[0002] The in-vehicle discharging socket is a socket located inside the vehicle that provides 220V alternating current. It allows the vehicle owner and passengers to use small electrical devices such as laptops inside the vehicle, and can also provide charging services for these devices. The disadvantages of traditional in-vehicle discharging sockets are as follows: 1. After the vehicle is powered on, the discharging socket is charged, that is, it is often charged even when no electrical device is connected to the socket, posing a great safety hazard; 2. The panel is fixed and cannot be replaced arbitrarily; 3. There is no over-temperature protection. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an in-vehicle discharging socket with high safety performance, a replaceable panel and an internal microswitch with temperature detection.

[0004] To solve the above problems, the technical solutions adopted by the utility model include: a socket housing and an L-pole spring terminal, a PE-pole spring terminal and an N-pole spring terminal arranged inside the socket housing. An insulating bushing is arranged inside the upper end of the socket housing, and a socket panel is arranged outside the lower end. A first protection door and a second protection door are arranged inside the insulating bushing. A first return spring is arranged between the first protection door and the second protection door. It is characterized in that: a microswitch trigger plate moving in the opposite direction is arranged on one side of the second protection door. A microswitch is arranged at the middle position outside the microswitch trigger plate corresponding to the insulating bushing. Second return springs are arranged at both ends outside the microswitch trigger plate.

[0005] The in-vehicle discharging socket with an internal microswitch is characterized in that: a first inclined pressure surface is arranged on the second protection door, and a second inclined pressure surface opposite to the first inclined pressure surface is arranged on the microswitch trigger plate.

[0006] The in-vehicle discharging socket with an internal microswitch is characterized in that: the L-pole spring terminal and the N-pole spring terminal are installed with an LED circuit board through integrally formed pin leads. A light guide column for aligning the LED on the LED circuit board is arranged on the insulating bushing, and a light-emitting convex block protruding from the socket panel is arranged on the light guide column.

[0007] The in-vehicle discharging socket with an internal microswitch is characterized in that: a temperature sensor fitting the L-pole spring terminal or the N-pole spring terminal is arranged inside the socket housing.

[0008] The in-vehicle discharge socket with a built-in microswitch is characterized in that: C-shaped wiring frames embedded in the socket housing are provided at the bottoms of the L-pole spring terminals, the PE-pole spring terminals and the N-pole spring terminals, nuts are provided inside the C-shaped wiring frames, a wiring cavity is provided at the bottom of the socket housing, and a wiring nose connected to the nut by a screw is provided inside the wiring cavity.

[0009] A rear cover covering the wiring cavity is provided at the rear end of the socket housing, and the socket panel is connected to a hook on the side wall of the socket housing through a hanging hole plate on the side.

[0014] The advantages of the in-vehicle discharge socket with a built-in microswitch of the present utility model are as follows:

[0015] First, a microswitch is built in the discharge socket. When an electrical device (i.e., a plug) is inserted, the microswitch will trigger the microswitch towards the trigger plate and send a signal to the vehicle power management system, and then the vehicle powers on the socket, so that the socket is not powered on when no electrical device is connected, thus greatly improving safety.

[0016] Second, the discharge socket is modularized, and the customer can replace the panel without overall disassembly to adapt to different shapes.

[0017] Third, a temperature sensor is added, and when the socket is in an abnormal high-temperature situation, it can cut off the power by itself.
