Connectors, also known as connectors, generally refer to electrical connectors, i.e., devices that connect two active devices, carrying current or signals. A connector is a component that is frequently touched by the engineer of electronic engineering, and its function is very simple: a bridge for communication is erected between the blocked part or isolated and non-communicated circuits in the circuit, so that current flows, and the circuit achieves the preset function. Connectors are indispensable components in electronic devices. The connector forms and structures are widely varied, and there are various types of connectors depending on the application, frequency, power, application environment, and the like. For example, connectors for court lights and hard drives, and connectors for rocket lights are quite different. However, in any connector, it is necessary to ensure smooth, continuous and reliable flow of current. Due to the high quality and reliability of the connector, the connector is also widely applied to military systems such as aviation, aerospace, national defense and the like.

Through the technical scheme, the misplug prevention groove is formed in the plug-in part, so that when the plugs are plugged into each other, the misplug prevention groove and the misplug prevention groove of the other plug are matched and assembled with each other, and the condition that the butting direction is wrong under the condition of insufficient light can be avoided.

Preferably, the misplug prevention groove is positioned on the lower side of the plug interface.

Through above-mentioned technical scheme, prevent that mistake from inserting the recess and be located the interface downside, make space utilization reasonable.

Preferably, the misplug-preventing groove notch faces the plug interface.

Through the technical scheme, the notch of the misplug-preventing groove faces the plug interface, so that the misplug-preventing groove is not easy to enter dust.

Preferably, the insulating body is made of ABS, PC, PBT or PVC.

By the technical scheme, the ABS, PC or PBT materials have good insulating property and high temperature resistance, and can prevent the connector from electric leakage and damage; the PVC material has good chemical stability and can prevent the plug from aging.

Preferably, the positive electrode terminal and the negative electrode terminal are made of silver-copper alloy.

Through above-mentioned technical scheme, copper has good electric conductivity, and silver has good wearability to make anodal terminal and negative terminal electric conductivity better more durable simultaneously.

To sum up, the utility model discloses beneficial effect who has: the plug-in part is provided with the misplug prevention groove, so that when the plugs are plugged into each other, the misplug prevention groove and the misplug prevention groove of the other plug are matched and assembled with each other, and the situation of wrong plugging can not be generated.
