Description

Technical Field

[0001] This utility model relates to a conversion socket, and more particularly to an output terminal of a conversion socket. Background Technology

[0002] A travel adapter is a portable socket with multiple plugs and sockets, suitable for use in different countries. It has output terminals on the upper side and input terminals on the lower side, connected by a fuse. In use, the plug is inserted into the socket, and the output terminals hold the plug's prongs, making contact and conducting electricity. However, plug prong sizes vary between countries. When a larger prong is inserted into the output terminal, it stretches the terminal further. Over time, the spring force of the output terminal's retaining arm will decrease. When a smaller prong is inserted, the output terminal will lack the clamping force to hold the smaller prong tightly, potentially resulting in ineffective contact and no electricity flow, affecting the stability of conductivity. Utility Model Content

[0003] The purpose of this invention is to provide an output terminal for a converter socket that can be used with plugs of different national standards, thereby improving the applicability and conductivity stability of the converter socket.

[0004] To achieve the above objectives, this utility model provides an output terminal for a conversion socket, comprising a conductive body, a pair of first elastic clamping arms, and a pair of second elastic clamping arms. The first elastic clamping arms are disposed on opposite sides of the conductive body, and a clearance hole communicating with the inner and outer sides is provided on the lower side of the first elastic clamping arms. The second elastic clamping arms are disposed on opposite sides of the conductive body and are located in the clearance holes one-to-one. The distance between the contact points of the two first elastic clamping arms is greater than the distance between the contact points of the two second elastic clamping arms. Compared with the prior art, by providing a pair of first elastic clamping arms and a pair of second elastic clamping arms on the conductive body, and positioning the second elastic clamping arms at the clearance holes of the first elastic clamping arms, the first and second elastic clamping arms can form two clamping positions at different heights. Furthermore, by making the distance between the contact points of the two first elastic clamping arms greater than the distance between the contact points of the two second elastic clamping arms, the first elastic clamping arms can clamp larger plugs, and the second elastic clamping arms can clamp smaller plugs. This prevents the elasticity of the second elastic clamping arms from decreasing after a large plug is inserted, thus ensuring that both large and small plugs can effectively contact the elastic clamping arms. Therefore, this invention is applicable to plugs of different national standards, effectively improving the applicability and conductive stability of the adapter socket.

[0005] Specifically, the conductive body, the pair of first elastic clamping arms, and the pair of second elastic clamping arms are all integrally formed.

[0006] Specifically, the first elastic clamping arm extends upward from the edge of the conductive body, and the two first elastic clamping arms are inclined toward each other; the second elastic clamping arm extends upward from the edge of the conductive body, and the two second elastic clamping arms are inclined toward each other.

[0007] Specifically, the height of the first elastic clamping arm is greater than the height of the second elastic clamping arm, and the width of the first elastic clamping arm is greater than the width of the second elastic clamping arm. This allows the first elastic clamping arm to be adapted to large plugs, improving clamping stability.

[0008] Specifically, the top end of the first elastic clamping arm and / or the second elastic clamping arm is provided with a guide portion that slopes upward and outward. The guide portion allows the insert to more easily mate with it, effectively improving assembly convenience. Attached Figure Description

[0016] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] Please see Figures 1 to 4The fuse connection terminal 100 of the adapter socket of this utility model includes an output terminal 1, an upper clamping terminal 2, a fuse 3, a lower clamping terminal 4, and an input terminal 5. The output terminal 1 is electrically connected to the upper clamping terminal 2. The input terminal 5 is electrically connected to the lower clamping terminal 4. The upper clamping terminal 2 has a pair of first clamping pieces 21, the inner side of which has an arc-shaped first contact surface 211. The two first clamping pieces 21 electrically clamp the upper end of the fuse 3. The fuse 3 has a cylindrical structure, and the first contact surface 211 is electrically connected to and in surface contact with the first conductive end 31 at the upper end of the fuse 3. The lower clamping terminal 4 is integrally formed with the input terminal 5. The lower clamping terminal 4 has a pair of second clamping pieces 41, the inner side of which has an arc-shaped second contact surface 411. The two second clamping pieces 41 electrically clamp the lower end of the fuse 3, and the second contact surface 411 is electrically connected to and in surface contact with the second conductive end 32 at the lower end of the fuse 3. Furthermore, the lower edge of the first clip 21 is provided with an outwardly inclined first guide portion 21a to facilitate the connection of the safety tube 3 with the first clip 21 from below. Similarly, the upper and lower edges of the second clip 41 are also provided with guide portions similar to those of the first clip 21.

[0018] Please see Figures 1 to 3 and Figure 5 The output terminal 1 is detachably connected to the upper clamping terminal 2. This not only reduces the manufacturing difficulty of the conductive terminal but also makes assembly faster. Preferably, the upper clamping terminal 2 includes a clamping body 22, a insert 23, and a first clamping piece 21, with the insert 23 and the first clamping piece 21 disposed on the clamping body 22; the clamping body 22, the insert 23, and the first clamping piece 21 are integrally formed. The insert 23 is located on the side of the clamping body 22 facing away from the first clamping piece 21, and the insert 23 extends upward. The output terminal 1 has a sleeve 14 with an opening 141 facing the insert 23. The insert 23 is inserted into the sleeve 14 through the opening 141, and the surface and bottom surface of the insert 23 are in conductive contact with the two inner walls of the sleeve 14, respectively. By providing a sleeve 14, the two inner walls of the sleeve 14 can make surface contact with the surface and bottom surface of the insert 43 for electrical conductivity, thereby further reducing the resistance at the contact point and preventing excessive heat generation due to increased current. Specifically, the opening 141 of the sleeve 14 has an outwardly extending second guide portion 142, which guides the insert 23 into the sleeve 14. Providing the second guide portion 142 makes it easier for the insert 23 to mate with the sleeve 14, effectively improving the convenience of assembly.

[0019] For example Figure 3As shown, the upper clamping terminal 2 is provided with a connecting hole 241. Specifically, the upper end of the clamping body 22 is bent to form a connecting part 24, and the connecting hole 241 is provided on the connecting part 24. In this way, the fuse 3 connecting terminal 100 can be fixed inside the adapter socket by connecting to the connecting hole 241 with a screw.

[0020] This invention features a pair of first clamping plates 21 on the upper clamping terminal 2, each with an arc-shaped first contact surface 211; and a pair of second clamping plates 41 on the lower clamping terminal 4, each with an arc-shaped second contact surface 411. By having the two first contact surfaces 211 make surface contact with the first conductive end 31 of the fuse 3, and the two second contact surfaces 411 make surface contact with the second conductive end 32 of the fuse 3, the electrical contact area between the fuse 3 and the upper and lower clamping terminals 2 and 4 is significantly increased. This reduces the resistance at the contact point and prevents excessive heat generation due to increased current. Furthermore, the first and second contact surfaces 211 and 411 accelerate the dissipation of heat from the fuse 3, preventing abnormal temperature rise of the fuse 3 under normal use and effectively ensuring its safety performance.

[0021] Please see Figures 5 to 7 The output terminal 1 includes a conductive body 11, a pair of first elastic clamping arms 12, a pair of second elastic clamping arms 13, and a socket 14. The first elastic clamping arms 12 and the second elastic clamping arms 13 extend upward from the edge of the conductive body 11 relative to the conductive body 11, and the socket 14 extends downward relative to the conductive body 11. The two first elastic clamping arms 12 are respectively disposed on opposite sides of the conductive body 11, and the lower side of the first elastic clamping arms 12 has a clearance hole 121 communicating with the inner and outer sides. The two second elastic clamping arms 13 are respectively disposed on opposite sides of the conductive body 11 and are located one-to-one in the clearance hole 121. The distance between the contact points of the two first elastic clamping arms 12 is greater than the distance between the contact points of the two second elastic clamping arms 13.

[0022] Please see again Figures 5 to 7The conductive body 11, a pair of first elastic clamping arms 12, a pair of second elastic clamping arms 13, and the socket 14 are integrally formed. Specifically, the first elastic clamping arms 12 extend upward from the edge of the conductive body 11, and the two first elastic clamping arms 12 are inclined towards each other. The height of the first elastic clamping arms 12 is greater than the height of the second elastic clamping arms 13, and the width of the first elastic clamping arms 12 is greater than the width of the second elastic clamping arms 13. This allows the first elastic clamping arms 12 to be adapted to large plugs, improving clamping stability. The second elastic clamping arms 13 extend upward from the edge of the conductive body 11, and the two second elastic clamping arms 13 are inclined towards each other. The top ends of the first elastic clamping arms 12 and the second elastic clamping arms 13 are respectively provided with guide portions 12a and 13a that are inclined upward and outward. The guide portions 12a / 13a make it easier for the plug 23 to cooperate with the guide portions 12a / 13a, effectively improving the convenience of assembly.

[0023] Compared with the prior art, by providing a pair of first elastic clamping arms 12 and a pair of second elastic clamping arms 13 on the conductive body 11, and positioning the second elastic clamping arms 13 at the clearance holes 121 of the first elastic clamping arms 12, the first elastic clamping arms 12 and the second elastic clamping arms 13 can form two clamping positions at different heights. Furthermore, by making the distance between the contact points of the two first elastic clamping arms 12 greater than the distance between the contact points of the two second elastic clamping arms 13, the first elastic clamping arms 12 can clamp larger plugs, and the second elastic clamping arms 13 can clamp smaller plugs. This prevents the elastic force of the second elastic clamping arms 13 from decreasing after a large plug is inserted, thus ensuring that both large and small plugs can effectively contact the elastic clamping arms. As a result, it can be used with plugs of different national standards, improving the applicability and conductivity stability of the adapter.

[0024] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model shall still fall within the scope of the present utility model.
