Description

Technical Field

[0001] The utility model relates to the technical field of circuit control, in particular to a base for simplifying the assembly of electromagnetic relays. Background Art

[0002] A relay is an electrical control device, usually applied to an automatic control circuit. It is actually an "automatic switch" that uses a small current to control the operation of a large current, and plays roles such as automatic regulation, safety protection, and circuit conversion in the circuit.

[0003] Publication (Announcement) No.: CN216311682U discloses a base for simplifying the assembly of electromagnetic relays, including a relay main board, a mounting base, a docking component, and a plug body. The mounting base is fixedly connected to the top of the relay main board. Square hollow blocks are fixedly connected to both sides of the mounting base, and wedge-shaped locking blocks are arranged inside the square hollow blocks; a mounting plate is fixedly connected to the bottom of the docking component, a clamping block is fixedly connected to the bottom of the mounting plate, the clamping block is movably clamped inside the mounting base, clamping grooves are formed on both sides of the clamping block, the wedge-shaped locking block is movably clamped in the clamping groove, and a socket main body is formed on the side wall of the docking component; a cable main body is fixedly connected to the plug body, and the plug body is movably clamped in the socket main body. This kind of base makes the clamping block of the docking component inserted into the mounting base in a plugging and matching manner, and then uses the wedge-shaped locking block to be clamped in the clamping groove of the clamping block to realize the stable connection between the docking component and the mounting base and prevent the two from separating. Although this method can achieve the stable connection between the docking component and the mounting base, there are defects, which are reflected in the square slider that facilitates the user to drive the wedge-shaped locking block to move. Because this kind of locking structure has two and is symmetrically distributed on both sides of the mounting base, but there is no stop structure between the two locking structures, resulting in that when the user unlocks the docking component, both hands need to control the corresponding locking structures respectively, so that the two wedge-shaped locking blocks can be simultaneously disengaged from the clamping grooves of the clamping block to unlock the clamping block. However, since both hands are used to drive the locking structures, there is no hand to take out the clamping block from the mounting base, so an auxiliary fixture is still needed, that is, the docking component is clamped in the auxiliary fixture and used as a third hand. This process is relatively cumbersome, and the fixture will damage the surface of the docking component. Summary of the Utility Model

[0004] The utility model aims to solve the above-mentioned shortcomings of the prior art and provides a base for simplifying the assembly of electromagnetic relays to solve the above problems.

[0005] The technical solution adopted by the present utility model to solve its technical problems: This base for simplifying the assembly of an electromagnetic relay includes a relay main board, a mounting base, and a docking component. The mounting base is provided with two square hollow blocks symmetrically distributed on both sides of the relay main board. A movable first moving block is arranged inside the square hollow block. A wedge-shaped locking block is arranged on the first moving block. A clamping groove for inserting the wedge-shaped locking block is arranged on the side of the clamping block of the docking component corresponding to the wedge-shaped locking block. The relay main board is provided with a movable moving component at a position behind the mounting base, and the number of the moving components matches that of the first moving blocks. The moving component is connected to the first moving block so that when either of them moves, the other follows and moves synchronously. A holding unit is arranged between the two moving components. The holding unit allows combination with the moving component and keeps the wedge-shaped locking block in an unlocked state when combined.

[0006] For further improvement, the moving component includes a moving part and a connecting arm. The moving part moves in a first moving groove arranged on the relay main board and the extending direction of which is consistent with the moving direction of the first moving block.

The fourth moving block moves in the third moving groove, and a spring with an elastic compression amount when the fourth moving block moves downward is arranged in the third moving groove.

[0012] The beneficial effects of the present utility model are as follows:

[0013] In the present utility model, the driving points of the first moving blocks are arranged at the rear end of the mounting base, which solves the problems of the large distance between the two first moving blocks and the presence of separators, and also facilitates cooperation with the holding unit, enabling the wedge-shaped locking blocks to remain in the unlocked state after unlocking. In this way, when disassembling the assembly of the mounting base and the docking element, there is no need to rely on auxiliary fixtures, which is convenient and fast. Description of the Drawings

[0019] The present utility model will be further described below with reference to the drawings:

[0020] Referring to the attached drawings: The base for simplifying the assembly of an electromagnetic relay includes a relay main board 1, a mounting base 2, and a docking element 3. The mounting base 2 is provided with two symmetrically distributed square hollow blocks 4 on the relay main board 1. A movable first moving block 41 is arranged inside the square hollow block 4. A wedge-shaped locking block 41-a is arranged on the first moving block 41. A clamping groove for inserting the wedge-shaped locking block 41-a is arranged on the side of the clamping block 31 of the docking element 3 corresponding to the wedge-shaped locking block 41-a. The relay main board 1 is provided with a movable moving assembly 5 at a position behind the mounting base 2, and the number of the moving assemblies 5 matches that of the first moving blocks 41. The moving assembly 5 is connected to the first moving block 41 so that when either of them moves, the other follows and moves synchronously. A holding unit 6 is arranged between the two moving assemblies 5. The holding unit 6 allows combination with the moving assembly 5 and keeps the wedge-shaped locking block 41-a in an unlocked state when combined. The principle of the present utility model is that the moving assembly 5 is used to connect with the first moving block 41. Its arrangement at the rear end position of the mounting base 2 solves the problems of the large distance between the two first moving blocks 41 and the presence of a separator. Moreover, the moving assembly 5 is also movable, and the moving direction is the same as that of the first moving block 41. In this way, when the moving assembly 5 moves, the first moving block 41 will also follow and move. At the same time, it is also convenient for the cooperation between the moving assembly 5 and the holding unit 6. The holding unit 6 is used to keep the wedge-shaped locking block 41-a in the unlocked state after unlocking. In this way, when disassembling the assembly of the mounting base 2 and the docking element 3, it is not necessary to use an auxiliary fixture, which is more convenient compared with the prior art.

[0021] The moving assembly 5 includes a moving part 51 and a connecting arm 52. The moving part 51 moves in a first moving groove 11 arranged on the relay main board 1 and whose extending direction is the same as the moving direction of the first moving block 41. One end of the connecting arm 52 is connected to the moving part 51, and the other end is connected to the first moving block 41. The moving part 51 enables the moving assembly 5 to have the ability to move, and the connecting arm 52 is used to connect the moving part 51 and the first moving block 41. In this way, when the first moving block 41 moves, the moving part 51 can follow and move. The first moving groove 11 provides moving guidance and moving restraint for the moving part 51, so that the moving direction of the moving part 51 is the same as that of the first moving block 41. The moving restraint avoids problems such as shaking of the moving part 51 during movement, which interfere with the smoothness of movement.

[0022] The first moving groove 11 has a narrow groove section 11-a communicating with the upper end surface of the relay main board 1 and a wide groove section 11-b communicating with the lower end surface of the relay main board 1. The moving part 51 has a second moving block 51-a moving in the wide groove section 11-b, a moving rod 51-b moving in the narrow groove section 11-a and extending to the upper end of the relay main board 1, and a connecting block 51-c integrally formed on the moving rod 51-b and connected to the connecting arm 52. The moving rod 51-b and the second moving block 51-a are connected by bolts. The first moving groove 11 is arranged in such a way that it has a stepped configuration, that is, narrow at the top and wide at the bottom, so as to restrict the moving part 51 therein to prevent the moving part 51 from disengaging. The moving part 51 is arranged in such a way that on the one hand, it matches the configuration of the first moving groove 11, and on the other hand, it has a part for connecting with the connecting arm 52, that is, both ends of the connecting arm 52 are inserted and matched with the first moving block 41 and the connecting block 51-c respectively.

[0023] On the rear end face of the mounting base 2, there is a second moving groove 21 arranged in the same direction as the moving direction of the second moving block 51-a and matching the number of the moving components 5. On the connecting block 51-c, there is a third moving block 51-c1 moving in the second moving groove 21. Such an arrangement makes the whole moving component 5 move more smoothly and also provides lateral support for the connecting block 51-c.

[0024] The connecting arm 52 has an L-shaped configuration and is provided with a reinforcing rib 52-a. Such an arrangement can increase the structural strength of the connecting arm 52 so that it can resist the resistance generated by the spring in the square hollow block 4 that enables the first moving block 41 to have self-resetting ability due to compression deformation.

[0025] The holding unit 6 includes a holding rod 61 and plugs 62 extending from both ends of the holding rod 61 in different extending directions. The holding rod 61 has a length that satisfies the separation distance presented by the two moving components 5 when the wedge-shaped locking block 41-a is in the unlocked state. On the connecting block 51-c, there is a socket 51-c2 for the plug 62 to be inserted into, so that when the two are combined, the holding rod 61 can stably exist between the two moving components 5. The holding rod 61 has a length matching the unlocked state of the wedge-shaped locking block 41-a. In this way, the combination of the plug 62 and the socket 51-c2 can keep the unlocked state of the wedge-shaped locking block 41-a all the time.

[0026] A fourth moving block 61-a is provided on the holding rod 61, and a third moving groove 22 with a moving direction perpendicular to the moving direction of the moving component 5 is provided on the rear end face of the mounting base 2. The fourth moving block 61-a moves within the third moving groove 22, and a spring 7 with an elastic compression amount when the fourth moving block 61-a moves downward is provided within the third moving groove 22. Such a setting can not only keep the holding rod 61 on the mounting base 2, but also make the holding rod 61 movable. That is, when the wedge-shaped locking block 41-a is in the unlocked state, use the thumbs of both hands to respectively control the corresponding moving components 5 to move in the unlocking direction. After the moving components 5 move in place, then simultaneously act on the holding rod 61 with the index fingers of both hands, and then apply a downward pressure simultaneously to make the holding rod 61 move downward. Since the first moving block 41 of the wedge-shaped locking block 41-a is self-reset by the spring, when the holding rod 61 is located between the two connecting blocks 51-c, the user can release both hands, so that the plug 62 abuts against the outer peripheral surface of the connecting block 51-c. Finally, adjust the position of the holding rod 61 so that the plug 62 is inserted into the socket 51-c2 to keep the wedge-shaped locking block 41-a in the unlocked state. The function of the spring 7 is that when the holding state is released, the holding rod 61 can move to the initial position by itself.

[0027] Although the present utility model has been illustrated and described by reference to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details may be made within the scope of the claims.
