Description

Technical Field

[0001] The present application relates to the technical field of conversion sockets, and in particular to a small conversion socket. Background Art

[0002] A converter, also known as a travel adapter or power adapter, is a device used to convert the shape or size of a plug to accommodate outlet standards in different countries and regions. Because voltages and outlet types vary across the world, converters are essential when traveling internationally or using appliances from different countries.

[0003] The existing Chinese patent with publication number CN218242498U discloses a built-in conversion socket structure, which includes a steering socket, a connecting socket embedded in the upper end of the steering socket, and a bidirectional socket embedded in one side of the steering socket.

[0004] The above-mentioned conversion socket combines a steering socket, a connecting socket, and a bidirectional socket to achieve the effect of multi-standard interchangeable plugs. However, the above-mentioned conversion socket has some disadvantages, such as: the existing conversion socket is large in size, inconvenient to carry and use, and needs to be improved. Utility Model Content

[0005] The purpose of this application is to provide a small conversion socket for the convenience of carrying the conversion socket.

[0006] A small conversion socket provided in the present application adopts the following technical solution: it includes a shell, a circuit module is connected to the shell, one end of the shell is provided with a socket pin, the socket pin is connected to the circuit module, and the other end of the shell is provided with an installation cavity corresponding to the circuit module, and the end of the shell close to the opening of the installation cavity is provided with a thin edge.

[0007] By adopting the above technical solution, one end of the shell is provided with a thin edge, which can reduce the volume of the conversion socket and the weight of the conversion socket, making it easier to carry.

[0008] Optionally, the circuit module includes a circuit board, a clamping member connected to the circuit board, and a grounding spring connected to the housing, the socket pins are connected to the circuit board, and the circuit board is provided with a first through hole corresponding to the socket pins.

[0009] By adopting the above technical solution, the external pin passes through the first through hole and abuts against the socket pin, and the clamping member clamps the external pin, thereby improving the stability of the external pin when installed on the conversion socket.

[0010] Optionally, the clamping member includes a connecting plate and two elastic plates connected to the connecting plate, and a clamping groove is formed between the two elastic plates.

[0011] By adopting the above technical solution, when the external pin passes through the clamping groove, the external pin drives the two elastic plates to move away from each other. The two elastic plates are subjected to force to produce elastic deformation and maintain a tendency to elastically reset. The two elastic plates clamp the external pin, thereby improving the stability of the external pin installed on the conversion socket.

[0012] Optionally, the sides of the two elastic plates facing each other are in the shape of inner arc surfaces.

[0013] By adopting the above technical solution, one side of the elastic plate is in the shape of an inner arc surface, which increases the contact area between the external pin and the elastic plate, increases the friction between the external pin and the elastic plate, and makes the external pin more stable in the clamped state and not easy to move.

[0014] Optionally, a first guide surface is provided on one side of the two elastic plates facing each other, and the first guide surface is located at an end of the elastic plate away from the circuit board.

[0015] By adopting the above technical solution, when the external pin is installed in the conversion socket, the external pin is movably abutted against the first guide surface, and the first guide surface guides the movement of the external pin, so that the external pin passes through the clamping groove smoothly, thereby improving the efficiency of the external pin installation.

[0016] Optionally, the circuit board is connected to a mounting block, the mounting block is provided with a mounting groove for the clamping member to be clamped in, and the mounting block is provided with a second through hole corresponding to the first through hole.

[0017] By adopting the above technical solution, the clamping member is inserted into the mounting groove, and the outer surface of the clamping member fits against the inner wall of the mounting groove. The inner wall of the mounting groove limits the horizontal movement of the clamping member, thereby improving the stability of the clamping member installed on the circuit board.

[0018] Optionally, the clamping member is connected to a positioning block, the mounting block is provided with a first positioning groove for the positioning block to pass through, and the circuit board is provided with a second positioning groove for the positioning block to pass through.

[0019] By employing this technical solution, the positioning block snaps into the first and second positioning slots, positioning the clamp for installation, ensuring the clamp is precisely positioned. The outer surface of the positioning block mates with the inner walls of the first and second positioning slots, indirectly increasing the contact area between the mounting block, the circuit board, and the clamp, increasing friction and improving the stability of the clamp installed on the circuit board.

[0020] Optionally, the mounting block is connected to a baffle, the mounting block is located between the circuit board and the baffle, the baffle is provided with a third through hole corresponding to the second through hole, the baffle is slidably connected to a cover plate for covering the third through hole, the cover plate is connected to the baffle through an elastic member, and a second guide surface is provided on the side of the cover plate away from the mounting block.

[0021] By adopting the above technical solution, the baffle restricts the movement of the clamping member within the mounting slot, thereby improving the stability of the clamping member installed on the circuit board and preventing the clamping member from dislodging from the mounting slot. When the external pin is not inserted into the conversion socket, the cover plate covers the third through-hole, thereby reducing the adhesion of dust to the circuit board through the third through-hole. When the external pin is inserted into the conversion socket, it abuts the second guide surface, causing the cover plate to slide. The elastic member is elastically deformed under force, causing the cover plate to maintain its elastic reset tendency. The external pin is clamped between the cover plate and the inner wall of the third through-hole, thereby improving the stability of the external pin installed on the conversion socket.

[0022] Optionally, the baffle is provided with a guide block, the cover plate is provided with a guide groove for slidingly cooperating with the guide block, one end of the elastic member is connected to the guide block, and the other end is connected to the inner wall of the guide groove.

[0023] By adopting the above technical solution, when the cover plate slides, the sliding cooperation of the guide block and the guide groove plays a role in guiding and limiting the sliding of the cover plate, thereby improving the sliding stability of the cover plate.

[0024] Optionally, the shell includes an outer shell and an inner shell connected to the outer shell, the outer shell and the inner shell are connected by a snap-fit structure, the mounting cavity is provided on the outer shell, the inner shell covers the circuit board and abuts against the baffle, and the inner shell is provided with a fourth through hole corresponding to the third through hole.

[0025] By adopting the above technical solution, the inner shell abuts against the baffle, and the inner shell restricts the vertical movement of the circuit board, mounting block, baffle and cover plate, thereby improving the stability of the circuit board, mounting block, baffle and cover plate installed in the mounting cavity, and preventing the circuit board, mounting block, baffle and cover plate from escaping from the mounting cavity.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. One end of the shell is set with a thin edge, which can reduce the volume of the conversion socket and reduce the weight of the conversion socket, making it easy to carry.

[0028] 2. The baffle restricts the movement of the clamping member within the mounting slot, thereby improving the stability of the clamping member installed on the circuit board and preventing the clamping member from detaching from the mounting slot. When the external pin is not inserted into the conversion socket, the cover plate covers the third through-hole, thereby reducing the adhesion of dust to the circuit board through the third through-hole. When the external pin is inserted into the conversion socket, the external pin abuts the second guide surface, causing the external pin to slide the cover plate. The elastic member is subjected to force and elastic deformation, causing the cover plate to maintain an elastic reset tendency. The external pin is clamped by the cover plate and the inner wall of the third through-hole, thereby improving the stability of the external pin installed on the conversion socket.

[0044] The following is combined with Figure 1 -Attached Figure 14 This application is described in further detail.

[0045] The embodiment of the present application discloses a small conversion socket.

[0046] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the housing 1 comprises an outer shell 11 and an inner shell 12 connected to the outer shell 11. A mounting cavity 111 is defined at one end of the outer shell 11, within which a circuit module 2 is connected. The circuit module 2 comprises a circuit board 21 mounted within the mounting cavity 111, two clamping members 22 detachably connected to the circuit board 21, and a grounding spring 23 connected to the outer shell 11.

When the grounding spring 23 and the inner shell 12 are both installed on the outer shell 11, the grounding spring 23 is clamped by the outer shell 11 and the inner shell 12. The outer shell 11 and the inner shell 12 are both thin-edged at one end away from the socket pin 211. The outer shell 11 and the inner shell 12 are connected by a snap-fit structure 3. The snap-fit structure 3 includes a snap-fit block 31 provided on the outer shell 11 and a snap-fit groove 32 for snapping into engagement with the snap-fit block 31.

There are four snap-fit blocks 31 (the number of snap-fit blocks 31 is selected according to actual needs), and the four snap-fit blocks 31 are evenly distributed around the axis of the outer shell 11.

[0048] Combine Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown, the circuit board 21 has two first through holes 212 corresponding to the socket pins 211. Two mounting blocks 4 are detachably connected to the side of the circuit board 21 away from the socket pins 211. The two mounting blocks 4 are connected by a connecting rod 41, and the two mounting blocks 4 and the connecting rod 41 are integrally formed. Each mounting block 4 is fixedly connected to a fixing post 42 on the side close to the circuit board 21. The fixing post 42 is integrally formed with the mounting block 4. The circuit board 21 has a fixing slot 213 for mating with the fixing post 42.

The facing sides of the two elastic plates 222 are each provided with a first guide surface 224, which is located at the end of the elastic plate 222 away from the circuit board 21. A positioning block 225 is fixedly connected to the side of each connecting plate 221 near the circuit board 21. The positioning block 225 is integrally formed with the connecting plate 221. The mounting block 4 defines a first positioning slot 45 for the corresponding positioning block 225 to pass through. The circuit board 21 defines a second positioning slot 214 for the corresponding positioning block 225 to pass through. The first positioning slot 45 corresponds to the second positioning slot 214.

The external pin passes through the third through hole 52, the clamping groove 223, the second through hole 44 and the first through hole 212 in sequence, and abuts against the corresponding socket pin 211. When the external pin passes through the clamping groove 223, the two elastic plates 222 are subjected to elastic deformation and maintain the tendency of elastic reset. The two elastic plates 222 clamp the external pin, thereby realizing the installation of the external pin.
