[0002] When the commonly used three-pole detachable plug is installed with an external power cord, it is necessary to use two screws and a line card with two through holes to fix the external power cord on the plug shell. and less secure
[0003] And when the current is large, the wires are prone to heat. If the quality of the outer insulation sleeve is poor, it is easy to burn through the insulation sleeve. When the two wires touch each other, a short circuit will occur, resulting in electrical damage and even fire.

Embodiment Construction
[0039] The present invention will be further described below with reference to the accompanying drawings.
[0040] The present invention is a three-pole detachable plug, such as figure 1 As shown in , it includes a plug shell 1, which is different from the prior art in that: the plug shell 1 is provided with a clamping bracket 2, and the front opening of the plug shell 1 is provided with a bottom shell 3, and the bottom shell 3 is provided with There are three sets of bolt assemblies 4, the front end of the wire clamping bracket 2 is fixedly connected to the center of the inner surface of the bottom case 3, the surface of the wire clamping bracket 2 is deviated to one side and longitudinally opened with a thread embedding groove 5, and one end of the thread embedding groove 5 extends to the wire clamping bracket The front end of 2 is in the shape of an opening, and the other end of the thread embedding groove 5 extends to the rear end of the clamping bracket 2 and is in the sh...

The invention discloses a three-pin detachable plug. A wire-clamping support is disposed in a plug housing. The front end of the wire-clamping support is fixedly connected with the center of the inner surface of a bottom casing. A wire trough is lengthways disposed on the surface of the wire-clamping support in a way of getting closer to a side than the other side. One end of the wire trough extends to the front end of the wire-clamping support and is in an opening shape. The other end of the wire trough extends to the rear end of the wire-clamping support and is in a triangular opening shape. Wire-clamping teeth are uniformly distributed on a sidewall of the wire trough. An inclined surface is formed on a position, close to the triangular opening, on the other sidewall of the wire trough. A wire-clamping sliding block is disposed on the triangular opening on the other end of the wire trough. The three-pin detachable plug is ingenious in overall design. The triangular wire-clamping sliding block is used for fixing wires and achieves a stable fastening effect. Ribs distributed transversely and lengthways are used for naturally separating the wires so as to effectively prevent short circuit between the wires and prevent accidents, thereby further improving product security.
Description
technical field [0001] The invention relates to the technical field of electrical plugs, in particular to a three-pole detachable plug, and in particular to its mechanical connection structure. Background technique [0002] When the commonly used three-pole detachable plug is installed with an external power cord, it is necessary to use two screws and a line card with two through holes to fix the external power cord on the plug shell. and less secure. [0003] And when the current is large, the wires are prone to heat. If the quality of the outer insulation sleeve is poor, it is easy to burn through the insulation sleeve. When the two wires touch each other, a short circuit will occur, resulting in electrical damage and even fire. [0004] Therefore, it is still necessary to further improve the assembly structure of the existing three-pole detachable plug to effectively improve the stability and safety of the product. Contents of the invention [0005] The object of the ...
