Description

Technical Field

[0001] The utility model designs the technical field of connecting wires, in particular to a connecting terminal. Background Art

[0002] The terminal block is a commonly used accessory in electrical engineering, which is mainly used to achieve electrical connection and make wire connection more convenient. It is actually a piece of metal sheet sealed in insulating plastic, with holes at both ends for inserting wires, and screws for tightening or loosening. In this way, when the wire needs to be connected or disconnected, the terminal can be used to switch at any time without welding or twisting the wires together. Its connection method is flexible and widely used in electrical equipment. There are no protective covers at both ends of the commonly used terminal blocks, and they are generally connected with connecting wires 5 when used. However, on the one hand, some special equipment has external functional modules when used, such as multi-functional bag making machines. When the multi-functional bag making machine produces self-supporting bags, it is necessary to add self-supporting bag functional modules, and remove the self-supporting bag functional modules for other bag types. When such equipment does not use external functional modules, there is no connecting wire in the connecting hole corresponding to the terminal block, and the wiring frame is half exposed to the air, resulting in a decrease in electrical insulation performance. In some special occasions, there are greater safety hazards. On the other hand, when the connecting wire 5 at one end of the circuit is removed, the circuit is often easily exposed to the outside, increasing the risk of electrical failure and safety hazards.

[0038] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0039] like Figure 1-Figure 8 As shown, the utility model provides a terminal block, including a housing 1, a wiring frame 2, and a plug connector 3. The wiring frame 2 is located in the housing 1. The plug connector 3 passes through the housing 1 and is connected to the wiring frame 2. The housing 1 is provided with a first opening 11 and a second opening 12. The second opening 12 is provided with a protective cover 4. The wiring frame is provided with a first wiring port corresponding to the first opening and a second wiring port corresponding to the second opening. Two connecting wires 55 enter the wiring frame 2 through the first opening 11 of the housing 1 and are connected to the wiring frame 2 through the plug connector 3. The protective cover 4 can block the connecting wires 5 to prevent the connecting wires 5 from being exposed outside the housing 1, thereby reducing the risk of electrical failure.

[0040] Furthermore, the connection between the protective cover 4 and the housing 1 is arranged to be fixedly connected, detachably connected, or movably connected.

[0041] like Fig. 9 As shown, when using the terminal block, the two-wire connection only requires inserting the two connecting wires 5 into the first wiring port 21 of the wiring frame 2 and tightening the corresponding screws, without removing the protective cover 4. Specifically, the fixed connection between the housing 1 and the protective cover 4 can be integrally formed, and it can be understood that the integral forming method can improve the connection strength of the protective cover 4, so that the overall structural strength of the terminal block is higher.

[0042] like Figure 10-11 As shown, when it is necessary to introduce wires from the first opening 11 and the second opening 12 respectively, in order to conveniently and quickly remove the protective cover 4, it is preferred to design a notch at the connection between the housing 1 and the protective cover 4. These notches can be used as a fulcrum for prying up or cutting off the protective cover 4, so that the user can operate easily. It can be imagined that the protective cover 4 is connected to the housing 1 by a connecting rib, and the protective cover 4 can be removed using a simple tool. When a three-wire connection is required, the protective cover 4 is removed and the third connecting wire 5 is connected at the second wiring port 22.

[0043] The detachable connection between the protective cover 4 and the housing 1 is suitable for occasions where disassembly and assembly are frequently required. Specifically, the protective cover 4 and the housing 1 are connected by a snap-fit ​​structure. This connection method is convenient and quick, and does not require additional tools. The user can fix or remove the protective cover 4 on the housing 1 through simple operations. In the case where the functional module needs to be frequently disassembled and assembled, the connecting wire 5 of the functional module is preferably connected from the second opening 12, so that when the connecting wire 5 is disassembled and assembled, other circuit parts are not involved, and poor circuit contact failure is not likely to occur.

[0044] The movable connection between the protective cover 4 and the housing 1 is suitable for occasions where the connecting wire 5 needs to be frequently operated, as long as the housing 1 that covers the second opening 12 when protection is required can be opened when the connecting wire 5 is inserted. Specifically, the movable connection allows the protective cover 4 to move or rotate freely on the housing 1, and a structure such as a slide rail or a rotating shaft is provided between the housing 1 and the protective cover 4, so that it can move or rotate smoothly, and the user can easily open the protective cover 4 and insert or unplug the connecting wire 5 when needed.

[0045] In order to facilitate the connection of the external circuit, the first opening 11 of the housing is larger than the second opening 12. The end faces of the first opening 11 and the second opening 12 are set in a D shape. As the insertion port of the connecting wire 5, the first opening 11 can guide the inserted connecting wire 5 on the one hand, which is more conducive to the insertion of the connecting wire 5 into the wiring frame 2; on the other hand, by setting the large-sized first opening, the distance between the connecting wire 5 and the housing 1 is increased to a certain extent, thereby increasing the creepage distance and reducing the risk of electrical failure. Specifically, the first opening 11 of the housing 1 is set as a bell mouth, the large mouth of the bell mouth faces outward, and the size of the small mouth is consistent with the size of the first wiring port 21 of the wiring frame 2 or slightly smaller than the first wiring port 21 of the wiring frame 2. The bell mouth can guide the connecting wire to prevent the conductive part of the connecting wire from leaking out, and at the same time prevent the connection between two adjacent wiring terminals to avoid electric shock to the operator.

[0046] In the above embodiment, the wiring frame 2 is provided with a first wiring port 21 corresponding to the first opening 11 and a second wiring port 22 corresponding to the second opening 12, and the first wiring port 21 is larger than the second wiring port 22. The connecting wire 5 that does not need to be frequently disassembled is put together with the incoming wire, inserted into the first wiring port 21 of the wiring frame 2, and fixed with the connector 3. The connecting wire 5 that needs to be frequently disassembled is inserted into the second wiring port 22 of the wiring frame 2, and the already paralleled wires are not affected during disassembly and assembly. The design of one end being larger and the other end being smaller expands the use range of the wiring terminal, making the connection more convenient. When in use, it can be switched between one incoming wire and one outgoing wire, or one incoming wire and two outgoing wires at will.

[0047] Furthermore, the connection terminals are arranged in rows, which improves the efficiency and aesthetics of wiring. By arranging the connection terminals neatly, electrical faults caused by chaotic connection or poor contact of the connection wires can be reduced. Preferably, the connection terminals in a row can be cut into different digits for use as needed, such as two digits for connection to two groups of connection wires, three digits for connection to three groups of connection wires, and so on. Preferably, the connection terminals arranged in a row are connected by thin sheets, and the connection terminals can be cut into different digits for use as needed using simple tools.

[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the scope of the utility model patent shall be based on the attached claims.
