[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-3 As shown, a crack-resistant splicing electronic circuit board includes an electronic circuit board 1, and a splicing component 3 is provided on the outer wall of the electronic circuit board 1.

[0024] The splicing component 3 includes a semi-circular protrusion 301 located in the middle of one side of the outer wall of the electronic circuit board 1. Circular holes 302 are respectively opened on both sides of the semi-circular protrusion 301. A semi-circular slot 303 is opened in the middle of the side of the outer wall of the electronic circuit board 1 that forms a right angle with the semi-circular protrusion 301. Springs 306 are respectively provided on both sides of the inner wall of the semi-circular slot 303. A retaining ball 307 is provided at one end of the spring 306. A protective retaining sleeve 304 is wrapped around the outer wall of the electronic circuit board 1. Rubber retaining strips 305 are respectively provided at the upper and lower ends of one side of the outer wall of the protective retaining sleeve 304.

[0025] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, a component 2 is provided on the upper side of the electronic circuit board 1. The component 2 is electrically connected to the electronic circuit board 1. The electronic circuit board 1 is divided into four groups. There are four groups of semi-circular protrusions 301, four groups of semi-circular slots 303, eight groups of springs 306, eight groups of ball catches 307, and eight groups of round holes 302. The semi-circular protrusions 301 are fixedly connected to the electronic circuit board 1. The springs 306 are fixedly connected to the semi-circular slots 303. The ball catches 307 are fixedly connected to the springs 306. The semi-circular protrusions 301 and the semi-circular slots 303 are engaged. The ball catches 307 and the round holes 302 are engaged. The protective sleeve 304 is fixedly connected to the rubber strap 305. The protective sleeve 304 is engaged with the electronic circuit board 1.

[0026] Among them, the rubber clip 305 serves as an anti-slip and protective measure. The electronic circuit board 1 is divided into four parts, and the semi-circular protrusions 301 and semi-circular slots 303 are arranged in a certain pattern. They need to be spliced ​​in the correct installation order and can be marked to prevent loss or incorrect splicing. The protective clip sleeve 304 serves to protect the spliced ​​electronic circuit board 1.

[0027] The working process of this utility model is as follows: When using the crack-resistant splicing electronic circuit board designed in this scheme, if it is necessary to splice the electronic circuit board 1, the semi-circular protrusion 301 on the outer wall of one piece of the circuit board 1 is aligned with the semi-circular groove 303 of another piece of the circuit board to make them snap together. During the snapping process, the spring 306 and the retaining ball 307 are compressed. When the retaining ball 307 encounters the round hole 302, the rebound force of the spring 306 will snap it into the round hole 302, so that the semi-circular protrusion 301 and the semi-circular groove 303 are snapped and aligned. The other pieces are then spliced ​​together in sequence. The circuit boards, which are divided into blocks, are spliced ​​together using the same method. After splicing, the protective card sleeve 304 is attached to the outer wall of the electronic circuit board 1 to protect the electronic circuit board 1. The protective card sleeve 304 has heat dissipation holes, which will not affect the use of the electronic circuit board 1. The rubber clip 305 prevents wear and tear and is easy to disassemble. By removing the protective card sleeve 304, the electronic circuit board 1 is pulled in turn to separate the semi-circular slot 303 from the semi-circular protrusion 301, thus facilitating the transportation of the electronic circuit board 1.
