Description

Easy-to-plug universal socket

technical field

The utility model belongs to the field of household electrical appliances, in particular to an easy-to-plug universal socket with electrodes for a power socket.

Background technique

The principle of the power socket is to use the socket shrapnel to clamp the plug to complete the power transfer. Basically, 90% of the existing sockets use universal jacks that can be shared by various standard plugs at home and abroad. The general structure As shown in Figure 1 and Figure 2, there is an inclined section 11' in the vertical direction of the left and right shrapnel 1' and 2', and the angle with the vertical direction is C. Finally, due to the existence of the inclined section 11', the elastic force generated by it forms a grip on the plug; the rear elastic piece 3' is not provided with an inclined section in the vertical direction. Due to the different forms of standard plugs in various countries, when the plug is inserted into the socket, the socket shrapnel needs to open different gaps. After the insertion is completed, the plug is clamped by the rebound force. The existing socket structure often has plugs and sockets. If the meshing force is too tight or too loose, it will affect the smooth insertion and extraction of the plug, which is inconvenient to use, and will accelerate the wear of the socket and affect its service life; on the other hand, it will cause poor contact and affect the power transfer. use. The shrapnel structure is prone to fatigue. After frequent plugging and unplugging during use, the elastic force will weaken or disappear, resulting in poor contact and affecting power transfer.

Utility model content

In view of the above defects, the purpose of this utility model is to provide a structurally improved universal socket, which is easier to plug in and out and can ensure good clamping of the plug.

In order to achieve the above object, the utility model is realized through the following technical solutions:

An easy-to-plug universal socket, which is surrounded by a left elastic piece 1, a right elastic piece 2 and a rear elastic piece 3 folded from the bottom. The left elastic piece 1 and the right elastic piece 2 are left and right symmetrical. The left elastic piece 1 and the The right elastic piece 2 has an inclined section 11 and an inclined section 12 in the vertical direction; the rear elastic piece has an inclined section 31 in the vertical direction.

The plug sleeve described in the utility model has an inclined section 11 and an inclined section 12 on the left and right shrapnel in the vertical direction. Compared with the original structure, an inclined section 12 has been added, and a corresponding angle C has appeared on the basis of the original angle C. An angle B, when the plug is inserted into the socket, with the same gap A value, the change of the angle of one inclined section becomes the change of two inclined sections, which can deform the original inclined section 11. The angle is reduced, and it is not easy to cause plastic deformation beyond the scope of its elastic deformation. When the plug is pulled out, it can be well restored to its original shape, prolonging the effective service life of the socket; at the same time, after the plug is inserted, the inclined section and the vertical direction The included angle B becomes smaller, and more parts of the left and right shrapnel will fit with the plug, correspondingly increasing the contact area, ensuring the reliability of power transfer and reducing potential safety hazards.

Similarly, an inclined section 31 is also provided on the rear elastic piece, and an angle P is added in the vertical direction to have the same effect.

For the convenience of being connected with the power lead wire, the utility model has a connecting piece 4 punched and folded downwards at its bottom.

Further, in order to better contact the rear elastic piece with the plug electrode, there is a stamped and folded contact elastic piece 5 on the rear elastic piece 3 .

Compared with the existing plug-in sleeve, when the utility model satisfies opening the same gap, each section of the shrapnel has a smaller deflection deformation. On the one hand, it is not easy to cause plastic deformation, which increases the reliability and service life; in addition, it increases the The contact area can further reduce the preset elastic force while ensuring reliable contact, making it easier to plug in and out between the plug and the socket, and convenient for daily use.
