Description

Technical Field

[0001] This utility model relates to the field of door and window wire protection technology, and more specifically, it relates to a contact wire protector. Background Technology

[0002] Traditional line protection devices often use iron or alloy contacts and contact holders, which are prone to rust and corrosion when exposed to humid or highly oxidizing environments for extended periods. This leads to increased contact resistance, decreased conductivity, and even the risk of overheating or short circuits. Furthermore, existing protectors have limited contact height adjustment ranges, making it difficult to adapt to different wire diameters or installation scenarios. The small contact holders are also susceptible to misalignment during installation, causing poor contact or failure to conduct electricity, thus affecting equipment reliability. Therefore, there is an urgent need for a line protection device with high corrosion resistance, flexible adaptability, and anti-misalignment design to solve these technical problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wire protection device with high corrosion resistance, flexible adaptability and adjustable contact head height.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a contact over-line protector, characterized in that: it includes a contact box and a contact plate box, the contact box having an open sliding cavity, a contact seat slidably fitted inside the sliding cavity, one end of the contact seat having multiple contact heads extending from the opening of the sliding cavity, and the other end having a wiring terminal, the wiring terminal penetrating the bottom wall of the sliding cavity and extending out of the contact box, the contact seat also having an adjustment structure for adjusting the height of the contact heads extending out of the contact box, the contact plate box having the same number of contact plate seats as the contact heads, and both the contact heads and the contact plate seats being made of copper.

[0005] The present invention is further configured such that: the adjustment structure includes an extension adjustment bolt and a shortening adjustment bolt, the extension adjustment bolt is inserted from the tail end of the contact box into the sliding cavity and extends into the contact seat, the contact seat is provided with a nut ring I that is threadedly engaged with it, the shortening adjustment bolt is inserted from the head end of the contact seat and extends into the contact box, the contact box is provided with a nut ring II that is threadedly engaged with it.

[0006] The present invention is further configured such that: the contact head is cylindrical with a height of 8mm, and the contact plate seat is square with a side length of 15mm.

[0007] By adopting the above technical solutions, using all-copper contact heads and contact bases significantly improves oxidation and rust resistance, avoids conductivity degradation caused by humid environments or chemical corrosion, extends device lifespan, and reduces maintenance costs. The optimized contact head height adjustment structure allows for flexible adjustment of contact head height, adapting to different wire diameters, installation angles, or wiring scenarios, improving versatility and ease of installation, and reducing replacement or modification issues caused by size mismatches. The increased contact base area ensures effective contact even with slight installation position deviations, avoiding power failure caused by misalignment of traditional small-sized contacts, and significantly improving the stability and safety of circuit connections.

[0012] Reference Figures 1 to 3 The embodiments of this utility model will be further described below.

[0013] A contact over-line protector, characterized in that it comprises a contact housing and a contact plate housing. The contact housing has a sliding cavity with an opening, and a contact seat is slidably fitted inside the sliding cavity. One end of the contact seat is provided with a plurality of contact heads extending from the opening of the sliding cavity, and the other end is provided with a wiring terminal. The wiring terminal passes through the bottom wall of the sliding cavity and extends out of the contact housing. The contact seat is also provided with an adjustment structure for adjusting the height of the contact heads extending out of the contact housing. The contact plate housing has a number of contact plate seats equal to the number of contact heads. Both the contact heads and the contact plate seats are made of copper.

[0014] The adjustment structure includes an extension adjustment bolt and a shortening adjustment bolt. The extension adjustment bolt passes through the tail end of the contact box into the sliding cavity and extends into the contact seat. A first nut ring with a threaded engagement is provided inside the contact seat. The shortening adjustment bolt passes through the head end of the contact seat and extends into the contact box. A second nut ring with a threaded engagement is provided inside the contact box. The contact head is cylindrical with a height of 8mm, and the contact plate seat is square with a side length of 15mm.

[0015] Working principle: During installation, the contact box and contact plate box can be assembled separately, optimizing installation convenience. The improved materials of the contact head and contact base, made of copper, significantly enhance oxidation and rust resistance, preventing conductivity degradation due to humidity or chemical corrosion, extending device lifespan, and reducing maintenance costs.

[0016] When the height of the contact head needs to be extended, the extension adjustment bolt is screwed on, engaging with the nut ring, driving the contact seat to move continuously towards the opening of the slide cavity, thus increasing the height of the contact head extending out of the contact box. Conversely, the shortening adjustment bolt is screwed on, driving the contact seat towards the bottom wall of the slide cavity, thus shortening the contact head height. The addition of an adjustment mechanism allows for adjustment according to different usage environments, offering the advantage of wide applicability. The contact head is cylindrical, and the contact seat is square, increasing the contact seat area and achieving point-to-surface contact. Even with slight deviations in installation position, effective contact is ensured, avoiding energization failure caused by misalignment of traditional small-sized contacts, significantly improving the stability and safety of circuit connections. Extending the contact head height flexibly adapts to the needs of different wire diameters, installation angles, or wire routing scenarios, enhancing versatility.

[0017] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
