[0021] See also Figure 1 and Figure 3 , an embodiment of the utility model provides a surge protector 999 with a snap mechanism. The surge protector 999 includes a surge protector module box 200 and a surge protector base 400. The surge protector module box 200 can be plugged into the surge protector base 400. The surge protector 999 can discharge current to the ground when there is a lightning strike or system overvoltage to protect the electrical appliances in the circuit. In this embodiment, the surge protector base 400 can accommodate four surge protector module boxes 200 to be plugged in together to form a 4P surge protector. See Figure 4In other embodiments, the surge protector base 400 can also be plugged into only one surge protector module box 200 to form a 1P surge protector. In more embodiments, the surge protector base 400 can also be plugged into two, three or other number of surge protector module boxes 200.

[0022] The surge protector module box 200 includes a pressurized movable part 210, a first limit strip 220, a second limit strip 230, a third limit strip 240, a fourth limit strip 250, a first electrical connector 260, a second electrical connector 270 and a chute 280. The pressurized movable part 210, the first limit strip 220, the second limit strip 230 and the chute 280 are arranged on the first side 201 of the surge protector module box 200. The first limit strip 220, the second limit strip 230 and the chute 280 are arranged below the pressurized movable part 210. The chute 280 is located between the first limit strip 220 and the second limit strip 230. The third limit strip 240 and the fourth limit strip 250 are arranged on the second side 202 of the surge protector module box 200. The first electrical connector 260 and the second electrical connector 270 are arranged below the surge protector module box 200.

[0023] The pressurized movable part 210 includes a connecting end 211, a movable end 212, a buckle hole 213, two convex strips 214 and a continuous concave-convex anti-skid pattern 215. The connecting end 211 is integrally connected to the surge protector module box 200. The movable end 212 extends from the connecting end 211 toward the surge protector base 400. The movable end 212 is movable when pressurized. The buckle hole 213 is arranged on the movable end 212. The buckle hole 213 is a groove structure that is arranged on the outer surface of the movable end 212 and is concave inward. Two convex strips 214 are arranged at the end 2121 of the movable end 212. The ends of the two convex strips 214 and the end 2121 of the movable end 212 are arc-shaped structures. The two convex strips 214 are respectively arranged on both sides of the buckle hole 213. The continuous concave-convex anti-skid pattern 215 is arranged on the outer side of the pressurized movable part 210. The second side edge 202 of the surge protector module box 200 and the position corresponding to the pressure-bearing movable part 210 are also provided with continuous concave-convex anti-skid patterns. The anti-skid patterns can provide an anti-skid effect when the user disassembles and takes out the surge protector module box 200. The two convex strips 214 and the convex heights of the first limiting strip 220 and the second limiting strip 230 are on the same plane.

[0024] The surge protector base 400 is roughly U-shaped, and the surge protector module box 200 can be inserted into the U-shaped opening. The surge protector base 400 includes a buckle 410, a first guide slot 420, a second guide slot 430, a third guide slot 440, a fourth guide slot 450, a first electrical connection jack 460, and a second electrical connection jack 470. The buckle 410, the first guide slot 420, and the second guide slot 430 are arranged on the first inner side wall 401 of the surge protector base 400. The buckle 410 is located between the first guide slot 420 and the second guide slot 430. The buckle 410 is a convex block structure arranged on the first inner side wall 401. The third guide slot 440 and the fourth guide slot 450 are arranged on the second inner side wall 402 of the surge protector base 400. The first electrical connection jack 460 and the second electrical connection jack 470 are disposed on the bottom inner side 403 of the surge protector base 400. The first limiting strip 220 and the second limiting strip 230 can be slidably inserted into the first guide slot 420 and the second guide slot 430, respectively. The third limiting strip 240 and the fourth limiting strip 250 can be slidably inserted into the third guide slot 440 and the fourth guide slot 450, respectively. The two convex strips 214 can be slidably inserted into the first guide slot 420 and the second guide slot 430, respectively. The first guide slot 420, the second guide slot 430, the third guide slot 440 and the fourth guide slot 450 provide installation guides for the surge protector module box 200 to be inserted into the surge protector base 400. The protrusion heights of the two protrusions 214 and the first limiting strip 220 and the second limiting strip 230 are on the same plane, so that the surge protector module box 200 and the surge protector base 400 fit tightly and the combination is more stable.

[0025] When the surge protector module box 200 needs to be connected to the surge protector base 400, the first limit strip 220 and the second limit strip 230 are respectively slid and inserted into the first guide slot 420 and the second guide slot 430, and the third limit strip 240 and the fourth limit strip 250 are respectively slid and inserted into the third guide slot 440 and the fourth guide slot 450. In this process, the buckle 410 makes way through the make-way slot 280, so that the four limit strips slide smoothly into the four guide slots respectively, until the buckle 410 contacts the pressed active part 210, and the buckle 410 contacts the pressed active part first. The arcuate end 2121 of the movable end 212 of the movable part 210 is pressed, and the buckle 410 slides to the outer side of the movable end 212 through the arcuate end 2121, pressing the movable end 212, and the movable end 212 is pressed and deflected inward until the buckle 410 is buckled in the buckle hole 213, and the movable end 212 is reset. At the same time, the two convex strips 214 are respectively slid and snapped into the first guide slot 420 and the second guide slot 430, and the first electrical connector 260 is plugged into the first electrical connection socket 460, and the second electrical connector 270 is plugged into the second electrical connection socket 470, and the installation is completed. The buckle 410 is buckled with the buckle hole 213, and the installation is stable. In addition, the four limit strips are respectively slid and snapped into the four guide slots, and the installation is smooth while further improving the installation stability. The first electrical connector and the second electrical connector are plugged into the first electrical connection socket and the second electrical connection socket, and the installation stability is further improved.

[0026] When it is necessary to remove the degraded or failed film protector module box 200 from the surge protector base 400, the compressed movable part 210 is pressed, the movable end 212 is compressed and deflected inward, the buckle 410 is disengaged from the buckle hole 213, and a pulling force is applied to pull the first electrical connector 260 and the second electrical connector 270 out of the first electrical connection jack 460 and the second electrical connection jack 470 respectively, and the four limit bars slide from the four guide slots in the direction opposite to the installation direction respectively until the surge protector module box 200 is completely separated from the surge protector base 400. By pressing the compressed movable part 210, the buckle 410 can be separated from the buckle hole 213, and the disassembly is efficient and convenient.

[0027] The utility model provides a surge protector base with a buckle mechanism. A buckle is arranged on the surge protector base, a pressure-bearing active part is arranged on the surge protector module box, and a buckle hole is arranged on the pressure-bearing active part. The buckle is buckled with the buckle hole to ensure stable installation. The pressure-bearing active part is pressed to separate the buckle from the buckle hole, so that disassembly is convenient.
