DC converter 9, which is connected to a C13 connector 10.

[0019] The DC-DC converter 9 includes a converter housing 13, which is equipped with a C13 plug 10, a DC-DC voltage regulation module 14, an overvoltage / overcurrent / overtemperature protection circuit 16, an LED display screen 11, a voltage and fault display unit 15, and a USB interface 12.

[0020] Preferably, the positive conductor 6 is connected to a reverse protection box 7, and the reverse protection box 7 has a built-in diode or bridge circuit (the bridge circuit requires the positive and negative conductors to be connected together to set up a reverse protection box).

[0021] In the above embodiments, the voltage regulation module realizes a wide input range of DC 12V-100V and a 5V output; the voltage and fault display unit 15 displays the input voltage and fault type in real time; the overvoltage / overcurrent / overtemperature protection circuit 16 can automatically switch circuits and display the fault type when there is overvoltage, overcurrent, or overtemperature.

[0022] like Figure 6 As shown, when drawing power from different types of DC interfaces, select the appropriate connector based on the interface shape to connect to the power source.
