Description

Multi-section plug rotation positioning structure of power socket

technical field

The utility model relates to a plug positioning structure of a power socket, in particular to a design capable of multi-stage positioning when the plug rotates.

Background technique

With the rapid development of the electronic industry and the increasing update of science and technology, electronic products are developing in the direction of small size, easy to carry, and convenient to use, which has become a design trend of related industries.

However, devices with plugs in traditional electronic products, such as power sockets such as transformers, are originally designed so that the plug and the housing are fixed at a predetermined position and cannot be rotated to change the direction of insertion, and at the same time increase the overall volume of the product, thus It is unfavorable for users to carry and store. However, with consideration of size reduction and convenience of use, the design focus of the power socket is that the plug has a rotatable function.

Please refer to China Taiwan Patent Announcement No. 568433, which discloses a traditional plug rotatable power socket, which mainly includes a housing. The housing is provided with a nest on the end edge of the closed surface, and a plug structure is installed in the nest. The plug structure utilizes its plug-in terminal to be fixedly arranged in the rotating body, so that it can be linked with the rotating body and rotate to change the insertion direction, or make the volume smaller and easy to store. Edge, and welded wires, so that the plug structure can not only rotate but also form an electrical connection with the wires and the circuit board. In the above-mentioned published patents, a rotating structure of a plug is additionally disclosed, and a plug structure is also provided in the nest in the housing, and the plug structure is composed of two plug terminals, two guide pieces, a cross bar, The support block and the spring are composed of the two plug-in terminals and the two lead pieces are riveted together, and embedded on both sides of the cross bar, and the cross bar is positioned in the nest by the support block, and one end of the spring is installed In the receiving hole of the housing, the other end is arranged in the blind hole of the support block to realize the rotation of the plug and the sense of urgency during rotation.

Therefore, although the traditional technology disclosed above can achieve the function of making the plug rotate relative to the power socket, compared with the fixed plug structure design, the plug can rotate relative to the housing, and has the advantages of reducing product volume and being easy to carry; As far as the user is concerned, although the rotating power socket allows the user to adjust the insertion angle according to different insertion spaces, the plug does not have a multi-stage positioning effect when rotating, and cannot be used under various insertion angles. The plug and the power socket are positioned relative to each other, so when the plug is plugged in, the power socket is easy to swing arbitrarily under force, and even cause loosening, so there is still room for improvement.

Utility model content

The main purpose of this utility model is to provide a plug rotation positioning structure of the power socket, in addition to the plug can be rotated relative to the housing to reduce the product volume, easy to carry, but also through the gear set on the plug pivot and limit The pieces are mutually locked, so that the plug has a multi-stage positioning effect during the rotation stroke, and provides a hand feeling during rotation and positioning.

In order to achieve the above purpose of the utility model, in the preferred embodiment disclosed in the utility model, the power socket has a housing, and a plug with a pivot pivotally connected to the housing and relatively has a rotation stroke. The pivot is interlocked and has a plurality of toothed gear parts, and has a limiting piece, which is located inside the housing. The limiting piece extends out of the clamping part corresponding to the teeth, and during the rotation stroke of the plug, the The locking part can be coupled with the tooth part to form a position-limiting relationship.

Detailed ways

Relevant detailed description and technical content of the present utility model, now with regard to coordinating accompanying drawing, explain as follows:

Please refer to Fig. 1, which is a structural diagram of a preferred embodiment of the utility model, as shown in the figure: the utility model relates to a multi-section plug rotation positioning structure of a power socket, which has a housing 10, terminals 22 And the circuit board 60, which can be used as any type of power socket including a transformer, the housing 10 is composed of a base 11 and a top cover 12 coupled to the base 11 (see Figure 2-1), the The casing 10 is pivotally connected with a plug 20, the plug 20 is equipped with a pivot 21 for pivotally connecting the casing 10, and has a rotation stroke relative to the casing 10, and a plug 21 is provided on the pivot 21 to receive the pivot. The shaft 21 is interlocked and has a gear 30 with a plurality of teeth 31, wherein the plug 20 has the pivot 21 on both sides, and one of the pivots 21 has the gear 30 (it can also be the two pivots 21 All have the gear member 30), and have a limiting piece 40, which is positioned inside the housing 10 through the positioning groove 13. The limiting piece 40 extends out of the clamping portion 41 corresponding to the tooth portion 31, and the limiting piece 40 has a The flexible arm 42, and the clamping portion 41 is located at the end of the flexible arm 42 and has flexibility. In addition, a flexible elastic piece 50 is provided inside the housing 10, and a spring for positioning the elastic piece 50 is provided. The stop block 14, and the elastic piece 50 is normally against the end of the pivot 21, providing a sense of urgency when the plug 20 rotates.

Please refer to Figures 2-1 to 2-3, which are continuous action diagrams of the preferred embodiment of the present invention, as shown in the figure: the housing 10 is pivotally connected to the plug 20, so that the plug 20 can rotate relative to the housing 10 , when not in use, the plug 20 can be screwed into the bottom of the housing 10 (as shown in Figure 2-1), which has the advantages of reducing the volume and being easy to carry and store. The plug 20 is rotated outward (as shown in Figure 2-2, 2-3), so that the user can adjust the plugging angle when responding to different plugging environments, and during the rotation stroke of the plug 20, the The clamping portion 41 on the limiting piece 40 can be coupled with the tooth portion 31 of the gear member 30 to form a position-limiting relationship and produce a positioning effect; in addition, when the applied force overcomes the engaging force of the clamping portion 41, the tooth portion 31 The clamping part 41 is pushed against during the rotation stroke, thereby releasing the limiting relationship, whereby the plug 20 has a multi-stage positioning effect when rotating, and the plug 20 and the power socket can be positioned with each other at various insertion angles Therefore, when the plug 20 is plugged in, the power socket is not easy to swing arbitrarily and cause loosening under force.
