Description

Technical Field

[0001] This utility model relates to the field of relay installation, and in particular to a magnetic latching relay base. Background Technology

[0002] Magnetic latching relays utilize permanent magnets or internal magnetic circuit design to maintain their original state after the control pulse disappears, without requiring continuous power. During installation, the relay base is used to mount and connect the relay accessories, providing electrical interfaces, mechanical fixation, and protection functions, simplifying relay replacement and maintenance.

[0003] When installing relays, common relay bases have mounting slots. The relay is usually directly clipped into the mounting slot, and the relay is fixed by the frictional resistance between the inner wall of the mounting slot and the relay, as well as the clamping components on the base. However, this method lacks a limiting function for the relay, which affects the stability of the relay installation. Utility Model Content

The limiting block drives the sliding block to move vertically upward to the movable groove position, allowing the sliding block to rotate within the movable groove cavity. This rotates the limiting block to a horizontal position, and then moves it downward, fixing the upper surface of the relay in place. The screw is then rotated, causing the pushing block to move vertically, pushing one end of the two pressing blocks. The pressing blocks push the fixing block and the locking block outward, causing one end of the locking block to insert into the slot cavity, thus positioning and fixing the limiting block. This ensures stable limiting of the relay by the limiting block and facilitates the installation of relays of different sizes. Attached Figure Description

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.

[0040] This utility model provides, for example Figures 1-6The magnetic latching relay base shown includes a base body 1, a mounting base 2, a limiting structure 3, and a positioning structure 4.

The mounting base 2 is located on one side of the upper surface of the base body 1, and the relay is slidably inserted into the inner cavity of the mounting base 2. The limiting structure 3 is located on both sides of the top of the mounting base 2, limiting the upper surface of the relay and improving the stability of the base body 1 for relay installation. The positioning structure 4 is located between the mounting base 2 and the limiting structure 3, fixing the limiting structure 3. The positioning structure 4 positions and fixes the limiting structure 3, facilitating the adjustment of the position of the limiting structure 3 and the installation of relays of different sizes.

[0041] Specifically, the limiting structure 3 includes a mounting groove 31, which is located on one side of the top of the card holder 2 and is used to mount a limiting block 32; a limiting block 32, which is slidably inserted into the inner cavity of the mounting groove 31 and is elongated, sliding within the inner cavity of the mounting groove 31 to limit the upper surface of the relay; and a sliding groove 33, located on one side of the inner wall of the mounting groove 31 and used to mount a sliding block 34; and a sliding block 34, one end of which is fixedly connected to one side of the bottom of the limiting block 32, and the other end of which is slidably inserted into the inner cavity of the sliding groove 33. Block 34 is square in shape and slides within the inner cavity of sliding groove 33 as limiting block 32 moves. Movable groove 35 is located at the top of sliding groove 33, and its diameter is larger than the width of sliding groove 33. Movable groove 35 is used for the rotation of sliding block 34. When limiting block 32 moves sliding block 34 vertically upward to the position of movable groove 35, sliding block 34 rotates within the inner cavity of movable groove 35, rotating limiting block 32 to the horizontal direction. Then, limiting block 32 moves downward, and sliding block 34 slides vertically downward along sliding groove 33, so that the outer wall of limiting block 32 fits against the upper surface of relay, thus limiting and fixing relay.

[0042] Furthermore, the positioning structure 4 includes slots 41, which are vertically spaced on the inner wall of the sliding groove 33 and are used to install the locking blocks 42; the locking blocks 42 are slidably inserted into the middle of the sliding block 34, with one end of the locking block 42 inserted into the inner cavity of the slot 41 and moving together with the limiting block 32 and the sliding block 34, and the other end being tapered. By sliding the other end of the locking block 42 into the inner cavity of one of the slots 41, the limiting block 32 and the sliding block 34 are limited and fixed; and a groove 43 is provided. At the bottom of the limiting block 32, a groove 43 is used to install the pushing block 48; a movable cavity is provided on both sides of the inner wall of the groove 43, and the movable cavity is used for the movement of the pressing block 46; a fixed block 45 is fixedly connected to the other end of the locking block 42, and the fixed block 45 is slidably inserted into the inner cavity of the movable cavity, and the fixed block 45 moves together with the locking block 42 to limit the locking block 42; a pressing block 46 is slidably inserted into the inner cavity of the movable cavity, one end of the pressing block 46 is set with an inclined surface, and the pressing block 46 slides in the inner cavity of the movable cavity. The following components are used to push the fixed block 45 and the locking block 42: a stop block 47, which is located at the top of the inner wall of the groove 43 and is used to limit one end of the pressing block 46. The stop block 47 is fixedly installed at the top of the inner wall of the groove 43 by mortise and tenon joints and is used to limit the movement of the pressing block 46 and prevent the pressing block 46 from separating from the movable cavity; and a push block 48, which is located in the inner cavity of the groove 43 and has inclined ends. The two ends of the push block 48 are respectively engaged with the pressing block 46 to push it, and the push block 48 moves vertically. The two pressing blocks 46 are pushed at one end, and the pressing blocks 46 push the fixing block 45 and the locking block 42 outward, so that one end of the locking block 42 is inserted into the inner cavity of the locking groove 41; the screw 49 has one end rotatably connected to the top of the inner wall of the groove 43, and a stop ring is provided between the top of the screw 49 and the top of the groove 43. The screw 49 is rotatably connected to the inner wall of the groove 43 through the stop ring to prevent the screw 49 from falling out of the groove 43. The screw 49 is threadedly connected to the middle of the pushing block 48. By rotating the screw 49, the pushing block 48 is driven to move in the vertical direction.

[0043] The extrusion block 46 is arranged in a square block shape, and the push block 48 is arranged in a long strip shape. The outer walls of both ends of the push block 48 are in contact with the inner wall of the groove 43. The inclined surface of one end of the extrusion block 46 is in contact with the inclined surface of the push block 48. The end face of the push block 48 is in contact with the inner wall of the groove 43.
