Description
Technical Field
[0001] This utility model relates to the field of surge protector technology, and in particular to a surge protector with a wiring reinforcement structure. Background Technology
[0002] A surge protector, also known as a lightning protection device, is an indispensable device for lightning protection of electronic equipment. Its function is to divert current within a very short time, thereby preventing damage to other equipment in the circuit. When installing and using a surge protector, external cables need to be connected to its wiring terminals to form a complete protection circuit.
[0003] Currently, the conventional wiring method involves directly tightening the cable with bolts inside the wiring holes, which achieves basic electrical continuity. However, the operating environment of surge protectors is often not ideal. For example, in industrial control cabinets and distribution boxes, mechanical vibrations generated during equipment operation or thermal expansion and contraction caused by temperature changes can cause the bolts tightening the cable to gradually loosen over time.
[0004] If bolted connections become loose, it will not only increase contact resistance, causing abnormal heating at the terminals and potentially even leading to a fire, but it will also affect the surge discharge performance of the surge protector itself, rendering it unable to provide effective protection at critical moments and posing a significant safety hazard to downstream equipment. The existing structure relies solely on bolts to perform both electrical connection and mechanical fixation functions, lacking auxiliary reinforcement for cables, resulting in insufficient long-term reliability of the connection.
[0005] Therefore, this utility model proposes a surge protector with a wiring reinforcement structure to overcome the shortcomings of the prior art. Utility Model Content
[0006] In view of the problem that existing surge protectors rely solely on bolts for electrical connection and mechanical fixation, lacking auxiliary reinforcement of cables, resulting in insufficient long-term reliability of the connection, this utility model aims to provide a surge protector with a wiring reinforcement structure that has been improved and can effectively solve the above problems.
[0007] This utility model provides a surge protector with a wiring reinforcement structure, including: a body, a wiring hole opened on the body, and a bolt threaded into the wiring hole; and a reinforcement mechanism fixedly connected to the body and located above the wiring hole.
[0008] The reinforcement mechanism includes an outer ring for cable passage, a locking head fixed to the top of the outer ring and slidably connected to the device body, a limiting block one fixed to the device body and located on one side of the locking head, and a control component including a limiting block two.
[0009] Furthermore, the second limiting block of the control component is movably connected to the body and located on the other side of the card head. The first limiting block and the second limiting block are used to engage with the two sides of the card head respectively to achieve locking when the card head is pressed to a predetermined position.
[0010] Preferably, the control component further includes a pull rod, which is tractively connected to the second limiting block. The pull rod is adapted to be pulled to move the second limiting block, thereby disengaging from the locking block head.
[0011] Preferably, the card head is provided with a first slot and a second slot, the first limiting block is provided with a protrusion adapted to the first slot, and the second limiting block is adapted to be inserted into the second slot.
[0012] Preferably, the surge protector with wiring reinforcement structure further includes a splicing mechanism disposed on the side wall of the device body, the splicing mechanism being used to connect to another device body.
[0013] Preferably, the splicing mechanism includes a rotating rod and a clamp, the rotating rod being horizontally fixed to the side wall of the device body, and the clamp being rotatably connected around the rotating rod.
[0014] Preferably, the splicing mechanism further includes an external limiting rod, which is fixed to the body and adjacent to the caliper to limit the rotation range of the caliper.
[0015] Preferably, a triangular block that cooperates with the caliper is fixed on the side wall of another of the said devices.
[0016] Preferably, the triangular block has a wedge-shaped guide surface, and the caliper is spread open along the wedge-shaped guide surface when the two bodies are close together, and springs back to engage after passing the triangular block.
[0017] This utility model has the following beneficial effects:
[0018] 1. This utility model, by setting up a reinforcement mechanism, on the basis of using bolts to lock the cable, presses the outer ring to drive the locking block head, so that the first limiting block and the second limiting block engage and lock the locking block head, and the outer ring presses the cable, which solves the problem that the cable is easily loosened and has poor contact due to vibration or external pulling when it is only fixed by bolts in the prior art. It achieves the technical effect of double fixing of the cable and improving the reliability and safety of the connection.
[0019] 2. This utility model solves the problems of cumbersome operation and unstable connection when multiple protectors are installed side by side in the prior art by setting a splicing mechanism on the side wall of the device body. The clamp on one device body and the triangular block on another device body automatically open and engage when they are close to each other. This achieves the technical effect of quick splicing, convenient installation and stable overall structure after splicing.
[0020] 3. This utility model solves the problem of difficulty in unlocking and maintenance after the reinforcement structure is locked by setting a control component including a pull rod in the reinforcement mechanism. The pull rod is linked with the second limiting block, which achieves the technical effect of quickly unlocking by pulling the pull rod to easily disengage the second limiting block. The operation is simple and intuitive, improving ease of use. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0032] Example:
[0033] Please refer to Figures 1 to 4 This utility model provides a surge protector with a wiring reinforcement structure, which aims to solve the problems of insufficient wiring connection reliability and complex splicing structure of multiple device bodies in the prior art.
[0034] like Figure 1 and Figure 2 As shown, the surge protector with wiring reinforcement structure includes a basic body 1, on which a wiring hole 2 is provided. A bolt 5 for locking the cable is threaded into the wiring hole 2. The initial electrical fixation of the cable inserted into the wiring hole 2 is achieved by tightening the bolt 5.
[0035] On the device body 1, and above the wiring hole 2, a reinforcement mechanism 3 for secondary physical reinforcement of the cable is fixedly connected; the reinforcement mechanism 3 is an integral structure, and its core components include an outer ring 31, a locking head 32, a limiting block 33, and a control component 34.
[0036] The outer ring 31 serves as the cable inlet and clamping element, and is fixed to the top of the locking head 32, forming a linked pressing part with the locking head 32; the locking head 32 serves as the main body for locking, and is slidably connected to the device 1, so that it can move towards the cable under external pressure.
[0037] To lock the card block head 32, a limit block 33 is provided on one side of the card block head 32, and the limit block 33 is fixedly connected to the body 1; a control component 34 is provided on the other side of the card block head 32, and the control component 34 includes a limit block 341 movably connected to the body 1.
[0038] The setting of limit block 1 33 and limit block 2 341 forms a double-sided limiting structure for the card head 32. When the outer ring 31 is pressed and the card head 32 is slid down to the predetermined position, the limit block 1 33 and limit block 2 341 respectively engage with the card head 32 from both sides, thereby firmly locking the card head 32, and then pressing the cable through the outer ring 31.
[0039] Reference Figure 1 and Figure 2The control component 34 specifically includes a pull rod 342, which is connected to the second limiting block 341. When it is necessary to unlock the reinforcement mechanism 3, by pulling the pull rod 342, the pull rod 342 will drive the second limiting block 341 to bend or move outward, so that the second limiting block 341 is disengaged from the locking state with the locking head 32. At this time, the locking head 32 will reset upward under the action of the reset spring, thereby releasing the outer ring 31 from pressing the cable. The locking head 32 is correspondingly provided with a first The device has a slot and a second slot; the first limiting block 33 is a component fixed on the body 1, and it has a protrusion that matches the first slot; while the second limiting block 341, which is a movable component, is adapted to be inserted into the second slot. The protrusion of the first limiting block 33 automatically engages in the first slot, and the second limiting block 341 also automatically engages in the second slot. This double-sided slot limiting block engaging structure ensures high reliability and stability of locking the locking block head 32 and prevents it from accidentally loosening under vibration.
[0040] As a preferred embodiment, refer to Figure 3 and Figure 4 The splicing mechanism 4 specifically includes a rotating rod 41 and a clamp 42. The rotating rod 41 is horizontally fixed to the side wall of the device 1. The clamp 42 is rotatably connected to the device 1 through the rotating rod 41, so that it can be stored or unfolded. The splicing mechanism 4 also includes an external limiting rod 44, which is fixed to the device 1 and adjacent to the clamp 42, and is used to physically limit the rotation range of the clamp 42. A triangular block 43 is fixed on the corresponding side wall of the other device 1. The triangular block 43 is used to structurally cooperate with the clamp 42. Furthermore, the triangular block 43 has a wedge-shaped guide surface, and its structural shape is adapted to guide the clamp 42 when the two devices 1 are close to each other.
[0041] The implementation principle of this application embodiment is as follows: The surge protector body 1 has multiple wiring holes 2. By connecting an external cable, the bolt 5 is rotated to lock the cable inserted into the corresponding wiring hole 2. In order to reinforce the cable, the wiring is reinforced by a reinforcement mechanism 3. The reinforcement mechanism 3 is installed above the wiring hole 2. The connected cable is inserted into the wiring hole 2 from the inside of the outer ring 31. Pressing the outer ring 31 drives the locking head 32, so that the protrusion of the first limiting block 33 is locked in the slot of the locking head 32. On the other side of the locking head 32, there is another second limiting block 341 that is also locked. Continue to press to make the locking position deeper, so that the cable is reinforced more tightly. Pulling the pull rod 342 can drive the second limiting block 341 to bend outward, which can release the locking head 32. The unlocking and reinforcement control is realized by using the control component 34.
[0042] In electrical applications, it is often necessary to connect multiple devices 1 together. In order to make the connection of devices 1 tighter, the clamp 42 can rotate around the rotating rod 41. When not connected, it can be stored. When splicing, the clamp 42 first contacts the triangular block 43. After contact, the clamp 42 continuously opens to both sides until the two devices 1 are connected. The clamp 42 is prevented from disengaging due to the limit of the external limiting rod 44. Finally, the splicing mechanism 4 is used to achieve the splicing between devices 1.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
