Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, in particular to a power adapter with a socket protection function. Background Art

[0002] An adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of a casing, a power transformer and a rectifier circuit. It can be divided into AC output type and DC output type according to its output type; it can be divided into wall-mounted type and desktop type according to the connection method.

[0003] Existing power adapters are usually provided with a plug end and a connection end, and the connection end is generally provided with a jack. However, because the jack structure is not protected, dust easily enters when not in use, resulting in poor sensitivity of the connection inside the jack and poor contact. Therefore, a protective structure is needed to protect the jack. In view of this, we propose a power adapter with a jack protection function. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a power adapter with a jack protection function to solve the technical problem that the jack end of the current power adapter has no protection structure, which makes it easy for dust to accumulate inside, resulting in reduced sensitivity of plugging and poor contact.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a power adapter with a jack protection function, including a power adapter box and a round hole plug, and a protective kit is installed on the outside of the round hole plug;

[0006] The protective kit includes a fixed ring, four arc-shaped plates are fixedly provided on the right side ring edge of the fixed ring, triangular baffles that fit together are fixedly provided on the other end faces of the four arc-shaped plates, a circular protrusion is fixedly provided on the side of the triangular baffle close to the round hole plug, and the circular protrusion fits together with the side close to the round hole plug, two limiting strips are fixedly provided on the outer wall of the round hole plug, and a clamping plate that fits with the upper and lower sides of the limiting strips is fixedly provided on the inner wall of the fixed ring.

[0007] Preferably, a spherical protrusion is fixedly provided on the upper side surface of the limiting strip, and a circular groove adapted to the spherical protrusion is opened on the board wall of the upper clamping plate.

[0008] Preferably, baffles are fixedly provided on the upper and lower side surfaces of the limiting strip, and the baffles are located at the front end of the limiting strip.

[0009] Preferably, an arc-shaped groove is provided at the connection between the fixing collar and the arc-shaped plate.

[0010] Preferably, the included angle between the side ends of the four triangular baffles is a right angle, the connecting edge between the two side edges of the right angle is an arc edge, and the arc angle of the arc edge is the same as that of the arc plate.

[0011] Preferably, a convex ring is fixedly provided on the outer wall of the fixing ring, and the convex ring is integrally connected to the fixing ring.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model can wrap and seal the round hole plug by combining the fixing ring, the arc plate and the triangular baffle, which can reduce the contact with the external environment and prevent dust from entering, thereby increasing the protection of the round hole plug. The four arc plates can be moved by the circular protrusions and deflected under the limit of the fixing ring, so as to open the gaps between the four triangles, which is convenient for the round hole plug to leak out without affecting the use. Through such structural coordination, the influence of dust on the round hole plug can be reduced and the sensitivity of the connection can be improved.

[0014] 2. In the utility model, the fixing ring can limit the connection position by combining the clamping plates on both sides with the limiting strips, and facilitate horizontal lateral movement. The position after movement can be limited by combining the spherical protrusion with the circular groove. The setting of the baffle can limit the installation position, so that the spacing between the four triangular baffles can be adjusted by position adjustment. The structure is simple and easy to use.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] Embodiment: A power adapter with jack protection function, see Figures 1 to 4 , comprising a power adapter box 1 and a round hole plug 2, a protective kit 3 is installed outside the round hole plug 2, which can wrap the round hole plug 2 to reduce dust contact;

[0023] The protective kit 3 includes a fixed collar 301, four arc plates 302 are fixedly provided on the right side of the fixed collar 301, and triangular baffles 303 that fit each other are fixedly provided on the other end surfaces of the four arc plates 302. A circular protrusion 304 is fixedly provided on the side of the triangular baffle 303 close to the round hole plug 2, and the circular protrusion 304 fits each other with the side close to the round hole plug 2. Two limiting strips 201 are fixedly provided on the outer wall of the round hole plug 2, and a fixed strip 201 that fits each other with the inner wall of the fixed collar 301 is fixedly provided. The clamping plate 306 is fitted on the upper and lower sides of the limiting strip 201; the position of the four arc-shaped plates 302 can be limited by the setting of the fixing ring 301, thereby forming a sleeve structure. The setting of the four-side arc-shaped plates 302 can reduce the resistance to folding and increase the folding angle, which can expand the spacing between the four triangular baffles 303. The effect of extrusion and deflection can be achieved by moving the circular protrusion 304. With the cooperation of the limiting strip 201 and the clamping plate 306, the fixing ring 301 can be easily moved horizontally.

[0024] Specifically, a spherical protrusion 202 is fixedly provided on the upper side surface of the limiting strip 201, and a circular groove 307 adapted to the spherical protrusion 202 is opened on the wall of the upper clamping plate 306; through the cooperation between the spherical protrusion 202 and the circular groove 307, the position of the fixed ring 301 can be limited when the two are combined, without affecting the use and operation of the round hole plug 2.

[0025] Furthermore, baffles 203 are fixedly provided on the upper and lower side surfaces of the limiting strip 201 , and the baffles 203 are located at the front end of the limiting strip 201 ; the installation position of the fixing ring 301 can be limited by the setting of the baffles 203 .

[0026] Furthermore, an arc-shaped groove 305 is provided at the connection between the fixing ring 301 and the arc-shaped plate 302; the provision of the arc-shaped groove 305 can increase the bending strength of the connection between the two and improve the bending angle.

[0027] It is worth noting that the angle between the side ends of the four triangular baffles 303 is a right angle, the connecting edge between the two side edges of the right angle is an arc edge, and the arc angle of the arc edge is the same as that of the arc plate 302; such a shape setting can ensure that the side edges of the four triangular baffles 303 are fitted and connected, thereby improving the sealing of the connection.

[0028] It is worth noting that a convex ring 308 is fixedly provided on the outer wall of the fixing ring 301, and the convex ring 308 is integrally connected with the fixing ring 301; the provision of the convex ring 308 can increase the fulcrum points, making it convenient to pull the protective kit 3 to move.

[0029] Working principle: first, the protective kit 3 is put on the outside of the round hole plug 2. The circular protrusion 304 contacts the side end of the round hole plug 2 to limit the installation position of the protective kit 3, which plays a supporting role. When the round hole plug 2 needs to be used, it can be pulled backward through the protrusion 308 on the outside of the fixing ring 301, so that the triangular baffle 303 is pressed and deflected outward under the movement of the circular protrusion 304, driving the arc plates 302 on the four sides to deflect, so that the internal round hole plug 2 can leak out. When the clamping plate 306 on the inner wall of the fixing ring 301 moves to the position of the spherical protrusion 202 on the limiting strip 201, the two are combined by squeezing, and then when the spherical protrusion 202 and the circular groove 305 are aligned, they can be stuck to each other, so as to limit the position of the protective kit 3, which does not affect the plugging and use of the round hole plug 2. Through such structural cooperation, the protection of the round hole plug 2 can be improved, the sensitivity of the connection affected by dust entry can be reduced, the problem of poor contact can be reduced, and it is convenient to use.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
