Technical Field

[0001] The utility model relates to a conductive connection device, in particular to an adapter plug. Background Art

[0002] An adapter plug can convert one type of plug into another type. According to different usage requirements, different connection pins are configured on the adapter plug. Usually, different structures need to be designed inside the adapter plug to fix the connection pins. When manufacturing and assembling the adapter plug, multiple connection pins are individually installed and positioned in different structures, resulting in a complex internal structure of the adapter plug and low production efficiency. Therefore, there is an urgent need for an adapter plug that is convenient for production. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an adapter plug to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve its technical problems is as follows:

[0005] An adapter plug includes: a bottom cover; connection pins integrally connected to the bottom side of the bottom cover, a connection head is formed at the top end of the connection pin, the connection head extends upward out of the bottom cover, and the number of the connection pins is multiple; a circuit board connected to the top side of the bottom cover, the connection head is electrically connected to the circuit board; a box body, multiple jacks are arranged on the top side of the box body, a cavity with an opening facing downward is formed by surrounding inside the box body, and the bottom cover is connected to the bottom of the box body and covers the cavity.

[0006] This technical solution has at least the following beneficial effects: During production, the connection pins are directly integrally connected to the bottom cover, and there is no need to design a structure for installing and fastening the connection pins inside the bottom cover or the box body. During overall assembly, it is also not necessary to individually install the connection pins into the bottom cover for fixation. Only need to connect the circuit board to the top side of the bottom cover, and then connect the bottom cover to the bottom of the box body, and use the bottom cover to cover and seal the internal cavity of the box body to complete the overall assembly. At this time, the multiple jacks on the top side of the box body can be used for plugging in external plugs, and the multiple connection pins exposed on the bottom side of the bottom cover can be used for connecting external connectors. Therefore, the adapter plug of the utility model has a simpler structure, can improve the efficiency during its production and assembly, and has stronger practicability.

[0007] As a further improvement to the above technical solution, a limit frame is connected to the top side of the bottom cover. A mounting hole is provided on the bottom cover directly opposite the limit frame. The top of the connecting leg extends through the mounting hole into the limit frame, and the connecting head protrudes upward from the limit frame. When the connecting leg is integrally connected to the bottom cover, the top of the connecting leg extends through the mounting hole into the limit frame. The limit frame further defines the position of the connecting leg, improving its structural stability during installation and use. The connecting head protrudes upward from the limit frame to connect to the circuit board.

[0008] As a further improvement to the above technical solution, a support piece is connected to the inner side of the mounting hole on the bottom cover, and the connector is located on the top side of the support piece. The bottom cover has a support piece that supports and positions the connector. When installing the connecting pin, the connecting pin is inserted into the mounting hole at an angle, so that the connector first passes through the mounting hole and then the connecting pin is aligned. At this time, the connector moves to the top side of the support piece. Because the support piece supports the connector, the stability of the connector when electrically connecting it to the circuit board is improved, and the overall structure is more compact.

[0009] As a further improvement to the above technical solution, the top side of the bottom cover is connected to a boss, and the top side of the boss is formed with an upwardly extending protrusion, the outer diameter of the protrusion is smaller than the outer diameter of the boss, and there are multiple protrusions. Positioning holes are respectively provided at positions on the circuit board opposite the multiple protrusions, and the multiple protrusions respectively pass through the multiple positioning holes. The smaller outer diameter protrusion and the larger outer diameter boss form an annular positioning step, and the multiple positioning steps can form a supporting surface. When installing the circuit board, the multiple positioning holes on the circuit board are aligned with the multiple protrusions, and the circuit board is then placed on the supporting surface, thereby achieving rapid installation and positioning of the circuit board.

[0010] As a further improvement to the above technical solution, the top side of the circuit board is connected to the lamp body, and the inner top side of the box body is connected to a light guide. A light exit hole is provided on the top side of the box body directly opposite the light guide, and the bottom end of the light guide extends downward until it contacts the lamp body. During operation, the lamp body transmits light outward through the light exit hole through the light guide. The light guide transmits light, improving the uniformity of the light emitted by the lamp body. The user can usually judge the status of the conversion plug by observing the changes in the light, thus improving the user experience.

[0011] As a further improvement to the above technical solution, a hole is formed on one side of the box body, a button is connected to the box body at the position of the hole, and a push switch is connected to the circuit board next to the button, with the trigger end of the push switch abutting against the button. The circuit board also has a push switch that controls the entire circuit. During use, the push switch is turned on and off by pressing the button against the trigger end of the push switch.

[0012] As a further improvement of the above technical solution, an upper elastic sheet and a lower elastic sheet are connected to one side of the key located inside the box body. The upper elastic sheet is connected to the inner side of the box body, and the lower elastic sheet is connected to the top side of the bottom cover. When it is necessary to open or close the push switch, when the user presses the key into the box body, the key drives the upper elastic sheet and the lower elastic sheet to undergo elastic deformation, so that the key displaces into the box body and acts on the trigger end of the push switch. When the pressure on the key is removed, the upper elastic sheet and the lower elastic sheet elastically recover, thereby driving the key to reset. In this way, the use experience of the key can be improved.

[0013] As a further improvement of the above technical solution, an upper card slot with a downward-facing notch is provided on the inner side of the box body, and a lower card slot with an upward-facing notch is provided on the top side of the bottom cover. The upper elastic sheet is inserted into the upper card slot, and the lower elastic sheet is inserted into the lower card slot. When installing the key, first install the key into the box body. The top end of the upper elastic sheet is inserted into the upper card slot for positioning, and the key protrudes out of the box body from the hole, realizing the preliminary positioning of the key. When installing the bottom cover, align the lower elastic sheet with the lower card slot on the top side of the bottom cover, and insert the bottom end of the lower elastic sheet into the lower card slot, thereby firmly positioning the key in the box body.

[0014] As a further improvement of the above technical solution, a positioning step is provided on the inner side of the bottom of the box body, and a sealing ring is provided between the top side of the bottom cover and the positioning step. When installing the bottom cover, the bottom cover can be inserted into the box body. Through the limitation of the bottom cover by the positioning step, the quick installation of the bottom cover can be realized, and the sealing ring between the top side of the bottom cover and the positioning step can greatly enhance the sealing performance of the connection between the two.

[0015] As a further improvement of the above technical solution, the bottom cover and the box body are ultrasonically welded. The ultrasonic welding between the bottom cover and the box body can improve the sealing performance between the bottom cover and the box body and improve the overall appearance.

[0025] Refer to Figure 1 And Figure 2, A conversion plug, comprising a bottom cover 100, connecting pins 200, a circuit board 300 and a box body 400. Among them, the connecting pins 200 are integrally connected to the bottom side of the bottom cover 100. When the bottom cover 100 is made of plastic, the connecting pins 200 can be injected into the bottom cover 100 by insert molding. A connecting head 210 is formed at the top end of the connecting pin 200, and the connecting head 210 extends upward out of the bottom cover 100. The number of the connecting pins 200 is multiple. For example, the number of the connecting pins 200 is three, and the three connecting pins 200 are arranged in a triangular shape on the bottom cover 100. And the shapes of the three connecting pins 200 can be the same or different. For example, two of the connecting pins 200 are sheet-shaped and one connecting pin 200 is column-shaped; The circuit board 300 is connected to the top side of the bottom cover 100, and the connecting head 210 is electrically connected to the circuit board 300; The box body 400 is provided with a plurality of jacks 410 on the top side. An opening-down cavity is formed by enclosing inside the box body 400. The bottom cover 100 is connected to the bottom of the box body 400 and covers the cavity.

[0026] As can be seen from the above, during production, the connecting pins 200 are directly integrally connected to the bottom cover 100, and there is no need to design a structure for installing and fastening the connecting pins 200 inside the bottom cover 100 or the box body 400. During overall assembly, there is no need to install the connecting pins 200 onto the bottom cover 100 one by one for fixation either. Only need to connect the circuit board 300 to the top side of the bottom cover 100, and then connect the bottom cover 100 to the bottom of the box body 400, and use the bottom cover 100 to cover and seal the internal cavity of the box body 400, then the overall assembly can be completed. At this time, the plurality of jacks 410 on the top side of the box body 400 can be used for plugging of external plugs, and the plurality of connecting pins 200 exposed on the bottom side of the bottom cover 100 can be used for connecting external connectors. Therefore, the conversion plug of the present utility model has a simpler structure, can improve the production and assembly efficiency, and has stronger practicability.

[0027] In order to realize the functions of the conversion plug itself, a plurality of wiring terminals are naturally connected to the circuit board 300. At this time, the number of the jacks 410 on the top side of the box body 400 is the same as the number of the wiring terminals, and the plurality of wiring terminals are respectively opposite to the plurality of jacks 410. In practical applications, according to different types of plugs to be powered, the shapes of the wiring terminals can also be designed differently. For example, two of the wiring terminals respectively include two power connection clip pieces connected to the circuit board 300, and the two power connection clip pieces are abutted against each other to clamp the inserted power connection piece, while one wiring terminal is a conductive piece connected to the circuit board 300. In order to improve the anti-deformation ability of the conductive piece, the conductive piece can be designed in a wavy shape along the up and down direction.

[0028] Due to the limited thickness of the bottom cover 100 itself, especially when the bottom cover 100 is relatively thin, the connecting feet 200 are injected into the bottom cover 100 by insert molding. The contact area between the two is small, and the stability is poor after being connected integrally. In order to make the connecting feet 200 not easily separated from the bottom cover 100, the connecting feet 200 can be bent to increase the contact area with the bottom cover 100. In this embodiment, a limiting frame 110 is connected to the top side of the bottom cover 100, and a mounting hole 120 is provided at a position on the bottom cover 100 opposite to the limiting frame 110. The top of the connecting foot 200 extends into the limiting frame 110 through the mounting hole 120, and the connecting head 210 protrudes upward from the limiting frame 110. When the connecting foot 200 is integrally connected to the bottom cover 100, the top of the connecting foot 200 is inserted into the limiting frame 110 through the mounting hole 120. The position of the connecting foot 200 can be further limited by the limiting frame 110, improving the structural stability during installation and use. The connecting head 210 protrudes upward from the limiting frame 110 to be connected to the circuit board 300.

[0029] In the above embodiment, the size of the mounting hole 120 can be the same as the sectional space formed by surrounding the limiting frame 110. In order to further improve the structural stability of the connecting feet 200 during installation and use, as Figure 3 shown, in this embodiment, a support piece 130 is connected to the inner side of the mounting hole 120 on the bottom cover 100, and the connecting head 210 is located on the top side of the support piece 130. There is a support piece 130 on the bottom cover 100 for supporting and positioning the connecting head 210. When installing the connecting feet 200, the connecting feet 200 are obliquely inserted upward into the mounting hole 120, so that the connecting head 210 first passes through the mounting hole 120 and then the connecting feet 200 are straightened. At this time, the connecting head 210 moves to the top side of the support piece 130. Due to the support of the support piece 130 for the connecting head 210, the stability when electrically connecting the connecting head 210 to the circuit board 300 can be improved, and the overall structure is more compact.

[0030] The circuit board 300 can be directly installed and fixed on the top side of the bottom cover 100. When there are raised structures such as a limiting frame 110 on the top side of the bottom cover 100, a structure for positioning the circuit board 300 can be formed on the top side of the bottom cover 100. Specifically, a boss 141 is connected to the top side of the bottom cover 100, and a convex column 142 extending upward is formed on the top side of the boss 141. The outer diameter of the convex column 142 is smaller than the outer diameter of the boss 141. There are multiple bosses 141. Positioning holes are respectively provided at positions on the circuit board 300 opposite to the multiple convex columns 142. The multiple convex columns 142 respectively pass through the multiple positioning holes. For example, there are four bosses 141, and the four bosses 141 are arranged in a rectangle at the four corner positions on the top side of the bottom cover 100, so as to facilitate the stable positioning of the entire circuit board 300. The convex column 142 with a smaller outer diameter and the boss 141 with a larger outer diameter form an annular positioning step, and multiple positioning steps can form a supporting surface. When installing the circuit board 300, align the multiple positioning holes on the circuit board 300 with the multiple convex columns 142 respectively, and then place the circuit board 300 on the supporting surface, so as to realize the rapid installation and positioning of the circuit board 300.

[0031] In some embodiments, a lamp body 310 is connected to the top side of the circuit board 300, a light guide body 420 is connected to the inner top side of the box body 400, a light outlet hole is provided at a position on the top side of the box body 400 opposite to the light guide body 420, and the bottom end of the light guide body 420 extends downward to abut against the lamp body 310. In practical applications, an installation groove can be provided on the inner top side of the box body 400, and a positioning section is provided at the top of the light guide body 420. The shape of the positioning section is adapted to the shape of the installation groove, so that the light guide body 420 can be quickly installed and positioned on the inner top side of the box body 400, and a light outlet hole is provided at the bottom of the installation groove, and the top end of the light guide body 420 is inserted into the light outlet hole. During operation, the lamp body 310 can transmit light outward through the light guide body 420 from the light outlet hole, and the light guide body 420 is used to conduct the light, improving the uniformity of the light emitted by the lamp body 310 outward. Users usually judge the change of the light to know the use state of the conversion plug, improving the use experience.

[0032] In order to enrich the overall use function, the entire conversion plug can be designed to be integrally switchable. Specifically, an opening is provided on one side of the box body 400, a key 430 is connected at a position in the box body 400 corresponding to the opening, and a push switch 320 is connected to the circuit board 300 beside the key 430. The trigger end of the push switch 320 abuts against the key 430. There is also a push switch 320 on the circuit board 300 for controlling the on-off of the entire circuit. During use, by pressing the key 430 against the trigger end of the push switch 320, the opening and closing of the push switch 320 can be realized.

[0033] In the above embodiment, the button 430 can be made of an elastic material or a softer material. When the button 430 is pressed, the button 430 itself directly undergoes elastic deformation to counteract the trigger end of the push switch 320. However, at this time, the button 430 has a poor ability to automatically reset during use. To improve the user experience of the button 430, in this embodiment, an upper elastic sheet 431 and a lower elastic sheet 432 are connected to one side of the button 430 located inside the box body 400. The upper elastic sheet 431 is connected to the inner side of the box body 400, and the lower elastic sheet 432 is connected to the top side of the bottom cover 100. When it is necessary to open or close the push switch 320, when the user presses the button 430 into the box body 400, the button 430 drives the upper elastic sheet 431 and the lower elastic sheet 432 to undergo elastic deformation, so that the button 430 displaces into the box body 400 and acts on the trigger end of the push switch 320. When the pressure on the button 430 is removed, the upper elastic sheet 431 and the lower elastic sheet 432 elastically recover, thereby driving the button 430 to reset. In this way, the user experience of the button 430 can be improved.

[0034] There are various structural forms of the upper elastic sheet 431 and the lower elastic sheet 432. For example, the upper elastic sheet 431 can be a sheet-like structure that directly extends upward from the top side of the button 430, and the lower elastic sheet 432 can also be a sheet-like structure that directly extends downward from the bottom side of the button 430, or it can be a rod-like structure that extends horizontally. The two ends of the rod-like structure are bent upward respectively, and then the two bent top ends are bent again in a manner of approaching each other, and finally connected to the left and right sides of the button 430. In this way, the lower elastic sheet 432 forms a stable support structure, increasing the position and area of connection and support, and making the structure of the button 430 more stable.

[0035] For the installation and fixation of the upper elastic sheet 431 and the lower elastic sheet 432, the upper elastic sheet 431 and the lower elastic sheet 432 can be directly fixed to the inner side of the box body 400. In order to further improve the overall installation efficiency, in this embodiment, an upper card slot with a downward-facing notch is provided on the inner side of the box body 400. It can be a rib protruding from the inner side of the box body 400, forming an upper card slot with the inner side wall of the box body 400. A lower card slot 150 with an upward-facing notch is provided on the top side of the bottom cover 100. Similarly, it can be a rib protruding from the top side of the bottom cover 100, forming a lower card slot 150 with the side wall of the bottom cover 100. The upper elastic sheet 431 is inserted into the upper card slot, and the lower elastic sheet 432 is inserted into the lower card slot 150. When installing the button 430, the button 430 is first installed into the box body 400. The top end of the upper elastic sheet 431 is inserted into the upper card slot for positioning, and the button 430 protrudes outward from the box body 400 through the hole, realizing the preliminary positioning of the button 430. When installing the bottom cover 100, the lower elastic sheet 432 is aligned with the lower card slot 150 on the top side of the bottom cover 100, and the bottom end of the lower elastic sheet 432 is inserted into the lower card slot 150, thereby firmly positioning the button 430 within the box body 400.

[0036] An outwardly protruding outer edge can be formed on the outer side of the bottom cover 100. During connection, it is connected to the bottom side of the box body 400 through the outer edge, or the bottom cover 100 is inserted into the box body 400 to reduce the exposure of the connection structure between the two. However, in this case, a structure for positioning the bottom cover 100 needs to be provided inside the box body 400. Specifically, a positioning step is provided on the inner side of the bottom of the box body 400. A sealing ring is provided between the top side of the bottom cover 100 and the positioning step. In practical applications, a sealing groove can also be provided near the outer edge on the top side of the bottom cover 100 to position the sealing ring within the sealing groove, which can not only facilitate the positioning of the sealing ring but also make the overall structure more compact. When installing the bottom cover 100, the bottom cover 100 can be inserted into the box body 400. Through the limitation of the bottom cover 100 by the positioning step, the quick installation of the bottom cover 100 can be achieved, and the sealing ring between the top side of the bottom cover 100 and the positioning step can greatly enhance the sealing performance of the connection between the two.

[0037] For the mutual connection between the bottom cover 100 and the box body 400, it can be through snap connection, or through fixing and connecting with connecting parts such as screws and rivets. In this embodiment, the bottom cover 100 and the box body 400 are ultrasonically welded. The ultrasonic welding between the bottom cover 100 and the box body 400 can improve the sealing performance between the bottom cover 100 and the box body 400 and improve the overall appearance.

[0038] The above has specifically described the preferred embodiments of the present utility model, but the present invention is not limited to the described embodiments. Those skilled in the art can also make various equivalent modifications or substitutions without departing from the spirit of the present utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
