Description

Plug detachable multi-directional power supply

technical field

The present invention relates to a power supply, in particular to a multi-directional power supply with detachable plugs.

Background technique

When using electronic products, it is often necessary to use a power supply for power supply or charging. However, the plugs of the power supply are often limited by factors such as different specifications or different shapes of power plugs. Generally, users usually need to carry extra plugs The adapter is used to solve the above situation, so it causes inconvenience in use. In order to increase the applicability of the power supply, related companies have developed a power supply with a replaceable plug. This design combines the plug with the main body of the power supply in a replaceable manner, and then combines different types of plugs with the power supply according to the needs of use. on the supplier body.

In addition, the general wall-mounted power supply is a fixed plug. The power supply is fixed on the wall socket and the plugging direction cannot be changed. If the plugging direction is different from the distribution of the wires, or the location of the electrical appliance often needs to be changed , often causes twisting at the joint end of the cable and the plug, which affects the normal insertion of the power cord and easily blocks the placement of surrounding objects; therefore, another power supply that can change the direction of plug insertion has emerged as the times require . However, the plug of this kind of power supply that can change the direction of the plug is usually fixed on the socket in the direction of sliding connection. The plug is slid on the socket from another angle to change the insertion direction of the plug.

Although the above-mentioned detachable plug can achieve the purpose of changing the insertion direction, however, this type of plug still has a single use direction after assembly, and the way to change the insertion direction is still not very convenient, causing troubles in use.

Contents of the invention

An object of the present invention is to provide a plug detachable multi-directional power supply, so as to achieve a power supply that can easily change the plug type and its insertion direction.

Another object of the present invention is to provide a multi-directional power supply with detachable plugs, so that the plugs can be assembled in multiple directions behind the main body.

Yet another object of the present invention is to provide a multi-directional power supply with detachable plugs. In the power supply, the conductive terminals are definitely positioned in the plug to ensure good electrical conduction between the main body and the plug. .

In order to achieve the above object, the present invention provides a multi-directional power supply with a detachable plug, which includes a body with a plug-in space and two conductive terminals protruding in the plug-in space. The plug is combined with the body, and the plug includes The seat body has accommodating space, and the two guide pieces are relatively arranged in the accommodating space, the positioning cover is combined with the body and covers the accommodating space, the positioning cover is provided with two guide grooves corresponding to the two conducting terminals, and the brake ring It is arranged between the two guide pieces and the positioning cover. The inner edge of the brake ring corresponds to the two guide grooves and has multiple positioning grooves. Sliding in the middle and positioning in the positioning groove, and correspondingly connecting the two leading tabs.

Another object of the present invention is to provide a multi-directional power supply with detachable plugs, which simplifies the structure and volume of the plugs, and reduces the number of parts of the plugs, so as to achieve the purpose of easy assembly and disassembly.

Another object of the present invention is to provide a multi-directional power supply with detachable plugs. The power supply uses metal conductive terminals to contact the positioning grooves of the plastic brake pads to reduce friction between the two. Loss occurs, thereby increasing the service life of the plug and the multi-directional power supply.

Compared with the prior art, the present invention does not have a depressing structure for removing the plug. The plug of the present invention forms an included angle with the main body when assembled, and is positioned through rotation, so it is easy to replace and disassemble. In addition, when you want to change the insertion direction of the plug, the plug can be directly rotated in the opposite direction on the body, without first removing the plug, and then sliding it on the seat body from another angle to change the insertion of the plug direction; moreover, compared with traditional power supplies that use plastic parts that are prone to wear and tear as positioning, the present invention uses the positioning of the lead terminals (metal) between the positioning groove and the wall (plastic) of the guide groove to achieve the plug's Precise positioning, so that there is a good connection between the body and the plug, and has a more reliable positioning effect and service life, which further increases the practicability of the present invention.
