Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, and in particular to a terminal block that facilitates wiring. Background Technology

[0002] Terminal blocks, as an indispensable basic component in the field of electrical connections, are widely used in many scenarios such as power systems, industrial control, home appliances and communication equipment. Their core function is to realize safe, reliable and efficient electrical connections between wires.

[0003] In existing technologies, terminal blocks using "C"-shaped or "U"-shaped spring clip structures for crimping wires can simplify operation to some extent. However, these structures typically require the wires to be inserted axially along the terminal, enabling only butt or branch connections of wires in the same straight direction, and are mostly unidirectional crimps, making them difficult to adapt to the varying spatial orientations of wires in complex wiring environments. When two wires need to be connected in a cross-shaped manner, the conventional approach is to cut the wires to be connected and connect them to the two interfaces of the terminal, or to use multiple connection points with auxiliary components such as connector lugs and connector caps for conversion. In other words, if a branch line needs to be drawn from the original line, traditional terminals often require cutting the main line to insert it into the terminal, which can damage the line and affect the integrity of the original circuit, hindering rapid maintenance and non-destructive connection.

[0004] Therefore, existing terminal blocks still have significant shortcomings in handling cross-shaped wire connections, non-destructive access, and flexible wiring. This application addresses these technical problems by making improvements. Utility Model Content

[0005] This invention proposes a terminal block that facilitates wiring, enabling cross-shaped connections of wires without cutting them, thus meeting the need for flexible wiring in space and solving the aforementioned problems existing in the prior art.

[0006] The technical solution of this utility model is implemented as follows: a terminal block for easy wiring includes an integrally formed first clamping end, a second clamping end, and a middle connecting section. The first clamping end and the second clamping end are arranged perpendicularly and are both connected to the connecting section. The cross-sections of the first clamping end and the second clamping end are both U-shaped. The first clamping end and the second clamping end are arranged in opposite directions. Both the first clamping end and the second clamping end have wire passage grooves. The opening of the wire passage groove of the first clamping end faces forward, and the opening of the wire passage groove of the second clamping end faces backward.

[0007] Preferably, both the first clamping end and the second clamping end are provided in twos.

[0008] Preferably, the middle connecting section is cross-shaped, with two first clamping ends symmetrically arranged at two ends of the connecting section, and two second clamping ends symmetrically arranged at the other two ends of the connecting section.

[0009] Preferably, the first clamping end and the second clamping end are integrally formed with a clamping strip on one side of the opening position of the wire groove.

[0010] Preferably, the first clamping end and the second clamping end are integrally formed with a limiting strip on the side away from the clamping strip.

[0011] Preferably, the first clamping end and the second clamping end are also fixedly connected to a limit block on the side away from the clamping strip.

[0012] Preferably, the end of the wire-holding strip has a raised section.

[0013] In summary, the beneficial effects of this utility model are as follows: 1. This application utilizes an integrally formed first clamping end, second clamping end, and central connecting section, arranged perpendicularly and in opposite directions to form a spatially orthogonal U-shaped clamping structure. This structure allows two wires to be connected in a cross shape without cutting: one wire passes through the forward groove of the first clamping end along a first direction, and the other wire passes through the backward groove of the second clamping end along a vertical direction. The two clamping ends are then pressed onto the corresponding wires to complete the electrical connection. This design overcomes the limitations of traditional terminal blocks, which can only achieve coaxial or parallel connections. It eliminates the need to cut wires or use additional connectors, significantly improving wiring efficiency and ease of construction. It is particularly suitable for scenarios with limited space or requiring rapid wiring, while also avoiding damage to the line integrity caused by wire cutting, thus improving safety and maintainability.

[0014] 2. When both the first and second clamping ends are provided in pairs, a double-point clamping structure can be formed in two mutually perpendicular directions. Compared with a single-sided single-clamping structure, the double-clamping end design significantly enhances the clamping force and contact area of ​​the incoming conductor, effectively preventing the conductor from loosening or slipping, and improving the stability and mechanical strength of the electrical connection. Furthermore, when subjected to vibration or external tensile forces, the double-point crimping can evenly distribute the force, reduce local stress concentration, extend the terminal's service life, and further ensure the long-term reliability of the connection.

[0018] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example 1: like Figure 1 As shown, this utility model discloses a terminal block that facilitates wiring. It is manufactured using a metal spring stamping and bending process, preferably employing phosphor bronze or tin-phosphor bronze strip as the base material. This results in excellent conductivity, a high elastic limit, and good fatigue resistance, maintaining stable resilience and clamping force even after multiple crimping operations. To improve corrosion resistance and contact surface conductivity, the entire terminal surface can be silver-plated, or tin-plated or nickel-plated alternatives.

[0020] The terminal block specifically includes an integrally formed first clamping end 1, a second clamping end 2, and a middle connecting section 3. The first clamping end 1 and the second clamping end 2 are arranged perpendicularly and are both connected to the connecting section. The cross-sections of the first clamping end 1 and the second clamping end 2 are both U-shaped. The first clamping end 1 and the second clamping end 2 are arranged in opposite directions. The first clamping end 1 has a wire passage groove 4 with its opening facing the front side, and the second clamping end 2 has a wire passage groove 4 with its opening facing the rear side. Since the opening directions of the two wire passage grooves 4 are opposite and located on different planes, the two wires can be non-intrusively cross-connected without being cut.

[0021] like Figure 2 As shown, two wires can be connected in a cross shape without being cut: one wire passes through the forward groove 4 of the first clamping end 1 in the first direction, and the other wire passes through the backward groove 4 of the second clamping end 2 in the vertical direction. Then, the two clamping ends are pressed onto the corresponding wires to complete the electrical connection.

[0022] Example 2: like Figure 3 As shown, compared to Example 1, Example 2 has two first clamping ends 1 and two second clamping ends 2. Furthermore, the central connecting section 3 is cross-shaped, with each of its four extended arms connected to a clamping end, forming a symmetrical layout. Specifically, the two first clamping ends 1 are symmetrically arranged at one set of diagonal ends of the cross-shaped connecting section, used to clamp the two sides of the same wire, achieving dual-point fixation; the two second clamping ends 2 are symmetrically arranged at another set of diagonal ends, used to clamp another wire in the vertical direction. This four-arm cross structure not only improves overall rigidity and installation stability but also ensures a uniform distribution of crimping force, avoiding terminal twisting or wire displacement due to force eccentricity.

[0023] Example 3: like Figure 4 As shown, in Embodiment 3, compared to Embodiments 1 and 2, both the first clamping end 1 and the second clamping end 2 have an integrally formed clamping strip 5 on one side of the opening of the wire groove 4. The root of the clamping strip 5 is connected to the main body of the clamping end, and the free end is slightly curved outward to form a raised section 51. After the wire is inserted into the wire groove 4, a special crimping pliers are used to fold the clamping strip 5 downward and make it wrap around the outer circumference of the wire, finally adhering to the back of the wire to form a ring-shaped wrapping structure. This process is completed by the plastic deformation of the metal material, so that sufficient contact pressure is generated between the clamping strip 5 and the wire to ensure a low-resistance, high-reliability electrical connection.

[0024] The first clamping end 1 and the second clamping end 2 are integrally formed with a limiting pressure strip 6 on the side away from the wire clamping strip 5 (that is, on the opposite side of the wire clamping strip 5). One end of the limiting pressure strip 6 is fixed to the clamping end body, and the other end extends freely. After the wire clamping strip 5 is folded over and covers the wire, the limiting pressure strip 6 can be pressed laterally on its outside to prevent the wire clamping strip 5 from springing back. To further enhance the locking effect, the first clamping end 1 and the second clamping end 2 are also fixedly connected with a limiting block 7 by welding on the side away from the wire clamping strip 5. The limiting block 7 and the limiting pressure strip 6 are located on both sides of the wire clamping strip 5, forming a mechanical clamping boundary, which effectively limits the deviation of the wire clamping strip 5. In addition, the wire clamping strip 5 can also be provided with a slot 52 for the limiting block 7 and the limiting pressure strip 6 to engage. Finally, after the limiting strip 6 is pressed down laterally and adheres to the surface of the wire-holding strip 5, the raised section 51 at the free end of the wire-holding strip 5 can be folded in the opposite direction using a tool, so that it fits tightly against the body of the limiting strip 6, forming a locking structure. This folding action increases the difficulty of disassembly and improves the anti-loosening performance.
