[0002] Relays are the most common electronic components and are widely used in many fields of electronics and electrical engineering. They are the preferred switch parts for circuit boards. Relays mainly consist of two major mechanisms. One is the driving mechanism, and the other is the load mechanism. The driving mechanism is mainly the coil magnetic circuit of the relay, which is composed of a plastic skeleton, enameled wire, lead pins, iron core, yoke iron, armature, hook, etc. The load mechanism is mainly composed of a moving reed, a moving reed terminal, a moving contact, a static reed, and a static contact. The moving and static contacts are respectively stamped on the moving and static reeds, and the moving reed is combined with the moving reed terminal by stamping and assembled on a plastic base to bear the load.

[0003] For conventional relays, the base is used as the basic part, and all parts are installed on the base. Due to factors such as dimensional deviations between the assembly grooves of the base, when assembling relay parts, most of them use manual methods to compensate for the dimensional deviations of the base, which occupies a large amount of labor costs and it is difficult to improve the efficiency. Therefore, the utility model proposes a relay with quick assembly to solve the problems existing in the prior art. Summary of the Utility Model

[0004] Aiming at the above problems, the purpose of the utility model is to provide a relay with quick assembly, which has the advantage of being easy to assemble and can solve the problems in the prior art.

[0021] To deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0022] According to Figures 1 - 5 As shown, this embodiment proposes a relay with quick assembly, including a base 1, on which a load component mounting seat 2 is installed. The load component mounting seat 2 and the base 1 are integrally formed to form a load mechanism pre-assembly. Thus, in the production process of the relay, only the driving component and the other parts of the load component need to be installed at the predetermined positions one by one, which is very convenient.

[0023] Specifically, a load component is installed on the load component mounting seat 2. The load component includes a moving reed 13 and a static reed 14. Contacts 15 are installed on both the moving reed 13 and the static reed 14. Slots 16 are provided on the load component mounting seat 2 below the moving reed 13 and the static reed 14, and are respectively connected to the corresponding slots 16 at the corresponding positions. That is, according to the positions of the slots 16 on the load component mounting seat 2, the corresponding moving reed 13 and static reed 14 can be installed. In this embodiment, pins are installed at the lower ends of the moving reed 13 and the static reed 14, and the pins pass through the base 1 and extend below the base 1.

[0024] The load component mounting seat 2 is provided with a mounting groove 3, and a bottom plate 4 is provided at the bottom of the mounting groove 3. The function of the mounting groove 3 is to mount the yoke 8. After the yoke 8 is mounted, its lower end contacts the bottom plate 4, and then other components are assembled in sequence. Two sets of symmetrically arranged convex structures 5 are provided in the corresponding mounting groove 3. First clamping grooves 6 and second clamping grooves 7 are provided in the mounting groove 3 on both sides of the convex structure 5 respectively. The first clamping groove 6 is used for the limit of the yoke 8, that is, the yoke 8 is mounted in the mounting groove 3. As Figure 3 shown, a second boss 12 is mounted on the yoke 8, and several groups of the second bosses 12 are provided. In this embodiment, there are four evenly distributed groups of the second bosses 12, which are grouped in pairs and located on both sides of the yoke 8. The corresponding second bosses 12 contact the load component mounting seat 2. Thus, after the yoke 8 is mounted, one side of it contacts the convex structure 5, and the other side contacts the load component mounting seat 2 through the second boss 12 (at this time, the second boss 12 is located in the first clamping groove 6). Thus, the limit of the yoke 8 is formed, enabling it to only move up and down in the mounting groove 3, ensuring that the yoke 8 will not shake left and right after being mounted. Further, a first boss 11 is mounted in the housing 10 above the yoke 8, and several groups of the first bosses 11 are provided. In this embodiment, two sets of the first bosses 11 are symmetrically provided. When the housing 10 is mounted, the first boss 11 contacts the yoke 8, which can clamp the yoke 8 to prevent it from moving upward. In this way, the stability of the yoke 8 after being mounted is ensured.

[0025] A driving component is mounted on the yoke 8, and the driving component is connected to the load component through the pushing card 9. As Figure 5 shown, the driving component includes a bobbin 17, an enameled wire 27 is sleeved outside the bobbin 17, and an iron core 18 is mounted inside the bobbin 17. The lower end of the iron core 18 contacts the yoke 8. An armature 19 is mounted on the yoke 8, and one end of the armature 19 is connected to the pushing card 9. Further, a hook 20 is provided inside the mounting groove 3, and both ends of the hook 20 are located in the second clamping grooves 7 at the corresponding positions. The hook 20 contacts the armature 19. Specifically, the enameled wire 27 is wound around the bobbin 17 in a certain number of turns in the circumferential direction to form a hollow cylinder. Two lead pins are fixed on the left and right of the bobbin 17 to lead out the start and end of the enameled wire 27 to form a circuit. This structure is called a coil. The iron core 18 passes through the hollow cylinder in the middle of the coil and is surrounded by the enameled wire 27. The yoke 8 and the iron core 18 are riveted and fixed together to form an electromagnet structure. The armature 19 is fixed at the head of the yoke 8, supported by the yoke 8, and fixed by the hook 20 to form a lever structure. This structure is the driving component.

[0026] An outer shell 10 is sleeved on the outside of the load component mounting seat 2. Buckles 24 are installed on both sides of the base 1, and bayonets 25 are provided on both sides of the outer shell 10. The bayonets 25 are adapted to the buckles 24. A third boss 26 is installed on the inner side of the outer shell 10, and several groups of the third bosses 26 are provided. In this embodiment, four groups of the third bosses 26 are evenly provided. That is, the outer shell 10 is connected to the base 1 by a clamping method, which facilitates the installation and disassembly of the outer shell 10.

[0027] At the same time, an insertion port 21 is provided on the load component mounting seat 2. An insertion block 22 is provided inside the insertion port 21, and the insertion block 22 is connected to the outer shell 10 through a fixing plate 23. When the outer shell 10 is installed, the lower end of the insertion block 22 contacts the pushing card 9, and at this time, the pushing card 9 is in a limited state, avoiding the situation that the pushing card 9 shakes up and down.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
