[0002] A surge protector is an electronic device that provides safety protection for various electronic devices, instruments, and communication lines. Installing a surge protector can suppress surges and instantaneous overvoltages on the line and discharge the overcurrent on the line. A surge protector consists of an external housing and components arranged inside the housing. Currently, the existing surge protector housing usually has a built-in clamping structure, usually a clamping groove opened on the housing body and a clamping block fitted in the clamping groove. By operating the clamping block, the surge protector housing can be installed on the guide rail inside the distribution box;

[0003] Due to the compact internal space of the power distribution cabinet, surge protectors are often installed among numerous electrical components, and dense lines and other devices are arranged above and below them. This layout makes it difficult for operators to directly reach the clamping block at the end of the housing when maintenance or replacement of the surge protector is required. Since there are wires connected to both the upper and lower ends of the surge protector, when the wires at the bottom of the surge protector block the clamping block, it is difficult for the staff to observe the position of the clamping block, increasing the operation difficulty. Therefore, a surge protector housing is proposed for the above situation. Content of the Utility Model

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The following will further describe this application in detail with reference to Figure 1 —4.

[0025] The embodiments of this application disclose a surge protector housing. Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a surge protector housing includes a surge protector housing 1. There is a clamping block 2 on the surge protector housing 1. The clamping block 2 is made of elastic plastic. A connecting mechanism 3 is fixedly connected to the clamping block 2. The connecting mechanism 3 is made of plastic material. The connecting mechanism 3 includes an L-shaped rod 4 and a limiting rod 10. There are two L-shaped rods 4. One ends of the two L-shaped rods 4 are respectively fixed on one side of the outer wall of the clamping block 2. A first connecting plate 5 and a second connecting plate 6 are respectively fixedly connected to the two L-shaped rods 4. An opening 7 is formed between the first connecting plate 5, the second connecting plate 6 and the two L-shaped rods 4. At the end of the top of the second connecting plate 6 far from the clamping block 2, two upright rods 12 are fixedly connected. At the bottom of the second connecting plate 6, two convex blocks 8 are fixedly connected. One of the convex blocks 8 is close to the end of the L-shaped rod 4, and the other convex block 8 is located at the middle part of the L-shaped rod 4. When operating the convex block 8, the force is more evenly distributed, which is convenient for making the L-shaped rod 4 descend.

[0026] There are two limiting rods 10, and both of the two limiting rods 10 are fixedly connected to the surge protector housing 1. There are sliding grooves 11 on both of the two limiting rods 10, and the sliding grooves 11 are in sliding fit with the vertical rods 12. Both of the two limiting rods 10 are rectangular rod structures and are fixed to the surge protector housing 1 by bolts.

[0027] Referring to Figure 1 and Figure 2 , there are wiring ports 101 opened on the surge protector housing 1. The number of the wiring ports 101 is two, and the two wiring ports 101 are respectively located at the top and the bottom of the surge protector housing 1.

[0028] By providing the wiring ports 101, it is used for the assembly of the wire harness and electrically connecting the surge protector with other components through the wire harness.

[0029] Referring to Figure 1 , Figure 2 and Figure 3 , there is an assembly groove 102 opened on the surge protector housing 1. There is an installation groove 103 opened on the surge protector housing 1 near the assembly groove 102, and a clamping block 2 is in sliding fit in the installation groove 103.

[0030] By providing the assembly groove 102, it is used to cooperate with the guide rail in the power distribution cabinet to complete the installation of the surge protector housing 1. The installation groove 103 is adapted to the clamping block 2, and this is a common structure on the surge protector housing 1 in the market, so there is no need to elaborate here.

[0031] Referring to Figure 1 , Figure 2 and Figure 3 , the wiring port 101 located at the bottom of the surge protector housing 1 is communicated with the opening 7, and the size of the opening 7 is larger than that of the wiring port 101.

[0032] Through the design of the opening 7, it ensures normal wiring processing, and the size of the opening 7 is larger than that of the wiring port 101, which further ensures the convenience of wiring and will not interfere with normal wiring.

[0033] Referring to Figure 1 , Figure 2 and Figure 3 , the tops of the first connecting plate 5 and the second connecting plate 6 and the tops of the two L-shaped rods 4 are all in contact with the outer wall of the surge protector housing 1.

[0034] Furthermore, the first connecting plate 5, the second connecting plate 6 and the L-shaped rod 4 are all in contact and fit with the outer wall of the surge protector housing 1. At this time, the clamping block 2 is in a working state and abuts against the guide rail in the power distribution cabinet, and the surge protector housing 1 is in a fixed installation state.

[0035] Referring to Figure 3, the shapes of both convex blocks 8 are rectangular, rectangular grooves are provided on both convex blocks 8, a connecting rod 9 is fixedly connected to both convex blocks 8, the connecting rod 9 is a semi-circular rod structure, and the outer wall of the connecting rod 9 has anti-slip lines.

[0036] Through the design of the rectangular groove, during operation, the end of a screwdriver can be inserted into the rectangular groove and pressed downward to complete the downward movement of the L-shaped rod 4, thereby driving the clamping block 2 to move downward to complete unlocking. The connecting rod 9 is provided for the staff to hold with their fingers and pull the L-shaped rod 4 downward with their fingers.

[0037] Working principle: When disassembling the surge protector housing 1 installed in the power distribution cabinet, the convex block 8 can be pulled downward so that the convex block 8 drives the two L-shaped rods 4 to descend. The descent of the two L-shaped rods 4 causes the vertical rod 12 to slide and descend in the sliding groove 11. At the same time, the descent of the L-shaped rod 4 drives the clamping block 2 to descend, and the end of the clamping block 2 slides from the assembly groove 102 into the installation groove 103. The assembly groove 102 no longer abuts against the guide rail in the power distribution cabinet, completing unlocking, and the surge protector housing 1 can be removed from the guide rail.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
