Description

Technical Field

[0001] This utility model relates to the field of surge protector technology, specifically a combined semiconductor surge protector. Background Technology

[0002] A semiconductor surge protector is an electronic device used to limit transient overvoltages and guide the discharge of surge currents. It is primarily used to protect electrical or electronic systems with low withstand voltage levels from damage caused by lightning strikes, lightning electromagnetic pulses, or operational overvoltages. The main component of a semiconductor surge protector is an MOV, or metal oxide varistor. An MOV consists of three parts: a central metal oxide material, and two semiconductors on either side connecting the power supply and ground.

[0003] The existing technology has the following shortcomings: In the existing technology, the "Combined Surge Protector" with application number 202321891141.8 "includes a protector body, two wiring terminals are installed at each of the upper and lower ends of the protector body, an indicator window is installed on one side of the protector body, an installation groove A is opened inside the protector body, an installation groove B is opened at the edge of the installation groove A, a side cover is provided inside the installation groove B, and the side cover is fixedly connected to the protector body by screws, a metal contact A is embedded inside the installation groove A, and a metal contact B is embedded at the edge of the installation groove B".

[0004] The surge protectors described above are equipped with surge protection elements and side covers, and each surge protection element is of a different type, which can be used to deal with different types of surges. The terminals of the surge protectors are usually exposed. When the terminals are not used for a long time, dust can easily enter the surge protector through the opening of the terminals, which can affect the service life of the surge protector over time. In addition, the terminals of the surge protector and the wire connectors of the protected equipment are usually simply plugged in and fixed. The connection between the wire connectors of the protected equipment and the terminals of the surge protector can easily become loose, which can lead to poor contact between the wire connectors of the protected equipment and the terminals of the surge protector. Utility Model Content

[0005] The purpose of this invention is to provide a combined semiconductor surge protector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined semiconductor surge protector, comprising a protector body, an indicator window on one side of the protector body, a mounting groove on one side of the protector body, four sets of surge protection elements disposed in the mounting groove, a side cover on the top of the mounting groove, a wiring terminal on the top of the protector body, a wire connector on the wiring terminal, a sealing component and a mounting rod on the top of the protector body, a positioning block on the mounting rod, an anti-slip pad on the top of the wire connector, and a connection hole on the top of the protector body, wherein a fastener is disposed in the connection hole;

[0007] The sealing assembly includes a fixing block, a sealing block, a magnetic sheet, a sealing gasket, and a fixing rod. The fixing block is provided on the top of the protector body, the sealing block is provided on the fixing block, the magnetic sheet is provided on one side of the sealing block, the sealing gasket is provided on the sealing block, and the fixing rod is provided on the top of the sealing block.

[0008] As a preferred embodiment of this utility model, one end of the wire connector is inserted into the terminal block, and the fixing block is fixedly installed on the protector body on one side of the terminal block.

[0009] As a preferred technical solution of this utility model, the sealing block and the fixing block are connected by a hinge. When the sealing block is flipped to the top of the terminal block, a sealing gasket is fixedly installed on the bottom and one side of the sealing block, and the specific material of the sealing gasket is soft rubber.

[0010] As a preferred technical solution of this utility model, when the sealing block is flipped to the top of the terminal block, a fixing rod is fixedly installed on the top of the sealing block, the connecting hole is adapted to the fixing rod, there is an insertion between the fixing rod and the connecting hole, and the fixing rod is made of soft plastic, while the fastener is made of soft silicone.

[0011] As a preferred embodiment of this utility model, sealing blocks are provided on both sides of the terminal block, and magnetic pieces are embedded on the corresponding sides of the two sets of sealing blocks, with the two sets of magnetic pieces attracting each other magnetically.

[0012] As a preferred embodiment of this utility model, the mounting rod is fixedly mounted on the protector body on one side of the terminal block, one end of the positioning block is rotatably mounted on one end of the mounting rod, and the bottom end of the positioning block is in contact with the top of the wire connector.

[0013] As a preferred technical solution of this utility model, anti-slip pads are fixedly installed at both ends of the top of the wire connector. The top of the anti-slip pad is designed with several sets of anti-slip particles, and the specific material of the anti-slip pad is soft silicone. Mounting rods are provided on both sides of the wire connector. There are four sets of terminals, and the four sets of terminals have the same installation structure.

[0014] Compared with the prior art, this utility model provides a combined semiconductor surge protector, which has the following advantages:

[0015] 1. This combined semiconductor surge protector, by setting a sealing component, connecting holes, and fasteners, allows the two sets of sealing blocks corresponding to the terminals to be used to be flipped to both sides of the terminals, and the corresponding fixing rods to be snapped into the connecting holes to fix the sealing blocks. At this time, the sealing blocks will not affect the normal use of the terminals. When the two sets of sealing blocks corresponding to the unused terminals are flipped to the top of the terminals, the sealing blocks will not flip arbitrarily due to the magnetic attraction between the magnetic pieces of the two sets of sealing blocks. At this time, the sealing blocks can achieve a sealing and dustproof effect on the opening of the unused terminals. This structure can achieve a sealing and dustproof effect on the opening of the unused terminals without affecting the normal use of the terminals to be used.

[0016] 2. This combined semiconductor surge protector, by setting up an installation rod, positioning blocks, and anti-slip pads, allows two sets of positioning blocks corresponding to the terminals to be used to be flipped to both sides of the terminals. One end of the wire connector is then inserted into the terminal to be used. Flipping the two sets of positioning blocks ensures that one end of each set is placed on the wire connector. The anti-slip pads improve the anti-slip properties of the wire connector parts in contact with the positioning blocks, preventing the positioning blocks from detaching from the wire connectors. At this time, the positioning blocks can limit the wire connectors, making it less likely for the connection between the wire connectors of the protected equipment and the terminals of the surge protector to become loose.

[0025] In this embodiment, one end of the wire connector 7 is inserted into the terminal block 6, and the fixing block 801 is fixedly installed on the protector body 1 on one side of the terminal block 6.

[0026] Specifically, the fixing block 801 facilitates the installation of the sealing block 802;

[0027] In this embodiment, the sealing block 802 and the fixing block 801 are connected by a hinge. When the sealing block 802 is flipped to the top of the terminal 6, the bottom and one side of the sealing block 802 are fixedly installed with a sealing gasket 804, and the specific material of the sealing gasket 804 is soft rubber.

[0028] Specifically, when the sealing block 802 is flipped to the top of the terminal 6, it can seal and prevent dust from entering the terminal 6.

[0029] In this embodiment, when the sealing block 802 is flipped to the top of the terminal 6, a fixing rod 805 is fixedly installed on the top of the sealing block 802. The connecting hole 12 is adapted to the fixing rod 805. There is an insertion between the fixing rod 805 and the connecting hole 12.

[0037] The working principle and usage process of this utility model are as follows: By pulling the corresponding fixing rod 805, the two sets of sealing blocks 802 corresponding to the terminal 6 to be used are flipped to the two sides of the terminal 6 respectively. At the same time, the corresponding fixing rod 805 is snapped into the connection hole 12. After the fastener 13 is squeezed and deformed, it will stick tightly to the fixing rod 805.

At this time, the sealing block 802 will not affect the normal use of the terminal 6. The two sets of sealing blocks 802 corresponding to the unused terminal 6 are flipped to the top of the terminal 6. Since the magnetic force between the magnets 803 on the corresponding sides of the two sets of sealing blocks 802 is attracted, the sealing block 802 will not arbitrarily flip. At this time, the sealing block 802 can seal the opening of the unused terminal 6 and prevent dust.

The anti-slip pad 11 can improve the anti-slip performance of the part of the wire connector 7 that the positioning block 10 contacts. The positioning block 10 will not detach from the wire connector 7 at will. At this time, the positioning block 10 can limit the wire connector 7. The connection between the wire connector 7 of the device to be protected and the terminal 6 of the surge protector is not easy to loosen. Moreover, each set of surge protection elements 4 of the surge protector is of a different type and can be used to deal with different types of surges. The various sets of surge protection elements 4 can be combined to form a more comprehensive surge protector.
