[0027] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present utility model.

[0028] It should be noted that: similar reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0029] This embodiment mainly elaborates on the title of the circuit board with a fast circuit connection structure, as follows:

[0030] Main solution :

[0031] Circuit board with a fast circuit connection structure, referring to the attached Figures 1 - 7, including a circuit board body 10 with a circuit inside. There is at least one through hole 101 on the circuit board body 10 that can conduct through the side wall. A stepped socket 20 is inserted at the through hole 101. There is a jack 202 in the middle of the socket 20, and a wiring terminal 30 is inserted into the jack 202. At least one convex portion 1011 made of copper for conducting circuit contacts is provided on the side wall of the jack 202. At least one U-shaped opening is provided on the socket 20 to form a U-shaped plate 201. Convex points 2011 are provided on both the inner wall and the outer wall of the U-shaped plate 201. The convex points 2011 are convex platforms. A abutting convex platform 301 is provided on the side wall of the wiring terminal 30. When the socket 20 is inserted, the convex portion 1011 squeezes the convex point 2011 on the outer wall of the U-shaped plate 201 to make the U-shaped plate 201 flip inward. After being completely inserted, the convex portion 1011 contacts and is located above the convex point 2011. When the wiring terminal 30 is inserted, the abutting convex platform 301 squeezes the convex point 2011 on the inner wall of the U-shaped plate 201 to make the U-shaped plate 201 flip outward. After being completely inserted, the abutting convex platform 301 contacts and is located below the convex point 2011 on the inner wall of the U-shaped plate 201. In this solution, two vertical limits are formed between the socket 20 and the convex portion 1011 on the circuit board and between the abutting convex platform 301 of the socket 20 and the wiring terminal 30 through the extrusion in the horizontal direction after installation, so that the three are in a stable state. In addition, the mutually abutting structure also conducts the circuit while limiting. This structure has the advantages of convenient installation, detachable, replaceable, and easy to repair.

[0032] Circuit board part :

[0033] As Figures 1 - 3 shown, a copper plating layer that conducts with the circuit in the circuit board is provided on the side wall of the through hole 101 and the surface of the convex portion 1011. In this solution, the copper plating layer is used to increase the conduction area on its surface, and multiple positions can be set on the socket 20 for conducting the circuit to improve its conduction rate.

[0034] Socket part :

[0035] As Figures 4 - 7 shown, the socket 20 has a stepped structure, and the width of the first-level step at its bottom is greater than the width of the through hole 101 or the length of the first-level step at its bottom is greater than the length of the through hole 101. Preferably, an embedding groove 102 is provided on the circuit board, and the first-level step at the bottom of the socket 20 is embedded in the embedding groove 102. In this solution, the step at the bottom matches the shape of the embedding groove 102. This structure can increase stability. The setting of the embedding groove 102 can be realized by a double-layer circuit board, that is, through holes 101 with different sizes are opened on two layers of circuit boards. When the two layers of circuit boards are combined into a whole, an embedding groove 102 is formed at the through hole 101 with a smaller diameter.

[0036] Preferably, a plug hole is provided at the bottom of the socket 202 of the socket 20, and a plug connector is provided at the bottom of the terminal 30 to be inserted into the plug hole, and there is friction between the plug connector and the wall of the plug hole. The plug hole and the plug connector improve the stability of the structure through friction resistance, and are not used for conducting the circuit. This part is not shown in the figure.

[0037] Terminal :

[0038] like Figures 4 - 7 As shown, the side wall of the connecting terminal 30 is provided with abutting steps 302, and after the connecting terminal 30 is inserted, the abutting steps 302 abut against the top end of the socket 20. After insertion, the abutting steps 302 abut against the side wall of the jack 202 to avoid shaking.

[0039] Preferably, the connection terminal 30 is provided with a power line 40 and the inside thereof is provided with a connection between the power line 40 and the abutting boss 301 and the power line 40. The power line 40 is used to connect to a power source or other electrical components, such as LED lamps.

[0040] Circuit conduction part :

[0041] like Figures 4 - 7 As shown, there are two or three groups of abutting bosses 301 , U-shaped plates 201 , protrusions 1011 and power lines 40 . Whether there are two or three groups depends on the number of power lines 40 .

[0042] Preferably, each abutting boss 301 is arranged on different side walls of the through hole 101 , and the U-shaped plate 201 and the boss 1011 corresponding to the protrusion 1011 are respectively arranged on the side surfaces of the socket 20 and the terminal block 30 corresponding to the abutting boss 301 .

[0043] Preferably, smooth guide surfaces that abut against each other are provided between the raised portion 1011 and the contact, and between the contact and the top and bottom surfaces of the abutting boss 301. The side wall of the terminal block 30 is also provided with a circle of limiting bosses that match the socket 202. When the terminal block 30 is inserted or removed, the guide surface is used for guiding to avoid jamming. After the terminal block 30 is inserted, the limiting boss abuts against the side wall of the socket 202 to form a limit to avoid shaking.

[0044] It should be noted that there is a gap between the protrusion on the socket 20 and the side wall of the through hole 101 to provide a flipping space for the U-shaped plate 201 for disassembly; in addition, the abutment boss 301 on the terminal 30 can also be hollowed out and opened to form a structure with a certain elasticity similar to the U-shaped plate 201 to facilitate its disassembly, and this part can be directly used as a metal plate.

[0045] The above has introduced the title provided by the present utility model in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
