Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical technology, specifically to a measuring switch with multiple wiring frames. Background Technology

[0002] In low-voltage power distribution systems, measuring switches are widely used in power metering, monitoring, and control circuits. Traditional measuring switches typically have a single-wire terminal structure, allowing only one wire to be connected per phase. In compact installation scenarios such as distribution cabinets, it is often necessary to distribute one power supply to multiple loads or measurement units. This requires additional crimping lugs or adapters, leading to inconvenience in installation and maintenance. Furthermore, multi-wire crimping can result in poor contact and may introduce additional contact resistance and potential fault points. Therefore, there is an urgent need for a measuring switch that integrates multi-wire connection capability, has a compact structure, reliable connection, and is easy to install. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a measuring switch with multiple wiring frames.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A measuring switch with multiple terminal blocks includes a housing having several phase wire channels, and inlet terminals and outlet terminals respectively disposed at both ends of the phase wire channels.

[0006] The outgoing terminal includes:

[0007] The wire divider has at least two wiring channels divided on its wiring surface, and a locking channel is provided in the direction perpendicular to the wiring channel, and the locking channel is connected to the wiring channel.

[0008] Several wiring frames are respectively disposed in the wiring channel, and the tightening parts of each wiring frame are movably disposed in the corresponding locking channel;

[0009] The first terminal block has multiple branch terminal blocks at its front end, with each branch terminal block extending into its corresponding terminal frame.

[0010] There are four wiring channels, which are divided into two groups, one above the other, and each group includes two wiring channels arranged side by side. The locking channels are divided into two groups, one in front and one behind, and each group includes two locking channels arranged side by side.

[0011] The front end of the first terminal block forks to form two first branch terminal blocks, which extend into the two sets of terminal frames on the lower side respectively.

[0012] The first terminal block is also provided with a second terminal block at its front end. One end of the second terminal block is electrically connected to the first terminal block, and the other end is forked to form two second branch terminal blocks, which extend into the two sets of terminal frames on the upper side respectively.

[0013] Two wiring frames located in the same column are staggered along the wiring direction.

[0014] The second terminal block has a through hole through which the rear tightening member can pass.

[0015] The housing includes a base and a pedestal, and the base and pedestal cooperate to form an installation space for accommodating the outgoing terminals.

[0016] The bottom of the dividing frame is provided with a stepped limiting structure, and the front end of the base is provided with a stepped structure that is adapted to the stepped limiting structure.

[0017] The stepped limiting structure extends downward to form a limiting member on its rear side, and the rear side of the stepped structure is provided with a slot that cooperates with the limiting member to limit the movement.

[0018] The upper side of the dividing frame is provided with a pressing surface, and the lower side of the base is provided with a pressing block that mates with the pressing surface.

[0019] The beneficial effects of this utility model are as follows: By integrating multiple independent wiring frames into the splitter frame, the single-phase output terminal has the ability to split multiple circuits. It eliminates the need to crimp multiple wires into one wire through crimping lugs, thereby saving the cost of crimping lugs, making wiring faster, and meeting the wiring requirements of different thicknesses.

[0028] 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.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain a specific posture (as shown in the attached figure).

[0030] like Figure 1 and Figure 2 As shown, this utility model discloses a measuring switch with multiple wiring frames, including a housing 100, an inlet terminal 300, and an outlet terminal 200. The housing 100 contains three mutually insulated phase wire channels 110 (corresponding to three phases), with an inlet terminal 300 and an outlet terminal 200 installed at both ends of each channel. This embodiment focuses on describing the outlet terminal 200.

[0031] like Figure 3 and Figure 4 As shown, the output terminal 200 includes a branch frame 210, four wiring frames, a first wiring board 230, and a second wiring board 231. The branch frame 210 is made of insulating material, with the wiring surface perpendicular to the bottom surface of the measuring switch. Four independent wiring channels 211 are formed on the wiring surface by partitions, and are divided into upper and lower rows. In this embodiment, the entire branch frame is integrally formed. Two sets of four locking channels 212 are provided in the direction perpendicular to the wiring channels 211. The four locking channels 212 are all located at the upper end of the branch frame and are connected to one wiring channel 211 respectively.

[0032] Four terminal blocks 220 (e.g., copper conductive blocks) are respectively embedded in four wiring channels 211. Each terminal block 220 is equipped with a tightening element 221 (e.g., a bolt), which is movably installed in a corresponding locking channel 212. The tightening element 221 is used to actuate the wire clamping plate to press the external wire inserted into the terminal block 220.

[0033] like Figure 5 and Figure 6As shown, the first terminal block 230 is a conductive metal plate, serving as the main conductive path. Its front end is connected to a second terminal block 231, and the two can be electrically connected through welding or integral molding. The front end of the first terminal block 230 branches directly to form two first branch terminal blocks 232, which extend into the two lower terminal frames 220 respectively. The front end of the second terminal block 231 branches to form two second branch terminal blocks 233, which extend into the two upper terminal frames 220 respectively. Thus, the main electrical path extends to four connection points through the first terminal block 230, the second terminal block 231, and their branch blocks.

[0034] To optimize space and avoid interference, the two wiring frames 220 in the same column (e.g., the front side) are staggered in the wiring depth direction (i.e., one in front of the other). Correspondingly, a through hole 234 is provided on the second wiring plate 231 at the position corresponding to the rear tightening member 221, so that the tightening member can pass through and press the wires extending into the lower wiring frame. At the same time, if the two wiring frames on the upper side are used, the tightening members of the corresponding lower wiring frames also need to be tightened downwards.

[0035] The housing 100 includes a base and a pedestal, and the base and pedestal cooperate to form an installation space for accommodating the outgoing terminal 200. The two cooperate to fix and limit the outgoing terminal, preventing the outgoing terminal from coming out or shifting.

[0036] The bottom of the dividing frame 210 is provided with a stepped limiting structure 213, and the front end of the base is provided with a stepped structure 120 adapted to the stepped limiting structure, such as... Figure 7 As shown, this implements front-end limiting during installation.

[0037] The stepped limiting structure 213 extends downward to form a limiting member 214. The stepped structure 120 has a slot 130 on its rear side that forms a limiting fit with the limiting member 214. During assembly, the limiting member 214 is inserted into the slot 130 to achieve rear-end limiting. Through the front and rear limiting fit, the front and rear direction limiting of the dividing frame in the base is achieved.

[0038] The upper side of the dividing frame 210 is provided with a pressing surface 215, and the lower side of the base is provided with a pressing block 150 that mates with the pressing surface 215. Figure 8 As shown. The branch frame also has a topmost crimping surface, which, through multiple crimping surfaces cooperating with the crimping blocks of the base, limits its vertical movement. Preferably, a limiting groove 216 is provided on the outside of the locking channel, the limiting groove being arranged along the vertical direction, and a corresponding limiting block 150 is provided on the base. When the base and the base are engaged, they form a front-to-back limiting effect on the upper end of the branch frame, ensuring that the branch frame is more firmly fixed, thereby securely confining the entire outgoing terminal 200 within the installation space.

[0039] This invention is simple to operate; simply insert the required external wires into the wiring frame and tighten the corresponding screw fasteners 221 with a screwdriver to complete the connection. This invention features a compact structure, flexible wiring, and reliable fixing, making it particularly suitable for power distribution applications with limited space and requiring multiple branch connections.

[0040] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
