Description

Technical Field

[0001] The utility model belongs to the field of wiring terminals, in particular to a two-input and one-output wiring terminal. Background Art

[0002] Terminal blocks usually refer to a device or component used for electrical connection, which is used to connect wires or cables in a circuit to facilitate the wiring connection of electrical equipment or circuits. These terminals are usually designed to be fixed on electronic equipment or appliances to safely connect wires, avoid short circuits or poor contact, and ensure the normal operation and safety of the circuit.

[0003] The more common terminal blocks include screw terminals for fixing circuits with screws, crimping terminals for fixing circuits by pressing, pin terminals for plug-in connections, and snap-on terminals for clamping circuits by snaps. Various types of terminals are usually designed in standardized styles to facilitate the interconnection and maintenance of different devices and circuits. Correct use of terminal blocks can effectively ensure the stability of circuit connections and facilitate the later maintenance of various equipment.

[0004] However, there is no good solution for multi-input and one-output terminal blocks in the current existing technology. The most common wiring method is to force multiple wires into the same terminal slot. However, this wiring method has poor wiring stability and is not convenient for later inspection and maintenance.

[0005] Therefore, a new design of wiring terminal is needed that can meet the requirements of simultaneous multi-directional line input and single-line output. Utility Model Content

[0006] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a two-input and one-output terminal.

[0007] In order to solve the above problems, the technical solution adopted by the utility model is as follows:

[0008] A two-input and one-output terminal comprises a shell and a conductive sheet, wherein the conductive sheet is arranged in a cavity inside the shell, two wiring holes are arranged on the shell, and the middle part of the two wiring holes is an unlocking button movably connected to the shell, a group of spring sheets are symmetrically arranged on the conductive sheet, the spring sheets correspond to the wiring holes, the gaps between the spring sheets match the unlocking button, and the conductive sheet is provided with a clip for connecting an output wire.

[0009] The conductive sheet and the clamping sheet are an integrated structure.

[0010] The shape of the shell matches the structure of the conductive sheet.

[0011] The shell is provided with a wire outlet hole matching the clip part.

[0012] The left and right side walls of the shell are detachable structures.

[0013] The outer side walls of the shell are structures that can be assembled with each other.

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

[0015] The structure of the utility model integrates multiple connection directions, providing multiple connection direction options for the port connection of the device. The direct plug-in connection method makes wiring easier. When the connection needs to be disconnected, you only need to press the unlock button to disconnect the two wires at the same time, thereby improving operating efficiency. Although the design of the integrated structure of the conductive sheet and the spring makes the conductive sheet structure complicated, it eliminates the potential risk of connection stability of the two-piece conductive sheet, and with the insulating shell specially involved for the conductive sheet, it is also very convenient for maintenance and replacement. The main body that realizes the function of connecting and fixing the wires is all on the conductive sheet. When repairing, the entire conductive sheet can be directly taken out for replacement. Compared with the common ports on the market that are fixed by screws, there is no problem of screw stripping or partial damage to the fixing screws of the shell, which can only be replaced as a whole.

[0020] The utility model is further described below in conjunction with specific embodiments.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model mainly includes a housing 1 and a conductive sheet 3 .

[0022] The specific structure of the conductive sheet 3 is as follows: Figure 3As shown, the conductive sheet 3 is mainly divided into a conductive sheet 3 body, a spring sheet 4 and a clamping sheet 5, all of which are integrated structures. In this embodiment, a two-in-one-out terminal structure is mainly shown, so the spring sheet 4 is a structure symmetrically arranged at an angle of 45°. When the connector of the wire enters the gap between the spring sheet 4 and the conductive sheet 3, the spring sheet 4 is squeezed by the wire connector, providing a reverse elastic squeezing force for the wire connector, thereby squeezing and fixing the wire connector between the spring sheet 4 and the conductive sheet 3.

[0023] Based on the design of the conductive sheet 3 in this embodiment, Figure 3 This structure can accommodate the connectors of two wires at the same time and fix them separately. The two spring pieces 4 structures are independent of each other. If one of the wiring parts is not wired, it will not affect the other spring piece 4 structure. Users can choose two in and one out or one in and one out according to actual conditions, or use it to adjust the connection angle of the wire connector. It is very flexible to use.

[0024] The outer side of the spring sheet 4 structure of the conductive sheet 3 is a clip 5 portion that is additionally extended from the conductive sheet 3, such as Figure 2 As can be seen from the internal structure diagram, the main function of the clip 5 part is to connect with the output wire. The connector of the output wire is connected from the clip 5 part, and the wire connector is clamped by the structure of the clip 5 to ensure the stable connection of the output wire.

[0025] The conductive sheet 3 is installed in the inner cavity of the insulating housing 1. The main structure of the housing 1 is as follows. Figure 1 and Figure 2 As shown, its shape is mainly designed according to the structure of the conductive sheet 3.

[0026] The surface of the housing 1 is mainly provided with a wiring hole 6 and a wire outlet hole 7. Since the conductive sheet 3 in this embodiment has a two-in and one-out structure, two wiring holes 6 are provided, which correspond to the positions of the two spring sheets 4 on the conductive sheet 3 for connecting the wire connectors. The portion between the two wiring holes 6 can move within a certain range relative to the housing 1, and its internal structure is designed to avoid the conductive sheet 3 and contact the spring sheets 4 when moving toward the internal cavity of the housing 1. Figure 2 As shown, the spring sheet 4 is further compressed by moving toward the inside of the housing 1, so that the spring sheet 4 can unlock the wire connector, and the movable portion of the housing 1 serves as the unlocking button 2 of the terminal block.

[0027] The part corresponding to the clamp 5 at the other end of the shell 1 is provided with a wire outlet hole 7. The connector of the wire is connected to the shell 1 from the wire outlet hole 7 and contacts the conductive sheet 3, and is clamped and fixed by the clamp 5. The wiring hole 6 on the other side of the shell 1 is also connected to the connector of the wire and is clamped and fixed by the spring 4. The three wires are connected to the shell 1 at the same time and are interconnected through a whole conductive sheet 3, realizing two-in and one-out wiring of the wires.

[0028] Although the wiring method emphasized in the embodiment and the title of the utility model is two-in and one-out, the connection method is not unidirectional. The reason for emphasizing two-in and one-out is that due to the structure of the spring 4 and the setting of the unlocking button 2, the two wiring contacts on one side of the wiring hole 6 are more convenient for the disassembly and assembly of the wire connector, and the structure of the spring 4 is more suitable for frequent wire plugging and unplugging compared to the clip 5. Therefore, in actual use, it is more convenient to use the wiring hole 6 on the side of the spring 4 as the frequent plugging and unplugging incoming line port. However, when it is necessary to use the structure as one-in and two-out, the one-in and two-out function can also be realized.

[0029] The left and right sides of the shell 1 are both detachable structures, which can facilitate maintenance personnel to directly replace the conductive sheet 3 in the shell 1 during maintenance, and the entire insulating shell 1 can be designed as a modular structure, and its smallest working unit is a two-input and one-output structure with only one conductive sheet 3. In actual production, the lateral number of the shell 1 can be extended according to the requirements of the specific number of ports to provide more wiring holes 6 and outlet holes 7. The attached figure provided in this specification is a combined wiring terminal composed of three minimum module extensions.
