Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to an N-phase terminal block. Background Technology

[0002] Existing N-phase terminal blocks are typically fixed to the terminals by welding or screws, which makes the connection process cumbersome and inconvenient. Furthermore, if either the N-phase terminal block or the terminal block is damaged, both the N-phase terminal block and the terminal block must be replaced, resulting in high scrap costs. In addition, existing N-phase terminal blocks generate heat during use. When too much heat accumulates, it will cause the N-phase terminal block to age faster, increase resistance, and thus affect electrical performance.

[0003] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Utility Model Content

[0004] The present invention provides an N-phase terminal block to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An N-phase terminal block includes a terminal block and terminals. The terminal block has connecting blocks at both ends and latches on both sides. The terminal block has heat dissipation grooves on its surface. The terminals include connecting blocks and connecting grooves on one side. Pressure rods are provided on both sides of the connecting groove. The pressure rods have latches on the inner side of their tops and pressing blocks on the outer side of their bottoms. The connecting blocks are inserted into the connecting grooves, and latches engage with each other.

[0007] Preferably, both sides of the connecting groove are provided with bosses, and the bosses are in close contact with the surface of the connecting block.

[0008] Preferably, the corners of the opposite ends of the first and second buckles are both beveled.

[0009] Preferably, the wiring block has a wiring hole and a wire clamping screw is screwed onto the wiring block.

[0010] Beneficial effects

[0011] The above-mentioned technical solutions of one or more of the N-phase terminal blocks provided in this utility model embodiment have at least one of the following technical effects:

[0012] This utility model, through the aforementioned technical solution, enables the connection block to be inserted into the connection slot when the terminal block is connected to the terminal block, allowing the first and second clips to engage, enabling plug-and-play functionality without the need for welding or screws, thus accelerating the connection process. Furthermore, by pressing the pressing block, the pressure rod deforms, causing the second clip to move away from the first clip, allowing the connection block to be pulled out of the connection slot. This facilitates disassembly of the terminal block and terminal blocks, eliminating the need to replace both the terminal block and terminal blocks together during replacement, reducing disposal costs. Additionally, the presence of heat dissipation grooves on the surface of the terminal block increases the contact area between the N-phase terminal block and the air, thereby increasing heat dissipation efficiency.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, 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.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1-4 The diagram shown is a structural schematic of an N-phase terminal block according to a preferred embodiment of the present invention.

[0023] In this embodiment, a wiring board 1 and a terminal block 2 are included. The wiring board 1 has connecting blocks 3 at both ends, and the connecting blocks 3 have first buckles 4 on both sides. The surface of the wiring board 1 has heat dissipation grooves 5. The terminal block 2 includes a wiring block 6. The wiring block 6 has a connecting groove 7 on one side. The connecting groove 7 has pressure rods 8 on both sides. The pressure rods 8 have second buckles 9 on the inner side of their tops and pressing blocks 10 on the outer side of their bottoms. The pressure rods 8 have a lever effect. The connecting blocks 3 are inserted into the connecting grooves 7, and the first buckles 4 are engaged with the second buckles 9. When the terminal block 1 is connected to the terminal block 2, the connecting block 3 is inserted into the connecting groove 7, so that the first latch 4 and the second latch 9 are engaged, allowing for plug-and-play operation without the need for welding or screws, thus speeding up the connection process. Furthermore, by pressing the pressing block 10, the pressure rod 8 is deformed, causing the second latch 9 to move away from the first latch 4, thereby allowing the connecting block 3 to be pulled out of the connecting groove 7. This facilitates the disassembly of the terminal block 1 and the terminal block 2, eliminating the need to replace both the terminal block 1 and the terminal block 2 together during replacement, reducing scrap costs. In addition, the heat dissipation grooves 5 on the surface of the terminal block 1 increase the contact area between the terminal block 1 and the air, thereby increasing the heat dissipation efficiency.

[0024] In this embodiment, both side walls of the connecting groove 7 are provided with protrusions 11, and the protrusions 11 are in close contact with the surface of the connecting block 3. This ensures the effective contact between the connecting groove 7 and the connecting block 3.

[0025] In this embodiment, the opposite corners of the first buckle 4 and the second buckle 9 are both beveled. The beveled structure makes it easier for the first buckle 4 to be inserted into the connecting slot 7.

[0026] In this embodiment, the connector 6 has a wiring hole 12, and a wire clamping screw 13 is screwed onto the connector 6. When wiring, the wire is inserted into the wiring hole 12, and the wire clamping screw 13 is tightened to clamp the wire into the wiring hole 12.

[0027] The N-phase terminal block of this utility model can be installed, connected, or set in a common mechanical manner, and can be implemented as long as it can achieve its beneficial effect.

[0028] All technologies not described in detail in this utility model are known technologies. Those skilled in the art can easily implement this utility model based on their understanding of this specification, and the contents shown in the accompanying drawings are part of this specification.

[0029] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
