[0002] The circuit board is an important component of electrical components such as circuit breakers. The plugs on it are used to connect to external sockets to achieve circuit connection and signal transmission.

[0003] Traditional circuit breaker circuit board plugs are usually connected to the socket by plugging. During use, if there is external vibration, the connection may be unstable, affecting the reliability of the circuit connection and the performance of the equipment.

[0004] Therefore, a circuit board insert is now proposed. Utility Model Content

[0005] In order to improve the problem that traditional circuit breaker circuit board plugs are usually connected to the socket in a plug-in manner, and in the process of use, when external vibration occurs, the connection may be unstable, affecting the reliability of the circuit connection and the performance of the equipment, the utility model provides a circuit board plug.

[0006] The utility model provides a plug-in sheet for a circuit board, which adopts the following technical solution:

[0007] A plug for a circuit board includes a socket connection end, a circuit board connection end, and two connecting strips fixedly installed between the socket connection end and the circuit board connection end. A connecting plate is also fixedly installed between the socket connection end and the circuit board connection end. The connecting plate is located between the two connecting strips, and a gap is formed between the connecting plate and the two connecting strips. A connection hole is provided on the socket connection end, and a limit portion is stamped on both sides of the socket connection end. The two limit portions are respectively located at the ends of the two gaps.

[0008] By adopting the above technical solution, a connection hole is opened on the socket connection end. When in use, the connection hole is used for the protrusion on the socket to extend into, so as to achieve a stable connection between the socket connection end and the socket, so that the socket connection end is not likely to fall off from the socket.

[0009] Optionally, a through hole is provided at the connection end of the circuit board.

[0010] By adopting the above technical solution, the connection and fixation between the circuit board connection end and the circuit board can be achieved by passing a bolt or the like through the through hole and threading it with the circuit board.

[0011] Optionally, positioning blocks are fixedly connected to the connection end surface of the circuit board on both sides of the through hole.

[0012] By adopting the above technical solution, the positioning block is set by providing corresponding positioning grooves on both sides of the threaded hole on the circuit board. When connecting the circuit board connection end to the circuit board, the positioning block on the circuit board connection end is inserted into the corresponding positioning groove on the circuit board, so that the through hole and the threaded hole can be aligned, which facilitates the connection. Moreover, the positioning block also plays a limiting role, preventing the bolt from driving the entire insert to rotate during the process of screwing in the bolt, thereby facilitating the connection between the socket connection end on the insert and the socket.

[0013] Optionally, a plurality of oblique supports are fixedly installed between the connecting plate and the connecting bar, and a stable triangular structure is formed between the oblique supports, the connecting plate and the connecting bar.

[0014] By adopting the above technical solution, the multiple oblique supports and the triangular stable structure formed improve the anti-extrusion deformation effect of the side of the insert, thereby facilitating the structural integrity of the insert.

[0015] Optionally, a reinforcement assembly is fixedly installed on the connecting plate, and the reinforcement assembly includes two symmetrically arranged reinforcement plates and an intermediate plate fixedly installed between the two reinforcement plates. A strip hole is opened in the middle of the connecting plate, and the intermediate plate passes through the interior of the strip hole.

[0016] By adopting the above technical solution and arranging a reinforcement component on the connecting plate, the bending resistance of the entire insert is improved, thereby facilitating use and carrying.

[0017] Optionally, mounting grooves are provided on both sides of the connecting plate, and the reinforcing plate is fixedly installed inside the mounting grooves.

[0018] By adopting the above technical solution, this structural design allows the upper surface of the reinforcement plate to be on the same plane as the upper and lower surfaces of the socket connection end and the circuit board connection end, thereby improving the overall aesthetic effect.

[0019] Optionally, a rubber sleeve is fixedly installed inside the connecting hole.

[0020] By adopting the above technical solution, the rubber sleeve makes the connection more compact and stable when the protrusion on the socket is inserted into the connection hole.

[0021] Optionally, the socket connection end, the circuit board connection end, the connection strip and the connection plate are designed as an integrated structure.

[0022] By adopting the above technical solution, this structural design improves the connection strength between the socket connection end, the circuit board connection end, the connection strip and the connection plate.

[0023] In summary, the present invention has the following beneficial effects:

[0024] 1. The present invention provides a connection hole on the socket connection end. When in use, the connection hole is used for the protrusion on the socket to extend into, thereby achieving a stable connection between the socket connection end and the socket, thereby preventing the socket connection end from falling out of the socket. In addition, a limit portion is stamped and formed on both sides of the socket connection end. The limit portion can abut against the socket to control the insertion depth between the socket connection end and the socket;

[0025] 2. In order to improve the deformation resistance of the entire insert side, the utility model has several oblique supports fixedly installed between the connecting plate and the connecting strip. A stable triangular structure is formed between the oblique supports, the connecting plate and the connecting strip, which is conducive to ensuring the structural integrity of the insert. Moreover, in order to improve the bending resistance of the entire insert, a reinforcement component is fixedly installed on the connecting plate, which makes it less likely for the insert to bend during carrying or installation, and is conducive to installation and use.

[0031] The following is in conjunction with the appended drawings in the embodiment of the present utility model. Figure 1-3 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0032] Please refer to Figure 1-3A plug-in for a circuit board includes a socket connection end 1, a circuit board connection end 2, and two connecting strips 3 fixedly installed between the socket connection end 1 and the circuit board connection end 2. The circuit board connection end 2 is provided with a through hole 8. By passing a bolt or the like through the through hole 8 and threading it with the circuit board, the connection and fixation between the circuit board connection end 2 and the circuit board can be achieved. Positioning blocks 9 are fixedly connected to both sides of the through hole 8 on the surface of the circuit board connection end 2. The positioning blocks 9 are provided by providing corresponding positioning grooves on both sides of the threaded hole on the circuit board. When connecting the circuit board connection end 2 to the circuit board, the positioning blocks 9 on the circuit board connection end 2 are inserted into the corresponding positioning grooves on the circuit board to align the through hole 8 with the threaded hole, thereby facilitating connection. Moreover, the positioning blocks 9 also serve as a limiter, preventing the bolt from driving the entire plug-in to rotate during the process of screwing in the bolt, thereby facilitating the connection between the socket connection end 1 on the plug-in and the socket.

[0033] Reference Figure 1-3 A connecting plate 4 is fixedly mounted between the socket connection 1 and the circuit board connection 2. It is located between the two connecting bars 3. This plate 4 compensates for the insufficient strength of the connecting bars 3 and improves the bending resistance of the entire plug. The socket connection 1, circuit board connection 2, connecting bar 3, and connecting plate 4 are designed as an integrated structure. This design improves the connection strength between the socket connection 1, circuit board connection 2, connecting bar 3, and connecting plate 4. The socket connection 1, circuit board connection 2, connecting bar 3, and connecting plate 4 are all made of brass, which helps improve the conductivity of the entire plug. Furthermore, the entire plug surface can be tinned to improve the corrosion resistance of the entire plug. A gap 5 is formed between the connecting plate 4 and the two connecting bars 3. Several oblique supports 10 are fixedly installed between the connecting plate 4 and the connecting bar 3. The oblique supports 10 are located inside the gap 5. A stable triangular structure is formed between the oblique supports 10 and the connecting plate 4 and the connecting bar 3. The multiple oblique supports 10 and the triangular stable structure formed improve the anti-extrusion deformation effect of the side of the insert, which is conducive to ensuring the structural integrity of the insert.

[0034] Reference Figure 1-3A reinforcement assembly is fixedly installed on the connecting plate 4. The reinforcement assembly includes two symmetrically arranged reinforcement plates 11 and an intermediate plate 12 fixedly installed between the two reinforcement plates 11. A strip hole 13 is opened in the middle of the connecting plate 4, and the intermediate plate 12 runs through the interior of the strip hole 13. The intermediate plate 12 and the reinforcement plate 11 are both made of aluminum alloy material, and an I-shaped structure is formed between the two reinforcement plates 11 and the intermediate plate 12. By arranging the reinforcement assembly on the connecting plate 4, the bending resistance of the entire plug is improved, thereby facilitating use and carrying. Mounting slots 14 are opened on both sides of the connecting plate 4, and the reinforcement plate 11 is fixedly installed inside the mounting slots 14. This structural design ensures that the upper surface of the reinforcement plate 11 and the upper and lower surfaces of the socket connection end 1 and the circuit board connection end 2 remain on the same plane, improving the overall aesthetic effect.

[0035] Reference Figure 1-3 The socket connection end 1 is provided with a connection hole 6 for the socket protrusion to extend into, achieving a stable connection between the socket connection end 1 and the socket. A rubber sleeve 15 is fixedly installed inside the connection hole 6, which ensures a more compact and stable connection when the socket protrusion is inserted into the connection hole 6. A stopper 7 is stamped into each side of the socket connection end 1. The two stoppers 7 are located at the ends of the two gaps 5, respectively. The stoppers 7 can abut against the socket to control the insertion depth between the socket connection end 1 and the socket.

[0036] The implementation principle of the present invention is as follows: a connection hole 6 is provided on the socket connection end 1. When in use, the connection hole 6 is used for the projection on the socket to extend into, so as to achieve a stable connection between the socket connection end 1 and the socket, so that the socket connection end 1 is not easily detached from the socket. Moreover, a rubber sleeve 15 is fixedly installed inside the connection hole 6. The rubber sleeve 15 makes the connection more compact and stable when the projection on the socket is inserted into the connection hole 6. In addition, a limiting portion 7 is stamped and formed on both sides of the socket connection end 1. The limiting portion 7 can be abutted against the socket to control the insertion depth between the socket connection end 1 and the socket. At the same time, a through hole 8 is provided on the circuit board connection end 2. By passing a bolt or the like through the through hole 8, Hole 8, and threaded connection with the circuit board, the connection and fixation between the circuit board connection end 2 and the circuit board can be achieved. In addition, the surface of the circuit board connection end 2 is located on both sides of the through hole 8 and is fixedly connected with positioning blocks 9. The positioning blocks 9 are set by providing corresponding positioning grooves on both sides of the threaded hole on the circuit board. When connecting the circuit board connection end 2 to the circuit board, the positioning blocks 9 on the circuit board connection end 2 are inserted into the corresponding positioning grooves on the circuit board, so that the through hole 8 and the threaded hole can be aligned, which is convenient for connection. Moreover, the positioning blocks 9 also play a role of limiting, which prevents the bolt from driving the entire insert to rotate during the process of screwing in the bolt, thereby facilitating the connection between the socket connection end 1 on the insert and the socket;

[0037] Moreover, further, in order to improve the deformation resistance of the side of the entire insert, a number of inclined supports 10 are fixedly installed between the connecting plate 4 and the connecting strip 3, and a stable triangular structure is formed between the inclined supports 10 and the connecting plate 4 and the connecting strip 3, which is conducive to ensuring the structural integrity of the insert; in order to improve the bending resistance of the entire insert, a reinforcing component is fixedly installed on the connecting plate 4, which makes it less likely for the insert to bend during carrying or installation, and is conducive to installation and use.
