Technical Field

[0001] This utility model relates to the technical field, and in particular to a surge protector that integrates signal and power supply. Background Technology

[0002] A surge protector, also known as a lightning arrester, is an electronic device that provides safety protection for various electronic devices, instruments, and communication lines. When a surge current or voltage spike suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and divert the current in a very short time, thereby preventing damage to other equipment in the circuit.

[0003] Existing surge protectors that integrate signal and power supply have some shortcomings in terms of installation and fixing: on the one hand, the connection between the main body and the base is not stable enough and is prone to loosening or falling off when subjected to external forces, affecting the normal operation of the surge protector; on the other hand, the installation process is relatively cumbersome, requiring additional tools or complicated operating steps, which increases installation time and cost.

[0004] To address this issue, a surge protector integrating signal and power supply is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems of unstable connection between the main body and the base and complicated installation, this utility model provides a surge protector that integrates signal power supply.

[0006] This utility model is achieved using the following technical solution:

[0007] A surge protector integrating signal and power supply includes a base and a main body. The main body is snapped into the base. The back of the base is provided with a slot. The main body is provided with a fixing device, which includes a cavity, a lifting spring, a limiting cover, a slider, a sleeve rod, and a top rod.

[0008] The top rod is fixed to the upper surface of the slider, the sleeve rod is fixed to the lower surface of the slider, the lifting spring is installed in the cavity, the slider is installed in the cavity, and the sleeve rod passes through the lifting spring. The limiting cover is fixed to the top of the cavity, the top rod passes through the limiting cover, and the slider is located on the lower surface of the limiting cover.

[0009] The base has a connecting groove at the top and a through hole at the bottom that is compatible with the top rod.

[0010] Two clamping devices are symmetrically arranged in the slot. The clamping devices are located at the upper and lower ends of the slot. Each clamping device includes a snap-fit ​​groove, a limiting spring, and a clamping block. The clamping block is located in the snap-fit ​​groove. There are two limiting springs installed in the snap-fit ​​groove. One end of the limiting spring is fixed to the bottom of the snap-fit ​​groove, and the other end is fixedly connected to the clamping block.

[0011] An insulating plate is provided on the side wall of the main body, and the insulating plate is fixedly connected to the main body.

[0012] The base has a flame-retardant plate on its side wall, and four fixing posts are provided on the flame-retardant plate and fixed around the flame-retardant plate. The flame-retardant plate is fixedly connected to the base by the fixing posts.

[0013] The bottom of the main body is provided with a slide bar, which is inverted "T" shaped, and the base is provided with a matching slide groove, and the main body and the base are engaged and connected.

[0014] The present invention has the following advantages over the prior art:

[0015] 1. By setting a clamping device on the base and a fixing device on the main body, the connection between the main body and the base is made more stable through the double fixing of the fixing device and the clamping device. This can effectively prevent the main body from loosening or falling off when subjected to external force, and ensure the normal operation of the surge protector.

[0016] 2. No additional tools are needed during installation. Simply insert the main body into the base, and the installation can be completed using the automatic locking function of the fixing and clamping devices, which greatly shortens the installation time and reduces the installation cost.

[0024] like Figures 1 to 4 As shown, a surge protector integrating signal and power supply includes a base 1 and a main body 2. The main body 2 is snapped into the base 1. The back of the base 1 is provided with a slot 12. The main body 2 is provided with a fixing device, which includes a cavity 21, a lifting spring 22, a limiting cover 23, a slider 25, a sleeve rod 26 and a top rod 24.

[0025] The top rod 24 is fixed to the upper surface of the slider 25, the sleeve rod 26 is fixed to the lower surface of the slider 25, the lifting spring 22 is installed in the cavity 21, the slider 25 is installed in the cavity 21, and the sleeve rod 26 passes through the lifting spring 22. The limiting cover 23 is fixed to the top of the cavity 21, the top rod 24 passes through the limiting cover 23, and the slider 25 is located on the lower surface of the limiting cover 23.

[0026] The base 1 has a connecting groove 11 at its top, and a through hole at the bottom of the connecting groove 11 that matches the push rod 24. When the main body 2 is inserted into the base 1, the push rod 24 is compressed, causing the slider 25 to move downwards, and the sleeve 26 compresses the lifting spring 22 downwards. After the main body 2 is installed in place, the push rod 24 pops upwards under the action of the lifting spring 22 and locks into the through hole at the bottom of the connecting groove 11 at the top of the base 1, thus achieving initial fixation between the main body 2 and the base 1.

[0027] Two clamping devices are symmetrically arranged within the slot 12, located at the upper and lower ends of the slot 12. Each clamping device includes a snap-fit ​​groove, a limiting spring 14, and a locking block 13. The locking block 13 is disposed within the snap-fit ​​groove. Two limiting springs 14 are provided and installed within the snap-fit ​​groove. One end of each limiting spring 14 is fixed to the bottom of the snap-fit ​​groove, and the other end is fixedly connected to the locking block 13. When the base 1 is installed on an external device, the externally provided fixed track is inserted into the slot 12, causing the locking block 13 to be compressed and retract into the snap-fit ​​groove, simultaneously compressing the limiting spring 14. When the main body 2 is installed in place, the locking block 13 pops out under the action of the limiting spring 14, locking the main body 2 and further enhancing the connection stability between the main body 2 and the base 1.

[0028] An insulating plate 3 is provided on the side wall of the main body 2, and the insulating plate 3 is fixedly connected to the main body 2. The insulating plate 3 can effectively prevent current leakage, improve the insulation performance of the surge protector, and ensure safe use.

[0029] A flame-retardant plate 4 is provided on the side wall of the base 1. Four fixing posts 41 are provided on the flame-retardant plate 4 and fixed around its perimeter. The flame-retardant plate 4 is fixedly connected to the base 1 by the fixing posts 41. The flame-retardant plate 4 can prevent the spread of fire in the event of a fire, thus improving the flame-retardant performance of the surge protector.

[0030] The bottom of the main body 2 is provided with a sliding strip, which is inverted "T" shaped. The base 1 is provided with a matching sliding groove 15, and the main body 2 and the base 1 are engaged and connected. The cooperation between the sliding strip and the sliding groove 15 can make the installation of the main body 2 smoother, and also play a certain role in positioning and fixing.

[0031] The working principle of this utility model is as follows: When in use, align the four fixing posts 41 on the flame retardant plate 4 with the corresponding slots 12 on the side wall of the base 1, and gently press the flame retardant plate 4 so that the fixing posts 41 are inserted into the slots 12, thus completing the snap-fit ​​and fixed connection between the flame retardant plate 4 and the base 1.

[0032] Align the slider at the bottom of the main body 2 with the groove 15 on the base 1, and slowly insert the main body 2 into the base 1. During the insertion process, the push rod 24 is squeezed and moves downward, causing the slider 25 to compress the lifting spring 22. At the same time, the locking block 13 is squeezed and retracts into the locking groove, compressing the limiting spring 14. When the main body 2 is installed in place, the push rod 24 pops up under the action of the lifting spring 22 and locks into the through hole at the bottom of the top connecting groove 11 of the base 1. The locking block 13 pops up under the action of the limiting spring 14, locking the main body 2 and achieving a stable connection between the main body 2 and the base 1.

[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
