Detailed Implementation

[0022] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Please see Figures 1 to 5 The relay 100 provided in this embodiment of the present utility model includes a base 10 and a contact portion 20.

[0027] The base 10 is provided with a placement groove 11, which extends through the base 10 in the X direction. The placement groove 11 forms a placement opening 12 on the side of the base 10 in the Y direction. The X and Y directions are perpendicular to each other. The contact portion 20 includes a foot 21 for connecting an external load. The foot 21 is configured to pass through the placement opening 12 in the Y direction and be placed in the placement groove 11.

[0028] The relay 100 described above forms a placement opening 12 on the side of the placement groove 11 for mounting the terminal 21 on the base 10. This allows the terminal 21 to be inserted into the placement groove 11 from the placement opening 12 in the Y direction when it is inserted into the base 10. When the terminal 21 is installed in the placement groove 11, the placement position of the terminal 21 can be clearly observed, improving the installation accuracy of the terminal 21. At the same time, it avoids the situation where more debris is generated due to excessive friction with the groove wall of the placement groove 11 when the terminal 21 is inserted from top to bottom in the X direction.

[0029] It should be noted that the X, Y, and Z directions are used to explain the structure of relay 100 and are not intended to be limiting. Furthermore, the structure of relay 100 also includes a magnetic drive system, a push structure, and the contact portion 20 includes a moving contact 212 and a stationary contact 213 on its terminals 21. The contact portion 20 also includes a spring 22 disposed on the moving contact 212 and a moving contact 23 disposed on the spring 22, and a stationary contact 24 disposed on the stationary contact 213.

[0030] The magnetic drive system includes a coil frame, a coil, an iron core, an armature, and a yoke. The iron core is inserted into the coil frame along its axial direction, and the coil is wound around the coil frame. The drive structure is rotatably mounted on the base 10. When the coil is energized or de-energized, the moving contact 23 and the stationary contact 24 on the drive spring 22 close or move away to connect or disconnect the external load. To enable electrical connection with the external load, after the end 21 is mounted on the base 10, it protrudes from the base 10 along the X direction.

[0031] In this embodiment, the placement groove 11 and placement opening 12 on the base 10 can be formed by directly removing part of the material of the base 10 from its side wall to create the placement groove 11 and placement opening 12. In another embodiment, the base 10 can be used as the main body, and a separate structure for creating the groove can be formed on the base 10 to create the placement groove 11.

[0032] Specifically, please refer to Figure 1 , Figure 2 as well as Figure 5 The base 10 in this embodiment includes a main body 13 and a mounting structure 14 disposed on one side of the main body 13. The main body 13 is used to mount the magnetic drive system and the push structure. The height of the mounting structure 14 in the X direction is less than the height of the main body 13 in the X direction, thereby forming a clearance notch for setting the positions of the moving contact 23 and the stationary contact 24. The mounting structure 14 forms a placement groove 11 and a placement opening 12. In this way, a separate mounting structure 14 is formed on the main body 13 in a grooved manner, which can ensure the structural strength of the entire base 10 compared to directly grooved on the side wall of the base 10.

[0033] Please see Figures 2 to 5To improve the installation efficiency of inserting the end foot 21 into the placement groove 11, the end foot 21 is provided with a first positioning structure 211, and the groove wall of the placement groove 11 is provided with a second positioning structure 15. The first positioning structure 211 and the second positioning structure 15 are interlocked and cooperated. In this way, when the end foot 21 is inserted from the placement port 12 into the placement groove 11, the positioning cooperation between the first positioning structure 211 and the second positioning structure 15 can achieve precise installation of the end foot 21, which not only improves the installation efficiency, but also improves the installation accuracy.

[0034] Furthermore, when the first positioning structure 211 and the second positioning structure 15 are configured, the first positioning structure 211 is disposed on the side of the end foot 21 facing the base 10 along the Y direction, and the second positioning structure 15 is disposed on the groove wall of the placement groove 11 facing the end foot 21 along the Y direction, thereby facilitating direct alignment of the end foot 21 into the placement groove 11 when it is inserted along the Y direction. In other embodiments, the first positioning structure 211 can also be disposed on the side of the end foot 21 along the Z direction, for example, on one or both sides of the end foot 21 along the Z direction. Correspondingly, the second positioning structure 15 is disposed on the groove wall of the placement groove 11 along the Z direction. When the end foot 21 is inserted into the placement groove 11, the first positioning structure 211 can be directly aligned with the second positioning structure 15 before insertion, which can also improve installation efficiency.

[0035] In some embodiments, the first positioning structure 211 can be configured as a positioning groove and the second positioning structure 15 can be configured as a positioning block; or in another embodiment, the first positioning structure 211 can be configured as a positioning block and the second positioning structure 15 can be configured as a positioning groove, both of which can achieve the effect of positioning and installing the two.

[0036] Furthermore, when setting the first positioning structure 211 on the end foot 21 and setting the second positioning structure 15 in the placement groove 11, only one quantity can be set, or two or three quantities can be set respectively, which is not limited here.

[0037] Specifically, please refer to Figures 1 to 5 In this embodiment, the positioning structure is configured such that the first positioning structure 211 is a positioning block and the second positioning structure 15 is a positioning groove. Thus, by setting a positioning block on the end foot 21, the structural strength of the end foot 21 can be increased.

[0038] Further, please refer to Figure 4 and Figure 5When a positioning groove is formed in the placement groove 11, two spaced-apart locking blocks 16 are provided on the groove wall of the placement groove 11 along the X direction, and a positioning groove is formed between the two locking blocks 16. In this way, by setting two locking blocks 16 to form a positioning groove between them, it is convenient to set the positioning groove in the placement groove 11 during injection molding, and at the same time, it can also improve the structural strength of the entire mounting structure 14. In other embodiments, the wall thickness at the location where the placement groove 11 is set can be set to be less than the thickness at other locations to form the positioning groove, which is not limited here.

[0039] Furthermore, to facilitate the installation of the end foot 21 on the base 10, a first positioning structure 211 is provided on both sides of the end foot 21 along the Y direction. This allows the end foot 21 to be inserted into the placement groove 11 along the Y direction when it is installed on the base 10, eliminating the need to identify the orientation of the first positioning structure 211 on the end foot 21 and improving installation efficiency. In other embodiments, the first positioning structure 211 can also be provided on one side of the end foot 21 along the Y direction to facilitate the shaping of the end foot 21.

[0040] Please see Figure 1 and Figure 3 In one embodiment of this utility model, the contact portion 20 includes at least one contact group, which includes four pins 21. The four pins 21 are two moving contact pins 212 and two stationary contact pins 213, respectively. One moving contact pin 212 and one stationary contact pin 213 are correspondingly arranged, and the two moving contact pins 212 are positioned between the two stationary contact pins 213 along the Z-direction. Further, the contact system also includes a spring 22. One end of the spring 22 is connected to the moving contact pin 212, and the other end is used to mount a moving contact 23. One end of the stationary contact pin 213 is used to mount a stationary contact 24. The stationary contact 24 and the moving contact 23 can be closed or opened. In this embodiment, the moving contact pins 212 and the stationary contact pins 213 are mounted in the same manner.

[0041] In the configuration of the two moving contact feet 212 and the two stationary contact feet 213, the two moving contact feet 212 are positioned between the two stationary contact feet 213 along the Z direction, that is, the two stationary contact feet 213 are positioned outside the two moving contact feet 212. Since the spring 22 on the moving contact feet 212 will undergo elastic deformation under the action of the pushing structure, the way of positioning the two moving contact feet 212 between the two stationary contact feet 213 along the Z direction can provide space for the spring 22 to deform.

[0042] Specifically, in this embodiment, a contact group is provided on each of the opposite sides of the base 10 along the Y direction.

[0043] The relay 100 described above facilitates the insertion of the terminal 21 into the base 10 by forming a placement opening 12 on the base 10 along the Y direction in the placement groove 11 for mounting the terminal 21, which not only improves the installation efficiency but also the installation accuracy. By setting a first positioning structure 211 on the terminal 21 and a second positioning structure 15 in the placement groove 11, the installation position of the terminal 21 can be positioned, further improving the installation efficiency and installation accuracy.

[0044] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
