Description

Technical Field

[0001] This utility model belongs to the field of terminal block technology, specifically a corrosion-resistant copper alloy terminal block. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections. Industrially, they fall under the category of connectors. Terminal blocks are used to facilitate the connection of wires. They are essentially metal connectors encased in insulating plastic, with holes at both ends for inserting wires. Terminal blocks can be divided into WUK terminal blocks, European terminal block series, pluggable terminal block series, etc. Copper alloy terminal blocks have gradually developed to the point that they have corrosion resistance, thus extending their service life.

[0003] Meanwhile, a terminal block with application number CN202420049437.3 includes a connecting strip, on one side of which are provided a plurality of terminal blocks. A connecting hole is opened on the top surface of the connecting strip, and the connecting hole is located between two of the terminal blocks. The terminal block includes a contact piece, a lead, and a lead pin. One end face of the contact piece is fixedly connected to one side of the connecting strip, and the lead pin is fixedly connected to one side of the contact piece. An upward-facing lead is fixedly connected to both sides of the top of the contact piece, and the lead is disposed between the lead pin and the connecting strip.

[0004] However, the following problems were found in the implementation of the relevant technology: the lack of a protective structure makes it easy for dust to accumulate on the top of the terminal block, which is not conducive to subsequent cleaning. If this dust accumulation continues, it will affect the use of the terminal block. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a corrosion-resistant copper alloy terminal block that is dustproof, thereby reducing dust accumulation inside the terminal block.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant copper alloy terminal block, comprising a copper alloy terminal block main housing, a terminal sleeve connected to the inner side of the copper alloy terminal block main housing, two crimping bolts threaded to the top of the terminal sleeve, two copper alloy terminal block sub-housings connected to the top of the copper alloy terminal block main housing, protective components provided on the inner side of each of the two copper alloy terminal block sub-housings, and four fixing rods connected to the inner side of each of the two copper alloy terminal block sub-housings.

[0007] Preferably, both of the protective components include a built-in fixing rod and four protective sponges. The two built-in fixing rods are respectively set inside the two copper alloy terminal sub-housings via four corresponding fixing rods. The surfaces of the two built-in fixing rods are rotatably connected to four built-in sliders. One side of each of the eight built-in sliders is connected to a protective plate. The top of each of the eight protective plates is connected to several retraction springs. Each set of four protective sponges is set inside the copper alloy terminal sub-housing.

[0008] Preferably, the other side of each of the four built-in sliders is respectively attached to the inner wall of each of the copper alloy terminal housings.

[0009] Preferably, the top end of the corresponding retraction spring is connected to the inner wall of the two copper alloy terminal housings respectively.

[0010] Preferably, each of the protective sponges is located directly below each of the protective panels.

[0011] Preferably, the surfaces of both crimping bolts are threaded to the inner top of the main housing of the copper alloy terminal block.

[0012] Preferably, the surfaces of the main housing of the copper alloy terminal block, the terminal sleeve, and the sub-housings of the two copper alloy terminal blocks are all coated with a corrosion-resistant coating.

[0013] Preferably, the surface of the corrosion-resistant coating is coated with an insulating varnish.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model facilitates crimping of the wires to be connected by using a wire sleeve and a crimping bolt. The rotational connection of the built-in slider allows the protective plate to have an inclined force, which allows the protective plate to be pressed downwards when an electric screwdriver is needed to tighten the crimping bolts to the main housing of the copper alloy terminal and the wire sleeve, without affecting the thread fixation of the crimping bolts. At the same time, the contraction action of the retraction spring ensures that the protective plate is always close to a closed state when not under pressure, which helps to provide a good dustproof effect to the inside of the secondary housing of the copper alloy terminal, preventing the accumulation of dust inside the secondary housing of the copper alloy terminal and improving the overall wiring effect of the main housing of the copper alloy terminal.

[0016] 2. This utility model utilizes a soft protective sponge that not only provides dust protection but also absorbs water. This helps absorb any water droplets accidentally falling into the copper alloy terminal sub-housing, preventing direct entry and protecting the wiring inside the main copper alloy terminal housing. Furthermore, the corrosion-resistant coating provides excellent corrosion resistance to both the main and sub-housing housings. An insulating varnish is applied to the surface of the corrosion-resistant coating, providing good insulation and enhancing the overall safety of the copper alloy terminal housing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 6As shown, this utility model provides a corrosion-resistant copper alloy terminal block, including a copper alloy terminal block main housing 1, a terminal sleeve 3 connected to the inner side of the copper alloy terminal block main housing 1, two crimping bolts 4 threadedly connected to the top of the terminal sleeve 3, two copper alloy terminal block sub-housings 5 ​​connected to the top of the copper alloy terminal block main housing 1, a protective component 2 provided on the inner side of each of the two copper alloy terminal block sub-housings 5, and four fixing rods connected to the inner side of each of the two copper alloy terminal block sub-housings 5.

[0028] Specifically, both protective components 2 include built-in fixing rods 21 and four protective sponges 25. The two built-in fixing rods 21 are respectively set inside the two copper alloy terminal sub-housings 5 ​​through the corresponding four fixing rods. The surfaces of the two built-in fixing rods 21 are rotatably connected to four built-in sliders 22. One side of each of the eight built-in sliders 22 is connected to a protective plate 23. The top of each of the eight protective plates 23 is connected to several compression springs 24. Each set of four protective sponges 25 is set inside the copper alloy terminal sub-housing 5.

[0029] Furthermore, the other side of each of the four built-in sliders 22 is respectively attached to the inner wall of each copper alloy terminal housing 5.

[0030] Furthermore, the top of the corresponding retraction spring 24 is connected to the inner wall of the two copper alloy terminal housings 5 ​​respectively.

[0031] It is worth noting that each protective sponge 25 is located directly below each protective plate 23.

[0032] It is worth noting that the surfaces of both crimping bolts 4 are threaded to the inner top of the main housing 1 of the copper alloy terminal block.

[0033] It is worth mentioning that the surfaces of the main housing 1 of the copper alloy terminal block, the terminal sleeve 3, and the two secondary housings 5 ​​of the copper alloy terminal block are all coated with corrosion-resistant paint.

[0034] It is worth emphasizing that the surface of the corrosion-resistant coating is coated with insulating varnish.

[0035] Among them, the protective sponge 25, the wiring sleeve 3, and the crimping bolt 4 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller, and a switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0036] Working principle: First, insert the required connector into the main housing 1 and connector sleeve 3 of the copper alloy terminal block. Then, insert an electric screwdriver into one of the secondary housings 5 ​​of the copper alloy terminal block. Since the built-in slider 22 is rotatably connected to the built-in fixing rod 21, the rotating head of the electric screwdriver presses the four protective plates 23 downwards from the center under the rotation of the built-in slider 22, and also presses open the center of the four soft protective sponges 25. This threadedly fixes the crimping bolt 4 to the secondary housing 5 and the main housing 1 of the copper alloy terminal block. The downward pressing action of the crimping bolt 4 fixes the connector to the main housing 1 of the copper alloy terminal block, thus completing the wiring operation. After installing the crimping bolt 4, remove the electric screwdriver. When the corresponding spring 24 contracts, it can cause the corresponding protective plate 23 to tilt and return to its original position. The shielding effect of the protective plate 23 and the protective sponge 25 not only helps to reduce dust accumulation, but also the water absorption effect of the protective sponge 25 helps to absorb water droplets that may accidentally drip into the interior of the copper alloy terminal sub-housing 5, thus providing a certain degree of waterproof protection for the terminals inside the copper alloy terminal sub-housing 5. Furthermore, both the main housing 1 and the sub-housing 5 of the copper alloy terminal are coated with corrosion-resistant paint, thus providing good corrosion resistance. An insulating varnish is also coated on the surface of the corrosion-resistant coating, thus providing good insulation and improving the overall safety of the main housing 1 of the copper alloy terminal.
