Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of power converters, and particularly to an AC elastic piece and a circular conversion type power converter.
Background Art
[0002] A power converter is an auxiliary device used for charging small household appliances. The power converter can only be used in one direction, that is, the direction of the pins is fixed. Therefore, there is a problem that the user cannot charge with a power adapter due to insufficient space in the socket. In addition, the AC elastic piece and the conductive needle conduct electricity through single-point or single-surface contact, and there is a problem of poor contact stability.
Summary of the Invention
[0003] An object of the present invention is to provide an AC elastic piece and a circular conversion type power converter for improving the inconvenience in using a power converter in the prior art and the technical problem of poor contact stability between the AC elastic piece and the conductive needle.
[0004] To solve the above problems, the AC elastic piece of the present invention includes a first arc-shaped elastic piece, a second arc-shaped elastic piece, and four double-sided contact parts. The first arc-shaped elastic piece and the second arc-shaped elastic piece are arranged opposite to each other and are respectively recessed in a direction away from each other to form a circular region. A first mounting hole is provided at the central part of the first arc-shaped elastic piece, and a second mounting hole is provided at the end of the second arc-shaped elastic piece. The first mounting hole and the second mounting hole are parallel and are for inserting and fitting pins. The four double-sided contact parts are attached to the first arc-shaped elastic piece and the second arc-shaped elastic piece at equal angles and intervals in the circumferential direction of the circular region. Each double-sided contact part has a groove extending along the circumferential direction of the circular region, and each groove is for selectively inserting and fitting a conductive needle.
[0005] The circular conversion type power converter of the present invention includes an adapter component, a main body component, and the AC elastic piece. The adapter component includes two pins. The first arc-shaped elastic piece and the second arc-shaped elastic piece of the AC elastic piece are installed in the adapter component, and the two pins are respectively connected to the first mounting hole and the second mounting hole.
[0006] The adapter component is connected to the main body component, and two conductive pins of the main body component are inserted into two opposite double-sided contact parts of the AC elastic piece respectively. The technical effects of the present invention are shown as follows.
[0007] The AC elastic piece of the present invention is installed in a circular conversion type power converter and includes a first arc-shaped elastic piece, a second arc-shaped elastic piece, and double-sided contact parts. The first arc-shaped elastic piece and the second arc-shaped elastic piece are arranged opposite to each other and respectively recessed in a direction away from each other to form a circular area. A first mounting hole is provided at the central part of the first arc-shaped elastic piece, and a second mounting hole is provided at the end of the second arc-shaped elastic piece. The first mounting hole and the second mounting hole are parallel and are for inserting pins. Four double-sided contact parts are provided. The four double-sided contact parts are mounted on the first arc-shaped elastic piece and the second arc-shaped elastic piece at equal angles and intervals in the circumferential direction of the circular area. Each double-sided contact part has a groove extending along the circumferential direction of the circular area, and each groove is for inserting a conductive pin.
[0008] When using the AC elastic piece, by aligning the first mounting hole and the second mounting hole with two pins and aligning two of the four double-sided contact parts with two conductive needles, the power converter can be used normally. Since the four double-sided contact parts are arranged at equal angles circumferentially in the circular area, by aligning the two conductive needles with different double-sided contact parts, the direction of the power converter can be adjusted and used at 90 degrees, 180 degrees, 270 degrees, or 360 degrees. This can solve the problem that the user cannot charge with the power converter due to insufficient space in the socket. In addition, the double-sided contact part has a groove, and both side surfaces of the groove are in contact with the conductive needle to realize double-sided contact between the AC elastic piece and the conductive needle. This improves the contact stability.

Embodiments for Carrying out the Invention
[0010] As shown in FIGS. 6 and 7, the AC elastic piece 10 of the preferred embodiment of the present invention is installed in a circular conversion type power converter and includes a first arc-shaped elastic piece 11, a second arc-shaped elastic piece 12, and four double-sided contact parts 13. The first arc-shaped elastic piece 11 and the second arc-shaped elastic piece 12 are arranged opposite to each other and are respectively recessed in a direction away from each other to form a circular region. A first mounting hole 112 is provided at the central part of the first arc-shaped elastic piece 11, and a second mounting hole 122 is provided at the end of the second arc-shaped elastic piece 12. The first mounting hole 112 and the second mounting hole 122 are parallel and are for inserting and fitting the pin 25. The four double-sided contact parts 13 are attached to the first arc-shaped elastic piece 11 and the second arc-shaped elastic piece 12 at equal angles in the circumferential direction of the circular region, and each double-sided contact part 13 has a groove 131 extending along the circumferential direction of the circular region. This groove 131 is for inserting and fitting the conductive needle 55.
[0011] Specifically, as shown in FIG. 6, both the first mounting hole 112 and the second mounting hole 122 are installed in a square shape, and their dimensions are the same. As shown in FIGS. 1 to 6, FIG. 1 is a schematic diagram of the conductive needle 55, FIG. 2 is a schematic diagram with the usage direction of the power converter being 90 degrees, FIG. 3 is a schematic diagram with the usage direction of the power converter being 180 degrees, FIG. 4 is a schematic diagram with the usage direction of the power converter being 270 degrees, and FIG. 5 is a schematic diagram with the usage direction of the power converter being 360 degrees. By connecting the different double-sided contact portions 13 of the AC elastic piece 10 to the conductive needle 55, the adjustment of the usage direction of the power converter becomes possible.
[0012] As shown in FIGS. 1, 6, and 7, when using the AC elastic piece 10, connect the first mounting hole 112 and the second mounting hole 122 to two pins 25, and connect two of the four double-sided contact portions 13 to two conductive needles 55, then the power converter can be used normally. Since the four double-sided contact portions 13 are arranged at equal angles and spaced apart in the circumferential direction of the circular region, by connecting the two conductive needles 55 to different double-sided contact portions 13, the direction of the power converter can be adjusted to 90 degrees, 180 degrees, 270 degrees, or 360 degrees for use. This solves the problem that the user cannot charge with the power converter due to insufficient socket space. Also, the double-sided contact portion 13 has a groove 131, and both side surfaces of the groove 131 are in contact with the conductive needle 55 to achieve double-sided contact between the AC elastic piece 10 and the conductive needle 55. Thereby, abnormal problems such as arc discharge due to single-sided or single-point contact do not occur, the contact stability is improved, and the service life of the AC elastic piece 10 is also extended.
[0013] In a preferred embodiment of the present invention, each double-sided contact portion 13 includes a groove 131 formed by two opposing contact walls 132. One end of each contact wall 132 is connected to the first arc-shaped elastic piece 11 or the second arc-shaped elastic piece 12, and a protruding portion 133 protruding toward the groove 131 is provided at the other end.
[0014] As shown in Fig. 6, the double-sided contact portion 13 is integrally formed with the first arc-shaped elastic piece 11 or the second arc-shaped elastic piece 12. By bending the elastic piece, the first arc-shaped elastic piece 11 and the second arc-shaped elastic piece 12 with the double-sided contact portion 13 are formed. The two contact walls 132 are arranged opposite to each other to form a groove 131. During use, since the opposing surfaces of the two contact walls 132 are both in contact with the conductive needle 55, the contact area increases and the contact stability is improved. The contact wall 132 is provided with a protrusion 133, whereby the width of the upper part of the groove 131 is narrower than the width of the bottom of the groove 131, the two contact walls 132 sandwich the conductive needle 55, and the contact stability between the groove 131 and the conductive needle 55 is further improved.
[0015] The two opposing contact walls 132 form a groove 131 in the double-sided contact portion 13, and by providing a protrusion 133 on the contact wall 132, the contact stability between the groove 131 and the conductive needle 55 is improved.
[0016] Preferably, the cross-section of the protrusion 133 is installed in a V shape. The central part of the contact wall 132 is bent towards the direction of the groove 131 to form the protrusion 133. By installing the cross-section of the protrusion 133 in a V shape, the elasticity of the contact wall 132 is strengthened.
[0017] Preferably, each contact wall 132 is provided with a processing hole 134. The processing hole 134 penetrates in the thickness direction of the contact wall 132 and is installed in a square shape. The processing hole 134 reduces the cost and weight of the contact wall 132.
[0018] Since the circular conversion type power converter of the present invention includes the aforementioned AC elastic piece 10, it also has the advantageous effects of the aforementioned AC elastic piece 10, which will not be repeatedly described here.
[0019] As shown in FIGS. 1, 6 to 13, this circular conversion type power converter further includes an adapter component 20 and a main body component 50. The adapter component 20 includes two pins 25. The first arc-shaped elastic piece 11 and the second arc-shaped elastic piece 12 of the AC elastic piece 10 are both mounted within the adapter component 20, and these two pins 25 are respectively connected to the first mounting hole 112 and the second mounting hole 122. The adapter component 20 is connected to the main body component 50. Two conductive pins 55 on the main body component 50 are inserted into the two opposing double-sided contact portions 13 on the AC elastic piece 10.
[0020] The first mounting hole 112 and the second mounting hole 122 are respectively riveted to the two pins 25, and the two conductive pins 55 are respectively inserted into the grooves 131 of the two double-sided contact portions 13. As shown in FIGS. 1 to 5, FIG. 1 is a schematic diagram of the conductive pin 55, FIG. 2 is a schematic diagram of the power converter with a 90-degree usage direction, FIG. 3 is a schematic diagram of the power converter with a 180-degree usage direction, FIG. 4 is a schematic diagram of the power converter with a 270-degree usage direction, and FIG. 5 is a schematic diagram of the power converter with a 360-degree usage direction. By connecting different double-sided contact portions 13 of the AC elastic piece 10 to the conductive pins 55, the usage direction of the circular conversion type power converter can be adjusted.
[0021] Align the first mounting hole 112 and the second mounting hole 122 with the two pins 25, and align two of the four double-sided contact portions 13 with the two conductive pins 55, so that the circular conversion type power converter can be used normally. The four double-sided contact portions 13 are arranged at equal angles and spaced apart in the circumferential direction of the circular region. By aligning the two conductive pins 55 with different double-sided contact portions 13, the relative angle of the circular conversion type power converter can be adjusted. Thereby, usage at 90 degrees, 180 degrees, 270 degrees, and 360 degrees becomes possible, solving the problem that the user cannot charge with the power converter due to insufficient socket space. Also, there are grooves 131 in the double-sided contact portions 13, and both side walls of the grooves 131 contact the conductive pins 55, so that the AC elastic piece 10 and the conductive pins 55 are in double-sided contact, improving the stability of the contact.

As shown in FIGS. 7 and 10, the four avoidance holes 41 respectively correspond to the four double-sided contact parts 13, so that the insulating cover 40 does not affect the connection between the double-sided contact part 13 and the conductive needle 55.
