Description

Technical Field

[0001] This utility model relates to safety electrical equipment, specifically to a bridge-type flat relay. Background Technology

[0002] A relay is a circuit safety control device. One type of relay works by using an incoming current to induce electromagnetic induction in an electromagnetic coil, which in turn moves the moving iron core and moving contact. This causes the moving contact to connect to different stationary contacts via a bridge, thus controlling the circuit's on / off state by establishing conduction between different terminals. Chinese patent document (publication number: CN212967547U; publication date: April 13, 2021) discloses a double-gang DC conversion relay. Referring to its specification and drawings, its four terminals are arranged at the four corners, a common arrangement for similar relays on the market. This arrangement has several problems: Firstly, external wiring becomes complex, prone to cross-wiring, cumbersome, and poses certain safety hazards. Secondly, to accommodate the two terminals arranged at the front and rear, the internal stationary and moving contact assemblies require significant installation space, especially in the width of the housing, resulting in a larger housing size, making installation in certain locations or confined spaces inconvenient. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide a bridge-type flat relay for solving the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A bridge-type flat relay includes a housing, wherein the housing has an outwardly extending positive power terminal, a negative power terminal, and a load terminal, wherein there are two load terminals respectively located near the left and right sides of the housing, characterized in that the positive power terminal and the negative power terminal are arranged side by side near the rear side of the housing.

[0006] The housing contains an L-shaped positive stationary contact and a negative stationary contact. The short side of the positive stationary contact is connected to the positive terminal of the power supply, and the long side of the positive stationary contact is engaged with the moving contact assembly. The short side of the negative stationary contact is connected to the negative terminal of the power supply, and the long side of the negative stationary contact is engaged with the moving contact assembly.

[0007] The positive power supply terminal, negative power supply terminal, and load terminal are arranged in a basically straight line.

[0008] Mounting arms extend from both sides of the outer casing, and a first mounting groove is provided on the mounting arm. A second mounting groove is provided on the rear side of the outer casing near the middle of the bottom end.

[0009] The aforementioned technical solution provides a bridge-type flat relay. By arranging the positive and negative power supply terminals side-by-side near the rear of the housing, this arrangement simplifies the external wiring, reduces the likelihood of wiring tangling, simplifies wiring operations, and enhances the safety of the wiring layout. Furthermore, by changing the position of the terminals and using L-shaped stationary contacts, the required installation space inside the housing is effectively reduced, decreasing the overall width of the housing and resulting in a flatter shape. This facilitates product flattening and miniaturization, making it easier to install in narrow spaces or specific locations. Attached Figure Description

[0013] Figure 3 for Figure 1 Another perspective. Detailed Implementation

[0014] As shown in the figure, this utility model discloses a bridge-type flat relay, including a housing 4. Inside the housing 4 are outwardly extending positive power supply terminal 2, negative power supply terminal 3, and load terminal 1. There are two load terminals 1, respectively located near the left and right sides of the housing 4. The positive power supply terminal 2 and negative power supply terminal 3 are arranged side-by-side near the rear side of the housing 4. Inside the housing 4 are L-shaped positive stationary contact 7 and negative stationary contact 8. The short side of the positive stationary contact 7 is connected to the positive power supply terminal 2, and the long side of the positive stationary contact 7 engages with the moving contact assembly 5. The short side of the negative stationary contact 8 is connected to the negative power supply terminal 3, and the long side of the negative stationary contact 8 engages with the moving contact assembly 5. The load terminal 1 is connected to the U-shaped terminal block 6. The moving contact in the moving contact assembly 5 drives the iron core through an internal electromagnetic coil, which in turn moves the moving contact to connect with the positive terminal stationary contact 7 or the negative terminal stationary contact 8 of the power supply, thus switching the circuit. The positive terminal terminal 2, the negative terminal terminal 3, and the load terminal 1 are basically arranged in a straight line, further improving the neatness of the terminal arrangement. Mounting arms 9 extend from both sides of the outer casing 4. The mounting arms 9 have first mounting slots 10, and a second mounting slot 11 is provided on the rear side of the outer casing 4 near the middle of the bottom. This structure allows for installation using either the first mounting slots 10 on both sides or the second mounting slot in the middle, making the installation position more flexible.

[0015] This utility model's structure, by arranging the positive power terminal 2 and the negative power terminal 3 side-by-side near the rear of the housing, makes the overall external wiring simpler, reduces the likelihood of wiring tangling, facilitates wiring operations, and further enhances the safety of the wiring layout. In addition, by changing the position of the terminals and using L-shaped stationary contacts, the installation space required inside the housing is effectively reduced, the overall width of the housing is reduced, and the housing becomes flatter, which is conducive to product flattening and miniaturization, and thus facilitates installation in narrow spaces or specific locations.
