Description

Technical Field

[0001] This utility model relates to a power connector with a current suppressor. Background Technology

[0002] Power connectors are crucial links between power sources and devices, providing electrical energy for normal operation. They are essential components of electronic products and equipment, primarily functioning to connect two active devices and transmit current or signals. There are generally two connection methods for power connectors: 1. Connect the downstream load first, then the upstream power supply; 2. Connect the upstream power supply first, then the downstream load. When the downstream load has many adapters connected, the second connection method can generate a momentary inrush current, which can affect the circuit. Utility Model Content

[0003] This invention provides a power connector with a current suppressor.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A power connector with a current suppressor includes a housing, which comprises a bottom shell and a top cover. The bottom shell includes a base plate and left, right, front, and rear side plates disposed on the base plate. Through holes are provided on the front and rear side plates of the bottom shell for connecting circuits, with one end being an input port and the other an output port. The top cover has recesses opposite to the through holes. A mounting plate is disposed on the base plate of the bottom shell. A magnetic ring component, a resistor, a detection chip, a relay, and an electrolytic capacitor are disposed on the mounting plate. The magnetic ring component, relay, and electrolytic capacitor are disposed at the upper end of the mounting plate, and the resistor is disposed at the upper end of the magnetic ring component, relay, and electrolytic capacitor. The magnetic ring component, resistor, detection chip, relay, and electrolytic capacitor are all connected to a circuit.

[0006] Preferably, the outer shell is made of metal and has a square shape.

[0007] Preferably, the left and right sides of the plate are provided with opposite extension plates at both ends, and the front and rear side plates are fixed to the extension plates with screws.

[0008] Preferably, the bottom ends of both the front and rear side plates are provided with outwardly extending fixing plates, which are perpendicular to the front and rear side plates and are provided with fixing holes for fixing the power connector to a certain line.

[0009] Compared with the prior art, the power connector with current suppressor of this utility model detects whether there is a load connected at the back end by setting a detection chip inside the power connector. When the power is turned on but there is no load connected at the back end, the power connector does not work. When the load is connected, the resistor acts as a current shunt to prevent instantaneous surge current from being generated when many adapters are connected to the load, thereby affecting the circuit. The setting of the detection chip makes the current suppression effect the same when the front end is powered and the back end is powered. Attached Figure Description

[0010] Figure 1 This is a three-dimensional schematic diagram of the power connector with current suppressor according to this utility model.

[0011] Figure 2 This is a first exploded view of the power connector with current suppressor of this utility model.

[0012] Figure 3 This is a second exploded view of the power connector with current suppressor of this utility model. Detailed Implementation

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figures 1 to 3 As shown, the power connector with current suppressor includes a housing 1, which is made of metal and has a square shape. The housing 1 includes a bottom shell 11 and a top cover 12. The bottom shell 11 includes a bottom plate and a left side plate and a right side plate disposed on the bottom plate. The two ends of the left side plate and the right side plate are respectively provided with opposing extension plates. The front side plate and the rear side plate are fixed on the extension plates with screws. The front and rear side plates of the bottom shell 11 are provided with through holes 111. The bottom ends of the front and rear side plates are provided with outwardly extending fixing plates. The fixing plates are perpendicular to the front and rear side plates and are provided with fixing holes for fixing the power connector to a certain line. The through holes 111 are used to connect the line, one end of which is an input port and the other end is an output port. The top cover 12 is provided with a recess 121 opposite to the through holes 111.

[0015] A mounting plate 2 is provided on the bottom plate of the base shell 11. A magnetic ring component 3, a resistor 4, a detection chip (not shown in the figure), a relay 5, and an electrolytic capacitor 6 are mounted on the mounting plate 2. The magnetic ring component 3, relay 5, and electrolytic capacitor 6 are located at the upper end of the mounting plate 2, and the resistor 4 is located above the magnetic ring component 3, relay 5, and electrolytic capacitor 6. The magnetic ring component 3, resistor 4, detection chip, relay 5, and electrolytic capacitor 6 are all connected to the circuit. The magnetic ring component 3 is used to detect the current, the detection chip is used to detect whether a load is connected to the power output terminal, the resistor 4 acts as a current shunt, the relay 5 acts as a delay switch, and the electrolytic capacitor 6 acts as a filter.

[0016] When the detection chip detects that a load is connected to the output terminal and the input terminal is then energized, resistor 4 acts as a current shunt. When the detection chip does not detect a load connected to the output terminal and the input terminal is energized, the power connector does not function. When the load is reconnected, the detection chip detects that a load is connected to the back end, and resistor 4 can act as a current shunt to prevent instantaneous surge current from occurring when many adapters are connected to the load, which could cause the load's leakage current protector and circuit breaker to disconnect and affect the circuit. The setting of the detection chip ensures that the current suppression effect is the same whether the front end is energized or the back end is energized.

[0017] This utility model of a power connector with a current suppressor uses a detection chip inside the power connector to detect whether there is a load connected at the back end. When the power is on but there is no load connected at the back end, the power connector does not function. When the load is connected, resistor 4 acts as a current shunt to prevent instantaneous surge current from being generated when many adapters are connected to the load, thus preventing it from affecting the circuit. The setting of the detection chip ensures that the current suppression effect is the same whether the front end is powered or the back end is powered.

[0018] Finally, it should be noted that the above embodiments only illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
